Discurso de entrenadores de balonmano en función de variables derivadas de la competición: introducción a una perspectiva secuencial
2017
El foco de la presente tesis doctoral se sitúa sobre la figura del entrenador. Dada la creciente importancia del deporte a nivel económico, financiero, político y mediático, el número de estudios sobre entrenadores es sorprendentemente pequeño (Mowat, 2004). El mismo autor añade que para los entrenadores es evidente que se sabe mucho más sobre la preparación de sus equipos, lo que favorece el rendimiento y el desarrollo de los jugadores y lo que constituye una buena práctica, que sobre los mismos ámbitos referidos a ellos mismos. Todos los entrenadores están muy bien entrenados para analizar las tácticas del oponente al detalle; sin embargo, el problema aparece cuando tienen que explicar de…
Variational approach for analysis of harmonic vibration and stabiligy of moving panels
2014
In this paper, the stability of a simply supported axially moving elastic panel (plate undergoing cylindrical deformation) is considered. A complex variable technique and bifurcation theory are applied. As a result, variational equations and a variational principle are derived. Analysis of the variational principle allows the study of qualitative properties of the bifurcation points. Asymptotic behaviour in a small neighbourhood around an arbitrary bifurcation point is analyzed and presented. It is shown analytically that the eigenvalue curves in the (ω, V0) plane cross both the ω and V0 axes perpendicularly. It is also shown that near each bifurcation point, the dependence ω(V0) for each m…
Towards essential visual variables in user interface design
2014
This paper focuses on visual variables in user interface design from the user perspective. Visual design of user interfaces is essential to users interacting with different software. The study is conducted with 3E-templates for users to express their impressions by writing and drawing regarding visual website design. The data is analyzed with qualitative content analysis through interpretation framework. The results of this study provide new insights into user-centered visual user interface design. The results indicate which are the most essential visual variables in user interface design and therefore should be emphasized in user-centered design that promotes positive UX and, thus, benefit…
Prescription opioid use and employment : A nationwide Finnish register study
2021
Background: The secular decline in labor market participation and the concurrent increase in opioid use in many developed countries have sparked a policy debate on the possible connection between these two trends. We examined whether the use of prescription opioids was connected to labor market outcomes relating to participation, employment and unemployment among the Finnish population. Methods: The working-age population (aged 19–64 years) living in Finland during the period 1995–2016 was used in the analyses (consisting of 67 903 701 person-year observations). Lagged values of prescription opioid use per capita were used as the exposure. Instrumental variables (IV) estimation method was u…
