Violencia de género en mujeres inmigrantes y españolas: magnitud, respuestas ante el problema y políticas existentes
2009
Objetivo: Comparar la prevalencia de la violencia de género entre mujeres inmigrantes y españolas. Describir sus respuestas ante esta situación y posibles diferencias entre ellas. Identificar intervenciones ya existentes en España sobre prevención y atención sociosanitaria de violencia de género dirigidas a inmigrantes. Métodos: Estudio transversal mediante encuesta autoadministrada en 10.202 mujeres que acudieron a centros de atención primaria en España (2006-2007). Análisis de contenido del informe de seguimiento de la ley 1/2004 de medidas de protección integral contra la violencia de género remitido por las comunidades autónomas (CC.AA.) (2005) y las leyes y planes autonómicos más recie…
Psychosocial safety climate: Conceptual distinctiveness and effect on job demands and worker psychological health
2012
Abstract Psychosocial safety climate is an emerging construct that refers to shared perceptions regarding policies, practices, and procedures for the protection of worker psychological health and safety. The purpose of the research was to: (1) demonstrate that psychosocial safety climate is a construct distinct from related climate measures (i.e., physical safety climate, team psychological safety, and perceived organizational support); and (2) test the proposition that organizational psychosocial safety climate determines work conditions (i.e., job demands) and subsequently worker psychological health. We used samples from two different cultures; an Australian sample (N = 126 workers in 16…
Vardarbības pieredzes un uztvertā sociālā atbalsta saistība ar pozitīvu un negatīvu simptomu izteiktību šizofrēnijas pacientu vidū
2019
Pētījuma mērķis bija noskaidrot saistības starp šizofrēnijas pozitīvajiem un negatīvajiem simptomiem, bērnībā piedzīvoto vardarbību un sociālo atbalstu, kā arī noteikt, cik lielā mērā vardarbība un sociālais atbalsts prognozē simptomu izteiktību. Izlasi veidoja 120 dalībnieki ar diagnozi šizofrēnija – 78 sievietes un 42 vīrieši vecumā no 21 līdz 79 gadiem (M=43,28; SD=12,93). Vardarbības pieredze tika mērīta ar Bērnības traumas aptauju (Bernstein et al., 1994), sociālais atbalsts ar Daudzdimensionālo uztvertā sociālā atbalsta skalu (Zimet et al., 1988), šizofrēnijas simptomu izteiktība ar Pozitīvo un Negatīvo simptomu aptauju (Iancu, 2005). Pētījuma rezultāti parāda, ka izteiktāka vardarbīb…
Carbons from second generation biomass as sustainable supports for catalytic systems
2018
Abstract In this study activated carbons were produced from the wood of three different wood species (pine, birch, spruce). The resulting activated carbons were characterized in bulk for ash content, carbon content (elemental analyses), specific surface area, and pore size distribution, and at the surface by measuring the autogenerated pH and studying their structure by XPS. All the samples presented high surface areas and appeared to be mesoporous materials (mesopores >80%). The carbons were then used as support for AuPt nanoparticles and tested in the liquid phase oxidation of glycerol (GLY) and in the hydrogenation of levulinic acid (LA), two important chemicals from cellulose-based biom…
Conversion of Xylose to Furfural over Lignin-Based Activated Carbon-Supported Iron Catalysts
2020
In this study, conversion of xylose to furfural was studied using lignin-based activated carbon-supported iron catalysts. First, three activated carbon supports were prepared from hydrolysis lignin with different activation methods. The supports were modified with different metal precursors and metal concentrations into five iron catalysts. The prepared catalysts were studied in furfural production from xylose using different reaction temperatures and times. The best results were achieved with a 4 wt% iron-containing catalyst, 5Fe-ACs, which produced a 57% furfural yield, 92% xylose conversion and 65% reaction selectivity at 170 °

Density Functional Theory Investigation on the Nucleation and Growth of Small Palladium Clusters on a Hyper-Cross-Linked Polystyrene Matrix
2014
Density functional theory calculations were employed to investigate the nucleation and growth of small palladium clusters, up to Pd9, into a microcavity of the porous hyper-cross-linked polystyrene (HPS). The geometries and the electronic structures of the palladium clusters inside the HPS cavity, following the one-by-one atom addition, are affected by a counterbalance between the Pd–phenyl (Pd−Φ) and Pd–Pd interactions. The analysis performed on energetics, cavity distortions, and cluster geometries indeed suggest that the cluster growth is dominated by the Pd−Φ interactions up to the formation of Pd4 aggregates, whereas the metal–metal interactions actually rule the growth of the larger c…
