La gestione efficiente del materiale ospedaliero: il Just-In-Time ed il Kanban
No full textIl Settore Ospedaliero è stato ed è tuttora in continua trasformazione dal punto di vista della gestione delle risorse ad esso dedicate. L’evoluzione della politica italiana in tema di Sanità ha subito un grosso impulso con il D.Lgs. 502 del dicembre ’92 che ha portato alla cosiddetta aziendalizzazione degli Ospedali pubblici costringendo i gruppi dirigenti delle Aziende Ospedaliere a prestare maggiore attenzione alle modalità d’impiego delle proprie risorse. Gli investimenti in materiali di consumo e la loro gestione pesano notevolmente sul bilancio aziendale e da questa osservazione è nata l’esigenza di implementare nuovi sistemi di gestione delle scorte.
In tale contesto si inserisce la sperimentazione che questo lavoro vuole presentare: la ricerca che viene proposta riguarda la progettazione e la sperimentazione di un innovativo modello di riapprovvigionamento automatico di prodotti nei reparti ospedalieri basato sulla logica Just in Time. La prototipazione è stata sviluppata in alcuni reparti dell’Azienda Ospedaliera di Padova rappresentativi per le varie categorie e significativi per tipo di attività e mole di consumi. I risultati ottenuti sono eccellenti, in quanto, a fronte di modesti investimenti limitati all'introduzione di un sistema di armadi modulari e di carrelli "intelligenti", sono diminuiti sensibilmente la varietà ed i volumi di prodotti mantenuti in reparto, le quantità di farmaci scaduti, gli errori nelle ordinazioni ed i prelievi ingiustificati. Infine, si assiste da parte del personale ospedaliero, ad un importante alleggerimento delle attività amministrative di reparto, a favore dell’attività di assistenza ai pazienti
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
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

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
