ABSTRACT We compared cardiometabolic demand and post-exercise enjoyment between continuous walking (CW) and time- and intensity-matched interval walking (IW) in insufficiently active adults. Sixteen individuals (13 females and three males, age 25.3 ± 11.1 years) completed one CW and one IW session lasting 30 min in a randomised-counterbalanced design. For CW, participants walked at a mean intensity of 65–70% predicted maximum heart rate (HRmax). For IW, participants alternated between 3 min at 80% HRmax and 2 min at 50% HRmax. Expired gas was measured throughout each protocol. Participants rated post-exercise enjoyment following each protocol. Mean HR and V˙O2 showed small positive differences in IW vs. CW (2, 95%CL 0, 4 beat.min?1; d = 0.23, 95%CL 0.06, 0.41 and 1.4, 95%CL 1.2 ml.kg?1.min?1, d = 0.36, 95%CL 0.05, 0.65, respectively). There was a medium positive difference in overall kcal expenditure in IW vs. CW (25, 95%CL 7 kcal, d = 0.58, 95%CL 0.33, 0.82). Post-exercise enjoyment was moderately greater following IW vs. CW (9.1, 95%CL 1.4, 16.8 AU, d = 0.62, 95%CL 0.06, 0.90), with 75% of participants reporting IW as more enjoyable. Interval walking elicits meaningfully greater energy expenditure and is more enjoyable than CW in insufficiently active, healthy adults. 相似文献

ABSTRACTThis article suggests that situations in which multiple research teams are convened under similar conditions present an opportunity to discover factors that lead to productive collaboration. It argues that social network analysis of research team outputs becomes more valuable when paired with data about research participant perceptions; and that any variables used as indicators of collaboration need to be calibrated using datasets from multiple studies with cross-team comparisons. The article provides an example of the kind of methodology needed to achieve this, describing a study with data from four research teams based at an Australian university campus, reporting their research performance over four years under conditions in which many variables were controlled and with results augmented by a survey of participant perceptions. Findings from the study indicate that there were exceptions to hypothesized associations between participant perceptions of collaboration and specific social network analysis measures over co-authorship data. The article suggests that, given the methodological challenges of studying research teams in the field, multiple datasets combining findings such as those in the present study are a path towards the development of indicators of productive higher education research collaboration. 相似文献

Grit has been defined as passionate perseverance toward long-term challenging goals and it is associated with various positive outcomes for youth, including academic achievement. However, less is known about these associations for the two facets of grit (i.e., perseverance of effort, consistency of interest) and few studies have examined the link between grit and perceived social support. The present study examined the group-level demographic differences (i.e., gender, grade, socioeconomic status, and special education status) of grit in a high school sample (N = 1,077). In addition, direct associations between grit and perceived social support from multiple sources (i.e., teacher, classmate, parent) were examined, as well as a potential enhancing effect of social support as a moderator of the relation between grit and academic achievement. Results indicated positive associations among grit and its facets with social support from parents and classmates. Furthermore, the positive relation between grit and achievement was stronger for students reporting high social support from teachers, but not other sources (i.e., classmates, parents). Practical and theoretical implications for promoting student success are discussed. 相似文献

AbstractHow does a small community college library, without marketing experience or budget, advocate for its value to a campus community and its administrators? We did so by creating an engaging, bright, and easy-to-read “pocket-graphic.” In this column, we reflect on the process of shaping a multi-use product out of a mountain of data. Through research in design practices, field observations of popular information tools, and an uncomfortable step into braggadocio, we learned to articulate the successes of our library. Our “pocket-graphic” told our story, yes – but it also provoked surprise, questions (“you really have all that?”) and delight in the lesser known successes (“you really DO all that!”). In the process, we connected our students more deeply to helpful services and resources, faculty to supportive instruction, and positively changed the tone of conversation with all our stakeholders. By turning data points into selling points, we found insights and a focus that moved our own development forward, helping ourselves to define improved priorities for advancing our critical role in student success. 相似文献

Higher education as a personal, intellectual and moral cultivation is a longstanding ideal that is constantly challenged by the view that education is merely the development of specific skills for vocational and personal success. Much research argues that the latter understanding makes education a technical affair that creates an egocentric emphasis on the individual students’ ambitions and desires. This article joins in the defence of the former ideal by enquiring into the moral dimensions of education. This is done by turning to Iris Murdoch's idea of moral transformation, with a specific focus on the idea of unselfing. The main argument is that unselfing is a transformative process characterised by a growing attunement to the surrounding world, and the interconnectedness of goal and process is emphasised. Also, to gain a deeper understanding of what unselfing entails I turn to the idea of attention. It is understood as having a specific direction, outward from the egocentric, and as enabling unselfing. The article concludes by suggesting that unselfing can offer a challenge to (higher) education as it entails a moment of letting go of plans and narratives, and of surrendering to the influence of an existence that exceeds the individual. This moment is of relevance to education as it is crucial to the possibility of growing as a moral being as it cultivates a moral manner of relating to others. 相似文献

This article outlines evidence-based methods for cultural heritage institutions to look for news and mentions about their collections and services online. Google Alerts were created for repository names, websites, and finding aid websites for 66 institutions randomly selected from the Archive Grid database. Results were analyzed to determine Google Alerts' accuracy, what types of institutions would benefit most from using Google Alerts, what the content of the sources found by the alerts was, what types of publications returned the most results, and if Google Alerts could also identify image reuse. While Google Alerts' accuracy for returning usable results for analysis was not very high, the structure of alert e-mails makes discarding irrelevant results simple and quick. Mid- to large-sized museums and institutions staging frequent exhibits and events, as well as those with active collections, return the largest number of alerts. News publications and social media publish the most content related to cultural heritage institutions. Though the sample set was small, Google Alerts also was able to identify image reuse. 相似文献

ABSTRACT The systematic review and meta-analysis evaluated the effect of aerobic, resistance and combined exercise on RMR (kCal·day-1) and performed a methodological assessment of indirect calorimetry protocols within the included studies. Subgroup analyses included energy/diet restriction and body composition changes. Randomized control trials (RCTs), quasi – RCTs and cohort trials featuring a physical activity intervention of any form and duration excluding single exercise bouts were included. Participant exclusions included medical conditions impacting upon RMR, the elderly (≥65 years of age) or pregnant, lactating or post-menopausal women. The review was registered in the International Prospective Register of Systematic Reviews (CRD 42,017,058,503). 1669 articles were identified; 22 were included in the qualitative analysis and 18 were meta-analysed. Exercise interventions (aerobic and resistance exercise combined) did not increase resting metabolic rate (mean difference (MD): 74.6 kCal·day-1[95% CI: ?13.01, 161.33], P = 0.10). While there was no effect of aerobic exercise on RMR (MD: 81.65 kCal·day-1[95% CI: ?57.81, 221.10], P = 0.25), resistance exercise increased RMR compared to controls (MD: 96.17 kCal·day-1[95% CI: 45.17, 147.16], P = 0.0002). This systematic review effectively synthesises the effect of exercise interventions on RMR in comparison to controls; despite heterogenous methodologies and high risk of bias within included studies. 相似文献

The school setting represents the most common setting by which youth receive mental and behavioral health (MBH) services (Farmer et al., 2003, Psychiatr Serv, 54, 60–66). Nevertheless, many school psychologists are not providing MBH services despite the high prevalence of need. Additional research is needed to understand factors leading to these deficits, as well as potential solutions to ameliorate these concerns. The current study surveyed 341 school psychologists across seven states and found current ratios are one school psychologist for every 1,500–2,000 students. Study results suggest school psychologists are providing a half to full day of universal, prevention-oriented MBH services each week whereas more targeted, direct services (e.g., individual or small group counseling) are offered 1–4 hr each week. The school psychologist-to-student ratios also demonstrated a statistically significant and inverse association with the provision of targeted MBH services, with higher ratios resulting in fewer MBH services. Respondents provided potential solutions for how to expand the delivery of MBH services within schools, including increased awareness and support among school and district administrators, as well as access to training and professional development related to MBH services. 相似文献

Family Instability and Young Children's School Adjustment: Callousness and Negative Internal Representations as Mediators 下载免费PDF全文
This study examined the mediating roles of children's callousness and negative internal representations of family relationships in associations between family instability and children's adjustment to school in early childhood. Participants in this multimethod (i.e., survey, observations), multiinformant (i.e., parent, teacher, observer), longitudinal study included 243 preschool children (Mage = 4.60 years) and their families. Findings from the lagged, autoregressive tests of the mediational paths indicated that both children's callousness and negative internal representations of family relationships mediated longitudinal associations between family instability and children's school adjustment problems over a 2‐year period (i.e., the transition from preschool to first grade). Findings are discussed in relation to the attenuation hypothesis (E. J. Susman, 2006) and emotional security theory (EST; P. T. Davies, M. A. Winter, & D. Cicchetti, 2006). 相似文献

The study examined the ability of deaf and hearing students at the college and middle school levels to discern and apply knowledge of printed word morphology. There were 70 deaf and 58 hearing participants. A two-part paper-and-pencil test of morphological knowledge examined subjects' ability to (a) perceive segmentation of morphemes within printed words and (b) recognize meanings associated with various printed morphemes. The hearing college students performed best on every dependent measure of the two-part test. The deaf college students scored significantly lower than the hearing college students but similarly to the hearing middle school students. Deaf middle school students consistently scored the lowest on both parts of the test. While all students' performance declined as the difficulty of the morphemic content increased within both tasks, the decline was greatest among middle school deaf students. Although segmentation and semantic analysis skills necessary to morphographic decoding were apparent in the deaf students, their mastery levels fell significantly below those of the hearing subjects. 相似文献
