Bottle Biology

Bottle Biology Project I made a two-layered bottle ecosystem. In the bottom layer, there is an aquatic ecosystem. In the aquatic ecosystem, there is one organism; a goldfish. In the top layer, there is a land ecosystem. There are many plants and other pudding flowers. This is a good example of two organisms from different ecosystems. There were not as many steps as I thought there would be involved in building the bottle itself. First I emptied out two two liters of pop. I then cut off the tops of both bottles, and threw out one of the bases.In the leftover base, I poured water, aquatic gravel, and a fake plant for the fish. I then put the fish in it’s new happy home. In order to feed him, I cut out a flap leading to the water that I can put fish food in. After that, I began working on the top layer. I placed one of the tops, with the cap still on, about half an inch into the original base. I taped it securely into the base, to ensure that the whole upper layer would not crush the fish. Then I put my plants into the half-built top layer. After that I placed my second bottle top on top of the base, creating another funnel.I taped the top securely on, finishing the bottle. I can screw and unscrew the cap whenever I need to give the plant water. Both the fish and plant do not need much caring for. The plant needs a little bit of water every day, and the fish needs food about twice a day, but that is not nearly what I thought it would take to maintain these organisms. I enjoyed this project; it was very interesting to make two small ecosystems. If I had the chance to do it again with two different organisms I would definitely do it. ———————– AJ Keith 5/19/11 Period 3

Performance Rating Written Report

For example, If the benchmark of dealing 52 cards In 0. 0 minutes Is established, a complete and specific description should be given of the distance of the four hands alt with respect to the dealer, as well as the technique of grasping, moving and disposing of the cards. The benchmark example should be supplemented by a clear description of the characteristics of an employee carrying out a normal performance. A representative description of such an employee might be as follows: a worker who Is adapted to the work and has attained sufficient experience to perform the Job In efficient manner, with little or no supervision.The worker possesses coordinated mental and physical qualities, enabling him or her to proceed from one element to another without hesitation or delay, In accordance with the principles of motion economy. The worker maintains a good level of efficiency through knowledge and proper use of all tools and equipment related to the Job. He or she cooperates and performs at a pace best suited for continuous performance.However, Individual differences between workers still exist Differences in inherent knowledge, physical capacity, health, trade knowledge, physical dexterity, and training can cause one operator to outperform another consistently and progressively. Sound rating characteristics The first and most Important characteristic of any rating system Is ACCURACY. Perfect consistency in rating is impossible. The rating plan with variations greater than Ð’Â ± 5 percent should either be improved or replaced. Time study analysts who to conduct such studies.It is not difficult to correct the rating habits of an analyst who consistently rates high or consistently low. But it is very difficult to correct the rating ability of an analyst who is inconsistent, rating too high today and too low tomorrow. Inconsistency, more than anything else, destroys the operator's confidence in the time study procedure. A rating system that is simple, concise, easily explained, and keyed to well-established benchmarks is more successful than a complex rating system requiring involved adjustment factors and computational techniques that may confuse the average shop employee.Workstation rating Performance rating should only be done during the observation of elemental times. As the operator progresses from one element to the next, using the prescribed method, analyst should carefully evaluate speed, dexterity, false moves, rhythm, coordination, effectiveness, and the other factors influencing output. Once the performance has been Judged and recorded, it should not be changed. However, this does not imply that the observer always has perfect Judgment. If the rating is questioned, the Job or operation should be restudied to prove or disprove the recorded evaluation.Immediately after completing the study and recording the final performance factor if overall rating even elemental rating was used, the analyst can approximate the operator's performance. This gives the operator an opportunity to express his or her opinion about the fairness of the performance factor, and to give his opinion directly to the person responsible for its development. Rating elements versus Overall study On short-cycle repetitive operations, little deviation in operator performance is realized during the course of the average-length study (1 5 to 30 minutes).In such cases, it is perfectly satisfactory to evaluate the performance of the entire study and record the rating factor for each element. Remember power-fed or machine- controlled elements are rated normal, or 100, as their speed cannot be changed at will by the operators. In short-cycle studies, an observer who endeavors to reference rate each element in the study will be so busy recording values that he or she will be unable to effectively observe, analyze, and evaluate the operator's performance.When the study is relatively long (over 30 minutes) or is made up of several long elements, operator p erformance may vary during the course of the study. They can consistently and accurately rate elements longer than 0. 10 minute as they occur. If a study is comprised off series of elements shorter than 0. 10 minute, then no effort should be made to evaluate each element of each cycle of the study, as time does not permit such action. It is satisfactory to rate the overall time of each cycle or a group of cycles.RATING METHODS Speed rating – Is a performance evaluation method that only considers the rate of accomplishment of the work per unit time. In this method, the observer measures the effectiveness of the operator against the concept of a qualified operator doing the same work, and then assigns a percentage to indicate the ratio of the observed performance to performance determine whether it is above or below normal. 100 percent is usually considered normal.A rating of 110 percent indicates that the operator was reforming at a speed 10 percent greater than normal, and a rating of 90 percent would mean that the operator was performing at a speed 90 percent normal. Two tasks were suggested by Preserve (1957) to develop an initial mental model ; (1) walking 3 miles per hour (4. Km/her), that is, 100 feet (30. 5 m) in 0. 38 minutes and (2) dealing a deck of 52 cards into four equal piles closely spaced In one half minute. Time study analysts use speed rating for elemental, cycle, or overall rating.The Westinghouse system One of the oldest used rating system was developed by the Westinghouse Electric Corporation. Then termed leveling, it is outlined in detail in Lowry, Maynard, and Estrangement. This method considers four (4) factors in evaluating the performance of the operator: 1. Skill Lowry defines skill as † proficiency at following a given method,† and further relates it to expertise, as demonstrated by a proper coordination of mind and hands. A person's skill in a given operation increases over time, because increased familiarity with the work brings speed, smoothness of motions, and freedom from hesitations and false moves.The Westinghouse rating system lists these six degrees or lasses that represent an acceptable proficiency for evaluation: Poor, fair, average, good, excellent, and super. 2. Effort This rating method defines effort as a â€Å"demonstration of the will to work effectively. † Effort is representative of the speed with which skill is applied, and can be controlled to a high degree by the operator. The six effort classes for rating purposes are: Poor, fair, average, good, excellent, and excessive 3. Conditions In this performance rating procedure affect the operator and not the operation.Time study analyst rate conditions as normal or average in more than a majority of instances, as conditions are evaluated in comparison with the way they are customarily found at the workstation. Elements affecting working conditions include temperature, ventilation, light and noise. The six general classe s of conditions, with values ranging from +6 percent to -7 percent, are ideal, excellent good, average, fair, and poor. 4. Consistency Elemental time values that constantly repeat would have perfectly consistency.This situation occurs very frequently, as there always tends to be dispersion due to the and effort, erroneous watch readings, and foreign elements. The six classes f consistency are perfect, excellent, good, average, fair and poor. Perfect consistency is rated +4 percent and poor consistency is rated -4 percent. Once the skill, effort, conditions and consistency of the operation have been assigned, and their equivalent numerical values established. For example, if a given Job is rated CA on skill.CLC on effort, D on conditions and E on consistency, the performance factor would be as follows; The Westinghouse rating system demands considerable training to differentiate the levels of each attribute. The procedure generally followed is; 1 . A film is shown and he operation ex plained. 2. The film or tape is reshow and rated. 3. The individual ratings are compared and discussed. 4. The film or tape is reshow and the attributes are pointed out and explained. 5. Step 4 is repeated as often as necessary to reach understanding and agreement.Synthetic rating Morrow (1946) established a procedure known as synthetic rating. This procedure determines a performance factor for representative effort elements of the work cycle by comparing actual elemental observed times to times developed through fundamental motion data. The performance factor may be expressed algebraically HO Where; P= performance or rating factor. Fundamental motion time. 0= observed mean elemental time for the elements used in F. Objective Rating Developed by Mendel and Dander (1994), eliminates the difficulty of establishing a normal speed criterion for every type of work.This procedure establishes a single work assignment to which the pace of all other Jobs is compared. After the Judgment of pa ce, a secondary factor assigned to the Job indicates its relative difficulty. Factors (1) Amount of body used, (2) Foot pedals, (3) Femaleness, (4) Eye-hand coordination, (5) Handling or sensory requirements, and 6) Weight handled or resistance encountered. The rating (R) can thus be expressed as follows: where: P= Pace rating factor. Difficulty adjustment factor. Rating Application R=PIX job The value of a rating is written in the R column of the time study form.After the stopwatch phase is complete, the analyst multiplies the observed time (OR) by rating (R), scaled by 100, to yield the normal time (NT). RATING ANALYSIS TO X 100 Four criteria determine whether or not time study analyst using speed rating can consistently establish values within 5 percent of the rating average calculated by a rope of trained analyst. These are: 1. Experience in the class of work performed. 2. Use of synthetic benchmarks on at least two of the elements performed. 3.Selection of an operator who gives performances somewhere between 85 and 115 percent of standard pace. 4. Use of the mean value of three or more independent studies and/or different operators. To assure speed rating consistency, both with their own rates and with the rates established by the others, analyst should continually participate in organized training programs. One of the most widely used training methods is the observation of audiotapes or motion-picture films illustrating diverse operations performed at different productivity levels.Figure 10-3. A straight LINE indicates perfection, whereas high-irregularities on both sides of the line indicate inconsistency, as well as an ability to evaluate performance. The analyst rated the first film 75, but the correct rating was 55. The second was rated 80, while the proper rating was 70. In all but the first case, the analyst was within the company's established area of correct rating. Note, that due to the nature of confidence intervals, the Ð’Â ±5 percent accu racy criterion is valid only around 100 recent or standard performance.When performance is below 70 percent of standard or above 130 percent of standard, an experienced time study analyst would expect an error much larger than 5 percent. The closer the time study analyst's rating comes to the x-axis, the more correct he/she is. To determine quantitatively an analyst's ability to rate performance, compute the percentage of the analyst's rating contained within specified limits of the known ratings. This can be done as follows: 1 . Compute the mean difference ( CD )between the analyst's rating and the actual rating for n test (n should be at least 15 observations). Compute the standard deviation (SD )of the differences in rating 3. Compute the normal deviate(Z), where; 4. Compute the normal deviate (Z ), where; Z = +5 (or some other figure of accuracy) – CD 5. Compute the area under the normal distribution curve between Ð’Â ±5 (for some figure of accuracy) centered at CD, w hich is assumed to be equal to deed, and Sd which is assumed to be equal to ad Analyst overrated low performance levels and underrated high performance levels. This is typical of novice raters who tend to be conservative raters and afraid to deviate too far from standard performance.In statistical applications, this tendency is termed regression to the mean and result in a relatively flat line compared to the expected line with a slope of one. The novice rater who rates higher than the true value for performance below standard performance produces a loose rate. For performance above the standard, a novice rater who rates lower than the true value produces a tight rate. Straight Speed Rating The performance rating plan that is easiest to apply, easiest to explain and gives the most valid results. Rating Training -To assure speed rating consistency, both with their own rates and with the rates

To What Extent Was the Lack of Political Reforms the Main Cause of the 1905 Revolution

To what extent was the lack of political reforms the main cause of the 1905 revolution? The 1905 Revolution was brought about by Bloody Sunday, this attack from the Tsar’s army on innocent peaceful protestors was the trigger for the revolution. Many other reasons throughout the years leading up to 1905 lead to the revolution. To understand fully why the revolution took place you need to understand all of the political reforms or the fact that there were not enough. A main factor contributing to 1905 revolution was the power held by the Tsar, the peasants and workers did not agree with the autocracy that was pushed onto them. Before the revolution all other political parties were banned by the Tsar and were not allowed to form groups that were against the Tsar, any groups that did try to do this, their leaders were either killed or sent to camps in Siberia as political prisoners, this level of harsh treatment towards political opponents and because of this lack of political reform a large amount of resentment was felt towards the Tsar. The lack of a Parliament also left people in Russia pushing for change, and because of this, there was a real need for a reform to create a working parliament so that not all of the power was in the Tsars hands. To stop the 1905 Revolution, the Tsar realised he was going to have to give up some of his power and to try and reason with his people, or this is the picture that he painted with the October Manifesto, this contained some political reforms that relinquished some of his power and some reforms that gave peasants more independence and factory workers better conditions. This manifesto showed a reasonable level of political reform but he did not actually have any intention of giving any of his power up. By deploying the October Manifesto the Tsar actually calmed tempers of his opponents and satisfied them for a time. If the Tsar had stuck to these political reforms there would have been no more unrest through the country but because he went back on them, it in fact worsened the situation and because of the lack of reforms this again led to more and more uprising across Russia. All of the different political parties that started to develop across the country started to socially and economically advance, this was because of more and more middle class people thinking that their voices should be heard. These parties all had many different ideas for political reforms, but first of all they all wanted an nd to autocracy and political change to take place. There was also a major uproar about the Russo-Japanese war which ended in September 1905. This was a huge embarrassment for Russia who were supposed to be one of the great powers in the world and were defeated by an inferior force. This caused much anger throughout Russia because of the Russian people believing that Nicholas II was not able to lead th e country through a war. This was another contributing factor to the uprising of 1905. The loss of the war shocked the Russians and knocked the countries esteem and added to what was already a simmering tension within Russia. In turn this was one of the triggers to the revolution. There was a slight hope that came through with the October Manifesto with the chance of a Duma, but this was short lived, after Nicholas II closed the first two Dumas down after only three months of them starting. This was another case where a political reform that would have made a difference to Russia and helped keep the country under control was not used to its full extent and ended up mounting more anger towards the Tsar for going back on his word. His minister then made it near on impossible for any real threat to the Tsar to be involved in both the third and fourth Duma. During this time there was a huge growth in the industrial industry in Russia and there was a need for political change to be able to get better working conditions in factories. More and more factories were being built and because of the lack of reform leading to the revolution many workers were protesting about their safety, hours and conditions. A real lack of political reform was a main contributor to the 1905 Revolution, although the real trigger was the Bloody Sunday massacre there was throughout the beginning of the 20th century a growing anger and resentment felt towards the Tsar and the way he was leading the country. The reaction of the Tsar in the revolution led to resentment about the reforms in the October Manifesto as well due to him just turning back on them. Overall there was a definite lack of reforms leading up to and after the 1905 Revolution.

Retailing Essay Example | Topics and Well Written Essays - 5250 words

Retailing - Essay Example A significant segment of this retailing upheaval has taken place in the area of logistics where British retailers had taken over the supply chain, thereby, lessening the lead times from the manufacturing plant to the store. The grocery segment, particularly, possesses a stream-lined logistical system with investment into multiple distribution hubs and transport in order to provide with an increasing figure of super-stores. This logistical concept is now being confronted by the technological, environmental, and political transformations. The policy of government to reduce environmental harm, thereby, revitalizing town centres puts forward great challenges for logistics. As put forth by Clarke, the early stress on retailers along with store location activities offered to feign both the wider anatomy of the product channel and the stand of consumption in shaping retail transformation (Clarke, 1996). By the midst of the twentieth century, consumers had an associatively restrained option of stores and stocks for their major periodical shopping spree. Most of the market-places were inclusive of a choice that encompassed the conventional super-markets, convenience stores, and a deteriorating number of small neighbourhood food shops. Following that, during the 1970s, however, an out-and-out bash took place in the new types of retail formats. 1980 initiated the 'significantly differentiated' formats which were competent for the dollars of customers. This new choice was inclusive of hyper-marches, warehouse shops, super-combos, super-stores, and limited variety discount stores. Apparently, in the early 1980s, strategic and tactical positioning became critical matters for survival in the retail industry (Arnold et al, 1983). Here, we will discuss the challenges as put forth by the transformations that have taken place since the 1980s. Around a century ago, even as retailing was entirely different from what it is now, there were a number of big transformations of the twentieth century which were already there in their embryonic stage. For example, most of the products were named, if not 'branded' by the retailers, which gave rise to manufacturer branding. Also, retail operations experienced various novel technologies, chiefly in construction and transport, and had great impact on them. Moreover, international sourcing was previously being practiced in a restrained way, and city centres had started to embellish into major hubs of comparison retailing. Today, we know that the epoch is entirely business-oriented. In no time of the world history has it inhibited such a significant place for business as it is not comprised of, where it affords sufficient opportunity for the highest honours, for the most long-lasting fame, and for wealth and authority that has no limits. Retailing today, is an arena which is capable of a lluring the able ones and the ambitious who can practice their greatest talents. This

Slavery During American Revolution Essay Example | Topics and Well Written Essays - 750 words

Slavery During American Revolution - Essay Example The Arawaks also provided food, gifts and water to Christopher Columbus and his crew upon arrival in the territories of America. All these humane care and concern as displayed by Arawaks to Columbus and his group were senseless in ensuring continued peace and freedom among the communities of the Arawaks. These events as faced by Arawaks marked the sad the beginning of the slavery and American Revolution. Derived from the meek nature of the Arawaks, Columbus and his group developed mechanisms and ideas of converting innocent and peasant community into their slaves (Zinn 1). In the reports of Zinn (1), Columbus and his group were pleased with the good bodies of the Arawaks and the fact that they lacked dread weapons earned Columbus and his group much confidence to pursue and subdue the Arawaks in their own land. Zinn (1) connotes Columbus saying, â€Å"They have no iron. They got spears made of cane†¦they would make fine servants†. Columbus and his group had well wedged iro n weapons, which they even witnessed, cut one of the Arawaks when he received the weapon from the Columbus by holding the sharp edge. Columbus was also coined arguing that the ignorance of the Arawaks is the reason as to why the cut themselves with the iron. Columbus and his group on realizing that Baham island s were rich in precious gold, he resorted to engage forced slavery in the extraction process of the gold (Zinn 1). In order to enhance the power of his crew, Columbus travelled back to Italy with elements of gold to convince king to add him some other personalities to help him utilize the Arawaks in mining of the gold. Zinn (1) confirms that Columbus used his boosted force to compel the miserable Arawaks work in the mines and obtain him gold under slavery. Much work with insufficient food led to suffocation of the Arawaks thus leading to their death in large numbers. According to Zinn (1), Columbus also seized and enslaved a population of Indians in the Caribbean Island after he recognized that they were equally non-brutal. The enslaved Indians worked in the gold rich mines to excavate gold that were later transported to Europe. Many Indian however faced death due to their stubbornness to the Europeans. Those who could not work as slaves harmed and killed. Zinn (1) also confirms that Columbus picked 500 strong men among the Indian and Arawak communities to load gold into the ships and journey to Europe. Some of the slaves boarded on the ships in the reports of Zinn (1) died on the way to adverse cold weather in the ocean. Those who managed to reach Spain were sold as slaves to the rich households in Spain. Indians were forcibly compelled to gather gold in the depleted gold mines. Failure to collect sufficient amount called for mistreatment. Zinn (1) further reports that, the massive murder was directed to the Arawaks who tried to rebel against the Europeans. In addition, Indian and Arawaks under imprisonment faced merciless hanging by the Spaniard armie s (Zinn 1). In the views of Zinn (1), Pizarro one of the successors of Columbus conceded vehement killing of Indians whom he considered as scarifies to his gods. Indians would resist the domination of the Europeans to convert them into slaves. Indians’ resistance made Europeans to advance numerous attacks against the Indians, which included destruction of crops and death of people and animals. Zinn (2) reports that the white settlers in Virginia indulged in large

Why numbers matter - Essay Example The principles concerned with managing money are important to be taken into account while planning to save or invest money somewhere. To discuss and understand these principles, an article from Msnbc The Bottom Line dated November 06, 2011, ‘After steadying, home prices begin falling again’ has been taken into account which entails the scenario of the United States’ real estate industry. The author of the article tells about the falling prices of homes in the United States which were on a steady trend in the summer of 2011. He says that due to the imbalance between demand and supply, there are numerous houses unsold in many states of the US until the end of September 2011. This price fall is being observed by investors and analysts and they are waiting for these to be bottomed that is a rise is being expected after massive falls, though not in the short term. Considering the poor interest rates of US short term Treasury Bills; 0.005% for 3-months and 0.035% for 6-month bills as per the recent auction; this investment aspect has been kept on a farer side by many investors as the rate of return is minimal. Considering this point, other investment opportunities should be searched for. This shows that it is a nice time to buy some lower priced houses and benefit from the capital gains arising in the future, though not in the short term (Schoen, 2011). Taking control of finances is very crucial and an investor should read about some financial trends using mathematical concepts such as percentages and shares in different investments and then take calculated actions. This leads to the understanding of the compounding concept. Just as an investor determines the amount of investment he or she can do, he must take into account the related rate of return and use it to compound his or her future inflows from the investment over the concerned time period. The simple formula for it to be calculated is: Amount of investment * (1 +

Same-sex marriage Essay Example | Topics and Well Written Essays - 1000 words - 1

Same-sex marriage - Essay Example Same-sex marriage first became a reality in America in the year 2004, when the Supreme Court in Massachusetts actually ruled that it was necessary under the equal protections clause of the states Constitution. Connecticut in reality began permitting same-sex marriages in the fall of 2009. In April 2009, Iowas Supreme Court ruled in favor of permitting same-sex couples to marry, also giving advocates an important first victory in the nations heartland and thwarting the notion that only the Northeast will permit it. 7 April 2009 the Vermont Legislature made the difference. â€Å"Jim Douglass veto of a bill permitting gay couples to marry, mustering precisely enough votes to conserve the measure. This step made Vermont the first state to actually permit same-sex marriage through legislative action instead of the ruling of court.† (Boswell, John) Two more states--New Hampshire and New Jersey--recognize civil unions for same-sex couples; an intermediate step that supporters say has made same-sex marriage seem less scary. New England remains pivotal in same-sex marriage movement, with a campaign under way that will extend marriage rights to gay men and lesbians in all six of the regions states by 2012. The meaning of marriage gets completely redefined when two men marry each other and the same has become an issue that has come to the limelight. Gay marriage is a serious threat and it challenges the nature too and this is because two men can never reproduce and take their generation forward. They can adopt a child but they can never fulfill the gap left, that gap can only be fulfilled by a mother. The divorce rates are extremely high when two men or women marry each other and research goes to prove it. Heterosexual divorces are much less than homosexual divorces and this is another reason why people oppose gay marriages. Gay marriages have also come under intense scrutiny with regard to the tradition that the world has been following for many years. When

Personality Development Essay Example | Topics and Well Written Essays - 500 words

Personality Development - Essay Example In hoarding we see people who see the entire world as a possession that they must acquire, while the marketing orientation includes those who mold themselves to what they feel society’s image of them is, they dislike anything old and crave anything new. These are closely related to Horney’s moving against people orientation, where we see the need for power, control, and recognition They also are similar to Horney’s moving away from people orientation, which includes the need of autonomy, the need for perfection, the need of self sufficiency, and the need to feel better than others. Like all of Horney’s orientations, moving toward people is also fraught with needs: the need to be loved, the need to gain the approval of others, and the need to please others. Fromm’s last orientation, necrophilous, deals mainly with death and destruction, something that Horney does not touch on. Fromm’s one orientation that is positive is the productive one, whe re people continually learn to relate to the world and others in it, and learn to truly love, and have no fear of acceptance.

A Comparison between Walgreens and Wal-Mart Term Paper

A Comparison between Walgreens and Wal-Mart - Term Paper Example Both companies started off with core objectives of providing efficient services with regard to effective delivery of services in the drug retail sector. With time, both companies have grown to reputable companies with regard various service delivery practices related to the retailing industry. There exists a thin line with regard to the existence of service advantages of the services offered by both companies. Thus, in comparing and contrasting both companies, an individual requires the necessary content for effective realization of the service advantages. In addition, the employment of various analytic tools such as Porters’ 5 forces would provide the desired distinguishing edge. Founded by Charles R. Walgreen in 1901, Walgreens has grown to be one of the largest drug retailing companies in the U.S. according to its official website; the company currently boasts of over 8000 locations across the nation. This represents a significant expansion of the company from its headquart ers in Chicago, Illinois. Thus, the company provides services with regard to pharmacy, health and wellness. The company’s provision of these services is championed by the employment of various drugs stores and health service divisions in the country. Walgreens owes its origin to the establishment of small drug store in Chicago, Illinois in the early XX century. By the 1920s, the company’s stores had incurred a tremendous growth. ... Thus, according to the company’s official website, the company operates various departmental and warehouse stores around the world. The company has grown to be the leading retailer globally and the third largest public corporation. With more than 2 million employees around the world, the company boasts of the largest employee base in the in the globe. Headquartered in Bentonville, Arkansas, Wal-Mart owes its origin to the discounting ventures of its founder, Sam Walton. Walton employed the use of various discounted stores in the promotion of increased sales. Thus, Walton opened his first discounted store in Arkansas in 1962 which represented the birth of Wal-Mart Company. The company has, thus, rapidly expanded to become one of the leading companies in the world with regard to the retail industry. Comparative Analysis of both Wal-Mart and Walgreens Both Wal-Mart and Walgreen companies have engaged in cut-throat competition practices with regard to the dominance of the drug ret ail industry. However, it is necessary to note that upon the inception of Wal-Mart in 1962, Walgreens had been in operation for over 50 years. Thus, in order to gain rapid market share and competitive advantage with regard to Walgreens, Wal-Mart had to employ strategic competitive measures. Thus, Wal-Mart employed strategy that was centered on improving livelihoods. Enhancing people’s lives, thus, formed Wal-Mart’s mission (Amendola, 2012). This was accomplished through helping people to save money. Sam, Wal-Mart’s founder, wanted to improve people’s lives by lowering the high cost of living. Through the establishment of various strategies in Wal-Mart, Sam succeeded in creating a suitable platform for

Unipart Logistics has a wide client base in departments like retail, automotive, retail, technology, defence and aerospace (Unipart Logistics, 2013c). Unipart Logistics is a part of the Unipart Group of Companies and specializes in outsourcing logistics and delivery services. The marketing consultant of the company has decided to enter into the Brazilian markets and wants to conduct a situational analysis. The situational analysis would help in the assessment of the external force which might affect the profitability of the company. An internal analysis would be conducted to understand the company’s current strategic position and check whether it is suitable for the company to enter into foreign markets like Brazil a nd further inside. Finally, the study would conclude with recommendations which would highlight on improving the current business activities and methods before entering into Brazilian markets. Marketing Environment Analysis Political, Economic, Social and Technology Analysis Political, Economic, Social and Technology (PEST) Analysis would be conducted for identifying and understanding the external threats and opportunities faced by logistics industry in Brazil. Political Presently, the corporate tax rate of Brazil is 35 percent which is very high compared to the other developing countries (KPMG, 2013). The high corporate tax rate has limited the entry of several logistics and supply chain companies into Brazil (KPMG, 2013). The corporate tax rates of a particular country helps the logistic companies to decide upon the transportation, warehouse and delivery charges for their clients (Brazil Business, 2013b). Apart from the corporate tax rate, these companies need to also consider oth er tax reformations like Contribution Incident on Liquid Profit (CILP) (15 percent) , ICMS tax (12 percent) and ISS tax ( ranges from 2 to 5 percent ) (Brazil Business, 2013b). Economic Presently, the economic situation for logistic companies is not preferable due to the very high logistic costs allocated by the government. The logistic and supply chain companies spend 8 to 10 percent of their annual GDP which is almost double compared to the average of other developed countries (Brazil Business, 2013a). Moreover, the infrastructure is unfavourable for the development of the sector because the transport matrix developed by the government is favourable only for road transportation companies. Social The success of the logistic and supply chain companies depends upon the nature of their delivery organizations to a large extent. The success of these organizations in turn depends upon the social culture and lifestyle of the individuals. If the purchasing power of the common people increa ses, then the sales will also increase automatically and vice versa. Technological The logistic and supply chain industry is usually dependent on technology used for the movement and storage of goods within an accurate time frame (Global Logistics Media, 2013). Technology has totally

Toll Fraud Schemes Essay Example for Free

Toll Fraud Schemes Essay Toll fraud is identified as the stealing of long distance call services by unknown third party hackers (Aginsky). The said call operators are after the money they can get from stealing and selling access to international calls. There are also instances that they are doing toll fraud schemes just for fun (Aginsky). It primarily uses telephone calls to gain profit in a very easy way by fabricating stories and disguising as company representatives. Three Examples of Toll Fraud Schemes (1) Toner Phoner or Voice Mail Penetration Scheme This scheme usually happens when someone receives a call from someone declaring to be from any office supply companies and offers best deals and last chance promos for you to buy their products (Rosoff, Pontell, and Tillman 38-39). Upon payment, no supplies will be delivered and if ever supplies are delivered, it is overpriced and of low quality (Rosoff, Pontell, Tillman 38-39). Once a complaint is filed against the supplier the truth will came out and the customer will be surprised to know that the one who called him/her has nor elation with the regular supplier (Aginsky). â€Å"Fraudulent companies often use threats of collection or legal action to get payment† (Aginsky). (2) Telemarketing The scam with telemarketing varies in forms. It can be in mail form or by means of phone calls solicitation of products to be donated in prominent charities only to find out that these charitable institutions are unregistered and fake (Rosoff, Pontell, and Tillman 35-41). Callers often disguise as sick or old and attempts to obtain delicate information like bank account or credit card numbers (Rosoff, Pontell, and Tillman 35-41). Another scenario of telemarketing is when business offices are called and they are asked of the brand and specifications of their products. After the call, shipments of unsolicited supplies will be received by the company and they will be charged with overblown prices. (Rosoff, Pontell, and Tillman 35-41). (3) Phone Phreaking Phone phreaking occurs by acquiring facts about the network operation of a certain telephone company in order to gain access to place unauthorized international calls (Rosoff, Pontell, and Tillman 366). Phone phreaks usually do this for personal use especially when their relatives are based abroad. It is also used for tricking telecommunication employees to gain technical information (Rosoff, Pontell, and Tillman 386-389) The effects of fraudulent schemes to consumers and businesses Victims of fraudulent schemes are not only consumers but business owners and employees as well. The reputation of businesses will be damaged and they will loose loyal customers because of wrong accusations against their company. Customer reliability is important to gain trust from customers who will patronize a particular business. Because of fraud schemes, this reliance is lost and business owners will be criticize and ridiculed   Consumers are left with the burden of paying phone bills and certain products which they did not made or purchased (Rosoff, Pontell, and Tillman).

The environmental management

The environmental management Environmental Management is a very important component of sustainable living. The interdisciplinary and transdisciplinary nature of Environmental Management enables it to solve the complex environmental problems (pollution, erosion, flooding, deforestation, desertification, just to name but a few) that essentially characterize our landscape at the local regional and global scale. To better understand these problems, the discipline draws on a wealth of expertise in both concepts and approaches from the natural or physical and social sciences to develop this interdisciplinary. This essay seeks to explore the nature of environmental management and in particular, attention is drawn on the interdisciplinary and transdisciplinarity of environmental management. The environmental problems we face today are many and varied. From pollution, erosion, flooding, deforestation, desertification, to climate change- all present themselves in very practical terms and as such environmental management is more important than ever before. However, the field has been the subject of wide criticism. For instance Bryant and Wilson (1998) criticized the field as a result of the limitations in the understanding of root causes-political, economic or cultural issues. There is no generally acceptable definition of the subject environmental management. This is partly due to its broad scope and in part of the diversity of specialism (Barrow, 1999). However, attempts have been made by several authors to define environmental management. For example, Riordan (1995); Barrow (1999); Wilson and Bryant (1997); Bryant and Geoff (2009), have all made substantial effort to define Environmental Management. Environmental management has been defined as both a process and a field of study (Wilson and Bryant 1997). In his book, Barrow (1999 p. 5) presented an overview of some definitions of Environmental Management. Like Environmental Management, definitions and interpretations of interdisciplinarity and transdisciplinarity abound in literature. For instance, Klein, 2004; Tress and Tress, 2001; Tress et al., 2005; Jones and Macdonald, 2007; Evans and Randalls, 2008; and Wesselink, 2009. In its simplest sense interdisciplinarity is an integrative research approach that transects many disciplinary boundaries with a common goal and the aim of production of new knowledge and theory (Tress et al., 2005). As a process, Environmental Management, according to (Wilson and Bryant, 1997 p.7) can be defined   Ã‚  Ã‚  Ã¢â‚¬Å"as a multi-layered process associated with the interaction of state and non-state environmental managers with the environment and with each other. Environmental Managers are those whose livelihood is primarily dependent on the application of skill in the active and self conscious, direct or indirect, manipulation of the environment with the aim of enhancing predictability in a context of social and environmental uncertainty. † While the term state will include state officials such as Department of the Environment, DoE, and Department of Environment Food and Rural Agriculture, DEFRA, just to name a few, non-state, on the other hand includes environmental NGOs, farmers, transnational corporations(TNCs), hunter-gatherers. In this light, environmental management is a process not exclusive only to large national and international environmental actors but inclusive to a range of predominantly local level environmental actors (Wilson and Bryant, 1997). On the other hand, Environmental management, as a field of study, evolved with the growing concern about environmental degradation in the late 1960s and early 1970 (Bryant and Geoff, 2009; Wilson and Bryant, 1997) after post industrialization. According to Barrow (2006: 24-26) Environmental Management as a field can be subdivided into the following: â€Å"sustainable development issues; environmental assessment, modeling, forecasting and hindcasting;corporate environmental management; pollution recognition and control; environmental economics;environmental enforcement and legislation; environment and development institutions and ethics; environmental management systems and quality issues; environmental planning and management; assessment of stakeholders involved in environmental management; environmental perceptions and education; community participation for environmental management/sustainability; institution building for environmental management/sustainable development; biodiversity conservation; natural resources management; environmental rehabilitation/restoration; environmental politics; environmental aid and institution building†. While the list is not exhaustive, partly because Environmental Management is relatively a nascent discipline (Barrow, 2006) and is still evolving, its broad scope is readily appreciated at a glance, as it tends to techno-centric problem solving approach rather than reactive approach. Table 1 highlights some distinguishing features of traditional environmental management as it were during its early evolution and at present. Referring to interdisciplinarity, the interdisciplinary nature of environmental management is more than just integration. It is essentially a modern way of thinking that involves identification, definition as well as interpretation of studies with the view of proffering practical oriented solutions to environmental problems (ORiordan, 1995). Again, Transdisciplinary studies according to Tress et al. (2005) involves the integration of both academic and non-academic participant (stakeholders) to research a common goal with the creation of new knowledge and theory. It is explicit from the definitions above that interdisciplinarity and transdisciplinarity are both integrative, in that new knowledge and theory is created. However, a distinguishing element is that transdisciplinary research combines interdisciplinarity with a participatory approach (Tress et al., 2005) Traditional Environmental Management Modern Environmental Management Largely top-down approach Bottom-up approach Management was authoritarian participatory and much more integrative Short term plan Long term plan and therefore sustainable Exploitational in approach Emphasizes stewardship rather than exploitation. Tends to be reactive Tends to be proactive and participatory Disciplinary, at best multidisciplinary Interdisciplinary, or even holistic in approach State centric Non state factors involved in the process of EM Influence of natural science discipline Shift from the natural science to social science Tress and Tress (2001) introduced a transdisciplinary landscape concept. The transdisciplinary landscape concept, according to Tress and Tress (2001) is based on five dimensions: the spatial entity, the mental entity, the temporal dimension, the nexus of nature and culture, and the systemic properties of landscape. The significance of collaboration in interdisciplinary and trandisciplinary research in the understanding of human-environment interaction cannot be overemphasized. Although environmental management takes its root from the natural science, however there seems to be a shift from the natural science to social science (Bryant and Wilson, 1998). Figure 1 as shown in the appendix depicts the profound influence from the social sciences and again, in the words of Wilsons and Bryant (1997, p 17) Environmental Management operates at the intersection of a range of disciplines and subdisciplines. From the foregoing, It is obvious that Environmental Management is increasingly becoming interdisciplinary and applying a great deal of transdisciplinarity approaches. For example, Wesselink (2008) and Potschin and Haines-Young (2005) have emphasized the importance of applying transdisciplinarity in their studies of land use planning and landscape ecology respectively.. While the environmental problems we face today are many and varied both in scope and complexity, no one discipline can effectively provide the knowledge adequate enough to fully understand nor solve them (Tress and Tress, 2001). Modern approaches of interdisciplinary and transdisciplinarity in Environmental Management can be a panacea of all local to global environmental ills. This notwithstanding, more powerful and robust tools are needed for dealing with the problems of scaling and uncertainty which are crucial in the human-environment interaction at all scale. It is the position of this essay, therefore, that while the search for a strong and robust tools continues in order to mitigate, control and prevent environmental problems, active consultation and collaboration with local communities is a necessary ingredient for sustainable solution.

Identifying Macromolecules by Means of Colour Change

Identifying Macromolecules by Means of Colour Change By Marike Coetzee B Dietetics II 1. Introduction 1.1 Aim The purpose of this lab was to observe the colour changes (due to chemical reactions) indicators had on different macromolecules in food;1 such as starch, proteins and lipids; and then to identify the macromolecules found in an Unknown solution. These known solutions contained different types of macromolecules which each reacted with at least one indicator solution in a unique way, which allowed us to identify the macromolecule based upon the presence or absence of a colour change. Water was also used as a control solution, as it showed a negative reaction with the indicator solutions.2 This experiment produced results which provided a clear understanding of the colour change that occurred when each known solution reacted with each indicator solution. When the colour changes associated with the Unknown solution were compared with those of the known solutions, it is possible to deduce which macromolecules are present in the Unknown solution 1.2 General background The four types of macromolecules (organic compounds) found in all living organisms and substances are lipids, carbohydrates, proteins, and nucleic acids. Foods and nutrients, which consist of plants, animals or derivatives thereof; are a combination of these macromolecules.3 It is important to determine which macromolecules are found in food as macromolecules play an important role in nutrition. The basis of this experiment is that the four types of macromolecules consist of different atoms and atom arrangements. Protein for example contains an NH group while carbohydrates contain a CHO group. This difference will cause the molecules to react differently with substances and enabling us to determine the compositions of different samples.4 ProteinCarbohydrate 1.3 Focussed background Negative and positive results for each indicator:1 *The intensity of the colours is an indication of the amount of the respective macromolecules found in the samples. Water, protein, starch, lipid, vitamin C and an unknown sample were each treated with the different indicators solutions (iodine, Sudan III and Biuret copper sulphate) to determine how that sample solution (and that type of macromolecule) would react with each specific indicator. The identity of the unknown solution can then be determined by comparing the reactions of the unknown solution with the reactions of the five known solutions. 2. Method and Materials 2.1 Materials/ Reagents Apparatus used: White paper 10ml test tubes Pipette Reagents: WaterAscorbic AcidIodine solution ProteinGlucoseSudan III LipidUnknownBiuret copper solution 2.2 Procedure: Set up three sets of seven clear, clean, 10ml test tubes and mark each set with the following: water, protein, starch, lipid, vitamin C and an unknown sample. Place 5 ml of each solution into each tube. Add one drop iodine to the first set of seven tubes, Sudan III to the second set and Biuret copper sulphate to the last set of tubes. Place a white paper behind the tubes so any colour change can be easily observed Record the colour changes in the table below. 3. Results 4. Discussion Interpretation of results To create a control group, the different indicator solutions was added to water and used as a colour standard for a negative result. Any colour variation from the control group means a positive result. The indicator solution that could best be used to show the presence of different starch molecules was Iodine as it turned from yellow to a dark/ purple black in the presence of starch. Sudan III is the best indicator of lipids, since this solution turned orange, which is different than the controls red colour, and also only reacts with lipids and none of the other macromolecules. To test for protein; a biuret copper sulphate solution was used, since protein reacted with the biuret copper sulphate to form a dark purple solution. This is considered a change since this solution (purple) is a different colour than the control solution (light blue). Vitamin C has two indicator solutions that can be used to determine its identity: iodine and biuret copper sulphate. The iodine indicator reacted with the vitamin C to produce a colourless solution, which can be contrasted with the yellow control, while the biuret and copper sulphate produced a yellow solution that differed from the light blue control. Broader implication of results The Iodine solution turned yellow to colourless in the presence of simple carbohydrates (starch and Vitamin C) but it turned dark purple/black when it was added to the Unknown solution. From the focussed background information, it can be deduced that the Unknown sample contained a complex carbohydrate. The Sudan III tested positive (changed from light red to orange) when added to a lipid but no colour change occurred when the indicator was added to the unknown. Therefore the unknown sample does not contain any lipids Although the Biuret and Copper solution reacted differently for each of the protein, lipid and vitamin C; the solution stayed light blue when added to the starch and unknown. This proves again that the Unknown is a carbohydrate. Conclution Due to the colour changes observed when the Unknown sample was treated with the different indicators, it can be deduced that the Unknown sample contained a complex carbohydrate, and none lipids or proteins. The unknown solution, labelled Unknown, reacted with the iodine indicator to form a purple black solution. The only known solution which reacted with iodine to form a black solution was starch. Although these colours don’t match up perfectly, they are the closest match. The difference in colour between the starch solution and the Unknown solution could be explained by a difference in concentration between the two solutions or by the difference in degree of complexity of the different starches. A factor that could have influence the difference in concentration is if the solutions weren’t both well shaken, since starch can settle out of solution. 5.

where did all the yams go? :: essays research papers fc

What About All Those Yams? After all those stories and discussions about yams, I was curious to see what exactly Nigerians eat. As an agricultural society, most of their food comes from farming. They do have meat, but yams are the main food component of their diet. Most Nigerians eat a light breakfast and have their main meal in the late afternoon (Chroness). For meats, Nigerians have goat, cow, chicken, turkey, geese, guinea fowls, pigeon, fish, shrimp, crab, and other seafood. For fruits and vegetables, they have oranges, bananas, pineapples, tangerines, carrots, watermelons, guava, melons, limes, grape fruits, mangos, apple (tinier than American apples and pink and white in color), peppers, tomatoes, onions, peas, and many other things (Chroness). Yams, cocoyams and sweet potatoes are popular in Nigeria. Ah, those yams, also called isu. The image we, as Americans, conjure up when we think of yams is not the same as Nigerian yams. These yams can grown up to 7 feet long and weigh approximately 150 pounds. They have three (3) types of yams: white, yellow, and à ¢Ã¢â€š ¬Ã‹Å"water yamsà ¢Ã¢â€š ¬Ã¢â€ž ¢ (Gourmet). There are numerous ways to prepare and serve this abundant Nigerian food staple. However, they must be cooked, otherwise they are very toxic. Plain boiled yams, either white or yellow, are peeled, sliced up, usually into pieces about 3 centimeters, and boiled in water with salt. It is accompanied with vegetable oil, palm, oil, eggs, beans, and sometimes soup (Gourmet). Another popular meal is a variation of the above using boiled yams requires pounding the yams and forming small smooth balls with the them, it is eaten with vegetables, meat or fish soup. Nigerians also fry their yams. White or yellow yams are cut up into long thin squares and fried in vegetable oil or palm oil (Lipman). This is usually eaten by itself or occasionally as a side dish. Another dish is ojojo. This dish consists of cut up water yams that are fried in vegetable oil or palm oil. This dish is also usually eaten on its own(Recipes). Asaro is white or yellow yams peeled, sliced, and diced into small cubes, then cooked with ground tomatoes, peppers, sometimes meat, other spices, and comes out reddish in color (Recipes). Ikokore is similar to asaro, but it is made with different yams. Yes, there are different forms of yams! The water yam is softer in texture and, when cooked, it usually comes out a brownish color.

In my last speech I talked about globalization and more specifically the affect of NAFTA on the Mexican corn farmers. As a result of the removal of tariffs on agricultural products, Mexico, a country once self sufficient in basic grains, today imports 95 percent of its soy, 58 percent of its rice, 49 percent of its wheat, and 40 percent of its meat. This has resulted in Mexican corn farmers being put out of business. More than 80 percent of Mexico's extreme poor live in rural areas, and more than 2 million are corn farmers. There is no way they can compete with subsidized American agribusiness. In my last speech I didn’t mention the affect of globalization on the U.S. In the U.S., a comparison between the 1930s and today tells a similar grim tale. Then, 25 percent of the population lived on the nation's 6 million farms; today, 2 million farms are home to 2 percent of the population. Small family farms have been overwhelmingly replaced by large commercial farms, with 8 percent of farms accounting for 72 percent of sales. Small family farms can’t compete with the large industrialized farms, where the only relevant objective is profit margin. While doing my research for this speech I was trying to find some type of policy that the U.S. carries for globalization, to my surprise there is no actual outlined policy. There are policies on various different topics that all fit into the globalization. I would like to concentrate on our trade policy in terms of agriculture. The World Trade Organization (WTO) Agreement on Agriculture (AOA) requires that countries open their economies to agricultural products. Due to the low or at times non existent tariffs on importing and exporting we are cutting jobs domestically and abroad. With American markets already saturated, the U.S. is aggressively pushing to open up foreign markets -- with great success. Already, one out of three acres planted in the United States produces food or fiber destined for export, and one quarter of American farm sales are now exports. Though agriculture was the incentive to lure the Third World into the WTO and other trade agreements, it has turned into the most contentious issue as the Third World is devastated by the dumping of cheap and subsidized agricultural products from the United States and the European Union. While beefing up agribusiness with agricultural subsidies (the U.

Blue Fin Restaurant

Imagine walking in the door of a lovely restaurant. Inside, the customers see Asian paintings and notice the clean restaurant with a fusion taste. Blue Fin restaurant is filled with Japanese heritage and atmosphere. Japanese speaking hosts seat the hungry customers at a table lined with a hand-stitched Asian tablecloth with candles on top. The waiter brings the menus and tea to the table, and while deciding what to order, the customers can relax to traditional Japanese house music all the way to modern day music. Before ordering, customers are tortured with the aroma of the food surrounding them. Fresh tea all around, hot soup, and delicious appetizers right from the kitchen pass by their table on the way to the mouths of other hungry customers. Deciding what to order could be the hardest task of the night. Looking around at what others have ordered doesn’t help much either: almost every dish looks good enough to eat. The menu has a variety of different Japanese dishes. With everything from Shrimp tempura to fresh Sushi, almost anyone can find something they can enjoy. The ambience of Blue Fin is that this new space has a sort of club atmosphere, with flashing lights; ambient electronic; a red, black, and white color scheme; even a cool bathroom. It may be awful lot of atmosphere crammed into a tiny storefront, but while waiting for your order you can enjoy yourself with the surroundings. The idea of giving a Japanese restaurants tears it apart from traditional sushi restaurants, it gives it a more modernistic yet a unique taste that it can target young couples or all sorts of age to come. When you walk into a restaurant you don’t want to see just a plain restaurant with dull colors, you want to be able to remember it and be able to keep the taste of it fresh in your mind. Blue Fin is an upscale restaurant that welcomes family and businesses. Usually Japanese restaurants are looked upon as a more expensive place than others, but with the quality that Blue Fin has to offer it is well worth the money. The restaurant is located in downtown Chicago the center of all attention. Around this restaurant there are many attractions including Millenium Park, train station and also by many offices including Chase Bank building. This location was chosen so that people can not only have the choice of choosing the typical Italian Bistro restaurants that Chicago is known for, but also can have a new sense of an up-scale Japanese Fusion restaurant. There will be three servers, four sushi chefs, and two assistant chefs behind the kitchen, one manager and also one bartender that would be serving only during the dinner shift.

Fddi and Cddi

C H A P T E R 8 Chapter Goals †¢ †¢ †¢ †¢ Provide background information about FDDI technology. Explain how FDDI works. Describe the differences between FDDI and Copper Distributed Data Interface (CDDI). Describe how CDDI works. Fiber Distributed Data Interface Introduction The Fiber Distributed Data Interface (FDDI) specifies a 100-Mbps token-passing, dual-ring LAN using fiber-optic cable. FDDI is frequently used as high-speed backbone technology because of its support for high bandwidth and greater distances than copper. It should be noted that relatively recently, a related copper specification, called Copper Distributed Data Interface (CDDI), has emerged to provide 100-Mbps service over copper. CDDI is the implementation of FDDI protocols over twisted-pair copper wire. This chapter focuses mainly on FDDI specifications and operations, but it also provides a high-level overview of CDDI. FDDI uses dual-ring architecture with traffic on each ring flowing in opposite directions (called counter-rotating). The dual rings consist of a primary and a secondary ring. During normal operation, the primary ring is used for data transmission, and the secondary ring remains idle. As will be discussed in detail later in this chapter, the primary purpose of the dual rings is to provide superior reliability and robustness. Figure 8-1 shows the counter-rotating primary and secondary FDDI rings. Internetworking Technologies Handbook 1-58705-001-3 8-1 Chapter 8 FDDI Transmission Media Fiber Distributed Data Interface Figure 8-1 FDDI Uses Counter-Rotating Primary and Secondary Rings Primary Secondary FDDI Concentrator WAN Standards FDDI was developed by the American National Standards Institute (ANSI) X3T9. 5 standards committee in the mid-1980s. At the time, high-speed engineering workstations were beginning to tax the bandwidth of existing local-area networks (LANs) based on Ethernet and Token Ring. A new LAN media was needed that could easily support these workstations and their new distributed applications. At the same time, network reliability had become an increasingly important issue as system managers migrated mission-critical applications from large computers to networks. FDDI was developed to fill these needs. After completing the FDDI specification, ANSI submitted FDDI to the International Organization for Standardization (ISO), which created an international version of FDDI that is completely compatible with the ANSI standard version. FDDI Transmission Media FDDI uses optical fiber as the primary transmission medium, but it also can run over copper cabling. As mentioned earlier, FDDI over copper is referred to as Copper-Distributed Data Interface (CDDI). Optical fiber has several advantages over copper media. In particular, security, reliability, and performance all are enhanced with optical fiber media because fiber does not emit electrical signals. A physical medium that does emit electrical signals (copper) can be tapped and therefore would permit unauthorized access to the data that is transiting the medium. In addition, fiber is immune to electrical interference from radio frequency interference (RFI) and electromagnetic interference (EMI). Fiber historically has supported much higher bandwidth (throughput potential) than copper, although recent technological advances have made copper capable of transmitting at 100 Mbps. Finally, FDDI allows 2 km between stations using multimode fiber, and even longer distances using a single mode. FDDI defines two types of optical fiber: single-mode and multimode. A mode is a ray of light that enters the fiber at a particular angle. Multimode fiber uses LED as the light-generating device, while single-mode fiber generally uses lasers. Internetworking Technologies Handbook 8-2 ct840801 1-58705-001-3 Chapter 8 Fiber Distributed Data Interface FDDI Specifications Multimode fiber allows multiple modes of light to propagate through the fiber. Because these modes of light enter the fiber at different angles, they will arrive at the end of the fiber at different times. This characteristic is known as modal dispersion. Modal dispersion limits the bandwidth and distances that can be accomplished using multimode fibers. For this reason, multimode fiber is generally used for connectivity within a building or a relatively geographically contained environment. Single-mode fiber allows only one mode of light to propagate through the fiber. Because only a single mode of light is used, modal dispersion is not present with single-mode fiber. Therefore, single-mode fiber is capable of delivering considerably higher performance connectivity over much larger distances, which is why it generally is used for connectivity between buildings and within environments that are more geographically dispersed. Figure 8-2 depicts single-mode fiber using a laser light source and multimode fiber using a light emitting diode (LED) light source. Figure 8-2 Light Sources Differ for Single-Mode and Multimode Fibers Laser light source Single mode Multimode LED light source ct840802 FDDI Specifications FDDI specifies the physical and media-access portions of the OSI reference model. FDDI is not actually a single specification, but it is a collection of four separate specifications, each with a specific function. Combined, these specifications have the capability to provide high-speed connectivity between upper-layer protocols such as TCP/IP and IPX, and media such as fiber-optic cabling. FDDI’s four specifications are the Media Access Control (MAC), Physical Layer Protocol (PHY), Physical-Medium Dependent (PMD), and Station Management (SMT) specifications. The MAC specification defines how the medium is accessed, including frame format, token handling, addressing, algorithms for calculating cyclic redundancy check (CRC) value, and error-recovery mechanisms. The PHY specification defines data encoding/decoding procedures, clocking requirements, and framing, among other functions. The PMD specification defines the characteristics of the transmission medium, including fiber-optic links, power levels, bit-error rates, optical components, and connectors. The SMT specification defines FDDI station configuration, ring configuration, and ring control features, including station insertion and removal, initialization, fault isolation and recovery, scheduling, and statistics collection. FDDI is similar to IEEE 802. 3 Ethernet and IEEE 802. 5 Token Ring in its relationship with the OSI model. Its primary purpose is to provide connectivity between upper OSI layers of common protocols and the media used to connect network devices. Figure 8-3 illustrates the four FDDI specifications and their relationship to each other and to the IEEE-defined Logical Link Control (LLC) sublayer. The LLC sublayer is a component of Layer 2, the MAC layer, of the OSI reference model.

FDDI defines four types of devices: single-attachment station (SAS), dual-attachment station (DAS), single-attached concentrator (SAC), and dual-attached concentrator (DAC). An SAS attaches to only one ring (the primary) through a concentrator. One of the primary advantages of connecting devices with SAS attachments is that the devices will not have any effect on the FDDI ring if they are disconnected or powered off. Concentrators will be covered in more detail in the following discussion. Each FDDI DAS has two ports, designated A and B. These ports connect the DAS to the dual FDDI ring. Therefore, each port provides a connection for both the primary and the secondary rings. As you will see in the next section, devices using DAS connections will affect the rings if they are disconnected or powered off. Figure 8-4 shows FDDI DAS A and B ports with attachments to the primary and secondary rings. Internetworking Technologies Handbook 8-4 1-58705-001-3 Chapter 8 Fiber Distributed Data Interface FDDI Fault Tolerance Figure 8-4 FDDI DAS Ports Attach to the Primary and Secondary Rings Primary Primary Port A Port B Secondary Secondary FDDI DAS An FDDI concentrator (also called a dual-attachment concentrator [DAC]) is the building block of an FDDI network. It attaches directly to both the primary and secondary rings and ensures that the failure or power-down of any SAS does not bring down the ring. This is particularly useful when PCs, or similar devices that are frequently powered on and off, connect to the ring. Figure 8-5 shows the ring attachments of an FDDI SAS, DAS, and concentrator. Figure 8-5 A Concentrator Attaches to Both the Primary and Secondary Rings FDDI Concentrator DAS SAS SAS FDDI Fault Tolerance FDDI provides a number of fault-tolerant features. In particular, FDDI’s dual-ring environment, the implementation of the optical bypass switch, and dual-homing support make FDDI a resilient media technology. ct840805 Internetworking Technologies Handbook 1-58705-001-3 ct840804 8-5 Chapter 8 FDDI Fault Tolerance Fiber Distributed Data Interface Dual Ring FDDI’s primary fault-tolerant feature is the dual ring. If a station on the dual ring fails or is powered down, or if the cable is damaged, the dual ring is automatically wrapped (doubled back onto itself) into a single ring. When the ring is wrapped, the dual-ring topology becomes a single-ring topology. Data continues to be transmitted on the FDDI ring without performance impact during the wrap condition. Figure 8-6 and Figure 8-7 illustrate the effect of a ring wrapping in FDDI. Figure 8-6 A Ring Recovers from a Station Failure by Wrapping Station 1 MAC B A Station 4 Ring wrap Ring wrap Station 2 A MAC B B MAC A A B Failed station Station 3 Internetworking Technologies Handbook 8-6 1-58705-001-3 Chapter 8 Fiber Distributed Data Interface FDDI Fault Tolerance Figure 8-7 A Ring also Wraps to Withstand a Cable Failure Station 1 MAC B A Station 4 Ring wrap Station 2 A MAC B B MAC A Failed wiring Ring wrap A B Station 3 When a single station fails, as shown in Figure 8-6, devices on either side of the failed (or powered-down) station wrap, forming a single ring. Network operation continues for the remaining stations on the ring. When a cable failure occurs, as shown in Figure 8-7, devices on either side of the cable fault wrap. Network operation continues for all stations. It should be noted that FDDI truly provides fault tolerance against a single failure only. When two or more failures occur, the FDDI ring segments into two or more independent rings that are incapable of communicating with each other. Optical Bypass Switch An optical bypass switch provides continuous dual-ring operation if a device on the dual ring fails. This is used both to prevent ring segmentation and to eliminate failed stations from the ring. The optical bypass switch performs this function using optical mirrors that pass light from the ring directly to the DAS device during normal operation. If a failure of the DAS device occurs, such as a power-off, the optical bypass switch will pass the light through itself by using internal mirrors and thereby will maintain the ring’s integrity. The benefit of this capability is that the ring will not enter a wrapped condition in case of a device failure. Figure 8-8 shows the functionality of an optical bypass switch in an FDDI network. When using the OB, you will notice a tremendous digression of your network as the packets are sent through the OB unit. Internetworking Technologies Handbook 1-58705-001-3 ct840807 MAC 8-7 Chapter 8 FDDI Fault Tolerance Fiber Distributed Data Interface Figure 8-8 The Optical Bypass Switch Uses Internal Mirrors to Maintain a Network Station 1 Station 1 B A B A Failed station Optical bypass switch â€Å"normal configuration† Station 4 A B Optical bypass switch â€Å"bypassed configuration† Ring does not wrap Station 2 A B Station 2 A B Station 4 A B A B A B Station 3 Station 3 Dual Homing Critical devices, such as routers or mainframe hosts, can use a fault-tolerant technique called dual homing to provide additional redundancy and to help guarantee operation. In dual-homing situations, the critical device is attached to two concentrators. Figure 8-9 shows a dual-homed configuration for devices such as file servers and routers. Internetworking Technologies Handbook 8-8 1-58705-001-3 Chapter 8 Fiber Distributed Data Interface FDDI Frame Format Figure 8-9 A Dual-Homed Configuration Guarantees Operation Concentrator Concentrator File servers Routers One pair of concentrator links is declared the active link; the other pair is declared passive. The passive link stays in backup mode until the primary link (or the concentrator to which it is attached) is determined to have failed. When this occurs, the passive link automatically activates. FDDI Frame Format The FDDI frame format is similar to the format of a Token Ring frame. This is one of the areas in which FDDI borrows heavily from earlier LAN technologies, such as Token Ring. FDDI frames can be as large as 4,500 bytes. Figure 8-10 shows the frame format of an FDDI data frame and token. Figure 8-10 The FDDI Frame Is Similar to That of a Token Ring Frame Data frame Preamble Start delimiter Frame control Destination address Source address ct840809 Data FCS End delimiter Frame status Token Preamble Start delimiter Frame control End delimiter FDDI Frame Fields The following descriptions summarize the FDDI data frame and token fields illustrated in Figure 8-10. Internetworking Technologies Handbook 1-58705-001-3 8-9 Chapter 8 Copper Distributed Data Interface Fiber Distributed Data Interface †¢ †¢ †¢ †¢ †¢ †¢ †¢ Preamble—Gives a unique sequence that prepares each station for an upcoming frame. Start delimiter—Indicates the beginning of a frame by employing a signaling pattern that differentiates it from the rest of the frame. Frame control—Indicates the size of the address fields and whether the frame contains asynchronous or synchronous data, among other control information. Destination address—Contains a unicast (singular), multicast (group), or broadcast (every station) address. As with Ethernet and Token Ring addresses, FDDI destination addresses are 6 bytes long. Source address—Identifies the single station that sent the frame. As with Ethernet and Token Ring addresses, FDDI source addresses are 6 bytes long. Data—Contains either information destined for an upper-layer protocol or control information. Frame check sequence (FCS)—Is filed by the source station with a calculated cyclic redundancy check value dependent on frame contents (as with Token Ring and Ethernet). The destination address recalculates the value to determine whether the frame was damaged in transit. If so, the frame is discarded. End delimiter—Contains unique symbols; cannot be data symbols that indicate the end of the frame. Frame status—Allows the source station to determine whether an error occurred; identifies whether the frame was recognized and copied by a receiving station. †¢ †¢ Copper Distributed Data Interface Copper Distributed Data Interface (CDDI) is the implementation of FDDI protocols over twisted-pair copper wire. Like FDDI, CDDI provides data rates of 100 Mbps and uses dual-ring architecture to provide redundancy. CDDI supports distances of about 100 meters from desktop to concentrator. CDDI is defined by the ANSI X3T9. 5 Committee. The CDDI standard is officially named the Twisted-Pair Physical Medium-Dependent (TP-PMD) standard. It is also referred to as the Twisted-Pair Distributed Data Interface (TP-DDI), consistent with the term Fiber Distributed Data Interface (FDDI). CDDI is consistent with the physical and media-access control layers defined by the ANSI standard. The ANSI standard recognizes only two types of cables for CDDI: shielded twisted pair (STP) and unshielded twisted pair (UTP). STP cabling has 150-ohm impedance and adheres to EIA/TIA 568 (IBM Type 1) specifications. UTP is data-grade cabling (Category 5) consisting of four unshielded pairs using tight-pair twists and specially developed insulating polymers in plastic jackets adhering to EIA/TIA 568B specifications. Figure 8-11 illustrates the CDDI TP-PMD specification in relation to the remaining FDDI specifications. Internetworking Technologies Handbook 8-10 1-58705-001-3 Chapter 8 Fiber Distributed Data Interface Summary Figure 8-11 CDDI TP-PMD and FDDI Specifications Adhere to Different Standards FDDI Media Access Control (MAC) FDDI physical layer (PHY) FDDI Station Management (SMT) Twisted-pair wire PMD Single-mode fiber PMD Multimode fiber PMD Specification for CDDI Summary The Fiber Distributed Data Interface (FDDI) specifies a 100-Mbps token-passing, dual-ring LAN architecture using fiber-optic cable. FDDI is frequently implemented as a high-speed backbone technology because of its support for high bandwidth and greater distances than copper. Review Questions Q—What are the benefits of using FDDI instead of CDDI? A—Longer distance, no RFI, no EFI. Q—What role does the DAC play in the FDDI network? A—The concentrator is a dual-attachment station device and ensures that when single-attachment station devices—such as PCs—are turned off, they do not interrupt the network ring.

 Learning experience : How someone could become afraid of the dentist Essay

There are many reasons someone could become afraid of going to the dentist. Majority of people become afraid of the dentist due to a bad experience they have encountered. Just to name a few: the dentist was a painful experience, the dentist made your teeth worse, etc. In my own experience, I was afraid of the dentist because of a horror film. At nine years old, my sister let me watch a horror movie called the dentist. It was about a mentally unstable dentist who tortures some of his patients. A year or so after I had seen this movie my mother surprisingly brings me to the dentist for the first time. As we were walking into the dental office I cannot help but to tremble and burst into tears because I could not stop thinking of the dentist from the movie. That day I only had my teeth cleaned and x-rays. My mother scheduled me to have cavities filled in the next month. My brother and sister taunted me by telling me scary stories about trips to the dental so the day I was scheduled to ge t my cavities filled. I decided to run away to the library and stayed there until closing. My mother had to reschedule my appointment for the following week. That time she made sure I went. Conditioning My conditioned stimuli were triggered by walking into the dental office my condition response was crying and trembling because I was afraid that the dentist would torture me, therefore, my unconditional stimuli were watching the dentist torture and kill his patients. My unconditional response was to be scared of all dentists and run away for a few hours so I would miss my appointment. Operant Learning My training experience could have occurred through operant conditioning since I did not quite understand that what you watch on television might not be real. If my mother had not forced me to go inside the dental office would still be petrified and I would have never gone to the dentist; my teeth would be in bad shape. Observational Learning The learned experience could occur through observational learning if my mom or anyone else I knew were scared of the dentist that would have also made  me afraid of the dentist because I would be observing their response to the dental. Another reason I might have been scared of going to the dentist was hearing my brother and sister tell me scary stories about how the dentist pulls your teeth out and you can feel every slight of pain. Reinforcement My mother dragging me into the dental office is where reinforcement was experienced. When my mother gave me no other choice except to get my teeth clean I then realize that the dentist was not so bad.

An Introduction to the Im Profession and Ethics Paper

De La Salle University – Manila An Introduction to the IM Profession and Ethics Paper Presented to The Faculty of the College of Computer Studies De La University – Manila In Partial Fulfillment Of the Requirements for the Degree of Bachelor of Science of Information Systems By: Changcoco, Amos Dimla, Ysabel Nicole Ramchand, Pavan Tanchuling, Bianca Denise Tibayan, Jan Michael 1. 0 COMPUTER AND INTERNET CRIME 1. 1 Types of Exploits 1. 1. 1Virus It is a malicious code that is attached to a file or executable program that can hack the files of the victim’s computer and reformat, delete or modify the files.The virus is executed only when the file that contains the virus is opened or if the program with the virus is executed as well. It leaves infections as it travels from one computer to another. The spread of the virus relies on the users whenever users would use removable media devices, download or through e-mails. An example of a computer virus would be the Pikac hu virus which was the first computer virus directed to children. It was said that the virus started on June 28, 2000 from Asia or the Pacific Ocean region.The virus was an email titled, â€Å"Pikachu Pokemon† with the message, â€Å"Pikachu is your friend. † The email contained the image of the cartoon character, ‘Pikachu’ from the TV series Pokemon, with the message, â€Å"Between millions of people around the world I found you. Don’t forget to remember this day every time MY FRIEND. † The Pikachu virus infected only a few companies in the United States through Microsoft Outlook email attachments or through Microsoft’s Internet Explorer browser.The reason why only a few companies were harmed and why the virus was not as viral is that the virus was not coded properly and would ask the user if the virus can delete the files in the user. 1. 1. 2Worm A worm is a malicious code that is used for bringing down the computer system. A worm do es not infect files, however, it monopolies the computer’s CPU and operating system and is capable of deleting data and programs. It infects a computer by finding vulnerability in an application or operating system. A worm is self-replicating and uses a network to replicate itself to other computer.It does not rely on human interaction for spreading to other computers. An example would be the Morris Worm or also known as the Great Worm. Created by a Cornell University student named Robert Tappan Morris in the year 1968, the Morris Worm consisted of 99 lines of code. Robert Morris wanted to know how big the Internet was and made the worm to find the answer. It is noted that the creator did not have malicious intent in making this worm; however, the worm infected immense amounts of stability problems that made many systems unusable.The damage was over 6,000 infected UNIX machines which cost between $10,000,000 and $100,000,000. This example is an ethical dilemma because the cre ator did not have evil intentions in making the worm but did have bad effects on most people in America. This dilemma would be ethical based on the psychological egoism theory because Robert Morris acted on his selfish motive whether he should or not, which made him moral. Based on the hedonism theory, it was ethical of Morris because he was only doing his duty without knowing that his actions would bring upon negative effects. 1. 1. 3Trojan HorseNamed after the Trojan horse from Troy which was used to infiltrate the enemy’s territory through a disguise, the Trojan horse is disguised as something else (such as a program or file) but is actually a malicious code or may contain malicious code. Similar to viruses, a Trojan horse is executed when the file with the virus is opened or the program with the malicious code is executed also. A Trojan horse can do from light damages such as changing the desktop and the like, to threatening damage, such as deleting files, stealing data, or activating and spreading other malware, to the victim’s software.Trojan horses are also used to create a ‘back door’ in the operating system so that the hackers can access the system. However, the Trojan horse cannot duplicate itself nor it can self-replicate. It would need the user to spread to other computers. An example of a Trojan horse would be from the pirated version of Apple’s suite of software, iWork. iServices was the Trojan horse part of the pirated version of iWork, which would signal the hackers that the Mac is infected and the hacker has access to the system.This is an ethical dilemma because the people who buy pirated software such as the iWork do not know that there is a Trojan horse in the software. It was unethical of the sellers to place a Trojan horse in the software without the consent of their customers’ because deontology theory states that it was not the duty of the vendors to hack into the systems of their customers in th e first place. Another reason why it was unethical because of the theory of altruism because the interest of others was not thought about since many people will suffer due to the actions of the vendors.This is another reason why it is unethical, because of the utilitarianism, which is consequences-based. Lastly, the social contract theory states that the actions of the vendors were unethical because it is against the law to hack and infiltrate private property. Logic bomb is a type of Trojan horse that is triggered only by a series of specific events such as a specific sequence of keystrokes or a change in a file. 1. 1. 4Botnets A botnet is a network of infected computers that are controlled by bots.Named after the word ‘robot’, a bot is a type of malware that allows an attacker to take control of an affected computer. Criminal can take over the controlled computer such as sending out spam, spread viruses, attack computer and can even cause crime and fraud, without the owner knowing it. Bots are also called computer zombie because the computer has no control over its actions since hackers are in charge of its actions. 1. 1. 5Distributed Denial-Of-Service Attacks (DDoS Attacks) A Distributed Denial-of-Service Attack is when a malicious hacker controls computers through the Internet.It is an attempt in preventing the computer owner to use network resource or machine. It is composed of one or more people trying to disenable a certain host from being connected to the Internet. 1. 1. 6Rootkits The name rootkit comes from the two words ‘root’, which pertains to the point it attacks, which would be the administrator or the source or the root, and ‘kit’ because of the set of programs. A rootkit is a set of programs that enables its user to gain administrator level access to a computer without the user’s consent or knowledge.The owner of the rootkit is capable of executing files and changing system configurations on the tar get machine, as well as accessing log files or monitoring activity to covertly spy on the user's computer usage. It is hard to detect if a computer system has a rootkit malware. 1. 1. 7Spam E-mail spam is when e-mail systems send unsolicited e-mail to large numbers of people. Spam mostly comes off as cheap advertisements of strange products such as pornography, ‘get-rich-quick’ schemes and the like. Spam can also be used to deliver harmful worms or other malware. . 1. 8Phishing Phishing is an attempt to steal personal identity data by tricking users into entering information on a counterfeit Web site. 1. 2Types of Perpetrators 1. 2. 1Hackers and Crackers Hackers are people who test the limits of the system, find the â€Å"holes†, and check which data they could access. The knowledge that they get is actually obtainable in various media, usually the internet. They are not usually considered bad; but due to many of them who used such knowledge to cause harm to syst ems, the term became negative.A more appropriate term for these kinds of people is actually called crackers. 1. 2. 2 Malicious Insiders Malicious insiders are people who obtain goods, services, or property through deception or trickery, also known as fraud. In other words they lie to gain. 1. 2. 3 Industrial Spies Industrial spies are people who illegally obtain information from competitors for the benefit of their sponsor. The act is called industrial espionage and the opposite which is to obtain information legally is called competitive intelligence.In 1993, Opel accused the rival Volkswagen of industrial espionage after the former’s chief of production and seven executives moved to the latter company due to missing documents. (Julian, 2011) 1. 2. 4 Cybercriminals These perpetrators hack to the company’s system and will do anything with the information just to gain money. One of the most famous hackers of the world is Albert Gonzalez, who used hacking to steal and re sell millions of card and ATM numbers in a span of three years. He did this by attacking many systems which would eventually give him the information needed to steal the card numbers. Verini, 2010) Albert Gonzalez is in ethical dilemma because he used his skills to steal the information for money. Based on the deontological theory, it’s unethical because it is not the duty of hackers to steal information. Based on hedonism under the utilitarian theory, it is ethical because he found pleasure from the act. Social contract theory, however, makes this act unethical, and so does virtue theory. 1. 2. 5 Hacktivists and Cyberterrorists Hacktivists, combining the words â€Å"hacking† and â€Å"activist†, are people who hack to promote political ideology.Cyberterrorists attack to get the attention of the government as part of their political objectives. Anonymous is one of the most famous hacktivist groups due to their appearance on various media in which members appear wearing the Guy Fawkes mask. Their advocacy is to oppose the Internet censorship and surveillance, government corruption and homophobia. This is why they attacked several government sites. (Katich, 2013) The ethical dilemma the group faces is that they use hacking skills to infiltrate the systems yet they belong to the side of the people as their objective is to make the government hear their voice.This is ethical based on deontology because it is their duty to make the government listen to them their voice. This is also ethical based on the altruistic approach as more will benefit from their act. However, social contract theory states that it is unethical since this act has violated the law. 1. 3Laws for Prosecuting Computer Attacks 1. 3. 1Electronic Commerce Act of 2000 (RA 8792) 1. 3. 1. 1E-Commerce in Society The process of buying and selling goods electronically by consumers and from company to company through computerized business transactions.This act has the purpose of prote cting those who pursue business in electronic means through multiple communication networks through the Internet. 1. 3. 1. 2 Elements in the Law Electronic data messages – these are generally the information that is in every transaction of the business. Electronic document – these are the type of information specified with text, symbols, or other modes of written expression yet similar in nature with the electronic data messages. Electronic Signature – these are any distinctive marks that approve a transaction which are done by a person or an entity using electronic means. . 3. 1. 3Relation to other Laws Such laws that are affected with this are the Intellectual Property Rights, Copyrights Protection. These laws give protection to the parties involved in any business activities through electronic means. Fraud is also related as the government can charge you when you make accept payment illegally by disguising your site as a reliable option for payment. 1. 3. 1. 4 CASE in E-Commerce Censorship is very an essential tool to distinguish the moralities of websites and the cooperation of companies to acknowledge said moralities.In China, Google's operations created a storm of criticism when the company agreed to comply with the government's wishes and censor pro-democracy and other websites. In 2010, Google relocated its Chinese operations to Hong Kong, putting it outside China's censorship regime. Supporters of the decision say Google shouldn't cooperate with China's repressive policies, while critics say Google's withdrawal cut off millions of Chinese citizens from the company's services and weakens its presence in one of the world's largest markets. This case has very evident ethical issues including the move of Google to relocate its operations to Hong Kong.This made the jurisdiction of China’s censorship policy not reachable so that they can use their assets more freely. These however made the citizens of China that is inside the jur isdiction of the censorship policy long for their beneficial search engine. If seen in Google’s benefits this is a rather good trade for them to maximize the use of their services in a commercial area such as Hong Kong yet they could’ve served the citizens so they can keep up their reputation of improving life in the world and be consistent of the famous line â€Å"Don’t be evil†.I generally disagree with their decision to relocate as they could’ve followed the updated utilitarianism and give their services to those who would need them the most. Still they acted the ethical egoism to censor pro – democracy sites which are morally good to their perspective. 1. 3. 1. 5Another Example Including Google Google gathers incredible amounts of data on people who use its search engine. As of 2011, the company's website states that although it stores records of your searches as a tool to improve corporate efficiency, it renders them anonymous after nin e months and deletes cookies used to track visitors after two years.Governments could use Google's information to investigate individuals visiting particular websites, however, and Google Earth's photo collection also has raised privacy questions: In 2008, a couple sued on the grounds the online photos of their home violated their privacy, but a judge threw out the lawsuit the next year. This case is provides insight to how Google can be of every use to our society as they can help the government catch fugitives, suspects and criminals with their records of the searches of the every person using their search engines yet this leaves them to violate certain privacy issues when they abuse that kind of power.The lawsuit of the couple may be dismissed by a judge but their lawsuit are supported by ethical theories namely the rights – based theories which states that there are social contracts that should be acknowledged and that includes their right for privacy. They may be legal t o store records such as the photo from their Google Earth but they should have to limit their power to exercise their duty as they are also supported by the duty – based theories due to their daily or continual task of improving corporate efficiency as well as giving us access to unlimited knowledge. 1. 3. 2 Cybercrime Prevention Act of 2012 (RA 10175) 1. . 3. 1 Preliminary Provisions 1. 3. 3. 2. 1. 1 Brief History of RA 10175 Cybercrime Prevention Act of 2012 or also known as Republic Act No. 10175 was approved on September 12, 2012. This is first law in the Philippines which specifically criminalizes computer-related crimes. The Cybercrime Prevention Act in its current form is the product of House Bill No. 5808, authored by Representative Susan Tap-Sulit of the second district of Tarlac and 36 other co-authors. The final version of the Act was later signed into law by President Benigno Aquino III on September 12, 2012. 1. 3. 2. 1. 1 Declaration of PolicyThe main objective o f this Act is to protect the people from cybercrimes and also from the harmful effects associated with it. The state also aims to recognize the vital roles of information and communications industries in the country. The state also recognizes the need to protect and safeguard the citizens of the state, and also to protect the integrity of computers and its users. The state also wants to recognize the importance of providing an environment conducive to the development acceleration, and rational application and exploitation of information and communications technology. . 3. 3. 2. 1 General Provisions 1. 3. 3. 2. 2. 2. 1 Punishable Acts In this Act, there are 10 punishable acts indicated in the bill, and those punishable acts each have penalties that are associated. In the next sentences, the punishable acts will be discussed briefly. Offenses against the confidentiality, integrity, and availability of computer data and systems: A. Illegal Access – accessing a computer or a part of a computer without any right B.Illegal Interception – the interception made by the use of any technical device without any right of non-public transmission of datum to or from any computer system including electromagnetic emissions from a computer system carrying such data C. Data Interference – the intentional or any reckless alteration, damaging, deletion or deterioration of computer data, electronic document, or electronic data message, without any right including the transmission or transferring viruses into a system. One example is the ILOVEYOU message transmitted through electronic mail way back in the year 2000.D. System Interference – the intentional or any reckless hindering or interference with a functioning computer system, or a computer network by inputting, transmitting, damaging, deleting, deteriorating, altering, or supressing computer data or computer program without any right or authority in doing so. E. Misuse of Devices – the use of any material without any right of it. Acts like producing, manufacturing, selling, and distribution. F. Cyber-squatting – the simplest way is identity theft, using another individual’s identity to gain profit or scam other people in the internet.G. Computer-related Forgery – the illegal use of a computer into copying one’s work, and gaining illegal access to a computer to copy the content of a system or database. H. Computer-related Fraud – the unauthorized input, alteration, or deletion of computer data or program or interference in the functioning of a computer system. I. Computer-related Identity Theft – the intentional acquisition, use, transfer, or possession of any identifying information belonging to another person, whether natural of juridical. Under these are Cybersex and Child Pornography. J.Libel –    defined as a public and malicious imputation of a crime, or of a vice or defect, real or imaginary, or any acts, omission , condition, status or circumstance tending to discredit or cause the dishonour or contempt of a natural or juridical person committed through a computer system or any other similar means which may be devised in the future. The above stated are the punishable acts by the law enforced and written in the bill, and these acts have corresponding penalties if have been proven to the court. The penalties include: imprisonment or a fine of at least two hundred thousand pesos (Php. 00,000. 00) up to a maximum amount commensurate to the damage incurred or both. Prison mayor is equivalent to imprisonment from 6 years and one day to twelve years. 1. 3. 3 Ethical/ Moral Dilemmas 1. 3. 4. 2 Situation A 16-year old male named â€Å"Josh Evans† was registered on the account used for bullying messages to a girl named Megan Mier. Lori Drew, the mother of Sarah, a former friend Mier, later admitted creating the MySpace account. She was aided by Sarah and Ashley Grills, an 18-year-old employee of the elder Drew.The senior Drew and several others ran the fake account, with an aim to get information about Megan and use that information against her and also for her to be humiliated. This caused spreading gossips about Megan, and thus creating a traumatic experience not only for her but also to her family. 1. 3. 4. 3 Analysing using the Four Major Ethical Theories A. Duty-based Theory According to the Duty-based theory, an act is considered ethical if it has good intentions. Given the situation, I can clearly state that it is not an ethical thing to do. Creating or spreading false rumours is not even close to be called as a good intention.Also, gathering information about a certain person is not ethical if it will be used against or be held against to a person. Using the Duty-Based Theory, I can clearly state that the situation of gathering information of Megan is not ethical because it does not serve a good intention. B. Utilitarianism According to the Utilitarianism Theory an act is only to be considered ethical if it produces desirable consequences or outcomes. The outcome of the situation stated earlier is that the experience Megan was traumatic not only for herself, but it also affected her family.Just by looking at this outcome, we can say that it is not also considered ethical in this theory, because of the outcomes that the actions of the group had caused not only their target but also the relationship of other people to Megan. C. Social Contract Theory According to the social contract theory an act is considered ethical if the act does not violate any rules or laws; according to the Civil Code of the Philippines: Persons and Family Relations, under Chapter 2 which is Human Relations the Articles 19, 20 and 21 discusses the different rights a person possesses and how a person should exercise his or her rights.Chapter 2 Article 19 presents the basic principles that are to be observed for the rightful relationship between human beings and the stab ility of the social order. Chapter 2 Article 20 presents that you are liable for any damage that you have caused to another person, whether wilfully or negligently. Chapter 2 Article 26 presents that right must never abused, the moment that it is abused, the moment rights are abused they ceased to right. D. Virtue According to the Virtue theory, the action that is considered to be ethical is when the action is came from a good moral principle.Looking to the situation, it is not an ethical thing to do because it does only harm the person involved but also the moral principles of the suspect is to be questioned. 1. 3 Trustworthy Computing 1. 4. 1 Microsoft’s 4 Pillars of trustworthy Computing The 4 Pillars of trustworthy computing help identify the key elements in computing especially in an organization with numerous employees to manage. Guidance is a key to help implement a good and stable system such as how the pillars guide not just Microsoft employees but users alike. 1. 4. . 1 Security Creation of a trust worthy environment for a safe computing environment 1. 4. 2. 2 Privacy The protection and confidentiality of design, development and testing in any organization is essential as to be part of the competitive market today. 1. 4. 2. 3 Reliability Working as expected or promised by the developers and their entity 1. 4. 2. 4 Business Integrity Being responsible and transparent in you duties and expectation as part of a work force that strives to be excellent a mistake is bound to happen.Admitting a mistake is the 1st step to a growing process of learning new things to come. 1. 4. 2 Risk Assessment It is the process of assessing security related risks to an organization’s computers and networks from both internal and external (Reynolds, 2011) A risk assessment is a process to identify potential hazards and analyse what could happen if a hazard occurs. (Federal Emergency Management Agency, 2013) The assessment would assure the IT security team that they will be ready when an attack comes because of the determined risk assessment they perform. 1. 4. 1 General Security Risk Assessment ProcessStep 1: Identify IT assets and prioritize ones that are of most importance Step 2: Identify the threats/risks that could occur Step 3: Assess the likelihood of threats Step 4: Determine the impact of each threat, how large to small is the impact if affected Step 5: Determine how each threat can be prevented/blocked Step 6: Which is the most effective prevention method Step 7: Perform cost benefit analysis before taking any action Step 8: Make the decision to implement or not to implement the decided risk prevention found through thorough research and development 1. 4. 3 Establishing a security policyDefines an organization’s security requirements, as well as controls and sanctions needed to meet those requirements. (Reynolds, 2011) A good security policy can possibly improve and provide a smooth flow of operations within an organizati on. NIST (National Institute of Standards and Technology) is a non-regulatory federal agency within the US department of commerce. The computer security division creates security standards for organizations to implement in their own system. 1. 4. 4 Educating the Employees, Contractor and Part-Time Workers Surveys show that most security problems come from negligence and unawareness of the security policies.Teaching good security practices like not giving out your passwords, making sure you do not meddle in different departments. Knowing the Dos and DONTs of everyday computing will help guide any workplace and direct them to the good ways of being a good user. 1. 4. 5 Threat Prevention The key to a threat prevention system are layers of security systems that challenge the perpetrator to hack into the system. Firewall – stands guard between an organization’s internal network and the internet Intrusion Prevention Systems – prevents an attack by blocking viruses, ma lformed packets and other threats from getting into a protected network.Antivirus software – should be installed on each user’s personal computer to scan a computer’s disk drives and memory regularly for viruses. User accounts that remain active after employees leave cause an uncertain threat to the company, IT staff must promptly delete and make sure to wipe out all the privileges of the former employee. The US-CERT (United States Computer Emergency Network Team) and SANS(SysAdmin, Audit, Network,System) Institute – regularly update a summary of the most frequent and high impact threats to a computer system specifically viruses and worms. . 4. 6 Security Audit An important prevention tool that evaluates whether an organization has a good security policy and if it is being followed. An example would be a requirement to change passwords every week or month with this in place a security for companies are much more protected compared to others without this r equirement. Basically to test, check and review the system’s security and look for loop holes and easy targets. 1. 4. 7 Detection The preventive measures made for a computer system is not always enough to protect important data.Intrusion detection system – is a software/hardware that monitors system and network resources, notifies a system admin when an intrusion occurs Knowledge based intrusion system – contains information about attacks and system vulnerabilities, then trigger an alarm (ex. Repeated login, repeated data events) Behaviour based intrusion system – compares users system behaviour with an admin created model that detects when a user is not following the required model, this would trigger an alarm. (Example: Unusual activity with an account in the HR department accessing the IT department’s data. 1. 4. 8 ResponseAn organization should be prepared for the worst, like a system attack that stops all operations and steals data from the co mpany. The top priority during an attack is not to catch the perpetrator but to regain control and save what is left. Who needs to be informed? And who not to notify? Reputation and credibility is at stake in any security breach. A company should document all details of a security breach and be able to review it after to assess and further study. Eradication of the damaged/breached information is essential but before everything a log is required to keep track 1. . 9 Ethical Moral Dilemmas You are a member of a large IT security support group of a large manufacturing company. You have been awakened late at night and informed that someone has defaced your organization’s website and also attempted to gain access to computer files containing a new product under development. What are your next steps? How much time would you spend tracking down the hacker? -Deontological 1. 5 References * (1999, 10). Electronic Commerce. StudyMode. com.
