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
An Innovative dosimeter based on a floating Gate sensor
No full textThis work describes the development of a new method for recording radiation exposure by using a passive dosimeter based on a Floating Gate CMOS sensor.
The floating Gate sensors based on the MOS structure discharge allow the construction of compact and cost-efficient dosimeters, realized in VLSI CMOS technology, for use in integration mode in various applications, in particular in radiotherapy
Alcohol use, delinquency and victimization among juveniles in europe: Results from an international multi-centric study (ISRD-2) | Uso di alcol, delinquenza e vittimizzazione tra i giovani in Europa: Analisi preliminare dei risultati di una ricerca multicentrica internazionale (isrd-2)
No full textThe existence of a significant correlation between alcohol use and crime has long been acknowledged in the scientific literature. Moreover, alcohol use constitutes a serious public health problem. In order to ascertain the existence of significant relationships among alcohol use, victimization and delinquency among young people, and to describe the nature and characteristics of such relationships, a database was set up to record the results of the "International Self-Report Delinquency Study 2". This database was created by selecting a sample of young people (N=57,771) of both sexes, aged between 12 and 16 years, in 25 European countries. The research focused chiefly on the role of alcohol use and the various modes of alcohol consumption, and sought to analyze the influence exerted by different life situations (age, sex, lifestyle, friendships and personality traits). Alcohol consumption proved to be a very widespread phenomenon among young people, particularly among youths who commit crimes and those who are victims of crime. Moreover, it emerged that the abuse of alcohol was the consumption modality most closely associated with delinquency and victimization. A risky lifestyle, a lack of self-control, a positive attitude toward violence and an involvement in deviant youth groups are factors significantly associated with involvement in the use of alcohol. The results yielded by the present study indicate that alcohol use is strongly associated with delinquency among young people in Europe, and that so-called "binge drinking" is the consumption modality most closely associated with both offending and being offended agains
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
