De-oxy-ribonuclease enzyme - Research Paper Example Proteins play critical roles in the cell, a factor that has helped scientists appreciate the salient significance of these molecules. Some cell proteins serve as enzymes, a role that involves the catalysis of all cellular processes. Proteins exhibit a high level of specialization, a factor that is evident in the structure and function of enzymes in the cell. Moreover, depending on the functions, proteins exhibit diverse structural adaptations. The role played by enzymes cannot receive any form of underestimation because cells would be unable to run processes at the required speed, and this would retard growth processes (Petsko&Ringe, 2004). Otherproteins are structural and include keratin, silk, ligaments, and tendons. There is also evidence that proteins are of significant use as contractile molecules. In, addition, proteins play a critical role in the immunes system as antibodies that recognize antigens and work towards eliminating them. Proteins are also critical in cell transport . Cells interactions and processes require signal both signal molecules and receptors, and biologists have identified such critical molecules as proteins. Structure of Proteins Proteins exhibit four different levels of their structure. It is worth noting that the basic components of proteins are amino acids. Scientists have described the existence of twenty different amino acids that are critical in building the wide range of proteins that perform the functions described above. The order and number of the amino acids making up each protein depend on the role played by each protein. Moreover, there is variation of protein structure across different species (Rigden, 2009). The simplest level of protein structure is the primary structure defined by its linear sequence of all the amino acids making up a certain protein, listed in three letter word abbreviations. This being the simplest form of any protein helps in highlighting the individual amino acids making up each chain. Usually, th e linkage between these amino acids is through covalent bonds that define the peptide bond existing between the amino acids. The second level of protein structure is the secondary structure characterized by the formation of regular structures that biochemists have described as helices and beta sheets. Hydrogen bonds facilitate the formation of such regular structures within the lengthy polypeptide chains of amino acids (Buxbaum, 2007. The hydrogen bonds only occur between carbon and oxygen molecules and between hygrogen and nitrogen molecules. Helices have been described as loose coils of amino acids with each turn consisting of three amino acid residues and additional atoms from the next amino acid. The coiling in alpha helices occurs in a clockwise direction. On the other hand, beta sheets have polypeptide chains folded in a manner that makes the regular structures be enjoined alongside each other. The third level of the protein structure is a three dimensional representation of a ll the polypeptide chains and other secondary structures. The structure remains in place because of ionic interactions, hydrogen bonds, sulfur bridges, and van der waals forces. The fourth level of structure is the quaternary structure defined by a specific complex shape taken by the different polypeptide chains with different forces holding up the structure (Whitford, 2005). Figure one Levels of Protein Structure De-oxy-ribonuclease This is one of the critical enzymes found in both higher

In what specific ways do you plan to think or live differently or to Essay

In what specific ways do you plan to think or live differently or to carry out your personal or professional roles differently a - Essay Example But these are also the lessons that are learnt from anthropology. Anthropology is the science of mankind. Anthropology can be considered a consequential effect of age of exploration. In the 17th century it started developing when the Europeans started interacting with the natives of their colonies. In the beginning this was used to understand and manipulate the natives so that they can become submissive slaves. It was also used to trace their descent. However, in the 18th century, Renaissance brought an enlightening phase for anthropology. Thinkers started talking of equality. Anthropology evolved for the better and became perhaps the most important discipline. Since Renaissance, anthropology has been trying to establish how despite apparent differences, all human beings are the same. It helps people see beyond these differences and also in tackling problems that arise from these differences. So whenever people are coexisting with differences, anthropology is needed. That is why it w as a need of age of exploration. This is what it is happening even now and will continue to happen. It helps in interaction when there is diversity by avoiding friction due to lack of understanding of others. Even today, humans are dependent on it even though it has been said that we are living in a time when the world has acquired an almost common culture. It remains important because each individual is very different from the other one. Even identical twins are different. They learn how to interact with the members of the society and even with each other gradually. They are aided in this by their mother or other mature people. The guidelines that she is giving are some of the lessons we learn from anthropology. So it is safe to say that anthropology makes bridges and is needed by everyone. In addition to that, it also teaches you how to cross that bridge. It does this not by burdening you with weighty theories or laws. Instead it tells you what you should expect. It makes you matu re. You become intellectually independent when you are able to think of possibilities. In simple words, it means that anthropology has made the initiation and the process of socialization very smooth and easy. There is no cost of it for example the person does not have to think critically or repetitively. Instead, anthropology has done something opposite and comes with a fringe benefit. It has granted freedom by maturing people. They do not have to be studious or calculating but just a bit considerate. Anthropology can judged to be superior to all social sciences. Social sciences include sociology, psychology, politics, economics, history, geography and cultural studies. All these subjects try to explain aspects of human nature or behavior using one frame only. They are not deep at all. Anthropology is better than all these because it has a thorough and holistic approach. It seeks to study, understand and explain a phenomenon with respect to all the aspects. Out of all these aspects , there is special emphasis on culture. It is because nothing is contained in a vacuum. However all the social sciences ignore this crucial aspect. They have a narrow base. They just have rigid theories which are only applicable in utopia. Utopia does not

However, this too has its positives and negatives. Both aspects will be discussed in the following sections so that an understanding of the employment relations within non-union forms can be sought and an in-depth study shall provide the basis of comprehension of a number of different facets – all of which come under the aegis of employment relations. When considering employment relations there are certain implications for managers that they must consider when coming up with the policy for dealing with employee issues. The three most important factors that need to be considered are the public, the employer and employee. The functioning of the company is largely dependent upon the maintenance of fair, friendly, and mutually satisfactory employment relations and the availability of suitable machinery for the peaceful adjustment of whatever controversies may arise. The term non-union is defined as the employees or w orkers of an organization â€Å"not belonging or relating to a labor union†1. This type of company reduces the impact of collective bargaining where the company is more inclined to deal with the issues of the employees on a one to one basis (Boeri 2001). The advantages of this sort of system are more individual attention to grieved employees, which will increase their levels of motivation. It also means more company ownership by all levels of the workers who take pride in solving problems for the betterment of the company. Lastly, the monetary benefits for the company, who do not have to pay the dues of the unions and are more economically strong and can, improve their bottom line (Gannon 1987). There are also many other smaller advantages and disadvantages however they are beyond the scope of this paper. Most managers are of the opinion that the most important aspect of good employment relations are affective negotiations.Communication is the glue that makes policies real an d without which they are ineffective. The fact that communication is necessarily a two-way process, involving dialogue rather than simply instruction, is well established (Morley 2006).

The qualities required include focusing on positive behaviors and outcomes, taking a positive, problem-solving approach, anticipating problems, recommending solutions and being able to offer sound advice to senior managers about implementation. Negotiating skills are still useful but needed less often.

Investing in Human Capital Coursework Example | Topics and Well Written Essays - 1000 words

Investing in Human Capital - Coursework Example Employees are seen as assets current and future value which can be improved through investing resources on them, especially knowledge. Organizations which upholds these practices always communicate to their employee on a regular basis.   The practice of employee’s security is the one that is surprising. The business world is rapidly changing and companies are embracing policies that not only affect the operations of the organization but also the employees. It is for this reason that employees need a guarantee that despite the internal changes that occur within a given organization will not affect them. If however they are affected negatively, then, the organization would be able to compensate them accordingly. Employee security takes place in many forms for instance, in manufacturing industries where employee are exposed to machines every day, there are risks involved. Some of them include the risk if being cut by machines, exposure to chemical compounds among other. The employer of such an organization must ensure that his employees have medical assurances and cover. This will motivate employees to keep working in spite of the unconducive working environment. This is because, in case of an accident, the company will be liable and they will not have to dig their pockets to cater for any medical expenditure. Employment status of an employee is also a security to them. During the time of economic booms, many companies employ a lot of people. On the other hand, during the recession, these organizations dismiss a lot of employees. This is discouraging and such organization ends up building bad image and this may lead to its collapse.

Cultural practices at high altitudes that affect reproduction and Essay

Cultural practices at high altitudes that affect reproduction and maturation. Specify what those things are - Essay Example Since earth is a globe with places of high and low altitudes the people surviving in high altitudes have to retain certain cultural practices to maintain their health quotient. Human beings highest priority at all time were to safeguard its own species and as a result reproduction and maturation always had upper hand in their life. â€Å"Generally High altitude residents engage in cultural practices that modify the effect of hypoxia on energy availability as well as other attributes of the high altitude environment†(Hornbeing,49).It is seen that people living in High altitude like Tibet, and Nepal practice many cultural practices which positively affected their reproduction and maturation level High altitudes lack oxygen which can result in degeneration of cells and affect the overall health of human being, certain cultural practices improved their living conditions. The culture practice of retreating to lower lands during pregnancy Human being is largely depended on their nat ural environment for survival and sustenance and irregularities in their environment can have a significant effect on his health and wellbeing. For human, the process of growth and development is a crucial issue, and every thing initiates with healthy reproduction and maturation of offspring. ... nt to which the high altitude climate can affect the fertility and maturation of an individual .Generally less malfunctions are noticed and this could be the effect of the cultural practices used by the indigenous people living in that specific region. As per (Russo)â€Å"Babies born to mothers living at high altitudes tend to be smaller than babies from lower altitudes. The reduced flow of oxygen to the placenta can slightly retard the baby's growth, and this can increase some of the risks to the baby (particularly if it is born prematurely)†.This could be a main reason the women move to lower altitude where oxygen is abundant that can assure a better health for the themselves and their unborn child Social aspect of moving to lower altitude for birth It is widely seen that Tibetan and Nepalese women descend to lower altitude during pregnancy to avoid the high altitude stress prevalent in cold regions. Tibetan and Nepalese people have unique adaptation capability in comparison to normal people and have better fertility rate than women of lower altitudes. However, they come to lower altitudes to avoid the morning sickness, nausea and other illnesses they confront during they times of pregnancy. Generally a deficiency of oxygen in the blood level can result in seizure, fatigue, coma or even death to women as she is in pregnancy stages. So in order to avoid these fatal conditions the women in high altitudes mostly move to lower altitudes to have a safe pregnancy period and healthy child. Every culture wants to protect their people and reproduction is the main source by which we populate and expand our generation. The women in the high altitudes realized that during pregnancy they experience high difficulty in breathing and they knew this could affect health and maturation

International Business Essay Q.2 a) Evaluate the different ways in which Bata has interacted with foreign political systems in its investments and operations abroad. ANS Multinational enterprises (MNEs) like Bata must operate in countries with different political and legal conditions, so the political impact on the foreign investments is very important. This paper explains this issue based on the Bata case in three parts. The first part evaluates the different ways in which Bata has interacted with foreign political systems in its investments and operations aboard. In the second part, the advantages and disadvantages, which MNEs bring to their company and the host-country when doing foreign direct investment, are analyzed relating to the Bata case. And the last part gives a detailed analysis of the complex political impact on international business with reference to the political environment in general; also supply the way of formulating effective political strategy. * Batas effective organizational structure and managing style With activities in 60 countries, Canada-based Bata Shoe Organization has much operational experience both in developed countries and developing countries and can deal with different political systems. It has an effective organization structure, which consists of  · Bata Limited located in Toronto, Canada, acts as headquarters of the operating companies. Regional offices exist in Toronto, Mexico City, Singapore, Paris, Calcutta and Harare.  · The International structure: a decentralized organization, where operating companies are independent businesses, supported by a global management team.  · Private Ownership: Bata shoe organization companies have also entered into a number of joint ventures, retail franchising and brand licensing agreements [1]. By and large Batas operations are independent units established in each country where the firm does business. As such, Bata is able to decentralize control of its politica l strategygiving subsidiaries significant autonomy in managing relations with their respective government. b) Should Pizza Hut put more of its efforts in expanding in Brazil or somewhere in South East Asia? Why? ANS – Pizza Hut, one of the most popular food chains, opened their 10000Th shops in the Brazilian market in 1994. Pizza Hut’s parent company is PepsiCo. PepsiCo was trying to penetrate in Brazilian market in various ways. However, the path was not as easy as assumed. Pizza Hut faced decline in the Brazilian market. Experts said that there were two probable reasons for this. One is Pizza Hut’s less successful introduction of new products and the second is the low price strategy of the competitors. However, Pizza Hut had a high hope to make Brazils their second or third major market because Brazil had many location specific advantages like urbanization, size, population, Gross National Product etc. Brazil endured erratic political situations since 1964. After a long military dictatorship, a stable political reformation was done by the year 1997.Economically; Brazil has a mixed history as well. It has a very good economic potential. It has access to several natural resources and well knit infrastructures. However, inflation affected the economy very badly. Pizza Hut entered in Brazil in 1988, during the period of high inflation. It followed the practice of corporate franchise. Later, Pizza Hut bought some of the franchises. But still different problems arose like- difference in cultures, cost of maintaining large pool of employees and of course inflation. Gradually, the inflation rate of Brazil normalized. People made more informed decisions and Pizza Hut began to flourish. However, in 1995, sales of Pizza Hut dropped. As a mean of counterattack, Pizza Hut took two different strategies. One was to cut the price by 25% and another was to announce various sales related decisions by mingling with local cultures like Samba dance. But both of the plans failed miserably. In these ways, Pizza Hut struggled to succeed in the Brazilian market. Q.3 a) what factors threaten India’s future competitive positions in cashew nut productions? ANS – Since the opening of China’s doors to world trade in the late 90’s, it has become an emerging super power. Hence, China may be a threat to India’s current competitive position in the cashew nut production because it is also capable to support cashew processing with its abundance of human resources, low-wage rates, and possible training in the manual dexterity required in the premium cashew nut production. China is currently engaging in new markets and providing cheap manual labor to other manufacturing. With this, China can see that the increasing profitable cashew nut industry and decide to enter it because it has the capability to do so. Moreover, the current formulation of the European Union (EU) provides that its members eliminate trade barriers for imports and exports between each other may be a possible threat to India’s United Kingdom market. Since the UK can virtually import anything from its neighboring countries without any cost, it might affect the demand of cashew nuts –the Europeans may divert their attention from cashew nuts to other products popular in its neighboring countries. India’s competitiveness could also be threatened by the increased Research and Development improvement that countries worldwide are engaging in nowadays. Brazilians (India’s most prominent competitor in the cashew nut industry) may possibly find machinery that can be substituted for the needed hand dexterity for the flavor that India’s cashew nut has. b) Should the United States seek to tighten the economic grip on cube? If so, how should it be done? ANS – U.S. should not seek to tighten economic grip on Cuba as it is already a weak economy as compared to U.S. due to the political environment of the country for the past few decades. For U.S. industries and companies Cuba is a very potential market. Also the workforce is efficient, so there is a possibility of efficient labor at lower cost for U.S. industries. Also, other countries of the world started favoring Cuba and also doubted the rationale of U.S. on imposing the embargo. 1. Attitude: An attitude may be defined as a learned disposition to behave in a consistently favourable or unfavourable way with respect to a given object (Schiffman and Kanuk, 2000). Stated differently, it positions people into a frame of mind of liking or disliking things, of moving toward or away from them‘ (Kolter and Armstrong, 2008: p144). It is acknowledged that people have attitudes toward almost everything religion, politics, clothes, music, food (Kotler, 2003). For instance The demand for life insurance in a country may be affected by the unique culture of the country to the extent that it affects the population‘s risk aversion (Douglas and Wildavski, 1982). Henderson and Milhouse (1987) argue that an individual‘s religion can provide an insight into the individual‘s behaviour; and understanding religion is an important component of understanding a nation‘s unique culture. Also, Zelizer (1979) notes that religion historically has provided a strong source of cultural opposition to life insurance as many religious people believe that a reliance on life insurance results from a distrust of God‘s protecting care. But historically, some form of social insurance existed in Nigerian and Africa society long before the introduction of the modern insurance in Nigeria (Osoka, 1992). These social schemes evolved through the existence of extended family system and social associations such as age grades, and other unions. The simplest form of the â€â€"social insurance‘ was practiced by means of providing cash donations, materials or sometimes organized collective labour to assist members of extended family and members of social or communal associations who suffer a mishap. 2. Lack of Knowledge of Insurance Culture: In a recent study of quality of life in developing countries with reference to South Africa (Moller, 2004), income and social security (own wages, ability to provide for family, insurance against illness/death and income in old age) have been treated as one of the major indicators of quality of life. This standpoint stresses the significance of insurance to human life. Ironically, insurance services seem not to have been so accepted enthusiastically in developing countries. The abysmal level of insurance culture in developing economies has attracted relative interests among researchers and practitioners alike. Risk has been identified as a central fact of life in the rural areas of less-developed countries (Udry, 1994). Some of the problems associated with this have been marketing. For example, Omar (2005) assesses consumers‘attitudes towards life insurance patronage in Nigeria and found out that there is lack of trust and confidence i n the insurance companies. Other major reason for this attitude is lack of knowledge about life insurance product. 3. Low Level of Education: Educational status of Nigerians has significant influence on their attitude towards insurance. Educated people have more positive attitude to insurance than less educated ones. In a recent insurance conducted in Lagos, Nigeria. The choice of Lagos is due to its nature as a metropolitan city where most Nigerian ethnic groups are largely represented. Fact shows that respondents with higher education outperformed others even though no statistical significant difference was observed with vocational education. 4. Unemployment Issue: Employees working status has a significance effect on Nigerians attitude towards insurance. Retired and Employed Nigerians with means attitude scores of 28.50 and 28.14 respectively outperformed their competitors. No significant difference was observed between retired, employed and Self-employed respondents. On the other hand, self-employed people have significantly higher attitude towards insurance than unemployed, student and part time workers. This result is quite similar to findings in most developed world. In Conclusion, The findings of this study suggest some major implications for marketing of insurances services in Nigerian businesses environment which is a big market. Given that attitude is strongly linked to behaviour, marketers of insurance services targeting Nigerians are confronted with the challenge of encouraging people to embrace insurance institution and its associated benefits. Based on the findings, this article confirms negative attitudes of Nigerians to insurance services further. But apart from this broad finding in respect of the negative attitudes to this line of business, this study suggests some specific findings based on different demographical factors of the respondents. The findings serve as inputs to marketers of insurance services on how they formulate and implement relevant marketing strategies towards addressing the nonchalant attitude of Nigerians to insurance. For instance, specific marketing strategies are required to encourage the young generation below 46 years of age, the divorced/separated, and the less-educated to embrace and appreciate the role of insurance. Since, the basic issue associated with this lack of interest rests mainly in their lack of appreciation of the roles of benefits of insurance services; it is recommended that significant marketing communication activities with instant compensation to both marketers be targeted more at this set of people highlighted. This will help to kindle their interest in the business and brings the insurance institution to the highly exalted position it belongs in their perception.
