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

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.

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

In two experiments, we investigated whether onsets and rimes have a role in the processing of written English. In both experiments, participants detected letter targets (e.g., t) in nonwords like vult faster than in nonwords like vust. This finding is consistent with Selkirk's (1982) view that sonorants (e.g., the /l/ of vult) cohere with preceding short vowels and are part of the vowel nucleus. In contrast, the /t/ of vust is part of the syllable's coda st and so is harder to isolate. Experiment 2 demonstrated that the time required for one to detect single-member codas following vowel digraphs (e.g., the t in veet) was similar to the time to detect the same target letter following a postvocalic sonorant (e.g., the t in vult). No evidence was found for onsets. The results provide support for a phonological organization among letters of printed rimes. 相似文献

The traditional form of the backward induction argument, which concludes that two initially rational agents would always defect, relies on the assumption that they believe they will be rational in later rounds. Philip Pettit and Robert Sugden have argued, however, that this assumption is unjustified. The purpose of this paper is to reconstruct the argument without using this assumption. The formulation offered concludes that two initially rational agents would decide to always defect, and relies only on the weaker assumption that they do not believe they will not be rational in later rounds. The argument employs the idea that decisions justify revocable presumptions about behavior. 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

Literacy and numeracy are important skills that are typically learned during childhood, a time that coincides with considerable shifts in large‐scale brain organization. However, most studies emphasize focal brain contributions to literacy and numeracy development by employing case‐control designs and voxel‐by‐voxel statistical comparisons. This approach has been valuable, but may underestimate the contribution of overall brain network organization. The current study includes children (N = 133 children; 86 male; mean age = 9.42, SD = 1.715; age range = 5.92–13.75y) with a broad range of abilities, and uses whole‐brain structural connectomics based on diffusion‐weighted MRI data. The results indicate that academic attainment is associated with differences in structural brain organization, something not seen when focusing on the integrity of specific regions. Furthermore, simulated disruption of highly‐connected brain regions known as hubs suggests that the role of these regions for maintaining the architecture of the network may be more important than specific aspects of processing. Our findings indicate that distributed brain systems contribute to the etiology of difficulties with academic learning, which cannot be captured using a more traditional voxel‐wise statistical approach. 相似文献
