Demand Systems Estimation With Microdata: A Censored Regression Approach

Demand systems estimation increasingly makes use of household-level microdata, mainly to measure the effects of demographic variables. Data based on these household-expenditure surveys present a major estimation problem. For any given household, many of the goods have zero consumption, implying a censored dependent variable. Techniques which do not take this censored dependent variable into account will yield biased results. We utilize a censored regression approach that is computationally simple, consistent, and asymptotically efficient. The results are then presented and compared with those obtained using an uncensored technique.

Anti-statism and Difference Feminism in International Social Movements

Feminist strategies that neglect or consistently deplore state action cannot accomplish what women need – because individuals need collectives such as states to solve collective action problems and to move toward more just social arrangements. Strategies that rely heavily on women's differences from men also cannot accomplish what women need – because women are like men in many ways relevant to individual and collective action. Despite these truths, social movements also need some strategies of action that work separately from and sometimes against the state. Moreover, strategies that accentuate the differences between oppressed and oppressing bring needed energy to a movement. The best overall strategy is, therefore, to realize that both states and difference theories are dangerous weapons, and proceed with caution.     

Young Women in the Australian Women’s Movement

This article explores and documents the role of young women in the contemporary Australian women’s movement. Through case studies of two very different groups of young women, working in submerged networks in the community and on university campuses, it aims to suggest the diversity of contemporary young feminist praxis. Further, it argues that the work that these young women are doing in discursively creating and maintaining a feminist political space is crucial to the future of the movement. Based in constructivist ‘new’ social movement theory this article suggests a way forward from the so-called ‘generational debates’ of the 1990s and argues that, through their own unique processes of collective identity, young women who are active in the Australian women’s movement are dealing with the conflicts that are essential to the movement’s survival.     

动产浮动抵押抑或特别动产集合抵押——对我国《物权法》第181、189及196条的理解

对我国《物权法》第181、189及196条所规范的制度的性质存在两种观点:动产浮动抵押及特别动产集合抵押。产生这两种观点的原因在于对浮动抵押制度界定的差异。浮动抵押制度的特征在于标的物的浮动性、抵押人处分抵押物的自由及可转化为固定抵押,依据这三个特征可以确定,我国《物权法》的181、189及196条所规范的制度为动产浮动抵押。创设特别动产集合抵押制度并不利于我国对这三个条款所规范内容的理解及适用。     

Framing Emerging Environmental Movement Tactics: Mobilizing Consensus,Demobilizing Conflict

This paper is a study of an emerging environmental decision-making model that attempts to move beyond traditionally adversarial approaches toward consensus building. Consensus-based decision making ostensibly allows activists equal power with industrialists and state actors in environmental policy-making. This research builds upon the growing literature on frame-analysis by demonstrating that there are instances when challengers actually engage in collaborative framing with their adversaries. This does not presume that activists reject oppositional framing altogether. In these cases, environmentalists actually draw on a mixture of confrontation and negotiation in this innovative form of collective action that positions them in contexts most environmentalists never experience—a place at the decision-making table with elites. This study reveals that environmentalists are becoming more sophisticated in their efforts to protect local communities and natural resources.     

民族文化心理的诗意传达——论南永前的图腾诗

中国当代朝鲜族诗人南永前的图腾诗以民族图腾诗这种文化原型为表现对象,传达的是整个民族的集体无意识心理。诗人借助图腾意象展现了民族文化心理的丰富内涵,使得历史与现实交汇、审美与人生同构,进而完成了对民族之魂的重铸。     

产品品种繁多类型企业投入产出表的处理思想与方法

对于生产装配性产品的机械企业，由于产品与原材料种类繁多，将造成企业投入产出表的规模庞大，致使投入产出表的编制、计算和使用产生诸多问题，甚至难以实现。为了控制表的规模，常采用将消耗量相近、生产工艺相近的产品合并的做法。但这种做法严重影响了投入产出表的精度和应用效果。因此，本文讨论了更为有效的解决这类问题的思想和方法。     

二元经济结构下的城乡居民收入消费水平的区域差异分析

我国的国民经济结构是一个典型的二元经济结构,东、中、西三大区域城乡差距依此递增,三大地带内部城乡差距呈现明显拉大趋势。这种现状产生的原因是多方面的,但农业和非农业部门劳动生产率水平的巨大差异和国家的农业投资政策是不容忽视的两个因素。推进二元经济结构演化,缩小城乡居民差距必须树立工农城乡协调发展的战略思想,加大对农业的投入,积极推进农村税费改革,加快城镇化步伐,实施农业产业化经营。     

我国农村集体土地所有权制度的完善--以"三农"问题为背景的分析

农村集体土地是维持农民生存的基本保障,而以家庭联产承包制为主的土地制度因分散经营而无法形成规模效益,对于共同富裕奔小康目标的实现,其功能是非常有限的.对农村集体的土地依照市场法则统一进行有效经营、形成规模效益是在农村实现小康目标的主要措施,这也是我国已经实现小康目标农村的普遍作法.但目前对农村集体土地依照市场规律进行统一经营尚存在法律制度上的障碍,主要是农村集体土地所有权主体不明以及缺乏核心权能(处分权),使集体土地所有权并非真正法律意义上的所有权.中央已经明确城乡统筹为解决"三农"问题的基本原则,与此相适应,我国农村土地法律制度应该与城市土地法律制度统一起来,这是完善农村集体土地所有权制度的基本途径.
