Prior research links social support with several positive health outcomes. However, less is known about the association between social support and Type 2 diabetes risk factors, such as glycemic control. This study uses a nationally representative sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the relationship between social support and glycated hemoglobin A1c (HbA1c) levels. The data were analyzed through hierarchical logistic regression. Results indicate an inverse relationship between elevated HbA1c levels and individuals’ satisfaction with their partners’ daily interactions. Implications include the possibility of reducing Type 2 diabetes risk through communication interventions highlighting the importance of maintaining positive daily interactions. 相似文献

This paper explores the rise of programs in television instruction in the USA during broadcasting’s postwar expansion period. Beginning in professional schools, television training entered the university first through extension school courses, then in full degree programs. This transition to institutions of higher learning entailed key shifts in demographics, pedagogical orientation, and legitimation strategies, while embroiling television in larger struggles over the shifting boundaries of the postwar humanities. Studying the education of early television workers, I argue, raises key questions about processes of worker professionalization vital for developing research on media industries and media labor. 相似文献

Background: Prolonged strenuous exercise has a profound effect on cardiac function. The right heart may be more susceptible to this imposition; yet, right-sided chest leads have not been utilised in this setting. Methods: Thirty highly trained athletes at the 2014 Western States 100-mile Endurance Run from Squaw Valley to Auburn, California (body mass 68?±?12?kg, age 45?±?10?years, 57?±?15?miles per week) were recruited for the study. Pre- and post-race, a right-sided 12-lead ECG was obtained and data were extracted for P, R and S waves, J point, ST segment and T wave amplitude. Data were compared using Students T-test and statistical significance set as P?.05. Results: There was a significant increase in P wave amplitude (29%) and QTc interval (4%) pre- to post-race from standard 12-lead ECG. From the right-sided12-lead ECG, a 23% (P?=?.01) and 38% (P?=?.03) increase in J point amplitude in V1R and V2R and a 22% (P?=?.05) increase in ST segment integral in V2R and V3R were evident. T wave inversion was evident in leads V2R–V6R in 50–90% of athletes, respectively. Close examination revealed marked heterogeneity in individual ECGs. Conclusions: Completion of a 100-mile ultra-marathon resulted in significant changes in the right-sided ECG alongside more marked responses in specific individuals. P wave, ST segment and T wave changes post-race are indicative of acute exercise-induced right heart electrical adaptation. 相似文献

This study replicates and extends research on college students’ sexual possible selves by longitudinally examining their sexual expectations, fears, and behavioral strategies at the beginning and end of the first semester in college. Open-ended responses were collected at two time points (T1, N?=?78; T2, N?=?40) and were analyzed using directed content analysis. First semester students’ salient expectations and fears focused on abstinence, interpersonal relationships, quantity, conditional sex, decreasing/avoidant behaviors, and fears related to sexual health/well-being, sexual assault/coercion, self-focus, and increased sexual risk at both T1 and T2. However, two new themes emerged at T2: maintain (expected) and partner-focus (feared). At both time points, behavioral strategies included abstinence, making opportunities, restricting boundaries, sexual health/well-being, thoughtful/informed decisions, and self-assertion/protection. Quantitative frequency comparisons were also conducted to examine changes in the prevalence of the reported categories and indicated shifts in salient expectations, fears, and strategies across the first semester. Implications for sexual education are discussed. 相似文献

Air pollution is one of the environmental influences that degrade cultural heritage objects situated indoors. Other essential influences, such as temperature, relative humidity, and light are often well monitored. The presence of air pollutants is less often measured or included in risk assessment. The MEMORI® technology presented in this paper was developed as a tool for easy measurement and assessment of the general risk of degradation of heritage objects situated indoors due to indoor exposure to air pollutants. MEMORI dosimetry was performed in locations belonging to English Heritage and Tate (both located in London) and the National Archives of Norway in Oslo, to assess air quality. The related damage risk for collection objects and the protection offered by display and storage designs was assessed. A high level of acidic effect was observed inside a number of showcases, and a high level of oxidizing effect was observed in some room locations. Relatively simple mitigation measures, such as constructing tightly sealed showcases using low emitting materials, installing active carbon absorbing media inside a ‘microclimate’ frame, and using cardboard storage boxes for paper, significantly improved air quality. Overall, implementation of such measures is likely to improve the preservation of objects and reduce conservation costs. 相似文献

The issue raised by the authors in this article question why studio art continues to be ignored as a site and source for research in art education. The necessity of the field to be able to participate within the research community in addressing cultural, social, educational and political concerns is acknowledged. It is argued, however, that the exclusive use of methods of inquiry that align with the conventions of social science research has been done at the expense of fully appreciating the capacity of artistic research undertaken in studio contexts. This tendency is especially prevalent in doctoral research in higher education. Three accounts of dissertation research are given that incorporate studio activity as a central agency of inquiry in conceptualising and theorising issues. Each highlights the capacity of art practice to reveal insights that are a consequence of what the researcher did in the studio setting as issues, ideas and interpretive stances emerged, and problems were re‐conceptualised. What is different in these accounts from more mainstream approaches to research is the readiness to accept that constructing new knowledge is a creative and critical process. 相似文献

Social class is an important issue that must be taken into consideration when examining crime and criminal behavior in the United States. Social class is often viewed as a critical factor that influences the motivation to commit criminal activities. This article describes an interactive exercise that helps students better understand how social class may influence deviant and/or criminal behavior as a response to wanting to maintain status quo (particularly those in middle to upper class levels), economic hardships (that may occur at various class levels), the lack of social power, income inequality, or the lack of resources. 相似文献
