Value Added Contributions of Science Parks the Case of the Barcelona Scientific Park

Science parks are institutions that support the creation and development of high technology-based companies. They are designed to provide value-added services together with high-quality space and facilities and to promote interaction amongst universities, R&D institutions, companies, and markets. Although Spain is among the countries that have been investing heavily in these institutions, there is lack of feedback from the tenant companies' perspective with respect to the value added that they receive from science parks. The objective of this study is to evaluate the services that the Barcelona Science Park offers to its tenants by gathering information from the companies currently located in the park and those that have graduated. By comparing the results obtained from the two groups of companies, incubated and graduated, we examine whether the opinions differ about their appreciation of the services that they benefited from during their stay in the Park than those currently remaining

Similitudes y diferencias en el gasto sanitario de alta tecnología diagnóstica por comunidades autónomas

El objetivo de este trabajo es analizar la variabilidad entre comunidades autónomas en el gasto sanitario en ATD, estudiando si el gasto per cápita en ATD está aumentando y si existe algún colectivo (población de la tercera edad, inmigración, etc.) en el que puedan identificarse unas pautas de consumo diferenciadas a la población en general

Aproximación empírica al análisis del absentismo de los estudiantes universitarios. Estudio del caso de la Facultad de Economía y Empresa (UB)

Los trabajos alrededor del absentismo de los estudiantes en las aulas universitarias no han sido uno de los objetivos preferentes de los autores en materia de investigación educativa. Habitualmente se ha hecho una aproximación a los datos disponibles de absentismo como una variable interviniente o como una variable propia del proceso educativo, pero no como una variable dependiente en el sentido estricto del término

Estrategias implementadas por pequeños productores oaxaqueños para hacer frente a la contingencia sanitaria del SARS-COv-2

La contingencia sanitaria global provocada por el virus SARS-COv2, ocasiono serios estragos económicos en todo el mundo, pero de manera muy especial a la población de las comunidades rurales marginadas. En el estado de Oaxaca, esta situación afectó severamente a las economías locales y de manera especial a los pequeños productores al no tener forma de comercializar sus productos artesanales y requerir de estrategias para hacer llegar su producción al consumidor final. De ahí que el objetivo de capítulo fue conocer que estrategias de recuperación de los territorios post- pandemia implementaron los pequeños productores para encontrar iniciativas de procesos de innovación social para diversificar su actividad productiva y al mismo tiempo seguir conservando el conocimiento tradicional, heredado de forma oral, de generación en generación, que les permita salvaguardar su patrimonio cultural y continuar protegiendo su relación con la naturaleza, ya que la destrucción de sus medios de subsistencia y recursos naturales implica la pérdida de su identidad cultural y de las bases de su subsistencia y de los rasgos identitarios en cada localidad. En el estudio se emplearon métodos cualitativos que incluyeron la observación directa no participante y la realización de entrevistas semiestructuradas a productores de artesanías de carrizo de las comunidades de Santa Cruz Papalutla, y San Juan Guelavía, así como a productores de artesanía de Barro Rojo de la localidad de San Marcos Tlapazola, todas ellas pertenecientes a los Valles Centrales de Oaxaca. Entre los principales resultados se encontró que los pequeños productores tuvieron que implementar mecanismos y procesos de preservación, reproducción y continuidad para conservar el conocimiento tradicional heredado por sus antepasados, y que constituye su patrimonio cultural y rasgo identitario en cada localidad. Sin embargo, dadas las exigencias del mercado de consumo capitalista han tenido que adoptar otros procesos de producción que mediante la innovación social y con apoyo de la capacitación han podido encontrar otras formas de elaboración y diseño de nuevos artículos donde combinan el conocimiento tradicional y la creatividad para ofertar productos que satisfagan las necesidades o exigencias del mercado actual. Entre las conclusiones preliminares se observó que mediante la innovación social abierta pueden ofertar productos diferentes utilizando materiales tradicionales, pero con características y formas diferentes a las que producían las generaciones anteriores, pero tratando de conservar el conocimiento tradicional heredado de sus padres o abuelos. En la actualidad estos productos son más ornamentales, pero también continúan produciendo artículos tradicionales, pero con diferentes dimensiones y tamaños para atender las necesidades del mundo globalizado

MANEJO DE LOS ELECTRODOS DE AGUJAS EN EL LABORATORIO DE EMG. EXPERIENCIA PRÁCTICA DE ENFERMERÍA

In practice, nursing plays an important role in the management of needle electrodes in the electromyography (EMG) lab, particularly in the sterilization and storage. Special attention should be taken with the manipulation of the electrodes, washing hands and using materials in good condition. All these aspects reverberate in the service quality and improve the patient’s care. The main aim of this report is to explain the processes of the use of electrode needles on patients, as well as to describe the precautions, regulations, and care that should be taken with electrodes needles to obtain the best results in the EMG lab. It is important for nurses as well as medical and technical personnel, before using one of the electrodes and its accessories, to wash their hands. To complete actions that avoid mistakes because of the incorrect use of the needle electrodes. Compliance with biosecurity measures to avoid the contraction of diseases, as well as knowing how to adequately operate electrodes needles and the execution of any electromiographic technique, and also bearing in mind the disinfection and sterilization of electromiographic needles in compliance with established procedures should be carried out. The realization of these procedures for the operation of electrode needles, ensures the quality of service and above all prevents that the patient suffers health complications due to a bad procedure.En la práctica, el personal de enfermería participa en el cuidado de los electrodos de agujas para los estudios electrofisiológicos, en especial de su esterilización y almacenamiento adecuado.

Synergy between magneto-rheological fluids and aluminum foams. Prospective alternative for seismic damping

This is the accepted manuscript. Access to the published article can be gained at: http://jim.sagepub.com/cgi/reprint/1045389X15596624v1.pdf?ijkey=SyFHNQwE4XMQqBF&keytype=finiteThis article presents the experimental study of a preliminary investigation of a seismic damper device aimed at improving the behavior of structures when subjected to earthquakes. The damper is the result of a binomial material formed by aluminum foam with pores 1 mm in diameter, wetted by a magnetorheological fluid (MRF). The objective of the present work is to explore the synergy between the two components in a magnetorheological test, and to evaluate the effect of the Al foam pores in the structure buildup of the fluid. The analysis is completed with a compressive test carried out on the MRF-filled foam in the presence of a magnetic field. This kind of test demonstrates that the deformation of the foam for very small loads is limited by the hardening of the fluid because of its MR response. The results of this research suggest that there is a mutual benefit between the components of the device, presumably leading to an enhanced dissipation of vibration energy.Proyectos PE2012-FQM694 (Junta de Andalucía, Spain), FIS2013-47666-C3-1-R (MINECO, Spain), SENER-CONACYT "151496" (UNAM Mexico), CONACYT National Quality Graduate Progra

Platelet-Activating Factor Induces Epigenetic Modifications in Human Mast Cells

UV radiation-induced systemic immune suppression is a major risk factor for skin cancer induction. The migration of dermal mast cells from the skin to the draining lymph nodes has a prominent role in activating systemic immune suppression. UV-induced keratinocyte-derived platelet-activating factor (PAF) activates mast cell migration, in part by upregulating the expression of CXCR4 on the surface of mast cells. Others have indicated that epigenetic mechanisms regulate CXCR4 expression; therefore, we asked whether PAF activates epigenetic mechanisms in mast cells. Human mast cells were treated with PAF, and the effect on DNA methylation and/or acetylation was measured. PAF suppressed the expression of DNA methyltransferase (DNMT) 1 and 3b. On the other hand, PAF increased p300 histone acetyltransferase expression, and the acetylation of histone H3, which coincided with a decreased expression of the histone deacetylase HDAC2. Chromatin immunoprecipitation assays indicated that PAF treatment activated the acetylation of the CXCR4 promoter. Finally, inhibiting histone acetylation blocked p300 upregulation and suppressed PAF-induced surface expression of CXCR4. Our findings suggest a novel molecular mechanism for PAF, activation of epigenetic modifications. We suggest that PAF may serve as an endogenous molecular mediator that links the environment (UV radiation) with the epigenome

Pan-Atlantic analysis of the overlap of a highly migratory species, the leatherback turtle, with pelagic longline fisheries

This is the final version of the article. Available from the publisher via the DOI in this record.Large oceanic migrants play important roles in ecosystems, yet many species are of conservation concern as a result of anthropogenic threats, of which incidental capture by fisheries is frequently identified. The last large populations of the leatherback turtle, Dermochelys coriacea, occur in the Atlantic Ocean, but interactions with industrial fisheries could jeopardize recent positive population trends, making bycatch mitigation a priority. Here, we perform the first pan-Atlantic analysis of spatio-temporal distribution of the leatherback turtle and ascertain overlap with longline fishing effort. Data suggest that the Atlantic probably consists of two regional management units: northern and southern (the latter including turtles breeding in South Africa). Although turtles and fisheries show highly diverse distributions, we highlight nine areas of high susceptibility to potential bycatch (four in the northern Atlantic and five in the southern/equatorial Atlantic) that are worthy of further targeted investigation and mitigation. These are reinforced by reports of leatherback bycatch at eight of these sites. International collaborative efforts are needed, especially from nations hosting regions where susceptibility to bycatch is likely to be high within their exclusive economic zone (northern Atlantic: Cape Verde, Gambia, Guinea Bissau, Mauritania, Senegal, Spain, USA and Western Sahara; southern Atlantic: Angola, Brazil, Namibia and UK) and from nations fishing in these high-susceptibility areas, including those located in international waters.Work in Gabon was financially supported by the Large Pelagics Research Center through National Oceanographic and Atmospheric Agency award no.
