When some of observed variates do not conform to the model under consideration, they will have a serious effect on the results of statistical analysis. In factor analysis the model with inconsistent variates may result in improper solutions. In this article a useful method for identifying a variate as inconsistent is proposed in factor analysis. The procedure is based on the likelihood principle. Several statistical properties such as the effect of misspecified hypotheses, the problem of multiple comparisons, and robustness to violation of distributional assumptions are investigated. The procedure is illustrated by some examples. 相似文献

Gabriel Marcel was a French, Catholic, existential philosopher who first presented the concept of human availability as a central way of strengthening the self and facilitating the experience of human freedom. In this article Marcel's ideas about availability are described, reviewed, and examined for their implications for the practice of existential psychotherapy with couples and families. 相似文献

A Bayesian approach for simultaneous optimization of test-based decisions is presented using the example of a selection decision
for a treatment followed by a mastery decision. A distinction is made between weak and strong rules where, as opposed to strong
rules, weak rules use prior test scores as collateral data. Conditions for monotonicity of optimal weak and strong rules are
presented. It is shown that under mild conditions on the test score distributions and utility functions, weak rules are always
compensatory by nature.
The authors are indebted to Wilbert Kallenberg for his valuable comments and to Jan Gulmans for providing the data for the
empirical example. The names of the authors are alphabetical; they are equally responsible for the contents of this paper. 相似文献

The importance of using culturally sensitive educational materials in HIV-related interventions with racial and ethnic minority groups is widely recognized. However, little empirical research has been conducted to assess the relative effectiveness of different techniques for creating culturally sensitive AIDS educational videos. Two field experiments with three samples of African American adults (N = 174, 173, and 143) were conducted to assess how source characteristics (race of communicator), message characteristics (multicultural message vs. culturally specific message), and audience characteristics (racial distrust and AIDS-related distrust) influence proximate (perceptions of the message's credibility and attractiveness) and distal (AIDS-related attitudes, beliefs, and behavioral intentions) output variables for AIDS educational videos. In Study 1, an AIDS video with a culturally specific message was rated as more credible, more attractive, and of higher quality than was a video with a multicultural message. The multicultural message was rated less favorably when delivered by a White announcer than when the announcer was Black. In Study 2, the same pattern was replicated with a second community sample and a campus-based sample. Study 2 also indicated that a multicultural message might be more effective if delivered in a culturally specific context, namely, after audience members watch a culturally specific video. Minimal changes were observed in distal outcome variables. It is argued that influencing proximate output variables is necessary, though not sufficient, for effecting long-term change in AIDS-related attitudes, beliefs, and behaviors. 相似文献

Therapists and parents were given vignettes describing the behavioural and emotional difficulties of two nine-year-old children and were asked to rate the importance of a number of possible explanations for such difficulties. Broad agreement was found between parents and therapists, but also there were a number of significant differences. Parents endorsed more child centered explanations and put greater emphasis on physical and developmental factors, while therapists endorsed relationships factors and saw the beliefs of other family members as important. Therapists who were parents showed a pattern of responses that lay between those of parents and non-parent therapists. 相似文献

Practitioners in Hong Kong have shown an increasing interest in various family therapy approaches since the 1980s. This paper offers a critique of the major concepts and techniques of the Satir model applied to families in Hong Kong. Cultural considerations are examined in relation to the family structure and hierarchy, the Chinese self and self-esteem, communication patterns, and family rules. Implications for the application of the Satir model of family therapy in Hong Kong are discussed. 相似文献

Should the nation provide expensive care and scarce organs to convicted felons? We distinguish between two fields of justice: Medical Justice and Societal Justice. Although there is general acceptance within the medical profession that physicians may distribute limited treatments based solely on potential medical benefits without regard to nonmedical factors, that does not mean that society cannot impose limits based on societal factors. If a society considers the convicted felon to be a full member, then that person would be entitled to at least a “decent minimum” level of care — which might include access to scarce life-saving organs. However, if criminals forfeit their entitlement to the same level of medical care afforded to all members of society, they still would be entitled to a kind of “rudimentary decent minimum” granted to all persons on simple humanitarian grounds. Almost certainly this entitlement would not include access to organ transplants. 相似文献

对听觉条件下中文字词劣效果的问题进行了实验考察,结果发现:在文章听点作业中,被试对高、低频目标字词语音的正误判断量存在着显著性差别,前者较后者成绩差,表现出字词劣效果的现象;在单字词的听点作业中,未发现被试对高、低频目标字词语音正误判断量方面的显著性差别;无论在文章还是单字词的听点作业中,被试对高、低频目标字词语音的正误判断量均比较低下,表明语音知觉的范畴性特征对字词语音的辩认准确性具有较大影响。 相似文献
