工作价值观在付出-回报失衡影响中的调节作用

文中在检验三种付出-回报失衡、工作价值观和过度投入对反生产行为与离职倾向的综合影响.通过层次回归方法着重分析了工作价值观的调节作用,结果验证了工作价值观在付出-回报失衡对反生产行为与离职倾向的影响中有显著的正向调节效应.研究表明为减少员工的反生产行为和离职倾向,结合所能提供的回报,工作价值观是企业在招聘选拔时要考虑的重要因素。     

E-banking in Jordan

The reasons why some customers use e-banking systems whereas others do not is the problem that motivated this study. This study examines the factors underlying customers' technology adoption based on the technology acceptance model (TAM). E-banking adoption is studied from the information systems acceptance point of view; banking customers use the information system to make financial transactions and hence more knowledge of the factors that affect information technology adoption is useful to better understand and facilitate their acceptance. Perceived ease of use, perceived usefulness, subjective norms, security and trust, Internet experience and enjoyment are the important factors that affect customers' adoption of e-banking in Jordan.     

基于云计算的病毒多执行路径

针对目前对于病毒的行为分析工具只能在单机系统中分析一条程序执行的路径,误报率很高的问题,提出了一种行为分析模型。该模型利用云计算海量资源,将病毒多条执行路径的分析移植到云计算虚拟机结点上完成。对每条病毒的执行路径分别在不同的虚拟机结点上并行同时执行分析,通过对虚拟机结点中系统调用的监控找出病毒在某种特定的条件下触发的恶意行为。在开源云平台Eucalyptus的实验表明,该模型可以检测出病毒的条件触发行为,找出触发恶意行为的条件和可以满足这些条件的输入数据,并且性能比单机系统有了很大提升。     

基于扩散分析的网络安全威胁态势评估

针对多数态势评估方法欠缺对授权与依赖关系的考虑、无法反映间接威胁、评估结果对动态防御的指导作用不大的问题,提出了一种以威胁扩散分析为基础、以攻击意图揣测为延伸的评估方法。首先评估了攻击施加的直接威胁,及其沿着依赖关系扩散引发的间接威胁。然后探讨了多攻击并发时的非线性叠加效应。最后使用覆盖法和聚类法揣测攻击意图。实验表明,该方法能更透彻、更精准地揭示安全状况,较好地指导动态防御。     

基于χ~2检验的施工安全监管中行为因素关联分析

水利工程施工中的安全监管错误会引发不安全行为,进一步影响施工人员的工作状态,最终导致事故的发生.基于χ2独立性检验,通过统计学分析提供邻近层次的不同种类之间因素的概率数据,对行为因素之间的独立性进行关联分析,从中找到非独立的因素;确定了人为因素分析与分类系统(HFACS)框架中高层次对底层次因素的影响程度.最后在这些数据的基础上,找到HFACS框架中各因素的作用路径,为防范措施的制定和实施准备工作提供了依据和参考.     

深圳股票市场盈余动量的实证研究

盈余动量现象是投资者对市场非理性反应引起的异象。以1999-2004年深圳股市179家上市公司为样本，检验在2002-2004年期间我国深圳股市是否存在盈余动量现象。构造了零套利投资组合，即买人赢者组合，卖出输者组合，发现持有期3个月以上，都可以获得显著的差额收益，同时验证了行为金融学提出的“反应不足模式”。     

天津地热回灌试验分析及存在问题

在分析天津地区地热地质背景、地热资源赋存条件的基础上,结合地热回灌试验历程及目的,划分了回灌阶段,研究了不同热储层回灌水温度、压力、回灌方式对地层吸水能力的影响和回灌条件下热储层水文地质条件的变化,并对存在问题和发展前景进行了分析和探讨,为下一步工作的开展积累了丰富的资料.研究表明,在天津实施地热回灌开采是可行的,它对延长地热开发寿命、改善生存环境、保持资源的循环利用是非常有效的.     

Performance of Alcohol and Safer Sex Change Rulers Compared With Readiness to Change Questionnaires.

As part of a larger intervention study, the authors hypothesized that change rulers created for alcohol and safer sex would be equivalent to longer questionnaires. Ninety-six male college students completed rulers and questionnaires for assessing behavior change readiness. Participants' scores on the rulers significantly correlated with their scores on the questionnaires (r = .77 for alcohol; r = .77 for safer sex). In both domains, the rulers outperformed the questionnaires in predicting behavioral intentions, suggesting that the rulers had at least comparable concurrent criterion validity. This finding is the first of its kind in the safe sex literature and suggests that quick assessments of readiness to change are possible. Because the rulers are a continuous measure, the results are consistent with the idea that the change process is continuous rather than a series of discrete stages.

The Problem of Measurement Model Misspecification in Behavioral and Organizational Research and Some Recommended Solutions.

The purpose of this study was to review the distinction between formative- and reflective-indicator measurement models, articulate a set of criteria for deciding whether measures are formative or reflective, illustrate some commonly researched constructs that have formative indicators, empirically test the effects of measurement model misspecification using a Monte Carlo simulation, and recommend new scale development procedures for latent constructs with formative indicators. Results of the Monte Carlo simulation indicated that measurement model misspecification can inflate unstandardized structural parameter estimates by as much as 400% or deflate them by as much as 80% and lead to Type I or Type II errors of inference, depending on whether the exogenous or the endogenous latent construct is misspecified. Implications of this research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Increased Vulnerability to Stress Following Opiate Exposures: Behavioral and Autonomic Correlates.

The authors used rats to study the impact of a history of opiate exposures on behavioral and autonomic responses to restraint stress. Brief restraint (30 min) provoked tachycardia and a pressor response, anxiety (as indexed by social interaction), grooming, and reduced exploration. The pressor response was reduced at 1 day, but not 7 days, after last opiate exposure; tachycardia was unaffected (Experiment 1). Stress-induced anxiety was potentiated 1 and 7 days after last opiate exposure (Experiment 2), and this potentiation was a function of dose (Experiment 3) and duration (Experiment 4) of opiate exposure. The results show that a history of opiate exposures alters vulnerability to stress and has implications for understanding coping, anxiety, and emotionality in former opiate users.
