An Experience of Microbiological Data Sharing
No full textObjectives: The control of infections and their resistance to antibiotics in hospitals is a matter of vital importance in the follow up of transplant patients. This project has the purpose of translating microbiological reports from an obsolete file structure to a system which could guarantee: a more correct and quick transmission of data, a system of storage which reduces the possibility of errors, a smoother manipulation, consultation and updating of data and, at least, a simple way to compute the cost of analysis, based on the costs determined by the national’s DRG.
Methods: The proposed solution is a semiautomatic interface which daily translates these data into a relational database, interprets the requests coming from external centres and produces reports. The prospective to use this tool for several centres, indicates us to choose an HL7 output for the interface.
Results: A prototype version of this program has been installed in February 2004. In this period, routine work has been recorded with an average of 6.5 samples per day with a maximum of 23 samples. Moreover, historical data from 1998 has been translated. The main source of errors in these data was due to patient identification problems with an average occurrence of 4,06% in virology section and of 4,16% in microbiological division.
Conclusions: A complete reorganization of the system would be desirable but at the moment it is not realistic because of obvious budget problems. The proposed approach, mainly the HL7 interface, seems to be a reasonable compromise
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
La presenza dei familiari in terapia intensiva riduce l’ansia dei pazienti e dei loro familiari?
No full textContesto: in Italia la maggior parte delle terapie intensive limita l’accesso ai familiari in fasce orarie più o meno ristrette, alcune non danno in alcun modo la possibilità ai familiari di entrare in contatto con i propri parenti (per ridurre al minimo l’ingresso di microbi potenzialmente patogeni), aumentando l’ansia dei parenti e dei pazienti ricoverati.
Scopo dello studio: il nostro bisogno di informazione è stato relativo alla presenza libera di un familiare di riferimento nelle terapie intensive come componente di riduzione dell’ansia del paziente e conseguente ripristino dei parametri vitali.
Risultati: uno studio pilota di Fumagalli S. (2006) fornisce informazioni sull’incremento della carica microbica in una terapia intensiva aperta e di contro non riporta incrementi di complicanze
settiche e le complicanze cardiocircolatorie sono dimezzate rispetto ai periodi in cui la terapia intensiva permetteva visite ristrette dei parenti . Lo studio di Azoulay E. (2003) osserva familiari di pazienti ed operatori addetti all’assistenza, misurando l’opinione degli esperti rispetto alle visite libere. Lo studio ha concluso che
l’88.2% dei familiari sono favorevoli alla partecipazione alle cure ma solo il 33.4% alla fine decide attivamente di partecipare.
Garrouste-Orgeas M. (2008) giunge alle stesse conclusioni del precedente, arruolando familiari di pazienti e rilevando un alto livello di ansia e depressione nei parenti (non sono state
specificate le scale di misurazione) confermando che la presenza dei familiari rimane, per scelta, limitata anche se la terapia intensiva è aperta.
Conclusioni: l’argomento è molto trattato ma non sono stati reperiti studi che trattino il problema in termini di evidenze scientifiche. Sull’argomento non vi sono evidenze consolidate, è area grigia
Variations on the Author
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
