Communities living on remote islands are often viewed as among the most exposed and vulnerable to climate change impacts. This study uses the Sustainable Livelihoods Framework to investigate how indigenous communities living on two physically different islands in Torres Strait, Australia, experience what they consider to be the impacts of climate change in relation to their daily lives. During this process, a series of natural, physical, and socio‐cultural limits and barriers to climate change adaptation were identified on Boigu, a low‐lying mud island inundated by the sea during high tides and storm surges. As a volcanic island, Erub's elevation is higher but significant community infrastructure, housing, and cultural sites are located on the low coastal fringe. No immediate limits to climate change adaptation were identified on Erub, but physical and socio‐cultural barriers were revealed. Limits to climate change adaptation occur when adaptation actions fail to protect the things valued by those affected, or few adaptation options are available. Barriers to climate change adaptation may be overcome if recognised and addressed but can become entrenched limits if they are ignored. Within the participating communities, such limits and barriers included (a) restricted adaptation options due to limited access to particular livelihood assets; (b) difficulty engaging with government processes to secure external support; and (c) people's place‐based values, which evoke a reluctance to relocate or retreat. 相似文献

This research, conducted with groups of undergraduate students before and after a European fieldwork exercise, critically examines the pedagogic value of fieldwork and its ability to provide students with transferable skills. This is achieved using Anderson and Erskine’s lens of tropophilia – the aesthetic connection between people and place – to explore the influence of “being” in the field upon affective learning. In doing so, this research suggests (1) that encouraging students to recognize how their own affective skills may influence the types of knowledge(s) that are produced on fieldtrips and (2) that people-place connections have the ability to inspire students to become more self-reflexive about their position(s) as learners. 相似文献

The literature on Indigenous participation in the Second World War from Canada, the United States, Australia and New Zealand has tended to portray Indigenous soldiers as exceptionally able and courageous in battle. While heart-warmingly laudatory and an understandable product of genuine evidentiary challenges in researching this subject, the image constructed is partial and unrealistic. At best it is misleading; at worst it conflates indigeneity and combat proficiency in ways that reinforce racial stereotypes of Indigenous people as ‘natural’ warriors prevalent during the war. This article argues that we discard the exceptionalism enshrouding Indigenous combat performance in favour of a more culturally nuanced approach. 相似文献

The British preference of Australian immigration policy was challenged by the demands of a rapidly expanding post-war programme overseen by the newly established Department of Immigration. An essential function of the department was the screening of prospective migrants against criteria shaped by national population policy preferences. This paper examines Australia’s post-war immigration security screening policies in domestic and international contexts. It compares the immigration department’s approaches to immigrating British subjects with their approaches to those from other national and ethnic backgrounds. We explain how assumptions about the free passage of British subjects across empire could persist until the 1970s despite revelations that Australian authorities were powerless to stop those with serious criminal histories gaining entry to the country. These revelations about risky British migrants exposed the limits of Australian control over entry and exclusion, while illuminating the emerging frameworks of post-war border controls. 相似文献

Poropat, S.F., Nair, J.P., Syme, C.E., Mannion, P.D., Upchurch, P., Hocknull, S.A., Cook, A.G., Tischler, T.R. &; Holland, T. XX.XXXX. 2017. Reappraisal of Austrosaurus mckillopi Longman, 1933 from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur. Alcheringa 41, 543–580. ISSN 0311-5518Austrosaurus mckillopi was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualized through CT data, validates it as a diagnostic titanosauriform taxon, tentatively placed in Somphospondyli, and characterized by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature that appears to be autapomorphic) and by the presence of a robust ventral mid-line ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the ‘Hughenden sauropod’) from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum.Stephen F.

This paper examines how hockey is used to construct and demarcate the Canadian national community from external others, namely, the USA, Europe and Russia/USSR. The paper suggests popular nationalist narratives around the sport of hockey construct difference from external others in ways that place them in tension with state and corporate interests. Drawing on the concept of everyday nationalism, this article explores how the interplay between international competition, national identity and commercial sport has made hockey an ambiguous and contested national symbol in Canada. 相似文献

Under the leadership of Matteo Salvini, the Lega Nord has shifted away from its previous political identity as a voice for Italy’s north and has placed hostility towards the policies and institutions of the European Union (EU) at the heart of its rhetoric. Nowadays, the enemy is Rome no longer: it is Brussels, European institutions, and the threat to the national sovereignty posed by the EU. Borrowing from the Italian political philosopher Nicola Matteucci, we would describe Salvini’s Lega as a ‘populist insurgency’. That is to say, it is a populist party that marries the traditional populist evocation of the virtues of the people against the corrupt elites, with a pervasive glibness of analysis. 相似文献

This article draws on Foucault’s concept of pastoral power to understand Filipino men’s care work and the making of migrant masculinities in Saudi Arabia. Feminist scholars have indicated the gendered nature of pastoral power and emphasized what Young refers to as the ‘logic of masculinist protection’ that characterizes the contemporary security state. However, the notion of pastoral power invites further consideration of the taken for granted cultural assumptions about the way that hegemonic masculinity and forms of homosociality are characterized mainly by aggression, competition and dominance. Men’s talk about and practical involvement in assisting fellow migrants in diasporic settings foregrounds the way that an ethics of care runs up against and is entangled with the competitive bonds of masculine solidarities. While markers of material success are privileged in measuring migrant men’s accomplishments in country of origin, practices of care become central to men’s achievement of symbolic power and social legitimacy especially among their peers in the diaspora. That spatialization is also linked to temporally shifting models of masculinity and normative expectations about men over the life course. 相似文献
