What do we know when we know a compulsive buying person? Looking at now and ahead

Over the last few decades, research has seamlessly confirmed the marked multicausal nature of compulsive buying, since variables from different realms (e.g., family, social, and contextual domains) have demonstrated their explanatory capacity. However, it has been personality variables that have, to a greater extent, aroused the interest of researchers, leading to what is now a cumbersome richness of personal constructs of different nature that seem to require some arrangement under integrative frameworks. The proposal by McAdams under the suggestive title of “What do we know when we know a person?” is, in this regard, especially attractive and thought-provoking. McAdams approaches us to the person as a whole by establishing three differentiated levels (dispositional traits, personal concerns or characteristics adaptations, life story), and it will be precisely these levels that will become the structure we will use to address the state of the art on compulsive buyers. The location of the multiple personal variables analyzed at each of the levels with a common grammar will allow us to identify what it is known, as well as what remains to be done in each space. Lastly, suggestions for the future are given, with particular emphasis on advancing our understanding of the person from each of the academic vantage points but also the suitability of designing studies that integrate and/or build bridges between dispositional traits, characteristic adaptations, and life narratives. The hope is that research in the coming years satisfactorily integrates the different visions of the person to achieve a more comprehensive, nuanced portrait of a person with compulsive buying problemsS

A Review of Conceptual Change Research in Science Education

This article describes research done on conceptual change as published in four of the better-known science education journals during a 20-year period, from 1981 to 2001.The present review was focused at identifying three characteristics of that research: a)temporal distribution, b) research topics, and c) methodology: experimental designs and validity. The results show that much research work was carried out, although essential elements of Conceptual Change remained unclear. With respect to the meth-odology, we have evidenced scarce replication of previous studies, and an important number of studies that fall short of desirable validity level

¿Es cierto que el trasplante de médula ósea autóloga mejora el pronóstico de los pacientes con mieloma múltiple?: experiencia de una sola institución en México.

En un periodo de 14 años, en una sola institución, realizamos 30 trasplantes de células hematopoyéticas autólogas a pacientes con mieloma múltiple. La mediana de supervivencia no se ha alcanzado, es mayor de siete años, mientras que la supervivencia a 84 meses fue de 77%. Estos datos son claramente superiores a los obtenidos en un grupo de 23 pacientes con mieloma múltiple tratados en la misma institución con melfalán y prednisona, quienes tuvieron una mediana de supervivencia de 33 meses y una supervivencia a 72 meses de 30%. En nuestra experiencia de una sola institución, la supervivencia a largo plazo en individuos con mieloma múltiple que recibieron un autotrasplante fue claramente superior a la de los pacientes tratados con quimioterapia convencional. El pronóstico a largo plazo de los pacientes con mieloma múltiple mejoró en la Clínica Ruiz de Puebla desde la introducción del trasplante de células hematopoyéticas autólogas para rescatar el tratamiento con quimioterapia a dosis altas

SERS study of different species of p-aminothiophenol adsorbed on silver nanoparticles

In the present work we have focused the discussion on the experimental and theoretical SERS spectra of the organic compound pATP recorded on silver colloids. The huge SERS of pATP on metal substrates is significantly different from its ordinary Raman spectra due to the formation of a new specie namely p,p’ –dimercaptoazobenzene (DMAB). The features of the SERS spectra of pATP are strongly dependent on many factors as i.e. the laser power density or the laser wavelength but there are still important aspects to understand as, for example, the effect of the concentration that has already been studied before by our group. In this case we have analyzed the effect of the concentration at different wavelengths on the SERS spectra of pATP on silver nanoparticles.Universidad de Málaga.

Herramienta de ayuda al análisis forense en vivo de sistemas Linux

Cada día se descubren nuevas vulnerabilidades en los sistemas operativos y, de manera intrínseca, formas de explotar esas vulnerabilidades. El objetivo principal de este proyecto consiste en el análisis, diseño e implementación de una herramienta desarrollada en Java que sirva de ayuda al análisis forense en vivo de sistemas Linux. Para ello presentará, de forma gráfica y en tiempo real, información de la máquina en la que se ejecuta, referente a procesos, conexiones de red, módulos cargados y conexiones SSH establecidas. Como resultado se ha obtenido una aplicación de análisis con las siguientes características: No modificable: está pensada para ser ejecutada desde dispositivos de sólo lectura y así evitar posibles infecciones de malware. Autocontenida: no llama a ejecutables del sistema operativo que pueden estar comprometidos, sino que trabaja con la información del kernel que procesa a través de /proc. Portable: gracias a los dos puntos anteriores conseguimos una herramienta funcional sin necesidad de instalación. _______________________________________________________________________________________________________________________New vulnerabilities and different ways to exploit them on operative systems are discovered every day. The main targets of this project are the analysis, design and implementation of a Java developed tool, which helps us with the forensic analysis of Linux live systems. To accomplish this task, the application will display, graphically and in real time, information about the computer in which the tool is being executed. These data will inform about processes, network connections, kernel loaded modules and established SSH connections. The obtained result is an application with the following features: Unmodificable: the tool must be executed from read-only devices in order to avoid malware attacks. Self-contained: instead of calling system executables that could be already corrupt it works with the kernel information that is processed through /proc. Portable: thanks to the previous features, we get a functional tool that doesn’t need to be installed.Ingeniería Industria

Transparency Policies in European Public Broadcasters: Sustainability, Digitalisation and Fact-Checking

Over the last few years, European public broadcasters have promoted the concept of public service media as one of their main values. To this end, transparency policies have been implemented as a mechanism of corporate projection by strengthening their role as an essential service. The objective of this article is to ascertain the existence of this type of policies among European public broadcasters. To this end, a nominal group was made with 24 experts who were surveyed, thus generating new indicators of transparency and accountability strategies around sustainability and digitalization. The contents of the websites of RTVE (Spain), RTP (Portugal), France TV (France), RAI (Italy), BBC (UK), RTÉ (Ireland), ZDF (Germany), VRT (Belgium), and SVT (Sweden) were also analyzed, paying attention to such indicators and strategies. The main results include the identification of differences on the basis of the ideal models described by Hallin and Mancini; a commitment to credibility (fact-checking) to the detriment of diversity of opinions; and a connection between the political system and the media system, which, preliminarily, determines the level of transparency of these public entitiesThe results of this research are part of the work of the “Equipo de Investigaciones Políticas” (USC). It is also part of the project “Nuevos valores, gobernanza, financiación y servicios audiovisuales públicos para la sociedad de Internet: contrastes europeos y españoles” (2019–2021) financed by the Spanish Ministry of Innovation and Universities (RTI2018-096065-B-I00)S

Etiopatogenia de la halitosis. Revisión

La halitosis o mal aliento es un problema importante dado que puede comprometer la vida de relación de las personas. Es frecuente que se atribuya el origen al estómago o a problemas nasales o pulmonares. No obstante, sabemos que hasta en el 90% de los casos, el origen se encuentra en la cavidad oral, y de forma preponderante debido al acúmulo de placa en el dorso lingual 'cubierta lingual'. La enfermedad periodontal también está directamente relacionada con el mal aliento, de manera que el acumulo de placa, bolsas y/o sangrado son aspectos directamente relacionados con el problema. Desde el punto de vista patogénico, las proteínas de la dieta, las de las bacterias y las de los propios tejidos de la boca, son degradadas por la acción de las proteasas bacterianas hasta aminoácidos. Los aminoácidos ricos en azufre son los máximos responsables del mal aliento. De hecho los tres productos más directamente relacionados son el sulfuro de hidrógeno, el metil mercaptano y el dimetil sulfuro. En la presente revisión repasamos todos estos aspectos y las causas más directamente relacionadas con el problema, revisando igualmente el concepto de halitofobia y pseudohalitosis

Una aproximación integradora al estudio del burnout en los profesores de Universidad

The aim of this paper is to use an integrative approach to identify the main correlates and/or predictors at different levels (personal, psychosocial, occupational and outside the workplace) of the burnout dimensions. The sample consists of 813 university professors. Results from statistical analyses show that there are, indeed, both common and specific predictors for the different facets of the syndrome. Specifically, while social support and optimism are selected to confirm all manifestations of burnout, other factors (work hours per week, time in the profession, hardiness, Type A behavioural pattern, life events, daily hassles) do increase the emergence of differential profiles. Lastly, findings are discussed and the main conclusions are presentedEl objetivo del presente trabajo es identificar, desde un acercamiento integrador, cuáles son los principales correlatos y/o predictores de distintos ámbitos (personal, psicosocial, ocupacional y extralaboral) de las dimensiones del burnout. La muestra está formada por 813 profesores de Universidad. Los resultados de los análisis estadísticos realizados permiten constatar la existencia de predictores comunes y específicos para las facetas del síndrome. Concretamente, mientras se confirma que el apoyo social y el optimismo son seleccionados para explicar todas las manifestaciones del burnout, otros factores (horas de trabajo a la semana, tiempo en la profesión, personalidad resistente, patrón de conducta Tipo A, acontecimientos vitales, contrariedades cotidianas) acentúan la existencia de perfiles diferenciales. Finalmente, se discuten los hallazgos y se presentan las principales conclusionesThis study was possible thanks to a grant given to the project «Análisis de los determinantes psicosociales y biológicos en el estrés laboral de los docentes universitarios» (reference PGIDT99PXI21103A; BSO2000-0475) financed by the Consellería de Educación y Ordenación Universitaria of the Xunta de Galicia and by the Ministerio de Educación y CienciaS

Big Five Personality Traits, Coping Strategies and Compulsive Buying in Spanish University Students

Personality traits and coping strategies have historically been two key elements in the field of health psychology. It is, therefore, striking that there is no study in the field of compulsive buying that integrates the most generic, decontextualized and stable aspects (traits) with those having a more marked processual and dynamic nature, which are closer to goal-based views of human nature (coping strategies). Another weakness of the compulsive buying field is that, despite the confirmed growing increase in compulsive buying in the younger age groups, most studies have been conducted with adult samples. Hence, this study seeks to clarify the role of the Big Five domains and different coping strategies in university students’ compulsive buying. The sample consisted of 1093 participants who were classified as either compulsive buyers or non-compulsive buyers. Both groups were compared regarding sociodemographic variables (gender, age), the Big Five personality traits, and coping strategies through chi-square tests or Student’s t-tests. Besides, a multivariate logistic regression analysis was conducted to determine which of these determinants might play a part in the construction of a risk profile for compulsive buying. The results showed that other than gender (specifically being female), Neuroticism and the use of such coping strategies as problem avoidance and wishful thinking are risk factors that increase the propensity for compulsive buying. The use of active coping strategies such as problem solving, cognitive restructuring and social support, as well as the Conscientiousness dimension are protection factors that decrease the likelihood of becoming a compulsive buyer. Finally, and on the basis of the findings obtained, possible guidelines are given, which, hopefully, may effectively contribute to the prevention of and/or intervention in compulsive buying among young adultsS
