校园暴力的成因分析及预防策略探究   总被引:4,自引:0,他引:4  
校园暴力看似一种个别的、简单的社会现象,其实却具有复杂的社会心理背景,它是家庭结构或功能不健全、学校管理理念落后、教师管教失当、接受大众传媒负面影响、结交不良同伴等相互作用的混合产物.对校园暴力的预防应充分运用政府、社会、学校、家庭等各方面的资源,职责明确、责任到位,形成校园暴力治理的合力,才能为青少年学生全面和谐发展提供良好的条件.  相似文献

我国学校教研组从表面看,是借鉴俄国先例建立的,其实是我国特殊历史条件的产物。它不是单纯的教学研究组织,还是学校基层行政组织。它越来越名不副实,对学校教学与教师发展,既有一定积极作用,也有不可忽视的消极影响。  相似文献

Consider a randomized trial in which time to the occurrence of a particular disease, say pneumocystis pneumonia in an AIDS trial or breast cancer in a mammographic screening trial, is the failure time of primary interest. Suppose that time to disease is subject to informative censoring by the minimum of time to death, loss to and end of follow-up. In such a trial, the censoring time is observed for all study subjects, including failures. In the presence of informative censoring, it is not possible to consistently estimate the effect of treatment on time to disease without imposing additional non-identifiable assumptions. The goals of this paper are to specify two non-identifiable assumptions that allow one to test for and estimate an effect of treatment on time to disease in the presence of informative censoring. In a companion paper (Robins, 1995), we provide consistent and reasonably efficient semiparametric estimators for the treatment effect under these assumptions. In this paper we largely restrict attention to testing. We propose tests that, like standard weighted-log-rank tests, are asymptotically distribution-free -level tests under the null hypothesis of no causal effect of treatment on time to disease whenever the censoring and failure distributions are conditionally independent given treatment arm. However, our tests remain asymptotically distribution-free -level tests in the presence of informative censoring provided either of our assumptions are true. In contrast, a weighted log-rank test will be an -level test in the presence of informative censoring only if (1) one of our two non-identifiable assumptions hold, and (2) the distribution of time to censoring is the same in the two treatment arms. We also extend our methods to studies of the effect of a treatment on the evolution over time of the mean of a repeated measures outcome, such as CD-4 count.  相似文献

A Multivariate Model for Repeated Failure Time Measurements   总被引:1,自引:1,他引:0  
A parametric multivariate failure time distribution is derived from a frailty-type model with a particular frailty distribution. It covers as special cases certain distributions which have been used for multivariate survival data in recent years. Some properties of the distribution are derived: its marginal and conditional distributions lie within the parametric family, and association between the component variates can be positive or, to a limited extent, negative. The simple closed form of the survivor function is useful for right-censored data, as occur commonly in survival analysis, and for calculating uniform residuals. Also featured is the distribution of ratios of paired failure times. The model is applied to data from the literature  相似文献

A central part of probabilistic public health risk assessment is the selection of probability distributions for the uncertain input variables. In this paper, we apply the first-order reliability method (FORM)(1–3) as a probabilistic tool to assess the effect of probability distributions of the input random variables on the probability that risk exceeds a threshold level (termed the probability of failure) and on the relevant probabilistic sensitivities. The analysis was applied to a case study given by Thompson et al. (4) on cancer risk caused by the ingestion of benzene contaminated soil. Normal, lognormal, and uniform distributions were used in the analysis. The results show that the selection of a probability distribution function for the uncertain variables in this case study had a moderate impact on the probability that values would fall above a given threshold risk when the threshold risk is at the 50th percentile of the original distribution given by Thompson et al. (4) The impact was much greater when the threshold risk level was at the 95th percentile. The impact on uncertainty sensitivity, however, showed a reversed trend, where the impact was more appreciable for the 50th percentile of the original distribution of risk given by Thompson et al. 4 than for the 95th percentile. Nevertheless, the choice of distribution shape did not alter the order of probabilistic sensitivity of the basic uncertain variables.  相似文献

对行政强制措施实行检察监督是十八届四中全会赋予检察机关的改革任务。在全面依法治国和监察体制改革背景下,检察机关履行行政强制措施检察监督职能既有必要性,也有可行性。在下一步检察改革过程中,应当坚持有限监督、适时监督、行政先行救济原则,探索采用检察建议、支持起诉、督促纠正违法、提请责任追究等方式对违法行政强制措施进行监督。  相似文献

在习近平新时代中国特色社会主义教育思想和创新驱动机制的牵引下,强化教育管理和提高教学质量已成为高等教育发展和改革的核心主题,而积极探究和试行大学研究性学习模式是新时代教育改革及人才培养方式的一种发展趋势。为实现大学研究性学习模式的可持续发展与创新,应从教育管理的本质出发,将其作为联系学校教育各参与方的纽带,坚持对行政管理理念、教师管理体制以及学生管理制度等三个方面进行革故鼎新,为大学研究性学习的生存与发展提供植根土壤。  相似文献

“司法审查有限原则”是行政诉讼法的基本原则,这导致了“履行法定职责实体判决”存在争议。“尹荷玲案”不但证成了履行法定职责实体判决存在的正当性,而且明确了该判决适用的“双阶要件”,即“理由具备、事实清楚、法律规定明确”的一般要件,与“法效果唯一性”的特别要件。其中“法效果唯一性”分为两种情况:一是羁束行政行为,二是行政裁量收缩为零,这恰与《行政诉讼法》修改后“给付判决”与“履行判决”的规定相契合。纵观司法实践,重做判决、履行判决、给付判决形成了“程序性判决—提示性判决—履行法定职责实体判决”3种判决方式,体现了三者功能的相似性。作为实质化解争议的履行法定职责实体判决,也彰显了司法推动制度发展的功能。  相似文献

Having demonstrated its credentials as one of the more elegant and robust conceptualisations of human relationships, attachment theory has considerable relevance to social work. Attachment‐based research has flourished over the past few years and it now includes an impressive array of studies across the lifespan. This article considers four different measures used in attachment‐based research, although more discussion is devoted to interview and projective measures because they specifically embrace a psychodynamic approach in their design and analytic focus. The aim of the article is to provide a brief overview of each measure and to offer some illustrative examples using practice‐related material.  相似文献

非法证据排除规则最早在美国确立并得到发展,形成一套比较完整的体系。我国对非法证据排除规则的探讨很长时期仅停留在理论阶段,2012年《刑事诉讼法》修改中采纳并确立这一证据规则,使其从理论探讨变为实践,也为行政诉讼非法证据排除规则的探讨提供了很好的借鉴。目前,行政诉讼法正处于修改时期,以现有的法律规范为基础探讨行政诉讼非法证据的类型及其判断标准显得尤为必要。  相似文献
