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
Hospitalization for pneumonia in the Veneto Region (North-East Italy), 2004-2012
No full textPneumonia is an important cause of illness and death particularly for elderly adults. The goal of the study was estimate the trend of hospitalization of pneumonia in Veneto Region. A retrospective study, using hospital data was conducted between 2004 and 2012 in all hospitals of region (4.81 millions of inhabitants). The reasons of hospitalization for pneumonia were defined by a first-listed discharge diagnosis of pneumonia or by a first-listed discharge diagnosis of meningitidis, septicemia or empyema associated to a pneumonia diagnosis. Annual total age-specific hospitalization rates and trend were calculated and related with vccines coverage. The total cost was calculated. Overall, 110,927 discharges were selected with an annual pneumonia hospitalization rate of 256.3 per 100,000 inhabitants with peaks in children and the elderly people. The pneumonia hospitalization rate does not increase significantly in study period [AAPC: 1.3% (CI 95%: -0.5; 3.1)], in 0-4 age group the rate significantly dropped to 451.8 per 100,000 in 2012 [AAPC: -2.5% (CI 95%: -4.5; -0.5)]. In adults 80+ the trend increases not significantly [AAPC: 1.2% (CI 95%: -0.9; 3.4)]. The overall pneumonia fatality rate was 10.7%. The estimated cost for hospitalized patient was 3,090.59 Euro.This study shows that hospitalization for pneumonia had a considerable impact on the health services, especially in children and in old groups and the availability of a new generation of conjugate pneumococcal vaccines with an enlarged antigenic spectrum and the extended indication in all ages, open new interesting opportunities to improve the control of pneumococcal disease among the entire population
Vaccination status impact on mortality and hospital re-admission for CAP in elderly: a regional italian experience
No full textThe aim of the study was to evaluate mortality and rehospitalizations after a first episode of Community Acquired Pneumonia (CAP) and to assess preliminary impact data of 13-valent pneumococcal conjugate vaccination (PCV 13) in the elderly. Preliminary analysis showed that PCV13 vaccination plays an important role in reducing re-hospitalization and mortality in elderly subjects. Long-term studies to confirm potential benefit are needed
A population database analysis to estimate the varicella vaccine effectiveness in children < 14 years in a high vaccination coverage area from 2004 to 2022
Full text linkIntroduction: In the Veneto Region of Italy, universal varicella vaccination (VV) started in 2007 with a two-dose schedule at 12-15 months and 5-6 years of age achieving 90 % coverage in 2019. The study aimed at evaluating the vaccine effectiveness (VE) in children using a primary-care database METHODS: This retrospective analysis used Pedianet, a comprehensive database of 73 family paediatricians in the Veneto Region. Incidence rates (IR) of varicella were evaluated in children aged 7 years, irrespective of their vaccination status. Indeed, the IR increased from 5.5 to 19.5 × 1000 person-years and from 1.1 to 5.4 × 1000 person-years in unvaccinated and vaccinated children aged <12 months versus those aged 5-6 years, respectively. Varicella VE was 83.4 % and 94.7 % in those vaccinated with one and two doses. After six years, the cumulative probability of experiencing varicella was 10.7 % for unvaccinated subjects, and 2.5 % and 0.4 % for those vaccinated with one and two-doses (log-rank test, p < 0.001). Conclusions: Two-dose schedule VV is effective in drastically reduce varicella episodes. Breakthrough varicella episodes remain rare events
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
