Technological advancement or invention from 1815 to present Essay

Technological advancement or invention from 1815 to present - Essay Example Discussion Air conditioning was first conceptualized in the tradition of refrigeration. Refrigeration came about due to the need to preserve foods (Air Conditioning Systems). It was discovered that by keeping the temperature around food at below 4 degrees Celsius, it was possible to reduce the growth of bacteria and to prevent food spoilage. From the development of refrigeration, air conditioning came about. The basic foundations of refrigeration seen in 1824 indicated that liquefied ammonia could cool the air when it is evaporated (Air Conditioning Systems). These foundations laid the groundwork for the invention of the commercially available air conditioning units. The need for air conditioning was seen because industrialists saw the need to reduce air temperature in their industries. In 1902, Willis Haviland Carrier invented the first electrical air conditioning unit (Air Conditioning Systems). At that time, his invention was very much relevant in the manufacturing process of a pr inting plant where controlled temperature and humidity assisted in making the printing process more efficient because it maintained consistency in the paper size and ink alignment (Air Conditioning Systems). ... Carrier’s legacy was soon improved and conceptualized for its human suitability. However, not until 1928, with the discovery of Freon by Thomas Midgley, Jr. was the home use of air conditioning considered (Air Conditioning Systems). Freon was considered a safer and less toxic refrigerant. The invention of the Freon followed the more widespread of the air conditioner as its use was then seen in The White House in the 1930s; and in the 1940s and 1950s, its demand would continue to increase for many homes (Air Conditioning Systems). With these demands, the air conditioner also took on various physical changes, with its build being made smaller. Moreover, improvements to the technology integrated changes which included its applicability as a heating mechanism during winter months. Carrier patented his ‘apparatus for treating air’ in 1906. The term air conditioning was actually not Carrier’s term. It was coined and introduced by Stuart Cramer in a patent he file d in 1906 for a device he invented which incorporated water vapor to the air in textile plants (Bellis). Willis Haviland Carrier shared his Rational Psychometric Formula with the American Society of Mechanical Engineers in 1911 and this formula is still being used in the air conditioning industry today (Bellis). Due to Carrier’s invention, industries were able to operate well because they now had the ability to control temperature and humidity levels while operating their machineries and carrying out their work processes. Different industries like film, tobacco, processed meats, medical capsules, textiles, and other products were able to carry out their processes well without fear of straining their machineries and other equipment (Bellis). In 1921, Carrier patented the centrifugal

The Problems Of The Women In Current World Essay

The Problems Of The Women In Current World - Essay Example Research has been done on the present situation of the wage gap in the US in the last decade and the improvements made in the last 30 to 40 after the enforcement of equal wages acts and the women’s movement in mid 20th century. Women are still considered as second-grade custody workers in various job sectors. A decade ago in the US, the women were still being paid low as compared to the men for the same job that they were doing. Women caretakers and cleaners have a salary widely disparate from that of men and all because of gender difference. A salary gap of 8000 US dollars separated the women’s yearly income (22000 US Dollars) form the men’s yearly income (30000 US Dollars). (Barko 1) Even after 5 decades since the enforcement of the Equal Payment Act of 1963, American women earned 74 cents for every dollar earned by men, according to the study published jointly by the AFL-CIO and The Institute for Women’s Policy Research (IWPR), Washington (Barko 1). An increase in the wages of women task force employed across different industry sectors and in different categories would bring more than 50 % of low-income dual-earner and single-mother households above the poverty line. The recent study has challenged the age-old argument of lesser industry experience, childbearing time off and child rearing time off supporting the low income of women stating that 43 % of wage gap remains unexplained. After the industrial revolution in the late 19th and early 20th century, many new fields of work emerged and the professional world witnessed a boom. New posts were created, new organizations came into existence and new business lines became viable profit-making options.

Corruption and Multi-National Corporations Essay

Corruption and Multi-National Corporations - Essay Example Legally, facilitation payment is not allowed in the United Kingdom. However, it is allowed legally to certain extent in the United States (Special Cases, 2009). The issue of facilitation payment becomes specially challenging when doing business with a foreign country. The laws in a different country may or may not be similar to those your own country. Hence, this issue has to be studied clearly and carefully before deciding on its legal implications. Multi-national corporations operate in different countries all over the world. So it is not possible for them to work under one set of rules. Their memorandum of association must tally with the laws and customs of the host countries. They also have to do business with customers in the host countries as well as overseas. This makes the situation of facilitation payments more complicated if flexibility is not maintained (Special Cases, 2009). Research show that majority of multi-nationals have indulged in facilitation payments although they same majority would prefer not to make these payments. This is a catch-22 situation with the giver and taker harboring guilty conscience and yet performing the act in the larger interest of business (Gordon, Kathryn and Miyake, Maiko; 2001, p3) "Bribes can come in all sizes. ... ch-22 situation with the giver and taker harboring guilty conscience and yet performing the act in the larger interest of business (Gordon, Kathryn and Miyake, Maiko; 2001, p3) "Bribes can come in all sizes. The media likes to highlight the more flagrant examples, but the smaller, everyday forms often go undetected. In the past, governments have overlooked facilitation payments. Western lawmakers assumed that such payments were simply unavoidable, a necessary part of doing business abroad" (Wrage, Alexandra; 2009). Nonetheless, the issue does not stop at that. Time and again, facilitation payments have reached the courts and resulted in destabilizing outcomes. Daewoo is an example of a major multi-national firm collapsing owing to financial irregularities (Daewoo corruption scandal deepens, 2001). However, facilitation payments continue to be made the world over. How do these payments reflect in the eyes of the law Morally, facilitation payments, whether big or small, are wrong. But these payments are given and received in different and ambiguous ways and bypass the law. They may simply be given under the nomenclature of a gift or in the form of entertainment. International businesses have accepted it as a necessary evil. And it does appear that it is prospected to stay this way for a very long time to come (D'Ascenzo, Michael; 2008). By and large, in most countries, facilitation payments are tolerated if the sum involved is small. Nobody is inclined to run to the courts on small amounts spent on getting business. However, it is large facilitation amounts that can cause trouble. Large amounts not only cause legal hassles, they can even destabilize the concerned corporation. It is not healthy for large corporations to be paying out large facilitation amounts as these

Conducting a Literature Review Data Collection Essay

Conducting a Literature Review Data Collection - Essay Example For instance, the mothers’ smoking habit also increases the probability of ‘physician-diagnosed asthma and wheezing’ after first few years of birth. For instance, the unborn children in uterus were found vulnerable to asthma and adverse respiratory effects primarily because of maternal smoking. 1.2 – Maternal Smoking and Low Birth Weight Veiga & Wilder (2006) conducted an extensive research on maternal smoking habit during pregnancy among African – American and Caucasians in American society. The authors actually based their research on previous findings of 180 – 200 gm weight deficit among new born children whose mothers smoke during pregnancy. Their new research results augmented the weight losses as the researcher revealed that maternal smoking is noxious for health of unborn children and that the smoking causes weight loss of 200 – 230 gm. For instance, the probability of low birth delivery (LBD) among smoking mothers during pregnan cy is twice than that of non-smoking women. In addition, the demographic factors such as race, marital status, age, education and income level also impact the results since greater percentage of LBDs had been recorded among Caucasians in comparison to Afro – American women.

CHARACTER TRANSFORMATIONS IN FILM STORIES Essay Example | Topics and Well Written Essays - 250 words

CHARACTER TRANSFORMATIONS IN FILM STORIES - Essay Example The Long Kiss Goodnight does not really involve an occasion or event; rather it is just a positive change in this character’s life. "Back when we first met you were all like oh phooey I burned the darn muffins. Now, you go into a bar and ten minutes later sailors come running out" (The long kiss goodnight). This line from the film, The Long Kiss Goodnight, spoken by Samuel L. Jackson’s character, Mitch Henessey, perfectly summarizes the character transformation made by Geena Davis’ character from Samantha Caine back to Charly Baltimore. As Charly Baltimore, Davis’ character was originally a top-secret agent working for the United States’ Government. After suffering from Amnesia, she transforms into Samantha Caine, a suburban housewife, and beloved member of the Parent Teacher Association (PTA) at her eight-year-old daughter, Caitlin’s school. However, her memories slowly begin to return to her while chopping vegetables during preparation of her family’s dinner one night. At first she thinks she may have been a chef, due to her above average knife skills. She is forced to learn that she was not a chef, but a lethal assassin, when characters from her past begin to seek her out to kill her. Character transformation films are an interesting genre. While generally somewhat predictable, the viewer has seen the â€Å"Ugly Duckling† story repeated in various forms throughout cinematic history, this film’s transformation did not wholly fit the typical mold. ‘Transformation movies’ 2005, Characteristics of transformation movies, viewed 10 December 2011,

Absolute and Comparative Advantage Essay Example for Free

Absolute and Comparative Advantage Essay An individual, a firm, a region, or a county may develop an area of specialization naturally, but frequently choices must be made to determine what to produce for exchange or trade. Producers should concentrate on the activity in which the)- have an absolute advantage. An absolute advantage is the ability to product a good or service using fewer resources than other producers use. In the United States, this situation occurs when one region of a country is more suited than another for producing certain pro ¬ducts. Florida can grow oranges using fewer resources than Iowa, where heated green ¬houses would be necessary. Iowa has vast, flat acreage and can produce corn much more efficiently than could Florida. Thus, Florida specializes in oranges while Iowa concentrates on com. and the products are exchanged through the marketplace. When each of two parties has an absolute advantage over the other in producing a particular good or service, it is easy for both to decide their areas of specialization. But what happens when one party can produce both goods and services more effi ¬ciently than a second party? Should the party with the absolute advantage produce both products for itself? Although this party has the advantage in producing cither good, it should specialize in producing the good in which it has a comparative advantage. Comparative advantage is the ability to produce a good or service at a lower opportunity cost than other producers facc. 1’his means lerting the other party produce the good in which it has the lower opportunity cost. Total output will be greater, and exchange will allow both parties to have both goods. Suppose a woman can make $100 per hour as a marketing consultant. Part of her work includes preparing reports for her clients. Suppose that in addition to being a first-class consultant, she is more efficient at word processing than anyone she might hire to key the reports. Thus, she might be able to key in one hour what it takes an assistant two hours to do. As a result, she reasons that, instead of hiring an assistant to do the work, she should do it herself. Is she right to do her own keying as well as consulting? If she docs her own keying, she still must take an hour each day from her consulting to do so. The opportunity cost of keying is the S100 she could have earned consulting. The opportunity cost of consulting is the S20 she must pay an assistant to key the reports. Therefore, if she hires an assistant, she can devote her hill time or consulting. I led gross earnings will be $ 100 greater per day. After paying the assistant $20 for two hours work, she will still have additional net income of $80 per day. Thus, the marketing consultant is bcucr-off specializing full time in the service for which she has the greater comparative advantage.
