No full textL'articolo si sofferma sul contributo di Mariagrazia Bianchini (già docente nell'Università di Genova) agli studi di diritto romano con esposizione critica delle principali opere della Studiosa e del loro contenuto, prevalentemente rivolto a indagare l'esperienza giuridica del mondo tardoantico
IUSSIO E NOMINATIO NEGLI ACQUISTI DEL SERVO COMUNE. LA DISCIPLINA GIUSTINIANEA DI C. 4.27.2
No full textThe essay aims to investigate the influence exerted by jurisprudential thought on
late antique imperial legislation, with particular regard to Justinian’s one, in order to
ascertain how profoundly the techniques and logic developed by Roman jurists affected
it. Within Justinian’s normative production, I have chosen to analyse a constitution,
namely C. 4.27.2, that is particularly indicative of the role played by works and methods
of the jurists, because it provides ample evidence of the development of the relationship
between the classical legal science and the imperial legislatio
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
Comparison between algebraical and numerical solutions of the characteristic equation for ripple motion in presence of a surface film
No full textNumerical solutions of the characteristic equation for ripple motion in the presence of a surface film due to a tensioactive substance are obtained. A comparison between numerical solutions and algebraical approximate ones, obtained by several authors, is made. The role of tensioactive substances in increasing the vorticity of waves in the gravito-capillary frequency region is evidentiated by the dynamics of water under the surface. In particular the main dynamical differences between the two possible wave modes of water in such conditions (Laplace and Marangoni waves) are examined
Ocean surface films measured by interferential microwave probe
No full textMeasurements on sea surface films were conducted during five separate experimental periods in the following marine areas: the Sicilian Channel, the Gulf of Maine (spring and fall periods), Bermuda, and the Pacific Ocean West of Southern California. The measurements consisted in surface elevation sampling using an interferential microwave probe with frequency spectra evaluation. Wave spectra were performed for both clean and film-covered sea surface conditions to determine the wave attenuation ratio within the 2-20 Hz spectral range. The method is able to detect, chart and characterize sea surface films. Theoretical analyses of the results yield several viscoelastic film parameters: the modulus of elasticity, the relaxation frequency and the maximum of the damping ratio as a function of wave frequency. The analysed data are interpreted to infer film weathering effects, surface concentration of film-forming constituents, and compactness of the organic sea surface film
