Experimental Tests of the Prediction that Inequality Increases System Justification Motivation Trump, Kris-Stella; White, Ariel R. Past research shows that growing inequality often does not result in citizen demands for redistribution. We examine one mechanism that could explain why people do not protest growing inequality: a particular sub-prediction of system justification theory (SJT). SJT argues that humans have a psychological need to justify their social system. The specific sub-prediction of SJT tested here is the idea that inequality itself increases system justification. This could yield a negative feedback loop in which political responses to inequality grows ever less likely as inequality grows more extreme. Previous research on this hypothesis relied on cross-sectional survey data and provided mixed results. We take an experimental approach and ask whether exposure to economic inequality makes people more likely to defend the system. In one main study and two replications with varying samples, experimental treatments, and outcome measures, we find no evidence that information about economic inequality increases system justification motivation. 2018-01-01T00:00:00Z The symmetry energy γ parameter of relativistic mean-field models Dutra, Mariana Louren?o, Odilon Hen, Or Piasetzky, Eliezer Menezes, Débora P. https://hdl.handle.net/1721.1/128559 2020-11-21T03:14:49Z 2018-05-01T00:00:00Z The symmetry energy γ parameter of relativistic mean-field models Dutra, Mariana; Louren?o, Odilon; Hen, Or; Piasetzky, Eliezer; Menezes, Débora P. The relativistic mean-field models tested in previous works against nuclear matter experimental values, critical parameters and macroscopic stellar properties are revisited and used in the evaluation of the symmetry energy γ parameter obtained in three different ways. We have checked that, independent of the choice made to calculate the γ values, a trend of linear correlation is observed between γ and the symmetry energy () and a more clear linear relationship is established between γ and the slope of the symmetry energy (L 0). These results directly contribute to the arising of other linear correlations between γ and the neutron star radii of and , in agreement with recent findings. Finally, we have found that short-range correlations induce two specific parametrizations, namely, IU-FSU and DD-MEδ, simultaneously compatible with the neutron star mass constraint of and with the overlap band for the region, to present γ in the range of. ?2018 Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academy of Sciences and the Institute of Modern Physics of the Chinese Academy of Sciences and IOP Publishing Ltd. 2018-05-01T00:00:00Z The Promises and Pitfalls of 311 Data White, Ariel R.

It seems a promising measure of neighborhood political participation. However, these data are empirically and theoretically different from many common citizen-level participation measures. We compare geographically aggregated 311 call data with three other measures of political and civic participation: voter turnout, political donations, and census return rates. We show that rates of 311 calls are negatively related to lower cost activities (voter turnout and census return rates), but positively related to the high-cost activity of campaign donation. We caution against interpreting 311 data as a generic measure of political engagement or participation, at least in the absence of high-quality controls for neighborhood condition. However, we argue that these data are still potentially useful for researchers, because they are by definition a measure of the service demands that neighborhoods place on city governments. 2016-11-01T00:00:00Z Efficacy and Effectiveness Too Trials: Clinical Trial Designs to Generate Evidence on Efficacy and on Effectiveness in Wide Practice Selker, Harry P.

Efficacy trials, designed to gain regulatory marketing approval, evaluate drugs in optimally selected patients under advantageous conditions for relatively short time periods. Effectiveness trials, designed to evaluate use in usual practice, assess treatments among more typical patients in real-world conditions with longer follow-up periods. In “efficacy-to-effectiveness (E2E) trials,” if the initial efficacy trial component is positive, the trial seamlessly transitions to an effectiveness trial component to efficiently yield both types of evidence. Yet more time could be saved by simultaneously addressing efficacy and effectiveness in an “efficacy and effectiveness too (EE2) trial.” Additionally, hybrids of the E2E and EE2 approaches with differing degrees of overlap of the two components could allow flexibility for specific drug development needs. In planning EE2 trials, each stakeholder's current and future needs, incentives, and perspective must be considered. Although challenging, the ultimate benefits to stakeholders, the health system, and the public should justify this effort. 2019-02-01T00:00:00Z 狠狠躁天天躁中文字幕_日韩欧美亚洲综合久久_漂亮人妻被中出中文字幕
