于根元先生的语言规划观

于根元先生的语言规划观主要体现在“语言规范观”“语言主体多样观”“语言服务观”三个方面。在语言规划研究方面,于先生提出了许多具有鲜明特色的重要命题,如语言规范的参照项是交际值、检验规范的成效是对语言生活的影响、语言规范制定时应重视语言的可预测性、规范就是服务等,这些命题如今看来,依然具有学习借鉴的理论意义和实践价值。     

农村公共服务供给中的公共性生产逻辑

农村公共服务供给的多主体协同是在共同体框架内进行的,农村公共服务供给共同体形成的关键在于其公共性。结构-文化-行动者的三维分析框架为农村公共服务供给共同体公共性的生产逻辑提供了解释。基于湖南湘西J村人居环境改善的案例研究发现,公权力对私权利的引导、规范纠偏与压制,科层体系下的权力控制以及集体主义优先于个人主义的道德结构是农村公共服务供给共同体公共性生产的压力来源;农村熟人社会对人情关系、公共空间对话和乡村精英的培育为该共同体公共性的生产提供了弹性空间;而个体行动者公共利益优先于个人利益的利益选择、参与型的意义建构和服务型的价值认同则促使其自主生产公共性。     

中国服务业高质量发展评价与实现路

服务业高质量发展日益成为经济高质量发展的重要题中之义。在充分梳理服务业高质量发展 文献的基础上,将服务业高质量发展解构为结构高质量、效益高质量、规模高质量、品牌高质量4 个部分, 进而构建了服务业高质量发展的评价指标体系。根据该指标体系对中国服务业高质量发展进行总体、分 类、分区测算,发现中国服务业高质量发展呈现总体上升、品牌迟滞、区域失调的态势。研究发现:中国服 务业可以通过结构优化、品牌再造、融合发展、协调共进四个路径来实现更优的高质量发展。本文的研究 是建构服务业高质量发展指标评价的有益尝试,对服务业高质量发展具有一定的政策启示。

Sampling from spatial databases

This paper deals with techniques for obtaining random point samples from spatial databases. We seek random points from a continuous domain (usually ²) which satisfy a spatial predicate that is represented in the database as a collection of polygons. Several applications of spatial sampling (e.g. environmental monitoring, agronomy, forestry, etc) are described. Sampling problems are characterized in terms of two key parameters: coverage (selectivity), and expected stabbing number (overlap). We discuss two fundamental approaches to sampling with spatial predicates, depending on whether we sample first or evaluate the predicate first. The approaches are described in the context of both quadtrees and R-trees, detailing the sample first, acceptance/rejection tree, and partial area tree algorithms. A sequential algorithm, the one-pass spatial reservoir algorithm is also described. The relative performance of the various sampling algorithms is compared and choice of preferred algorithms is suggested. We conclude with a short discussion of possible extensions.     

Gaining Competitive Advantages in Higher Education: Analyzing the Gap between Expectations and Perceptions of Service Quality

The research findings have provided several implications for higher educational institutions, managers, and leaders of decision-making processes throughout the world. Service quality, customer satisfaction, and behavioral intentions are global issues that affect all organizations, large or small, profit or non-profit, global or local. We are all influenced or discouraged, satisfied or dissatisfied with positive loyalty behavioral intentions or negative complaining reactions, propelled by the level of service quality received. This revised version was published online in July 2006 with corrections to the Cover Date.     

Cybernetic Risk Analysis

The Pearl Harbor case study reveals that risk analysis failure may be caused by any of a number of factors. However, the most important variables are system load, gain, lead time, and lag time. The dynamics of such cybernetic systems analysis constitute an important aspect in this regard. Four different risk management strategies, or organization designs, have been proposed in this paper. Each has a unique combination of the imputed variables and each has a unique cause of surprise, risk analysis failure, and crisis.     

On the effectiveness of cognitive feedback from an interface agent

The objective of this study was to determine the impact of task information (TI) provided by an interface agent during the idea evaluation and integration step of the problem formulation stage of the problem solving process. The effectiveness assessment was based on solving diagnostic decision problems in the domain of complex industrial machinery. Ten domain experts participated in this study. Decision support was provided by a case-based reasoning system. Findings suggest that TI provided by the interface agent had no effect on the decision maker's performance, nor on the associated cognitive effort. However, a verbal protocol analysis revealed that the ten subjects used the interface agent to verify their decision processes. The results and their implications are discussed with respect to current findings in the area of decision support systems.     

Adaptive Build-up and Breakdown of Trust: An Agent Based Computational Approach

This article employs Agent-Based Computational Economics (ACE) to investigate whether, and under what conditions, trust is viable in markets. The emergence and breakdown of trust is modeled in a context of multiple buyers and suppliers. Agents develop trust in a partner as a function of observed loyalty. They select partners on the basis of their trust in the partner and potential profit, with adaptive weights. On the basis of realized profits, they adapt the weight they attach to trust relative to profitability, and their own trustworthiness, modeled as a threshold of defection. Trust and loyalty turn out to be viable under fairly general conditions.     

制造企业服务业务扩展及其认知因素研究

制造企业的竞争越来越激烈,几乎所有的企业都要面对快速反应多变市场和应对价格压力的要求,面对越来越小的产品利润空间和越来越复杂的客户需求,本文从对工业服务管理文献分析和制造企业的调查研究入手,揭示了制造企业从纯粹的产品生产者向客户支持方案提供者发展的转移趋势.通过对瑞士和德国30多家机器和设备制造企业进行的调查研究,说明了服务业务对制造企业在开发财务、营销和战略机会上的重要作用,并对转移过程中服务业务的扩展过程进行了总结.结合具体企业实践,本文对制约制造企业扩展服务业务中在管理动机上的认知因素进行了分析和研究.结合中国加入WTO后,中国制造企业将全面融入国际竞争的背景,本文期望对中国制造企业的发展和竞争地位的提高提供理论和实践上的指导.
