Olfatto accademico vs. sensibilità naturista: stili medici a confronto
No full textA partire dalla stratificazione verticale dei linguaggi specialistici, l’articolo prenderà in esame
due esempi opposti, scelti in quanto rappresentativi l’uno della comunicazione tra esperti,
l’altro della divulgazione scientifica destinata a un pubblico più ampio. La tematica affine
(l’olfatto) consentirà di valutare le peculiarità espressive dei due testi, tramite un confronto
serrato fra lo stile iperspecialistico del primo, di stampo accademico, e i tratti quasi letterari
del secondo, che si riveleranno per taluni aspetti poco in linea con le caratteristiche generalmente
attribuite alla prosa scientifico-argomentativa. Ci si chiederà infine se questi stili
linguistici così differenti non siano in realtà riconducibili, oltre che ai destinatari, anche e
soprattutto ai diversi assunti medici che vi stanno alla base.On the basis of the vertical stratification of specialized languages, this paper will consider two
contrasting examples that represent, on one hand, communication between experts and, on
the other, scientific divulgation addressing a wider public. The similar topic dealt with (i.e.
olfactory sense) will enable us to evaluate the expressive peculiarities of the two texts through
a detailed comparison between the hyper-specialized academic style of the first, and the
almost literary traits of the other, which will turn out to be in some aspects, very dissimilar
to the features generally associated with scientific-argumentative prose. Lastly, we shall pose
the question of whether such different linguistic styles are actually attributable not only to
the targeted recipients, but also, and mostly to the different medical assumptions they are
based on.

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
Redundancy management for P2P backup
No full textWe propose a redundancy management mechanism for peer-to-peer backup applications. Since, in a backup system, data is read over the network only during restore processes caused by data loss, redundancy management targets data durability rather than attempting to make each piece of information availabile at any time. Each peer determines, in an on-line manner, an amount of redundancy sufficient to counter the effects of peer deaths, while preserving acceptable data restore times. Our experiments, based on trace-driven simulations, indicate that our mechanism can reduce the redundancy by a factor between two and three with respect to redundancy policies aiming for data availability. These results imply an according increase in storage capacity and decrease in time to complete backups, at the expense of longer times required to restore data.We believe this is a very reasonable price to pay, given the nature of the application. © 2012 IEEE
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Monitoring of Drug Release via Intra Body Communication with an Edible Pill
No full textOral drug administration provides a convenient and patient-compliant way for drug delivery, especially for chronic diseases and prolonged pharmacological treatments. However, due to the repetitiveness of such therapeutic approach, the patients are led to neglect/forget the therapy affecting the healthcare delivery. Indeed, the non-adherence to pharmacological prescriptions and the unknown amount of real-time drug release result in a non-compliant therapeutic drug level over the protracted therapies. The proposed technology will enable the monitoring of both pharmacological adherence and real-time drug release. The approach exploits a passive intrabody communication (IBC) activation in order to enable an edible pill, realized starting from food additives and food-grade materials, to monitor pharmacological adherence. Following activation, the signal is modulated by IBC coupling switching triggered by pill degradation in a gastrointestinal tract, resulting in a monitored drug release. The proof-of-concept is designed for a targeted release and monitoring of Metformin in the intestine. The system shows an in vitro limit of cumulative drug release detection of 18 μg mL−1 and a limit of real-time drug release detection of 2 μg mL−1 min−1. This platform represents the first solution to monitor passive drug release in real-time, from intake to complete absorption, enabling unique and long-sought healthcare therapy and treatment opportunity
