多媒体崇拜症：成因及对策

多媒体教学过程中出现了一系列的问题,这些问题从总体上可冠之为＂多媒体崇拜症＂。这种症状的产生成因复杂。其中既有特定时代背景下某些社会思潮的影响,如＂技术决定论＂的影响和技术使用上功利主义态度的影响;也有施教者和管理者素质上的不足,尤其是精神上的懒惰;更与当前大学的行政化办学体制有某种内在的关联。要克服这种症状,目前可做的工作重点是端正对多媒体使用的看法,提高多媒体使用的技术水平,并且在教学评价上要注重平衡。     

科技进步与北京社会阶层结构变动

自工业社会以来,科技进步引发深刻的社会阶层结构变动,改变着原有的社会分层体系。伴随着北京高新技术产业的发展,北京社会结构发生着深刻的变迁。研究表明,这一变迁突出表现在两方面:一方面,高新技术产业的发展,提高了劳动生产率,减少了劳动力投入,直接导致体力劳动者阶层在社会阶层结构中所占的比例规模不断减小,而脑力劳动者阶层规模不断壮大;另一方面,高新技术产业发展深刻影响着社会阶层结构中的资源配置,改变着原有的社会分层体系。

技术创新史的文化研究路径——近年来技术史研究的新动向

对国际技术史权威期刊<技术与文化>最近十多年来有关技术创新史的论文进行了综合考察,参照文学理论和史学研究的新进展,从整体上对这些研究的方法论进路作了"文化研究"的理论概括与定位,从而尝试性地思考了国外技术史家在技术创新史研究中是如何引入建构论作为技术史的解释范式,并通过改进该范式,从而推动技术史走向对技术创新的"文化研究"路径的.思考了该解释范式有待进一步解决的问题,对技术创新史的进一步研究进行了展望.     

Data availability in accounting research: Some evidence

The data availability policy of the American Accounting Association is examined to address two research questions: (1) Are data dependent results in The Accounting Review readily available for further inquiry and dissemination of accounting knowledge? (2) What are the potential factors that may account for the availability or the lack of data? Several potential factors including job rank, number of revisions before acceptance, source of data, and funding source are suggested to account for the lack of data availability. The results indicate that, in general, authors are not willing to make their data available to others. We conclude by suggesting some options that may ameliorate the situation.     

Incorporating knowledge management as HRD strategy: the case of a Korean electronics company

Abstract

There is no doubt that knowledge management is now a very dominant theme in modern enterprises. To survive and compete in a knowledge-based economy, companies must learn to manage and sustain their intellectual assets. As a number of practitioners have noted, human resources play an important role in the transition process to the knowledge-based economy. This transition process is characterized by participant-driven integrative teamwork for dealing with various tasks and issues in organizations. This article presents a case study of the development of human resources in the context of knowledge management, which is based on systems thinking, exploring the process of problematization. It is based on a Foucauldian approach to expose the social relationship of power, knowledge and subjectivization in the problem-solving practice.     

Assessment of Catastrophic Risk Using Bayesian Network Constructed from Domain Knowledge and Spatial Data

Prediction of natural disasters and their consequences is difficult due to the uncertainties and complexity of multiple related factors. This article explores the use of domain knowledge and spatial data to construct a Bayesian network (BN) that facilitates the integration of multiple factors and quantification of uncertainties within a consistent system for assessment of catastrophic risk. A BN is chosen due to its advantages such as merging multiple source data and domain knowledge in a consistent system, learning from the data set, inference with missing data, and support of decision making. A key advantage of our methodology is the combination of domain knowledge and learning from the data to construct a robust network. To improve the assessment, we employ spatial data analysis and data mining to extend the training data set, select risk factors, and fine‐tune the network. Another major advantage of our methodology is the integration of an optimal discretizer, informative feature selector, learners, search strategies for local topologies, and Bayesian model averaging. These techniques all contribute to a robust prediction of risk probability of natural disasters. In the flood disaster's study, our methodology achieved a better probability of detection of high risk, a better precision, and a better ROC area compared with other methods, using both cross‐validation and prediction of catastrophic risk based on historic data. Our results suggest that BN is a good alternative for risk assessment and as a decision tool in the management of catastrophic risk.     

技术进步对我国经济增长作用的实证分析

为考察改革开放以来我国技术进步对经济增长贡献份额的变化情况，选用1979—2003年的相关数据进行实证分析。研究表明，改革开放以来我国技术进步对经济增长的贡献率偏低，经济增长主要是靠资本投入和劳动投入（特别是资本投入）来拉动的。因此，今后应不断增强我国企业的技术吸收能力和自主创新能力，实现从粗放型增长方式到集约型增长方式的转变，增强技术进步对经济增长的促进作用。     

三螺旋混成组织视阈下的科学知识生产

多价知识观的提出改变了传统的强调科学知识生产过程特定要素或某个片段的视阈,内在地要求以集成性的观点来审视科学组织。在分析知识多价性与科学知识生产场域集成性关系的基础上,阐释了大学—产业—政府三螺旋混成组织是一种科学知识生产的集成性组织。它捕捉了科学知识生产过程中包含学术、市场和政策的多元重叠关系,使科学知识生产所需的资源、组织结构及运作过程都具有集成性特征。
