La formación de la identidad de género una mirada desde la filosofía
Mayobre Rodríguez,Purificación;
Revista Venezolana de Estudios de la Mujer , 2007,
Abstract: the reflection is focused on the determination of gender as a key to build the subjectivity. the hierarchy or asymmetry depicted by genders is an expression of a bipolarity inherent to the logical structure of western thinking, grounded on the ontological dualism of plato. femineity rises as a normative form of gender for all women. in this paper the philosophical roots of gender system are presented, as well as the wide and intense current discussion about what is and ought to be the meaning of being a woman or the femineity
Impact of orocecal transit time on patient's perception of lactose intolerance Influencia del tiempo de tránsito orocecal en la percepción de los síntomas de intolerancia a la lactosa

Revista Espa?ola de Enfermedades Digestivas , 2013,
Abstract: Background: symptoms attributed to the lactose intolerance are an important public health issue because of their prevalence and social relevance. Also because they may cause undue rejection of dairy products consume with potential health consequences. Transit time is a putative factor implied in the severity of symptoms associated with lactose. Objectives: to elucidate the relation between orocecal transit time (OCTT) and lactose intolerance symptoms. Methods: observational study in patients referred to a lactose hydrogen breath test who showed an increase in breath H2 excretion higher than 25 ppm. OCTT was measured with the breath test and symptoms of lactose tolerance with a validated scale. Symptoms were measured twice: before receiving the lactose, inquiring about self perceived symptoms when patients consumed dairy products at home ("home symptoms"), and again after completing the lactose breath test ("test symptoms"). Results: 161 patients were included. There was no correlation between OCTT and home symptoms (r = -0.1). When OCTT was faster than 60 minutes, intensity of "test symptoms" was similar to "home symptoms". However, in patients with normal or slow OCTT, the "home symptoms" were more intense than the "test symptoms" (p < 0.05). At home, symptoms were independent of OCTT but with the lactose test load the symptoms were proportionately more intense with faster OCTT. Conclusions: in lactose maldigesters, selfreported symptoms of lactose intolerance are more pronounced at home than after a high lactose challenge. Intolerance symptoms that patients attributed to lactose consume at home are due to factors other than fast OCTT. Antecedentes: los síntomas atribuidos a la intolerancia a la lactosa son un importante problema de salud pública. El tiempo de tránsito es un factor implicado en la severidad de los síntomas asociados al consumo de lactosa. Objetivos: elucidar la relación entre el tiempo de tránsito orocecal (TTOC) y los síntomas de intolerancia a la lactosa. Métodos: estudio observacional en pacientes con un test del aliento de hidrógeno con lactosa patológico (excreción de hidrógeno superior a 25 ppm). El TTOC se midió mediante el test del aliento y los síntomas mediante una escala previamente validada. Los síntomas se determinaron dos veces: antes de recibir la lactosa, preguntando acerca de los síntomas en casa cuando se consumen lácteos ("síntomas en casa"), y de nuevo después de completar el test del aliento con lactosa ("síntomas test"). Resultados: se han incluido 161 pacientes. No se observa correlación entre el TTOC y los sínto

Abstract: En este artículo se revisan distintos aspectos relacionados con las competencias numéricas tempranas. En primer lugar, se aborda en profundidad la polémica entre los defensores y detractores de las habilidades numéricas de los bebés, prestando especial atención a los estudios sobre la discriminación de las cantidades y las habilidades aritméticas no simbólicas. En segundo lugar, se ocupa del subitizing centrándose en el cambio que se produce de los patrones perceptivos a los conceptuales. Finalmente, en tercer lugar, se recogen los estudios sobre la habilidad de contar, haciendo hincapié en una línea de investigación especialmente prometedora relacionada con la diferenciación entre los aspectos esenciales (reglas lógicas) y no esenciales (reglas convencionales) del conteo.Is there anything more to count about numeracy skills of babies and toddlers?ABSTRACTThis paper reviews the research conducted on early numerical competencies. First, the debate between defenders and detractors of babies numerical competences is presented, taking especially into account research on quantity discrimination and non-symbolic arithmetical skills. Second, we make a short review of subitizing skills, stressing the change from perceptual to conceptual patterns. And third, we focus on counting, emphasizing recent and outstanding research on children′s capacity to distinguish essential counting aspects (logical rules) from nonessential ones (conventional rules).

Abstract: Este trabajo parte de una revisión general de la iniciativa empresarial de los jóvenes espa oles para proponer un modelo sociocognitivo del comportamiento emprendedor y sus desencadenantes durante la etapa universitaria. En la validación de dicho modelo, se describen los resultados de un estudio de autoinforme llevado a cabo con una muestra representativa de 400 estudiantes de la Universidad de León. Los datos recabados fueron tratados estadísticamente a través de análisis factorial exploratorio y análisis multivariado de la varianza (MANOVA). Los resultados obtenidos permitieron identificar cinco componentes en el estudio de la conducta emprendedora de los encuestados, en términos de autoeficacia emprendedora, expectativas de resultados extrínsecos e intrínsecos, intereses emprende-dores y elección de carrera emprendedora. En general, los estudiantes de titulaciones Socio-Jurídicas y Técnicas tuvieron puntuaciones medias más altas en dichas dimensiones que sus iguales de otras ramas académicas. Las implicaciones de tales resultados para el dise o de programas académicos adaptados al EEES son discutidas.This paper presents a general review of entrepreneurship in Spanish young people to propose a social cognitive model of entrepreneurial behaviour and its triggers in university contexts. To validate the model, we describe the results from a study carried out with a sample of 400 undergraduates at the University of León, in Spain. Data was analyzed by exploratory factor analysis and multivariate analysis of variance (MANOVA). Findings identified five components in the study of participants’ entrepreneurial behaviour, particularly, self-efficacy, extrinsic and intrinsic outcome expectations, entrepreneurial interests and career choice. In general, students within Social and Technical degrees displayed higher mean scores in those variables than undergraduates in other academic areas. Implications of these results for the design of academic programmes adapted to the EHEA are discussed.
Metagenomics of the Deep Mediterranean, a Warm Bathypelagic Habitat

PLOS ONE , 2007, DOI: 10.1371/journal.pone.0000914
Abstract: Background Metagenomics is emerging as a powerful method to study the function and physiology of the unexplored microbial biosphere, and is causing us to re-evaluate basic precepts of microbial ecology and evolution. Most marine metagenomic analyses have been nearly exclusively devoted to photic waters. Methodology/Principal Findings We constructed a metagenomic fosmid library from 3,000 m-deep Mediterranean plankton, which is much warmer (~14°C) than waters of similar depth in open oceans (~2°C). We analyzed the library both by phylogenetic screening based on 16S rRNA gene amplification from clone pools and by sequencing both insert extremities of ca. 5,000 fosmids. Genome recruitment strategies showed that the majority of high scoring pairs corresponded to genomes from Rhizobiales within the Alphaproteobacteria, Cenarchaeum symbiosum, Planctomycetes, Acidobacteria, Chloroflexi and Gammaproteobacteria. We have found a community structure similar to that found in the aphotic zone of the Pacific. However, the similarities were significantly higher to the mesopelagic (500–700 m deep) in the Pacific than to the single 4000 m deep sample studied at this location. Metabolic genes were mostly related to catabolism, transport and degradation of complex organic molecules, in agreement with a prevalent heterotrophic lifestyle for deep-sea microbes. However, we observed a high percentage of genes encoding dehydrogenases and, among them, cox genes, suggesting that aerobic carbon monoxide oxidation may be important in the deep ocean as an additional energy source. Conclusions/Significance The comparison of metagenomic libraries from the deep Mediterranean and the Pacific ALOHA water column showed that bathypelagic Mediterranean communities resemble more mesopelagic communities in the Pacific, and suggests that, in the absence of light, temperature is a major stratifying factor in the oceanic water column, overriding pressure at least over 4000 m deep. Several chemolithotrophic metabolic pathways could supplement organic matter degradation in this most depleted habitat.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0047200
Abstract: Background Only multifaceted hospital wide interventions have been successful in achieving sustained improvements in hand hygiene (HH) compliance. Methodology/Principal Findings Pre-post intervention study of HH performance at baseline (October 2007– December 2009) and during intervention, which included two phases. Phase 1 (2010) included multimodal WHO approach. Phase 2 (2011) added Continuous Quality Improvement (CQI) tools and was based on: a) Increase of alcohol hand rub (AHR) solution placement (from 0.57 dispensers/bed to 1.56); b) Increase in frequency of audits (three days every three weeks: “3/3 strategy”); c) Implementation of a standardized register form of HH corrective actions; d) Statistical Process Control (SPC) as time series analysis methodology through appropriate control charts. During the intervention period we performed 819 scheduled direct observation audits which provided data from 11,714 HH opportunities. The most remarkable findings were: a) significant improvements in HH compliance with respect to baseline (25% mean increase); b) sustained high level (82%) of HH compliance during intervention; c) significant increase in AHRs consumption over time; c) significant decrease in the rate of healthcare-acquired MRSA; d) small but significant improvements in HH compliance when comparing phase 2 to phase 1 [79.5% (95% CI: 78.2–80.7) vs 84.6% (95% CI:83.8–85.4), p<0.05]; e) successful use of control charts to identify significant negative and positive deviations (special causes) related to the HH compliance process over time (“positive”: 90.1% as highest HH compliance coinciding with the “World hygiene day”; and “negative”:73.7% as lowest HH compliance coinciding with a statutory lay-off proceeding). Conclusions/Significance CQI tools may be a key addition to WHO strategy to maintain a good HH performance over time. In addition, SPC has shown to be a powerful methodology to detect special causes in HH performance (positive and negative) and to help establishing adequate feedback to healthcare workers.

Archivos Espa?oles de Urología (Ed. impresa) , 2010, DOI: 10.4321/S0004-06142010000700013
Abstract: objective: to report a new case of bladder schistosomiasis. methods: a 21-year-old patient came to our consultation with gross hematuria several weeks before, existing reddish lesions in the cystoscopy that suggested the existence of an atypical bladder tumor. results: after intense blood and urine test, ultrasonography and intravenous urography, transurethral resection of bladder was performed and the diagnosis on histological examination was bladder schistosomiasis. conclusions: given the high prevalence of schistosomiasis in the sub-saharan countries and later clinical epidemiologic implications, the appearance of macro or microscopic hematuria in black race immigrants, or even any urinary symptoms, it is necessary a complete evaluation, at least with a parasitological analysis (being the bilharziasis the most probably reason). the patients who have suffered severe urinary schistosomiasis must complete long-term follow-up to prevent bladder carcinoma.

Abstract: background: beta hemolytic group a streptococcus only exceptionally produces aggressive disease with high lethality. even more uncommon is the occurrence of an outbreak. in spain, no outbreak in child care center has been previously described. methods: descriptive study of an outbreak of streptococcal toxic shock syndrome (3 cases, one lethal) in a child care center, which motivated the health care intervention with chemoprophylaxis, the closure of the child care center and the study of contacts. we analyzed the determinants of infection in the invasive and non-invasive cases, and the results of the pharyngeal culture of contacts. results: we identified 3 invasive and 14 non-invasive cases between 40 children attending the child care center (attack rate 42.5%). we studied 19 possible determinants of the infection, finding only an association with being over the age of 24 months and the assistance to the handouts classroom (that of the oldest children). it was not associated with chickenpox. all children attending the child care center, its staff (4 women) and 258 contacts were microbiologically investigated. in 12 children the emm 4 strain was isolated, including 2 of 3 cases with invasive disease. in 13 of 258 contacts other strains of beta hemolytic group a streptococcus were isolated, but in none of them the strain responsible of the outbreak was found. azytromicin chemoprophylaxis was implemented for all children and contacts, and in those with a positive isolation, the culture was repeated until negative. conclusions: the invasive strain circulated only in the child care center. azytromicin chemoprophylaxis eradicated effectively the infection.
Transnationalism between Galicia and Northern Portugal: An Emerging Cosmopolitism  [PDF]
Xaquín S. Rodríguez Campos
Sociology Mind (SM) , 2017, DOI: 10.4236/sm.2017.74010
Abstract: This paper deals with the formation of a transnational society between Galicia and the Northern part of Portugal, analysed from an anthropological point of view. Concepts like cosmopolitism, ethnicity, liminality, and memory are central in the theoretical discussion for interpreting the processes of transnationalism. The suppression of the borders in the post-national European Union made the creation of transnational communities near the states’ borders possible. This process, in the case of the Galician-Portuguese borders, has developed depending on the ethnic processes, once the Spanish and Portuguese states attained democracies. The concept of a cosmopolitan nation has also been central in the discussion of how ethnicity and nationalism intervene in the process of transnationalism.
