对一份文件最早制成时间的检验一直以来都是全世界文检界的难题之一。核实可疑文件的制成时间没有统一的方法,目前主要通过对纸张、墨迹、打字机、复印机、打印机、传真机、印刷品,以及笔迹和签名等因素的检验来确定一份文件的制成时间。文件检验人员需要充分利用他们手中的文件的内容及文件周边信息所反映出来的条件和材料,进而得出结论。  相似文献

In this article we incorporate notions of the fairness of sanctionsinto the standard model of public enforcement. When both theprobability and magnitude of sanctions may be varied, the usualsolution involves a very high sanction and a relatively lowprobability of enforcement if individuals are risk neutral.When the issue of fairness is added to the analysis, the optimalsanction generally is not extremely high because such a sanctionwould be seen as unfair. The optimal probability of imposingsanctions may be higher than in the usual case (to offset thelower sanction) or lower than in the usual case (because thelower sanction reduces the effectiveness of enforcement).  相似文献

Unmet mental health need is a significant problem for adolescents. Although stigma is identified as a major barrier to the use of mental health services among youth, there is limited research on this topic. In-depth interviews (n=57) among a sample of 8th grade students in a suburban, mid-Atlantic community portray adolescent mental health attitudes and how these views are shaped. Satisfactory personal experiences with mental health services as well as accurate mental health knowledge contribute to positive mental health attitudes among teens. The anticipation of negative responses towards mental health care-seeking from family members, peers, and school staff are key factors in teens’ comfort and willingness to address mental health concerns. The research provides critical information on the factors that contribute to the development of stigma and emphasizes the need to address stigma in youth mental health education, programs, and treatment plans. Authors are affiliated with the Johns Hopkins Bloomberg School of Public Health, Department of Population and Family Health Sciences. Dr. Chandra has a background in adolescent health, and is particularly interested in improving the accessibility and appropriateness of youth mental health services and involving young people in the translation of research into practice. Dr. Minkovitz is interested in improving preventive service delivery, enhancing quality of care, and understanding maternal factors that influence children’s receipt of health care  相似文献

Normative deliberative theory has contributed much to an understanding of ideal procedural standards, but there is considerable uncertainty regarding the appropriate nature of desired deliberative outcomes. In this paper we identify two inter‐related concepts of meta‐consensus and inter‐subjective rationality as outcomes that an authentic deliberative process ought to produce. Importantly, these deliberative ends are consistent with ideal deliberative procedure. They are also empirically tractable, where preference transformation can be described in terms of underlying values, and judgments. Methods for assessing deliberative ends are provided and demonstrated using a case study.  相似文献

This research examined the “mental health literacy” of adolescents concerning eating-disordered behavior. A vignette describing a fictional 16-year old female meeting diagnostic criteria for bulimia nervosa was presented to 522 female high school students, followed by a series of questions concerning treatment of and treatment-seeking for the problem described. Results indicated that primary care practitioners, mothers and close female friends were most highly regarded as potential sources of help. Self-help interventions, including the use of vitamins and minerals, were also highly regarded, whereas participants were less positive about the benefits of mental health specialists and ambivalent about the use of anti-depressant medication. Most participants believed that the problem described would be difficult to treat, and that relapse was likely even given appropriate treatment. An additional finding of note was that among participants with a high level of eating disorder symptoms (n=36, 6.9%), recognition of an eating problem was poor. We conclude that beliefs likely to be conducive to low and/or inappropriate treatment-seeking for eating problems may be common among adolescent girls. In addition, the findings suggest that prevention programs for the eating disorders need to target not only at-risk individuals, but also individuals in their immediate social environment.  相似文献

The Social Logic of Politics places social learning at the center of political choice. People develop their political preferences, knowledge, values, perceptions of ability, and decisions about political behavior in interactions with others, usually members of their social circles. Political attitudes and goals are not derivatives of exogenous economic preferences. They are not the results of careful calculations, in which optimization of personal needs guides the mode of reasoning. This theoretical stance draws sustenance from recent work across the social science, even as it harkens back to established, if neglected principles of political analysis. My thanks to Rüdiger Schmitt-Beck for his encouragement and for the critical comments of several anonymous referees and to Josip Dasović and Jennifer Fitzgerald, my co-authors of Partisan Families: the Social Logic of Bounded Partisanship in Germany and Britain (Zuckerman et al. 2007). Material from that book appears in this essay.  相似文献
