This article focuses on the contributions and, importantly, the limitations of subjective wellbeing (happiness/satisfaction) measures as indicators of broad population wellbeing and societal functioning. The popular practice of comparing happiness among countries gives a skewed view of how well their people are faring. Charting trends over time in happiness and mental health gives contradictory pictures of population wellbeing; even the responses to different questions within the same survey can yield very different findings. Asking people about their own lives and about social conditions produces contrasting results. These issues challenge the orthodox model of human development, which places Western liberal democracies at its leading edge. According to an alternative, psychosocial-dynamics, model, some, at least, may be societies in decline. Reconciling these views is no simple matter.  相似文献

Criminologists have long reported the existence of racial disparity in the criminal justice system, but the important question is why. While some argue that observed differences are a consequence of more criminal behavior among minorities, the weight of the evidence indicates that this is but a partial explanation. In this paper, we study data from a sample of juveniles to examine how racial differences in early police contact, and important social environments—family, school, and neighborhoods—affect later contact and arrests, controlling for self-reported delinquency. We find that early (in middle school) contact with police is an important predictor of later (high school) arrests. Also we found that, in addition to being male and living in a low-income family, children who have parents who have a history of arrest, who have experienced school disciplinary actions, who have delinquent peers, and who are in networks with deviant adults are more likely to have problems with law enforcement. These factors help to explain racial differences in police contacts and arrests.  相似文献

Abstract

Robert Cox developed a potent approach to studying world orders that is premised on the capacities of a special intellectual, the critical theorist, to discern social structures and the possibilities for their radical change in the future. While acknowledging the ethical appeal of adopting this intellectual persona, in this paper we are concerned with the style of historiography that it requires. In particular, we argue that the imperative to discover and foster the beginnings of social change leads to a version of philosophical history that will likely produce systematic anachronism. This is not uncommon in the discipline of International Relations, but in the case of Cox it stands in tension with some of his avowed intellectual sources, especially the work of Giambattista Vico, and with the aim of providing critical historical perspective on the present. We argue that Vico stands as an example of an alternative historical-empirical line of research that would better serve Coxian ambitions.  相似文献

Research suggests the relationship between pleasure and condom use during penile–vaginal intercourse (PVI) is associated with relationship status. This online study examined pleasure ratings and condom use at last PVI, stratifying by partner type, among a national sample of Canadian university students. Participants were 715 undergraduates (60.7% women, 39.3% men) who reported on their most recent sexual experience. Condom use decreased with level of relationship commitment, whereas ratings of pleasure increased. Overall, participants were more likely to rate their most recent PVI as Very pleasurable when condoms were not used compared to when condoms were used. However, when stratified by partner type, these differences largely disappeared. For women, with one exception, there were no differences in pleasure between PVI with and without condoms across most partner-type categories. Women in committed dating relationships were more likely to report their last PVI as very pleasurable if condoms were not used than women in these same relationships who had used condoms. Across relationship categories, men who did and did not use condoms did not differ in terms of their pleasure ratings. The results of this study suggest relationship context should be taken into account when assessing condom use experiences.  相似文献

In response surface methodology, one is usually interested in estimating the optimal conditions based on a small number of experimental runs which are designed to optimally sample the experimental space. Typically, regression models are constructed from the experimental data and interrogated in order to provide a point estimate of the independent variable settings predicted to optimize the response. Unfortunately, these point estimates are rarely accompanied with uncertainty intervals. Though classical frequentist confidence intervals can be constructed for unconstrained quadratic models, higher order, constrained or nonlinear models are often encountered in practice. Existing techniques for constructing uncertainty estimates in such situations have not been implemented widely, due in part to the need to set adjustable parameters or because of limited or difficult applicability to constrained or nonlinear problems. To address these limitations a Bayesian method of determining credible intervals for response surface optima was developed. The approach shows good coverage probabilities on two test problems, is straightforward to implement and is readily applicable to the kind of constrained and/or nonlinear problems that frequently appear in practice.  相似文献

Summary.  Data in the social, behavioural and health sciences frequently come from observational studies instead of controlled experiments. In addition to random errors, observational data typically contain additional sources of uncertainty such as missing values, unmeasured confounders and selection biases. Also, the research question is often different from that which a particular source of data was designed to answer, and so not all relevant variables are measured. As a result, multiple sources of data are often necessary to identify the biases and to inform about different aspects of the research question. Bayesian graphical models provide a coherent way to connect a series of local submodels, based on different data sets, into a global unified analysis. We present a unified modelling framework that will account for multiple biases simultaneously and give more accurate parameter estimates than standard approaches. We illustrate our approach by analysing data from a study of water disinfection by-products and adverse birth outcomes in the UK.  相似文献

This paper characterizes vulnerable workers in Canada and the federal jurisdiction, based upon characteristics such as employment status, demographic characteristics, and job characteristics, and identifies areas in which labour standards may have a role. Based on this analysis, the paper evaluates the potential for labour standards to address economic vulnerability, focusing on labour standards policies aimed at wages and benefits, hours, and employment arrangements. In addition, the analysis considers the extent to which labour standards are likely to reach vulnerable workers. The results suggest several potential roles for labour standards and highlights policy implications.

Abstract Recent initiatives from state and federal government agencies have helped foster the formation of community‐based watershed organizations. Although there is a great deal of enthusiasm about the potential of these organizations to enhance water quality, relatively little attention has been paid to the impacts these organizations may have on the well‐being of rural communities more generally. Assessments of effectiveness have typically focused on specific activities and accomplishments, rather than a broader range of community‐based effects. In short, we ask whether community‐based environmental management improves community as well as environment. Our research utilized a mixed‐methods design, including a statewide mail survey of all Pennsylvania watershed organizations, followed by in‐depth interviews with 28 rural watershed organizations. This sequential approach progressively explored in more detail definitions of effectiveness, including the building of rural capacity. We find watershed organizations are potentially effective mechanisms for building local leadership, enhancing the skills of rural residents, and making valuable connections with other communities, facing similar water‐resource and rural‐development issues. However, the range of issues with which local watershed organizations engage and the methods they currently utilize may eventually limit their usefulness.  相似文献

The article “Emergence of an academic elite? The impact of universities’ size and reputation on research funding” by Katrin Auspurg, Thomas Hinz and Jürgen Güdler (volume 4/2008 of this Journal) discusses critically Richard Münch’s thesis of monopolistic tendencies in the German science system. Unfortunately the authors focus in their analysis on an improper object, the “Individual grants programme” (Normalverfahren) of the German Research Foundation (DFG). However, problematic developments for the German science system will rather result from the “Coordinated grants programmes” (koordinierte Programme), in particular the excellence initiative. Furthermore the authors fail to connect their analysis to the broader context of the functions and implications of the increasing role of third party funding in the German science system.  相似文献
