ABSTRACTInterval exercise training is increasingly recommended to improve health and fitness; however, it is not known if cardiovascular risk is different from continuous exercise protocols. This systematic review with meta-analyses assessed the effect of a single bout of interval exercise on cardiovascular responses that indicate risk of cardiac fibrillation and infarction compared to continuous exercise. Electronic databases Medline, CINAHL, Embase, Scopus and Cochrane were searched. Key inclusion criteria were: (1) intervals of the same intensity and duration followed by a recovery period and (2) reporting at least one of blood pressure, heart rate variability, arterial stiffness or function. Cochrane Risk of Bias tool and GRADE approach were used. Meta-analyses found that systolic blood pressure responses to interval exercise did not differ from responses to continuous exercise immediately (MD 8 mmHg [95% CI ?32, 47], p = 0.71) or at 60 min following exercise (MD 0 mmHg [95% CI ?2, 1], p = 0.79). However, reductions in diastolic blood pressure and flow-mediated dilation with interval exercise were observed 10–15 min post-exercise. The available evidence indicates that interval exercise does not convey higher cardiovascular risk than continuous exercise. Further investigation is required to establish the safety of interval exercise for clinical populations. 相似文献

This paper explores the experiences of a group of academic developers who support educational development work as Faculty Liaisons at a large, research-intensive university. These academic developers inhabit complex ‘third spaces’, providing support through an embedded partnership relationship that requires lateral movement across functional and organizational boundaries to create new professional spaces, knowledge, and relationships. The authors utilize narrative inquiry and auto-ethnographic approaches to present an interpretive qualitative analysis of their experiences supporting Faculty and University projects across complex and evolving organizational boundaries. From this analysis, they highlight key roles and responsibilities associated with their blended context and identify challenges that academic developers who occupy third spaces within academic organizations face as they negotiate competing interests, identities, and requirements associated with the diverse range of their projects and the blended experience of working in scholarly and administrative, central- and Faculty-based roles. The lessons they have learned from these experiences will be of particular interest to academic developers who are experiencing the flux of change within higher education settings that are impacting teaching and learning practices both for faculty in the classroom and for those across the institution who support them. 相似文献

This study examined associations among early adversity, diurnal cortisol, child sex, and caregiver sensitivity at age 6 months in relation to wheezing in children (47% male) followed to 30 months. Analyses included 676 mother-child dyads, 393 of whom completed an observational caregiver sensitivity measure. Participants were primarily ethnic minorities (42.7% Black, 25.4% Hispanic); 22.1% of children had ≥ 1 wheezing episode. Higher adversity was associated with increased wheeze frequency and blunted diurnal cortisol slope. The indirect effect of adversity on wheezing through cortisol slope was significant for females, but not males. Higher caregiver sensitivity was protective against wheezing for males, but not females, with high cortisol. Findings suggest complex associations among adversity, cortisol, child sex, and caregiver sensitivity in predicting wheezing. 相似文献

The theoretical basis, the development and the use of an inventory designed to measure styles of learning and motivation are described. On the basis of previous research, items within the inventory were located on 20 sub-scales. The ten motivation sub-scales were derived from a theory of school motivation which was based on extensive interview and inventory work carried out in Hungary with children, their parents and teachers. The ten scales describing styles of learning were derived from concepts describing learning approaches and styles which emerged from interviews and experimental research with students in British and Swedish higher education. Versions were prepared in both English and Hungarian and given to samples of 614 British and 579 Hungarian pupils aged between 13 and 17 years. A remarkably similar factor structure was obtained in each sample. An analysis of mean scores indicated distinctive differences both between boys and girls, and between British and Hungarian pupils. Cluster analysis was used to investigate the possible existence of styles which combined both approaches to learning and aspects of school motivation. The potentiality of the inventory for use in conjunction with study skills courses is discussed. 相似文献

Conclusion In order to make PIHnet forum more usable and useful, we recently redesigned the forum tool based on findings from a survey,
interviews and observations of user posting patterns. We also developed a journal tool to assist teachers with their personal
reflection.
Interviews with four users showed that the new forum was easy to use and effectively helped them communicate with other members.
We are still developing the journal tool, so user experiences with the new journal tool have not been investigated yet. We
will continue to improve the tools based on critical feedback from actual users. 相似文献

We collected data at a large, very selective public university on what math and science instructors felt was the biggest barrier to their students’ learning. We also determined the extent of each instructor’s use of research-based effective teaching methods. Instructors using fewer effective methods were more likely to say the greatest barrier to student learning was the internal deficiencies of the students (the “fundamental attribution error”). They listed deficiencies such as poor preparation and work ethic. In total, 37 % of the instructor attributions were to student deficiencies, but this fraction varied dramatically between departments. 相似文献

The Door-in-the-Face (DITF) sequential message strategy was investigated in a three-study analysis of existing experimental findings. The current study predicted there would be a positive relationship between concession size and compliance rates in DITF studies. Study 1 included 25 comparisons where size of concession was quantifiable as measured by percentage reduction from initial to target request in the DITF condition. Study 2 data relied on a panel of undergraduate students to provide an index of concession size in 12 additional observations. A third study validated the panel procedure of rating concession size and also provided 9 additional independent observations from the pool of published studies on DITF. Results from each study indicated a positive relationship between concession size and effect size (r = 0.35, 0.55, 0.68, respectively). Study findings provide support for reciprocal concessions explanation for DITF effects. 相似文献

The current study investigated the content of future perceptions among 47 U.S. women and 48 Israeli women. Thematic analysis was used to explore participants’ qualitative responses. Women’s responses covered a wide range of topics, and were categorized into ten key themes: (a) work, (b) family/relationships, (c) property, (d) residence, (e) education, (f) general quality of life, (g) leisure, (h) pro-social activities, (i) multiple role management, and (j) religion. Results demonstrated the role of nationality in the process of exploration and future perceptions. Implications for research and practice are discussed. 相似文献
