论高等教育大众化阶段的学风建设

在当前高等教育大众化阶段,高等教育学风建设存在着缺乏学习的主动性、厌学现象严重、学习动力不足、学习方法简单、素质有待提高等问题。对此,提升学生学习兴趣应采取以下对策:提高大学生的适应能力是解决低年级问题的着眼点;提高学生的学习兴趣是解决高年级问题的切入点;增强创新意识,提高高年级学生的实践能力。     

知识生成转化的三层嵌切球与Ba/巴交互作用模型建构

通过简要回顾知识管理理论的产生与发展,剖析了知识管理研究存在的问题,指出其研究重点应该转向深层次的知识生成转化。在此基础上,建构了三层嵌切球与Ba/巴交互作用模型,并基于该模型从一个全新视角研究了经典的野中—竹内范例。     

我国网络社会构建公共领域的困境分析

公共领域是一个处于私人领域和国家之间的社会交往及理性批判空间,其核心是公共利益和公共意志。网络的发展无疑给公共领域的构建带来新的机遇,但也助长了消费主义的泛滥,带来了严格的信息过滤以及社会群体极端化、分裂化的倾向,使公共领域的构建面临新的困境。而这一困境的解决有赖于自由表达体制的建立和政治现代化的进程。     

Theoretical solution of a spherically isotrophic hollow sphere for dynamic thermoelastic problems

The separation of variables method was successfully, used to resolve the spherically symmetric dynamic thermoelastic problem for a spherically isotropic elastic hollow sphere. Use of the integral transform can be avoided by means of this method, which is also appropriate for an arbitrary thickness hollow sphere subjected to arbitrary thermal and mechanical loads. Numerical results are presented to show the dynamic stress responses in the uniformly heated hollow spheres.

索伯列夫空间W1,p(D)中的非线性椭圆组的非线性Riemann边值问题

The nonlinear Riemann problems were converted into nonlinear singular integral equations and the existence of the solution for the problem was proved by means of contract principle.     

“A man's mouth is his castle”: The midcentury fluoridation controversy and the visceral public

This essay forwards a theory of “visceral publics” through a case study of a bitter public health controversy in a small midcentury New England town. Proponents of fluoridation claimed that it yielded significant positive health outcomes, while opponents charged that the measure was politically suspect and physically dangerous. In this essay, I analyze the controversy as it took shape in letters to the editor and argue that the root of opposition to fluoridation was not in political ideology, as scholars have often claimed, but in a perceived threat to the body's boundaries, which created intense feelings. Although visceral publics are most clearly observable in controversies over the boundaries of the human body, the essay concludes by showing how the concept may be applied to controversies over the boundaries of the national body as well.
