Household understanding of Firewood logs as a renewable energy. Based Literature review

Household understanding of Firewood logs as a renewable energy. Based on the UK with a focus on Scotland - Literature review Example Production and use of wood fuel lead to the emission of carbon dioxide at different stages (Read et al 2009, pp 30-40). This is during harvesting, transportation and transportation of the wood fuel. The two are green house gases that have a green house effect to the earth. However, the same wood energy can be a source of renewable energy. Wood energy can be a source of renewable energy within the paradigm of specific conditions. The conditions include wood from the resources that are sufficiently sustainable, high calorific value and water content, gasification that cuts down on the level of emissions, and fiber content that allows the users to re-use or recycle the wood (Wilson & White 1986, pp20-40). Wood fuel has several environmental advantages that make it a choice over other fossil fuels. It is renewable and offers dependable supply (FAO 2010, pp 162). The amount of carbon dioxide emitted during the burning process is typically 90% less than when burning fossil fuels. Wood fuel contains minimal amounts of sculpture and heavy metals (McKay et al 2010, 1017-1027). The most notable part is the fact that is its particulate emissions, which are considerably controllable. Read, D.J, Freeer-Smith, P.H, Morison, J.I.L, Hanley, N., West,C.C. and Snowdon, P. 2009.

Children and Happiness Essay Example for Free

Children and Happiness Essay What makes children happy? ‘That’s easy, you might say, ‘a new toy, an ice cream or a trip to the amusement park.’ While these things bring an immediate smile to many children’s faces, they are probably not the things that will keep them happy day by day, or turn them into happy adults. The basic ingredients that make children happy during childhood seem to be the same ones that help them to become happy adults: a secure relationship with parents gives the base to confidently explore the world and develop a sense of mastery and recognition, all important components in the recipe for happiness. However, in the short term, the new toy might provide a smile too! Man has to pass through many stages of life, since he is born until he dies. He passes through infancy, childhood, boyhood, youth, middle age and old age. Childhood continues from the 6th to the 12th year of age. Boyhood continues from the 12th to the 19th year of age. Youth lasts from the 20th to 35th year of age. Middle age lasts from the 36th to the 55th year of age. Old age continues from 56th year until death. Of all the stages of life childhood is the most important. Because it is the formative period of life. It is also the first conscious stage of life. Important of childhood: Childhood is the formative period of life. Human character takes its shape in childhood. Man gets deep and lasting impressions in his childhood. Because at this stage mens mind is soft, receptive and plastic. It is just like the potters clay. So human character should be properly shaped in childhood. What should be done in childhood: Childhood is one of the growing stage in mans life. The human beings grow up to 24th year of age. So, the health of the child should be properly looked after. He should be given balance diet. He should be encouraged to from healthy habits like early rising. He should be taught to be neat and clean, to do exercise regularly, to eat, sleep, read and play at habits. He should be kept happy and cheerful. All these will help him to grow healthy in body and mind. Proper and appropriate food should be provided to the childs mind. He should be given the most carefully chosen books to read. he should be given childrens magazines. He should be given interesting and instructive pictures. At this stage, records should be kept of the childs inclination, aptitude, knack, mood, temperament, interest, abilities and his latent qualities. On the basis of these records, the future of the child should be planned. The child should be trained on the basis of this plan. Care of parents and teachers: In the modern system of society and education in India, nobody takes the responsibility of the childs welfare. The parents think that it is a responsibility of the teachers, because the child stays in the school for six hours a day. The teachers think that it is the responsibility of the parents, because the children belong to their parents, and in future the children will come to any use only to their parents and families. But in the interest of society, nation, country and above all mankind all have responsibility for the welfare of the children. Conclusion: It is the foremost duty of the Government to see to the welfare of the children. But in India we find that a lot of children in schools are dying by food-poisoning in the Government Mid-day meal system. The school buildings are defectively constructed. So the buildings breakdown and many children die underneath. the milk-powder that comes to Panchayats and Block offices is said to be put to black-marketing. Government should look to all these affairs. Childhood is the most important period in a mens life. So, the Government should take utmost care of it.

Buy a Bride :: Marriage History Papers

Buy a Bride In the mid-eighteen hundreds the first waves of Americans began heading west. They were in search of the American dream; their chance to live happily ever after. This first wave of settlers was for the most part, composed of miners looking to strike it rich. They exploited the mineral resources all over the west, wherever gold was found; the most famous places were in California, Colorado, and the Dakotas. The brave and adventurous men streamed over the continent in wagon trains or around it in ships in order to reach the west coast. Towns sprang up around the different places where gold had been found as well as around places for ships to dock. The next wave of people to head west was the ranchers. They needed land and western land was far cheaper than land in the east. The ever growing cities in the east needed an ever increasing supply of food and the cattle found on the western plains proved a good and profitable solution. Shortly after the ranchers the farmers came looking for land. The land in the east was worn out from over cultivation, in stark contrast the western land was rich and virtually untouched, not to mention cheaper. The west was a new and promising land with endless possibilities. (Summitt) Despite the promise and possibilities there were a few minor problems. One such problem was that the vast majority of the settlers were men. "Men from the eastern states, Canada, and Europe often preceded the women, and then found themselves longing for feminine companionship." (Yalom 226) Population imbalances, combined with geographical isolation and physical distance, often made men frantic to find wives from among the few single Anglo women living in their region of the west. Unfortunately, interracial marriages were not looked upon favorably by the population at large, so even men who had taken Indian brides were looking for women of European decent (15) In some places the problem was worse than in others. In the Washington Territory it has been estimated that the ratio of men to women, regardless of marital status, as high as 9:1 and that there were at least two thousand men in the Territory that wished to get married (Holbrook 47). This problem was not a simple one to remedy. Men who had enough money traveled east and brought back a wife, but the vast majority of the populous did not have the capital needed to make such a journey possible.

The work of Langer & Rodin

To explore the effects of decision-making and responsibility on residents in a nursing home, Langer and Rodin gave residents a houseplant. Residents were to make all the decisions about when and how much to water and how much sun to give their plant. Resident in the experimental group were also given other choices such as where they would prefer to receive visitors, whether they wanted see the weekly movie and which evening they wanted to attend (a movie was played on Thursdays and replayed on Fridays), etc. A comparison (control) group were also given plants but told that the nurses would take care of them. Those in this group were not encouraged to make decisions for themselves but were told that staff was there to help them. Issues were as similar as possible with the experimental and comparison groups except for the distinctions about who was in control and responsible for decisions. The researchers used various behavioural and emotional measures to judge the effect of the encouragement, for example, participation in activities at the nursing home, how happy the residents felt and how alert and active the residents were. Clear and dramatic improvement was made in the group given more responsibility. Eighteen months after the study the researchers returned and again performed the outcome measures. The residents who had been given more responsibility were still significantly more active, vigorous and sociable than those in the comparison group. The experimental group also asked more questions during a lecture that Judith Rodin gave. During this return trip physical health was measured. Prior to the study the two groups had been in similar health based on their medical records. However, eighteen months later the health of the experimental group had improved while that of the comparison group had worsened. The most striking discovery was mortality rate. Only seven of the 47 residents in the experimental group had died whereas 13 of the 44 residents in the comparison group had died (15% versus 30%). These results have been confirmed by much research since the time of the original experiment. To improve this experiment they could have looked for other areas where choice can be given back to residents such as dining, bathing, and placement of personal items in their room. Record the outcomes. Watch to see if over time there are changes in activity participation, alertness and affect of residents. As this experiment proceeds it would be good for staff to discuss amongst themselves how to change their own perspective to maximize residents' sense of independence, freedom and involvement. The relation between health and a sense of control may grow stronger in old age. This could occur through three types of processes: experiences particularly relevant to control may increase markedly in old age; the association between control and some aspect of health may be altered by age; and age may influence the association between control and health-related behaviours or the seeking of medical care. Studies show that there are detrimental effects on the health of older people when their control of their activities is restricted; in contrast, interventions that enhance options for control by nursing home patients promote health. With increasing age, however, variability in preferred amounts of control also increases, and sometimes greater control over activities, circumstances, or health has negative consequences including stress, worry, and self-blame. Mechanisms mediating the control-health relation include feelings of stress, symptom labelling, changes in the neuroendocrine an d immune systems, and behaviour relevant to health maintenance. * Work which very clearly supports Langer & Rodin is that of Marmot et al (1997) and the study of civil service office workers: – Marmot et al (1997) Marmot and his co-workers devised an experiment to determine the association between adverse psychosocial characteristics at work and risk of coronary heart disease among male and female civil servants. There were self-report questionnaires provided for information on psychosocial factors of the work environment and coronary heart disease. Independent assessments of the work environment were obtained from personnel managers. Setting: London based office staff in 20 civil service departments. Subjects: 10308 civil servants aged 35-55 were examined-6895 men (67%) and 3413 women (33%). Results: Men and women with low job control, either self reported or independently assessed, have a higher risk of newly reported coronary heart disease during the follow up. Job control was assessed on two occasions three years apart, although intercorrelated, had cumulative effects in newly reported disease. Subjects with low job control on both occasions have an odds ratio for any coronary event of 95% compared with subjects with high job control at both occasions. This association could not be explained by employment grade, negative affectivity, or classic coronary risk factors. Job demands and social support at work were not related to the risk of coronary heart disease. Conclusion: Low control in the work environment is associated with an increased risk of future coronary heart disease among men and women employed in government offices. The cumulative effect of low job control assessed on two occasions indicates that giving employees more variety in tasks and a stronger say in decisions about work may decrease the risk of coronary heart disease. * Whereas the work done by Brady (1958) in the ‘Executive Monkey' experiment completely goes against Langer, Rodin and Marmot: – Brady tested groups of monkeys to determine which were the quickest learners; they would then be chosen to take the place of the ‘Executive Monkey'. The executive monkey is then sat in a harness with its feet touching the floor allowing almost complete mobility, the non-executive monkey is sat in the other harness so that it cannot touch the floor, both harnesses are connected to a bar that in turn is attached to a pivot. A bell would sound and the exec. Monkey would have 20 seconds to get to a switch, if he did not manage to get to the switch in time, both monkeys would be given an electric shock. Brady discovered that the best way to conduct this experiment was to put the monkeys 6 hours in then 6 hours off, this was found to be the best way to stress them. Around 23 days into the experiment the executive monkey would die from stomach ulcers, due to the stress. > We could argue that the monkey had the control over whether they got shocked or not and yet it still got stressed and died, which would then completely dis-prove Langer & Rodin. > But you could also argue that the exec. monkey got stressed from having to get to the switch and its also possible to say that the executive monkey didn't have complete control, i.e. they couldn't turn the electric shocks off completely, and so got stressed from having to continuously press the switch. * Weiss (1972) repeated Brady et al's experiment but with rats this time: – He found that giving feedback on successful shock avoidance (by sounding a tone) reduced ulceration in executives to below that of the non-executive rats. The feedback tells the animal it has avoided shocks and increases its ‘sense of control' over the situation. The non-executive animal cannot respond and lacks any control at all over what's going on, this leads to more ulceration. ==> By comparing Brady and Weiss' experiments it's very clear to see that the idea of a ‘sense of control' separates the two. Not as many animals will die in Weiss' as in Brady's, the rats don't feel as stressed as the monkeys because they feel more ‘in control'. These studies also show the importance of control and feedback on successful coping in reducing levels of stress.

Free Essays on Englands Colonization in North America

England’s Colonization in North America England’s colonization in North America first started in 1497. In 1497 John Cabot claimed the basis of England’s land in North America. The land that was claimed could not be colonized until the early 1600’s because of Spain’s control of ocean travel and trade. Spain was the powerhouse on the 16th century. It wasn’t until 1588 that England would start to consider colonization. Hostility existed between Spain and England over trade and colonization. On August 8th, 1588 English defeated Spain in the Spanish Armada. England was now able to think about colonization on the North American coastline. Two main companies would start the colonization to North America. These companies were the Plymouth Company and the London Company. The Plymouth Company was founded in 1606 by a group of puritanical people. The Plymouth companies head quarters were in Bristol, England. The Plymouth Company would need a charter to travel and colonize in North America. Charters were very hard to create and because of this the Plymouth Company purchased their charter from the Muscovey Company. The Muscovey had financed the trips of John Cabot.

Decolonization essays

Decolonization essays De-colonization began with the British colonists in the United States who declared independence in 1776. Most of Latin America gained independence a few decades later. De-colonization continued through the mid-1970s, mostly in Asia and Africa, until almost no European colonies remained. Most of the newly independent states have faced tremendous challenges and difficulties in the post-colonial era. The stability and harmony of de-colonized countries are not guaranteed once the countries are left to the hands of indigenous people. Colonies were flourishing under the colonial administrative government which creates bureaucratic, legislative and educative filters that guarantees indigenous interest. Through law, politics, policy and culture brought by colonizers, the indigenous reproduce themselves while legitimizing and rectifying their origins. Along with an adequate and appropriate government system, both colonial and indigenous realities can contribute to the future shape and nature of the nation state. Economic investment by the administrating power directly benefits the inhabitants of a given region (Guarini n.p.). Suitable structures in the field of credit and savings have been set up successfully in colonies and this has managed to organize and support the production of goods necessary to the economic equilibrium of the region. By meeting the demands of the people, a higher standard of living is achieved. All citizens benefit from security arrangements when the territories host colonial security forces (Plunkett n.p.). It is guaranteed that the colony will be protected by the armed forces available if there ever is a case of war. This is possible as every state has a right and obligation to defend its colonies (Cunningham n.p.). The people of a majority of the territories no longer view, if they ever did, the activities of foreign economic interest or the presence of military installations on their territory as detrimental to their...

Free Essays on Magpiety

The main idea of my essay is that the speaker in the poem â€Å"Magpiety† by Philip Levine has realized that half of his life has passed, yet he has not yet lived it. A part of my argument is that he feels that he has wasted half of his life because he is sixty-four looking back on thirty-two and wondering why he was rushing. One of the biggest problems that I had at this point in the writing process was that at first, I didn’t have enough evidence to support my thoughts. However, after revising several times, I found the evidence needed. Another problem I had was relating different sections in the poem to one another. There were many lines in the poem that could be interpreted in many different ways and I had to sift through and pick the best suited ones for my topic of argument. The point that I feel I have made successfully is that the man in the poem has not lived life to the fullest. The man noticed that his life was moving fast, and he tried to slow down but had an anxiety attack of some sort. Though we do not necessarily know what it is about, it can be interpreted in many different ways. The question that I would like answered from the reader is what they think about my use of evidence. As I said before, I had trouble coming up with evidence to support my thoughts, while strongly abiding to them. If I was going to start revising, I would focus on the magpie a little bit more, I would consider in depth how the last lines of the poem are significant, and I would go more into how the man hasn’t lived his life to the fullest....

"This I Believe" Essay Example | Topics and Well Written Essays - 500 words

"This I Believe" - Essay Example hen I was in elementary class fifth division I made a decision that I was going to start leading in my class although many people did not believe in me including my class teacher. Going as per my performance in previous exams nobody could believe that I could even manage to appear among the top ten. I had to put my faith into practice and demonstrate to everyone that nobody could limit me. When the results for the mid-term exams were released I was not the first but I was among the top five and I could see everyone could then believe that it was possible, from bottom ten to top ten. When we sat for the end of year exams I did it passionately with a lot of conviction in my heart that I could make it. When results were finally released it was not a surprise for me that I was named as the best student except for the few Doubting Thomases’s who had refused to believe in my hard work, commitment and dedication. I continued to lead in class right from the fifth division until when I completed the elementary education. When I joined high school competition became extremely high but I could still appear among the best because I continued to believe in myself. Some of my friends and relatives call me a go-getter while others say I am too aggressive but what I know is that nothing is impossible in world. I am a true believer of self-motivation and inner drive. Many a times people said negative things trying to discourage me from getting whatever I want in life but I have never listened to their discouragements instead I have continued to believe in what I know about myself. Holding on to my belief has not been easy. At times I may desire to achieve something that is beyond my ability. It then becomes a problem because it means I have to strain.

Declaration Essay Example | Topics and Well Written Essays - 750 words

Declaration - Essay Example ? was affected as a means of avoiding a schism that would necessarily diminished the overall level of support that the newly formed â€Å"United States† could engender from its southern states. From an analysis of the texts provided, it is clear and apparent that the reaction to the Declaration of Independence within the United States was not quite as it has been presented throughout successive American history courses. By and large, the Declaration of Independence went largely unnoticed and unheralded; due to the fact that bloodshed and hostility had already existed for the period of over a year between the British Empire and the colonial revolutionaries (Maier 3). As such, the overall impact of such a document was somewhat secondary to the realities of the strategic battles that were occurring within the colonies at the time. This is not to state that the Declaration of Independence was somehow unimportant; rather, with respect to the day-to-day life of the average American, the outcome of the war and the realities of the conflict were of much greater importance. Interestingly, the reaction to the Declaration of Independence throughout the world came in many different forms. For instance, European empires were fearful of the publication of the Declaration of Independence within their respective languages and/4 within their respective populations. This was obviously due to the fact that they feared that such a level of enlightenment thinking with regards to the innate and tacit rights of mankind would inspire similar acts of rebellion against their own assets throughout the world. However, notwithstanding this fact, the reaction to the enlightenment thinking of the Declaration of Independence spread rather quickly throughout (Armitage 31) Europe. It ultimately reached as far away as Warsaw within only a few months after its initial publication. By and large, the European response to the Declaration of Independence was one that was incredulous and curious with

The Effect of Taking Creatine Supplementation on Exercise Performance Essay

The Effect of Taking Creatine Supplementation on Exercise Performance - Essay Example The author of the essay "The Effect of Taking Creatine Supplementation on Exercise Performance" begins with the introduction of the topic. Creatine monohydrate (Cr) is marketed as ‘nature's muscle builder’ and ‘the most legitimate sports supplement around’. Professional and amateur athletes alike are taking this alleged ergogenic aid, hoping to increase their strength and performance. Cr supplementation is claimed to increase muscle power by playing a role in the transfer of energy to help the muscle contract. Thus, it has become one of the leading sport supplements used by strength power athletes today. Reports suggest that 48% of male collegiate athletes use or have used Cr during their preparation for competition. However, the prevalence of use among strength/power athletes is much greater, and is estimated to approach more than 80% in certain sports. Cr use has also gained popularity among high school athletes, with 90% of athletes who supplement using C r. It is clear Cr is highly used but the question remains whether it actually increases strength and power leading to an improvement in exercise performance. Also the widespread use of Cr in dietary supplements does not necessarily indicate safety or advocacy, thus there is a need to evaluate the safety of Cr. Although the role of creatine in human metabolism has been understood for over a half-century only recently has its potential as a sport ergogenic been explored. A considerable number of studies have been published subsequently.

In the case of indirect distribution, each of the intermediaries receives a product at a set price then he moves it to the next at a much higher price until the products reach the final consumers. In this regard, the price of the product rises considerably as it goes through these channels thereby becoming very expensive and unaffordable by the time it reaches the final consumer. For instance, coffee goes through a long winding channel before reaching the final consumer. It involves the farmers who grow the coffee, the exporter who exports processed coffee from its country of production to overseas, the importer in overseas who orders coffee from coffee producing regions, the distributor of imported coffee such as supermarkets and stores, and finally the retailer who brews the coffee and sells it to the final consumer. This is where River Side Cafe stands (Kansal & Kapoor, 2003). However, in this case, the producer of the products on sale, i.e. coffee and tea, is the cafe and the customers of the products are the clients who throng into the company premises to taste a cup of pure traditional coffee and tea imported from Mexico. As such, River Side Cafe only considers itself and its customers in setting up its channels of distribution. The main product sold by the cafe is a service. Services are inseparable from their producers. Therefore, it is unlikely for the cafe to seek out external distributors of their coffee and tea rather than themselves. In addition, quality service delivery comes along with customer experience journeys and experiences that should enable the organization deliver maximum satisfaction to their consumers.

This is narrated skillfully in the first three chapters of the book which are on her early years. Lazo then goes on to describe how her injuries and difficulties as a child shaped her adult life in the era of the civil rights movements and other discourses which gave her the impetus to write and publish her books. This work provides a very authoritative discussion about how Alice Walker was shaped and how she evolved to become who she is now. This will be an important element in the research because it will provide a reference point for the assessment of Alice Walkers personality. The book also discusses some of the social activities that Alice Walker is connected with at the moment. Professor Bloom is a world acclaimed lecturer at Yale. He is a top professor in the Humanities. He has won a lot of prizes for his ability to critique literary works and provide the literary elements of such projects. Her book on Alice Walker provides a complete guide to Alice Walkers literary style. Bloom gives a critical analysis of her major works and identifies the main elements of literature in each of the books. This is done through a series of critical essays that provide in-depth evaluations of each and every important tool that Alice Walker used to convey her plot and characters. This is vital for the research because it provides a convenient point through which references can be made about the literary elements of Alice Walkers works. Also, since it is a compilation of various critiques, it provides a summary of the plot of Alice Walkers major projects. This will give an insight into projects that cannot be read in-depth for some critical

A Case Study About Healthcare Leadership

A Case Study About Healthcare Leadership Effective leadership is essential in health care organisations as in other organisations. It is necessary for driving innovation, effective patient care, patient safety, improving working within clinical teams, sorting out issues within emergency context and other aspects necessary for effective and efficient running of healthcare organisations. Transformational leadership has often been prescribed as the gold standard of healthcare leadership(Gopee and Galloway 2009).This essay sets out to: briefly discuss the concept of leadership; highlight why leadership is important in healthcare; make a distinction between the closely-related concepts of leadership and management; briefly highlight how power relates to leadership; describe some leadership approaches applicable within the context of healthcare organisations; describe leadership styles visible in healthcare; present a case study set in a teaching hospital practice setting in Africa ; critically assess the leadership approaches operating within the setting and its effect on organisational performance ;and make recommendations on improving leadership practice within the specified setting. What is leadership? Leadership can be defined as the ability of an individual to influence a group of people to achieve a goal(Bryman 1992).It is also noted that leadership can have four possible meanings, namely: the activity of leading; the body of people who lead a group; the status of the leader; and the ability to lead'(Gopee and Galloway 2009). Kouzes and Posner (2007) suggest some characteristics of an effective leader namely to: be more effective in meeting job-related demands; be more successful in representing their units in upper management; create higher performing teams; foster renewed loyalty and commitment; increase motivational levels and willingness to work hard; and possess high degree of personal integrity. Why leadership in healthcare? Effective leadership and management has been found to contribute to efficiency of health care services, performance (McColl-Kennedy and Anderson 2002) and satisfaction of staff employed within them.(Bradley and Alimo-Metcalfe 2008) researched the causal relationship between leadership behaviours and the performance and productivity of staff and found that engaging leadership improved employee engagement and performance. (Morrison, Jones et al. 1997) studied the relationship between leadership style, empowerment, and job satisfaction on nursing staff at a regional medical centre. They used Basss Multifactor Leadership Questionnaire to measure leadership style, items from Spreitzers Psychological Empowerment instrument to measure empowerment, and the Warr, Cook, and Walls job satisfaction questionnaire to measure job satisfaction. The authors found that both transformational and transactional leadership were positively associated with job satisfaction. Some other researchers reported that good leadership skills impacted on patient safety and quality of care (Corrigan, Lickey et al. 2000; Firth-Cozens and Mowbray 2001; Mohr, Abelson et al. 2002).Furthermore, leadership skills are essential in the world of public health policy and leadership is one of the core competencies required of public health trainees(Faculty of Public Health 2010). Leadership versus management Relevant to this discourse is making a distinction between leadership and management. They are two similar but distinct concepts. Management is seen as seeking order and maintaining stability while leadership is seen as seeking adaptive and constructive change. Leadership in the healthcare context aims to influence practitioners towards the achievement of the common goal of quality patient care. On the other hand, management as a process coordinates and directs the activities of an organisation to ensure it achieves its set objectives. Management ensures healthcare resources (human such as doctors, nurses and clerical staff and non-human resources like medical devices and consumables) are utilised in an efficient way whilst delivering effective healthcare service(Gopee and Galloway 2009). However, leadership is known to be complementary to management (Kotter 1999; Zaleznik 2004). Leadership theories and styles in healthcare A number of theoretical leadership approaches can be applied within healthcare .However, not all aspects fit in perfectly into healthcare, and thus some adaptation may be required. Transformational leadership Transformational leadership is a widely advocated approach for healthcare. Transformational leadership is one of the contemporary leadership approaches that are concerned with how an individual influences others in a group in other to achieve a common goal .Transformational leaders seek to accomplish greater pursuits within an organisation by inspiring other members of the group to share their vision for the organisation. Transformational leaders motivate and raise the morality of their followers and help them reach their fullest potential. Mohandas Gandhi Nelson Mandela have been cited as transformational leaders(Northouse 2007). In an organisational context, a transformational leader is one who attempts to change the organisations values in order to portray a standard of fairness and justice while in the process emerging with a better set of moral values. Transformational leadership is about the collective good of an organisation; it is expected to bring about organisational change .It aims to inspire commitment to the organisations vision and ideals .In healthcare, teams of health care professionals are inspired to achieve the highest quality of patient care irrespective of limiting situations (Gopee and Galloway 2009). The concept of transformational approach of leadership was popularised by the political sociologist, leadership expert, and presidential biographer- James Macgregor Burns in his seminal work Leadership written in 1978. In this book, he described the leadership styles of some political leaders. Bernard Bass widely cited in leadership literature built on the work of Burns and argued that leadership is an influence process which motivates followers to perform above their expected output by raising the followers level of consciousness about the importance and values of the shared goals, operating beyond their self-interests and addressing higher level needs'(Bass 1985). He also suggested that transformational and transactional leadership models where a continuum rather than mutually exclusive entities. Four qualities or behavioural have been widely cited as the leadership factors which are an integral part of transformational leadership- the 4 IS(Bass 1985; Avolio, Waldman et al. 1991) namely: idealised influence-describes the ability of the leader to act as role model s whose followers emulate. This factor is sometimes mentioned as being the same as charisma; inspirational motivation-the ability to inspire the members of the group to become integrated with the vision of the organisation while transcending their own self-interest ; intellectual stimulation-the stimulation of creativity and innovation in the followers so that they are able to discover and develop new ways of sorting out issues within the organisation as they arise; and individualised consideration-portrays the need for leaders to recognise the strength and weakness of each member of the group foster on the development of followers and help each in the achievement of goals through personal development. Transactional leadership, on the other hand, is one based on reward for performance. A transactional leader is described by (Bass 1985)as one who prefers a leader-member exchange relationship, in which the leader meets the needs of the followers in exchange for meeting basic expectations. In essence, a transactional leader has a penchant for avoiding risks and is able to build confidence in subordinates to allow them to achieve goals. The transactional leadership construct has three components: Contingent reward -clarifies what is expected from followers and what they will receive if they meet expectations. Active management by exception- focuses on monitoring tasks and arising problems and correcting these to maintain current performance. Passive -Avoidant Leadership-reacts only after problems become serious and often avoids decision-making(Avolio, Bass et al. 1999). Connective leadership is a theory based on the premise that establishing alliance with other organisations via networking is essential to the success of an organisation. Collaboration between different clinical teams within a hospital and with other health care organisations and service industry exemplifies this.(Klakovich 1994) suggests that empowering staff at all levels facilitates the collaboration and synergism needed in the reformed health care environment of the future. Distributed leadership Clinical leadership Leading change in the University College Hospital Ibadan: a failed effort in transformation? Healthcare in Nigeria is faced with enormous challenges. The University College Hospital Ibadan was established in 1948 is the foremost tertiary hospital in Nigeria. It is basically organised as a public sector organisation whose primary goal is to provide the best available healthcare service in the western region and the country as a whole. Funding is from the Federal Government and its activities are regulated by the Federal Ministry of Health which is also responsible for the implementing healthcare policies. However, a private section of the hospital was established recently modelling the prevalence of internal markets currently prevailing within healthcare. Currently, the University College Hospital produces 1 in every 5 physician in the nation. It was initially commissioned with 500 bed spaces but has now grown to a 850 bed hospital. The current average bed occupancy ranges from 60-70%. The hospital board of management comprises: the Chairman the Chief Medical Director; the Chairman, Medical Advisory Committee; the Secretary of the Board; representatives of public interest; representative of the Nigerian Medical Association; representative of the State Government; representative of the University of Ibadan Senate; representative of the Vice Chancellor of the University of Ibadan; and the Provost of the College of Medicine. The organisation has three principal officers but the day -to -day running of the hospital falls on the Chief Medical Director who demonstrates some attributes of transformational leadership in order to bring about change . Vision To be the flagship tertiary health care institution in the  West Africa  sub-region, offering world-class training, research and services, and the first choice for seeking specialist health care in a conducive atmosphere, renowned for a culture of continuing and compassionate care'(University College Hospital Ibadan 2009). Mission Statement Rendering excellent, prompt, affordable, and accessible health care in an environment that promotes hope and dignity, irrespective of status, and developing high quality health personnel in an atmosphere that stimulates excellent and relevant research. (University College Hospital Ibadan 2009). The Chief Medical Director is an assigned leader-one whose leadership is based on formal position and legitimate authority .His appointment by the Federal Government in 2003 was proposed to be vital contribute to the improvement of the hospital. A trained obstetrician, he participates actively in the care of pregnant women. With increasing satisfaction of healthcare staff, patient satisfaction rates began increase. A new magnetic resonance imaging ,centre, cancer treatment and research centre.new innovationsthe bank to collect..Satellite pharmacies were established in order to reduce the time and effort spent by staff in getting patient medications. staff development through exchange programmes, establishment of day care centres.shows his entrepreneurial qualities. Despite it all, mortality rates remain high, medical errors are frequent, post operative patients developed infections frequently and physicians were verbally and physically abused by patient relatives. Private patients get more attention from the junior doctors and other specialist consultants. It has now been found wanting in serving the needs of the local population. Repeated nurses strike ,junior workers strike .. SWOT analysis of the University College Hospital Ibadan Strengths Weaknesses Fairly well-equipped operating theatres Large newly renovated and well-built hospital blocks Excellent medical microbiology services, including HIV testing Residential accommodation for house officers and other specialist trainees Strong alliance with international organisations for infectious diseases research Expensive laboratory services Relative shortage of medical staff Politicisation of board of management appointments Weak administrative set-up Expensive pharmacy services Inadequate funding Delay in staff remuneration Few opportunities for exchange programmes for students and residents Inadequate supply of electricity Opportunities Threats Federal Governments commitment to the development of tertiary care More research funding Competition from existing private and missionary hospitals Incessant industrial actions embarked upon by nursing staff, physicians and support staff Critical analysis of the leadership approach in Despite recognition that transformational leadership has some positive benefits, it is particularly difficult to act out within public services organizations Frederickson 1996 cited in (Currie 2005).Though with its own merits, the view that transformational leadership is the solution for healthcare leadership has been criticised. While there are advantages of using the transformational approach, it is not a universal panacea. Transformational leadership alone cannot account for effective outcomes in this health care organisation. Other aspects like of organisational behaviour such as management practices, knowledge management, and organisational culture are also key determinants. A US study of 370 hospitals explored the relationship between leadership, quality and knowledge management and found that transformational leadership is fully mediated by knowledge responsiveness in its effect on organisational performance (Gowen, Henagan et al. 2009). Effective knowledge management is thus strong confounder in the relationship between leadership and organisational performance. In relation to organisational culture, there is also a link between hospital and ward culture with patient outcomes. Research has shown that hospitals with a strong hand-washing policy and practice recorded fewer infections. Transformational leadership, while focusing on change, may not be in consonance with performance management needed for accountability in healthcare(Firth-Cozens and Mowbray 2001). The context in which a leadership style operates is also a key determinant on outcome irrespective of leadership style. Studies have shown the relationship physician working hours, stress, and burnout on quality of care and patient outcomes (Firth-Cozens and Cording 2004; Landrigan, Rothschild et al. 2004).Tackling job stress is thus a key avenue for improving quality of care. The Chief Medical Director needs to understand the complexity within which healthcare is delivered and translate it to his practice setting rather than trying to adopt a prescribed process. Conclusion This essay has highlighted a number of leadership theories, skills, style leadership in healthcare has been assessed. There is no perfect style or approach to leadership and healthcare organisations pose a complex setting. Several approaches may operate simultaneously. Context, political environment and social factors will affect leadership styles and approach. Clarifying the situation of a practise and flexibility is very important. Numerous challenges face healthcare organisations in Nigeria. The ability to deliver safe, effective, high quality care within organisations with the right cultures, the best systems, and the most highly skilled and motivated work forces will be the key to meeting this challenge. Conflicts still exist as to what constitutes good practice in leadership and there is no perfect set of prescriptions for effective leadership. All the existing theories merely provide a framework for which practise can be based. Healthcare organisations are a complex setting and to achieve efficiency and effectiveness, healthcare leaders need to be very flexible in their leadership .The University College Hospital should adopt an blend of different theories and styles in practice. Recommendations Leadership can be taught (Parks 2005)and improved through organising leadership development programme. It is also noted that leadership development programmes improved efficiency and quality in healthcare(McAlearney 2008). Top management and clinical staff can take these.(Kotter 1990) suggests that organisations can nurture and grow their own leaders while adapting to constant changes(Parks 2005) There appears a need for leadership approaches that are sensitive to a context in which there are significant professional and moral concerns graeme.

Analysis of an American Trial: The Salem Witch Trials :: American America History

Analysis of an American Trial: The Salem Witch Trials The Salem Witch Trials all began on January 20, 1692, with nine-year-old Elizabeth "Betty" Parris and eleven-year-old Abigail Williams, daughter and niece of the village reverend Samuel Parris, beginning to exhibit strange behavior, such as blasphemous screaming, convulsive seizures, trance-like states and mysterious spells. Within a short period of time, several other Salem girls began to illustrate similar behavior; physicians resolved that the girls were under the control of Satan. Reverend Parris conducted prayer services and public fasting in hopes of relieving the evil forces that tormented them. In an effort to expose the "enchantress", one man baked a "witch cake" made with rye bran and the urine of the ill girls. This counter-magic was meant to reveal the identities of the "witched" to the ailing girls. Pressured to identify the cause of their misfortune, the girls named three women, including Tituba, Samuel Parris' slave, as witches. On February 29, warrants were dispatched for the arrests of Tituba, Sarah Good, and Sarah Osborne. Although Osborne and Good sustained guiltlessness, Tituba confessed to seeing Lucifer, who appeared to her "sometimes like a hog and sometimes like a great dog." What's more, Tituba certified that there was a collaboration of witches at work in Salem. On March 1, Magistrates John Hathorne and Jonathon Corwin investigated the three women in the courthouse in Salem Village. Tituba confessed to pursuing black magic. Over the next few weeks, other villagers came forward and testified that they too had been traumatized by or had seen strange phantoms of some of the village members. As the witch-hunting prolonged, charges were made toward many different people. Frequently unmasked were women whose behavior was somehow disturbing to the social order and formalities of the time. Some of the accused had records of unlawful pastimes, including witchery, but others were faithful churchgoers and people of high status in the society. From Mid-March to early April, Martha Corey, Rebecca Nurse, Elizabeth Proctor, and Sarah Cloyce were accused of witchcraft. Soon after Corey, Nurse, and Proctor were examined before Magistrates Hathorne, Corwin, Deputy Governor Thomas Danforth, and Captain Samuel Sewall. During this analysis, John Proctor was also jailed. Then Abigail Hobbs, Bridget Bishop, Giles Corey and Mary Warren were taken into account. The only one to confess was Hobbs. On April 22, Nehemiah Abbot, William and Deliverance Hobbs, Edward and Sara Bishop, Mary Easty, Mary Black, Sarah Wildes, and Mary English were examined before Hathorne and Corwin.

After the dethronement of Louis XVI, politics for the first time in France had become an issue for the French to systemize and regulate. No longer did the citizens have to follow the will of the kings’ â€Å"godly design† but now would be represented by a republic of the people. Very quickly political factions began to emerge across France. The two major political factions of the Convention were the Jacobins and the Girondins, which held very opposite beliefs of the future of the monarchy. However, both had a strong ambition to gain supremacy in the Convention and to ultimately control the direction of the Revolution. Although in doing so the factions had to gain the support of the Marais, the group that did not belong to any faction. The first issue for the elected deputies of France was to determine the fate of the former King of France, Louis XVI. The strong will of the Jacobin’s beliefs and the ineffective representation of Girondin philosophy strengthened J acobin support and ultimately determined the death of Louis XVI.   Ã‚  Ã‚  Ã‚  Ã‚  All three political groups were not the same as the ones found in today’s political campaigns. These historic parties had, â€Å"no party machinery, no party funds, no party discipline on voting and in most cases no party platform. They were at best loosely-connected groups of men who had been friends, who shared political ideas, or who were thrown together on specific issues.† However the citizens believed them to be their representatives in the new regime that would debate for the good of the country based on the new principles. The Jacobin faction was formerly the Society of the Friends of the Constitution and was made up of intelligent bourgeoisie. After the Assembly moved to Paris the group enlarged and rented the former residence of the Dominican monks which were known as the Jacobins, a name eventually inherited by the society. The Jacobins strongly supported power in Paris, and heavily pushed egalitarian aspirations. The Jacobins firmly belie ved that their group represented the people. During the course of the trial of Louis XVI the approximately one hundred and ten members of the Mountain (as they were referred to in the convention because of their choice of the higher seating) believed that Louis should be â€Å"judged by the highest tribunal in the land, the people in the revolution on August the 10,1792.† Their final conclusion was that Louis was guilty of treason and that he should be punished by way of the guillotine.

Molecular Archaeology

Different methods have been used and are being used in the analysis of archaeological data. Among others, different archaeometric fields such as paleoecology (paleozoology, paleobotany and pllenanalysis), dating methods (radiocarbon-dating and dendrochronology) and analytical chemistry had been used for the evaluation of the quantity and quality of different archaeological substances (Kiesslich, n.d.). Given the nature of archaeology, evaluated data are analyzed on the point of view of history. The recent discoveries in science particularly in genetics and molecular biology have given rise to another method of scientific analysis of archaeological data. The new developments allow easier investigation of ancient remains not only through paleoecology, dating and chemical methods but on a molecular level. This new branch of archaeological analysis is what is now known as Molecular Archaeology. Christianson (2007) of the Minnesota State University gives a more perspicuous description of the field. According to him, Molecular Archaeology is an â€Å"†¦emergent field in archaeology that has been brought about by the advancements of the recognition and understanding of DNA, focusing on the acquisition of either DNA or mtDNA (mitochondrial DNA) and being able to determine species of natural archaeological finds as well as determine blood lines and/or sex of animal or human remains.† It is this use of the DNA in the analysis of archaeological data that differentiates Molecular Archaeology from the other methods of archaeological analysis. It is the biological function of this DNA that makes molecular archaeology an irreplaceable field in analytical archaeology. This DNA contains genetic information which, once known, could provide special information about the individual properties of the probe (Christianson, 2007). These individual properties include one's species, population, and gender. Also, Through the use of DNA residues, accuracy in reconstructing subsistence and related cultural activities is more probably. As a result, we gain more knowledge and understanding of the lives of our ancestors and the environment they lived in as well as of the other creatures that coexisted with them (Christianson, 2007). There was a time when molecular archaeology seemed to be inconceivable. This was when scientists believed that DNA-preservation was impossible in biological remains. Previous studies have shown that it only took days or even hours for degradation to occur after the death of an individual. With degradation, of course, is the loss of significant genetic information (Keisslich, n.d.). It is one study in the early eighties defied this scientists' limiting belief on the relationship between degradation and DNA-preservation and paved the way for molecular archaeology and the use of DNA in the analysis of archaeological data. â€Å"This is the successful detection of intact genetic information in a 4000-year-old Egyptian mummy† (Kiesslich, n.d.) Furthermore, the invention of analytical methods in molecular biology boosted the field of molecular archaeology. â€Å"In 1988, Mullis and Saiki published a study on Primer-directed enzymatic amplification of DNA with a thermostable DNA polymerase†. Practically, they invented the PCR or the Polymerase Chain Reaction technique which made possible the detection and characterization of even minimal traces of DNA. In theory, the presence of even a single intact molecule of DNA can give a positive result (Kiesslich, n.d.) †The impact of molecular archaeology particularly its use of DNA in evaluating data has been proven to be a great leap in archaeological research†. Because DNA is a huge aspect of molecular archaeology, it is necessary even for the general studies of this subject to include information on the nature of the DNA. DNA is a helically-twisted macromolecule consisting of a sugar-phosphate backbone. â€Å"Each sugar in the DNA's sugar-phosphate backbone is bound to one side-chain which may be different for each unit†. It is this side-chain that represents a single basic unit of DNA or DNA-base. It is the connection between a few to several billions of base-pairs connected by one polymer unit that produces a double helix, particular to the DNA. (Kiesslich, n.d.) The function of the DNA is mainly the maintenance and passing of genetic information from parent to progeny. This genetic information is encoded in 4 different letters (A, C, G, T) which represent the bases or the basic units. Three of the letters together correspond to the next superior information unit (Kiesslich, n.d.) The DNA not only functions for the maintenance and passing of genetic information but also for the control of the biological functions of each cell. For living organisms, it is located in the nucleus of the cells and in small cellular compartments called mitochondria. This mitochondria are considered as the powerhouses of the cell because it provide for the energy needed for cellular processes. Like nuclear DNA, mitochondrial DNA has their own chromosomes. â€Å"In general, a cell contains only two copies of nuclear DNA and as much as a thousand copies of mitochondrial DNA â€Å"(Kiesslich, n.d.). What is crucial to the nature of the DNA is the sequence of its 4 discriminable bases or the base-sequence. It is this base-sequence that represents the genetic information passed on from parent to progeny and controls the cellular chemical reactions. It is this sequence that is the targeted information in the analysis of archaeological facts and this sequence can only be determined through the application of methods in molecular biology (Kiesslich, n.d.). Information given by an individual's DNA is not limited to the individual but also to pathogens which include microorganisms and bacteria, as well as biological materials and the diet of a settlement (Kiesslich, n.d.). DNA of microorganisms and bacteria can be determined through paleopathology and paleoepidemiology. DNA of biological material can be determined through paleoecology, paleobotany and paleozoology. An extracted intact DNA would give the whole genetic information of an individual. This genetic information can be accessed using different sequence-specific DNA probes which also provide information required for archaeological analysis (Kiesslich, n.d.) There is a difference between the extraction of DNA from the nucleus and DNA from the mitochondria. Note that DNA from the nucleus persists only as two copies for every cell while mitochondrial DNA persists at an average of a few thousand copies per cell. â€Å"Nuclear DNA and mitochondrial DNA require a minimum state of preservation to obtain the specific sequence information†. The greater quantity of mitochondrial DNA allows it to be more readily accessible compared to nuclear DNA. It is also more resistant to degradation processes after death as well as diaganetic influences compared to nuclear DNA (Kiesslich, n.d.). The two types of DNA are different in the types of information that can be obtained. In nuclear DNA, information about an individual's genetic constitution can be obtained. This includes the individual's species, gender, fingerprint and kinship with other individuals. Meanwhile, the mitochondrial DNA provides information that allows the assessment of maternal lineage within a community. This is because mitochondrial DNA is exclusively maternally hereditary. The mitorchondrial DNA's comparatively slow mutational rate also allows greater evaluation of genetic context for individuals. In effect, individuals can be classified through middle and long-range temporal classification (Kiesslich, n.d.). Using information on the X and Y chromosomes, gender can be determined easily using molecular biological methods (Faerman and Filon, 2005). As it is known, gender is one of the most significant features of an individual and is likewise significant in archaeological analysis. Among other parts, gender can be and is usually determined using the teeth and the bones (Kiesslich, n.d.). Sex-specific genes are located in the X and Y chromosomes. Still, the determination of gender is not limited to molecular biological means. The determination of the gender of an individual remains can be done through conventional methods including morphometry. This happens when convenience is not the issue but the quality of the sample itself when it is too damaged or when the remains that are analyzed belonged to an infant. As a rule, a few grams of bone or tooth is enough for DNA-analysis (Kiesslich, n.d.). †Gender determination through DNA-analysis can be exemplified by the study done in South Israel, at a bath house at a burial site of Roman Askalon†. It must be noted that in Ancient Askalon infanticide was a widespread phenomenon (The Advent of Molecular Archaeology, 2005). †Behind the bath house, archaeologists found more than 100 skeletal remains of infants which at first were thought as the remains of unwanted girls†. The epigraph stating â€Å"Enter, Enjoy and†¦Ã¢â‚¬  and the several lamps with erotic motifs gave rise to a theory which was confirmed using DNA-analysis. Through gender determination by DNA-analysis, it was found out that the skeletal remains that were found did not only belong to unwanted girls but also to unwanted boys. The bath house was confirmed to be a brothel and the skeletal remains were the infants of the women who used to work at the place (Kiesslich, n.d.). Meanwhile, the issue on whether or not tuberculosis was brought to Peru by Columbus and his successors was clarified using DNA analysis. â€Å"One study reported that the DNA of tuberculosis pathogens already existed even among 600-900-year-old Peruvian mummies† (Kiesslich, n.d.). Nuclear DNA-analysis is also used in the identification of remains. In history, the remains of Josef Mengele in Brazil as well as the identification of the remains of the Romanov family in Jekatrinenburg after the Bolshevik Revolution were identified using DNA-fingerprinting (Kiesslich, n.d.). The analysis of organic residues in some jars found in Egyptian Amphorae allowed the discovery of what commodities were transported to Egypt during the Late Bronze Age and the links between the sources of the jars, the commodities and the way of transport of substances in the Mediterranean world (Stern, 2001). Mitochondrial DNA analysis was used in the investigation of the Tyrolean Ice-man (The Advent of Molecular Archaeology, 2005). The findings of the investigation revealed a high DNA-sequence homology to today's population in the Northern alps (Kiesslich, n.d.) and showed a great fit to the Northern European context. In this case, clothes and tools associated with the findings were also investigated aside from the individual body, giving an idea on vegetation during the era (Kiesslich, n.d.). DNA-analysis also covers topics historical and anthropological topics particularly population-genetics. Population-genetics include the tracing of migrations and distributions of populations. For example, kinship analysis was done with some individuals in Forida (Kiesslich, n.d.). DNA-analysis can also be used to trace genealogical origins and also in the determination of possible threats of diseases from ancestors. Source materials for DNA-analysis are not limited to bones and teeth. As a matter of fact, anything that could possibly contain DNA, even if not part of the individual's body can be a source material. â€Å"Source materials can range from biological remains such as skeletons, bodies, bones, hair, teeth, forensic and medical preparations, museum specimens, fossils and objects that an individual has come in contact with† (Kiesslich, n.d.). It must be remembered that DNA-analysis is a procedure which involves the destruction of the specimen. This implies that once a specimen has been used for analysis, it cannot be reused. On the other hand, even small amounts of materials, say, a piece of hair or a gram of bone is enough for any DNA-analysis as long as the specimen is of quality, depending on the source's chemical, physical, geological, ecological and biological history (Kiesslich, n.d.). †A DNA can be expected to be intact and well-preserved if it has been maintained at low-temperatures such as the case of the Tyrolean Ice-man, or if it has been maintained in arid places†. As a rule, DNA-degradation happens under humid conditions so specimens coming from deserts, and in polar regions or any other setting with similar conditions would produce more intact DNA specimens and more successful DNA analysis. Other conserving factors include anaerobic conditions such as that in Florida during the kinship analysis and the quantity of possible DNA specimens such in mummies (Kiesslich, n.d.). The less a specimen is affected by diagenetic processes, the more intact and well-preserved it will be when used for DNA-analysis. This is the reason why teeth and bones are commonly used for DNA-analysis. Their structure, and rigidity as well as the little hollow spaces with single cells, which undergo individual post-mortem mummification (Kiesslich, n.d.). In addition, these specimens are less affected by natural contamination during the life of the individual as well as post-mortem contaminations. Contemporary contaminations in the specimens can also be easily removed before extracting the DNA. As noted earlier, teeth and bones are suitable material sources for the determination of gender and for any other DNA-analysis (Kiesslich, n.d.). In molecular archaeology as well as in any other field that require genetic analysis, collection of samples and pre-treatment require maximum precautions. This is to prevent contemporary errors which are possible sources of errors. Errors are especially crucial in DNA-analysis since specimens are not infinite (Kiesslich, n.d.). One simple precaution is to wear gloves and safety-masks. Also, tools and containers that will be used in the analysis should be sterile and free from other DNA contaminants. It must also be remembered that probing of specimens should be done directly at the excavation site, sealed and only opened until it get to the laboratory. All these should be obligatory to prevent contamination and thus, errors (Kiesslich, n.d.) There are many procedures for the extraction of DNA from material sources. Naturally, speciments are cleaned first to remove physical contaminants such as soil and dirt. Specimens are then homogenized and placed in an extraction buffer. This extraction buffer contains compounds that are necessary for the breaking of the source-matrix. The breaking of the source matrix is done by decalcification or and proteinase-digestion. The end product is the extracted solubilized DNA (Kiesslich, n.d.). Similar to extraction, isolation and purification are also done through different procedures. Before doing the process, the chemical and physical conditions of the source material must first be evaluated. This is another preventive procedure to minimize errors from contaminants. Once the DNA in the source material has been purified and contained in an aqueous solution, substances that are co-extracted with the DNA including humic acids and other chemicals which have similar properties with the DNA must be removed to avoid false negatives in PCR reactions. These co-extrants could also inhibit enzymatic reactions (Kiesslich, n.d.). The most powerful tool for the investigation of DNA is the Polymerase Chain Reaction (PCR) because of its sensitivity which allows even a single intact DNA enough for detection. The PCR is an amplification procedure that is sequence specific. â€Å"Here, sequence specific DNA probes are added to reactions considering reaction parameters necessary for the process†. Through this, the target sequence is amplified until detectable amounts are obtained. However, further care must be done in order to avoid contamination, particularly contemporary ones. Contemporary contaminants are better preserved in the PCR. To manage this, blank extracts and zero-controls must be done for every extraction. In sum, controls are necessary to for the verification of the authenticity of the results and in order to trace possible contaminations that are present (Kiesslich, n.d.). Zero-controls are PCR-reactions which do not contain the DNA being analyzed (Kiesslich, n.d.). They are blank extracts which contain everything that is required for the reaction used in the DNA-analysis such as solutions and buffers. In the same way as the source material, these controls undergo the same extraction steps. Much has been transformed by the discovery of DNA. In the past, archaeological investigations may be limited to the physical level. Today, it has reached the era when Archaeology intersects with Molecular Biology. There are still lots of evidences to discover. history is still filled with gaps. With the advent of Molecular Archaeology, strands may just be made and gaps may just be filled.

Differences Between the Wartime, Presidential, and Congressional Reconstruction Essay

There are similarities and differences between the Wartime, Presidential, and Congressional Reconstruction. Each had a purpose and plan. There was a major difference between the Republican President and Republican Congress that caused many conflicts. The Wartime Reconstruction actually started during the war. Lincoln in the beginning wanted settlement of blacks in countries or something known as repatriation. A major part of this Wartime Reconstruction was the Proclamation of Amnesty. What this did was offer a Presidential pardon to all Southern whites who took an oath of allegiance to the Union and accepted abolition of slavery. The only people that were excluded from this were Confederate official and high-ranking military officers. In states where ten percent of male population took the oath they would be able to reestablish a state government. This policy was carried out in Louisiana, Arkansas, and Tennessee. This Wartime Reconstruction also included Lincoln’s Emancipation Proclamation. This freed slaves in the states that were at war with the Union. Both President Lincoln and President Johnson wished to give back land to pardoned ex-Confederates. President Lincoln and Congress were similar in wanting to refute pardons to those who ill-treated or murdered captured black and white Union soldiers. They did agree on this matter. While President Lincoln only required ten percent of allegiance from past Confederates, Congress wanted the majority of white men in Confederate states to take the oath of allegiance. Lincoln was assassinated and Andrew Johnson took presidency. He favored harsh punishment for traitors. He issued two proclamations without help of Republicans. This was the Presidential Reconstruction. When he issued the two proclamations it caused a division. It covered official pardon for whites except Confederate officials and military officers worth more than twenty thousand dollars, and he names a provisional government for North Carolina. Only whites with amnesty could vote there. The South was disobedient and none of the state conventions enfranchised a single black. Johnson issued thirteen though sand five hundred Presidential pardons to those he earlier hoped to keep out. There were many ex-Confederates who were elected to Congress. Also the state legislatures in the south demoted blacks to a second class status, and this was known as the Black Codes. These codes states blacks were not allowed to vote, be on juries, testify against whites, could not interracially marry, and it was most unfair in Mississippi and South Carolina. Johnson like Lincoln wanted to restore the Union in as little time as possible. Congress comes in to play in December 1865. The Congress was made up mostly of Republicans and they refused to let past Confederates to take their seats in Congress at this time. This marked the beginning of Radical Reconstruction or sometimes known as Congressional Reconstruction. The president and the congress did not agree on many issues. Congress overrode President Johnson on the Civil Rights Act of 1866, The Fourteenth Amendment, and the Freedmen’s Bureau Bill. The Fourteenth Amendment spelled out rights of both black and white citizens as equal. It prolonged Federal powers for the enforcement of civil rights. States that approved the Fourteenth Amendment were considered reconstructed, and Tennessee did so. President Johnson advised other southern states to oppose doing this. Congress passed many laws to limit President Johnson’s powers. They passed the Reconstruction Acts of 1867 which set new procedures for readmission to the Union. Johnson did not agree with this act and resisted it. When President Johnson removed Edwin M. Stanton from the head of the War Departments Republicans were very upset. They charged Johnson with the Tenure of Office Act and Johnson was impeached. After President Johnson’s impeachment, the Fifteenth Amendmen t, which prohibited states from denying vote based on color, was ratified. This Radical Reconstruction was successful in passing the Thirteenth, Fourteenth, and Fifteen Amendments. Congress also wanted married law affirmed in the South for the period of Reconstruction and they wanted to discipline ex-Confederates. President Lincoln and Congress did not agree with how many pardons President Johnson gave out. The Wartime Reconstruction, Radical or Congressional Reconstruction, and the Presidential Reconstruction all had their similarities and differences. Each was designed by someone different and had a specific plan and goal in mind. The differences between the president and congress caused many splits and problems. The Radical Reconstruction was most successful in my opinion.

Internet social networking's effects on teenager's social lives Essay

Internet social networking's effects on teenager's social lives - Essay Example Such sites allow the members to socialize with their friends by adding them to their profile, sending them messages and commenting on their statuses displayed on the pages of their profiles. Social networking sites most commonly in use today are Facebook and Twitter. Most teenagers necessarily visit these websites several times in a day all over the world. According to a recent research generated by the Pew Internet Project, as many as 93 per cent of the teenagers in America between the age of 12 years and 17 years are regular users of the internet, and 55 per cent of such teenagers spends most of the time using social networking websites (Hall). Social networking sites cause a lot of troubles in the life of teenagers. As a result of the expanded social circle because of internet social networking, teenagers are prone to fall in the hands of pedophiles and kidnappers. Internet social networking increases the interaction of a teenager with others. In fact, many studies have found the social networks of internet using teenagers to be much larger than others that do not use the internet. Not only their social circle increases, but also the way they communicate changes. Nowadays, many teenagers can be heard speaking to one another in slang. The time that teenagers spend socializing with others in the virtual world is no less effective than the real world for building relationships and socializing with others. ... The predators can easily project themselves as teenagers. This allows them to draw the teenagers into harmful activities in the real world along with the virtual world. They send messages to the teenagers via these websites. Many teenagers respond to them. The predators may use social networking sites to drive the teenagers into the business of drug dealing or child pornography. Drug smuggling, prostitution, and cyber terrorism are the common results of crimes conducted through net. The privacy control is also an important feature of most of the social networking sites, but not many teenagers are prudent enough in their use of the internet to use the privacy control. Besides, not many predators get caught by the monitoring of profiles. Identity theft is one of the biggest risks of social networking through websites, that exposes teenagers to the risk of abduction. Teenagers tend to display their personal pictures on their profiles and display their contact numbers, house numbers, and other necessary information that is required by the kidnappers. There are many causes of such a massive display of personal information on the websites. First, children tend to display their complete and accurate information so that it would be easier for their old and lost friends to access them online. Secondly, many teenagers tend to display information to show off that they are living in a particular city or studying at a popular college or school or have joined some famous club in the town. There are many other causes as well. Social networking sites are an excellent source of information regarding any individual as well as his/her family for the kidnappers. In the recent years, a lot of people have been kidnapped all over the world. Teenager boys may be

UK Tax System Assignment Example | Topics and Well Written Essays - 3250 words

UK Tax System - Assignment Example Profit margins are small: Higher expenditure and lower selling prices will lead to a lesser bottom-line and so lower dividend payments. This problem can be overcome by working efficiently and effectively to generate high sales and stand up competitively by not lowering the prices of goods. Late payments from customers will seriously influence the cash flow: In this case, credit terms should be discussed beforehand with customers and be kept strict so as to make inflows earliest. Key supplier (s) will gradually be dissatisfied: If payment problems to suppliers arise due to the expansion or new orders being taken, suppliers will be alarmed and dissatisfied with the company. To cure this problem, the company should beforehand discuss the situation with the suppliers and the credit terms should be precisely conveyed so as to prevent future problems. (b) There are a number of short-term finances available to the company to finance its proposed expansion; two of them are discussed as follo ws: Bank Loan, and Bank Overdraft Bank Loan: In the case of this company, bank loan pertains to the short-term period usually equal to or less than a year. The bank according to the credit rating lends the company a certain amount of loan needed and on an interest rate negotiated. Strengths: Amount will be received on one-time basis and the payment will be done in monthly, quarterly or semi annually installments Cost of borrowing is lower than other means such as Bank Overdraft Interest rates are low Reliability and security is always there in terms of getting the money from the bank on time and for a certain period of time contracted upon with the bank Weaknesses: The loan will be secured against the company’s assets The riskier the business is, the higher the interest rate the bank will charge to cover up its risk Arrangement fees, as well as repayment fees, will have to be paid In case of early repayment of loan, an extra charge will have to be paid Bank Overdraft: It is a kind of loan arrangement under which a bank extends credit allotted to a company up to a maximum amount called the overdraft limit against which a customer or company who has current or checking account with the bank can write checks or make withdrawals (Business Dictionary 2011). Strengths: Appropriate for short-term financing Not secured against any asset of the company so the process of obtaining the loan Is expedited Only charged for the amount overdrawn from the bank account and also pertaining only to the period of time the overdraft facility had been used by the company Weaknesses: The bank overdraft amount has to be paid on demand of the bank. This puts the company at a great risk in the case when the bank decides to request the money back at an inconvenient time for the business High-interest rate is charged (c) Capital Gearing Ratio This ratio tells us that how much risk the company is in terms of financial risk and it is used by companies as well as its shareholders to a nalyze the company’s capital structure and leverage (Accounting for Management 2011).

Importance of Learning Styles in Nursing Essay Example | Topics and Well Written Essays - 1000 words

Importance of Learning Styles in Nursing - Essay Example Due to different background, nurses offer a continuum of experiences and attributes during training such as varied learning styles. Therefore, training courses should focus on meeting the particular learning needs of individuals (Young & Paterson, 2007). Every individual shows preference for a particular learning style and this in turn accelerates an individual’s ability to learn. It has been stated that the primary goal of training courses is to upgrade an individual’s functioning; however, little effort or attention goes into appraising training methods. Research about successful training indicates that problem-focuses, pragmatic learning schemes based on skilful clinical monitoring and mentorship should be established. It was also revealed that nurses prefer on the job training; these results were similar to those of another research. It has been demonstrated that passive learning is futile and does not lead to improvement as opposed to active learning. Such research es have shown the need to remodel training schemes to embrace a work-oriented and learner-focused method. A logical approach and reasoning is encouraged by imparting education in practical clinical situation. This clinical setting assists in incorporating theoretical knowledge in actual practice for provision of better care of patients. The potential to learn and further application of this learning into practice plays an integral role in providing quality clinical service. Proficient and highly skilled staff guarantees the well-being of patients. In addition, such competent workforce will have to ability to identify and react aptly to clinical requirements. Incorporation of knowledge, learning styles, conceptions is the cornerstone for establishing an effective learning atmosphere. Thereby, an eclectic model is suggested that would integrate the complexities of individual learning into the association’s practices. Honey and Mumford’s Learning Style Questionnaire The à ¢â‚¬Ëœlearning style inventory model’ presented by Kolb inspired numerous theorists. His model served as the foundation stone for Honey and Mumford’s Learning Styles Questionnaire. The distinguishing element between the two models is that the latter investigates general behavioural predisposition whereas Kolb’s model revolves around straightforward queries. Honey and Mumford advocated that majority of individuals have never put thought into how they acquire knowledge (Honey & Mumford, 2006). Essentially, the two models are similar but with minor differences, for instance the terms of Kolb’s model have been substituted: divergers with reflector, assimilators with theorist, convergers with pragmatist and accommodators with activist (Sims & Sims, 1995). 1. Reflector--- finds lecturers beneficial if they are based on expert expositions and analysis. He is fond of learning through watching, thinking and reviewing over events. He utilizes journals and brainstor ms. 2. Theorist— prefers lectures, case studies, books, structure, standards, and examples. He adopts a step-by-step approach to deal with problems and is not in favour of expert talk. 3. Pragmatist— fond of feedback, teaching and establishes evident ties between ongoing task and a difficulty. He applies novel knowledge to practice; and is inclined towards laboratories, actual work and examination. 4. Activist—
