Teachers’ work-related well-being in times of covid-19: the effects of technostress and distance learning
2022
Following the outbreak of the COVID-19 pandemic, one of the first measures implemented in Italy was the transition from frontal teaching to e-learning. The sudden need to use technologies to perform their job has added a source of stress to teachers’ work, the so-called technostress. The difficulties experienced in this transition may also have affected the perception of work-related well-being, although other variables, such as the perception of the meaningfulness of work, could alleviate this sense of uneasiness. The study aims to examine the relationships between technostress, distance learning, pleasure in working and meaningful work perceptions among 219 teachers from different school …
Injury and Throwing Distance in Teenage Cyclist- Vehicle Crash
2016
The study of the injury caused by vehicle-teenage cyclist crash is presented in this paper. The results of the crash with three vehicles: sedan, SUV and Pick up are compared. Three different positions are analyzed: front, rear and lateral position. The injury on the cyclist head is examined by HIC criterion, in the way indicated by the rules. A comparison is done between the results of the simulations for Pick up, SUV and sedan, concluding that the injury of the head is more dangerous for Pick-up impact than SUV or the sedan, but only at greater speed than 40 km/h. Teenage cyclist is more likely to suffer an injury to the chest in rear impacts with the sedan, because 3 ms values remain abov…
Challenges and Opportunities of English Grammar Acquisition by Distance at the Tertiary Level
2021
Distance learning introduced in almost all educational establishments in spring 2020 has raised interest among researchers how to deal with it in a more productive way. Thus, the goal of the research was to find out undergraduates’ views on distance learning of English grammar and the use of online revision materials in developing students’ independent study skills at a tertiary institution in Latvia. the research tool was a questionnaire consisting of open-ended and closed questions. Twenty-three students answered the survey questions. the research results indicate that studying by distance is preferred because it allows the students to choose the study time and place, to develop their tim…
Problem Transformation Methods with Distance-Based Learning for Multi-Target Regression
2020
Multi-target regression is a special subset of supervised machine learning problems. Problem transformation methods are used in the field to improve the performance of basic methods. The purpose of this article is to test the use of recently popularized distance-based methods, the minimal learning machine (MLM) and the extreme minimal learning machine (EMLM), in problem transformation. The main advantage of the full data variants of these methods is the lack of any meta-parameter. The experimental results for the MLM and EMLM show promising potential, emphasizing the utility of the problem transformation especially with the EMLM. peerReviewed
Associations of Children’s Close Reading Distance and Time Spent Indoors with Myopia, Based on Parental Questionnaire
2022
Purpose: To study the association of parents’ reports about their children’s near work and outdoor habits with myopia in their children. Methods: Data from a questionnaire study conducted in 1983 among Finnish schoolchildren were reanalyzed. Vision screening had been performed for all the schoolchildren (n = 4961) in the 1st, 5th, and 8th grades (7-, 11-, and 15-year-olds) in an area of Central Finland. The questionnaire, including information about myopia, was returned by 4305 (86.7%) participants. Items concerned parents’ estimates of their child’s habitual reading distance, time spent indoors as compared with age peers, daily near work, outdoors time, and parents&…
Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…
Evaluación y caracterización biomecánica de los trinquetes de pelota valenciana. (Biomechanical assessment and characterization of the Valencian ball…
2012
El trinquete es la instalacion de referencia en la practica de la pelota valenciana, donde se juegan las modalidades profesionales de escala i corda y raspall. Sin embargo, no existe una normativa ni procedimientos de ensayo especificos que permitan definir las caracteristicas mecanicas que deben reunir paredes y pavimento del trinquete, para que los jugadores tengan una practica segura y optimicen su rendimiento. El objetivo de este estudio fue analizar diferentes variables mecanicas en las instalaciones de juego, determinar los procedimientos de ensayo mas adecuados y, finalmente, proponer unos valores mecanicos que definan una instalacion de calidad. Los estudios se llevaron a cabo en 10…
Promuovere le competenze strategiche e il successo accademico degli studenti universitari mediante il tutoraggio tra pari online a distanza
2021
Il 26 febbraio 2021 è stata avviata una ricerca-intervento ispirata alla teoria dell’educazione personalizzata. Attualmente, 19 studenti (17 femmine e 2 maschi) del secondo anno del corso di studi triennale in Scienze dell’Educazione attivato presso l’Università degli Studi di Palermo, stanno partecipando in qualità di peer-tutor a una iniziativa di didattica universitaria. Questa iniziativa persegue due obiettivi: promuovere l’autoefficacia percepita (GSE), la percezione delle proprie competenze strategiche (QPCS) e la prospettiva temporale (ZTPI) in un gruppo di 35 studenti che, giunti al secondo anno del medesimo corso di studi, non hanno ancora sostenuto da 1 a 6 esami tra quelli previs…
Comparison of impact characteristics of different ice hockey arena dasher boards
2012
During last years the incidence and severity of ice hockey related concussions have been increased and, hence, something should be done to stop this growth. The main aim of this study was to find out how dasher board materials and structures affect impact characteristics and, thereby, the risk of concussions. The measurements were divided into two parts; in the first part, the physiological characteristics of body checks were determined in real game measurements, and the second part, consisted of simulation of body checks in the laboratory. High speed cameras and accelerometers were used to collect data. More flexible protective shielding material (dasher board B) resulted in lower peak for…
