La Accesibilidad universal y el diseño para todos: los ejes determinantes de las políticas de igualdad de oportunidades III

Capítol del llibre "Tratado sobre la discapacidad", R. De Lorenzo, L. Cayo Pérez Bueno. Navarra: Thomson Aranzadi,2007. Planteja el significat dels conceptes "Accessibilitat Universal", que és fonamentalment la condició que han de complir els entorns, processos, bens, productes i serveis, així com els objectes o instruments, eines i dispositius, per a ser comprensibles, utilitzables i practicables per a totes les persones en condicions de seguretat i comoditat i de la manera més autònoma possible.. Això pressuposa el "Disseny per a tothom" i s'entén que sense perjudici dels ajustos raonables que s'hagin d'adoptar.

La Accesibilidad universal en los municipios: guía para una política integral de promoción y gestión

Conscientes de las complejidades que presenta la organización administrativa local y la diversidad que caracteriza a los Ayuntamientos de España, y lejos de querer establecer fórmulas mágicas o generalizar soluciones, con esta Guía se pretende aportar ideas útiles mediante propuestas y algunos ejemplos; con ella se quiere ayudar a promover distintas intervenciones a favor de la accesibilidad en los municipios. En este sentido, esta Guía pretende ser soporte para desarrollar una nueva etapa de intervención municipal en accesibilidad, que vaya más allá de la mera supresión de barreras y se prevenga su creación. Las medidas que se desarrollan son posibles vías para que los gobiernos locales puedan gestionar y promocionar de forma eficaz la accesibilidad en el municipio y así establecer una base sobre la cual todos los ciudadanos puedan desarrollar sus libertades individuales plenamente.

Guía para el diseño e implementación de un master en accesibilidad universal. La aplicación del diseño para todos en entornos, productos y servicios

Esta Guía nace con la intención de impulsar en esta situación poco favorable el desarrollo del mencionado curso de postgrado en la universidad española. En ese sentido, pretende ser un recurso a utilizar por el profesorado universitario y el grupo de expertos en accesibilidad que constituya el futuro equipo docente de esta iniciativa formativa, como punto de partida para el necesario proceso de concreción curricular que tendrán que realizar. Queremos destacar aquí que esta guía no se concibe, por tanto, como el programa de un Master en accesibilidad Universal, aunque incluye a modo de ejemplo una propuesta concreta, sino como un conjunto de recursos a utilizar para elaborarlo, respetando así el principio de autonomía universitaria y docente en el que creemos firmemente.

Prevalence of frailty indicators and association with socioeconomic status in middle-aged and older adults in a swiss region with universal health insurance coverage : a population-based cross-sectional study

Frailty prevalence in older adults has been reported but is largely unknown in middle-aged adults. We determined the prevalence of frailty indicators among middle-aged and older adults from a general Swiss population characterized by universal health insurance coverage and assessed the determinants of frailty with a special focus on socioeconomic status. Participants aged 50 and more from the population-based 2006-2010 Bus Santé study were included (N = 2,930). Four frailty indicators (weakness, shrinking, exhaustion, and low activity) were measured according to standard definitions. Multivariate logistic regressions were used to determine associations. Overall, 63.5%, 28.7%, and 7.8% participants presented no frailty indicators, one frailty indicator, and two or more frailty indicators, respectively. Among middle-aged participants (50-65 years), 75.1%, 22.2%, and 2.7% presented 0, 1, and 2 or more frailty indicators. The number of frailty indicators was positively associated with age, hypertension, and current smoking and negatively associated with male gender, body mass index, waist-to-hip ratio, and serum total cholesterol level. Lower income level but not education was associated with higher number of frailty indicators. Frailty indicators are frequently encountered in both older and middle-aged adults from the Swiss general population. Despite universal health insurance coverage, household income is independently associated with frailty.

Universal banking, competition and risk in a macro model

A stylized macroeconomic model is developed with an indebted, heterogeneous Investment Banking Sector funded by borrowing from a retail banking sector. The government guarantees retail deposits. Investment banks choose how risky their activities should be. We compared the benefits of separated vs. universal banking modelled as a vertical integration of the retail and investment banks. The incidence of banking default is considered under different constellations of shocks and degrees of competitiveness. The benefits of universal banking rise in the volatility of idiosyncratic shocks to trading strategies and are positive even for very bad common shocks, even though government bailouts, which are costly, are larger compared to the case of separated banking entities. The welfare assessment of the structure of banks may depend crucially on the kinds of shock hitting the economy as well as on the efficiency of government intervention.

Desarrollo de biomarcadores del grado de exposición y activación para la evaluación de la neurotoxicidad de la MDMA en humanos

La 3,4-Metilendioximetanfetamina (MDMA, éxtasis) es un derivado anfetamínico sintético ampliamente usado como droga recreativa, que produce neurotoxicidad serotonérgica en animales y posiblemente también en humanos. El mecanismo subyacente de neurotoxicidad, incluye la formación de especies reactivas de oxigeno (ROS), pero la fuente de generación de estos es un punto de controversia. Se postula que la neurotoxicidad inducida por la MDMA es mediada por la formación de metabolitos bioreactivos. Específicamente, los metabolitos primarios de tipo catecol, la 3,4- dihidroximetanfetamina (HHMA) y la 3,4-dihidroxianfetamina (HHA), que luego dan lugar a la formación de conjugados con el glutatión y la N-acetilcisteína, y que conservan la capacidad de entrar en el ciclo redox y presentan neurotoxicidad serotonérgica en ratas. Aunque la presencia de dichos metabolitos se demostró recientemente en microdialisados de cerebros de ratas, su formación en humanos no se ha reportado aun. Este trabajo describe la detección de N-acetil-cisteína-HHMA (NAC-HHMA) y N-acetil-cisteína-HHA (NAC-HHA) en orina humana de 15 consumidores recreacionales de MDMA (1.5 mg/kg) en un entorno controlado. Los resultados revelan que en las primeras 4 horas después del consumo de MDMA aproximadamente el 0.002% de la dosis administrada es recuperada como aductos tioéter. Los polimorfismos genéticos en la expresión de las enzimas CYP2D6 y COMT, que en conjunto son las principales determinantes de los niveles estables de HHMA y HHA, posiblemente expliquen la variabilidad interindividual observada en la recuperación de la NAC-HHMA y la NAC-HHA en orina. Resumiendo, por primera vez se demuestra la formación de aductos tioéteres neurotóxicos de la MDMA en humanos. Estos resultados apoyan la hipótesis de que la bioactivación de la MDMA a metabolitos neurotóxicos es el mecanismo relevante para la generación de la neurotoxicidad en humanos.

Optimal Universal and Categorical Benefits with Classification Errors and Imperfect Enforcement

We determine he optimal combination of a universal benefit, B, and categorical benefit, C, for an economy in which individuals differ in both their ability to work - modelled as an exogenous zero quantity constraint on labour supply - and, conditional on being able to work, their productivity at work. C is targeted at those unable to work, and is conditioned in two dimensions: ex-ante an individual must be unable to work and be awarded the benefit, whilst ex-post a recipient must not subsequently work. However, the ex-ante conditionality may be imperfectly enforced due to Type I (false rejection) and Type II (false award) classification errors, whilst, in addition, the ex-post conditionality may be imperfectly enforced. If there are no classification errors - and thus no enforcement issues - it is always optimal to set C>0, whilst B=0 only if the benefit budget is sufficiently small. However, when classification errors occur, B=0 only if there are no Type I errors and the benefit budget is sufficiently small, while the conditions under which C>0 depend on the enforcement of the ex-post conditionality. We consider two discrete alternatives. Under No Enforcement C>0 only if the test administering C has some discriminatory power. In addition, social welfare is decreasing in the propensity to make each type error. However, under Full Enforcement C>0 for all levels of discriminatory power. Furthermore, whilst social welfare is decreasing in the propensity to make Type I errors, there are certain conditions under which it is increasing in the propensity to make Type II errors. This implies that there may be conditions under which it would be welfare enhancing to lower the chosen eligibility threshold - support the suggestion by Goodin (1985) to "err on the side of kindness".

Integer Programming on Domains Containing Inseparable Ordered Paris

Using the integer programming approach introduced by Sethuraman, Teo, and Vohra (2003), we extend the analysis of the preference domains containing an inseparable ordered pair, initiated by Kalai and Ritz (1978). We show that these domains admit not only Arrovian social welfare functions \without ties," but also Arrovian social welfare functions \with ties," since they satisfy the strictly decomposability condition introduced by Busetto, Codognato, and Tonin (2012). Moreover, we go further in the comparison between Kalai and Ritz (1978)'s inseparability and Arrow (1963)'s single-peak restrictions, showing that the former condition is more \respectable," in the sense of Muller and Satterthwaite (1985).
