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
Health status of immigrants arrived to Italian coast [Stato di salute degli immigrati approdati sulle coste italiane ]
No full textOBJECTIVE: To analyze the factors involved in access to Emergency Department (ED) of undocumented immigrants in Lampedusa according to the country of origin. DESIGN: This is a retrospective observational study, carried out on newly arrived undocumented immigrants transferred to ED. SETTING AND PARTICIPANTS: Data were collected from medical records of Lampedusa ED between January 2012 and May 2013 on 326 undocumented immigrants. MAIN OUTCOME MEASURES: The outcomes evaluated are demographics characteristics and health condition of undocumented immigrants. RESULTS: In multivariate analysis associated factors to ED visits are: other pathologies rather than traumatic diseases (OR 0.22; p <0.001), younger age (OR 0.9; p <0.001) and female sex (OR 12.49; p=0.017) for Somalis; gastroenterological diseases (OR 2.55; p=0.026) and older age (OR 1.6; p=0.004) for Eritrean; neurological disease (OR 5.33; p=0.048) and male sex (OR 5.45; p=0.032) for Tunisian. CONCLUSION: This analysis shows that undocumented immigrants cannot be considered as a single population, because they generate a diversified set of pathological conditions
The occurrence of diseases and related factors in a center for asylum seekers in italy
Full text linkIntroduction. Italy is the main recipient of asylum seekers in the European region, and Sicily is their first
point of arrival. This geographical position creates a large job for Health Authorities to identify and deal with
the health of immigrants. This study evaluates the prevalence of disease among asylum seekers, assessing
which are associated factors.
Methods. A cross-sectional study was conducted to analyse demographic and clinical data in an Acceptance
Centres for Asylum Seekers from February 2012 to May 2013. All variables that were found to be significant
on unvariable analysis for the most frequent pathologies were included in a multivariable logistic regression
model.
Results. Post-traumatic stress disorders with 17.4% and major depression with 7.3% were the most frequent
diseases. The factors associated with post-traumatic stress disorders among asylum seekers were: major
depression diagnosis (OR=2.91, p=0.004),Pakistan as a country of origin (OR=3.88, p<0.001), the largest
number of medical visits (OR=1.02, p=0.033) and refugee status (OR=1.97, p=0.036). The variables linked
with the diagnosis of major depression from the multivariable analysis were: suffering from post-traumatic
stress disorders (OR=3.83, p<0.001), Pakistan as a country of origin (OR=3.45, p=0.004) and the highest
number of visits to psychologist (OR=1.15, p<0.001).
Conclusions.The mental wellbeing of asylum seekers needs special attention, and interventions should be
done to prevent the consolidation of psychiatric morbidity. A short psychological screening after the arrival
might prove helpful here. Moreover, carefully designed longitudinal studies should be carried out when
political recommendations try to change the organization of psychological and healthcare services
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
