Attitude Function as a Moderator in Values-Attitudes-Behavior Relations
2011
Abstract The aim of the present study was to find whether attitude functions could be useful in predicting aberrant driving. One of the attitudes functions is to express values; hence, we hypothesized that attitudes whose function is to express values will better predict traffic violations. We explored: (i) values in relation to attitudes towards aberrant driving behavior by regression analysis; (ii) and we explored moderating role of attitude functions in value-attitude-behavior relations. The study sample included 305 respondents who completed self-report questionnaires. Current research confirms previous results and also shows that values do predict attitudes when individual had formed h…
Career intentions of Australian physical education teachers
2015
The purpose of this study was to investigate Australian physical education (PE) teachers’ career intentions and factors influencing their intentions. A sample ( N = 234) of Western Australian PE teachers responded to a questionnaire determining PE teachers’ work and the primary motivators for intention to leave the profession. Half (51.3%) of the respondents wanted a change from their current PE teacher job and 39.8% were intending to leave PE teaching. The most frequent reasons for wanting to leave PE related to: non-use of expertise, workload, school administration, and lack of opportunities for personal and professional development. Consideration should be given to mediation strategies t…
Application of a Knowledge Discovery Process to Study Instances of Capacitated Vehicle Routing Problems
2020
Vehicle Routing Problems (VRP) are computationally challenging, constrained optimization problems, which have central role in logistics management. Usually different solvers are being developed and applied for different kind of problems. However, if descriptive and general features could be extracted to describe such problems and their solution attempts, then one could apply data mining and machine learning methods in order to discover general knowledge on such problems. The aim then would be to improve understanding of the most important characteristics of VRPs from both efficient solution and utilization points of view. The purpose of this article is to address these challenges by proposi…
Multicenter Consistency Assessment of Valvular Flow Quantification With Automated Valve Tracking in 4D Flow CMR
2021
OBJECTIVES This study determined: 1) the interobserver agreement; 2) valvular flow variation; and 3) which variables independently predicted the variation of valvular flow quantification from 4-dimensional (4D) flow cardiac magnetic resonance (CMR) with automated retrospective valve tracking at multiple sites. BACKGROUND Automated retrospective valve tracking in 4D flow CMR allows consistent assessment of valvular flow through all intracardiac valves. However, due to the variance of CMR scanners and protocols, it remains uncertain if the published consistency holds for other clinical centers. METHODS Seven sites each retrospectively or prospectively selected 20 subjects who underwent whole …
Estimates for Divergence Velocities of Axially Moving Orthotropic Thin Plates
2014
Some models for axially moving orthotropic thin plates are investigated analytically via methods of complex analysis to derive estimates for critical plate velocities. Linearised Kirchhoff plate theory is used, and the energy forms of steady-state models are considered with homogeneous and inhomogeneous tension profiles in the cross direction of the plate. With the help of the energy forms, some limits for the divergence velocity of the plate are found analytically. In numerical examples, the derived lower limits for the divergence velocity are analysed for plates with small flexural rigidity. peerReviewed
Theory and regulation of liquidity risk management in banking
2016
Liquidity risk is now more important than it used to be in the past. The financial crisis has emphasised the importance of liquidity risk to the functioning of banking and financial system. The paper presents a theoretical and regulatory investigation of two types of liquidity risk: funding liquidity risk and market liquidity risk. The paper analyses the different approaches to measure the impact of funding and market liquidity risk in the economics and management of banks. The paper provides also an analysis of the organisational implications of the asset and liability management perspective of liquidity risk. Liquidity risk does not need to be covered by equity but by an adequate volume o…
Mise en relation de données relatives aux procédés de fabrication, écoconception, composition et qualité des produits laitiers à l'aide d'une base de…
2019
L’objectif de cette étude est de permettre la mise en relation de données hétérogènes, issues de projets divers grâce à leur implémentation dans une base de données appelée BaGaTel, structurée selon une ontologie. L’exemple choisi pour cette mise en relation de données est le fromage, dont les différents paramètres et spécificités ont été renseignés dans l’ontologie.
Some contributions in disease mapping modeling
2020
Disease mapping ha recibido un gran interés durante las tres últimas décadas. Esta área de investigación persigue el estudio de la distribución geográfica de eventos relacionados con la salud, tales como la mortalidad o la incidencia de enfermedades, agregados en unidades geográficas, con el fin de identificar principalmente aquellas localizaciones que presentan un mayor riesgo. La aplicación de métodos estadísticos avanzados para llevar a cabo las estimaciones de los riesgos resulta fundamental para obtener estimaciones precisas y profundizar en el entendimiento de la distribución geográfica de las enfermedades. En esta tesis nos centramos en la aplicación y evaluación de varias propuestas…
Copulation duration, but not paternity share, potentially mediates inbreeding avoidance in Drosophila montana
2014
Studying the incidence of inbreeding avoidance is important for understanding the evolution of mating systems, especially in the context of mate choice for genetic compatibility. We investigated whether inbreeding avoidance mechanisms have evolved in the malt fly, Drosophila montana, by measuring mating latency (a measure of male attractiveness), copulation duration, days to remating, offspring production, and the proportion of offspring sired by the first (P1) and second (P2) male to mate in full-sibling and unrelated pairs. SNP markers were used for paternity analysis and for calculating pairwise relatedness values (genotype sharing) between mating pairs. We found 18 % inbreeding depressi…
