The Plasma Membrane essays

The Plasma Membrane essays The plasma membrane consists of 40 percent of lipid molecules and 60 percent of proteins. It plays a very important role in living organisms, in which one of its main functions is to act as a barrier between the internal and the external environment of each cell. Not only that, but it also controls the chemical reactions of a cell. In 1935, Davson and Danielli suggested that 40 percent of the lipid molecules are arranged in a lipid bilayer. Each phospholipid molecule consists of a glycerol molecule linked to two long chain fatty acids and a phosphate group or phosphate head. The lipid bilayer forms due to the hydrophobic and the hydrophilic nature of the phospholipid. The polar head or phosphate group is hydrophilic or water loving and the two fatty acid tails are hydrophobic, or water hating. The bilayer is therefore arranged in order for the fatty acids to exclude as much water as possible their structure. With improvements in technology (improvements in electron microscopy), a more detailed structure of the cell plasma membrane was laid out. The two scientists, in 1972, by the name of Singer and Nicolson, suggested that the membrane is a fluid structure and is always moving. They put forward the idea of the fluid mosaic model of the membrane. This suggests that there is a lipid bilayer, however, apart from that there is a mosaic or an irregular distribution of different sized proteins that span the membrane as well. There are three different types of proteins that span the cell surface membrane. The first one is the extrinsic protein. This protein is situated only on one side of the membrane. The intrinsic proteins or channel proteins span the whole membrane, covering both the sides of it. The third protein is the Glycoprotein. This protein has a different structure compared to the i...

The effect of culture in International Marketing Essay

The effect of culture in International Marketing - Essay Example It is known that culture has a profound influence on peoples’ lifestyles, their preferences & tastes; this is important knowledge for marketing managers as tastes greatly affect purchasing behavior and trends. In addition, the nation’s attitude toward culture would impact on consumers’ behaviour, consumers’ lifestyle and beliefs. Therefore the power of culture causes consumption lifestyle among society. Hofstede and Trompenaars indicated that there is a level of cultural influence to purchasing around most of the countries, and an understanding of consumption practices can be made if the key attributes cultural influences are well known. As mentioned above, internationalization is closely associated with the standards of products, and this is in turn associated with proper coordination and execution of functions in the firm’s quality departments. The internationalization process of organizations is demonstrated by universal exchange theories. Considerations for internationalization are divided into two categories i.e. macroeconomic and microeconomic theories. (Dierkes 1999). Microeconomic scholars like Levitt, Ohmae, Howl, and Vernon have studied and written a lot on what inspires many organizations to strive so that they can achieve international recognition in terms of product ranges and market presence. The answer to internationalization practice by many firms is found in macroeconomic theories. The theories are concerned with and consider mostly on what factors and considerations inform many firms’ decisions to go international. The international product life cycle (IPLC) theories from Raymond Vernon (1966) explain the distribution methodology of companies’ expansion across national boundaries. The theory shows that many product lines are in the first place produced and processed in certain nations with the target of being sold on the international market. It very well and

Factor effecting staff turnover in hsbc call centre(uk)and how it is effected & related with job satisfaction of employee - Essay Example To improve the competitive position, banks used cost-cutting weapons. They streamlined their processes, shifted back-office operations, boosted workforce productivity and tried to use as much as information technology as possible. Banks rate managing customer experience as the most important factor of success (Wisskirchen et al., 2006). Call centers are expected to give them this competitive edge. Call centers are the perfect embodiment of the ‘new’ service oriented economy (Moriset, 2004). Call centers use the latest technology and thus enable a day’s work to be done in an hour. These employees are often compared to the workers on the shop floor of a manufacturing unit. Call centers in any nation follow the same technique and have the same attributes. They usually have very flat management structures which provide very little scope for career advancement. Job satisfaction is call centers is very low which accounts for attrition and high turnover in the industry. There is a strong relationship between job satisfaction and staff turnover. If employees are satisfied and their needs are met, it can limit staff turnover. Job satisfaction has been defined as an attitudinal state which reflects all the affective feelings that a person has about the job, cite Biggs and Swailes (2006). This includes growth, pay, co-workers and supervisors that contribute towards satisfaction in varying degrees. The level of satisfaction differs across permanent workers and the agency workers. Many call centers appoint agency workers so that the parent employer does not have the responsibility of the staff. Permanent employees become de-motivated when their organization uses agency staff but agency workers are used to prevent layoffs and their commitment to organization is much lower than the permanent employees. Maslow’s Hierarchy of Needs suggests that the basic physiological needs have to be met first before a person can look ahead. Only when the basic needs are

The Sanctuary Essay Example for Free

The Sanctuary Essay The author of the publication is Elif Batuman. The article’s title is the Sanctuary published in December 19th to 26th in the year 2011. The origin version title is the Life and the Legend by Susan Orlean. It was about the world’s oldest temple built 11,500 years ago at Gobekli Tepe in Turkey. Batuman embarks on a pilgrimage to the Gobelki Tepe temple where she finds much ancient memoirs concerning the way of life of the Neolithic man. She tries to analyse the Neolithic man, but her experience is quite captivating to the reader. The explanations that Batuman offers to regard the different remnants of the Neolithic man are quite convincing. She offers both scientific and biblical explanations for the existence of the evidence as presented by the remnants of the Neolithic man. Batuman has many questions regarding the way of life of the people who lived during the era. In her quest to seek a broader understanding and the way of life and origin of these people; she visits the excavation site where archaeologists are trying hard to unearth the finer details of the Neolithic man existence. There are many artefacts that she finds intriguing and has many questions concerning the animals and human sculptures that exist in the cave. She further tries to gather information from the local residents and raise questions to students and observes every detail and tries to analyse the situation in a logical manner. Batuman feels that these sculptures must surely represent the way of life and the thoughts of the Neolithic man but figures out that the Neolithic man must have had a connection with the Christian biblical origin of man. Batuman further cites many examples about the people from the bible like Adam and Eve, Abraham who are believed to have been among the first generations of mankind on earth. The remnants that are being unearthed from Gobelki Tepe are quite scary to an observer. Snakes, scorpions and other wild animals are naturally dangerous but were part of the creation that the Neolithic man had to contend with. Batuman feels that the men who had their penises exposed were trying to show the importance of children and that they were fertile. Towards the end of the story, Batuman says that Abraham wanted children in order for them to assure him of the continuity of the generation. Batuman tries to convince the reader by providing reasons as to why the Neolithic man became extinct. She feels that there were chances of an occurrence of a natural calamity that wiped out the Neolithic generation. The fact that people lived together with animals could have contributed to a disease outbreak or a natural calamity that wiped out the generation. Batuman further trusts her instincts that she is most likely to be a descendant of the large Neolithic man who is preserved in the museum. This can be somehow convincing to the reader because, sometimes human beings have been proven to have instincts, which guide them to some important discoveries. Elif Batuman tries to relate the Gobelki Tepe temple to the sacred nature of the Neolithic man. The man had a reference for a supreme being who was in control of mankind. The supreme God was recognized for his providence to the people. Among the fundamental things provided were children and food. However, she admits that the sculptures of animals may have been made in order to display a different message altogether. Batuman feels that the hunters should have done some sculptures or paintings in the caves that show hunting scenes. The message that the Neolithic man was trying to put across therefore may need further research in order to try and determine what the real meaning of the sculptures and animals could be.
