Learning by playing
No full textPlay plays a key role in the development of all human beings; it is a fundamental tool for stimulating the development
of thinking, language and the ability to interact with others and with the environment [1, 2, 3, 4] . Many authors in the
field of psychology have emphasized the positive values of play [5], particularly linking it to learning processes and the
experience of well-being [6]. Indeed, play occurs in a context that is "outside of reality", where the risk of failure is not
perceived as an error, but rather as one of the possibilities that play offers. This quality of play leads to a reformulation,
a loss of interest, or a shift of attention to another activity [1].
Based on these considerations, play is a core theme within the Educational Psychology curriculum in primary education
and it is a topic that needs to be experienced to be fully understood. A hands-on approach along with small group
interactions are essential, aiming to break down the anonymity of the “large class group” [6, 7]. Being able to
experiment play activities may foreshadow the vision of the so-called “reflective practitioner,” proposed by Schön [8] in
later years. Initially implemented in face-to-face classrooms, this model was later transposed into online experiences [9,
10, 11, 12]. It also introduced opportunities for reality-based tasks and guided reflection on lived experience [13] . This
hands-on approach marked the beginning of a culture of active and interactive teaching in psychological subjects taught
at the University of Macerata (and beyond) since the 1970s.
Keeping the interactive model in mind, the educational and psychological value of play activities was planned to be
taught using an interactive teaching-learning approach. To address these aims, a research project composed of three
studies was conducted. The first study aimed to explore the positive effects of play on personal well-being in the
academic classroom (emotional and social goals). In the second study [14], the experience shifted online, offering a
screen-to-screen play practice addressed to verify the impact of online interactive gaming on well-being. The third study
sought to promote understanding of the positive value of game formats in the teaching-learning process (cognitive goal)
and to encourage reflection on the game experience in order to design play activities for children (metacognitive and
learning transfer goals)
Acquired perforating follicuiitis in chronic renal failure: report of two cases
No full textBackground Patients wilh chronic renal failure, regardless of its cause, with/without hemodialysis/peritoncal
dialysis, showed cutaneous alterations. Two patients had a follicular hyperkeratotic papular eruption, with
clinical and histological features of perforating follicuiitis.
Method.s A dermatological examination and multiple skin biopsies were done.
Results We diagnosed acquired perforating follicuiitis in two chronic renal failure patients on hcmodialysis.
The lesions were located predominantly on the lower extremities wilh hyperkeratotic papules and small nodules.
Microscopically, the papule always affected ihc follicular structure. The follicle was widely dilated and packed
with keratotic material, necrotic debris and degenerated basophilic coarse connective fibers passing which
passed through foilicular perforations.
Conclusion Acquired perforating follicuiitis is a cutaneous manifestation in chronic renal failure.
with/without hemodialysis ireatment. that can mimic essential primary perforating follicuiitis. Transepidemial
elimination mechanisms and the distinction between primary and acquired perforating dermatoses arc discussed
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
