We consider resource allocation problems where inputs are allocated to different entities such as activities, projects or departments. In such problems a common goal is achieving a desired balance in the allocation over different categories of the entities. We propose a bi-criteria framework for trading balance off against efficiency. We define and categorise indicators based on balance distribution and propose formulations and solution algorithms which provide insight into the balance-efficiency tradeoff. We illustrate our models by applying them to the data of a portfolio selection problem faced by a science funding agency and to randomly generated large-sized problem instances to demonstrate computational feasibility.  相似文献

ABSTRACT

Stress-related conditions such as burnout and post-traumatic stress disorder are a growing concern in the humanitarian sector. Aid workers themselves report not only that mental health problems are common, but that the support they receive from their employers is insufficient. Problematically, the experience of the international aid worker – particularly those who are white and from the global North – is often foregrounded in explaining what constitutes stress and related mental health problems. This indicates a wider problem of what is required of ‘the perfect humanitarian’ – a personality that is gendered and racialised – and how this influences the different experiences and treatment of national and international staff from aid agencies. This article explores the organisational culture and working conditions of humanitarian settings and their impact on the mental health and well-being of staff. It argues that there is a structural dimension to stress that is less to do with external security threats and more to do with the specific infrastructure, policies, and practices of humanitarian operations, with implications for aid workers which cut across dimensions of race, gender, and nationality.  相似文献

Diverse coalitions hold great potential for social movements, but they also face tremendous challenges. In this article, I review the literature on diverse alliances with a focus on how trust, commitment, and ultimately, solidarity can be developed and sustained across divides. The article begins by discussing the needs of diverse alliances to build trust and commitment, and the coalitional characteristics deemed vital for doing so, with a focus on shared neutral space, ongoing interaction, and social ties and bridgebuilders. Five coalitional processes and practices are identified and discussed that have been empirically found or theorized to be imperative for cultivating solidarity across difference and inequality. These processes include (a) uniting around shared principles while engaging difference; (b) acknowledging and managing inequalities; (c) making space for each other; (d) attention to managing conflicts; and (e) actions that confirm the shared commitments and negotiated identity. I conclude by evaluating the state of research on developing and sustaining alliances across divides.  相似文献

Suburbs across the US are experiencing dramatic demographic shifts, yet there is little research available on how suburban school districts are dealing with these changes. In this article, we examine the discourses surrounding race and demographic change in three suburban school districts that have been undergoing rapid demographic changes and which contain demographically distinct areas within their district boundaries. Utilizing a critical discourse analysis (CDA) approach, we analyze how the policy context (federal and state) frames actors’ discourses and understandings of race, paying particular attention to the political and institutional factors affecting school policy. We illustrate how the discourse, in turn, is related to the actions (or inactions) taken by district and school leaders to respond to demographic change. We conclude the article by discussing policy implications and potential challenges districts may face in the future if efforts to purposively address racial changes continue to be avoided.  相似文献

This paper is an account and critical analysis of the psychodynamic and systemic consultancy that the author provided to a care home (and the voluntary organisation running it) over a period of about 16 months. In addition two emergent, linked themes are identified and discussed: family and gender roles in care homes, and racism and colonialism. Care homes are of course part of the society in which they exist and of which they are a product. This means that all the overt and covert psychological and social pressures, defences and trends that occur in the wider society, for individuals, families, groups and communities are also to be found in care homes and in the organisations that run them. They are not isolated from these forces, indeed, it is argued in this paper, the forces are intensified in the ‘hot house’ environment of a care home and, if ignored, avoided and denied, result in the exploitation, abuse and neglect of both staff and residents.  相似文献

This article compares North Korean immigrants and foreign bride policies in South Korea. Despite being constructed as distinctive policy target groups, North Korean settlement and foreign bride incorporation policies exhibit striking similarities. The similarities result from the way policy problems are identified and certain solutions are justified; both North Korean immigrants and foreign brides are constructed a burden on welfare and as potential threats to social stability. Policy solutions are justified as they are designed to transform North Korean immigrants and foreign brides into ‘normal’ South Korean citizens. The major difference between two sets of policies lies in assumptions regarding cultural differences. Foreign brides are assumed to carry practices that are foreign and alien to Koreans, while North Korean immigrants are presumed to carry ‘authentic’ and ‘traditional’ Korean culture. Foreign brides’ cultures are visible and alien to South Koreans, and therefore are addressed under the banner of multiculturalism policies. North Korean immigrants are excluded from such policies. This exclusion reflects and reproduces the view of a Korean nation bounded by ethnic and cultural homogeneity.  相似文献

Lack of data on daily inhalation rate and activity of children has been an issue in health risk assessment of air pollutants. This study aimed to obtain the daily inhalation rate and intensity and frequency of physical activity in relation to the environment in Japanese preschool children. Children aged four–six years (n= 138) in the suburbs of Tokyo participated in this study, which involved three days' continuous monitoring of physical activity using a tri‐axial accelerometer and parent's completion of a time/location diary during daily life. The estimated three‐day mean daily inhalation rate (body temperature, pressure, saturated with water vapor) was 9.9 ± 1.6 m3/day (0.52 ± 0.09 m3/kg/day). The current daily inhalation rate value of 0.580 m3/kg/day proposed for use in health risk assessment in Japan is confirmed to be valid to calculate central value of inhaled dose of air pollutants in five‐ to six‐year‐old children. However, the 95th percentile daily inhalation rate of 0.83 m3/kg/day based on measurement for five‐year‐old children is recommended to be used to provide an upper bound estimate of exposure that ensure the protection of all five‐ to six‐year‐old children from the health risk of air pollutants. Children spent the majority of their time in sedentary and light level of physical activity (LPA) when indoors, while 85% of their time when outdoors was spent in LPA and moderate‐to‐vigorous physical activity. The results suggest the need to consider variability of minute respiratory ventilation rate according to the environment for more refined short‐term health risk assessment.  相似文献

Schoemaker J, Twikirize J. A life of fear: sex workers and the threat of HIV in Uganda The way individuals perceive their risk to certain threats influences their adoption of preventive behaviour. This study explored sex workers' perception of risk of HIV infection within the context of other serious threats. The study was carried out in Kampala, Uganda, using peer ethnography. Sex workers were well aware of their risk of HIV infection but this risk was eclipsed by other more immediate and frightening threats. Sex workers' willingness to gamble with HIV is explained by the fact that their existence is already very dangerous, and taking risks is an inherent part of their trade. Decriminalising sex work could make their lives somewhat safer, motivating them to better protect themselves, but this is unlikely to happen in Uganda. Attempting to enforce some coercive control mechanisms would not work, given the pervasive corruption in law enforcement and the judiciary, the institutions that would be responsible for implementing such control.  相似文献

The Victorian Child Death Review Committee (VCDRC) in Australia is a multidisciplinary Ministerial Advisory Committee established to review the deaths of children either currently child protection clients or known to the statutory child protection system. The Committee provides advice about each child death as well as insights into what are the surrounding patterns and issues. Key to this role is examining the contribution of the service sectors to the protection of children and the routine practices that are in place to respond to children and vulnerability. This paper provides a snapshot of the cases referred to the VCDRC and the key messages for practice drawn from them. What emerges is that often the threshold for when statutory child protection services must be involved in child and family matters can be ambiguous and that agreement about intervention, the level and nature of need or risk, and when cumulative harm and neglect require statutory responses are not always shared between agencies. It is clear that the lack of common frameworks about what constitutes child protection intervention challenges services. It is recommended that there be and used agreed definitions and frameworks to ensure shared understandings and collaborative responses across the service and legal systems.  相似文献

Non‐governmental organizations (NGOs) and the government of Nepal have made some effort to reduce poverty in Nepal by creating women's affiliation groups, some of which are micro‐credit organizations. Using capabilities as defined by Amartya Sen (Development as freedom, Oxford University Press, New Delhi, 2000), which includes employment opportunities, women's ownership in productive resources such as land and/or homes, educational opportunities, and women's participation in decision‐making in the family, this study evaluated the extent to which women's ethnic group or caste affiliation affected a woman's likelihood of being empowered by participation in these groups. We analyzed a sample of 8,973 women which was taken from the 2011 Nepal Demographic and Health Survey. Previous research has demonstrated that participation in gender‐based groups is correlated with higher economic status. This study adds to the literature on women's affiliation groups by investigating the impact of structural factors, such as caste and ethnicity, on women's self‐help group participation (women's groups and credit groups).  相似文献
