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
Malnutrition, deficiency, and nutritional practice in patients with acute and chronic pancreatitis
No full textTHESIS 10346Pancreatitis is an inflammatory disease of the pancreas and it may occur in either acute or chronic form, the former being life-threatening in its most severe form, and the latter being a progressive, irreversible disease with gradual destruction of the pancreatic parenchyma and deterioration of pancreatic function. Both disease subgroups have different needs regarding nutritional intervention, as well as diverse research requirements. Owing to sizeable gaps in the literature, guidelines on the management of nutritional deficiency, exocrine/endocrine function and bone health are lacking in chronic pancreatitis. For acute pancreatitis, the research-base is more extensive however adherence to best practice is questionable

The Epidemiological, Clinical and Genetic Aspects of Chronic Pancreatitis in Ireland
No full textAbstract: The epidemiological, clinical and genetic aspects of chronic pancreatitis in Ireland - Hazel Maria N? Chonchubhair. Introduction: Chronic pancreatitis is a progressive, inflammatory, malabsorptive disease of the pancreas which considerably affects patients? well-being and quality of life. Chronic pancreatitis is a complex genetic disorder, characterised by signs and symptoms which differ between patients with similar aetiology. The associated health, social, and socioeconomic consequences of chronic pancreatitis experienced by patients necessitate frequent, recurrent access (care episodes) to both primary and secondary healthcare settings. The management of chronic pancreatitis is complex, fraught with difficulties, and a multidisciplinary approach to management is required, to manage symptoms and co-morbidities. Aim: The aims of this thesis were to examine the management of chronic pancreatitis in Ireland, to investigate the prevalence and aetiology of patients, to examine the prevalence of a known malabsorption-related complication - small bowel intestinal overgrowth, and to investigate the prevalence of common pancreatic gene mutations in patients with chronic pancreatitis. Methods: Four interrelated studies were designed. The first study utilised two surveys to examine the management of chronic pancreatitis by both hospital consultants and general practitioners (GPs). The second study evaluated the hospital-based prevalence of chronic pancreatitis in Ireland using the Hospital Inpatient Enquiry system (HIPE), a nationwide administrative database. A systematic review was conducted to identify studies reporting the prevalence of chronic pancreatitis worldwide. The third study used a case-control methodology to investigate the prevalence of small intestinal bacterial overgrowth in non-surgical chronic pancreatitis patients with pancreatic exocrine insufficiency (PEI) using glucose hydrogen breath testing (GHBT). The final study recruited patients with chronic pancreatitis of alcohol-associated and idiopathic aetiology to evaluate the presence of major pancreatic gene mutations. This study compared the findings in patients to a historic control database representative of the general population Results: The surveys examining the management of chronic pancreatitis revealed deficits in the management of chronic pancreatitis in both secondary and primary care, including lack of multidisciplinary team access, lack of access to dietetic care, and lack of knowledge and awareness of existing chronic pancreatitis management guidelines. These finding led to the development of the first primary care chronic pancreatitis guidelines for Ireland. The epidemiological study of chronic pancreatitis in Ireland found that the prevalence of chronic pancreatitis in Ireland was 11.6-13.0 per 100,000, and the accompanying systematic review found that this was consistent with the prevalence in other European countries undertaken using similar administrative database methodologies. Reports of SIBO prevalence amongst chronic pancreatitis are wide ranging. The prevalence of SIBO amongst Irish non-surgical chronic pancreatitis patients with PEI detected using glucose hydrogen breath testing was 15%, which is similar to other studies using this consensus methodology. Symptom improvement was documented in all patients following antibiotic therapy. Results from the genetic study revealed that almost 20% of patients with idiopathic and alcohol-associated chronic pancreatitis have pancreatic gene mutations. Patients with chronic pancreatitis have an almost four-fold higher risk of disease than controls. The frequency of SPINK1 N34S was present in 14% of patients which was significantly higher than controls and the odds ratio of disease in the presence of this mutation is almost 5-fold higher than the general public. Severe and mild CFTR cystic fibrosis-causing variants confer an increased risk of disease in patients when compared to controls. Conclusion: Results from these studies on the epidemiological, clinical and genetic aspects of chronic pancreatitis may be used for management protocols, service planning, policy, and resource allocation. It is hoped they will inform best practice, by contributing to the evidence-base, and ultimately improve the management of patients with chronic pancreatitis in Ireland and internationally
