Poverty,ethnicity, and risk of obesity among low birth weight infants

The independent and joint effects of family and neighborhood poverty and ethnicity upon weight trajectories from age two to six-and-a-half were examined using data from the Infant Health and Development Program (N = 985), an early intervention program for low birth weight children and families. At age two, family poverty was associated with higher body mass index (BMI), whereas neighborhood poverty and ethnicity were not. Over time, the BMI of toddlers from poor and near poor neighborhoods increased nonlinearly, while those from nonpoor neighborhoods remained stable. BMIs of Hispanic-American toddlers increased steadily over time, unlike African-American and Anglo-American toddlers. Although initially similar, over time African-American toddlers' BMIs increased more rapidly than Anglo-American toddlers. Family and neighborhood poverty and ethnicity were associated with BMI. More work is needed on how poverty and ethnicity contribute to differences in early weight gain in conjunction with sociocultural and environmental factors in the home and community.

Male physical attractiveness in Britain and Malaysia: A cross-cultural study

Three purported cues to perceived male physical attractiveness are the waist-to-chest ratio (WCR), body mass index (BMI) and the waist-to-hip ratio (WHR). This study examined the relative contribution of each cue in several socio-economically distinct populations. Ninety-five female participants from Britain and Malaysia were asked to rate a set of images of real men with known WCR, BMI and WHR. The results showed clear differences along a gradient of socio-economic development. In urban settings, WCR was the primary component of attractiveness ratings, with BMI playing a smaller role and WHR not reaching significance. In the rural setting, BMI was the primary predictor of attractiveness, with WCR playing a more minor role and WHR not reaching significance. In general, urban participants were more reliant on body shape and chose a relatively slim figure with an ‘inverted triangle’ shape; rural participants were more reliant on body weight and chose a heavier figure with a less triangular shape. These findings are discussed in terms of evolutionary psychological explanations of mate selection and sociological theories that emphasise the effect of resource scarcity on preferences for body shapes and sizes.     

汉字笔迹与个性测评研究

本文采用汉字笔迹测量法和80－8神经类型量表法对大、中、小学生共计2153人进行了团体测验,各项测量指标所得到的数据,经统计检验,其主要结论如下：1．笔迹特征表现为年龄越小,以直笔、重笔、慢速、光边占的比例越大,13岁以后,笔迹特征出现明显分化,这表明,个性在13、14岁年龄阶段开始加速形成与发展．2．笔迹书写形式、书写速度、书写压力及稳定性等心理特征指标与其神经类型特征有密切的关系．3．根据笔迹书写形式、速度、压力及稳定性等基本特征指标的不同组合,划分为8种气质类型,并在实际应用中获得较为满意的效果．     

A note to Bollen's alternative fit measure

The problem of dependence of the nonnormed fit index on sample size in covariance structure analysis is discussed. Contrary to Bollen (1986) we show that the mean of the nonnormed fit index is independent of sample size for true and almost true models whereas Bollen's alternative index does depend on sample size.
