Categories and Facets in Integrative Levels

Facets and general categories used in bibliographic classification have been based on a disciplinary organization of knowledge. However, facets and categories of phenomena independent from disciplines can be identified similarly. Phenomena can be classified according to a series of integrative levels (layers), which in turn can be grouped into the major strata of form, matter, life, mind, society and culture, agreeing with Nicolai Hartmann’s ontology. Unlike a layer, a stratum is not constituted of elements of the lower ones; rather, it represents the formal pattern of the lower ones, like the horse hoof represents the shape of the steppe. Bibliographic categories can now be seen in the light of level theory: some categories are truly general, while others only appear at a given level, being the realization of a general category in the specific context of the level: these are the facets of that level. In the notation of the Integrative Level Classification project, categories and facets are represented by digits, and displayed in a Web interface with the help of colours.     

Children’s notions of the malleability of their academic competencies

This study set out to examine children’s notions of the malleability of their academic competencies and the relations of these notions to the child’s grade-level and gender and the parent’s educational level. In interviews of a total of 103 boys and girls of the third and the sixth grade, children of academically and vocationally educated parents were asked to rate their potential for improving their competencies in mathematics and Finnish. The children were asked to use intrapersonal and normative criteria in their ratings. The ratings were found to form distinct domains of the notions of malleability, as they did not correlate with each other. The children’s ratings of their current competencies, i.e. their academic self-concepts, turned out to be related to their normative ratings of the malleability of their competencies. The findings further suggested that the children’s notions of the malleability of their academic competencies became more pessimistic in the course of their school years.

晚发性抑郁的生物学机制

晚发性抑郁是指发病年龄大于60岁的一组抑郁综合征,发病机制至今尚不明确。研究表明,晚发性抑郁的遗传因素不明显,而血管损害则与之密切相关;多数患者伴有明显的执行功能损害,痴呆的发病风险增高。围绕晚发性抑郁的两个基本特征:血管损害与认知障碍做一回顾,初步探讨了晚发性抑郁生物学机制对临床决策的影响,并由此展望了未来的研究方向。     

Aging, Executive Functioning, and Social Control

ABSTRACT— Aging is associated with atrophy of the frontal lobes of the brain, which are the seat of executive functions. Because successful social functioning often requires executive control, aging can lead to unintended social changes via deficits in executive control. In this article I review evidence that, due to losses in executive control, aging leads to increased prejudice and social inappropriateness and, under certain circumstances, increased depression and problem gambling. I then discuss theory and research suggesting possible interventions that might ameliorate unwanted social changes brought about by executive decline.

Antecedents of Internet Retailing Loyalty: Differences Between Heavy Versus Light Shoppers

Purpose  The purpose of this study was to explore the moderating effects of heavy versus light shoppers on antecedents of customer’s satisfaction and loyalty toward an Internet retailer. Design/Methodology/Approach  A model discusses the different mechanisms in building an effective exchange relationship with light versus heavy shoppers was developed and tested using Internet book store as the study object. With the assistance of a marketing research firm, an Internet-based survey was employed to gather information on 375 users of Internet bookstores in Taiwan. Findings  The results showed that price/value had a stronger effect on overall satisfaction for light versus heavy shoppers, while trust had a stronger effect on overall satisfaction for heavy versus light shoppers. The study also found that consumers’ irreplaceable asset generated from past transaction with a focal Internet retailer had strong effects on their loyalty responses. Implications  Understanding of the moderating role of heavy versus light shoppers on satisfaction and loyalty formation helps to advance our theoretical understanding of the different routes of satisfaction and loyalty formation for different shoppers. The results of this study can help to inform the practitioners that price may play a role in drawing light shoppers, while perceived trust of the Internet store is more important in retaining heavy shoppers. It also demonstrated the importance of building asset specificity in increasing customer loyalty. Originality/Value  This is one of the first studies to provide evidence of the moderating effects of heavy versus light shoppers on satisfaction and loyalty formation. It explained and tested empirically the different mechanisms of satisfaction and loyalty formation between two groups of consumers.     

Mindfulness Meditation for Symptom Reduction in Fibromyalgia: Psychophysiological Correlates

Objectives Fibromyalgia, a chronic pain syndrome, is often accompanied by psychological distress and increased basal sympathetic tone. In a previous report it was shown that mindfulness-based stress-reduction (MBSR) reduced depressive symptoms in patients with fibromyalgia with gains maintained at two months follow-up (Sephton et al., Arthr Rheum 57:77–85, 2007). This second study explores the effects of MBSR on basal sympathetic (SNS) activation among women with fibromyalgia. Methods Participants (n = 24) responded to a television news appearance, newspaper, and radio advertisements. Effects on anxiety, depressive symptoms, and SNS activation measures were tested before and after MBSR using a within-subjects design. Results The MBSR treatment significantly reduced basal electrodermal (skin conductance level; SCL) activity (t = 3.298, p = .005) and SCL activity during meditation (t = 4.389, p = .001), consistent with reduced SNS activation. Conclusions In this small sample, basal SNS activity was reduced following MBSR treatment. Future studies should assess how MBSR may help reduce negative psychological symptoms and attenuate SNS activation in fibromyalgia. Further clarification of psychological and physiological responses associated with fibromyalgia may lead to more beneficial treatment.     

侗歌经验对侗族中学生执行功能的影响

音乐训练对认知能力具有广泛的促进效应。本研究结合执行功能的三个成分(抑制控制、工作记忆和认知灵活性), 在我国民族音乐背景下, 匹配实验任务的视觉和听觉形式, 探讨侗歌经验对侗族中学生执行功能的影响。结果表明, 侗歌组被试在抑制能力和刷新能力上显著好于侗族非侗歌组被试和汉族被试, 这一优势在视觉任务中和听觉任务中均存在, 说明侗歌经验产生的认知优势具有跨感觉通道的普遍性。侗歌组被试和侗族非侗歌组被试的转换能力差异不显著。侗族非侗歌组被试的抑制能力和转换能力好于汉族被试, 这体现了语言和音乐的交互作用。     

高校教师教学水平评价概化理论预算限制下最佳样本量估计

使用“高校教师教学水平评价问卷”,要求566名学生对19名教师进行评价,对收集到的数据作不同的概化设计,包括t×i、（s：t）×i、（s：t）×（i：v）和（s：t）×（i：v）×o四种设计。基于概化理论,结合预算限制,统一LaGrange乘法公式,自行推导不同设计的最佳样本量公式,联合估计的方差分量,计算出不同设计的最佳样本量。结果表明：（1）LaGrange乘法统一公式表现出较强的通用性,能够适用于预算限制下各种概化设计;（2）评价场合是影响高校教师教学水平评价一个相当重要的因素;（3）（s：t）×（i：v）×o是高校教师教学水平评价概化理论预算限制下最优概化设计;（4）高校教师教学水平评价概化理论预算限制下,每位教师最佳评价学生人数为20人,每个维度最佳评价题目数为3题。     

不同神经活动类型大学生注意网络的差异及神经机制

为探讨不同神经活动类型大学生注意网络加工的差异及神经机制,筛选灵活型、安静型、兴奋型和抑制型四种典型的神经活动类型大学生完成ERP版的注意网络测试任务。发现安静型组在警觉任务中诱发的N1波幅高于兴奋型和抑制型,定向加工中所诱发的N1波幅显著高于其他三种类型,可能说明安静型个体在警觉加工中投入相对更多的注意资源,且更好地将注意朝向了单侧化空间线索。执行控制加工中,灵活型在N2的难度效应量上（困难与简单试次在N2上的差值）显著大于其他三种类型,表明灵活型比其他类型的冲突检测更快、更敏感,证明了灵活型在执行控制加工效能与其他类型的差异主要来源于冲突检测阶段;在P3波幅上,兴奋型大于抑制型,可能反映了抑制型在冲突解决中比兴奋型投入更多的认知资源。
