Mandatory Birth Control Welfare Requirement Debate Essay Example

Mandatory Birth Control Welfare Requirement Debate Paper The American welfare system began in the 1930s, during the Great Depression, to aid families with little or no income. The welfare system expanded over the following six decades. Allegations of welfare fraud and abuse increased proportionally. Some welfare recipients were staying unmarried, unemployed, or acquiring more children to manipulate the system and qualify for more aid (Welfareinfo.org, 2013). In 1996, President Bill Clinton signed a bill turning control of the welfare system over to the individual states. Thus, allowing states to choose their preferred mechanisms to modify the requirements and restrictions of welfare applicants and recipients to minimize the abuses. Both sides of the aisle have introduced bills to eliminate funding to chronic welfare abuses and preserve the limited welfare funds for families and individuals in genuine need of temporary financial assistance. Despite sounding like an oxymoron, political officials have the most appropriate career competency for understanding state laws and determining the better courses of action for preserving state tax revenues.

Stephen Finchers (R-Tenn) put forth a bill that would require states to perform random drug tests on 20% of the people receiving benefits from the Temporary Assistance for Needy Families (TANF) program. The bill did not pass the Congress. Rep. Fincher intends to revise the bill and submit for a vote later. On February 2, 2009, the Obama administration revised the TANF program adding a requirement that welfare recipients must take an active role in searching for employment, and to remain employed when possible. Numerous other bills have been introduced in Congress over the years to address the issues of drug use, intentional unemployment, and fraud in state or federal subsidized programs. Adding children to a family already in welfare programs increases the amount of welfare payment and extends the amount of time a person can be unemployed and receive taxpayer funded welfare. Some welfare recipients have additional children simply as a way to profit from the system. The topic of this debate will be: Should individuals, enrolled in a government assistance programs, be required to be on birth control to receive benefits? This debate paper will begin with three arguments from the pro perspective, followed by three arguments from the con perspective. The merits of these debate arguments will be discussed, followed by a conclusion based on the team’s determination of the stronger set of arguments. Lastly, the weaker perspective will offer a rebuttal to the team’s conclusion. Pro Arguments Foster Child and Adoption Programs A person qualifies for welfare when he or she does not have the means, or ability to provide adequately for them self. Social service agencies will not place foster or adoptive children in economically unstable household to ensure the child’s needs are adequately met. As a ward of society and for the protection of unborn children, a welfare recipient should be required to be on birth control and meet the same standards required for adoptive or foster parents before mandatory birth control can be suspended. Doing this would mirror the social service guidelines already established, which ensure children’s need can be adequately met by their guardians, and also prevents additional burdens on the welfare system. Social Responsibilities and Constitutional Rights The Constitution holds an individuals rights to be inalienable. The Supreme Court has ruled that citizen rights are exercised only to the extent that they do not infringe on the rights of another. Therefore, irresponsible reproduction by welfare recipients infringes upon the rights of fellow Americans, by forcing them to support the reckless behavior of the welfare recipient. Further, welfare is an entitlement program, not a constitutional right. The government has numerous restrictions and requirement for social security, unemployment, education, and every other entitlement program. Those restrictions preserve the intent of the programs and reduce abuses. This requirement is simply asking potential mothers and fathers to take responsibility for their own actions. Having children should not be forbidden; however, temporarily restrictions while a potential mother or father is dependent upon taxpayer backed state assistance should be required. This should help eliminate many of the cases of welfare abuse by decoupling the desire to have children and the current financial incentive of welfare recipients to have more children. This creates a further incentive for seeking employment and self improvement of potential mothers or fathers wanting children and should reduce the amount of time a recipient stays in the welfare system. Universal Health care and contraception A person should be required to use birth control to receive government assistance if he or she is cannot to support and feed themselves and any children he or she already has. If this person refuses to participate in preventative measures for religious or other reasons then monetary assistance should eliminated if they were to have another pregnancy. The state should provide free contraception to them as part of their assistance. Free vasectomies to the men should be offered as part of this program. Con Arguments Religious conflict to birth control A person should not be forced to take birth control to receive assistance if he or she chooses not to. Many religious beliefs do not permit contraception to be used. The Catholic Church, for example, is one. If God wants a person to have a child, what right does the state or federal government have to override His will? Social Responsibilities and Constitutional Rights The Constitution of the United States of America gives the same rights and protections to all persons regardless of their employment or income status. The government has no authority to regulate when, why, or how often any person procreates. Requiring that welfare recipients submit to birth control to receive welfare benefits is a violation of that person’s constitutional rights. Such a draconian measure will harm families and promote suffering of innocent children who welfare recipients already have. For the government to cut off a citizen’s rightful assistance for the very natural and inalienable right of procreation is tyrannical and stands in stark contract to every principle that this great country was founded. Universal Health Care and Contraception Before an individuals reproductive rights are taken away, we must speak of global access to birth control. Does a welfare recipient pose a higher long-term risk, compared to a teenage mother? Focusing birth control mandates on citizens who are already struggling with hard times will not address the broader issues of decreasing the demands on the welfare system. Planned Parenthood, one of the largest sources of free and low-cost birth control, and has experienced countless budget cuts, year after year. These budget cuts make providing services to the neediest participants extremely difficult. What other services will need to be provided in the long term to young mothers. Better funding of family planning programs is a better use of tax payer dollars. Providing more funding to family planning clinics provides solutions to individuals who are actively seeking family planning rather than infringing on the rights stereotyped group who find themselves needing help, not oppression. Welfare Requirements Debate In an evaluation of the arguments presented, Team D has determined that the pro side of this debate presented stronger arguments. Several logic errors or fallacies were noted in the con arguments, which further weakened the strengths of the con side of the debate. There were two direct parallels between the pro and con arguments. One of the set of arguments is not directly paired, but did overlap with some relevance. The team determined at the con argument of religious belief is a fallacy, shifting the burden of proof. The con argument of universal health care addresses the religious argument without side stepping the issue. The team evaluation also determined the con argument is an argument from popularity. Further, the separation of church and state should not allow or require that state welfare policies cater to individual religious concerns. There are numerous legal precedents, such as Roe v Wade that establish government policy despite conflicting religious perspective. On the issue of constitutional rights, the team opinion again found the pro argument better reasoned. The most convincing aspects of the pro argument were welfare is an entitlement program, not a constitutional right, and entitlement programs can place restrictions. This was viewed as the pro side providing legal precedent. The con side is a statement of faulty comparison and does not provide any counterargument to pro side’s establishment of the legal precedent. The arguments of universal health care were also determined stronger on the pro side. While neither side had a particularly strong argument, the pro side did provide a rebuttal to the religious argument of the con side. The con argument is not substantive to the debate and is considered to be a red herring. The team concludes the pro side presented a strong case for each of the arguments. Since, welfare benefits are not constitutionally mandated, and individual’s rights to procreate freely are not protected under the Constitution. States should have the liberties to decide requirements that must be met to use welfare benefits, including use of mandatory birth control. Rebuttal The government has the responsibility to protect its citizen’s rights and responsibilities, not remove them. Regardless of whether welfare is an entitlement program or a right, the government does not have the authority to make family planning decisions for its citizens. Such actions would be a clear and blatant violation of constitutional rights. Imposing such requirements on welfare recipients is not simply a slippery slope, but an avalanche of issues that have not been discussed or evaluated by the proponents of mandatory birth control. What recourse will women have if they suffered any of the potential side effects of birth control such as decreased fertility, hormone regulation, depression, mood disorders? What happens to the people kicked off the welfare system? Are they left to starve? The moral wrongs of this requirement far outweigh any tax saving biased statisticians can produce. Abuses and fraud may exist in the welfare system, but mandatory birth control is not an effective approach to try to address that. The many who depend on the welfare system would be undeservedly punished for the crimes of a few that take advantage of it. Mandatory birth control is a one-size fits all approach, like using a nuclear bomb to swat flies. There are many other approaches that can and should be taken that can achieve the goal of reducing fraud and protecting the rights of families. Many mothers cannot work because the cost of childcare is greater than the income they can earn. Creating more affordable childcare programs would aid to get mothers in the workforce and off the welfare roles. Sick children cannot go to school or daycare, which means mothers cannot work and cannot earn money when their children are sick. Health care is prohibitively expensive. Affordable health care or access to universal health care would create healthier children and allow them to stay in school or daycare. This cycle of mothers having to leave work to stay at home with their sick children has been the very cause of many mothers losing steady employment and end up dependent on welfare. These are just a few of many alternatives that would create a positive impact on all parties involved and reduce dependence on the welfare system. There are better ways to preserve and protect the welfare system and families. For these reasons and many more, birth control should not be made as a mandatory part of receiving welfare benefits.

Basic Facts about U.S. Territories

Basic Facts about U.S. Territories The United States is the worlds third largest country based on population and land area. It is divided into 50 states but also claims 14 territories around the world. The definition of a territory as it applies to those claimed by the United States are lands that are administered by the United States but are not officially claimed by any of the 50 states or any other world nation. Typically, most of these territories depend on the United States for defense, economic and social support. The following is an alphabetical list of the territories of the United States. For reference, their land area and population (where applicable) have also been included. American Samoa Total Area: 77 square miles (199 sq km) Population: 55,519 (2010 estimate) American Samoa is made up of five islands and two  coral atolls, and is  part of the Samoan Islands chain in the south Pacific Ocean. The  1899 Tripartite Convention divided the Samoan Islands into two parts, between the US. and Germany, after more than a century of battles among the French, English, German and Americans to claim the islands, during with the Samoans fought fiercely. The U.S. occupied its part of Samoa in 1900 and on  July 17, 1911, the US Naval Station Tutuila  was officially renamed American Samoa. Baker Island Total Area: 0.63 square miles (1.64 sq km) Population: Uninhabited Baker Island an atoll just north of the equator in the central Pacific Ocean about 1,920 miles southwest of Honolulu. It became an American territory in 1857. Americans tried to inhabit the island in the 1930s, but when Japan became active in the Pacific during World War II, they were evacuated. The island is named for Michael Baker, who visited the island several times before claiming it in 1855. It was classified as part of Baker Island National Wildlife Refuge in 1974. Guam Total Area: 212 square miles (549 sq km) Population: 175,877 (2008 estimate) Located in the western Pacific Ocean  in the Mariana Islands, Guam became a U.S. possession in 1898, following the Spanish-American War. Its believed that the indigenous people of Guam, the Chamorros, settled on the island roughly 4,000 years ago. The first European to discover Guam was Ferdinand Magellan in 1521. The Japanese occupied Guam in 1941, three days after the attack on Pearl Harbor in Hawaii.  American forces liberated the island on July 21, 1944, which is still commemorated as Liberation Day. Howland Island Total Area: 0.69 square miles (1.8 sq km) Population: Uninhabited Located near Baker Island in the central Pacific, Howland Island comprises the  Howland Island National Wildlife Refuge and is managed by the U.S. Fish and Wildlife Service. Its part of the Pacific Remote Islands Marine National Monument. The U.S. took possession in 1856. Howland Island was the destination aviator Amelia Earhart was headed for when her plane disappeared in 1937.   Jarvis Island Total Area: 1.74 square miles (4.5 sq km) Population: Uninhabited This uninhabited atoll is in the south Pacific Ocean halfway between Hawaii and the Cook Islands. It was annexed by the U.S. in 1858, and is administered by  the Fish and Wildlife Service as part of the National Wildlife Refuge system.   Kingman Reef Total Area: 0.01 square miles (0.03 sq km) Population: Uninhabited Although it was discovered a few hundred years earlier, Kingman Reef was incorporated by the U.S. in 1922. Its incapable of sustaining plant life, and is considered a maritime hazard, but its location in the Pacific Ocean had strategic value during World War II. Its administered by the U.S. Fish and Wildlife Service as the  Pacific Remote Islands Marine National Monument. Midway Islands Total Area: 2.4 square miles (6.2 sq km) Population: There are no permanent inhabitants on the islands but caretakers periodically live on the islands. Midway is nearly at the halfway point between North America and Asia, hence its name. Its the only island in the Hawaiian archipelago which is not part of Hawaii. Its administered by the U.S. Fish and Wildlife Service. The U.S. formally took possession of Midway in 1856.   The Battle of Midway was one of the most important between the Japanese and the U.S. in World War II. In May 1942, the Japanese planned an invasion of Midway Island which would provide a base for attacking Hawaii. But the Americans intercepted and decrypted the Japanese radio transmissions.  On June 4, 1942, U.S. aircraft flying from USS Enterprise, USS Hornet, and USS Yorktown attacked and sunk four Japanese carriers, forcing the Japanese to withdraw. The Battle of Midway marked the turning point of World War II in the Pacific. Navassa Island Total Area: 2 square miles (5.2 sq km) Population: Uninhabited   Located in the Caribbean 35 miles west of Haiti, Navassa Island is administered by the U.S. Fish and Wildlife Service. The U.S. claimed possession of Navassa in 1850, although Haiti has disputed this claim. A group of Christopher Columbus crewmen happened on the island in 1504 on their way from Jamaica to Hispanola, but discovered Navassa had no fresh water sources. Northern Mariana Islands Total Area: 184 square miles (477 sq km) Population: 52,344  (2015 estimate) Officially known as the Commonwealth of the Northern Mariana Islands, this string of 14 islands is in the Micronesia collection of islands in the Pacific Ocean, between Palau, the Philippines and Japan.   The Northern Mariana Islands have a tropical climate, with December through May as the dry season, and July to October the monsoon season. The largest island in the territory, Saipan, is in the Guinness Book of Records for having the worlds most equable temperature, at 80 degrees year round. The Japanese had possession of the Northern Marianas until the U.S. invasion in 1944.   Palmyra Atoll Total Area: 1.56 square miles (4 sq km) Population: Uninhabited Palmyra is an incorporated territory of the U.S., subject to all provisions of the Constitution, but its also an unorganized territory, so theres no Act of Congress on how Palmyra should be governed. Located halfway between Guam and Hawaii, Palmyra has no permanent residents, and is administered by the U.S. Fish and Wildlife Service. Puerto Rico Total Area: 3,151 square miles (8,959 sq km) Population: 3, 474,000  (2015 estimate) Puerto Rico is the easternmost island of the Greater Antilles in the Caribbean Sea, about 1,000  miles southeast of Florida and just east of the Dominican Republic and west of the U.S. Virgin Islands. Puerto Rico is a commonwealth, a territory of the U.S. but not a state. Puerto Rico seceded from Spain in  1898, and Puerto Ricans have been citizens of the United States since a law was passed in 1917. Even though they are citizens, Puerto Ricans pay no federal income tax and they can not vote for president. U.S. Virgin Islands Total Area: 136 square miles (349 sq km) Population: 106,405  (2010 estimate) The islands that make up the U.S. Virgin Islands archipelago in the Caribbean  are St. Croix, St. John and St. Thomas, as well as other minor islands. The USVI became a U.S. territory in 1917, after the U.S. signed a treaty with Denmark. The territorys capital is Charlotte Amalie on St. Thomas. The USVI elect a delegate to Congress, and while the delegate can vote in committee, he or she cant participate in floor votes. It has its own state legislator and elects a territorial governor every four years. Wake Islands Total Area: 2.51 square miles (6.5 sq km) Population: 94  (2015 estimate) Wake Island is a coral atoll in the western Pacific Ocean 1,500 miles east of Guam, and 2,300 miles west of Hawaii. Its an unorganized, unincorporated territory is also claimed by the Marshall Islands. It was claimed by the U.S. in 1899, and is administered by the U.S. Air Force.

An International and Comparative Human Resource Management Essay

An International and Comparative Human Resource Management - Essay Example As the essay states globalization of markets is an important aspect of modern world system which involves all areas of public life, including economy, politics, social sphere, culture, ecology, and safety. It is one of the most influential forces determining the international HRM. Development of IHRM becomes important in maintenance of human relationships and ensuring the physical well-being of employees so that they give the maximum contri ¬bution to efficient working. It is obviously closely related to the management process as a whole and each functional manager and supervisor must apply the principles effectively. According to the discussion findings International HRM have a great influence on the global consumer market as well. The transition to the knowledge economy, globalisation, and omnipresence of information and communication technologies (ICT) require a permanent updating of the skills and competences of organizational workforce. Business is not all about profit but also for organizational value creation. Organizational values in MNEs involve providing opportunities for employees’ development and self-realization, pursuing unmatched product quality, creating a safe working environment, and working for the improvement of the natural environment. . The aim of the paper is to apply the concepts of International HRM and comparative HRM for analyzing practices of P&G in South Korea. Information about the MNE's background (Proctor & Gambler) P&G is a multinational enterprise which operates in 160 countries around the world. Its main activity includes manufacturing of consumer, pharmaceutical and household products for diverse target audience. After the Second World War, P&G had started its international and global expansion in manufacturing and sales. In 1954 P&G has started its international activity in Europe leasing a detergent manufacturer.In 1980 P&G became a global company, and after a period of successful mergers and acquisitions with such brands as Noxell, Max Factor and Ellen Betrix, P&G expands its global presence. In 1993, the 50% of sales came outside the USA (Bob's River View, 2002). With the changing economic environment, globalization of markets, international economic integration and increased competition have enhanced the need of new strategies in international and global business. Today, it is one of the most important infrastructure requirements, which is essential for the expansion of opportunities and plays an important role in making or breaking the competitive positioning of P&G. The main products of the company can be divided into 6 categories: laundry and cleaning products, beauty

IMMIGRATION Essay Example | Topics and Well Written Essays - 1000 words

IMMIGRATION - Essay Example The U.S. has never been the melting pot that was expected. Instead, immigrant ethnic groups have maintained their unique identities for generation after generation. The immigrant heritage has worked itself into the basic fabric of American life. The cycle of anti-immigrant feelings and politics seems closely tied to economic issues: when the nation needs laborers, immigrants of all kinds are welcomed, when jobs are scarce, immigrants are excluded. (Purcell, p.xii). In â€Å"Unchecked Immigration† what is Peter Brimelow’s claim, and what solutions does he propose? Using secondary sources to advance your argument, state whether you agree or disagree with Brimelow’s claim and solutions. According to Peter Brimelow, in the article Unchecked Immigration, the 1965 Immigration Act triggered an influx of historically high proportions, particularly compared to current U.S. birth rates. If the present trends continue, the U.S. population will reach 390 million by 2050. More than a third of the population would be post-1970 immigrants and their descendants. Because the 1965 Act arbitrarily choked off immigration from Europe, this influx has been almost completely from the third world. As recently as 1960, whites who were 90% of the population, by 2050 will be on the verge of becoming a minority. A demographic transformation such as this is without precedent in the history of the world. Also, the 1990 census revealed that native-born Americans both black and white were fleeing from the immigrant-favored areas, where they were being replaced in equal numbers by immigrants. They fled to two different parts of the country, where their own people were. Peter Brimelow claims that the U.S. is coming apart ethnically under the impact of the enormous influx. He wonders whether America continues to be the integration of ethnicity and culture as a nation, and whether the American nation-state can survive. The solutions to the problem, that Peter Brimelow offers are that: In

Nature of an electron Coursework Example | Topics and Well Written Essays - 2250 words

Nature of an electron - Coursework Example This is described in a classical wave model of light; which states that light properties that are similar to any wave. For instance, light experiences reflection and refraction in the same manner that any other wave would experience interference. In addition, light experiences the Doppler effect the same way any other wave would experience Doppler effect. However, the prediction of the quantum model shows that frequency or wavelength of the incident of the incident light only affects the photoelectric current. where E- is the energy that the quantum light produces, Kmax is the maximum kinetic energy of the photoelectrom emitted , where as Wo is the work function of the of the energy needed to innitiate the emision of photoelectrons from the metal surface. In an experiment to demonstrate the photoelectric effect, the following apparatus are required: a digital voltmeter to be used to measure the reverse voltage reading, a photodiode connected with an amplifier, monochromatic light sou rce to produce light beams to irradiate the photo cathode, and a filter to neutrally vary the intensity of light. Generally the quantization energy of the electromagnetic radiation in light is given in the relation, where the radiation energy, is a constant known as the Plank’s constant and is given as (6.63?10^-34Js), and - is the frequency of the light incident energy. The validity of the equation is based on the photoelectric effect experiment. There are four aspects that need to be taken into consideration when conducting the photoelectric effect experiment. These facts include: the minimum frequency; when the frequency of the incident light is less than the minimum frequency required, no photoelectrons can be emitted despite the intensity of the light. The value of minimum frequency varies from metal to metal. Secondly, as the frequency of the incident light increases, the kinetic energy of the photoelectrons increases. However, the intensity of the light is independent of the kinetic energy of the electron emitted. And lastly, the emission of photons is effectively instantaneous. (physics 242 laboratory manual) The photoelectric effect experiment consists if a high intensity lamb, a phototube, and batteries. The photodiode tube is the central element of the apparatus. The window in the diode gives way for light into the tube to the clean metal surface at the cathode. The diode is completely evacuated to avoid any collision of air molecules and the electrons. When beams of light hit the surface of the metal plate at the cathode, electrons are emitted by the metal plate. The photodiode has an in-built capacitance developing a voltage during the charging process by the electrons emitted. When the stopping potential of the cathode is reached, the difference in voltage across the two poles, that is, cathode and anode stabilizes. A very sensitive amplifier is used to measure the stopping potential. The amplifier aids in the establishment of the small nu mber of photoelectrons emitted. A voltmeter is used to measure the output voltage of the between the batteries and the output ground terminals. A number of different monochromatic light beams are used for the experiment. A glass tube consisting of mercury vapor produces light when discharged electrically. The glasses envelop filters out the ultraviolet light that can be harmful. The mercury light produces five thin spectral lines that are: yellow, green blue, violet, and ultraviolet in the visible region. These lines can be spatially separated by diffraction. The wavelength desired is selected using a collimator, and the intensity of the selected wavelength is varied using a density filter The mercury lamb is switched on. On the front reflective mask of the lamb box, yellow, green, and tiny rays of blue
