初中生感知校园氛围与网络游戏成瘾的关系:学业自我效能感的中介效应与父母学业卷入的调节效应

采用问卷法对462名初中生进行调查,考察了初中生学业自我效能感在感知校园氛围与网络游戏成瘾(Internet gaming disorder, IGD)关系间的中介效应,以及父母学业卷入对这一中介过程的调节效应。结果发现:(1)在控制了性别、年龄、家庭月收入和父母受教育水平后,感知校园氛围显著负向预测初中生IGD;(2)学业自我效能感在感知校园氛围与IGD关系间起着显著的部分中介效应;(3)父母学业卷入对中介路径"感知校园氛围→学业自我效能感→IGD"具有显著的调节效应,即相对于父母学业卷入水平低的初中生而言,这一间接效应对于父母学业卷入水平高的初中生更强。实践干预时,可以通过提高青少年的学业自我效能感和/或调整父母学业卷入程度来预防和控制青少年IGD。     

用户运动信息反馈形式对体感操作用户体验的影响——一项基于Kinect的可用性研究

体感交互是新兴的人机交互方式;当前,相关的人因学研究相对缺乏。本研究采用典型任务结合主观评价法,首次探索了用户运动信息反馈形式对体感交互用户体验的影响。笔者从易学性、控制性、情感与心理负荷四个方面,比较了有、无人形反馈形式对游戏体感菜单操作可用性的影响。结果发现,二者在心理负荷上无差异,无人形反馈在易学性上优于有人形,但有人形反馈在控制感上优于无人形,且更受用户喜爱。基于该结果,笔者建议在体感操作界面上使用有人形反馈。     

Lorsque la logique rencontre l'argumentation

It is well known that classical logics are able to represent only some aspects of ordinary reasoning. In particular, by accepting the law of obversion, they remove the possibility of defining any but a propositional negation; certain natural uses of negation thus elude them. Logical theories do exist, however, that are exempt from such limitations. Among these theories are those of S. Leniewski, which differ profoundly from classical formal systems. Unlike the latter, they do not have a determined list of functors of syntactical-semantical categories. Due to formalized directives for definitions, the logics of Leniewski are constructed progressively, making new theses and consequently functors of new syntactical-semantical categories accessible. In this article we use some of these theses-definitions to define a principle of appropriateness. With this principle it is possible to represent certain logical subtleties that are used quite naturally but are neglected due to the law of obversion.

组织公正和职位对进谏行为的影响

本实验目的在于验证组织是否公正、职位的高低对进谏行为的影响.选取158名大学生为被试,采用2×2完全随机设计,以情境故事法呈现刺激,研究了组织公正与否、职位的高低对进谏行为的影响.结果表明,组织氛围(公正/不公正)的主效应显著,职位的主效应不显著,组织氛围与职位的交互作用显著,具体表现为:低职位的在组织氛围不同情况下,进谏行为差异显著;而在组织不公正的氛围下,职位不同其进竦行为差异显著.     

工作-家庭支持的结构与测量及其调节作用

在深度访谈和开放式问卷调查的基础上, 编制了工作-家庭支持问卷。探索性因素分析和验证性因素分析结果表明, 中国文化背景下的工作-家庭支持由组织支持、领导支持、情感支持和工具性支持四个维度构成。问卷的信效度指标良好。无约束结构方程模型分析结果表明, 工作-家庭支持能够有效调节工作-家庭冲突与离职意向的关系。     

Latent variable selection in multidimensional item response theory models using the expectation model selection algorithm

The aim of latent variable selection in multidimensional item response theory (MIRT) models is to identify latent traits probed by test items of a multidimensional test. In this paper the expectation model selection (EMS) algorithm proposed by Jiang et al. (2015) is applied to minimize the Bayesian information criterion (BIC) for latent variable selection in MIRT models with a known number of latent traits. Under mild assumptions, we prove the numerical convergence of the EMS algorithm for model selection by minimizing the BIC of observed data in the presence of missing data. For the identification of MIRT models, we assume that the variances of all latent traits are unity and each latent trait has an item that is only related to it. Under this identifiability assumption, the convergence of the EMS algorithm for latent variable selection in the multidimensional two-parameter logistic (M2PL) models can be verified. We give an efficient implementation of the EMS for the M2PL models. Simulation studies show that the EMS outperforms the EM-based L₁ regularization in terms of correctly selected latent variables and computation time. The EMS algorithm is applied to a real data set related to the Eysenck Personality Questionnaire.     

儿童期虐待对大学生公正世界信念的影响:有调节的中介模型

为探讨儿童期虐待对公正世界信念的作用及心理机制,本研究采用问卷法对929名大学生进行了调查,并采用潜变量模型对数据进行了分析。结果发现:(1)儿童期虐待显著负向预测大学生公正世界信念;(2)控制感在儿童期虐待与公正世界信念之间起完全中介作用;(3)家庭社会经济地位调节了儿童期虐待与控制感的关系,高家庭社会经济地位放大了儿童期虐待与控制感间的负相关。研究结果表明,可以通过预防儿童虐待和增强控制感等干预措施来提升公正世界信念,并且需要对高社会经济地位家庭的儿童虐待加大关注。
