对创新高校思想政治理论课实践环节的思考

思想政治理论课实践教学环节是理论课教学体系的重要部分,是提升教学效果的有效途径之一。目前,实践教学存在着思想认识上有偏差、缺乏规范有效的组织管理、缺少资金和基地保障、缺乏科学的考核和评价体系等诸多问题,需要通过转变观念、建立和完善组织管理机制、设立专项经费和实践基地、建立健全实践教学评价体系等途径,使理论课实践教学更具有可操作性和实效性。     

论辞格理论与辞格发展之间的互动

古代修辞理论与辞格发展之间存在着复杂的互动关系。本文通过个案分析,证实了三点:其一,辞格的发展、演变本质上依赖于语言、文体本身提供的可能性,辞格理论的影响只是在发展方向上的诱导,并且这种诱导并不是总能成功;其二,这种诱导以理论被辞格使用者认同为前提,而特定文化背景或文学思潮可增强这种认同感,从而强化诱导;其三,当辞格使用者面对关于这一辞格的不同的甚至对立的理论主张时,他们会作出折中或取舍;而理论创造者面对辞格的发展变化,也有可能作出新的概括或补充。     

“联系说”视角下商标俗称抢注案的法律思考

商标权的客体为相关公众所认知的商标与商标所标识的商品或服务之间的联系,以此为基础可以认定商标俗称的抢注构成对商标权的侵犯,同时,商标俗称可以被认定为近似商标的一种形式,从而适用《商标法》第52条的规定。此外,在商标俗称的问题上,不能适用法律对驰名商标的特殊保护。     

Path(ological) Dependency? Core Competencies from an Organizational Perspective

The development of the 'resource-based theory of the firm' has helped to reorient the field of strategic management towards a focus on the organizational processes and structures which produce 'core competencies'. By challenging previous assumptions of market determinism this approach seems to open up the prospect of a greater dialogue with the theories and concerns of organization studies. This paper aims to determine the scope of such a dialogue by developing an appreciation and critique of the core competencies framework from an organizational perspective. In this context, the key feature of resource-based theories is seen to be their focus on organizational knowledge rather than decision-making processes as the engine of competitive performance. This focus has a powerful resonance with studies of knowledge in organizations, particularly those forms of knowledge which are linked to product and process design.
However, despite the important shift towards a knowledge-based view of competition, the core competencies approach fails to follow the logic of its own argument as far as the organizational appropriation of knowledge is concerned. In their pursuit of an ontological model of competitive performance –defining the essential causes of firm competitiveness – resource-based approaches neglect the socially embedded qualities of organizational knowledge. As a result, the social construction of knowledge, encompassing the dilemmas posed by the employment relationship and the pitfalls of institutionalization, is neglected. Instead, a smoothly linear model is developed linking skills, competence and competitiveness. This mechanistic view is further reinforced by reliance on a command and control model of the management process. Organizational knowledge is not a biddable resource at the disposal of top management.

静电电子回旋脉塞的单粒子理论

本文用单粒子理论研究了静电电子回旋脉塞。通过对静电电子回旋脉塞中的电子运动的分析,导出了电子与波互作用的非线性摆方程。文中用二阶扰动方法求解非线性摆方程,得到了TE_(mn)和TM_(mn)两种工作模式的静电电子回旋脉塞不稳定性线性增益公式,进一步证实了静电电子回旋脉塞不稳定性是存在的。     

Consistency of maximum likelihood estimators in a large class of deconvolution models

We consider the maximum likelihood estimator $\hat{F}_n$ of a distribution function in a class of deconvolution models where the known density of the noise variable is of bounded variation. This class of noise densities contains in particular bounded, decreasing densities. The estimator $\hat{F}_n$ is defined, characterized in terms of Fenchel optimality conditions and computed. Under appropriate conditions, various consistency results for $\hat{F}_n$ are derived, including uniform strong consistency.

Extended generalised Pareto models for tail estimation

The most popular approach in extreme value statistics is the modelling of threshold exceedances using the asymptotically motivated generalised Pareto distribution. This approach involves the selection of a high threshold above which the model fits the data well. Sometimes, few observations of a measurement process might be recorded in applications and so selecting a high quantile of the sample as the threshold leads to almost no exceedances. In this paper we propose extensions of the generalised Pareto distribution that incorporate an additional shape parameter while keeping the tail behaviour unaffected. The inclusion of this parameter offers additional structure for the main body of the distribution, improves the stability of the modified scale, tail index and return level estimates to threshold choice and allows a lower threshold to be selected. We illustrate the benefits of the proposed models with a simulation study and two case studies.
