Efecto de la confianza en la lealtad y el eWOM en las comunidades virtuales de marca.

La confianza en la marca y en la Comunidad Virtual de Marca (CVM) pueden contribuir a la generación de lealtad a la marca y eWOM positivo. Sin embargo, no han sido muchos los estudios empíricos que han incluido ambos tipos de confianza en la evaluación de los resultados de las CVM. Por lo tanto, este trabajo tiene como objetivo explorar cómo la confianza en la marca y la confianza en la comunidad influyen en la lealtad y en el eWOM. Para ello se emplearon datos procedentes de una encuesta realizada a usuarios de CVM que fueron analizados mediante la técnica PLS. Los resultados confirman que la confianza en la marca influye en la lealtad y en el eWOM tanto directamente, como indirectamente a través de la confianza en la CVM. Además, la lealtad favorece la generación de eWOM. Las implicaciones para la práctica de marketing son comentadas.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

Influence of the notch-sharpening technique on styrene-acrylonitrile fracture behavior

The Centre Catala del Plastic and Universidad Rey Juan Carlos laboratories joined forces to investigate the effect of the notch-sharpening technique on the fracture parameters of styrene-acrylonitrile. Contact notch-sharpening techniques, such as razor tapping, razor sliding, and razor broaching, and a noncontact procedure, femtolaser, were analyzed. The fracture values of the samples with notches sharpened via contact techniques were divided into two groups: one with pop-in and the other with no pop-in in the load-displacement records; this resulted in the lowest and highest fracture toughnesses, respectively. The fracture parameters of the specimens with notches sharpened via a femtolaser were between those of the samples with notches sharpened via contact procedures in which pop-in occurred and those in which it did not. To explain these results, the crack front of the nontested specimens after sharpening was investigated in depth, we identified the type of damage and measured its size and the crack tip radii. The morphology of the crack front was related to the fractographic study.Postprint (author's final draft

Modelling Stabilometric Time Series

Stabilometry is a branch of medicine that studies balance-related human functions. Stabilometric systems generate time series. The analysis of these time series using data mining techniques can be very useful for domain experts. In the field of stabilometry, as in many other domains, the key nuggets of information in a time series are concentrated within definite time periods known as events. In this paper, we propose a technique for creating reference models for stabilometric time series based on event analysis. After testing the technique on time series recorded by top-competition sportspeople, we conclude that stabilometric models can be used to classify individuals by their balance-related abilitie

Las habilidades de investigación en estudiantes de Psicología de la Universidad de Guayaquil, Ecuador

La universidad del siglo XXI está cada vez más necesitada de enfrentar los desafíos que la sociedad contemporánea le impone, sobre todo lo relacionado con la producción y la transmisión de la cultura y la formación de profesionales que demandan una elevada preparación desde lo científico y lo investigativo. Por lo que cada vez más, se precisa generar en las instituciones de educación superior, desde la docencia y la investigación una relación articulada entre la teoría y la práctica en los escenarios reales de actuación de los futuros profesionales, con la intención de que los estudiantes universitarios tengan un desarrollo de sus habilidades investigativas. Los autores de este trabajo presentan un grupo de reflexiones teóricas sobre el tema y acciones prácticas orientadas a contribuir al desarrollo de las habilidades investigativas y a la búsqueda de la integración de los saberes que posibilite la formación integral de los futuros profesionales de la carrera de Psicología de la Universidad de Guayaquil, Ecuador. // The twenty-first century university is increasingly needed to meet the challenges that contemporary society imposes related to production and transmission of culture and the training of professionals who demand a high preparation from the scientific and research. As increasingly required generate higher education institutions, from teaching and research articulated relationship between theory and practice in real scenarios of future performance professionals, with the intention that college students have development of research skills. The authors of this paper presents a set of theoretical reflections on the subject and from the subject practical action research methodology aimed at contributing to the development of research skills and the search for knowledge integration that enables the comprehensive training of future Career professionals of Psychology at the University of Guayaquil , Ecuador

La dinámica familiar como génesis de la codependencia

El objetivo de este reporte de caso único es mostrar cómo la dinámica familiar puede entenderse como génesis de una relación codependiente. Desde el enfoque psicoanalítico de Freud y algunas aportaciones significativas de Melanie Klein, se trabajo el fortalecimiento del Yo, haciendo énfasis en la resignificación de las figuras de amor, así como el reconocimiento y verbalización de necesidades, carencias afectivas derivadas de la relación del sujeto con su familia

A Language for Defining Events in Multi-Dimensional Time Series: Application to a Medical Domain

In many domains, like seismography or medicine, time series analysis focuses on particular regions of interest in the time series, known as events, whereas the remainder of the times series contains hardly any useful information. Research into the field of time series events definition has proposed techniques that are only applicable to specific domains. In this paper, we propose an events definition language that is general enough to be able to simply and naturally define time series events in any domain. The proposed language has been applied to the definition of time series events generated by stabile metric systems within the branch of medicine dealing with balance related functions in human beings

Comparing Time Series Through Event Clusterin

The comparison of two time series and the extraction of subsequences that are common to the two is a complex data mining problem. Many existing techniques, like the Discrete Fourier Transform (DFT), offer solutions for comparing two whole time series. Often, however, the important thing is to analyse certain regions, known as events, rather than the whole times series. This applies to domains like the stock market, seismography or medicine. In this paper, we propose a method for comparing two time series by analysing the events present in the two. The proposed method is applied to time series generated by stabilometric and posture graphic systems within a branch of medicine studying balance-related functions in human beings
