We examined whether exposing women to female models with different body sizes lead to changes in weight-based attitudes and whether evaluation focus altered the effects. Female college students (N = 214) were exposed to 22 images of either thin or overweight models. Participants rated models on either appearance or non-appearance characteristics and completed measures of anti-fat attitudes, thin ideal internalization, and demographics. Participants rated thin and overweight models equally attractive and sexy. Viewing overweight models showed a significant reduction in anti-fat attitudes. There were no effects for thin models or evaluation ratings. Discussion focuses on the implications of positive images of overweight individuals on social attitudes. 相似文献

This paper discusses regression analysis of clustered current status data under semiparametric additive hazards models. In particular, we consider the situation when cluster sizes can be informative about correlated failure times from the same cluster. To address the problem, we present estimating equation-based estimation procedures and establish asymptotic properties of the resulting estimates. Finite sample performance of the proposed method is assessed through an extensive simulation study, which indicates the procedure works well. The method is applied to a motivating data set from a lung tumorigenicity study. 相似文献

Despite policy efforts to increase adolescent happiness, their impact has been unsatisfactory. Their limited impact may be rooted from a discrepancy between values that adolescents pursued and those that the policies were based on. To provide policy implications, our study aims to identify prevailing values for South Korean, Japanese, and Chinese adolescents and to examine the relationship between the values and self-rated happiness (SRH). A cross-sectional study was conducted using survey data collected on approximately 2000 middle and high school students (7th to 12th school grade) from each country in 2008. Firstly, an explanatory factor analysis was conducted to identify salient adolescent values from each country. Subsequently, a multiple logistic regression analysis was conducted for each population group to examine the relationship between the identified values and adolescent SRH after controlling for sociodemographic characteristics. We found that benevolence and altruism were positively associated with adolescent SRH in all three population groups. Patriarchy was associated with SRH positively in Chinese yet inversely in Japanese. Success pursuit was inversely associated with SRH in Korean. Policy efforts based on values of communities or social harmony may benefit adolescents’ SRH in these three countries. 相似文献

A randomized trial allows estimation of the causal effect of an intervention compared to a control in the overall population and in subpopulations defined by baseline characteristics. Often, however, clinical questions also arise regarding the treatment effect in subpopulations of patients, which would experience clinical or disease related events post-randomization. Events that occur after treatment initiation and potentially affect the interpretation or the existence of the measurements are called intercurrent events in the ICH E9(R1) guideline. If the intercurrent event is a consequence of treatment, randomization alone is no longer sufficient to meaningfully estimate the treatment effect. Analyses comparing the subgroups of patients without the intercurrent events for intervention and control will not estimate a causal effect. This is well known, but post-hoc analyses of this kind are commonly performed in drug development. An alternative approach is the principal stratum strategy, which classifies subjects according to their potential occurrence of an intercurrent event on both study arms. We illustrate with examples that questions formulated through principal strata occur naturally in drug development and argue that approaching these questions with the ICH E9(R1) estimand framework has the potential to lead to more transparent assumptions as well as more adequate analyses and conclusions. In addition, we provide an overview of assumptions required for estimation of effects in principal strata. Most of these assumptions are unverifiable and should hence be based on solid scientific understanding. Sensitivity analyses are needed to assess robustness of conclusions. 相似文献

当前我国人民陪审员制度改革的核心是将人民陪审员"法律内行、同职同权"的角色期望纠正为"法律外行、异职异权",将人民陪审员"消极参与"与"过于积极参与"并存的角色认知纠正为"民主的参与者,事实真相的发现者和社会价值的代言者",以推动人民陪审员制度充分发挥促进司法民主、司法公正和司法公信的功能.在人民陪审员制度改革基本框架已确立的前提下,应通过完善配套制度建设将改革的基本前提预设转化为正当的司法运作秩序,保证当前人民陪审员制度改革生根发芽.这些制度主要包括两种类型:事实领域的人民陪审员知晓争议焦点规范与人民陪审员一事一证规范,意见效力领域的合议庭评议规范和审委会及二审法院复审规范. 相似文献

政府与市场的关系问题是经济法规制的基于问题,如何正确看待政府与市场在经济生态系统内各自的功能及作用,是经济法规制的核心问题。因为这样的认识直接导致了经济立法的体系构建与内容规则。经济法规制是国家实施经济治理与尊重市场调节的基本依据,也是施行经济法治与社会治理的根本前提。所以,从社会治理的背景下来讨论经济法规制的社会经济发展的制度条件及制度生成条件,有利于真正建立和完善经济法规制的体系和内容,从而使得经济法治生态化地融入社会治理的结构体系内,达到优化社会制度以促进经济发展的目的。 相似文献
