原生态文化中孑遗的黎族记忆

本文试从黎族的几类特征鲜明的原生态文化——宅居、服装、歌舞、图腾、纹身等方面挖掘这个民族的记忆,以期让更多人的了解黎族,走近黎族,并推动黎族文化走出海南、走向世界。     

Balanced consistency and balanced cost reduction for sequencing problems

We investigate the implications of balanced consistency and balanced cost reduction in the context of sequencing problems. Balanced consistency requires that the effect on the payoff from the departure of one agent to another agent should be equal between any two agents. On the other hand, balanced cost reduction requires that if one agent leaves a problem, then the total payoffs of the remaining agents should be affected by the amount previously assigned to the leaving agent. We show that the minimal transfer rule is the only rule satisfying efficiency and Pareto indifference together with either one of our two main axioms, balanced consistency and balanced cost reduction.     

上海机器人产业发展战略与对策

政府购买居家养老服务的探索与发展——以济南市历下区为例

基于济南市历下区购买居家养老服务的实践,探讨了社区居家养老服务的时代背景,重点分析了历下区政府购买居家养老服务的运作模式,研究结果表明,在我国养老压力日益严峻的情况下,要完善政府购买居家养老服务模式,必须积极推进社区居家养老服务产业的发展;加大政策扶持力度,加强资金引导;培育社会组织,提高养老服务品质;实现政府购买居家养老服务的标准化运作,只有这样才能缓解养老压力,提高老年人生活质量,推动养老服务事业的发展。     

疾病、文化抑或其他?——同性恋研究的人类学视角

客观存在的同性恋群体长期以来属于人类学研究的禁区,其承受的污名和歧视使触碰这一领域的学者规模和作品数量相对稀少,这种情况在中国人类学界尤为明显。从学科认识论来看,同性恋研究经历了"性逆转"、"性倒错"的医学范式;异性恋框架主导的文化影响模式;建构学派的历史、政治、经济视角批判;以及酷儿理论的全盘颠覆和开放式探索。     

城市农民工随迁子女义务教育政策及其完善：以广东为例

文章分析了广东省农民工随迁子女义务教育改革政策和实施情况。广东省基本实现了农民工随迁子女“人人有书读”,但是,农民工随迁子女入读民办学校的比例依然较高,入读公办学校的歧视依然存在,民办学校的教育质量问题依然存在。农民工随迁子女义务教育问题不能彻底消除,根本原因是没有建立起农民工随迁子女义务教育经费的投入保障机制。     

A usability gap between older adults and younger adults on interface design of an Internet-based telemedicine system

Internet-based telemedicine is becoming an effective tool to deliver home-healthcare services and health information on demand, especially in rural areas, where there is often a large elderly population with greater rates of preventable chronic diseases. However, the designs of current interfaces for these internet-based telemedicine systems do not take elderly user characteristics into consideration. This study conducted usability testing on the interface of an internet-based telemedicine system using two different age groups, young adults and older adults. Differences in overall performance and satisfaction between the two groups were identified. Based on these results, a future direction is suggested for the interfaces of Internet-based telemedicine systems.     

An optimal online algorithm for the parallel-batch scheduling with job processing time compatibilities

We consider the online (over time) scheduling on a single unbounded parallel-batch machine with job processing time compatibilities to minimize makespan. In the problem, a constant \(\alpha >0\) is given in advance. Each job \(J_{j}\) has a normal processing time \(p_j\). Two jobs \(J_i\) and \(J_j\) are compatible if \(\max \{p_i, p_j\} \le (1+\alpha )\cdot \min \{p_i, p_j\}\). In the problem, mutually compatible jobs can form a batch being processed on the machine. The processing time of a batch is equal to the maximum normal processing time of the jobs in this batch. For this problem, we provide an optimal online algorithm with a competitive ratio of \(1+\beta _\alpha \), where \(\beta _\alpha \) is the positive root of the equation \((1+\alpha )x^{2}+\alpha x=1+\alpha \).     

SOR视角下组织学习对组织创新绩效的影响

Ｒ2 是最近十几年迅速发展的一个研究课题,其研究取向从纯粹的计量经济学符号演变为股价同步性特征变量,并与公司特质信息含量联系起来,赋予了全新的内涵． 学者们通过跨学科的交叉与融合,从法与金融理论、委托代理理论、信息不对称理论、公司治理理论等视角对Ｒ2 背后的生成机制、作用渠道和影响后果展开富有成效的研究． 本文首先梳理从资产定价模型到 Ｒ2 ,再从 Ｒ2 到股价同步性中间的学理关系和因果顺承,接着回顾了关于 Ｒ2 形成机理与经济后果的相关讨论,然后对Ｒ2 的学术争论进行总结和评述,最后就Ｒ2 的溯源问题、以及文化与政治潜在影响对未来 Ｒ2 研究提出展望．
