Por una sociología visual, una trayectoria reciente en la docencia y la investigación cualitativa

La enseñanza de la unidad de aprendizaje Video y Fotografía Etnográficos en la Licenciatura en Sociología dela Universidad Autónoma del Estado de México (uaem), nos ha llevado a clarificar una serie de nudos proble-máticos en torno a la subdisciplina de la sociología visual. Se propone enriquecer su enseñanza considerandosu aportación como una metodología participativa o colaborativa, destacando sus experiencias en el campo delas ciencias sociales como la antropología y la sociología visuales. Se concluye que al igual que otros espaciosacadémicos, se trata de continuar con la enseñanza de las técnicas necesarias para la utilización correcta delos materiales audiovisuales en el campo de la investigación social. Se presentan algunas experiencias al res-pecto y sus dilemas metodológicos y técnicos, con la finalidad de impulsar una sociología visual emergente

Sociología de la juventud: breve estado de la cuestión

Estudiar a la juventud, ha generado ya una generación completa de especialistas y numerosos estudios de caso en México y América Latina. Razones académicas, intelectuales y de orden social han influido en esta generación de juvenólogos. Dada la diversidad de enfoques usados para su estudio, conviene generar un primer estado de la cuestión para evaluar la pertinencia de las perspectivas teóricas que se han presentado al momento. A continuación un breve repaso para abordar la posibilidad de una sociología de la juventud

Sport and maximisation of the subjective perception of wellbeing: A trend analysis of sporting practises at the start of the 21st century.

We have seen a transformation in the development of sporting activities over recent decades. There are a number of social factors behind this. In this article, we report a longitudinal study of sporting activities in Spain between 1995 and 2014 among the population aged 18 and over, including both sexes, examining the social relationships that arise in sporting activities. Our analysis is based on national databases and analysis of trends in sporting activities. It demonstrates the main hypothesis of the study, which is that individual sporting activities have increased compared to group activities with family and friends. We also examine changes in sporting activities depending on the primary relations established in the sport, by sex, age, habitat, occupation, educational level, the form in which the sport is practised, the degree of competition, frequency, the sports facilities used, the type of sport, hours of free time and the subjective sensation of happiness

Subordinated Public Participation Loans for Financing Motorway concessions in Spain.

Budgetary constraints are prompting many governments to encourage private financing of transportation infrastructure through concession contracts. The length and complexity of such contracts often force governments to provide fiscal support in order to increase the attractiveness of concessions. This paper deals with a new public support mechanism for concession contracts, called Subordinated Public Participation Loans (SPPLs), which has been implemented in Spain during the last few years. SPPLs are subordinated loans that may be given by the government to the concessionaire if the latter requests them in the tender. SPPLs are defined in such a way that the increase in interest accrued will reflect the traffic level: the larger the traffic the larger will be the SPPL yield. SPPLs have a twofold goal. First, they increase the financial attractiveness, and hence the feasibility, of concessions contracts. And second, they set up a fairer risksharing approach between the public and the private sector. This paper analyzes the implications of SPPLs in motorway concessions by contrasting the theoretical analysis with the empirical results obtained form the tender of five motorway concessions in Spain. Overall we found that the implementation of this mechanism may be considered a success. In spite of that, we propose some measures that may contribute to improving the SPPL performance in the future

Crimen en el bar

The prohibition of surrogacy contract must be overcome in our Law, as is happening in other neighboring countries (f.e. in Portugal), through reasonable regulation. In front of restrictive criterion of Spanish Supreme Court, the more permissive of Spanish DGRN must be admitted to regulate a contract whose essential goal is the establishment of a humane life. The ECHR considers valid the filiation legally established in a foreign country by a court decision, even if the filiation comes from a surrogacy contract, since rights to private and family life and an identity for children must be saved.La prohibición del convenio de gestación por sustitución debe superarse en nuestro Derecho, como está sucediendo en otros países de nuestro entorno (p.e., en Portugal), a través de una legislación razonable. Frente al criterio restrictivo del Tribunal Supremo español, debe admitirse el más abierto de la DGRN española para regular un convenio que tiene como finalidad esencial la generación de una vida humana. El TEDH considera válida la filiación legalmente establecida en país extranjero por sentencia judicial, incluso si deriva de este convenio, pues deben salvaguardarse los derechos a la vida privada y familiar y a la identidad del niño

On the cutting performance of segmented diamond blades when dry-cutting concrete

The objective of the present study is to analyze and compare the cutting performance of segmented diamond blades when dry-cutting concrete. A cutting criteria is proposed to characterize the wear of the blades by measuring the variation of the external diameter and the weight loss of the blade. The results exhibit the cutting blade SB-A, which has twice the density of diamonds and large contact area, exhibits less wear even though the material removal rate is higher compared with the other two cutting blades. Additionally, the surface topography of the different blades is evaluated to examine the impact of wear depending on the surface profile and the distribution of the diamonds in the blade’s matrix. Large number of diamonds pull-out are found in blades type SB-C, which additionally shows the worst wear resistant capability. As a conclusion, the cutting efficiency of the blade is found to be related to the density of embedded diamonds and the type of the surface profile of the cutting blade after reaching the stop criteria.Peer ReviewedPostprint (published version

Current-induced ductility enhancement of a Magnesium alloy AZ31 in uniaxial micro-tension below 373 K

The size effects in metal forming have been found to be crucial in micro-scale plastic deformation or micro-forming processes, which lead to attenuation of the material’s formability due to the increasing heterogeneity of the plastic flow. The use of an electric field during micro-scale plastic deformation has shown to relieve size effects, enhance the material’s formability, modify the microstructure, etc. Consequently, these electric-assisted (EA) micro-forming processes seem to bring many potential benefits that need to be investigated. Accordingly, here we investigated the influence of an electric field on the size effects to describe the fracture behavior in uniaxial micro-tension tests of an AZ31 alloy with various grain sizes. In order to decouple the thermal-mechanical and microstructure changes, room temperature (RT), oven-heated (OH), air-cooled (AC), and EA uniaxial micro-tension tests were conducted. The size effects contribution on the fracture stress and strain showed a similar trend in all the testing configurations. However, the smallest fracture stresses and the largest fracture strains were denoted in the EA configuration. EBSD examination shows that current-induced dynamic recrystallization (DRX) and texture evolution could be negligible under the studied conditions. The kernel average misorientation (KAM) maps give the larger plastic deformation in the EA specimens due to the reduction of plastic micro-heterogeneity. Finally, the fracture morphology indicates that the current-induced ductility enhancement may be attributed to the arrest of micro-crack propagation and the inhibition of void initiation, growth, and coalescence caused by lattice melting and expansion.Peer ReviewedPostprint (published version
