Perfil del usuario de centros deportivos privados, según género, edad y nivel de antigüedad
2019
En los últimos años ha surgido una extrema necesidad de perfilar a los usuarios de instalaciones deportivas debido al crecimiento en el sector tratando de ser cada vez más competitivos adecuando la oferta a la demanda (Nuviala et al., 2014). El objetivo del presente estudio fue definir el perfil del usuario, en función de la calidad, satisfacción, valor percibido e inten- ciones futuras, analizando si éstas varían según el género, la edad y el nivel de antigüedad, en 481 socios de tres centros deportivos privados. Para ello, se les administró un cuestionario y se realizó una prueba t- para muestras independientes y un estudio de contraste grupo a grupo con la prueba t- del test de Scheffé y…
Perfil del usuario de la fundación deportiva municipal de valencia y sus hábitos de práctica deportiva
2019
El objetivo de la presente investigación es analizar el uso de las instalaciones de la Fundación Deportiva Municipal de Valencia y determi- nar el perfil del usuario de las mismas. Para ello se recogen un total de 727 cuestionarios vía online formados por diferentes secciones extraídas a partir de la bibliografía existente. Los resultados muestran una alta satisfacción e intenciones futuras de los usuarios. Además, los usuarios muestran una ma- yor pasión armoniosa por el deporte en comparación con la pasión obsesiva. La mayor parte de la práctica deportiva se concentra entre semana y a partir de las 19:00h. Los usuarios de las instalaciones en su mayoría tienen trabajo y estudios universit…
Comportamentos de suporte e eficácia grupal: o papel mediador dos comportamentos de aprendizagem
2018
Dissertação de Mestrado em Psicologia do Trabalho, das Organizações e dos Recursos Humanos apresentada à Faculdade de Psicologia e de Ciências da Educação Supportive behaviours, defined “as the extent to which team members voluntarily provide assistance to each other when needed during task accomplishment” (Aubé & Rousseau, 2005, p.193), constitute a determinant of Team Effectiveness (Dimas, Rocha, Rebelo, & Lourenço, 2016). The current research aims to clarify further the relationship between Supportive Behaviours and Team Effectiveness criteria, mediated by Team Learning Behaviours. Based on the model of effectiveness Input-Mediator-Outcome-Input (IMOI) from Kozlowski and Ilgen (2006), th…
Image-based 3D reconstruction using traditional and UAV datasets for analysis of road pavement distress
2018
Abstract On local and urban networks, the enduring issue of scarce resources for Maintenance, Rehabilitation, and Reconstruction strategies (MR&R) has led, in many cases, to using unadjusted or poor techniques for road pavement distress detection and analysis, yielding ineffective or even counterproductive results. Therefore, it is necessary to have tools that can carry out quick, reliable and low-cost assessment surveys. This paper aims at validating the use of innovative and low-cost technologies for road pavement analysis, assessing their potentialities for improving the automation and reliability of distress detection. A Structure from Motion (SfM) technique is analyzed at different alt…
Towards More Sustainable Pavement Management Practices Using Embedded Sensor Technologies
2019
Road agencies are constantly being placed in difficult situations when making road maintenance and rehabilitation decisions as a result of diminishing road budgets and mounting environmental concerns for any chosen strategies. This has led practitioners to seek out new alternative and innovative ways of monitoring road conditions and planning maintenance routines. This paper considers the use of innovative piezo-floating gate (PFG) sensors and conventional strain gauges to continuously monitor the pavement condition and subsequently trigger maintenance activities. These technologies can help develop optimized maintenance strategies as opposed to traditional ad-hoc approaches, which often le…
Recommendation of RILEM TC237-SIB on cohesion test of recycled asphalt
2018
This recommendation describes how to evaluate the presence of potentially active bitumen in recycled asphalt (RA) materials through the cohesion test. The experimental protocol is designed according to the research performed by the RILEM Technical Committee 237-SIB ‘‘Testing and characterization of sustainable innovative bituminous materials and systems’’ with the purpose, to develop a new, simple and fast method for the characterization of RA while limiting the need for conventional rheological tests. The guidelines in this recommendation focus on the testing procedure including specimen preparation, data analysis and provide information on the preparation of a tests report.
Passenger Car Equivalents for Heavy Vehicles at Roundabouts. a Synthesis Review
2019
Passenger Car Equivalents (PCEs in the following) are used to transform a mixed fleet of vehicles into a fleet of equivalent passenger cars and to analyze capacity and level-of-service of roads and intersections. Most roundabouts guidelines propose constant values for PCEs but a single PCE value can result improper under heterogeneous traffic conditions. PCEs should be vary with traffic and road conditions and consequently PCEs applied to undersaturated traffic conditions can overestimate the heavy vehicle effect or be not sensitive to the traffic level or characteristics of heavy vehicles. Compared to other at-grade intersections, the interaction between the operational performances of the…
Computational issues in fitting joint frailty models for recurrent events with an associated terminal event.
2020
Abstract Background and objective: Joint frailty regression models are intended for the analysis of recurrent event times in the presence of informative drop-outs. They have been proposed for clinical trials to estimate the effect of some treatment on the rate of recurrent heart failure hospitalisations in the presence of drop-outs due to cardiovascular death. Whereas a R-software-package for fitting joint frailty models is available, some technical issues have to be solved in order to use SASⓇ 1 software, which is required in the regulatory environment of clinical trials. Methods: First, we demonstrate how to solve these issues by deriving proper likelihood-decompositions, in particular fo…
Conceptual Differences Among Functional Size Measurement Methods
2007
The paper focuses on measuring and assessing the relation of adaptive maintenance process and quality of open source software (OSS). A framework for assessing adaptive maintenance process is proposed and applied. The framework consists of six sub- processes. Five OSSs with considerable number of releases have been studied empirically. Their main evolutionary and quality characteristics have been measured. The main results of the study are the following:. 1) Software maintainability is affected mostly by the activities of the 'analysis' maintenance sub-process. 2) Software testability is affected by the activities of all maintenance sub-processes. 3) Software reliability is affected mostly b…
