基于潜类别随机前沿的区域创新效率及其影响因素分析

运用可根据研究对象的潜在属性内生分组的潜类别随机前沿模型,采用1999-2012年中国各省区数据,研究各省区的创新效率及影响因素。结果表明:以人力资本水平和基础设施状况为条件变量,将全国各省区分成两个技术类别,分别有各自的技术前沿和函数形式,A类别中上海市的创新效率最高,B类别中河北省的创新效率最高;平均来看,各类的创新效率均呈上升趋势,贸易开放、产业结构和金融发展对创新效率均有显著的正向作用,同时创新效率在各类内部均存在俱乐部收敛。

Double trouble: work–family conflict and well-being for second job holders

The purpose of this study was to provide an initial investigation into the work–family conflict (WFC) experiences of individuals who hold a second job. Specifically, we proposed two opposing theoretical arguments regarding the relationship between WFC and four measures of well-being: life satisfaction, physical health, emotional exhaustion, and exercise for individuals who hold two jobs. In a sample of individuals working two jobs, we tested whether the effects of WFC arising from the first job and from the second job exerted an additive or interactive effect on employee well-being. Our results indicated that for emotional exhaustion, physical symptoms, and life satisfaction, the effects of WFC from two jobs are interactive; but that for exercise, the effects of WFC from two jobs are additive. In both cases, the additional WFC experienced as a result of working a second job contributed to the prediction of employee well-being over and above WFC from the first job. Results are discussed within the context of relevant theory, and suggestions are made for future research.     

Periodic integer-valued bilinear time series model

This paper deals with the study of some probabilistic and statistical properties of a periodic integer-valued diagonal bilinear model. The existence of a periodically strict stationary integer-valued process is shown. Sufficient conditions for the periodically stationary, both in the first and second orders, are established. The closed-forms of the mean and the second moment are obtained. The closed-form of the periodic autocovariance function is established. The Yule–Walker estimations of the underlying parameters are obtained. A simulation study is provided.     

美国文艺作品中阶级位移主题模式的嬗变

美国文艺作品中的阶级位移主题是一个未被学术界重视的边缘话题,在当下的文化语境中研究其主题模式的嬗变为我们提供了一个洞悉此类美国文学作品的崭新视角.根据拉梅耳(R.J. Rummel)的观点,梳理了文艺学视域内的阶级概念,以此标准定义出阶级位移的主题并归纳总结出美国文学作品中"堕落"与"成功"两个主题模式.纵览19世纪中前期到当代的涉及阶级位移的美国主流文艺作品,在历史与文化语境中勾画出此类作品嬗变的轨迹和特点,并从历史的角度分析其成因,指出女性和少数族裔人民的觉醒是推动阶级位移主题模式发展变化的内因.     

Geometric Anisotropic Spatial Point Pattern Analysis and Cox Processes

We consider spatial point processes with a pair correlation function, which depends only on the lag vector between a pair of points. Our interest is in statistical models with a special kind of ‘structured’ anisotropy: the pair correlation function is geometric anisotropic if it is elliptical but not spherical. In particular, we study Cox process models with an elliptical pair correlation function, including shot noise Cox processes and log Gaussian Cox processes, and we develop estimation procedures using summary statistics and Bayesian methods. Our methodology is illustrated on real and synthetic datasets of spatial point patterns.

“It Depends on How You Define Integrated”: Neighborhood Boundaries and Racial Integration in a Baltimore Neighborhood1

There are a significant number of racially integrated neighborhoods in the United States, many of which have been stable over time. However, very little is known about the characteristics of these neighborhoods and of the residents who live in them. With data taken from a larger study of an integrated neighborhood in Baltimore, Maryland, this article discusses homeowners’ perceptions of their community and racial integration. Fifty semi‐structured interviews were completed with 67 homeowners to investigate their perceptions and experiences of race, class, and change in their community. This study shows that statistical racial integration and perceptions of racial integration are two different factors. Residents define true racial integration as both residential and social. As a result, homeowners reported that their neighborhood is both segregated and integrated—a type of “qualified” integration. Perceptions of racial integration are also affected by inconsistently defined neighborhood boundaries and racial clustering, block by block.     

Self,Career and Nationhood: The contrasting aspirations of British and French elite graduates

There is increasing interest in the emergence of a ‘global middle class’ in which high achieving young graduates increasingly look to develop careers that transcend national boundaries. This paper explores this issue through comparing and contrasting the aspirations and orientations of two ‘elite’ cohorts of graduates. Interviews with students at the University of Oxford, England, and Sciences‐Po, France, reveal very different ambitions and allegiances. Our Oxford respondents portray their futures as projects of self‐fulfilment as they build portfolio careers by moving from job to job and from country to country with limited social allegiances – epitomizing the nomadic worker of the transnational elite. Our Parisian respondents, on the other hand, display strong allegiances to the nation, state and civic duty. Their projects of the self involve reconciling their personal aspirations with strong allegiances to France. The paper concludes by discussing the significance of these differences. It argues that the enduring role of education in the formation of national identities should not be overlooked and that more detailed research is needed on the contextual specifity of transnationalism and the (re)production of elites.
