该文提出了计量测验效度的一种统一方法。首先,根据测量目标由测验编制者提出一组可能的线性拟合模型,拟合模型的集合称作“测量目标结构空间”。然后运用实证性因素分析对各个假设的拟合模型进行多方面的拟合良好性检验。若其中的某一假设模型能最优地拟合预测资料,则该模型中的公共因素的方差总贡献与观测变量的总方差的比就可定义为该测验的效度 相似文献

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. 相似文献

An empirical test of a comprehensive model of intrapersonal empowerment in the workplace 总被引:9,自引:0,他引:9
Gretchen M. Spreitzer 《American journal of community psychology》1995,23(5):601-629
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 总被引:6,自引:0,他引:6
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。 相似文献

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. 相似文献

Individual and institutional conflict of interests in biomedical research have becomes matters of increasing concern in recent
years. In the United States, the growth in relationships — sponsored research agreements, consultancies, memberships on boards,
licensing agreements, and equity ownership — between for-profit corporations and research universities and their scientists
has made the problem of conflicts, particularly financial conflicts, more acute. Conflicts can interfere with or compromise
important principles and obligations of researchers and their institutions, e.g., adherence to accepted research norms, duty
of care to patients, and open exchange of information. Disclosure is a key component of a successful conflict policy. Commitments
which conflict with a faculty member's primary obligations to teaching, research, administrative responsibilities, or patient
care also need attention. Institutional conflict of interests present different problems, some of which are discussed in an
analysis of an actual problem posed by two proposed clinical trials.
This paper is adapted from a lecture presented to a Symposium on Scientific Integrity, Warsaw, Poland, 23 November 1995.
Daniel Steiner was Vice-President and General Counsel of Harvard University (1972–92) and in that capacity became familiar
with conflict of interest issues. He is currently Counsel to the Boston law firm. Ropes and Gray, and is Adjunct Lecturer
in Public Policy at the John F. Kennedy School of Government. Harvard University. 相似文献

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. 相似文献

Typically in large residential facilities for retarded persons, meals are served in an institutional style that does not appear to encourage appropriate peer interactions. An ecological program alternative is serving meals in a family style. The present study was designed to examine both the feasibility of serving family style meals and the effects of family style meal service on mealtime language. Five retarded young adult male residents, who had some conversational skills and appropriate table manners, participated in this study. The experimental design involved a multiple baseline analysis across meals (dinner, lunch, and breakfast). Observers coded the youths' mealtime verbalizations according to the type, content, and direction of the verbalizations and they recorded the length of the meals. The analysis of the verbalization data indicated that during family style meals the participants spoke substantially more often than during institutional style meals. Increases in peer-directed conversation about the meals primarily accounted for the verbalization changes. Family style serving also resulted in the youths spending more time with their meals. In addition, social validation measures suggested that the family style procedures were preferred by the consumers (participants, staff, and concerned community members). 相似文献
