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
Cost-effectiveness of enhancing adherence with oral bisphosphonates treatment in osteoporotic women: an empirical approach based on healthcare utilisation databases
No full textObjective: Adherence with Bisphosphonates therapy is generally low. Enhancing adherence with bisphosphonates would be effective in achieving the full benefits of therapy albeit a growth in the expenditure for supporting incremented drug use is
expected. The cost-effectiveness of enhancing adherence with oral bisphosphonates in a large
population of osteoporotic women has been assessed in the current study.
Design: Retrospective cohort study.
Setting: Healthcare utilisation databases of Lombardy Region, Italy.
Participants: A cohort of 28 558 women aged 45 years or more, resident in the Italian Region of Lombardy, who were newly treated with oral bisphosphonates during 2003–2004, was followed for
6 years after index prescription.
Outcome measures: Fracture-free survival time, healthcare cost and incremental cost-effectiveness ratio
(ICER) of enhancing adherence, that is, the additional cost that would be spent every year for gaining one
fracture-free year as a consequence of enhancing adherence at a certain level.
Results: Enhanced adherence from 33% (baseline) to 80%, increased both fracture-free survivals from 970
to 973 years and healthcare costs from €118 000 to €265 000 every 1000 woman-years, with ICER value of €53 000 (95% CI €49 000 to €58 000). ICER values
were lower for older women (€50 000; 95% CI €42 000 to €58 000) and for those suffering from at least a chronic comorbidity (€25000; 95% CI 95% CI
€7000 to €47 000).
Conclusions: Enhancing adherence with oral bisphosphonates offers important benefits in reducing the risk of fracture, although at a substantial cost

Tale sistema costituisce uno strumento di lettura e di monitoraggio importante per valutare la qualità dell’assistenza sanitaria erogata, conseguentemente, rispettando i principi della qualità totale, si è provveduto a migliorare il sistema per adattarlo ai modelli orientati al processo
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
One year of COVID-19 pandemic on patients with eating disorders, healthy sisters, and community women: evidence of psychological vulnerabilities
Full text linkPurpose: The COVID-19 pandemic has been a psychological burden worldwide, especially for individuals with eating disorders (EDs). In addition, the healthy sisters of patients with EDs are known to present specific psychological vulnerabilities. This study evaluates differences between the general population, patients with EDs, and their healthy sisters. Method: A group of 233 participants (91 patients with EDs, 57 of their healthy sisters and 85 community women) was enrolled in an online survey on general and specific psychopathology 1 year after the beginning of the COVID-19 pandemic. The survey examined associations between posttraumatic symptoms and depression, anxiety, obsessive–compulsiveness, interpersonal sensitivity, and eating-related concerns. Results: Clinically relevant scores for posttraumatic disorders were found in patients with EDs. Healthy sisters scored similarly to patients for avoidance. Regression analysis showed specific associations between interpersonal sensitivity and posttraumatic symptomatology in patients and healthy sisters, but not in community women. Conclusion: The psychological burden in patients with EDs is clinically relevant and linked to interpersonal sensitivity, obsessive–compulsiveness, and global symptom severity. Differences between patients, healthy sisters, and community women are discussed regarding vulnerability factors for EDs. Level of evidence: Level III: evidence obtained from well-designed cohort or case–control analytic studies
BRCA1/2 genes mutations, ovarian reserve and female reproductive outcomes: A systematic review of the literature
No full textIntroduction: BRCA1 and BRCA2 genes mutations seems to impact female fertility, in addition to increasing the risk of ovarian and breast cancer. Several studies had investigated this issue but data available are still controversial. In order to clarify the role of BRCA1 and BRCA2 mutations in female fertility and ovarian function we carried out a systematic review of the literature with the aim to establish a possible management's strategy of these patients. Evidence Acquisition: A review of current literature regarding BRCA mutation (BRCAm) and fertility was conducted using the PubMed tool to select remarkable articles with the keywords "BRCA1/2 gene,""BRCA1/2 mutation,""anti-Müllerian hormone,""female fertility,""ovarian reserve"and "premature ovarian failure."Evidence Synthesis: In current literature there are controversial findings about the relation between BRCA genes mutations and lifespan of female reproductive age. Several studies showed an higher risk of premature ovarian insufficiency of BRCAs mutations carriers, according to lower serum AMH level, primordial follicle count, or fewer oocyte yield after ovarian stimulation; on the other hand more recent studies reported not significant differences in serum AMH level or in reproductive outcomes between mutated and non-mutated BRCA patients. For this reason, currently there is not a strict recommendation for routine evaluation of fertility in female carriers of BRCA mutations. Nevertheless, the strong advice to complete childbearing by age 40 and then to undergo a risk-reducing salpingo-oophorectomy and the increased risk of infertility as a result of anticancer treatment in breast cancer BRCAm patients, make the issue of fertility and pregnancy planning in these women worthy of consideration. Conclusions: A dedicated counseling to discuss these issues, eventually associated with a personalized assessment of serum AMH or antral follicle count in order to have a panoramic view of ovarian reserve, may be useful in the management of these patients
