用于处理不努力作答的标准化残差系列方法和混合多层模型法的比较

文章采用模拟研究, 分别在混合多层模型假设满足和违背的情境下, 比较了混合多层模型方法与标准化残差系列方法在识别不努力作答和参数估计方面的表现。结果显示：(1)不存在不努力作答或其严重性低时, 各方法表现接近; (2)不努力作答严重性高时, 固定参数迭代标准化残差法普遍更优, 混合多层模型法仅在假设满足且两种作答反应时差异大的条件下表现较好。建议实际应用中优先选择固定参数迭代标准化残差法。

童年期不良经历对中学生良心的影响：特质自我控制和自我损耗的链式中介作用

为探讨童年期不良经历对中学生良心的影响及作用机制,基于生物生态学理论和自我控制资源模型,采用整群取样法抽取湖南省7所城市7所中学初一到高三学生共3648名,使用童年期不良经历问卷、青少年良心问卷、特质自我控制量表和自我调节疲劳量表进行问卷调查。结果发现:(1)童年期不良经历负向预测中学生良心;(2)特质自我控制和自我损耗在童年期不良经历和中学生良心间起部分中介作用;(3)特质自我控制和自我损耗在童年期不良经历和中学生良心间起链式中介作用。研究结果表明,童年期不良经历不仅是影响中学生良心的重要外部因素,而且还会通过影响特质自我控制和经由自我损耗对中学生良心产生间接作用;减少和避免童年期不良经历对中学生心理的冲击,提升其特质自我控制水平,降低其自我损耗,是预防中学生良心失守和提升良心水平的重要途径。

Scan the QR Code of Happiness: Can Mobile Payment Adoption Make People Happier?

This research note investigates the association between mobile payment adoption and happiness. We employ the conditional mixed process model to address the selection bias and estimate the open-access 2017 Chinese General Social Survey data. Our findings reveal that mobile payment adoption significantly improves rural residents’ happiness but does not significantly influence urban residents’ happiness. Exploring gendered differences finds that regardless of urban or rural residence, females are happier than males when adopting mobile payment. Our findings suggest that promoting mobile payment adoption could bring favourable well-being returns.

     

Belief in a just world and organisational loyalty: Trust as an underlying mechanism

This research examined whether employees' personal belief in a just world (BJW) is associated with their organisational loyalty and whether this relationship is statistically mediated by organisational trust. To test these hypotheses, we conducted two studies with employees from China (study 1, N = 314) and Germany (study 2, N = 189). The results from both studies supported the proposed model. In addition, study 2 revealed that the relationship between BJW and organisational loyalty persisted when controlling for global personality traits. These suggest that managers and organisations may increase employees' loyalty by providing an environment that fosters their sense of justice and trust.     

Ranking 2010 in production and research productivity in Spanish public universities

The creation of the European Higher Education Area has brought the relevance of the scientific quality assessment in higher education. The result of this interest is a growing interest in the development of rankings of universities, both nationally and internationally. To continue the line started two years ago, the goal of this research is to update the ranking of research productivity in Spanish public universities with the data of 2010. We follow the same methodology to data from 2008 and 2009; although this year it includes measures of total production. The same indicators to evaluate research in 2009: journals articles indexed in the JCR, research periods, research + development projects, doctoral dissertations, grants for training university teachers, Doctoral Programs with Quality Mention and patents. From the results obtained show that universities with higher production were Complutense de Madrid, Barcelona and Granada. The most productive were the Pompeu Fabra University, the Pablo de Olavide, and the Autonoma de Barcelona.     

Assessment of emotional reactivity to food images in bulimia nervosa

The aim of the study was to assess the influence on reactivity to food images of the following variables: craving-trait, positive or negative mood state, and food restriction. Emotional modulation of the defense startle reflex (RMS) was assessed in 26 women at risk of suffering from bulimia nervosa; they were assigned one of to two groups: high craving-trait and low craving-trait. Before the test, positive or negative mood and restriction vs. non-restriction states were induced in each of the groups. Skin conductance response (SCR) and electromyogram activity from the orbiculari oculi region were recorded after the auditory stimuli; questionnaires such as Food Craving Trait Questionnaire (FCQ-T) and the Self-assessment Manikin (SAM) were used. Results showed that negative affect produced a negative valence of food images, more arousal, and more loss of control, as well as higher SCRs. Subjects with low FCQ-T levels reduced their RMS to food images as a consequence of experiencing positive emotions; when emotions were negative, their RMS increased.
