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
Studio correlazionale su autoefficacia regolatoria, ansia/depressione ed autostima corporea in un gruppo di adolescenti femmine.
Full text linkIntroduzione
L’autoefficacia regolatoria è la convinzione sulle proprie capacità di resistere alle pressioni del mondo esterno (Bandura, 1996). Essa protegge da esiti disadattavi internalizzanti ed esternalizzanti, nonché promuove comportamenti pro-sociali; inoltre, spesso correla positivamente con la dimensione “autostima corporea” (Caprara e Pastorelli, 1999).
Obiettivi
1. Correlare i costrutti di autoefficacia regolatoria, ansia/depressione, autostima corporea;
2. approfondire le influenze sui costrutti delle variabili età e status familiare (genitori conviventi oppure separati/divorziati).
Ipotesi
- Le convinzioni di autoefficacia regolatoria si configurano come un fattore protettivo da vissuti ansioso-depressivi e incentivano la costruzione di un’immagine corporea positiva.
- L’età e lo status familiare influenzano i costrutti di cui sopra.
Partecipanti
206 studentesse di un Liceo psico-pedagogico, età 14-20 anni (media = 16.09).
Strumenti
• “Scala di Autoefficacia Regolatoria” (Pastorelli, Caprara, Barbaranelli, Rola, Rozsa, Bandura, 2001);
• “TAD - Test dell'ansia e depressione nell'infanzia e adolescenza” (Newcomer, Barenbaum, Bryant , 2002), Scala A (Scala di autosomministrazione per l’alunno);
• “TMA - Test multidimensionale dell'autostima” (Bracken, 1993), Scala “vissuto corporeo”.
Risultati
1) Dall’analisi del T Test, la media dell’autoefficacia regolatoria (3.65) è più alta rispetto all’ansia (1.84) e alla depressione (1.67).
- Il 41% presenta un’autostima corporea bassa ed il 53% nella media.
- I coefficienti r di Pearson evidenziano che la depressione correla positivamente con l’ansia e negativamente con l’autoefficacia regolatoria e con l’autostima corporea (rispettivamente con valori di r= .58; r = - .13; r= -.28).
2) Non vi sono differenze ascrivibili alle variabili età e status familiare.
Conclusioni
Minori vissuti depressivi si associano ad una maggiore accettazione della propria immagine corporea.
Le convinzioni di autoefficacia influenzano il non manifestarsi di ansia e depressione.
L’età non si configura come fattore protettivo da ansia/depressione né incentiva l’autoefficacia regolatoria
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
