Typology of obsessive-compulsive symptoms in children and adolescents with anorexia nervosa
No full textBackground: Previous studies have shown that symptoms of obsessive compulsive disorder are common in both adults and children and adolescents with anorexia nervosa. Until now, no study has explored the specific obsessive compulsive symptoms shown in children and adolescents with AN.Method: In this study we report types of symptoms displayed by young people with AN and explore similarities and differences with adults with AN and with people with OCD.Results: Common obsessions concerned contamination, aggressive and somatic concerns, and common compulsions were related to ordering/arranging, and checking.Conclusion: It is important for clinicians to be aware of the obsessions and compulsions they are most likely to encounter when working with these patients. If missed or ignored, such symptoms may interact with eating disorder symptoms and impede treatment
The effect of visuospatial, verbal and somatic tasks on the post-meal experience of hospitalised patients with eating disorders
No full textThis thesis is presented in three parts; the literature review, empirical paper and critical appraisal. The literature review considers the effectiveness and acceptability of interventions aimed at carers of people with eating disorders. Included studies described a variety of approaches to educate, and provide skills and emotional support to carers, although were generally of a poor methodological quality. Overall, the interventions led to improved carer outcomes, were considered helpful and there was some limited evidence to suggest beneficial client outcomes.
The empirical paper explores whether engaging in various tasks can help hospitalised patients with eating disorders to improve the experience of ‘feeling fat’ during the post-meal period. The tasks comprised of the game ‘Tetris’ (visuospatial), a general knowledge ‘Quiz’ (verbal) and translating ‘Braille’ (somatic), which were designed to reduce intrusive images, thoughts and bodily sensations. When compared to a control condition - ‘Sitting Quietly’, the tasks requiring activity were superior at improving negative affect and additional benefits were seen for all other indicators of the post-meal experience.
The critical appraisal discusses the rationale behind the literature review and empirical paper. Some of the methodological decisions are reviewed, such as choosing the tasks and the use of an online programme to deliver the trials. Dilemmas that arose whilst conducting the research are explored, such as recruitment difficulties, with suggestions for how the research could have been approached differently. The appraisal concludes with personal reflections developed over the course of the research process
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
Implicit attitudes towards food and the self in sub-clinical eating disorder pathology
No full textThis thesis focuses on the assessment of implicit cognition in disordered eating behaviour, and specifically on the role of implicit attitudes towards the self and food in sub-clinical levels of eating disorder (ED) pathology. Chapter I reviews key theoretical approaches to implicit cognition and an assessment of the properties of implicit attitudes. Chapter II discusses methodological approaches to implicit attitude assessment, with a focus on the Implicit Attitude Test (IAT) which was used in the empirical studies. Chapter III (Study 1) outlines research in implicit cognition in ED pathology and assesses differences in implicit self-esteem (i.e., implicit attitude towards the self) between high-pathology and low-pathology participants. While the results of the study supported the presence of a self-esteem discrepancy in the high-pathology group, the findings were insufficient to pursue further research in this area. The next three studies were focused on the role implicit food attitudes. Chapter IV (Study 2) introduces the hypothesis that implicit food attitudes and ego depletion may play a role in elevated ED pathology. However, the ego depletion procedure used was not successful and the results were therefore insufficient to either support or reject the hypothesis. Chapter V (Study 3) assessed similar questions to Study 2, but from the angle of automatic approach and avoidance towards food stimuli and dietary restraint failure. Contrary to expectations, the results suggested that it is unlikely that either ego depletion or a positive implicit attitude towards high-fat foods contributes to dietary restraint failure. Chapter VI (Study 4) was designed to clarify the findings of Study 3 and found that implicit food attitudes may change following novel goal activation or changes in behaviour. Chapter VII is a general discussion which summarises the findings, discusses the outcomes within the broader context of implicit cognition theories, and proposes directions for further study
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
