2岁儿童社会性行为发展及其与家庭因素的关系研究

采用陌生情境法等实验方法对52名2岁儿童社会性行为进行研究,同时对其父母用问卷了解儿童问题行为和各种家庭因素资料。研究结果显示我国2岁儿童：（1）安全型依恋比例较高,A型依恋无回避行为;（2）抗挫折和抗诱惑行为较差;（3）安全型依恋问题行为较少,非安全型依恋问题行为较多;（4）各行为间有显著相关;（5）儿童社会性行为与家庭背景、夫妻关系无显著相关,与家庭氛围,亲子关系及父母教养观念有显著相关。     

Effect on tipping of barman drawing a sun on the bottom of customers' checks

Previous research has demonstrated that a pleasant drawing (a smiling face) on a restaurant bill increased the number of tips left by clients. A similar experiment was carried out using a drawing of the sun since it is known that tips increase on sunny days. The experiment was carried out in local bars and involved clients who have ordered an espresso coffee. Analysis showed that the drawing of the sun led clients to leave a tip more frequently than when this drawing is not present. The size of the tip left was also higher. The hypothesis of the creation of a positive frame of mind by this stimulus is discussed.     

Vergleiche zwischen sozialtherapeutischen Einrichtungen

The penal system and treatment programs, such as social therapy need to be evaluated. This is required by every relevant law that has come into force since the reform of the German federal system in 2006. Treatment and penal research would benefit if conventional designs comparing treated and untreated people, were supplemented by comparisons between organizations or organizational units with respect to success variables. This strategy, known as benchmarking in other sectors of society, has rarely been used in German penal research and is applied to social therapeutic treatment in the present article. Using data from a case documentation system, social therapy units in Lower Saxony were compared with respect to the allowance of privileges (temporary leave), treatment duration and employment status at the time of release. Multilevel models were applied. In all of the three dependent variables, distinct differences were found between the units that cannot solely be accounted for by the individual characteristics of the treated prisoners.     

"情绪智力量表(EIS)"的多元概化理论分析

本文运用多元概化理论对情绪智力量表(EIS)的测量信度进行探讨,得到以下研究结论:(1)EIS的整体测量信度较高,它既可用于常模参照测验,也可用于标准参照测验;在它的四个维度中,感知情绪、自我调控情绪和调控他人情绪维度有较好的测量信度,而运用情绪维度的测量信度稍差,需要改善;(2)EIS在决定各因子的分量比例方面不尽完善;(3)要想提高运用情绪因子的测量信度,除了增加运用情绪分量表的题目数外,还得改进题目的质量.

An Application of MCDM in Water Resources Problems

In this paper a practical application of MCDM in water resources problems is presented. Based on a real project for Qinhuangdao water resources management sponsored by Qinhuangdao Municipality, we construct a set of models for inflow forecast, reservoir operations, water supply and allocation, and flood routing for system optimal operation and flood management. A stochastic dynamic programming (DP) model with a fuzzy criterion is proposed for monthly reservoir operations. A series of goal programming (GP) models is built for water supply and allocation on different planning and operating levels. The DP–GP models fulfil the optimal operation tasks of a water resources management decision support system (WRMDSS) for Qinhuangdao water resources management.     

同质信度多种指标的比较研究

本研究采用实验研究方式．以被试人数、项目数和方差是否相等为3个自变量,研究随自变量变化因变景同质信度不同指标各自的稳定性。然后采用概化理论的研究方法对上述结果进一步验证。两种研究结果一致表明,α系数对方差是否相等比较敏感．不是同质信度的理想指标。β系数γ系数ζ系数对信度的估计精度基本处于同一水平．在抗干扰性上明显比。系数优越,但不及ρ系数。ρ系数在各种条件下都很稳定,能较准确地反映同质信度。     

风险投资从业人员的风险认知及其影响因素研究

本文根据Slovic等人提出的心理测量范式,设计了风险投资从业人员的风险认知研究问卷。对收集的数据用SPSS软件进行统计分析发现,风险投资从业人员对风险投资各风险因素有不同的风险认知结构,影响其风险认知结构的个人背景因素主要有年龄和单位性质。此外,性别和年龄、性别和专业的交互作用对其风险认知结构有极其显著的影响,性别和职务的交互作用对其风险认知结构有显著影响。     

Supervisors’ work-related and nonwork information sharing: Integrating research on information sharing,information seeking,and trust using self-disclosure theory

Although significant scholarly attention has been devoted to understanding subordinates’ information seeking from supervisors, researchers have not paid adequate attention to information sharing by supervisors. Moreover, research on supervisors’ information sharing behavior has focused almost exclusively on work-related information sharing, disregarding supervisors’ sharing of information not related to work (e.g., that related to family). Drawing on self-disclosure theory, we argue that supervisors share both work-related and nonwork information with their subordinates and propose that these two forms of information sharing are conceptually distinct. Furthermore, to unravel the role of supervisors’ nonwork information sharing, we develop an interactive model to test how it may be associated with important employee outcomes. We conducted pilot studies using five samples and, through a sixth study, tested the hypothesized model using a four-wave data collection design. This study makes three major contributions to research and theory. First, it integrates information sharing and information seeking literatures. Second, it underlines the importance of supervisors’ nonwork information sharing in organizations by testing its direct and interactive effects. Third, it contributes to theory by presenting trust as a mechanism that links information disclosure in dyads. Results obtained using structural equation modeling generally supported the proposed model.
