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
Quando nella visita si parla d’altro: un’analisi qualitativa tematica nelle consultazioni con pazienti HIV positivi
No full textIntroduzione. La crescente attenzione posta dalla letteratura negli ultimi decenni agli aspetti comunicativo-relazionali della visita medica ha messo in evidenza una consistente presenza – accanto ai contenuti legati alla malattia e all’agenda del paziente – di comunicazioni “altre”, ovvero interventi da parte del medico o del paziente legati ad aspetti sociali, relazionali e personali. Obiettivo dello studio è quello di analizzare il contenuto, la frequenza e chi tra medico e paziente introduca conversazioni “altre” all’interno di visite infettivologiche di controllo con pazienti HIV+ e valutare la soddisfazione dei pazienti al termine della visita. Metodi. Sono state videoregistrate e trascritte 52 visite presso gli ambulatori di Malattie Infettive di un ospedale del Nord Italia. Al termine delle visite ai pazienti è stato somministrato un questionario di soddisfazione. Dalle visite sono state estrapolate le conversazioni “altre”, analizzate qualitativamente con un’analisi tematica dei contenuti e quantitativamente con analisi descrittive. Risultati. Sono state identificate le seguenti aree tematiche: problema medico del paziente non inerente all’HIV; problema medico di un familiare o altri; questioni lavorative del paziente; questioni relazionali/sentimentali del paziente; questioni relazionali/lavorative di altri; conversazioni sociali; self-disclosure del medico. Le conversazioni “altre” rappresentavano il 26,5% del tempo della visita e nel 63% dei casi erano introdotte dai medici. Il 91,4% dei pazienti si è mostrato altamente soddisfatto. Conclusioni. La presenza di conversazioni “altre” nella visita medico paziente HIV+ sembra avere un valore relazionale di consolidamento dell’alleanza terapeutica e sembra rispecchiare un interessamento da parte dell’infettivologo al paziente come persona.Introduction. In recent decades the literature has paid growing attention to the communicative and relational aspects of the medical consultation, showing a consistent presence – besides contents related to the disease and the patient’s agenda – of friendly conversations or “chitchat”, i.e. interventions related to social, relational and personal aspects made by the physician or by the patient. The aim of the study is to analyze the content, frequency and who between the doctor and the patient introduce the “chitchat” during the check-up visits with HIV+ patients and assess the patient satisfaction at the end of the visit. Methods. 52 visits at the clinic of Infectious Diseases in a hospital in Northern Italy were videotaped and transcribed. All patients filled out a satisfaction questionnaire at the end of the visit. The friendly conversations were extrapolated, and analyzed qualitatively with a content thematic analysis, and quantitatively using descriptive statistics. Results. The following thematic areas were identified: patient’s medical issue not related to HIV; medical condition of a family member or others; labour issues of the patient; patient’s relational/emotional issues; relational/working issues work of others; social conversations; physician’s self-disclosure. “Chitchat” accounted for 26.5% of the time of the visit and in 63% of cases was introduced by doctors. The 91.4% of the patients was highly satisfied. Conclusions. The presence of friendly conversations during the doctor-patient exchanges in the field of HIV infection seems to have a role of consolidation of the therapeutic relationship and seems to reflect an authentic interest of the physician towards the patient as a person
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
Body habitus alterations in HIV-infected women treated with combined antiretroviral therapy
No full textFat distribution alterations are among the most frequent and unexpected side effects of combined antiretroviral therapy. They may occur in patients receiving protease inhibitor-containing regimens and those treated with combinations of only nucleoside reverse transcriptase inhibitors. The broad spectrum of body fat alterations, which are variably associated with metabolic abnormalities, raises the question as to whether they represent different components of the same syndrome or are manifestations of different pathogenetic mechanisms. Recent clinical evidence is consistent with a higher risk of developing body fat alterations in females. We here report three different aspects of body habitus changes in women treated with various antiretroviral regimens and describe their short-term follow-up. We also discuss the possible pathogenetic implications and the role of different drug classes according to present knowledg
