Osteoporosis and long-term androgen suppression in the treatment of paraphilias has been documented with surgical castration and the use of gonadotropin-releasing hormone agonists. The literature has suggested that the use of cyproterone acetate (CPA) may be protective against osteoporosis, although there are case reports of osteoporosis in men treated with CPA. This pilot study represents a case series of seven patients diagnosed with severe paraphilias and treated with CPA, leuprolide, or surgical castration. Two of the four patients treated with CPA developed significant osteoporosis, while the other two had normal bone density studies. The remaining three patients, one treated with leuprolide and two with surgical castration, had osteopenia. Based upon the current literature, the finding of significant osteoporosis in two of four patients treated with CPA, but not those treated with leuprolide or castration, is surprising. Monitoring of all patients treated with long-term androgen suppression for osteoporosis is suggested. 相似文献

The intersection of a high‐tech product with 20th century laws that would have inadvertently restricted its use provides an interesting case study in issues management. The authors describe how using ‘high‐tech?high‐touch’ as a technique for public policy change, as well as employing other traditional issues management tools, enabled significant success in achieving the company's public policy goals. As a result of this proactive issues management approach, the high‐tech SegwayTM Human Transporter (HT), a low‐speed self‐balancing, electrically powered, two‐wheeled personal mobility device (Figure 1) is permitted to operate freely in a significant part of its potential market area.

Gender Differences in Rates of Depressive Symptoms Among Low-Income,Urban, African American Youth: A Test of Two Mediational Hypotheses 总被引:3,自引:0,他引:3
Grant Kathryn E. Lyons Aoife L. Finkelstein Jo-Ann S. Conway Kathryn M. Reynolds Linda K. O'Koon Jeffrey H. Waitkoff Gregory R. Hicks Kira J. 《Journal of youth and adolescence》2004,33(6):523-533
The present study tested for gender differences in depressive symptoms in a sample of 622 low-income, urban, African American adolescents. Results indicate that adolescent girls in this sample were significantly more likely to endorse depressive symptoms than were boys. To examine possible explanations for this gender difference, 2 variables were tested as mediators of the relation between gender and depressive symptoms: (1) interpersonal stressors and (2) ruminative coping. Results indicate that ruminative coping, but not interpersonal stressors, mediated the relation between gender and depressive symptoms in this sample. Possible explanations for these findings, in light of the common and unique experiences of low-income, urban youth of color, are explored. 相似文献

Parents may wait to talk to their teens about sexuality until they believe their child is in a romantic relationship. To examine this, telephone surveys were conducted with 1069 parents of adolescents. Measures assessed parents’ perception of teens’ romantic involvement and parent-child communication about several sexuality topics. Multivariable regression models determined the odds of talking about each topic among parents who reported their teen had been in a romantic relationship compared to those who did not. Most parents reported talking at least a moderate amount about some sex-related topic. Parents who believed their teen had been romantically involved were more likely to have discussed most of the topics examined here (ORs=1.64 – 2.56). For some topics, associations were more pronounced among parents of younger teens. Findings suggest that parents may miss important opportunities to influence behavior, and should initiate conversations about sexuality before they believe their child to be romantically involved.Assistant Professor at the University of Minnesota.

Time spent in freely chosen leisure activities offers a distinct developmental context that can support positive youth development; however this potential for growth depends in part on adolescent interest and engagement in their free time activities. Research indicates that many adolescents report experiencing boredom, instead of interest, in their free time. This study utilized longitudinal data from 354 rural middle school students to investigate how parenting practices and adolescent motivational styles influence adolescents’ experience of interest in their free time. Findings indicated that adolescent self-regulated motivation and parental knowledge related to the free time context were positively associated with experiences of interest, while adolescent amotivation and parental control were negatively associated with interest in free time. The effect of parental knowledge and parental control on adolescents’ experiences of interest was mediated by adolescent motivational styles. These results were similar across grade level and gender. Implications for interventions promoting positive youth development are discussed.

The objectives of the study were as follows: (1) to determine the accuracy of psychiatrists' concepts of the self-image of healthy and disturbed adolescents, and (2) to examine the effects of psychiatrists' gender, experience, and specialization on the accuracy of these concepts. Toward this end, eighty-four psychiatrists completed a modified Offer Self-image Questionnaire as they believed a mentally healthy 15-year-old of their gender would respond. These responses were compared to those of 140 nonpatient 15-year-olds. Sixty-one psychiatrists completed the questionnaire as they believed a disturbed 15-year-old of their gender would respond. These responses were compared to the responses of 70 psychiatric inpatient 15-year-olds of the same diagnosis. The results were that psychiatrists had a more accurate concept of normal adolescents' self-image than was found in 1981. However, their view of the self-image of disturbed adolescents was more psychopathological than the disturbed adolescents viewed themselves. Psychiatrists' gender, number of years postresidency, and type of training had no effect on the accuracy of the psychiatrists' concepts. The results demonstrate that while psychiatrists work with disturbed adolescents, they have a more accurate perception of the self-image of normal adolescents. This can effect the diagnosis and treatment of adolescent patients.Presented on May 24, 1994, at the annual meeting of the American Psychiatric Association, Philadelphia, Pennsylvania.Received M.D. from Rush Medical College.

The Family-of-Origin Scale (FOS) is a recently developed 40-item instrument originally designed to assess adults' perceptions of the family in which they were raised. A modified version of the FOS has shown promise for assessing adolescents' perceptions of the extent to which their family fosters autonomy and intimacy. The current study involved administration of the FOS to a large sample of adolescents currently residing with their family of origin. Confirmatory factor analysis supports the scale's original 13 theoretical constructs and establishes factorial validity. Follow-up hierarchical tests indicate the current confirmatory model provides a significant refinement over other plausible models proposed by several different authors finding a similar unitary factor employing exploratory factor analyses. 相似文献

The information sector, delineated as encompassing activities associated with the production and dissemination of information goods and services, is recognised as a dynamic growth sector in developed as well as newly-industrialising countries. Using an input-output methodology, this paper attempts to measure the magnitude and assess the economic impact of the information sector in Singapore. The results are found to be favourable although a number of caveats may be raised regarding its apparent import dependency and foreign exchange earning capability, which has turned from positive to negative over the ten-year period 1973–83. Other issues are also raised concerning the institutional framework, both domestic and international, necessary to support the sector both efficiently and flexibly. Policy implications are drawn from the results of the input-output analysis to consolidate and reinforce current policies to promote information technology in Singapore. 相似文献

In the past, pattern disciplines within forensic science have periodically faced criticism due to their subjective and qualitative nature and the perceived absence of research evaluating and supporting the foundations of their practices. Recently, however, forensic scientists and researchers in the field of pattern evidence analysis have developed and published approaches that are more quantitative, objective, and data driven. This effort includes automation, algorithms, and measurement sciences, with the end goal of enabling conclusions to be informed by quantitative models. Before employing these tools, forensic evidence must be digitized in a way that adequately balances high-quality detail and content capture with minimal background noise imparted by the selected technique. While the current work describes the process of optimizing a method to digitize physical documentary evidence for use in semi-automated trash mark examinations, it could be applied to assist other disciplines where the digitization of physical items of evidence is prevalent. For trash mark examinations specifically, it was found that high-resolution photography provided optimal digital versions of evidentiary items when compared to high-resolution scanning. 相似文献
