In mid‐June 2009, the Obama administration dissolved the President's Council on Bioethics (PCBE), a group established by President George W. Bush in August 2001 and whose nearly eight‐year life was marked from beginning to end by controversy. While some will regret the PCBE's passing, others will regard the Council as a failed experiment in doing public bioethics.  相似文献

A recent factor analysis of the Multiple Affect Adjective Check List (MAACL) changed the Anxiety, Depression, and Hostility scales from bipolar to unipolar scales and added two new scales: Positive Affect and Sensation Seeking. Internal reliability of the MAACL-R scales, computed for normal and patient samples, was adequate for state and trait forms except for Sensation Seeking. Test-retest reliability in college students was higher for the trait form with retest intervals of from 2 to 8 weeks than for the state form with retest intervals of from 2 to 5 days. The pattern of correlations among self-, peer, and counselor ratings and the MAACL-R scales for normal and patient samples indicates improved discriminant validity and equally good convergent validity as the old scales. The use of standard scores that are indexed to the number of items checked reduced scale intercorrelations by controlling the acquiescence set.The financial support of the Weldon Springs Endowment Fund, University of Missouri at Kansas City, toward the completion of this research project is gratefully acknowledged.  相似文献

Cognitive assessment of depression is not well advanced and the evidence for the validity and reliability of measures is incomplete. This study examined two cognitive assessments of depression-the Automatic Thoughts Questionnaire (ATQ) and the Dysfunctional Attitudes Scale (DAS). There were two major objectives of this study. The first objective was to examine the ability of these two measures of cognitions to discriminate depressive symptomatology within a variety of sample populations-university undergraduate students, medical and psychiatric outpatients, and acute psychiatric inpatients. The second objective was to examine the ability of the ATQ and DAS succesfully to classify depressed and nondepressed patients. The results of this study suggest that the ATQ is a sensitive and specific measure of depression. Nonspecificity to the ATQ, however, was demonstrated in the substance abuse disorder group and the personality disorder group. In contrast, the DAS, although correlated with depressive symptomatology, was not found to be specific to depression.Part of this project is supported by a Special Project Grant from the University of Queensland to Dr. Oei.  相似文献

The acute effects of cocaine hydrochloride (4 to 96 mg/70 kg) and alcohol (0 to 1.0 g/kg), administered alone and in combination, were assessed in two experiments with human volunteers responding under a multiple schedule of repeated acquisition and performance of response chains. Subjects were intermittent users of cocaine and regular drinkers who were not cocaine or alcohol dependent. Alcohol was mixed with orange juice and ingested in six drinks within 30 min; cocaine was administered intranasally 45 min after completion of drinking. In each component of the multiple schedule, subjects completed response sequences using three keys of a numeric keypad. In the acquisition component, a new sequence was learned each session. In the performance component, the response sequence always remained the same. Results were consistent in both experiments, despite variations in the order in which the drugs were tested alone and in combination. Alcohol administered alone increased overall percentage of errors and decreased rates of responding in the acquisition component, whereas responding in the performance component generally was unaffected. Cocaine administered alone decreased rates of responding but did not affect accuracy of responding in the acquisition component, and enhanced accuracy of responding without affecting rates of responding in the performance component. The combined doses of cocaine and alcohol attenuated the effects observed with alcohol and cocaine alone. These results suggest that, under the conditions investigated in this study, (a) alcohol produces greater behavioral disruption than cocaine or cocaine-alcohol combinations, (b) cocaine and alcohol each attenuate effects of the other, and (c) such attenuation is most pronounced for cocaine attenuating the disruptive effects of alcohol.  相似文献

独生与非独生儿童认知发展的比较研究(广州市)   总被引:1,自引:0,他引:1  
为了研究中国独生子女政策可能造成的独生和非独生儿童的认知能力的差别,分别在广州七所小学一年级和五年级中选择了146名和171名独生与非独生儿童。用11项认知能力测验对这些儿童进行测查。一年级独生儿童在言语记忆和一般常识项目上的成绩优于非独生儿童。研究认为,一年级独生儿童在与一般认知能力有关的项目上具有优势。而五年级的独生儿童在认知作业成绩上,没有表现出显著性的优势。另外,独生男童在一般常识方面优于独生女童。作者用独生儿童受到较大的父母关注和投资来解释一年级独生对非独生儿童在认知方面的优势。随着儿童的自然成熟和学业教育,两者之间的差距会逐渐缩小,从而使五年级独生儿童未能在认知方面表现出明显的优势。  相似文献

Multivariate clustering procedures were used to identify homogeneous subgroups of outpatient sex offenders against children (n=110)on the basis of the Minnesota Multiphasic Personality Inventory (MMPI). Results indicated a five-subgroup solution. Two within-normal-limits and two clinically elevated profile subgroups replicated subtypes found in previous cluster analytic studies of child sex offenders. The fifth subgroup appeared similar in MMPI profile pattern and elevation to a previously identified subtype of rapists. Discriminant analyses showed that subgroups differed along dimensions of cognitive disturbance and sexual functioning. Furthermore, levels of psychopathology corresponded with levels of sexual pathology. Results are discussed with reference to previous MMPI cluster analytic studies of sex offenders and theories of sexual aggression.Portions of this paper were presented at the meeting of the Midwestern Psychological Association, 1992, Chicago, Illinois.  相似文献

Malgré le refus que Wittgenstein semble avoir toujours opposé à l'idée d'une esthétique philosophique, son oeuvre et les nombreuses suggestions que contiennent ses divers propos se révélent riches d'enseignements, en particulier pour ce qui concerne les voies dans lesquelles certaines formes de discours sur l'art se sot engagées. La notion wittgensteinienne dejeu de langage est, sous ce rapport, éclairante. Elle permet de mettre au jour, ou du moins d'entrevoir, deux catégories de faits. Tout d'abord, elle offre une perspective critique intéressante sur le programme de ce que l'on s'est plu à nommer une poétique, dans le prolongement d'Aristote, de Jakobson et de Valéry. La poétique structuraliste, en particulier, se révéle solidaire d'une philosophie que ses ambitions théoriques ne suffisent pas à occulter. En second lieu, la notion de jeu de langage, chez Wittgenstein lui-même, est associée à une pratique d'écriture originale qui obscurcit les frontiéres que la philosophie, depuis Platon, s'est toujours souciée de tracer. Pour une poétique des jeux de langage, il existe, entre la poétique et la philosophie une double symétrie. La premiére — celle des structuralistes ou des néo-structuralistes —obéit à un programme plus philosophique qu'on ne croit; la second, en revanche, comme on le voit avec Wittgenstein, intégr une démarche poétique qui nous invite à penser à nouveaux frais ce que nous faisons.  相似文献

Accurate perceptions of their child's academic performance are pivotal for parents' encouragement of their child's academic efforts. In research studies, parents' reports of their child's academic achievement, as well as the child's own reports, are often used as a proxy for teachers' ratings or grades. However, are parents' reports or their child's reports accurate and unbiased? We investigated whether ratings of academic performance made by mothers and their sons corresponded more closely to final grades and achievement test scores than did similar ratings made by teachers for three large samples of boys. Mothers' ratings correlated with final grades as well or better than teachers' ratings but more poorly with achievement test scores than did teachers' ratings. The seventh-grade boys' ratings correlated more poorly with both final grades and achievement test scores than did teachers' or mothers' ratings. Across all three samples combined, mothers were more likely to over-estimate rather than under-estimate the final grade. The same was true of the seventh grade sample of boys. Once the effect of final grade had been controlled, little evidence of a consistent pattern of associations between maternal demographic, parenting, and child behavior variables and either over- or underestimation was found.  相似文献
