Distribution-free confidence bands for a distribution function are typically obtained by inverting a distribution-free hypothesis test. We propose an alternate strategy in which the upper and lower bounds of the confidence band are chosen to minimize a narrowness criterion. We derive necessary and sufficient conditions for optimality with respect to such a criterion, and we use these conditions to construct an algorithm for finding optimal bands. We also derive uniqueness results, with the Brunn–Minkowski Inequality from the theory of convex bodies playing a key role in this work. We illustrate the optimal confidence bands using some galaxy velocity data, and we also show that the optimal bands compare favorably to other bands both in terms of power and in terms of area enclosed. 相似文献

Many programs that place low-income students of color in high-achieving college preparatory high schools seek to nurture bridging social capital, connections across class lines that provide leverage in the process of “getting ahead.” Bonding social capital, which focuses more on emotional support and “getting by,” is frequently characterized as less useful for social mobility. Drawing upon in-depth interviews with alumni from one such program, we challenge the notion of bridging and bonding social capital as discrete, countervailing forms of social capital, and demonstrate how the two may complement each other. Specifically, we find that bonding social capital served as a critical resource that students drew upon as they navigated their elite high schools in the face of racism and classism. In doing so, this bonding social capital ultimately facilitated the development of bridging social capital by encouraging student persistence at these institutions. Our findings support critiques of traditional accounts of social capital that devalue the capital possessed by marginalized communities and fuel deficit ideologies. Furthermore, they highlight the personal costs that youth may face in the pursuit of bridging capital, complicating the narrative of social mobility as an unmitigated good. 相似文献

Non-standard work schedules (NSWS) have become typical, but their associations with childcare arrangements and children's well-being are unknown. This study explores how risk factors are associated with the social–emotional well-being of girls and boys using flexibly scheduled early childhood education and care. Furthermore, the study investigates whether well-functioning cooperation between parents and educators buffers the negative effects of the risk factors. This study, which is a part of a larger survey carried out in three European countries, reports Finnish parents' (N = 146) perspectives. The results showed that high parental stress was associated with low child well-being. Strong parent–educator cooperation positively impacted both boys' and girls' social–emotional well-being. The risk factors of reconciling work and family life had negative associations with children's well-being and the fulfilment of their basic needs. The results illustrate the complex interrelations between children's well-being, risk factors relating to NSWS and the buffering effect of protective factors. 相似文献

In the “k-volunteer's dilemma” benefit accrues to all members if at least k members volunteer, and receive nothing otherwise. We use experiments to examine (a) volunteering behavior when threshold k increases from 1 to 2, and (b) whether volunteering behavior shifts toward norms associated with one of two primed identities—charitable or competitive. We find that increasing the threshold increases an individual's probability of volunteering, but the likelihood of good provision is lower. Neither priming affects volunteering behavior when k = 1, but competitive priming effectively increases volunteering when k = 2. Both greed and fear of non-provision appear to affect volunteering. 相似文献

Using data from the Korean Labor and Income Panel Study (KLIPS), recent trends in intergenerational income mobility were explored, examining the relationship between income mobility and income inequality in South Korea. The study found that the intergenerational elasticity of income is about 0.2 and there is no clear‐cut trend in intergenerational income mobility. In addition, this study showed that there is no systematic relation between rising income inequality and intergenerational income mobility in contemporary Korea. Overall, the results indicate that intergenerational income mobility is irresponsive to the income inequality the respondents experienced growing up. It is assumed that education and welfare transfer programs might offset the consequences of income inequality by leading to upward mobility for children from low‐income households. 相似文献

Children live in different contexts of protection and vulnerability when exposed to domestic violence. The negative impacts for many children are consistent and widely acknowledged. However, the implication that this requires men who use violence to address their fathering has been slower to emerge. This article draws from 69 in‐depth qualitative interviews with men, women, and workers across four men's behaviour change programmes in rural Victoria, Australia. Particular attention is given to men's attitudes to their fathering and the formal and informal consequences they experienced as a result of their violence and its impact on their fathering. Although most men came to recognize that their violence impacted their children, they failed to make the connection that the involvement of statutory child protection services in their lives was a direct consequence of their abusive behaviour. This article explores this disconnection by fathers who use violence, their attitude to the involvement of statutory child protection services, and identifies the implications for social work practitioners in addressing this issue. 相似文献

Axford N. Children and global social policy: exploring the impact of international governmental organisations International governmental organisations (IGOs) seek to influence child welfare policy and practice in individual sovereign states. But do they succeed and, if so, in what way? This article outlines the nature of selected IGOs' work, explores the nature of their impact and seeks to explain the pattern that emerges. It also notes areas for further research. 相似文献

Over the past two decades, child protection authorities internationally have begun to implement models of family participation in child protection decision‐making. Debate exists about the extent to which these models promote family involvement in decision‐making. While a significant body of research on family and professional experience and perceptions of models of family participation in decision‐making has emerged, there has been little observational research of these approaches. In this paper, we report on observational data from 11 family group meetings (FGMs) in a child protection context in Queensland, Australia. Under Queensland child protection law, these meetings are referred to as an inclusive process for child protection decision‐making and planning. We draw on observational data to analyse how family inclusion in child protection decision‐making is facilitated, or limited, by the FGM process. We consider tensions in the realization of a participatory ethos in child protection services systems and discuss what practitioners can practically do to enhance family participation in child protection decision‐making. 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

Understanding the experience of women who become mothers during their teenage years is central to ensuring that the support that is offered is appropriate to meet their needs. This paper reports on a small part of a larger ethnographic study that captured the lived experience of young mothers who were between the ages of 16 and 19 years that potentially typifies and illuminates the experiences of young women who become mothers in their teenage years. By collecting data from narrative interviews as well as participant and non‐participant observations over an extended period of time it was possible to identify how the young women experienced a range of difficulties as they made their transition into motherhood. Drawing on the findings, this paper argues that this transition for teenage mothers can be significantly different from the experience of older mothers, and it identifies the importance of appropriate support to mediate the challenges that they face. Understanding the young women's journey to ‘becoming’ is critical when planning services because if their experience of support is negative, it can lead to increased levels of maternal stress and reluctance to engage with support services. 相似文献
