近代城市空间改造的时空进程

近代城市人口的增长、城市职能的变化、市政机构的出现带来了城市空间的转变。２０世纪初，中国开始了大范围的城市基础设施改造与新建。其中最有代表性的是拆城、填濠、修筑环城马路的工程，此后全国大部分的城市改造都遵循了相似的模式。本文通过对近１２００座治所城市城墙变动信息的研究发现，２０世纪大规模的城市空间改造最初主要从东南沿海省份开始，３０年代末至４０年代的战争打破了这一过程，但随着新中国成立后城市建设的恢复，空间改造的进程继续向西部省份推进，总体上呈现由东向西，由中心向边缘发展的特点。     

城市更新背景下的文化旅游发展研究——以广州为例

文化旅游的兴起是当今旅游业发展的一大趋势。城市更新是城市发展的一种重要途径。随着文化消费时代的来临、文化经济的快速发展,文化旅游在城市更新发展中扮演着日益重要的角色。本文主要以广州为例,探讨了城市更新背景下文化旅游发展的意义、面临的问题和挑战以及进一步的思考。     

Contingent constellations: African urban complexity seen through the workings of a Ghanaian bus station

In this article, I explore the intricate relationship between regulation and contingency in processes of urban economic organisation by focusing on the workings of a central bus station in Accra, Ghana. After introducing the position of the station in Ghana’s urban economy and transport infrastructure, I set out its internal regulative arrangements in relation to larger socio-economic and political constellations the practices of the station workers are contingent upon. Next, I turn the analysis around and describe the ways in which people accommodate themselves within, exploit and thereby co-produce emergent contingencies. The focus on the station, I suggest, offers a window into the complex constituents of niche economic practices that prevail in many spheres of African cities and allows a nuanced reflection on the incongruous and undetermined dynamics of everyday urban ‘becomings.’     

Penny for Your Thoughts: Beggars and the Exercise of Morality in Daily Life1

Urban sociology has tended to study interactions between passersby and “street persons” with an emphasis on the ways street persons become bothersome, harassing, or dangerous. This article moves away from the focus on the ways interactions in public go awry and focuses on how individuals account for the mundane, everyday exchanges they have with strangers who seek their help. Based on interview data (N = 31) and qualitative analysis of data from an Internet survey (N = 110), this article suggests that the presence of beggars does not inherently symbolize urban decay to passersby and does not necessarily elicit anxiety, but instead provides a valuable texture of urban life. Further, the article argues that individuals, when justifying their responses to requests for help from needy persons (beggars) in urban spaces, use a variety of cultural strategies to maintain their perception of themselves as moral persons, both when they choose to help and when they refuse. Drawing from these findings, the article suggests that urban sociology and the sociology of risk would benefit from sensitizing their studies of public interactions to the diverse meanings individuals assign to them, rather than presupposing annoyance, anxiety, or fear as their predominant characteristic.     

Asset Accumulation: An Alternative Approach to Achieving the Millennium Development Goals

The United Nations Millennium Development Goals (MDGs) are unlikely to be achieved by 2015, owing to conceptual flaws in their design as well as the structural and political constraints faced during implementation at the country level. While criticism of the MDGs is widespread, innovative ideas on addressing these operational challenges are still scanty. By reviewing a number of experiences, including those of the Foundation for the Promotion of Local Development (PRODEL) in Nicaragua and the Ministry of Cities in Brazil, this article highlights the importance of incorporating an asset‐accumulation perspective into MDG‐related policies and programmes as a way of generating an enabling environment that opens up new opportunities for poverty reduction in the cities of low‐ and middle‐low‐income countries.     

建构一个新的城乡一体化分析框架：机会平等视角

对城乡一体化的现有研究或采用经济学视角,或采用制度学视角,而很少采用机会平等视角。研究认为:不论是经济资源配置还是制度和政策制定,都要视对城乡机会平等的影响如何,来判断其是否促进城乡一体化进程。机会平等是城乡一体化的本质属性。当然,机会是复杂、多样的,可以划分为基本生存机会、中层机会和高层机会,与此同时,平等也可以划分为形式平等和实质平等。在推进不同类型机会平等上,城乡一体化表现出不同的进度。该分析框架可以更好地分析我国城乡一体化进程(包括地区城乡一体化进程)。     

基于模糊理论的城市快速路交通状态检测算法

通过分析流量、速度、占有率与城市快速路交通状态的关系,提出了一种基于模糊理论的城市快速路交通状态检测算法。通过在深圳市某快速路上的实际验证表明,该算法在能保证一定的检测率情况下,具有较低的误报率和较少的检测时间,表明此方法在实际应用中是切实可行的。     

“春秋笔法”与唐代小说叙事谋略探微

唐代尚史之风弥漫于文坛,造就了小说家特定的知识结构,从而赋予他们以突出的"史才";而许多唐代小说又多与当时的政治现实密切相联,为能自由地抒情言志、寄寓褒贬,于是源于历史叙事传统的"春秋笔法"便成为唐代小说家重要的叙事谋略."春秋笔法"的内涵为:作者不作论断,而是将自己的主观褒贬暗寓于客观冷静的叙事之中;叙事隐晦深曲,讲究匣剑帏灯、旁敲侧击.此二法在唐代小说中得到了充分显示.     

关于建立城乡统一的社会保障体系的浅见

建立城乡统一的社会保障体系不仅是学术界争论的焦点，也是实践部门讨论的热点。各种主张众说纷纭。然而，建立统一的社会保障体系不能凭空设想，应立足于实际，坚持具体问题具体分析。当务之急是根据农村的情况，分地方、分人群、分层次建立安全有效的农村社会保障体系。     

Black men teaching: toward a theory of social isolation in organizations

ABSTRACT

While there continues to be increasing research about Black male teachers’ school-based experiences, there is less empirical evidence on the variation in these experiences for this subgroup. Drawing on Kanter’s Theory of Numbers and Group Composition, the researcher used the qualitative method to compare the perceptions of Black male teachers in schools that employ just one Black male teacher versus schools with larger numbers of Black male teachers. A theory of social isolation in organizations is proposed to explain differences in the variation of school-based experiences for Black male teachers. When compared to Black men in schools with larger percentages of Black male teachers on the faculty, those Black men who were the only Black male teachers on their faculty were more likely to describe feeling socially isolated and disconnected from their colleagues.
