Olympic Games as showcase

In the 1992 Barcelona Olympic Games, besides the country-versus-country typical showdown in the backdrop of Olympics, and the economic and political impulses for the host city, there was a third factor complicating the celebration: rivalry between the Catalan hosts and the Spanish state. By guiding the development of and eventual Olympic projection of national identity, Catalan and Spanish politicians hoped to create a resounding rallying point around which they could unite disparate individuals. The text is made up of: an introduction, five paragraphs on the different political perspective, conclusions, a commentary on the tallying of score and a note section with bibliographical references.

Conversation is the Key : A Short History of Smarthistory.org

Smarthistory.org is a proven, sustainable model for open educational resources in the Humanities. We discuss lessons learned during its agile development. Smarthistory.org is a free, creative-commons licensed, multi-media web-book designed as a dynamic enhancement or substitute for the traditional art history textbook. It uses conversation instead of the impersonal voice of the typical textbook in-order to reveal disagreement, emotion, and the experience of looking. The listener remains engaged with both the content and the interaction of the speakers. These conversations model close looking and a willingness to encounter and engage the unfamiliar. Smarthistory takes the inherent dialogic and multimedia nature of the web and uses it as a pedagogical method. This extendable Humanities framework uses an open-source content management system making Smarthistory inexpensive to create, and easy to manage and update. Its chronological timeline/chapter-based format integrates new contributions into a single historical framework, a structure applicable across the Humanities.

Level shifts in a panel data based unit root test : an application to the rate of unemployment

Several unit root tests in panel data have recently been proposed. The test developed by Harris and Tzavalis (1999 JoE) performs particularly well when the time dimension is moderate in relation to the cross-section dimension. However, in common with the traditional tests designed for the unidimensional case, it was found to perform poorly when there is a structural break in the time series under the alternative. Here we derive the asymptotic distribution of the test allowing for a shift in the mean, and assess the small sample performance. We apply this new test to show how the hypothesis of (perfect) hysteresis in Spanish unemployment is rejected in favour of the alternative of the natural unemployment rate, when the possibility of a change in the latter is considered.

Determinants of the omega-3 index in a Mediterranean population at increased risk for CHD.

The omega-3 index, defined as the sum of EPA and DHA in erythrocyte membranes expressed as a percentage of total fatty acids, has been proposed as both a risk marker and risk factor for CHD death. A major determinant of the omega-3 index is EPA þ DHA intake, but the impact of other dietary fatty acids has not been investigated. In a cross-sectional study on 198 subjects (102 men and 96 women, mean age 66 years) at high cardiovascular risk living in Spain, the country with low rates of cardiac death despite a high prevalence of cardiovascular risk factors, dietary data were acquired from FFQ and blood cell membrane fatty acid composition was measured by GC. The average consumption of EPA þ DHA was 0·9 g/d and the mean omega-3 index was 7·1%. In multivariate models, EPA þ DHA intake was the main predictor of the omega-3 index but explained only 12% of its variability (P,0·001). No associations with other dietary fatty acids were observed. Although the single most influential determinant of the omega-3 index measured here was the intake of EPA þ DHA, it explained little of the former"s variability; hence, the effects of other factors (genetic, dietary and lifestyle) remain to be determined. Nevertheless, the high omega-3 index could at least partially explain the paradox of low rates of fatal CHD in Spain despite a high background prevalence of cardiovascular risk factors.

Efectos inmunológicos del tratamiento psicológico a enfermos de cáncer: ¿qué sabemos?

El diagnóstico y tratamiento del cáncer está asociado a manifestaciones psicológicas negativas tales como estrés, ansiedad, depresión, etc (Carver, Pozo, Harris et al. 1993). En el ámbito de la psiconeuroinmunología, abundan las investigaciones que sugieren un efecto depresor de tales manifestaciones (Cohen y Williamson, 1991) sobre el sistema inmune, o, en cualquier caso, del efecto modulador del estrés sobre la respuesta inmunológica del individuo (Contrada et al. 1990). Diversos modelos psicoinmunológicos (Fig.1) (Greer y Watson, 1985; Temoshock, 1987; Contrada et al. 1990) proponen mecanismos explicativos para dar cuenta de cómo los factores psicológicos pueden afectar a la aparición, desarrollo y recidiva del cáncer. Existe una gran evidencia sobre los efectos que la intervención psicológica ejerce sobre tales manifestaciones, disminuyendo los niveles de ansiedad y depresión, mejorando la calidad de vida de los pacientes, (Luebbert, Dahme, Hasenbring, 2001) y en algunos casos, aumentando las tasas de supervivencia (Fawzy, Fawzy, Huyn et al. 1993). Teniendo en cuenta estas premisas, algunos autores han hipotetizado sobre la posibilidad de aumentar la función inmune a través de la intervención psicológica, hipótesis que, en los últimos años ha generado un interés considerable. Sin embargo, la evidencia disponible ofrece resultados contradictorios, por lo que el objetivo de este trabajo es aportar luz a la controversia existente en este ámbito.

Dinámica de poblaciones de vectores y transmisión del virus Y de la patata en cultivos de pimiento

En 1990 se colocaron 7 trampas horizontales de baldosa verde del tipo utilizado por IRWIN (1980), situadas a la misma altura que el cultivo, en diferentes zonas productoras de pimiento en España: Aranjuez (Madrid), Balboa (Badajoz), Cadreita (Navarra), Mendavia (La Rioja), Torrepacheco (Murcia) y Montañana (Zaragoza). El muestreo abarcó de 18 a 19 semanas en cada localidad. El total de pulgones recolectados durante el período que duró el muestreo fue de 3.186 que corresponden a 29 especies distintas, de los que 1.019 individuos corresponden a la especie Aphis fabae Scopoli (31,98 % del total) y 500 a Aphis gossypii Glover (15,69 %). Otras especies capturadas en menor proporción han sido: Aphis craccivora Koch, Aphis nasturtii Kaltenbach, Diuraphis noxia (Mordvilko) y Brachycaudus spp., entre otras. Se realizaron ensayos de transmisión en laboratorio con el virus Y de la patata (PVY) utilizando las especies más importantes desde el punto de vista del número de capturas realizadas. Se emplearon dos aislados de este virus: uno de ellos obtenido en campo infectando pimiento y que pertenece al patotipo 0 (infecta a «Yolo Wonder» pero no a «Yolo Y») y otro obtenido de patata y perteneciente al grupo N de PVY (patata). Los resultados indican que ambas cepas son transmisibles por Myzus persicae (Sulzer) a pimiento «Yolo Wonder», aunque PVYN se transmite con mucha menor eficiencia. En ensayos de comparación entre distintas especies de vectores en cuanto a la capacidad de transmisión de PVY*, se observa que M. persicae es el más eficaz, seguido de A. gossypii que es el segundo en importancia. Acyrthosiphon pisum Harris fue también capaz de transmitir PVY0, pero con mucha menor eficacia. A la vista de los resultados obtenidos, y a pesar de su gran eficacia de transmisión en condiciones controladas, M. persicae parece tener escasa importancia en cuanto a su capacidad de transmisión de PVY en campo, ya que presenta una baja actividad de vuelo en cultivo de pimiento en todas las localidades muestreadas.

Mercurialis canariensis new for El Hierro Islands (Canary Islands).

Mercurialis canariensis Obbard & S. A. Harris is an endemic plant recently described from the Canary Islands (OBBARD et al., 2006b: 103). This taxon went undetected until recently, having been included within the variability of the Mercurialis annua sensu lato complex (HANSEN & SUNDING, 1993:170; STIERSTORFER & GAISBERG, 2006).

Sustained CTL activation by murine pulmonary epithelial cells promotes the development of COPD-like disease

Chronic obstructive pulmonary disease (COPD) is a lethal progressive lung disease culminating in permanent airway obstruction and alveolar enlargement. Previous studies suggest CTL involvement in COPD progression; however, their precise role remains unknown. Here, we investigated whether the CTL activation receptor NK cell group 2D (NKG2D) contributes to the development of COPD. Using primary murine lung epithelium isolated from mice chronically exposed to cigarette smoke and cultured epithelial cells exposed to cigarette smoke extract in vitro, we demonstrated induced expression of the NKG2D ligand retinoic acid early tran - script 1 (RAET1)as well as NKG2D-mediated cytotoxicity. Furthermore, a genetic model of inducible RAET1 expression on mouse pulmonary epithelial cells yielded a severe emphysematous phenotype characterized by epithelial apoptosis and increased CTL activation, which was reversed by blocking NKG2D activation. We also assessed whether NKG2D ligand expression corresponded with pulmonary disease in human patients by staining airway and peripheral lung tissues from never smokers, smokers with normal lung function, and current and former smokers with COPD. NKG2D ligand expression was independent of NKG2D receptor expression in COPD patients, demonstrating that ligand expression is the limiting factor in CTL activation. These results demonstrate that aberrant, persistent NKG2D ligand expression in the pulmonary epithelium contributes to the development of COPD pathologies.

Teaching cross-cultural competence and CLIL: a CLIL approach in International Relations University Courses

International relations professionals need cross-cultural competence and English language communication skills to function in the international arena (Graddol 1997). English language communication skills are necessary not only to communicate with foreign colleagues (Bocanegra-Valle 2014) but also to access the vast amount of knowledge transmitted in English over the internet (Ku, Zussman 2010). This work reports the use of CLIL and cross-cultural training in the University of Messina International Relations Advanced Degree Program as a method to raise students’ level of English as quickly as possible while giving them the essential intercultural skills for work in the international field. The researchbased course program combined cross-cultural communication training (Storti, 1997; Lewis, 1999; Gannon, 2004, Harris and Moran, 2007; U.S Peace Corps Training Handbook 2012,) and intercultural competence skill development (Bennett, 1998). Two objectives were proposed: 1) develop cross-cultural communication competence; 2) bring students up to a B2 level as fast as possible. The final exam demonstrated significant growth in the areas of cross-cultural competence as well as an increase in European Common Framework level ranging from .5 to 1.0 depending on the student. Students expressed their belief that what they had learned would be useful for their future career. Combining CLIL with intercultural competence building seems to be effective in meeting two objectives: increasing English language fluency and developing cross-cultural communication competence. More research is recommended to further document this method for increasing English communication proficiency while developing interculturally competent international professionals.
