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
Antimicrobial Resistance in Common Respiratory Pathogens of Chronic Bronchiectasis Patients: A Literature Review
Full text linkNon-cystic fibrosis bronchiectasis is a chronic disorder in which immune system dysregulation
and impaired airway clearance cause mucus accumulation and consequent increased susceptibility to
lung infections. The presence of pathogens in the lower respiratory tract causes a vicious circle resulting
in impaired mucociliary function, bronchial inflammation, and progressive lung injury. In current
guidelines, antibiotic therapy has a key role in bronchiectasis management to treat acute exacerbations
and chronic infection and to eradicate bacterial colonization. Contrastingly, antimicrobial resistance,
with the risk of multidrug-resistant pathogen development, causes nowadays great concern. The aim of
this literature review was to assess the role of antibiotic therapy in bronchiectasis patient management
and possible concerns regarding antimicrobial resistance based on current evidence. The authors of this
review stress the need to expand research regarding bronchiectasis with the aim to assess measures to
reduce the rate of antimicrobial resistance worldwide
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
