文艺学中内容/形式范畴述论(1900～1949)

在20世纪前50年.形式一词从传入到学界对它的运用并专论内容和形式的关系,从不成熟到成熟,虽处在启蒙救亡的大语境中,却在学理上达到了令后50年惊叹的成就,给后世留下了宝贵的理论资源.尤其是向培良对这一对范畴的研究,既反对题材决定论,又反对单纯追求技巧的形式主义;既赞成内容与形式的不可分,两者都不能单独存在,又在整个的艺术创造活动中研究内容向形式的动态转化过程.但后50年学界对此并没有好好继承,究其原因,除了新中国成立后在文艺界长期贯彻<讲话>精神,政治倾向压倒学理倾向之外,也和学界对这些成果有意或无意的忽视有关.     

Ambidextrous Organizational Culture,Contextual Ambidexterity and New Product Innovation: A Comparative Study of UK and Chinese High‐tech Firms

Contextual ambidexterity is of paramount importance for new product innovation and organizational success, particularly in high‐tech firms operating in a dynamic environment. Whilst it is recognized that contextual ambidexterity is grounded in organizational culture, existing research has not crystallized what kind of organizational culture enables contextual ambidexterity and consequently new product innovation. In this paper, drawing on data from 150 UK and 242 Chinese high‐tech firms, we conceptualize ambidextrous organizational culture as a higher‐order construct consisting of organizational diversity and shared vision, and examine its impacts on contextual ambidexterity and consequently on new product innovation outcomes. Using structural equation modelling, we find significant relationships between ambidextrous organizational culture, contextual ambidexterity and new product innovation outcomes; contextual ambidexterity mediates the relationship between ambidextrous organizational culture and new product innovation outcomes. Our findings also suggest that the above relationships are robust in the UK–China comparative research context, and that contextual ambidexterity and new product innovation outcomes are dependent on business unit level heterogeneity (i.e. ambidextrous organizational culture and research and development strength) rather than industry or cross‐cultural differences.     

The empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior under Stein's loss function

For the hierarchical Poisson and gamma model, we calculate the Bayes posterior estimator of the parameter of the Poisson distribution under Stein's loss function which penalizes gross overestimation and gross underestimation equally and the corresponding Posterior Expected Stein's Loss (PESL). We also obtain the Bayes posterior estimator of the parameter under the squared error loss and the corresponding PESL. Moreover, we obtain the empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior by two methods. In numerical simulations, we have illustrated: The two inequalities of the Bayes posterior estimators and the PESLs; the moment estimators and the Maximum Likelihood Estimators (MLEs) are consistent estimators of the hyperparameters; the goodness-of-fit of the model to the simulated data. The numerical results indicate that the MLEs are better than the moment estimators when estimating the hyperparameters. Finally, we exploit the attendance data on 314 high school juniors from two urban high schools to illustrate our theoretical studies.     

The disaster relief and social work after the Wenchuan earthquake in Mainland China

ABSTRACT

This paper mainly focuses on the development of disaster social work in Mainland China and the intervention of social work in disaster relief. Before the Wenchuan earthquake and in the initial stage of post-earthquake, disaster social work was mainly based on individual psychotherapy; from the earthquake to the year of 2012 in which post-earthquake recovery and reconstruction was completed, the disaster relief began to emphasise community building and integration, while the basic framework for disaster social work was also established. Social workers begin to explore the new mode of developmental and localised disaster social work. By combining with the practical experiences from disaster social work, this paper tries to highlight the dilemmas confronting disaster relief in Mainland China and put forward some corresponding countermeasures and suggestions, which could improve the future disaster relief system in Mainland China.     

Acceptance of automation manufacturing technology in China: an examination of perceived norm and organizational efficacy

Abstract

With a shift to more automation technology, social acceptance of technology plays an important role in the manufacturing sector. To what extent this occurs, and affects the adoption of technology, has been less researched, but is important in deciding how such technology is introduced, and the nature of the shift from labour-intensive manufacturing to automation. This research applies the revised technology acceptance model (TAM) to examine the impact of social and individual antecedents on the acceptance of automation manufacturing technology. Survey data are collected from 258 Chinese manufacturers. Results suggest that perceived norms significantly affect organizational intention to use automation manufacturing technology both directly and via perceived usefulness; organizational efficacy explains the intention to use via mediating effect of perceived usefulness and perceived ease of use. This research is one of the first extending and applying TAM from individuals to organizations.     

Elementary renewal theorems for widely dependent random variables with applications to precise large deviations

Abstract

On the basis of Wang and Cheng (J. Math. Anal. Appl. 384 (2011) 597–606), this paper further investigates elementary renewal theorems for counting processes generated by random walks with widely orthant dependent increments. The obtained results improve the corresponding ones of the above-mentioned paper mainly in the sense of weakening the moment conditions on the positive parts of the increments. Meanwhile, a revised version of strong law of large numbers for random walks with widely orthant dependent increments is established, which improves Theorem 1.4 of Wang and Cheng (2011 Wang, Y., and D. Cheng. 2011. Basic renewal theorems for a random walk with widely dependent increments and their applications. Journal of Mathematical Analysis and Applications 384 (2):597–606. doi:10.1016/j.jmaa.2011.06.010.[Crossref], [Web of Science ®] , [Google Scholar]) by enlarging the regions of dominating coefficients. Finally, by using the above results, some precise large deviation results for a nonstandard renewal risk model are established, in which the innovations are widely orthant dependent random variables with common heavy tails, and the inter-arrival times are also widely orthant dependent.     

朝核危机的最新发展态势及未来发展趋势

朝核问题的复杂性和谋求解决的困难程度关键在于朝美两个主要当事国之间的敌对关系及相互间不信任。朝核危机依然是威胁地区甚至全球安全最重要的因素之一，根据朝鲜过去多变善变的情况，六方会谈的前景依然迷雾重重，因而朝鲜半岛和东北亚局势今后将经历一段不确定时期；最大的可能性是谈，通过六方会谈机制，以外交谈判方式，和平解决朝核危机，实现半岛无核化，是解决朝核危机最理想的结果，也是六方会谈所要达到的最高目标；影响这一“最高目标”的两个因素是美国新政府有无对朝“新思维”、朝鲜有无“弃核”的意志。
