Innovación en la gestión educativa: un estudio empírico
2021
ABSTRACT This paper analyzes the impact of innovative education tools-in this case, based on experimental methodology-on the acquisition of theoretical knowledge among management students. The study incorporates a clear split-sample design using two equivalent, randomly created groups. One group participates in a classroom experiment designed to illustrate the concept of the Phillips Curve, while the other participated in a traditional non-experimental lesson. The experiment is implemented under a strict protocol, while results evaluation is based on the comparison of post-experiment academic performance, which guarantees full anonymity and privacy of decisions. This design analyzes the imp…
La actividad física, el uso de medios tecnológicos, el rendimiento académico y el peso en los adolescentes españoles: desde el enfoque transversal al…
2016
Esta tesis doctoral está compuesta de cuatro estudios, uno transversal y tres longitudinales. Una muestra representativa de 3.095 adolescentes españoles, de 12 a 18 años, fue encuestada en el estudio transversal. Este estudio tuvo como objetivo analizar el carácter predictivo de ciertas variables relacionadas con la salud y otras variables sociodemográficas sobre la actividad física moderada-vigorosa y el uso de medios tecnológicos de pantalla en adolescentes. Una muestra de 755 adolescentes (407 chicas y 348 chicos), con edades comprendidas entre 14 y 19 años, participó en tres estudios prospectivos de cohorte. Estos estudios longitudinales tenían como objetivo examinar los cambios en el t…
La formación profesional a distancia: nuevos alumnos, nuevos retos
2020
La implantación de la modalidad semipresencial o a distancia en ciclos formativos es relativamente novedosa, existiendo un claro aumento de su demanda en los últimos años. En la Comunidad Valenciana existen 14 ciclos formativos de la familia de sanidad y el 85,7% se ofertan en la modalidad a distancia. El objetivo de este trabajo fue determinar si existen diferencias en el perfil del estudiante y su rendimiento académico entre las modalidades a distancia y presencial. Para ello, se realizó un estudio observacional transversal comparativo basado en un análisis de frecuencias. El curso seleccionado fue primero de Emergencias sanitarias, con 82 alumnos matriculados. Como instrumentos de medida…
Building renovation, sustainability and urban regeneration
2015
The paper investigates issues related to the principles of eco-sustainability and criteria of de-sign choice to be made in respect to the characteristics of the interventions. It proposes cases of recovery and re-use sustainable in Sicily, whose choices of action were made in respect of the environment and local traditions. General directives: reduction of the energy consump-tion; use of recycled and recyclable materials;improvement of the thermo/igrometric. The programming is based not only on the control of the performance, but on an idea of global quality of the operations. The correspondence between the needs and the requirements of the organism and the norms that protect the user, it’s…
Experimental Characterization and Acoustic Correction of a Multipurpose Performance Hall: The Italian Theatre “Cavallino Bianco”
2022
This study presents the retrofit acoustic dq1esign of the Italian theatre “Cavallino Bianco”. In its historical configuration, the hall had a curved roof with a pressed-plant fiber ceiling, which was demolished and replaced with a wooden roof without a false ceiling, leading to an increase in volume and a worsening of the reverberation time. This study proposed the realization of a wave ceiling and the application of sound-absorbing and reflecting panels on the walls, which have already been implemented. These modifications have affected the acoustic characterization of the theatre, as shown both through on-site measurements during the main construction phases and through numerical simulati…

La colaboración científica: principales líneas de investigación y retos de futuro
2014
The construction of knowledge is a collaborative process that has seen a dramatic growth over recent decades, since almost all research activities now involve increasing numbers of researchers, institutions, disciplines and countries. The present study provides a bibliographic review of the literature on research collaboration and identifies pioneering work on the topic, the types of studies undertaken and the variables analyzed. Several approaches are discussed: the “classical” approach, based on bibliometric indicators, which has taken on a new dimension with Social Network Analysis; and quantitative and qualitative approaches, which attempt to investigate the motivations and dynamics of …
The dissolution of gypsum of Disueri reservoir left bank
2011
Results of a laboratory research programme on the rate of dissolution of selenitic gypsum are reported and discussed. The tested gypsum samples have been recovered from boreholes drilled in a thick layer outcropping on the left bank of Disueri reservoir located near Gela in Sicily. The tests carried out demonstrate that the rate of dissolution Rd depends essentially upon the velocity v of water flowing over the surface of the gypsum. Values of Rd range from 0.94 to 3 kg/(m2 • day) for v values from 0.05 to 0.20 m/s. Such high rates can account both for the rapid evolution of the existing cavities and for the creation of new caves within the gypsum mass subsequent to the impounding of the re…
IL RETROFIT ENERGETICO. L'EDILIZIA RESIDENZIALE POST-BELLICA DI PALERMO
2015
Il patrimonio edilizio italiano è composto principalmente da costruzioni realizzate nel secondo dopoguerra, quando la speculazione economica e l'urbanizzazione hanno prodotto edifici con caratteristiche di scarsa qualità architettonica ed energetica. Agire sul rendimento energetico degli edifici esistenti, adattandoli alle caratteristiche richieste dalla normativa, a parità di condizioni di comfort, rappresenta una strategia importante per la riduzione dei consumi energetici e per la tutela dell'ambiente. Attraverso l'applicazione di tecnologie e metodologie innovative e la scelta di investimenti adeguati, il retrofit energetico può rappresentare oggi la principale opportunità di crescita i…
Resilience between mitigation and adaptation
2020
The relation between architecture and time is the subject of two papers. The first illustrates the variations this relationship can make on the notion of resilience, applying it to architectural design and current experimentations of Design for Disassembly. The second focuses on the important subject of population ageing and on the need to study and develop forward-looking forms of a sustainable elderly-friendly living environment in Bulgaria, suggesting potential directions for future development in the context of a resilient society. Finally, the book includes an essay dealing with the importance of new digital technologies in the transition towards a resilient and sustainable city: the d…
