中国创新活动和经济增长的关系——一个基于协整理论的初步研究

内生经济增长理论告诉我们,创新活动作为技术进步的主要来源能够持续推动经济增长。但是中国现阶段经济发展条件下创新对经济增长的推动作用到底有多大,创新活动对于经济增长的影响机制如何,现有的研究并没有给出一个令人信服的答案。本文采用协整理论和误差修正模型研究了经济增长和创新活动之间的关系。研究结果显示,我国创新活动对于经济增长短期内具有显著影响,但其影响程度与长期影响相比还存在着较大差距;从长期看各种创新活动中基础研究能够实现对经济增长更大的推动作用。     

"有无"与"虚静"合一——从《老子衍》看王夫之对老子"有无"思维的研究

老子以"有无"境界,对人生实有领域的观照与觉悟,就是"虚静","有无"与"虚静"合一就是老子以境界形态的"有无"思维论证人生领域"无中之有"的"虚静"与"无"之境界的合一,这体现了老子境界形态"有无"思维的特征。王夫之以万物实有为思维起点,以实有形态的"有无",即:"有"与"有中之无"论"虚静",统一"有无"与"虚静"于"有"与"无中之有"的实有境界之中,从而从哲学思维的深度论证了"有无"与"虚静"合一于实有,即"有无"与"虚静"统一于"有"与"有中之无"合一的万物实有。

‘Colour-evasiveness’ and racism without race: the disablement of asylum-seeking children at the edge of fortress Europe

This article explores discriminatory discourses articulated by Italian professionals operating in educational, health and social services for refugees in Rome, in relation to the educational and social inclusion of unaccompanied asylum-seeking and refugee children. It locates such narratives within the historical ‘concealment and invisibilisation of race and racism’ that have characterised Italy particularly since the end of the Second World War, while showing how they legitimate contemporary processes of disablement and over-representation of forced migrant children in the category of Special Educational Needs. A theoretical framework influenced by Dis/ability Critical Race Studies, Italian postcolonial studies, and Judith Butler’s notions of subjectivation and performative politics is used to discuss how a ‘colour-evasive’ racial ideology has seeped into various institutions in Italian society, and importantly into education policies and practices.     

Modeling Synergy and Learning under Multiple Advanced Manufacturing Technologies

The advent of the wide variety of new, highly integrated, advanced manufacturing technologies available for acquisition by a firm's managers has brought to light an accompanying set of unexpected issues. These issues include expectations for the benefits and costs of these technologies, determining the appropriate order of implementation and finding a way to justify acquisition when many of the benefits are a function of the technology's learning and synergistic effects on other operations and technologies. We present here a model that captures the interaction effects of these highly integrated technologies and discuss the data requirements for application of the construct. We then illustrate the model's workings with a number of multitechnology examples and show the danger of ignoring the synergistic and learning effects of these technologies when considering their acquisition.     

Efficient Heuristics for MRP Lot Sizing with Variable Production/Purchasing Costs*

Two heuristics based on branch and bound (B&B) are developed to solve closed-loop material requirements planning (MRP) lot-sizing problems that have general product structures and variable costs. A “look ahead method'’(LAM) heuristic allows for variable production/purchasing costs and uses a single-level B&B procedure to rapidly improve lower bound values; thus, LAM efficiently uses computer-storage capacity and allows solution of larger problems. The “total average modification'’(TAM) heuristic uses B&B, applied level by level, and modified setup and carrying costs to solve the variable production/purchasing costs MRP lot-sizing problem. LAM and TAM are tested on problems and compared to heuristics in the literature. TAM may be used to solve large MRP lot-sizing problems encountered in practice.     

Integrating Analysis and Communication Skills into the Decision Science Curriculum*

The teaching of decision sciences presupposes that careful attention is directed toward improving students' critical thinking and analytical skills. This paper presents an approach to teaching quantitative methods classes that focuses on developing student skills in the areas of analytical and critical thinking through written and oral communication. The approach requires very little additional instructor preparation time and does not require the instructor to make major changes in either the content or organization of the course. While the instructor's investment is minimal, the benefits to the students appear to be substantial.     

Beyond “filling in the gap”: the state and status of Latina/o Feminist Media Studies

Against the socio-economic and cultural backdrop of the ongoing Latina/o media “boom,” this critical literature review delineates the location and status of contemporary Latina/o Feminist Media Studies. Departing from a critique of current mainstream Feminist Media Studies research and citational practices, it traces the influence of rapidly expanding transnational Latina/o media markets, the gendering of Latinidad, and transnational feminisms on recent Latina/o Feminist Media Studies scholarship. As it not only breaks with exclusively domestic analyses of intersectionality and accurately reflects twenty-first century media’s transnational orientation, this essay argues that the theoretical paradigms and thematic concerns of Latina/o Feminist Media Studies must ultimately be reframed as central, not marginal, to Feminist Media Studies research.     

Which Spouse Initiates Marital Separation When There Are Children Involved?

This report examines whether the presence of children in marriage differentially influences the risk of wives or husbands initiating separation. The analytic sample consists of 9,118 first marriages from the Households, Income and Labour Dynamics in Australia survey (2001). Using event history and competing risks analysis, I find weak evidence that wives are less likely than husbands to initiate when they have infants, and husbands are less likely than wives to initiate when children are school age or older. Overall, the results show that children deter marital separation for both wives and husbands, indicating that gender differences in the decision to separate are likely attributable to other factors such as a willingness to remain in an unhappy marriage.     

Communicative Correlates of Satisfaction,Family Identity,and Group Salience in Multiracial/Ethnic Families

Guided by the Common Ingroup Identity Model ( S. L. Gaertner & J. F. Dovidio, 2000 ) and Communication Accommodation Theory ( C. Shepard, H. Giles, & B. A. LePoire, 2001 ), we examined the role of identity accommodation, supportive communication, and self‐disclosure in predicting relational satisfaction, shared family identity, and group salience in multiracial/ethnic families. Additionally, we analyzed the association between group salience and relational outcomes as well as the moderating roles of multiracial/ethnic identity and marital status. Individuals who have parents from different racial/ethnic groups were invited to complete questionnaires on their family experiences. Participants (N = 139) answered questions about relationships with mothers, fathers, and grandparents. The results of the multilevel modeling analyses are discussed in terms of implications for understanding multiracial/ethnic families and family functioning.
