This paper discusses ten lessons learned since 1989 about handling allegations of scientific misconduct involving biomedical
and behavioral research supported by the U. S. Public Health Service.
An earlier version of this paper was presented at a symposium, Scientific Misconduct: An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998.

多层线性模型在纵向研究中的运用 总被引:13,自引:0,他引:13
纵向研究中传统统计技术主要是重复测量的方差分析和多元回归分析,但是这两种技术存在一些局限性,不能合理而充分地解释纵向研究资料。近年来出现的多层线性模型能够更有效地利用纵向数据。为促进多层线性模型在纵向研究中的运用,简要论述了传统统计技术的局限,介绍了多层线性模型的原理及其在纵向研究中的作用,以一组模拟数据为例对多层线性模型中各种参数在纵向研究中的含义进行了详细讨论,对于纵向研究中运用多层线性模型时须注意的问题提出了建议。 相似文献

In recent years, the field of community psychology has given considerable attention to how research and evaluation methods should be designed to support our goals of empowerment and social justice. Yet, as a field, we have given much less attention to whether the use of our methods actually achieves or supports our empowerment agenda. With the primary purpose of beginning to establish the norm of reporting on the impacts of our methods, this paper reports on the findings from interviews of 16 youth and adults who had participated in one participatory evaluation method (Photovoice). Two specific questions were examined: (1) What is the impact of participating in a Photovoice effort; and (2) How does the method of Photovoice foster these impacts? Overall, participants noted that they were significantly affected by their experiences as photographers and through their dialogue with neighbors during Photovoice group sessions. Impacts ranged from an increased sense of control over their own lives to the emergence of the kinds of awareness, relationships, and efficacy supportive of participants becoming community change agents. According to participants, Photovoice fostered these changes by (a) empowering them as experts on their lives and community, (b) fostering deep reflection, and (c) creating a context safe for exploring diverse perspectives. The implications of these findings for the science and practice of community psychology are discussed. 相似文献

A review of the literature and ethnographic data from Australia, Canada, New Zealand, the United States, and the United Kingdom on the research ethics review process suggest that moral panics can become triggers for punctuated equilibrium in the review process at both the macro and microlevel, albeit with significantly different levels of magnitude and impact. These data suggest that neither the development of the ethics review process nor the process itself proceeds gradually, but both are characterized by periodic major shifts evoked by particular events or situations that result in varying levels of moral panic. One way to deal with this moral panic is to increase the regulation of research and the depth or intensity of the scrutiny of applications under ethics review. Moral panics at the macrolevel influence those at the microlevel and, if the moral panic evoked at the local or microlevel is not satisfactorily resolved, it will evoke action at a higher level. Understanding the evolution of research ethics review processes from this perspective might help make actions by ethics committees and policy makers more understandable and help explain why attention to research ethics are heightened at particular points in time. It may also provide a basis for developing recommendations for adaptations to the ethics review process and policy at both the local and macrolevel. 相似文献

This paper examines the role of trust and the concept of access as they affect the relational context in which community research, and research with refugee communities in particular, is conducted. Sociologist Irving Goffman's metaphor of frontstage and backstage behavior is used to illustrate the complexity and importance of developing of relations of trust, and thereby gaining "backstage" access, in communities that are generally closed to outsiders. It is argued that gaining authentic ("backstage") access to refugee communities, as well as other communities that have developed a self-protective insularity, is essential if we are to gather data that accurately reflect the actual beliefs, feelings, and experiences of community members. The paper then examines the puzzling lack of discussion regarding issues of trust, access, and the relational context in the literature on refugee mental health. Explanations for this apparent inattention are sought in the influence of the prevailing scientific paradigm that guides most research with refugees, and that shapes the values of the field's "gatekeepers," the editors and reviewers of scholarly journals. Throughout the paper, key points are illustrated with examples drawn from the author's research with refugees from Guatemala, Bosnia, and Afghanistan. 相似文献

The current article is an analysis of the research represented in American Journal of Community Psychology (AJCP) from 1993 to 1998, including a comparison to two previously published analytic reviews by Lounsbury et al. (J. W. Lounsbury, D. S. Leader, E. P. Meares, & M. P. Cook, 1980) and Speer et al. (P. Speer, A. Dey, P. Griggs, C. Gibson, B. Lubin, & J. Hughey, 1992), respectively. Observed trends are examined with references to major epistemological frameworks and methods used to define community psychology. Four guiding principles were examined to determine the representation of the epistemological frameworks of the articles published in the journal. The frameworks include social action, human diversity and cultural relativity, person–environmental fit, and methodological procedures. The results document the transition of community psychology from its early beginnings to an independent field conducting research consistent with the values articulated at the Swampscott Conference. This paper also comments on how well, after three decades of publication, the journal has served as a vehicle for improving community life. 相似文献

I ask whether weapons research is ever justified. Weapons research is identified as the business of the engineer. It is argued
that the engineer has responsibility for the uses to which the tools that he designs can be put, and that responsibility extends
to the use of weapons. It is maintained that there are no inherently defensive weapons, and hence there is no such thing as
‘defensive’ weapons research. The issue then is what responsibilities as a professional the engineer has in regard to such
research. An account is given to ground the injunction not to provide the means to harm as a duty for the engineers. This
account is not, however, absolutist, and as such it allows justifiable exceptions. The answer to my question is thus not that
weapons research is never justified but there must be a strong assurance that the results will only be used as a just means
in a just cause. 相似文献

The purpose of the study was to test if design and research methods of studies predict outcome results of bulimia nervosa. Fifty-seven articles on outcome of bulimia nervosa were found through MEDLINE and PSYCHINFO databases and 25 were included in the statistical analysis. Percentages of patients with a good outcome ranged from 24% to 74% with a mean of 51.1%. The variables best predicting outcome were time to follow-up and number of symptoms evaluated in definition of good outcome whereas dropout, design of studies, treatments, and sample characteristics did not predict significantly. The implications of these findings are discussed. 相似文献
