微文化背景下大学生思想政治教育研究

随着微文化的不断发展,全国各地大学生的沟通交流方式越来越趋向于网络流行化。就现实角度而言,微文化动摇了高校思想政治教育的权威性,对传统思政教育的模式以及内容皆产生了一定的冲击,增加了高校思政教育者的难度,弱化了学生对主流价值观的认同。文中首先就微文化进行简要概述,其次针对微文化背景下的大学生思政教育提出有效的策略。

Embracing the Opportunities Ahead: An Analysis of Communication Position Announcements for 2013–2014

Knowing what the Communication job market is can be helpful and informative when planning how to build a program of study or research. On the other side, those who are looking for a job or are preparing for future job hunting also need knowledge about the current job market to help make decisions and predictions. To facilitate these processes, this article surveys the entirety of job postings posted on NCA’s CRTNET service and Spectra publication over the course of 2013 and 2014. The analyses provide an in-depth look at what kind of positions are being offered, which have tenure-track options, what degrees are required, if and what research methodological experience is needed, what kind of institution is offering the position, whether grant and/or teaching experience is desired, and what kinds of topical specializations are sought after.

中国神话的历史化及其对中国叙事文的影响

中国古代曾出现的将神话传说本身改造成历史的神话历史化运动 ,使中国古代的体系神话不同于古希腊的体系神话 ,并且由于神话历史化内容不仅是将神话传说的内容改造成历史甚至是现实内容 ,而且还包含着将现实的人物神化、将现实内容非现实化倾向 ,致使中国古代的叙事文 ,无论是历史叙事文、志怪类叙事文 ,还是文学叙事文都受其影响     

In vitro remineralization of hybrid layers using biomimetic analogs

Resin-dentin bond degradation is a major cause of restoration failures. The major aim of the current study was to evaluate the impact of a remineralization medium on collagen matrices of hybrid layers of three different adhesive resins using nanotechnology methods. Coronal dentin surfaces were prepared from freshly extracted premolars and bonded to composite resin using three adhesive resins (FluoroBond II, Xeno-III-Bond, and iBond). From each tooth, two central slabs were selected for the study. The slabs used as controls were immersed in a simulated body fluid (SBF). The experimental slabs were immersed in a Portland cement-based remineralization medium that contained two biomimetic analogs (biomineralization medium (BRM)). Eight slabs per group were retrieved after 1, 2, 3, and 4 months, respectively and immersed in Rhodamine B for 24 h. Confocal laser scanning microscopy was used to evaluate the permeability of hybrid layers to Rhodamine B. Data were analyzed by analysis of variance (ANOVA) and Tukey’s honest significant difference (HSD) tests. After four months, all BRM specimens exhibited a significantly smaller fluorescent area than SBF specimens, indicating a remineralization of the hybrid layer (P≤0.05). A clinically applicable biomimetic remineralization delivery system could potentially slow down bond degradation.     

多元文化背景下学校德育的文化应答

当前,文化的多元化越来越被人们所认同。在这种文化多元化、价值取向多元化的背景下,学校德育陷入困境。选择文化学的视角,基于多元文化发展的要求理性地反思我国学校德育的现状,根据社会发展及人自身发展的要求做出应答,有助于从新的视角为提高德育实效做出努力。
