The Internet and Demystifying Power Differentials

Abstract

Over the course of the past three years, a group of women residents of a forty-five-year-old public housing project have struggled with the housing authority to participate in the revitalization of that project. This article examines the emergence of a “critical consciousness” and action on the part of these women as a consequence of their going on-line on the Internet with their own home page. This article also looks at the historical and social context of their relationship with the local community and the housing authority as well as the women's ultimate challenge to the housing authority's sense of “exclusive” possession and use of information and data.     

‘Active Families’: Familization,Housing and Welfare across Generations in East Asia

Debates around welfare change have tended to concentrate on the balance between market and state provision. Although there is increasing reference to a mixed economy of welfare, this generally signifies a greater emphasis on a third sector of voluntary/community level provision. However, the family sphere has been, and still remains, an important and dynamic source of welfare provision across changing regimes and between generations. With this as background, the article addresses three particular questions. First, how has the role of families in the welfare mix changed over time? Second, how do family ‘strategies’ adapt to structural changes in order to maximize collective/individual benefits in certain areas and how do these strategies evolve over generations? Third, is such family engagement in welfare influenced by policy shifts appropriately conceptualized as ‘re‐familization’ or ‘de‐familization'? These issues are explored in the comparative socio‐economic and cultural contexts of China and Japan and draw on qualitative research with three generations of families in Shanghai and Tokyo.

“社会福利社会化”的陷阱——以广州老人院舍为例

踏入21世纪,我国已经迈入老龄化阶段.因此,如何面对及处理日益复杂和严重的老龄化问题势必成为我国构建和谐社会的重大问题之一.国家从1986年开始就一直推进"社会福利社会化"的进程,相关部门自1998年之后也相继出台了多条政策法规,希望能够鼓励社会各力量积极参与到老年人社会福利事业中去.笔者根据福利多元组合理论,对城镇老人院的供给主体进行分析,配以广州为例,从而试图揭示出"社会福利社会化"的政策一方面固然能够使更多经济有余力的老人有机会享受院舍服务;但另一方面却有可能排斥一群缺乏家庭供养、经济能力未必是最差但却无力支付"市场化"价格费用的老人进入老人院的机会.

论古典戏曲的“意境”——兼谈古代戏曲与古代小说及其诗歌的区别

以"写意"为其根本特征的古典戏曲,追求意境,是其创作的核心与宗旨。古典戏曲意境的创造是"情、景、事"三者的交融统一,并通过自然明白的表达和表演,在有限的境中表现无尽的意。它是抒情与叙事结合的综合艺术,提出"情中出景,景复含情"的创作原则。它是再现与表现结合的艺术,创造出"化实为虚,虚实相生"的美学原则,利用象征、夸张、虚拟等艺术方法写境,造境,创造形象,并追求"象外之意",营造出意犹未尽的戏曲意境。从而形成与西方写实戏剧不同的东方戏剧艺术的特色,跻身于世界三大古戏。     

Flexible Capacity Investments and Product Mix: Optimal Decisions and Value of Postponement Options

In this article, we study a firm's interdependent decisions in investing in flexible capacity, capacity allocation to individual products, and eventual production quantities and pricing in meeting uncertain demand. We propose a three‐stage sequential decision model to analyze the firm's decisions, with the firm being a value maximizer owned by risk‐averse investors. At the beginning of the time horizon, the firm sets the flexible capacity level using an aggregate demand forecast on the envelope of products its flexible resources can accommodate. The aggregate demand forecast evolves as a Geometric Brownian Motion process. The potential market share of each product is determined by the Multinomial Logit model. At a later time and before the end of the time horizon, the firm makes a capacity commitment decision on the allocation of the flexible capacity to each product. Finally, at the end of the time horizon, the firm observes the demand and makes the production quantity and pricing decisions for end products. We obtain the optimal solutions at each decision stage and investigate their optimal properties. Our numerical study investigates the value of the postponed capacity commitment option in supplying uncertain operation environments.     

关于农村土地承包关系“长久不变”的若干思考

比较了“永佃制”和《中共中央关于推进农村改革发展若干重大问题的决定》强调的“土地承包关系保持长久不变”的差异性,总结了永佃制对“长久不变”的启示。同时,基于农民视角,说明“长久不变”的必要性,认为“长久不变”的实质是土地承包权“长期化”。最后,从经济、人口、制度、文化心理等方面阐述了阻碍“长久不变”的因素,提出实现“长久不变”的几点措施：改革户籍制度、完善法律制度、建立农村社保体系、大力发展教育、完善配套措施等。     

Spillover effects of taxes on government debt: a spatial panel approach

It is claimed that tax policy is neither time- nor space-independent due to cross-border tax base mobility, which induces spillovers. Specifically, fiscal shocks in one country are supposed to have an impact on fiscal policies in other countries. Different types of taxes influence economies differently. This paper addresses the question of their impact on government debt. Within a framework of spatial econometric modeling, we evaluate the impact of capital, labor and consumption taxes on public debt in 34 European countries in 2002–2011, and find strong spatial spillovers. We show that a consumption tax and, to a lesser degree, a capital tax significantly affect the sovereign debt, and that the global relations play a leading role (i.e. dominate the local ones) in shaping fiscal policy.
