Using the United States and Great Britain as a comparative case study, this article employs a historical framework to consider the broad array of social, cultural, political, and economic contexts that led to divergent outcomes in the early development of broadcasting policy. This comparative historical analysis reveals the causal chains formed before the 1920s despite a period of post-war contingency. As a policy option, government control was removed in the United States but stayed in place in Britain after the war. This comparative approach can help to explain policy outcomes and inform modern policy debates.  相似文献

This study examined longitudinal effects of adolescent and parent cultural stress on adolescent and parent emotional well-being and health behaviors via trajectories of adolescent and parent family functioning. Recent immigrant Latino adolescents (Mage = 14.51) and parents (Mage = 41.09; N = 302) completed measures of these constructs. Latent growth modeling indicated that adolescent and parent family functioning remained stable over time. Early levels of family functioning predicted adolescent and parent outcomes. Baseline adolescent cultural stress predicted lower positive adolescent and parent family functioning. Latent class growth analyses produced a two-class solution for family functioning. Adolescents and parents in the low family functioning class reported low family functioning over time. Adolescents and parents in the high family functioning class experienced increases in family functioning.  相似文献

The present study was designed to examine acculturative changes, and their effects on mental health and family functioning, in recent‐immigrant Hispanic adolescents. A sample of 302 Hispanic adolescents was assessed five times over a 2½‐year period. Participants completed measures of Hispanic and U.S. practices, collectivist and individualist values, and ethnic and U.S. identity at each time point. Baseline and Time 5 levels of mental health and family functioning were also assessed. Latent class growth analyses produced two‐class solutions for practices, values, and identifications. Adolescents who increased over time in practices and values reported the most adaptive mental health and family functioning. Adolescents who did not change in any acculturation domain reported the least favorable mental health and family functioning.  相似文献

This article documents the steps taken to assess metadata errors within the IDEALS repository. It describes the workflows established to create accurate and consistent metadata, focusing especially on the batch ingest and retroactive metadata remediation processes. It also seeks to address theoretical issues surrounding the concept of metadata quality.  相似文献

Hormones play an important role in the development and regulation of reproductive function and the menstrual cycle of women. Extremes of body weight tend to affect the homeostasis of the hypothalamo–pituitary–gonadal axis. This cross-sectional study was carried out in 113 women (57 with primary infertility and 56 with secondary infertility) in the age group 20–35 years, presenting for hormonal evaluation of infertility in a tertiary care hospital. After preliminary clinical evaluation, anthropometric indices (height, weight, BMI, waist circumference and waist hip ratio) were measured in all subjects. Fasting blood sample drawn on second/third day of menstrual cycle was analysed for serum luteinizing hormone, follicle stimulating hormone (FSH), prolactin and thyroid stimulating hormone (TSH). Serum FSH levels showed a significant positive correlation with indicators of central obesity (waist circumference and waist hip ratio in both the study groups). In primary infertility, significant positive correlation was also observed between serum FSH levels and other markers of obesity like body weight, hip circumference and BMI. In secondary infertility, serum prolactin and serum TSH levels demonstrated a significant positive correlation with body weight and BMI. Obesity is associated with hormonal derangements which are responsible for infertility. In overweight women with infertility, weight loss should be considered as a first line treatment.  相似文献

Basic factual information about disease is the cornerstone of health promotion and disease prevention interventions. Previous studies have shown that content analysis of the questions asked of service providers can elucidate the information needs of service consumers. Questions asked by individuals at known high risk for HIV infection have not previously been examined. The current study analyzed 944 questions asked by 634 patients receiving HIV‐risk‐reduction counseling services at an urban sexually transmitted infections clinic. Questions were captured from audiotape recordings of risk‐reduction counseling sessions that were subsequently transcribed and content‐analyzed. A total of 49% of clients asked at least one question in their counseling session. Asking counselors questions was not associated with demographic characteristics or AIDS‐related knowledge. Questions were found to fit the AIDS information content structure identified in past research. The most common questions asked by sexually transmitted infection clients concerned condoms and other barrier methods of prevention (15%), HIV symptoms and disease progression (14%) and HIV antibody testing (11%). These results show that many individuals at high risk for HIV infection have substantial information needs, and that basic education about AIDS facts should not be neglected in HIV prevention interventions.  相似文献

The current study is an analysis of public service announcements (PSAs) from an effective safer sex campaign that utilized a sensation-seeking targeting (SENTAR) approach. Two random samples of heterosexually active young adults (sample one N = 1,463, sample two N = 895) viewed different sets of safer sex PSAs on a laptop computer and answered questions about their perceived sensation value and perceived effectiveness. Multiple regression analyses examined the impact of (a) demographic, (b) individual difference, (c) sexual context, and (d) message variables including perceived message sensation value (PMSV) on the perceived message effectiveness (PME) of the PSAs. Results indicated that females, African Americans, condom users, and those with less education viewed the PSAs as slightly more effective than males, Caucasians, non-condom users, and those with more education. PMSV and personal utility emerged as the strongest predictors of PME, even after controlling for all of the aforementioned variables. Implications for further research on PMSV and perceived and actual effectiveness of PSAs are offered.  相似文献

This conceptual paper contributes to the scholarship on life-long learning programs at public universities. It investigates the unique relationship between these institutions and their state, utilizing Ohio as an illustrative example. A review of several university mission statements illuminates the responsibility of these institutions to their older-learner programs. Particular emphasis is placed on Over-60 programs, a university course audit program found in many states. Older learners face many barriers and challenges on college campuses because institutions struggle with limited resources and support for older-learner programs. This paper further encourages dialogue about the benefits of older learner programs.  相似文献
