论“道德自由人”—构建三网融合后的青年伦理生态

道德自由人意指道德精神在其实体中意识到自己被解放了。三网是道德自由人具有场域性、映像性、交互性、平等性特征的实体。道德自由人的出现是新世纪以来青年伦理意识的新动向。三网融合的趋势下,道德自由人的行动日益活跃,亟待冲出场域映像进入生活世界。道德自由人的出现给传统伦理带来了挑战,也为优化现有的伦理秩序提供了难得的机遇。以道德自由人为轴心,以三网为基地,构建青年伦理生态正是当前的急务。     

Empirical issues in lifetime poverty measurement

Recently there has been increased interest in developing methods for measuring poverty in a way that takes into account the lifetime experience of individuals. We analyze some specific proposals that take the so-called spells approach and consider how they differ in the manner in which they address issues of lifetime poverty, most notably the measurement of chronic poverty. Comparing these specific measures by applying them to a US panel data set, we provide important insights for further research in conceptualizing and measuring lifetime poverty.

网络青年文化的“自我空间”论

后现代的网络社会既给青年人寻找自我、建构身份搭建了广阔的新舞台,也为青年人提供了一个空间自由、文化自主的新天地——青年文化的"自我空间"。在这样一个以"自我"为中心和遵循"快乐至上"原则的空间里,青年人主动将自我符号化,充分运用网络媒介的自主权,通过创建微电影、微小说等微美学文本,把自己的内心世界投射到网络社会并最大限度地释放与表现、宣泄与满足。他们在"自我空间"里呈现自我、形塑自我的同时,也进行着青年亚文化的传播与实践。     

经济增长与日照减少:源自广东的实证研究

过去30年中国经济发展所取得的成绩举世瞩目,但生态环境污染日趋加剧亦成为不争的事实.作为中国现代化的缩影,1980-2010年,广东每增加1％的工业产值,日照时间减少0.3852小时.抽样调查的结果显示:目前广州、深圳等珠三角城市的日照时数已降至接近公众期望的临界值.遏制此种态势,转变经济发展模式固然重要,但更为重要的在于物欲的“零增长”.要做到这一点,日照时数应成为政府环保绩效评价的重要指标.
