No full textNella Introduzione, scritta a quattro mani con Yasmina Yousfi López, coordinatrice
dell’intero volume, viene presentato un ampio panorama della presenza di intellettuali
repubblicani esiliati nei paesi del Cono Sur – Argentina, Cile, Uruguay - e delle
riviste che, accogliendo loro pubblicazioni, si sono arricchite e hanno abbracciato in
pieno l’eredità della Spagna Repubblicana
LE FRANÇAIS DANS L’INSTITUT DE MAINTENANCE ET DE SECURITE INDUSTRIELLE (IMSI) DE L’UNIVERSITE D’ORAN 2 (ALGERIE) : UNE ANALYSE CURRICULAIRE / FRENCH IN THE MAINTENANCE AND INDUSTRIAL SAFETY INSTITUTE (IMSI) OF THE UNIVERSITY OF ORAN 2 (ALGERIA) : A CURRICULAR ANALYSIS
No full textLe présent article représente la suite d’une publication antérieure (Yousfi et Aissa, 2022). C’est dans le cadre d’un projet de recherche universitaire que s’inscrivent les deux études. L’objet du projet est le « français en contexte scientifique et technique en Algérie ». Le cas que nous analysons est le programme de langue française destiné aux étudiants inscrits en première année à l’Institut de Maintenance et de Sécurité Industrielle de l’université d’Oran 2 (Algérie). Nous nous interrogeons sur la nature des objectifs visés à travers le contenu proposé et l’adéquation de ces objectifs aux besoins du public de la formation. Dans un premier temps, nous présentons l’établissement et les formations dispensées. Dans un second temps, nous examinons le programme prescrit par l’institution en en relevant les points pertinents et les insuffisances

2023 Chairs' Welcome
No full textWelcome to the 11th edition of the ACM Workshop on Information Hiding and Multimedia Security (IH&MMSec ‘23). This year’s workshop continues the tradition of representing one of the prime events in information hiding and multimedia security, attracting researchers and practitioners worldwide. Carrying on with the efforts of the previous edition to overcome the Pandemics and reunite the IH&MMSec community to present and discuss their work, this year’s meeting is held fully in person at the Water Tower Campus of Loyola University Chicago, located right at the heart of the Windy City. Bathed by the fresh waters of Lake Michigan, Chicago is the 3rd largest city in the USA, with a strong, multiethnic, and multicultural community. Besides fostering Science and their research during the workshop, attendees have countless opportunities for outdoor citywise activities, blessed by the beginning of the American Midwest Summer
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Analysis of a Fractional Reaction-Diffusion HBV Model with Cure of Infected Cells
No full textIn this paper, we propose a fractional reaction-diffusion model in order to better understand the mechanisms and dynamics of hepatitis B virus (HBV) infection in human body. The infection transmission is modeled by Hattaf–Yousfi functional response, and the fractional derivative is in the sense of Caputo. The global stability of the model equilibria is analyzed by means of Lyapunov functionals. Finally, numerical simulations are presented to support our analytical results
Improved InxGa1_xP/GaAs /Ge tandem solar cell using light trapping engineering and multi-objective optimization approach
No full textIn this paper, an analytical model for studying the effect of light trapping mechanism on tandem solar cell performance is developed. The proposed model considers diffraction grating morphology and antireflection coating of the InxGa1_xP/GaAs/Ge tandem solar cell. The main photovoltaic figures of merit of the InxGa1_xP/GaAs/Ge tandem solar cell are investigated. The obtained results prove the outstanding capability of the light trapping mechanism to improve device performance. An efficiency of 32.5% was obtained. A short circuit current density (JSC) of 28 mA/cm2, an open-circuit voltage (VOC) of 1.288 V, and a fill factor (FF) of 87.7% were calculated. In addition, the developed model serves as a fitness function to optimize the light trapping capability using a multi-objective particle swarm optimization (MOPSO) approach. The optimized tandem solar cell design exhibits higher performance characterized by JSC =35.3 mA/cm2, VOC = 1.305 V, and a conversion efficiency of 41.7% which outweighs that of the conventional planar solar cell. Therefore, the proposed design methodology efficiently minimize the reflectance via establishing an intensive light trapping mechanism at the front of both subcells and opens promising opportunities to enhance the tandem solar cell performances
