北京市老年人权益保障的探究

人口老龄化社会已经到来,老年人的各项权益频遭侵害,而老年人权益保障法仍停留在初级阶段,老年人权益保障制度还有待完善。本文以笔者参与调查的北京市老年人法律意识及权益维护现状调查问卷的数据资料为基础,在研究北京老年人权益保护现状过程中探索了老年人权益受侵害的原因及特点,提出了保障老年人权益的对策和建议,希望能对首都建设和谐社会有所裨益。     

论清代嘉道之际的汉宋之争与汉宋兼采

在中国学术、思想史上,汉、宋两学关系问题是一重要问题,到清代嘉庆、道光之时尤为引人注目。围绕这一问题,时人聚讼纷纭,其中以江藩、方东树在各自著作中所表达的针锋相对的理念及其所引发的学术风波最具影响力。这固然标志着所谓“汉宋之争”已达高潮,同时它也说明这一时期学术格局有所变化,即汉学虽仍居主导,但宋学的空间已越来越大。宋学空间的得以扩大,与当时学界存在的汉宋调和、汉宋兼采之风密不可分,汉学家与宋学家之间既相互贬抑,又彼此调和,兼采对方之长为己所用。这一切,预示着学术嬗变的契机已显现,学术演进将有新趋势。     

关于大学生素质教育创新的思考

随着21世纪知识经济的到来,加强和改进大学生素质教育已经成为一个重要课题。然而在素质教育的认识论和价值论依据方面,仍有许多问题需要澄清,这是素质教育的基础性问题。     

论虚实关系在舞美设计中的运用

虚与实是艺术创作技巧的美学原则,在舞台美术设计中,更显示出虚实结合的独特性和必要性,具体来说,表现在几个方面:在布景设置上,要以实带虚,以虚衬实;在意境表达上,要虚实对比,和谐产生;在光色处理上,要虚实变幻,以景托人;在舞台布局上,要讲究整体,统筹协调.

Multi-Item Grouping Algorithm Yielding Near-Optimal Logistics Cost

This article describes an algorithm used to formulate an inbound consolidation strategy when multi-items are replenished in groups and when total logistics cost is to be minimized. The importance of this algorithm is threefold (1) no optimal procedure exists for grouping multi-items when minimizing total logistics cost, (2) a complete enumeration of all possible groups (from which the optimal grouping set can be identified) is impractical due to the combinatorial nature of the grouping problem, and (3) no other heuristics have been developed that adequately reflect shipping cost in the analysis like this one does. We report the experience of using this algorithm to group and reorder 75 selected ensembles containing a total of 517 inventory items of a retail merchandising firm.     

Solution Procedures for the Lot-Streaming Problem

Lot streaming is the process of splitting a job into sublots so its operations can be overlapped and its progress accelerated. We present a computationally efficient procedure for solving the m-machine, two-sublot problem, and we discuss the bottleneck insights that emerge from the analysis. We also examine heuristic approaches for more than two sublots and discuss computational results for these procedures.     

On Sampling Error in Market Share Estimates*

The relative error in the usual estimator of a brand's market share is reformulated in terms of marketing parameters. Such error is shown to be influenced in an important way by market penetration, as well as by variation in brand and product category volume. Of particular interest is the result that the relative error does not depend on the actual share level. Using data from a marketing research firm that supplies share estimates to the health products industry, we find that the relative error may be substantial even when a large sample is available. An upper bound on this relative error is obtained using marketing parameters that can frequently be measured using industry data and a company's internal records, thus reducing the level of judgmental input required in the planning of sample surveys.     

Purpose and life satisfaction during adolescence: the role of meaning in life,social support,and problematic digital use

This study examined the characteristics of youth with different types of purpose in life, as well as the associations between adolescents’ life satisfaction, purpose in life, meaning in life, social support, and problematic digital use. The sample included 193 participants aged 14–18 who completed self-report questionnaires on life satisfaction, purpose in life, meaning in life, social support, and problematic digital use. The following purpose in life clusters were found: (1) other-oriented goals (n?=?33); (2) self-oriented goals (n?=?42); and (3) both other- and self-oriented goals (n?=?107). Adolescents with both self- and other-oriented goals had significantly higher life satisfaction, meaning in life, and social support compared to the other groups. Meaning in life and greater support from parents and teachers were significantly associated with greater life satisfaction. In addition, having other-oriented goals was associated with lower life satisfaction. Finally, support from parents (p?=?0.05) mediated the association between problematic digital use and life satisfaction. Findings are discussed in light of previous research and the theoretical and practical implications are examined.
