The remit of the apparatus of professional ethics in the field of psychotherapy can be appropriately expanded so as to make the profession more socially responsible and thereby contribute to the ‘protection of the public’ that is said to be the main purpose of statutory regulation. Using ideas culled from the sociology of the professions, political theory and ethical discourse, it is proposed that ethical psychotherapy cannot take place if its overall social framework is itself profoundly unethical. Inclusivity and diversity are reframed as ethical professional practices. Questions of wealth, gender, sexuality and ethnicity are not only ‘social’ or ‘political’—they are also part of a morally imaginative expansion of what we mean by professional ethics. Attention is paid to the dangers of self-righteousness and moral tyranny.  相似文献

According to Philippe Rushton, the equalitarian fiction, a scientific hoax that races are genetically equal in cognitive ability, underlies the politically correct objections to his research on racial differences. He maintains that there is a taboo against race unequaled by the Inquisition. I show that while Rushton has been publicly harassed, he has had continuous opportunities to present his findings in diverse, widely available, respectable journals, and no general suppression within academic psychology is evident. Similarly, Henry Garrett and his associates in the LAAEE, dedicated to preserving segregation and preventing race suicide, disseminated their ideas widely, although Garrett complained of the equalitarian fiction in 1961. Examination of the intertwined history ofMankind Quarterly, German Rassenhygiene, far right politics, and the work of Roger Pearson suggests that some cries of political correctness must be viewed with great caution.Preparation of this paper was not supported by any grant, foundation, political, or religious organization.specializing in the history of psychology and psychological aesthetics.  相似文献

This paper examines the processes of organizational adaptation and competitiveness of firms in an emerging economy. The study is set in the Argentinian context of the 1990s when a combination of economic and political change triggered a massive change in the competitive context of indigenous firms. Two highly flexible firms and two less‐flexible firms are studied from the pharmaceutical and edible oil industries and longitudinal data are supplied to explore the determinants of organizational flexibility in those organizations.  相似文献

As one of a suite of natural science galleries in the National Museum of Scotland, Animal Senses presents a comprehensive overview of how animals have evolved senses as they have adapted to different ecological niches in order to find food or avoid predation. Using different sensory channels, they also have evolved means of communication to attract mates, deter rivals, and remain hidden from predators and prey. Some of the most extraordinary examples of evolution are those which mimic the appearance of another unrelated species or some feature of the environment such as a thorn on a bush or a piece of coral. New taxidermy and models, engaging text presented hierarchically, and fun interactives were developed specifically for this gallery in order to present an up-to-date review of senses and communication. However, its real strength is the wide array of real specimens and life-size models which allow visitors to see what these animals really look like and how big they are, experiences which cannot be emulated by books or electronic media. By taking a thematic approach, we have created an unrivalled opportunity to compare animals from different taxonomic groups to see how they have solved the problems of life by evolving similar structures or completely different ones in order to find food, avoid being eaten, navigate, find mates and deceive rivals and predators.  相似文献

In this paper the relationships between a disruption in parental co-habitation and various categories of adolescent outcomes over multiple time horizons are explored. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we estimated the effects of a change from living with both parents to just one, on academic and employment outcomes, the likelihood to indulge in risky behaviors, mental health outcomes and body mass index measures, from less than 1 year to over 14 years after the change. Propensity score matching methods were used to control for individual characteristics and pre-existing differences in the family environment that may increase the chances of separation, and the results are compared to those obtained using ordinary least squares or probit methods. Results showed evidence of adverse effects of living with one parent in the short term, medium term and long term. Adolescents living with one parent had lower academic achievement in all term lengths, poor mental health in the short to medium term, and were more likely to engage in risky behaviors in the medium to long term.  相似文献

The depths, which have been used to detect outliers or to extract a representative subset, can be applied to classification. We propose a resampling-based classification method based on the fact that resampling techniques yield a consistent estimator of the distribution of a statistic. The performance of this method was evaluated with eight contaminated models in terms of Correct Classification Rates (CCRs), and the results were compared with other known methods. The proposed method consistently showed higher average CCRs and 4% higher CCR at the maximum compared to other methods. In addition, this method was applied to Berkeley data. The average CCRs were between 0.79 and 0.85.  相似文献
