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
The Role of Gay-Related Stigma in HIV-Risk Behavior Among Sexual Minority Men in Europe
No full textSexual orientation stigma stems from discriminatory social contexts and may ultimately impact the behavioral health of stigmatized individuals through stress-related pathways. Sexual minority stigma is of particular concern in Europe given the diversity of social contexts on the continent and sexual minority men's rapidly increasing risk of HIV infection, especially in Central and Eastern Europe, potentially rooted in stigma. This study assesses whether stigma in the ubiquitous social contexts surrounding sexual minority men (e.g., family, workplace, government) may place them at higher risk for HIV contraction across six countries. We utilized a large cross-sectional survey sample of HIV-negative sexual minority men (N = 2087; mean age = 31.6, SD = 9.7) from six European countries to test whether those who reported sexual orientation stigma also engaged in more HIV risk-related behaviors, including condomless sex with casual partners (in the absence of PrEP) and substance use before and during sex. Regression analyses were performed in Mplus. We found that a one standard deviation increase in reported sexual orientation stigma was significantly associated with the following during the last sexual encounter: a 19% increase in odds of sex under the influence of alcohol, 27% increase in odds of sex under the influence of cannabis, 49% increase in odds of sex under the influence of illicit drugs, an 11% increase in odds of condomless sex with casual partners in the past 6 months, and a 26% increase in odds of knowing where to receive an HIV test. Sexual minority men who reported perceiving greater sexual orientation-related stigma within their ubiquitous social contexts were significantly more likely to report sexual risk and alcohol and drug use during their last sexual encounter, yet reported more knowledge of preventive services. Contextual stigma might serve as a precursor to behavioral risks of HIV infection, generating maladaptive stress responses capable of being modified through individually-focused interventions. Structural interventions are also needed to ultimately reduce stigma at its source
TreC platform. An integrated and evolving care model for patients’ empowerment and data repository
No full textIntroduction: Health care has been deeply revolutionized by the new wave of information and communication technology (ICT) development, particularly related to the electronic/personal health record (PHR). The present paper describes the original design and implementation approach followed in the Trentino Province (Italy) to promote an Integrated Care Model for patients’ empowerment and data repository, by means of an evolving Personal Health Record - PHR platform, named TreC (Trentino Citizens Clinical Record). Materials and Methods: The TreC Platform is conceived as a communication hub among different stakeholders. The core assumption of the TreC platform strategy is to consider the citizen/patient as main manager and owner of both his/her own health and his/her contacts with the health care systems. Results: Over the years, the TreC platform has represented the core pillar in the digitalization process promoted at Province level. This has been strategically embedded in the multi-faceted e-government strategy endorsed by the Province of Trento. So far (October 2018), more than 89,000 citizens within the Province of Trento are using TreC platform as a way to communicate with the health care system and access their own personal health records. Conclusions: The experience gained through the TreC platform implementation and its results are promising, supporting the idea that a PHR platform can represent a key driving factor in improving health care quality and efficiency, both from a patient and a health care staff perspective
La percezione dello stato di salute in adolescenza tra fattori individuali e contestuali: Il ruolo del capitale sociale.
Full text linkObiettivo: approfondire la relazione tra il capitale sociale del quartiere di residenza, il livello di benessere familiare, la messa in atto di comportamenti a rischio e lo stato di salute percepito in adolescenza. Disegno: il lavoro è parte di una più ampia indagine trans-nazionale, denominata “Health Behaviour in School-aged Children” (HBSC) e promossa dall’Ufficio Europeo dell’Organizzazione Mondiale della Sanità (OMS). L’indagine viene svolta attraverso un questionario, messo a punto da un gruppo di ricerca internazionale, che indaga lo stato di salute e i comportamenti ad esso legati. Setting: 107 scuole superiori selezionate casualmente dall’elenco delle scuole pubbliche e private della regione Veneto. Partecipanti: il questionario è stato compilato da un campione di 2395 studenti di seconda superiore (50,3 % maschi), di età media pari a 15,88 anni (DS = ,67). Principali misure di outcome: livello di benessere familiare, comportamenti a rischio, capitale sociale, stato di salute percepito. Risultati: i risultati della regressione logistica effettuata mettono in evidenza come bassi livelli di benessere economico familiare (Odds Ratio = 2,69 [1,80-4,02]), minori livelli di capitale sociale (Odds Ratio = 2,97 [1,87-4,74]) e una maggiore messa in atto di comportamenti a rischio (Odds Ratio = 2,23 [1,52-3,27]) siano associati ad una peggiore percezione del proprio stato di salute. Si osserva, inoltre, come le femmine (Odds Ratio = 2,57 [2,03-3,25]) percepiscano uno stato di salute peggiore rispetto ai maschi. Conclusione: La messa in atto di comportamenti a rischio, il livello di benessere familiare e il capitale sociale del quartiere di residenza rappresentano importanti fattori da considerare nelle ricerche condotte sullo stato di salute in adolescenza, oltre che nei programmi di prevenzione e di promozione del benessere tra i minori
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
