Correspondence analysis used complementary to loglinear analysis   总被引:1,自引:0,他引:1  
Loglinear analysis and correspondence analysis provide us with two different methods for the decomposition of contingency tables. In this paper we will show that there are cases in which these two techniques can be used complementary to each other. More specifically, we will show that often correspondence analysis can be viewed as providing a decomposition of the difference between two matrices, each following a specific loglinear model. Therefore, in these cases the correspondence analysis solution can be interpreted in terms of the difference between these loglinear models. A generalization of correspondence analysis, recently proposed by Escofier, will also be discussed. With this decomposition, which includes classical correspondence analysis as a special case, it is possible to use correspondence analysis complementary to loglinear analysis in more instances than those described for classical correspondence analysis. In this context correspondence analysis is used for the decomposition of the residuals of specific restricted loglinear models.  相似文献

Rats were used to determine whether stress-induced analgesia (SIA) can be produced by conditioning with interoceptive stimuli (LiCl) as with exteroceptive stimuli (footshock). SIA was measured using a tail-flick test. As expected, unavoidable footshock as well as conditioning with footshock produced SIA. In contrast, conditioning with LiCl failed to cause SIA. The findings support the notion of functional differences in neural substrates for conditioning by exteroceptive and interoceptive cue.  相似文献

The present study sought to investigate Paulhus' (1981) principal-factor deletion technique (PFDT), a factor analytic method for controlling for socially desirable responding. Adult subjects (N = 330) responded to both forms of the Eysenck Personality Inventory and a 32-item lie scale. Peer ratings of extraversion and neuroticism served as criterion measures. The factor deleted by PFDT more closely reflected neuroticism than impression management. Factors resulting from PFDT were considerably less valid and less content saturated than those emerging from an ordinary factor solution. The implications of these results are discussed from the perspectives of predictive and construct validity.  相似文献

Psychobiological Factors Predicting the Course of Breast Cancer   总被引:3,自引:0,他引:3  
Drawing on a carefully controlled sample of 52 women with a history of breast carcinoma and 34 healthy controls, this prospective study examined empirical associations between psychological factors and the progression of neoplastic disorders over a follow-up period averaging 624 days. Psychological variables were psychometrically assessed by self-report measures. A multiple regression analysis which controlled for disease stage at original diagnosis, age, total length of disease course, hematological factors, and blood chemistries measured at study onset showed neoplastic spread to be associated with a repressive personality style, reduced expression of negative affect, helplessness-hopelessness, chronic stress, and comforting daydreaming. The identified model of medical and psychological variables accounted for 56% of the observed variance. A psychobiological model of brain-body disregulation provided the best account of the observed associations between psychological functioning and the progression of disease. Future research is necessary to examine the role which psychological functioning may exert upon health-relevant behaviors that might blunt the benefits of professional health care.  相似文献

ABSTRACT A simple parable is introduced that serves as an analogy to the private/public self-focus distinction The analogy elucidates that the reliability of the effects observed by the private/public research direction is not the focus of the Wicklund and Gollwitzer critique Rather, the critique questions the validity of the explanations offered More importantly, the analogy implies the conclusion that construing social dependency as an issue of self-focus does injustice to both the social dependency and self-focus concepts  相似文献

Teacher-rated adjustment differences among young elementary school children from (a) a recent sample and a 1974 cohort, and (b) urban/suburban, male/female, and grade-level subgroups were examined. A problem behavior checklist (Classroom Adjustment Rating Scale) and a school competence measure (Health Resources Inventory) for 974 children from 5 urban and 5 suburban schools were completed by 101 first- to fourth-grade teachers. Children from the more current cohort were rated as significantly more maladjusted than those from the earlier sample on 8 of 10 adjustment variables. In the recent sample, girls and suburban children evidenced a greater number of school competencies and fewer problem behaviors than boys and urban children, respectively. The implications of these findings for the future use of the teacher rating scales are discussed.  相似文献

The purpose of this note is to formulate some weaker versions of the so called Ramsey test that do not entail the following unacceptable consequenceIf A and C are already accepted in K, then if A, then C is also accepted in K. and to show that these versions still lead to the same triviality result when combined with a preservation criterion.  相似文献

The paper puts forward the thesis of conceptual pragmatism: that there are pragmatic choices to be made between distinct but similar concepts within various contexts. It is argued that this thesis should be acceptable to all who believe in concepts, whether the believers are platonists, realists or anti-realists. It is argued that the truth of the thesis may help to resolve many long-standing debates, and that in any case it will lead to an extension of philosophical method. The paper then briefly considers the concepts of belief and desire as a case-study, and argues for the recognition of the practical reasoner's stance (to stand alongside Dennett's intentional stance), relative to which we should select concepts of belief and desire which are broadly cartesian.I am grateful to the following for their help (varying from detailed comments and criticisms on earlier drafts, to general advice and encouragement): David Archard, Simon Blackburn, Jack Copeland, Dan Dennett, Susan Levi, Christopher McKnight, Derek Parfit, Michael Slote, Tim Williamson, and Crispin Wright.  相似文献

The observation that men are usually more supportive of war than women had led several authors to suggest that masculinity plays a causal role in the decision to make war and stockpile nuclear arms. In order to examine the relationship between sex role orientation and attitudes towards war and nuclear weapons, gender and measures of sex role orientation were used to predict three attitudes about nuclear weapons and the use of military force. Two specific and two classes of hypotheses regarding the possible relationships among these variables were tested: masculinity, femininity, Masculinity × Femininity interaction, and Gender × Sex Role Orientation hypotheses. The results provided limited support only for the femininity hypothesis—that attitudes toward war are associated with feminine traits. However, neither masculinity nor femininity was found to be the only mediators of the gender/war attitude relationship, indicating that sex role orientation (and especially masculinity) should be given less emphasis when trying to explain the relationship between gender and attitudes toward war.The author gratefully acknowledges the helpful comments of Douglas Kenrick, Nancy Russo, and an anonymous reviewer on a earlier version of this paper.  相似文献
