Working memory effects in speeded RSVP tasks
The present paper examines the effects of memory contents and memory load in rapid serial visual presentation (RSVP) speeded tasks, trying to explain previous inconsistent results. We used a one target (Experiment 1) and a two-target (Experiment 2) RSVP task with a concurrent memory load of one or four items, in a dual-task paradigm. A relation between material in working memory and the target in the RSVP impaired the identification of the target. In Experiments 3 and 4, the single task was to determine whether any information in memory matched the target in the RSVP, while varying the memory load. A match was detected faster than a non-match, although only when there was some distance between targets in the RSVP (Experiment 4). The results suggest that memory contents automatically capture attention, slowing processing when the memory contents are irrelevant to the task, and speeding processing when they are relevant.Spain.

Raúl Roa y Jorge Mañach. Actualización de una polémica
Given his strong temperament, Raúl Roa, the Chancellor of Dignity, did not usually miss a chance to point out statements considered unjust or harmful to the revolutionary interests, by fighting it with his pen and speech. In his polemic debates, he had in his favor his brilliant and sharp intelligence and a vast culture, as well as an extraordinary ability to find the essential and defining edges of the problem under debate, and to project them with solid and compelling arguments. In his polemic with Jorge Mañach, a Cuban intellectual who worked between the 1920s and 1960s, his peculiar style is highlighted, in which one can appreciate, togetherwith a polished and educated language, popular expressions that give his prose a rich Cuban flavor.Dado su fogoso temperamento, Raúl Roa, el Canciller de la Dignidad, no solía dejar pasar planteamiento alguno que fuese considerado injusto o lesivo a los intereses revolucionarios, sin combatirlo con su pluma en ristre. En sus debates polémicos, tenía a su favor su brillante y aguda inteligencia, y una amplia y profunda cultura, además de una extraordinaria habilidad para encontrar las aristas esenciales y definitorias del problema objeto de debate, y proyectarlas con sólidos y contundentes argumentos. En la polémica con Jorge Mañach, intelectual cubano que despliega su labor entre los años 20-60, queda a relieve su peculiar estilo, donde se aprecia, junto a un lenguaje pulido y culto, expresiones populares que le dan a su prosa un criollísimo sabor

Liver Cholesterol Overload Aggravates Obstructive Cholestasis by Inducing Oxidative Stress and Premature Death in Mice
Nonalcoholic steatohepatitis is one of the leading causes of liver disease. Dietary factors determine the clinical presentation of
steatohepatitis and can influence the progression of related diseases. Cholesterol has emerged as a critical player in the disease and
hence consumption of cholesterol-enriched diets can lead to a progressive form of the disease. The aim was to investigate the impact
of liver cholesterol overload on the progression of the obstructive cholestasis in mice subjected to bile duct ligation surgery. Mice
were fed with a high cholesterol diet for two days and then were subjected to surgery procedure; histological, biochemical, and
molecular analyses were conducted to address the effect of cholesterol in liver damage. Mice under the diet were more susceptible
to damage. Results show that cholesterol fed mice exhibited increased apoptosis and oxidative stress as well as reduction in cell
proliferation. Mortality following surgery was higher in HC fed mice. Liver cholesterol impairs the repair of liver during obstructive
cholestasis and aggravates the disease with early fatal consequences; these effects were strongly associated with oxidative stress.This work was supported by grants of the CONACYT 252942, 236558, and 166042, CONACYT Fronteras de la Ciencia 1320, Asociación Mexicana de Hepatología, and SEP-PRODEP-913026-1461211, Universidad Autónoma Metropolitana Iztapalapa, by grants SAF-2011-23031 and SAF-2012-34831 from Plan Nacional de I+D, Spain, Fundació la Marató de TV3, La Mutua Madrileña, PI11/0325 (META) Grant from the Instituto Salud Carlos III, by the support of CIBEREHD, and by the Center Grant P50-AA-11999 from Research Center for Liver and Pancreatic Diseases funded by NIAAA/NIH.Peer Reviewe
Northern Shrimp (Pandalus borealis, Krøyer) from Spanish Bottom Trawl Survey 2009 in NAFO Div. 3LNO
The Spanish Institute of Oceanography carried out in 2009 two bottom trawl surveys in the NAFO Regulatory Area in Division 3NO and 3L during the months of June, July and August respectively. The results on Northern shrimp (Pandalus borealis) are presented and compared with those from previous surveys from the same series. In 2009 the catch (33 kg.) and estimated biomass (139 t.) confirm the decrease of shrimp importance from 2004 in 3NO. In 2009 the biomass estimated of northern shrimp in 3L Division was 74091 t. showing a drastic decline (50% with respect to 2008) after the upward trend a long the whole period studied.
Catch results from the surveys and data analysis are discussed in this paper
Relación entre estrategias activas de afrontamiento, burnout y engagement en futuros educadores
El objetivo del presente estudio fue evaluar el valor predictivo de las estrategias activas de afrontamiento sobre las dimensiones del burnout y del engagement en una muestra de 775 estudiantes de diferentes grados de Ciencias de la Educación. Se emplearon las versiones españolas del Maslach Burnout Inventory-Student Survey (MBI-SS), Utrecht Work Engagement Student Scale (UWES-SS) y del Coping Strategies Inventory (CSI). Los resultados revelan que la mayoría de las estrategias de afrontamiento activas predicen significativa pero negativamente el burnout y positivamente el engagement. Los programas de intervención deben contemplar estas estrategias para prevenir el burnout e incrementar el engagement.The aim of the present study was to evaluate the predictive value of approach coping on academic burnout and engagement dimensions in a sample of 775 students among different university grades of Educational Sciences. Spanish versions of the Maslach Burnout Inventory-Student Survey (MBI-SS), Utrecht Work Engagement Student Scale (UWES-SS) and Coping Strategies Inventory (CSI) were employed. The results show that most of the approach coping significantly and negatively predicts burnout but significantly and positively predicted engagement. The intervention programs have to consider those strategies to prevent burnout and to increase engagement
Does Genital Self-image Correspond with Sexual Health before and after Vaginoplasty?
Patient-reported outcomes regarding sexual health are lacking or have not been validated for transgender patients following vaginoplasty. The aim of this study is to further characterize the difference in sexual health, genital self-image, and the relationship between them for patients who were pre- and postvaginoplasty.
METHODS: A community advisory board informed an anonymous online survey utilizing patient-reported outcomes. Pre- and postvaginoplasty respondents were recruited online. Survey measures included the Female Genital Self-Image Scale (FGSIS) and the Patient-Reported Outcomes Measurement Information System sexual health measures. Welch approximation t tests were performed for FGSIS and Patient-Reported Outcomes Measurement Information System questions, using Bonferroni correction.
RESULTS: A total of 690 respondents prevaginoplasty (n = 525; 76%) and postvaginoplasty (n = 165; 24%) participated. The postoperative cohort, compared with the preoperative cohort, reported higher scores for orgasm (P = 0.0003), satisfaction (P = 0.001), and pleasure (P = 0.002). FGSIS total score was higher among postoperative respondents (79.4% ± 17.1%) than preoperative respondents (50.6% ± 15.1%) (P \u3c 0.0001). Using Spearman rho, no significant correlation between FGSIS total score and any Patient-Reported Outcomes Measurement Information System subsectional measures was observed for the postoperative cohort, but a correlation (P \u3c0.001) was observed for the preoperative cohort.
CONCLUSIONS: Individuals who are contemplating vaginoplasty have worse sexual health and genital self-image than those who underwent vaginoplasty, yet genital self-image does not correlate directly with sexual health. Sexual health is multimodal for each person
INDICADORES DE SOSTENIBILIDAD: UN ANÁLISIS MULTIVARIANTE APLICANDO HJ-BIPLOT
Biplot methodology allows representing the information contained within a data matrix into a more reduced dimensional space with minimum information lost. To obtain a higher quality of representation of both axes of the data matrix, an extension of the Classical Biplot is used: HJ-Biplot. The Global Reporting Initiative (GRI) is an international organization whose purpose is to promote the development of sustainability reports by all kind of organizations for their economic, social and environmental performance as a commitment to their Corporate Social Responsibility. Brazil registers an increasing number of companies committed of publishing their progress in GRI’s social responsibility reports. The largest companies of this country are grouped in three well-defined clusters based on their level of response to these three groups of indicators. This article aims to highlight the relationship between sustainability performance indicators reported to the GRI during 2011 and 2012, and the possible grouping of Brazilian companies based on the type of indicator where they are more related.Los métodos Biplot permiten representar la información contenida en una matriz de datos en un espacio de menor dimensión con la menor pérdida de información, para obtener una máxima calidad de representación de ambos ejes de la matriz de datos se utiliza una extensión del Biplot clásico: HJ-Biplot. El Global Reporting Initiative (GRI) es una organización cuyo propósito es impulsar la elaboración de memorias de sostenibilidad por parte de todo tipo de organizaciones en sus ejercicios de actuación económica, social y ambiental como compromiso a la responsabilidad social de las empresas. Brasil registra un creciente número de empresas comprometidas en reportar sus avances en los informes del GRI. Las empresas grandes de este país se agrupan en tres clúster bien definido en base a su nivel de respuesta a estos indicadores. Este artículo pretende destacar la relación existente entre los indicadores de desempeño de sostenibilidad reportados por el GRI durante los años 2011 y 2012, y las posibles agrupaciones de las empresas según el tipo de indicador al que más se relacionan
