Bewertung der Betriebstemperatur eines thermischen "Langzeitdesinfektionsgeräts
No full textGli AA. hanno valutato la costanza della temperatura di esercizio in un nuovo tipo di asettizzatore a "ciclo lungo" servendosi di una speciale microsonda al Pt. I risultati ottenuti evidenziano tale proprietà. La correlazione dei dati trovati sperimentalmente, con quelli riportati in letteratura per altri asettizzatori, vengono analizzati al fine di stabilire una correlazione termodinamica con il processo di degradazione del polimero. Gli AA. concludono facendo notare che pur esistendo tale correlazione, questa è di natura solo qualitativa, non essendo tutt'ora stata valutata quantitativamente tale relazione
Psicosi e sostanze: problematiche cliniche e assistenziali in un campione di pazienti ricoverati in un reparto psichiatrico per acuti.
No full textOggetto: l'obiettivo del presente lavoro è quello di approfondire la correlazione tra le diverse sostanze da abuso e i quadri di psicosi. Metodo: abbiamo analizzato le cartelle cliniche dei pazienti ricoverati in un reparto di Psichiatria (SPDC 1 dell'AUSL di Modena) nell'arco di tempo di 3 anni, evidenziando tutti i casi in cui l'uso di sostanze era associato a una psicosi, che abbiamo differenziato, secondo il manuale in uso in reparto, l'ICD-9-CM, in psicosi indotte da droghe e psicosi endogene associate a uso di sostanze.Risultati: i dati ottenuti confermano quelli di altri autori (Andreason et al. 1987, Zammit et al. 2002) che evidenziano la correlazione tra cannabinoidi e psicosi e sono suggestivi circa un continuum tra le categorie diagnostiche delle psicosi indotte da sostanze e quelle endogene, apparentemente differenti ma probabilmente sottese da una comune vulnerabilità endogena. Nel nostro campione i pazienti schizofrenici che fanno uso di sostanze, sono in prevalenza consumatori di oppiacei, dato che potrebbe essere interpretato come una sorta di autoterapia, essendo gli oppiacei le sostanze con minor azione psicotomimetica. Per quanto riguarda la paranoia o delirio cronico, nel nostro campione essa è associata in modo più frequente all'alcol. In questi casi si può ipotizzare che l'alcol abbia un ruolo concausale indiretto e non organico nello sviluppo di una psicosi cronica, attraverso le modificazioni del comportamento e dello status sociale che l'uso cronico di questa sostanza induce nei pazienti. Le principali dimensioni psicopatologiche, potenzialmente presenti in tutti i casi in cui l'uso di sostanze è concomitante ad una sintomatologia psicotica, evidenziano la necessità di un contenimento terapeutico per una condizione di disinibizione comportamentale, spesso connotata dall'urgenza e dal rischio di comportamenti auto ed eteroaggressivi
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
