Advertisements are usually meant to make products to be bought more by customers. Business people try to use the most effective means of advertisement in order to have competitive advantage of other businesspersons in the market. Despite that, advertisements are meant to attract more customers there are too dangerous to be marketed because of the danger that they pause to both the customers and the society in general. We will write a custom essay sample on Business Ethics 5 – Products and Advertising or any similar topic only for you Order Now For example, people mostly abuse handguns, cigarettes, and some drugs whiuch. In order to market such products there should be strict measures, which should be put in place by the federal government to control the effects of the products, which may cause harm. The American marketing association commits itself to make sure that there is promotion of highest standard of professional ethical norms and values to all its members. Marketers should understand that they do not only work for the organizations but they should also act as the custodian in undertaking activities that bring good to the larger population. This means that marketers are supposed to maintain high standards of ethical norms and ethical values. In order to protect the society from harmful effects of marketing of products that are dangerous there are regulations that I would put to marketing of these product. (DesJardins Hartman, 2008). For cigarettes due to its negative health, effects it has it would be appropriate for markets to put a label on the cigarettes, which warns the smoker that the cigarette is harmful to his or her health and to the health of other members of the society. There should also be no program in the media, which should be sponsored by companies, which manufacture cigarettes. This would reduce creation of positive attitude about cigarettes to the public, which may lead to its increased consumption. The marketers should also not be allowed to put the large posters, which are used for advertisement in public places such as rods. For prescription, drugs there should be a regulation that the drugs should only be sold to those people who have a note from a physician prescribing him or her to take the drugs. They should also a label, which Cleary shows the negative effects they have if abused. For the handguns there should be registering of any handgun that is purchased this would help to reduce criminals obtaining them, licensing of handgun owners, there should also be prohibition of mentally ill people from obtaining handguns. All these regulations would protect the society from many negative effects caused by marketing of handguns. 2. There are usually two criteria that the federal trade commissions use to regulate advertisement. They use deception and fairness as the two criteria. An advertisement is unfair if it has harmful effects to the consumer. For example, if it is an advertisement of a product, which causes negative health effects, then such an advertisement can be termed was unfair. Deceptive advertisement is an advertisement, which uses false or misleading statements to attract customers. Deceptive advertising usually hurts the customers because they may contain statements, which may not be true, which may rue the customer to buy a certain product. This is because the advertisement may contain hidden fees and charges or manipulation of standards of the goods. There is decision-making process, which is used to determine how an advertisement can be unfair. One-step in this process includes looking whether the advertisement hurt and cause injuries the customer. If the advertisement is found to do this then it is taken to be unfair. The injury should be substantial in terms of monetary such as the seller forcing the buyer to goods or services, which are not wanted. The injury, must also be one that the customer could not have reasonably avoided. This is because market place should be self-correcting. The other step involves looking whether the advertisement violates the established public policy, which governs advertisement. Then there is an examination on whether the advertisement is unethical or unscrupulous. The advertisement should also give the consumer sufficient information so that the customer can be able to make informed decisions (DesJardins Hartman, 2008). References DesJardins, J. Hartman, L.

Nuclear Reactors and Energy free essay sample

An examination of the process by which nuclear reactors produce energy. This paper explains how a nuclear reactor produces energy. The paper includes a discussion of fission, radioactivity, types of reactors and how they produce electricity. All modern nuclear reactors operate on the principal of nuclear fission. Nuclear fission is a process in which the nucleus of an atom is split when it absorbs a free neutron after a collision occurs between the atom and the neutron. Splitting the nucleus of the atom releases large amounts of nuclear energy contained within the nucleus. Once the nucleus of the atom is split, multiple neutrons are released which are used to split nuclei of other atoms, causing what is known as a chain reaction. The chain reaction will continue as long as an average of one neutron per fission is absorbed by a nucleus. By harnessing and manipulating the energy that is released, other types of energy can be obtained. We will write a custom essay sample on Nuclear Reactors and Energy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The power developed by nuclear fission has been used by man to create, as in the driving of an electric generator and for propulsion, as well as destroy, as in the release of atomic explosion. Whereas the fission in a nuclear reactor is precisely controlled to prevent a nuclear meltdown, the fission in an atomic explosion is not controlled and the shock wave produced by the splitting atom and its resulting chain reaction is equal to several thousand tons of TNT.

Early Explorers of Africa

Early Explorers of Africa Even in the 18th century, much of the interior of Africa was unfamiliar to Europeans. Most of their time in Africa was limited to trade along the coast, first in gold, ivory, spices, and later slaves. In 1788 Joseph Banks, the botanist whod sailed across the Pacific Ocean with Cook, went as far as to found the African Association to promote the exploration of the interior of the continent. Ibn Battuta Ibn Battuta (1304-1377) traveled over 100,000 kilometers from his home in Morocco. According to the book he dictated, he traveled as far as Beijing and the Volga River; scholars say its unlikely he traveled everywhere he claims to have. James Bruce James Bruce (1730-94) was a Scottish explorer who set off from Cairo in 1768 to find the source of the River Nile. He arrived at Lake Tana in 1770, confirming that this lake was the origin of the Blue Nile, one of the tributaries of the Nile. Mungo Park Mungo Park (1771-1806) was hired by the African Association in 1795 to explore the River Niger. When the Scotsman returned to Britain having reached the Niger, he was disappointed by the lack of public recognition of his achievement and that he was not acknowledged as a great explorer. In 1805 he set out to follow the Niger to its source. His canoe was ambushed by tribesmen at the Bussa Falls and he drowned. Renà ©-Auguste Caillià © Renà ©-Auguste Caillià © (1799-1838), a Frenchman, was the first European to visit Timbuktu and survive to tell the tale. Hed disguised himself as an Arab to make the trip. Imagine his disappointment when he discovered that the city wasnt made of gold, as legend said, but of mud. His journey started in West Africa in March 1827, headed towards Timbuktu where he stayed for two weeks. He then crossed the Sahara (the first European to do so) in a caravan of 1,200 animals, then the Atlas Mountains to reach Tangier in 1828, from where he sailed home to France. Heinrich Barth Heinrich Barth (1821-1865) was a German working for the British government. His first expedition (1844-1845)was from Rabat (Morocco) across the coast of North Africa to Alexandria (Egypt). His second expedition (1850-1855) took him from Tripoli (Tunisia) across the Sahara to Lake Chad, the River Benue, and Timbuktu, and back across the Sahara again. Samuel Baker Samuel Baker (1821-1893) was the first European to see the Murchison Falls and Lake Albert, in 1864. He was actually hunting for the source of the Nile. Richard Burton Richard Burton (1821-1890) was not only a great explorer but also a great scholar (he produced the first unabridged translation of The Thousand Nights and a Night). His most famous exploit is probably his dressing as an Arab and visiting the holy city of Mecca (in 1853) which non-Muslims are forbidden to enter. In 1857 he and Speke set off from the east coast of Africa (Tanzania) to find the source of the Nile. At Lake Tanganyika Burton fell seriously ill, leaving Speke to travel on alone. John Hanning Speke John Hanning Speke (1827-1864) spent 10 years with the Indian Army before starting his travels with Burton in Africa. Speke discovered Lake Victoria in August 1858 which he initially believed to be the source of the Nile. Burton didnt believe him and in 1860 Speke set out again, this time with James Grant. In July 1862 he found the source of the Nile, the Ripon Falls north of Lake Victoria. David Livingstone David Livingstone (1813-1873) arrived in Southern Africa as a missionary with the aim of improving the life of Africans through European knowledge and trade. A qualified doctor and minister, he had worked in a cotton mill near Glasgow, Scotland, as a boy. Between 1853 and 1856 he crossed Africa from west to east, from Luanda (in Angola) to Quelimane (in Mozambique), following the Zambezi River to the sea. Between 1858 and 1864 he explored the Shire and Ruvuma river valleys and Lake Nyasa (Lake Malawi). In 1865 he set off to find the source of the River Nile. Henry Morton Stanley Henry Morton Stanley (1841-1904) was a journalist sent by the New York Herald to find Livingstone who had been presumed dead for four years as no-one in Europe had heard from him. Stanley found him at Uiji on the edge of Lake Tanganyika in Central Africa on 13 November 1871. Stanleys words Dr. Livingstone, I presume? have gone down in the history as one of the greatest understatements ever. Dr. Livingstone is said to have replied, You have brought me new life. Livingstone had missed the Franco-Prussian War, the opening of the Suez Canal, and the inauguration of the transatlantic telegraph. Livingstone refused to return to Europe with Stanley and continued on his journey to find the source of the Nile. He died in May 1873 in the swamps around Lake Bangweulu. His heart and viscera were buried, then his body was carried to Zanzibar, from where it was shipped to Britain. He was buried at Westminster Abbey in London. Unlike Livingstone, Stanley was motivated by fame and fortune. He traveled in large, well-armed expeditions he had 200 porters on his expedition to find Livingstone, who often traveled with only a few bearers. Stanleys second expedition set off from Zanzibar towards Lake Victoria (which he sailed around in his boat, the Lady Alice), then headed into Central Africa towards Nyangwe and the Congo (Zaire) River, which he followed for some 3,220 kilometers from its tributaries to the sea, reaching Boma in August 1877. He then set off back into Central Africa to find Emin Pasha, a German explorer believed to be in danger from warring cannibals. The German explorer, philosopher, and journalist Carl Peters (1856-1918) played a significant role in the creation of Deutsch-Ostafrika (German East Africa) A leading figure in the Scramble for Africa Peters was ultimately vilified for his cruelty to Africans and removed from office. He was, however, considered a hero by the German emperor Wilhelm II and Adolf Hitler. Mary Kingsley's Mary Kingsleys (1862-1900) father spent most of his life accompanying noblemen around the world, keeping diaries and notes which he hoped to publish. Educated at home, she learned the rudiments of natural history from him and his library. He employed a tutor to teach his daughter German so she could help him translate scientific papers. His comparative study of sacrificial rites around the world was his major passion and it was Marys desire to complete this which took her to West Africa after her parents deaths in 1892 (within six weeks of each other). Her two journeys werent remarkable for their geological exploration, but were remarkable for being undertaken, alone, by a sheltered, middle-class, Victorian spinster in her thirties without any knowledge of African languages or French, or much money (she arrived in West Africa with only  £300). Kingsley did collect specimens for science, including a new fish which was named after her. She died nursing prisoners of war in Simons Town (Cape Town) during the Anglo-Boer War. The article is a revised and expanded version of that first published on 25 June 2001.

Bach analysis Essay Example | Topics and Well Written Essays - 1500 words

Bach analysis - Essay Example And just as important it stands a clear testimony of the skill and wonder of Johann Sebastian Bach as the foundational composer of Western music. This portrayal of â€Å"Herr, unser Herrsche† is so rendered by the Cologne Cathedral Boys’ Choir.1 Conductor Eberhard Metternich has shaped the quivering triple-like motif that is later carried through the lower instrument voices as a continuum expressed and released on a recurring sixteenth motif. The accents on the third, and the first in the phrases of four sixteenths maintain the triple feel activeness or energy of the quiver. Durr describes the motif as an enhancement over "a persistent pedal point" that is latter carried into the voices 2. The contrast of the strong pedal and the persistent repeating motif to dictate rises and falls in emotional feeling is perhaps indicative of the tools and techniques Bach has, at that time in his life, finally polished to display skillful and precise artistic control. Bach wrote his m usic through the Lutheran Christian frame of reference. He guided it through the Baroque frame of the Enlightenment to its decorative height, by way of the Saint John Passion and the Magnificant, to his magnus opus, as noted and appreciated by so many, the St. Matthew Passion. \ Discussion The St. John Passion was first performed in 1724 as Bach entered the first prolific period of his Leipzig phrase. As the New Canto zu St. Thomae, some believed he had written the work earlier in preparation for the Good Friday performance, the high point of the year for music in the Lutheran church.3 The work covers the Passion play biblical narrative in John 18:1 to 19:42 and enabled Bach to realize an uninterrupted and thematic score for the chorales and the arias. The work leads up to the Pontius Pilate tribunal scene in Part II where it ends with the Golgatha and burial scene. Repeated text passages were used, along with repeated crowd scene responses to unify the work. Wolff identifies "inten sity and depth of expression" in the key sequence as it progressed later in part two. His sketch identifies Bach's precision toward foundation harmony. Chapter 19-22 is scored with three flats; through 24, four sharps; through 28, two flats; through 35, four flats; with the vocals and instruments expressing contrasting colors.4 Over the course of time, Bach took the Passion through several changes and never seemed quite satisfied with the final form. A year before his death, he had reworked almost half of the two part, 40 piece work. By that time he had reverted, after two major edition changes, back to the tighter original version. The problem he had was not a musical one but a libretto one. Wolff writes of it lacking textual unity.5 Bach uses familiar church hymns to develop some of the recitatives, arias, and choruses making up his work and draws from the work of other composers and poets for themes and ways of rendering the libretto. The music was written for a four-part chorus with solo tenor and bass, and a solo quartet of soprano, alto, tenor and base. Bass voices belong to Jesus, Peter, and Pilate, and the Evangelist is tenor. Instruments of the orchestra comprise two flutes, two oboes, viola da gamba, strings, lute and organ. Period instruments included viola da gama, two violas d'amore, continuo with cello and two oboes da caccia. The opening chorus is followed by the Evangelist recitative who sets the background for the betrayal of Jesus. Jesus sings to identify himself to the

A Hospitality Operator Might Face Assignment Example | Topics and Well Written Essays - 750 words

A Hospitality Operator Might Face - Assignment Example 4.) Factors that contribute to the bleakness and roughness of hospitality laws especially in the past were the small number of inns in which the innkeeper took the advantage of controlling the hospitality business. The hospitality law is considered as the foremost protector of the entire guests in this business (Cournoyer, et al., 2008). At present, there are already several establishments within the industry, and the presence of stiff competition is one determining factor for this occurrence (Cournoyer, et al., 2008). The nature of the hospitality management comprises the inclusion of the provision of services accommodation in the food and beverages business within a wide range of service establishments (Pizam, 2005, p. 53).These establishments include hotels, motels, clubs, casinos, restaurants, fast food outlets, and bars, to name a few. Hospitality management has also started growing inside shipping companies, rails, schools, hospitals, and so on (Pizam, 2005). Tourists are consi dered as the main factor why the hospitality business continues to develop and grow. It must be noted that the hospitality business provides the wider range of employment among people in both the rural and urban areas. 2. Worker Violence as a Legal Problem that a Hospitality Operator Might Face The hospitality operator is never exempted from encountering legal problems in hospitality management. ... Worker violence is identified in this paper as a legal problem that might be faced by the hospitality operator. Homicide appears to be one of the most extreme forms of violence manifested in the hospitality workplace (O’Fallon and Rutherford, 2011). According to US Department of Labor Occupational Safety and Health Administration (1998), homicide is the second cause of death of Americans working in the hospitality management. In 1996, data revealed that 912 workers account to the total work injuries in the US alone, indicating the seriousness of the homicide cases in the hospitality sector. A survey made by the National Crime Victimization of the Department of Justice indicates that there are about one million victims of violent crime at work, spanning from 1987 to 1992. Four categories are included in these data, specifically simple assault (615,160 victims); aggravated assault (264,174 victims); robbery (79,109 victims); and rape (13,068 victims). It appears that 159,000 cas es of victimization are reported annually in the hospitality business (US Department of Labor Occupational Safety and Health Administration, 1998). In 2002, 52 per cent of the service sector in 347 workplaces in the United States hospitality management has been a victim of homicide, according to the department of labor (O’Fallon and Rutherford, 2011, p. 229). Violence in the hospitality workplace is identified in two categories. Explicit violence, in which such violence directly involves the employees of a particular establishment, and implicit violence, in which the violence is specifically directed to the establishment (O’Fallon and Rutherford, 2011). The hospitality operator indeed faces a serious problem with the possibility of workplace violence occurring within his or her

WASTE INCINERATION Assignment Example | Topics and Well Written Essays - 2500 words

WASTE INCINERATION - Assignment Example The Producer Responsibility Obligations (Packaging Waste) Regulations (2005) 7. The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations (2006). (UK Waste†¦) It should be noted that the above list is not exhaustive. The purpose of all these legislation is to protect the environment and all natural substances such as air, water, land, animal, plants and surroundings, from the ill effects of hazardous chemicals and industrial wastes. The Risks Associated with Existing Incineration Sites Incinerations are not a right waste disposal technique for the following reasons. Destroying Valuable Resources Incineration of waste simply means that materials have been used only once and then are destroyed. It is a fact that all natural resources that we make use of have finite supplies. All natural resources whether it is iron, aluminum, copper, plastic, glass do not have unlimited supplies then why are we not thinking on recycling of these natural resources? Precious natural habitats and forests in Indonesia, Brazil, Malaysia, and Myanmar were exploited on mass scale for the supply of timber and production of pulp for paper mills. This is also the reason why some of the species have become extinct and natural ecological system has been put in jeopardy. Wood and paper recycling is need of the day to save our forest area. For that matter recycling of all natural produce is a necessity in these ever increasing consumer demands. A small study on SELCHP Incinerator It is a myth that incinerators finish the waste. Einstein’s principle holds true here also that matter cannot be destroyed but are only transformed from one form to another. Essentially, incinerators do not destroy them they just convert it into gases and ash. Household waste which is a cocktail of many harmful substances when burnt in incinerator produce many harmful gases and part of it gets released into atmosphere through chimney. The residue known as ash goes for landfill. Incinerators burn the wastes that create toxic fumes. Though the norms are made by regulatory authorities; often they are violated by the incinerator operators. Two incinerators that are in operation in south London (SELCHP) and North London (Edmonton) were fined for infringements innumerable times in the last 15 years. It is known that domestic waste contains fluorescent tubes and bulbs which have mercury in it, plastic materials, cadmium and many other harmful compounds. Besides, some of the electrical appliances contain cadmium, chromium and lead. They cause more volatile compounds in the heat of incinerator and generate dangerous vapors which get escape from chimneys of the incinerator into the atmosphere polluting natural environment and air. (SELCHP INCINERATOR 2002) Dioxin–a most Potent Threat to the Mankind The plastic materials like PVC, CPVC which contain bound chlorine with them and release dioxins when gets burnt. Dioxin, most toxic substan ce second only to radioactive waste, falls under the class of super-toxic chemicals that forms during burning of plastics and organic chemicals. In the past, people were made to leave the places such as Love Canal and Times Beach, Missouri due to excessive contamination of dioxin. Various plasticizers used in production processes of plastic are also
