新形势下高校保密工作问题与对策

作为国家行政事业单位的重要组成部分,高校是产生、存储和使用国家秘密较为集中的单位。随着教学科研的深入发展,高校涉密事项日益增多,高校保密工作的重要性逐渐受到人们的关注。做好高校保密工作,关系着学校的稳定与发展。当前高校保密工作面临着诸多问题,需要我们进行深入的思考,采取有效的措施积极应对。     

Estimation of multivariate conditional-tail-expectation using Kendall's process

This paper deals with the problem of estimating the multivariate version of the Conditional-Tail-Expectation, proposed by Di Bernardino et al. [(2013), ‘Plug-in Estimation of Level Sets in a Non-Compact Setting with Applications in Multivariable Risk Theory’, ESAIM: Probability and Statistics, (17), 236–256]. We propose a new nonparametric estimator for this multivariate risk-measure, which is essentially based on Kendall's process [Genest and Rivest, (1993), ‘Statistical Inference Procedures for Bivariate Archimedean Copulas’, Journal of American Statistical Association, 88(423), 1034–1043]. Using the central limit theorem for Kendall's process, proved by Barbe et al. [(1996), ‘On Kendall's Process’, Journal of Multivariate Analysis, 58(2), 197–229], we provide a functional central limit theorem for our estimator. We illustrate the practical properties of our nonparametric estimator on simulations and on two real test cases. We also propose a comparison study with the level sets-based estimator introduced in Di Bernardino et al. [(2013), ‘Plug-In Estimation of Level Sets in A Non-Compact Setting with Applications in Multivariable Risk Theory’, ESAIM: Probability and Statistics, (17), 236–256] and with (semi-)parametric approaches.     

Examining the effects of gambling-relevant cues on gambling outcome expectancies

There is a consensus in the addictions literature that exposure to addiction-relevant cues can precipitate a desire to engage, or actual engagement, in the addictive behaviour. Previous work has shown that exposure to gambling-relevant cues activates gamblers’ positive gambling outcome expectancies (i.e. their beliefs about the positive results of gambling). The current study examined the effects of a new, arguably more ecologically valid cue manipulation (i.e. exposure to a gambling lab environment vs. sterile lab environment) on 61 regular gamblers’ explicit and implicit gambling outcome expectancies. The authors first tested the internal consistency of their implicit reaction time measure of gambling outcome expectancies, the Affective Priming Task. Split-half reliabilities were satisfactory to high (.72 to .88), highlighting an advantage of this task over other characteristically unreliable implicit cognitive measures. Unexpectedly, no predicted between-lab condition differences emerged on most measures of interest, suggesting that peripheral environmental cues that are not the focus of deliberate attentional allocation may not activate positive outcome expectancies. However, there was some evidence that implicit negative gambling outcome expectancies were activated in the gambling lab environment. This latter finding holds clinical relevance as it suggests that presenting peripheral gambling-related cues while treating problem gamblers may facilitate processing of the negative consequences of gambling.     

小学课堂教学中情感教育现状与实施对策研究

目前我国小学课堂教学中普遍存在着“情感教育缺失”的现象。情感教育缺失严重影响小学生身心发展。本文列举了情感教育缺失的现状表现，包括：忽视学习内容的情感教育价值;知情教育不统一，情感教育形同虚设;忽略课堂创生的情感教育素材等，并提出情感教育的实施对策，包括：更新教育理念，践行三维目标体系;加强小学教师教育培训;发挥小学生的主体地位，教育面向全体小学生;适度渲染情感教育素材，鼓励学生情感的合理表达;广泛应用多元情感教育方式等。希望为小学教师实施情感教育提供一些具体可行的对策方法，促进小学生的情感发展。     

对“行政强制措施”识别标准的反思:以道路交通领域为观察对象

《行政强制法》颁布后,学界普遍认为识别行政强制措施在于其是否具有强制性与临时性特点,但实务部门运用这一标准识别行政强制措施时却出现了认定困难的局面,因为在《行政强制法》颁布前,各种层次的法律、规范性文件就已经对道路交通行政强制强制进行了规定,因此识别标准必须面对法条的复杂性。部分道路交通行政强制措施不能从法条上判断其是否具有强制性与临时性,需要结合实践与行为目的去判断。     

Distributional equality in non-classical utilitarianism — A proof of Lerner's theorem for ‘utilitarianism incorporating justice’

The paper initially proposes a non-classical utilitarian aggregation function which is accomplished by suitably weaving around the classical utilitarian function a group of parameters of justice (including desert factors and a sublinear measure of inequality which mathematically favours more equal distribution of utility levels). Then the Lerner-theorem for classical utilitarianism is first proved in a way which differs from each of the earlier proofs presented for this theorem and in the core of the paper also extended to this new non-classical version of utilitarianism.     

Statistical issues in epidemiologic studies of the health effects of ambient acid aerosols

Although the ecologic effects of acid rain have been widely reported, relatively little is known about the effects of acidic air pollution on human health. Some epidemiologic and animal studies suggest, however, that acidity is an important determinant of the respiratory health effects of aerosols. This paper reviews some of that evidence and discusses its implications for the design and analysis of epidemiologic studies. We contrast two types of exposure patterns: peak exposures associated with air pollution episodes, and chronic exposures resulting from persistently high levels of air pollutants. Recent work on the analysis of repeated categorical outcome variables provides new methods for the analysis of episode studies. Studies of long-term exposure require comparisons among population groups, and these comparisons can be subject to the design effects characteristic of multistage sample surveys. We examine the implications of these design effects for epidemiologic studies. Finally, the paper discusses the measurement errors induced by the use of outdoor measurements to quantify personal exposure to air pollutants. Recent work on methods for errors-in-variables problems may aid in assessing the effects of such errors on conventional analyses of air-pollution studies.
