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
Partecipazione ai corsi di accompagnamento alla nascita e riduzione dei tagli cesarei: uno studio preliminare
Full text linkItIl ricorso al taglio cesareo, in Italia, è cresciuto vertiginosamente negli ultimi trenta anni fino a raggiungere un’incidenza del 38,4% sul totale dei parti. La maglia nera spetta alla regione Campania con un tasso pari al 62,2%. I piani sanitari nazionali e regionali, in linea con le raccomandazioni dell’OMS, orientano verso una riduzione di tale pratica da raggiungersi anche attraverso il potenziamento dell’offerta dei corsi di accompagnamento alla nascita. Il nostro studio si propone di valutare l’incidenza di variabili socio-demografiche, ostetriche e psicologiche sul tipo di parto e verificare l’efficacia della partecipazione ad un corso di accompagnamento alla nascita multidisciplinare ed integrato, implementato nella ASL di Caserta, in Campania, nel contrastare il ricorso al taglio cesareo. Nella nostra indagine, effettuata su un campione di 219 donne, il ricorso al TC non appare giustificato da fattori clinici di rischio, in linea con le evidenze della letteratura: le variabili socio-demografiche ed ostetriche considerate non differiscono nei due gruppi di partorienti (con parto spontaneo e con parto cesareo) confermando l’eccessiva medicalizzazione dell’evento nascita che contraddistingue il nostro paese. Abbiamo, invece, riscontrato una differenza significativa tra i due gruppi di partorienti relativamente ad alcune caratteristiche psicologiche che potrebbero avere un ruolo nel determinare le scelte relative al parto. Infine, i nostri dati confermano l’efficacia della partecipazione ai corsi di accompagnamento alla nascita nel contrastare il ricorso al taglio cesareo. Nel nostro studio, la partecipazione al corso ha ridotto dell’8,0% rispetto al tasso regionale e dell’8,7% rispetto al tasso territoriale il numero di parti con taglio cesareo.EnIn the last thirty years the caesarean rate in Italy has dramatically increased; it accounts for 38,4% of the total childbirths. Campania has the highest percentage of birth by caesarean section with a rate equal to 62.2%. According to WHO recommendations, the national and regional health plans encourage to reduce this practice also by promoting courses for training to the birth. Our study aims to value the impact of socio-demographic, obstetric and psychological variables on the method of delivery and to value the efficacy of participation to multidisciplinary and integrated birth- training, implemented by the local health authority of the municipality of Caserta to contrast the resort to caesarean section. Our sample consisted in 219 pregnant women, which we followed up to the time of delivery: our data show that clinical risk factors did not justify the option for caesarean section: socio-demographic and obstetric variables did not differ in two sub-groups of new mothers (with vaginal delivery and caesarean delivery), confirming the over-medicalization of pregnancy and birth in our country. As regards some psychological features that could have a role in the choices for delivery, we found a significant difference into the two sub-groups. In the end, our data confirm the efficacy to take part in a birth-training course to limit the resort to caesarean section. This has reduced the number of caesarean deliveries by 8,0% and 8,7% compared to regional and territorial rates.FrLe recours aux césariennes en Italie est augmenté vertigineusement dans les dernières trente années jusqu’a rejoindre un taux du 38,4% sur le total des accouchements. Le taux plus haut est de la région Campania avec un taux du 62,2%. Le plans sanitaires national et de les régions, en ligne avec le recommandations de l’OMS, s’orientent vers la réduction de cette pratique. Pour obtenir ce résultat on augmenté l’offerte des cours pour la préparation à la naissance. Nous avons fait une étude dont nous proposons de valuer l’incidence des variables socio démographiques, obstétriciennes et psycologiques sur le genre d’accouchement et vérifier l’efficace de la partecipation aux cours de préparation à la naissance multidisciplinaires et intégrés qui ont etè organisés par l’Assistance territoriale de Caserta en Campania pour contraster le recours aux césariennes. Dans notre enquête, effectuée sur un échantillon de 219 femmes, le recours aux opérations césariennes apparait qui il n’est pas justifiées par des facteurs cliniques de risque pour santé de la mère et du nouveau-né, considéré aussi par la littérature scientifique: les variables socio -démographique et obstétriciennes considérées ne se différent pas dans les deux groupes de femmes qui ont accouché (avec accouchement naturel ou avec césarienne). Nous pouvons confirmer l’excessif abus d’opérations pour la naissance qui marquent notre pays. En fait, nous avons relevé une différence significative entre le deux groupes de femmes accouchées relativement à certaines traits psychologiques qui pourrait avoir un rôle dans le choix relatif au accouchement. Enfin, nos résultats confirment l’efficace des courses de préparation à la naissance pour contraster le recours aux opérations de césariennes. Avec cette étude, on a relevé que la participation des mères aux courses a réduit du 8,0% par rapport au taux régional et du 8,7% par rapport au taux territorial le numéro des accouchements avec césarienne
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
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
