T-Test

...T-test: Salaries of Female and Male Human Resource Managers Christy Newman Argosy University T-test: Salaries of Female and Male Human Resource Managers An independent-samples t-test using the raw measurement data presented was completed to check the difference, if any, of the salaries between female and male human resource managers, t(18) = -0.408, p = 0.688, but no significant difference was found (Female Mean = 62.2; Male Mean = 63.7). The preparation for a statistical analysis test began with a well-developed, clear research question: What is the difference, if any, between the salaries of female and male HR Directors? Next, the null and alternative hypotheses must be defined. The null H₀ is that the salaries of female human resource managers = salaries of male human resource managers. The alternative Ha is that salaries of female human resource managers ≠ salaries of male human resource managers. The next step in the process is to determine the appropriate statistical test and sampling distribution. Since σ is unknown and the number of salaries being tested is less than 100, the t-test will be used. Because we are comparing data from two different groups, the two-sample t-test will be used. We do not know if the variance is different or equal, so we will use the two-tailed t-test for two-sample assuming unequal variances. Subsequently, we have to choose the Type 1 Error rate. For this t-test, α = 0.05, which is the standard rate used by statisticians for......

Edward T.

...Edward T. Hall : Cultural Dimension Introduction „A fish only realizes it needs water to live when it is no longer swimming in the water. Our culture is to us like water to the fish. We live and breathe through our culture." As Trompenaar's quote outlines, culture is a crucial part of someone's life or even indispensable for the life of humans. This is because culture determines a human's basic assumptions, values, norms and belief systems as well as a human's behaviour, language, food, drinking habits and other determinants of one's daily routine. Understanding his or her own culture is a key factor in order to live in his or her society, but understanding other cultures gives the opportunity to look out of the box. It provides someone, for example, with the ability to interact between two cultures. A vital aspect when it comes to make business upon international terms. This paper will focus on the discoveries of Edward T. Hall and will also provide especially european countries as examples. 2. Hall’s dimensions of culture Edward T. Hall, Anthropologist, developed a culture model with three dimensions. Context, the most popular dimension, Time and Space. The following paragraphs will outline and explain the three dimension.

Mode T

...The Model T was more than just an ordinary car. It made history and that’s what changed the world forever. The man that was behind this amazing concept was Henry Ford. He was a revolutionary businessman that believed in his self and often quoted, “I will build a motorcar for the great multitude.” Ford had brilliant ideas with different techniques that transformed millions of people still to this day. Ford impacted America in three major ways the assembly lines, workforce and economic growth. In 1908 he moved his assembly line to the Piquette Avenue Plant located in Highland Park, Michigan. The first production assembled at this plant was the Model T vehicles. Through interchangeable parts, standard manufacturing and a division labor, the demand greatly increased for the Model T vehicle. Ford ran into a problem, the production of these cars took 12 hour and 8 minutes. He quickly turned that time around because of high demands and it only took 1 hour and 33 minutes for production. Ford was known as the man who put the world on wheels. He produced more cars than any other manufacturing combined together. It forever changed our automotive workforce. Ford discussed his innovation techniques which were to share his profit with the workers and pay them five dollars a day. He knew this would double the wage of any other manufacturing company and everyone would want to work for him. Ford reduced a typical workday of nine hours to eight hours to create three different shifts.......

Model T

...for the individual to run and care for. It will be constructed of the best material,
by the best men to be hired, after the simplest designs that modern engineering can devise. But it will be so low in price that no man making a good salary will be unable to own one – and enjoy with his family the blessing of hours of pleasure in God’s great open spaces.” – Henry Ford One of the most impactful innovations in American history was in, 1913, when Henry Ford’s Ford Motor Company introduced the Ford Model T. The Model T was the first automobile that was constructed on an assembly line. What makes the Model T revolutionary, however, is that it was the first automobile that was affordable to the general public. Before the Model T, automobiles were considered a high luxury item that only the rich could afford. However, using the idea of an assembly line with interchangeable parts, which he perfected, he was able to drastically reduce the time and expense required to construct a Model T. He then transferred those savings on to his customers, which revolutionized the automobile industry. Through the use of Ford’s method, which took the assembly line idea and the added conveyor belts, he was able to realize his dream to make a car for the ordinary man, while also changing the way cars were manufactured for generations to...

T, S.Elliot

...Eliot regarded Four Quartets as his masterpiece and it is the work that led to his being awarded the Nobel Prize in Literature. It consists of four long poems, each first published separately: Burnt Norton (1936), East Coker (1940), The Dry Salvages (1941) and Little Giddings (1942). Each has five sections. Although they resist easy characterization, each begins with a rumination on the geographical location of its title, and each meditates on the nature of time in some important respect—theological, historical, physical—and its relation to the human condition. Each poem is associated with one of the four classical elements air, earth, water, and fire.Outline Research Paper Thesis Statement: T.S. Eliot wrote poems that expressed his negative views of life, the human race, and the world around him by personifying" I’m not sure what this means: "comparing and highlighting the negative facts about them.

Booker T. and W.E.B

...The poem “Booker T. and W.E.B.” by Dudley Randall discussed the different life philosophies of Booker T. Washington and W.E.B. Du Bois. Their life experiences were similar yet contrasted on many levels. Washington had known nothing but hard work from an early age and he also knew that if anyone was going to get him out of the salt furnaces, it was going to be himself. Du Bois also knew a life of hard work, but unlike Washington, he had little help from outside sources and knew that if he wanted to be in a better place it was going to take a combined effort from many people to help him. This initial life experience also helped define their ideologies. Washington believed very much in helping yourself to get where you needed to be. Who else could help you better than yourself was the common thought in his ideal. Du Bois belief was more of a socialist take that focused on a community helping others so “we” all can be in a better place. Washington helped the African-American population at that time believe in themselves by working for their dream. When he was a principal at Tuskegee, he taught academics in addition to trades so the students would never be uneducated in anything. He drilled the ideas of saving and accumulating wealth, overall work on yourself first, before you strive to help everyone (i.e. gaining civil liberties). Du Bois also helped the African-American population at the time too. He was more vocal about gaining rights and freedoms than wealth....

Injection of T Cells

...TC cells or T cytotoxic cells have the ability to recognize kill target cells that are nonself. These target cells are self-cells that have been altered by infection with a pathogen, especially viruses such as Hepatitis B. They carry parts of endogenous antigens on its surface and are synthesized within a cell. More so, a normal cell will not trigger a response by a CTL but a virus infected cell produces abnormal endogenous antigens. The abnormal antigen attaches to the surface of the cell. In its attack, a CTL binds to the target cell and releases perforin. As a result the CTL induces destruction of the virus-infected cell by programmed cell death. 2. A patient with AIDS has a low TH cell count. Why does this patient have trouble making antibodies? How does this patient make any antibodies? Patients with AIDS have a low TH cell count because their immune system is being attacked on a constant basis. “This virus however, can also infect other cells, which include macrophages and certain other kinds of cells, which can engulf substances through a process known as phagocytosis. As a consequence of the interaction with CD4 on helper T-cells, HIV specifically infects the very cells necessary to activate both B-cell and cytotoxic T-cell immune responses. Without helper T-cells, the body cannot make antibodies properly, nor can infected cells containing HIV (an intracellular pathogen) be properly eliminated. Consequently, the virus can: multiply, kill the helper T-cell in......

Booker T Washigton

...Booker T. Washington was born into slavery in Virginia, and after the Civil War worked in a coal mine and peregrination to school at night. Education was consequential to him, but he withal apperceive that blacks in the South had very little power: little maxima, few rights, and despite the 15th Amendment, were unable to vote. His suggestion, which he made most eminently in Atlanta and became known as the Atlanta Compromise, was that blacks get jobs in blue collar craft work and farming and edifying, which were relatively lower paying jobs. He pushed for the engenderment of agricultural and technical schools, such as Tuskegee Institute in Alabama, which he founded. But by working strenuously and earning veneration, and accepting their inferior licit status for the time being, blacks would ultimately gain the reverence of whites, who would grant them more rights and sanction them to move up the economic ladder. This made Washington very popular with whites at that time, and he was even invited to dine at the White House with Teddy Roosevelt. However, in the next decades, in many ways, Washington was visually perceived as an obstruction to the civil rights kinetics, with his accentuation on slow economic gain, not pushing for rights and accommodation to the whites. While Washington was very authentic and understood the situation for blacks in the South at that time, later people visually perceived him as too inclined to compromise and keep his people down.
