The Projects of Guccia: First Stage
2018
The founding of the Circolo Matematico di Palermo and its journal, the Rendiconti del Circolo Matematico di Palermo are discussed. In order to understand the path that led to these two events, we follow G.B. Guccia’s post-doctoral journey in the summer of 1880 through Paris, Reims and London. Despite many initial difficulties, the early success of the society and the journal encouraged G.B. Guccia to lead the society towards internationalization.
Pornografía infantil: cambios en las formas de obtención y distribución
2017
RESUMEN: El objetivo de este estudio es sintetizar el conocimiento científico sobre los principales mecanismos empleados para la obtención y distribución de pornografía infantil a lo largo de la historia. Para ello, se ha realizado una búsqueda exhaustiva de los trabajos publicados hasta 2016, siendo seleccionados un total de 37. Los resultados obtenidos permiten diferenciar cuatro grandes etapas del tráfico de pornografía infantil (comercial, informatizada, Internet, oculta), en las que los consumidores han migrado hacia tecnologías que les resultan más atractivas y adecuadas para sus fines (Deep Web y redes p2p sin filtro). Sin embargo, un sistema descentralizado como Internet impide la a…

Online Communities and Gambling Behaviors : a Systematic Review
2022
Abstract Purpose of Review The internet and virtual environments have enabled the formation of online communities around a variety of interests. Online communities focused on gambling are increasingly popular and attract users to interact and share ideas and experiences with likeminded others. This study reviews evidence from the latest research examining the role of online communities in gambling behaviors and gambling problems. Recent Findings A systematic literature search resulted in 17 studies. Research shows that online communities are used for diverse reasons like discussing gambling experiences and problems, sharing tips, and celebrating winnings with others. These reasons of online…

Towards Successful Implementation of a Virtual Classroom for Vocational Higher Education in Indonesia
2019
The virtual classroom continues to grow, but it is becoming more and more the norm, and it is fundamentally different from the vocational students at the Indonesian university. With the promised benefits of the virtual classroom, many challenges and difficulties come in the implementation. Although there are already successful design principles for virtual classrooms that support organizations in overcoming the challenges, the approach to implementing the design principles of virtual classroom at the vocational higher education in Indonesia is still lacking. In this study, we aim to answer the research gap and used the design sciences research by interviewing the lecturers to design the sol…
Actuaciones procesales de la mujer en Roma. Prohibición edictal y literatura jurídica
2020
[Resumen] La improcedencia moral de que las mujeres usen de la palabra en el ámbito público, que se refiere a los lugares de espacio relevante como es el forum o intervengan en actos jurídicos formales, especialmente los solemnia verba, no impide que pueda intervenir procesalmente en defensa de asuntos propios y ajenos, aunque esta postulatio se traten de virilibus officiis. De esta forma la intervención de la mujer en la defensa de asuntos propios y ajenos aparece como algo poco común pero no prohibido hasta finales de la república. Un edicto de la primera mitad del s. I a. C, introduce el impedimento general de que intervenga la mujer en los procesos ajenos. La contradictoria afirmación q…
A Simulation Analysis of VSM Control for RES plants in a Small Mediterranean Island
2020
The paper presents an application of Virtual Synchronous Machine control for managing inverter-interfaced renewable energy sources in a small Mediterranean island not supplied by the main grid. In the proposed analysis, the island's renewables-based generators area assumed interfaced to the grid by voltage source converters with a swing controller and a vector-current controller with two different options for the reference current for regulating the voltage at the Point of Common Coupling and the active power output. The system, modeled in PScad environment, allows to verify the response of the renewables-based generators with VSM control in the presence of a fault in the grid.

A VR/AR Environment for Multi-User Liver Anatomy Education
2021
We present a Virtual and Augmented Reality multi-user prototype of a learning environment for liver anatomy education. Our system supports various training scenarios ranging from small learning groups to classroom-size education, where students and teachers can participate in virtual reality, augmented reality, or via desktop PCs. In an iterative development process with surgeons and teachers, a virtual organ library was created. Nineteen liver data sets were used comprising 3D surface models, 2D image data, pathology information, diagnosis and treatment decisions. These data sets can interactively be sorted and investigated individually regarding their volumetric and meta information. The …
