Public Transportation Essay Example for Free

Public Transportation Essay Public Transportation there are many kinds of commuters on public transportation: there are bus commuters, train commuters, and plain commuters. The first kind of commuter are people who ride the bus. At some point in their lifetime, everyone has had to ride the bus. Children ride the bus to school on a daily basis all the way through adolescence. People who live in large cities, ride the bus just about everywhere they need to go. Local buses bring in large amounts of money for their area and can be very helpful to the people of the town. The second facet of transportation would be the train system. Among the many classifications of train systems, there are subways, trolleys, and rail ways. Subways are utilized by people who live in large areas. Trolleys are used by people who live in smaller areas, like suburbs. Rail ways, broken up in rail roads, are used all across the nation. Rail road cars, drive on train tracks, and have become so popular that collectible toys have even been made after them. Rail ways help transport many of our nations most important goods, and without them we would be facing serious problems. The third type of transportation are airplanes. Air planes are mostly used for long distance traveling. Air planes are the most expensive of the three types, but they are still used very often. The wealthy often use air planes as their main way of traveling. Air planes can be seen by some as dangerous and very risky because of their bad history in the past. Air planes are high flying machines that carry people from city to city and sometimes even across countries. Air planes are used by people in politics, the millitary, and even regular citizens. Air planes are very important to our country and help make our lives much easier. As you can see, there are many diffrent types of transportation, but they all help make our lives easier in their own special way.

Cadmium :: essays research papers fc

Cadmium, symbol, Cd, is a silvery white metallic chemical element with a faint blue tinge to it. It is the fifty-seventh most commonly found element in the earth. It was discovered by F. Stromeyer, in 1817, in Germany. Stromeyer was studying a sample of zinc carbonate which separated into a the new element ultimately called cadmium. The only cadmium materials, greenockite (cadmium sulfide) and otavile (cadmium carbonate) are found in zinc oxide and zinc carbonate. Cadmium, which is usually associated with zinc has some differences; some of which are that cadmium is softer and has a lower melting and boiling point than zinc. There are five basic states of cadmium. First, there is the regular raw metal cadmium. Then there is cadmium oxide which is formed by burning the raw metal in the air producing brown smoke. Cadmium oxide can also be formed by heating cadmium carbonate in acid or ammonia producing a brown powder. By doing this, cadmium and oxygen are being mixed. Cadmium carbonate is made by absorbing carbon dioxide into the raw metal or mixing cadmium salts with ammonium carbonate, forming a salt-like substance. Cadmium sulfide is made by mixing hydrogen sulfide with a solution of cadmium ions, resulting in a range of colors from lemon yellow to a deep red. Cadmium halides are compounds with complex cadmium ions in them to form varied structure solutions. The regular structure of a cadmium atom is that it has four electron shells with a total of 48 electrons in it. The main use for cadmium is to plate iron, steel and other metals, protecting them from corrosion. This method has been used since 1919. The use of cadmium has to be limited because it gives off large numbers of toxins into the environment. The use of cadmium has gradually decreased in order to help the environment. It is not used to plate food processing parts or ovens because of this. Cadmium may be found in some cereals, nuts and vegetables, but scientists doubt that, if taken is small quantities, it would prove harmful. Cadmium is also used for nickel-cadmium batteries and nuclear control rods. It is used in compounds, for example, with copper to harden them. Since the color of cadmium sulfide varies it is useful for

Concept Of Culture And Organizational Analysis - 1269 Words

3.0 LITRATURE REVIEW 3.1 Concept of culture and organizational analysis: The concept of culture has been linked increasingly with the study of organisation (Graves and Rouse, 1990). Nevertheless, Organisational culture is a set of beliefs, values, and norms, together with symbols like dramatized events and personalities, which represents the unique character of an organization, and provides the context for action in it and by it (Deshpande and Webster, 1989; Ravasi and Schultz, 2006; Xiaoming and Junchen, 2012). In other words, these organizational values in turn form out the standard norms and guidelines for the organization that makes it distinct from others (Van Maanen 1979). Schein (2004), stated that functionalist believes that†¦show more content†¦Finally, many definitions imply that organizational culture is multidimensional and multileveled and includes many cognitive and symbolic strata. Hofstede (1980) framework for analyzing organizational culture mentions two different types-dimensions of organizational culture: Individualism and Collectivism, which are likely to influence the process of employees’ social categorization. Individualistic organizational cultures focus on and reward employees’ personal accomplishments, individual characteristics and abilities. This dimension is rather flexible, as employees are allowed and encouraged to behave in their own personal way (Chatman et al. 1998). Therefore, organizational membership is not salient and personality traits are appreciated. As Markus and Kitayama (1991) argued that individuals maintain their independence from others by attending to the self and by discovering and expre ssing their unique inner attributes. Collectivistic organizational cultures, on the other hand functionalist,belives that the general agreement of acceptable actions and behaviors, which assure shared objectives, interchangeable interests and commonalities among employees(Minkov and Hofstede 2011).functionalist believes that main priority of collectivistic cultures is independence and cooperation and that organizationalShow MoreRelatedOrganizational Culture Within A Hospital Setting1693 Words   |  7 Pagesregarding Organizational Culture as it relates to corporate business.
