Essay on Fossil Fuel Leads to Pollution - 560 Words

INTRODUCTION With the increase in population, there has been consistent demand in every arena for fuel. Human life is largely dependent on material things. These material things are produced and transported with the help of fuel driven mediums, but fuel is largely amassed in very few countries of the world especially middle- East countries. With the growth of the economy and consumption, the governments of many countries of the world are striving hard to find an alternative to the fossil fuel which is slow gradually depleting .Moreover, the fossil fuel leads to pollution and bad effects on human health. Keeping this into mind, bio-diesel would be natural choice for countries largely dependent on import so as to utilize the natural†¦show more content†¦Waste cooking oil (WCO), which is cheaper than edible vegetable oil, is a promising alternative to edible vegetable oil (6). Waste cooking oil and animal oils set forth significant disposal problems in many parts of the world. This environmentally-threatening problem could be turned into all the economical, waste management and environmental benefit by properly using and management of waste cooking oil as a fuel replacement. Many developed countries have set policies that punish the disposal of waste cooking oil into waste drainage (7, 8). The Energy Information Administration (EIA) in the United States (USA) estimated that around 100 million gallons of waste cooking oil are produced per day in the USA, where about 9 pounds of waste cooking oil(WCO) are generated per person per year [9]. The estimated amount of waste cooking oil collected in Europe is about 0.49 - 0.7 million gallons/day [10]. Waste cooking oil, as an alternative feed-stock for bio-diesel, was studied with different aspects such as optimization using supercritical methanol (SCM) trans-esterification, process design and technological assessment, fuel property analysis and cost estimation approaches [11-13].In this work, we have carried ou t experiments for the bio-diesel production from waste cooking oil(WCO) using conventional trans-esterificationShow MoreRelated Environmental Impacts of Fossil Fuel Use Essay606 Words   |  3 PagesEnvironmental Impacts of Fossil Fuel Use One of the main issues involved with fossil fuels are the environmental impacts that occur from their use.

Social Security And Economic Security - 1311 Words

In 2033 a retiree with the average Social Security benefits of $1,294 will only receive 77% of this number or $996. This average retiree pays the average monthly costs for a single adult in Grand Rapids, Michigan of $1,323. This shows Social Security benefits today are sinking below the amount necessary to live. In the case the benefits are cut further, living on benefits will be impossible. This stays true to the 20% of retirees who rely on Social Security for all of their income. To make a truly accurate evaluation of Social Security one must look at the past which is why the following paragraphs will cover the programs history, its costs, and finally possible solutions to improve the program. History The idea for Social Security began when the Great Depression was at a climax, leaving retirees in intense poverty. One of the ways that President Roosevelt helped to combat this great poverty is by creating the Committee of Economic Security (CES), to study the need for an economic security system that would provide income for the disabled and elderly. In January 1935, the committee came to the President with a report summarizing a plan for a national program of economic security. On August 14, 1935 The Economic Security Act, today known as the Social Security Act, was passed by Congress and signed by Roosevelt (King). Over time, amendments were added to the Act. One of the most notable of these were added in 1983 under President Ronald Reagan.

The US Constitution

The book by O’Connor and Sabato (2011) is valuable, and deserves special attention. Its second chapter examined the US Constitution. The US Constitution is the product of many years American political, economical, religious, and social experience. Following O’Connor and Sabato’s book (2011), one may see that this document cannot be changed in an easy way.Advertising We will write a custom essay sample on The US Constitution specifically for you for only $16.05 $11/page Learn More From colonies to the United States, the country had passed a long challengeable way. Only the best juridical practices stroke roots on the abundant US land. The ideas that resulted in the creation of this legal document addressed the problems and demands of a changing nation (O’Connor and Sabato 30). Thus, the US Constitution has gathered those laws and legal norms that reflected the country’s historical experience. The authors’ book (20 11) describes key events that led to American independence. These events are connected with the swift development of the thirteen colonies, intense foreign policy, and the Civil War. However, the book presented Boston Massacre of 1770 as one of the most notable events that led to the independence. The incident that happened in Boston (the encounter of the American citizens, disappointed with unfair tax policy with the British authorities) resulted in the removal of the British military from the town. Six years later, on July 4, 1776, the Americans declared independence: the Declaration of Independence was adopted by the Second Continental Congress (O’Connor and Sabato 33). Since that time, the US Constitution became the supreme law that cannot be broken with impunity by each American citizen. The adoption of the Constitution was accompanied with participation of numerous notable individuals: George Washington (in 1789, he became the first US President), John Adams, James Madi son, and others. The book (2011) says that such notable figure as Benjamin Franklin signed the most essential US document of all times. He is believed to be the founding father of the US Constitution (O’Connor Sabato 36). When the American Revolution was over, in 1776, the country faced peace and legal status. O’Connor and Sabato (2011) gave the following piece of evidence: â€Å"after the Declaration was signed and transmitted to the king, the Revolutionary War was fought with a greater vengeance† (O’Connor and Sabato 38). Undoubtedly, 1776 was the extremely important year for the country’s history. The Articles of Confederation became the first written constitution of the US Government (however, the final variant was adopted only in 1789). At the same time, the period after the adoption of the Constitution was extremely difficult from political and economic points of view. The laws on trade and taxation were rather painful because the national g overnment did not have any funds to pay the army, farmers, civil services, etc.Advertising Looking for essay on government?

The authors of the book (2011) believe that the issue of slavery was one of the most important issues in the US legislature. Slavery was officially abolished only in the middle of XIX century (O’Connor and Sabato 43). In general, the US Constitution reveals all kinds of state laws, separation of powers in the country, rights of its citizens, and many other crucial points that reflect the legal norms of the US. According to the book, such documents as Bill of Rights, twenty seven successfully adopted amendments, and even the Federalist Papers of the 80s of XVIII century that protect the constitutional principles in the name of all Americans influenced the modern face of the US Constitution (O’Connor and Sabato 54). Overall, the second chapter of the author’s book (2011) concerns the most significant US document resulted from the immortal events that led to the independence of the American nation.

Strengths and Weaknesses of Mills Paper Company

Strengths and Weaknesses of Mills Paper Company Strengths One of the strengths of the company’s appraisal system is the motivation and encouragement effect it has on employees. Since the objectives to be achieved are set prior to beginning of the employment, the employee is able to use them as a driving force while doing his job.Advertising We will write a custom case study sample on Strengths and Weaknesses of Mills Paper Company specifically for you for only $16.05 $11/page Learn More Thus, the strength of the method is manifested by the fact that employees are motivated with the knowledge that they will be rewarded if they achieve the set goals. This also is an advantage to the company since in the long term it will end up achieving its targets and goals (Kantola, Armstrong Conley, 2003). The appraisal method applied by Mills Company also aids the company to identify under performers and eliminate them. An employee like Carpenter who is always showed such poor performance might not have been id entified had it not been for the appraisal method. With the appraisal method, the company was able to know that Carpenter was not achieving the objectives set for him. This is an advantage to both the company and the employee since any possible losses by the company are minimized. On the other hand, the employee is able to note his or her weak points and find ways of improving on them (Smither, 1998). The appraisal method also facilitates employee growth and development. The Mills Company sets and outlines the expectations and objectives of positions into an agreement before commencement of employment. This can be a growth and development factor as it helps employees strive to reach their full potential. This is a positive implication for both the employee and employer since the former develops professionally while the latter succeeds in its general plan and objectives. Weaknesses In my opinion, one of the main weaknesses the approach has is discouragement of employees. While some o ther employees might be encouraged to work more and more to achieve their goals, others like Carpenter might just end up being discouraged due the unpleasant experience of having to be supervised always and being forced to work hard to achieve set objectives. This is due to the fact that some employees just like dong their job at their own peace and pleasure, which is very harmful to the company’s performance. Discouragement can also be very harmful to the company because with discouraged employees the company is sure to have poor performance, just like the case in Mills Company.Advertising Looking for case study on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More In my opinion, the company’s approach might also have created a stressful environment for some of the employees, like Carpenter. With every time being reminded that he still wasn’t improving in his work and having a negative report being produced about him every time and again might also have contributed to his poor performance. Mill Company’s approach is subject to biasness to the fact that it is based on human assessment. Take for example Carpenter’s supervisors, Henry and Crane. The two, with no other consultation, prepared all Carpenter’s reports and assessments. Though not necessary, the supervisors might just have been biased towards Carpenter. This is a very serious weakness of the system since it can lead to lay off innocent employees. The approach is also time consuming and tedious, a feature that reduces its effectiveness. Take for example when Carpenter was being recruited in the company. A lot of time was spent while Carpenter and his supervisor then, Henry Castagnera, agreed on the objectives and performance metrics of Carpenter’s position. When carpenter was demoted to a lower position, still more time was spent while forming his new objectives and performance standard s. A lot of time is also required to assess the employee’s performance and write down his report. This can also be very costly to the company due to the many meetings that have to be held to assess the employee’s performance (Aguinis, 2012). Yes I do agree with Lance Amato’s observation that carpenter should have terminated earlier. This is because according to the record, carpenter never made any improvement since he joined the company. He was just so poor in his work. Note that not even once did he get a positive remark from his supervisors. In my opinion, it was just out of pity that the company continued employing him while he was generating no good service to the company. This is because though pardoned many times and not terminated, Carpenter still made no improvement. In my opinion, since the company was keeping all his records, it should have studied his performance from the start and noted how his graph was moving. After noting that it was just a fallin g graph, Carpenter should have been given just one opportunity to make an improvement failure of which he should have been terminated immediately. Probably had he been dismissed earlier the company could have been saved from experiencing some losses and poor performance, though we are not told that such occurred (Smither, 1998).Advertising We will write a custom case study sample on Strengths and Weaknesses of Mills Paper Company specifically for you for only $16.05 $11/page Learn More I think that Carpenter will not prevail in his charges against Mills. This is because the charges that he filed are null, void, and do not hold according to the legislation relevant for performance appraisals (Aguinis, 2012). To begin with, he claims unfair performance appraisal. This is not true since Mills appraisal was formulated according to the Civil Rights Act of 1991, which states that proper appraisals should be documented, and there should be a consistent application of performance standards. His claim of age discrimination will also not succeed because Carpenter was not discriminated by Mills in any way. The Age Discrimination Employment Act states that for this claim to succeed, an employee must have been discriminated because of his/her age with respect to any term of employment. Such include, hiring, firing promotion, layoff, and benefits among others. None of these happened to carpenter, thus all are false allegations. His claim on negligent and intentional infliction of emotional distress will fail because there might have been emotional distress inflicted. It might as well have been self-inflicted since the same appraisal system was being used on all other employees and such complains had not been raised by any other employee. The only Carpenters claim that might succeed against Mills is that of lack of an appeal process for employees against the appraisal approach. Take for example in the case of Bob crane, the second supervisor of Carp enter. He just formulated the objectives on his own and brought them to carpenter. In my opinion, Carpenter should have also been given a chance to contest the objectives, which he thought were too difficult for him to achieve. Elements of a legally defensible performance appraisal system A legally defensible performance appraisal should be in writing and should contain the specific procedures to be followed. It must also specify the documentation to be used and the specific instructions for supervisors. There should be proper training for the supervisors on how to evaluate and administer the system. An objective should be established and standardized forms of related groups of employees should be used. The system should also be thoroughly communicated to employees and be given to them formally at least every once in a year. Finally, the system should be reviewed periodically to ensure it is right and up to date. References Aguinis, H. (2012). Performance Management.

Biography of Mary Jackson, NASAs First Female Black Engineer

Biography of Mary Jackson, NASA's First Female Black Engineer Mary Jackson (April 9, 1921 – February 11, 2005)  was an aerospace engineer and mathematician for the National Advisory Committee for Aeronautics (later the National Aeronautics and Space Administration). She became NASA’s first black female engineer and worked to improve hiring practices for women at the administration. Fast Facts: Mary Jackson Full Name:  Mary Winston JacksonOccupation: Aeronautical engineer and mathematicianBorn: April 9, 1921 in  Hampton, VirginiaDied:  February 11, 2005 in Hampton,  VirginiaParents:  Frank and Ella WinstonSpouse:  Levi Jackson Sr.Children: Levi Jackson Jr. and Carolyn Marie Jackson LewisEducation: Hampton University, BA in mathematics and BA in physical science; further graduate training at the University of Virginia Personal Background Mary Jackson was the daughter of Ella and Frank Winston, from Hampton, Virginia. As a teenager, she attended the all-black George P. Phenix Training School and graduated with honors. She was then accepted to Hampton University, a private, historically black university in her hometown. Jackson earned dual bachelor’s degrees in mathematics and physical science and graduated in 1942. For a time, Jackson found only temporary employment and jobs that did not line up fully with her expertise. She worked as a teacher, a bookkeeper, and even as a receptionist at one point. Throughout this time- and, in fact, throughout her life- she also privately tutored high school and college students. In the 1940s, Mary married Levi Jackson. The couple had two children: Levi Jackson Jr. and Carolyn Marie Jackson (later Lewis). Computing Career Mary Jackson’s life continued in this pattern for nine years until 1951. That year, she became a clerk at the Office of the Chief Army Field Forces at Fort Monroe, but soon moved to another government job. She was recruited by the National Advisory Committee for Aeronautics (NACA) to be a â€Å"human computer† (formally, a research mathematician) in the West Computing group at the organization’s Langley, Virginia facility. For the next two years, she worked under Dorothy Vaughan in the West Computers, a segregated division of black female mathematicians. Mathematician Mary Jackson, the first black woman engineer at NASA poses for a photo at work at NASA Langley Research Center in 1977 in Hampton, Virginia.   Bob Nye / NASA / Getty Images In 1953, she began working for engineer Kazimierz Czarnecki in the Supersonic Pressure Tunnel. The tunnel was a crucial apparatus for research on aeronautical projects and, later, the space program. It functioned by generating winds so fast that they were nearly twice the speed of sound, which was used to study the effects of forces on models. Czarnecki was impressed by Jacksons work and encouraged her to get the qualifications necessary to be promoted to a full engineer position. However, she faced several obstacles to that goal. There had never been a black female engineer at NACA, and the classes Jackson needed to take in order to qualify weren’t easy to attend. The problem was that the graduate-level math and physics classes she needed to take were offered as night classes through the University of Virginia, but those night classes were held at the nearby Hampton High School, an all-white school. Jackson had to petition the courts for permission to attend those classes. She was successful and was permitted to finish the courses. In 1958, the same year that NACA became NASA, she was promoted to aerospace engineer, making history as the organization’s first black female engineer. Groundbreaking Engineer As an engineer, Jackson remained at the Langley facility, but moved over to work at the Theoretical Aerodynamics Branch of the Subsonic-Transonic Aerodynamics Division. Her work focused on analyzing data produced from those wind tunnel experiments as well as actual flight experiments. By gaining a better understanding of air flow, her work helped improve aircraft design. She also used her wind tunnel knowledge to help her community: in the 1970s, she worked with young African American children to create a mini version of a wind tunnel. Over the course of her career, Mary Jackson authored or co-authored twelve different technical papers, many about the results of the wind tunnel experiments. By 1979, she achieved the most senior position possible for a woman in the engineering department, but could not break through to management. Instead of remaining at this level, she agreed to take a demotion in order to work in the Equal Opportunity Specialist department instead. She received specialized training at NASA headquarters before returning to the Langley facility. Her work focused on helping women, black employees, and other minorities advance in their careers, advising them on how to get promotions and working to highlight those who were particularly high-achieving in their particular fields. During this time in her career, she held multiple titles, including Federal Women’s Program Manager in the Office of Equal Opportunity Programs and Affirmative Action Program Manager. In 1985, Mary Jackson retired from NASA at the age of 64. She lived for another 20 years, working in her community and continuing her advocacy and community engagement. Mary Jackson died on February 11, 2005 at the age of 83. In 2016, she was one of three main women profiled in Margot Lee Shetterly’s book Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race and its subsequent movie adaptation, in which she was portrayed by Janelle Mone.
