IL TRATTAMENTO DEGLI STRUMENTI NEI CENTRI DI ENDOSCOPIA DEL LAZIO
No full textAn anonymous postal questionnaire on the methods of cleaning and disinfecting endoscopy equipment in the area of Rome was mailed to 94 digestive endoscopy centres. Fourtythree units (45.7%) answered. Endoscope cleaning before disinfection is performed by all centres. Only 69.8% accomplishes brushing, and 58.2% carries out manual decontamination.
The majority of centres employes a glutaraldehyde-phenate solution (44.2%) or 2% glutaraldehyde (37.2%). The most common disinfectant time of contact is 10-19 minutes (48.9%), apart from one case, all the other units presenting longer periods. The use-life of the disinfectant is ≤7 days in 51.2% of the units and >14 days in 37.2%. Internal channels is dried by 25.6% of the units.
Only 13.9% carries out some form of sterilization procedures for biopsy forceps. The majority (86%) modifies their disinfection procedures with infectious disease patients. Written protocol is present in 62.8% of units. Quality control tests on the efficacy of the endoscopy disinfection procedures is carried out in 44.2% of the centres. Only 37.2% of centres are based in hospitals with an infection control surveillance programme.
The results show an insufficient standardization in the disinfection procedures i.e.: internal channel brushing, use of not high-level disinfectants and insufficient sterilization of biopsy forceps.
It would appear therefor necessary to promote the diffusion of the guidelines for endoscope disinfection
Controllo di un'apparecchiatura automatica per la sterilizzazione di presidi medico-chirurgici.
No full textThe Authors describe the results relative to the control of a new equipment for the sterilization of endoscopes. A series of tests has been carried out using various microrganisms to determine their resistance to sterilization. The results have demonstrated that the sterilization is obtained when the apparatus is used correctly and the endoscopes were placed in the position which makes easier the contact with the disinfectant
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
Procedure di disinfezione degli endoscopi in alcuni ospedali romani.
No full textThe Authors present the results of a survey about the procedures used for the disinfection of endoscopes carried out in 23 endoscopy centres in 7 Roman hospitals. After having illustrated the principal problems inherent in carrying out the disinfection of endoscopes and the recommendations proposed by national and international committies the research methods were described.
The study demonstrated a wide discrepancy in the procedures used in the various centres and emphasized the necessity for a standardized control of the methods and the importance of the professional preparation of the personnel
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
