Beliefs about Teaching styles of future coaches: a study in initial training in Physical Education

Os futuros treinadores trazem à formação inicial experiências pessoais capazes de desenvolver crenças e influenciar na aquisição de seus conhecimentos. Essas crenças sobre o ensino determinam as ações e procedimentos adotados nas aulas. Buscou-se identificar as crenças sobre os estilos de ensino dos futuros treinadores na formação inicial em Educação Física de uma instituição comunitária no estado de Santa Catarina. Esta pesquisa quantitativa, que contemplou uma amostra do tipo intencional e não-probabilística coletou dados a partir de uma versão traduzida e adaptada do Instrumento para coletar as crenças dos professores sobre seus estilos de ensino utilizados na educação física com 42 futuros treinadores. Os resultados revelaram que o estilo de ensino prático foi o mais utilizado entre todos os participantes. Ao considerar apenas aqueles futuros treinadores com experiência profissional em estágios obrigatórios e/ou não-obrigatório, o estilo de ensino com maior pontuação a produção divergente ao passo que entre os futuros treinadores com experiências enquanto atletas, o estilo mais pontuado foi o recíproco. Conclui-se que os futuros treinadores investigados apresentaram crenças mais voltadas aos estilos de reprodução.Los futuros coaches aportan a la formación inicial experiencias personales capaces de desarrollar creencias e influir en la adquisición de sus conocimientos. Estas creencias sobre la enseñanza determinan las acciones y procedimientos adoptados en las clases. Se buscó identificar las creencias sobre los estilos de enseñanza de los futuros entrenadores en la formación inicial en Educación Física en una institución comunitaria del estado de Santa Catarina. Esta investigación cuantitativa, que incluyó una muestra intencional y no probabilística, recopiló datos de una versión traducida y adaptada del Instrumento para recoger las creencias de los docentes sobre sus estilos de enseñanza utilizados en educación física con 42 futuros formadores. Los resultados revelaron que el estilo de enseñanza práctica fue el más utilizado entre todos los participantes. Al considerar solo a aquellos futuros entrenadores con experiencia profesional en pasantías obligatorias y / o no obligatorias, el estilo de enseñanza con mayor puntuación mostró producción divergente, mientras que entre los futuros entrenadores con experiencia como deportistas, el estilo más puntuado fue el recíproco. Se concluye que los futuros entrenadores investigados tenían creencias más centradas en los estilos de reproducción.Future coaches bring to initial training personal experiences capable of developing beliefs and influencing the acquisition of their knowledge. These beliefs about teaching determine the actions and procedures adopted in classes. We sought to identify the beliefs about the teaching styles of future coaches in initial training in Physical Education at a community institution in the state of Santa Catarina. This quantitative research, which included an intentional and non-probabilistic sample, collected data from translated and adapted version of an Instrument to collect teachers' beliefs about their teaching styles used in physical education with 42 future trainers. The results revealed that the practical teaching style was the most used among all participants. When considering only those future coaches with professional experience in mandatory and/or non-mandatory internships, the teaching style with the highest score showed divergent production, whereas among future coaches with experience as athletes, the most scored style was reciprocal. It is concluded that the future coaches investigated had beliefs more focused on reproduction styles.Facultad de Humanidades y Ciencias de la Educació

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt
