The effect of beetroot juice supplementation on repeat-sprint performance in hypoxia

This investigation assessed the effect of dietary nitrate (NO₃^?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO_2peak 53.1 ± 8.7 mL.kg^?1.min^?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYP_BR; 13 mmol NO₃^?) or NO₃^–depleted BR placebo (HYP_PLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO₂) was measured during the warm-up. There were no significant differences observed between HYP_BR and HYP_PLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYP_BR compared with HYP_PLA. There was a moderate effect for VO₂ to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO₃^? may not improve repeat-sprint performance in hypoxia but may reduce VO₂ during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.     

Rethinking participation in the Aarhus as European Capital of Culture 2017 project

This paper examines the relationship between cultural participation and regional development with reference to the European Capital of Culture in 2017. From the bidding stage, Aarhus 2017 claimed it put “participation” at the heart of its strategic plans, through consultation at roadshows and exhibitions. In addition, it aspired to use culture as a catalyst for development not only in the city of Aarhus but across the region of Central Denmark. This paper, therefore, examines how participation is defined and implemented to address regional development in the Aarhus 2017 process through textual analysis of documentation from Aarhus 2017 and delivery partners as well as over 20 interviews with managers and participants involved in a range of 2017 projects. The paper argues against the common prioritisation of urban and professional cultural institutions and makes the case for decentralised cultural provision that supports both amateurs and professionals through a regional networked structure.     

Effecting School Change: The Halton Approach

ABSTRACT

Two related but distinct questions are often asked by educators as they try to make their schools more effective. These are: “Which of the many activities that we do have greater benefits for students?” and, “How can we make our schools better than they are now?” The first question focuses specifically on the impact of schools on student outcomes and the characteristics of effective schools, whereas the second addresses the implementation of change and school improvement. This article addresses the research related to these two questions and describes the application of this research in a large school district in Ontario, Canada.

A Comprehensive Approach to Handling Sensitive Issues in Schools,with Special Reference to Loss and Grief

The School Watch initiative is centred in South Wales and involves police liaison officers, primary schools and their pupils. In each interested school, the scheme is explained and the pupils then decide if they want to take part. A pupils' committee is elected which is given support and guidance by the liaison officer. A key element of the scheme is the involvement of the pupils themselves and the way the pupils' committee plays a major part in the choice and running of activities. The scheme benefits pupils both in terms of their personal and social development and in their attitudes to the police. The paper ends with a number of examples of the type of work that schools have undertaken within this scheme.     

Subjected to review: engendering quality and power in higher education

Both feminism and quality assurance movements have attempted to deconstruct and reconstruct the academy. Both have called for more transparency in procedures, accountability from elite professional groups and the privileging of the student experience. Both are globalized systems calling for transformation. However, it is questionable as to whether these two forces for change can form strategic alliances, or whether indeed they are in oppositional relationship. As a dominant regime of power in the UK academy today, quality assurance both exposes the micropolitics of gendered power in organizations and creates its own structures and systems of power. Quality assurance is part of the modernization process of the public services. However, gender equity is not a performance indicator in UK quality audits. In this paper, I interrogate the gendered implications of quality assurance, with particular reference to the assessment of teaching and learning in the UK (the Quality Assurance Agency's Subject Review). Drawing on empirical data and conceptual critiques, I will argue that quality assurance, as a regime of power, is gendered in its conception and practice.     

Information asymmetry and information sharing

Although much digital divide research focuses on access to technology, another cause of the divide is the lack of information awareness that we call information asymmetry. Information asymmetry often stems from inadequate information sharing and can result in negative consequences for both the information poor and the information rich. Information asymmetry has been insufficiently studied as a possible cause of underdevelopment and inequality. In response, we develop a typology to classify information asymmetry into two categories, horizontal and vertical, and then identify those information sharing practices that cause the imbalance. To illustrate the negative consequences of information asymmetry and the potential benefits of information sharing, we discuss two examples from the experiences of modern American Indian tribes. First, Indian tribes face horizontal information asymmetry when they attempt to access the capital markets, and second, they face vertical information asymmetry in terms of law enforcement data sharing. This article also describes our ongoing examination of horizontal information sharing among tribes and vertical information sharing between tribes and others sovereigns in the American polity as possible solutions to the problems created by information asymmetry. These strategic responses are embodied in two information systems, the Tribal Financial Information Clearinghouse and an Intergovernmental Tracking System for sharing law enforcement data. We conclude with a discussion of how our typology can be more generally applied to other instances of information asymmetry.     

老龄澳大利亚籍华人的身体活动观

身体活动指“由骨骼肌产生的体能消耗运动”．是保持身体健康、增进社会交往的重要方式和途径。在澳大利亚，虽然有研究调查民族群体身体活动的各个层面，但总体而言．多数研究更侧重于民族群体的同质性，而忽视了其异质性。本研究探讨在新南威尔士州居住的澳籍香港老年华人对身体活动的概念理解及对身体活动的态度。研究使用开放性问卷进行个体深度访谈，受访者22人。研究发现，大多数受访者不清楚“身体活动”这一术语的含义，对他们来说，“身体活动”是一个模糊的、复杂的术语。该群体对身体活动的态度反映了他们在预防性卫生保健方面的文化和健康观念。显然，提升澳籍香港老年华人的身体活动水平．需要一种基于文化特殊性的健康促进策略以解决对身体活动的误解，同时也需要具体的身体活动态度与华人整体性保健观念相匹配。     

Physical activity patterns of ethnic children from low socio-economic environments within the UK

Many children fail to meet physical activity (PA) guidelines for health benefits. PA behaviours are complex and depend on numerous interrelated factors. The study aims to develop current understanding of how children from low Socio-economic environments within the UK use their surrounding built environments for PA by using advanced technology. The environment was assessed in 96 school children (7–9 years) using global positioning system (GPS) monitoring (Garmin Forerunner, 305). In a subsample of 46 children, the environment and PA were assessed using an integrated GPS and heart rate monitor. The percentage of time spent indoor, outdoor, in green and non-green environments along with time spent in moderate-to-vigorous PA (MVPA) in indoor and outdoor environments were assessed. A 2-by-2 repeated measures analysis of covariance, controlling for body mass index, BF%, assessed the environmental differences. The findings show that 42% of children from deprived wards of Coventry fail to meet PA guidelines, of which 43% was accumulated during school. Children engaged in more MVPA outdoor than indoor environments (P < 0.01) and a greater amount of time was spent in non-green environments (P < 0.01). Increased time outdoors was negatively associated with BF%. In conclusion, outdoor environments are important for health-enhancing PA and reducing fatness in deprived and ethnic children.
