Tobacco, alcohol, and drug use are problems for American-Indian people. We reviewed these problems and the explanations for them and described a bicultural competence skills approach for preventing substance abuse with American-Indian adolescents. Data from a study of that approach suggest its efficacy with American-Indian youth. At posttest and a 6-month follow-up, American-Indian subjects who received preventive intervention based on bicultural competence skills concepts improved more than did American-Indian subjects in a no-intervention control condition on measures of substance-use knowledge, attitudes, and interactive skills, and on self-reported rates of tobacco, alcohol, and drug use. Our findings have implications for future substance-abuse prevention research with American-Indian people.  相似文献

When a sentence with more than one clause is processed, words of the first clause become less available for recall or recognition once the clause boundary has been passed. One common interpretation of this observation is that the representation of a given word shifts from a predominantly surface form (e.g., phonological or lexical) to a semantic form, after the clause boundary. Two experiments that test that interpretation are reported. In the first experiment, two-clause spoken sentences were followed by spoken word or picture probes. Pictures were intended to provide a fast semantic match to probed words, but a slow surface match. Although response times exhibited a robust main effect of the clause position of the probe, no interaction with probe type was found. Similar results were obtained in a second experiment that compared pictures with written word probes. The faster response to picture than to word probes in the second experiment indicates that subjects did not covertly name the picture, but made a semantic match (as intended). These observations suggest the following reinterpretation of earlier sentence memory experiments: Words in the most recent clause of a sentence are more available than words in an earlier clause because their semantic representations are more active, not because their surface representations are more active.  相似文献

In its first part, this paper shows why a recently made attempt to reduce the special theory of relativity to Newtonian kinematics is bound to fail. In the second part, we propose a differentiated notion of incommensurability which enables us to amend the contention that the special theory of relatively and Newtonian kinematics are incommensurable.  相似文献

Eight pigeons were trained to discriminate between sets of color photographs of natural scenes. The scenes differed along five two-valued dimensions (site, weather, camera distance, camera orientation, and camera height), and all combinations of the feature values were used. One value of each dimension was designated as positive, and slides containing three or more positive feature values were members of the positive stimulus set. Thus, each feature had an equal, low, correlation with reinforcement, and all features had zero correlations with each other. Seven of the 8 pigeons learned this discrimination, and their responding came under the control of all five features. Within the positive and negative stimulus sets, response rates were higher to stimuli that contained more positive feature values. Once discrimination had been achieved, reversal training was given using a subset of the slides. In this subset, only a single feature was correlated with reinforcement. All pigeons learned this reversal successfully and generalized it to additional photographs with the same feature content. After reversal, the original reinforcement contingencies were reinstated, and training was continued using all the slides except those that had been used in reversal. Reversal generalized to these slides to some extent. Analysis of the response rates to individual slides showed that, compared with prereversal training, only the feature that had been subjected to reversal contingencies showed a reversed correlation with response rate. The remaining features showed the same correlation with response rate as they had before reversal training. Thus, reversal on some members of a category following category discrimination training led to generalization to stimuli within the category that were not involved in the reversal, but not to features that were not reversed. It is therefore inappropriate to refer to the pigeons as learning a concept.  相似文献

This article examines the ways in which the linkage between good governance and economic development has originally developed as alegal discussion constrained by the constitution of the World Bank. This normative character of the linkage has subsequently shaped discussions about good governance. It is here argued that this tends to lead these discussions to focus on selective and normative aspects of the interrelations between economic, political and legal-administrative structures and institutions. While the role of law is increasingly acknowledged in more recent debates and policy statements, law tends to be approached from a normative economic or legal perspective that does not provide much insight into the social significance of law. Too little attention is given to anthropological or sociological approaches to legal pluralism in society. These factors combine to detract attention from the fact that governance issues in reality deal withbad rather than with good governance. Franz von Benda-Beckmann is professor in the department of Agrarian Law of the Agricultural University Wageningen and teaches on law and rural development in Third World states and anthropology of law. He holds a doctorate in law and aHabilitation in anthropology. His primary research interests are issues of property rights and social security in rural development, legal pluralism and legal anthropological theory. This is a revised version of a paper presented in the 1993 RAWOO (Advisory Council for Scientific Research in Development Problems) lecture series.  相似文献

Gegen einheitswissenschaftliche Nivellierung sind Grundlagen-, Natur- und Kulturwissenschaften zu unterscheiden (weniger als Unterschied von Gegenständen als von Fragestellungen und Vorgehensweisen). Zu den Kulturwissenschaften gehören die historisch-hermeneutischen Disziplinen, und zwar als handlungsverstehende Wissenschaften unter erschwerten Bedingungen. Die Geschichtswissenschaft soll die verborgenen Gründe und Zwecke vergangener Handlungen aufklären, die Textwissenschaften in Form problematischer Texte vorliegende Sprachhandlungen. Texte können in verschiedener Hinsicht problematisch sein: für ein Verstehensinteresse an begründeten Behauptungen oder an subjektiver Bekundung (in selbstdarstellender oder motivierender Absicht). Entsprechend ist hier methodisch zwischen apophantischer und ästhetischer Texthermeneutik zu unterscheiden. Ziel aller historisch-hermeneutischen Fächer sollte kritische Gegenwartsorientierung sein.  相似文献
