Attention-deficit hyperactivity disorder (ADHD) is the most prevalent and impairing neurodevelopmental disorder, with worldwide estimates of 5.29%. ADHD is clinically characterized by hyperactivity-impulsivity and inattention, with neuropsychological deficits in executive functions, attention, working memory and inhibition. These cognitive processes rely on prefrontal cortex function; cognitive training programs enhance performance of ADHD participants supporting the idea of neuronal plasticity. Here we propose the development of an on-line puzzle game based assessment and training tool in which participants must deduce the ‘winning symbol’ out of N distracters. To increase ecological validity of assessments strategically triggered Twitter/Facebook notifications will challenge the ability to ignore distracters. In the UK, significant cost for the disorder on health, social and education services, stand at £23m a year. Thus the potential impact of neuropsychological assessment and training to improve our understanding of the pathophysiology of ADHD, and hence our treatment interventions and patient outcomes, cannot be overstated.

A regional offset (ΔR) from the marine radiocarbon calibration curve is widely used in calibration software (eg CALIB, OxCal) but often is not calculated correctly. While relatively straightforward for known age samples, such as mollusks from museum collections or banded corals, it is more difficult to calculate ΔR and the uncertainty in ΔR for 14C dates on paired marine and terrestrial samples. Previous researchers have often utilized classical intercept methods (Reimer et al. 2002; Dewar et al. 2012, Russell et al. 2011) but this does not account for the full calibrated probability density function (PDF). We have developed an on-line application for performing these calculations for known age, paired marine and terrestrial 14C dates, or U-Th dated corals which is available at http://calib.qub.ac.uk/deltar

This paper investigates the differences in privacy policy functions among 90 online pharmacy websites in nine countries in Europe, Asia and North America. Results from this study show that the majority of websites do have privacy policies, but the level of functional protection of consumers varies widely. Even in those countries where strong privacy laws exist, the level of privacy protection adherence is often very low. Most studies of privacy policy issues have concentrated on websites from developed nations, with few studies of the pharmacy industry. A better understanding of this industry, as well as understanding the differences in privacy policy implementation among developing and developed countries, provides important lessons for both businesses and consumers.

This paper presents MOTION, a modular on-line model for urban traffic signal control. It consists of a network and a local level and builds on enhanced traffic state estimation. Special consideration is given to the prioritization of public transit. MOTION provides possibilities for the interaction with integrated urban management systems.

Online submission and peer review is emerging as the next step forward for many journal publishers in an ever increasing drive to take advantage of technological improvements in transferring data electronically over the internet. The Electronic Submission and PEer REview (ESPERE) project was initiated in 1996 as an electronic Libraries (eLib) initiative of the Higher Education Funding Council for England (HEFCE). Subsequently the project continued as a self-funding group composed of a consortium of learned society and commercial journal publishers intent on utilising the changes in technology to improve the services they provide to their authors as well as cutting their costs and increasing efficiencies.

Il progetto all’interno del quale si è inserita l' attività "La scienza del Mare nelle scuole" è il Progetto Ritmare (La Ricerca Italiana per il Mare). Il progetto Ritmare è un progetto strategico per la ricerca sul mare in Italia, che vuole coniugare le risorse ambientali del mare con l’uso connesso alle attività produttive e allo sfruttamento energetico delle sue risorse, sviluppando tecnologie ed innovazione e, al tempo stesso, promuovendone la sua conoscenza e il rispetto. In tale contesto il progetto propone di sensibilizzare gli studenti delle scuole di primo e secondo grado alle scienze del mare, sperimentando un approccio multidisciplinare che unisca il mondo scientifico e tecnologico a quello didattico, attraverso l'uso di strumenti di comunicazione che vadano dalle forme artistiche ed espressive a quelle prettamente tecnologiche e multimediali.

Like many other higher educat ion schools, ISCAP`s population has grown at a rate of almost 100% in the end of the twentieth century. Its administrative structures were reinforced, but it was not in the same proportion. Face to face with the inability to resolve the problem, the administration decided to implement a computer based system, available in the Internet. In a first stage, in 1997, the system was implemented as a services support. The next stage, in 1999, proposes to increase student services quality. A project that aims to bring student services available on the Internet begins to be developed.

Lan honen egilea Eusko Ikaskuntzaren Asmoz Fundazioaren eta UPV/EHUko Sociología II Sailaren artean antolatzen duten eta Moodle plataforma erabiltzen duen HIZNET on-line graduondokoaren modulu baten irakaslea da. Esperientzia hori abiapuntu, komunikazio honetan hausnarketaren beharra planteatu nahi dugu bereziki bi punturen inguruan: Batetik, unibertsitate alorreko formazioan komunikazio sistema gisa Moodle plataforma bezalako IKT teknologiak erabiltzeak berez hezkuntza praktikaren berrikuntza edota eraldaketa suposatzen ote duen hausnarketa. Bestetik, IKT teknologietan oinarritutako formazio proiektuen eraikuntza sustengatzen dituzten eredu edota paradigmei buruzko hausnarketa.

Introducción: Nutrire® es un programa informático, fruto de tres proyectos de innovación docente de la Universidad de Granada (España), que permite la valoración del estado nutricional mediante a partir de parámetros antropométricos, dietéticos y bioquímicos. Objetivo: El objetivo de este trabajo es presentar los resultados obtenidos de la evaluación global del programa por alumnos y egresados para poder analizar sus puntos fuertes y débiles que sirvan con posterioridad para realizar las modificaciones oportunas. Material y Métodos: Se ha realizado una encuesta anónima a 128 alumnos de 3 titulaciones de grado y 1 de postgrado de la Universidad de Granada. Se incluye 6 preguntas sobre navegabilidad y diseño y 5 sobre contenidos académicos del programa. Asimismo, se han entrevistado a 20 egresados que lo han utilizado en su actividad profesional. Resultados: La puntuación media obtenida en los alumnos fue de 4,1 sobre 5. Como aspectos positivos destacan: facilidad de uso, incorporación de fotografías de alimentos para elegir el tamaño de ración/porción. Como aspectos de mejora señalan: incorporar más fotos de alimentos, el poder instalar el programa para su uso en un ordenador. Según los egresados, el principal punto fuerte es tener reunido en un solo programa los tres aspectos de la evaluación del estado nutricional. Como puntos débiles señalan la falta de algún nutriente, como los azucares, en la base de datos nutricional. Conclusión: Nutrire® es un programa de fácil utilización, muy bien valorada por los alumnos y por los egresados para realizar estudios de evaluación del estado nutricional.
