语文课程素养培养模式的探索与建构——以湛江师范学院中文专业为例

语文课程素养是师范院校中文专业人才培养的综合素养,也是人才培养目标的高度浓缩。"课程整合、平台贯通、操作一体化"培养模式,则是针对当下中文专业人才培养中的问题及素养形成规律提出的具体方案。要使这个方案落实到教学中,既需要教师改变课程观念、确定语文课程素养的培养目标,又要通过教学评价进行引导。而这一方案一旦成为教学中的共识,将大大提高师范院校中文专业的人才培养效率和水平。     

Treatment Choice With Trial Data: Statistical Decision Theory Should Supplant Hypothesis Testing

Abstract

A central objective of empirical research on treatment response is to inform treatment choice. Unfortunately, researchers commonly use concepts of statistical inference whose foundations are distant from the problem of treatment choice. It has been particularly common to use hypothesis tests to compare treatments. Wald’s development of statistical decision theory provides a coherent frequentist framework for use of sample data on treatment response to make treatment decisions. A body of recent research applies statistical decision theory to characterize uniformly satisfactory treatment choices, in the sense of maximum loss relative to optimal decisions (also known as maximum regret). This article describes the basic ideas and findings, which provide an appealing practical alternative to use of hypothesis tests. For simplicity, the article focuses on medical treatment with evidence from classical randomized clinical trials. The ideas apply generally, encompassing use of observational data and treatment choice in nonmedical contexts.     

新世纪高校学生干部培养

随着近年来高校招生规模的不断扩大,学生数量急剧增加,一直备受关注的学生管理工作又成为各学校瞩目的焦点,而这一焦点的着力点自然就落到了高校学生干部的培养工作上来。高校学生干部是联系学校、老师和普通学生的桥梁,是学生管理工作中的重要力量,优秀的学生干部能更好的服务于广大学生,因此学生干部的培养尤为重要。目前面对新形势高校学生干部队伍还存在一系列问题与不足,针对这些问题,高校应该加强对学生干部的教育培训、实践锻炼和学习交流,不断健全学生干部培养机制,努力培养一批高素质、高水平、高层次、高能力的高校学生干部队伍。以高校学生干部的培养为立足点,分析新形势下面对学生数量的急剧增加高校培养优秀学生干部的应对策略。     

Schizotypal Personality Disorder: A Clinical Social Work Perspective

Schizotypal personality disorder (SPD) is considered to be a “schizophrenia spectrum disorder” as evidenced in part by its cross-listing in that chapter of the DSM-5. SPD is considered to be a condition with limited potential for positive change because one of its major features is the presence of a biologically based cognitive deficit. This assumption, however, is an example of the medical model’s creating a bias against psychosocial features that are always involved in character development. The social work profession’s bio-psycho-social perspectives focus more comprehensively on all features of the condition and promote a more optimistic view of clients’ change potentials. The purposes of this paper are to examine SPD from a social work perspective and to demonstrate, with a case example, how effective intervention can be organized and delivered.     

乡村教师科研培训课程体系的构建——基于粤西北的调查

调查显示，乡村教师的科研处于初始或停滞状态，亟需构建科研能力培训课程体系。乡村教师缺乏教育教学反思能力是现实中普遍存在的问题，为此要加强对乡村教师教育理论知识的重温与重构。另外，针对乡村教师科研热情不高的现状，要建立科研培训课程体系。一方面，根据教育实践问题为科研活动提供研究方向，设置侧重科研过程原则性和步骤性的培训课程；另一方面，将乡村教师在日常教育教学中生发的心得体会和经验总结转化为科研论文，设置科研论文写作的培训课程。     

Bayes shrinkage estimator for consistency assessment of treatment effects in multi-regional clinical trials

The primary objective of a multi-regional clinical trial is to investigate the overall efficacy of the drug across regions and evaluate the possibility of applying the overall trial result to some specific region. A challenge arises when there is not enough regional sample size. We focus on the problem of evaluating applicability of a drug to a specific region of interest under the criterion of preserving a certain proportion of the overall treatment effect in the region. We propose a variant of James-Stein shrinkage estimator in the empirical Bayes context for the region-specific treatment effect. The estimator has the features of accommodating the between-region variation and finiteness correction of bias. We also propose a truncated version of the proposed shrinkage estimator to further protect risk in the presence of extreme value of regional treatment effect. Based on the proposed estimator, we provide the consistency assessment criterion and sample size calculation for the region of interest. Simulations are conducted to demonstrate the performance of the proposed estimators in comparison with some existing methods. A hypothetical example is presented to illustrate the application of the proposed method.     

The precision of regression-type estimator for incremental cost–effectiveness ratio

The estimation of incremental cost–effectiveness ratio (ICER) has received increasing attention recently. It is expressed in terms of the ratio of the change in costs of a therapeutic intervention to the change in the effects of the intervention. Despite the intuitive interpretation of ICER as an additional cost per additional benefit unit, it is a challenge to estimate the distribution of a ratio of two stochastically dependent distributions. A vast literature regarding the statistical methods of ICER has developed in the past two decades, but none of these methods provide an unbiased estimator. Here, to obtain the unbiased estimator of the cost–effectiveness ratio (CER), the zero intercept of the bivariate normal regression is assumed. In equal sample sizes, the Iman–Conover algorithm is applied to construct the desired variance–covariance matrix of two random bivariate samples, and the estimation then follows the same approach as CER to obtain the unbiased estimator of ICER. The bootstrapping method with the Iman–Conover algorithm is employed for unequal sample sizes. Simulation experiments are conducted to evaluate the proposed method. The regression-type estimator performs overwhelmingly better than the sample mean estimator in terms of mean squared error in all cases.

Generalizing the standardized hazard ratio to multivariate proportional hazards regression,with an application to clinical~genomic studies

The standardized hazard ratio for univariate proportional hazards regression is generalized as a scalar to multivariate proportional hazards regression. Estimators of the standardized log hazard ratio are developed, with corrections for bias and for regression to the mean in high-dimensional analyses. Tests of point and interval null hypotheses and confidence intervals are constructed. Cohort sampling study designs, commonly used in prospective–retrospective clinical genomic studies, are accommodated.
