AbstractChildren’s connection to nature (CTN) is declining with each generation, a concerning trend given that CTN is positively linked to wellbeing and environmentalism. A primary cause of this decline is that twenty-first-century youth engage with screens for several hours each day, which to a large extent replaces nature-based play. Researchers have proposed that this change represents a transition in human orientation, particularly in Westernized societies, from nature (biophilia) to digital media (videophilia). Interventions promoting nature-based play must acknowledge digital-media use as a competing leisure pursuit, but the literature presents little guidance for designing programs that will attract young people who are more oriented toward digital media than nature. Drawing on a wide breadth of research, we address this gap through (1) exploring the implications of videophilia for nature-based programming and (2) summarizing recommendations from a narrative literature review for designing interventions that appeal to digital-media-oriented youth. 相似文献

This paper unearths how primary school children experience and can complement the Australian HPE curriculum within three unique school ground equipment scenarios that include an ‘empty’, ‘loose parts’ and a ‘traditional’ school ground context. Using direct observation, 490 scans were undertaken of the school grounds over five days. Field note observations recorded children's HPE learning experiences according to the curriculum, and predominant physical activity types and intensities were recorded. Implementing a variety of school ground equipment provisions was revealed to be important compared to the ‘empty’ school ground context for primary school children to meet HPE curriculum objectives. 相似文献

In 2010, South Africa became the first country on the African continent to host the FIFA World Cup. Crucially the hosting of such a prestigious tournament was seen as a chance to prove that this developing nation could host an event of this magnitude as efficiently as the developed economies who had hosted the previous editions of the event, such as Germany in 2006 and Korea and Japan in 2002. Significantly though, this flagship event was also promoted by FIFA as ‘Africa's Tournament' with South Africa encouraged to share the identity and success of 2010 with the entire African continent. Based on the findings from in-depth interviews conducted with event and destination stakeholders from national and regional South African Government departments, this article explores the 2010 tournament as a branding opportunity that was used to promote both the continent of Africa as well as the South African nation. Expanding upon previous studies in this area the challenges and successes of hosting the 2010 World Cup are examined as is the role of mega-events such as the 2010 FIFA World Cup in generating a nation and continent-wide branding legacy. Stakeholders specialising in sport event management, tourism, operations and communications reflect on the branding and exposure for both Africa and South Africa achieved as a result of the event and the degree to which this was coordinated and co-created between various stakeholders. Insights are also given as to the degree to which the branding gains achieved during the event have been leveraged post-2010. As such, this article offers an original socio-historic perspective on existing studies examining the impact of the 2010 tournament. 相似文献

This article examines issues of gender justice within men’s netball and mixed-gender indoor netball in New Zealand, primarily from philosophical and social policy-based perspectives. While netball has historically reflected and reinforced appropriate ideas of female physicality, in the early 1980s, the new and more radical New Zealand Men’s Netball Association (NZMNA) welcomed openly transgender female players. Although the association subsequently took a heteronormative turn, independent for-profit mixed-gender indoor netball have also provided somewhat transgender-inclusive spaces. After discussing feminist debates about mixed-gender sport including netball specifically, this article argues that there are good reasons to support mixed-gender indoor netball. It also argues, however, that this should be done while also recognising both NNZ’s defensive ‘voluntary segregation’ of women’s netball and the unfortunate decline of the early (more radical) NZMNA. The article also discusses some important criticisms of such a policy. 相似文献

ABSTRACTHigh-intensity-interval-training (HIIT) has been suggested to have beneficial effects in multiple populations across individual systematic reviews, although there is a lack of clarity in the totality of the evidence whether HIIT is effective and safe across different populations and outcomes. The aim of this meta-review was to establish the benefits, safety and adherence of HIIT interventions across all populations from systematic reviews and meta-analyses. Major databases were searched for systematic reviews (with/without meta-analyses) of randomised & non-randomised trials that compared HIIT to a control. Thirty-three systematic reviews (including 25 meta-analyses) were retrieved encompassing healthy subjects and people with physical health complications. Evidence suggested HIIT improved cardiorespiratory fitness, anthropometric measures, blood glucose and glycaemic control, arterial compliance and vascular function, cardiac function, heart rate, some inflammatory markers, exercise capacity and muscle mass, versus non-active controls. Compared to active controls, HIIT improved cardiorespiratory fitness, some inflammatory markers and muscle structure. Improvements in anxiety and depression were seen compared to pre-training. Additionally, no acute injuries were reported, and mean adherence rates surpassed 80% in most systematic reviews. Thus, HIIT is associated with multiple benefits. Further large-scale high-quality studies are needed to reaffirm and expand these findings.Abbreviations: ACSM: American College of Sports Medicine; BMI: Body Mass Index; BNP: Brain Natriuretic Peptide; BP: Blood Pressure; CAD: Coronary Artery Disease; CHD: Coronary Heart Disease; COPD: Chronic Obstructive Pulmonary Disease; CRP: c- reactive Protein; CVD: Cardiovascular Disease; DBP: Diastolic Blood Pressure; ES: Effect Size; FAS: Reduced Fatty Acid Synthase; FATP-1: Reduced Fatty Acid Transport Protein 1; FMD: Flow Mediated Dilation; Hs-CRP: High-sensitivity c- reactive Protein; HDL: High Density Lipoprotein; HIIT: High-Intensity Interval Training; HOMA: Homoeostatic Model Assessment; HR: Heart Rate; HTx: Heart Transplant Recipients; IL-6: Interleukin-6; LDL: Low Density Lipoprotein; LV: Left Ventricular; LVEF: Left Ventricular Ejection Fraction; MD: Mean Difference; MetS: Metabolic Syndrome; MPO: Myeloperoxidase; MICT: Moderate-Intensity Continuous Training; NO: Nitric Oxide; NRCT: Non-Randomised Controlled Trial; PA: Physical Activity; PAI-1: Plasminogen-activator-inhibitor-1; QoL: Quality of Life; RCT: Randomised Controlled Trial; RoB: Risk of Bias; RPP: Rate Pressure Product; RT: Resistance Training; SBP: Systolic Blood Pressure; SD: Standardised Difference; SMD: Standardised Mean Difference; TAU: Treatment-As-Usual; T2DM: Type 2 Diabetes Mellitus; TC: Total Cholesterol; TG: Triglycerides; TNF-alfa: Tumour Necrosis Factor alpha; UMD: Unstandardised Mean Difference; WC: Waist Circumference; WHR: Waist-to-Hip Ratio; WMD: Weighted Mean DifferenceKey points:
HIIT may improve cardiorespiratory fitness, cardiovascular function, anthropometric variables, exercise capacity, muscular structure and function, and anxiety and depression severity in healthy individuals and those with physical health disorders.
Additionally, HIIT appears to be safe and does not seem to be associated with acute injuries or serious cardiovascular events.

While dissection remains the method of choice for teaching human anatomy, ethical requirements for obtaining cadavers has made the process of acquiring human bodies more strenuous for institutions. In Africa and at the School of Anatomical Sciences in South Africa, dependence on unclaimed bodies has been prevalent. The aim of the present study was to determine whether more rigorous application of ethical consent has altered the provenance of the cadavers in the School of Anatomical Sciences, University of the Witwatersrand. The numbers of bequeathed/donated/unclaimed cadavers received over the period 2013–2017, as well as their sex and population affinity were analyzed. The majority (96.8%) of the cadavers dissected over the period were from bequests/donations. Marginally more females than males were available. In addition, the population affinity of the cadavers had changed from a majority of South African African (unclaimed) bodies to a majority of South African White (bequest/donated) bodies. The study shows that even with ethical constraints it is possible to transition from the use of mainly unclaimed bodies to the acquisition of bequeathed/donor bodies. However, there may be challenges in relation to anatomical collections in the School as few of the bequest/donated cadavers remain in the School to be added to the collections. These changes also affect the demographics of the Schools' collections. 相似文献

Historically, legislature has been utilized to facilitate appropriate use of cadavers in the anatomical sciences. However, cadaver acquisition and use have also been guided by ethically appropriate and morally acceptable principles. Various global and regional frameworks of “ethical practice” guide body donation, including the use of unclaimed bodies by institutions. These frameworks are responsive to, and reciprocal with the various ethical, moral and legal factors that influence the development of body donation programs. This reciprocity supports the notion that anatomists and anatomical societies have a responsibility to advocate for legal reform when required. In this study, two body bequest programs from geopolitically and socially disparate countries are used as cases to contrast existing legal and governance frameworks for body donation and to examine whether anatomists can direct the acquisition of ethically donated cadavers. The study includes an Australian donor program that has exclusively accepted bequests since its inception, and a South African program that has recently transitioned to a bequest system. Elements such as consent by next-of-kin and Inspector of Anatomy, use of unclaimed bodies and ethics committee approval amongst others, are compared. It is acknowledged that legal frameworks for cadaver acquisition generally deliver broad guidance on acceptable utilization of bodies for the anatomical sciences. However, professional discretion is of importance in adapting to societal needs and values. Thus, while anatomists have been able to progress toward more ethical practice than that which is required by the law, they must continue to do so as societal values evolve. 相似文献

Abstract It is now almost two decades since concerns were originally expressed regarding the participation of Asian heritage schoolchildren in physical education and sport. Since then, an increasing flow of research literature and, in many instances, successful school initiatives to implement positive multicultural/antiracist policies, have been undertaken to provide equality of opportunity for these pupils. However, problems of access and achievement in physical activity still affect this group and serious health concerns continue to occur, perhaps as a result of such low levels of participation. There remains little take‐up of sport as a career among Asian heritage children. Against the backdrop of these various concerns, this paper contributes to knowledge of issues surrounding the participation of Asian heritage boys in physical education and sport. Through use of interviews and observation, the research focuses on the experiences of primary and secondary age boys within four inner‐urban schools in the North West of England. Findings suggest, primarily, that the role of Asian heritage parents within the sport socialisation experiences of their children was highly influential. Multicultural/antiracist policies were working well within these schools and racism was not stated as the main reason for non‐participation; the low status afforded to physical education and sport, within the home and community, was found to be a more influential factor. Where schools had become proactive in addressing this issue, improved participation had resulted. Findings suggest that education should focus more on Asian heritage attitudes in addition to maintaining and enhancing the antiracism process. 相似文献
