发电成本垂直差异电力市场概率发电——基于大用户电量偏好视角

针对碳减排后普遍存在的发电成本垂直差异电力市场及其显著的大用户电量偏好差异,本文提出概率性电量供给以及与之对应的概率发电,并利用价格杠杆调控发电商低碳发电尤其高发电成本发电机会与供给效能不足.先后构建发电成本内、外生选择下的概率发电模型,求解发电商的电量供给均衡并分析概率发电策略的最优性.最后,将发电成本内生选择模型拓展到分解市场需求不确定性的概率发电模型.研究发现:相比基准发电,概率发电可以作为一种有利可图的发电容量过剩的解决方法,即使在发电成本内生选择时也是可行的;当发电商采用“强”成本差异的发电策略时,引入折中的概率发电会让产品线上成本水平相互更接近,且大用户的消费者剩余得到提高;与此相反,在市场中实施“弱”成本差异发电,发电商利用概率发电则增大成本分离并降低大用户的消费者剩余;在不确定性市场需求下,当偏好低发电成本电量的大用户对单位发电成本的估价相对于偏好高发电成本电量的大用户对单位发电成本的估价足够高时,概率发电可以以一种管理不利需求状况工具的身份出现.     

冲突与达鹄:公众参与视野下的长三角公共冲突事件分析——基于2010-2012年的案例

以2010-2012年发生在长三角的公共冲突事件为例,运用案例比较分析方法,对公众参与和公共冲突事件的关系进行分析。研究发现:长三角地区的公共冲突事件起因多与公众的经济权益受损相关,作为中间变量,社会公众往往以非制度化参与致使冲突升级为"威胁","迫使"上级政府出面协调各方利益并终止公共冲突。分析表明:赋予并落实公众公共事务参与权利,有助于解决中国当前面临的公共冲突问题。     

农民工城市融入的组织化实践

不同于既有农民工城市融入研究中的宏观制度主义视角,也区别于单一组织微观实践路径的研究取向,文章基于粤南沙镇的实地调研经验,总结提炼出“半正式组织”这一新型实践类型,有助于弥合既有研究中的宏观与微观鸿沟。“半正式组织”是对现代组织“正式与非正式”二元对立框架的尝试性超越,在组织结构、成员关系、资源链接方式等方面均呈现新特征,其形成机制可概括为党建引领、组织挂靠与领袖吸纳。“半正式组织”的实践功效表现为助推农民工在流入地提升经济机会,增强政治参与,链接公共服务,扩展群体社会交往,因而成为现阶段有限制度供给和市民化成本分摊机制不均衡情境下,实现农民工城市融入的新路径。     

公民参与:我国政府决策民主化的应有之义

现代民主理论的产生,为公民参与政府决策奠定了理论基础.就目前我国的实际情况而言,公民在意见表达、参与水平、及参与的影响力等方面存在很多问题,应从公民参与的制度层面、政治文化层面、组织规模层面提高公民参与政府决策的水平,特别是要保持公民参与和政府承受力之间的平衡.     

Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ ² and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being. Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically. In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement. Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

Labor force participation and juvenile delinquency in Taiwan: a time series analysis

This study examines the null hypothesis of Granger no-causality between labor force participation (LFP) and juvenile delinquency in Taiwan. In order to explore this issue more thoroughly, this study adopts the approach proposed by Toda and Yamamoto (1995, Journal of Econometrics, 66(1–2), 225–250). It uses official time-series data provided by the Government of Taiwan. After estimating both a four- and five-variable VAR system, one that substitutes both male and female LFP rates for the aggregate LFP rate, the primary findings of this study reveal the following: The higher the past juvenile crime rate, the lower the future aggregate and female LFP rate will be. In addition, the higher the past male LFP rate, the higher the future juvenile crime rate will be. These findings are quite robust in terms of different lag-length structures.

上海社工职业化模式问题与展望

上海社会经济的发展需要职业化和专业化的社会工作。20世纪90年代中期以来,上海一直在稳步推进社会工作职业化。以授权为特征的职业化的主要内容包括:政府购买服务,民间组织经营,行业自律与管理,注册社工提供专业化服务。在职业化的过程中,上海社会工作在性质定位、需求定位、非政府参与和制度框架等方面还存在一些问题。面向新世纪,上海社会工作职业化需要全面拓展,走近百姓,广泛参与,规范运作。     

A new tool for urban governance or just rhetoric? The case of participatory budgeting in Taipei City

Increasing interest in participatory budgeting has been observed in local governments around the world. This paper stresses direct citizen participation in the budgeting process leads to good governance, deepens democracy and improves social justice, while also highlighting some challenges in its efficiency and effectiveness. Unlike participatory budgeting, the Sub-borough Chiefs Forum is a community-based representative democratic mechanism; it could be regarded as a form of participatory budgeting in a broad sense. If so, then did the Taipei programme simply duplicate the goals of the Forum or lead to a better governance by making up for the inadequacies of the Chiefs Forum? To find out whether the Taipei participatory budgeting programme made a difference, we carried out qualitative and quantitative comparisons of projects passed under the participatory budgeting process and at the Forum. We also interviewed several participatory budgeting participants and sub-borough chiefs. The findings suggested that participatory budgeting and the Forum generated different proposals and budget requests, and the Taipei programme supplemented the shortcomings of the Forum and therefore led to deeper civic engagement and better urban governance.     

Age limits for participation in child protection court proceedings in Sweden

According to the UN Convention on the Rights of the Child and Swedish legislation, children have the right to participate in child protection proceedings. The aim of this paper is to describe and analyse the notion of age and maturity in child protection proceedings in order to elucidate how these aspects could influence children's rights to participate. We focus on the view of three groups of actors involved in child protection proceedings in Sweden—social workers, lawyers, and laypersons in social welfare boards and administrative courts—and on how children's age and maturity should be taken into consideration in decisions on their participation in court. The analysis is based on survey data. The study found that social workers, laypersons, and lawyers have different views on when children are old enough to have the right to litigate in court. Additionally, there is no consensus on how the maturity of the child can be assessed to inform the decision about participation. More discussion is needed about what competences a child needs to participate in court and to what extent this right should be limited by their age. Importantly, courts and decision‐making proceedings can be made more child friendly.     

Impact of older adults' mobility and social participation on life satisfaction in South Korea

South Korea has been experiencing rapid population aging. In an aging society, the need for healthy lives is greater. Two of the fundamental factors to enable independent and active life for the elderly are mobility and social participation. The purpose of this study was to examine the relationship between older adults’ mobility, social participation, and quality of life in South Korea. We used data from the 2017 National Survey of Older Koreans conducted by the Ministry of Health and Welfare and the Korea Institute for Health and Social Affairs and applied hierarchical regression. The major finding was that older adults’ mobility had a positive impact on their life satisfaction. After controlling for older adults’ mobility, social participation was positively associated with life satisfaction regardless of the place of residence. The findings of this study not only make a valuable contribution to further research on mobility and social participation but also provide new insight into improving older adults’ quality of life.
