Tropical forcing of increased Southern Ocean climate variability revealed by a 140-year subantarctic temperature reconstruction

Occupying about 14% of the world's surface, the Southern Ocean plays a fundamental role in ocean and atmosphere circulation, carbon cycling and Antarctic ice-sheet dynamics. Unfortunately, high interannual variability and a dearth of instrumental observations before the 1950s limits our understanding of how marine-atmosphere-ice domains interact on multi-decadal timescales and the impact of anthropogenic forcing. Here we integrate climate-sensitive tree growth with ocean and atmospheric observations on southwest Pacific subantarctic islands that lie at the boundary of polar and subtropical climates (52-54°S). Our annually resolved temperature reconstruction captures regional change since the 1870s and demonstrates a significant increase in variability from the 1940s, a phenomenon predating the observational record. Climate reanalysis and modelling show a parallel change in tropical Pacific sea surface temperatures that generate an atmospheric Rossby wave train which propagates across a large part of the Southern Hemisphere during the austral spring and summer. Our results suggest that modern observed high interannual variability was established across the mid-twentieth century, and that the influence of contemporary equatorial Pacific temperatures may now be a permanent feature across the mid- to high latitudes

The new Victorians? Celebrity charity and the demise of the welfare state

This article asks whether the expansion of celebrity involvement in charitable and humanitarian issues in Northern Europe and the US might be a comparable historical phenomenon with the philanthropic endeavours of prominent nineteenth-century persons. The article notes that the conspicuous nature of star philanthropy in both Victorian times and the present is fairly dramatic in comparison with that of the mid twentieth century, when the welfare state and the New Deal were at their peak: a welfare-oriented era which, to some, now increasingly looks like a ‘historical blip’. It asks whether the rise of contemporary celebrity involvement in charity can therefore be explained in terms of the contemporary political conjuncture, inasmuch as celebrities could be understood as individuals with large amounts of private capital seeking to intervene in – and gain forms of power through – involvement in humanitarian and charitable causes that might have formerly been the job of the state. Can celebrity involvement in charity be explained in these terms? Does the marriage of celebrity and charity today take a neoliberal form, one that parallels the liberal form of nineteenth-century interventions, bequests and donations? What might the key differences between forms of spectacular ‘philanthrocapitalism’ in these eras (particularly the contemporary insistence on the confessional and intimate modes of address) reveal about its workings, its internal traditions and about the specificity of our own age? This article draws on contemporary media discourse, debate in the voluntary sector, historical scholarship and Foucault’s distinctions between liberalism and neoliberalism to argue that whereas ‘celanthropy’ in the Victorian period eventually came to contribute to the welfare state, today it is more involved in privatising and dismantling it

Inequalities and Agencies in Workplace Learning Experiences: International Student Perspectives

The final publication is available at Springer via http://dx.doi.org/10.1007/s12186-016-9167-2National systems of vocational education and training around the globe are facing reform driven by quality, international mobility, and equity. Evidence suggests that there are qualitatively distinctive challenges in providing and sustaining workplace learning experiences to international students. However, despite growing conceptual and empirical work, there is little evidence of the experiences of these students undertaking workplace learning opportunities as part of vocational education courses. This paper draws on a four-year study funded by the Australian Research Council that involved 105 in depth interviews with international students undertaking work integrated learning placements as part of vocational education courses in Australia. The results indicate that international students can experience different forms of discrimination and deskilling, and that these were legitimised by students in relation to their understanding of themselves as being an ‘international student’ (with fewer rights). However, the results also demonstrated the ways in which international students exercised their agency towards navigating or even disrupting these circumstances, which often included developing their social and cultural capital. This study, therefore, calls for more proactively inclusive induction and support practices that promote reciprocal understandings and navigational capacities for all involved in the provision of work integrated learning. This, it is argued, would not only expand and enrich the learning opportunities for international students, their tutors, employers, and employees involved in the provision of workplace learning opportunities, but it could also be a catalyst to promote greater mutual appreciation of diversity in the workplace
