    La acción social empresarial como componente de la responsabilidad social corporativa

    Get PDF
    Si bien es verdad que términos como Marketing con Causa, Marketing Social Corporativo o Solidaridad Empresarial son más conocidos en la última década, no cabe duda de que hoy se impone la Responsabilidad Social Corporativa (RSC) como un concepto mucho más amplio y de plena actualidad en el management empresarial. Todo ello deviene de la importancia que los ciudadanos conceden a las empresas socialmente responsables entendidas de manera intuitiva como aquéllas que, además de ser entidades económicas en sentido tradicional, tienen especialmente en cuenta una serie de factores relacionados con su integración en la sociedad. Entre ellos destacan la contribución de sus productos al bienestar general, el cumplimiento de la normativa vigente, su comportamiento ético y el de su equipo directivo, la buena relación con los trabajadores, el respeto al medio ambiente o el apoyo a las personas más desfavorecidas de su entorno. En este sentido, la Fundación Empresa y Sociedad define la Acción Social Empresarial (ASE) como la dedicación de recursos humanos, financieros o técnicos a proyectos de desarrollo de la sociedad en beneficio de personas desfavorecidas y gestionadas en sentido empresarial en las siguientes áreas: formación profesional y empleo, educación, salud y asistencia social. No obstante, parece ser que la Acción Social Empresarial es el componente más desatendido de la gestión empresarial, quizá porque las empresas consideran que ésta corresponde más al ámbito de la iniciativa individual y que por tanto es un tema menor que tiene más relación con la caridad o la filantropía. En esta comunicación se plantea como objetivo profundizar en el alcance que tiene la Acción Social Empresarial como elemento integrante de la Responsabilidad Social Corporativa. ¿Qué grado de implantación tiene la Acción Social Empresarial?. ¿Qué valor añadido tiene para los ciudadanos?. ¿Realmente se perciben las diferencias entre Acción Social Empresarial y Responsabilidad Social Corporativa?. ¿Qué sectores son los más proclives al desarrollo de la Acción Social Empresarial?

    Axes of relationship value between manufacturers and retailers

    Purpose - The purpose of this paper is to define the relationship strategy of manufacturers with their retail customers through the identification of axes for the creation of relationship value. Design/methodology/approach - A survey was carried out and 219 valid questionnaires were completed and returned by the purchasing managers of retail companies in the furniture sector. The model was estimated using the partial least squares approach. Findings - The results revealed three axes of value creation: the core axis, the information and communication technologies (ICTs) axis, and the access axis. These axes included the benefits and costs related to the product and the service provided, the ICTs of the manufacturing project, and the relationships with the sales personnel. Research limitations/implications - Due to the size of the sample, the authors were unable to analyse the potential unobserved heterogeneity of the sample. The authors would suggest that this aspect should be analysed in future research in order to attempt to segment clients. Practical implications - Seller support is the main element of value creation. The importance of the efforts made by management to strengthen the capacities of the field force may be highlighted. Originality/value - The main contribution of this study has been to increase the level of abstraction of the study of relationship value through the identification and modelling of its axes of creation for the under-researched retailers-suppliers relationship

    Objective: Onychocryptosis is one of the most prevalent onychopathies, being a frequent reason for consultation in podiatric clinical practice. Conservative treatments are the first therapeutic choice, with nail remodeling using clotrimazole gel emerging as an alternative, although its medium-term effectiveness is unknown. The objective of this study was therefore to compare the efficacy of the technique of nail retraining using gauze bandaging with that of nail remodeling for the conservative treatment of stage I and IIA onychocryptosis. Methods: An analytical, randomized clinical trial study was performed following a longitudinal and prospective design. A sample was selected of 20 subjects presenting stage I and IIA onychocryptosis. Of these, 10 cases formed the group of nail retraining using gauze bandaging, and the other 10 the nail remodeling group. The presence of recurrence in a 3-month period was evaluated. Results: Before the intervention, the patients in the retraining group presented pain of 6.7 ± 1.9 vs. 6.8 ± 1.6 in the remodeling group, with no significant difference between the two (p = 0.900). After the 3-month follow-up period, seven of the retraining group patients presented recurrence of onychocryptosis vs. only one in the remodeling group. Conclusion: The technique of nail remodeling has a lower recurrence rate than that of nail retraining with gauze bandaging, with the pain, inflammation, and infection reported being less, and with greater patient satisfactio

    La educación se enfrenta a grandes retos, uno de ellos es el cambio metodológico actual, debemos plantearnos un cambio que deje a un lado la memorización de conocimientos y datos, y optar por otras metodologías más globales y que atiendan más a las capacidades cognitivas, reflexivas y emotivas. Una manera de atender este cambio es a través del área artística, aprovechando el pensamiento visual y las artes visuales para llegar a las niñas y niños, convirtiendo el arte como un medio de conocimiento. Con este fin se ha desarrollado una propuesta didáctica que consiste en una serie de intervenciones artísticas dispuestas en el Jardín Botánico de la calle Valentín Carderera de Huesca, que invitan a la reflexión medioambiental. Al ser un espacio público, este jardín se convierte en un agente educador dentro de la ciudad y abierto a todo el mundo

    Regulon-Specific Control of Transcription Elongation across the Yeast Genome

    Get PDF
    Transcription elongation by RNA polymerase II was often considered an invariant non-regulated process. However, genome-wide studies have shown that transcriptional pausing during elongation is a frequent phenomenon in tightly-regulated metazoan genes. Using a combination of ChIP-on-chip and genomic run-on approaches, we found that the proportion of transcriptionally active RNA polymerase II (active versus total) present throughout the yeast genome is characteristic of some functional gene classes, like those related to ribosomes and mitochondria. This proportion also responds to regulatory stimuli mediated by protein kinase A and, in relation to cytosolic ribosomal-protein genes, it is mediated by the silencing domain of Rap1. We found that this inactive form of RNA polymerase II, which accumulates along the full length of ribosomal protein genes, is phosphorylated in the Ser5 residue of the CTD, but is hypophosphorylated in Ser2. Using the same experimental approach, we show that the in vivo–depletion of FACT, a chromatin-related elongation factor, also produces a regulon-specific effect on the expression of the yeast genome. This work demonstrates that the regulation of transcription elongation is a widespread, gene class–dependent phenomenon that also affects housekeeping genes

    Switching Pattern Improvement for One-Cycle Zero-Integral-Error Current Controller

    Full text link
    [EN] The one-cycle current control is a non-linear technique based on the cycle-by-cycle calculation of the ON time of the power converter switches. Its application is not common in tracking fast-changing reference currents, due to the necessity of fast and accurate measurements, and high-speed computing. In a previous study, a one-cycle digital current controller based on the minimization of the integral error of the current was developed and applied to the control of a three-phase shunt active power filter. In the present work, the one-cycle controller has been improved by proposing a new switching pattern. It allows an easy implementation that reduces the critical computational cost and avoids the main drawbacks of the previous implementation. The controller has been applied in a three-leg four-wire shunt active power filter, including a stability analysis considering the proposed switching pattern. Simulated and experimental results are presented to validate the proposed controller.Orts-Grau, S.; Balaguer-Herrero, P.; Alfonso-Gil, JC.; Martínez-Márquez, CI.; Martínez-Navarro, G.; Gimeno Sales, FJ.; Segui-Chilet, S.

    This study was undertaken to analyse differences in physical, psychological and anthropometric markers related to success in olympic wrestling. Thirty seven male Freestyle and Greco-Roman wrestlers were assigned to two groups according to their competitive level: Elite (n = 18) and Amateur (n = 19). All the subjects underwent an anthropometric assessment, a complete physical fitness test battery (maximal dynamic and isometric strength, muscle power output, crank-arm wingate test, running speed and hamstring extensibility) as well as a psychological characteristics assessment associated with sport performance through the Psychological Performance Inventory. The elite wrestlers were older, had more training experience, a fat free mass, maximal dynamic and isometric strength, muscle power, mean and peak power during wingate testing and significantly higher self- perceptions of self-control, attitude control and the total average of the sum of all the scales. These results suggest that the optimisation of neuromuscular and anaerobic metabolism and several psychological performance markers are conditional and thus predictive of success in wrestling

    One-Cycle Zero-Integral-Error Current Control for Shunt Active Power Filters

    Get PDF
    [EN] Current control has, for decades, been one of the more challenging research fields in the development of power converters. Simple and robust nonlinear methods like hysteresis or sigma-delta controllers have been commonly used, while sophisticated linear controllers based on classical control theory have been developed for PWM-based converters. The one-cycle current control technique is a nonlinear technique based on cycle-by-cycle calculation of the ON time of the converter switches for the next switching period. This kind of controller requires accurate measurement of voltages and currents in order achieve a precise current tracking. These techniques have been frequently used in the control of power converters generating low-frequency currents, where the reference varies slowly compared with the switching frequency. Its application is not so common in active power filter current controllers due to the fast variation of the references that demands not only accurate measurements but also high-speed computing. This paper proposes a novel one-cycle digital current controller based on the minimization of the integral error of the current. Its application in a three-leg four-wire shunt active power filter is presented, including a stability analysis considering the switching pattern selection. Furthermore, simulated and experimental results are presented to validate the proposed controller.Orts-Grau, S.; Balaguer-Herrero, P.; Alfonso-Gil, JC.; Martínez-Márquez, CI.; Gimeno Sales, FJ.; Segui-Chilet, S.
