关于中国移民社会定位及对华裔报纸依赖性关系的考察

文章依据传媒系统依赖性理论以及社会认同理论对华裔移民的社会定位及其对华裔报纸的依赖性二者的关系进行了考察。所涉数据来源于对265位现定居于澳大利亚的中国人的调查。结果显示,在社会定位的三个指标中,年龄成为依赖族裔报纸获取信息的一个确定标准。在调查参与者中,在祖国居住越久的人更倾向于阅读本国语言文字的报纸。而被调查者教育程度的高低并不是对族裔报纸具有依赖性的重要标准。这些发现揭示出在这个由新技术提供多样化信息来源的时代,我们应该对印刷媒体的任务进行更深调查。     

聚集效应、区位差别与区域经济增长

运用一个简单的生产函数,对我国各省区1991到2002年资金投入、人力投入、聚集程度、科技投入等的数据进行估算,可以发现,在此期间决定我国区域经济增长的因素仍然是劳动投入和资金投入的增加。为使区域经济协调发展,各区域应走新型工业化道路,国家应加大对落后区域的支持。     

Estimators of location based on Kolmogorov-Smirnov-type statistics

Two classes of estimators of a location parameter ø₀ are proposed, based on a nonnegative functional H₁^* of the pair (D₁^ø_N, G^ø_N), where and where F_N is the sample distribution function. The estimators of the first class are defined as a value of ø minimizing H₁^*; the estimators of the second class are linearized versions of those of the first. The asymptotic distribution of the estimators is derived, and it is shown that the Kolmogorov-Smirnov statistic, the signed linear rank statistics, and the Cramérvon Mises statistics are special cases of such functionals H₁^*;. These estimators are closely related to the estimators of a shift in the two-sample case, proposed and studied by Boulanger in B2 (pp. 271–284).     

The effects of children on the major dimensions of home-based employment

Using an ordinary least squares regression procedure and data from the NE-167 sample of home-based employment households, the effects of children on seven major home-based work dimensions, respectively, are estimated along with remaining work dimensions and a series of control variables. The findings show that having a child equal to or under 18 years of age reduces home-based work hours by 407 hours per year, which equates to 1 work day per week. The separate effect of a child under 6 years of age reduces work hours by 296 hours per year or about three-quarters of a work day per week. Being a male home-based worker offsets these children effects considerably compared with being a female home-based worker. Children in general are negatively related to large-scale businesses that hire employees or services. Younger children negatively affect the likelihood of being a home-based business owner and being involved in seasonal home-based employment.This article reports results from the Cooperative Regional Research Project, NE-167, entitled, At-Home Income Generation: Impact on Management, Productivity and Stability in Rural and Urban Families, partially supported by Cooperative States Research Service, U.S. Department of Agriculture, and the Experiment Stations at the University of Hawaii, Iowa State University, Lincoln University (Missouri), Michigan State University, Cornell University (New York), The Ohio State University, The Pennsylvania State University, Utah State University, and University of Vermont. Appreciation is expressed to You-Hyun Cho for the computer assistance needed to complete these analyses. Patsy Seilen and Justine Lynge were instrumental in formatting and stylizing this article to required guidelines.Her current research interests include household asset and debt formation, working families, and employers' benefits and home-based employment.

城市快速物流配送网络末端节点——前置仓选址研究

在城市快速物流配送需求不断增加以及用户要求更加个性化的背景下,城市快速物流配送存在配送不及时、效率低下等诸多问题。为了提高城市快速物流的配送效率,将前置仓作为城市快速物流配送网络的末端节点,直接将仓库下沉至最终用户,缩短末端配送距离。在考虑前置仓配送服务范围的前提下,运用引入了道路非直线系数的K-means聚类方法对前置仓的选址构建聚类模型,并利用IBM SPSS Statistics20软件对某市区范围内的前置仓选址进行实例分析与计算。     

提升天津市区位竞争力的战略思考

确立以城市区位竞争力为导向的发展战略，进一步提升城市综合竞争力，对经济发展具有重要意义。通过与全国23个典型城市的对比，运用因子分析法，对天津市区位竞争力进行了深入分析与评价。分析结果显示，天津市的综合区位竞争力排名比较靠前，但除经济区位优势外，在交通区位、资源区位和政治文化区位方面的优势并不明显。根据分析结果提出了提升天津市区位竞争力的战略思考。     

单一出厂定价制度下区位假设与厂商选址决策

本文修改Hotelling（1929）模型的基本假定，假定厂商边际生产成本为正，交通成本由消费者负担，厂商区位可以为内生变量，也可以为外生变量，在此假定前提下，分析厂商的最优的区位一价格策略，以探讨最大差异化原则或者最小差异化原则何时成立，或者不成立。     

中国舞蹈专业院校教育现状与对策研究

中国现代意义上的专业舞蹈学校教育,是从1954年9月6日成立北京舞蹈学校开始。但是,由于当时的历史原因,受前苏联的影响,一开始就走向了"早期专业型人才"的培养模式,其教育目的非常明确,就是"为适应全国文化建设的需要,培养具有全面表演能力的舞蹈演员和教员"。这种单一的办学定位,虽然对培养"高、精、尖"舞蹈人才具有重要的保证作用,但是,随着经济改革的进一步深入,社会需求和人的需求的多样化,也逐渐暴露出其自身的不足与缺陷,如此继续发展下去,对学科的发展、人才的培养会产生极其消极的影响。为此,必须调整其办学思路,明确办学定位,适应社会发展,满足社会及人的需求。
