THEIR SPACE: SECURITY AND SERVICE WORKERS IN A BRAZILIAN GATED COMMUNITY*

ABSTRACT. This study examines the role of service workers in creating a secure landscape in a zone of gated communities near Belo Horizonte, Brazil. Most research on gated communities emphasizes their segregation and formal security apparatuses. In fact, gated communities interact with surrounding rural settlements because they draw their service employees from them. Security emerges from informal relationships of trust that property owners establish with service workers. Gardeners, especially, enable homeowners to project their property investment to others through landscaping. Equally of importance, a manicured garden conveys the message that a home is receiving daily attention—and is secure—even if the owner is not present. The study probes this interdependence from the point of view of gardeners in the context of one gated community in an area south of Belo Horizonte and the attempts by members of its homeowners association to minimize the sense of fear they associate with the Brazilian city.     

AVIAN NESTING HABITS AND VEGETATION STRUCTURE

Discriminant analysis is used to identify relationships between vegetation structure and nesting behavior in 78 breeding bird communities in North America. Results indicated that bird communities associated with structurally similar vegetation exhibited similar arrays of nesting habits despite their geographical separation. Tree-cavity, intermediate-cup, and high-cup nesters dominated forests and woodlands; ground-cup and ground-scrape nesters dominated grasslands; and low-cup nesters dominated desert, scrub, and some woodland sites. These functional relationships are distinct from previously reported continental scale relationships between avian feeding habits and gross vegetation structure. Links between nesting behavior and vegetation structure provide us, as geographers, with a means for placing birds into a physical landscape perspective.

Gated communities in England: historical perspectives and current developments

It is important to analyse the growth of gated communities and the drivers for their supply and demand, within the context specific to each country’s history. This article uses findings from recent studies of gated communities in England, together with historical material, to explore their typology. It considers the changing social, economic and political conditions which may lead to the emergence of defended collective housing, together with the history of property relations and the concept of public/private land within the English context.     

Pow Choon-Piew's contributions to urban China studies

This commentary serves as a tribute to the late Pow, a remarkable scholar in urban geography and urban studies, summarizing his contributions to urban China studies. It aims to showcase the way in which Pow's work manoeuvred adroitly with an implicit comparative gesture—building a bridge between situated Chinese cases and wider theoretical debates in urban studies in order to enrich both domains. The essay then summarizes Pow's work in the field of urban China studies by focusing on two most emblematic topics that he delved into in great depth, i.e., gated communities and eco-city developments. The final section develops a brief quantitative analysis of the impact that Pow's work has generated. Using the software packages CiteSpace and HistCite, I unpack how his publications are cited and used by scholars, journals, and different areas of research.     

青年知识移民就业城市选择及其影响因素

随着城市知识经济转型,各个城市越来越重视对知识人才包括青年知识人才的吸引。以广州市高校大学生为例,采用定性和定量相结合的方法,从城市与个人的双重视角探讨高校青年知识移民就业城市选择的特点及其影响因素。研究发现：1）青年知识移民总体上倾向于选择其本科或研究生就读地所在的城市和比其户籍地与就读地更高等级的城市（如一线、新一线城市）就业,这反映了他们向上空间流动和社会流动的意愿与动机;2）他们的就业流动是城市因素和个人因素共同作用的结果,其影响因素主要包括城市经济、城市环境、城市政策与城市文化,以及青年知识移民来源地的户籍类型与户籍地的城市等级等;3）城市经济发展（工作机会）是吸引高校青年知识移民的最重要因素,但与此同时,生存舒适度（生活机会）在青年知识移民的就业流动过程中所起的作用愈发重要,城市环境建设需要关注公共文化设施、社会舒适程度、交通便利程度、卫生服务设施以及城市自然环境和居住环境等方面的问题。个人因素方面,高校青年知识移民来源地的户籍类型与户籍地的城市等级对其就业流动决策具有显著的影响作用。细致探究青年知识移民就业流动规律及其影响因素是新时期理解和建构基于中国语境的知识型人才流动理论的需要,也是人才政策制定与知识人才实现自身价值的关键。     

时代、社会与真正的知识分子——兼论许倬云先生的思想及其影响

面对前所未有的大变局,知识分子需要深入理解时代、社会与自身的关系。知识分子受时空和社会环境所制约和影响,但也存在思想超越时空和社会的可能性。以历史学家许倬云先生为例,通过现身说法,深入阐发和延伸探讨了他所提出的知识分子的问题,指出知行合一与身体力行是知识分子的精神。真正的人文主义体现为对学术与人生的饱满热情和敏锐洞察,既有价值理念也有思想深度,并将知识内化为行动传递下去。只有发现并立足于真实的人性和生活,知识分子才有超越的可能性。认清世界和自我的限度,竭尽所能地突破或超越这种限度,其实就是在面向未来和创造未来。     

北京低收入社区居民社会公平感知的 影响因素研究：基于空间公平视角

随着北京市“国际一流的和谐宜居之都”建设步伐的加快,城市低收入社区居民的社会公平满意度越来越受到重视,居民的居住环境空间公平将受到更多的关注。本研究结合地理学和社会学对居住环境空间公平相关理论,基于2017年北京典型低收入社区的调研数据,实证分析了居住环境主客观条件对低收入社区居民社会公平感知的影响。结果发现：不同类型社区的居民社会公平感知水平差异明显;服务设施、就业可达性和建成环境对个体社会公平满意度也均有不同程度的影响,居住环境满意度对低收入社区社会公平感知的影响中存在调节效应,同时居民社会公平满意度因居民社会经济属性而异。     

Co-occurrence patterns of above-ground and below-ground mite communities in farmland of Sanjiang Plain,Northeast China

One of the fundamental questions in community ecology is whether communities are random or formed by deterministic mechanisms. Although many efforts have been made to verify non-randomness in community structure, little is known with regard to co-occurrence patterns in above-ground and below-ground communities. In this paper, we used a null model to test non-randomness in the structure of the above-ground and below-ground mite communities in farmland of the Sanjiang Plain, Northeast China. Then, we used four tests for non-randomness to recognize species pairs that would be demonstrated as significantly aggregated or segregated co-occurrences of the above-ground and below-ground mite communities. The pattern of the above-ground mite commu- nity was significantly non-random in October, suggesting species segregation and hence interspecific competition. Additionally, species co-occurrence patterns did not differ from randomness in the above-ground mite community in August or in below-ground mite com- munities in August and October. Only one significant species pair was detected in the above-ground mite community in August, while no significant species pairs were recognized in the above-ground mite community in October or in the below-ground mite communities in August and October. The results indicate that non-randomness and significant species pairs may not be the general rule in the above-ground and below-ground mite communities in farmland of the Sanjiang Plain at the fine scale.     

Experiences of host communities with carbon market projects: towards multi-level climate justice

The literature on equity and justice in climate change mitigation has largely focused on North–South relations and equity between states. However, some initiatives (e.g. the Clean Development Mechanism (CDM), the Reducing Emissions from Deforestation and Forest Degradation programme (REDD), and voluntary carbon markets (VCMs)) are already establishing multi-level governance structures that involve communities from developing countries in global mitigation efforts. This poses new equity and justice dilemmas: how the burdens and benefits of mitigation are shared across various levels and how host communities are positioned in multi-level governance structures. A review of the existing literature is used to distill a framework for distinguishing between four axes of climate justice from the perspective of communities. Empirical evidence from African and Asian carbon market projects is used to assess the distributive and procedural justice implications for host communities. The evidence suggests that host communities often benefit little from carbon market projects and find it difficult to protect their interests. Capacity building, attention to local power relations, supervision of business practices, promotion of projects with primarily development aims and an active involvement of non-state actors as bridges between local communities and the national/international levels could potentially contribute towards addressing some of the key justice concerns.Policy relevance International negotiations on the institutional frameworks that are envisaged to govern carbon markets are proceeding at a rather slow pace. As a consequence, host countries and private-sector actors are making their own arrangements to safeguard the interests of local communities. While several standards have emerged to guide carbon market activity on the ground, distributive as well as procedural justice concerns nevertheless remain salient. Four empirical case studies across Asia and Africa show that within the multi-scale and multi-actor carbon market governance, local-level actors often lack sufficient agency to advance their claims and protect their interests. This evidence suggests that ameliorating policy reforms are needed to enhance the positioning of local communities. Doing so is important to ensure future acceptability of carbon market activity in potential host communities as well as for ensuring their broader legitimacy.
