Developing civic consciousness through social engagement among Hong Kong youths

It is not clear how much young people's engagement in activities in the school, youth center, family, and mass media influence their civic consciousness. To answer this question, the present study conducted 7,649 telephone interviews to collect data from 3,757 Chinese young people in Hong Kong repeatedly from 1998 to 2000. The panel study, by controlling for prior scores, allowed for examination of changes due to various forms of social engagement. Results show that in this naturally occurring setting, participation in social development activities, such as volunteering, community service, and leadership training, contributed to the average young person's civic consciousness about democracy and leadership whereas discussion with family members contributed significantly to the person's consciousness about societal progress. These results endorse the greater developmental role of the school and family than the youth center.     

Order statistics from extreme value distribution,ii: best linear unbiased estimates and some other uses

Let Y_r+1:n ≤ _Y:r+2:n ≤≤… <Y_n?6:n-<: TYPE-II censored sample from an extreme value population with µ and α as the location and scale parameters, respectively. Tables of coefficients for the best linear unbiased estimators (BLUEs) of µ and α are presented for various choices of censoring and sample sizes n = 2(1)15(5)30; variances and covariance of these estimators are also presented. The computational formulae and procedure used and some checks employed are explained. We finally illustrate some uses of the tables by taking examples.     

A Note on Criterion-Robust Optimal Designs for Model Discrimination and Parameter Estimation in Polynomial Regression Models

Consider the problem of discriminating between the polynomial regression models on [?1, 1] and estimating parameters in the models. Zen and Tsai (2002 Zen , M. M. , Tsai , M. H. ( 2002 ). Some criterion-robust optimal designs for the dual problem of model discrimination and parameter estimation . Sankhya Ind. J. Statist. 64 : (Series B, Pt. 3) : 322 – 338 . [Google Scholar]) proposed a multiple-objective optimality criterion, M _γ-criterion, which uses weight γ (0 ≤ γ ≤ 1) for model discrimination and α = β = (1 ? γ)/2 for parameter estimation in each model. In this article, we generalize it to a wider setup with different values of α and β. For instance, α = 2 β suggests that the “smaller” model is more likely to be the true model. Using similar techniques, the corresponding criterion-robust optimal design is investigated. A study for the original criterion-robust optimal design with α = β, through M-efficiency, shows that it is good enough for any wider setup.     

Estimating Transition Probabilities for Ignorable Intermittent Missing Data in a Discrete-Time Markov Chain

This article considers a discrete-time Markov chain for modeling transition probabilities when multiple successive observations are missing at random between two observed outcomes using three methods: a na\"?ve analog of complete-case analysis using the observed one-step transitions alone, a non data-augmentation method (NL) by solving nonlinear equations, and a data-augmentation method, the Expectation-Maximization (EM) algorithm. The explicit form of the conditional log-likelihood given the observed information as required by the E step is provided, and the iterative formula in the M step is expressed in a closed form. An empirical study was performed to examine the accuracy and precision of the estimates obtained in the three methods under ignorable missing mechanisms of missing completely at random and missing at random. A dataset from the mental health arena was used for illustration. It was found that both data-augmentation and nonaugmentation methods provide accurate and precise point estimation, and that the na\"?ve method resulted in estimates of the transition probabilities with similar bias but larger MSE. The NL method and the EM algorithm in general provide similar results whereas the latter provides conditional expected row margins leading to smaller standard errors.     

C市T区人民检察院适用刑事和解调研报告

在构建和谐社会与贯彻宽严相济刑事政策的背景下,各地检察机关积极探索在公诉案件中鼓励当事人和解的宽缓处理方式,取得了积极的社会效果。但由于受现行法律制度、司法资源以及传统观念的束缚,对适用和解程序处理刑事案件在案件范围、处理方式及相关配套措施等方面还存在一些问题,实践中人民检察院也有较大的顾虑,适用刑事和解的积极性不高。针对这些问题,应该从立法的层面确立刑事和解制度,明确刑事和解案件的赔偿标准,建立加害人帮教机制。     

考虑公平关切的供应链契约与协调

供应链契约是影响供应链整体绩效的重要因素.在传统两阶段供应链中引入公平关切,研究了公平关切行为倾向对供应链契约与协调的影响.文中假设零售商是公平关切的,在此假设下展开行为运筹分析,分别探讨了零售商的公平关切行为倾向对批发价契约,收益共享契约和回购契约等协调性的影响,并用算例加以验证.最后,在此基础上提出并证明了一般性结论:零售商的公平关切不会改变供应链的协调状态.     

Supplier integration and firm performance: the moderating effects of internal integration and trust

This study proposes and empirically tests a model of the moderating effects of internal integration and trust on the impacts of information, process and strategic integration with suppliers on firm performance using structural equation modelling and data collected from 261 manufacturing firms in Vietnam. The results show that all three types of supplier integration positively associate with firm performance. Internal integration enhances the impact of process integration with suppliers on firm performance, but does not moderate the impacts of information and strategic integration with suppliers. Internal trust has insignificant, positive and negative influences on the effects of information, process and strategic integration with suppliers on firm performance. The findings show that internal integration and trust play different roles in moderating the positive effects of information, process and strategic integration with suppliers on firm performance, which elucidates a possible reason for previous mixed findings on the relationship between supplier integration and firm performance.     

Caseworkers as a source of hope leading to perceptions of academic success for transitional age foster youth

Research among adolescent samples has consistently demonstrated that a hopeful mindset is associated with resilience and global well-being. Further, research suggests that hope is influenced from an early age from connections with supportive caregivers. However, because older youth in the child welfare system may lack supportive caregivers, alternative sources of hope may be needed. To test a theory that supportive child welfare caseworkers can serve as external sources of hope, we conducted a cross-sectional study of youth in the child welfare system from a single state (N = 149). Using surveys with established scales to measure the variables of interest, the study tested a structural equation model of (1) youth's external hope in their caseworker as a driver of (2) internal hope in themselves leading to (3) more positive perceptions of academic success. Perceptions of academic success were chosen as the final consequence of the model because academic success has been linked to many other variables of well-being across the lifespan. The results indicate that the proposed structural model fits the data well (χ² = 327.9, df = 150; P < 0.001; root-mean-square error of approximation [RMSEA] = 0.09 [90% confidence interval – CI: 0.076, 0.103]; comparative fit index [CFI]: 0.920; standardized root-mean-square residual [SRMR]: 0.05). The results indicate that youths' hope in themselves had origins in external hope in the caseworker. Moreover, the final consequence was an increase in perceptions of academic success. Such results have implications by revealing how case management services can positively influence foster youths' hope and thereby influence their academic success.
