论人事保证的制度功能及我国的立法选择——兼评《劳动合同法》第9条

《劳动合同法》第9条在现有立法禁止劳动合同物的担保的基础上，进一步否定了人的担保，与很多国家以及我国台湾地区立法上的规定不同。从社会学和经济学的视角分析了人事保证制度的基本功能，客观评价了既存人事保证制度，在此基础上提出我国立法对现有人事保证制度不应该全盘否定，而应该扬弃，重新界定人事保证的内涵。     

整代数体函数的亏量

研究了一类具有v＋1个亏值的v-值整代数体函数，利用整代数体函数的级与特征函数及其亏值亏量的定义和性质，借助线性无关性、克兰姆法则、Jensen公式及对数导数定理进行分析推理，得出这类整代数体函数的所有亏量之和不超过v．     

Some results on optimality in models with heteroscedastic errors from partial optimum designs

This paper studies optimum designs for linear models when the errors are heteroscedastic. Sufficient conditions are given in order to obtainD-, A- andE-optimum designs for a complete regression model from partial optimum designs for some sub-parameters. A result about optimality for a complete model from the optimality for the submodels is included. Supported by Junta de Andalucía, research group FQM244.     

轻声的作用与语音修饰

作为一种重要的语音现象，仅从可区别词义及词性来解释轻声的存在因由是不能令人信服的。轻声在语流中的语音修饰作用所带给我们的审美感受使得它的存在有理有据。     

和谐社会建设中低收入群体社会心态的引导与调适

良好的社会心态既是构建社会主义和谐社会的一种内在要求，也是和谐社会建设的重要心理资源。在社会转型时期，由收入差距扩大引起的不公平感和社会生活中的焦虑感，使低收入群体遭受到物质和精神上的双层困扰，并产生政治上的冷漠心态和信仰上的迷茫，为此，需要在社会意识领域做好教育疏导工作，更要在社会存在领域做好良好社会心态的强本固基工作。     

大学英语语调交际功能的课堂教学研究与实践

大学英语课堂教学不能只注意学生英语语音，更重要的是在语音的基础上掌握语调及其功能。从学生语言运用能力的角度来说语调的教学比纯语音教学应该更重要，因为同一个单词或句子用不同的语调在同等交际背景下传递出的含义就会不同，有时还会是相反的含义。以语调的交际功能为出发点，运用语用学的相关理论，设计并分析了基于语调交际功能的英语课堂教学模式的实践，探讨了这种模式的可行性和有效性，以引起大家对语调教学的重新思考。     

可持续旅游扶贫开发模式研究——社区参与乡村旅游

在对乡村旅游、旅游扶贫和社区参与旅游发展相关概念内涵及研究进展阐述的基础上,着重分析了贫困乡村社区参与旅游发展的必要性和主要障碍,提出社区参与乡村旅游的一些思路,即发挥政府的主导作用,通过政策调控保障社区参与的主体地位,通过科学合理的利益分配政策框架确立社区居民参与的激励机制,提高社区居民的相关旅游知识及进行相关能力培训,提高非政府组织在旅游发展中的作用等。     

Consortium for Atlantic Regional Assessment: Information Tools for Community Adaptation to Changes in Climate or Land Use

To inform local and regional decisions about protecting short-term and long-term quality of life, the Consortium for Atlantic Regional Assessment (CARA) provides data and tools (for the northeastern United States) that can help decision makers understand how outcomes of their decisions could be affected by potential changes in both climate and land use. On an interactive, user-friendly website, CARA has amassed data on climate (historical records and future projections for seven global climate models), land cover, and socioeconomic and environmental variables, along with tools to help decision makers tailor the data for their own decision types and locations. CARA Advisory Council stakeholders help identify what information and tools stakeholders would find most useful and how to present these; they also provide in-depth feedback for subregion case studies. General lessons include: (1) decision makers want detailed local projections for periods short enough to account for extreme events, in contrast to the broader spatial and temporal observations and projections that are available or consistent at a regional level; (2) stakeholders will not use such a website unless it is visually appealing and easy to find the information they want; (3) some stakeholders need background while others want to go immediately to data, and some want maps while others want text or tables. This article also compares what has been learned across case studies of Cape May County, New Jersey, Cape Cod, Massachusetts, and Hampton Roads, Virginia, relating specifically to sea-level rise. Lessons include: (1) groups can be affected differently by physical dangers compared with economic dangers; (2) decisions will differ according to decision makers' preferences about waiting and risk tolerance; (3) future scenarios and maps can help assess the impacts of dangers to emergency evacuation routes, homes, and infrastructure, and the natural environment; (4) residents' and decision makers' perceptions are affected by information about potential local impacts from global climate change.     

转型时期中国城市社区经济类型、特征及发展

改革开放以来，适应经济社会的转型与变迁，中国城市社区经济逐渐兴起并在城市社区生活中日益发 挥着越来越重要的作用，类型多样、特点鲜明的城市社区经济不仅为社区建设与发展提供了强大的物质经济支持，而且 吸纳了大量的城市社区富余劳动力，从而有利于增强社区凝聚力，提高了社区整合程度，促进整个社会的和谐发展。为 此，一方面我们要切实转变思想、更新观念，实现传统社区经济向现代社区经济的转变，另一方面因地制宜，结合实际，不 断创新发展社区经济思路与模式，切实提高社区居民生活水平，同时，提高管理水平，积极推进社区经济发展。     

Domains of convergence for the EM algorithm: a cautionary tale in a location estimation problem

The EM algorithm is a popular method for maximizing a likelihood in the presence of incomplete data. When the likelihood has multiple local maxima, the parameter space can be partitioned into domains of convergence, one for each local maximum. In this paper we investigate these domains for the location family generated by the t-distribution. We show that, perhaps somewhat surprisingly, these domains need not be connected sets. As an extreme case we give an example of a domain which consists of an infinite union of disjoint open intervals. Thus the convergence behaviour of the EM algorithm can be quite sensitive to the starting point.
