This paper examines the question what kind of ethics prevail in contemporary urban transport planning and what potential does an ethics of care hold for practice? Researchers have given ample attention to the need for better governance and coordination, and despite acknowledging the need to reduce reliance on private cars, little has been said by them about what ethics can or should guide planning to bring about such frameworks for caring. This area of research merits urgent work given our collective need to address the socio-spatial, climate, and health impacts of car dependence. Taking as our focus transport planning in Victoria, Australia, we consider how an ethics of care could open new ways to redress how transport planning has perpetuated injustices in metropolitan Melbourne. We draw on secondary research to consider both the conditions that cultivated the current transport planning landscape and pathways for possible change that lie ahead. The research highlights opportunities to consider care as an ethical framework for transport planning that could amplify justice and equity claims in urban transport planning for Australian cities and that has salience for other cities elsewhere.  相似文献

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

Ancient human migrations provide the critical genetic background to historical and contemporary human demographic patterns. However, our ability to infer past human migration events, especially those that occurred over rapid timescales, is often limited. A key example is the peopling of Polynesia, where the timing is relatively well defined, but the exact routes taken during the final stages and the source populations are not. Here, we discuss the technical limitations of current methods for inferring rapid human migration events, using the final stages of Polynesian migration as an example. We also introduce a promising new proxy method to infer human migrations—patterns of bacterial evolution within ancient dental calculus (calcified plaque). While we focus on Polynesia, this method should be applicable to other past migrations, enhancing our understanding of human prehistory and revealing the crucial events that shaped it.  相似文献

Recent excavations in south‐eastern Wadi ‘Araba in Jordan have revealed the first early Islamic‐period copper‐smelting site known in the eastern side of the valley, which extends south of the Dead Sea to the Gulf of ‘Aqaba. Five test pits were excavated in 2012 at Khirbat al–Mana‘iyya, a prominent copper‐smelting camp in south‐eastern Wadi ‘Araba, Jordan. The results of these excavations demonstrate that the site was primarily active in the seventh–ninth century AD. Its distance from the copper sources of south‐west ‘Araba suggests that its location was chosen based on proximity to wood and water resources, rather than copper ore deposits. The discovery that the site dates to the early Islamic period has implications for previous and future work in south‐east ‘Araba. In particular, it challenges the common—until now—view of the region as virtually devoid of settlement during this period.  相似文献

While Indonesia’s efforts at countering violent extremism have enjoyed some successes, a section of its Islamist community remains committed to militant jihadism. The return from overseas of hundreds of militants linked to ISIS means that there is now a greater need than ever for interventions to prevent radicalisation – and for programs to reintegrate militants back into society. Drawing on 20 selected interviews with former jihadists, this article asks how successful official efforts have been at disengaging those convicted under Indonesia’s Anti-Terrorism Law from violent extremism. A significant minority remain welded to a militant mindset: “committed jihadists” who are likely to reoffend. Some former jihadists have “disengaged provisionally” but remain vulnerable: they have only disengaged for tactical or practical reasons. Yet some have also begun to disengage emotionally. While they may not disavow completely the use of force, these “provisionally deradicalised” activists have moved closer to that minority of interviewees who are “fully deradicalised”. Using this four-part typology of the pathways by which some militant jihadists have disengaged but others have not, this article finds that disengagement is a gradual process shaped by social networks. Consequently, it is suggested that a variety of methods be used to promote disengagement both before and after inmates leave prison.  相似文献

ABSTRACT

Kettle Falls, located 1125?km from the mouth of the Columbia River in present-day Washington State (USA), was the second-most important salmon fishing and trading locus on that river in the early historic era. We encapsulate the late Holocene history of the fishery by deriving a summed probability distribution function (SPDF) from 50 radiocarbon ages from 13 archaeological sites within 2?km of the falls. When compared to an SPDF from 307 sites from elsewhere on the Columbia Plateau, and a null model, the Kettle Falls SPDF exhibits two phases of elevated activity at 1700–1300?cal BP and 800–500?cal BP, and an intervening lull. These phases are not related to the excavation history or differential exposure of sites to taphonomic processes, but they are concordant with episodes of glacial advance in the local mountains, which reflect hemispheric-scale changes in climate. Modern returns of summer-run Chinook salmon to the Columbia River are inversely correlated with sea-surface temperature regimes in the northeast Pacific Ocean, and we propose that the occupational history of the Kettle Falls fishery echoes long-term variations in the returns of salmon to the upper Columbia River linked to climate change.  相似文献
