Automatic detection of source code plagiarism is an important research field for both the commercial software industry and within the research community. Existing methods of plagiarism detection primarily involve exhaustive pairwise document comparison, which does not scale well for large software collections. To achieve scalability, we approach the problem from an information retrieval (IR) perspective. We retrieve a ranked list of candidate documents in response to a pseudo-query representation constructed from each source code document in the collection. The challenge in source code document retrieval is that the standard bag-of-words (BoW) representation model for such documents is likely to result in many false positives being retrieved, because of the use of identical programming language specific constructs and keywords. To address this problem, we make use of an abstract syntax tree (AST) representation of the source code documents. While the IR approach is efficient, it is essentially unsupervised in nature. To further improve its effectiveness, we apply a supervised classifier (pre-trained with features extracted from sample plagiarized source code pairs) on the top ranked retrieved documents. We report experiments on the SOCO-2014 dataset comprising 12K Java source files with almost 1M lines of code. Our experiments confirm that the AST based approach produces significantly better retrieval effectiveness than a standard BoW representation, i.e., the AST based approach is able to identify a higher number of plagiarized source code documents at top ranks in response to a query source code document. The supervised classifier, trained on features extracted from sample plagiarized source code pairs, is shown to effectively filter and thus further improve the ranked list of retrieved candidate plagiarized documents.  相似文献

The debate over the National Curriculum for history in England and Wales, 198990: the role of the press     

Gareth Elwyn Jones 《Curriculum Journal》2013,24(3):299-322

The construction of a history curriculum for England and for Wales under the terms of the 1988 Education Reform Act occasioned more debate in the media than any other subject in the National Curriculum. The links between the content of a history syllabus and perceptions within both nations of the part this plays in moulding national spirit made this inevitable. The disparity of view between the two groups charged with devising the syllabus and the government, particularly the Prime Minister, heightened the tension. This article explores the way in which consequent political, professional and public discussion was covered in the whole range of national newspapers. It is argued that the failure of the London press to comprehend the situation in Wales reduced significantly its appreciation of the processes involved in the making of the history curriculum.  相似文献   

Lifelong Debt: Rates of Return to Mature Study   总被引：2，自引：0，他引：2  

Muriel Egerton  & Gareth Parry 《Higher Education Quarterly》2001,55(1):04-27

High rates of return to first degrees have been used to justify increased student financial contributions to higher education. However, no discrete study of rates of return to mature graduates has been carried out although mature graduates now form a significant proportion of the student population. The General Household Survey 1983–1992 was used to examine the earnings of mature graduates compared with those of matriculates. The GHS yielded 616 mature graduate men in full-time work and 296 mature graduate women who were in full-time employment. It was found that the rate of return to mature male graduates was just above one per cent. With recent added costs, new male mature graduates can be forecast to make a sizeable loss on their study. Rates of return to women mature graduates were higher, between five and six per cent, and, based on these figures, the recent increased cost of mature graduate study should be covered by increased earnings. However, these calculations are based on average earnings for the modal age cohort of mature graduates. Those who are older when they complete or earn below the average (a large percentage) will not recoup the costs of study.  相似文献

Allied healthcare undergraduate education: international students at the clinical interface     

Gareth Morgan 《Journal of Further & Higher Education》2017,41(3):286-300

The global movement of students in higher education is a relatively recent phenomenon, which has gained momentum in the last 30 years. Much research has been focused on the experiences of this population. Relatively little is known about international allied healthcare students who undertake clinical placements as part of their undergraduate course. This study explores students’ perceptions of their clinical experience. The chosen focus group method was prefaced by a pilot study; both were conducted within the allied healthcare school of a university in the UK. Four themes emerged from the study: communication, cultural differences, relationships with professionals and survival strategies. Communication referred to both the interaction with and between the students, their patients and fellow members of the multidisciplinary team. Cultural differences were expressed in the negotiation of differing cultures at the patient interface. A third theme was the students’ relationship with clinical professionals; within this, the relationship with the student’s clinical educator was paramount. Finally, survival strategies represented the advice students wished to impart to future international students to facilitate their clinical placement abroad.  相似文献
