重大工程复杂性马尔科夫链—熵度量模型构建

本文利用马尔科夫链来理解重大工程的不确定性和动态演化特征,利用熵理论来量化重大工程的复杂性水平,建立了重大工程复杂性的马尔科夫链-熵度量模型。结果表明,重大工程的复杂性包括技术、环境、组织、目标、信息和任务六个维度,并具有结构性、不确定性和动态性特征。马尔科夫链可以用来描述过程,熵可以用来量化复杂性。该研究可以揭示重大工程的宏观状态与微观状态之间的关系,测度重大工程的复杂性水平,分析可持续发展趋势并进行预测决策和控制。

Time spent on the Internet by multicultural adolescents in Korea

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them.     

Establishing a ‘Centre for Engineering Experimentation and Design Simulation’: a step towards restructuring engineering education in India

Reforms in undergraduate engineering curriculum to produce engineers with entrepreneurial skills should address real-world problems relevant to industry and society with active industry support. Technology-assisted, hands-on projects involving experimentation, design simulation and prototyping will transform graduates into professionals with necessary skills to create and advance knowledge that meets global standards. To achieve this goal, this paper proposes establishing a central facility, ‘Centre for Engineering Experimentation and Design Simulation’ (CEEDS) in autonomous engineering colleges in India. The centre will be equipped with the most recent technology resources and computational facilities where students execute novel interdisciplinary product-oriented projects benefiting both industry and society. Students undertake two projects: a short-term project aimed at an engineering solution to a problem in energy, health and environment and the other a major industry-supported project devoted to a product that enhances innovation and creativity. The paper presents the current status, the theoretical and pedagogical foundation for the centre's relevance, an activity plan and its implementation in the centre for product-based learning with illustrative examples.

Epochē, Entertainment and Ethics: On the Hyperreality of Everyday Life

In this essay, I argue that popular entertainment can be understood in terms of Husserl’s concepts of epochē, reduction and constitution, and, conversely, that epochē, reduction and constitution can be explicated in terms of popular entertainment. To this end I use Husserl’s concepts to explicate and reflect upon the psychological and ethical effects of an exemplary instance of entertainment, the renowned Star Trek episode entitled “The Measure of a Man.” The importance of such an exercise is twofold: (1) to demonstrate, once again, the fecundity of the methodological procedures Husserl bequeathed to us; more than any other philosopher, he tapped into the fundamental manners in which we lose, make and remake the meanings of our lives; and (2) to demonstrate how popular entertainment, similarly, plays a central role in the making and remaking of the meanings of our lives. If my zig-zag procedure between Husserl’s philosophy and popular entertainment is productive and cogent, in addition to elucidating Husserl’s philosophy, it will demonstrate the reality-generating potency and the constitutive power of entertainment in the contemporary world. Entertainment, via ourselves, has become the primary producer of the meanings via which consciousness constitutes the world.     

分布式创新、知识共享与开源软件项目绩效的关系研究

开源软件是分布式创新下集体智慧的代表,知识共享是影响项目绩效的关键。本文对403份有效问卷进行大样本定量分析,研究影响开源软件项目内成员间知识共享的核心要素和机制。研究表明,以共享知识为中介的分布式创新影响开源项目绩效。其中,开发员作为供给端,从参与动机、社会网络、组织文化三方面;用户作为需求端,从用户创新角度共同对共享知识显著影响,进而影响开源项目绩效。薪酬刺激对于开源软件开发员的参与动机影响并不显著,打破了以往的认知误区。社会网络对成员间知识共享的影响程度最大。开源项目核心团队的管理能力胜于其技术能力,对项目绩效产生作用。用户创新对于促进开源软件项目绩效意义重大。     

高新技术项目投资风险的人工神经网络综合评价模型

高新技术项目投资具有高风险、高收益等特点，科学准确的风险评价对项目投资至关重要。在分析高新技术项目投资风险影响因素的基础上，并根据投资风险分级标准，建立了高新技术项目投资风险进行综合评价的人工神经网络模型，能有效地避免层次分析等传统评价过程中的人为影响。仿真实验表明，采用该方法能获得令人满意的结果。
