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
COVID-19 lockdown paradox: What happens to women and minors in maltracting contexts
No full textNel 2020, a causa della pandemia dovuta al virus SARS-CoV-2, in tutto il mondo è stato attivato il lockdown, richiedendo di rimanere nelle proprie abituazioni per frenare il contagio. Se l’isolamento domestico ha rappresentato la misura più efficace per limitare la diffusione del virus, per le vittime di violenza domestica, soprattutto donne e minori, ciò ha costituito un aumento del rischio di subire violenze fisiche, sessuali, psicologiche ed assistite. Molte le ragioni all’origine di tale fenomeno: l’incertezza dell’evoluzione della patologia e la precarietà economica hanno rappresentato fattori di maggiore stress, a cui si sono aggiunti la convivenza forzata tra la vittima e il suo abusante, e l’aumentato controllo di quest’ultimo, elementi che hanno incentivato il ripetersi degli episodi di violenza. Inoltre, per le vittime è stato quasi impossibile richiedere aiuto, poiché con il lockdown non si
poteva lasciare la propria abitazione e i servizi del territorio non hanno potuto garantire una vigilanza continuativa sulle situazioni più a rischio. Infine, in accordo con la letteratura, è stato riscontrato che la maggior parte delle vittime, per il loro assetto psicologico, derivante dall’aver subito a lungo violenze di ogni tipo, ritengono di avere poco controllo sugli eventi e di non poter ricevere aiuto da parte degli altri; così per lo più hanno rinunciato a richiedere un intervento esterno per uscire dalla spirale della violenza.In the course of 2020, due to the pandemic caused by the SARS-CoV-2 virus, the lockdown was activated all over the world and people were required to remain in their homes to curb the contagion. While domestic isolation was the most effective measure to limit the spread of the virus, for victims of domestic violence, mostly women and children, this represented an increase in the risk of suffering physical, sexual, psychological and assisted violence. There are many reasons at the origin of this phenomenon: uncertainty of the evolution of the ill, the economic precariousness, forced coexistence between the victim and his abuser and the increased control of the latter. These stress factors have encouraged the repetition of the episodes of violence. Other factors complicating the situation were the almost impossibility to request help because with the lockdown it could not leave home and the local services were unable to guarantee continuous supervision of the most risk situations. Furthermore, according to the literature, most of the victims (due to their psychological structure, resulting from having suffered violence of all kinds for a long time) believe to have little control over events and they cannot receive help from others; so mostly they renounce to require external intervention to get out of the spiral of violence
The phenomenon of sexting: a review on favoring factors and conseguences in adolescent age
Full text linkThis review concerns the analysis of the factors that can predispose to the sexting behaviors in adolescence and the effects on the actors involved. Empirical contributions were identified on the basis of the PRISMA method and the inclusion criteria were: studies focused on the factors predisposing sexting behavior, or on the effects in terms of psychopathological symptoms and/or risky behaviors in the subjects involved; age of participants not exceeding 18 years; empirical contributions in which there was an adequate description of the method, participants, data analysis and results; publications in English. In the analysis of the empirical contributions, it was essential to distinguish experimental sexting, i.e. voluntary sharing of personal and sexually explicit content online, from aggravated sexting, i.e. sharing carried out as a consequence of pressure from the partner or peer group. According to this differentiation, the 30 empirical contributions selected and relating to the period 2012-2022 were analyzed. The predisposing factors are some personality traits (impulsiveness, sensation seeking), depressive symptoms, the need for popularity among peers and the presence of other risky behaviors, such as substance and/or alcohol abuse. Among the effects resulting from sexting, anxious and depressive symptoms, involvement in risky sexual behavior, becoming victims of bullying and/or cyber-bullying are identified

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
