Social Psychology - Essay Example the study o f how behavior due to one sort of environmental event (larger distant or abstract rewards) may come to dominate behavior due to another sort (smaller immediate or particular rewards)†(Rachlin,2000,p.25).Self discipline is also a concept, which is closely related to self control. It is taming oneself, to live a certain way of life. This concept is mainly incorporated by the person in his life, when he wants to achieve a particular task. Mostly, self control is seen as an individual trait and as a measure of self discipline. If a person lacks self control, it is seen as a failure of his character and personality. Self control is the capability of a person to motivate him to do the right thing. It can also be described as stopping ourselves form doing things that we see as bad for us. Self control constitutes a fundamental aspect of human behavior. Self discipline is another name for self control, without which the life of individuals would lead to chaos. Every habit embedded in the human mind is the result of continuous action .So by controlling a behavior he can form or avoid a habit. It can be very well said that, self control is the strong foundation for the building of character in a person. The degree to which an individual think he has control over the events happening to him, is termed as locus of control. â€Å"Internal versus external control, often referred to as locus of control, refers to the degree to which persons expect that reinforcement or an outcome of the behavior is contingent on their own behavior or personal characteristics versus the degree to which person expect that the reinforcement or outcome is a function of chance, luck or fate, is under the control of powerful other, or is simply unpredictable†(Scrimla,Grimaldi ,2002,p.381).People having high locus of control, have a better control on their behavior and desires. These people direct their life in their own designed path, with their own controlled actions and behavior.

The Contemporary Context of Educational Change Essay Example for Free

The Contemporary Context of Educational Change Essay If there ever was a time in which schools could operate in isolation, that time has long since vanished. There are now many actors and players who would like their say in shaping what is taught, to whom, and how, and who want to take a lead on the education stage. Some will have greater authenticity than others, but none will be capable to lead on their own. The leadership tapestry is multifaceted, rich and ever changing. Leadership is more than a role-based function assigned to, or attained by one person in an organization who uses his or her power to influence the actions of others. It extends beyond the instantaneous school community, embracing those numerous actors on the wider leadership stage—governments, trade unions, school districts and businesses—recognizing the diverse roles which they play. Orton, J. and Weick, K. E. (1990)description of educational organizations as â€Å"loosely coupled systems â€Å"is a third image of the university that still captures the frustrations of deans and college and university presidents who often describe managing change in higher education as â€Å"herding cats†. School leadership is a way of influencing others through communication. Yet it took half a century before researchers stopped up looking at the traits of leaders and began to think concerning the leadership situation itself. Since then a lot of work has been done on how people become leaders as well as how they can best influence followers, how they can develop teacher and student morale, and how they can better the performances of staff members as well as the children they serve. A recent survey of the research agreed on these points: 1. Leadership is not domination or compulsion of others but the encouragement of efforts to achieve communal goals; and 2. Leadership promotes change but it can also oppose change when it feels itself susceptible (G. Egan, 1990, pp. 48-49). The idea of leadership as a network of relationships amongst people, structures and cultures, both within, and across organizational boundaries has been re-affirmed. The numerous actors are drawn together in quest of the education reform agenda: an agenda that has focused to a great extent on schools. Increasingly, governments of different persuasions have shared the belief that the macro-problems of the state and society can be addressed through improving the micro-efficiency of the school. As a consequence, schools have been assigned the task of righting a range of social and economic ills—a role which numerous would argue is beyond the capability of schools to achieve. â€Å"Rising national expectations about schools have been accompanied by reduced teacher autonomy and increasing demands for higher performance—of teachers, as well as of pupils† (MacBeath, Moos and Riley 1996, 223-50). One of the fundamental areas of agreement between researchers who have investigated educational change concerns the powerful impact of head teachers on processes related to school effectiveness and school improvement. Research identifies consistently that those schools which have demonstrated the capacity to improve themselves, tend to be led by head teachers who have made a significant contribution to the effectiveness of their staff. â€Å"Whatever else is disputed about this complex area of activity known as school improvement, the centrality of leadership in the achievement of school level change remains unequivocal† (West Jackson 2001). This should not surprise us—â€Å"it is now more than twenty years since leadership was identified as one of the key components of ‘good schools’ by Her Majesty’s Inspectorate of Schools in England. HMI stated that without exception, the most important single factor in the success of these schools is the quality of the leadership of the head† (DES 1977:36). In particular, the local management of schools has resulted in the head teacher becoming a manager of systems and budgets as well as a leader of colleagues. In addition, the increasingly competitive environment in which schools operate has placed a much greater emphasis upon the need to raise standards and to improve school outcomes. One of the major growth areas of the burgeoning management development field has been head teacher training. While much of this training has been narrowly focused and competency driven, it has nonetheless, reinforced the centrality of the head’s role in leading school development and improvement. This broadening of interest in, and understanding of, the head’s leadership role parallels the pattern of development of leadership theory generally. In the UK the adoption of local management of schools has come from a belief in the relationship between decentralization and enhanced school effectiveness. In particular, the shift towards the self-management of schools has been premised upon the assumption that management decisions are more likely to be effective if they are located within the institution. This emphasis upon ‘self-management’ has been welcomed by many head teachers, primarily because of the possibility it offers for increased control over policies and resources and expanded scope for leadership. â€Å"Management is therefore developing as a significant challenge to improve organizations and has become a key concern of many† (De Long Seeman 2000:33) What starts as freedom to move around budget items and resources, to alter and to develop new priorities, inevitably brings with it new staff management issues. Indeed, it may well be that it is not the technical skills of financial or resource management that we have to assimilate, but the rather more complex interpersonal skills needed to create support for new priorities amongst the staff group. â€Å"There are also evaluating acts, which measure staff decisions or accomplishments against organizational goals and standards. And finally, there is the diagnostic function, which seeks to point out sources of difficulties, problems that need to be resolved, and the steps that need to be taken to resolve them†. (Robert G. Owens, 2004, pp. 176-182). It is here, in the implementation of interpersonal skills in times of difficulty, as well as times of growth, that the leadership individuality of the head teacher will be tested. It may be that the current prominence within head teacher training focuses too much on the technical competencies of management, and not enough on the personal and interpersonal qualities that are expected to be needed as schools take increased accountability for improving themselves. Similarly, this focus on the relationship between leaders and work groups and the ways in which the leader can extend and harness the relationship has been replicated in the development of leadership theory usually—it is not a ‘school’ issue as such. â€Å"It has been widely argued that complex and dynamic changes, such as the ‘cultural’ changes that are required for sustained school improvement, are less likely to occur as a result of transactional leadership† (Burns 1978, Caldwell 1999). A model of leadership more similar with the requirement of cultural change is that of transformational leadership. This approach of leadership focuses on the people involved and their relationships, and needs an approach that seeks to change feelings, attitudes and beliefs. Transformational leaders not simply manage structure, but they resolutely seek to impact upon the culture of the school so as to change it. It has been argued that cultural transformation and all the related complexities that surround school-based change are at the core of school improvement. Consequently, both supposedly and conceptually, transformational leadership would emerge to be consistent with a desire to bring concerning school improvement, rather than just ‘change’ the school. Of course, while the centrality of leadership in this school improvement process is unquestionable, there is a matter over who the ‘leaders’ are in the interest of improvement efforts. There is a rising research literature that points towards the importance of leadership at all levels within the organization. For instance, the leadership role of what might be termed ‘middle managers’ has been recognized as important, for example, in explaining differential school effectiveness (Sammons et al. 1996; Harris et al. 1995). Likewise, there are increasing calls for and recognition of a leadership role for teachers in the context of their own areas of direct accountability. Yet there is some research evidence that suggests that there is an ever-growing segregate between ‘leaders’ and ‘followers’ as a consequence of the changes arising from the self-governance of schools (Wallace and Hall 1994). The strong managerially culture obvious in some schools has resistant the separateness of the senior management team and has claimed leadership as an activity for the few, rather than the many. Schools committed to continuous improvement found that such schools feel constrained by this formulation of leadership as a function of hierarchy and are moving beyond it. Instead, these schools enlarge both leadership and ‘followership’ as generally based functions within the culture of the school. Hopkins et al. 1994 noted that a school that looks to the head teacher as the sole source of direction and inspiration is relentlessly constrained in its development capacity. Yet school structures often support this rather limited view, imposing a hierarchy of roles over the real sharing of knowledge and skills. Most often linked with school improvement. In practice, this means that head teachers give others real authority and assist them to extend to be able to use this authority prudently. This means giving up the idea of structure as control, and viewing structure as the vehicle for authorizing others. But it is not easy to give up control. Even when goals are agreed, it is not all the time easy to trust others to use their own knowledge and skills to take change about. Yet trust is critical to support the leadership climate. The transformational approach is stranded in trust: â€Å"Trust is the essential link between leaders and led, vital to people’s job, status functions and loyalty, vital to fellowship. It is doubly important when organizations are reaching rapid improvement, which requires exceptional effort and competence, and doubly so again in organizations like schools that offer few motivators†. (Evans 1998:183) Labaree (1997) described the educational goals of democratic equality and social mobility as conflicting because they represent competing visions of education and the structure of education. He defined democratic equality as an ideological tradition â€Å"that sees schools as an expression of democratic political ideals and as a mechanism for preparing children to play constructive roles in democratic society† (p. 43). As he explained further, the pursuit of equal access, whereby everyone â€Å"should have an equal opportunity to acquire an education at any educational level† (p. 46), is one form of this goal. This goal has made attending a postsecondary education institution a norm, rather than an exception, for high school graduates. The result, Labaree argued, has been tremendous public funding support designed to open up all levels of education to everyone. Institutional ramifications include â€Å"the proliferation of programs and courses, the search for ways to improve pedagogical efficiency, the concern about enhancing administrative control, and the stress on fiscal parsimony† (p. 46). In contrast, Labaree (1997) defined the social mobility goal as providing â€Å"students with the educational credentials they need in order to get ahead in [the existing socioeconomic] structure† (p. 50). He saw this as an individual goal, rather than a collective goal, like democratic equality, because social mobility emphasizes â€Å"individual status attainment rather than the production of human capital† (p. 51, emphasis in the original). He saw the tension between equal access and social mobility as â€Å"providing an unlimited possibility for education attainment† (p. 69) so long as there is a â€Å"pyramid-shaped occupational structure† (p. 69). Social equity arguments for postsecondary education attainment combine the goals of access and of mobility, despite their apparent conflict. Labaree (1997) acknowledged that these two goals are expressed in â€Å"the market for educational credentials† (p. 71). Within school improvement it is often proposed that cultural transform (which supports new teacher collaborations, new teaching as well as learning processes that, in turn, lead to enhanced outcomes for students) desires to be a central focus of leadership studies. The types of school cultures most helpful of school improvement efforts appear to be those that are mutual, have high expectations for both students and staff, that show a consensus on values, that hold a secure environment and those which persuade all teachers to presume leadership roles suitable to their experience (Hallinger and Leithwood, 1996). In summary, the role of leadership in school improvement is to take about cultural change by altering the processes which occur within the structure and not inevitably to affect the structure itself.

Visionary Leadership In Health Health And Social Care Essay

In much of the underdeveloped universe, there is a broad spread between what has been achieved and what is desired in wellness. Technologies are available to turn to the assorted wellness concerns which may assist in accomplishing the many health-related ends. But this has non happened. The World Health Organisation ‘s ( WHO ) Framework for Action[ 1 ]underscores the importance of beef uping wellness systems to better wellness results. There is a demand to stress the function of establishment edifice in wellness systems in so that entree and quality of available wellness services can be improved[ 2 ]. However, a losing piece of this triangulation of critical factors for accomplishing coveted wellness results may good be found in a airy leading. In Section Two of this chapter, a instance is made for beef uping leading in wellness as the success in bettering wellness has been unequal. Advancement has been slow in accomplishing several health-related Millennium Development Goals ( MDGs ) every bit good as turn toing catching or non-communicable diseases or wellness sector reforms. Most reappraisals of advancement have showed a deficiency of leading and political will, and argued for greater leading that could take to enhanced policy attending and resources which would ensue in targeted effectual plans or accomplishing planetary criterions such as the Millennium Development Goals ( MDGs ) . The demand for beef uping leading is non new or limited to developing states. In 1994, Milbank Memorial Fund organized a meeting around â€Å" leading in public wellness †[ 3 ]. In the debut of the study, Daniel M. Fox and William L. Roper sum up the positions of participants and writers as follows: The writers of these documents agree that jobs of leading contribute to the trouble of doing and implementing policy to better the wellness of the American populace. By leading they mean the capacity of professionals to work efficaciously during long callings in a assortment of organisations that command resources and favourable attending from elected functionaries and the general populace. The writers, along with many of their co-workers among senior public wellness professionals, believe that more effectual leading would better the interlingual rendition of bing cognition about the bar and control of disease into policies that lead to longer and healthier lives. Leaderships can do a difference, as discussed in Section Three of this chapter. A instance of a leader doing a difference in the operation of wellness Centre in a province in India is presented. Many such illustrations abound in the literature[ 4 ]. A recent illustration of leading ‘s function in Senegal ‘s determination to offer free wellness attention is discussed. What do leaders necessitate to make? While a deficiency of equal resources is frequently mentioned as a cardinal barrier to accomplishing better consequences but illustrations in Section Four contradict this. We foremost discuss an illustration where a adult female ‘s life was saved despite gestation complications. The experience of Sri Lanka with cut downing maternal mortality shows what can be achieved in resource-constrained scenes. Similarly, several states have achieved singular success in change by reversaling or forestalling spread of HIV including Thailand, Uganda and Senegal. Practices which led to their success have been analyzed by UNAIDS. We map these patterns through a leading position taking to results of shared vision, aligned values, coordinated practices/ behaviours and leveraged resources of the wellness system. This is the result leaders need to accomplish.Inadequate Progress in Bettering Health: Case for Strengthened LeadershipThe Millennium Development Goal sIn 2000, the 189 United Nations Member States met at the Millennium Summit and adopted eight ends and 18 marks to battle poorness, hungriness, disease, favoritism against adult females, debasement of land, and illiteracy. The universe development community is challenged to accomplish MDGs by 2015. The Millennium Declaration ( paras 11 and 12 ) provinces[ 5 ]: â€Å" We will save no attempt to liberate our fellow work forces, adult females and kids from the abject and dehumanizing conditions of utmost poorness, to which more than a billion of them are presently subjected. We are committed to doing the right to development a world for everyone and to liberating the full human race from privation. We resolve hence to make an environment – at the national and planetary degrees – which is contributing to development and to the riddance of poorness. † Three of the eight MDGs are wellness related ends ( Table 1 ) : kid mortality ( MDG 4 ) , maternal wellness ( MDG 5 ) and HIV/AIDS ( MDG 6 ) . In add-on, gender ( MDG 3 ) is a cross-cutting issue that impacts many wellness issues including the three above. Other MDGs such as poorness and instruction have a strong correlated relationship with the societal determiners of wellness. Table 1. The Millennium Development Goals No Goals 1 Eradicate utmost poorness and hungriness 2 Achieve cosmopolitan primary instruction 3 Promote gender equality and empower adult females 4 Reduce kid mortality 5 Improve maternal wellness 6 Combat HIV/AIDS, malaria and other diseases 7 Ensure environmental sustainability 8 Develop a planetary partnership for development Beginning: UN. The Millennium Development Goals Report 2011Inadequate Progress towards Health Millennium Development GoalsA speedy reappraisal in 2004 reveals that most states were non on path to make wellness related MDGs. Harmonizing to the World Bank[ 6 ], South Asia was off path on six ends: gender equality, cosmopolitan primary school completion, kid mortality, maternal mortality, catching diseases and sanitation. East Asia and the Pacific part as a whole were away path on kid mortality, maternal mortality and catching diseases. Merely about a 4th of all states in the South and East Asia and the Pacific were on path to accomplish under-five mortality rate where merely 9.7 per centum people in South Asia and 17.4 per centum people in East Asia and the Pacific part live in these states. This state of affairs is even worse for maternal mortality, where less than 15 per centum of the states were on path to make this end. Although recent estimations for kid mortality vary, appraisals have highlighted that several states are off-track to accomplish the MDG 4 which calls for a two-thirds decrease in mortality in kids younger than 5 old ages between 1990 and 2015. It is estimated that world-wide mortality in kids younger than 5 old ages has dropped from 11.9 million deceases in 1990 to 7.7 million deceases in 2010, a per twelvemonth diminution of approximately 2.1 % compared to 4.4 % per twelvemonth needed to accomplish MDG 4[ 7 ]. Examination of distribution of annual rates of alteration in under-5 mortality shows that the MDG 4 mark of decrease rate of 4.4 % per twelvemonth corresponds to public presentation of states at the 67 percentile degree ; clearly a stretch mark. This distribution of advancement for kid mortality besides highlights that explosions of rapid diminution are possible. The survey by Rajratnam et Al. ( 2010 ) suggests that, â€Å" For illustration, 66 states have decreased child mor tality by more than 30 % in merely 5 old ages during the period of this survey † . Such singular diminution provides hope that accelerated advancement is possible. These robust estimations of mortality in kids younger than 5 old ages show that accelerated diminutions are happening in several low income states. These positive developments suggest that the advancement can be accelerated in hapless states but may necessitate to turn to leading challenges taking to heighten policy attending and resources which would consequences in targeted effectual plans. The MDG 5 purposes to better maternal wellness with a end of cut downing maternal mortality ratio ( MMR ) , figure of maternal deceases per 100,000 unrecorded births, by 75 % between 1990 and 2015. It therefore seeks to accomplish a 5.5 % one-year diminution in MMR from 1990. The recent UN study[ 8 ]estimated that globally the one-year per centum diminution in MMR between 1990 and 2008 was merely 2.3 % , less than half of what is needed to accomplish the MDG 5. An estimated 358,000 maternal deceases occurred worldwide in 2008, a 34 % diminution from the degree of 1990. The UN Report goes on to state, â€Å" The modest and encouraging advancement in cut downing maternal mortality is likely due to increased attending to developing and implementing policies and schemes aiming increased entree to effectual intercessions. Such attempts need to be expanded and intensified to speed up advancement towards cut downing the still really broad disparities between developing and developed states . † We will subsequently on discourse how Sri Lanka was able to halve their MMR in approximately 7 to 10 old ages and associate it to how leading challenges were addressed. Advancement at this gait in cut downing MMR would hold been equal to accomplish the MDG 5. This clearly shows that much needed leading was non forthcoming. Nowhere is the influence of leading more seeable than for HIV/AIDS plans, peculiarly by people populating with HIV ( PLHIV ) . The consequences are seeable in advancement towards a mark of MDG 6 which aims to â€Å" Combat HIV/AIDS, malaria and other diseases. † The UN study[ 9 ]on advancement towards MDG 6 suggests that against the mark – to halve infections by 2015 and get down to change by reversal the spread of HIV/AIDS – the spread of HIV appears to hold stabilized in most parts, and more people on antiretroviral intervention ( ART ) are lasting longer. The study says, â€Å" The latest epidemiological information indicates that, globally, the spread of HIV appears to hold peaked in 1996, when 3.5 million people were freshly infected. By 2008, that figure had dropped to an estimated 2.7 million. † However, much more is required for quickly cut downing the new infections. Advancement is besides seeable towards the 6th mark – have halted by 2015 and begun to change by reversal the incidence of malaria and other major diseases – mostly driven by external attending and resources as evinced by formation of the Global Fund to Fight AIDS, TB and Malaria. The UN study says, â€Å" Sustained malaria control is cardinal to accomplishing many of the MDGs, and available informations show important advancement in scaling up bar and intervention attempts. † The study concludes, † more attending demands to be given to guaranting success in big states that account for most malaria instances and deceases if the MDG mark is to be reached. † The external influence on big states is likely to be restrained and more vigorous in-country leading is needed to turn to disease load due to malaria. The advancement on TB is edging frontward as incidence rate per capita continues to worsen easy. The UN study concludes, â€Å" If current tendencies are sustained, the universe as a whole will hold already achieved the MDG mark of halting and change by reversaling the incidence of TB in 2004. † However, because of deficiency of entree to high quality attention, TB remains a 2nd of import cause for the figure of people it kills. In 2008, 1.8 million people died from this disease. The MDGs passed the 12th twelvemonth grade in 2012 and there are three old ages to travel before the mark twelvemonth 2015. There has been progress but it has been uneven and patchy. For case, where there have been motions towards accomplishments of MDG marks, there was grounds that leading was vigorous and contributed towards actions for coveted wellness results. So, this is the chance and leading challenge for accomplishing MDGs by 2015.Non-Communicable DiseasesAlthough no specific MDGs were set for non-communicable diseases ( NCDs ) , they are a cause of the bulk of deceases, and the planetary disease load of NCDs is increasing. The Lancet NCD Action Group and the NCD Alliance say[ 10 ]that there is a demand to make a sustained planetary engagement against premature deceases and preventable morbidity and disablement from NCDs, chiefly bosom disease, shot, malignant neoplastic disease, diabetes and chronic respiratory diseases. It proposed five overarching precedence actions for the response to the crisis – leading, bar, intervention, international cooperation, and monitoring and answerability – and the bringing of five precedence intercessions – baccy control, salt decrease, improved diets and physical activity, decrease in risky intoxicants intake, and indispensable drugs and engineerings. The study goes on to state, â€Å" The first cardinal action for success is strong and sustained political leading at the higher national and international degrees†¦ .. Individual title-holders and politicians will besides necessitate to take a leading function. The wellness sector has a prima function in reacting to NCDs but many other authorities sectors including finance, agribusiness, foreign personal businesss and trade, justness, instruction, urban design and conveyance, have to be portion of the whole-of-government response, along with civil society and private sector. † Clearly the wellness plan leading of NCDs would hold to travel beyond their zone of influence to these other sectors.Health SectorHealth sector is confronting many challenges due to medical progresss every bit good as rapid epidemiological and economic passages, although their nature and strength vary from state to state. All wellness systems are fighting to incorporate costs while bettering wellne ss equity. Such a state of affairs, in bend, poses many challenges for leaders of wellness sector. An independent Commission on the Education of Health Professionals for the twenty-first Century called for a 3rd coevals of wellness professionals that should be system-based to better the public presentation of wellness systems[ 11 ]. The acquisition of wellness professionals need to travel from enlightening to formative to transformative acquisition. Enlightening acquisition is about geting cognition and accomplishments. Formative acquisition is about socialising pupils around values ; its intent is to bring forth professionals. Transformative acquisition is about developing leading attributes ; its intent is to bring forth enlightened alteration agents. The ultimate intent is to guarantee cosmopolitan coverage of the high quality comprehensive services that are indispensable to progress chance for wellness equity within and between states. Health sector reforms require non merely top degree political leading but besides leading of wellness sector at assorted degrees. This calls for leading to do a difference in wellness and, thereby, accelerate advancement in accomplishing MDGs.Leaderships Can Make a DifferenceLeaderships can make itCase study 1: Chainpur Primary Health Centre, Jharkhand, India The Chainpur primary wellness Centre ( PHC ) is located about three kilometres from the territory infirmary in Palamu territory of Jharkhand province in India[ 12 ]. In 2006, the PHC was in bad form. Grass had grown in the PHC compound and the manus pump had rusted from non-use. Very few people used the PHC services. Dr. A, medical officer in-charge ( MOIC ) , and his co-worker, Dr. G felt that non much could be done. â€Å" Who will come to Chainpur when you can travel to territory infirmary in 20 proceedingss? â€Å" , they said to a sing squad from an academic institute to discourse engagement of Dr. A in a leading development and organisation effectivity plan ( LDOE ) being launched with support from a giver. Despite his reserves, Dr. A agreed to take part. Through two round tables of preparation and during follow-up by LDOE squad, several thoughts for betterment were discussed and routinely rejected as it was felt that â€Å" non much could be done † . However, Drs. A and G began to experience that something should be done. As a portion of the preparation, Dr. A participated in advanced leading preparation in Malaysia and was inspired by the operation of the Malaysian wellness system during a field visit. Dr. A motivated his co-worker Dr. G that they would seek to better the PHC. As financess were available from the National Rural Health Mission ( NRHM ) , their first effort was to better the so moribund bringing room. Women ‘s feedback was used to better quality of installations and do services user-friendly. For case, payment of inducements for institutional bringing under a national strategy was given before the adult females left for place after bringing. As territory infirmary was nigh, adult females with complications of gestation could be easy referred at that place. Consequently the figure of bringings increased significantly. The layout of outpatient waiting room was improved. Benchs were provided and a little Television and purified H2O dispenser was installed with community part. These and other steps, despite being modest in nature, led the District Health Officer to praise Chainpur PHC and urge other medical officers to see it and detect its operation. A journalist visited Chainpur PHC and wrote about it in a newspaper. This became a theoretical account known as ‘Chainpur Model ‘ in Palamu territory. Take Home Messages on leading: Chainpur PHC What did it take to originate a alteration? What did it take to do a alteration? What were the costs and benefits?Leaderships Can Get It DoneCase Study 2: How did Sierra Leone Provide Free Health Care? On 27 April 2010, Sierra Leone started free wellness attention for pregnant adult females, new female parents, and immature kids. John Donnelly took an in-depth expression at how the war-worn state managed it[ 13 ]. In November 2009, Koroma, the president of Sierra Leone announced at a givers ‘ conference in London that he is originating a free health-care program on 27 April 2010, merely five months off, which coincided with the 49th day of remembrance of the state ‘s independency from Great Britain. Now, one twelvemonth subsequently, the consequences are in: the free health-care program has well increased services for female parents, and peculiarly for kids. The figure of kids treated for malaria, for case, has approximately tripled from the old twelvemonth, a dramatic illustration of how the deficiency of money proved to be a barrier to attention. â€Å" What happened in Sierra Leone was breathtaking † , said Rob Yates, senior wellness economic expert at the UK ‘s Department of International Development ( DfID ) a month after the launch. Yates has advised several authoritiess in Africa on establishing free health-care enterprises. â€Å" In five months, they were able to make a systematic reform in the Sierra Leone wellness system † , he said. â€Å" They had leading that galvanized the whole system. We have n't realized the full importance of what they have done. The planning was more thorough than any I have seen. Other authoritiess can larn from Sierra Leone. † In Sierra Leone, the cardinal factor, harmonizing to those interviewed, was the president: he put the health-care directive at the top of his precedence list. Political will drove the procedure. Although giver community was ab initio loath, they were willing to follow. There were other important factors. The Ministry of Health and Sanitation, which was responsible for execution of the enterprise, was fortunate to hold cardinal leaders in proficient places, such as the main medical officer, the manager of generative wellness services, and the caput of human resources. They took on extra duties at a clip when the ministry was without a curate. This was critical to the success of the free wellness attention program. They motivated people and played the function of wellness diplomat. One of them, although cognizing what had to be done, did non follow a direct nature of taking. It was compromising, warm and friendly. It was, ‘Do you think we could make this? ‘ alternatively of ‘Why the snake pit has this non happened? † Another took on the function of ministry interpreter for free wellness attention. Merely before the launch of free wellness attention, he went on wireless shows and keep imperativeness conferences. Cardinal leaders in the ministry were assigned territories and each travelled to the countries a twosome of yearss before the launch. The attempt to convey free wellness attention to Sierra Leone was non easy or simple, and ministry functionaries readily admit to doing incorrect determinations at assorted points. But to do the enterprise a success, tonss of people worked long hours for months toward a individual end that they believed in.

What were the costs and benefits?Leaderships Know What Needs to be DoneCase Study 3: Woman whose life was saved: Overcoming Adversity at Maternal and Pre-natal Clinic, Tarapoto Regional Health Centre, San Martin[ 14 ] Rosa Diaz Barboza is a occupant of the Tabalosos territory in San Martin. At 18 old ages of age, Rosa was a merrily married adult female settling down to life with her new hubby and life on the farm and anticipating her first kid. Her distant place is located three hours from the closest wellness station, which is merely accessible by pes and even so, when it rains, the route is sometimes wholly out of use and no 1 is able to acquire in or out. However, despite all these geographical troubles, during the first trimester of Rosa ‘s gestation, outreach attempts by the regional wellness Centres were able to acquire to Rosa and she received antenatal instruction and attention. During a everyday prenatal visit, it was discovered that Rosa ‘s gestation could be a high hazard one due to several factors including anaemia. Taking into consideration the possible geographical troubles, deficiency of equipment and qualified staff, Rosa was referred to the wellness Centre in San Juan de Talliquihui where she could be attended to by non merely a nurse but besides a qualified clinical accoucheuse. At the 8th month of her gestation, Rosa and her hubby began the long journey to San Juan which involved a three-hour trek uphill to make the closest route. In San Juan, they stayed with relations and Rosa ‘s hubby picked up uneven occupations to get down salvaging money for the new babe. At the wellness clinic, Rosa was checked every hebdomad and everything seemed to be come oning usually. Nevertheless, clinic staff continuously praised Rosa and her hubby for be aftering in front. In the early hours of 25 June, Rosa began holding labour strivings and the accoucheuse was called instantly who confirmed that she was so in active labour. At 8:30 am, Rosa was transported to the wellness Centre where they were met by the Ob/Gyn Nurse. By 9:30 am, Rosa was ready to give birth but unluckily, the lone comfy bed in the Centre was occupied so, she was forced to give birth on difficult board which made the labour procedure even more painful. At 10:09 am, Luzmirella was born – she took her first breath and allow out a loud cry. She appeared healthy and normal and Rosa seemed to be managing the state of affairs good. Everyone was relieved and Rosa ‘s hubby rapidly ran place for a pillow and cover for his married woman. Forty proceedingss subsequently, the nurse observed that Rosa ‘s placenta had still non been expelled and she was shed blooding somewhat. Concerned by her anterior anaemia diagnosing and, to be on the safe side, she decided to get down the protocol to forestall daze ( low-risk degree ) ( Red ALERT-a really successful series of first assistance protocols for the bar of daze developed by the regional wellness Centre ) and tried to pull out the placenta manually but she was unsuccessful. At that point, she gathered the household members and suggested that they take Rosa to the infirmary in Cunumbuque. This infirmary, located an hr and a half off by auto, has a physician on call 24 hours a twenty-four hours. Initially, Rosa refused to travel stating she would instead decease than be moved in her current status. After bespeaking privateness with his married woman, Rosa ‘s hubby pleaded with her stating if non for him, she had to make it for their kid. At this point, Rosa agreed to the transportation. San Juan is a rural, distant town and as such, community leaders have developed eventuality programs for exigencies. For this state of affairs, they decided to make two things: communicate via CB wirelesss with people populating along the main road to inform them about the exigency and to bespeak a vehicle which can take a piece and, direct person to the infirmary to return with the infirmary ‘s ambulance. Due to the communities ‘ valiant attempts, by 12:30pm, Rosa was on her manner to the infirmary. At this point, she was shed blooding to a great extent and all the nurse could make was go on with protocol, administer injections of saline solution and massage Rosa ‘s venters. Rosa was hectic and non antiphonal, and she slipped in and out of consciousness. At 1:30 autopsy, over 3.5 hours after giving birth, they got Rosa to the infirmary in Cunumbuque. By this clip, she was wholly non-responsive and had lost all centripetal feelings. Doctors at that place instantly transferred her to the operating room where they tried a manual extraction of the placenta, which at this point was half manner out. After 30 proceedingss, the physician decided that Rosa needed specialized attending by a qualified sawbones with the necessary equipment. With IVs in both weaponries to forestall utmost daze due the profuse blood loss, Rosa was transferred once more to the Maternity and Prenatal Clinic and, it was at that place that at 4:00pm, the placenta was eventually extracted and Rosa was given over 4 litres of blood. The physician who finally removed the placenta, said it was due to ALL the actions taken by all the parties involved that saved Rosa ‘s life: from the wellness booster who encouraged Rosa to travel to the wellness station to, the adult male who practically ran all the manner to the infirmary to acquire the ambulance and the nurse who massaged Rosa ‘s belly for 2 hours. The little room where Rosa was instantly moved to was a drab assemblage boulder clay she opened her eyes and asked for her babe. Presently, Rosa and her hubby are be aftering Luzmirella ‘s first birthday party in June. They plan on ask foring all the hospital staff who helped guarantee that Luzmirella, a healthy, boisterous 11 month old can really observe her first and hopefully many more birthdays. Table 1 examines the factors related to the recovery of Rosa. Family/ family, community and authorities wellness system non merely coordinated their responses but besides leveraged resources available to them. These in bend were guided by shared vision about life being cherished and valued maternal wellness.Table 1. Success Factors related to the Recovery of RosaIndividual/ HouseholdCommunityGovernment Health SystemVision Woman ‘s life is cherished Save life when there are gestation complications Save life Valuess Proper wellness attention can salvage life during gestation complications Pregnancy complications need to be addressed Continuum of attention Practices Stay near the wellness installation when gestation was due Implement a eventuality program Health suppliers, nurse, physician all do that is needed Resources Family contributes its resources Community members contributes its labour. Health system uses all available resources The above illustration shows that shared vision, aligned values, coordinated patterns and leveraging resources among individuals/ families, communities and wellness system can cut down maternal deceases. Achieving these is the map of leading as discussed below. Case Study 4: Reducing Maternal Mortality in Sri Lanka[ 15 ] It is good known that engineerings to accomplish health-related ends are available. However, resource deficits are frequently cited as barriers to accomplishing them but the World Bank survey of success of Sri Lanka ( Pathmanathan et. Al. 2003[ 16 ]) in cut downing maternal mortality illustrates importance of wellness systems development and the function of institutional development in bettering entree and quality of available maternal wellness services. The 5th MDGs of bettering maternal wellness has a mark of â€Å" Reducing the maternal mortality ratio by three-fourthss, between 1990 and 2015 † . Based on experiences in Sri Lanka and Malaysia for more than 5 decennaries, the World Bank survey concludes that â€Å" maternal mortality can be halved in developing states every 7 to 10 old ages † . So the above MDG is accomplishable, although the overall advancement in cut downing maternal mortality since the 1890ss, as we saw in Section 2 falls short of the end. What will it take to accomplish this MDG? The Sri Lankan survey shows that maternal mortality decrease is low-cost regardless of income degree and growing rate. The route to maternal mortality decrease fundamentally includes skilled birth attending during child birth, direction of exigencies and complications of gestation and kid birth, and supervising maternal deceases. The critical schemes of wellness systems development used by Sri Lanka for cut downing maternal mortality ratio is shown in Figure 1. It comprised: constructing a foundation for effectual pregnancy attention, taking barriers to entree and bettering use of available installations. The needed institutional alterations in nucleus and complementary establishments are: human resource development and direction, aiming the hapless, constructing a functional referral system, taking barriers to entree furthering community mobilisation, beef uping answerability, and better organisational direction including execution of progressively sophisticated monitoring system. Coincident betterments in back uping establishments through improved conveyance increased seasonably entree. The enabling establishments besides played a function. The early additions in female instruction and the authorization of adult females through the electoral procedure provided an environment that sustained political and managerial committedness to bettering maternal wellness every bit good as improved wellness attention seeking behaviour. Fiscal barriers to pregnancy attention were removed by the authorities ‘s political committedness and society ‘s outlooks of wellness and instruction services to be provided free of charge. Oversight establishments are besides known to hold complemented these attempts synergistically. Civil enrollment of births and deceases was governed by statute law, and maternal deceases were viewed with sufficient concern to justify particular coverage by the Registrar General. Figure 1 shows the conventional position of wellness system development for cut downing maternal mortality. However, as shown in Table 2, these can besides be seen from a leading position of making shared vision, alining values, organizing patterns and leveraging resources among individuals/ families, communities.Figure 1.

In 1998, it had 21 million people, with less than 14 % life in metropoliss. The gross national merchandise per capita was tantamount to about US $ 240. Entire HIV prevalence among grownups was over 8 % . Fortunately, Uganda is besides one of the African states where the HIV epidemic was recognized comparatively early and so prevention attempts were started on a national degree.[ 18 ] In 1986, the President publically acknowledged the state ‘s HIV/AIDS job and made a committedness to mobilising attempts against it. A national budget for the AIDS plan was established early in the epidemic. The state adopted a multi-sectoral attack. The Uganda AIDS Commission was set up in the Office of the President, and HIV/AIDS control plan were established in several authorities ministries, including the Ministry of Health. Different degrees of society were involved such as political, community and spiritual leaders. The Islamic Medical Association of Uganda supported community instruction on HIV/AIDS throughout the state, including the distribution of rubbers.[ 19 ]Radio messages on HIV/AIDS were broadcast widely. Condom societal selling services, backed by USAID, were implemented countrywide. HIV voluntary guidance and testing was made available extensively and outside the formal health-care service. Uganda ‘s success in HIV bar can be seen from the followers: Percentage of grownups infected declined from a extremum of approximately 14 % to approximately 6 % in 2003. Steep addition in rubber usage – the proportion of work forces who said that they had of all time used a rubber rose from 15 % to 55 % . Among adult females, the sum rose from 6 % to 39 % . Behavior alteration – Percentage sexually experienced work forces at age 18 fell from about 90 % in 1989 to 50 % in 1995.SenegalMuch has been written about the demand to step in early to halt the spread of HIV before it spreads to the general population. Senegal ‘s HIV bar plan has been extended and contains the elements of an effectual plan. There is good grounds that Senegal has maintained one of the lowest rates of infection in sub-Saharan Africa by altering the behaviour of many of its citizens.[ 20 ] Like Uganda, Senegal is non a rich state. In 1998, it had 9 million people, with 44 % life in towns. Per capita income was below US $ 600 a twelvemonth. Entire HIV prevalence among grownups was estimated at approximately 1.8 % . Senegal has long emphasized bar and primary wellness attention. Generative wellness and kid wellness are well-established precedences. In add-on, registered sex workers are required to hold regular wellness cheques, and are treated for any curable sexually transmitted infections ( STIs ) that are found. What was the response in Senegal? As in Uganda, politicians in Senegal were speedy to travel against the epidemic once the first instances appeared in the 2nd half of the 1980s. Since 93 % of Senegalese are Muslims, the authorities made attempts to affect spiritual leaders. HIV/AIDS became a regular subject in Friday discourses in mosques, and senior spiritual figures talked about it on telecasting and wireless. Many other degrees of Senegalese society joined in. By 1995, 200 NGOs were active in the response, as were adult females ‘s groups with about half a million members. HIV bar was included when sex instruction was introduced in schools. Parallel attempts reached out to immature people who are non in school. HIV voluntary and confidential guidance and proving were made available. Plans were instantly put in topographic point to back up sex workers to carry their clients to utilize rubber. Sexually Transmitted Infections ( STIs ) moved up the list of wellness precedences. Senegal was one of the first states in Africa to set up a national STI control plan that integrated STI attention into regular primary wellness services. Senegal ‘s success in HIV bar can be seen from the followers: HIV prevalence among pregnant adult females was merely over 1.4 % at the terminal of 1996, with no important tendency over clip. Condom distribution rose from 500,000 pieces in 1988 to 7 million pieces in 1997. Median age at first sex for adult females in 1997 for 25-29 old ages age group was 17.7 old ages but increased to 18.7 old ages for 20-24 old ages age group. Clearly, much in the societal construction and wellness services of Senegal before AIDS favored a successful response. In add-on, strong political committedness and the execution of effectual bar activities helped maintain Senegal ‘s rates of HIV infection among the lowest in sub-Saharan Africa.SiamFew states show the nexus between behaviour and HIV infection every bit clearly as Thailand.[ 21 ]Overall, behavioural alterations have reduced the figure of new HIV infections each twelvemonth from about 143,000 in 1991 to 29,000 in 2000. Thailand has a little over 60 million people, approximately 20 % of whom live in metropoliss. The gross national merchandise per capita was tantamount to about US $ 2700 in 1998. HIV prevalence among grownups was estimated at approximately 1.9 % , with higher prevalence in certain geographical countries and among certain groups. Thailand ‘s HIV prevalence is lower than that of Uganda, but it means a similar figure of people populating with HIV/AIDS. The effectual countrywide bar plan, which began in 1991, included several elements: The Prime Minister chaired the National AIDS Program. The Office of the Prime Minister took an active function in policy treatment, led the national public instruction attempt utilizing government-run mass media ( that is, public, non private ) , and took portion in monitoring. The Parliament established a sub-committee on AIDS. The National Economic and Social Development Board worked closely with the Ministry of Public Health to incorporate the National AIDS Plan into the five-year National Development Plan. The authorities AIDS budget increased drastically during the undermentioned old ages. Each cardinal ministry had its ain AIDS program and budget every bit good as a individual as the AIDS focal point. All provincial governors led the AIDS plan in their several states through the provincial development planning system. The concern community, people populating with HIV/AIDS, spiritual leaders and other community leaders became really involved in lending to policy duologue, resource mobilisation and the local execution of activities. In Thailand, 1991 was the turning point on human rights protection for PLHIV. HIV was removed from the list of diseases that required presentment to the wellness authorization. The prohibition on entry to Thailand of people with HIV/AIDS was lifted. A set of national policy guidelines to protect the rights of PLHIV was issued.[ 22 ] The most dramatic consequence of the national plan, famously known as 100 % rubber plan, can be seen from the followers: Entire figure of people populating with HIV/AIDS decreased from about 750,000 in 1995 to 650,000 in 2000. Work forces aged 15-49 sing sex workers dropped from 19 % in 1990 to 9 % in 1993. Reported figure of STIs in male fell from about 200,000 in 1989 to less than 20,000 in 1994. Consistent rubber usage among sex workers increased from over 50 % in 1990 to about 90 % in 1996.It Can Be Done: Conventional PositionTo show that success can be achieved even in resource-poor scenes, the experiences of these three states with differing civilizations and different degrees of the epidemic are discussed here. Uganda was difficult hit throughout the 1980s, and has had about two million cumulative AIDS-related deceases since so. Senegal, on the other manus, had non been earnestly affected by the epidemic. In Thailand, the epidemic became outstanding merely at the terminal of the 1980s but spread quickly once it took clasp. These are three different state of affairss, but behavioural alteration and some containment of the epidemic were achieved in these three developing states even with resource restraints. What are some indispensable characteristics of effectual plans which are shared by the three states? In each one, national AIDS plans portion a bundle of common characteristics that UNAIDS respects as â€Å" best pattern † , viz. : strong political committedness at the highest degree to covering with the epidemic ( this ensures policies and funding to turn to the epidemic ) ; multi-sectoral attacks to bar and attention and, at authorities degree, engagement by multiple ministries ; multilevel responses ( at national, provincial, territory and community degrees ) ; effectual monitoring of the epidemic and hazard behaviours, and airing of the findings both to better policies and plans and to prolong consciousness ; a combination of attempts aimed at the general population and focused on groups at high hazard, at the same clip ; execution on a big graduated table ; and integrated bar and attention. These actions proved to be effectual because leading was involved. The influence of leaders at different degrees of society in each state – the President/Prime Minister, the ministry functionaries, spiritual and community leaders, and so on – was seen in the bringing of policy waies and plan intercessions harmonizing to the desired or articulated ends and aims. The above actions can be interpreted from the leading perspectives as shown in Figure 2.Figure 2. It Can Be Done: Leadership PerspectiveCreate shared visionUganda: Public recognition, political committedness. Senegal: Political committedness, engagement of spiritual groups. Siam: Engagement of Prime Minister/ Parliamentarians and Provincial Governors.Align Valuess:Uganda: Public recognition, political committedness. Senegal: Political committedness, engagement of spiritual and many other groups including NGOs. Siam: Removing stigma and favoritismCoordinate Practices:Uganda: Multi-sectoral attack, IEC, rubber – societal selling and free distribution, Voluntary guidance and proving centre ( VCT ) . Senegal: Schools, VCT, rubber for sex workers, national STI plan. Siam: Engagement of provincial authorities and concerns.Leverage resources:Uganda: Multi-sectoral attack, political committedness. Senegal: National STI plans. Siam: National and provincial authorities budget, concern Therefore, the success of policies and plans is reflected through leading actions of making a shared vision, alining values, organizing patterns and leveraging resources among the individuals/ families, communities and wellness system, as shown in figure 3 belowFigure 3. The Leadership position for superior consequencesAs the context alterations, the leaders need to continually work on these actions to guarantee sustained advancement. The above mentioned early successes in HIV plans were non needfully sustained in go oning decrease in grownup prevalence of HIV infections. The HIV prevalence in Uganda had stabilized at between 6.5 % and 7 % since 2001. The grownup HIV prevalence remained low in Senegal at 2 % or under. On the other manus in Thailand, the rate of new HIV infections decreased by more than 25 % between 2001 and 2009. Current grownup HIV prevalence is estimated to be near to 1 % , a important diminution from a peak rate of about 2 % in 1995.

chromosomal testing in humans essays

chromosomal testing in humans essays Chromosomal testing in humans, limitations and ethical implications In this credit assignment I have discussed the hot topic Chromosomal testing in humans. The limitations of the technology and its ethical implications and the present discussion going on is also discussed. The chromosomal basis of inheritance Mendel produced his results and hypothesis in 1866 in a journal, The Proceedings of the Brunn Natural History Society. At that time when it was sent to scientific societies all over the world, they all failed to comply with his theory because at that time they were all unable to relate the fact that hereditary factors could be transmitted from parents to offspring with the physical structures of the gametes, which they could observe. By 1900, due to the improvements in technology and advances in cytological techniques, the behaviour of chromosomes in the gametes and gametes were observed. Later two scientists Sutton and Boveri proposed that chromosomes were the carriers of Mendels factors, what we call today chromosome theory of heredity. This theory suggests that a pair of chromosomes carries each pair of factors with each chromosome carrying one of the factors. Johannsen later replaced the term factor, in 1909, with the term gene which is an alternative forms in which an allele may exist and occupy the same loci on homologous chromosomes. It is because of this development in the past that today we are able to carry out the so-called DNA testing and verify so many things. Now we know that hereditary characters are transmitted form parents to offspring through the genes in the gametes. In reproduction, the germ cells from the parents contain haploid chromosomes and upon reproduction the offspring is diploid. Chromosomes from the parents and the alleles in them determine the phenotypes of the offspring. In such a situation, the hereditarily carried diseases such as haemophilia a ...

Why We Sleep & The Necessity of Dream Sleep essays

Why We Sleep & The Necessity of Dream Sleep essays We sleep for a number of reasons; behavioral advantages, metabolic restoration, development, learning information, and for evolutionary protective reasons. Basically it boils down to two theories: physiological theory and cognitive theory. Physiologically, the sleep-wake cycle has a biological rhythm that activates various brain centers, producing activity. While asleep, usually during dark hours, we give our bodies a time to rest and recoup or rebuild to prepare for another day. It is easier for our bodies to perform and see to do things during daylight hours, therefore, we are also protecting ourselves. With the cognitive theory, dreams are a way of learning and thinking, mnemonic in nature. Dreams are believed to use our bodys down time to associate the pieces of information that havent been associated to anything previously. Id say it is a form of house cleaning. Dreaming is believed to be instrumental in memory retention and consolidation. Top scientists, however, have extremely varying visions of what occurs during sleep. A study on the role of REM sleep and memory retention and consolidation was performed by Harvard Medical School. Robert Stickgold, a professor at the Department of Psychiatry at Harvard Medical School, published research that he believes provides compelling evidence that the mind works hard during sleep. They had two groups of students participate and taught each of the students the same material. One group slept as normal without interruption, but the other group was not allowed any REM sleep. The deprived group had far less retention of the material than did the group that was allowed REM sleep. According to this study memory is closely linked to REM sleep. Memory works two ways: to store important information and to remove trivial information. "The brain is taking information and helping us put it into a form that we can understand," Stickgold said. "Understanding the ...

7 Military Ranks Common in Popular Culture

7 Military Ranks Common in Popular Culture 7 Military Ranks Common in Popular Culture 7 Military Ranks Common in Popular Culture By Mark Nichol 1. Captain This all-purpose title, originally identifying the leader of any band of warriors but later formalized to refer to someone holding a specific military rank, is used in civilian contexts to refer to a sports team’s most prominent member, a successful businessperson (â€Å"captain of industry†), or any leader. The rank originated with land-based forces but was carried over in naval contexts when military leaders took nominal command of ships for naval operations or ferrying of troops from one place to another, though the master of the ship the owner or owner’s representative, who unlike the captain had nautical skills actually supervised the ship’s operations. Now, any boat owner or operator is called a captain, and the commander of a naval vessel is referred to as the captain (or, less formally, the skipper) regardless of actual rank. 2. Colonel Was Colonel Sanders, founder of the fast-food chain KFC, a military veteran? He did serve briefly in the US Army, but as a lowly private. So, where did he get his title? From the Commonwealth of Kentucky, it turns out; the Bluegrass State awards the honorific â€Å"Kentucky colonel† to selected individuals who in some way contribute to the state’s well-being. But why â€Å"Kentucky colonel†? After the Revolutionary War, aristocratic landowners who had been commissioned as colonels in the Continental Army and authorized to form regiments were thereafter referred to as â€Å"Colonel† to honor their participation in that glorious conflict. Because such men were community leaders, by extension, the honorific, and in Kentucky the more specific phrase, was later bestowed on wealthy gentlemen in general, whether they had actually held a colonel’s commission or not. This tradition intensified after the American Civil War, when, as before, it was a point of honor to be able to identify oneself as a veteran especially one who had been a senior officer. The title became a routine honorific for wealthy Southern men, even those born in succeeding generations. Colonel Sanders, though of humble origins, adopted this persona after the governor of Kentucky awarded him the title. (A similar, tongue-in-cheek designation is â€Å"Nebraska admiral† a jocular nod to the fact that the Cornhusker State is landlocked.) 3. Drill Sergeant Noncommissioned officers assigned to train recruits, depending on the particular branch of the military in which they serve, have different designations, but this title, for US Army trainers, is the one most familiar to civilians, and it is often used in nonmilitary contexts to denote a harsh taskmaster. This characterization comes from the formidable personalities drill sergeants and their ilk display, because their job is to break their recruits so that their individuality is subsumed to develop unquestioning obedience and unit cohesion, two necessities for group survival in combat. 4. Ensign Originally, ensign referred to a flag, and sometimes the rank of the junior officer assigned to carry a military unit’s flag in battle was given the same name. By extension, though ensign is no longer a rank in land-based military forces, it became the entry-level officer rank in navies, though that officer’s duties have nothing to do with flags. 5. Lieutenant This term, from the French words meaning â€Å"in place of,† originally referred to the deputy of a military leader and later came to be formalized as a military rank (with variations). Like captain, it was then extended into nonmilitary contexts to refer to any immediate subordinate. A similar word is subaltern, an obsolete junior rank corresponding to a lieutenant; the term, though rare, has the same nonmilitary connotation. 6. Major Why is the leader of a marching band called a drum major? Such ensembles are descended in concept from military marching bands, which evolved from the use of bugles, fifes, and drums to sound signals to military units because shouted orders, hand gestures, signal flags, and other forms of communication might be difficult to hear or see in the noise and confusion of battle. Civilian marching bands, whose uniforms are a carryover from military dress, originally were primarily seen in parades, but performances at sporting events, stand-alone events, and band competitions began to predominate. The title of drum major an appointment, not a rank in the military hierarchy carried over to civilian usage; as with military ensembles, the person in that position, who may serve as a conductor, a marching coordinator, or both, wears a distinctive uniform to be easily recognizable. 7. Marshal This word sometimes used in place of or in addition to general in the military hierarchies of some countries, referring to a very high-ranking officer, has lowly origins: It is from a Germanic term meaning â€Å"stable boy† or â€Å"stable servant.† (The first syllable is a cognate with mare, meaning â€Å"female horse†). In medieval society, the humble stable keeper’s status steadily rose until the title referred to the commander of a feudal lord’s cavalry. Ultimately, the term â€Å"field marshal† referred to the leader of an army or a large division of it. The law enforcement term derived from association with a military marshal’s role in keeping the peace, and the use of â€Å"grand marshal† to designate an honorary parade leader stems from the military officer’s duties in ceremonial traditions. (Similarly, constable, which developed from a Latin term meaning â€Å"count of the stable,† was used throughout history from the later days of the Eastern Roman Empire as a title for various high-ranking officials, but constable now usually refers to a low rank in law enforcement.)

Write a research-based, argumentative paper on a topic of your Research

Write a -based, argumentative on a topic of your choosing - Research Paper Example Anti-abortionists insisting that the fetus has a right to life just as the mother has a right to live. The opposing side, those who support abortion, argue that since a fetus relies mostly on its mother for sustenance and development over the months prior to its birth, then the life of the fetus does not exist yet and as such, cannot be considered to be a separate life from its mother. Therefore, abortion is a decision that a woman can and must undertake for her own personal or medical reasons. To have laws that ban her right to free herself of the fetus via abortive means violates her rights as a woman and her right to choose. This essay will look into the reasons as to why banning abortion is a violation of womens rights and why those who oppose abortion directly violate the Reproductive Rights of Women. According to Frederica Matthews - Greene, abortion must be opposed because it violates the right of a woman to protect her body. She claims that â€Å"That right must begin when her body begins, and it must be hers no matter where she lives — even if she lives in her mother’s womb. The same holds true for her brother.† 1 In this line of thinking, it would appear that the right of a woman to her body ends the moment that she conceives a child. Regardless of whether that conception is expected, wanted, or the product of an accident or a crime. In the minds of anti-abortionists, a woman no longer has a right to her body because of the second resident in the womb, who takes precedence over her own safety and concerns. This is an argument that is flawed in every manner. If the life of the fetus does not begin until the umbilical cord is cut and the first cry comes with its first life giving breath, there is no life to actually consider within the womb as the life of what is within relies solely on the existence of the mother and her ability to sustain a secondary life within. Let us remember that the right of

A Report of Community Engagement Essay Example | Topics and Well Written Essays - 500 words

A Report of Community Engagement - Essay Example For anyone who has never experienced a Relay for Life event, it is an amazing event that allows for people to come together who have in some way been touched by cancer. There is not one single person who has not been somehow directly or indirectly been affected by cancer. This event allows for people to come in to celebrate the lives of the survivors who have fought cancer and to remember the loved ones who have lost the battle. Money is raised for Relay for Life prior to the event and during it with all types of activities. In this case, I was a member of a team for Relay for Life and for each team, one person is supposed to walk around the track at all times during the 24 hour long event. By doing this event, I felt as if I was able to give back by both raising money and by contributing my time to help raise awareness about cancer. I participated in this event because I felt a tie to it and a need to feel the social responsibility. Since cancer affects so many people that I have kn own in my lifetime, it only seemed like the best way to try to commemorate how they impacted my life, not just during their lives, but unfortunately, at the time of their deaths as well. There was not a single part of me that did not want to somehow give back.

Critically think about the drop in crime in the US at the end of the Essay

Critically think about the drop in crime in the US at the end of the nineties - Essay Example There was another hypothesis developed that the drop in crime rate was due to the introduction of the Three Strikes Law. This allocation provided that any felony criminal who was arrested on a third offence would be sentenced to life imprisonment (Rushefsky, 2007, 535). The first of the states to allot this was the State of Washington, subsequent steps to continue with this step taking place in Colorado, Arkansas, Nevada and so on. This practice has led to a general reduction in the rate of crime n the United States, with the year 2010 being the safest moments of all. With the homicide division having the lowest record of crime, there has been a decline in other divisions such as violent crimes, rape and robbery. (Press 2010, 135) In conclusion, there are two hypotheses describing the decline in the rate of crime in the United States. The introduction of the Three Strikes Law and the legalization of abortion have contributed to the decline in crime in the United States (Wilensky, 2002, 235). However, there has also been overall improvement in the administration of

Gender Differences in Love and Intimacy Research Paper

Gender Differences in Love and Intimacy - Research Paper Example Notions related to love covers admire, want, having a preference, possession, care for, service, and even reverence. Intimacy denotes a close bond where reciprocated respect, encouragement, and confidence are shared to the partners (Oxford Dictionaries, 2009). Gender Differences Theorists have put forward that men and women differ, in the types of sentiment, they experience while in close relationships. The strength of the sentiments and how willingly they put across those emotions also varies a lot. A number of theories, starting with evolutionary theory, cognitive social theory, social structural theory as well as gender hypothesis all concur that there is gender difference between men and women regarding sexuality. Men are normally more sexually active as well as more liberal as opposed to women. Cognitive theory, social structural theory, and social learning theory suggest that sexual difference observed between men and women could be reduced by aspects like secular trends and cultural behaviors towards gender empowerment and multiculturalism disparities in sex roles, which ought to differ with each culture. As noted by Petersen and Hyde (2010) it is possible that methods from various theories assist in the complex explanation of this gender differences in intimacy and sexuality. Men watch close relationships as less weighty than women do. Cultural theories suggest that women feel love for people while men labor. This concept has been put forward by an extensive variety of psychologists and sociologists.

The title to be used when submitting this assignment is Materiality in Essay

The title to be used when submitting this assignment is Materiality in Auditing - Essay Example Therefore, an auditor has to set a materiality level for important and vital aspects of the audit in order to concentrate and focus on the areas that are important and necessary. The Financial Accounting Standards Board (FASB) defines materiality as â€Å"the magnitude of an omission or misstatement of an accounting information that, in the light of the surrounding circumstances, makes it probable that the judgement of a reasonable person relying on the information will have been changed or influenced by the omission or misstatement† (Johnstone, et al., 2013 p268) This implies that materiality is about the important issues and matters which when overlooked, will cause the financial statement to be overly misleading. Therefore, in the auditing context, materiality involves a situation whereby the auditor examines and reviews important things in his analysis of the financial statements in order to ensure that the opinion they pass on the financial statement are valid and reliable. Materiality affects sample sizes and determines whether the financial statement needs adjustments or not, and it represents the difference between a qualified and an unqualified report (Bagshaw & Selwood, 2013). This shows how the auditor can estimate the levels of issues that matter and then define the way and manner in which work can be distributed and conducted throughout the entire audit. This therefore means that materiality informs an auditor of which aspects of the financial statement amounts are to be given certain levels of attention. This gives the auditor guidelines on how to evaluate and analyse things and the extent to which focus should be given to certain components of the financial statement. Materiality is to be defined on a case-by-case basis. It involves the integration of professional judgement. It is done by examining the entire financial statement as a whole and this will help the

A Critical Examination of Business Set Up Opportunities in USA from A Essay

A Critical Examination of Business Set Up Opportunities in USA from A Company Perspective - Essay Example A number of forces drive organizations into expanding their operations to the foreign markets. Increased competition in the local and foreign markets as well as reduced trade barriers are some of the factors. The international business environment is quite dynamic and a business organization that has to survive in its international operations has to respond to the changes. The strategic business planning to manage this dynamics involves an examination of the bargaining power of the buyers, the bargaining power of the suppliers, the magnitude of rivalry, the other product or service substitutes, or the threats of other new entries into the market. The vending business is not a new practice in the United States, the first machine of this kind being developed as early as the late nineteenth century. The changing patterns are observed in the quality and types of products offered as well as improvement in the vending machines to ensure security and efficiency. Most recently, there have be en shifts towards high capacity vending machines that can vend healthy juices, yoghurt, fresh fruits, or vegetables. Investment in the healthy vending machine can be incredible in the contemporary society if proper strategic planning and management is carried out. The vending machine business is quite appealing to many individuals in the contemporary markets. The business has several associated benefits to the investor. It is characterized by immediate cash flows, all-cash business (no debts or accounts receivable), can operate 24 hours a day everyday, and it needs little expertise in business management or sales and marketing . The clients in this industry require quick service and ‘demand immediate result making fast food too slow. [The] vending machines provide an affordable quick snack’ (Vending Man, 2011b). The clients give more value to healthy vending that produces healthy foods and with no negative long-term effects on the health of the clients. The business is a fun industry that can generate high returns with little investment since it requires few employees (Vending Man, 201 1a). An individual can supply and manage millions of these machines at different locations with the little task of putting in food occasionally, after every few weeks. This report focuses on these opportunities and the establishment strategy for vending machine business in the US market. The socio-political and economic factors in the US market as well as the business strategy to be employed in this business are illustrated. The US market- Environmental analysis The factors external to our organization like laws and regulations in another country, the country’s economic profile, national culture, and market competition affect the decision to establish business in the country (Mead, 2005). Economic analysis The United States is among the countries that suffered the financial crisis and the resulting economic problems that have been experienced globally (Jickling, 2010). Nonetheless, the Federal Reserve and other government agencies like the US Treasury have shown relentless ef forts to restore the situation through improving the financial systems (Marshall, 2009). It is then likely that the buying ability of the US citizens will be improved giving hope for a new business opportunity. Socio-cultural influence The socio-cultural factors in the country also favor the investment in food industry with focus on healthy eating habits. The consumption of soft drinks has been high in the United States in the past and yet these foods have negative impacts on the consumer heath (Jacobson, 1999). The soft drinks add unnecessary calories to the diet and

Using the Right Storage Device at the Right Time Essay Example for Free

Using the Right Storage Device at the Right Time Essay The advent of technology enabled us to have an easier and more comfortable life. Computers have been assisting us in almost all of our daily tasks, from typing to storing our files. Due to the ever developing computers and programs, files have evolved into different forms and sizes. This eventually led to the different forms of storage devices that are applicable to certain storage requirements. There are different classifications of storage devices depending on their access, memory retention and mode of data storage. The first classification is based mode of access by the central processing unit; and these are the primary and secondary storage. Primary storage, also called main storage or memory, is the part in a computer where data is kept for quick access by the CPU. In personal computers and laptops, it is most commonly called as the random access memory or RAM. Meanwhile, secondary storage, also known as auxiliary storage, is the data storage device not used as the primary storage. It is also known as external storage. Examples of this are hard disks, floppy disk, CD’s, DVS’s, magnetic tapes and flash drives (Search Storage, 2005). Another classification is based on memory retention. Volatile storage devices are those that do not retain data when the computer is shut down and an example of this is the common RAM. On the other hand, non-volatile storage devices are those that retain data even in the absence of a power supply and examples of these are hard disks and CD’s (MSD, 2006). The last type of classification is based on the mode of data storage and these are the magnetic and optical storage. Magnetic storage devices use magnetic disks that contain iron particles which can be polarized into a direction by a magnetic charge. The organization of the particles creates the data that is stored on that disk. Meanwhile, optical devices are high-capacity storage devices that uses reflected light in reading data. To store data, the metallic surface of the disc is covered with small dent (or pits) and flat (or land) spots. When the light is directed into a pit, the light is not reflected back thus there is a bit value of zero (or off) and when the light is directed to a land, the light is reflected, thus having a bit value of one (or on). The arrangement of these lands and pit determines the data stored (CM Lab). Due to the many forms of these storage devices, it is appropriate to know what situations are deemed fit of unfit for a specific type of storage device. In choosing a storage device for a certain job, it is important to take note of some items to ensure the use of the proper storage device. These include knowing how much data is needed to be stored, how fast data should be recovered, what storage devices are available, how automated the data storing process is and how fats the data could be stored (HP). These should be kept in mind in order to optimize your time and your back-up system. Random access memories or RAM’s are the primary memory of the computer. It is the memory used by the operating system of the computer when booting. After the boot, the other areas of the RAM unoccupied by the system become the conventional memory which the computer uses in running programs (MSD, 2006). The advantage of RAM is that if it is increased in a computer, it speeds up the processing of the computer enabling the user to use multiple applications. However, its disadvantage is that it is unusable once the computer is shot down. This means that RAM’s are applicable only in speeding up the processing of the computer and not in data storage. Hard disks are secondary storage devices that are used as the primary data storage of most computers. It is usually consisted of a number of inflexible platters that stores data electronically. The advantages of hard disks over other data storage devices include huge storage capacity and fast access time, cheaper on per megabyte basis and are more reliable since they are better protected and are made to be more durable. However, they still have disadvantages, such as non-portability (for installed drives), less security of data due to vulnerability to virus attacks and head crash due to contaminants and extreme shocks (Wong). This means that hard disks are efficient only on storing of huge data for relatively short periods of time. Floppy disks are flexible plastic disks that are coated with magnetic material use to store data magnetically. It is most commonly known as the diskette. They are very popular in the 1990’s, however, they not anymore considered standard today due to its more efficient alternatives (MSD, 2006). The advantages of diskettes include portability and cheapness, random access of data, write-protection feature and ease in transferring data from one computer to another. However, it also has its disadvantages, and these are its non-durability, slow access time and very limited storage capacity (Wong). This means that diskettes are appropriate only for small and temporary data storage. Compact disks are optical devices that stores data. They use microscopic pits and lands in storing data. Their advantages include portability, relatively large storage capacity, a relatively fast access time, and permanent data storage. Meanwhile, its disadvantages include its non-reusability and relatively slow writing time (Wong). This means that CD’s are more applicable in storing permanent data that requires no editing such as software installers and audio files for longer periods of time. Magnetic tapes are strips of plastic coated with magnetic material and are capable of storing huge amounts data. Their advantages include huge capacity, cheapness, reliability and universality; and its disadvantages include sequential accessing and frequent cleaning (MSD, 2006). This means that tapes are more appropriate for backing-up huge amounts of data for relatively long period of time. Flash drives are storage devices that used flash memories or chips to store electronic data. They are the new form of data storage devices. Its advantages include compactness, portability, fast data writing and access and consists no mobile parts. Its disadvantages include expensiveness and limited data storage (MSD, 2006). This means that flash drives are more appropriate in storing medium size data that needs to be transported or transferred to other computers.

The Study and Findings of Climatology in Nepal Essay -- Climae Environ

The Study and Findings of Climatology in Nepal In many areas in Nepal, the history of climatology only dates back to 1956. Around this time, the Indian Meteorological Department instituted stations in various areas around the country, which were eventually taken over by the Nepalese government in 1966. Having these stations in place has given scientists significant insight into the Nepalese climate. However, some of the Indian equipment remained in the Nepalese stations, and unfortunately many Indian findings vary significantly from the Nepalese records of the same areas. Therefore, some information is unreliable, coupled by the fact that not all stations have operated since the start of the program (Thyer, 645). However, there are other sources of NepalÕs climate history, like extracts from articles written by climatologists from other countries, like Japan, the US, Germany, and France (Thyer, 645). Nepal is a small country, land-locked between India and the Tibet region of China in South America. It is 900 kilometers from east to west, and 150 to 250 kilometers from north to south (Spence, 223). Nepal is home to eight of the ten highest mountain peaks in the world, most notably Mount Everest, which lies at 8,848 meters. In contrast, some of the areas that are situated lower in Nepal are only about eighty meters above sea level. Clearly, Nepal has much climate variation; in fact, the climate progresses from tropical to arctic within a 200-kilometer area from south to north (Agrawala, 12). There are five geographical regions in Nepal (though, sometimes the mountain regions are grouped together as one). The Terai plain is the southernmost strip, bordered to the north by the Himala... ...
