Measurement of single top-quark production in association with a W boson in the single-lepton channel at \sqrt{s} = 8\,\text {TeV} with the ATLAS detector

The production cross-section of a top quark in association with a W boson is measured using proton–proton collisions at \sqrt{s} = 8\,\text {TeV}. The dataset corresponds to an integrated luminosity of 20.2\,\text {fb}^{-1}, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. The analysis is performed in the single-lepton channel. Events are selected by requiring one isolated lepton (electron or muon) and at least three jets. A neural network is trained to separate the tW signal from the dominant t{\bar{t}} background. The cross-section is extracted from a binned profile maximum-likelihood fit to a two-dimensional discriminant built from the neural-network output and the invariant mass of the hadronically decaying W boson. The measured cross-section is \sigma _{tW} = 26 \pm 7\,\text {pb}, in good agreement with the Standard Model expectation

The construction process of pedagogical knowledge among nursing professors

Didactic knowledge about contents is constructed through an idiosyncratic synthesis between knowledge about the subject area, students' general pedagogical knowledge and the teacher's biography. This study aimed to understand the construction process and the sources of Pedagogical Content Knowledge, as well as to analyze its manifestations and variations in interactive teaching by teachers whom the students considered competent. Data collection involved teachers from an undergraduate nursing program in the South of Brazil, through non-participant observation and semistructured interviews. Data analysis was submitted to the constant comparison method. The results disclose the need for initial education to cover pedagogical aspects for nurses; to assume permanent education as fundamental in view of the complexity of contents and teaching; to use mentoring/monitoring and the value learning with experienced teachers with a view to the development of quality teaching

Nursing teachers in clinical training areas: a phenomenological focus El docente de enfermería en los campos de práctica clínica: un enfoque fenomenológico O docente de enfermagem nos campos de prática clínica: um enfoque fenomenológico

During theoretical and practical activities in clinical training areas, nursing teachers provide the bases needed for the development of future professionals. The goal is to understand the experience of nursing teachers with nursing students in clinical training areas. Therefore, a phenomenological qualitative method was chosen, and Martin Heidegger&#39;s philosophical framework was used to support data analysis. Five faculty from a Chilean university participated in the study. The analysis permitted discovering the following themes: being a faculty at the hospital, contact with nurse practitioners and being a faculty in care teaching. The study demonstrated that teaching/care integration is a constructive element that facilitates the teaching and learning process, aiming to prepare nursing professionals who incorporate the bases of authentic care into their activities.<br>El docente de enfermería en el desarrollo de las actividades teórico-prácticas en los campos de práctica clínica proporciona las bases necesarias para el desarrollo del futuro profesional. El objetivo propuesto es comprender la vivencia de los docentes de enfermería junto a los estudiantes de enfermería, en los campos de práctica clínica. Para ello se optó por una metodología cualitativa fenomenológica, y para fundamentar el análisis de los datos, se utilizó el marco filosófico de Martín Heidegger. Cinco docentes de una universidad de Chile participaron del estudio. El análisis posibilitó descubrir los siguientes temas: ser docente en el hospital, la convivencia con enfermeras clínicas y ser docente en la enseñanza del cuidado. El estudio demostró que la integración docente/asistencial es un elemento constructivo y facilitador del proceso de enseñanza y aprendizaje, que busca la formación de profesionales de enfermería que incorporen en su actuación las bases de un cuidado auténtico.<br>No desenvolvimento das atividades teórico-práticas nos campos de prática clínica, o docente de enfermagem proporciona as bases necessárias para o desenvolvimento do futuro profissional. O objetivo proposto foi compreender a vivência dos docentes de enfermagem, junto aos estudantes de enfermagem, nos campos de prática clínica. Para isso, optou-se por metodologia qualitativa fenomenológica e, para fundamentar a análise dos dados, foi adotado o referencial filosófico de Martin Heidegger. Cinco docentes de uma universidade do Chile participaram do estudo. A análise possibilitou descobrir os seguintes temas: ser docente no hospital, a convivência com enfermeiras clínicas e ser docente no ensino do cuidado. O estudo demonstrou que a integração docente/assistencial é elemento construtivo e facilitador do processo ensino/aprendizagem, buscando a formação de profissionais da enfermagem que incorporem, na sua atuação, as bases de cuidado autêntico
