At what ages should managers be recruited? Are the young managers receiving the right sort of experience at an early stage in their careers? What effect will the proposed merger have on the career prospects in the company.....? Questions such as these are likely to face every company from time to time, but finding the answers can be very difficult. The task may be made much easier through the application of some simple analytical techniques. These techniques are discussed here in the form of a case study.  相似文献

Graphs that arise from the finite element or finite difference methods often include geometric information such as the coordinates of the nodes of the graph. The geometric separator algorithm of Miller, Teng, Thurston, and Vavasis uses some of the available geometric information to find small node separators of graphs. The algorithm utilizes a random sampling technique based on the uniform distribution to find a good separator. We show that sampling from an elliptic distribution based on the inertia matrix of the graph can significantly improve the quality of the separator. More generally, given a cost function f on the unit d-sphere Ud, we can define an elliptic distribution based on the second moments of f. The expectation of f with respect to the elliptic distribution is less than or equal to the expectation with respect to the uniform distribution, with equality only in degenerate cases. We also demonstrate experimentally that the benefit gained by the use of the additional geometric information is significant. Some previous algorithms have used the moments of inertia heuristically, and suffer from extremely poor worst case performance. This is the first result, to our knowledge, that incorporates the moments of inertia into a provably good strategy.  相似文献

This paper reports the results of a qualitative inquiry into the aetiology of anorexia nervosa in Hong Kong. These results are part of our main research project about family treatment and families with a daughter suffering from anorexia nervosa. This present qualitative study adopts a multiple case study approach (n = 8) and employs a multiple‐source data collection method, involving pre‐ and post‐family treatment interviews, clinical observations of the participants during the treatment sessions and home visits, as well as detailed field notes. The findings indicate that there are biological, psychological, socio‐cultural and familial interpretations of the aetiology of anorexia nervosa. This study challenges the dominant discourse on anorexia nervosa in Hong Kong, which states that the root of the disease lies in a desire for slenderness and beauty, and suggests instead that the aetiology of anorexia nervosa can be discovered only if approached from the systems level. Implications for social work practice are highlighted.  相似文献

Contemporary debates are increasingly pessimistic about the impact of ethnic diversity on support for the welfare state. A growing number of analysts argue that greater ethnic diversity in Western democracies is weakening public support for redistribution, and that this underlying tension is exacerbated by the adoption of robust multiculturalism policies. The purpose of this essay is to summarize early findings from several studies that bear on the questions at the heart of such debates. These studies analyse the implications of immigration and multiculturalism policies for the welfare state across OECD countries, and also focus more closely on the experience of two distinctively multicultural countries, the United States and Canada. The evidence points to more complex relationships than often assumed. OECD countries with large foreign‐born populations have not had more difficulty in sustaining their welfare states than other countries. The extent of change does seem to matter, however, as countries in which immigrant communities grew rapidly between 1970 and the late 1990s did experience lower rates of growth in social spending. But despite the warnings of some critics, robust multiculturalism policies do not systematically exacerbate this tension. Moreover, the United States and Canada reflect different patterns. In the US racial diversity does weaken support for redistribution; but Canadian experience suggests that immigration, multiculturalism policies and redistribution can represent a stable political equilibrium. These contrasting narratives from North America stand as a warning against premature conclusions based on the US experience alone. There is no inevitability at work, and policy choices do seem to matter.  相似文献

Do lawyer-legislators differ significantly from their non-lawyer colleagues? This question is significant given the large number of lawyers occupying state and federal legislatures. The predominant theory of “professional convergence” holds that lawyer-legislators and non-lawyer-legislators exhibit no significant differences. In examining the Ohio General Assembly, this study finds that lawyers tend to be more ambitious, and think of their legislative roles differently than their non-lawyer associates. The study concludes that convergence theory needs to be revised to become attuned to present day realities of law and politics.  相似文献

This meta‐analysis finds that parents report lower marital satisfaction compared with nonparents (d=?.19, r=?.10). There is also a significant negative correlation between marital satisfaction and number of children (d=?.13, r=?.06). The difference in marital satisfaction is most pronounced among mothers of infants (38% of mothers of infants have high marital satisfaction, compared with 62% of childless women). For men, the effect remains similar across ages of children. The effect of parenthood on marital satisfaction is more negative among high socioeconomic groups, younger birth cohorts, and in more recent years. The data suggest that marital satisfaction decreases after the birth of a child due to role conflicts and restriction of freedom.  相似文献

This study reports the friendship experiences and aspirations of adults with intellectual disabilities. The findings of a larger study were reviewed by an expert group of self-advocates with intellectual disability. The expert group confirmed some of the interpretation of the original data and expanded on issues. Friendship is established as an issue of concern among adults with intellectual disability. Consequently, policy-makers and service providers need to be intentional about providing support for friendships. Participants asserted a positive self-identity of being a person with intellectual disability and how this could be a basis for friendship. Also, people with intellectual disability demonstrated how they should be considered experts in their own life experience and how they can be effectively included in the formulation, implementation, analysis and review of research.  相似文献

In the past four decades, Hong Kong has seen a dramatic transformation of the social location of women in the public sphere, with deep and far-reaching ramifications for courtship, marriage, fertility, conceptions of parenthood, familial power, and equality and freedom. A sociology of the family is thus by necessity a sociology of women in particular, and of gender relations in general. Indeed, recent developments in research on marriage and the family in Hong Kong reflect this new awareness. Using rigorous sociological frameworks, this new line of research has begun to meet with some success in analyzing contemporary social issues that are prominent in the public consciousness. This essay reviews studies of four topical areas: determinants of the postponement of first marriage among women, the effect of live-in foreign domestic workers on family dynamics, violence against women and children in the family, and the livelihood strategies of cross-border families. These studies have attempted to integrate the interplay of the impact of a changing economy and society on the family and the role played by women in the family. The resulting dynamic interactions amongst the members within the family and the changes they bring about become propellants for change in the economy and society and pose new challenges. The family is indeed a troubled institution. It is so because myriad public issues are being taken on, confronted, worked through, and acted out within the family. The agony, and indeed the ecstasy, of the family is a reflection of the success, and failure, of society.  相似文献
