区域差异视角下城乡居民收入对消费需求影响的实证分析

拉动内需将成为后金融危机时代保持经济可持续发展的关键,而居民收入水平直接影响了消费需求,并且影响程度存在明显的区域差异。利用浙江省11个地市1995-2008年的面板数据,运用面板单位根检验和协整检验,从城镇和农村居民收入水平对消费总需求的影响出发进行实证分析。从长期来看,城镇和农村居民的收入水平对区域消费需求具有较大的正向关系;但对消费需求影响,各地城镇和农村居民收入水平存在明显差异。

鄂西生态文化旅游整合分析及对策研究

鄂西具有丰富的生态文化旅游资源和开发潜力。该区域生态文化旅游整合应以丰富的生态旅游资源为基础,以深厚的文化底蕴为灵魂,以发达的旅游产业为引擎,以文化旅游产品为纽带,以产品优势互补,市场互补为条件,加强区域间合作,形成大旅游、大市场和大产业,推动鄂西地区各类资源整合、经济结构调整和发展方式转变,以实现经济社会快速、协调发展。     

教育水平视角下的收入差距

借鉴人力资本理论,对收入函数进行了方差分析,用城镇地区不同收入等级家庭收入比值代表收入差距,从理论和实证的角度分析了劳动力教育水平对收入差距的影响,证实了教育水平对收入差距变动趋势的影响是二次的,收入差距随着教育水平的提高经历了扩大、减少到绝对减少三个阶段。因此,应从促进就业、引入平等竞争机制和发挥劳动力市场中介作用等方面,缩小我国的收入差距。

21世纪人类将全面进入信息时代,高校档案应加快档案信息化建设以适应社会发展,高校档案信息化建设是带有深刻变革意义上的科技创新。推进高校档案信息化建设,已成为档案工作发展的必然选择和迫切需要。     

低利用率文献的区域性合作储存探索

文献储存空间不足与长期以来积聚的大量低利用率文献占据大量馆藏空间的矛盾成为图书馆迫切需要解决的问题。目前我国处理低利用率文献的方式并不能从根本上解决问题。实践证明,合作储存低利用率文献已经成为图书馆解决空间问题的主流。合作储存不仅可以节省储存费用,而且可通过进一步揭示文献资源、聚合文献供应提升文献的利用率,同时也可为人类长久地获得这些文献资源提供可靠的保证。因此,我国图书馆应该根据现实情况构建两种区域性合作储存的模型。

Tackling the remaining attainment gap between students with and without immigrant background: an investigation into the equivalence of SES constructs

In England, students with immigrant background exhibit lower educational attainment than those without immigrant background. Family socioeconomic status (SES) helps explain differences in educational attainment, but a gap remains that differs in size for students with different immigrant backgrounds. While the explanatory repertoire for the remaining gap is broad, it has been neglected to comprehensively investigate whether family SES constructs are equivalent across students with different immigrant backgrounds. Using data from the first wave of the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU) for England (n = 4,315), the paper applies exploratory structural equation modelling (ESEM) to evaluate measurement invariance of family background constructs across students without and with immigrant background, specifically Pakistani/Bangladeshi immigrant background. Results suggest differences in the structure of family SES indicators across groups and in their association with educational attainment. Complementary variables are suggested to enhance family SES indicators. Findings are relevant to researchers investigating educational inequalities related to immigrant background.     

Assessment of Adoption Gaps in Management of Aflatoxin Contamination of Groundnut (Arachis Hypogaea L.)

Abstract

One of the major impediments for diversification of groundnut (Arachis Hypogaea L.) as food crop is aflatoxin contamination. The study was conducted with an objective to assess the adoption gaps in aflatoxin management practices of groundnut (AMPG) and the farmer's characteristics influencing these gaps. The study used an expost-facto research design and multi-stage random sampling. The data were collected from 180 respondents through interview schedule. For measuring adoption gap, knowledge of AMPG and perception of groundnut quality suitable scales were developed. The data were subjected to multiple regression analysis to know the characteristics, which influenced the adoption gaps in AMPG. The majority of farmers were in high adoption gap category, as most of the farmers had not adopted the harvest and post-harvest management practices. Farmers' characteristics such as knowledge, market orientation and innovativeness influenced the adoption gap significantly. These three variables put together explained 58% of variation in adoption gap. Based on the results, it is suggested to formulate strategies to increase the knowledge of farmers through various extension approaches. If the knowledge on AMPG is improved the adoption gaps can be reduced. The maiden research effort, shed light on the socio-economic dimensions of aflatoxin contamination and constraints for aflatoxin management at farmers' level. The study has significance for the policy makers, extension departments and groundnut farmers for production of quality groundnut.
