Birth control knowledge among freshmen of four italian universities
Full text linkSince sexual health education (SHE) is not mandatory in Italian schools, we conducted a survey on
freshmen of four Italian university campuses in 2012 to investigate the respective level of sexual
health knowledge (SHK) in relation to birth control, with the aim to inform public health policy
makers. A convenience strategy was employed to sample 4,552 freshmen registered with various
undergraduate courses at four Italian universities: Padua university (Veneto Region); university of
Milan (Lombardy Region); university of Bergamo (Lombardy Region); university of Palermo (Sicily
Region). We investigated the level of SHK on birth control using 6 proxy indicators: (1) the average
length of a woman’s period [outcome with 3 levels: wrong (base) vs. acceptable vs. correct]; (2) the
most fertile interval within a woman’s period (binary outcome: correct vs. wrong answer); (3) the event
between the end of a period and the beginning of the next cycle (binary outcome: correct vs. wrong
answer); (4) the average survival of spermatozoa in the womb (binary outcome: correct vs. wrong
answer); (5) the concept of contraception (binary outcome: correct vs. wrong answer); (6) the efcacy
of various contraceptives to prevent unintended pregnancies (linear score: 0–17). We ftted 6 separate
models of multiple regression: multinomial for outcome 1; logistic for outcomes 2, 3, 4, 6; linear for
outcome 6. Statistical estimates were adjusted for a number of socio-demographic factors. Results
were expressed as odds ratios (OR) for the 4 multiple logistic regression models, linear coefcients
(RC) for the linear regression model and relative risk ratio (RRR) for the multinomial logistic regression
model. The level of signifcance of each risk estimate was set at 0.05. The level of SHK of freshmen
sampled was rather low, as 60% interviewees did not know the average length of a woman’s period,
the average survival of spermatozoa in the womb and the concept of contraception, whilst the most
fertile interval within a woman’s period was known only to 55% of interviewees. The mean score of
SHK on the efcacy of various contraceptive methods was only 5 (scale 0–17). Some categories of
students were consistently and signifcantly less knowledgeable on birth control at multivariable
analysis: males; students from the university of Palermo; those with vocational secondary school
education and those not in a romantic relationship at the time the survey was conducted. The results
of this survey clearly call for the introduction of SHE programs in Italian schools, as already done
in several European countries. School SHE should start as early as possible, ideally even before
secondary school. SHE should be holistic and delivered with a multiple agency coordinated approach
involving the Ministry of Health, the Ministry of Education, University and Scientifc Research (MIUR),
families, schools, public health departments, primary health care providers, pharmacists, media,
other
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

No full textDispelling 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
