Relationship between pathological gambling, alcoholism and drug addition.
No full textThe aim of this survey was to evaluate the distribution of pathological gamblers treated in an alcohol or drug addiction treatment program run by the Italian National Health Service providing assistance to alcohol and drug abusers in Venice (North east Italy) from September 1 to December 31, 2001. Each drug- or alcohol-dependent patient retained for treatment for at least one month was administrated an anonymous precoded questionnaire to collect personal and socio-demographic features. The South Oaks Gambling Screen (SOGS) was used to measure pathological gambling and the Symptom Checklist-90-Revised (SCL-90-R) to measure psychological distress levels and psychiatric symptoms. Among the 113 enrolled subjects we found a greater prevalence of pathological gamblers among drug users than among alcoholics and drug abusers were younger than alcoholics; moreover, there was a prevalence of single status, low schooling, and a low-medium income despite full-time occupation. Only pathological gamblers revealed a significant positive correlation with a family history of gambling and reached positive scores (>1.5) for some likely psychiatric symptoms. Abuse disorders and pathological gambling are frequently associated with multidependence personality traits. Preventing substance abuse may reduce the pathological gambling rates and better results can be obtained with educational campaigns beginning earlier in life
Vaccinazione antinfluenzale: fattori correlati alla risposta anticorpale in un gruppo di soggetti con titoli pre-vaccinali non protettivi

No full textIntroduction Traumatic brain injuries (TBI) and spinal cord injuries (SCI) are an important public health problem in developed countries. Hospital records were reviewed to ascertain the epidemiology of TBI and SCI in north-east Italy. Methods The annual TBI-SCI-associated hospitalization rates were estimated by analyzing data collected from rehabilitation units. TBI and SCI were identified according to the Centers for Disease Control and Prevention definition. Results The hospitalization rate for TBI and SCI amounted to 6.8 per 100,000 overall, rising from 6.2 in 1997 to 8.4 in 1999. The distribution according to gender emphasizes that TBI and SCI follow a bimodal pattern in males, with a peak in young people and in the elderly; among females, on the other hand, there is a monomodal pattern with a peak in very old women. Conclusion The fact that TBI and SCI regard not just the young, but also the elderly population is significant for regional programming purposes. Special efforts should be made to further reduce motor vehicle accidents involving young people and welfare programs are needed to limit the risk of falls and contain functional impairment in the elderly
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
