Physical Inactivity,Obesity, and Type 2 Diabetes: An Evolutionary Perspective     

S. Boyd Eaton  Stanley B. Eaton 《Research quarterly for exercise and sport》2017,88(1):1-8

Physical inactivity (and unhealthy nutrition) has distorted body composition and, in turn, reordered the proportions of myocyte and adipocyte insulin receptors. Insulin acting on adipocyte receptors produces less glucose uptake than does comparable interaction with myocyte receptors. Accordingly, in individuals with disproportionate muscle/fat composition, any given glucose load requires greater-than-normal pancreatic insulin secretion for adequate disposal. This hyperinsulinemia then becomes the leading cause of type 2 diabetes (T2DM) as insulin-sensitive tissues become desensitized. Because T2DM is rooted in potentially reversible lifestyle factors, rather than focusing on the intricacies of glucoregulation at the molecular level and on testing new drugs to control blood sugar, this article calls for a new prevention and treatment paradigm, in which exercise and weight control are essential and for which an inexpensive and acceptably accurate measure of body muscle and fat proportions is needed.  相似文献   

Effect of Active Lessons on Physical Activity,Academic, and Health Outcomes: A Systematic Review     

Rosemarie Martin  Elaine M. Murtagh 《Research quarterly for exercise and sport》2017,88(2):149-168

Purpose: The purpose of this study was to conduct a systematic review of classroom-based physical activity interventions that integrate academic content and assess the effectiveness of the interventions on physical activity, learning, facilitators of learning, and health outcomes. Method: Six electronic databases (ERIC, PubMed, Google Scholar, Science Direct, Cochrane Library, and EMBASE) and reference lists were searched for English-language articles, published January 1990 through March 2015, reporting classroom-based interventions that deliberately taught academic content using physically active teaching methods for at least 1 week duration, with physical activity, health, learning, or facilitators-of-learning outcomes. Two authors reviewed full-text articles. Data were extracted onto an Excel spreadsheet, and authors were contacted to confirm accuracy of the information presented. Results: Fifteen studies met the inclusion criteria. Six studies reporting on physical activity levels were found to have medium-to-large effect sizes. All 4 studies reporting learning outcomes showed positive effects of intervention lessons. Teachers and students were pleased with the programs, and enhanced on-task behavior was identified (n = 3). Positive effects were also reported on students’ body mass index levels (n = 3). Conclusions: Physically active academic lessons increase physical activity levels and may benefit learning and health outcomes. Both students and teachers positively received and enjoyed these teaching methods. These findings emphasize the need for such interventions to contribute toward public health policy.  相似文献

Rajnikant in Japan: Indian “superstardom” and low value markets     

S.V. Srinivas 《Inter-Asia Cultural Studies》2013,14(4):615-634

This paper draws attention to some questions thrown up by the increased circulation of mass-produced cultural commodities sourced from Asia in the relatively new markets of the region. Juxtaposing the short-lived success of the Indian star Rajnikant in Japan in the late 1990s and the unsuccessful attempt to promote Korean films in the Indian theatrical circuits a decade later, the paper argues that in spite of their considerable differences both instances foreground the difficulties cultural industries of Asia have in generating revenues in the region's markets. The paper goes on to elaborate on a model of stardom, exemplified by Rajnikant, which has evolved as a direct response to the challenges posed by low value markets.  相似文献   

Facilitating Intercultural Communication in Parent–Teacher Conferences: Lessons From Child Translators     

Inmaculada M. García–Sánchez  Marjorie Faulstich Orellana  Megan Hopkins 《Multicultural Perspectives》2013,15(3):148-154

In this article Abraham Lincoln is considered as an alternative to the usual type of patriot's hero. He reminds us of our great historical failings. He remains a figure of controversy, a national hero in only some corners of society. He is the heroic President who serves as the first compassionate defender of the downtrodden, and he is a hero in those subcultures as well. Lincoln's treatment in the movies is discussed, focusing particularly on the recent movie Lincoln. Lincoln is seen as a match for the usual movie hero. His famous immunity to casual treatment in popular culture is discussed as well.  相似文献   

(Re) Claiming Native Youth Knowledge: Engaging in Socio-culturally Responsive Teaching and Relationships     

Tiffany S. Lee  Patricia D. Quijada Cerecer 《Multicultural Perspectives》2013,15(4):199-205

This article reveals Native youth perspectives on socio-culturally responsive education. The authors draw on two studies conducted in the Southwest among Navajo and Pueblo students. Youth convey the importance of meaningful, reciprocal, and transformative learning experiences and relationships at school. The article ends with suggestions for creating a socio-culturally responsive school environment.  相似文献
