LA STATISTICA PER LA MISURA DELLA BELLEZZA
No full textAbstract · Statistics to measure beauty · We would like to point out an experimentation performed
in an italian school in the first year of a Professional School in Palermo (Fashion course).A
lot of ideas, such as beauty, proportionality, perfection can be found in many professional
subjects and also in basic ones (Maths, Italian language, English language, Sciences, etc.). We
tried to adapt [email protected] (E-learning basic Maths) materials and methods “L’uomo di Vitruvio”
(Bartolomei et al., 2010), to a professional school. This didactic activity, organized by the Maths
teacher, involved other three teachers and lasted for 50 hours, not taking into account the planning
and presentation to the class. The chosen methodologies were : brainstorming, problem
solving, cognitive activity, individual and group works, lab, interactive and frontal lectures. The
assessment of the experimentation provided the teachers’ evaluation (based on the products
and the acquired skills) and the students’ self-evaluation. To conclude, we would like to show
the results in learning statistics of two groups of students : the first is the group of students
following the experimentation, the second one is a group of students learning statistics without
the experimentation (Bartolomei, Giambalvo, 2015)

A way to win by playing dice ... · The paper describes a didactic activity included in the National Scientific Graduation Plan (PNLS) realized in a Scientific College of Palermo. The aims are to underline the importance of Statistics skills owned by citizen and students in Italy and to support them for a good choice of the university course. This paper describes a didactic path of 60 hours where 18 hours are dedicated to an interaction with the teacher, to improve the Statistic skills in the students
Teaching statistics in a multidisciplinary context: an experimentation in an Italian high school
Get PDFThis paper describes an experiment performed at a Vocational School in Palermo during the school year 2010-11. It was designed to teach Statistics at the Secondary level following a multidisciplinary approach. The didactic activity involved the mathematics, Italian, English language and science teachers. We adapted materials and methods from the [email protected] E-learning program, which is planned for learning basic mathematics in a middle school, in order to use it for experimentation at a professional school. The assessment of the experimentation is based on teachers’ evaluation of each student’s whole learning process. We compare the learning outcomes of students who participated in the program with others who did not
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
