浅谈宗教的作用

宗教现象之所以能伴随着人类历史长期地存在着 ,并将继续存在下去 ,就在于宗教自身有着为人们所需要的特定功能及其社会作用。科学地、实事求是地全面研究和阐明宗教的社会作用问题 ,是宗教学基本理论的重要内容之一。在人类社会发展中 ,宗教的社会作用是多层面的。其主要方面有宗教的政治作用、宗教的道德教化作用、宗教的文化传播作用和宗教的社会交往作用等     

Professional development laboratory: center for literacy and community services

We developed three Professional Development Laboratories: Centers for Literacy and Community Services that addressed four pressing needs in the current urban school crisis: the preparation of in-service teachers to be literacy specialists, the dire need for qualified teachers in urban settings, the professional development of uncertified urban teachers, and the literacy needs of the children and families these teachers serve. These centers were housed in three inner-city schools rather than at the university and thus were able to serve larger numbers of children. Since many of the teachers in these schools are novice or uncertified teachers, we offered on-site in-service courses in order to enhance their ability to help their students. By housing the Centers for Literacy and Community Services on site in the schools, we sought to reach students and families who might otherwise not be able to avail themselves of these services. Unique to this project was that our graduate literacy education students tutored students on site in schools, the university faculty worked alongside the graduate students, and both students and faculty provided services to enhance the professional development of teachers and administrators in the area of literacy. Additionally, this project was distinguished by the inclusion of a component designed to provide literacy education services to the families and caregivers of the children.

The detection of annual clusters in individual patterns of parasuicide

The anniversary model for the annual repetition of parasuicide (attempted suicide) is described. In order to demonstrate the existence of such effects in individuals, the Range Test for circular data is applied to data collected over a 2-year period from a specific case from the Edinburgh Regional Poisoning Treatment Centre. The use of this model in predicting future clusters of parasuicide episodes is then discussed.     

Statistical inference for fixed-effects partially linear regression models with errors in variables

Fixed-effects partially linear regression models are useful tools to analyze data from economic, genetic and other fields. In this paper, we consider estimation and inference procedures when some of the covariates are measured with errors. The previously proposed estimations, including difference-based series estimation (Baltagi and Li in Ann Econ Finan 3:103--116, 2002) and profile least squares estimation (Fan et al. in J Am Stat Assoc 100:781--813, 2005) are no longer consistent because of the attenuation. We propose a new estimation by taking the measurement errors into account. Our proposed estimators are shown to be consistent and asymptotically normal. Consistent estimations of the error variance are also developed. In addition, we propose a variable-selection procedure to variable selection in the parametric part. The procedure is an extension of the nonconcave penalized likelihood (Fan and Li in J Am Stat Assoc 85:1348--1360, 2001), which simultaneously selects the important variables and estimates the unknown parameters. The resulting estimate is shown to possess an oracle property. Extensive simulation studies are conducted to illustrate the finite sample performance of the proposed procedures.     

建国初华东区保存富农政策执行情况解析

新中国成立初期，中共中央针对新区土地改革制定了保存富农经济的政策。在实际执行政策过程中，华东区根据地方调查情况，较好地执行了保存富农经济的政策。华东区之所以能较好的执行保存富农经济的政策，是与华东区农村调查的客观情况和地方领导人主观思想两个方面分不开的。这为建国初华东区经济的迅速恢复和发展创造了条件。     

敦煌吐鲁番文书中衣物量词例释

量词是汉语的重要特征之一,大量的量词在魏晋南北朝时期产生,并且随着时间的推移和地域、阶层的不同,不断地发生变化.研究量词的语法功能及其形成的历史,在当今语言学界是一个热门课题,但对量词的历史发展研究尚有许多空白.在量词研究方面,中古及近代契约文书有着极高的语料价值,因为契约文书强调的是合同双方的数量问题,量词的使用非常广泛,而且用法灵活多样.我们主要以<中国历代契约会编考释>[1]为基础材料,以敦煌、吐鲁番文书为参考文献,对其中的一些衣物量词作溯本求源的考释工作.     

Nash讨价还价公平关切下基于低碳商誉的供应链联合减排与广告的动态优化与协调

基于Nash讨价还价理论构建公平效用体系,同时考虑产品低碳水平和低碳商誉具有动态变化特征,运用微分博弈理论与方法探讨了供应链成员的公平关切行为对分散决策下零售商广告策略和制造商减排策略的影响以及集中决策下的相关策略。通过对比发现,集中决策下产品的低碳水平更高,在此基础上,提出了双向成本分担契约,实现了供应链协调。最后通过数值仿真,对重要参数进行了敏感性分析,并验证了契约的有效性。研究发现：当制造商边际利润比较小时,制造商不会对减排进行投入;只有当满足一定条件时,制造商才会承担零售商的广告成本;制造商的公平关切行为不利于企业发展低碳经济;零售商适当地关注公平,有利于企业发展低碳经济;与分散决策相比,双向成本分担契约下制造商和零售商的效用以及利润现值均有所提升。     

京津冀城市群发展效率评价及空间格局研究CSSCI

本文借助京津冀城市群13个城市2009—2019年面板数据,运用超效率SBM、云模型、热点分析、趋同检验和GWR回归等方法,评价京津冀城市群发展效率,探究空间格局和驱动机理。结果表明:(1)京津冀城市群整体发展态势良好,先后经历“震荡期”和“提升期”;(2)城市发展效率存在“马太效应”,具有明显的高低分区,但整体提升明显,同时出现热点聚集和冷点四周分散的分布格局;(3)京津冀城市群发展效率的驱动因素存在空间异质性,对外开放程度、产业结构、基础设施建设对城市发展产生促进作用,资源禀赋地区随着资源红利消失对城市发展产生抑制作用。
