Development of Expertise in Spanish Elite Basketball Coaches.(El desarrollo de la pericia en los entrenadores españoles expertos en baloncesto.)

<b>Abstract</b><p align="justify">The present study was designed to address two issues: first, to identify the different development stages that eight expert Spanish basketball coaches go through; and second, to determine the possible factors that have contributed to the formative or training, process of the expert coach. Qualitative data were gathered in semi-structured interviews. The coaches worked with the men’s first Spanish Basketball League (“ACB” league) or the Spanish national selection. Our findings reveal four stages in the coach development process. These stages were the consequence mainly of a gradual progression in thinking and reflective practice that enabled the coach to optimize the necessary skills for high performance. In addition, all the coaches interviewed reflected an intense dedication and commitment over many years to their work, as well as an ongoing quest for improvement.</p><b>Resumen</b><p align="justify">El presente estudio fue diseñado para hacer frente a dos cuestiones: en primer lugar, identificar las diferentes etapas formativas de ocho entrenadores expertos en baloncesto, y en segundo lugar, determinar los posibles factores que han contribuido a la formación del entrenador experto.

The Role of S. cerevisiae Sub1/PC4 in Transcription Elongation Depends on the C-Terminal Region and Is Independent of the ssDNA Binding Domain

Saccharomyces cerevisiae Sub1 (ScSub1) has been defined as a transcriptional stimulatory protein due to its homology to the ssDNA binding domain (ssDBD) of human PC4 (hPC4). Recently, PC4/Sub1 orthologues have been elucidated in eukaryotes, prokaryotes, and bacteriophages with functions related to DNA metabolism. Additionally, ScSub1 contains a unique carboxyl–terminal region (CT) of unknown function up to date. Specifically, it has been shown that Sub1 is required for transcription activation, as well as other processes, throughout the transcription cycle. Despite the progress that has been made in understanding the mechanism underlying Sub1′s functions, some questions remain unanswered. As a case in point: whether Sub1’s roles in initiation and elongation are differentially predicated on distinct regions of the protein or how Sub1′s functions are regulated. Here, we uncover some residues that are key for DNA–ScSub1 interaction in vivo, localized in the ssDBD, and required for Sub1 recruitment to promoters. Furthermore, using an array of genetic and molecular techniques, we demonstrate that the CT region is required for transcription elongation by RNA polymerase II (RNAPII). Altogether, our data indicate that Sub1 plays a dual role during transcription—in initiation through the ssDBD and in elongation through the CT region.Fil: Collin, Alejandro Alberto.

Detection of Rabbit Hemorrhagic Disease Virus GI.2/RHDV2/b in the Mediterranean Pine Vole ( Microtus duodecimcostatus) and White-Toothed Shrew ( Crocidura russula)

The European wild rabbit ( Oryctolagus cuniculus) is a key prey species on the Iberian Peninsula, and several predator species that are at risk of extinction are dependent on them as prey. A new rabbit hemorrhagic disease (RHD) virus genotype (GI.2/RHDV2/b) emerged in 2010 and posed a threat to wild rabbit populations. During a survey aimed at investigating RHD epidemiology in wild rabbits, GI.2/RHDV2/b was detected by duplex real-time PCR in carcasses of one Mediterranean pine vole ( Microtus duodecimcostatus) and two white-toothed shrews ( Crocidura russula). Laboratory New Zealand white rabbits that were challenged with inocula obtained from the liver of the small mammals died showing RHD lesions, confirming the infectiousness of the isolates. Phylogenetic analysis of the VP60 gene nucleotide sequences showed complete homology between the isolates from the two small mammal species and a high degree of similarity, but not complete homology, to GI.2/RHDV2/b sequences from wild rabbits. The GI.2/RHDV2/b genotype has not been reported in species outside the order Lagomorpha

A Light Calibration System for the ProtoDUNE-DP Detector

A LED-based fiber calibration system for the ProtoDUNE-Dual Phase (DP) photon detection system (PDS) has been designed and validated. ProtoDUNE-DP is a 6x6x6 m3 liquid argon time-projection-chamber currently being installed at the Neutrino Platform at CERN. The PDS is based on 36 8-inch photomultiplier tubes (PMTs) and will allow triggering on cosmic rays. The system serves as prototype for the PDS of the final DUNE DP far detector in which the PDS also has the function to allow the 3D event reconstruction on non-beam physics. For this purpose an equalized PMT response is desirable to allow using the same threshold definition for all PMT groups, simplifying the determination of the trigger efficiency. The light calibration system described in this paper is developed to provide this and to monitor the PMT performance in-situ.Comment: 15 pages, 5 figure

El clima motivacional a les classes d’Educació Física: una aproximació pràctica des de la Teoria de Fites d’Assoliment

Al treball següent es fa una anàlisi dels processos motivacionals que es desenvolupen a les classes d’Educació Física. Prenent com a fonament la Teoria de les Fites d’Assoliment (Nicholls, 1989; Ames, 1992), s’expliquen cada un dels diferents constructes que formen la teoria esmentada (Orientacions, Climes i Implicacions Motivacionals) i la relació entre ells. També s’hi exposen diverses investigacions que han demostrat aquestes relacions, i de quina manera el desenvolupament d’un clima que implica vers la tasca pot millorar i fer més adaptatius els patrons conductuals dels alumnes. Finalment, es fa una proposta metodològica per desenvolupar un clima que impliqui vers la tasca per part del professorat d’Educació Física, amb els beneficis que això reporta

La implicación motivacional de jugadores jóvenes de fútbol y su relación con el estado de Flow y la satisfacción en competición

El propósito de este estudio ha sido intentar determinar las variables predictoras del estado de implicación motivacional de jóvenes jugadores de fútbol y la relación que el estado de implicación guarda con el Estado de Flow y la atisfacción con el rendimiento obtenido en competición. Para ello, 117 futbolistas rellenaron un conjunto de cuestionarios para determinar: a) La orientación motivacional de los jugadores, b) la percepción de los criterios de éxito en el utilizados por el entrenador en el deporte y en una competición, c) el estado de implicación motivacional obtenido por los jugadores en competición, d) el Estado Flow obtenido en la competición, y e) la satisfacción con el rendimiento durante lacompetición. Los resultados se obtuvieron a través del cálculo de Modelos de Ecuaciones Estructurales, mostrando que únicamente las variables situacionales (percepción de criterios de éxito implicantes al ego y a la tarea) predicen de formasignificativa los estados de implicación al ego y a la tarea en competición, respectivamente. El estado de Flow en competición fue predicho tanto por el estado de implicación al ego como por el estado de implicación a la tarea. Por ltimo, la satisfacción en competición es predicha positivamente por el Estado de Flow en competición y la implicación a la tarea y negativamente por la implicación al ego.This study attemptd to determine the predictive variables related to goal involvement in young soccer players and the relationship between goal involvement and flow state and competition satisfaction. 117 soccer players completed a set of questionnaires to determine: a) the athletes' goal orientation, b) perception of sport and competition coaches' criteria for success, c) the players' competition goal involvement, d) competition flow state and e) the players' competition satisfaction. Results were obtained via Structural Equation Modelling and showed that only situational variables (perception of ego and task involving coach competition success criteria) were predictors of competition ego and task involvement respectively. Competition flow state was positively predicted by task and ego competition goal involvement. Finally, the results show that satisfaction was positively predicted by competition flow state and task-involvement, and negatively predicted by ego-involvement

Small ponds support high terrestrial bird species richness in a Mediterranean semiarid region

To access the final edited and published work see https://doi.org/10.1007/s10750-021-04552-7Ponds are among the world’s most endan gered freshwater ecosystems. A comprehensive knowledge of pond biodiversity is urgently required to inform effective pond management and conserva tion actions. Most studies about pond biodiversity focus on aquatic taxa, while the terrestrial biodiver sity, especially of birds, has been little studied. Moreover, the few studies existing on pond biodiver sity do not account for different detection rates of species, thus yielding biased results. Here, we apply a hierarchical Bayesian modelling technique to data obtained from visual censuses to estimate bird species richness associated with small ponds in a semiarid region, considering the imperfect detection of species. The model incorporates specific responses to site characteristics (pond typology), landscape (environ mental heterogeneity) and at regional scale (mean annual precipitation). The studied ponds were used by two thirds of the terrestrial breeding bird community of the study region. Our modelling approach increased by an average of 7.5 species the observed site-specific richness. Drinking troughs supported a greater rich ness than other pond types. Environmental hetero geneity was positively related with species richness, whereas no clear relation was observed between richness and precipitation. In addition to ecosystem services provided by ponds to human welfare, our results suggest these small isolated habitats may act as key landscape elements for terrestrial birds in semiarid regions
