Purpose: This study examined whether rural women, who had a high prevalence of prehypertension and hypertension upon enrollment in a wellness program, would also have a high prevalence of other cardiovascular disease risk factors such as low fitness and/or dyslipidemia. Methods: Data were analyzed from 225 rural women, ages 50-69, enrolled in a healthy eating and activity clinical trial. Cardiovascular health histories, fitness measures, blood pressure, and fasting blood serum samples were collected following standardized protocols at rural research offices. Chi-square and MANOVA were performed to examine differences in health characteristics, lipids, and fitness across blood pressure categories. Results: Fitness indicators of estimated VO2max, 1-mile walk time, and resting heart rate differed between the blood pressure groups, with those in the prehypertensive and hypertensive groups having less desirable profiles than those in the normotensive group. Triglyceride levels of 150 mg/dL or greater, were observed in 36%, 32%, and 16.7% of women who had hypertensive, prehypertensive, and normal blood pressures, respectively. Conclusions: The need for routine blood pressure screenings by practitioners is reinforced by finding that rural women screened via PAR-Q and/or physician clearance had a high prevalence of prehypertensive and hypertensive blood pressures, in addition to low fitness and nonoptimal triglycerides. Practitioners need to provide counselling based on results and refer to other providers as appropriate.Key Words: blood pressure, lipids, fitness, rural women  相似文献

Discussion focuses on those problems caused by the isolation of studies in logic from studies in education. The authors recommend a taxonomic distinction in formal inference‐making routines that has long been recognized in the field of logic. The authors illustrate how this taxonomic distinction can be usefully employed in the classroom to help children think more precisely and to think about thinking more deliberately.  相似文献

Technology plays an integral role in the lives of the majority of the US population. As technology becomes integrated into young people’s lives, questions arise regarding its effects on learning. This exploratory study draws on interviews with students who attend university in the United States to determine how separating students from technology deepens experiential learning. Participants were interviewed following a study abroad course to New Zealand, during which they were disconnected from technologies such as cell phones, the Internet and social media. In the interviews, students discussed their feelings of being disconnected and describe how disconnecting impacted their overall experience. Participants agreed that disconnecting from technology had positive effects on experiential learning and the global experience. Major themes that emerged include students’ enhanced immersion and engagement, the value of disconnection in providing opportunities for personal growth and the difficulty of initial separation from technology as a result of conditioning.  相似文献

美国图书馆的今天:实践、趋势与挑战   总被引:9,自引:0,他引:9  
目前,美国的图书馆一般都订有策略性规划,有自己的人事分类体系,建立了内部切磋交流机制和组织机构,十分重视用户工作。其发展呈现如下一些趋势:越来越多地使用电子服务方式;注重书目的双重作用;大力开展远程教育和原文传递服务;推行馆舍联合使用和采编外包及联合购买,等等。不断变化的形势,也给美国的图书馆提出了新的挑战,如如何处理科技消费问题、经费预算不稳和馆员短缺问题、资源价格高居不下和网上色情问题,等等。  相似文献

The present study describes and compares seating preferences among Taiwanese and American respondents. Using a questionnaire method, seating preferences were obtained for 75 male and 100 female college students from the United Slates, and for 29 male and 54 female teachers of English in Taiwan. Responses were obtained for all possible combinations of sex of interaction partner, location (task or social), and six interpersonal activities. Results were summarized in the form of proportions of respondents choosing each of four possible angles of interaction: corner, opposite, diagonal, and side seating. Comparisons were made using Chisquare tests for independence.In general, results showed that Taiwanese respondents, when compared to Americans, are more likely to prefer side seating and less likely to prefer corner seating. Culture, sex of respondents, and sex of interaction partner interact in influencing preferences. In the United States, seating preferences function to unite males with females and to separate same-sex partners, while the opposite is true in Taiwan. Results are interpreted in terms of implications for intercultural communication.  相似文献

A field study was conducted in Israel to identify emblematic gestures recognized and used by Hebrew speakers. Studies which have identified the emblematic gestures of particular ethnic or national groups are reviewed and criticized. This study seeks to contribute increased rigor and systematology to the identification of particular groups' emblematic gestures.Twenty-six gestures commonly used in classroom interaction were selected for testing. The instrument used was Schneller's form, “Investigations of Interpersonal Communication in Israel.” Subjects included college students, members of YMCA classes for pensioners, and others. On the instrument, subjects noted their recognition and interpretations of the investigator's encoding intentions, their certainty or interpretation and where they learned each gesture.Whereas previous studies of this nature accepted around 70% interpretive agreement among subjects, this study indicates that at least 90% is a more reliable measure by which to label gestures “emblems.” In addition, correlations were tabulated for the effects of subjects' age, ethnicity, years in Israel, certainty about interpretation, and accuracy of interpretation.The findings of this study were: (a) eight gestures were identified as emblems, and three more gestures identified as possible emblems, (b) slightly negative although insignificant correlations were found between increased age, years in Israel, expressed certainty of interpretation and accuracy of interpretation, and (c) natives and subjects from 20–24 years of age tended to have the highest rates of expressed certainty of interpretation as well as accuracy of interpretation.The findings are compared with those of three other studies of Jews' gesturing and differences between the studies are considered. Recommendations include continuing such studies and comparing the results of related projects in order to form a comprehensive picture of particular groups of people.Limitations are discussed. These include: (a) a less than representative sample, (b) lack of a consistent conversational context, (c) potential for distortion in the decoding process, (d) the lack of a unified gesture labeling system, and (e) the possibility of cultural or researcher bias.  相似文献
