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
Quando il Service Learning pone la ricerca educativa al servizio della formazione docente e l’innovazione didattica
No full textL’articolo vuole indagare il percorso di Service Learning promosso dall’Università di Verona (La- boratorio “LeCoSe), inserito all’interno del Corso di Studi in Scienze della Formazione Primaria, per comprendere le modalità con cui esso pro- muove nei futuri insegnanti competenze didatti- che, di ricerca e riflessive, attraverso l’attuazione di esperienze di ricerca educativa focalizzate sulla progettazione, implementazione, analisi e valutazione di interventi di innovazione didattica. A tal fine l’articolo approfondisce, a titolo esem- plificativo, il progetto di robotica educativa “Re- solving Robots”, realizzato dalla tirocinante (oggi insegnante) a partire dalle esigenze specifiche del contesto. Ne vengono quindi illustrati gli step progettuali e di intervento, l’analisi realizzata al fine di verificarne l’efficacia e la riflessione critica necessaria a comprendere se e come questa esperienza abbia contribuito al rafforzamento delle competenze professionali
Experimental Wind-Tunnel Testing of Rotor/Wake Aerodynamic Interactions on a Compound Helicopter
Full text linkNumerical Investigation of the Rotor-Rotor Aerodynamic Interaction of EVTOL Configurations by a Mid-Fidelity Approach
Full text linkExperimental-Numerical Investigation of Rotor-Rotor Aerodynamic Interactions for eVTOL Aircraft Configurations
Full text linkThe paper presents the description of a research activity aimed to the systematic study of the rotor-rotor aerodynamic interaction with application to the flight conditions typical of eVTOL aircraft. The activity considers a dual effort, experimental and numerical, to gather systematic parametric data on different types of rotor-rotor interactions. In particular, the paper describes the planning and set up of a wind tunnel campaign aimed to evaluate the effects of the aerodynamic interactions on the rotor performance and flow field for two propeller models both in side-by-side and tandem configuration. Moreover, the results of numerical simulations performed with a mid-fidelity aerodynamic code on both the planned test configurations are presented showing the main effects of the aerodynamic interactions on the performance of the propeller
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
