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
The implications and management of septic acute kidney injury
No full textSepsis is the most common and severe cause of morbidity and mortality among critically ill patients. Multiple organ dysfunction syndrome often complicates sepsis, leading to a worse prognosis that is proportional to the severity and number of damaged organs. Acute kidney injury (AKI) also complicates sepsis, with a linear relationship between the severity of kidney damage and sepsis prognosis. The management of sepsis and septic AKI involves intensive proactive preventive measures, medical and extracorporeal treatment of established sepsis, support of failing organs and rehabilitation of the residual effects left by this devastating syndrome. Unfortunately, although some innovations in the clinical management of sepsis are now available, their beneficial effects on renal function are still uncertain. The aim of this Review is to provide an update on the current state of interventions in sepsis-related AKI. Prevention, pharmacological support and extracorporeal blood purification for septic AKI will be reviewed and discussed
Natural history of occult choroidal neovascularization: The results of a systematic review of literature
No full textVariations 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

No full textA survey on performance of heat pumps present on the Italian market
No full textIn this paper the performances of heat pumps are investigated. This analysis regards the calculation of coefficients of performance (COP) for several heat pumps available on the Italian market. Specification sheets of various heat pumps manufacturers declare performance values based on different reference (nominal) conditions. As a consequence, for the designer it is difficult to determine the heat pump that best fits each specific application. Even more, incentives aimed at heat pump spreading may require minimum performances levels rated at boundary conditions out of catalogue data.
In the first part of the study several technical data have been collected from different suppliers and a subdivision of different types of machines has been carried out and comparisons between the products have been performed. In order to calculate the performance of machines at the same boundary conditions, a FORTRAN code developed by the authors has been used
