浅圆仓环流降氧工艺研究

本文主要对环流充氮工艺进行研究,结果表明：以氮气95%和98%两种浓度比以90%、95%和98%三种浓度进行阶段环流充氮可以节能40%左右;氮气浓度95%保持35天能够抑制锯谷盗、赤拟谷盗和书虱等的生长发育甚至死亡;在密闭保持期间氮气在粮堆中以相似的速度进行自由扩散,而且当仓内氮气浓度大于95%后继续进行补氮成本将大幅增加。

基于“乡村特色”为核心的乡村旅游开发研究

乡村旅游在我国近20年的发展,已成为支撑旅游业发展的一支重要力量。乡村旅游吸引游客的是一个新奇的"农"字,也就是"乡村性"这个最基本的特征。但是乡村旅游低水平同质化的发展现状,却影响了乡村旅游的可持续发展。要突破这个困境,乡村旅游开发中,就必须基于"乡村特色"这个核心,发挥它在乡村旅游开发中的积极作用。

经济转型时期江苏省吸引FDI的现状与建议

通过对经济转型时期江苏省利用外资的现状分析,基于EG协整检验,本文对江苏省吸引外商直接投资的影响因素展开实证研究,分析结果表明江苏省原有的土地和劳动力优势已弱化,而高技术人才对吸引FDI和经济发展的影响显著,经济开放度对吸引外商直接投资也有影响,最后从产业、教育和港口建设等方面对江苏省在经济转型期吸引外商直接投资提出相应政策建议。     

Relationships among healthy lifestyle beliefs and body mass index in urban China

Consumption is a major driving force in China's economy. The consumer society is particularly emerging in the more urbanized and affluent regions in China. Given the rise of consumerism on the one hand, and the rise of overweight and obesity on the other, this study explored whether the proliferating consumer culture is a threat to the traditional health culture in China. The lifestyle‐oriented approach used in this study does not confirm a straightforward relationship between an upward trend in Chinese with (economic) assets to join the consumer society and a downward trend in health interest among urban Chinese. The result that the rise of the consumer society is not directly accompanied by a devaluation of health issues does not imply that lifestyle research is of no use. On the contrary, this paper successfully identified four dimensions of health‐related lifestyle for urban China, namely Food‐health Belief, Perceived Knowledge, Health Careless and Group Conformity. This result is informative with respect to the complexity of sociocultural factors influencing the increasing prevalence of overweight and obesity.     

Materialism and conspicuous consumption in China: a cross‐cultural examination

With the growing rise in consumer spending and economic power in Asian societies, it is increasingly important to explore the implications of these developments on consumer culture. This cross‐cultural study first discusses the rise of materialism and conspicuous consumption in post‐revolution China then examines differences in these phenomena between young adult consumers, aged 18–35, living in urban China and the United States. Utilizing survey data from over 600 respondents, significant differences were found in both materialism and conspicuous consumption, with Chinese young adults scoring higher in both variables. The findings show, that compared with past comparative studies, it appears both materialism and conspicuous consumption are on the rise among urban Chinese consumers.

婴幼儿食品微生物及微生物毒素调查分析

对婴幼儿食品（配方乳粉、补充谷物、饼干和罐头）分别进行微生物污染以及微生物毒素调查。调查结果表明：357份婴幼儿食品均未检出沙门氏菌和单核细胞增生李斯特氏菌;11份婴幼儿配方乳粉、1份补充谷物和1份饼干食品中检出坂崎肠杆菌,检出率分别为4.2%,2.4%和2.5%;检出1份补充谷物菌落总数超过国家标准最高安全限量值。13份婴幼儿配方乳粉和3份补充谷物检出肠杆菌科细菌,检出率分别为32.5%和7.1%;14份（婴幼儿）配方乳粉、2份婴幼儿罐头检出蜡样芽孢杆菌,检出率分别为35%和20%;1份婴幼儿配方乳粉检出黄曲霉毒素M1超标。婴幼儿食品存在微生物及其微生物毒素污染的风险,应加强对婴幼儿食品的致病微生物及其毒素的监测和监管。
