Abstract. Ian Barbour's work, especially Religion in an Age of Science, is a comprehensive, balanced, and theologian-friendly guide to relations between science and religion. As a physicist and a theologian, Barbour is one of a handful of people who know both areas in depth and hence provide a bridge for others who are not dually educat ed. This is a very substantial accomplishment. His own position, however, is presented tentatively and, in the opinion of this author, is less radical than that demanded by his overt commitments vis-à-vis the contemporary scientific worldview. At two points, especially, his position appears modernist when it should be postmodern, in light of his own stated theological and scientific convictions: (1) his critique of the feminist and two-thirds-world position on the social construction of science, (2) his preference for a unified worldview at the cost of slighting issues of diversity and particularity. Nonetheless, he has made an immense contribution by providing the best and deepest survey of the sciences of astronomy, physics, and biology and their implications for Christian theology; it makes him one of the premier thinkers in the twentienth-century discussions of science and religion.  相似文献

Cats reject saccharin and cyclamate and are indifferent to dulcin, although they, like other mammals, prefer sucrose. The rejection threshold for saccharin found in this experiments, .0001 M, is about 2 log steps lower than a previously reported rejection threshold for sodium saccharin. Water produces a taste in cats adapted to their own saliva. The high sodium saccharin threshold may have resulted because the taste of the sodium saccharin was masked by the taste of the water solvent; however, saccharin may also be somewhat more aversive to the cat than sodium saccharin. Saccharin may produce an aversive taste because it stimulates receptor sites sensitive to substances bitter to man as well as those sensitive to sugars. In addition, saccharin may not be an effective stimulus for all sugar-sensitive sites.  相似文献

ABET 2000 Criteria encourages development of proficiency in professional responsibility in engineering as part of the undergraduate curriculum. This paper discusses the use of industrially sponsored capstone design projects to encourage active discussion of professional responsibility in engineering that naturally occurs during the engineering design process. The paper also discusses student participation in designing responses and approaches to issues such as engineering ethics. The paper includes specific examples of topics addressed by students and the approaches developed (by students) in addressing these issues. An earlier version of this paper was presented at the International Conference on Ethics in Engineering and Computer Science, Case Western Reserve University, Cleveland, March 21–24, 1999.  相似文献

Developmental perspectives have been part of family therapy for more than two decades with a primary focus on the family life cycle and individual development. Most efforts at recognizing a marital life cycle have subsumed marital tasks under rubrics based primarily on parental roles. This paper offers a marital life cycle based on marital development with specific tasks for each of four stages-the marital breakup and remarriage phases are not included here-and provides implications for therapy.  相似文献

Factor analytic studies of attention-deficit/hyperactivity disorder (ADHD) in children and adults have shown that second-order and bifactor models better represent ADHD symptoms than two- or three-factor models, yet there is far less evidence for a bestfitting model of ADHD in adolescence. Thus, the current study examined the factor structure of ADHD in adolescence and further evaluated the external validity of the best fitting model. Participants were 588 adolescents (22 % female; 366 with a childhood ADHD diagnosis; mean age 15.9 years) from the 8-year assessment of the Multimodal Treatment Study of Children with ADHD (MTA). ADHD symptoms were assessed via adolescent self-report, parent report, and teacher report on the SNAP-IV scale. Potential factor structures for the 18 symptoms of ADHD were tested for each informant, which included traditional one-factor, two-factor, and three-factor models of ADHD, as well as second-order factor (specific factors loading onto general factor) and bifactor (items loading onto both specific and general factors) models. Unique associations between external criteria and the identified factors of each informant’s best fitting model were examined. Although several of the proposed models exhibited good fit, the second-order two-factor model best accounted for ADHD in adolescence according to self-report and parent report, and the second-order three-factor model was optimal according to teacher report. Several key measurement issues emerged for the hierarchical bifactor models, such as numerous Heywood cases and out-of-bound parameter estimates, which rendered them unfit as optimal representations of ADHD in adolescence. These findings and the implications of the best fitting model of ADHD in adolescence suggest that a possible reorganization of this disorder may eventually aid clinicians in the accurate diagnosis of ADHD in adolescents.  相似文献

Whether children should be offered genetic testing for cancer risk is much debated but young voices are rarely heard in these conversations. The current study explored perspectives of genetic testing held by adolescents and emerging adults in families with Li Fraumeni syndrome (LFS). Twelve 12- to 25-year-olds in families with LFS completed qualitative interviews for this study. All believed that testing should be offered for children but many qualified this statement saying parental approval would be needed and testing should be optional. Genetic testing was seen as way to learn of risk status, allow for disease prevention efforts, and reduce uncertainty and anxiety. Perceived disadvantages included negative emotions associated with the testing result. Participants generally felt that children should be involved in the testing decision, but that parents could unilaterally decide to have a child tested in certain circumstances (e.g., young age, high risk). All who were aware of having been tested and of their test result (n = 7; 4 positive) said testing had no negative impact on their outlook and they agreed with the decision to undergo testing. Implications of these findings for clinical practice and future research are discussed.  相似文献

Although claimed differences in values have played a prominent role in recent U.S. politics, the value systems of typical Republicans and Democrats have not been evaluated within a relevant dimensional framework. In 4 studies, party members were compared on extrinsic (money, popularity, image) and intrinsic (intimacy, helping, growth) values. Republicans were consistently higher on extrinsic relative to intrinsic values, a pattern suggested by past research to be personally and socially problematic. In Study 4, Republicans were also lower in a different measure of prosocial values, derived from social-dilemma research. All studies found an interaction such that only nonreligious Republicans were lower than Democrats on the intrinsic value of helping needy others. Implications for contemporary political discourse are discussed.  相似文献

Schizophrenia is a universal disorder with strongly genetic aetiology. A constant prevalence rate, universally, in the face of reduced fecundity leads to the argument here that an evolutionary advantage exists, but not solely for schizophrenia. Possible areas of advantage are examined and it is argued that schizophrenia exists as a costly trade-off, in the evolution of Homo sapiens, as a by-product of a yet unknown uniquely human quality. The reason it has stayed in existence is due to a combination of advantages bestowed upon the kin, the group and, to a lesser extent, individuals who suffer from the disorder; these all contribute a different type of advantage, each of which alone would not be sufficient. Further, the evidence for the other advantages alone lack the rigour of evidence seen in the by-product theories, which provide as yet unparalleled comprehensive evolutionary evidence.  相似文献
