河南省城镇居民体育消费结构分析

采用问卷调查法，对河南省城镇居民体育消费行为进行调查。结果显示，河南省居民体育消费能力低于全国水平，实物性体育消费占主导地位，观赏性体育消费相对滞后，参与性体育消费有快速增长势头。提出发展河南省城镇居民体育消费的对策。     

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.     

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.     

A prospective examination of the impact of high levels of exercise training on sedentary behaviour

The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (?3, ?2, and ?1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Results: Twenty-three individuals (mean?±?S_x: 34.4?±?2.1y, 23.0?±?1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2?±?9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute^?1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.     

Use of the meeting street school screening test and the myklebust pupil rating scale with first-grade black urban children

This study hypothesized that: (a) the MSSST would identify the same proportion (15%) of high-risk children in a group (N = 580) of first-grade urban black children as estimated for the general population; (b) the Myklebust would discriminate between high-risk (N = 22) and low-risk (N = 21) children within the minority group using the MSSST as the criterion variable; and (c) Myklebust ratings for the high-risk and low-risk young minority children would approximate ratings reported elsewhere for older white suburban samples of high-risk and low-risk children. All three hypotheses were confirmed. The MSSST may be appropriate for minority group children. The small number of teachers (N = 6) participating in the Myklebust ratings makes generalization about it hazardous without further replication.     

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.
