论民间伦理的功能

从文化功能的维度审视，民间伦理的社会功能主要表现在四个方面。其一，秩序功能。即在国家秩序尚未出现或在国家秩序难以达到的地方独立发挥其维持社会基本秩序的作用，或作为国家秩序与法律秩序的补充。其二，批判功能。即根据人性和生活实际的需要对国家倡导的正统教化伦理进行解释和修正，并在国家伦理丧失其合理性时，公然提出自己的道德主张。其三。宣泄功能。即通过民间伦理自由自在的言说方式，为民间社会积蓄的生命本能冲动找到一个合法发泄的渠道，避免郁积的生命能量的盲目发泄导致社会秩序的解体。其四，教化功能。即一方面通过民间伦理中那些直接来自于民间的价值观念和行为准则实现民间的自律，而另一方面则吸纳和接受来自于上层教化伦理的指令，协助其教化万民，美化风俗。     

School meal time and social learning in England

ABSTRACT

This paper presents an ethnographic account of the culture of school meal time at Peartree Academy, with a specific focus on notions of social learning. This qualitative study is focused on a collection of interviews, observations, field notes and analyses what happens when the school organises its canteen as a restaurant. The focus moves away from the traditional realms of nutrition and explicitly introduces the notion of social learning in its informal sense through which a conceptual framework of a skills model is applied. The paper argues how the school dining hall known as the restaurant can foster opportunities for a form of social competence which is not necessarily seen but can be experienced in the social reproduction of its actors. The findings highlight tensions of control within the environment, which are said to impinge upon these social learning opportunities from occurring.

批评话语分析中的隐喻现象研究——以腾讯QQ致用户信为例

批评话语分析（critical discourse analysis）作为语言学中新兴发展的学派,其主要目的是通过分析人们设计的符号来揭示语篇中含而不露的意识形态。隐喻（metaphor）作为认知语言学中的一个重要理论,近年来受到国内外学者的广泛关注。隐喻与社会性之间的关系在某种程度上把认知理论与批评话语分析结合起来,使构建认知批评话语分析框架成为可能。本文以分析CDA中的隐喻现象为基点,旨在探讨构建认知批评话语分析框架的可行性与优势;发掘大众语篇背后隐藏的意识形态并呼吁读者以批评的眼光阅读此类语篇。

The Art of Straying: Benjamin on Distraction and the Informal Education of the City

In this article, Tyson E. Lewis argues for an alternative form of educational attunement beyond attentiveness. Discourses and practices of schooling emphasize being attentive as a primary educational virtue. This emphasis casts distraction as either the negation of attention or its deterioration. In either case, distraction lacks educational use and, as such, must be overcome through the cultivation of attention. Yet this approach to the question of attention versus distraction misses how distraction contains within itself a different kind of educational potentiality, a different kind of educational attunement. In an attempt to carve out space and time for distraction, Lewis turns to the writings of Walter Benjamin who offers up a more complex view of distraction than is presently found in educational philosophy. In particular, Benjamin argues that cities are not only places of negative forms of distraction (as mere diversions), but also places for cultivating productive distraction in the form of an open and alert attunement to new ways of experiencing and perceiving the relationship between world and self. Cities, for Benjamin, become educational spaces that teach lessons in a distracted form of life, the culmination of which is the creativity expressed in what he refers to as “the art of straying.”
