Carriage of Neisseria meningitidis Serogroup W135 ST-2881
Serogroup W135 ST-2881 meningococci caused a cluster of meningitis cases in Niger in 2003. Of 80 healthy persons in the patients' villages, 28 (35%) carried meningococci; 20 of 21 W135 carrier strains were ST-2881. Ten months later, 5 former carriers were still carriers of W135 ST-2881 strains. The serum bactericidal antibody activity changed according to carrier status

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Progress and policies to achieve the zero pollution action plan and EU 2024/2881 PM2.5 targets in Northern Italy
Abstract Fine particulate matter (PM2.5) is a major contributor to air pollution-related mortality in Europe. The European Zero Pollution Action Plan (ZPAP) aims to reduce PM2.5-attributable deaths by 55% by 2030 relative to 2005, while the EU Directive 2024/2881 states the new Ambient Air Quality targets. The open questions are: (1) has the ZPAP and the EU Directive 2024/2881 target for PM2.5 already been reached? If not, (2) will the current policy allow the ZPAP and EU 2024/2881 target for PM2.5 to be met in 2030, or (3) is an additional policy needed? This work proposes a methodology to estimate the attributable deaths caused by PM2.5 exposure in 2005, 2019 (question 1), and 2030 projection, considering the current legislation (CLE2030, question 2) and a policy (OPT2030, question 3), solution of a multi-objective problem that minimizes PM2.5 concentration and measure costs. The methodology was tested on the Po Valley in Northern Italy, one of the most polluted areas in Europe. Results show that premature deaths decreased by 36% on average from 2005 to 2019. By 2030, under current legislation (CLE2030), 18 of the 29 major cities are projected to meet the ZPAP target, while only 2 are expected to comply with the PM2.5 target of the Directive (EU) 2024/2881. With the implementation of additional measures (OPT2030), the number of cities meeting the ZPAP target rises to 26, and 13 are projected to achieve the PM2.5 limit recommended by the Directive (EU) 2024/2881
