Abstract Individuals with impaired glucose tolerance (IGT) are at greater risk of developing diabetes than in normoglycaemia. The aim of this study was to examine the effects of 12-weeks exercise training in obese humans with IGT. Eleven participants (6 males and 5 females; 49±9 years; mean Body Mass Index (BMI) 32.4 kg · m?2), completed a 12-week brisk walking intervention (30 min per day, five days a week (d · wk?1), at 65% of age-predicted maximal heart rate (HRmax). Anthropometric measurements, dietary intake, pulse wave velocity (PWV, to determine arterial stiffness) and blood pressure (BP) were examined at baseline and post intervention. Fasting blood glucose, glycosylated haemoglobin, insulin, blood lipids, indices of oxidative stress and inflammation (lipid hydroperoxides; superoxide dismutase; multimeric adiponectin concentration and high-sensitivity C-reactive protein) were also determined. Post intervention, PWV (9.08±1.27 m · s?1 vs. 8.39±1.21 m · s?1), systolic BP (145.4±14.5 vs. 135.8±14.9 mmHg), triglycerides (1.52±0.53 mmol . L?1 vs. 1.31±0.54 mmol . L?1), lipid hydroperoxides (1.20±0.47 μM · L?1 vs. 0.79±0.32 μM · L?1) and anthropometric measures decreased significantly (P < 0.05). Moderate intensity exercise training improves upper limb vascular function in obese humans with IGT, possibly by improving triglyceride metabolism, which may subsequently reduce oxidative stress. These changes were independent of multimeric adiponectin modification and alterations in other blood biomarkers. 相似文献

Students with persistent disruptive behavior problems lose valuable time in academic lessons, are a distraction for classmates, and cause stress for teachers. Recent meta-analyses indicate that 87% to 92% of published studies on school-based interventions targeting student problem behaviors report results from demonstration projects (involving highly trained staff under ideal circumstances) rather than routine practice programs. This study investigates the routine use of a schoolwide classroom management program and its relationship to elementary students’ social and academic outcomes. Three years after training in the classroom management program, 56 second-, third-, and fourth-grade teachers in an urban school district were assessed for fidelity to the program. Program fidelity was determined via direct observation in the classroom and validated by teacher self-ratings of fidelity and administrator ratings of teacher fidelity. Dependent variables included student engagement during academic lessons, out-of-school suspension rates, and report card grades. Results indicated that high program fidelity was significantly related to greater academic engagement and fewer suspensions, but not higher report card grades. This study adds to the scant literature on implementation fidelity of routine programs with high-risk populations. 相似文献

The American aspiration for higher education as a road to a better life for everyone is threatened. As the economic and social gap between the upper third of the population and the bottom third widens, so access to better education, especially to higher education, becomes increasingly difficult to achieve. The traditional role of hope in the American Democratic Dream of a just and fair society is being eroded, as increasing numbers of Americans are marginalized, jailed, recruited into military service, and consigned to jobs with minimal salaries. But low‐paying jobs are not new in American history; what is new is that the hope for higher education and improvement in one's economic and social status is slipping away. The lower expectations result from federal cuts in support of education and for scholarships for higher education. This article reviews the conditions that are undermining the traditional visions of democratic schooling in America. 相似文献

The paper conducts a statistical analysis of the dynamics of the sale of new music (product differentiation innovation) in the record industry. In pursuing this goal the paper generates new data and analyses a previously unutilized data set. The paper finds that there is a strong correlation between new music innovation in the audio singles and albums market. This is found to be mainly concurrent in the same quarter and to have a reasonably short product life. The paper discovers that these features also characterise the dynamics of record company performance. The research indicates that record companies are willing to sell singles at a loss due to advertising rather than learning externalities. At the industry level, the paper finds that new music innovation does not effect market size significantly and mainly causes business stealing effects between record companies, with exceptional cases of multiplier effects. 相似文献

Olympic combat sports separate athletes into weight divisions, in an attempt to reduce size, strength, range and/or leverage disparities between competitors. Official weigh-ins are conducted anywhere from 3 and up to 24?h prior to competition ensuring athletes meet weight requirements (i.e. have ‘made weight’). Fighters commonly aim to compete in weight divisions lower than their day-to-day weight, achieved via chronic and acute manipulations of body mass (BM). Although these manipulations may impair health and absolute performance, their strategic use can improve competitive success. Key considerations are the acute manipulations around weigh-in, which differ in importance, magnitude and methods depending on the requirements of the individual combat sport and the weigh-in regulations. In particular, the time available for recovery following weigh-in/before competition will determine what degree of acute BM loss can be implemented and reversed. Increased exercise and restricted food and fluid intake are undertaken to decrease body water and gut contents reducing BM. When taken to the extreme, severe weight-making practices can be hazardous, and efforts have been made to reduce their prevalence. Indeed some have called for the abolition of these practices altogether. In lieu of adequate strategies to achieve this, and the pragmatic recognition of the likely continuation of these practices as long as regulations allow, this review summarises guidelines for athletes and coaches for manipulating BM and optimising post weigh-in recovery, to achieve better health and performance outcomes across the different Olympic combat sports. 相似文献

Equity and widening participation (EWP) initiatives in Australia are increasingly reimagined in policy as sites where participants are constructed as competitor-individuals, with education considered only in terms of employability, social mobility and nation-state market competition. In the context of EWP outreach, and with school students in particular, this can transpire into demands for narrow forms of ‘legitimate’ aspirations. Goffman defines obscenity as when (1) the very intimate is forced into the public sphere, while (2) the humanising dimensions or contexts are stripped away, with an example being pornography—where intimate encounters are reproduced as de-contextualised acts while being made public. This article argues that dominant approaches to practicing and evaluating EWP risk obscene consequences if they force community members to present static future-oriented valuations of intimate, fluid aspirations and experiences of education against a backdrop of increasingly individuated, competitive and standardised educational institutions. In this article, firstly we detail the context to establish a foundation for theorising consequences of particular socio-educational discursive practices. Secondly, we engage with notions of frame, keying and fabrication as a toolbox to reveal some of the unintended (obscene) dynamics risked via certain approaches to programmatic practice and evaluation. Thirdly, we review the diversity of approaches to evaluation (and their attendant debates), highlighting the importance of these debates and diversities, making a case against methodological imperialism. 相似文献

The ever‐increasing role of the forensic sciences in the criminal justice system requires criminal justice educators to integrate the study of forensic science into a traditional social science curriculum. Yet, most professors in criminal justice lack forensic science expertise sufficient to meet the educational demands of the field, as it is intertwined with natural science disciplines, especially biology and chemistry. Accordingly, this paper advocates the formation of an interdisciplinary forensic studies program, including a discussion of need, curricular components, and overcoming potential obstacles. 相似文献

Abstract A survey of community college personnel in Connecticut, New York, and New Jersey was conducted to determine (1) the extent and type of services in speech, hearing, or language screening, remediation, and improvement, (2) the extent and type of instruction in speech and language improvement, and (3) the extent and type of bilingual services in speech, hearing or language presently offered to students and community members within the community college setting. In addition, the existence of plans to offer these services in the future was ascertained. Responses indicated the existence of some services but a general unavailability of comprehensive screening, evaluation, and rehabilitation programs despite the widespread needs of the growing community college constituency. The results of the survey can assist community college personnel in needs assessment and planning within their own institutions by offering a context for consideration of the priority for providing language, speech, and hearing services within the community college setting. 相似文献
