Existence and global exponential stability of equilibrium of competitive neural networks with different time scales and multiple delays     

Haibo Gu  Zhidong Teng 《Journal of The Franklin Institute》2010,347(5):719-731

In this paper, some sufficient conditions are obtained for existence and global exponential stability of a unique equilibrium point of competitive neural networks with different time scales and multiple delays by using nonlinear Lipschitz measure (NLM) method and constructing suitable Lyapunov functional. The results of this paper are new and they complete previously known results.  相似文献   

A Post/Decolonial View of Race and Identity Through the Narratives of U.S. International Students from the Global South     

Nilanjana Bardhan  Bin Zhang 《Communication quarterly》2017,65(3):285-306

Using postcolonial and decolonial theory as a framework, this study focuses on the lived experiences of international students of color entering the United States for the first time in their lives from the global South. Our goal was to understand how they communicate/perform their dis/located identities in relation to “race” when immersed for the first time in a White settler society context. Findings from this qualitative study underscore discomfort with U.S.-centric race logics, production of ambiguity in relation to identity and race, and the growth of compassion for cultural Others as a result of becoming racial Other. The decolonial implications of such dis-identification with U.S. colonial race categories are discussed.  相似文献   

The changing status of higher education in the ‘moronic inferno’     

Melissa Johnson Morgan 《Perspectives: Policy and Practice in Higher Education》2017,21(4):144-149

Getting a good and relevant education is difficult enough to achieve within a context where social and economic needs are constantly unsettled by political policy. The public funding of the education sector has become a contested arena irrespective of a government’s ideology. Recent graduates from various disciplines from Town Planning to Philosophy report in university destination surveys that they have only found employment in areas unrelated to their academic training – for instance, in supermarkets, restaurants and other low-level service industries. How has it happened that the universalisation of mass higher education has contributed to a disconnect between the individual’s social aspirations and their economic status? What happened to the tacit promise that an extended period of intellectual development would prepare the individual for a life of valuable social contribution and financial security? Part of the answer lies in the success of higher education itself. Its popularity has changed its transformative capacity and allowed operational efficiencies to overrule academic quality. The university, ideally seen as a repository of intellectual intuition, has been remade into yet another modern corporation concerned with the bottom line and financial security. Why has it been necessary to remake the university in the image of the department store, supermarket or bank, and how has it been achieved without more critique?  相似文献   

全球变化对我国脆弱生态区经济开发的影响   总被引：5，自引：3，他引：5  

冉圣宏  唐国平  薛纪渝 《资源科学》2001,23(3):24-28

脆弱生态区是指对环境因素的改变反映敏感、而维持自身稳定的可塑性较小的生态环境系统,内部结构的不稳定性和对外界干扰的敏感性是它的两个最主要的特征。全球变化和经济开发活动是对脆弱生态区产生影响的最重要的两种外界干扰活动。全球环境变化会严重影响脆弱生态系统的结构,并进而影响到其经济开发活动。目前我国生态环境急剧恶化,全国脆弱生态区的面积占国土总面积的1/5,且其中的北方地区为全球变暖的高敏感区,因此讨论全球变化对我国脆弱生态经济开发的影响具有重要的现实意义。该文在前人工作的基础上,结合我国生态环境的现状、特点及全球变化对我国脆弱生态区的影响,利用国际应用系统分析研究所发展并改进的农业生态地带模型（AEZ).评估了全球变化对我国土地生产潜力的影响,分析了全球变化对我国脆弱生态区经济开发活动的可能影响,并对其适应性特别是全球变化背景下我国脆弱生态区的经济开发对策进行了探讨。  相似文献   

Taiwanese IT firms’ offshore R&D in China and the connection with the global innovation network     

Shin-Horng Chen 《Research Policy》2004,33(2):337-349

Although it is evident that technology is becoming increasingly globalized, resulting in the expansion of R&D internationalization by firms, despite this discernible trend, the substantial body of literature in this area is based mainly on the experience of the developed country. This paper aims to contribute to the understanding of this issue by examining the R&D internationalization of a newly-industrializing country, Taiwan being a prime example, and its connection with the global production network. We begin with an examination of the literature on R&D internationalization and globalization, based upon which we propose a conceptual framework adapted from Dunning’s eclectic paradigm. In doing so, we set out to develop arguments based not only on the reasons why cross-strait R&D internationalization may be undertaken by Taiwanese information technology (IT) firms, but also the likely patterns of their R&D portfolios across the strait. Drawing on an original questionnaire survey and firm-level interviews, the paper presents and discusses empirical data on the cross-strait R&D deployment of Taiwanese IT firms. It then goes a stage further, using the ‘smiling curve’, to put forward a ‘holistic’ view of the cross-border innovation network in the IT hardware industry, in order to determine what cross-strait R&D internationalization means to the global production network.  相似文献
