Investigating sentence weighting components for automatic summarisation
Full text linkThe work described here initially formed part of a triangulation exercise to establish the effectiveness of the Query Term Order algorithm. The methodology produced subsequently proved to be a reliable indicator of quality for summarising English web documents. We utilised the human summaries from the Document Understanding Conference data, and generated queries automatically for testing the QTO algorithm. Six sentence weighting schemes that made use of Query Term Frequency and QTO were constructed to produce system summaries, and this paper explains the process of combining and balancing the weighting components. We also examined the five automatically generated query terms in their different permutations to check if the automatic generation of query terms resulting bias. The summaries produced were evaluated by the ROUGE-1 metric, and the results showed that using QTO in a weighting combination resulted in the best performance. We also found that using a combination of more weighting components always produced improved performance compared to any single weighting component
Employing Bourdieu’s notion of habitus and capital to Investigate the international student experience within the field of higher education
No full textThis thesis explored the interplay of capital and habitus during the acculturation process of international students whilst studying in HE institutions in one geographical area. It examined how they employed capital and habitus in their new multicultural context to determine whether they were passive recipients or active participants in the field of UK Higher Education. It sought to question the culturally diverse learners’ experiences with respect to their studying and living conditions in the UK; how personal and situational variables affected their early adjustment processes; how they adjusted to the classroom and university experience, and to life in the local community. The purpose of the thesis is to build theory in relation to how international students immerse themselves in new contexts and to use this theory to support or challenge current educational discourses in the area of intercultural competency in Higher Education.
The research was carried out across three Higher Education institutions which were located in one geographical area. It uses data generated from semi-structured interviews with thirty students enrolled in the Business Administration, Applied Science and Engineering, and Medical and Health schools which have the highest enrolments of international students.
Bourdieu’s notions of habitus and capital were used as a novel lens through which to view the international student experience. Interpretivist hermeneutics were used in the analysis of the data. The main finding is that capital and habitus does lead to international student inclusion or exclusion within Higher Education provision. The findings indicate that the international students’ did actively use their capital and habitus to realise their goals in spite of barriers imposed by social and cultural reproduction. The new dispositions are as a result of developing capitals and habitus that is distinctive to each individual. There is often a dissonance between the primary and secondary habitus embodied in the individual, which leads to new identities and agency. The international students’ utilise strategic agency to develop their capital and habitus. This confirms capital and habitus leads to active participation in the international student experience.
The findings suggests further investigation of current international education policy and practice as currently international students are not contributing towards the internationalisation of universities, rather it is the international students who are becoming internationally competent and diversity is being contained. Dialogue to promote intercultural understanding between international students and home-based students is not widely occurring. This suggests that opportunities to develop intercultural competencies are not being fully accommodated or recognised with current Higher Education policy priorities regarding internationalisation at home. In spite of marginalisation within the universities and the communities, the international students are developing comparative and international perspectives and intercultural competencies through their experiences. Educators must acknowledge and respond to the dissonance as well as the cultural and linguistic diversity of the communities they serve if they want to encourage dialogue and reciprocity to develop intercultural competencies
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
