Leisure time physical activity in Australian women: relationship with well being and symptoms 总被引:5,自引:0,他引:5
This paper explores the association between moderate levels of physical activity (PA) and health benefits in well being and symptoms such as tiredness, back pain, and constipation. Participants in the Australian Longitudinal Study on Women's Health, 14,502 young women (ages 18-23 years), 13,609 middle-age women (45-50 years), and 11,421 older women (ages 70-75 years), answered questions about vigorous and less vigorous exercise (used to determine a physical activity score), well being (SF-36), symptoms, and medical conditions. There were significant associations between the PA score and SF-36 in each cohort. Odds ratios (OR) for a range of symptoms and conditions were lower for women who reported low to moderate activity than for sedentary women, for example, for young women or for constipation = 0.76 (CI, 0.65-0.89), for middle-age women or for tiredness = 0.70 (0.63-0.78). There was no threshold of PA at which health benefits increased significantly. Although cross-sectional, the findings suggest that low-to-moderate levels of exercise are associated with a range of health benefits for women of all ages. These preliminary findings will be followed up during the longitudinal study. 相似文献

The present experiment examined the learning effects of participants self-controlling their receipt of knowledge of results (KR) on all or half of their acquisition trials (50%). For participants who were provided 50% self-control, the first half of their acquisition period consisted of receiving KR on all trials, or according to a faded-KR schedule. Participants practiced a sequential timing task. The results showed that independent of practice condition, participants who self-controlled their KR during the acquisition period demonstrated superior performance compared to the respective yoked conditions in the retention and transfer portion of the experiment. These results extend previous research by suggesting that decreasing the proportion of self-control trials does not compromise learning in a self-controlled context. 相似文献

ABSTRACTThe aim of this study was to systematically review the literature to verify the association between participation in sports (PS) in childhood and adolescence and physical activity (PA) in adulthood. A systematic search was conducted in the following databases: Medline (PUBMED), Web of Science, Scopus, and SPORTDiscus, LILACS and SciELO. All steps of the process followed the recommendations of the PRISMA FlowDiagram. After all the steps of the process, 29 articles were included for analysis. In general, only three of the studies analyzed found no relation between PS in childhood and adolescence and PA in adulthood. However, a positive relationship was found to be weak in only 7% of the studies, a moderate relation in 62% of the studies, and a strong relation in 21%. It was found that higher weekly frequencies of PS; persistence of at least three years of PS and, finally, the highest level of practice and/or competition reached were related to higher levels of PA in adulthood. Thus, it can be concluded that there is a positive association considered moderate to strong between PS in childhood and adolescence and PA in adulthood. 相似文献

Parent Resource Centers: An Innovative Mechanism for Parental Involvement in School Choice Decisions
Hesborn Wao Vanessa L. Hein Roger Villamar Susan Chanderbhan-Forde Reginald S. Lee 《Journal of School Choice》2017,11(3):334-356
This qualitative investigation reports on the use of Parent Resource Centers (PRCs) as a mechanism for parental involvement in public school choice decisions. Interviews with parents and staff at seven PRCs in Florida revealed that PRCs employ multiple strategies to communicate choice information to parents: community-, school- and media-based outreach; outreach to hard-to-reach parents; and collaboration with other agencies. Personalized assistance and provision of choice materials are also highlighted as useful strategies. Results indicate that there is low level of awareness about school choice options among parents and thus clear and consistent communication of choice information is needed. While PRCs hold promise for increasing parental engagement in school choice, structural and systemic barriers to exercising choice decisions such as transportation and collaboration between schools and PRCs should be addressed. Methodologically, this study illustrates the power of triangulating data from parents and PRCs to illuminate our understanding of how parents make choice decisions. 相似文献

This study explores issues related to the tutor’s role when initiating tutoring as an institutional strategy at a conventional university. Based on a pilot tutoring program implemented in four college courses, we investigated the perceptions of instructors, tutors and students regarding the role of tutoring and whether it affected the psychological distance between the different types of participants. The results indicated that instructors’ perceptions of the tutor’s primary role and the psychological distance from the students and the tutors differed from the perceptions of the tutors and the students, perhaps because the instructors perceived tutors as a source of instructor support rather than student support. Implications and suggestions are discussed. 相似文献

Globalization and the evolution of the knowledge‐based economy have caused dramatic changes to the character and functions of higher education in most countries around the world. However, the impacts of globalization on universities are not uniform though business‐like practices have been adopted to cope with competition in the global marketplace. The pressure for restructuring and reforming higher education is mainly derived from growing expectations and demands of different stakeholders in society. In recent years, widespread concerns over widened access, funding, accountability, quality, and managerial efficiency are perceived as the prominent global trends related to university education. Because of the divergent political, social, economic, cultural and historical backgrounds, national/local governments may adopt similar strategies in response to pressures generated from globalization. Nonetheless, through a close scrutiny of the ways that national policies are made, we may find that governments around the globe, particularly in East Asia, have tried to make use of the globalization discourse to address/justify the local policy/political agendas. This paper aims to examine the latest higher education reform initiatives proposed by the Singapore Government, with particular reference to reflect upon how the Singapore Government reforms its university systems in the context of globalization. It is argued that the latest comprehensive review of public university governance and funding brings about a changing role of the government in the regulation, finance and provision of higher education in Singapore and eventually alters the state‐university relationship. 相似文献

In spite of increasing interest in open innovation, discussion about the concept and its potential application to the SME sector has been excluded from mainstream literature. However, given that the argument about the effect of firm size on the effectiveness of innovation is still ongoing, it is worth addressing the issue from an SME perspective. That is the focus of this article, which seeks, firstly, to place the concept of open innovation in the context of SMEs; secondly to suggest the input of an intermediary in facilitating innovation; and finally to report accounts of Korean SMEs’ success in working with an intermediary. The research results support the potential of open innovation for SMEs, and indicate networking as one effective way to facilitate open innovation among SMEs. 相似文献

Based on data collected through a complex survey of science and engineering PhD graduates from a UK research-based university, this paper examines the different types of careers and to what extent different types of competences acquired from doctoral education are regarded as valuable in the different career types. The results show that employment outside the conventional technical occupations is the main destination for the survey respondents. This career type is not only successful at retaining its members, but is also the destination of the other career types. Moreover, different types of competences from doctoral education are regarded as relatively more valuable in different career types: knowledge directly tied to subject areas is regarded as more valuable in academia/public research; both knowledge directly tied to subject areas (but more general type of knowledge rather than specialist knowledge in PhD topics) and the more general and transferable skills are regarded as valuable in technical positions in manufacturing; and the general and transferable skills are regarded as more valuable in employment outside the conventional technical occupations. In absolute terms, general analytical skills and problem solving capability acquired from doctoral education are perceived as valuable in all three career types. 相似文献

While multitasking is not a new concept, it has received increasing attention in recent years with the development of new media and technologies. Recent trends appear to suggest that multitasking is on the rise among the younger generation. The purpose of the study is to determine if students obtain more or less information in multitasking conditions. We examined the relationships of multitasking to attention, cognitive load and media with 130 college student participants. In this study, participants were given a timed (16 minutes) reading comprehension test in three conditions: Silence (only reading), Background multitasking (reading with a non-tested video shown simultaneously), and Test multitasking (reading with a tested video shown simultaneously) conditions. Our findings indicated that: (1) participants in the Background condition performed as well as those in the Silence condition, and (2) when participants were tested on their video comprehension, the group in the Test condition performed significantly better than the group in the Background condition. The results of this study suggest that cognitive load plays an important role in determining how much information is retained when students perform more than one task at a time. 相似文献

ObjectiveThe present study extends field research on interviews with young children suspected of having been abused by examining multiple assessment interviews designed to be inquisitory and exploratory, rather than formal evidential or forensic interviews.MethodsSixty-six interviews with 24 children between the ages of 3 and 6 years who were undergoing an assessment for suspected child abuse were examined. Each child was interviewed 2, 3, or 4 times. The interviewer's questions were categorized in terms of openness (open, closed or choice), in terms of the degree of interviewer input (free recall, direct, leading, suggestive), and for topic (whether the question was abuse-specific or nonabuse-related). Children's on-task responses were coded for amount of information (number of clauses) reported in relation to each question type and topic, and off-task responses were categorized as either ignoring the question or a diverted response.ResultsChildren provided a response to most questions, independent of question type or topic and typically responded with one or two simple clauses. Some children disclosed abuse in response to open-ended questions; generally, however, failure to respond to a question was more likely for abuse-specific than for nonabuse-related questions.ConclusionThe findings are discussed in terms of the growing literature on interviewing children about suspected abuse, particularly in interviews conducted over multiple sessions.Practice implicationsAssessment of suspected child abuse may involve more than a single investigative interview. Research examining children's responses to questioning over multiple interviews (or single interviews conducted over multiple sessions) is necessary for the development of best practise guidelines for the assessment of abuse. 相似文献
