AIDS related information, attitudes and behaviours among Italian male young people
No full textIn order to evaluate the AIDS related
sources of information, knowledge, attitudes and
behaviours among male young people it was filled in
a multi-choice anonymous questionnaire by 2018
subjects, called for the first medical examination to
Italian Navy and by 1348 recruits. The data from
the latter group were used to make comparisons with
our previous survey carried out in 1988. The most
important sources of information on AIDS were mass
media and school, on sexuality friends and family.
AIDS awareness was greater among the high
educated subjects and positively influenced by mass
media and school as sources of information. In agree-
ment with these data, knowledge was better about
AIDS than about sexuality.
Risk perception was
positively influenced by the AIDS-related knowledge
for called youth and a greater intolerance towards
infected people was observed among the less
educated and the less AIDS-aware subjects. On
average 46% of the called up young men and 74%
of recruits declared to be sexually active: among
these, the mean age at the first sexual intercourse was
16, over 60% declared to have had multiple partners,
over 30% unknown partners and over 30% didn't use
condoms; 20% of called up and 38% of recruits
indicated 2 or 3 risk behaviours. Factors determining
sex-related risks were different according to the
behaviour and the considered group. These results
suggest that it is important for young people to be
well informed about sex and AIDS before the begin-
ning of sexual activity, if possible during compulsory
school
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
