大学生性别自我概念的结构

同时运用外显的自陈式量表和自行设计的内隐联想测验来研究大学生的性别自我概念 ,结果表明 :(1)运用内隐联想测验来测量内隐性别自我概念是可靠、有效、敏感的 ;(2 )在性别自我概念的内隐层面上 ,性别差异十分显著 ;在性别自我概念的外显层面上 ,除了女性正性量表外 ,其他量表上均未表现出显著的差异。 (3)性别自我概念是一个双重的结构 :包括一个内隐的性别自我概念和一个外显的性别自我概念 ,前者是一个一维的未分化的结构 ,后者是一个两维的结构 ,并且二者相对独立

精神分裂症患者团体绘画艺术干预

探讨团体绘画艺术治疗对精神分裂症患者生理、心理和社会功能康复效果。86名精神分裂症住院患者被随机分配到干预组或对照组。干预组被试接受团体绘画艺术干预活动,对照组从事其他康复活动。结果发现,干预组被试阳性与阴性症状量表总分低于对照组被试,大体评定量表分数高于对照组被试,自我概念总分高于对照组被试,生活质量问卷的躯体功能、心理功能和社会功能维度高于对照组被试。团体绘画艺术干预可以缓解精神分裂症患者的精神症状,促进患者自我概念和生活质量的提升。     

Theorising the emerging green prosumer culture and profiling green prosumers in the green commodities market

This paper explores the phenomenon of green prosumption with a view to theorising the phenomenon and highlighting the challenges and opportunities this particular subculture creates for marketers of green commodities. Narratives of young green prosumers were gathered from 18 phenomenological in‐depth interviews. Capturing green prosumer experiences and subjective meanings, three thematic categories of green prosumption practices, (a) contraction, (b) control, and (c) creation, are postulated in the study. It also highlights several unforeseen challenges as well as a vast array of opportunities emerging from the three green prosumer segments identified in the study: semi‐green prosumers, empowered green prosumers, and liberated green prosumers. This study provides green commodity marketers with a set of recommendations to exploit opportunities in these largely untapped market segments.     

大学新生生活困扰的初步研究

本研究尝试对大学新生的生活困扰问题做一个初步的调查。在广州市某大学新生入学的第一学期末对 2 97名新生用大学新生适应量表进行了测试。结果发现 :( 1 )大学新生的生活困扰涉及人际关系、专业与职业期望、独立生活、资源信息利用和学习等五大方面。 ( 2 )平均而言 ,大学新生明显感到困扰的三个方面依次是资源信息利用、人际关系和学习方面 ;而在专业与职业期望和独立生活两个方面没有感到明显的困扰。 ( 3 )在上述新生生活困扰的五个方面没有发现显著的性别差异。结论 :大学新生的生活困扰问题值得引起足够的重视 ,应该有针对性地采取一些干预措施。     

A Two-Tier Full-Information Item Factor Analysis Model with Applications

Motivated by Gibbons et al.’s (Appl. Psychol. Meas. 31:4–19, 2007) full-information maximum marginal likelihood item bifactor analysis for polytomous data, and Rijmen, Vansteelandt, and De Boeck’s (Psychometrika 73:167–182, 2008) work on constructing computationally efficient estimation algorithms for latent variable models, a two-tier item factor analysis model is developed in this research. The modeling framework subsumes standard multidimensional IRT models, bifactor IRT models, and testlet response theory models as special cases. Features of the model lead to a reduction in the dimensionality of the latent variable space, and consequently significant computational savings. An EM algorithm for full-information maximum marginal likelihood estimation is developed. Simulations and real data demonstrations confirm the accuracy and efficiency of the proposed methods. Three real data sets from a large-scale educational assessment, a longitudinal public health survey, and a scale development study measuring patient reported quality of life outcomes are analyzed as illustrations of the model’s broad range of applicability.     

The Trajectory of Counseling in China: Past,Present, and Future Trends

This article surveys the past, present, and future trends of counseling in China. Historically, mental health problems were addressed within the family. Currently, psychotherapy from trained practitioners is available on a limited basis, at least in urban settings. The challenge of mental health in China is tremendous, and the efforts to meet that challenge are encouraging. The authors recommend that in the future, prevention and intervention services be offered that are ecosystemic, strengths‐based, and culturally appropriate.     

Role of Surface Roughness in Hysteresis during Adhesive Elastic Contact

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments that show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P-h curves are not unique.
