The circulation of mobile professional athletes, a phenomenon whose visibility increased exponentially in the last couple of decades of the twentieth century, poses important questions for postcolonial approaches to the human condition. At first glance, the orientation of entire segments of the population in some countries in the global South to the possibility of migrating to sport careers in the global North seems to reproduce patterns of economic dependence of the world's peripheries on the world's centres, with the latter obtaining resources from the former in non-reciprocal fashion. A more nuanced approach, however, demands that these dynamics be framed in a broader context of multiple power relations that are at once local and global, material and ideational, and rooted in complex histories that have somewhat obscured colonial relations of yesteryears. This approach is illustrated here with materials about migration-oriented football academies in West Africa and the transnational circulation of Pacific Island rugby players.  相似文献

Several studies have assessed whether funding of disease specific research is in line with their burden. The authors of these studies concluded that the burden of a disease was a good predictor for its associated research funding. However, previous analyses did not take into account diseases that mainly affect people living in low income regions, i.e. so-called diseases of poverty. Moreover, the analyses were only performed for the burden diseases cause in high income countries. We investigated whether the conclusions about the relationship between burden and funding still holds when (1) including diseases of poverty and (2) accounting for the burden of diseases in low income countries. We found that the relationship between the burden and the level of diseases specific funding decreases for people living in low income countries. We find the best predictor for the level of funding to be the mortality in high income countries. In contrast to previous studies, we were able to include more diseases into our analyses (74). This enabled us to discover differences in funding levels between and within groups of diseases. we found that research on cancers was over funded with respect to the associated burden. In contrast, diseases of poverty systematically receive less funding than would be expected based on their burden. Other groups of diseases (cardiovascular diseases and mental illnesses) contained both over and under funded diseases.  相似文献

We introduce fast filtering methods for content-based music retrieval problems, where the music is modeled as sets of points in the Euclidean plane, formed by the (on-set time, pitch) pairs. The filters exploit a precomputed index for the database, and run in time dependent on the query length and intermediate output sizes of the filters, being almost independent of the database size. With a quadratic size index, the filters are provably lossless for general point sets of this kind. In the context of music, the search space can be narrowed down, which enables the use of a linear sized index for effective and efficient lossless filtering. For the checking phase, which dominates the overall running time, we exploit previously designed algorithms suitable for local checking. In our experiments on a music database, our best filter-based methods performed several orders of a magnitude faster than the previously designed solutions.  相似文献

Irisin is a myokine that is thought to be secreted in response to exercise that may help to prevent obesity and maintain normal glucose metabolism. In this study we investigated the associations between irisin and glucose homeostasis in middle-aged, overweight and obese men (n?= 144) with impaired glucose regulation, and the impact of exercise training on these relationships. The participants underwent 12 weeks of resistance or aerobic (Nordic walking) exercise training three times per week, 60 minutes per session. Venous blood (n?=?105) and skeletal muscle samples (n?=?45) were obtained at baseline and post-intervention. Compared to controls, Nordic walking, but not resistance training, increased irisin levels in plasma (9.6?±?4.2%, P?=?0.014; 8.7?± 4.9%, P?=?0.087; respectively) compared to controls. When considering all subjects, baseline irisin correlated positively with atherogenic index of plasma (r?=?0.244, P?=?0.013) and 2-hour insulin levels (r?=?0.214, P?=?0.028), and negatively with age (r?=??0.262, P?=?0.007), adiponectin (r?=??0.240, P?=?0.014) and McAuley index (r?=??0.259, P?=?0.008). Training-induced FNDC5 mRNA changes were negatively correlated with HbA1c (r?=??0.527, P?=?0.030) in the resistance training group and with chemerin in the Nordic walking group (r?=??0.615, P?=?0.033). In conclusion, 12-weeks of Nordic walking was more effective than resistance training in elevating plasma irisin, in middle-aged men with impaired glucose tolerance. Thus, the change in irisin in response to exercise training varied by the type of exercise but showed limited association with improvements in glucose homeostasis.  相似文献

In September 1939, two days before declaring war on Germany, the British government evacuated over half a million children from London to supposedly safer areas in the country. Schoolchildren went there with their teachers and infants with their mothers. Immediately after the event (and ever since) the impact of the evacuation on the children – the hardships of some and the adventures of others – has been extensively researched, as has been the operation’s broader social impact. Meanwhile, the policy ontology of the evacuation’s organisation remains surprisingly under‐researched. This paper explores how the planning for the evacuation developed in a brief period before the outbreak of the Second World War, in order to assess responsibilities for its shape and ultimate execution. At the core of this article is the evaluation of four sets of documents from the archives of the London County Council about the evacuation’s planning stages in the 1930s. Contrary to earlier claims that the administration of the children’s evacuation was not only a success, but also an excellent illustration of co‐ordinated planning and execution, it will be the conclusion here, that not co‐operation and co‐ordination at government and civil service level made London’s evacuation a logistical success, but the relentless drive by the London County Council, who pushed for the evacuation in the face of opposition from central government.  相似文献

Late nineteenth-century German–English rivalry changed attitudes in Hamburg. Previously, the once fiercely independent city and its burgeoning mercantile middle class had developed an Anglophilia that justified Hamburg being labelled a ‘London suburb’ and ‘the most British town on the Continent’. The affinity for all things English – from liberal politics to refined fashion sense – had developed on the back of close business links by seafaring merchant adventurers, Hanseatic traders and shipping magnates. Only hesitantly did the people of Hamburg join Bismarck’s Germany, but the prospect of war demanded a drastic shift towards German patriotism. Pragmatically, the Hamburg bourgeoisie complied – and severed their intellectual and emotional bond with England. This paper investigates the extent of Hamburg’s compliance by looking at essays that were produced at extreme ends of academe. The key sources are 1913 Abitur examination essays by secondary school students on the topic ‘England and Germany – two rivals’. They are assessed here alongside a 1914 public lecture from the English faculty at Hamburg’s university. The dual ambition of this study is to examine how Hamburg’s intelligentsia coped with new loyalties brought on by changing political contexts and to assess the validity of school essays and examination papers as historical sources (in so far they must be considered a niche interest). In many ways the results are sobering. While at university level Anglophilia prevailed in a strange form of nostalgia for a great Britain of peaceful gentlemen and honest workers, who should have resisted the imperial ambitions of a corrupt banking elite that provoked the war, the students’ essays almost betray Hamburg’s heritage by simply repeating the popular and one-dimensional propaganda about warmongering British imperialists attempting to suffocate Germany’s earnest ambitions for its rightful place on the world stage. On paper at least, German nationalism had thoroughly replaced Anglophilia. There are, however, indications that while teachers and students were compliant with current popular opinion, they did not expect it to last: the England-bashing essays are written in perfect English. A lot of time and effort went into the study of English, which surely would have been superfluous if Anglo-German relations were not expected to improve again soon. Seen as a whole then, students’ essays can be valuable sources – if one looks beyond their content.  相似文献
