Participation in bowel cancer screening: a qualitative exploration of the factors influencing participation and uptake
No full textBowel cancer is major global public health problem. In the United Kingdom, it is the third most common cancer in men and women and second major cause of cancer deaths. It has been suggested that the risk of bowel cancer deaths can be reduced by 16% through regular bowel screening. However, screening uptake remains low. This research explored factors influencing participation in the NHS bowel cancer screening programme, specifically ‘the faecal occult blood test (FOBt)’ in the North East, Yorkshire and the Humber, (NEYH) regions.
Drawing on grounded theory, (GT) a qualitative research approach enabled the development of an understanding of participants’ experience of the FOBt and the processes involved in the choices they made. Twenty-six research
participants were recruited through the bowel cancer screening hub in accordance with ethical approval. Data collection was by semi-structured, face-to-face interviews. Analysis was done using grounded theory techniques of constant comparative method and theoretical sampling aided by Nvivo and mind genius software.
Awareness of the FOBt prior to screening invitation was found to be low. Knowledge of bowel cancer seemed to come mostly from past personal experience and family history. Decisions to participate in the FOBt were largely influenced by three main themes: Social contexts such as demographic, cognition and cultural issues; Knowledge and awareness; and Practicalities associated with obtaining samples for FOBt. Knowledge and awareness seemed to be a key influence in participation and pivotal to social contexts and practicalities.
Screening was viewed positively by all participants particularly in relation to health protection. Within the social contexts and practicality issues, there are
facilitators and potential barriers. The interactions of social and practical contexts tend to dissuade people from participating in the FOBt. However, knowledge and awareness seem to mediate the two in such a way as to
encourage people to participate. A tentative explanatory model called “awareness-led behaviour model” was developed and appears to have commonalities with the health belief model typically used to explain health
behaviours. This study is one of the few studies to investigate factors affecting uptake of the NHSBCSP in the NEYH. The results obtained in this study are likely to have high policy and practice importance as they represent user-focused perspectives. Recommendations and implications for further research, policy, practice and education are offered in the concluding chapter

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
