A new Eliomys from the Upper Miocene of Spain and its implications for the phylogeny of genus
In this paper, we describe a previously unknown species of the glirid Eliomys from the Late Miocene and Early Pliocene Cabriel, Alcoy and Granada basins of southeastern Spain. Eliomys yevesi sp. nov. is characterized by its relative small size, narrow lingual wall and common presence of two centrolophs in the upper molars, and well-developed centrolophids in the lower molars. The new species is the probable ancestor of E. intermedius, which in turn represents the ancestor of the extant E. quercinus. According to its morphologic and biometric features, the origin of E. yevesi sp. nov. is likely to be found in some population of E. truci from the Late Miocene. Based on these affinities, we propose the lineage E. truci–E. yevesi sp. nov.–E. intermedius–E. quercinus, in which there is a trend towards the development of centrolophs, as well as the reduction of accessory crests
A Multi-Criteria Reference Point Based Approach for Assessing Regional Innovation Performance in Spain
[EN] The evaluation of regional innovation performance through composite innovation indices can serve as a valuable tool for policy-making. While discussion on the best methodology to construct composite innovation indices continues, we are interested in deepening the use of reference levels and the aggregation issue. So far, additive aggregation methods are, largely, the most widespread aggregation rule, thus allowing for full compensability among single indicators. In this paper, we present an integrated assessment methodology to evaluate regional innovation performance using the Multi-Reference Point based Weak and Strong Composite Indicator (MRP-WSCI) approach, which allows defining reference levels and different degrees of compensability. As an example of application to the Regional Innovation Scoreboard, the proposed technique is developed to measure the innovation performance of Spain¿s regions taking into account Spanish and European reference levels. The main features of the proposed approach are: (i) absolute or relative reference levels could be previously defined by the decision maker; (ii) by establishing the reference levels, the resulting composite innovation index is an easy-to-interpret measure; and (iii) the non-compensatory strong composite indicator provides an additional layer of information for policy-making (iv) a visualization tool called Light-Diagram is proposed to track the specific strengths and weaknesses of the regions' innovation performance.This research has been partially supported by the Spanish Ministry of Economy and Competitiveness (Project ECO2016-76567-C4-4-R), by the Regional Government of Andalucia (research group SEJ-417), and by the ERDF funds (Project UMA18-FEDERJA-065).Garcia-Bernabeu, A.; Cabello, JM.; Ruiz, F.

A Reference Point-Based Proposal to Build Regional Quality of Life Composite Indicators
[EN] There is a growing interest in research on the role that space plays in defining and measuring well-being or quality of life. In this paper, we propose to evaluate the regional quality of life using the Multi-Reference Point based Weak Strong Composite Indicator approach, to further enhance the quality of the sub-national analysis. The major motivation is to facilitate assessing the regional quality of life performance at different geographical scales and compensability levels. As an example of application, we compute the composite indicators for 19 Spanish regions to paint a comprehensive picture of the regional quality of life using two different geographical scales: the Spanish and the European ones. Moreover, we provide warning signals to regional, national and European policy-makers on the quality of life dimensions in which each region needs further improvements.This research was partially funded by the Spanish Ministry of Economy and Competitiveness (Project PID2019-104263RB-C42), from the Regional Government of AndalucÃa (Project P18-RT-1566), and by the EU ERDF operative program (Project UMA18-FEDERJA-065)Garcia-Bernabeu, A.; Cabello, JM.; Ruiz, F.

Estimation of the Interaction Forces in a Compliant pHRI Gripper
Physical human–robot interaction (pHRI) is an essential skill for robots expected to work with humans, such as assistive or rescue robots. However, due to hard safety and compliance constraints, pHRI is still underdeveloped in practice. Tactile sensing is vital for pHRI, as constant occlusions while grasping make it hard to rely on vision or range sensors alone. More specifically, measuring interaction forces in the gripper is crucial to avoid injuries, predict user intention and perform successful collaborative movements. This work exploits the inherent compliance of a gripper with four underactuated fingers which was previously designed by the authors and designed to manipulate human limbs. A new analytical model is proposed to calculate the external interaction forces by combining all finger forces, which are estimated by using the gripper proprioceptive sensor readings uniquely. An experimental evaluation of the method and an example application in a control system with active compliance have been included to evaluate performance. The results prove that the proposed finger arrangement offers good performance at measuring the lateral interaction forces and torque around the gripper’s Z-axis, providing a convenient and efficient way of implementing adaptive and compliant grasping for pHRI applications.This work was supported by the Universidad de Málaga, project UMA20-FEDERJA-052.

Desarrollo Empresarial y Capital Humano en la región Sureste de Coahuila
El presente trabajo tiene como objetivo determinar si hay un efecto significativo entre capital humano y desarrollo empresarial en la región sureste del Estado de Coahuila, México. Se aplicó un instrumento a 243 personas, utilizando el software de AMOS PASS, en el cual se contemplaron los indicadores del capital humano y desarrollo empresarial, de acuerdo con la hipótesis las relaciones encontradas entre las varianzas de los constructos indican que existe un valor estadÃstico significativo que relaciona a estos constructos. En los resultados se encontró que algunas de las variables fueron: la consideración de pertenencia a la empresa, la percepción de cómo los ve la empresa en función de los conocimientos, y, el reconocimiento de que es el capital humano incrementado por parte de la empresa, demostrando que reconoce este valor como gestor del desarrollo empresarial. De esta manera el capital humano se constituye en uno de los principales factores intervinientes en el desarrollo empresarial.
The present work determines if there is a significant effect between human capital and business development in the southeastern region of the State of Coahuila, Mexico. An instrument was applied to 243 people, using the AMOS PASS software, in which the indicators of human capital and business development were considered, according to the hypothesis, the relationships found between the variances of the constructs indicate that there is a significant statistical value that relates to these constructs. In the results it was found that some of the variables were: the consideration of belonging to the company, the perception of how the company sees them based on knowledge, and, the recognition that it is the human capital increased by the company, demonstrating that it recognizes this value as a manager of business development. In this way, human capital becomes one of the main factors involved in business development
New design parameters for biparabolic beach profiles (SW Cadiz, Spain)
165 profiles of seventy-one beaches along the Gulf of Cadiz (SW, Spain) were studied to improve the formulation of the beach profile in tidal seas. Maritime climate, degree of energy exposure and size of the sand grains were taken into account to study the two sections of the biparabolic profile. The objective of the study was the determination of more accurate formulations of the design parameters for the equilibrium profile that involves tidal seas. These formulations were modelled and validated based on existing profiles to quantify the error existing between the real profile and the modelling. This comparative analysis was extended by considering the formulations proposed by other authors. The best results were obtained with the proposal presented herein
