AbstractThe rise of modern sport in the mid-nineteenth century coincided with the emergence of photography as a new image-making medium. Thus, both practices developed in parallel. Notably, many early photographers turned to sport as a subject for their work, despite the early technological limitations of the medium. Histories of photography have, however, tended to overlook this. Similarly, sport historians have tended to regard these early photographs simply as illustrative material rather than important innovations in the formation of new visual conventions for the representation of sport. This paper seeks to redress this by exploring, in close detail, examples of sports photography produced in the mid- to late-nineteenth century. More importantly, it examines the visual vocabularies deployed by these early photographers within the context of contemporary art practices, demonstrating how artistry and artifice were deployed in the production of some of the earliest, and finest, examples of sports photography ever produced. 相似文献

ABSTRACTMargarita with a Straw is an Indian movie about a queer/disabled woman exploring her sexuality. The article uses textual analysis with a discursive formation approach to analyze how the protagonist’s queer/disabled identity is constituted vis-à-vis intimate partnerships alongside the promotion of neoliberal values. One relationship with an able-bodied white man takes place within a caregiving dynamic that challenges her independence. The other relationship with a disabled South Asian woman creates an interdependence that bifurcates their identities as disabled-and-queer. The article argues that the promotion of neoliberal values in the context of queer/disability is about independence from dependence on sociopolitical systems. 相似文献

Modern OCR engines incorporate some form of error correction, typically based on dictionaries. However, there are still residual errors that decrease performance of natural language processing algorithms applied to OCR text. In this paper, we present a statistical learning model for post-processing OCR errors, either in a fully automatic manner or followed by minimal user interaction to further reduce error rate. Our model employs web-scale corpora and integrates a rich set of linguistic features. Through an interdependent learning pipeline, our model produces and continuously refines the error detection and suggestion of candidate corrections. Evaluated on a historical biology book with complex error patterns, our model outperforms various baseline methods in the automatic mode and shows an even greater advantage when involving minimal user interaction. Quantitative analysis of each computational step further suggests that our proposed model is well-suited for handling volatile and complex OCR error patterns, which are beyond the capabilities of error correction incorporated in OCR engines. 相似文献

ABSTRACT The recruitment of athletes with limited resources is a global problem in professional sports. In US Major League Baseball, the experience of the Oakland Athletics’ general manager in the last decade turned his “Moneyball” model into a synonym of quantitative analysis in the transfer market of baseball players. His strategy focused on hiring players with outstanding technical skills but relatively low market value. This study adapted this model to the framework of a multiple criteria decision aid (MCDA), by selecting undervalued players who have complementary abilities. The novelty here refers to the joint use of four algorithms explored by the composition of probabilistic preferences (CPP) (i.e., ranking, classification, dynamic evaluation and regularity analysis) and their application to soccer player performance evaluation. The new model analysed the recent transfer of a left-back soccer player to Europe. The results indicated 12 opportunities for better investment, among 32 left and right-back players considered. Two years later, the value of the same player was considerably lower. He played only five matches in the 2018–2019 season, without scoring or providing any assists. On the other hand, the players better classified by the CPP-MB model presented higher performances and market values. 相似文献

ABSTRACT Fast bowling is categorised into four action types: side-on, front-on, semi-open and mixed; however, little biomechanical comparison exists between action types in junior fast bowlers. This study investigated whether there are significant differences between action-type mechanics in junior fast bowlers. Three-dimensional kinematic and kinetic analyses were completed on 60 junior male fast bowlers bowling a five-over spell. Mixed-design factorial analyses of variance were used to test for differences between action-type groups across the phases of the bowling action. One kinetic difference was observed between groups, with a higher vertical ground reaction force loading rate during the front-foot contact phase in mixed and front-on compared to semi-open bowlers; no other significant group differences in joint loading occurred. Significant kinematic differences were observed between the front-on, semi-open and mixed action types during the front-foot contact phase for the elbow and trunk. Significant kinematic differences were also present for the ankle, T12-L1, elbow, trunk and pelvis during the back-foot phase. Overall, most differences in action types for junior fast bowlers occurred during the back-foot contact phase, particularly trunk rotation and T12-L1 joint angles/ranges of motion, where after similar movement patterns were utilized across groups during the front-foot contact phase. 相似文献

ABSTRACTThis study examines the patterns of news engagement among news consumers with different political affiliation and cultural background. We use computational methods and data from Twitter in a cross-country comparison of engagement with six online news sources in Australia and South Korea. For our analysis, we used a subset of Twitter users who retweeted at least one political story during the period of collection, and for whom we were able to predict political affiliation using correspondence analysis and data on Twitter follower ties to politicians. We find that right-wing Australian retweeters are more intense in their news engagement, compared with their left-wing counterparts, whereas in South Korea it was the opposite. Australian right-wing political retweeters have more diverse information sources, while there was no difference in information diversity between the right and left in South Korea. We discuss how the political situation in South Korea at the time of data collection may have affected our analysis. We emphasise the methodological contributions of our research and its connection to on-going research into the behavioural foundations of ‘filter bubbles’. 相似文献

Britain’s exit from the European Exchange Rate Mechanism in 1992 and the Second Iraq War in 2003 are two infamous examples of disastrous policy, but governments blunder all the time – whatever party is in power. Infrastructure projects overrun. The aims and techniques of different departments clash. Scandals erupt among officials and politicians. Controversies stymie attempts at agreement and consensus. But why exactly do these failures happen? Are they more or less widespread than in the private sector? And can studying British governments’ decision-making across the twentieth century improve it in the future? In his May 2018 inaugural lecture, Professor O'Hara recommended a slow, deliberative, transparent, democratic and above all humble and sensitive approach in order to avoid another Black Wednesday or ruinous war – an approach in contrast to the populist tone of much recent debate. 相似文献

In this reflective piece the author focuses on the meaning that he made of inclusion in a book that was published almost twenty years ago. He then reflects on the meaning he makes of the current situation. He explores the problematic nature of the concept of inclusion, whether labels actually enable inclusion, research-informed implications of inclusion for those who do not experience SEND and the damaging impact of hyperaccountability and marketisation. He proposes that we may find future solutions by embracing complexities and educating for diversities. 相似文献
