Website Architecture, Information Flows and Cognitive Models

This paper explores the relation between new digital genres configuration and their users’ previous knowledge patterns from an interlinguistic perspective. More precisely, first we analyse two models that underlie the formal architecture of websites. For that purpose we introduce diverse pieces of software that allow for visualization of website organization in terms of nodes and links. Then, we show the most entrenched metaphoric models that provide cognitive tools for users to understand website configuration and usage, in an English speaking culture. Finally, we discuss to what extent these models can be transferred and learned by users from other cultures, particularly in Spanish speaking communitie

Novel bio-inspired 3D porous scaffold intended for bone-tissue engineering: Design and in silico characterisation of histomorphometric, mechanical and mass-transport properties

The design of novel biomimetic bone tissue scaffolds (BTS) using computer aided design (CAD) technology is challenging additive manufacturing technologies. At the microstructure level, BTS should mimic bone histomorphometry and assure optimum mass transport and mechanical properties. In this study, a novel BTS has been designed, by using a parametric and variational CAD method, to model a bio-inspired and interconnected porous structure. The mechanical (elastic modulus) and the fluid mass transport (permeability) properties have been computed and compared to other implicit surfaces modelling scaffolds. The results showed that the new BTS could be tuned during the design stage to match the microstructure and the histomorphometry properties of trabecular bone. Those with porosities between 0.7 and 0.9 and highly smooth curvatures were the most appropriates. The new BTS, once appropriately designed, could be made/manufactured by 3D printing technology with an internal microstructure mimicking the local bone properties of the selected bone volumes of interest, for example, those coming from computed tomography medical images.Peer ReviewedPostprint (published version

Credibility to attract, trust to stay: the mediating role of trust in improving brand congruence in sports services

This research aims to demonstrate the mediating role of brand trust in the relationship between credibility and users' congruence with a sports services brand. The analysis was carried out using EQS 6.3 to perform the four required steps of the analysis (and the Sobel test was conducted for a public sports service and a private sports service. The results confirm the full mediation effect of brand trust in the case of the private service and a partial mediation for the public service. Therefore, this study confirms that credibility, in the presence of trust, ceases to have an influence on the congruence of users with the brand, which suggests that credibility is important at an initial stage to attract the user, but at more advanced stages, trust must be developed to ensure that users are more congruent with the brand and can, therefore, be identified with it and be more loyal

Emulation of an OWC Ocean Energy Plant With PMSG and Irregular Wave Model

Ocean energy is a promising resource for renewable electricity generation that presents many advantages, such as being more predictable than wind energy, but also some disadvantages such as large and slow amplitude variations in the generated power. This paper presents a hardware-in-the-loop prototype that allows the study of the electric power profile generated by a wave power plant based on the oscillating water column (OWC) principle. In particular, it facilitates the development of new solutions to improve the intermittent profile of the power fed into the grid or the test of the OWC behavior when facing a voltage dip. Also, to obtain a more realistic model behavior, statistical models of real waves have been implemented

Durability of concrete with electric arc furnace slag aggregate

The durability of concrete mixes with EAF slag as aggregate (HS) is studied; mixes with limestone (HC) and barite (HAB) aggregates were used as reference for structural and heavy-weight applications, respectively. Compressive strength, elastic modulus, water penetration under pressure, wet-dry cycles, freeze-thaw cycles, influence of environmental condition and leaching tests were conducted. The results indicate that HS tends to present higher depth of water penetration under pressure, a slightly higher expansion, higher carbonation depth and similar compressive strength than reference HC. Should be payed attention to the formation of stain points on HS concrete surface subjected to wet-drying cycles.Peer ReviewedPostprint (author's final draft

Finite element analysis of narrow dental implants

Narrow-diameter implants (NDIs) traditionally have been associated to higher rates of failure in comparison with regular-diameter implants (RDIs) and wide-diameter implants (WDIs), since they generate a more unfavorable stress distribution in peri-implant bone. However, it is well known that the load sharing effect associated with prostheses supported by multiple implants (also called splinted prostheses) affords mechanical benefits. The present study involves finite element analysis (FEA) to determine whether the risks linked to NDIs could be mitigated by the mechanical advantages afforded by the splinting concept. For this purpose, a three-dimensional (3D) model of a real maxilla was reconstructed from computed tomography (CT) images, and different implants (NDIs, RDIs and WDIs) and prostheses were created using computer-aided design (CAD) tools. Biting forces were simulated on the prostheses corresponding to three different rehabilitation solutions: single-implant restoration, three-unit bridge and all-on-four treatment. Stress distribution around the implants was calculated, and overloading in bone was quantified within peri-implant volumes enclosed by cylinders with a diameter 0.1 mm greater than that of each implant. The mechanical benefits of the splinting concept were confirmed: the peri-implant overloaded volume around NDIs splinted by means of the three-unit bridge was significantly reduced in comparison with the nonsplinted condition and, most importantly, proved even smaller than that around nonsplinted implants with a larger diameter (RDIs). However, splinted NDIs supporting the all-on-four prosthesis led to the highest risk of overloading found in the study, due to the increase in compressive stress generated around the tilted implant when loading the cantilevered molar.Peer ReviewedPostprint (author's final draft

The influence of gender and academic training in the entrepreneurial intention of physical activity and sport sciences students

Objeto: El objetivo del presente artículo es conocer si existen diferencias en las variables que explican la intención de emprender de los estudiantes universitarios de Ciencias de la Actividad Física y el Deporte atendiendo a la formación y al género de éstos. Diseño/metodología/enfoque: Para conocer las intenciones de emprender y las distintas variables relacionadas con el emprendimiento se utilizó un cuestionario previamente validado. Éste fue administrado a 578 estudiantes pre-graduados (1er - 4º curso) y post-graduados de Ciencias de la Actividad Física y el Deporte de Valencia. Aportaciones y resultados: Se encontraron diferencias significativas (p≤0.05) en las variables que predicen la intención de emprender según género y formación de los estudiantes. En ambos géneros la actitud y el control percibido resultaron ser las variables predictoras de la intención de emprender, y en los hombres también la norma subjetiva. Limitaciones: La muestra de estudiantes sólo pertenece a la titulación de Ciencias de la Actividad Física y el Deporte de Valencia, por lo que los resultados no son extrapolables a toda la población de estudiantes. Implicaciones prácticas: Para favorecer el espíritu emprendedor y de esta manera formar graduados más preparados para su inserción en el mundo laboral se deben crear programas que fomenten la actitud hacia la conducta del emprendimiento y el control del comportamiento percibido. Implicaciones sociales: Aumentar el número de emprendedores en el sector deportivo, reduciendo la brecha de género, así como mejorar la calidad del emprendimiento, ya que éste es un aspecto clave debido al impacto positivo que este fenómeno genera sobre la economía. Originalidad / Valor añadido: Conocer si existen diferencias en función de la formación y el género debido a la masiva incorporación de la mujer al mundo laboral deportivo y su baja intención de emprender, con el objetivo de formar tanto a graduados como graduadas con habilidades emprendedoras.Purpose: The objective of this article is to know if there are differences in the variables that explain the entrepreneurial intention of the Physical Activity and Sport Science students addressing academic training and gender of them. Design/methodology: To know entrepreneurial intentions and the different variables related to entrepreneurship, a questionnaire previously validated was used. The questionnaire was provided to 578 students pre-graduated (1st-4th course) and post-graduate of Physical Activity and Sport Science degree of Valencia. Findings: Statistically significant differences (p ≤ 0.05) in the variables that predict entrepreneurial intention of Physical Activity and Sport Science students by gender and training were found. In both genders, the attitude towards entrepreneurship and the perceived behavior control were the predictors of entrepreneurial intentions and in men also the subjective norms. Research limitations/implications: The students sample belongs only to the Physical Activity and Sport Science degree of Valencia, so the results cannot be extrapolated to the entire population. Practical implications: It should be developing the attitude toward the behavior of entrepreneurship and perceived behavioral control to promote entrepreneurship. In this way, the graduates will be more prepare for insertion into the working world. Social implications: To increase the number of entrepreneurs (male and female) in the sports sector throughout the education, reducing the gender gap in entrepreneurship and improve the quality of entrepreneurship, as this is a key issue because of the positive impact that this phenomenon generates on the economy Originality/value: It is interesting to know the predictor variables of entrepreneurial intentions, and to know if there are differences based on education and gender due to the massive entry of women into the sport workplaces and low intention to undertake of the. So it is quite important training in the best way, both graduates (male and female) with entrepreneurial skills.Peer Reviewe
