(Re)Construction of gendered identities in educational and social spaces. Pedagogical and psychological contributions.

In this paper we analyze the role of education in the configuration of gendered models of space, both at home and in the city, and we also consider the uneven distribution of power through educational contexts in terms of visibility, prominence and occupation of territory. Considering critically the regulatory nature that applies in these settings we intend to generate potential transformations of the persistent models of spatial segregation and stereotyped behaviours . Likewise, we propose to try out the environmental autobiography -in the education of future professionals -as a suitable didactic resource aimed at reconstructing the subjective experi ence of sexual differentiation of space and also to encourage questioning on our own sexism. We conclude demanding, in addition, the consideration of the possibilities of the biophilic design in order to promote childhood health through projects that arti culate gender and environment, equality and sustainability

Optical, vibrational, thermal, electrical, damage and phase-matching properties of lithium thioindate

Lithium thioindate (LiInS$_{2}$) is a new nonlinear chalcogenide biaxial material transparent from 0.4 to 12 $\mu$m, that has been successfully grown in large sizes and good optical quality. We report on new physical properties that are relevant for laser and nonlinear optics applications. With respect to AgGaS(e)$_2$ ternary chalcopyrite materials, LiInS$_{2}$ displays a nearly-isotropic thermal expansion behavior, a 5-times larger thermal conductivity associated with high optical damage thresholds, and an extremely low intensity-dependent absorption allowing direct high-power downconversion from the near-IR to the deep mid-IR. Continuous-wave difference-frequency generation (5-11$\mu$m) of Ti:sapphire laser sources is reported for the first time.Comment: 27 pages, 21 figures.

Desastres y procesos psicosociales : desde la crisis en la gestión hacia la gestión de las crisis

Tesis de la Universidad Complutense de Madrid, Facultad de Psicología, Departamento de Psicología Social, leída el 20-12-1999El análisis de emergencias y desastres constituye un ámbito de investigación no sólo novedoso sino también privilegiado para las ciencias sociales en general, y para la psicología social en particular. La presente tesis organiza, en primer lugar, una lectura histórica de las aportaciones sociológicas y psicológicas al estudio de estos temas, contextualizando los cambios en las orientaciones teóricas y explicitando los principales interrogantes científicos de cada uno de los períodos identificados. Tal historia científico-social permite vislumbrar un novedoso campo: el de la gestión de crisis, que aspira a desterrar las connotaciones de mala suerte y fatalidad imbricadas etimológicamente a la palabra desastre. El concepto de crisis se convierte así en el hilo conductor de la investigación empírica que se presenta en segundo término. Proyectando la investigación de crisis industriales a ambientes urbanos vulnerables, y se desarrolla una propuesta metodológica para la reconstrucción y diagnóstico de dos casos de grandes incendios en la ciudad de Madrid. El análisis comparativo de éstos es el recurso escogido para hacer inferencias acerca de los procesos piscosociales en ellos implicados. Si la expresión Crisis en la Gestión supone recalcar los aspectos de incertidubmre, desorganización, estrés y perturbación en situaciones que exigen tomar decisiones y actuar contra reloj, serán los postulados de la Gestión de Crisis los que permitan captar los procesos organizacionales subyacentes de las mismas y los que se movilizan al afrontarlas. Es decir, trascendiendo los factores que operan como meros desencadenantes se resitúan aquellos que pueden contribuir entareas de prevención. Por ello se concluye con un esbozo de modelo integrador de compos de investigación de riesgos, crisis y desastres que articula conceptualmente diversas áreas de especialización; las mismas han alcanzado distintos grados de madurez en las últimas décadas pero se han desarrollado con virtual autonomía.Depto. de Psicología Social, del Trabajo y DiferencialFac. de PsicologíaTRUEpu

Plasma monomeric ApoA1 and high-density lipoprotein bound ApoA1 are markedly decreased and associated with low levels of lipophilic antioxidants in sickle cell disease: A potential new pathway for therapy.

Patients with sickle cell disease (SCD) exhibit high levels of reactive oxygen species and low plasma levels of lipophilic antioxidants, which may contribute to end-organ damage and disease sequelae. Apolipoprotein A1, the major apolipoprotein of high-density lipoprotein (HDL), is mainly secreted by the intestine and liver in the form of monomeric ApoA1 (mApoA1) present in plasma. Cholesterol and α-tocopherol are delivered to ApoA1 via the ATP-binding cassette transporter, subfamily A, member 1 (ABCA1). We measured cholesterol, mApoA1, ApoA1, and lipophilic antioxidants in the plasma of 17 patients with SCD and 40 healthy volunteers. Mean HDL cholesterol (-C) levels in SCD patients and healthy subjects were 59.3 and 48.1 mg/dL, respectively, and plasma lutein, zeaxanthin, and α-tocopherol were 64.0%, 68.7%, and 9.1% lower, respectively. To compare SCD to healthy subjects with similar HDL-C, we also performed subgroup analyses of healthy subjects with HDL-C above or below the mean. In SCD, the mApoA1 level was 30.4 μg/mL; 80% lower than 141 μg/mL measured in healthy volunteers with similar HDL-C (56.7 mg/dL). The mApoA1 level was also 38.4% greater in the higher versus lower HDL-C subgroups (p = .002). In the higher HDL-C subgroup, lutein and zeaxanthin transported by HDL were 48.9% (p = .01) and 41.9% (p = .02) higher, respectively, whereas α-tocopherol was 31.7% higher (p = .003), compared to the lower HDL-C subgroup. Plasma mApoA1 may be a marker of the capacity of HDL to capture and deliver liposoluble antioxidants, and treatments which raise HDL may benefit patients with high oxidative stress as exemplified by SCD

Seroprevalence of anti-HEV IgG in children: very early exposure in young children in a hyperendemic region

Background and objectivesHepatitis E virus (HEV) can be considered an emerging zoonotic pathogen and is an important cause of acute viral hepatitis in high-income countries. Corsica has been identified as a hyperendemic region for HEV. We aimed to characterize the prevalence of IgG among children and estimate the annual force of infection of HEV.MethodsFrom April 2020 to June 2021, we collected 856 “residual sera” in 13 medical biology laboratories. Sera were tested using the Wantaï HEV IgG assay. Data were weighted according to the distribution by sex and age of the real Corsican population. Serocatalytic models were applied to assess the annual force of infection of HEV.ResultsThe weighted seroprevalence was 30.33% [27.15–34.0]. The seroprevalence was only associated with increasing age (7.25–40.52%; p < 0.001). The annual probability of infection was 5.4% for adults and children above 10-year-old and 2.2% for children under 10 yo.ConclusionOur study demonstrates that in the hyperendemic island of Corsica, (i) exposure of the population to HEV is homogeneous at the spatial level with no difference between genders; (ii) HEV exposure occurs from birth, resulting in 7.4% seropositivity at the age of 4 years; and (iii) super exposure is observed after the age of 9 years. Accordingly, specific studies should be conducted to determine the breadth of the situation identified in our study. The role of the environment and its contamination by domestic or wild swine excreta should be investigated using a One Health approach

Standardization of in vitro digestibility and DIAAS method based on the static INFOGEST protocol

Background: The FAO recommends the digestible indispensable amino acid score (DIAAS) as the measure for protein quality, for which the true ileal digestibility needs to be assessed in humans or pigs. However, due to high costs and ethical concerns, the FAO strongly encourages as well the development of validated in vitro methods, which complement the in vivo experiments. Method: Recently, an in vitro workflow, based on the validated static INFOGEST protocol, was developed and compared towards in vivo data. In parallel to the validation with in vivo data, the repeatability and reproducibility of the in vitro protocol were tested in an international ring trial (RT) with the aim to establish an international ISO standard method within the International Dairy Federation (IDF). Five different dairy products (skim milk powder, whole milk powder, whey protein isolate, yoghurt, and cheese) were analyzed in 32 different laboratories from 18 different countries, across 4 continents. Results: in vitro protein digestibilities based on Nitrogen, free R-NH2, and total amino acids as well as DIAAS values were calculated and compared to in vivo data, where available. Conclusion: The in vitro method is suited for quantification of digestibility and will be further implemented to other food matricesinfo:eu-repo/semantics/publishedVersio
