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.

基于Longstaff-Schwartz模型的亚式信用利差看跌期权定价

在经典的Black-Scholes期权定价模型中无风险利率是固定不变的常数,实际金融市场上的利率是变化的。假设信用利差和无风险利率均服从Vasicek模型,在此假设下给出亚式信用利差看跌期权的定价公式并利用随机过程的相关理论对定价公式进行证明。这种研究方法还可以用在具有浮动执行价的信用利差看跌期权。     

Revisiting the occupational aspirations and destinations of Anglo-Australian and Chinese-Australian high school students

Evidence from Australia lends support to the “Asian high achieving syndrome” in Chinese-Australian students and “self-deprivation syndrome” in Anglo-Australian students. Applying ethnographic case studies approach for doctoral thesis the author collected data on a longitudinal basis from homes and school of these students. All of these students attended the same school located in a predominantly middle class suburb of Perth Metropolitan area in Western Australia. Chinese-Australian families had settled in Perth from Malaysia, Singapore and Hong Kong, whereas Anglo-Australian families had been residing in Perth for three generations. Impetus to revisit these students (now young adults with their own families) 10 years later came from an urge to test the validity of the prediction the author had made in the concluding chapter of his doctoral thesis. The author had claimed that “if Anglo-Australian parents keep on dwelling in the era of 1950s and 1960s and do not change their laid-back attitude about education, their children could eventually be under-privileged in their own country”. Ten years later, the author undertook a follow-up study on these young adults from six of the eight original families in order to find out their occupational destinations and future aspirations. Data for the follow-up study were collected from these young adults and their parents. These research cases were interviewed twice, each time approximately for two hours and their parents were interviewed once for two to three hours. The purpose of this paper is to report the findings of the follow-up study which reveals a remarkable relationship between the attitude towards schooling and academic performance with their subsequent occupational destination.     

第27届男篮亚锦赛中伊实力对比分析

采用文献资料、录像观察、数理统计等方法,对参加第27届男篮亚锦赛的中伊男篮攻防数据进行定量、定性分析。结果表明:在场均攻防数据对比中,除了三分球和失误两指标接近外,中国队在各项指标上都要明显低于伊朗队;球队风格方面:伊朗队高强度防守、快节奏攻防转换是整体实力高于中国队的制胜因素;在各位置球员效率方面:中国队在内线方面较伊朗队仍有优势,但其他两位置能力明显不足,使球队整体"木桶效应"突显。
