We estimate a dynamic model of employment, human capital accumulation—including education, and savings for women in the United Kingdom, exploiting tax and benefit reforms, and use it to analyze the effects of welfare policy. We find substantial elasticities for labor supply and particularly for lone mothers. Returns to experience, which are important in determining the longer‐term effects of policy, increase with education, but experience mainly accumulates when in full‐time employment. Tax credits are welfare improving in the U.K., increase lone‐mother labor supply and marginally reduce educational attainment, but the employment effects do not extend beyond the period of eligibility. Marginal increases in tax credits improve welfare more than equally costly increases in income support or tax cuts. 相似文献

Inequality indexes have long been used to analyze distributions of income. Studies have recently begun to use these tools to evaluate the equity of distributions of environmental harm. In response, issues have been raised regarding the appropriateness of using income-based measures in the context of undesirable outcomes. We begin from first principles, identifying a theoretical preference structure under which income-based tools can be appropriate for ranking distributions of “bads.” While some critiques of existing applications are valid, they are not a justification for rejecting the approach altogether. Instead, we show how standard income-based measures can be adjusted to accommodate bad outcomes. Rather than inequality indexes, we argue that equally distributed equivalents (EDEs) are well-suited for this purpose since they account for levels and dispersion of outcome distributions. The Kolm–Pollak EDE is particularly useful, having the advantage of consistently evaluating both bads and their complementary goods (e.g., mortality risk and survival probability). As an illustration, we show how these tools can inform an environmental justice analysis of a proposed Environmental Protection Agency (EPA) rule addressing indoor air pollution. 相似文献

The accelerated failure time (AFT) models have proved useful in many contexts, though heavy censoring (as for example in cancer survival) and high dimensionality (as for example in microarray data) cause difficulties for model fitting and model selection. We propose new approaches to variable selection for censored data, based on AFT models optimized using regularized weighted least squares. The regularized technique uses a mixture of \(\ell _1\) and \(\ell _2\) norm penalties under two proposed elastic net type approaches. One is the adaptive elastic net and the other is weighted elastic net. The approaches extend the original approaches proposed by Ghosh (Adaptive elastic net: an improvement of elastic net to achieve oracle properties, Technical Reports 2007) and Hong and Zhang (Math Model Nat Phenom 5(3):115–133 2010), respectively. We also extend the two proposed approaches by adding censoring observations as constraints into their model optimization frameworks. The approaches are evaluated on microarray and by simulation. We compare the performance of these approaches with six other variable selection techniques-three are generally used for censored data and the other three are correlation-based greedy methods used for high-dimensional data. 相似文献

This study tested the distorted cognitions component of Hall and Hirschman's (1991) quadripartite model of sexual aggression. Men (N = 107) with and without hostile sexual beliefs viewed erotic slides with a female partner who provided one of four patterns of feedback: clear disinterest, token disinterest, compliant interest, and clear interest. Hostile men reported fewer differences between women, were unresponsive to their partner's perceived embarrassment, and reported a consistent positive mood regardless of her feedback. Conversely, nonhostile men were more responsive to feedback, mirrored the partner's embarrassment, and experienced a less positive mood when she communicated clear disinterest in the erotica. These findings support the distorted cognitions component of the quadripartite model of sexual aggression. The authors also discuss the strengths and limitations of this study's methodology. 相似文献

The effects of interagency collaboration on risk assessment in child protection practice were analysed in respect of the decision-making processes in child death inquiries. Universal features in the assessment of risk as identified in psychological literature were applied; in particular, the concepts of ‘groupthink’, the ‘certainty effect’ and ‘group polarization’. It is suggested that case conference decisions are inherently more risky than those taken by professionals with individual responsibility because of the way in which cases are framed in terms of losses. 相似文献

In 2017, the number of applications for care orders in England and Wales was the highest ever recorded at 14,207. This is a significant factor, contributing to the rise in the number of children who are looked after, which is at the highest level since 1985. The authors reflect on the recently published Care Crisis Review 2018, a sector‐led review, which examines the reasons for the rise in care proceedings and the number of children in care. The review sought to identify changes to policy and practice within local authorities and the family justice system, in an attempt to divert cases away from the family courts and to reduce the number of children in care, where it is safe to do so. Whilst the legislative framework is largely effective and the system generally works well, there is insufficient funding and resources to meet the needs of children and their families when they seek help, regardless of whether this is at an early stage or when they are in crisis and most in need of care and protection. 相似文献

The rural‐urban political divide has sparked media and social science concern. Yet national studies of rural and urban voters have largely failed to draw from the distinct conceptual literatures produced by rural sociologists. We take a new look at individuals’ voting choices, building from two rural sociological literatures, research on spatial inequality and on the rural‐urban continuum, to identify the social bases anteceding Republican voting in presidential elections. We analyze three social bases along which rural‐urban populations vary: social structural statuses, work and employment, and sociocultural values and beliefs. We question the degree to which rural‐urban differences can be accounted for by these factors. Data are from approximately 9,000 respondents to the General Social Surveys for election years 2000–2012. Our findings demonstrate that the literatures produced by rural sociologists provide a strong conceptual foundation for explaining rural‐urban voting differences. Rural and urban residents’ differential social statuses account for the greatest variation in their voting choices. Sociocultural values and beliefs, particularly attitudes toward domestic social issues, are also important. Findings add significant insight into the variety of factors that differentiate rural‐urban individuals’ voting choices as well as illuminate the need for greater emphasis on exurban voters. 相似文献

Although we know that high‐quality employee–organization relationships are beneficial, these relationships are complex and not fully understood, especially among employees of nonprofit organizations. In particular, we know little about how these employees perceive trust, which may overlook an important contributor to effective management. We begin to address this issue by testing a new theoretical model that conceptualizes perceived insider status, psychological ownership, and organizational identification as foundations for the perception of justice and subsequent trust. Our results indicate that psychological ownership and perceived insider status relate to trust through procedural and interpersonal justice. These results contrast those typically found in for‐profit contexts in that organizational identification did not predict justice and that distributive and informational justice did not predict trust. 相似文献

This paper studies the internal mechanisms that allow organisations to become high value manufacturing (HVM). Using a qualitative methodology, three UK manufacturing companies formed in-depth case studies with semi-structured interviews, observations and historical data. The HVM value matrix of Martinez and co-workers is used to categorise each organisation’s value proposition. Wider benchmarking of the three organisations was carried out against a focus group with an additional seven manufacturing organisations. Thus, data from 10 manufacturing organisations are included in this research. The cases follow the ‘customer intimacy’ HVM discipline. The business processes supporting these value propositions were identified. Interestingly, each organisation’s desired value proposition differs from their current one. ‘Technological integrators’ predominantly rely on new product development (NPD) and Strategy processes, whereas ‘Socialisors’ rely predominantly on Strategy and Customer Relationship processes. Companies can use the findings to better understand their current HVM value proposition and, where necessary, plan their transition to a future desired HVM value proposition. 相似文献

Since the seminal research of O'Reilly, Karen [2000. The British on the Costa del Sol. London: Routledge] and King, Russell, Anthony Warnes, Allan Williams [2000. Sunset Lives: British Retirement Migration to the Mediterranean. New York: Berg Publishers] about British citizens on the Costa del Sol there has been a surge in the publication of lifestyle migration papers, books and research. Nonetheless, there is a part of the lifestyle migration process that has been rarely explored: a return move to the country of origin following retirement migration. Research has indicated a broad increase in the number of older British returnees, yet there has been no substantive research on the topic. This paper therefore attempts to fill this gap by using Spanish registry data to examine the number of British retirees since 2009 who have returned to the UK. In addition, the results of an electronic survey to older British people in Spain are presented which suggest that considerable numbers of British citizens aged over 55 living in the Northern Costa Blanca are likely to return in the next few years. These data therefore indicate the relevance of return migration from Spain to the UK as a significant issue to the academic community as well as to British and Spanish policy-makers. 相似文献
