Co-infection HBV and malaria: a striking association
No full textBACKGROUND: Many geographical areas are highly endemic for infectious tropical diseases, although in disproportional fashion. Various infections often overlap in terms of presentation of various epidemiological and clinical manifestations that are linked to the mutual influence of pathogens. The epidemiological and clinical aspects of hepatitis B virus and malaria co-infection remain little known because there have not been many studies until recently.METHODS: We performed a systematic search of the epidemiology of HBV/malaria co-infection, in particular, their overlapping clinical and histological features and their reciprocal conditioning. We examined published data regarding HBV and malaria.RESULTS: The data we obtained varied substantially. The interaction between malarial parasites and HBV viruses, both in chronic HBV hepatitis patients and in carriers, did not vary or change the clinical evolution of either infection. The diversity of epidemiological and clinical results depended both on the geographical areas in which the studies were carried out and on the various stages of the infections at the time of the study.CONCLUSION: Strategies to improve currently available diagnostic techniques, and studies dealing with vector control procedures and other operational tools and approaches are needed for better understanding of this health problem
Le prospettive di rilancio dell’economia della pesca siciliana nel passaggio dal FEP al FEAMP. Il ruolo delle realtà aggregative del settore e l’elaborazione di un patto per lo sviluppo sostenibile per la pesca
No full textIl capitolo contiene un esame aggiornato dello stato di avanzamento delle misure relative al fondo strutturale per la pesca nel periodo 2007-2013 (FEP) al fine di valutarne gli effetti su una possibile ripresa economica del settore. Tale analisi, in una fase di quasi completamento del FEP, viene messa in rapporto agli interventi previsti nel nuovo programma per il periodo 2014-2020 (FEAMP) allo scopo di:
a) valutare la coerenza e la continuità delle strategie dei fondi strutturali destinati al settore della pesca siciliano in rapporto all’obiettivo di arrestare il declino strutturale del settore;
b) individuare i possibili raccordi tra le politiche strutturali della vecchia e nuova programmazione al fine di elaborare un patto di sviluppo maggiormente rispondente alle esigenze manifestate dalle imprese del settore;
c) analizzare i processi di aggregazione e gli assetti cooperativi in atto a livello locale nell’ambito del FEP, nonché i possibili scenari in relazione ai nuovi indirizzi del FEAMP nella prospettiva di una maggiore efficacia degli interventi pubblici
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
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
