Los procesos de integración de personas inmigrantes : límites y nuevas aportaciones para un estudio más integral

Los procesos de integración de personas inmigrantes es una cuestión de compleja conceptualización y de amplia discusión tanto en el ámbito de la política pública como desde la academia. El pretendido consenso europeo sobre la integración se ha quedado únicamente en el cómodo discurso de la bidireccionalidad y el estudio de los procesos de integración en las sociedades de acogida se ha planteado siempre desde parámetros cuantificadores y objetivistas que no son capaces de aprehender la diversidad de los mismos. Además el estudio de la integración ha pasado por alto la importancia que tiene la sociedad de origen y el vínculo que las perso - nas inmigrantes conservan con éstas, centrándose únicamente en la sociedad receptora como lugar de integración. En este trabajo propongo la ampliación de la mirada sobre la integración incorporando la perspectiva de origen y la subjetividad de la persona inmigrante como actor con capacidad de cuestionar, decidir y transformar las pautas y contextos en los que se produce la integración.The integration process of immigrants is a complex issue of conceptualization and extensive discussion both in the field of public policy and from the academia. The alleged European consensus about integration has only been in the comfortable speech of bidirectionality and the study of the integration process in host societies has been raised ever from quantifier and objectivist parameters that are not able to grasp the diversity of thereof. Furthermore, the study of integration has overlooked the importance of the society of origin and the link that immigrants remain with them, focusing only on the host society as a place of integration. In this paper I propose the extension of the look on the integration by incorporating the perspective of origin and the subjectivity of the immigrants as an actor with the capacity to question, decide and change the patterns and contexts in which integration occurs

Estudio analítico de los documentos de trabajo del parlamento europeo

El Parlamento Europeo es la institución representante de los intereses civiles en el marco de la Unión Europea. Como tal pero sobre todo, como único órgano de carácter asambleístico comunitario que es, genera series documentales con características muy definidas. El escaso número de estudios realizados en nuestro país sobre la documentación de trabajo de la Eurocámara dificulta no sólo la labor de los investigadores que han de enfrentarse, de forma ineludible, al complejo mapa documental del PE independientemente de cual sea el aspecto que sobre esta institución vayan a examinar sino la del conjunto de profesionales que desde el ámbito universitario intentamos acercar el repertorio bibliográfico-documental de la Unión a nuestros alumnos. Por todo ello, creemos oportuno ofrecer un análisis descriptivo de los principales documentos generados por la institución que tienen como fin ser presentados, debatidos y adoptados/rechazados por el hemiciclo eurocomunitario.The European Parliament is the institution which represents civilian interests within the framework of the European Union. As such, but above all, on account of its being the only organ of an assembly type nature for the community, it generates series of documents of very defined characteristics.The reduced number of studies carried out in our country concerning the working documents of the European Parliament causes difficulties, not only to research workers, who inevitably have to come to grips with the complex informational map of the European Parliament whatever aspect of this institution they may study, but also to all the professionals who, in the university sphere, attempt to bring our students into contact with the bibliographic-documentary repertory of the Union.These are the reasons for offering a descriptive analysis of the principal documents generated by the institution which are to be presented, debated and either approved or rejected by the European Parliament

Statistical methodology and software to analyse oscillatory signals with applications to biology

Many physiological and biological phenomena, such as menstrual cycles (Draper et al. (2018)), reproductive activity (Simonneaux and Bahougne (2015), Caba et al. (2018)), cell cycle (Liu et al. (2017)) or circadian biology (Hughes et al. (2009), Zhang et al. (2014), Andreani et al. (2015), Seney et al. (2019)), are governed by oscillatory systems consisting of numerous signals that exhibit rhythmic patterns over time. For example, the circadian clock is a molecular pacemaker that orchestrates daily functional activity including metabolic state, endocrine activity or neural excitability. Genes involved in those processes that exhibit rhythmic expression patterns along ~24-hour periods are called circadian genes. The study of such signals with temporal rhythmic patterns, and how these patterns change under different conditions, is called chronobiology. Chronobiology has been an active area of research during the past two decades, with major impact on treating cardiovascular disorders like hypertension (Halberg et al. (2013)), detecting genes associated with neurodegenerative disorders (Li et al. (2013)) or depression (Chauhan et al. (2017)), and improving the effectiveness of cancer treatments (Chan et al. (2017)). For instance, Haus (2009) demonstrated that the timing of radiation according to host and/or tumour rhythms improves the toxic/therapeutic ratio of the treatment. These and other findings in biomedical sciences have increased interest in chronobiological experiments. From a statistical point of view, the analysis of rhythmic signals ( ) in chronobiology has several challenges because of: (a) displays a wide variety of rhythmic patterns over time, which are not exactly sinusoidal or even symmetric (Koren£i£ et al. (2012), Zhang et al. (2014), Rueda et al. (2019)); (b) the density of the time points and the number of periods of data is usually very small (Panda et al. (2002), Hughes et al. (2007, 2009), Yang and Su (2010)); (c) the intrinsic circular nature of data from oscillatory systems; (d) the vari- 1 ability in time course expression data due to noisy nature of the data; (e) in some applications, the temporal order among samples may be unknown. For these reasons, standard time series or Fourier models are not convenient for the analysis of chronobiological rhythms (Elkum and Myles (2006), Wijnen et al. (2006), Leise (2013)). Models based on parametric functions of time, such as Cosinor, have been proposed in chronobiology to model these patterns (Tong (1976), Cornelissen (2014)). The main drawback of these approaches is that such parametric functions are too rigid, as signals in oscillatory systems very often exhibit asymmetric patterns. There are several commonly encountered problems in chronobiology. The main problem to solve in this context is rhythmicity detection as not all patterns observed in an oscillatory system display rhythmic patterns. For a given signal ; rhythmicity detection can be formulated as the following hypothesis test: H0 : is a flat signal (1.1) H1 : is rhythmic signal. This problem has been studied extensively in literature, existing a wide variety of procedures to address it including, among others, those based on sinusoidal curve fitting (Liu et al. (2004), Straume (2004), Cornelissen (2014)), autocorrelation (Levine et al. (2002)) or Fourier analyses (Wichert et al. (2004)). Some non-parametric approaches, such as JTK_Cycle (JTK) (Hughes et al. (2010)) and RAIN (Thaben and Westermark (2014)), based on Jonckheere- Terpstra test and Kendall's tau correlation, are widely employed by biologists. However, these two latter approaches do not detect asymmetric rhythmic patterns properly. A fundamental assumption made in the above discussion is that the time corresponding to each biological sample is known. However, in many instances, such as when dealing with samples obtained from human cadavers (Li et al. (2013), Seney et al. (2019)) or human organ biopsies, (Lamb et al. (2011), Bossé et al. (2012)), the exact time corresponding to each biological sample may be unknown. In such cases, one needs to first estimate or determine the time associated with each sample before investigating rhythmicity. This problem, known as temporal order estimation, is other crucial issue in chronobiology. Some recent procedures to cope with this problem are Oscope (Leng et al. (2015)) and CYCLOPS (Anafi et al. (2017)). Oscope was specifically designed to recover cell cycle dynamic, and it is only applicable in single cell RNA-Seq experiments. CYCLOPS is far from a mathematical close-fitting formulation. It is based on a neural network framework (which is like a black box) and uses additional rhythmicity information which is not always available. In addition to the major rhythmicity issues mentioned above, other interesting questions related to the analysis of oscillatory signals, such as peak time 2 estimation or rhythm-pattern comparisons, deserve consideration. For instance, when dealing with circadian genes, time peak estimation reveals crucial information for biologists about the timings at which genes' biological function is carried out. The main motivation of this thesis was to solve appealing rhythmicity questions specifically related to the analysis of circadian gene expression. In particular, the starting problem of this thesis was to identify among the several thousand of genes registered in a genetic study, those that display rhythmic expression patterns.Departamento de Estadística e Investigación OperativaDoctorado en Matemática

Responsabilidad del estado en casos de contagio de infecciones intrahospitalarias

Artículo de investigaciónEl presente artículo presenta un análisis del escenario de contagio de pacientes en clínicas u hospitales públicos y la estructuracion de la responsabilidad del Estado en estos casos, basado en una metodología de análisis jurisprudencial y doctrinal que permita determinar el título de imputación y los casos que se han presentando en Colombia. El riesgo de contagio de infecciones en el ámbito intrahospitalario no se puede eliminar; cumplir los protocolos, si bien es cierto, disminuye tangiblemente la posibilidad de la ocurrencia de este hecho, no garantiza que no se pueda presentar esta situación, en ese sentido se hace nacesario realizar una análisis de la responsabilidad que puede surgir cuando dicho riesgo se llegue a materializar. Así entonces surge en interrogante ¿Cómo se estructura la responsabilidad del estado en los casos de contagio de infecciones intrahospitalarias? A partir del desarrollo de este artículo de reflexión se exponen los posibles escenarios que se pueden presentar en el caso de contagio de una infección intrahospitalaria a un paciente, y este cause daños graves a su salud o incluso la muerte del mismo.36 p.1.

Preparing for generation Z:how can technology enhanced learning be firmly embedded in our students' learning experience? A case study from Abertay University

Abertay is a relatively small, modern university (undergraduate population of around 4000) with a wide portfolio and a diverse student population. Around 35% of our students are direct entry from local partner colleges to years 2 and 3 of our programmes and a significant number are first generation higher education within their families. As such, partnership working with colleges and support to aid student transitions are key aspects of Abertay’s provision. Since 2013/14, the university has developed and implemented a new Teaching and Learning Enhancement strategy that has catalysed wholescale transformation across the institution. This paper provides an overview of technology enhanced learning at the university with the drivers for change being to the quality of our students' learning experience, improve student retention and progression and enhance learners’ engagement

A Finite Element Numerical Algorithm for Modelling and Data Fitting in Complex Systems

Numerical modelling methodologies are important by their application to engineering and scientific problems, because there are processes where analytical mathematical expressions cannot be obtained to model them. When the only available information is a set of experimental values for the variables that determine the state of the system, the modelling problem is equivalent to determining the hyper-surface that best fits the data. This paper presents a methodology based on the Galerkin formulation of the finite elements method to obtain representations of relationships that are defined a priori, between a set of variables: y = z(x1, x2,...., xd). These representations are generated from the values of the variables in the experimental data. The approximation, piecewise, is an element of a Sobolev space and has derivatives defined in a general sense into this space. The using of this approach results in the need of inverting a linear system with a structure that allows a fast solver algorithm. The algorithm can be used in a variety of fields, being a multidisciplinary tool. The validity of the methodology is studied considering two real applications: a problem in hydrodynamics and a problem of engineering related to fluids, heat and transport in an energy generation plant. Also a test of the predictive capacity of the methodology is performed using a cross-validation method
