Cycling has cut across public health and policy forums in the last decade given trends in urban governance for liveability and uptake of cycling during the COVID-19 pandemic. This review discusses work that helps understand where, how, and why time spent cycling can contribute to health and well-being. The review discusses how cycling geographies offers an alternative to biomedical approaches that measure the risks versus the medical benefits of riding a bike. The paper is structured around three key themes that characterise contemporary cycling geographies (a) cycling and neoliberalism; (b) cycling citizenship; and (c) everyday cycling. The paper argues, these studies have not gone far enough in understanding the relationship between well-being and cycling. To help address this gap the review offers a ‘mobile territories of well-being’ framework. To conclude, consideration is given to the policy implications of a cycling geographies research agenda engaging with a mobile territories of well-being framework. 相似文献

Stable isotopic analysis of palaeontological and archaeological biogenic apatite carbonates from herbivorous mammalian species represents an important tool for worldwide palaeoecological research. Tooth enamel carbonates are more resistant to taphonomic processes than bone or dentine carbonates but are not invulnerable to diagenesis. As such, they require careful preanalytical processing that considers depositional environment and age. An established part of this process includes a weak acid treatment to remove soluble exogenous carbonates; however, published treatment times for isotopic studies of archaeological tooth enamel are variable and range from 15 min to over 8 hr. This study tests three different pretreatment protocols on modern and Pleistocene age archaeological kangaroo teeth (dating from contemporary to 46,000 bp ) to assess the effect of acid treatment time on isotopic integrity. The results indicate that treatment time is a critical parameter for producing consistency across results and shorter pretreatments of 4 hr or less are preferable for removing diagenetic carbonates while minimising alteration of the biological signal. 相似文献

The advertising of unhealthy food and beverages forms an important component of obesogenic environments. Such marketing to children is a key health determinant because of its impact on dietary preference and food purchasing behaviour. The location of outdoor advertising is important in exploring obesogenic environments and children's neighbourhoods. The aim of this study is to explore issues involved in the use of Google Street View to examine outdoor food and beverage advertising. The implications for using Google Street View in the context of neighbourhood built environment research and grass‐roots advocacy are discussed. The study was conducted within walkable distances from 19 primary and intermediate schools in Auckland, New Zealand, where “walkable” was defined as limited by 800 m road network boundaries, which are equivalent to school buffer boundaries. Google Street View allows for centrality of data collection, coding, and storage. However, challenges exist with the method because 727 (29.4%) of a total of 2,474 outdoor advertisements that were identified were not able to be categorised because images were unclear, not in English, blocked, or at angles where detail cannot be deciphered. Specific to outdoor advertising for food and beverages, the results presented here show that children are exposed to a significantly greater number of unhealthy advertising than other advertising, P=0.001, eta‐squared statistic (0.45) indicates a large effect size. Overall, the results show promise for the use of Google Street View in the study of obesogenic environments. 相似文献

Taking a feminist-phenomenological perspective of the body, this article provides an empirically grounded analysis of the embodied subjectivity of women in the movement against hydropower plants (HPPs) in the culturally and spatially specific context of the Eastern Black Sea region of Turkey. Informed by a feminist engagement with Merleau-Ponty’s concepts of ‘the body-subject’, ‘the flesh’ and Einfühlung, the article places subjectivity within a relational ontology of sentience and intelligence in which corporeal experiences, senses and affects condition cognitive and agential processes. Bodily senses and affects are thus treated as media of subjectivity. The relationship between water and identity, established through memory, heritage and history, is also produced and/or conserved by the embodied relation between women’s bodies and bodies of water, within the connective ‘flesh’ of the physical world. The case of the Eastern Black Sea demonstrates how political subjectivity of women in the movement against HPPs is conditioned by an intimate embodied relationship with river waters that is sustained by a series of sensory-affective experiences. Their statements emphasize, over and over again, an interconnectedness with the rivers, which makes the cause of anti-HPP struggle vital and urgent for them. This feeling of urgency is a source of women’s radicalism in opposing HPPs. The article maintains the female subject as embodied and transversal, and stresses the centrality of corporeal experience, sense and affect in formation of political subjectivity. By developing a body-centred feminist-phenomenological approach to political subjectivity, it introduces a novel way of analysing women’s activisms within and beyond environmental movements. 相似文献

AbstractThis essay offers a critical analysis of the ‘culture and sustainable development’ discourse, notably among cultural activists and in actually existing cultural policy. It interrogates the utility of the narrative, seeks to uncover the semantic manoeuvres it employs and challenges the conventional wisdom it represents. The essay first explores the itinerary of the ductile notion of ‘sustainability’, the ways in which it has been stretched far beyond the original intent of those who coined the term, and identifies the conceptual discontents that this semantic multiplication has entailed. It hypothesizes that precisely because the term ‘sustainable’ and its derivatives are so acceptable and malleable at the same time, they have been easy to yoke to the bandwagon of the many-faceted and totalizing process that is ‘development’, allowing many different actors to project their interests, hopes, and aspirations under this composite banner. The essay then analyses the campaign to make culture ‘the fourth pillar of sustainability’ under the banner of the movement called ‘Agenda 21 for Culture’. It concludes with a plea for a return to the original ecological focus of the term ‘sustainability’ – notably as regards climate change – and outlines some cultural policy responses such a focus can and should generate. 相似文献

In this article, I focus on the construction and restoration of houses in the Catalan Pyrenees, on their materiality, and specifically on the relationship between architectural and heritage processes that shapes them. I provide an analysis of how architectural forms, norms and regulations, as well as building aesthetics and materials, were transformed in the past decades following a parallel process of changes in the region. The aim is to explore the relationship between the built environment and the cultural and economic shift of the area in recent times. Drawing on extensive ethnographic research conducted in a valley of the Catalan Pyrenees, I show how the material culture, architecture and built environment evolved in close relationship to the spread of heritage discourses leading to a mutually constituting association that helped shape the elements of the new social realities. 相似文献

Lions reached their northernmost distribution in the Carpathian Basin at a time when the climate turned cooler and drier and the complex Late Neolithic settlement network, marked by human populations concentrated on and around tells, disintegrated. A perforated distal phalanx and a calcaneus of lion (Panthera leo L., 1758) from two different Copper Age (5th–4th millennium cal BC) settlements in Hungary contribute to mapping the distribution of Holocene lions in southeast Europe. Previous discoveries of lion bones (representing all parts of the body) have offered evidence of local lion hunting and probable consumption. The new finds also illustrate the cognitive significance of lions and help reconstruct their phenotypic size. The perforated phalanx discussed in this paper represents the large dewclaw of a powerful male, the first ever worked lion bone available in Hungary. The calcaneus offers additional metric information interpreted in light of measurements taken on extant individuals from both Asia and Africa. Inseparable environmental and cultural factors leading to the occurrence and extinction of prehistoric lions in the Carpathian Basin are reviewed in light of these new data. 相似文献

This study uses service area–based coverage and various count regression methods to assess neighbourhood-level healthy and unhealthy food environments, and food access associated with different socio-economic groups in Edmonton, Canada. We identify three types of vulnerable neighbourhoods according to different food environments: food deserts (i.e., neighbourhoods lack sufficient access to healthy foods); food swamps (i.e., neighbourhoods have excess access to unhealthy foods); and those with overlaps of food swamps and food deserts. We also identify neighbourhoods with superior access to healthy foods (i.e., food oases). Additionally, our results from regression analyses indicate: (1) child population is negatively associated with both healthy and unhealthy food resources; (2) good access to public transportation is associated with good coverage of all healthy food outlets and convenience stores; and (3) deprived neighbourhoods with higher percentages of minority populations have better coverage of both healthy and unhealthy foods in general. The results from this study can help the City of Edmonton identify the key neighbourhoods with high potential for local business and the hotspot neighbourhoods that require particular support. Tailored strategies are proposed to effectively and efficiently improve food environments with limited resources. 相似文献

AbstractTourism research is starting to take interest in the psychology of environmental distress, particularly as it relates to climate change. For both the COVID-19 pandemic of 2020 and the climate change movement that dominated international media in 2019, psychological parallels exist in terms of our experience of loss. As the world grapples with the pandemic and tourism grinds to a halt, stories on social media are surfacing that claim wildlife is returning to quarantined cities and that the Earth is healing itself. Much of the implicit critique of these stories is directed at the tourism industry, with two viral posts in particular supposedly documenting the ‘rewilding’ of Venice, that infamous icon of overtourism. While the popular media have been concerned primarily with the factual accuracy of these claims, what has gone largely unexplored is the apparent desire for environmental reparation that they express. The fixation on environmental healing evidenced in tourist social media can be interpreted as a response to widely-felt ‘ecological grief’, triggered by the events of COVID-19. In this context, animal reclamation of urban spaces can be identified as a motif of environmental hope that symbolises life, regeneration and resilience, the understanding of which may contribute to the project of hopeful tourism in the post-COVID-19 era. 相似文献

江南地区的圩田大致滥觞于三国之际,迅速发展于两宋,全盛于明清,是我国江南人民在长期治田治水实践中创造的农田开发的一种独特形式。文章以大量历史文献资料为基础,全面考察了江南地区圩田开发的历程与特点,研究了江南圩田兴盛的历史因素和自然条件,并简要分析了圩田的作用。在此基础上,具体探讨了圩田开发对生态环境所造成的影响,认为因过渡围垦破坏了江南地区原有的湖泊河流水文环境,造成“水不得停蓄,旱不得流注”的严重局面,这便给圩田大大增加了防患水灾的压力;历代地方政府在圩田管理方面也是各自为政,各地圩田缺乏相互间的协作,使因破圩而形成的局部水灾年年有之;大量构筑圩田,使湖泊面积大为缩小,影响其调节水量的功能,破坏了本地区的生态条件,致使灾害频频发生。此外,围湖特别是废湖以后,使众多的水生资源也遭到了严重破坏。 相似文献
