L'esperimento più bello della fisica
No full textIl 28 novembre 2009 si è svolto un evento di presentazione del sito web (http://l-esperimento-piu-bello-della-fisica.bo.imm.cnr.it/) dedicato all'esperimento di interferenza del singolo elettrone scelto, nel 2002, da un sondaggio di "Physics World" come l’esperimento più bello.
L'evento è stato organizzato dal Dipartimento di Fisica dell'Università di Bologna, dall'Istituto CNR-IMM di Bologna e da Unibo Cultura, nell’ambito delle attività di Scienzagiovane (http://www.scienzagiovane.unibo.it/esperimento-piu-bello.html), che ne ha anche curato lo streaming.

The Design of an Innovative Scientific Interdisciplinary Lab for Pre-Service Primary Teachers
No full textTeaching science is a crucial issue in early childhood and primary school, as it greatly influences the future attitude of pupils (and, thus, of future citizens) towards scientific knowledge. However, an effective training in teaching science cannot rely solely on isolated, well-curated courses. In this paper, we describe a widescale proposal of innovation for the academic scientific curriculum of pre-service pre-primary and primary teachers. Our aim is to
improve scientific knowledge of students, as well as their related teaching skills. The major foci of our proposal are: (i) making a “scientific environment” available, i.e. a term fully devoted to science during the five years of the academic curriculum; (ii) planning interdisciplinary lab classes connected to a central topic of keynote importance (which was
chosen to be water); (iii) allowing students to actively work on the topic through hands-on activities. The combination of these factors is expected to circumvent many flaws in the traditional academic teaching of science, which are exaggerated in the context of the education of pre-service teachers, who actually did not select a scientific course for their academic career. In a nutshell, a stimulating scientific context and more engaging, cutting-edge classes will hopefully turn motivated students into effective teachers of tomorrow
Forms of Productive Complexity as Criteria for Educational Reconstruction: The Design of a Teaching Proposal on Thermodynamics
Full text linkThe paper discusses teaching materials on thermodynamics, designed and implemented in 5 classes of scientifically-oriented
secondary schools in Italy (grade 12).
The materials are designed to: i) foster conceptual understanding; ii) create a learning environment rich enough to enable each
student to find a personal way for appropriating content knowledge.
In order to achieve the first aim, the design takes into account the main results of literature about students’ difficulties in
thermodynamics. In order to achieve the second aim, forms of “productive complexities” are implemented.
The paper presents the design criteria and shows why they have the potential to create an inclusive and creative learning
environment
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
