This study of kindergarten-aged hyperactive children evaluated the effects of three modes of treatment in relation to an untreated control group. The treatments were administered over a 3-month period and included cognitive behavior modification, methylphenidate, and the two treatments combined. A follow-up assessment was done approximately 1 year later at the end of the first grade. Analyses of psychological, rating scale observational, and interview data showed that hyperactive children became less symptomatic over time;the data did not provide evidence indicating that any of the treatments studied was more effective than any other or than no treatment at all.This research was supported by grants from the Ontario Mental Health Foundation (Grant No. 701-76/78) and The Hospital for Sick Children Foundation (Grant No. 77-22). The authors wish to thank Mr. Syl Sauro, of the Etobicoke Board of Education, and Mrs. M. Stijovic, of the Etobicoke Community Health Department, for their cooperation. 相似文献

The centre of Adorno's Critical Theory is occupied by the theme of happiness. He speaks of the impaired life, of the unjustness of society, of murderous prejudices, of the atrocities in history, of the dissonance in art, of the unhappy consciousness, because something better can only be described from a point of opposition. Happiness cannot be objectified as possession, it always needs to be experienced subjectively, somatically. (With happiness it is like with truth: One does not have it, one is in it.) Happiness cannot be prescribed and ordered; nothing can be done to guarantee happiness. (Happiness goes beyond doing.) Happiness (like fear) has to do with being open to experience which can overwhelm the self. Sexual and aesthetical experience are models for such overwhelming happiness. The sensation of happiness always is very personal, but in this experience the individual leaves its particularity behind. One has to differentiate between goal and object: Happiness may be a goal, but not it itself, only what obstructs it, can be an object of Critical Theory. 相似文献

A novel three-dimensional eye tracker is described and its performance evaluated. In contrast to previous devices based on conventional video standards, the present eye tracker is based on programmable CMOS image sensors, interfaced directly to digital processing circuitry to permit real-time image acquisition and processing. This architecture provides a number of important advantages, including image sampling rates of up to 400/sec measurement, direct pixel addressing for preprocessing and acquisition, and hard-disk storage of relevant image data. The reconfigurable digital processing circuitry also facilitatesin-line optimization of the front-end, time-critical processes. The primary acquisition algorithm for tracking the pupil and other eye features is designed around the generalized Hough transform. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and head movement (six degrees of freedom), and thus provides the basis for many types of vestibulo-oculomotor and visual research. The device has been qualified by the German Space Agency (DLR) and NASA for deployment on the International Space Station. It is foreseen that the device will be used together with appropriate stimulus generators as a general purpose facility for visual and vestibular experiments. Initial verification studies with an artificial eye demonstrate a measurement resolution of better than 0.1° in all three components (i.e., system noise for each of the components measured as 0.006° H, 0.005° V, and 0.016° T. Over a range of ±20° eye rotation, linearity was found to be <0.5% (H), <0.5% (V), and <2.0% (T). A comparison with the scierai search coil technique yieldednear equivalent values for the systemnoise and the thickness of Listing’s plane. 相似文献

Some conceptions of minority influence have stressed the impact of the mere existence of an unpopular, deviant position. Others (e.g. Moscovici, 1980 ) have emphasized the active opposition of a committed minority to a powerful majority. An active advocate is defined as one that is aware of the level of support for his/her position, expresses his/her position openly, and whose outcomes may depend on others' agreement/disagreement. In the present study, the potential moderating role of an advocates' active/passive status on opinion change was examined. When the issue was highly relevant to the target of influence, all that mattered was the quality of the source's arguments (i.e. majority≈ minority, active source = passive source). When the issue was not highly relevant to the target, though, active and passive sources had different impact: (1) active sources prompted attention to argument quality (for minorities) and heuristic compliance (for majorities); (2) passive sources prompted insensitivity to both the popularity of the position and to the quality of the source's arguments.

Biomedicine is a global enterprise constructed upon the belief in the universality of scientific truths. However, despite
huge scientific advances over recent decades it has not been able to formulate a specific and universal definition of death:
In fact, in its attempt to redefine death, the concept of death appears to have become immersed in ever increasing vagueness
and ambiguity. Even more worrisome is that bioethics, in the form of principlism, is also endeavouring to become a global
enterprise by claiming neutrality. It appears that the discourse within both disciplines have similarly manipulated the boundaries
of death to include the “dying”. This paper argues that the redefinition of death debate in biomedicine reveals a concept
of personhood which is profoundly western in origin and which is in accordance to the concept adhered to within principlism.
Biomedicine and bioethics do not appear to acknowledge the limitations of their own world view and hence lack an understanding
of their applicability and appropriateness in diverse social and cultural contexts; a situation which adds credence to claims
as to the hegemonic and imperialistic nature of all such global enterprises.

The social climate of correctional (forensic) settings is likely to have a significant impact on the outcome of treatment and the overall functioning of these units. The Essen Climate Evaluation Schema (EssenCES) provides an objective way of measuring social climate that overcomes the content, length, and psychometric limitations of other measures. But the English translation of the EssenCES has yet to be sufficiently validated for use in forensic settings in the United Kingdom. The current study presents psychometric properties (factor structure and internal consistency) and an examination of construct validity with the English EssenCES. Satisfactory internal consistency was found for all EssenCES scales, and the expected three-factor structure was confirmed with both staff and residents and in prison and secure hospital settings using confirmatory factor analysis. Evidence to support construct validity was established using multilevel models, which showed statistically significant associations between scores on the EssenCES and scores on the Working Environment Scale, institutional aggression, and site security. Future validation work and potential practical applications of the EssenCES are discussed. 相似文献

This article analyses the recent changes in modern society (??second modernity??) and their importance for criminological questions. These changes increase the risk of biographical crises of individuals which can result in the committing of crimes. Therefore, a review of the diagnostic and prognostic system of ??applied criminology?? was necessary. As a result the ??applied criminology?? had to be adapted and a new biographical type of ??crime in crises?? was deduced from this review. The value orientation and individual relevant aspects, for example special places, persons or strong interests, play a key role in appraising the new biographical type of ??crime in crises??. This new type fits to the developments of the second modernity and completes the system of ??applied criminology??. 相似文献

At the end of the last decade severely violent and sexual crimes by previously convicted persistent offenders initiated a discussion about the necessity of quality control in the forensic psychiatric practice in Switzerland. Subsequently, measures similar to those in Germany were adopted, e.g. the implementation of a specialisation in forensic psychiatry. In addition, they included the creation of commissions with the duty of evaluating the dangerousness of serious offenders, the implementation of a standardized and certificated postgraduate training in forensic psychiatry and guidelines for the qualification of forensic assessment experts and the quality of reports. The following article presents the implemented measures and discusses their possible consequences for the quality of forensic psychiatric work. 相似文献
