Arviointi osana kuntouttavan työtoiminnan voimaantumisprosessia : voidaanko ihmisen voimaantumista havainnollistaa ja arvioida?
2010
Tutkimuksen tavoitteena oli muodostaa näkemystä ihmisen motivoitumiseen ja voimaantumiseen vaikuttavista tekijöistä ja tuoda esille systemaattisen tilannearvioinnin merkitystä tavoitteellisessa sosiaalityössä. Tutkimuksessa olen kehittänyt laadullista mittaria käytännön työvälineeksi, joka auttaa asiakasta ja sosiaalityöntekijää hahmottamaan asiakkaan tilannetta ja arvioimaan siinä tapahtuvia muutoksia voimaantumisen näkökulmasta. Vuonna 2001 voimaan tullut kuntouttavan työtoiminnan laki sisältää kaksi palvelua, aktivointisuunnitelman laatimisen ja kuntouttavan työtoiminnan. Tutkimuksessa tarkastelen kuntouttavaa työtoimintaa yksilöllisenä voimaantumisprosessina, jonka tavoitteena on saada …
MOTIVACIÓN Y ESTILO ATRIBUCIONAL SOBRE EL RENDIMIENTO ACADÉMICO EN EDUCACIÓN INFANTIL
2016
El presente trabajo tiene como objetivo examinar el poder predictivo de variables del sistema motivacional sobre las habilidades iniciales de lectura y matemáticas en una muestra de niños de Educación Infantil. Participaron 209 preescolares (5-6 años) y sus maestros. Se evaluaron las habilidades matemáticas de conteo, conocimiento de los números, cálculo y resolución de problemas. Para determinar el rendimiento en lectura se administraron tareas de identificación de letras y de lectura de palabras. Respecto al sistema motivacional, se analizaron las variables de competencia-motivación, atención-persistencia y actitud hacia el aprendizaje, así como las dimensiones de internalidad, globalida…
Motivation to Study for PhD Degree: Case of Latvia
2014
AbstractThis paper studies what goals individuals pursue when enrolling in doctoral studies and how it affects the characteristics of the university they find important for choosing it and information sources on doctoral programme they find useful. It uses data collected in 2014 from PhD students and PhD candidates in 14 universities in Latvia and from students born in Latvia but studying abroad. The main result is substantial heterogeneity of goals by field of study, allowing to divide the latter into three groups. Group 1 contains arts & humanities, economics, and education & psychology. Compared to it, students from Group 2 (biology, agriculture, environment & geoscience; physics, mathem…
Design and Performance Evaluation of a High Power-Density EMI Filter for PWM Inverter-Fed Induction-Motor Drives
2016
This paper presents the design of an electromagnetic interference (EMI) filter for a low-voltage high-current induction-motor drives supplied by dc power grids. In order to effectively design the EMI filter, a suitable common-mode/differential-mode (CM/DM) separation technique has been used. Due to the high operating currents, the software-based separation technique using time-domain measurements has been applied. The proposed technique allows the CM and DM sections of the EMI filter to be properly selected in a more economical way, i.e., without the need of a dedicated hardware or costly radio frequency (RF) instrumentation. The design has been done according to a power-density criterion. …
FACTORES HUMANOS ASOCIADOS A LOS ACCIDENTES MORTALES DE MOTOCICLETAS SCOOTER EN ESPAÑA
2017
Resumen Los accidentes de motocicleta son uno de los problemas de seguridad vial más importantes a nivel mundial. Hay una escasez de estudios específicos sobre las características de la accidentalidad de las motocicletas de tipo scooter, motivada por la falta de una definición precisa de este tipo de motocicleta y de la identificación de los distintos tipos de vehículos de dos ruedas en los registros de accidentes. El objetivo de este trabajo es determinar las características de los 293 conductores de motocicletas scooter fallecidos en España durante el periodo 2006-2011. Se realizaron análisis descriptivos y de asociación en función de la naturaleza de las variables. Los resultados de los …

Multicriteria Decision Aiding for Planning Renewable Power Production at Moroccan Airports
2022
This study is about multicriteria decision aiding (MCDA) for the green airports program of the Moroccan Airport Authority ONDA. The goal of the program is to develop significant amounts of renewable power at airports. In particular, ONDA wants to select airports at which large solar and wind power parks should be built. Multiple criteria, including economy, technical feasibility, and environmental concerns, must be considered simultaneously. In this study, we apply Stochastic Multicriteria Acceptability Analysis (SMAA) for ranking the candidates to be developed into green airports. The analysis is conducted in phases with different sets of criteria. This study is the first application of MC…
Constant Power Model in Arm Rotation—A New Approach to Hill’s Equation
2014
The purpose of this study was to further develop the constant power model of a previous study and to provide the final solution of Hill’s force-velocity equation. Forearm and whole arm rotations of three different subjects were performed downwards (elbow and shoulder extension) and upwards (elbow and shoulder flexion) with maximum velocity. These arm rotations were recorded with a special camera system and the theoretically derived model of constant maximum power was fitted to the experimentally measured data. The moment of inertia of the arm sectors was calculated using immersion technique for determining accurate values of friction coefficients of elbow and whole arm rotations. The experi…
Modeling the force – velocity relationship in arm movement
2012
Modeling the force-velocity dependence of a muscle-tendon unit has been one of the most interesting objectives in the field of muscle mechanics. The so-called Hill’s equation [1,2] is widely used to describe the force-velocity relationship of muscle fibers. Hill’s equation was based on the laboratory measurements of muscle fibers and its application to the practical measurements in muscle mechanics has been problematic. Therefore, the purpose of this study was to develop a new explicit calculation method to determine the force-velocity relationship, and test its function in experimental measurements. The model was based on the motion analysis of arm movements. Experiments on forearm rotatio…
