中国古建筑群体空间构建的哲学语境

中国传统古建筑以单体组成群组,群体空间的平面图形特征表现为虚实相生,内外相融的特点,立体形态则如行云流水,无为而自然。按照＂天人合一＂、＂礼乐＂复合、＂仁义＂相携的哲学思想构建的古建筑群体空间,反映了以＂人＂为本、贵和尚中、自然无为的哲学意境。     

区域一体化背景下城市群产业生态效率及其时空跃迁特征

在区域一体化背景下，以江浙沪两省一市2009~2018年新材料产业面板数据为研究样本，基于DEA模型和空间自相关模型，分析该地区的城市群产业生态效率及其时空跃迁特征。研究结果表明，江苏省GDP总量与增速最快，新材料产业的集中程度较高且生态效率呈现快速上升趋势，生态效率以南部的苏州和无锡为中心向周围递减；浙江省生态效率缓慢上升，大致呈现由北向南递减的趋势；上海市则呈现下降趋势。江浙沪区域新材料产业整体呈现向苏南与浙北地区聚集的时空跃迁特征。行政支持、财政支持这两个驱动因素与新材料产业生态效率的灰色关联度呈现下降趋势，其余均呈现上升趋势。政府应结合城市群的生态效率发展特点与时空跃迁特征推进区域一体化建设，缩小城市之间的生态效率差异，实现区域协调发展。     

The clash of managerial and professional logics in public procurement: Implications for innovation in the health-care sector

This article addresses the enactment of public procurement and its influence on adoption and diffusion of innovation, using a case study of public procurement of a low-tech medical device innovation in Swedish healthcare. Based on interviews and documentation, the article illustrates the various perspectives of the different professions involved in the complex task of setting the requirement specification for the tender. The technology identities of the medical device (innovation) are constructed and negotiated by the actors: procurement administrators, health-care professionals and suppliers within the adoption space. Examining the enactment of the procurement process as part of the adoption space is a way to deepen our understanding of the social component within public procurement.     

企业家精神与南昌众创空间涌现--基于演化经济地理学视角

众创空间大量涌现是近年来新的空间经济景观。文章基于演化经济地理学,研究了企业家精神在南昌众创空间和创客项目形成过程中的作用机制。采用访谈与问卷方法,对6家众创空间进行了访谈,对创客项目发放了45份调查问卷。研究发现,对众创空间而言,创办者社会关系本地嵌入、房产资源的沉没投入是他们在南昌创办众创空间的重要原因;金融资本对企业家在南昌创办众创空间的影响由弱到强。对创客项目而言,尽管创业者的创业知识可能来自外地,但创业者社会关系本地嵌入是他们选择在南昌创业的重要原因;金融资本对创业者的影响也由弱到强。文章还研究了政策对众创空间涌现的影响。与通常默认"双创"政策对众创空间与创客项目涌现具有重要推动作用不同,文章认为政策对众创空间涌现的作用主要为信息杠杆与政策背书,而财政、货币激励主要对政策套利型众创空间涌现产生较强作用。     

Estimating the benefits of recreation-oriented management in state-owned commercial forests in Finland: A choice experiment

As forestlands provide a variety of environmental services, the management of forest resources is a matter of public concern. In the present case of state-owned commercial forests in Finland, legislation requires specific management practices to enhance recreational benefits free of charge to the public. This choice experiment considers Finnish people's valuation of the recreation-oriented management of state-owned commercial forests to evaluate whether the recreational benefits produced justify the related loss of profits from timber sales. We focus on three management attributes: scenic buffer zones along lakes and rivers, habitats for game birds, and the quality of scenery as reflected by the frequency of clear-cut areas along hiking trails. Marginal willingness-to-pay (WTP) effects for the attributes are estimated with random parameters logit models specified in the WTP space, while preference-space models are used to estimate in physical terms the attribute levels that maximize the benefits to the public. Despite regional differences in preferences, people in all parts of Finland valued the current recreation-oriented management of state-owned commercial forests considerably. Nationwide, the aggregate benefits of recreation-enhancing management clearly exceeded the estimated opportunity costs. The most preferred levels of management attributes were slightly above the current levels, suggesting an increase in the provision of recreational services when not considering the associated costs.     

中国生态经济发展的双层次博弈模型——以企业为中心的群体内外博弈分析

可持续发展的生态经济之路已成为我国经济转型的基本方向,然而"外部性"和信息不对称影响的存在给生态经济的推行带来了困难。通过构筑政府与企业的混合策略博弈模型,得出纳什均衡点,进而将均衡点引入企业间博弈,从而搭建起生态经济发展的双层次博弈模型。分析表明:政府加大对企业的补贴、提高投机的惩罚力度,有利于鼓励企业实施生态经济生产模式,而生态经济模式的额外成本却阻碍生态经济的推行。同时,通过企业群体内博弈分析表明:公众监督奖惩机制会对博弈参数影响生态经济的推行造成干扰,在公众监督对企业的综合奖励影响高于惩罚时,关键参数对推进生态经济的实施具有正面作用,反之则起负面作用。     

Spacing identity: Unfolding social and spatial-material entanglements of identity performance

In this paper, we analyze how architectural design, and the spatial and material changes this involves, contributes to the continuous shaping of identities in an organization. Based upon a case study of organizational and architectural change in a municipal administration at a time of major public sector reforms, we examine how design interventions were used to (re)form work and professional relationships. The paper examines how engagements with spatial arrangements and material artifacts affected people’s sense of both occupational and organizational identity. Taking a relational approach to sociomateriality, the paper contributes to the further theorizing of space in organization studies by proposing the concept of spacing identity to capture the fluidity of identity performance.     

GNSS空间覆盖性仿真分析

全球导航卫星系统（GNSS）对空间用户的应用价值在于GNSS信号对空间的覆盖性能，这不仅取决于星载信号发射器的信号辐射角范围，而且取决于用户自身的最小观测角。针对该问题，对GNSS空间覆盖性原理进行了分析，给出了判别依据，然后对GPS、GLONASS、GALILEO系统、北斗区域服务系统、“北斗”全球导航系统及“北斗”与其他GNSS组合共8种仿真方案，不同轨道高度用户的空间覆盖性进行了仿真。在实际应用中，可以根据仿真结果针对不同的应用任务选取不同的卫星星座或选取多星座互操作，以保证最大同时可见卫星数，从而更好地提升GNSS卫星星座的应用价值。     

Machinic Assemblages of Publicness

This article discusses the concept of publicness through the lens of Deleuze and Guattari’s machinic thinking. Centring on the case of the Bearpit, a roundabout and public space in the city of Bristol (UK), I examine recent shifts and transformations in public culture and narrate the ways in which relatively small interventions facilitate new connections and organize public assemblages. The article makes four main contributions. First, it develops an approach to the study of publicness that highlights the interactions of machinic assemblages of material and immaterial component parts. Second, it suggests that specific forms of publicness are mediated by bright objects which stitch together and organize ecologies of connected machines. Third, it outlines publicness as a dynamic, plastic social form. Finally, it argues that the struggles for a compassionate public culture in the Bearpit are not necessarily set on a fixed trajectory toward co‐optation or a return to revanchism, but rather are part of an incessant process of unfolding and becoming public where the concerns and contestations of publicness are made visible.
