In mid‐June 2009, the Obama administration dissolved the President's Council on Bioethics (PCBE), a group established by President George W. Bush in August 2001 and whose nearly eight‐year life was marked from beginning to end by controversy. While some will regret the PCBE's passing, others will regard the Council as a failed experiment in doing public bioethics.  相似文献

In Evangelium Vitae Pope John Paul II calls for a renewal of culture to combat the culture of death. He criticizes various aspects of a pluralistic, liberal society—a type of society that he claims is based on moral relativism and a view of democracy that becomes a substitute for moral law. He maintains that such a view trivializes moral choice. In this essay I argue that John Rawls's notion of a liberal society as an overlapping consensus of comprehensive doctrines can avoid relativism while allowing for reasonable debate among opposed positions. While Rawls maintains that comprehensive doctrines, including religions, should employ a form of public reason that is not a unique feature of any one comprehensive doctrine, I argue that this requirement is too strong. One is often justified in appealing to features of comprehensive doctrines other than one's own, features that are unique to the doctrines themselves. Such an appeal does not pretend to be neutral as public reason would seem to be. In the final section of the paper I discuss some suggestions made by the Pope regarding actions in civil society that are independent of debates about legal change and suggest some ways in which they might contribute to desired cultural transformation.  相似文献

A quasi-experimental replication of an intervention for promoting tobacco control policies in Northwest Indian tribes is described and the process of intervention including issues of collaboration among research institutions and Indian organizations is discussed. The policy intervention was evaluated using a pretest-posttest design wherein 20 tribes that had served as wait-list controls now received the intervention. The intervention comprised a tribal representative attending a kickoff orientation; follow-up visits to the tribes; distribution of tobacco policy workbooks; and phone call consultations. Policy status and stringency were assessed by means of telephone interviews with two key contacts per tribe, and by a count of enacted policies. There were significant pre-post changes in the primary outcome measure, a composite summary score of tobacco policy stringency, and changes were also reflected in enacted policies. The intervention effects observed were similar to those found in the prior randomized trial and suggest a robust, disseminable intervention. Much of the success achieved was attributed to the role of an Indian organization in planning the project and implementing the intervention and evaluation protocols.  相似文献

The popularity, and subsequent ambiguity, in the use of the term “empowerment” has created an even greater need for reassessment in the applied context than in the theory and research literatures. This paper outlines some of the areas of community, organizational, and societal level social intervention and policy ostensibly based on the concept of empowerment. These include neighborhood voluntary associations (for environmental protection, community crime prevention, etc.), self-help groups, competence-building primary prevention, organizational management, health care and educational reforms, and national and international community service and community development policies. Issues in applying social research to community organizations and to legislative and administrative policy making are reviewed. Ten recommendations are offered, including the value of a dialectical analysis, for helping researchers and policy makers/administrators make more effective use of empowerment theory and research. Humpty Dumpty: “When I use a word, it means just what I choose it to mean neither more nor less.” King of Hearts: “If there's no meaning in it, that saves a world of trouble, you know, as we needn't try to find any.”—Lewis Carroll Portions of this paper were first presented in the program “Empowerment Theory, Research and policy” at the Biennial Conference on Community Research and Action, Williamsburg, Virginia, June 18, 1993. The author thanks Barbara B. Brown, Jo Ann Lippe, Ken Maton and his students, David V. Perkins, Marc A. Zimmerman, and the anonymous reviewers for their very helpful comments on earlier drafts.  相似文献

The current rationale for Freedom of Speech is entangled in Enlightenment assumptions about the relationship of discourse to public life. This article critiques those assumptions and proposes an alternative rationale for Freedom of Speech based in assumptions of contemporary rhetorical theory.  相似文献

Using an organizational culture framework, this case study examines the critical preconditions necessary for employee empowerment and highlights how the multiple cultures within one public bureaucracy differently impacted their implementation. SERVE, a large human service organization, initiated an employee empowerment program that contradicted and thus collided with many elements of its overall organizational culture. Despite the best intentions of the organizational leaders, upper management support, and opportunities for participatory decision making, the organization could not foster the critical preconditions needed for employee empowerment. Leaders had difficulty expanding the employees' power and promoting member inclusion. Concurrently, most employees rejected these new opportunities for control and distrusted the leader's intentions. Yet, despite the widespread rejection of these empowerment initiatives, most employees described their work lives as empowering. The role the local site subculture played in promoting employee empowerment is examined. We discuss how a localized (vs. system-wide) empowerment endeavor may be a more appropriate and feasible focus for public bureaucracies seeking to initiate greater staff empowerment. Particular attention is paid to the interaction between individuals and their environments, and how this interaction affects the empowerment process.  相似文献

An experiment was performed to assess the role of expectations in psychosocial contrast effects. Subjects were initially presented with a series of word definitions that were either high or low pathology; their task was to indicate those definitions that had been produced by schizophrenic (vs nonschizophrenic) patients. After this “induction” series, subjects were presented with a common “test” series that included both definitions and handwriting samples; they evaluated the degree of psychopathology that was implied by each item. Some subjects were required to state their expectations in connection with the test items. First they attempted to guess the percentage of schizophrenics in the overall test series; second, before being presented with each test item, they guessed whether the patient in question was (or was not) schizophrenic. Subjects' expectations were consistent with the induction series to which they were assigned; those assigned to the high-pathology induction expected the test series to include more schizophrenic patients than those in the low-pathology group. Nonetheless, despite these expectations, subjects showed a contrast effect in their evaluations of the test definitions (but not in evaluating the handwriting samples). That is, subjects from the low-pathology induction group rated the test definitions as being more pathological than did those in the high-pathology condition. Within-group correlations indicated that the subjects' expectations were directly related to subsequent judgments. A two-path model is discussed, relating (a) the respondents' induction group assignment, (b) his/her expectations, and (c) subsequent test judgments.  相似文献

The effect of an instructional package on public-speaking behaviors was analyzed in two experiments. The instructional package was designed to teach public-speaking trainees to look at the audience, make gestures, and perform a number of speaking behaviors. The results of Experiment I, with a university student serving as the trainee, showed that the percentage of each category of public-speaking target behavior increased only after the instructional package was introduced for that category. The results of Experiment 2, with three low-income paraprofessional staff members of a neighborhood service center serving as trainees, showed that the percentage of target behaviors increased after the instructional package was introduced for the respective trainee. Audience ratings of public-speaking performance were correlated with direct observations of target responses. All trainees showed marked improvements in audience ratings from pretraining to posttraining. This study demonstrated an effective procedure for training public-speaking behaviors.  相似文献

In the first experiment, after establishing baseline composition rates in each classroom, timing (announcing time limits) and feedback (student self-scoring) were introduced followed by the introduction, removal, and reintroduction of public posting of highest scores. Timing and feedback improved story writing performance and public posting of highest scores improved performance even further in both classrooms. Teacher praise produced further improvement in one classroom but had no effect on performance in the other. Changes in on-task behavior paralleled changes in writing rate. Comments made by children concerning their own work or work of their peers were recorded throughout the experiment. Although the baseline rate of performance comments was almost zero, the introduction of each variable markedly increased the rate of performance comments. In the second experiment, baseline rates on reading and language exercises were established in a fifth-grade classroom. The entire performance feedback system was introduced on a multiple baseline across the two behaviors and then removed during the final phase of the experiment. Introducing the system improved performance on both tasks. These results further increased the generality of some of the findings of the previous experiment and of previous research on the efficacy of the experimental package of timing, feedback, public posting, and praise.  相似文献

When considering the persuasive characteristics and prospective influences of Darwin-skeptic mass media, uncertainties remain about how to reciprocally promote evolutionary theory to skeptical audiences. This study aims to improve evolution advocacy by translating some of the most successful methods of science endorsement to Evolution Wars contexts. In particular, strategies used to address vaccine hesitancies and enhance immunization uptake policies are reinterpreted for those seeking to improve pro-evolution communications to religious publics. What results are three recommendation categories described as General Guiding Principles, Proximate Interventions, and Auxiliary Interventions.  相似文献
