The Cross-Language Evaluation Forum has encouraged research in text retrieval methods for numerous European languages and has developed durable test suites that allow language-specific techniques to be investigated and compared. The labor associated with crafting a retrieval system that takes advantage of sophisticated linguistic methods is daunting. We examine whether language-neutral methods can achieve accuracy comparable to language-specific methods with less concomitant software complexity. Using the CLEF 2002 test set we demonstrate empirically how overlapping character n-gram tokenization can provide retrieval accuracy that rivals the best current language-specific approaches for European languages. We show that n = 4 is a good choice for those languages, and document the increased storage and time requirements of the technique. We report on the benefits of and challenges posed by n-grams, and explain peculiarities attendant to bilingual retrieval. Our findings demonstrate clearly that accuracy using n-gram indexing rivals or exceeds accuracy using unnormalized words, for both monolingual and bilingual retrieval. 相似文献

This chapter discusses the role conflict of the educational researcher who comes upon an unprofessional relationship between teacher and pupil. It is argued that the whistleblowing literature in related professions, with its focus on standard conditions and solutions framed as obligations, is inadequate. Reference is made to the idea of 'guilty knowledge': the feelings of guilt that attach when one comes to know of harm visited on innocent others, and has no unqualified sense of which way to act. Distinguishing moral from causal responsibility helps to show how blame need not necessarily attach to the guilt-ridden researcher, whichever option she chooses. 相似文献

The Access and Equity Programme at the University of Southern Queensland is an example of a program supported by the Commonwealth Government's Higher Education Equity Programme. The characteristics of this program are discussed in terms of its context, focus and rationale, structure and components, and outcomes. The program is seen to be successful in fulfilling the aim of such programs to promote greater access to higher education from disadvantaged groups. However, it is also concluded that: the required focus on defined target groups can itself be inequitable by ignoring cases of individual disadvantage; the need for quota selection leaves the least capable without any support for their aspirations; and the almost exclusive concentration on prerequisite academic knowledge leaves some without sufficient awareness and adaptability to cope with the demands of higher education. 相似文献

This paper reports on a fragment from an educational action research in a teacher education setting, ascertaining the possibilities of using the online environment of google.doc for initiating pre-service teachers’ discourse about the nature of inclusive relationships between individuals and the environment, and the ways of their enhancement. The method of discourse analysis applied to the generated data demonstrates contradictory evidence as regards the effectiveness of the chosen medium for discourse in terms of the participants’ involvement. However, content analysis of the generated discourse yields a system of 15 approaches that pre-service teachers use for communicating about the nature of and prerequisites for inclusive relationships as well as for contemplating the role of education in enhancing them. We suggest that teacher educators can apply these approaches as a framework for exploring the frames of reference that future teachers use in making sense of the phenomenon of inclusion. The identified approaches can help to identify the paths to be pursued to develop these frames, on the grounds of an assumption that a balance can be found between the cognitive, affective, experiential and action orientations. 相似文献

Participation in elite sport, and in particular those sports with special demands in terms of weight and shape, is associated with a higher risk for eating disorders such as anorexia nervosa [Sundgot-Borgen, J., & Torstveit, M. K. (2010). Aspects of disordered eating continuum in elite high intensity sports. Scandinavian Journal of Medicine and Science in Sports, 20, 112–121]. We report upon research exploring eating attitudes and behaviours within elite gymnastics. The study comprised 42 semi-structured interviews with gymnasts and support staff—34 gymnasts and 9 staff/support staff. The majority of those interviewed were acrobatic gymnasts (22; 16 males and 6 females) with 7 rhythmic gymnasts (all female) and 5 tumblers (all female). The mean age of those gymnasts interviewed was 17.4. A difficulty in precisely delineating extreme eating patterns (disordered eating) from having an eating disorder was noted. Within an elite sports context behaviours thought to be pathological in a more general setting might be fairly commonplace and even functional to the athlete's performance. The extent to which the athlete consents to these patterns of behaviour is problematic given their age and development. We argue that conceptualising consent as ‘authority to be cared for by a trustworthy coach’, more felicitously applies to the child/adolescent elite sporting context, helping us understand not only the focus of the elite gymnast, but also their relationship with the coach and the coaches' responsibilities. 相似文献

It is widely maintained that sport and physical activities contribute to the development of young people's well-being. Others argue that sports’ contribution to good living is so strong that it is even thought to be a human right. Typically, however, the value of physical activity and sport to our well-being is conceptualized and researched within a subjectivist framework. We reject this framework on three grounds: (1) its impermanence; (2) its hedonistic shallowness; and (3) its epistemological inadequacy. In contrast, we argue that the value of sports and physical activities ought to be situated in fundamental arguments about the necessary conditions for human flourishing. According to this objectivist view, there are certain constituents of a good life without which human flourishing becomes impossible. We argue that sports and physical activities offer distinctive ways to help realize these objective constituents. It follows that, to the extent to which certain sections of society are deprived of opportunities to engage in sport and physical activity, or are offered diminished provision thereof, they thereby suffer a deficit in well-being. 相似文献

Abstract In recent academic discussions about the nature of sport, education and society much has been made of the differing ways of conceiving social relations between individualists and communitarians. I explore some of the theoretical presuppositions of methodological individualism and show how it operates in game and rational choice theory. I set out, in contrast, three related versions of communitarianism. I show how these stances differently interpret the social relation/virtue that is known as ‘trust’ and, in so doing, highlight the inadequacy of the ontological account of the self in individualistic terms and point to the necessity of viewing close interpersonal relations as ones of partially shared identity. I develop a hypothetical example of a coach's abuse of his young swimmer to illustrate the respective richness and inadequacy of these theoretical positions while leaving open the advocacy of particular political policies designed to eradicate such practices. 相似文献
