Adolescents' body‐tanning behaviours: influences of gender,body mass index,sociocultural attitudes towards appearance and body satisfaction

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research.     

后起国家技术寻求型OFDI机理研究:基于韩国的案例分析

利用国外的先进技术弥补本国技术上的不足,是后起国家加快技术进步实现现代化的基本路径。文章以韩国为例,研究了其从引进来到走出去的技术进步路径,结果表明,韩国技术寻求型OFDI具有始发于工业化中后期阶段、着眼于高新技术产业、主要面向发达国家和地区、以国内大企业为主导和得力于政府全方位积极推动的特征。在此基础上,对我国开展技术寻求型OFDI,提出要注重区域异质性、培育具有竞争力的大型企业集团、立足于高新技术产业,政府提供多方面的政策与服务支持等对策建议。     

税收对新疆居民收入分配影响的效应分析

Hicks theorem: Effects of technological improvement in the Ricardian model

Using the Ricardian model, we formally prove Hicks' [Hicks, John (1953), “An Inaugural Lecture,” Oxford Economic Papers 5(2), 117–135.] insight into the effects of technological improvement: uniform technological improvement at home benefits all countries (or at least does not hurt); export-biased technological improvement at home benefits the foreign country (or at least does not hurt), but import-biased technological improvement at home can hurt the foreign country as long as the comparative advantage is not reversed. We then study optimal strategies of technological improvement and show that for a small country it is optimal to choose export-biased technological improvement. For a large country, it is optimal to improve technology in both sectors at a rate proportional to the consumers' expenditure share. Therefore, if the expenditure share of the import sector is larger than that of the export sector, a large country will choose a relatively import-biased technological improvement, which will hurt its trading partner.

千帆竞逐"大家纺时代"

目前,在三大纺织最终产业--服装、产业用纺织以及家用纺织中,以家纺的发展最为显著,家纺纤维加工的比重已经达到发达国家水平.家纺产业从最初满足人们铺铺盖盖、遮遮淹掩与洗洗涮涮,到展示和体现人们的生活品味和情调,并成为中国纺织工业新的增长点.家纺产业之所以能取得如此发展,一是由于行业组织的整体规范和战略化思考有效的推动;二是依靠权威性展会来和产业互动,更重要的是家纺企业的努力和调整创新,因而才真正形成今天"大家纺"的发展格局.
