Residualanalysis in the polytomous rasch model

Residuals for check of model fit in the polytomous Rasch model are examined. Comparisons are made between using counts for all response pattern and using item totals for score groups for the construction of the residuals. Comparisons are also, for the residuals based on score group totals, made between using as basis the item totals, or using the estimated item parameters. The developed methods are illustrated by two examples, one from a psychiatric rating scale, one from a Danish Welfare Study.     

An empirical test of a comprehensive model of intrapersonal empowerment in the workplace

A comprehensive model of intrapersonal empowerment in the workplace posits that empowerment mediates the relationship between the social structural context and behavioral outcomes. The social structural context is operationalized as perceptions of role ambiguity, sociopolitical support, access to strategic information and resources, and work unit culture, whereas behavioral outcomes are operationalized as innovativeness and effectiveness. The model is examined on a sample of 324 middle managers from different units of a Fortune 50 organization. Survey data are examined using a series of regression analyses to assess the mediating effect of intrapersonal. Results suggest that intrapersonal empowerment mediates the relationship between some elements of workplace social structure and innovativeness, but not effectiveness. Although not a mediating mechanism for effectiveness, intrapersonal empowerment is nonetheless directly related to effectiveness (as assessed by the respondent's subordinates). Implications of the results are discussed as are study limitations and directions for future research.

句子先提述的参与者在可提取性上的优势现象

下述五个实验就汉语句子成分（包括句子的参与者及其动作）的提述次序对其可提取性的影响进行了研究,结果表明：（１）句子先提述的参与者比后提述的参与者容易被提取,提述的次序对参与者的可提取性有明显影响。（２）先提述参与者的这种优势与句子呈现的方式有一定的关系。（３）在系列呈现的条件下,先提述参与者的易提取性与探测词呈现的延迟间隔有关。（４）在系列呈现的条件下,参与者以名词形式出现时,被试的反应速度较快,而参与者以名字的形式出现时,反应则较慢;在同时呈现的条件下这种差异基本消失。（５）句子参与者的行动（即句子的动词）的提述次序对其可提取性也有明显的影响,说明提述次序对句子成分的可提取性的影响,不只限于句子参与者本身。     

人格结构的动态分析

为了动态化地分析人格的结构。研究一采用个体性自由命名描述法考察人格的动态内容。１５０名大学生分别用１０个词描述实际的自我、理想的自我、应该的自我。词频统计反映了不同自我的内容特点。研究二采用常模化限定性描述法考察人格的结构特点,用研究珠高频词制成实际、理想、应该的自我词表。２００名大学生用７点量表分别评定各词表中的每个词适合描述相应的自我的程度。结果表明,实际的自我有５个因素,解释４７．１％的变异     

Utilizing structural family therapy and systems theory in the business world

The structure of businesses and the structure of families are very similar, considering the fact that so many businesses are owned or operated by families. Structural family therapists who are knowledgeable in systems theory and have an adequate understanding of the underlying concepts of structural family theory (including hierarchy, boundaries, and coalitions) can translate their knowledge to the structure of businesses and organizations. The purpose of this paper is to illustrate the similarities between the structures of families and businesses. In doing so, an application of structural family theory to the business world (employee assistance programs, business consultation, and family businesses) will be demonstrated.     

Psychopathy and structure of primary mental abilities

The Comprehensive Ability Battery (CAB) was used to assess 18 primary mental abilities in 53 white, male prison inmates for whom highly reliable ratings of psychopathy were available. None of the correlations between ratings of psychopathy and scores on the CAB tests was significant, and the overall pattern or structure of abilities was the same for inmates with low and high ratings of psychopathy. The possibility is raised that the personality characteristics of psychopaths make them appear to be brighter and more creative than they actually are. Compared with norms for male high school students, the inmates as a group generally performed well, falling near the 50th percentile on 11 of the tests. The inmates performed significantly better than the normative sample on tests of verbal ability, esthetic judgment, aiming, and representational drawing, and significantly worse on tests of ideational fluency, spontaneous flexibility, and word fluency.This research was supported by Grant MT-4511 from the Medical Research Council of Canada.     

The use of latent class models for assessing prerequisite relations and transference among traits

This paper presents a strategy for pairwise assessment which may be used to evaluate the nature of both prerequisite and transference relations existing among a set of traits. This strategy is appropriate for use both within a confirmatory context, in which an attempt is made to establish the validity of some specified set of relations among traits, as well as within an exploratory context, in which a search is made for unconjectured prerequisite and transference relations existing between pairs of traits. Both uses of this strategy are based on a variety of latent class models which are representative of various possible relational states existing between pairs of traits. Thus, the nature of trait relations may be investigated through the use of statistical assessments of both absolute and relative fit attained by these models. An application is presented to exemplify how this strategy may be used within the exploratory context.The author is obliged to Clifford Clogg, C. Mitchell, Dayton, and William Schafer for helpful comments made regarding a previous draft of this paper as well as to Mary Papageorgiou who provided access to the data which was considered in this study.     

Human Self-Domestication and the Evolution of Pragmatics

As proposed for the emergence of modern languages, we argue that modern uses of languages (pragmatics) also evolved gradually in our species under the effects of human self-domestication, with three key aspects involved in a complex feedback loop: (a) a reduction in reactive aggression, (b) the sophistication of language structure (with emerging grammars initially facilitating the transition from physical aggression to verbal aggression); and (c) the potentiation of pragmatic principles governing conversation, including, but not limited to, turn-taking and inferential abilities. Our core hypothesis is that the reduction in reactive aggression, one of the key factors in self-domestication processes, enabled us to fully exploit our cognitive and interactional potential as applied to linguistic exchanges, and ultimately to evolve a specific form of communication governed by persuasive reciprocity—a trait of human conversation characterized by both competition and cooperation. In turn, both early crude forms of language, well suited for verbal aggression/insult, and later more sophisticated forms of language, well suited for persuasive reciprocity, significantly contributed to the resolution and reduction of (physical) aggression, thus having a return effect on the self-domestication processes. Supporting evidence for our proposal, as well as grounds for further testing, comes mainly from the consideration of cognitive disorders, which typically simultaneously present abnormal features of self-domestication (including aggressive behavior) and problems with pragmatics and social functioning. While various approaches to language evolution typically reduce it to a single factor, our approach considers language evolution as a multifactorial process, with each player acting upon the other, engaging in an intense mutually reinforcing feedback loop. Moreover, we see language evolution as a gradual process, continuous with the pre-linguistic cognitive abilities, which were engaged in a positive feedback loop with linguistic innovations, and where gene-culture co-evolution and cultural niche construction were the main driving forces.
