Benchmarking of airports service quality by a new fuzzy MCDM approach
2015
Recent approaches to the service quality evaluation problem are focused on the employment of multi-criteria decisionmaking (MCDM) procedures, since processes related to service quality evaluation presentmeaningful communality elements to MCDM ones. Based on such assumption, in the present paper a new fuzzy MCDMapproach is developed tocomparatively evaluate passenger service quality of the international airports inSicily (Italy). In particular, by incorporating the respondents confidence level and degree of optimism on fuzzy assessments, quality scores of main airport service criteria are estimated, whereas ELECTRE multi criteria decision support methodis proposed to point out theservices qu…
Vil økt fysisk aktivitet kunne redusere andelen trygdemottakere? : En case-studie basert på deltakere ved Aktiv på dagtid, Aust-Agder

Ajuste psicológico en cuidadores familiares de adolescentes: un análisis longitudinal durante el confinamiento por la COVID-19 en España
2021
Debido al confinamiento por la COVID-19, las familias españolas tuvieron que adaptarse a nuevas situaciones y rutinas. El objetivo de esta investigación ha sido conocer qué variables explicaban el ajuste psicológico de cuidadores familiares de adolescentes ante la COVID-19, mediante un estudio longitudinal (evaluando primero a las 2-3 semanas del inicio del estado de alarma y después tras 8 semanas de su instauración en España). Participaron 32 progenitores de adolescentes. Tras aceptar participar, se evaluó: clima familiar, satisfacción vital, regulación emocional, resiliencia y psicopatología. Se realizaron modelos de análisis comparativo cualitativo de conjuntos difusos (fsQCA). Nuestros…
Improving Interpolants for Linear Arithmetic
2015
Craig interpolation for satisfiability modulo theory formulas have come more into focus for applications of formal verification. In this paper we, introduce a method to reduce the size of linear constraints used in the description of already computed interpolant in the theory of linear arithmetic with respect to the number of linear constraints. We successfully improve interpolants by combining satisfiability modulo theory and linear programming in a local search heuristic. Our experimental results suggest a lower running time and a larger reduction compared to other methods from the literature.
Effects of a glyphosate-based herbicide on survival and oxidative status of a non-target herbivore, the Colorado potato beetle (Leptinotarsa decemlin…
2018
Abstract Glyphosate is the globally most used herbicide against a wide range of weeds. Glyphosate has been considered safe to animals as it mainly targets physiological pathways in plants. However, recent toxicological studies have revealed that glyphosate can cause various toxic effects also on animals. In this study, we investigated the direct toxic effects of a glyphosate-based herbicide (GBH, Roundup® Bio) on 1) survival and 2) oxidative status of a non-target herbivore by using Colorado potato beetles (Leptinotarsa decemlineata), originating from Poland and USA, as model species. Larvae were randomly divided into three groups: 1) high concentration (100% Roundup Bio, 360 g/l), 2) low c…
Contributo para o estudo psicométrico da versão portuguesa do Cuestionario de Satisfacción Laboral S20/23
2010
Job satisfaction is understood through its dual role on organization productivity and employees achievement (Smith, 1998). The use of instruments to measure it in Portugal, has been the subject of several studies, such as the adaptation of the Cuestionario de Satisfacción Laboral S20/23 (Meliá & Peiró, 1989) to Portuguese population carried out by Pocinho and García (2008). This study is a further contribution to the study of the psychometric qualities of this instrument. The results on a sample of 136 Portuguese employees show that the questionnaire presents the adequate requirements of internal consistency (.95), test-retest reliability, and convergent validity (correlation of .84 with th…
Apmierinātības ar darbu saistība ar apmierinātību ar komunikāciju un darbaholismu
2017
Šī pētījuma mērķis ir noskaidrot apmierinātības ar darbu sakarības ar apmierinātību ar komunikāciju un darbaholismu. Noskaidrot, vai pastāv statistiski nozīmīgas sakarības starp apmierinātību ar darbu un apmierinātību ar komunikāciju, kā arī starp apmierinātību ar darbu un darbaholismu. Papildus noskaidrot, kā apmierinātība ar komunikāciju un darbaholisms prognozē apmierinātību ar darbu organizācijā. Pētījuma izlasi veido 93 respondenti, dažādos uzņēmumos strādājoši, ar dažādiem darba stāžiem, izglītību un amatu, no kuriem 52 = sievietes un 41 = vīrietis, vecumā no 22 līdz 65 gadi. Pētījuma datu iegūšanai tika izmantotas trīs aptaujas. Apmierinātība ar komunikāciju aptauja (Communication sa…
Uztvertais sociālais atbalsts, apmierinātība ar partnerattiecībām un depresijas simptomi sievietēm 4 – 6 nedēļas pēc dzemdībām
2017
Pētījuma jautājumi, kuriem vēlos noskaidrot atbildes pētījumā rezultātā ir, kāda saistība pastāv starp uztverto sociālo atbalstu, apmierinātību ar partnerattiecībām un depresijas simptomiem sievietēm 4 – 6 nedēļas pēc dzemdībām. Otrs pētījuma jautājums ir noskaidrot, kā apmierinātība ar partnerattiecībām un uztvertais sociālais atbalsts prognozē depresijas simptomus sievietēm 4 – 6 nedēļas pēc dzemdībām. Pētījumā piedalījās 31 sieviete, kura bija 4 – 6 nedēļas pēc dzemdībām. Svarīgi nosacījumi bija, lai sievietei būtu piedzimis pirmais bērniņš un lai viņš būtu vesels, kas tika novērtēts pēc Apgares jaundzimušā veselības stāvokļa. Pētījumā tika izmantoti trīs pētījuma instrumenti. Lai noskai…
Self-reported playing time and justice as predictors of coach satisfaction: An analysis of elite ice-hockey and handball players
2020
Intrateam competition for specific roles and playing time is a continuous imperative process in elite sport teams. The assessment of this competition is done by the coach and the outcome of this process has a significant impact on the team and the players. The following hypothesis was put forward for testing: Self-reported playing time and perceptions of justice among elite ice-hockey and handball players predict their satisfaction with the coach. Elite ice-hockey and handball players (N = 231) reported playing time and completed the Perceived Justice and Athlete Satisfaction Questionnaires. Hierarchical multiple regression analyses show that self-reported playing time, distributive justice…
Eficacia del aprendizaje servicio en dimensiones académicas, personales y sociales clave, y su incidencia en la satisfacción estudiantil en la docenc…
2017
El trabajo de investigación que se presenta se justifica por la centralidad que otorga la doctoranda a las metodologías docentes para implementar una docencia de calidad. Por ello, aun advirtiendo las dificultades, incluso las contrariedades e intereses en algunos aspectos de la unificación del EEES, el hecho de que haya considerado a las metodologías docentes innovadoras, uno de los ejes del nuevo escenario educativo europeo, se valora como una medida eficaz para la Universidad. Además, en este escenario cada vez suena con más fuerza el concepto de "desarrollo sostenible" en la Universidad y se señala a las metodologías como una de las claves para articular el modelo de educación por compe…
