基于地方秩序嵌套的人类活动研究

活动的地方秩序嵌套"这一概念源于瑞典时间地理学者哈格斯特朗对人类活动复杂性及其背后蕴含的社会规则的思考,强调人类活动与其发生所需的时空资源配置之间的关系,隐含人类行为背后所需的各种资源在时间上的排列和空间上的组合规律。本文系统解读了"(活动的)地方秩序嵌套"的概念内涵、形成与符号表达,借助已有研究案例梳理不同地理空间尺度下地方秩序及其嵌套过程,以及目前这一领域的最新研究进展,在此基础上尝试提出这一概念在中国城市空间行为与规划中的研究与应用方向。     

居民社区活动空间共享的公共接触潜力测度方法

社区内的日常活动空间共享有利于创造居民面对面的社会接触,进而增进理解、提升社区信任和社区融合。基于行为地理学理论与方法,提出“物质空间—活动空间共享—社会心理空间”的关系路径,揭示社区居民的活动空间共享的研究意义;从结构、层级、尺度和载体四个角度构建居民社区活动空间共享的公共接触潜力分析框架;从社区和个体两个层级构建公共接触潜力测度方法,基于共同活动的联系衡量社区居民空间共享的广泛程度和频繁程度。在理论框架与指标测度的基础上,使用上海市郊区调查数据进行实证检验,分析了活动空间共享的社区差异和个体差异。研究指出,提升居民空间共享对建设充满人气的活力社区具有意义,能够为郊区社区生活圈建设和社区治理提供支持。     

上海城市老年人日常购物活动空间研究

购物活动是老年人日常生活中主要的活动类型之一,对老年人日常购物空间的研究是理解老年人与其周围商业环境相互作用的关键,然而目前国内这方面研究才刚刚起步。本文以上海城市老年人日常活动问卷调查的第一手资料为基础,首先对数据进行汇总得出了上海城市老年人日常购物活动的发生频率、出行距离等总体特征。然后进一步细化,分别总结出各小区老年人的日常购物活动空间模式并进行对比分析,发现市中心老年人的日常购物活动空间比较紧凑,而郊区老年人的日常购物活动空间则相对分散。最后着重从上海市的商业空间及零售业态的变革、商业设施的可达性、老年人购物决策过程三个方面对这种差异性进行了解释。     

Spondylolysis in a pre‐contact San Francisco Bay population: behavioural and anatomical sex differences

Spondylolysis refers to a separation of the spinal body from the arch. Researchers have documented that these fractures occur due to stresses related to activities involving the lower limb and back. Spondylolysis in sacral and lumbar vertebrae of 146 (66 males, 66 females, 14 indeterminates) California Amerinds were examined to determine whether sex differences were present. Sacral anatomy (i.e. sacralisation and lumbarisation, sacral base angles, and superior facet morphology) was analysed in relation to spondylolysis and sex, to explore whether sex differences could be better explained through activity patterns or anatomical variation. Spondylolysis afflicted 24 individuals (16.4%). Males had more than twice the rate of spondylolysis than did females (26% and 11%, respectively). Activity patterns, such as thrusting and throwing shafted obsidian points, could explain the sex differences. Males were most frequently buried with obsidian point artefacts, whereas females were buried with mortar and pestles. For sacral anatomy, only males had lumbarisation, and all other anatomical variation had no significant sex differences. Lumbarisation related to spondylolysis in males. In this study, sacral anatomical variation could not fully account for sex differences in spondylolysis; activity patterns provided a better explanation. Nonetheless, anatomical variation may predispose males to spondylolysis, or spondylolysis may affect sacral anatomy. Copyright © 2008 John Wiley & Sons, Ltd.     

The relationship between school ground design and intensity of physical activity

In this study, we investigated the relationship between school ground design and children's physical activity levels. In particular, we were interested in understanding the contribution of ‘green’ school ground design to physical activity levels. Data for this study were collected at an elementary school in Australia and in Canada. At each school, scans of Target Areas were completed to record the students' location and intensity of physical activity, based on the System for Observing Play and Leisure Activity in Youth (SOPLAY) (Australia: 23 scans, 6 Target Areas; Canada: 18 scans, 7 Target Areas). At both schools, the highest percentage of children present was engaged in vigorous physical activity on the manufactured equipment (42% of children/scan). Similarly, at both schools, the green area encouraged the highest percentage of children present to be engaged in moderate physical activity (47% of Australian children/scan, 51% of Canadian children/scan). The patterns of sedentary behavior differed slightly between countries. At the Australian school, the paved sporting courts (57%) and the paved canteen courtyard (50.5%) promoted the highest degree of sedentary play. At the Canadian school, the treed grassy berm (42%) and the treed concrete steps (43%) encouraged the highest percentage of sedentary behavior, followed by the open asphalt (34%). These results are also discussed in light of gender distribution. We conclude with a discussion of the design and cultural factors that influence children's physical activity on school grounds. We argue that if school grounds are to realize their potential to promote physical activity, they should include a greater diversity of design features and ‘green’ elements that engage children of varying interests and abilities in active play.     

Physical activity and rural young people's sense of place

This paper explores rural young people's perceptions of their local environments in relation to their experiences with physical activities through the use of visual methodologies. The main findings from map, photo and interview data from 13 rural young Australians included the importance of friends, family, and gender structures which are discussed in relation to developing a sense of place and how this shapes their experience in physical activities. The findings highlight the importance of sociocultural issues and raises questions regarding measuring physical activity prompting further qualitative research to inform sustainable and equitable physical activity promotion initiatives for rural young people.     

Atlantic networks,antagonisms and the formation of subaltern political identities

This paper engages with historians Peter Linebaugh and Marcus Rediker's account of the connections and circulations which they argue constituted a multi-ethnic Atlantic working class in the seventeenth and eighteenth centuries (Linebaugh and Rediker , ). Their stories of the mobile, networked insurgencies that traversed the early modern Atlantic challenge accounts of the geographies of resistance and labour which treat ethnicities as given and sealed, view subaltern movements as trapped in place and privilege the boundaries between spatial scales. This paper sketches some preliminary aspects of an agenda for thinking spatially the political identities constituted through Atlantic resistances. The paper foregrounds the multiple antagonisms constituted through Atlantic subaltern resistances to explore three aspects of the formation of subaltern political identities in the early-modern Atlantic. Firstly, how the spatial relations of Atlantic networks were brought into contestation through subaltern struggles. Secondly, the plural and mobile character of antagonisms between and within subaltern groups. Finally, the paper explores how subaltern agency and identities were formed in relation to the materialities of Atlantic networks. These arguments are developed through discussion of subaltern resistances in and between Ireland, Newfoundland, the West Coast of Africa, the Virgin Isles and London in the eighteenth century.     

Context and spatial organization of the Clovis assemblage from the Topper site,South Carolina

Abstract

This paper reports results of a 40 sq m block excavation of the Clovis assemblage from the Topper site, South Carolina. Topper is one of only three buried, extensively excavated Clovis quarry-related sites in North America. The Clovis assemblage was recovered in a buried component distinct from overlying Archaic and Woodland components. The site geomorphology and formation processes and the horizontal distribution of the assemblage are used to identify a workshop floor with discrete knapping loci created by unique production and use goals. The excavated assemblage from Topper provides useful and important information in order to reinterpret the Clovis occupation of the Southeast. Moreover, spatial patterning from Topper shows Clovis people organized and structured onsite activities at quarry-related sites.     

Between‐group Differences in the Patterning of Musculo‐skeletal Stress Markers: Avoiding Confounding Factors by Focusing on Qualitative Aspects of Physical Activity

This paper presents a method for studying between‐group differences in physical activity patterns through the analysis of musculo‐skeletal stress markers (MSM). The specific aim was to develop a method that could overcome the problems related to confounding variables such as body size by shifting the analytical focus from the comparison of differences in intensity to the comparison of differences in kinds of activity. Instead of testing whether there are differences in the measures of central tendency of MSM scores between two groups, we proposed looking for differences in MSM covariation patterns. Formally, this is achieved through the statistical comparison of group‐specific MSM intercorrelation matrices. The null hypothesis is that the matrices are equal, and the statistical significance of the test statistic is obtained with a permutation test. In this way, the problem of confounding variables such as body size is mostly avoided because the procedure is based on the comparison of group‐specific sets of correlation coefficients which are scale‐free. The method was employed in a case study to investigate the differences in activity patterns between men and women from the Early Bronze Age population buried at the necropolis in Mokrin, Serbia. The null hypothesis of no difference between the male and female MSM correlation matrices was rejected (p = 0.0135). After the statistical significance of the difference was established, further investigation of male and female activity patterns was undertaken by means of principal component analysis (PCA) with varimax rotation. PCA results suggest that covariation between MSMs is stronger in the male sample. Success in demonstrating differences in activity patterns between sexes implies that the proposed method can be used to test for differences in physical activity between groups of individuals defined by criteria other than sex.
