Este artículo analiza los efectos de la apertura comercial sobre el mercado de trabajo mexicano. Para ello, se estima la elasticidad de la demanda de trabajo respecto al salario para el sector manufacturero entre 1987 y 2011. El modelo se basó en una ecuación de demanda de trabajo, con una variable adicional como indicador de la apertura comercial, estimada por el método de Arellano-Bover/Blundell-Bond para un sistema dinámico de panel de datos. Los resultados indican que la elasticidad se incrementó con el Tratado de Libre Comercio de América del Norte, lo que tiene importantes implicaciones sobre el mercado de trabajo.

A partir del año 2017, desde el Departamento de Pintura de la Universidad de Granada dentro del Grado en Conservación y Restauración de Bienes Culturales, estamos realizando actividades dirigidas a fomentar la literacidad en el alumnado y recuperar la apreciación por los libros a diferentes edades. Con la incorporación de las nuevas tecnologías y el acceso a contenidos de todo tipo a través de las pantallas, asistimos al paulatino arrinconamiento de la lectura y el empleo de libros, restándoles valor y atención a sus aspectos formales, decorativos y textuales. Es por ello que consideramos fundamental llevar a cabo este tipo de iniciativas que trasladan a las aulas actividades prácticas para impulsar el conocimiento y reconocimiento de los libros a la par que desarrollan habilidades motrices, cognitivas y su creatividad.
Debido a las inusuales circunstancias de este año 2020 y con motivo de la celebración del día del libro el 23 de abril, se han propuesto actividades para poder realizar en casa mediante un archivo digital descargable con contenido visual y audiovisual. Para la divulgación y la exposición de los trabajos realizados se ha utilizado un hashtag y las redes sociales.
La realización de este tipo de actividades está aportando resultados muy positivos y con una alta implicación de los colectivos implicados. Además, consideramos que la implementación de este tipo de actividades de manera regulada en la enseñanza aporta numerosas ventajas como la sensibilización y conocimiento del patrimonio documental, la importancia de su conservación y su defensa.

Introduction: medical doctors, patients and society require the harmonic development of a contemporaneous ethic which responds to the demands of scientific, technical and cultural growth as well as to the socioeconomic and political transformations the present century entails.Objective: to determine the influence of Thomas's disease or Burn-out syndrome in 5 outpatient clinics and 2 dentistry clinics in Pinar del Rio and Consolacion del Sur municipalities during 2011.Material and Method: a descriptive research was carried out considering the opinions of 234 professionals polled and a composed-survey that included 5 questions with 5 options in order to choice the most acceptable ones. Results were processed using descriptive statistics to determine the absolute and relative frequencies represented in tables.Results: the answers were related to the current problems, a crisis in moral values reached 64,5% of the answers of professionals; more than 50% thought this crisis could be avoided in part, they recommended better wage conditions to strengthen motivations, in more than three-fifth parts and 32% considered humanistic formation of professionals should be better to improve the organization of health services. The 45,7% added that user-patient-institution relationship showed imperfections in its organization and recommended to pay attention to the collective analysis of problems to provide and strengthen moral values among the health workers, detecting this when more than 70% of the answers were summed up. Conclusions: despite the demotivation that characterizes Thomas's disease, in view of the confidence in health professionals and the political will that direct the health work toward the excellence the disease can be prevented. ; Introducción: m édicos, pacientes y sociedad precisan del desarrollo armónico de una ética contemporánea que responda a las exigencias de las nuevas relaciones que el desarrollo científico-técnico y cultural impone, al influjo de las profundas transformaciones socioeconómicas y políticas a que el presente siglo reta. Objetivo: determinar la influencia de la Enfermedad de Tomás o síndrome de Burn-out en cinco policlínicos y dos clínicas estomatológicas de Pinar del Río y Consolación del Sur en el mes de marzo del año 2011.

Real-time positron emission tomography (PET) may provide information from first-shot images, enable PET-guided biopsies, and allow awake animal studies. Fully-3D iterative reconstructions yield the best images in PET, but they are too slow for real-time imaging. Analytical methods such as Fourier back projection (FBP) are very fast, but yield images of poor quality with artifacts due to noise or data incompleteness. In this work, an image reconstruction based on the pseudoinverse of the system response matrix (SRM) is presented. w. To implement the pseudoinverse method, the reconstruction problem is separated into two stages. First, the axial part of the SRM is pseudo-inverted (PINV) to rebin the 3D data into 2D datasets. Then, the resulting 2D slices can be reconstructed with analytical methods or by applying the pseudoinverse algorithm again. The proposed two-step PINV reconstruction yielded good-quality images at a rate of several frames per second, compatible with real time applications. Furthermore, extremely fast direct PINV reconstruction of projections of the 3D image collapsed along specific directions can be implemented. ; Part of the calculations in this work were performed in the "Clúster de Cálculo para Técnicas Físicas" funded in part by UCM and in part by UE Regional Funds.

19 pags., 14 figs., 3 tabs. ; The decay of the neutron-rich and was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number above the shell. The -delayed -ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. Three -decay branches of were established, two of which were observed for the first time. Population of neutron-unbound states decaying via rays was identified in the two daughter nuclei of and , at excitation energies exceeding the neutron separation energy by 1 MeV. The -delayed one- and two-neutron emission branching ratios of were determined and compared with theoretical calculations. The -delayed one-neutron decay was observed to be dominant -decay branch of even though the Gamow-Teller resonance is located substantially above the two-neutron separation energy of . Transitions following the decay of are reported for the first time, including rays tentatively attributed to . In total, six new levels were identified in on the basis of the coincidences observed in the and decays. A transition that might be a candidate for deexciting the missing neutron single-particle state in was observed in both decays and its assignment is discussed. Experimental level schemes of and are compared with shell-model predictions. Using the fast timing technique, half-lives of the , and levels in were determined. From the lifetime of the state measured for the first time, an unexpectedly large transition strength was deduced, which is not reproduced by the shell-model calculations. ; M.P.-S. acknowledges the funding support from the Polish National Science Center under Grants No. 2019/33/N/ST2/03023 and No. 2020/36/T/ST2/00547 (Doctoral scholarship ETIUDA).

18 pags., 11 figs., 4 tabs. ; The structure of the doubly magic Sn8250132 has been investigated at the ISOLDE facility at CERN, populated both by the β-decay of In132 and β - delayed neutron emission of In133. The level scheme of Sn132 is greatly expanded with the addition of 68 γ transitions and 17 levels observed for the first time in the β decay. The information on the excited structure is completed by new γ transitions and states populated in the β-n decay of In133. Improved delayed neutron emission probabilities are obtained both for In132 and In133. Level lifetimes are measured via the advanced time-delayed βγγ(t) fast-timing method. An interpretation of the level structure is given based on the experimental findings and the particle-hole configurations arising from core excitations both from the N = 82 and Z = 50 shells, leading to positive- and negative-parity particle-hole multiplets. The experimental information provides new data to challenge the theoretical description of Sn132. ; We acknowledge the support of the ISOLDE Collaboration and the ISOLDE technical teams, and by the European Union Horizon 2020 research and innovation programme under Grant Agreement No. 654002.
