Cyber risk as a threat to financial stability

Information systems play a critical role in the functioning of financial institutions. While supporting their services and enabling their strategies, underlying vulnerabilities could pose an important source of risk: cyber risk. This may impair financial institutions’ operational capabilities and even threaten their viability. Furthermore, the high level of interconnection and interdependence between the elements of the financial system allows for the contagion of cyber risk among them. Consequently, the materialization of cyber risk in its most extreme form could threaten the stability of the financial system. To address this topic, the article first introduces cyber incidents and their estimated costs, focusing on the financial system. Cyber risk is then considered, together with the main vulnerabilities and threats to cyber security affecting financial institutions. This is followed by a justification of the potential systemic effect of cyber risk on the financial system, supported by the use of theoretical models. Moreover, highlights of the current regulatory framework on cyber risk for financial institutions operating in Spain are also presented. Finally, recommended future lines of work for the improvement of the management of cyber risk in the financial system are discussed

Pixel Features for Self-organizing Map Based Detection of Foreground Objects in Dynamic Environments

Among current foreground detection algorithms for video sequences, methods based on self-organizing maps are obtaining a greater relevance. In this work we propose a probabilistic self-organising map based model, which uses a uniform distribution to represent the foreground. A suitable set of characteristic pixel features is chosen to train the probabilistic model. Our approach has been compared to some competing methods on a test set of benchmark videos, with favorable results.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

La aplicación de las TIC a la enseñanza universitaria y su empleo en la formación en dirección de la producción/operaciones

La evolución de las nuevas tecnologías de la información y de las comunicaciones (TIC) está provocando importantes cambios en numerosos aspectos de nuestra sociedad. La educación no se muestra ajena a esta nueva realidad y está tratando de incorporar todos aquellos elementos de las TIC que mejoren el proceso de enseñanza. Ante esta situación, juzgamos oportuno desarrollar un estudio en el cual pretendemos, como objetivos principales, (1) analizar cómo se están incorporando las TIC a la enseñanza universitaria, (2) determinar los factores que limitan y favorecen dicha incorporación y (3) estudiar el uso de las TIC en la enseñanza de Dirección y Gestión de la Producción/Operaciones en la universidad española.The evolution of the new Information and Communications Technologies (ICT) is implying an important change in several aspects of our society. The education is not indifferent to this new reality, and it is trying to incorporate all the ICT elements that improve the teaching process. Taking this situation into account, we consider appropriate to develop a study in which we want to get, as main objectives, (1) analysing how the ICT are being incorporated to the university teaching, (2) determining the factors that limit and help this incorporation and (3) studying the use of the ICT in the teaching of Production and Operations Management (POM) in the Spanish University

Direct confocal acquisition of fluorescence from X-gal staining on thick tissue sections

X-gal staining is a common procedure used in the histochemical monitoring of gene expression by light microscopy. However, this procedure does not permit the direct confocal acquisition of images, thus preventing the identification of labelled cells on the depth (Z) axis of tissue sections and leading sometimes to erroneous conclusions in co-localization and gene expression studies. Here we report a technique, based on X-gal fluorescence emission and mathematically-based optical correction, to obtain high quality fluorescence confocal images. This method, combined with immunofluorescence, makes it possible to unequivocally identify X-gal-labelled cells in tissue sections, emerging as a valuable tool in gene expression and cell tracing analysis

The effect of verbal instructions in contingency learning depends on the time available to process the cue: evidence in favor of associative models

Much of the research in human contingency learning has tried to dissociate associative and inferential processes. One feature that has been regarded as relevant for these dissociations is the time available to process the cue. A brief presentation of the cue may facilitate the activation of associative processes whereas a long one may favor the activation of inferential processes. The two experiments reported here used a two-phase task. In Phase 1, four different cue-outcome relationships were programmed. In Phase 2, two of these relationships were changed. Participants knew about some of these changes through verbal instructions. The effect of these instructions was measured during Phase 2 in two groups that differed in the time available to process the cue, either 250 or 1500 ms. The results showed that the control of performance produced by verbal instructions differed depending on the time available to process the cue. Only in the 1500 ms group, the verbal instructions were able to affect what it had been learnt during Phase 1. Thus, the results are consistent with the hypothesis that a brief presentation of the cue during Phase 2 facilitates the activation of associative processesUniversidad de Málaga.

Characterisation of the fabrication process of freestanding SU-8 microstructures integrated in printing circuit board in microelectromechanical systems

The characterisation of the fabrication process to develop freestanding SU-8 structures integrated in printing circuit board in microelectromechanical systems (PCBMEMS) technology is presented. SU-8 microcantilevers, microbridges, microchannels and micromembranes have been fabricated following the described procedure. Adherence between FR4 substrate and SU-8 has been examined using the destructive blister method, evaluating the surface energy. Residual thermal stress has also been analysed for this integration and compared when using other substrates. Moreover, an estimation of the copper wet etching with cupric chloride has been performed in order to understand how this isotropic etching affects the geometry of the copper structures. Finally, stiction has been observed and examined, estimating the adhesion energy responsible for this effect

Importancia de la tetanalgesia en la realización de técnicas dolorosas en el recién nacido

Cartel presentado en la Segunda Conferencia Internacional de Comunicación en Salud, celebrada el 23 de octubre de 2015 en la Universidad Carlos III de MadridIntroducción: Hoy en día, es conocido que las estructuras que transmiten el dolor están totalmente desarrolladas antes del nacimiento, al contrario de lo que se pensaba hasta hace no mas de una década. Así pues, hay numerosos estudios que demuestran que los recién nacidos son capaces de sentir dolor e incluso tener una respuesta mas exagerado con respecto a niños de más edad. Con el término tetanalgesia se entiende el efecto analgésico producido en los neonatos cuando están siendo amamantados. Objetivos: Conocer los beneficios del uso de la tetanalgesia en los recién nacidos cuando son sometidos a técnicas dolorosas. Metodología: Estudio observacional sobre datos publicados. Se realiza un revisión bibliográfica con las bases de datos Pubmed, CINAHL, Cochrane y google académico usando las palabras claves: newborn, analgesia, breast feeding, pain. Resultados: Aunque el mecanismo analgésico de la lactancia materna no es bien conocido se cree que se debe a la relación de varios factores tales como el contacto piel con piel, el componente hormonal, el tacto y el gusto azucarado entre otros. La leche materna contiene mayor cantidad de triptófano que la artificial, siendo este un precursor de la melatonina que aumenta la concentración de las endorfinas beta. Según estudios llevados a cabo se ha observado que el amamantamiento es el procedimento mas efectivo frente a otras técnicas analgésicas, mostrando una reducción del tiempo de llanto del 98% en la realizacion de la prueba del talon. Una revisión de la Cochrane concluye que el amamantamiento en la realización de técnicas dolorosas se asocia a menor cambios en la frecuencia cardíaca y en la duración del llanto. Conclusiones: El uso de la lactancia materna en procedimientos dolorosos es el método no farmacológico más eficaz

Masaje perineal en gestantes

Cartel presentadaoen la Segunda Conferencia Internacional de Comunicación en Salud, celebrada el 23 de octubre de 2015 en la Universidad Carlos III de MadridIntroducción: el trauma perineal es una de las complicaciones más frecuentes tras un parto vaginal, que puede estar asociado a una morbilidad a corto y medio plazo; el masaje perineal aumenta la flexibilidad de los músculos perineales, lo que permite extenderse durante el proceso del parto sin que se produzcan desgarros. Objetivos: determinar la influencia del masaje perineal como factor protector frente al trauma perineal. Metodología: estudio observacional sobre documentos publicados. Se realiza una revisión bibliogáfica en las bases de datos Medline y Cochrane, con las siguientes palabras clave: "perineum", "massage" y "perineal trauma"; recogiéndose datos sobre desgarros, incidencia de episiotomía, dolor perineal tras el parto, así como la satisfacción y aceptación sobre el masaje perineal. Resultados: el masaje perineal se asocia a una reducción del 9% del trauma perineal que requiere sutura, así como un 15% menos de probabilidad de sufrir una episiotomía en primíparas, además de reducir en un 32% el dolor perineal a los 3 meses después del parto. En cuanto a la satisfacción de la mujer, el 79% indica que volvería a practicar el masaje y un 87% lo recomendaría a otra gestante. Conclusiones: el masaje perineal anteparto reduce la probabilidad de trauma y dolor perineal continuo. Por tanto, se recomienda informar a las gestantes de los beneficios de la técnica y de cómo realizarla
