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
Life experiences and coping strategies in adults with congenital heart disease
No full textMany adults with congenital heart disease (ACHD) have to face considerable psychosocial difficulties. The aim of this study was to explore the life experiences of ACHD patients, from when they become aware of having a condition, till after the open heart surgery they underwent. The study was conducted with the use of unstructured, in-depth interviews, performed on 11 patients (age ranging: 20 - 56 y) after they recovered from open heart surgery and a focus group, which included 16 participants (age ranging: 22 - 46 y). Both the interviews and the focus group were recorded, transcribed and analyzed according to Grounded Theory procedures. Our findings show that the condition of diversity is the core of the emotional experiences connected to ACHD. Feeling different and being perceived as being different are clearly interlinked and coping strategies adopted resulted as being influenced by this perception. This study also clearly outlines the importance of having an adequate perception of one's condition and the link between maladaptive coping strategies and an incorrect perception of one's heart condition. Results are discussed in order to promote psychosocial interventions within and outside of the hospital setting in order to improve the patients' emotional wellbeing
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
Establishment of a cardiac biobank in a Department of Pathology and Laboratory Medicine
No full textBiobanks are considered to be important resources of Departments of Pathology and Laboratory Medicine allowing the clarification of relevant disease mechanisms and the improvement of the diagnosis, prognosis, and treatment of both pediatric and adult cardiovascular diseases. To successfully establish a cardiovascular biobank, it is important to consider the public opinion and views on it and the factors involved in the willingness of the public to participate in the donation of genetic material. The literature was systematically reviewed to identify the attitude and willingness of patients affected by congenital and acquired heart disease to participate in biobanking research. Six relevant studies were identified in which it was indicated that psychosocial and demographic characteristics, as well as the patient's medical condition, could influence patient and family members' attitudes and willingness to participate in research. In both congenital and acquired heart diseases, participation in biobank research activities was higher if patients and their families were approached when hospitalized, but not during the acute moment of their illness. Other quantitative and qualitative studies are required to improve patient and family participation in these research initiatives
