Il laboratorio di Zoologia in tempo di pandemia. Esperienze, soluzioni e riflessioni di un docente.
Full text linkThe work describes the adjustments made to the management of a laboratory in the presence of students, i.e., a Zoology Laboratory, in times of pandemic. We discuss the guidelines for students, which are rules designed to avoid the spread of the virus by respecting the provisions of law. The provisions include social distancing, masks, sanitation and ventilation of the environments. Students are also required to declare their state of health to access the university laboratories. For the use of the laboratory microscope in class, a new task for the teacher was to photograph and archive all the zoological preparations that were shown to students. This hindered close contact among students who observe the zoological preparations, and between students and the teacher who gave explanations in class. For outdoor activities, an equally complex organization was required, both to bring the students to the place of the outdoor activities as well to organize contacts necessary for an active involvement of outside institutions, (Foci of the Isonzo Regional Reserve, Miramare Marine Reserve, Museum of Natural History of Trieste) in order to organize group visits on their re-opening after the lockdown.
Nel contributo vengono presentati gli adeguamenti necessari, apportati alla gestione di un insegnamento di laboratorio impartito all’Università di Trieste - si tratta del Laboratorio di Zoologia per il Corso di Laurea in Scienze e Tecnologie per l’Ambiente e la Natura (STAN) - in tempo di pandemia. Si illustrano le linee guida per la fruizione del corso da parte degli studenti, le regole di comportamento atte a evitare la diffusione del virus nel rispetto delle norme di legge vigenti e si parla inoltre del distanziamento sociale, delle mascherine, nonché dell’igienizzazione e dell’areazione degli ambienti. Si evidenzia, inoltre, l’obbligo da parte degli studenti di dichiarare il proprio stato di salute per poter accedere alle aule dell’Ateneo. Per quanto riguarda il nuovo lavoro da espletare da parte del docente, esso è consistito, per la parte dedicata al laboratorio di microscopia da svolgere in aula, nel fotografare e archiviare tutti i preparati zoologici da far visionare agli studenti, in modo da evitare contatti ravvicinati per l’erogazione di singole spiegazioni durante l’osservazione degli stessi. Per la parte di campagna è stata necessaria una progettazione altrettanto complessa sia per organizzare gli spostamenti nei luoghi dell’attività, sia per intraprendere i contatti necessari per un fruttuoso coinvolgimento attivo di enti extra-universitari (Riserva regionale Foci dell’Isonzo, Riserva Marina di Miramare, Museo di Storia naturale di Trieste) per lungo tempo chiusi, al fine di poter organizzare visite di gruppo non ancora previste nella fase di post lockdown

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

No full textAppropriate 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
