城市居民健康生活方式研究的时空行为视角

在宜居城市和健康城市的建设背景下,健康生活方式成为政府和公众共同追求的重要目标。已有的环境-行为-健康关系的研究主要从静态时空间的视角出发,探讨邻里环境要素与居民健康水平的相关关系,并分析健康相关行为或活动特征的中介作用。本文立足于个体导向和强调制约与企划的时间地理学、基于活动-移动模式的活动分析法、以及移动性转向下情境单元的选择问题,以个体整日活动-移动模式作为生活方式的外在行为体现,从时间、空间、个体行为和群体行为的角度,构建了基于移动性的城市环境暴露-日常活动移动模式-个体健康效应三者关系的综合分析框架,以期促进城市环境与社会的可持续发展。     

The Making(s) of an Alternative Urban Policy: What Happens When Free Fares Come to Town?

While many urban policies and practices claim to offer an “alternative” to the “mainstream” of urban entrepreneurialism, they remain under-theorised and prone to alignment with entrepreneurial agendas. In this paper I examine fare-free public transport (FFPT) as a salient example of an alternative urban policy. Looking at Aubagne (France) and Tallinn (Estonia), I explore what happens when an alternative policy “comes to town”. I detect how FFPT enters local urban regimes, and study the (non-)participation of public transport passengers and workers in the decision-making process about whether and how to abolish public transport fares. My analysis reveals that albeit alternative policies such as FFPT seem to oppose entrepreneurialism, they may hinge on urban regimes that span across institutions, leave the local configurations of power unchallenged, and strenghten local elites. The adaptability of alternatives to diverse political and intellectual positions explains their resilience. Consequently, their radical character cannot be taken for granted and remains an object of political struggle.     

Monks on the move? An assessment of mobility at the medieval Nubian monastery of Ghazali,Sudan (ca. 680–1,275 CE)

The location of Ghazali monastery away from the Nile valley within the relatively isolated environs of the Bayuda desert presents a landscape suggestive of mobility toward the monastery by those who chose to reside there as monks. To assess this potentiality, a sample of 37 individuals from the monastic cemetery (Cemetery 2) were analysed for ⁸⁷Sr/⁸⁶Sr and δ¹⁸O to assess residency during dental enamel formation. The data generated bring into question the nature of mobility to Ghazali monastery, particularly in regard to the potential movement of people from the Nile valley, adjacent desertic landscapes, and further afield.     

Great Ancestral Women: Sexuality,Gendered Mobility,and HIV among the Bamu and Gogodala of Papua New Guinea

Faced with a potentially devastating epidemic of HIV/AIDS in Papua New Guinea (PNG), sexuality and mobility have become a focus of national research and prevention programs. In Gogodala and Bamu communities in the Western Province, gendered mobility and sexuality intersect with ancestral narratives that form part of a wider series of Hero Tales found in the southern regions of PNG and Irian Jaya. In this paper we highlight the way these stories detail the travels and activities of female ancestors – known as Sagalu among the Bamui and Sawiya among the Gogodala. We outline the way such ancestral figures are now linked to understandings of contemporary STIs such HIV/AIDS as well as gendered mobility and sexuality more generally. Among the Bamu such links are sometimes directly asserted, with Sagalu represented as the origin if not cause of a uniquely defined variant of HIV/AIDS. Among the Gogodala, however, HIV/AIDS is predominantly understood as something external to the Gogodala and unrelated to ancestors like Sawiya. To explain this difference we note that, historically, Gogodala women have been less mobile and less transactable than their Bamu counterparts who have continued to enact unique understandings of the intersection of heterosexual marriage, gendered mobility, and illness. We argue that the mobility and sexuality of gendered ancestors is salient to understanding these contemporary enactments and their potential implications in light of the HIV epidemic in PNG.     

Women who DARE: driving attitudes and road experiences among ultraorthodox women in Israel

This study seeks to gain insight into a unique group, ultraorthodox women in Israel, and their views and attitudes on driving and road experiences. Ultraorthodox women are generally contending with spatial and mobility restrictions due to stringent gendered spaces and social norms in their communities. Specifically in Israel, throughout the ultraorthodox sector, women are strictly forbidden to drive. In this research, we put the emphasis on driving dilemmas that have received marginal attention both socially and empirically. A qualitative method was used, based on face-to-face in-depth interviews, with women from three major ultraorthodox communities. The findings reveal that the driving ban for ultraorthodox women in Israel generates ambivalence and conflict, and exacts a heavy social price. Moreover, in line with approaches of feminist geography, it raises issues of gender relations and cultural implications, such as restricting the space and the mobility of women in order to keep them in a subordinate position. The results are discussed in terms of gender roles, cultural exclusion, and spatiality, on both the practical and emotional levels. The study opens a window to a unique sector of the Israeli population, revealing unique dilemmas with which ultraorthodox women grapple daily in their community.     

What constitutes a ‘trip’? Examining child journey attributes using GPS and self-report

Active travel is associated with improved health and development outcomes in children. Accurate detection of children's travel behaviors and routes, however, is problematic. Travel diaries are often used to collect information on children's travel behaviors, yet no evidence for the accuracy of this methodology exists. This study investigated the validity of children's self-reported trips (origin, destination) compared with an objective criterion (global positioning systems units; GPS). Children (n = 10, 9–11 y) wore the GPS units for seven consecutive days between March and June 2011 and completed travel diaries daily with researcher assistance. Affinity group interviews were conducted in December 2011 with 30 children from two schools to garner perspectives on trip definition, neighborhood perceptions, and to illuminate GPS and travel diary findings. GPS journeys were manually compared with travel diary journeys for destination sequencing, start times, and travel mode. Accuracy in trip sequencing was compared by day type, and journey type using percentage differences and the chi-square (χ²) statistic. Of the 380 trips captured, 54.5% of journey sequences were fully or partially matched, 22.4% were GPS only trips and 23.2% travel diary only. Greater accuracy (full/partial match) was observed for weekdays than for weekend days and for the journey to or from school than for other journeys. Travel mode agreement existed for 99% of matched trips. Although children's travel diaries may confer contextual journey information, they may not provide completely accurate information on journey sequencing. Thematic analysis of affinity group data revealed that reasons for this are multifaceted, including differing concepts of what constitutes a ‘trip’. A combined approach of GPS and travel diary is recommended to gather a comprehensive understanding of children's journey characteristics.     

“We’ve Lost Our Bearings”: Place,Tourism, and the Limits of the “Mobility Turn”

Abstract: The “mobility turn” claims that conceding analytical priority to the study of mobility is the best way to overcome methodological approaches based on fixed and stable categories argued to be unviable in a world that is increasingly mobile. In this paper I argue that the mobility approach, far from reaching this goal, in fact reifies the cleavage between mobility and immobility, relegating immobility to a passive, undertheorized position, and collapsing the complex workings of power, thus foreclosing a dialectical understanding of the contradictory albeit co‐produced processes of mobilization and immobilization. Drawing on an ethnographic analysis of the impacts of changing patterns of accumulation of the tourist industry on the urban space of Palma (Majorca, Spain), I suggest a relational approach attentive to the dialectics of mobility and stability, continuity and change.     

“It's About Time You Came Out”: Sexualities,Mobility and Home

Abstract: Helping redress the dominance of metropolitan narratives upon which much literature on sexuality is framed, this article interprets the narrative told by a “white” 16‐year‐old man living in regional Australia. Our aim is to investigate the intersections of migration and homemaking in sexual subject formation. Finding a place to call “home” can be a complex process for young men born in regional Australia and not conforming to the social formations of a “normal guy”. This young man's narrative expressively reveals the fluidity and spatiality inherent in processes of negotiating sexual subjectivities. His story provides telling insights into how migration and mobility change his understandings of home and of self by making possible a third‐space configured by neither the gender norms of his hometown nor the “gay scene” in Sydney.     

Identifying locals, migrants, and captives in the Wari Heartland: A bioarchaeological and biogeochemical study of human remains from Conchopata, Peru

The site of Conchopata in the central Peruvian Andes was the secondary center in the heartland of the Wari Empire (AD 600–1000), and in this study we examine whether this urban locale was populated by locals, voluntary migrants from distant regions, and/or captives who were forcibly brought to Conchopata. We examine radiogenic strontium isotope ratios from 72 dental enamel and bone samples representing 31 formal burials and 18 human trophy heads to distinguish between locals and non-locals, and we examine skeletal and archaeological data to establish whether non-local persons were voluntary migrants or captives. We also describe a new, straightforward technique in the evaluation of radiogenic strontium isotope ratios to assist in detecting non-locals when large datasets are available.Results show that natal Conchopata inhabitants should exhibit radiogenic strontium isotope ratios that range from ⁸⁷Sr/⁸⁶Sr = 0.70548 to ⁸⁷Sr/⁸⁶Sr = 0.70610. Thus, among the 31 burials, 29 exhibit local values, suggesting that Conchopata was not a cosmopolitan center to which numerous foreigners migrated; rather, it was populated by local peoples, likely the descendants of the preceding Huarpa culture. The two individuals with non-local radiogenic strontium isotope ratios are an infant and a 17–22 years old female. The archaeological context suggests that the female may have been taken captive for subsequent sacrifice, as she was interred in front of the ritual D-shaped structure in which decapitated human heads (trophy heads) and sacrificed camelids were deposited. Among the 18 trophy heads sampled, 14 have non-local values, confirming previous studies of smaller samples that suggested that Wari warriors travelled to other locales and took captives—both adults and children—for subsequent transformation into trophy heads. Additional analyses of bone-tooth pairs from a subsample (12 burials and six trophy heads) shows that the burial group was much more sedentary (homogenous radiogenic strontium isotope ratios in bones and teeth) and the trophy head individuals were much more mobile (heterogenous radiogenic strontium isotope ratios in bones and teeth). Overall, the multiple lines of evidence support the notion that the Wari Empire occasionally used militaristic means, combined with elaborate ritualism, to subjugate other populations, a tactic that may have helped Wari establish and maintain control in particular regions in the Andes.     

Mobility-driven cultural transmission along the forager-collector continuum

Hunter-gatherers mobility regimes are often treated as discrete adaptive strategies. Here we present a model of forager mobility which treats collectors and foragers as two ends of a continuous spectrum. We show that a mobility regime can be situated along this spectrum by specifying the number of foraging moves a group makes before returning to its home base. The model allows us to explore the behavioural space between forager (i.e. residential mobility) and collector (logistical mobility) adaptations. We discuss the heuristic value of the model by showing how it can be used to make testable predictions about the impact of mobility strategies on archaeological measures such as occupation intensity and raw-material transportation distance. We then use the model to investigate the impact of mobility on rates of cultural transmission. We show that mobility-driven cultural transmission may be equivalent to a Poisson process and that the time it takes for a cultural behaviour to be transmitted between two mobile groups is optimized when the mobility regime is somewhere between pure forager and pure collectors adaptations. In addition, we find that rates of cultural transmission decline in a very regular way, as the inverse of the square root of the number of moves made before returning to home base. This suggests that there is a mechanistic connection between the mean-squared displacement of hunter-gatherers in space and the transmission of cultural traits.
