Artefatti cognitivi per l’e-learning
No full textLe potenzialità formative assunte dalle nuove tecnologie
dell’informazione, di cui sono portavoce gli Adaptive
hypermedia learning systems (AHLSs), prevedono
l’autonomia e la flessibilità cognitiva dei soggetti. Obiettivo, questo, conseguibile con la creazione di condizioni che
favoriscono i processi di autovalutazione attraverso
l’adattamento dei contenuti didattici agli stili cognitivi degli
studenti.
In questa prospettiva, la nostra ricerca ha analizzato la
relazione tra stili cognitivi, motivazione e processi di
apprendimento in ambiente SCORM. A tal fine 102 studenti,
dopo esser stati selezionati in base al proprio stile cognitivo
individuato con un appropriato questionario, sono stati
suddivisi in due gruppi, di cui il primo, che ha lavorato in
ambiente SCORM, ha usufruito dei contenuti di
apprendimento adattati secondo gli stili cognitivi, mentre il
secondo ha seguito lezioni impostate tradizionalmente. Dai
risultati è emerso il chiaro ruolo positivo giocato
dall’adattamento dei contenuti di apprendimento allo stile
cognitivo, anche in presenza di bassa motivazione intrinseca

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
Investigating the Social Robots’ Role in Improving Children Attitudes toward Recycling. The case of PeppeRecycle
No full textIn this paper we investigate the impact of a social robot in the context of serious games in which the robot plays the role of a game opponent by challenging and, at the same time, teaching the child to correctly recycle waste materials. To this aim we performed a study in which we investigated the dimensions that are used to evaluate serious games integrated with those that are typical of the interaction with a social robot. To endow the robot with the capability to play as a game opponent in a real-world context, we implemented an image recognition module based on a Convolutional Neural Network so that the robot could detect and classify the waste material as a child would do, by seeing it. After a preliminary evaluation of the approach, we started a formal experiment in which we measured the effectiveness of game design, the robot evaluation and the evaluation of cognitive and affective elements that can form the pro-environmental attitude and then the tendency to recycling. A primary school classroom was involved in the study and, results obtained so far, are encouraging and drew promising possibilities for robotics education in changing recycling attitude for children since Pepper is positively evaluated as trustful and believable and this allowed to be concentrated on the ‘memorization’ task during the game
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
Impact Memes: PhDs Humor(e)
Full text linkThe era of User Generated Content (USG) on Social Networks has invested different areas of human experience, including one of the highest levels of education, i.e. the PhD grade. As regards the opportunity to "imitate" a virtual content, the phenomenon of Memes (Shifman, 2014) is spreading. The research has two goals: to demonstrate how the practices of signification of humor on the doctorate are modified with the "memes factory" and how artificial intelligence is able to detect a complex rhetorical strategy such as humor. To satisfy these purposes, 39 memes about the PhD were collected and, then, analyzed in two levels: the quanti-qualitative, aiming to detect the semi-automatic emotional involvement, expression of humor in “meme discourses”; the semiotic analysis of meme images to understand if it is possible to classify PhD humor. The analysis show a further function of humor mediated by communication through memes, that is the complaint against a complex and precarious career path
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
