西学东渐与现代中国哲学

本文讨论了近代西学东渐对我国学界的影响,分析了当代中国大陆哲学的现状,提出了中国哲学遇到的问题及其发展方向。文章认为,近现代中国哲学不可避免地处于西方哲学的影响之中,中国哲学家现在面临的难题和任务,就是要在吸收西方哲学成果的同时,不搞全盘西化,而是从我们传统哲学中提炼出中国哲学特有的概念和问题,形成当代中国哲学的话语系统,建立中国特色的中国哲学。     

三燕时期辽西地区的农业发展

魏晋南北朝时期中原战乱频繁,河北山东等地的世家大族及众多流民纷纷迁徙到辽西,辽西地区的人口数量大为增加,中原地区的先进生产技术也随之传入。在十六国时期,前燕、后燕和北燕三个主要政权先后统治辽西,由于各政权对农业的重视和发展,加之优越的生态环境和地理位置,辽西农业在三燕时期有了较快发展。

三大战略促发展 全面振兴正当时

党的十六大特别是十七大以来,辽宁深入实施三大区域发展战略,尤其是辽宁沿海经济带开发开放上升为国家战略,沈阳经济区获批为国家新型工业化综合配套改革试验区,更极大地提升了辽宁的地位。为推动辽宁区域经济更加协调发展,2008年11月,辽宁省委、省政府又作出突破辽西北的战略部署,辽宁形成了完整的三大区域发展战略。     

合法性悖论:淘宝村民间团体的生存困境

大量淘宝网商在农村集聚,新兴"淘宝村"成为农村转型发展的模式之一,随之带来的是村内代表行业共同利益的民间团体不断涌现,这类新生团体的合法性建构及其面临的困境引人关注。一方面,自下而上发育的民间团体具有公众合法性能达致正常运转,却因无法获得体制合法性而陷入生存困境;另一方面,民间团体在获得体制合法性后却没有如预期般长期享受发展优势,反而动摇了先前的公众合法性,进入体制铁牢笼,同样也陷入生存困境,由此造成"合法性悖论"。公众合法性与体制合法性的冲突造成的"合法性悖论",反映了政府"体制控制"过强而民间团体自身对两类合法性的定位模糊,同时也体现了在市场转型日渐深入的背景下所凸显的"国家"与"社会"的矛盾。淘宝村社会组织的发展与"淘宝村"的未来前景息息相关,如何破解"合法性悖论",在当前背景下发挥民间团体的活力,其路径选择和发展模式也为社会治理提出了新的问题。     

Chinese youth performing identities and navigating belonging online

This paper examines the experiences of belonging of young Chinese internet users through an analysis of their online identity practices. Drawing on a qualitative research project about online citizenship practices of 31 young Chinese citizens from mainland China, I explore their experiences of belonging on two online platforms (Weibo and WeChat) and the identities formed and sustained through these experiences. The results show that young people experience different senses of belonging in different social media spaces. Their strategies in navigating these experiences are informed by (a) their perceptions of online spaces as private or public, and (b) using online identity performance as a supplement to or escape from identities in physical life. I argue that young Chinese internet users experience different senses of belonging by flexibly appropriating the affordances of social media platforms for communication and networking; these senses of belonging play a key role in forming and sustaining their identities, and are crucial for their wellbeing.

Dividend barrier and ruin problems for a risk model with delayed claims

In this paper, a compound Poisson risk model in the presence of a constant dividend barrier is considered. Two types of individual claims, main claims and by-claims, are defined, where every by-claim is induced by the main claim and and the time of delay for the claim is assumed to be random. A system of integro-differential equations with certain boundary conditions for the expected discounted penalty function is derived. We show that its solution can be expressed as the solution to the expected discounted penalty function in the same risk model with the absence of a barrier plus a linear combination of two linearly independent solutions to the associated homogeneous integro-differential equation. Using systems of integro-differential equations for the moment-generating function as well as for the arbitrary moments of the sum of discounted dividend payments until ruin, a matrix version of the dividends–penalty type relationship is derived. We also prove that ruin is certain under constant dividend barrier strategy. The closed form expressions are given when the claim amounts from both classes are exponentially distributed. Finally, a numerical example is presented to illustrate the solution procedure.
