La organización y la gestión en los servicios sociales: el trabajador social en la organización y gestión de los servicios sociales
2010
En este artículo se pretende fomentar la reflexión de las y los trabajadores sociales en temas que no han sido considerados prioritarios entre las funciones a desarrollar desde el trabajo social y que sin embargo son elementos de primera necesidad si queremos hacer perdurar el sistema de servicios sociales, en el que una parte importante de la profesión desarrolla su actividad. Dotar a las unidades, departamentos, servicios, áreas en las que se trabaja de una estructura de organización y gestión que favorezca la consolidación del sistema, poner en valor la gestión del conocimiento, abordar el tema de introducir parámetros de calidad en los servicios que prestamos, establecer procesos y defi…
Pressure dependence of the optical properties of wurtzite and rock-salt Zn1–xCoxO thin films
2007
In this paper we investigate the electronic structure of Zn 1-x Co x O by means of optical absorption measurements under pressure. Thin films of Zn 1-x Co x O with different Co content (from 1 to 30%) were prepared by pulsed laser deposition on mica substrates. Absorption spectra exhibit three main features that are clearly correlated to the Co content in the films: (i) absorption peaks in the infrared associated to crystal-field-split internal transitions in the Co 3d shell, with very small pressure coefficients due to their atomic character; (ii) a broad absorption band below the fundamental edge associated to charge transfer transitions, that exhibit relatively large pressure coefficient…

Structural Properties and Temperature Behaviour of Optical Absorption Edge in Polycrystalline ZnO:X (Cu,Ag) Films
2013
Silver- and copper-doped ZnO lms were prepared by radio-frequency magnetron sputtering on glass substrates. The in uence of dopants content on the structural, morphological properties as well as on evolution of the optical absorption edge was considered. It has been found that Ag- and Cu-doped ZnO lms are characterized by wurtzite crystalline structure with the preferred direction of crystalline orientation (002). The sizes of grains within the lms were found to be dependent on the type of dopant. The temperature evolution of the optical absorption edge is described by the modi ed Urbach rule that re ects polycrystalline nature of the material. The corresponding parameters concerning electr…
Interpretation of the Ni K-edge EXAFS in nanocrystalline nickel oxide using molecular dynamics simulations
2011
Abstract Analysis of atomic structure at the nanoscale is a challenging task, complicated by relaxation phenomena and thermal disorder. In this work, the x-ray absorption spectroscopy at the Ni K-edge was used to address this problem in nanocrystalline NiO (nano-NiO) at 300 K. The analysis of the first two coordination shells using conventional two-shell single-scattering approximation allowed us to determine the expansion of the average lattice but contraction of the Ni―O bonds in the first coordination shell in nano-NiO in comparison with the bulk nickel oxide. The EXAFS signal generated within the first six coordination shells (up to ~ 6.5 A) was successfully interpreted using classical …
The need to grow, learn and develop – how does management affect motivation for professional development?
2018
This article argues that knowledge management and social recognition is important for organisational learning and professional self-esteem in academic libraries. An anonymous survey was issued in 2016 to investigate how library staff’s self-esteem is affected by how they experience their management’s view and overview of their knowledge. The need for what Axel Honneth refers to as social recognition will also be discussed as an important part of how professional self-esteem and work satisfaction is experienced and further how this affects motivation to participate in professional development.
Transition-Edge Sensors for Particle Induced X-ray Emission Measurements
2013
In this paper we present a new measurement setup, where a transitionedge sensor detector array is used to detect X-rays in particle induced X-ray emission measurements with a 2 MeV proton beam. Transition-edge sensors offer orders of magnitude improvement in energy resolution compared to conventional silicon or germanium detectors, making it possible to recognize spectral lines in materials analysis that have previously been impossible to resolve, and to get chemical information from the elements. Our sensors are cooled to the operation temperature (65 mK) with a cryogen-free adiabatic demagnetization refrigerator, which houses a specially designed X-ray snout that has a vacuum tight window…
Tratamiento crítico de la información de estudiantes universitarios desde los entornos personales de aprendizaje
2019
Resumen Partiendo del Proyecto CAPPLE (financiado por el Ministerio español de Economía y Competitividad), en este artículo identificamos las estrategias y las herramientas en red utilizadas por 2054 estudiantes universitarios españoles de último curso para efectuar un tratamiento crítico de la información y gestionar su proceso de aprendizaje. Desde un diseño de investigación no experimental de tipo exploratorio, se ha utilizado un cuestionario validado a través de un triple procedimiento (juicio de expertos, entrevistas cognitivas y estudio piloto) para recoger datos de 75 universidades en España. Los resultados muestran que los futuros profesionales son conscientes de la necesidad de con…
Museos para todos: la traducción e interpretación para entornos multimodales como herramienta de accesibilidad universal
2012
This article is the English version of “Museos para todos. La traducción e interpretación para entornos multimodales como herramienta de accesibilidad universal” by Catalina Jiménez Hurtado, Claudia Seibel & Silvia Soler Gallego. It was not published on the print version of MonTI for reasons of space. The online version of MonTI does not suffer from these limitations, and this is our way of promoting plurilingualism. Audiovisual Translation (AVT) has a scientific responsibility to develop analytical methodologies for the textual phenomenon of multimodality, and for the translation strategies associated with it. At the same time, it should aim to provide studies of universal accessibility wi…
Museums for all: translation and interpreting for multimodal spaces as a tool for universal accessibility
2012
Audiovisual Translation (AVT) has a scientific responsibility to develop analytical methodologies for the textual phenomenon of multimodality, and for the translation strategies associated with it. At the same time, it should aim to provide studies of universal accessibility with a powerful tool for facilitating access to knowledge. This article offers some reflections on the theoretical foundations of AVT and considers how these are projected in the creation of new professional profiles, with specific application to universal accessibility in the museums. La Traducción Audiovisual (TAV) tiene la responsabilidad científica de desarrollar metodologías de análisis para el fenómeno textual de …
