Maintaing A Work Family Balance Social Work Essay

Maintaing A Work Family Balance Social Work Essay Achieving a balance between work and family is important to everyone. A balance between work and family responsibilities occurs when a persons need to meet family commitments is accepted and respected in the workplace. Helping people achieve a balance between their family needs and their work commitments supports productive workers as well as committed family people. Provisions to assist with the balance between work and family must be available to everyone in the workplace. However, not all people in the workplace will need to or wish to access these provisions. These provisions reduce the barriers that may prevent people from entering and remaining in the workforce. They enable people with caring and family responsibilities to have equitable opportunities to progress in their career in the same way as those without these responsibilities. Work and family balance provisions contribute to equality in the workplace by recognising that some workers have caring responsibilities. They enable those workers to have fair access to workplace opportunities. Work-family facilitation, or the extent to which individuals participation in one life domain (e.g., work) is made easier by the skills, experiences, and opportunities gained by their participating in another. Frone (2003) suggested that work-family balance likely represents multiple dimensions composed of bidirectional (i.e., work-to ­family and family-to-work) conflict and facilitation. Finally, Hammer (2003) called for an explicit expan ­sion of the work-family paradigm to include work- family facilitation. Unfortunately, work-family facil ­itation remains conceptually and empirically underdeveloped (Frone, 2003), and its distinction from conflict remains unclear. Background Work-family conflict is a form of interrole conflict in which role pres ­sures from the work and family domains are mutually incompatible in some respect (Greenhaus Beutell, 1985, p. 77). The conflict does not operate in one direction. Family sometimes interferes with work (FIW), and work can interfere with family (WIF). Further, some researchers suggest that conflicts between the work and family domains can occur when (a) time consumed by one role results in a lack of time for the other, (b) strain caused by the activities of one role makes it difficult to fulfill responsibilities in the other, or (c) in-role behavior in one domain is incompatible with the role behavior in the other domain. The time conflict is fairly obvious and probably most salient to us lay people (i.e., non ­work family conflict experts). So is strain-if were totally stressed-out at work, we may not be able to deal with our family responsibilities and vice versa. However, the behavior component is less obvious. It has been sug ­gested that we may sometimes behave in ways in one domain that is incom ­patible with the other domain, such that the behavior in question does not facilitate fulfilling ones roles in the other domain. For instance, being a per ­fectionist may be useful at work, but the same behaviors may lead to less effective parenting or in other ways inhibit one from adequately fulfilling family responsibilities. It should be noted that the conceptual grounding of time, strain, and behavior-based dimensions of work-family conflict have been debated. As Mike notes, they do not have strong empirical validation and may confound the work-family construct with its putative causes and outcomes. What happens if work-family conflicts are not effectively managed? Work-family conflict can result in a number of dysfunctional outcomes, including burnout, decrease in mental well-being, deteriorating relationships, and job and life dissatisfaction. Presumably in the hopes that a better under ­standing of the causes of work-family conflict will help people avoid it, con ­siderable research has been directed toward trying to understand the antecedents of work-family conflict. Some of the things that lead to conflict are fairly intuitive. For example, working long hours, long commutes to and from work, workload, lack of management support, job involvement, and level of importance assigned to ones work, all predict the extent to which WIF. Further, marital status, number of children, level of importance assigned to family roles, and lack of family support all contribute to FIW. Further, some people are more susceptible to work-family conflict than others. For instance, research suggests certain personality types are more inclined to experience work-family conflict. Neuroticism, Type A tenden ­cies, and negative affectivity are all related to work-family conflict. As one might expect, age also relates to work-family conflict. Theres initial evi ­dence that as we get older, we develop more effective strategies for dealing with these conflicts. Objective:-Both academic and corporate research are confirming the existence of work-to-family and family-to-work spillover and the importance of healthy work-family interface for families and businesses. This is to prove that there is a need of balancing work family in everybodys life irrespective of the work he/she is doing to maintain a healthy time table for the commencement of day to day activities.Our day to day schedule is becoming hectic.In such situation peoples are losing their temper, are into wrong doings of all sort.Schedule needs to made for maintaining a healthy Work-Family Balance.People are so busy in making money that they started neglecting their family.They start giving more importance to their work and no time for family.This should not be the case as all these make a man a mechanized robot.They began neglecting all social activities,as a result their family suffers or feel their absence and sadness fill their lives. Unhappiness creeps in such family and destr oys their life.We should keep in mind that Money is not everything in Life.Yes,we can say money as the need fulfiller.we can fullfill are needs with the money earned.But we should not be always money making oriented.If we neglect our family for making more money, then all money earned goes worthless ! So,apart from work giving quality time to the family is very essential. Work-Family Balance Work- family balance is a term that refers to an individuals perceptions of the degree to which s/he is experiencing positive relationships between work and family roles, where the relationships are viewed as compatible and at equilibrium with each other. Like a fulcrum measuring the daily shifting weights of time and energy allocation between work and family life, the term, work-family balance, provides a metaphor to countervail the historical notion that work and family relationships can often be competing, at odds, and conflicting. Sociologist Rosabeth Moss Kanter was one of the first scholars to critique the prevailing assumption that workplaces and jobs must be designed to separate work from family demands. She challenged this approach as being socially necessary for employee effectiveness in carrying out the dual demands of being a worker and being a family member. She noted that as employing organizations shifted to be more demographically diverse, these stereotyped views on appropriate work and family relationships needed to be re-viewed in order to prevent negative processes affecting individuals and groups who were demographically different from the majority. Women as a growing minority group in employing organizations were having difficulty rising up the hierarchy and being accepted as managers as they juggled employment, and caregiving and domestic demands. These same issues are still relevant to organizational studies today. Most men and women are juggling competing life demands outside of workplaces that still are largely designed based on a culture that work is the central role in employees lives, and a belief that workers should sacrifice family personal roles in order to be successful on the job. From Work-Family Conflict To Work-Family Enrichment: Competing Negative and Positive Views Traditionally, researchers have assumed a win-lose relationship between work and family and focused on work-family conflict, based on the belief that individuals have limited time and resources to allocate to their many life roles. Most research relevant to the notion of work-family balance has been conducted on work-family conflict, which can be viewed as the opposite of work-family balance. The construct work-family balance is a more positive way of viewing work-family relationships. It is consistent with the emergence of a new stream of research being promulgated by such writers as Greenhaus and Powell on work-family enrichment, the idea that work and family can also enrich and complement each other. Overall, research on work-family balance can be characterized as being organized along these competing positive and negative perspectives. Work-Family Conflict The negative perspective on balancing work-family relationships emanates out of role conflict theory, which Goode noted assumed that having multiple roles is distracting, depletes resources, and results in role strain and overload. With regard to work family roles, when employees try to carry these competing demands out while being embedded in traditional workplaces that are designed to support separation of work and family demands, they are likely to experience higher work-family role conflict. Greenhaus and Beutell wrote one of the earliest theoretical articles on work-family conflict. They defined work-family conflict as a type of inter-role conflict where work and family roles are incompatible and seen as competing for an individuals time, energy, and behaviours on and off the job. Their work built on earlier role theory by Ebaugh and others who defined a role as involving behavioural expectations associated with a position in a social structure. Early research on work and family didnt necessarily differentiate where the role conflict was occurring, such as whether it was due to an inflexible job (work to family conflict) or whether it was due to not having back up child care for when a child was sick (family to work conflict) Later Kossek and Ozeki conducted a meta-analysis reviewing decades of studies that show that life and job satisfaction for men and women is affected by the type and direction of these competing role dynamics. Given womens traditional greater responsibility for caregiving, work to family conflict was found to affect life satisfaction to a greater degree for women than for men. Job satisfaction for men and women was equally affected by family to work conflict. Understanding the type, direction, and source of the conflict can help organizations and managers design appropriate workplace interventions to support work-family balance. For example, having to work overtime on a job and being forced to miss a childs school event is an example of time-based work-to-family conflict. However, being absent from work because a babysitter did not show up is an example of time-based family- to- work conflict. For the overtime example, an organization might allow for just in time worker scheduling to allow those workers with the most interest in overtime to volunteer. In the other example, managing overtime wouldnt solve the babysitter not showing up. Helping the employee find back-up care for emergencies or letting them work from home once in a while in emergencies would. An example of energy-based family-to-work conflict is when an employee is too tired to work well in the morning because he or she was up all night with an ill spouse. An example of energy- based work to family conflict is when someone is too tired to cook dinner or clean the house, because of working too intensely on the job. In order to promote work- family balance to promote better energy allocation between roles, in the first example, the firm needs to provide dependent care support or leave from work. In the second example, the firm might need to increase staffing levels so the workload is dispersed among more workers, or provide stress management techniques that allow workers to take breaks. An example of behaviour-based family-to-work conflict is when one is so stressed from a family demand, that the individual is unable to concentrate at work or exhibits private emotions such as crying at work that would be more associated with the private sphere. An example of behaviour- based work- to-family conflict is when someone comes home and yells at ones spouse or kicks ones pet because of anger related to work. In these cases, interventions to reduce the stress in the particular domain where it is occurring would result in better work-family balance. Work-family enrichment. The positive approach to studying work-family balance emanates from Seibers role accumulation theory which assumes that having multiple life roles can be psychologically enriching, as long as the roles are ones that the individual has high identity with, sees of good quality, and reap rewards and life privileges. Under a role accumulation perspective, a person can achieve balance by being able to regulate and have greater control over when where and how invest time and energy between work and family to ensure that they perceive they are accumulating positive outcomes from both roles. The more roles one has that provide positive rewards, the better off an individual is, unless s/he has too much too do from the sum of these roles (causing role overload) or has too many competing role demands. The assumption is that work and family balance have instrumental and affective paths. The instrumental path focuses on how positive skills and behaviours and rewards from one domain (such as incom e, learning how to manage people or solve problems) can help one perform better in the other domain. The affective path focused on the degree to which mood and emotions from one domain can seep in and positively impact how one feels, acts and behaves in the other domain. So if someone has a good day at work, s/he comes home and are able to have extra energy and emotions to allocate to the family. Or if one has a wonderful family life, s/he is able to bring these positive emotions to work. A final set of studies focus on the processes of balancing relationships between work and family. Some writers focus on compensation- how having a better role quality and higher identity in one domain such as the work role may compensate for lower role quality and investment in another domain such as family. For example, an individual who highly identifies with work might invest more in work roles to compensate for a less fulfilling family life. Other writers might focus on segmentation and integration processes, the degree to which individuals have preferences for keeping work and personal roles segmented or integrated. Job and organizational design can interact with preferences for the enactment of life roles and management of the work and family boundary. A study by Kossek, Lautsch, Eaton on teleworking found that individuals who teleworked and adopted an integrative boundary management style were likely to experience higher work to family conflict but not family to work conflict than individuals who adopted a separation style. Their study showed that the more the workplace is brought into the home via job and organizational design, the more likely it increases work-to- family conflict, particularly for individuals who like to integrate work and family roles (say watching children while taking a work call). Cross-over effects is another new area of study: how the work-family balance of one family member such as a wife or husband may transfer over positive and negative relationships to the other spouse. For example, if a spouse has a good or bad day at work the balance of the partner may be affected. Direction Of Work- Family Interactions, Disciplinary Foci, and Levels of Analysis It is also important to note that research on work-family balance is grounded in distinct disciplines that are not well integrated, which influences the direction and content of studies focus. Besides generally designing research studies as measuring generally positive or negative outcomes from balancing work and family, writers in the field have tended to focus on either how work affects family OR how family affects work. This tendency to assume a particular direction of relationship has ramifications for the measures and outcomes studies. In several handbooks such as Work and Life Integration and The Work and Family Handbook, the editors noted that researchers who study how family demands are affected by work demands often use different measures and focus on different levels of analysis in assessing work-family relationships then management scholars who might study how work responsibilities are affected by being a parent or a spouse. One large cluster of studies focuses on how family demands affect work. Historically, much of the writing in the management and organizational literature followed this approach. A general assumption is that the more family and other nonwork demands and interests an individual has, the more likely work is going to be negative impacted. For example, researchers in this stream might measure the number of children an employee has, his or her marital status. They would then link these personal demographics to the degree to which a person experiences positive work attitudes (e.g., commitment, job satisfaction) and work behaviors (e.g., turnover, performance). The level of analysis tended to be largely individual and focused on the employees personal, family and work characteristics. The other directional group of studies examines the different ways work impacts the family. Writers coming from this approach tend to emanate out of psychology and sociology and belief that the structure, stresses, and demands of work can make it more difficult for individuals to fulfill their family responsibilities as well as experiencing job stress at home. Some people refer to this negative seepage as negative spillover from work to home. Writers from this perspective might measure the degree to which inflexible work hours, lack of supervisor support, job demands and the structure of the workplace, negatively impact family and personal outcomes (e.g., job satisfaction, equal participation in family and domestic roles, life satisfaction, work-life balance). Here the level of analysis tended to focus more on workplace, job and organizational level. Researchers also might typically study of the availability of policies to support work and family, and the degree to which organizational culture and managers provided a supportive culture and norms to facilitate use of policies as well as positive relationships between work and home. For example, an individual would not have to sacrifice their family life in order to get ahead at work. Moving From Study of Work and Family To Study of Work and Life Integration The future directions of the work and family field are moving from the notion of work and family balance and conflict to terms of growing acceptance of work and nonwork life balance or work and life balance. Such terms suggest that many employees, even those without dependents or visible forms of family related to caregiving can experience the need to seek work and family balance. It also suggests as men become more involved in caregiving and domestic roles and women more involved in work and breadwinning roles, conflict and enrichment may more strongly relate to the role an individual is enacting (e.g., caregiver or breadwinner) than gender. METHODOLOGY Managing Work and Family Surprisingly, our literature has more to say about the antecedents and con ­sequences of work-family conflict and less on strategies to effectively man ­age it. However, there are some studies that have explored this issue and just knowing what causes work-family conflict can lead to an understanding of how to effectively manage conflict. Carefully consider work-family issues when choosing a job. The prede ­cessors of this column once interviewed Kevin Murphy and asked him how he manages work-family conflict. One thing he did was to choose a job that would offer him flexibility to deal with his family life. For example, if a potential employer seemed less than favorable about bringing children to meetings, that wasnt a job he wanted. Admittedly, not all of us have so many options to choose from that we can afford to be this selective, but its cer ­tainly worth considering the type of environment that would be ideal and aiming for such positions. Be sure to find out how the organization youre considering feels about bringing kids into work or if there is a strict culture of coming in early and working late. If the organization frowns upon anyone leaving before 5:00 and you have kids that need to picked up from school, thats got to factor into your job decision or you could be facing years of con ­flict. Some firm s are family friendly while others have a reputation of not being so family friendly. Further, dont feel guilty or feel like you are settling by considering these issues. As Lillian points out, finding a job that allows you to meet your fam ­ilys needs is an issue of fit. We consider a host of fit issues when we make a job choice; why shouldnt we also consider how the decision is going to fit other aspects of our life? In other words, its important to take a holistic approach when youre searching for a job. Dont just jump on the most pres ­tigious offer or the one that offers the most money. Work-family issues must also be considered. Selection, Optimization, and Compensation (SOC). SOC is a life-man ­agement coping style for work-family situations. Although related, SOC is different from time management. This coping style consists of being more selective in focusing on a few goals, persistence in order to achieve those goals, and seeking additional resources (e.g., child care) to compensate for lack of time. Basically, it is suggested that those experiencing work-family conflict should take the time to evaluate which goals are most important to them and focus on achieving those goals. Take the time to evaluate your goals and if the activities you engage in on a daily basis help you to meet those goals. Does reviewing a textbook help you meet your goals, or is it a task that takes considerable time but does not help you make progress toward one of your goals? If a task does not help you make progress toward a goal and you have the ability to avoid it (i.e., its not a requirement of your job), dont hesitate to sa y no. Further, its important to recognize that you dont need to go it alone. You should find ways to compensate for lack of time. This may involve child care, paying to have your house cleaned, having groceries delivered to your home, or getting someone to walk your dog. Lillian points out that it may be easier for folks with money to compensate for lack of time because they can pay to outsource many of these things. Research shows that application of SOC in both the work and family domains leads to lower job and family stressors which lowers work-family conflict (in both directions). For a more detailed account of this strategy see Baltes and Heydens-Gahir (2003). Communicate your responsibilities to those at work and at home. As Lou points out, a very important part of managing work-family conflict is simply making those around you aware of your responsibilities. For instance, if you only have daycare certain times of the week and need to watch the kids when theyre not in daycare, tell your employer this schedule so you can be sure your home responsibilities are considered when meetings are arranged. You should have similar discussions with your significant other as well. There may be days he or she will need to make dinner or pick the kids up from school. Its also a good idea to talk often. Responsibilities at both work and home may change so its important to inform everyone when that occurs. Also, you may find some things are not working out and you need to devise a new strategy to accommodate all of your responsibilities. Time management. To minimize work-family conflict, its important to manage your time well. Im probably not telling you anything you dont already know, but let me add to this. Macan, Shahani, Dipboye, and Phillips (1990) suggest that time management can be broken down into three dimen ­sions. First, goal setting and prioritization involve daily decisions about what is most important to be accomplished. Second, the mechanics of time man ­agement include such activities as making to do lists. Finally, a preference for organization involves maintaining a methodical, organized approach to work. Just like the SOC model, the time-management model first stresses the importance of deciding on what goals are most important for you to achieve and making sure you focus on those goals Increase your social network. I know some of you are balking at this sug ­gestion. After all, if youre struggling to make time for work and family, how on earth are you going to fit a social life into the equation? Who has time for friends? Well, believe it or not, theres evidence that increased social support can help decrease work-family conflict. Further, Leslies own research sug ­gests that decreasing social involvement in nonwork activities actually leads to higher levels of work-family conflict (Neal Hammer, forthcoming). So, dont quit spending time with friends because you feel like you have too much to do at home and at work. Doing so could make you less effective in both domains. Future Research Trends Research on work-family balance is only likely to increase among organizational scholars. One reason for heightened interest around the globe in work-family balance today is changing workforce demographics. A general trend around the world is a gradual but constant growth in the labor market participation of women. Using the U.S. as an example, which has some of the highest rates, research by the Families and Work Institute shows that 83% of all two-parent families with children under 18 have both parents working at least part of this time. Another study by Cohen reports that half of all children under 18 will live in a single parent home for at least part of their childhood in the U.S. Besides individuals with children, work-family balance concerns affect employees in general. For example, research by the Families and Work Institute reports that one third of employees say they have to choose between advancing in their jobs or devoting attention to their family or personal lives and one third will have managed elder care- care for a parent over the past year. Another reason for growing interest relates technological transformations that have resulted in some workplaces operating 24-7 as well as the ability to telework and be constantly accessible to work and jobs by email and cell phone and pagers even when not formally at the workplace. With 24-7 operations, the definition of the typical workday and what work hours are normal to support work family balance are also likely to redefined. For example, a U.S. based view of a 9-5 Eastern time zone of normal working hours, may not provide balance for workers where it is the middle of the night in India or China. Future research on work family balance will focus on differences in cross-cultural perceptions, how needs for balance shift over the life course, and how different jobs, family structures, and demographic groups may vary in their access to, perceptions of and outcomes from the level of work family balance they are afforded on and off the job. Multi-level research integrating individual and organizational perspectives and measures, and positive and negative measures is also likely to increase in future studies. Job design and work and family rewards and resources are likely to become of particularly increasingly importance in studying work family balance and conflict with highest stresses at either end of the economic spectrum. Individuals in higher paid managerial jobs are likely to experience higher work conflict and a lower balance due to overwork. There will be too many work hours competing for individual time and energy and too high workloads. Individuals at the lower end of the economic spectrum will experience work and family conflict more likely due to a lack of flexibility and ability to control when one works and a lack of economic resources to buy high quality child care and dependent care. Thus, employees throughout the organizations hierarchy will experience lower work-family balance but for different reasons. This trend makes it critical for future research to not only measure conflict, but to assess the processes and reasons for conflict and the role of organizational and job structures, as well as family and social and cultural structures (such as how family responsibilities are shared or viewed as ought to be shared) in enhancing or mitigating conflict and balance. The more that workers have access to jobs enabling higher control how when and where they do their jobs and the amount of workload, and the more that communities are design to provider greater public and private supports to enable dual enactment in w ork and family roles, the more likely that members of society will have greater work-life balance.

Clouds Essay -- essays research papers

Cloud formations have always been observed by people, many centuries before our time. People were always fond of clouds. They always wondered why some clouds were dark and others were white and fluffy, and why some clouds are so up high and others were so low that they looked reachable by the human hands.   Ã‚  Ã‚  Ã‚  Ã‚  The most recent classification of clouds was accomplished by the World Meteorological Organization in 1956. This organization lists 10 basic kinds of clouds that are subdivided into species according to their outer shape and inner structure. In addition, cloud varieties are discussed according to arrangement and transparency. There is a height classification which are called high, middle, and low altitudes. The different kinds of clouds are found in these three divisions according to the clouds' altitude.   Ã‚  Ã‚  Ã‚  Ã‚  First, we have the high clouds that range in altitude from 16,500 to 45,000 feet. In this division we have the cirrus, cirrocumulus, and cirrostratus clouds. A cirrus cloud appears in delicate, feather-like bands that are not attached to each other, and is usually white with no shading. Cirrocumulus clouds appear like very small round balls or flakes. The cirrocumulus clouds sometimes form a pattern of a buttermilk sky. The cirrostratus clouds sometimes form tangled webs or thin whitish sheets. A large ring or halo is sometimes seen around the sun or moon when the cirrostratus covers the sky.   Ã‚  Ã‚  &...

Research Critique †Burns And Grove Essay

Introduction Burns and Grove (2011), define qualitative research is a standardized, personal way used to define life experiences and grant them meaning. A qualitative study must establish a dilemma or research problem, does not contain a hypotheses, and the research questions, which evolve as the study progresses are usually very broad. As a result, the person conducting the study looks for data to form impressions; this type of research cannot be measured. This qualitative research critique will analyze the problem statement, purpose and research questions, literature review and conceptual framework of Qualitative Study on the Impact of Falling in Frail Older Persons and Family Caregivers: Foundations for an Intervention to Prevent Falls. Critical Appraisal Problem Among adults 65 years of age and older, falls are the main purpose of injury death and the most typical reason for nonfatal injuries and trauma related hospital admissions. In 2010, approximately two million nonfatal fall injuries in older adults were cared for in emergency departments with costs totally approximately $30 billion (Centers for Disease Control and Prevention, 2012). Injuries sustained from falls include fractures (hip, spine, forearm, leg, ankle, pelvis, hand), lacerations, and head traumas. Often times after a fall, an individual will become disabled, lose their independence, or develop a fear of falling again causing them to decrease their activity level. Decreased activity level results in decreased mobility and muscle mass, loss of being physically fit, and actually increases an elderly person’s chances of falling. In addition to the physical injuries from falls, patients also suffer emotionally and socially, as do their caregivers from increased dependence on them. Purpose and Research Questions The objective of the study was to review the impacts of falls in older adults, some of whom had cognitive impairments and the impacts on their  primary caregivers who were family members. The subjects taking part in the study all had recently experienced a fall. The other purpose of the study was to make recommendations for a fall prevention program. While the researchers did not provide the questions they used, based on the information given they were questions such as: What are the consequences you fear from falling (physical, emotional, social)? What caused the fall? How did you cope with the fall? What do you expect from a fall prevention program? The qualitative method of the grounded theory: a constant comparative analysis to identify common themes and issues was used to answer the authors’ research questions. Qualitative research is a methodical, personal way used to illustrate personal experiences and give them meaning. In a qualitative study, participants are chosen by those conducting the study to participate because of their knowledge, views, or experiences related to the study rather than by chance (Burns & Grove, 2011). In this study, the purpose and research questions used were related to the study about falls in the elderly and the impact it has on both them and their caregivers. Literature Review The authors of the article researched both qualitative and quantitative studies relevant to the focus of their study on falls. The study used references from 1988 through 2009 and approximately half of them were greater than five years old and the other half were less than five years old. Protocols for qualitative research were followed with regard to purposive sampling and triangulation, the sampling and data analysis reached saturation, and the manuscripts of the interviews were tested with interviewees (Faes et al., 2010). Some weaknesses of the study were the small sample size and the fact that the results were not statistically valid for other populations. The literature review presented valid evidence and information to support the authors’ argument for the need for a fall prevention program to discuss and educate people on ways to reduce the consequences of falling and provide information on safety to prevent falls. Frame of Reference When conducting this study, the grounded theory guided the authors who interviewed 10 caregivers and 10 patients. Three patients were cognitively unimpaired, four had mild cognitive impairments and the remaining three were dementia patients. All patients had experienced a recent fall and both them and their caregivers were used as the authors’ frame of reference. After the study, a framework was developed from the study findings that consisted of two tables that presented the socio-demographic and health characteristics of patients and the socio-demographic and health characteristics of caregivers and their care recipients. Interview responses were also categorized into the following categories: emotions, social consequences, attributions, coping, burden and rewards of care giving, and fall prevention program. This framework was used by the authors to determine the need for a fall prevention program. Conclusion Falls impact the elderly physically, emotionally and socially as well as contribute to added stress amongst their caregivers. Therefore, the authors of this study suggested that a fall prevention program involving both patients and caregivers should be implemented. The fall prevention program should target reducing the consequences of falling, provide advice on walking and standing more safely, promote self-efficacy and activity, and discuss the cause of falls (Faes et al., 2010). Caregivers should also be properly educated on ways to prevent falls and on how to supervise cognitively impaired patients. References Burns, N. & Grove, S.K. (2011).

America Outsourcing

Outsourcing has been a subject of debate in the world's developed countries with questions on whether it should be regulated. This follows the effect that outsourcing has had on the economies of host countries. Top in the agenda is the loss of jobs to outsourcing which has led to income inequality and joblessness in the host countries.The benefits of outsourcing however remain significant in these economies earning large amounts of revenue. To illustrate this facts, the case of General Electric will be used to analyze the role that outsourcing has played in the U. S economy.Impact of outsourcing on GE and their decision to have multiple outsourcing partnerships.General Electric (GE) has placed strong emphasis on expanding their business to international markets through outsourcing which has not only provided the company with huge revenues but also given it a strong command as the biggest company in the world by market specialization in 2004.Its international presence which has proved to be very powerful has given GE a competitive edge over other companies in the U.S which have not outsourced as expansively as it has. GE has benefited from the advantage of cheap human capital available to it in Asia, Mexico, India, China and other countries in which it ventured into.GE which specializes mainly in financial services, medical equipments, jet engines, plastic manufacture among others cannot at one time regret the decision to outsource to these countries as a result of the gains they have obtained. In India for example, the GE benefited from the large group of educated English speaking locals who provided inexpensive labor for the company.It is estimated that with two to four years experience a computer programmer in the US earned $62,000 while the same person earned $10,000 only in India.These reduced costs have fostered savings for the company giving it room to expand its activities even more. GE now boasts of its presence in over one hundred countries. Of the tot al revenue that GE earned in 2003, 45% came from the international markets which goes on to show that outsourcing has had a positive impact on the company.The company apart from benefiting in cheap labor imported materials from its home country, processed it in the subsidiaries and then sent it back to the country. The effect of this is that the production costs were reduced and the products were sold t the same price. The foreign countries also provided market for the products as well as supply of cheap and available materials.The decision for GE to have multiple outsourcing partnerships can mostly be attributed to the gains in cost cutting it was bound to benefit from such kind of arrangements. Consider that GE earns 45% of its revenue from foreign subsidiaries. This is the major reason for GE to continue outsourcing to maintain a significant flow in its revenues.As stated earlier, GE stands to obtain numerous advantages from investing in the foreign countries through outsourcing. It comes in as the nature of business to take advantage of available resources and making the maximum use of them to obtain maximum benefits.GE through outsourcing has established international partnership and it stands to gain a lot in terms of profits and reduction of costs. In the case of Mexico, the government provided for duty free import of raw materials, testing equipment, telecommunication equipments, tools and machinery. This was aimed at increasing foreign direct investment of the country which would in turn benefit from the improvement in infrastructure ad an increased job market for its citizens Warden, S. (2002: 124-133).GE was hardly affected by the income tax law which also provided for refunds on money used to export products by GE from Mexico to U.S (Vietor, 2007: 4). As a result of the huge savings made, the company advanced at a high rate establishing many plants in Mexico producing electronic motors, capacitors and lighting devices.

Entertainment And Education Essays - Occitan Literature, Poets

Entertainment And Education Essays - Occitan Literature, Poets Entertainment and Education Both entertainment and education have been integrals parts of the human experience since the beginnings of time. Many scholars insist that the two institutions often serve jointly, with entertainers and entertainment serving as a main source of education. There is little argument, then, that in addition to generally appealing to the masses, entertainers have regularly fulfilled the role of a teacher to typically unsuspecting audiences. Entertainers have served as educators throughout history, from the origins of oral narratives through the Middle Ages. The earliest forms of unwritten communication were essentially used to spread knowledge from one source to another. Religious disciplines were the first information passed from person to person through entertainment. In the third century B.C., Buddhist monks tried to win converts outside India through the use of theater and song (Burdick 97). They taught the precepts of Siddhartha and Buddha in such theatrical epics as Ramayana and Mahabharata, setting exacting rules for theater performance in the process (Burdick 99). Similarly, Irish monks established singing schools, which taught uniform use of music throughout the church (Young 31). Through chants which were all the same, they spread identical teachings. Christian psalms and hymns in Apostolic times were sung to spread the knowledge and faith of Christianity. In fact, Christianity was promoted from the start by music. Churches were for long the only centers of learning, with monks teaching all lessons through music (Young 39). Through the use of sacred music, monks and clergy successfully spread the teachings of their religions in a practical manner. Entertainers used the theater as a place to tell the stories of the day, both fictional and topical. The African oral tradition was rich in folk tales, myths, riddles, and proverbs, serving a religious, social, and economic function (Lindfors 1). Likewise, Asian actors covered their faces with masks in order to act out a scandal of the day without the audience knowing who was passing along the gossip (Archer 76). European puppets were another medium which permitted entertainers to spread current gossip without revealing the identity of the storyteller (Speaight 16). The theatrical productions of the Greeks further explored the use of theater as an instructional tool. Because the theater provided such a diverse forum for expression, stage actors and playwrights consistantly utilized this locale to eduate the general public. Oral communication was widely used to educate society about morals and basic truths. The most highly developed theoretical discussions from ancient times were those of he Greeks, who passed on this knowledge through music and stories. Homer, the eighth-century B.C. poet, court singer, and storyteller, embodied ideal Greek morals and heroic conduct in his spoken epic, The Iliad (Beye 1). Homer and other poets used qualities not found in written language to make the memorization of their works easier so their sagas could be repeated for generations (Edwards 1). African tribes people and Native Americans also instilled morals and lessons to their communities through stories and fables (Edwards 1). These oral narratives were soon after recorded on paper as early forms of literature became prevalent. Many of the thoughts previously expressed through oral communication only could now be recorded for the future as writing became wide-spread. The era of writing began with Chinese literature more than 3,500 years ago, as the Chinese recorded tales on oracle bones (Mair 1). The Greeks, however, were the first known civilization to translate their oral history into writing (Henderson 1). While the earliest Greek literature was produced by the Indo-Europeans in 2,000 B.C., the most essential works began in Ionia with the epics of Homer in the eighth century B.C. (Henderson 7). This oral poetry is the foundation of Greek literature, and epic poetry such as Boetian?s Hesiod explored the poet?s role as a social and religious teacher (Henderson 8). These written works clearly informed those who read them, but were not as successful in educating the masses as the Greek dramas. Any spoken works that were especially significant could now be transcribed for posterity and future use. Greek plays were also recorded on paper beginning around 500 B.C., reflecting issues of the day and entertaining audiences concurrently. The tragedies of Euripides reflect political, social, and intellectual crisis. Plays such as The Bacchae reflect the dissolution of common values of the time, while other works criticized traditional religion or represented mythical figures as unheroic (Segal 1). Each Greek drama was similarly structured: problems were ?presented by the chorus, and resolved in purely conventionalbut always instructiveways? (Burdick 18). Topical comedies reflected the heroic spirit, and problems facing Greek society during times of great change (Henderson 2). Meanwhile, the dramas of Socrates spoke

The Possibility of Time Travel Essay Example

The Possibility of Time Travel Essay Example The Possibility of Time Travel Essay The Possibility of Time Travel Essay Essay Topic: The Time Machine The possibility of time travel Introduction Although the study of time travel is a fairly new topic of scientific and philosophical investigation, it is so well-known because of different literature, films and stories in our daily life. It is believe that most locals have got access to at least one such production related to time travel. Yet, the possibility of time travel is still a question mark to them. Is it possible to have a time travel? The answer is definitely yes. Although not every scientist agrees with the answer, supporters of relativity would also be supporters of time travel. Moreover, some scientists or philosophers give explanations to the paradoxes and make the answer almost certain. In this article, we give a clear explanation to some kinds of time travel with high possibility such as time travel to the future. For time travel to the past, we discuss the possibility and point out the impossibility of some counter arguments as well as the contradiction of some ‘paradoxes’. Definition Among lots of definitions of time travel, David Lewis’s version is easy for everyone to understand. An object time travels if and only if the difference between its departure and arrival times in the surrounding world does not equal the duration of the journey undergone by the object (1). Although the definition of the phrase ‘surrounding world’ is indefinite, we give such definition: the environment at sea level on the Earth. Yet, things are not clear. What is time? Philosophers offer a few explanations such as eternalism, possibilism, and presentism(2). Eternalism and possibilism give same explanation for the past and present The eternalist thinks that time, correctly understood, is a fourth dimension essentially constitutive of reality together with space. All times, past, present and future, are actual times just like all points distributed in space are actual points in space, while possibilism suggests that future is the only possible. They are in fact the determinism and indeterminism version of the similar theories. The presentist thinks that only temporally present objects are real. Whatever is, exists now. The past was, but exists no longer; the future will be, but does not exist yet. ’(3) Therefore, the past does not exist and we cannot travel to the past. We would put presentist aside and consider eternalism (or possibly possibilism). The above gives the concept of time-flow. Yet, the time-flow of a person might not be the same with the others. Time could distinguish from physical time or external time (which we defi ne as the time at the surrounding world) and personal time or inner time. Put this into the definition of time travel, we could get the combination: An object time travels if and only if the inner time during the journey is different from the external time(4). To be more detail, if the inner time is longer than the external time, we call it ‘time travel to the past’, while we called it ‘time travel to the future’ for the opposite. Relativity and time travel It is important to understand general relativity before studying this issue. In Newtonian gravity, which we usually learn in high school, the source of gravity is mass(5). In special relativity, we replace the term mass with more accurate terms, including energy, momentum densities, pressure and shear, called energy-momentum tensor(6). Using the equivalence principle, this tensor could curve space-time since time and distance are not the invariance but the speed of light is. This breaks many people’s common sense. The distance and time are not fixed but variable when under different gravitational force or experiencing different ‘speed’. The theory shows that if the gravitational force and the speed change, the inner time could also change and the way of time travel is to change the force and the speed(7). This is explained in later chapter. Real case of relativity in daily life Do you believe that we could have time travel by a bus? It is possible. Assuming the bus is moving at 70km/h and by definition the speed of light is constant, the inertial frame of the bus passenger is moving relative to a standing pedestrian acting as a stationary inertia frame. Put it in this way. The lights observed by the pedestrian on the road and from the bus are all at speed c. The lights observed by the passenger from the bus are also at speed c. Yet, we must not forget the fact that the passenger is at 70km/h going at the same way of the light from the bus. By common sense, the passenger should observe the light going at speed (c-70km/h) but he does not. Who takes this 70km/h away? In fact, no one take it. That’s because the passenger is experiencing a time travel, which is called ‘time dilation’ by Einstein (8). That the time on the bus is a bit slower than the time of a person in stationary inertia makes two people see the same speed of light. After a trip from Lingnan University to my home, I should be a few picoseconds (1nanosecond=1000picoseconds) younger than I should have. Moreover, such daily usage of time differences happen everyday. For example, the clock on GPS satellites is affected by both different speed and gravitational force relative to the clock at sea level in stationary state. By special relativity, it experiences a future time travel of 7. 2 microseconds per day according to its high rotational speed. By general relativity, it experiences a past time travel of 45. 9microseconds per day according to its ‘lost’ of gravitational force because of its high altitude. Therefore, the clock of the satellites should be 38. microseconds slower than a normal clock per day(9). ‘Real’ time travel to the future Although the above cases are real cases in most senses, people would argue that it’s not the ‘real’ time travel as they cannot observe the case obviously. ‘Can I jump into a machine for a while and the external time goes fast forward for several years? ’ This is people’s imaginatio n. Since we have the empirical prove from the GPS satellites, the problem is not the possibility but the degree of the travel. In my, as an art student’s, erspective, the easiest way would be using an extraordinarily extremely fast space shuttle to move toward a remote planet with an extraordinarily extremely strong gravitational force, rotate around it and move back to the Earth. After a yearly trip, he would probably saw his granddaughter breathing her last after aging. ‘Real’ time travel to the past This is a bit harder for we human being. Same as above, the question ‘can I jump into a machine for a while and the external time goes fast backward for several years’ could be asked. It is suggested that we could do it in some ways, which all of them are only hypothetically applicable. First, we could use a moving machine which could move faster than light. According to special relativity, if an object or information could move from one point to another faster than light, it could have moved backward in time(10). Second, we could use wormholes(11). The theories behide are out of a philosophy student’s handle. Yet, it is proved by Einstein field equations of general relativity and openly discussed by some professionals such as Stephen Hawking. The limitation is that we could only go back to the day the time machine built(12). Time travel and Philosophy While the possibility of time travel is proven by physical theories, what is related to philosophy? Although scientists have spotted out the physics theories behind, something is still unable to explain by science. For example, presentism (which we put aside before and probably after this sentence) suggest that we could not travel to a destination which does not exist. Moreover, if I can prove myself exist, who can prove the existence of the future me standing in front of me? At the same time, the physics affects some definition of philosophical theories. According to possibilism, our past and present are actual times but our future is the only possible. Says that 07:00 of 07/07/2007 an object was disturbed at a particular position, would a time travel to past before 07:00 of 07/07/2007, says 06:00 of 06/06/2006 of one make the time 07:00 of 07/07/2007 become possible from actual for him? In another word, change the history? Even if determinism exists, if an object is determined to go back to some time before, would it replace or affect the before it? Since questions arose in many senses, paradoxes appeared. The grandfather paradox(13) and similar The paradox is this: suppose a man travelled back in time and killed his biological grandfather before the latter met the travelers grandmother. As a result, one of the travelers parents (and by extension the traveller himself) would never have been conceived. This would imply that he could not have travelled back in time after all, which means the grandfather would still be alive, and the traveller would have been conceived allowing him to travel back in time and kill his grandfather. Thus each possibility seems to imply its own negation. Similar paradoxes came out like bamboo shoots after a spring rain. The simplest one is that one goes back to the past and kill the past him. Will he exist anymore? Philosopher Bradley Dowden even makes his argument with these paradoxes(14). He wrote that: â€Å"Nobody has ever built a time machine that could take a person back to an earlier time. Nobody should be seriously trying to build one, either, because a good argument exists for why the machine can never be built. The argument goes like this: suppose you did have a time machine right now, and you could step into it and travel back to some earlier time. Your actions in that time might then prevent your grandparents from ever having met one another. This would make you not born, and thus not step into the time machine. So, the claim that there could be a time machine is self-contradictory. † The solution of this paradox could simply ask a local kid as the cartoon ‘Doreamon’ is so popular among kids. â€Å"If you use the ‘If Telephone’ to change the world, the world could return to normal if and only if you use the telephone again in the same (parallel) world(15). † answered by a kid in the local playground. The parallel universe is a new topic to scientists but an old topic for fiction and animation. Let’s put it this way: Assume there is a person Tom. The present Tom is the real Tom in the present world, named world A. Since time is irreversible, Tom’s grandfather has met Tom’s grandmother and so on. It is an actual case happened in this world A. If you go back to a place where that particular case would still be a possible future, that particular world must not be world A but a parallel world, named world B. Even if Tom kill that ‘grandfather’ before he would have met his wife, Tom would only prevent the existence of Tom in that parallel world B but not the Tom in the original world A. Existence of parallel universe One may question: does parallel universe exist? No matter it exists or not, the grandfather paradox is still meaningless if we are clear-headed. Assume that it exists; it is obviously no more a paradox. If it does not exist, Tom could never go back to a time before he could be since by something past is actual and irreversible by definition. The past cannot be changed by definition since no parallel world could be changed by him. He will never succeed and therefore it is no more a paradox. The only ‘change’ (would it still called a change? could be done by a ‘future object’ must have been past and become an actual time just like everything is determined and becomes a history, while some people would still called it a paradox named Predestination paradox but it is something determinism could explain. Conclusion Although the paper does not mention some related theories, it included most physical and philosophical theories needed to cover this topic generally. In this topic, physicists and philosophers affect each other and new ideas spark every moment. The philosophical theories give idea to physicists and hysics theories change the mind of philosophers. In conclude, a time travel to the future is possible. Similar events occur everyday. A time travel to the past is partially possible. For those who is just travel relatively past to the external time but still future comparing with the time of depart, such time travel is possible. Similar events happen occur everyday. For those travel which the arriving destination is before the departure time, a parallel universe should be exist or the ‘past’ should already be determined. Otherwise, such travel may not exist.

Globalization and Its Effect on the World Essay

Globalization and Its Effect on the World - Essay Example It shows that the East Asia Pacific has grown from a GDP of 15.8 in 1980 to 36.3 in the year of 1997. This has also been seen in the region of Europe and Latin America. The lowered accessibility of finance in the 1980s resulted in suppressed growth which led to many problems. It was after this that the new funds designated to states included the aspect of foreign direct investment. This type of investment is encouraged in the developing countries because they can help in increasing the capital of a state through which the state can further develop economically. Globalization is an aspect which not only helps the countries directly but also helps the countries to improve indirectly. It helps in the improvisation of the living and working standards of a country. Foreign Direct Investment is a type of process through which globalization has given a direct advantage to the countries whereas an indirect advantage can be witnessed in the accessibility of these types of investments to diffe rent states. The concept of globalization has increased the interest of developed organizations to expand their business in countries where it was previously unknown. As the organizations are expanding it can be seen that their products are widely distributed all over the world. Moreover the distribution channel of the new product helps the countries to increase their understanding about the technological advancements of the world. Foreign investors not only help the country economically but they also help to introduce technologies which were previously not known in the country. The country can benefit from these technologies by using them in an effective manner such that their... Globalization and Its Effect on the World This essay analyses the factor of globalization, its impact on different aspects of the world and considers the question of the globalization real existence. Though it is still seen that some of the concepts relating to globalization have remained unexplored, a debate is going on between the proponents and opponents of globalization. Globalization has been defined by Goldstein as â€Å"the worldwide spread of industrial production and new technologies that are promoted by the unrestricted mobility of capital and unfettered freedom of trade†. This clearly shows that globalization affects the issue of investment and economy in this world. Furthermore, James Rosenau described the globalization as â€Å"a label that is presently in vogue to account for peoples, activities, norms, ideas, goods, services, and currencies that are decreasingly confined to a particular geographic space and its local and established practices". Globalization not only affects the microenvironment but also affects the macro environment from an economic perspective. Microenvironment here refers to the advancement in technology along with its effect on the organizations and macro environment is the whole situation in which the markets are operating. Therefore, the question here arises as to if globalization only has a significant effect on the economics. Studies have been carried out to find out the relationship of globalization and labor market trends and it has been analyzed that both of these have a relationship.

The Nurses Role in Prevention of Central Venous Line Infection Essay

The Nurses Role in Prevention of Central Venous Line Infection - Essay Example The problems identified for this research are that CVLI presents a serious health risk to patients, nurses are frequently in a position to contribute to the problem, and that training and prevention strategies should be employed to reduce the frequency and severity of CVLI. Significance of the Problem. The significance of CVLI cannot be overstated. It increases the morbidity and mortality rates of patients who suffer infection as a result of bacterial introduction and growth in what is often an immunosuppressed environment. This issue is important to nursing for two primary reasons; nurses are in a position to contribute to the frequency and severity of the problem, and they are also the first line of defense in prevention, detection, and resolution of CVLI. Research Hypothesis. The expectations for this research are that it will clearly demonstrate; that most cases of CVLI are preventable, the incidence of nurse contribution to the condition is high, a program of training and preventative strategies would reduce the frequency of infection, and that more research is needed to determine the protocols for a program of prevention. Literature Review. There are several studies on the subject of CVLI and the contributory issues involved. While this body of literature is informative, it does not obviate the need for the research proposed herein. From Hadaway, we know t... The expectations for this research are that it will clearly demonstrate; that most cases of CVLI are preventable, the incidence of nurse contribution to the condition is high, a program of training and preventative strategies would reduce the frequency of infection, and that more research is needed to determine the protocols for a program of prevention. CHAPTER TWO Literature Review. There are several studies on the subject of CVLI and the contributory issues involved. While this body of literature is informative, it does not obviate the need for the research proposed herein. From Hadaway, we know that central venous lines are much more likely to increase the frequency, as well as the seriousness, of infections than are short peripheral catheters. She points out that two factors that contribute to this fact are that the patients themselves tend to be more vulnerable, and the exposure to microorganisms is increased due to the more frequent access required in maintaining central venous lines (Hadaway, 2006, p. 58) These infections, particularly those at the site of the intravascular device, are a major source of morbidity, occur frequently, and have the ability to increase both the length of a patient's stay at the hospital as well as the costs associated with that period of convalescence (Musher, el al., 2002, p. 769). The research of Dr. Oudiz and his co-authors has found that early detection of infection in such patients is crucial, though it can be difficult given the fact that the symptoms often present in a generalized way and do not initially appear as an acute infection (Oudiz, et al., 2004, p. 92). When those symptoms do present, however, it is often necessary to remove the central venous line in order to eradicate the infection (Brooks &

Conceptual Framework - Essay Example This helps a myriad of users in making crucial economic decisions. Financial statements are needed to be prepared by keeping in view that the needs of the users of financial statements are fulfilled. They must contain all the information that is necessary for the general users’ financial information. However, some users require non-financial information about an entity which cannot be found in financial statements. The word ‘user’ mostly involves the current and prospective investors whose decisions are greatly influenced by financial statements. Financial statements show the ability of an entity to generate cash and cash equivalents in a timely manner. This helps in the determination of the fact whether an entity can pay its employees, other obligations and can settle its liabilities in time and still generate good profits. The information about the changes in the financial position of an entity helps in the evaluation of an entity’s performance over time and the current trend i.e. whether the profits are increasing or decreasing with the passage of time. Financial statements also present the financial structure of an entity which helps in understanding the future borrowing needs, solvency and liquidity. These are the critical pieces of information that an investor requires. Literature Review IASB requires that the financial statements must have four qualitative characteristics namely understandability, relevance, reliability and comparability. The attribute of relevance requires that the information provided in the financial statements must be relevant to the needs of the users. Irrelevant information cannot influence the decision making of a user. Paragraph 26 of framework says that the predictive and confirmatory roles of information are interrelated. For instance, information about asset holding enables a user to predict an entity’s ability to capitalize on the opportunities and to cope with adverse situations. For users w ho had made such predictions in a preceding period, the same information would play a confirmatory role as an entity’s structure and the outcome of previous predictions would be evident. Users use the financial statements to make a lot of predictions and they can make that foresight effectively if the relevant information is disclosed properly. For example, some items of income or expense are not conventionally seen in financial statements as they are unusual. Proper and separate disclosure must be made for such items so that their relevance becomes significant. For a piece of information to be reliable, it must be material. Information is material if its omission or misstatement could influence the economic decisions of users taken on the basis of financial statements. In statistical terms, information is regarded as material if it is more than 5% of the total profits. It depends on the size and nature of the item or adjudged error whether it is material or not. Materiality provides a threshold or cut-off point rather than being a primary qualitative characteristic which information must have if it is to be useful (Para 30). However, in some cases, the nature of information alone proves to be significant in the determination of its relevance. For example, when a new segment is reported, it affects the decisions of users as their assessment of risks and opportunities is affected. The future

The theme of Steinbeck's The Chrysanthemums Essay

The theme of Steinbeck's The Chrysanthemums - Essay Example Steinback explores the feminist approach in this short story. Summary of ‘The Chrysanthemums’ Steinback weaves a tale of a passionate woman, Elisa who lives in a male-dominated society. Elisa Allen lives with her husband in her ranch and is his helping hand. Elisa is shown as women more intelligent than her husband but being a woman, she cannot hope to become her husband’s equal. Elisa’s intelligence is matched with her passion towards the ranch, especially towards the Chrysanthemums that she plants. But even with all her intelligence and passion, she cannot guide her husband to improve upon the ranch. Her husband generally ignores her passions and treats her more like a sibling or a friend. Another man enters Elisa’s world, the tinker. The tinker is a person who has travelled much and matches Elisa’s intelligence. He woos her by complimenting on her Chrysanthemums and Elisa becomes attracted towards him. His attention towards Elisa, even thou gh is proved false in the end, makes Elisa aware of her own sexuality as she watches her naked reflection in the mirror after the tinker leaves (Steinback, 1995). However, Elisa is brought back to the realities of the male-dominated world when she finds that the tinker threw away the Chrysanthemums, she offered as a gift, after leaving the ranch. Theme of ‘The Chrysanthemums’ Gender Inequality is the main theme of the book and other themes are secondary to this theme and help support the actual theme. The book is set in the 1930s when males were given the ruling hand just because they were male. Females, on the other hand, were expected to be subservient and their use in the home was to help the husband. Steinback, uses this novel to point out the prevailing gender inequality at that time. Even though Elisa was more passionate about the ranch and had the aptitude to growing beautiful Chrysanthemums, she was not able to guide her husband towards any improvement in the ra nch. Even if she provided any suggestions, they were merely ignored by her husband. This was either because he did not expect her to come up with good suggestions or because he was not interested in making any changes. It is not just Elisa’s husband who gets to lead his life his own way but also the tinker who visits the ranch. The tinker lives an adventurous life, a life that Elisa envies because he gets to see the whole world and the beautiful flowers within while Elisa is only confined to the ranch. She cannot leave the ranch because females at that time were not allowed to leave her homes on such adventurous journeys without their husband. In the case of Elisa, her husband would not have been interested. Thus, Elisa is forced to live her life according to the wishes of her husband, while it is obvious there is so much more that she could with her life. Another theme in the short story is the sexual fulfillment of females. The society during that time was constructed on id eals that were not ideal for the females. Sexual fulfillment was only considered the right of the males while females were just necessary partners in the activity. It is clear that the relationship between Elisa and her husband is more fraternal instead of a husband wife relationship. The arrival of the tinker in the ranch awakens sexual feelings within Elisa and Steinback here makes a point that women are as likely to have sexual feelings as men; and that sexual feelings are so powerful that they make people behave in foolish ways. The passionate and robust nature of Elisa hints at a sexual person

Political Science Assignment Example | Topics and Well Written Essays - 250 words - 4

Political Science - Assignment Example The US foreign policy towards the Middle East was affected such that some of the countries involved in the Arab spring had their relation with the US tightened while others received the freezing of funds offered by the superpower (Ahmari, 2012). For instance, Libya received an arms embargo due to the continued fight by the Libyan air force against the protestants. On the other hand in the case of Egypt, the US praised the leaders for the transition from authoritarian to democratic government. According to Ahmari, the Arab spring brought about positive changes, thus building better relationships between the involved states and their neighbors. Ahmari defines the Arab Liberalism as the required change in the ruling system but is in crisis both culturally and morally. He views it as a threat to the freedom of future in Middle East (Ahmari, 2012). Ahmari feels that the Arab Liberalism is falling since it lacks an ideological plan like that present in Marshall Plan. I agree with Ahmari’s feeling that the Middle East requires a plan to follow in order to restore peace in the region. Lastly, it requires a role model in keeping up with democracy and maintaining peace with Israel as well as the whole of Western states. Arab Spring was meant to liberate citizens in the involved states from the oppressive leadership that dominated in the Middle East

Slack Bus And Slack Generator

Slack Bus And Slack Generator The Table below shows input data of each busbar in the system used to solve the power flow and the simulation result according to instruction described in question 1. BUS Input Data [Simulation Result] BUS 1 pu P (load) 100 MW Q (load) 0 Mvar BUS 2 P (load) 200 MW Q (load) 100 Mvar CB of Generation Open BUS 3 1 pu P (Gen) 200 MW P (load) 100 MW Q (load) 50 Mvar AVR On AGC Off Slack bus and slack generator In power flow calculation, unique numerical solution cannot be calculated without reference voltage magnitude and angle due to unequal number of unknown variables and independent equations. The slack bus is the reference bus where its voltage is considered to be fixed voltage magnitude and angle (1à ¢Ã‹â€ Ã‚  0 °), so that the various voltage angle difference among the buses can be calculated respect. In addition, the slack generator supplies as much real power and reactive power as needed for balancing the power flow considering power generation, load demand and losses in the system while keep the voltage constant as 1à ¢Ã‹â€ Ã‚  0 °. In real power system, when relatively weak system is linked to the larger system via a single bus, this bus can represent the large system with an equivalent generator keeping the voltage constant and generating any necessary power like slack bus. [1] Bus type (PQ bus or PV bus) BUS Bus type Comments BUS 2 PQ Bus Generator is disconnected to Bus 2 BUS 3 PV Bus Generator is connected to Bus 3 and the magnitude of voltage of generator keep constant by using AVR In general, each bus in the power system can be categorized into three bus types such as Slack Bus, Load (PQ) Bus, and Voltage Controlled (PV) Bus. The definition and difference between PQ Bus and PV Bus are described as follows; [2] PV Bus (Generator Bus or Voltage Controlled Bus): It is a bus at which the magnitude of the bus voltage is kept constant by the generator. Even though the bus has several generators and load, if any generators connected to the bus regulate the bus voltage with AVR, then this bus is referred to PV Bus. For PV bus, the magnitude of the bus voltage and real power supplied to the system are specified, and reactive power and angle of the bus voltage are accordingly determined. If a preset maximum and minimum reactive power limit is reached, the reactive output of the generator remains at the limited values, so the bus can be considered as PQ Bus instead of PV Bus. [2] PQ Bus (Load Bus): It is a bus at which the voltage is changed depending on total net real power and reactive power of loads and generators without voltage regulator. Therefore, in the power simulation and calculation, the real power and reactive power of the loads are specified as input data and accordingly the voltage (magnitude and angle) is calculated based on the above input. The following table specifies input and output of each bus type in the power system simulation and calculation. Bus Type P Q (Magnitude) ÃŽÂ ´ (Angle) PQ Bus Input Input Output Output PV Bus Input Output Input Output Slack Bus Output Output Input Input System Balance Total Generation Load Demand BUS Real Power (MW) Imaginary Power (Mvar) Generation Load Generation Load BUS 1 204.093 100 56.240 0 BUS 2 0 200 0 100 BUS 3 200 100 107.404 50 Total 404.093 400 163.644 150 Difference Pgen Pdemand = 4.093 Qgen Qstored in load = 13.644 Reason: Real power loss due to resistance of transmission line and imaginary power storage due to reactance of transmission line are the reasons for the difference between power generation and load demand in the system. P (Losses) Q (Storage) over the transmission line BUS Real Power (MW) Imaginary Power (Mvar) Sending Receiving Losses Sending Receiving Stored BUS 1 BUS 2 102.714 100.650 2.064 56.653 49.773 6.88 BUS 1 BUS 3 1.379 1.378 0.001 0.4141) 0.4131) 0.001 BUS 3 BUS 2 101.378 99.350 2.028 56.990 50.227 6.763 Total Plosses = 4.093 Qstored in load = 13.644 1) Imaginary power flows from Bus 3 to Bus 1. The summation of real power losses and imaginary power storage over the transmission line are exactly same with total difference between generation and load. Therefore, it is verified that the difference is shown over the transmission line. Kirchoff balance as each bus [4] Bus1 ÃŽÂ £ P1 = + Pgen1 Pload1 P12 P13 = 204.093 100 102.714 1.379 = 0 ÃŽÂ £ Q1 = + Qgen1 Qload1 Q12 Q13 = 56.24 0 56.653 + 0.413 = 0 Bus2 ÃŽÂ £ P2 = + Pgen2 Pload2 P21 P23 = 0 200 + 100.65 + 99.35 = 0 ÃŽÂ £ Q2 = + Qgen2 Qload2 Q21 Q23 = 0 100 + 49.773 + 50.227 = 0 BUS3 ÃŽÂ £ P3 = + Pgen3 Pload3 P31 P32 = 200 100 + 1.378 101.378 = 0 ÃŽÂ £ Q3 = + Qgen3 Qload3 Q31 Q32 = 107.404 50 0.414 56.99 = 0 According to the calculation above, as summation of incoming outgoing real power and imaginary power at each bus become zero, it is verified that each busbar obeys a Kirchoff balance. In addition, the total power system is completely balanced, because total generation power (real imaginary) are equal to summation of total load demand and real power loss stored imaginary power over the transmission (i.e. Pgen Pdemand = Plosses, Qgen Qstored in load = Q stored in system) as shown above. Voltage Angle and Angle Difference As a result of the Powerworld, the voltage angle and angle difference are shown in the table below. BUS Voltage Angle Voltage Angle Difference BUS1 ÃŽÂ ´1 = 0.00 ° BUS1- BUS2 ÃŽÂ ´1 ÃŽÂ ´2 = 0.00 ° (-2.5662 °) = 2.5662 ° BUS2 ÃŽÂ ´2 = -2.5662 ° BUS2- BUS3 ÃŽÂ ´2 ÃŽÂ ´3 = -2.5662 ° (-0.043 °) = -2.5232 ° BUS3 ÃŽÂ ´3 = -0.043 ° BUS3- BUS1 ÃŽÂ ´3 ÃŽÂ ´1 = -0.043 ° 0.00 ° = -0.043 ° Power System Analysis -1 The table below summarizes generation and voltage angle variation at each bus as generation at Bus 3 varies from 0 MW to 450 MW by 50MW. Simulation Results and Observation P3 = 0 MW P3 = 50 MW P3 = 100 MW P3 = 150 MW P3 = 250 MW P3 = 300 MW P3 = 350 MW P3 = 400 MW P3 = 450 MW Reactive Power Generation at Bus 3: It is found that reactive power generation Q3(gen) decrease while real power generation P3(gen) increase because Bus 3 as a PV Bus regulates the constant bus voltage magnitude by controlling excitation of the generation through the AVR. Power Generation at Bus 1: It is found that P1(gen) decreases and Q1(gen) increases simultaneously, while P3(gen) increases and Q3(gen) decrease. As the total load demand in the system keeps constant (i.e. Ptotal(load) = 400 MW, Qtotal(load) = 150Mvar), any necessary real power and reactive power for the system balance need to be supplied by generator (slack generator) at Bus 1. Therefore, power generation P1(gen) and Q1(gen) at Bus 1 change reversely compared to power generation change at Bus 3. Voltage Angle Difference: In general, real power flow is influenced by voltage angle difference between sending bus and receiving bus according to PR =. Therefore, it is observed that as real power generation P3(gen) increases real power flow from Bus 3 to Bus2 increase, accordingly voltage angle difference (ÃŽÂ ´3 ÃŽÂ ´2) between Bus 3 and Bus 2 increases. However, decrease in real power from Bus 1 to Bus 2 due to increase of P3(gen) result in decrease of voltage angle difference (ÃŽÂ ´1 ÃŽÂ ´2). In addition, Real power between Bus 1 and Bus 3 flows from Bus 1 to Bus 3 until P3(gen) reach to 200 MW and as P3(gen) increase more than 200 MW the real power flows from Bus 3 to Bus 1. So, it is also observed that voltage angle difference (ÃŽÂ ´3 ÃŽÂ ´1) is negative angle when P3(gen) is less than 200MW and the difference increase while P3(gen) increase. Power System Analysis -2 The table below summarizes the variation of power generation and voltage angle difference at each bus when the load demand at Bus 3 varies by 50MW and 25Mvar. Simulation Results and Observation P2 = 0 MW Q2 = 0 MW P2 = 50 MW Q2 = 25 MW P2 = 100 MW Q2 = 50 MW P2 = 150 MW Q2 = 75 MW P2 = 250 MW Q2 = 125 MW P2 = 300 MW Q2 = 150 MW P2 = 350 MW Q2 = 175 MW P2 = 400 MW Q2 = 200 MW P2 = 450 MW Q2 = 225 MW Power Generation at Bus 1 and Bus 3: It is observed that as the total load demand in the system increases due to increase of load demand P2(load) Q2(load) at Bus 2, any necessary real power for the system balance is supplied by generator (slack generator) at Bus 1 considering constant P3(gen), so P1(gen) increases. In addition, any necessary reactive power for the system balance is supplied from Bus 1 as well as Bus 3, so both Q1(gen) and Q3(gen) increase. Voltage Angle Difference: It is found that real power flow increase both from Bus 1 to Bus 2 and from Bus 3 to Bus 2 due to increase of load demand at Bus2. Accordingly, both voltage angle difference ÃŽÂ ´1 ÃŽÂ ´2 and ÃŽÂ ´3 ÃŽÂ ´2 increase when the power flow P12 and P32 increase. In addition, when P2(load) is less than 200 MW, P1gen is relatively low. Therefore real power between Bus 3 and Bus 1 flows from Bus 3 to Bus 1 at lower P2(load) (less than 200MW). On the other hand, while P2(load) increase more than 200 MW, the real power flow direction changes (Bus 1 to Bus 3) and the real power flow increases. Accordingly, the voltage angle difference ÃŽÂ ´1 ÃŽÂ ´3 change from negative to positive and increase. Voltage Magnitude at Bus 2: It is observed that magnitude of bus voltage at Bus2 drops due to increase of the load demand at Bus 2. Question 2 System Model Admittance Matrix In order to construct the admittance matrix of Powerworld B3 case, single phase equivalent circuit can be drawn as below; z = r + jx (r = 0, x = 0.05) z12 = z21= j0.05 pu, y12 = 1/ z12 = 1/j0.05 = -j20 pu = y12 z13 = z31= j0.05 pu, y13 = 1/ z13 = 1/j0.05 = -j20 pu = y31 z23 = z32= j0.05 pu, y23 = 1/ z23 = 1/j0.05 = -j20 pu = y32 Admittance matrix can be defined as follows; BUS = Diagonal elements Y(i,i) of the admittance matrix, called as the self-admittance [lecture slide] [6], are the summation of all admittance connected with BUS i. = y12 + y13 = -j20 j20 = -j40 pu = y21 + y23 = -j20 j20 = -j40 pu = y31 + y32 = -j20 j20 = -j40 pu Off diagonal elements Y(i,j) of the admittance matrix, called as the mutual admittance [lecture slide] [6], are negative admittance between BUS i and BUS j. = y12 = -(-j20) = j20 pu = y13 = -(-j20) = j20 pu = y21 = -(-j20) = j20 pu = y23 = -(-j20) = j20 pu = y31 = -(-j20) = j20 pu = y32 = -(-j20) = j20 pu Therefore, the final admittance matrix BUS is; BUS = = The following figure shows the BUS of the Powerworld B3 case and it is verified that the calculated admittance matrix is consistent with the result of the Powerworld.
