An integrated perspective of the most important factors driving the abundance of ammonia-oxidizing bacteria (AOB) and archaea (AOA) in natural ecosystems is lacking, especially in drylands. We evaluated how different climatic, abiotic, and nutrient-related factors determine AOA and AOB abundance in bare and vegetated microsites from grasslands throughout the Mediterranean Basin. We found a strong negative relationship between the abundance of AOA genes and soil fertility (availability of C, N, and P). Aridity and other abiotic factors (pH, sand content, and electrical conductivity) were more important than soil fertility in modulating the AOA/AOB ratio. AOB were more abundant under vegetated microsites, while AOA, highly resistant to stressful conditions, were more abundant in bare ground areas. These results suggest that AOA may carry out nitrification in less fertile microsites, while AOB predominate under more fertile conditions. Our results indicate that the influence of aridity and pH on the relative dominance of AOA and AOB genes is ultimately determined by local-scale environmental changes promoted by perennial vegetation. Thus, in spatially heterogeneous ecosystems such as drylands, there is a mutual exclusion and niche division between these microorganisms, suggesting that they may be functionally complementary. Abundance of amoA and amoB genes in soils from Stipa tenacissima grasslands along an aridity gradient in the Mediterranean Data on the abundance of amoA and amoB genes in soils from Stipa tenacissima grasslands along a Mediterranean aridity gradient (from Spain to Tunisia). The database also includes information about different soil variables and the abiotic characteristics of the sites surveyed. All the units and information about the variables are included in the "Metadata" spreadsheet. FEMS_dryad.xls

Purpose – The aim of this study was to analyse the link between the values that govern the functioning of cooperatives and their sustainability. Furthermore, the authors propose that this relationship is mediated by AMO(ability, motivation and opportunity) practices, which generate different behaviours and attitudes in their employees, thus strengthening the message of sustainable management that the directors of this kind of companies aim to transmit. Design/methodology/approach – This article presents a theoretical and empirical research model about the relationship between organisational values, AMO practices and sustainability in social economy firms. The proposed model was tested using the multivariate method of partial least squares structural equation modelling (PLS-SEM) with a sample of 124 cooperative companies. The information was gathered through a questionnaire with questions composed of measurement scales that had been previously validated by the reference literature. Findings – This work empirically demonstrates that the perceived support, respect and responsibility values are strongly related to sustainability, and that ability and opportunity-enhancing practices mediate the association of perceived support and responsibility with the sustainability of cooperatives. Originality/value – This work contributes to covering the lack of studies about which values support and impact the sustainability of organisations, and it provides information about the mediating role of certainAMO practices in the search for a more sustainable organisation, demonstrating that some practices are more relevant than others.

Este documento, es una herramienta de recogida de datos o cuestionarios, aplicados en el foco endémicos de Valverde del Camino (España) y en el foco endémicos de Oporto (Portugal) donde se convice con una enfermedad rara (ER) llamada Enfermedad de Andrade o AhTTR. Con estos cuestionarios se ha intentando estudiar desde las ciencias sociales, las as necesiades sociales de este colectivo afectado por esta ER. Son 4 modelos, cada uno de ellos destinados a un grupo de personas afectadas todas de una u otra forma por la Enfermedad de Andrade o AhTTR, como son: CuestionarioN1E_personas enfermas de AHTTR; CuestionarioN1F._Familiares de las personas enfermas de AhTTR y portadores asintomáticos; CuestionarioN2._Personal sanitario y CuestionarioN3_Poblacion en general. Dependerá en qué grupo o grupos se centre el estudio, el utilizar uno u otro modelo. Puede utilizarse de manera conjunta o por separado. Pueden ser extrapolables para estudiar /investigar otros focos endémicos de la enfermedad de Andrade o incluso profundizar desde las ciencias sociales en el estudio de las necesidades sociales de otras Enfermedades Raras, haciendo los cambios específicos de esas otras ER.

Contiene 3 ficheros correspondientes a la investigación realizada para el artículo "Memoria de trabajo o hábitos de sueño, ¿qué influye más en las habilidades de programación?" presentado para las XXVIII Jornadas sobre la Enseñanza Universitaria de la Informática (JENUI 2022), en el que se realizó una investigación donde cuarenta y cinco estudiantes de 4to curso del Grado en Ingeniería Multimedia realizaron, por un lado, dos cuestionarios con preguntas relativas a los lenguajes de programación Ensamblador y C++, junto con cuatro preguntas sobre hábitos de sueño, y por otro, una sesión donde cada estudiante realizó varias partidas al ejercicio Dual N-Back.

El fichero incluye los datos obtenidos del trabajo experimental que ha dado lugar a la publicación. El resumen del contenido de la misma es: TiO2-Cu photocatalysts (1 wt% Cu) containing different copper species have been prepared and used for the generation of hydrogen by photoreforming of cellulose (the major component of biomass) in water at room temperature using UV light. A positive effect of copper has been clearly observed, and the analysis of the role of the Cu species present shows that a mixture of Cu(I) and Cu(II) favors the process. Among the TiO2-Cu photocatalysts, the one prepared by a simple impregnation method and not heat-treated, which shows small and well dispersed copper species particles, gives the highest hydrogen production.
