The study analyzed poverty as a function of households’ demographic composition using a longitudinal random sample of 4268 urban and rural households that were followed-up from 2005/6 to 2009/12 in Mexico to estimate short-term changes in living conditions. Well-being was measured as the dwelling unit’s number of rooms, water source, sanitary services, garbage disposal, and fuel. Mobility paths included not poor–not poor, poor–poor, not poor–poor, and poor–not poor. Independent variables included household composition, family characteristics, residential changes, schooling, and occupation. Female headship and older adults negatively impacted poverty, whereas economic dependents may be negatively or positively associated. Fertility incentives for low-income populations are not advisable. Working-age adults contribute only if income-generating opportunities exist locally.  相似文献

This paper proposes a hierarchical probabilistic model for ordinal matrix factorization. Unlike previous approaches, we model the ordinal nature of the data and take a principled approach to incorporating priors for the hidden variables. Two algorithms are presented for inference, one based on Gibbs sampling and one based on variational Bayes. Importantly, these algorithms may be implemented in the factorization of very large matrices with missing entries.  相似文献

This paper looks beyond more traditional evaluation activities to focus primarily on evaluation up front. It suggests that the early appraisal of an investment case or a project should apply essentially the same evaluation criteria that will be used in ex post evaluation, and thus increase the likelihood of a successful project outcome. However, the initial plan might be altered as result of subsequent analysis, assessment, negotiation, positioning, and the exercise of power. The last part of this paper presents an empirical study of 23 projects, which examines the complexity of processes that occur in the idea- and decision phases.  相似文献

When the benefit of making a correct decision is sufficiently high, even a slight increase in the probability of making such a decision justifies an increase in the number of decision makers. Applying a standard uncertain dichotomous choice benchmark setting, this study focuses on the relative desirability of two alternatives: adding individuals with capabilities identical to the existing ones and adding identical individuals with mean-preserving capabilities that depend on the states of nature. Our main result establishes that when the group applies the simple majority rule, variability in the capabilities of the new decision makers under the two states of nature, which is commonly observed in various decision-making settings, is less desirable in terms of the probability of making the correct decision.  相似文献

The effect of a positive day reflection as a technique of positive psychology has been found repeatedly. The qualitative study is based on a sample of 74 participants and shows which kind of experiences people make during and after this exercise. For this purpose, participants were instructed to reflect their day based on four specific questions (4-Evening-Questions) every evening over a period of two weeks. Subsequently, individual experiences were collected and analyzed qualitatively. The results show that the exercise leads to a sensitization of perception, a change in the interpretation of situations as well as in one’s own actions.  相似文献

徐复观认为,史学的价值必须对现实人生和民族文化有所鉴戒。他以心性史观为基础,显扬史家主体意识,认为治史的态度比方法重要。徐复观治史渊源脉络的形成有四方面的因素,对时代学风的反省批评,对熊十力思想的继承与拓展,关注日本汉学界的研究动向及汲取西方史学的理论方法。  相似文献

Research has increasingly noted that gay male adults are more at risk for developing body image dissatisfaction than other male populations. Body image issues warrant attention, particularly since they have been connected to the development of disordered eating patterns. Studies have often traced gay male body dissatisfaction to various sociocultural elements and phenomena, particularly the media. In fact, various media genres have been implicated as being instrumental in propagating idealized male physiques, which in turn may negatively influence observers. Using objectification theory, this paper aims to review the process by which media imagery are internalized by some gay men and how such internalizations harmfully impact their body image. The clinical implications and treatment of body dissatisfaction will be reviewed in terms of social work practice with gay male populations.  相似文献

We investigate the convergence rates of uniform bias-corrected confidence intervals for a smooth curve using local polynomial regression for both the interior and boundary region. We discuss the cases when the degree of the polynomial is odd and even. The uniform confidence intervals are based on the volume-of-tube formula modified for biased estimators. We empirically show that the proposed uniform confidence intervals attain, at least approximately, nominal coverage. Finally, we investigate the performance of the volume-of-tube based confidence intervals for independent non-Gaussian errors.  相似文献

Interpersonal coordination, the extent to which social partners coordinate each other’s postures and mannerisms, acts as a “social glue” that serves both individual and social goals, such as producing prosocial behaviors and facilitating harmonious interactions. Research in this area has become prominent in a variety of domains both within and outside of psychology, forming a sizeable literature dedicated to investigating the causes and consequences of interpersonal coordination. We conducted a series of meta-analyses on studies that treated interpersonal coordination as an independent variable, in order to measure its effect on several intrapersonal (e.g., mood, need to belong) and interpersonal (e.g., prosocial behavior) outcomes, as well as several potential moderators (e.g., percentage of female participants) that may affect the strength of the effect. Overall, the results demonstrated that the positive effects of interpersonal coordination are robust, with a few exceptions specific to intrapersonal outcomes. These findings provide a much-needed quantitative summary of the literature on interpersonal coordination, and highlight areas that merit future research.  相似文献
