Conocimiento metacognitivo de las estrategias y habilidades mentales utilizadas para resolver problemas: un estudio con profesores de ciencias en formación

El presente estudio pretende aproximarse al conocimiento metacognitivo sobre las estrategias y destrezas mentales en la resolución de problemas de diferente naturaleza que tiene el profesorado de secundaria de ciencias. Participaron 46 profesores en formación, 28 de la especialidad de Física y Química y 18 de la especialidad de Biología y Geología. Se obtuvo información mediante un cuestionario sobre frecuencia, eficacia y facilidad del uso de cinco estrategias de resolución de problemas en tres tipos de problemas: interpersonales, prácticos y académicos. A los participantes también se les pidió identificar las destrezas mentales implicadas en cada estrategia. Los resultados obtenidos son coherentes con dos investigaciones anteriore

Influence of the ovine genital tract microbiota on the species artificial insemination outcome. A pilot study in commercial sheep farms

To date, there is a lack of research into the vaginal and sperm microbiome and its bearing on artificial insemination (AI) success in the ovine species. Using hypervariable regions V3–V4 of the 16S rRNA, we describe, for the first time, the combined effect of the ovine microbiome of both females (50 ewes belonging to five herds) and males (five AI rams from an AI center) on AI outcome. Differences in microbiota abundance between pregnant and non-pregnant ewes and between ewes carrying progesterone-releasing intravaginal devices (PRID) with or without antibiotic were tested at different taxonomic levels. The antibiotic treatment applied with the PRID only altered Streptobacillus genus abundance, which was significantly lower in ewes carrying PRID with antibiotic. Mageebacillus, Histophilus, Actinobacilllus and Sneathia genera were significantly less abundant in pregnant ewes. In addition, these genera were more abundant in two farms with higher AI failure. Species of these genera such as Actinobacillus seminis and Histophilus somni have been associated with reproductive disorders in the ovine species. These genera were not present in the sperm samples of AI rams, but were found in the foreskin samples of rams belonging to herd 2 (with high AI failure rate) indicating that their presence in ewes’ vagina could be due to prior transmission by natural mating with rams reared in the herd

Asistencia a las urgencias psiquiátricas en Albacete.

Se han examinado las características de los pacientes atendidos en la Unidad de Urgencias Psiquiátricas de Albacete durante el año 1990. De los datos obtenidos destacan: 1) Los trastornos por alcohol y opiáceos fueron el grupo más numeroso, con casi un tercio de las urgencias. 2) Casi los dos tercios de las urgencias estuvieron entre las edades de 15 a 40 años. 3) Casi la cuarta parte de las mismas se quedaron ingresadas en la Unidad de Hospitalización Psiquiátrica. Y 4) La escasa incidencia de las urgencias enviadas por el juez

Prototyping of petalets for the Phase-II Upgrade of the silicon strip tracking detector of the ATLAS Experiment

In the high luminosity era of the Large Hadron Collider, the HL-LHC, the instantaneous luminosity is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing. To cope with the resultant increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The ITk consists of a silicon pixel and a strip detector and exploits the concept of modularity. Prototyping and testing of various strip detector components has been carried out. This paper presents the developments and results obtained with reduced-size structures equivalent to those foreseen to be used in the forward region of the silicon strip detector. Referred to as petalets, these structures are built around a composite sandwich with embedded cooling pipes and electrical tapes for routing the signals and power. Detector modules built using electronic flex boards and silicon strip sensors are glued on both the front and back side surfaces of the carbon structure. Details are given on the assembly, testing and evaluation of several petalets. Measurement results of both mechanical and electrical quantities are shown. Moreover, an outlook is given for improved prototyping plans for large structures.Comment: 22 pages for submission for Journal of Instrumentatio

Practicing what you preach: How cosmopolitanism promotes willingness to redistribute across the European Union

The political fault lines surrounding the European sovereign debt crisis have underlined the political relevance and the fragile foundation of public support for international redistribution in the European Union. Against the backdrop of an emerging political integration-demarcation divide, this article examines how cosmopolitanism structures people’s willingness to redistribute internationally within the European Union. To this aim, we conducted laboratory experiments on redistributive behaviour towards other European citizens in the United Kingdom and Germany and analysed cross-national survey data on support for international redistribution covering the EU-28. Our findings suggest that cosmopolitanism increases generosity towards other Europeans and support for international redistribution even when controlling for self-interest, support for national redistribution, concern for others, and political ideology

Lafora disease E3-ubiquitin ligase malin is related to TRIM32 at both the phylogenetic and functional level

<p>Abstract</p> <p>Background</p> <p>Malin is an E3-ubiquitin ligase that is mutated in Lafora disease, a fatal form of progressive myoclonus epilepsy. In order to perform its function, malin forms a functional complex with laforin, a glucan phosphatase that facilitates targeting of malin to its corresponding substrates. While laforin phylogeny has been studied, there are no data on the evolutionary lineage of malin.</p> <p>Results</p> <p>After an extensive search for malin orthologs, we found that malin is present in all vertebrate species and a cephalochordate, in contrast with the broader species distribution previously reported for laforin. These data suggest that in addition to forming a functional complex, laforin and perhaps malin may also have independent functions. In addition, we found that malin shares significant identity with the E3-ubiquitin ligase TRIM32, which belongs to the tripartite-motif containing family of proteins. We present experimental evidence that both malin and TRIM32 share some substrates for ubiquitination, although they produce ubiquitin chains with different topologies. However, TRIM32-specific substrates were not reciprocally ubiquitinated by the laforin-malin complex.</p> <p>Conclusions</p> <p>We found that malin and laforin are not conserved in the same genomes. In addition, we found that malin shares significant identity with the E3-ubiquitin ligase TRIM32. The latter result suggests a common origin for malin and TRIM32 and provides insights into possible functional relationships between both proteins.</p
