ABSTRACT

The aims of this study were to identify profiles of sedentary behaviour (SB) patterns, based on leisure-time self-reported SB modalities (screen, educative, social, and relaxing) and to evaluate changes in these profiles over 2 years among Spanish youth aged 8–18 years. Latent profile analysis (LPA), a data-driven analytic approach, was used to identify groups of boys and girls (n = 1553; 48% girls; mean±SD age: 12.56 ± 2.49 y) with distinct SB profiles using the SB modalities (time/d) as input variables. Latent transition analysis, an extension of LPA that uses longitudinal data, was used to analyse 2-year changes in these profiles. At baseline, four and three SB profiles were found among boys (labelled: screen, educative, social, and relaxing) and girls (labelled: screen/social, educative, and relaxing), respectively. Overall, more girls (range: 48%-67%) had the same profile over time, than boys (40%-52%). Participants with a screen or relaxing SB profile at baseline were more likely to have an educative profile after 2 years. Youth with a social and an educative SB profile at baseline were more likely to transition to profiles characterized by higher screen and social SB, respectively. Using a novel and person-centered approach, this study identified gender-specific SB profiles that were moderately stable over time.  相似文献

清末民初小说摭谈     

林骅 《天津师范大学学报(社会科学版)》2004,(1):62-66

清末民初的社会转型给小说园地带来了革命性变化,短短十余年间涌现的新小说,相当于此前一千多年产生的通俗小说的十余倍。而且名目繁多,内容深广,用嘻笑怒骂之笔,揭露了病入膏肓的社会疮痍,并努力探索富国强民的改革之路。这是一部形象的中国近代史,也是小说家们救亡图强的心史。在小说发展史上,新小说具有新旧更迭、革故鼎新的桥梁作用,从这个意义上说,它们是现当代小说的先声。  相似文献   

转型期我国有效体育需求不足问题研究   总被引：6，自引：0，他引：6  

刘卫  宋君臣  韩军梅 《山东体育学院学报》2005,21(2):21-23,37

运用问卷调查及资料分析的方法研究转型期我国有效体育需求发展的水平及社会经济环境。结果表明，转型期虽然我国的有效体育需求水平呈总体上升趋势，但体育消费额占居民收入和消费总支出的比例还很小，整个体育产业对GDP的贡献是很有限的。加快完善社会保障体制的步伐，努力提高低收入者的可支配收入，增强居民的体育消费意识，完善体育市场服务体系，政府运用税收手段调节体育商品供给是提高我国有效体育需求的有效手段。  相似文献   

Arts sponsorship and the state of the city     

Volker Kirchberg 《Journal of Cultural Economics》1995,19(4):305-320

This paper explores the correlation between metropolitan social and economic conditions and corporate arts support in the United States. It is hypothesized that the transition from a manufacturing sector economy to an advanced service sector economy is an important local factor for the increase in corporate arts support.By panel analysis, in eleven metropolitan areas between 1977 and 1991 changes in corporate arts support have been correlated with changes in social and economic conditions, i.e., service sector and manufacturing sector employment, service sector and manufacturing sector income, population's educational attainment, and the degree of dominance by the leading local arts supporting industry.Corporate arts support is higher in metropolitan areas where the population is better educated (=+0.60), the local service sector generates more income (=+0.37) and the local manufacturing sector generates less income (=–0.22).Corporations from the manufacturing sector are mostly indifferent towards arts support. In contrast, corporations from the service sector are supportive of the local arts but they also respond swiftly to a loss in their earnings by discontinuing their arts support.  相似文献
