Abstract

Fitness levels of American youth have shown a marked decline in the last decade, according to recent studies. To determine whether such a tendency persists for entering college students, the authors evaluated 115 male and 143 female students for performance on the following fitness-related variables: (1) maximal oxygen consumption (estimated from Astrand cycling protocol), (2) body composition (skin-fold techniques), (3) muscle endurance (sit-up protocol), (4) muscle strength (bench-press protocol), and (5) joint flexibility (upper and lower body protocols).

Although neither men nor women exhibited high levels of cardiorespiratory fitness, the women in the study showed higher relative levels than their male counterparts. Both groups showed excellent levels of muscle strength (compared with normative standards), but they achieved only an average standard for muscle endurance. Findings of relatively low levels of cardiovascular fitness compared with levels of muscle strength, particularly in men, seem to be a reflection of an inappropriate concentration of physical activity.  相似文献

We propose a novel literature review method in order to systematically trace and reveal the dominant narratives of a body of literature: the model‐narrative review method. We apply this method to an ever‐growing literature on ecosystems in business studies, as it resembles a rich knowledge base with somewhat competing, overarching stories, replete with emplotted characters, systematic puzzles and embellished scientific drama. To interpret these unfolding storylines, we both separately engage with and connect seminal work on business, entrepreneurial and innovation ecosystems. Through thematic reading we map the key themes and scientific puzzles in each ecosystem type. Through enstoried reading we identify how authors construct the plot, narrative setting, emplotted characters, narrative voices and moral lessons around ecosystems. Through rhetorical reading we explicate the rhetorical devices and strategies that claim the relevance of their work. Our findings expose a number of hidden meanings and underlying assumptions, adding transparency to ecosystem rhetorics and enhancing conceptual clarity. Altogether, this method offers a systematic construction of model‐narratives to synthesize and critically reflect upon similarities and differences between related concepts and opens up space for alternative research questions.  相似文献

The spread of COVID‐19 acutely challenges and affects not just economic markets, demographic statistics and healthcare systems, but indeed also the politics of organizing and becoming in a new everyday life of academia emerging in our homes. Through a collage of stories, snapshots, vignettes, photos and other reflections of everyday life, this collective contribution is catching a glimpse of corona‐life and its micro‐politics of multiple, often contradicting claims on practices as many of us live, work and care at home. It embodies concerns, dreams, anger, hope, numbness, passion and much more emerging amongst academics from across the world in response to the crisis. As such, this piece manifests a shared need to — together, apart — enact and explore constitutive relations of resistance, care and solidarity in these dis/organizing times of contested spaces, identities and agencies as we are living–working–caring at home during lockdowns.  相似文献

This article examines how planning on dairy farms is affected by farmers' motivation. It argues that farmers' choice of expansion strategies can be specified in terms of risk decision making and understood as either prevention‐focused or promotion‐focused motivation. This relationship was empirically examined using mediated regression analyses where promotion/prevention focus was the independent variable and its effect on total milk production via planned expansion strategies was examined. The results indicate that promotion focus among farmers has an indirect effect on farm expansion via planning strategies that incur greater risk to the farm enterprise. Regulatory focus on the part of farmers has an influence on farmers' planning and risk management activities and must be accounted for in the design and implementation of policy and risk management tools in agriculture.  相似文献

This study aimed to evaluate the comparative effectiveness of individual therapy and combined individual and group therapy in the treatment of the psychological sequelae of child sexual abuse. The Child Behaviour Checklist (CBCL), the Youth Self Report form (YSR), the Children's Depression Inventory (CDI) and the Trauma Symptom Checklist for Children (TSCC) were administered before treatment and 6 months later to a group of 20 young people who participated in individual therapy (IT) programmes and to a group of 18 young people who participated in programmes that involved combined individual and group therapy (IGT). For both types of programmes, statistically significant improvement occurred on the following scales: the total problems, internalizing problems, externalizing problems, withdrawn, somatic complaints, anxious/depressed, social problems, attention problems and aggressive behaviour problems CBCL scales; the total depression, interpersonal problems and anhedonia CDI scales; and the depression and anger TSCC scales. The only scale for which one therapy programme led to greater improvement than another was the CDI ineffectiveness scale. The IGT programme led to a reduction in the mean CDI ineffectiveness score, whereas a slight increase in the mean ineffectiveness score occurred in the IT group. There were no significant differences in the rates of clinically significant improvement associated with the two treatments and no major differences between cases who improved and those that did not improve over the course of therapy. From this study, it may be concluded that after 6 months, individual therapy and combined individual and group therapy were equally effective in the treatment of the psychological sequelae of child sexual abuse.

Children aged 8–12 years took 723 photographs representing well‐being. Another group of children categorised the photographs, identified what was missing and discussed their inter‐relationships. The largest categories were ‘people I love the most (friends)’ (23.2%), ‘activities’ (18%), ‘food and drink’ (17.2%) and ‘animals/pets’ (12.8%). Children reported that the categories were all related and could be subsumed into the general category ‘the way I live’, reflecting their holistic integrationist perspective on well‐being which in turn mirrors the whole child perspective of the Irish National Children's Strategy. The usefulness and limitations of this approach to working with children are discussed. Copyright © 2005 National Children's Bureau.  相似文献

This article is a messy account not of the COVID‐19 pandemic but one written during the pandemic. Although written over several successive evenings it is not a linear narrative that builds on a chain of passing moments teleologically to an end. It is not a diary, just a collection of scattered thoughts about living during COVID‐19, the (lack of) care that many elderly people receive and how we, or perhaps only I, struggle to cope in these exceptional times. This is not a typical autoethnography, it is not reflexive writing and there is no conclusion albeit that the article ends.  相似文献

Abstract

Smoking cessation behaviors of college students using a university health service were examined. Forty successful and 32 unsuccessful quitters were interviewed through an open-ended questionnaire. Elements important in successful, self-initiated cessation were sought. Results demonstrated many similarities between the groups. Differences seemed related to techniques used to remain abstinent from cigarette smoking, expectations of ease or difficulties in quitting, and the influence of a boyfriend/girlfriend. These differences should be studied in a larger sample. Questions raised for further study include: examining the influence of the health service and physician; identifying differences in attitudes toward cessation between quitters and recidivists; and evaluating what use smokers make of the knowledge gained through previous cessation attempts.

“Postprandial Glucose and Insulin Responses to Meals Containing Different Carbohydrates in Normal and Diabetic Subjects,” John P. Bantle, et al. To examine whether the form of dietary carbohydrate influences glucose and insulin responses, we studied the glucose and insulin responses to five meals–-each containing a different form of carbohydrate but all with nearly identical amounts of total carbohydrate, protein, and fat–-in 10 healthy subjects, 12 patients with Type I diabetes, and 10 patients with Type II diabetes. The test carbohydrates were glucose, fructose, sucrose, potato starch, and wheat starch. In all three groups, the meal containing sucrose as the test carbohydrate did not produce significantly greater peak increments in the plasma concentration of glucose or greater increments in the area under the plasma glucose-response curves than did meals containing potato, wheat, or glucose as test carbohydrates. Urinary excretion of glucose in patients with diabetes was not significantly greater after the sucrose meal. The meal containing fructose as the test carbohydrate produced the smallest increments in plasma glucose levels, but the differences were not always statistically significant. In healthy subjects and patients with Type II diabetes, peak serum concentrations of insulin were not significantly different in response to the five test carbohydrates.

Our data do not support the view that dietary sucrose, when consumed as part of a meal, aggravates postprandial hyperglycemia. (New England Journal of Medicine 1983;309:7–12.)  相似文献

Abstract

A new compulsory-with-waiver health insurance plan at the State University of New York at Buffalo (SUN-YAB) was designed in 1976 after assessing available literature on students' insurance, morbidity, health care costs, attitudes, data from past SUNYAB insurance plans and health service statistics. Previous findings that the morbidity of this population is low is corroborated by the data available on the students considered within this project. Illnesses common to this age group are predominantly acute, and require a low rate of hospitalization. The new insurance program cost an unmarried single student $67.00 and was a success by several criteria. Approximately 5,000 more students were enrolled in the complusory plan than in the previous voluntary one. Among students interviewed, both those who enrolled and those who did not, felt that the idea of compulsory health insurance for students was a good idea. Virtually all full-time students in the university were covered by some health insurance.  相似文献
