Moore spaces in proper homotopy

Moore spaces are defined in proper homotopy theory. Some results on the existence and uniqueness of those spaces are proven. An example of two non properly equivalent Moore spaces is given

Understanding the effect of place image and knowledge of tourism on residents' attitudes towards tourism and their word-of-mouth intentions: evidence from Seville, Spain

As places are greatly shaped and reshaped by tourism, the way residents perceive their place and their knowledge of tourism gradually transform and become more complex and influential. Drawing on the social exchange and social representations theory, this research aimed to explore the effect residents' place image and knowledge of tourism have on perceived tourism impacts, which were subsequently expected to predict residents' support for tourism development and their word-of-mouth (WOM) intentions. Data were collected from 484 residents in Seville, the third most visited destination in Spain. The findings suggest that place image shaped residents' perceptions of the economic, socio-cultural and environmental impacts, while knowledge of tourism affected only the economic ones. Additionally, place image and support for tourism determined residents' WOM intentions. The study extends current knowledge in mature destinations on the way residents' attitudes are shaped, whereby additional emphasis on place based and resident informed policies is needed

Análisis del diseño organizacional de la Universidad Popular del Cesar - Seccional Aguachica

La Universidad Popular del Cesar, Seccional Aguachica, es el resultado de la necesidad de que en la región del sur del Cesar existiera una oferta de estudios superiores, que permitiera a los egresados del bachillerato en la región continuar sus estudios universitarios, y así ampliar posibilidades para la investigación y el conocimiento, con el ánimo de buscar un equilibrio entre el desarrollo económico y la sostenibilidad del medio ambiente. Sin embargo los desarrollos socioeconómicos y políticos de las regiones, han cambiado con base a las expectativas de la globalización en la economía mundial y las tendencias tecnológicas, por tanto es pertinente y urgente que la Universidad adecue su estructura organizativa de acuerdo a las necesidades del servicio de la educación y sus fines misionales. El análisis del diseño organizacional permite que la Universidad se pueda adecuar a los cambios de la época, para lograr una mejor prestación del servicio a la comunidad y enfrentar el desarrollo con las menores incertidumbres posibles y así darle confiabilidad a nuestros propósitos sociales.The Popular University of Cesar, Sectional Aguachica, is the result of the need for a supply of higher education in the southern region of Cesar, which would allow graduates of the baccalaureate in the region to continue their university studies, and thus expand possibilities for research and knowledge, with the aim of finding a balance between economic development and environmental sustainability. However, the socioeconomic and political developments of the regions have changed based on the expectations of globalization in the world economy and technological trends, therefore it is pertinent and urgent that the University adapt its organizational structure according to the needs of the service. Of education and its missionary purposes. The analysis of organizational design allows the University to adapt to the changes of the time, to achieve a better service to the community and face development with the lowest possible uncertainties and thus give reliability to our social purposes

Performance improvement of low-temperature a-SiGe:H thin-film transistors

This paper presents the study of an interface preparation procedure in the source/drain regions of the active layer, prior to deposit the n+ a-Ge:H contact layer in the fabrication process of low-temperature a-SiGe:H thin-film transistors. The devices were fabricated on corning 1737 substrates at 200 °C. The improvement in metal–semiconductor interface by the interface preparation procedure was demonstrated. This interface improvement translates in higher mobility and better values of off-current, on/off-current ratio, subthreshold slope and threshold voltage

First lattice QCD estimate of the g_{D^* D pi} coupling

We present the results of the first lattice QCD study of the strong coupling g_{D^* D pi}. From our simulations in the quenched approximation, we obtain g_{D^* D pi} = 18.8 +/- 2.3^{+1.1}_{-2.0} and hat(g)_c = 0.67 +/- 0.08^{+0.04}_{-0.06}. Whereas previous theoretical studies gave different predictions, our result favours a large value for hat(g)_c. It agrees very well with the recent experimental value by CLEO. hat(g) varies very little with the heavy mass and we find in the infinite mass limit hat(g)_infinity = 0.69(18).Comment: 24 pages, 7 figures; references added, corrected typos, Comments added about the continuum limi

High Quality SiO₂ Obtained From diluted SOG for Low Temperature TFT Fabrication Process

Currently, the flexible electronics research field is of high interest because of the development of low cost products, such as solar cells and LCDs. Low temperature deposition processes are required in order to use flexible substrates. Nevertheless, the performance of the electronic devices built at temperatures below 350 °C is not as good as in CMOS technology. Thus, physical and electrical properties of semiconductor and insulator materials deposited at these low temperatures must be improved. In this work, characterization of SiO₂ annealed at 200°C obtained from diluted Spin On Glass (SOG) is presented. The optical and electrical characterization showed that the refractive index (n) and dielectric constant (k) values are similar to those of thermally grown SiO₂. TFTs based on a-SiGe:H were fabricated to demonstrate the quality of the dielectric here obtaine

We report a new locality for Espadarana prosoblepon (Boettger, 1892) in a riparian forest on the western slopes of the Cordillera Central of Colombia, which extends its distribution ca. 100 km S from previous known records

Herramientas de infraestructura como código: Ansible, Terrafom, Chef, Puppet

Infrastructure tools such as code (IaC) allow the tasks performed by IT departments to be automated quickly and dynamically through the use of scripting languages, which allow managing, creating, manipulating and distributing multiple large-scale computing resources within of Cloud Computing infrastructure. Infrastructure tools such as Ansible code, Terrafom, Chef, Puppet, generate a virtual representation of all the physical and scalable infrastructure of a Cloud Computing and Data Center platform, making it easy to program and dynamic.Las herramientas de Infraestructura como código (IaC) permiten automatizar las tareas realizadas por los departamentos de IT de forma rápida y dinámica mediante el uso de lenguajes de programación de scripts, que permiten administrar, crear, manipular y distribuir múltiples recursos informáticos a gran escala dentro de una infraestructura de Cloud Computing.

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.
