Estudiantes universitarios en riesgo de exclusión social: una aproximación a una realidad social oculta
2017
La reciente recesión y la crisis económica en España han supuesto un duro impacto en las condiciones de vida de la población. En el presente estudio se profundiza en el impacto de la crisis sobre el acceso a los estudios superiores, así como en los comportamientos relacionados con la exclusión social que los estudiantes universitarios han realizado o serían capaces de realizar con el único propósito de costearse su educación. Para ello, 96 estudiantes contestaron voluntariamente una encuesta cuyo objetivo era evaluar su situación sociolaboral y detectar posibles situaciones de riesgo social. La mayor parte de participantes percibía su situación económica como media o baja a pesar de que muc…
Recognition of Trace Element Contamination Using Ficus macrophylla Leaves in Urban Environment
2020
Urban areas are characterized by numerous pollutants emitted by anthropic sources both in the form of solid and gaseous particulates. Biomonitoring is an easy, economical, and accessible approach for the determination of atmospheric pollutants. In this study, we used the leaves of Ficus macrophylla Desf. ex Pers., collected in the city of Palermo (Italy), to determine major and trace elements. Geogenic elements exhibited the highest concentrations, making up 99% of the weight of the analyzed elements (Ca, K, Mg, P, S, Na, Fe, and Al)

Student workload estimation to pass a statistics course in Economics and Business Administration
2007
The convergence process in Higher Education in Europe implies a radical change in the teacher’s practice. One of the fundamental questions in the harmonization process stems from the way credits are allocated by the ECTS (European Credit Transfer System). This article analyzes diverse methodologies for the estimation of student workload, with results regarding the time students need to successfully complete the Descriptive Statistics course in Economics and Business Administration. The obtained estimated time is slightly below the 25-30 hours of credit that are usually established as a reference.

Iodofluorination of alkenes and alkynes promoted by iodine and 4-iodotoluene difluoride
2006
It was found that a mixt. of mol. iodine and 4-iodotoluene difluoride are useful to generate in situ the electrophilic iodine/nucleophilic fluorine (IF) couple that was able to add in a Markovnikov fashion and with prevalent anti-stereoselectivity to various alkenes and alkynes.
Enabling Multimodal Interaction in XPL – the eXtensible Presentation Language
2007
This paper introduces the multimodal extension of the eXtensible Presentation architecture and Language (XPL), a framework aimed at streamlining multi-channel interface design process and enabling full component reuse. XPL incorporates a presentation language based on design pattern paradigm, which supplies a clear distinction between the presentation layer and the corresponding programming logic, promoting contents aggregation and a variety of event handlers described without relying on a (procedural) scripting language. In this paper, the design pattern concept is extended to voice-based interaction, and two verbal design pattern (VeDP) are introduced along to their visual counterparts. T…
