广州市中产阶层日常活动的时空间特征

本文在对广州36个中产阶层聚居区881个中产阶层工作日与休息日活动日志问卷调查的基础上,运用时间地理学相关方法,探讨中产阶层日常活动的时间分配、空间分布和移动性特征。研究发现中产阶层工作日活动节奏清晰,休息日活动破碎化,工作日工作和休闲时间居多,休息日休闲和社交时间为主,不同属性的中产阶层工作日与休息日时间分配存在差异;此外,中产阶层"近家型"非工作空间特征明显,工作日与休息日活动空间分布集聚度最高的是核心商业区;以私家车和步行为主要的日常出行方式,"少次、多目的"的出行结构突出,日常活动空间移动能力较强。上述中产阶层的时空间特征与中低收入者存在明显不同。研究有助于揭示中产阶层的日常生活规律,为提高城市社会经济活力和完善城市精细化管理提供参考。     

基于生活空间与活动空间视角的郊区空间研究框架

郊区空间已成为城市空间的重要组成部分,其研究意义逐渐凸显,需要学者立足郊区,关注郊区空间及其与城市空间的关系。本文从行为主义地理学和时间地理学的理论和方法论出发,对行为空间、生活空间、活动空间的概念进行辨析,提出了基于空间范式下的生活空间研究和基于人范式下的活动空间研究两方面研究内容。立足于郊区空间,面向居民日常生活,构建基于时空间行为研究方法论的郊区空间研究框架,基于此框架对郊区生活空间、郊区活动空间以及郊区空间的动态性进行解读和分析,试图为空间-行为互动理论的构建提供研究基础,为基于行为视角的郊区研究提供研究框架,为更好的理解郊区空间、解决郊区中存在的问题提供有效途径。

CHINESE COMMERCIAL ACTIVITY IN THE TORONTO CMA: NEW DEVELOPMENT PATTERNS AND IMPACTS

This study, which examines recent development patterns of Chinese commercial activity in the Toronto CMA, yielded three major discoveries. First, new development in the past 15 years brought about not only a proliferation of ethnic Chinese businesses, but also considerable changes in business structure: the traditionally predominant restaurants and grocery stores declined substantially in proportion, but businesses that provide various types of consumer services expanded greatly. This indicates that the Chinese community has been steadily building a more complete and more self-sufficient ethnic economy. Second, while Toronto's three central-city Chinatowns have remained, most new developments occurred in the suburbs. Consequently, the spatial organization of Chinese commercial activities has become multinuclear, and their rapid spreading has begun to modify Toronto's traditional retail landscape. The third, and perhaps the most revolutionary, characteristic of the new development is the shift from unplanned retail strips to planned shopping centres, with the change of ownership from leasing of retail space to selling of store units. The new occupancy system, known as condominium retailing, is new to Canada and is associated only with ethnic Chinese retailing. In importance, condominium retailing has challenged both the conventional leasing system that has governed the development and operation of North American shopping centres over the past 40 years and long-established local planning systems. L'étude des nouvelles tendances du commerce chinois dans la région métropolitaine de recensement de Toronto a mis en évidence trois faits essentiels. Premièrement, le développement des 15 dernières années s'est traduit non seulement par une multiplication du nombre des commerces chinois, mais aussi par un bouleversement de la structure commerciale: les restaurants et les épiceries, jusqu'alors prédominants, ont vu leur importance relative diminuer au profit de magasins qui offrent des services aux consommateurs. Ceci reflète le fait que l'économie forgée par la communauté chinoise est de plus en plus autosuffisante. Deuxièmement, alors que les trois Chinatowns du centre de Toronto se sont maintenus, la plupart des nouveaux développements ont eu lieu en banlieue. Par conséquent, l'organisation spatiale des activités commerciales chinoises est devenue polynucléaire. Cette rapide propagation commence à modifier le paysage traditionnel du commerce de détail torontois. Troisièmement, et c'est peut-être là le fait le plus marquant, l'étude a révélé une révolution complète du mode d'organisation et de propriété des magasins. Aux groupements spontanés se sont substitués des centres commerciaux au sein desquels les commerçants ne sont plus locataires mais propriétaires de leur espace de vente. Ce système, que l'on pourrait baptiser le « condominium commercial » est un nouveau phénomène au Canada et ne concerne, pour l'instant, que les commerces chinois. Néanmoins, par son succès, le « condominium commercial » a remis en question les systèmes traditionnels de planification locale, aussi bien que le système classique des baux, qui a présidé au développement des centres commerciaux nord-américains au cours des 40 dernières années.     

城市建成环境如何影响老年人体力活动——模型构建与大连实证

针对建成环境与老年人体力活动关系研究中,较少定量刻画其与社会、心理要素交互作用的不足,本文构建了三者交互影响下的体力活动关系模型。研究发现：①老年人体力活动参与率整体不高,性别与家庭结构差异在活动表现形式上存在不同。②活动意向未能有效触发老年人体力活动,自我效能感是其重要参考因素;建成环境、社会资本对老年人体力活动的影响,由直接或间接通过自我效能感中介完成,心理健康作用则未显现。③家庭结构存在调节作用,建成环境单一要素对空巢老人体力活动的作用并不明显,但其对与子女共同居住老年人影响稳健。④社会资本是建成环境发挥空间干预老年人体力活动作用的重要前提;环境对公共健康的影响,更应采应取组合式干预策略。     

体育活动与"三个文明"建设的相关对应性

本文以“不同类型的活动与人的不同方面的发展存在着明显的相关对应性”理念为指导,论证了体育活动与社会主义“三个文明”建设的相关对应性。体育活动既是建设社会主义“三个文明”的重要构成元素,又是建设社会主义“三个文明”的重要途径和手段。所以,应全面细化全民健身计划,并制定相关政策,切实开展好全民、全程体育活动,不断扩大“体育人口”数量和提高“体育人口”质量。     

A CITY IN MOTION: TIME-SPACE ACTIVITY AND MOBILITY PATTERNS OF SUBURBAN INHABITANTS AND THE STRUCTURATION OF THE SPATIAL ORGANIZATION OF THE PRAGUE METROPOLITAN AREA

This contribution attempts to reveal the relations between new suburban areas and other parts of the Prague metropolitan area by investigating the time‐space activity and mobility patterns of the inhabitants of newly built suburban districts. The focus on some aspects of the everyday life of people in new suburbs helps us to identify the impact of suburbanization on the changing geography of the metropolitan region and to better understand how the spatial organization of the Prague metropolitan area is produced, reproduced and transformed. We use several interrelated concepts, which serve the theoretical foundation of our work, namely time geography, structuration theory and the post‐communist city. The empirical data utilized are primarily based on 262 diaries completed by eighty‐eight individuals from thirty‐eight households, accompanied by household questionnaires and interviews with the heads of households. The research confirmed the implicit, generally unspoken view that new suburbs in the Prague metropolitan region are heavily dependent on the core of the metropolitan area for the provision of jobs and services. However, newly built suburban shopping facilities to some extent disrupt this pattern, keeping some daily activities of inhabitants within the suburban zone. In addition to empirical observations, the key purpose of this contribution has been to discuss and apply time geography concepts and methods to the research of urban restructuring, and to understand the structuration of metropolitan spatial organization.

Introducing urban vitality as a determinant of children's healthy mobility habits: a focus on activity engagement and physical activity

In this study we introduce urban vitality as a determining factor for both physical activity (PA) and activity engagement in children living in Barcelona's Metropolitan Region. We compare the physical outcomes of children living in vital and non-vital areas using mobility data taken from a travel survey. Chi-square, and association tests were used to compare the health outcomes of children living in vital and non-vital areas. Specifically, we measured for activity engagement, walking for transport, minutes of PA and adequacy to World Health Organization PA recommendations. Results are stratified by age and gender and reveal how living in a vital area can produce up to 54 minutes more of PA per week, with a difference of nearly 20% in the number of outdoor activities undertaken. Neighbourhood vitality promotes healthier mobility habits, as children living in buzzing areas tend to engage in more activities and spend more minutes walking for transport.
