Consulting relationships differ from traditional counseling and psychotherapeutic relationships in several fundamental ways. These differences require special consideration in evaluating ethical questions and conflicts, identifying ethical parameters within any given situation, and using existing ethical guidelines in determining appropriate courses of action. Currently, formal guidelines specific to the practice of consultation are not available, and existing codes of ethics for the helping professions provide only limited guidance for consultation practice. Consequently, consultants bear a heavy personal responsibility for the consequences of their professional decisions and actions. In this article the author reviews several important ethical issues relevant to consultation and examines their implications for consultation practice. 相似文献

In Science as Social Knowledge, Helen Longino offers a contextual analysis of evidential relevance. She claims that this “contextual empiricism” reconciles the objectivity of science with the claim that science is socially constructed. I argue that while her account does offer key insights into the role that values play in science, her claim that science is nonetheless objective is problematic. 相似文献

Abstract. This paper is on Ward Goodenough's recent article (27: 3), suggesting that his points can be clarified by reiterating the distinction between the realms of meaning and relevance. Religion's "truth" is in the form of its ualue; the "proof" which it requires is uindication; and the resulting "faith" must be understood as commitment. 相似文献

An alternating treatments design was used to compare the effects of Active Student Response (ASR) error correction and No Response (NR) error correction during instruction of the capitals of states and countries. Three students with learning disabilities were provided one-to-one daily instruction on four sets of 14 unknown capitals (7 ASR capitals and 7 NR capitals). Student errors during instruction on ASR capitals were immediately followed by the teacher stating the capital and the student repeating it (an active student response). Errors on NR capitals were immediately followed by the teacher stating the capital while the student visually attended to a geography card with the correct capital handwritten on it (an on-task response). During instruction each of the three students correctly stated more capitals taught with ASR instruction than he or she stated with NR error correction. Results of same-day and next-day tests show that all three students learned more capitals with ASR error correction than with NR error correction The students also correctly stated more ASR error correction capitals on 1-week maintenance tests. 相似文献

In February 1993, Judge Charles R. Richey of the United States District Court issued a summary judgment in the case of Animal Legal Defense Fund, et al. v. The Secretary of Agriculture, et al. The decision, which was in favor of the Animal Legal Defense Fund, requires the U.S. Department of Agriculture to withdraw its current regulations governing exercise for dogs and the psychological well-being of nonhuman primates used for biomedical research and to issue new regulations containing only minimum, measurable standards. Both plaintiffs and defendants contended that they were seeking the best interests of the laboratory animals. The issue at stake is whether animals are better protected if the government establishes limited minimal standards or is allowed to require institutions to provide additional standards, which will be judged on the basis of their effectiveness in maintaining healthy animals. The Court avoided this dispute, however, by placing primary emphasis on applying the Administrative Procedures Act and stating that it was merely interpreting the "plain meaning" of the Animal Welfare Act, as amended. In this article, arguments are presented for interpreting the law in a far more flexible way than Judge Richey did. The conclusion is also reached that there were no winners in the Animal Legal Defense Fund case and that the real losers are the laboratory animals. 相似文献

Predictive testing for Huntington disease is presently offered in a select few medical genetics centers in the United States. This is in part due to the labor intensive counseling and psychological testing suggested by the research protocols. We discuss some specific suggestions for establishing programs for Huntington disease predictive testing within pre-existing medical genetics clinics to encourage more centers to offer presymptomatic testing. This will allow more at risk individuals the opportunity to consider predictive testing and cut down the expenses of traveling to the few predictive testing centers that currently exist. The counseling principals will remain similar to those discussed here, even following the identification of the Huntington disease mutation. 相似文献

We present a multiple regression model that explores post-return adjustment of school-age children who experienced abduction by a parent. The model includes: a) child and family characteristics preceding abduction, b) characteristics of the abduction experience, and c) child and family characteristics following return. Overall, the model accounts for 21% of the variance in post-return adjustment of children (p.05). The most salient finding is that post-return adjustment of children was best explained by characteristics of the child and family before the abduction occurred. Domestic violence perpetrated by one or both parents was the most significant factor. 相似文献
