An international review on one and two level innovative unconventional intersection and interchange.
2013
The research on road intersection and interchange has recently allowed to design innovative one and two level unconventional layouts (UIIDs) which are of undoubted interest, especially in terms of traffic functionality and safety. The main objective of the paper is to discuss the geometric layouts, the principal advantages and the disadvantages, in terms of cost, safety, performances of the most interesting UIIDs, like two-level signalized intersection (TLSI), single-point urban interchanges (SPUI), center-turn overpass (CTO), echelon interchange (EI), Crossover Diamond interchanges (DCD), Upstream Signalized Crossover Intersection (USC), Median U-turn Intersection (MUT), “Target”, “Flower”…
Deconstruction and hermeneutical space as keys to understanding the rural
2020
The purpose of this article is to complement the existing literature on defining the rural by suggesting a novel approach that makes possible a holistic understanding of the rural. The proposed approach is based on deconstruction of the concept of the rural and on hermeneutical philosophy. The current approaches applied in rural studies are evaluated through the lens of holistic understanding, and solutions to the observed problems are discussed. The problems of current rural studies stem from inadequate conceptualization and biased social theory. The conceptual problems can be alleviated, firstly, by understanding the concept of space not only literally but also figuratively. Secondly, the…
Developing Students Well-Being and Engagement in Higher Education during COVID-19—A Case Study of Web-Based Learning in Finland
2023
COVID-19 rapidly and extensively changed the normal everyday practices of societies, and there is no going back to the past. Universities also had to adapt and re-establish their normal routines, from policies to practices. In this article, we explore university students’ experiences of web-based learning, their well-being, and engagement during the pandemic. As a theoretical framework, we use the concept of the university student engagement inventory (USEI), which includes behavioral, cognitive, and emotional dimensions. The data were collected during the COVID-19 pandemic from university students (N = 35) via an online survey and analyzed using a thematic content analysis. According to th…
Protective and Educational Effects of Physical Activity Practice on Mental Health in Young Age during COVID-19 Lockdown
2022
Background: The restrictions imposed by the COVID-19 pandemic have modified the lifestyle of young people, worsening their mental health. Although some countries were allowed to practice outdoor physical activity (PA) in cases of lockdown, the PA level in the general population decreased. The current study aims to assess the differences in fear of COVID-19, anxiety, neuroticism, and general self-efficacy between university students who practiced PA during the second wave of lockdown and those who did not practice any PA. Methods: The sample consisted of 276 university students (176 females, 63.8%; mean age: 22.13, SD: ±3.94) who answered an online questionnaire detecting life habits …
IEA EBC Annex83 Positive Energy Districts
2021
At a global level, the need for energy efficiency and an increased share of renewable energy sources is evident, as is the crucial role of cities due to the rapid urbanization rate. As a consequence of this, the research work related to Positive Energy Districts (PED) has accelerated in recent years. A common shared definition, as well as technological approaches or methodological issues related to PEDs are still unclear in this development and a global scientific discussion is needed. The International Energy Agency’s Energy in Buildings and Communities Programme (IEA EBC) Annex 83 is the main platform for this international scientific debate and research. This paper describes the challeng…

Multimetallic Oxynitrides Nanoparticles for a New Generation of Photocatalysts
2019
A versatile synthetic strategy for the preparation of multimetallic oxynitrides has been designed and here exemplarily discussed considering the preparation of nanoscaled zinc-gallium oxynitrides and zinc-gallium-indium oxynitrides, two important photocatalysts of new generation, which proved to be active in key energy related processes from pollutant decomposition to overall water splitting. The synthesis presented here allows the preparation of small nanoparticles (less than 20 nm in average diameter), well-defined in size and shape, yet highly crystalline and with the highest surface area reported so far (up to 80 m2 g-1 ). X-ray diffraction studies show that the final material is not a…
Dual Enzyme-Triggered Controlled Release on Capped Nanometric Silica Mesoporous Supports
2012
The development of nanoscopic hybrid materials equipped with “molecular gates” showing the ability of releasing target entrapped guests upon the application of an external trigger has attracted great attention and has been extensively explored during recent years.1 These nanodevices are composed of two subunits, namely, a suitable support and certain capping entities grafted on the surface of the scaffolding.2 The support is used as a suitable reservoir in which certain chemicals can be stored whereas the molecules grafted in the outer surface act as a “gate” and can control the release of the entrapped molecules at will. Both components are carefully selected and arranged in order to achie…
Referee efficacy in the context of Norwegian soccer referees – A meaningful construct?
2018
Abstract Objectives The purpose of this study was two-fold. Firstly, to examine the measurement/factorial validity and invariance of the Referee Self-Efficacy Scale (REFS) among Norwegian soccer referees. Secondly, extending scale validation, we also tested a structural model in which a second-order version of the REFS was modelled to mediate a set of theoretically informed antecedents and outcomes. Design Cross-sectional. Method One hundred and eleven Norwegian elite referees and 81 non-elite referees completed an electronic questionnaire measuring expected antecedents and outcomes of perceived self-efficacy in the role as referees. Results Analyses provided support for the first – and sec…
Diseño y validación de un instrumento para evaluar la colegialidad docente
2016
El estudio trata de diseñar y validar un instrumento de evaluación de la colegialidad docente, como calidad de unión entre el profesorado de los centros docentes de educación primaria de España y México. El instrumento diseñado se basa en seis dimensiones: (1) valores éticos y profesionales compartidos; (2) cohesión y confianza en el grupo, actitudes de alianza, compañerismo; (3) compromiso con la tarea docente, actitud de mejora profesional continua; (4) toma de decisiones colegial sobre la tarea docente; (5) relaciones docentes colaborativas: autonomía y colectividad en la tarea docente, respeto y constructivismo en las relaciones interpersonales; (6) Clima dinámico y positivo del centro,…
