Do physical activity beliefs differ by age and gender?

Age and gender are consistently related to physical activity (PA), yet theoretical explanation for these associations is scant. The present study compared the mean values and correlations of a population sample, divided by gender and age group, with respect to theory of planned behavior beliefs (behavioral, normative, and control) and PA. Participants were a sample (N=6,739) of adults (M age=49.65, SD=16.04) who completed measures of social and health demographics, theory of planned behavior beliefs, and self-reported PA. Mean analyses identified greater perceived control over PA for seniors than for young and middle-aged adults (N>.025). Belief-behavior correlations, however, were not different across age and gender in 24 of 26 tests (q<.19). Thus, PA beliefs are invariant across age and gender with the exception of mean levels of perceived control, which are lower among younger adults than older adults. Factors such as early parenthood and career demands were considered the likely reasons for differences. Overall, the evidence suggests that adapting theoretical models for specific age groups or based on gender may not be necessary.

Psychometric Properties of a Parental Questionnaire for Assessing Correlates of Toddlers’ Physical Activity and Sedentary Behavior

This study examined the psychometric properties of a questionnaire developed with the guidance of the socialization model of child behaviour to understand modifiable correlates of toddlers’ physical activity and sedentary behaviour. Findings are based on 118 parents (33.7 ± 4.9 years; 86% female) of toddlers (19.3 ± 2.7 months; 48% female) from Edmonton, Canada in The Parents’ Role in Establishing healthy Physical activity and Sedentary behaviour habits study (PREPS). The PREPS questionnaire encompassed 21 variables across the constructs of the socialization model of child behaviour. Of the nine variables assessed for internal consistency reliability, eight had good (α ≥ 0.70) reliability. Of the 15 continuous variables assessed for 1-week test–retest reliability, 10 had moderate (intra-class correlation = 0.50–0.74) and 5 had good (intra-class correlation ≥ 0.75) reliability. Of the six categorical variables assessed for 1-week test–retest reliability, two had fair (К = 0.21–0.40), one had moderate (К = 0.41–0.60), one had substantial (К = 0.61–0.80), and two had almost perfect (К = 0.81–1.00) reliability. Of the 12 sedentary behaviour variables assessed for convergent validity, 7 were significantly correlated with children’s screen time, of which three were small (r ≤ 0.29), two were medium (r = 0.30–0.49), and two were large (r ≥ 0.50) effect sizes.

江西省高新技术产业与进出口贸易潜能分析

本文选取1995—2013年江西高新技术产业总产值和进出口贸易总额的时间序列数据,通过平稳性检验、协整检验和格兰杰因果关系检验,研究了江西高新技术产业与进出口贸易之间的关系。研究表明,江西高新技术产业对进出口贸易的发展有着较为显著的长期拉动作用,而进出口贸易对高新技术产业的影响则较微弱,本文在最后提出了相关对策建议。     

基于 GIS 和景观空间格局的区域耕地适宜度评价--以衡阳市松柏镇为例

该文利用景观生态学的研究方法,将耕地视为一种特殊的景观斑块,结合 GIS 技术对空间数据分析处理,利用 AHP 层次分析法,选取地形、水源条件、交通便捷性、空间布局等6个指标,建立了基于空间位置分布和空间地物相关关系的耕地适宜性评价体系,并以衡阳市松柏镇这一小区域耕地的适宜性评价为研究对象,为该区域的耕地治理、保护和合理开发提供依据.研究结果显示：松柏镇耕地斑块密度7.89,平均斑块形状指数1.6,总体聚集度指数82.07,表明该区域耕地总体表现为较为集中,不过耕地形状不规则,这对于机械化耕种有一定的不适性.通过 GIS 地理环境分析,最适宜的耕地有838.02hm2,占总耕地面积的39.22％,其所占比例最大,中等适宜的耕地有890.33hm2,占耕地总面积的34.98％,松柏镇耕地质量总体一般,部分耕地距离矿区很近,受到矿区重金属污染和大气污染较重.

川渝地区中学聋生课外阅读状况的调查与分析

课外阅读在聋生知、情、意的培养以及融入社会的过程中起着不可替代的作用。本研究主要采用自编问卷,调查川渝地区10所特殊教育学校401名初高中聋生的课外阅读状况。调查结果发现:川渝地区中学聋生课外阅读整体情况不佳,课外阅读期望和兴趣较高,而课外阅读氛围和物质条件较差,聋生认识到课外阅读的作用,但认为课外读物很难看懂;聋生对课外阅读有着较大兴趣,但阅读图书数量较少;聋生亟待养成良好的课外阅读习惯,每天阅读时间不足半小时;学校和家庭尚未给聋生提供丰富的课外阅读物质条件,也没有营造出浓厚的课外阅读氛围,尤其是家庭;聋生非常期望教师加强课外阅读指导,改善图书馆(室)状况。
