论取消庭审退回补充侦查制度

庭审退回补充侦查制度虽有可能使一些案件查明事实真相,但它与刑事诉讼法的其他制度和一些审判规律的矛盾,以及由此带来的消极影响也是显而易见的。为了消除不必要的制度内耗,使诉讼制度更为合理,取消庭审退回补充侦查制度是一个明智的选择。     

论民事纠纷解决机制之重构

受当前制度设计的制约,我国民事诉讼中存在纠纷解决效率低下和渠道单一的问题,因此,强化第一审的作用,改革简易程序和将法院调解变革为法院附设ADR就显得非常必要。文章试对此予以探讨,揭示现行解决纠纷机制存在的弊端,以期能对立法和司法提供借鉴。     

对我国民事审级制度的思考

伴随经济的发展、时代的变迁，我国民事审级制度近几年面临严重危机，存在着诸多缺陷，主要表现在：四级法院分工不明，导致各审级功能混淆；两审终审制过于僵化，导致诉讼成本加大；再审程序与两审终审制存在冲突。针对这些缺陷，提出几点建设性意见。

An implementation and outcome evaluation of a multicomponent sexuality education programme for high school students

Numerous classroom-based interventions have aimed to improve sexual health outcomes for young people, yet few have shown strong, lasting effects. Ecological approaches that address multiple levels of a young person’s environment offer largely untapped potential to positively change sexual behaviour. This paper presents results of a cluster-randomised trial of a multicomponent sexuality education intervention that integrated a classroom curriculum, parent education workshops and materials, peer advocate programme, and sexual health services at 10 urban high schools. An implementation evaluation, employing quantitative and qualitative instruments, was conducted to examine whether the individual components of the intervention were delivered as planned and how they were received by the target populations. Multilevel modelling was used to evaluate the effect of the multicomponent intervention on outcomes at one-year follow-up. Results showed that the intervention components were successfully implemented with and well received by target populations. Students receiving the multicomponent intervention reported greater increases in the use of sexual health services (odds ratio [OR] = 1.73, 95% CI = 1.09–2.75) and the likelihood of carrying a condom (OR = 2.71, 95% CI = 1.44–5.09) relative to those receiving a control condition. No effects were found for other behaviours, possibly due to low prevalence of sexual activity in the sample and the small number of schools randomised.     

Effects of problem-based discussion on studying a subsequent text: A randomized trial among first year medical students

The Purpose of this study was to examine effectsof group discussion of a medical problem on the comprehension of a subsequentproblem-relevant text by first year medical students.Forty-eight first-year medical students were randomly assigned toone of two conditions: The experimental group discussed a problem of blood pressureregulation, where the control group discussed a problem of vision. Subsequently, allstudents studied a text on the physiology of blood pressure regulation. Finally, a freerecall test was administered. Numbers of propositions accurately recalled were analyzed usinganalysis of variance (ANOVA). Students who discussed the blood pressure regulationproblem recalled 25% more from the text than those who discussed the control problem.This difference was statistically significant. The present study represented thefirst truly randomized trial in the ecologically valid context of a medical curriculum. Itdemonstrated the positive effects of problem-based tutorial group discussion on thecomprehension of text. It confirmed earlier findings from laboratory studies thatproblem-based learning, in addition to positive emotional and motivational long-term effectswell-documented in the literature, also has positive effects on learning.     

PUBLICATION BIAS: THE ACHILLES' HEEL OF SYSTEMATIC REVIEWS?

ABSTRACT:  The term 'publication bias' usually refers to the tendency for a greater proportion of statistically significant positive results of experiments to be published and, conversely, a greater proportion of statistically significant negative or null results not to be published. It is widely accepted in the fields of healthcare and psychological research to be a major threat to the validity of systematic reviews and meta-analyses. Some methodological work has previously been undertaken, by the author and others, in the field of educational research to investigate the extent of the problem. This paper describes the problem of publication bias with reference to its history in a number of fields, with special reference to the area of educational research. Informal methods for detecting publication bias in systematic reviews and meta-analyses of controlled trials are outlined and retrospective and prospective methods for dealing with the problem are suggested.
