The manner in which the conditional independence graph of a multiway contingency table effects the fitting and interpretation of the Goodman association model (RC) and of correspondence analysis (CA) is considered.Estimation of the row and column scores is presented in this context by developing a unified framework that includes both models. Incorporation of the conditional independence constraints inherent in the graph may lead to equal or additive scores for the corresponding marginal tables, depending on the topology of the graph. An example of doubly additive scores in the analysis of a Burt subtable is given.Thanks are due to anonymous referees who substantially improved the original draft of this paper.  相似文献

The so-called optimising conception of rationality includes (amongst other things) the following two claims: (i) that it is irrational to choose an option if you know there is a better one, and (ii) there are no situations in which an agent, through no practical fault of her own, cannot avoid acting irrationally. As part of his ongoing attempt to explain why we need to go beyond the optimising conception, Michael Slote discusses a number of examples in which it seems that (i) and (ii) are inconsistent. According to Slote, these situations seem to involve the existence of rational supererogation (a denial of (i)), or rational dilemmas (a denial of (ii)). The purpose of this paper is to examine Slote's arguments for these claims, and to propose an alternative solution to the problem he presents.  相似文献

In a 2 × 2 × 2 × 2 (age restriction vs. no age restriction × sex of subject × pornography vs. nonpornography × pre-stimuli vs. post-stimuli test) factorial design, 40 males and 40 females received an experimental booklet containing either pornographic or nonpornographic pictures. Prior to seeing the pictures, half of the subjects of each sex were informed that the photographs came from magazines for adults only (21 years old and over), while the other half received no such information. Subjects were asked to rate the desirability of the pictures as well as their liking of and desire to read and purchase such materials prior to viewing and after viewing the pictures. The results indicated that (a) subjects who were not given age restriction information rated the yet unseen pictures more desirable than subjects who received age restriction information; (b) subjects who were given age restriction information rated the already seen pictures more desirable than subjects who received no age restriction information; (c) males rated pornographic pictures more favorably than did females; (d) subjects in the age restriction information condition expected the yet unseen pictures to be more pornographic than subjects in the no age restriction information condition; and (e) subjects, after seeing the stimuli, rated nonpornographic pictures more desirable than pornographic pictures. There was no support for the hypothesis that the effect of age restriction is an anticipatory phenomenon. The data in part supported and in part conflicted with Fromkin and Brock's (1973) proposition that imposing restrictions on the sale or purchase of pornographic materials will make these materials more attractive and desirable than they would be if there were no restrictions on them.  相似文献

This study was designed to ameliorate encopresis in a 6-year-old male child in the school setting. The procedure consisted of toilet training, cueing, praise, and self-cleaning. Prior to intervention, encopresis was a daily event at home and school. The intervention was successful in reducing the soiling to near zero at school, with no reported changes at home. Implications discussed for school psychologists were: (a) handling the intervention through a consultation model, (b) using the simplest approach before attempting more powerful procedures, and (c) attempting treatment in spite of the fact that other treatment attempts at home had been unsuccessful.  相似文献

A disposition index, DI, which provides information about each possible placement to be considered in a personnel classification situation is discussed. The index is readily computed by machine methods and can be used by counselors required to make assignments. The use of the disposition index provides an adequate approximation to optimal solutions obtained by other methods.This report is based on work done under ARDC Project No. 7702, Task No. 17051, in support of the research and development program of the Air Force Personnel and Training Research Center, Lackland Air Force Base, Texas. Permission is granted for reproduction, translation, publication, use, and disposal in whole and in part by or for the United States Government.  相似文献

The corporatization of U.S. health care has directed cost containment efforts toward scrutinizing the clinical decisions of physicians. This stimulated a variety of new utilization management interventions, particularly in hospital and managed care settings. Recent changes in fee-for-service medicine and physicians' traditional agency relationships with patients, purchasers, and insurers are examined here. New information systems monitoring of physician ordering behavior has already begun to impact on physician autonomy and the relationship of physicians to provider organizations in both for-profit and ‘not-for-profit’ sectors. As managed care practice settings proliferate, serious ethical questions will be raised about agency relationships with patients. This article examines health system dynamics altering the historical agency relationship between the physician and patient and eroding the traditional autonomy of the medical profession in the United States. The corporatization of medicine and the accompanying information systems monitoring of physician productivity is seen to account of such change, now posing serious ethical dilemmas.  相似文献

Improvements in parenting skills do not necessarily lead to improvements in child and parent outcomes for children with attention deficit and hyperactivity disorder (ADHD). Cognitive factors such as parental cognitions and parenting self-efficacy may influence such outcomes. Clinical research on the effects of cognitive-behaviour therapy (CBT) on parental cognitions, parenting self-efficacy and mental health in Chinese parents of children with ADHD is lacking. This quasi-experimental study intended to assess the effects of a culturally attuned group CBT treatment on the mental health and quality of life of Chinese parents aged 26–58 years, with children with ADHD in Hong Kong. Participants in the experimental group received group CBT and standard treatment and their counterparts in the control group received standard treatment. Primary outcome variables of mental health and quality of life and process variables including parenting stress, parenting efficacy and dysfunctional attitudes were measured at baseline, post-treatment and 3-month follow-up. Data were analysed using 2?×?3 ANCOVAs, Cohen’s d statistics and multiple mediation analyses. Group by time interactions were found for most outcome variables. Effect size statistics indicated that group CBT had small to moderate effects on most outcome variables at post-treatment and follow-up assessments. The effect of CBT on mental health was mediated by the reduction in parenting stress and the effect of CBT on quality of life was mediated by the reductions in parenting stress and dysfunctional attitudes. Given its potential benefit, it is worth considering incorporating this group CBT programme into interventions for Chinese parents with ADHD children.  相似文献
