我国农业产业化组织中契约制稳定性的博弈研究

农业产业化组织中契约制是一种具有不稳定性特征的组织形式,我国契约制中的龙头企业和农户处于不完全信息状态,由此而引起的双方短期行为,导致了屡屡出现违约现象。以“信誉机制”这种市场力量和“专用性投资”方式增加企业和农户彼此的信任与依赖,使他们的利益趋于一致,可实现增强契约稳定性、降低风险的目的。     

宋代文化政策宽明原因新探

宋代文化政策之宽明,作为一种历史现象,是由多种历史条件交合作用而形成的。首先是宋以前中国多元文化格局及宽明文化政策历史传承的结果;其次是宋代抑武重文集权措施之偏倚所造成;另外,“皇帝与士大夫共治天下”的政治格局,使士大夫思想自由、精神独立,对皇权进行约束,是宽明文化政策之保障。     

‘Allowed into a Man's World’ Meanings of Work–Life Balance: Perspectives of Women Civil Engineers as ‘Minority’ Workers in Construction

This article discusses how women working as civil engineers within the UK construction industry perceive work–life balance and considers strategies they use to achieve this. The findings are presented of a qualitative research project that explored the experiences of women in this role, focusing on the subcultural context of a profession that is dominated by the values of presenteeism and infinite availability. A feminist post‐structuralist framework is used to analyse how women negotiate their personal and professional time and the extent to which their other roles as carers and nurturers unsettle male work practices in this highly gendered profession. There are gradually increasing numbers of women in professional construction roles and their success appears to depend on being able to fit in to the dominant masculine culture of long working hours and the male pub gathering. Despite an increased presence, women's minority status in construction continues to challenge their professional identity and this is central to the conflict many face between the dual roles of corporate worker and private non‐work person.     

Perfect simulation for correlated Poisson random variables conditioned to be positive

In this paper we present a perfect simulation method for obtaining perfect samples from collections of correlated Poisson random variables conditioned to be positive. We show how to use this method to produce a perfect sample from a Boolean model conditioned to cover a set of points: in W.S. Kendall and E. Thönnes (Pattern Recognition 32(9): 1569–1586, 1999), this special case was treated in a more complicated way. The method is applied to several simple examples where exact calculations can be made, so as to check correctness of the program using ²-tests, and some small-scale experiments are carried out to explore the behaviour of the conditioned Boolean model.

Engineering Identity: Gender and Professional Identity Negotiation among Women Engineers

This article considers how women in a gendered profession, engineering, construct their professional identity in response to workplace interpersonal interactions that marginalize it. Using data from interviews with women engineers, it also explores how these interactions influence the engineers' sense of self and belonging in engineering. The interpersonal interactions place professional identity on the periphery and can overly validate gender identity. I discuss two types of identity construction strategies employed by the participants in response to these marginalizing interactions: impression management tactics and coping strategies. Although the data demonstrate that participants may be left feeling devalued or ambivalent towards their identity or fit in engineering, some interactions are more validating and offer a sense of belonging. This article also reflects on how the engineers' actions may, in fact, represent forces for change in the gendered culture of engineering.     

刘长卿集版本源流试说

唐代刘长卿因诗而得名,后世对他的诗集给予了极大的关注。本文在学习和借鉴前辈学者研究成果的基础上,通过认真研习和比较查证,详细地梳理出刘集的版本源流,以期呈现一个更加明晰的面貌。相信这也将对刘长卿的诗歌研究有所支持。同时,针对版本命名和承续关系提出一些不甚成熟的想法,就教于前辈方家。
