[EN]Rumenic acid (cis9,trans11-18:2) is the main natural isomer of conjugated linoleic acid (CLA). Rumenic acid has many purported health benefits, but effects of most other CLA isomers are unknown. Typically trans7,cis9-18:2 is the second most abundant CLA isomer, but it co-elutes with rumenic acid on conventional polar gas chromatography (GC) columns, requiring complimentary analysis with silver-ion high performance liquid chromatography (Ag(+)-HPLC). Herein we report a rapid method for analyzing rumenic acid and trans7,cis9-18:2 using a 30 m ionic-liquid GC column. Optimal resolution of the two CLA isomers was at 145 degrees C and analysis of backfat from barley-fed cattle compared well with GC/Ag(+)-HPLC (y =0.978x - 0.031, r =0.985, P <0.001).

[ES] En Historia, la correspondencia epistolar privada, en cuanto medio de comunicación entre personas, es la única fuente documental que revela las interacciones directas, no mediatizadas institucionalmente, entre actores sociales. El artículo explora las posibilidades de esta fuente tanto para el análisis cualitativo e intensivo de las relaciones personales como para reconstruir la “red egocentrada” del receptor de las cartas y llevar a cabo un análisis efectivo de redes sociales, aplicando los métodos y parámetros del “Social Network Analysis”. A partir de dos ejemplos centrados en epistolarios del siglo XVIII, los autores muestran las posibilidades y limitaciones de los análisis cualitativos clásicos y el interés de las aportaciones específicas del análisis de redes egocentradas, abogando por la combinación de ambas metodologías.

In this article we describe the methodology developed for the semiautomatic annotation of EPEC-RolSem, a Basque corpus labeled at predicate level following the PropBank-VerbNet model. The methodology presented is the product of detailed theoretical study of the semantic nature of verbs in Basque and of their similarities and differences with verbs in other languages. As part of the proposed methodology, we are creating a Basque lexicon on the PropBank-VerbNet model that we have named the Basque Verb Index (BVI). Our work thus dovetails the general trend toward building lexicons from tagged corpora that is clear in work conducted for other languages. EPEC-RolSem and BVI are two important resources for the computational semantic processing of Basque; as far as the authors are aware, they are also the first resources of their kind developed for Basque. In addition, each entry in BVI is linked to the corresponding verb-entry in well-known resources like PropBank, VerbNet, WordNet, Levin’s Classification and FrameNet. We have also implemented several automatic processes to aid in creating and annotating the BVI, including processes designed to facilitate the task of manual annotation.

[ES]En la Comunidad Autónoma Vasca se han tomado una serie de decisiones estratégicas materializadas en diversas políticas, planes institucionales e iniciativas con el objeto de integrar, usar e innovar con TIC en las escuelas. Desde iniciativas pretéritas centradas básicamente en la dotación de infraestructuras, pasando por el perfeccionamiento del profesorado, actualmente existe un modelo que intenta unir de facto la política de infraestructura y la formación del los docentes para una utilización eficiente de las TIC. La descripción y el análisis del impacto de las mismas en el entorno escolar es el objetivo de esta investigación. En este estudio se ha llevado a cabo una metodología de corte cualitativo basada en la recogida de ideas, opiniones y valoraciones de políticos, técnicos, directores de centros, así como de profesores mediante entrevistas en profundidad (N=25). Los diferentes agentes educativos entrevistados reconocen que a día de hoy el modelo propuesto que unifica lo tecnológico, lo psicopedagógico y lo organizativo adolece de falta de información eficaz y de financiación impidiendo claramente un impacto real en las escuelas.

[ES] Analizamos en este artículo las ideas y opiniones de los educadores de museos sobre las ventajas e inconvenientes de la integración y uso de las Tecnologías de la Información y de la Comunicación en los museos y espacios de presentación del patrimonio. Para el desarrollo de la investigación, en la que han participado 45 educadores de museos, se ha utilizado la metodología por encuesta, analizando los aspectos a tener en cuenta en su integración y utilización, así como las ventajas e inconvenientes que aportan en la realidad de los museos. Los resultados obtenidos muestran opiniones favorables a la integración y uso de las mismas en estos contextos de aprendizaje y una actitud positiva hacia las tecnologías por parte de los educadores de museos.

Enhancing the handover process in broadband wireless communication deployment has traditionally motivated many research initiatives. In a high-speed railway domain, the challenge is even greater. Owing to the long distances covered, the mobile node gets involved in a compulsory sequence of handover processes. Consequently, poor performance during the execution of these handover processes significantly degrades the global end-to-end performance. This article proposes a new handover strategy for the railway domain: the RMPA handover, a Reliable Mobility Pattern Aware IEEE 802.16 handover strategy "customized" for a high-speed mobility scenario. The stringent high mobility feature is balanced with three other positive features in a high-speed context: mobility pattern awareness, different sources for location discovery techniques, and a previously known traffic data profile. To the best of the authors' knowledge, there is no IEEE 802.16 handover scheme that simultaneously covers the optimization of the handover process itself and the efficient timing of the handover process. Our strategy covers both areas of research while providing a cost-effective and standards-based solution. To schedule the handover process efficiently, the RMPA strategy makes use of a context aware handover policy; that is, a handover policy based on the mobile node mobility pattern, the time required to perform the handover, the neighboring network conditions, the data traffic profile, the received power signal, and current location and speed information of the train. Our proposal merges all these variables in a cross layer interaction in the handover policy engine. It also enhances the handover process itself by establishing the values for the set of handover configuration parameters and mechanisms of the handover process. RMPA is a cost-effective strategy because compatibility with standards-based equipment is guaranteed. The major contributions of the RMPA handover are in areas that have been left open to the handover designer's discretion. Our simulation analysis validates the RMPA handover decision rules and design choices. Our results supporting a high-demand video application in the uplink stream show a significant improvement in the end-to-end quality of service parameters, including end-to-end delay (22%) and jitter (80%), when compared with a policy based on signal-to-noise-ratio information.

Background: Patients with chronic obstructive pulmonary disease (COPD) often experience exacerbations of the disease that require hospitalization. Current guidelines offer little guidance for identifying patients whose clinical situation is appropriate for admission to the hospital, and properly developed and validated severity scores for COPD exacerbations are lacking. To address these important gaps in clinical care, we created the IRYSS-COPD Appropriateness Study. Methods/Design: The RAND/UCLA Appropriateness Methodology was used to identify appropriate and inappropriate scenarios for hospital admission for patients experiencing COPD exacerbations. These scenarios were then applied to a prospective cohort of patients attending the emergency departments (ED) of 16 participating hospitals. Information was recorded during the time the patient was evaluated in the ED, at the time a decision was made to admit the patient to the hospital or discharge home, and during follow-up after admission or discharge home. While complete data were generally available at the time of ED admission, data were often missing at the time of decision making. Predefined assumptions were used to impute much of the missing data. Discussion: The IRYSS-COPD Appropriateness Study will validate the appropriateness criteria developed by the RAND/UCLA Appropriateness Methodology and thus better delineate the requirements for admission or discharge of patients experiencing exacerbations of COPD. The study will also provide a better understanding of the determinants of outcomes of COPD exacerbations, and evaluate the equity and variability in access and outcomes in these patients.
