Concepts of power and agency have become increasingly prominent in the youth studies literatures and related research. A focus of the research to date has been an examination of how a better understanding of young people's lived experiences can reveal possibilities for young people's agency to emerge. Despite increased interest in the term agency, much less has been said about how the concept is defined and recognized in research with young people, including what the concept may entail but crucially, how the term is linked to and underpinned by the related concept of power. This paper seeks to contribute to our understanding of power and agency as utilized in research with young people. The discussion that follows identifies the possible ways in which different theoretical positions shape our understanding of how power and agency are investigated and how these understandings inform the ways we interpret young people's perspectives and actions as holding potential for ‘agency’. Drawing on recent empirical examples, we consider how varying interpretations of power and/or agency shape not only the ways in which young people's agentic experiences are theorized (and the related ontological and epistemological assumptions these positions imply) but also the presumed effects of that agency. 相似文献

In this paper, multivariate two-sample testing problems were examined based on the Jure?ková–Kalina's ranks of distances. The multivariate two-sample rank test based on the modified Baumgartner statistic for the two-sided alternative was proposed. The proposed statistic was a randomized statistic. Simulations were used to investigate the power of the suggested statistic for various population distributions. 相似文献

To adjust or not to adjust for baseline when analyzing repeated binary responses? The case of complete data when treatment comparison at study end is of interest 下载免费PDF全文

The benefits of adjusting for baseline covariates are not as straightforward with repeated binary responses as with continuous response variables. Therefore, in this study, we compared different methods for analyzing repeated binary data through simulations when the outcome at the study endpoint is of interest. Methods compared included chi‐square, Fisher's exact test, covariate adjusted/unadjusted logistic regression (Adj.logit/Unadj.logit), covariate adjusted/unadjusted generalized estimating equations (Adj.GEE/Unadj.GEE), covariate adjusted/unadjusted generalized linear mixed model (Adj.GLMM/Unadj.GLMM). All these methods preserved the type I error close to the nominal level. Covariate adjusted methods improved power compared with the unadjusted methods because of the increased treatment effect estimates, especially when the correlation between the baseline and outcome was strong, even though there was an apparent increase in standard errors. Results of the Chi‐squared test were identical to those for the unadjusted logistic regression. Fisher's exact test was the most conservative test regarding the type I error rate and also with the lowest power. Without missing data, there was no gain in using a repeated measures approach over a simple logistic regression at the final time point. Analysis of results from five phase III diabetes trials of the same compound was consistent with the simulation findings. Therefore, covariate adjusted analysis is recommended for repeated binary data when the study endpoint is of interest. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Exact calculation of power and sample size in bioequivalence studies using two one‐sided tests 下载免费PDF全文
The number of subjects in a pharmacokinetic two‐period two‐treatment crossover bioequivalence study is typically small, most often less than 60. The most common approach to testing for bioequivalence is the two one‐sided tests procedure. No explicit mathematical formula for the power function in the context of the two one‐sided tests procedure exists in the statistical literature, although the exact power based on Owen's special case of bivariate noncentral t‐distribution has been tabulated and graphed. Several approximations have previously been published for the probability of rejection in the two one‐sided tests procedure for crossover bioequivalence studies. These approximations and associated sample size formulas are reviewed in this article and compared for various parameter combinations with exact power formulas derived here, which are computed analytically as univariate integrals and which have been validated by Monte Carlo simulations. The exact formulas for power and sample size are shown to improve markedly in realistic parameter settings over the previous approximations. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

非法证据排除的权利效能是辩方排除非法证据的实际效果与法律授予的理想权利之间的比值。非法证据排除规则赋予了辩方较大的权利,并随着诉讼进程而增强。但实际所取得的效益却是逐程减弱,并最终在庭审阶段降至权利效能的最低点。这种尴尬局面是由法律、制度以及辩护策略等原因造成。从诉讼结构出发去研究权利效能,对于完善该制度具有功能意义,应从保证控辩双方效能值的全程一致、限制法官自由裁量权与完善辩方权利行使机制三个方面着手构建。 相似文献

In this article, we consider some nonparametric goodness-of-fit tests for right censored samples, viz., the modified Kolmogorov, Cramer–von Mises–Smirnov, Anderson–Darling, and Nikulin–Rao–Robson χ2 tests. We also consider an approach based on a transformation of the original censored sample to a complete one and the subsequent application of classical goodness-of-fit tests to the pseudo-complete sample. We then compare these tests in terms of power in the case of Type II censored data along with the power of the Neyman–Pearson test, and draw some conclusions. Finally, we present an illustrative example. 相似文献
