浅析空间的物权价值

我国颁布的《物权法》(草案)没有关于空间权的规定,民商法学界关于空间权的研究也不多见。随着现代工业尤其是现代土木建筑技术的发展,土地的立体利用越来越普遍,有关空间利用纠纷也相应增加,对空间权进行物权法方面的研究也就成为法学工作者的一项重要任务。作者试图通过对空间权的法理、含义、性质、体系等方面的研究,以期达到抛砖引玉之效果。

“直播自习室”：新媒介技术下的空间组合与超人际互动

移动互联网的发展使媒介越来越深地介入我们的日常交往与生活,也进一步拓展和重组了人类生活的空间图景。文章采用参与观察和深度访谈的方法,探究“直播自习室”这一新型空间实践活动。研究发现,参与者加入“直播自习室”是为了获取陪伴与督促的学习氛围,将此作为个人学习的“背景音乐”,并认为它是一个随时随地的互助空间。“直播自习室”通过实时连接不同位置的参与者,共同生成了一个线上公共学习空间。但这一空间不能被简单定义为新媒介技术对物理地点的复制或替代,更多是媒介空间与物理空间的组合,两者共同生成了新的社会空间。其中,社会交往与情感交流显现出超人际互动的特点,即身体分离但精神共在。     

论外层空间环境损害的国际责任

人类探索和利用外层空间的活动对地球和外空等环境造成了不利影响和多重损害,这已引起国际社会的广泛关注。空间环境损害必然引发国际责任,而加快完善有关空间环境损害的国际责任制度是当务之急。文章首先探讨现存空间法律规则对空间环境损害的规制,在分析当前空间环境主要污染源的基础上,总结现存法律框架中存在的主要问题,进而从责任制度的选择、归责原则、责任主体、求偿主体和责任方式等方面提出构建空间环境损害国际责任制度的建议。     

Third Space Activities and Change Processes: An Exploration of Ideas from Social and Psychodynamic Theories

Discussions pertaining to culture, power and/or identity frequently create tensions that are enacted by dyads and groups within schools, workplaces and communities. Although tensions can easily escalate into conflict or violence, we have observed that these tensions can serve as prompts that promote a change process. When individual perspectives are challenged, some participants are able to dissemble their views and consider other perspectives from which new understandings and views emerge. At times, when groups seem to be on the threshold of overt conflict, some participants engage in processes that examine the tension, explore new possibilities, and alter the view of one’s subjectivity. We suggest that these activities occur as momentary states in psychological spaces conceptualized as third spaces (Bhabha, The location of culture. London: Routledge, 1994). In this paper, we use concepts from psychodynamic and social theories to describe the conditions that coalesce to form states of mind (nepantla) (Anzaldúa, Borderlands/La Frontera: The new mestiza. San Francisco: Aunt Lute Books, 1999; Interviews Entrevistas. New York: Routledge, 2000) and the ability to engage in new relational possibilities (third space activities) with dyads and groups, outside of psychotherapy. The conditions include: critical consciousness, regulation, recognition, and responsibility. We then describe how such momentary experiences can subsequently result in an examination of one’s subjectivity, particularly as it pertains to issues regarding culture, power, and identity. Throughout the paper we provide four examples from various settings to illustrate these concepts and processes. Given the increasing racial/ethnic diversity of clients and clinical social workers in North America, this concept of third spaces holds particular relevance for contemporary clinical social work practice.

论《呼兰河传》的空间形式

探讨了萧红小说《呼兰河传》空间形式的创造对于传统小说诗学的突破。作为一部典型的空间形式小说,其主旨并非“追寻失去的时间”;分析了整一的空间情境、并置的空间结构、时间流动的中止是其空间形式建构的主要体现,并因此使得《呼兰河传》具有了现代品格,最终成为现代文学的经典之作。     

条件异方差动态Nelson-Siegel利率期限结构模型及其应用

动态Nelson-Siegel(DNS)利率期限结构模型将方差设定为常数,不能刻画收益率序列的条件异方差,降低了数据拟合和预测能力。本文用GARCH模型设定DNS模型观测方程条件异方差,基于适应状态空间模型用广义自回归得分(GAS)设定转移方程条件异方差矩阵,提出具有时变方差的GAS-DNS模型,将Rapisarda等的矩阵分解方法应用于协方差矩阵分解及再参数化保证协方差矩阵的正定性。采用中国银行间市场13种期限国债收益率数据进行实证分析,极大似然比检验表明,将DNS模型误差项方差矩阵时变化能够显著提高模型的对数似然值;以MAE、RMSE、MAPE和TIC为标准进行比较,显示GAS-DNS模型的收益率曲线样本内拟合效果和样本外预测能力均比DNS模型有显著提高。本文提出的GAS-DNS模型是对DNS模型的实质改进,鉴于利率期限结构模型和利率预测在实际应用中的重要性,本文的模型改进具有应用价值。     

What Future for Green Infrastructure Planning? Evaluating the Changing Environment for Green Infrastructure Planning Following the Revocation of Regional Planning Policy in England

ABSTRACT

The revocation of the regional tier of planning by the UK Coalition Government in 2010 removed the established framework of strategic planning in England. Using a case study of green infrastructure (GI), this paper examines whether revocation has negatively impacted the development of environmental, and specifically GI policies and practice. It questions if changing government policy narratives have hindered advocacy and subsequently the delivery of GI and the extent to which it has been able to position itself as a mainstream approach in planning. Using the development of the RSS in England, and the North-East and East of England sub-regional GI strategies (areas of significant policy development), as case studies, the paper presents an ex-ante evaluation prior to revocation of the evolution of GI policy at a regional scale, alongside an ex-post assessment (2011–2015) of its continued growth within sub-regional policies. The paper concludes that whilst RSSs provided a promotional forum, that revocation has not negatively impacted upon GI development, as its advocates have facilitated a supportive policy-implementation environment which has led to the development of more integrated approaches in planning praxis.
