Ethnicity, Expressed Emotion, Attributions, and Course of Schizophrenia: Family Warmth Matters.

The authors examined the role of family factors and the course of schizophrenia by carrying out additional assessments and analyses in 2 previously published studies of Mexican American and Anglo American patients and families. The authors found partial support for an attributional model of relapse for families who are low in emotional overinvolvement. Attributions of control, criticism, and warmth together marginally predicted relapse. The data also indicated that for Mexican Americans, family warmth is a significant protective factor, whereas for Anglo Americans, family criticism is a significant risk factor. These findings suggest that the sociocultural context shapes the pathways by which family processes are related to the course of illness. Moreover, the warmth findings suggest that families may contribute to preventing relapse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Context-Processing Deficits in Schizotypal Personality Disorder.

Research suggests that schizotypal personality disorder (SPD) is a part of the spectrum of schizophrenia-related illnesses. This article hypothesizes that a deficit in the representation and maintenance of context is a core cognitive disturbance in schizophrenia and that SPD individuals should demonstrate context-processing deficits. To test this hypothesis, the authors administered 3 versions of their AX-CPT task, designed to assess context processing, to 35 healthy controls and 26 individuals with DSM-IV SPD. They also administered working memory and selective attention tasks. SPD individuals displayed context representation deficits similar to those found in schizophrenia but did not show the same additional deficits in context maintenance. Context processing was strongly associated with working memory and selective attention performance in the SPD individuals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

中文微博情感分析研究与实现

中文微博的大数据、指数传播和跨媒体等特性,决定了依托人工方式监控和处理中文微博是不现实的,迫切需要依托计算机开展中文微博情感自动分析研究.该项研究可分为3个任务：中文微博观点句识别、情感倾向性分类和情感要素抽取.为完成上述任务,我们研制了一个评测系统：通过构建多级词库、制定成词规则、开展串频统计等给出一种基于规则和统计的新词识别方法,在情感词和评价对象的依存模式的基础上给出基于词语特征的观点句识别算法;以词序流表示文本的LDA-Collocation模型,采用吉布斯抽样法推导了算法,实现中文微博情感倾向性自动分类;针对中文微博情感要素抽取的召回率较低问题,利用依存关系分析理论,按主语类和宾语类把依存模式分为2类,建立了6个优先级的评价对象和情感词汇的依存模式,通过评价对象归并算法实现计算机自动抽取情感要素.实验包括2个部分,一是参加NLPCC2012的公开评测,本文方法在微博观点句识别任务中的准确率为第2,在中文微博情感要素抽取任务中的准确率和F值均为第2,验证了本文算法的实用性.二是在分析公开评测结果的基础上,分别比较了参加公开评测的各类算法在处理中文微博情感分析时的效率,给出本文的结论.     

耳语音情感数据库的设计与建立

为了研究耳语音情感识别,制定了耳语音情感数据库的制作流程和制作规范,设计并建立了一个包含4000个单词、5000条语句和600个段落的耳语音情感数据库。利用模糊数学中的隶属度函数和层次分析法对语句的有效性进行了检验,得到一个满足研究要求的耳语音情感数据库。利用库中的语料进行初步的耳语音情感识别,得知正常音语音情感识别所用的音长、能量等参数,在耳语音中仍然可以使用;而正常音的其它涉及基音的一些参数,不适用于耳语音,需要进行改进或者提取新的特征参数。     

Erratum to Rodin and Langer.

Reports an error in "Long-term effects of a control-relevant intervention with the institutionalized aged" by Judith Rodin and Ellen J. Langer (Journal of Personality and Social Psychology, 1977[Dec], Vol 35[12], pp. 897-902). On page 900, the z score should be changed. The outcome is therefore only marginally significant, and a more cautious interpretation of the mortality findings than originally given is necessary. (The following abstract of this article originally appeared in record 1979-29338-001.) Reevaluated 26 elderly nursing home residents who were tested by the present authors (see record 1976-28515-001) as part of an intervention designed to increase feelings of choice and personal responsibility over daily events. Nurses' ratings and health and mortality indicators suggest that the experimental treatment and/or the processes that it set in motion had sustained beneficial effects.

实用语音情感的特征分析与识别的研究

 该文针对语音情感识别在实际中的应用,研究了烦躁等实用语音情感的分析与识别。通过计算机游戏诱发的方式采集了高自然度的语音情感数据,提取了74种情感特征,分析了韵律特征、音质特征与情感维度之间的关系,对烦躁等实用语音情感的声学特征进行了评价与选择,提出了针对实际应用环境的可拒判的实用语音情感识别方法。实验结果表明,文中采用的语音情感特征,能较好识别烦躁等实用语音情感,平均识别率达到75%以上。可拒判的实用语音情感识别方法,对模糊的和未知的情感类别的分类进行了合理的决策,在语音情感的实际应用中具有重要的意义。     

An experimental investigation on the poor hydrogen sorption properties of nano-structured LaNi5 prepared by ball-milling

Nano-structured LaNi₅ hydrogen storage materials prepared by ball-milling is analysed using differential scanning calorimetry (DSC) and x-ray photoelectron spectroscopy (XPS). DSC results indicate a partial elimination of defects at 500 °C in a more efficient way for the short-time ball-milled powders compared to the long-time ball-milled ones. XPS results show almost no change in the core-level electronic structure for La and Ni of LaNi₅ in the bulk and the nano-structured forms, but gives an indication that the self-restoring mechanism of the active surface observed in the bulk sample (Siegmann et al. Phys. Rev. Lett. 40, 972) may not be occurring in the nano-powders. Results from the X-ray diffraction and the local structural studies together with the above observations suggest that the reduced unit-cell volume and the enhanced atomic disorder in the nano-structured LaNi₅ cause a larger energy barrier for the hydrogen sorption reactions of the long-time ball-milled samples.
