The Fourth International Conference on Information and Management Sciences

作者： M.B.NEACE Mercer University MaconGAUSA

＜正＞ Social exchange theory is rich with dynamic analytical frameworks and research on socio-economic exchanges. We introduce a socio-economic paradigm in a vital sector of the economic life of China - small exporting entrepreneurs. Strong relationships between the concepts of social capital and economic exchange within network structures were found in the data collected from a sample of small exporting entrepreneurs. The analysis explored these relationships among strategic choices, social capital and economic exchanges within the network structures they were attempting to join - "creating" network gaps with established structures - holes - they would, in turn, fill/enhance. Two models are presented that are extensions of our previous work. By extending the holistic character of the models through the addition of network theory, social capital and information from the sample participants, led to the extension of the models, incorporating their holistic, or lack thereof, views of the networks （most often near the front end of a long supply chain）, the barriers they confronted, and the social capital necessary to become viable members of the structural networks.

The Journal of China Universities of Posts and Telecommunications 1994年第2期1卷 77-80页

作者： LiLin And LuJiajian(Departrnent of Telecommunication Engineering ,Xi’an instituteof Posts and Telecomrnunications Xi’an 71006, P. R. china)

This paper gives a new algorithm of harmonious decomposition of linear graph. It bases onthe degree of cconected linear graph. Comparing with the other existed algorithms, it can save twothirds of computation time. And it is more direct and zntuitive thon the other algorithms. It is more con-venient and quick to get the topofogical degrees of freedonz of linear graph- So it will have wide use inthe hybrid analyszs of electrical circuits. In the end of this paper we discuss an appltcalion example ofthe algorithm.

对于精神障碍这一概念的理解，传统DSM-ICD分类诊断系统和研究领域标准RDoC均基于潜变量视角，认为精神障碍的症状由其潜在共同原因所致。这2种观点都忽略了症状间的相互作用。不同于分类和维度视角，Borsboom在2008年对精神障碍的概念化提出了的全新视角——心理病理学网络理论。此理论的核心观点是症状之间的动态因果关系构成了精神障碍。基于心理病理学网络理论的网络分析方法，主要以结合EBIC的glasso算法估计症状间的偏相关网络，并通过网络中节点中心性与网络连接性等指标，来考查精神障碍症状的不同特性。近几年来，研究者发现心理病理学网络分析方法在对症状间因果关系的推断、核心症状的识别和网络结构的可靠性与可重复性方面仍面临一些挑战。这些挑战为心理病理学网络理论与方法指明了未来可能的发展方向。

Scale-Free Behavior in Weighted Stock network

Journal of Southwest Jiaotong University(English Edition) 2007年第3期15卷 242-246页

A weighted stock network model of stock market is presented based on the complex network theory. The model is a weighted random network, in which each vertex denotes a stock, and the weight assigned to each edge is the cross-correlation coefficient of returns. Analysis of A shares listed at Shanghai Stock Exchange finds that the influence-strength （IS） follows a power-law distribution with the exponent of 2.58. The empirical analysis results show that there are a few stocks whose price fluctuations can powerfully influence the price dynamics of other stocks in the same market. Further econometric analysis reveals that there are significant differences between the positive IS and the negative IS.

What Influences Cooperative Motivation of Foreign Brides From Southeast Asian Countries in Taiwan？

引用

Chinese Business Review 2012年第6期11卷 571-579页

作者： Chih-Chung Wang Chiu-Ping Chen Kaohsiung Medical University Chung-Ho Memorial Hospital Kaohsiung Taiwan I-Shou University Kaohsiung Taiwan

Because women in Taiwan have had more and more opportunities to receive higher education and engage in different kinds of work, they have had developed increasingly higher standards for their marriage partners. Men who are in the lower socioeconomic working classes such as those who work in agriculture, or fishing, or who are disabled can no longer compete in local marriage market. As a result, these men have begun to look for their brides from other countries to continue the family line, do the housework, and take care of their parents-in-law. In addition to the fact that these foreign brides are often young and from rural areas, language barriers and cultural differences make it difficult for them to raise and educate their children in Taiwan. The inability of these brides often leads to a higher percentage of children who are developmentally delayed, have poor pronunciation, behavior problems, and low academic achievement. Governmental agencies and schools recognize these issues and have tried to help foreign-born mothers take better care of their children. However, there are several influential factors that can limit the cooperative motivation of these foreign-born mothers, including language barriers, parenting stresses, low socioeconomic status, and cultural limitations. Therefore, governmental agencies and related professionals must take these factors into consideration to provide comprehensive services and a better learning environment.

Contextualized Analysis of Social networks:Collaboration in Scientific Communities

Social networking 2014年第2期3卷 71-79页

作者： Maria Teresinha Tamanini Andrade Patrícia Braga Tereza Kelly Gomes Carneiro Núbia Moura Ribeiro Marcelo A.Moret Hernane Borges de Barros Pereira Instituto Federal de Educacao Ciencia e Tecnologia Simoes FilhoBrazil Programa de Modelagem Computacional SENAI CimatecSalvadorBrazil Universidade Estadual de Ciencias da Saúde de Alagoas MaceioBrazil Universidade Estadual de Feira de Santana Feira de SantanaBrazil Universidade do Estado da Bahia SalvadorBrazil

Currently, the collaboration in scientific communities has been studied in order to explain, among other things, the knowledge diffusion. The quality of Graduate Programmes is often associated with the scientific collaboration. This paper discusses how scientific collaboration processes can be identified and characterized through social and complex networks. For this purpose, collaboration networks of bibliographic production, research projects, and committees of PhD theses and Masters’ dissertations by researchers from a graduate program in computational modeling were studied. The data were obtained from CAPES’ reports of the period from 2001 to 2009. Among the studied indices, centrality indices indicate the presence of prominent researchers who influence others and promptly interact with other researchers in the network. The indices of complex networks reveal the presence of the small-world (i.e. these networks are favorable to increase coordination between researchers) phenomenon and indicate a behavior of scale-free degree distribution (i.e. some researchers promote clustering more than others) for one of the studied networks.

Global Financial Crisis： Systemic Failure and the Underlying Knowledge Gap

引用

Journal of Modern Accounting and Auditing 2014年第9期10卷 950-958页

作者： Mir Obaidur Rahman United International University Dhaka Bangladesh

Recently, global financial crisis or meltdown rocked the international financial market. This havoc was the result of the reckless use of financial derivatives that received spontaneous patronization from the financial whiz, but it is strange to discover that those proponents of market economy embarked on policy that was purely Keynesian in principle. The episode started in August 2007 with the collapse of subprime mortgage market and reached its climax during August 2008. Central banks in many countries of the western world intervened in the market to pump additional fund to give buoyancy in the credit market. The crisis encapsulated with the queer idea of financial instruments and multiple origins related to subprime mortgage left its trail in both developed and developing countries. Thus, an elaborate analysis of the causal link among various innovative instruments highlighting a mismatch between academic doctrine and real-life perspective and the inadequacy of the institutional arrangements supposed to tame the volatility of the market may be a useful guide to financial analysts and policy planners. The purpose of this paper is to highlight systemic gaps in the meltdown and redefine the contour of macroeconomics most appropriate to weather such catastrophe in the future.

Mycorrhiza-mediated interplant nitrogen (N) movement could have important implications for nutrient biogeochemical cycling in both terrestrial and agricultural ecosystems. Research on ectomycorrhizal (EM) diversity has focused on conifer forests;we know less about more arid systems such as in California oak woodlands. Exotic annual grasses invaded California oak woodlands within the last 100 years replacing n-
