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 study assessed the impact of coworker support on lactating mothers’ breastfeeding self-efficacy after maternity leave. A cross-sectional survey of 1000 working adults assessed effects of perception of fairness, coworkers’ support for breastfeeding colleagues, and ick response on willingness to help mothers needing breaks to pump breastmilk at work. The study also examined how coworker support affected mothers’ self-efficacy to continue breastfeeding. One out of four coworkers showed moderate to strong stigma, saw breaks to pump breastmilk as unfair, and showed less intention to help new mothers. These results suggest that while the majority of coworkers are generally supportive, lactating women are likely to encounter disapproving coworkers who may discourage them from continuing to breastfeed. The data showed that the majority of organizations included in this study have only passively fostered mother-friendly workplaces and could do more to encourage employees to be supportive of lactating colleagues. 相似文献

There are increasing calls for pre-service educators to be responsive and responsible for anti-homophobic education. This research builds on the ongoing efforts to integrate Positive Space training in our two-year Bachelor of Education programme. We found through a series of focus group and individual interviews that pre-service teachers were aware of Lesbian, Gay, Bisexual, Transgendered, and Queering/Questioning (LGBTQ) oppression, witnessed it in schools, employed a range of strategies, but also experienced challenges due to power dynamics in schools, and may not have recognised the power of their interruptions. Our findings suggest that Positive Space training is valuable and necessary and needs to continue to be explicitly embedded in core courses so that all pre-service teachers, regardless of their discipline, develop the skills and attitudes necessary to be advocates for LGBTQ individuals. 相似文献

This study examined differences in physicians’ perceptions of their disclosure patterns toward cancer patients based on their professional ideological orientation. Adapting Strauss et al.’s (1964) sociotherapeutic (SCT) and somatotherapeutic (SMT) ideologies, it was hypothesized that physicians who strongly identified with the SCT ideology would perceive themselves as more willing to disclose the diagnosis to cancer patients and that there would be differences in the way and types of information presented depending on physicians’ ideological orientation. The findings suggest that physicians perceive choosing particular disclosure patterns based, in part, on their professional ideological orientations. Those who identify with a strong SCT orientation perceive themselves as more willing to disclose the diagnosis and provide some additional information to cancer patients and their families. Implications of these findings and directions for future research are discussed. 相似文献

In curriculum policy, discourses of ‘policy partnerships’ and ‘communities of practice’ have become increasingly prevalent and were reflected in Western Australian curriculum policy processes from the mid‐1990s to the late 2000s – a period of significant, highly contested change. This paper presents the findings of an empirical study into the impact of curriculum reform on the changing dynamics within and between the government and non‐government education sectors, drawing on critical theory and post‐structuralist approaches to policy analysis within a broader framework of policy network theory. This approach is used to highlight power issues at all levels of the policy trajectory. This research found that despite policy discourses of collaborative and consultative processes to create a ‘shared’ curriculum, the government and non‐government education sectors remain largely distinct due to significant power differentials, as well as structural and cultural differences. The analysis reveals three closely connected emergent themes – limited collaboration, regulated consultation and enhanced state control of curriculum policy agendas. It is argued here that although discourses of ‘policy partnerships’ and ‘community of practice’ are increasingly evidenced in contemporary curriculum policy, they do not take sufficient account of embedded hierarchical power relationships. Further, such discourses can be used as legitimisation strategies to promulgate policy changes which enhance the steerage capacity of the state. Deeply entrenched power differentials operate simultaneously to distort policy partnerships and communities of practice, by both including and excluding particular sets of policy actors. 相似文献

In recent years, action on sustainability has been highly influential around the globe and many now recognize the importance of individual and social learning for inspiring action and achieving sustainability outcomes. Transformative learning theory has been criticized, however, for insufficient development of the link between learning and action. The purpose of this paper is to deepen our understanding of the learning–action cycle among adult learners in the sustainability context. We consider this through insights from two studies in Kenya and Canada, utilizing a qualitative approach. Both studies employed semi-structured interviews as their primary data collection instrument and used other tools such as focus groups and journal writing. Three broad nodes of social action—individual, interpersonal and collective—are identified and defined based on the data collected. Results show that while all three types of action were evident in the outcomes of participants, individual social action was the most common and collective social action was the least. Barriers to applying learning in action are also derived from the data, including situational, personal, interpersonal, sociocultural and environmental obstacles. Factors that assist in overcoming such barriers include community support networks and skills training. 相似文献

Children with spelling deficits demonstrate significant difficulty using inflectional morphology in their writing. This study investigated whether phonological deficits account for these pronounced difficulties or if they are more accurately explained by limitations in morphological or orthographic awareness. Twenty–six 11—13–year–old children with spelling deficits, 31 younger spelling–level–matched children, and 31 age–matched children were asked to spell a series of verbs with past tense and progressive markers in dictated sentences and in list form. Performance on spelling tasks was compared to performance on phonological, morphological, and orthographic awareness tasks. Results suggest that children with spelling deficits have significant difficulty including inflections as well as spelling inflections and base words. Difficulty was most pronounced in a sentence context. Ability to spell inflectional forms was related to variation in morphological awareness in children with spelling deficits and to variation in orthographic awareness in spelling–level–matched children. 相似文献
