A method for evaluating the hepatitis B vaccination program
No full textTwo mathematical models have been created in order to estimate the effectiveness (number and proportion of infections saved) and the cost/effectiveness ratio (cost per infection saved) of a hepatitis B vaccination strategy among hospital personnel. The aim of the models is to analyse the mathematical relationship between the measurement of strategy impact and some variables: theoretical effectiveness of vaccine, proportion of assent to the programme, epidemiological characteristics. Applying models to Piedmont situation it has been possible to identify factors which have negatively influenced the effectiveness and efficiency of strategy
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
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
La repressione dei reati di furto e rapina nel Liber sententiarum potestatis Mediolani del 1385: acquisizioni e questioni aperte
No full textLe decisioni contenute nel Liber Sententiarum del podestà di Milano relativo all’anno 1385 (oggetto di una recente pubblicazione) sono in grado di restituirci, sia pure in forma parziale e lacunosa, un’immagine piuttosto vivida dell’amministrazione della giustizia penale nella Milano viscontea. Le sentenze, per ciò che riguarda i reati di furto e rapina qui considerati, mostrano una non frequente incidenza di tali figure criminose e nel contempo (specie per quel che riguarda il furtum) la propensione ad una decisa risposta repressiva da parte degli organi giurisdizionali comunali. L’analisi delle stesse ha permesso altresì di formulare qualche ipotesi ricostruttiva intorno alle norme all’epoca vigenti, che sembrano essere sostanzialmente osservate dai giusdicenti. Nell’ambito di un avanzato fenomeno di ‘pubblicizzazione’ della giustizia punitiva (che si percepisce soprattutto nella sfera procedurale), non mancano tuttavia di emergere alcune tracce della sopravvivenza di una dimensione ‘negoziale’ del penale che si estrinseca soprattutto nelle forme delle transazioni private intorno alla pena.The decisions contained in the Liber Sententiarum of the mayor of Milan, relating to the year 1385 and now published, give us, albeit in a partial and incomplete form, a vivid image of the administration of criminal justice in Milan during the Gian Galeazzo Visconti’s government. The sentences, as regards the crimes of theft and robbery considered here, show an infrequent incidence of such criminal figures and, at the same time (in particular as regards the furtum), the propensity for a decisive repressive response by the municipal courts. The analysis of the sentences also allowed us to formulate some reconstructive hypotheses around the rules in force at the time, which seem to be substantially respected by the judges. In the context of an advanced phenomenon of ‘publicization’ of punitive justice (which is perceived above all in the procedural sphere), there are, however, some traces of the survival of a ‘negotiated’ dimension of criminal law, which is expressed above all in the forms of private transactions around the penalty
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
