No full textNegli ultimi anni è in continuo aumento il numero degli sportivi che si reca ad altitudini anche elevate, sia per la pratica dei tradizionali sport montani quali sci, alpinismo, trekking, sia per la nascita di nuove attività sportive quali mountain-bike, parapendio o skyrunning, sia per effettuare uno specifico training ipobarico/ ipossico. È quindi sempre più frequente che il cardiologo clinico, soprattutto se dedicato alla cardiologia dello sport, si trovi impegnato a valutare atleti che praticano attività sportiva in altitudin
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
Internal medicine and emergency admissions: from a national hospital discharge records (SDO) study to a regional analysis
Full text linkIn Italy, the number of internists has grown by 10% since 1990 reaching 11,435 units, they manage 39,000 beds in 1060 Internal Medicine (IM) wards. The Internists are expected to ensure a cost-effective management of poly-pathological and complex patients. A collaborative study between the Federation of Associations of Hospital Doctors on Internal Medicine (FADOI) and the Consortium for Applied Health Economics Research (C.R.E.A. Sanità) based on data from hospital discharge records has been conducted starting from November 2014. In this article the preliminary results are shown with focus on emergency admissions characteristics to contribute to define the role of hospital IM. Evaluation is performed comparing emergency and planned admissions, IM impact on hospital admissions, availability of community-based healthcare services, diagnosis-related groups (DRGs) weight in IM and regional differences in managing hospital admissions with focus on IM department. In 2013 IM wards discharged 1,073,526 patients (16.18% of the total discharged by hospitals) with a total economic value of 3,426,279.88 € (average DRG 3882.80 €, from 3682.19 to 4083.42). The average length of stay (LOS) in IM was 9.3 days. IM covers 27% of admissions from Emergency Room. Determinants significantly affecting the emergency admissions are old age and comorbidities of the patients that also have a role in increasing LOS. 55% of Italian hospital admissions are emergency admissions. Hospitalization rates in emergency are systematically higher than those in election and the greatest differences are in the regions with inefficiently organized regional network. The role of the hospital IM appears central in the offer of beds to the emergency room by accepting 27% of urgent admissions. The increasing impact of IM on hospital management will put the internists as authoritative stakeholders in health policy
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
