Preliminary evaluation of a short version questionnaire for Executive Functioning Self-Report (EF-SR)
No full textThe aim of the present study is the development and the evaluation of preliminary psychometric characteristics of a short form self-report questionnaire to assess executive functioning (EF). The research was conducted in a sample of 316 Italian children that attended primary or secondary schools, with an age range between 7 and 11. EFA showed that Executive Functioning Self-Report (EF-SR) is composed of eleven items that are adequately represented by a single factor that characterizes the total score of the EFs. Furthermore, preliminary analyses showed an adequate level of skewness and kurtosis, of internal reliabilities, and test-retest reliability. Finally, the EF-SR showed positive moderate correlation with Stroop Congruent Trials, and with the Stroop Control trials, while the correlations with the other measures were not significance (Color Word Stroop task, the Corsi Block Tapping and the Tower of London), demonstrating appropriate discriminant validity. In conclusion, the EF-SR proves to have the potential to be an easy and fast questionnaire for measuring EF, especially in children
An innovative platform to promote social media literacy in school contexts
No full textIn spite of the impressive number of adolescents using social media, only a minority is aware of the risks associated with the use of the Internet. Hate speech, violation of personal rights, psychological attacks, deceiving people with fake accounts, as well as cyberbullying, harassment and insults are some examples of toxic content that can jeopardize adolescent well-being on the Web. Social Media literacy paths in school contexts provide students with the proper defence instruments to face these problems. Furthermore, it is important to underline the role of social media on both the intrinsic and extrinsic motivation of adolescents which has short-and long-term influences when using these virtual environments. However, traditional teaching approaches are not enough to engage students, and the need for innovative learning activities and tools emerges. In this paper we present an online platform specifically designed to support the development of competences related to Information and Data Literacy, Communication and Collaboration and Digital Content Creation. These competences are connected to the most recent versions of the Digital Competence Framework for Citizens, and the Global framework of reference on digital literacy skills promoted by UNESCO. The platform is based on PixelFed, an open-source alternative to Instagram, so that adolescents can practice with an environment they are familiar with. Our platform extends the PixelFed environment with functionalities designed to implement use cases that make students aware of the mechanisms behind social media, such as the use of artificial intelligence algorithms to filter the content they have access to. This platform has been experimented during a pilot run with secondary school students, by proposing them educational activities based on our platform, aimed at educating and supporting students to increase their awareness and counteract the problems that arise within social media
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
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
