Inter-firm cooperation and innovation: The role of strategic alliances

The relationship between inter-firm cooperation and downscaling, outsourcing and multiple firm strategic alliances is explored conceptually and with data from innovative firms. Downscaling is related to cooperative outsourcing as a significant influence shaping inter- firm relations. Embedding cooperative outsourcing in interfirm strategic alliances is advantageous, particularly for small and medium-size firms. Network structures within alliances are important to consider, however, since they hold the key not only to the division of labour within an alliance, but also to the longevity of the alliance, cooperation, and the relations of trust that pervade transactions.

Diseño de una maquina centrifuga para limpieza de aceites usados

En la arquitectura y desarrollo de este proyecto se mostrara los procesos del sistema en la parte mecánica, electrónica y de software seleccionados para la investigación y solución de la misma. Se planteara el problema, la metodología usada, objetivos, justificación y alcances del proyecto. En la búsqueda de la separación de componentes en elementos líquidos o semilíquidos homogéneos, se ha estudiado diferentes métodos que ayuden a suplir esta necesidad. Al ver como un cuerpo que gira rápidamente sobre un eje tiende alejarse del mismo, se observa la posibilidad utilizar este principio en la separación de mezclas. Se estudió entonces la fuerza centrífuga y la creación de un mecanismo capaz de producir grandes cantidades de esta fuerza con el fin de realizar separaciones en mezclas que hallan en los líquidos. Inicial mente se usó utilidad de las maquinas centrifugas en procesos de tratamientos en las azucareras con el n de extraerse hasta más mínima partícula de la caña de azúcar.Pregrad

Check list of ground-dwelling ant diversity (Hymenoptera: Formicidae) of the Iguazú National Park with a comparison at regional scale

We describe the ant fauna of Iguazú National Park (INP), a region of high biodiversity andendemism in northeastern Argentina that includes the southernmost protected area ofthe Atlantic Forest (AF). Ants were sampled over seven periods from 1998 to 2011 usinga variety of techniques. We also surveyed museum collections and the scientific literatureto obtain additional records of ants from INP. In addition to providing a species list, wecompare ant composition of INP to other sites in the Upper Paraná, Serra do Mar CoastalForest and Araucaria ecoregion of AF. A total of 172 ant species belonging to 56 genera arereported; 56 species are new records for Misiones Province and 39 species are reportedfrom Argentina for the first time. Alto Paraná and Canindeyú departments in Paraguaypresent the most similar ant fauna to INP. Serra da Bodoquena in Brazil and Pilcomayoin Argentina showed higher similarity with the Upper Paraná AF ecoregion, despite thatSerra da Bodoquena is composed of a mix of ecoregions. Ant diversity was lower in UpperParaná than in Serra do Mar Coastal Forest ecoregion. This difference may result fromhigher primary productivity and a greater altitudinal variation in the coastal region.Fil: Hanisch, Priscila Elena.

El relieve, factor para la génesis, desarrollo y gestión del riesgo

Se expone la importancia que tiene el relieve como variable de origen, desarrollo y gestión del riesgo. Asimismo, se presenta la síntesis de algunos desastres ocurridos en el mundo y en México y se señala la vinculación que poseen con el relieve. A su vez, se expone una matriz que involucra las relaciones teóricas entre la exposición física a un desastre y la vulnerabilidad. Al respecto, se discute acerca del sistema de correlación formado por la naturaleza y la sociedad en un vínculo de evolución y dinámica y la relación entre variables que se asocian con el desarrollo y cambio de los geosistemas perturbadores y los de enlace. Finalmente, se ofrece un esbozo idealizado referente a la gestión del riesgo y a sus componentes principales

Interferometric confirmation of "water fountain" candidates

Water fountain stars (WFs) are evolved objects with water masers tracing high-velocity jets (up to several hundreds of km s$^{-1}$). They could represent one of the first manifestations of collimated mass-loss in evolved objects and thus, be a key to understanding the shaping mechanisms of planetary nebulae. Only 13 objects had been confirmed so far as WFs with interferometer observations. We present new observations with the Australia Telescope Compact Array and archival observations with the Very Large Array of four objects that are considered to be WF candidates, mainly based on single-dish observations. We confirm IRAS 17291-2147 and IRAS 18596+0315 (OH 37.1-0.8) as bona fide members of the WF class, with high-velocity water maser emission consistent with tracing bipolar jets. We argue that IRAS 15544-5332 has been wrongly considered as a WF in previous works, since we see no evidence in our data nor in the literature that this object harbours high-velocity water maser emission. In the case of IRAS 19067+0811, we did not detect any water maser emission, so its confirmation as a WF is still pending. With the result of this work, there are 15 objects that can be considered confirmed WFs. We speculate that there is no significant physical difference between WFs and obscured post-AGB stars in general. The absence of high-velocity water maser emission in some obscured post-AGB stars could be attributed to a variability or orientation effect.Comment: To be published in Monthly Notices of the Royal Astronomical Society. 13 pages, 10 figures, 7 tables.

Learning contract, co-operative and flipped learning as useful tools for studying metabolism

Es el Abstract de una comunicación a un congreso internacional sobre educaciónUndergraduate students in Biology identify Metabolic Biochemistry as a particularly difficult subject. This is due to the fact that students need to interconnect properly all the contents of its syllabus throughout their study of the subject in order to get a global insight of the complex regulatory features controlling metabolic pathways within the metabolic network under different physiologic and pathologic conditions, as well as metabolism as a whole. Due to these objective difficulties, a high percentage of our students face the study of this subject as a very hard task beyond their forces and capacities. This perception leads to high rates of premature dropout. In previous years, less than 40% of all the registered students attended the examinations of Metabolic Biochemistry (a subject in the second year of the Degree of Biology at our University). Even worse, less than 25% of our students passed the exams. From the academic year 2015/16 on, we are developing innovative teaching projects (PIE15-163 and PIE17-145, funded by University of Malaga) aimed to increase our student loyalty to the subject (and hence to increase their attendance to exams) and to help them to learn more effectively metabolism and its regulation. These innovative teaching projects are based on the use of several powerful tools: a learning contract and problem-based learning within the framework of group tasks promoting an actual collaborative learning in a flipped classroom. The present communication will show the implementation of the PIE15-163 and PIE17-145 projects and some results obtained from them.This work was supported by Malaga University funds granted to the educational innovation project PIE17-145. The attendance to the END2018 International Conference on Education and New Developments (June 2018, Budapest, Hungary) has received a grant from "I Plan Propio Integral de Docencia.
