Toward a sociology of global comparative placemaking

I call for a globally informed sociology of comparative placemaking that integrates historical and contemporary processes and includes the ephemeral, institutional, and personal. By placemaking, I am referring to the explicit or tacit cooperation among people to create, maintain, and give meaning to places in space through bodily occupation given differential resources and constraints. I review select place, space, and community-based literature about urban, Black, migrant, LGBTQ, and international populations to think about how we can build upon and integrate multiple theoretical, methodological, and epistemological insights to form an explicit placemaking research agenda. A US focus on neighborhoods contrasts with a comparative examination of global urban networks, social polarization, and transformation of the built environment in the interdisciplinary field of global urban studies (Ren, 2018). I argue for a placemaking research agenda that bridges insight from US Urban Sociology with Global Urban Studies to consider how various structures and actors constrain and facilitate place projects. With a globally reaching and comparatively informed sociology of placemaking, we can illuminate our multi-structured story of place and agency in context. We can answer questions about how and why we co-create and are simultaneously disciplined by the process of creation.     

城市综合体建设面临的一系列问题探讨--以南通市为例

随着房地产调控和城市化进程的加快，商业地产越来越受到开发商的青睐。城市综合体作为商业地产的典型代表以其多结构多层级的功能组合迅速提升区域价值而拥有了“城中之城”的美誉，在东部地区二三线城市大量涌现。但城市综合体带动城市发展的同时，也引发了一系列风险亟待关注。     

试论延吉城市旅游形象设计

在延吉城市旅游形象的诸要素中,民俗要素最为重要,因此,在对延吉城市旅游形象进行定位时,无论是从延吉城市形象的硬件上(如交通、餐饮),还是在城市旅游形象的软件上(如市民素质、民俗民风等方面),都要突出民俗特色,同时要用多种形式大力宣传。     

以城市为主导统筹城乡、区域和谐发展

长期以来,我国的区域经济实际上是农村主导型的发展模式。现在,这种发展模式已经走到了尽头,必然要向城市主导型区域经济发展模式的转变。这就要求区域经济发展应以城市为重点,推进城市化战略,统筹城乡发展,在此基础上构筑城市经济圈,统筹区域发展。城市经济圈的形成应打破行政界限,顺其自然地构建城市经济圈,因市制宜地探索城市经济圈的发展道路,逐步提升城市经济发展水平,以城市为主导统筹区域经济协调发展。     

Spatial variation in soil inorganic nitrogen across an arid urban ecosystem

We explored variations in inorganic soil nitrogen (N) concentrations across metropolitan Phoenix, Arizona, and the surrounding desert using a probability-based synoptic survey. Data were examined using spatial statistics on the entire region, as well as for the desert and urban sites separately. Concentrations of both NO₃-N and NH₄-N were markedly higher and more heterogeneous amongst urban compared to desert soils. Regional variation in soil NO₃-N concentration was best explained by latitude, land use history, population density, along with percent cover of impervious surfaces and lawn, whereas soil NH₄-N concentrations were related to only latitude and population density. Within the urban area, patterns in both soil NO₃-N and NH₄-N were best predicted by elevation, population density and type of irrigation in the surrounding neighborhood. Spatial autocorrelation of soil NO₃-N concentrations explained 49% of variation among desert sites but was absent between urban sites. We suggest that inorganic soil N concentrations are controlled by a number of ‘local’ or ‘neighborhood’ human-related drivers in the city, rather than factors related to an urban-rural gradient.

善治理论与中国地方治理

地方治理意味着地方政府从中央一体化的垂直结构下抽身,确立自身的独立地位与利益;同时,它也表征着民间社会力量的成长并逐步参与地方公共事务,成为地方治理中重要的参与性力量。在此意义上,善治理论提供了具有借鉴意义的理论框架和分析范式。但是,处于转型期的中国社会,在用善治理论观照中国地方治理时,其前提和基础条件的具备与否是受到质疑的,从而,这一分析框架的适用性也是有限的。

城市公众安全文化教育的方法与思路——兼议北京2008“安全奥运文化”普及问题

通过对安全文化发展演变历史的简单回眸,探讨了适用于城市安全减灾的安全文化教育的模式及方法,尤其从文化建设层面上研究了应用安全文化建设方法的特点。作为最现实的应用,还就2008年北京“安全奥运”的系统化建设提出了“安全奥运文化”普及教育的思路。     

中国古代城市文学研究的文学史意义

研究中国古代城市文学的文学史意义在于，从空间视角重新认识和研究古代文学，充分发掘和利用长期以来被忽略的城市文学资源。有助于建构起时空并置、更加完整和系统的中国古代文学史。此外，研究中国古代城市文学还可以为当代文学史研究提供一个广阔的历史视野与意蕴深厚的历史文本。
