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
Lo studio della scultura romanica all’Università di Roma: il magistero di Géza de Francovich e il contributo di Lorenza Cochetti Pratesi
No full textGéza de Francovich, entrato nei ranghi dell'Ateneo romano dal 1938 e poi professore dal 1956, dettò in parte le sorti in Italia dello studio specialistico delle arti del Medioevo. Queste pagine ripercorrono gli spunti critici transitati dalla sua opera agli importanti studi di Lorenza Cochetti Pratesi sul romanico, tra Nord e Sud Italia

Temperonic Crystal: A Superlattice for Temperature Waves in Graphene
No full textCoherent control of wavelike phenomena via metamaterials is driving, ever since four decades, a technological revolution in fields ranging from electronics, photonics, to phononics. Although temperature has been historically considered as the paradigmatic example of an incoherent field, undergoing diffusive as opposed to wavelike propagation, on short space and timescales Fourier law fails and the possibility for temperature wavelike propagation sets in [1]. The ultimate goal is to devise metamaterials, addressed as temperonic metamaterials, enabling coherent control of temperature oscillations arising in the hydrodynamic heat transport regime and operating at above liquid nitrogen temperature
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
Optical wavelength dependence of photoacoustic signal of gold nanofluid
No full textThe photoacoustic (PA) effect is based on the generation of acoustic waves upon absorption of light [1]. In a nutshell, the mechanism is based on the conversion of the absorbed light into heat, yielding a temperature rise inside the sample. This results in acoustic waves generated by the thermal expansion of the heated medium (a sketch of the effect is reported in Fig. 1a )
