Image-processing algorithms for behavior analysis of group-housed pigs

Computational algorithms of image processing were developed and evaluated to select, by motion detection, images of resting artificial pigs and to segment the pigs (mixture of black and white pigs) from their background. Motion detection of the pigs was implemented by detecting interframe differences of postural behavioral images. This algorithm combines the advantages of likelihood ratio method and shading model method and shows a stable performance under noisy and dynamic illumination conditions. Segmentation of the pigs from their background was implemented by employing multilevel thresholding and background reference techniques. The algorithm automatically determines the number of thresholds needed and produces satisfactory segmentation when both black and white pigs with different image intensities are present at the same time (the most complicated situation). The reference background image is updated so that temporal changes in illumination and/or spatial changes of the pen condition have little effect on the performance of image segmentation. The algorithm employs statistical models of the pigs and background and Bayes hypothesis testing to obtain and update the exposed portion of the reference background. Linear filters were used in this process for updating the parameters. These algorithms will serve as essential components for a novel, behavior-based, interactive approach to assess and control thermal comfort of group-housed pigs, which is expected to result in enhanced animal health and well-being.     

Child-oriented family therapy in China: A cross-cultural application of integrative family therapy targeting children aged 4–10

This article describes child-oriented family therapy (COF), a family therapy approach to early psychological and behavioral problems that is widely applied in northern Europe and has been adopted by countries with different cultures, such as Germany and China. This article explains the theoretical background, setting, characteristics, development and effective factors of this method and explores relevant research. In addition, the application of this method in China and reflections on its applicability to families in different cultures are presented. A clinical case is provided to illustrate the core therapeutic principles of COF. Since the application of COF interventions to families with children in Asian cultures remains understudied, the widespread availability of COF and adaptation to local conditions could facilitate training and research achievements in this field.     

中学师生内隐智力观的发展研究

采用半结构式访谈调查与问卷调查相结合的方法,对中学师生的内隐智力观进行了研究。结果发现：在对聪明男女中学生重要特征的评定中,中学教师对于智力的理解多集中于与认知有关的因素,并且评价所涉及到的方面随被评价对象年龄增长而调整;中学生对于智力的理解多集中于与人际交往有关的因素,并且随着年龄增长表现出更加看重内在特征的趋势;中学教师与中学生的内隐智力观存在一致性,主要表现为他们对聪明特征的评定因被评价对象的年龄和性别不同而变化,也存在一定的差异,具体为教师和学生强调的方面有所不同。

养成训练:未成年公民品德塑造的新路径

重灌输轻养成、重理论教育轻行为训练是青少年道德建设成效不高的重要原因,而养成训练则被证明是未成年公民道德素质生成的有效路径.这是由品德生成的客观规律、未成年人身心发展的特点以及体验教育、实践育人的任务决定的.要切实提高道德行为习惯养成的实际效果,德目指标应易记易循,行为准则须明确具体;活动方案设计应贴紧未成年人实际,训练活动要注重可操作性,强化情感体验环节,抓好"小处"、"小事",注意训练活动的持续性和家校(园)之间的良性互动,不断巩固养成成果.实践证明,从基本道德行为习惯养成训练入手正是促进未成年人道德建设取得实效的关键所在.     

青少年自我描述归类与人格维度特点

对青少年自我描述的内容进行归类时发现,依据不同的归类标准会得到不同的人格结构。500多名青少年学生提供了620个不同的对自我的描述,除9个项目属于对身体和家庭状况的描述外,所有的人格特征既可以归属到中国青少年人格结构的19个二级因素,又可以归属到西方大五人格结构的30个层面。这一结果表明,外显的人格特征分类无法准确表达人格结构的实际构成,人格结构的确定还需要实证评定及对内隐结构的探索。文中还讨论了心理学研究中国化（本土化）的思路与策略。     

组织行为的完全归因模型

本文首先阐述了对组织行为进行归因认知的必要性,分析了组织行为的认知基础,在此基础上提出"完全归因"的概念并分析其要素与过程.为推进归因理论的社会应用,本文进一步给出了完全归因的初步模型.该模型充分考虑时空环境和心智环境的复杂性,并将归因推断与归因效果分析统一起来,对组织行为的归因认知过程进行了完整的描述.     

Measurement of self-evaluative motives: a shopping scenario

To develop measures of consumers' self-evaluative motives of Self-verification, Self-enhancement, and Self-improvement within the context of a mall shopping environment, an initial set of 49 items was generated by conducting three focus-group sessions. These items were subsequently converted into shopping-dependent motive statements. 250 undergraduate college students responded on a 7-point scale to each statement as these related to the acquisition of recent personal shopping goods. An exploratory factor analysis yielded five factors, accounting for 57.7% of the variance, three of which corresponded to the Self-verification motive (five items), Self-enhancement motive (three items), and Self-improvement motive (six items). These 14 items, along with 9 reconstructed items, yielded 23 items retained and subjected to additional testing. In a final round of data collection, 169 college students provided data for exploratory factor analysis. 11 items were used in confirmatory factor analysis. Analysis indicated that the 11-item scale adequately captured measures of the three self-evaluative motives. However, further data reduction produced a 9-item scale with marked improvement in statistical fit over the 11-item scale.     

过去时间的心理结构

４０８名大学生被试用秒、分、小时、日、星期、年和月７个时间单位和模糊统计试验方法对４０个不定的过去时间修饰词作经验赋值,结果显示：（１）过去时间和未来时间在心理结构上是对称的,分为三个心理时间段,即以秒和分为计时单位的“较近的过去”和“较近的未来”,以小时、日和月为计时单位的“近的过去”和“近的未来”,和以年为计时单位的“远的过去”和“远的未来”。（２）随着时间修饰词的词义离现在由近至远,其词义地
