社会学视野中的“三农”问题(笔谈)

"三农"问题一直横亘在我们心中,拂之而不能去。用社会学视野观察之,是想让具有乡土情结的人"倾听它的声响"。本期论坛主要讨论实现城乡协调发展必须进行体制改革、如何突破城乡二元结构、尊重和依靠农民跳出历史周期律、"组合竞选"谁与之争峰以及影响农民职业流动的因素。陆学艺教授认为,实现城乡协调发展必须打破"城乡分治、一国两策"的体制格局。郭书田研究员认为,突破二元经济社会结构必须在十四个方面予以改革;石山老先生认为,应在总结历史经验的基础上,尊重和依靠农民跳出历史周期律;辛秋水研究员认为,在村民自治中创造的"组合竞选制"模式具有科学规范、公平合理、简便易行等优点,值得推广;同春芬博士则在全面评述国内外研究现状的基础上,分析了影响中国农民职业流动的制度因素、社会因素和人力资本因素。

Inequalities in school leavers’ labour market outcomes: do school subject choices matter?

Abstract

Despite a wide international literature on the effect of vocational and general education on school-to-work transition, relatively little is known about the role of having studied specific subjects in explaining inequalities in young people’s labour market outcomes. This paper aims to fill this gap by examining differences in employment chances of young people who left education early, either at the end of compulsory schooling or at the end of secondary school. Using data from the Scottish Longitudinal Study, a large-scale linkage study created using data from administrative and statistical sources, we found little gender differences but strong parental background differences in school leavers’ employment status and type of occupation entered. Social inequalities in labour market outcomes were only partly explained by curriculum choices. Moreover, after controlling for social origin and grades, only history and business for lower-secondary leavers and maths for upper-secondary leavers were associated with a reduction in the chances of being unemployed/inactive.     

Deconstructing the Patriarchy in Lawrence＇s Famous Work Sons and Lovers

19世纪的英国是父权制统治的时代,即男性拥有不容置疑的权利,而女性大都处于受压迫的地位。然而,依据德里达的解构主义理论,以20世纪英国著名的现代主义作家D．H．劳伦斯的《儿子与情人》为文本,在深入研究男主人公瓦尔特·莫瑞尔的生活历程和解构其男性权威的过程中,西方世界传统哲学的二元对立原则中所固有的一个单项统治另一单项的秩序、价值和逻辑的特征遭遇了彻底的挑战和颠覆。在缺失代替了存在而处于主导地位,本来的主次角色发生了转换之后,也就确立了父权制在压迫女性的同时,对男性自身也是一种束缚,甚至将他们推到了万劫不复的境地。     

Return journey: ‘snakes in the swamp’

In 1985 Falmer Press published my first book, a classroom ethnography entitled Initial Encounters in a Secondary School, which helped establish me as an academic. However, it has long concerned me that the decade-long Victoria Road Lower School Project (as it came to be called) contained two resounding ‘silences’:

• Silence 1 concerned the changing autobiographical, authorial ‘selves’ that lay behind it.

• Silence 2 concerned the unknown impact ‘Initial Encounters’ had upon Lower School and the subsequent careers of the teachers who had featured in it. To investigate this last year I managed to trace and interview some 60% of the staff (15 in total) who had featured in the original study.

‘Return Journey’ is best regarded as an experiment in ‘retrospective ethnography’, raising issues relating to both the autobiographical self and the ethics of ethnography, neither of which were accorded much significance in the late 1970s at the time of the initial research.
