Teaching and learning in the clinical field: perspective of teachers, nurses and nursing students

This is a qualitative research, which used the social phenomenology of Alfred Schütz approach. Its purpose was meeting and discussing the expectations of teachers, nurses and students about teaching in the clinical field. Nine teachers, eleven nurses and eleven students of the Nursing Graduation grade from a public university of São Paulo were included in this study. Data were collected in 2012. As the results showed, there are expectations about the link between theory and practice that clinical teaching can offer and also the desire that such instruction enable the learners to develop a pro-active and participatory attitude. The reciprocity of perspectives was evident and should be considered when academic projects focused on nursing education are developed.Estudo qualitativo, com abordagem da fenomenologia social de Alfred Schütz, que teve como objetivo conhecer e discutir as expectativas dos docentes, enfermeiras e estudantes com relação ao ensino em campo clínico. Participaram do estudo nove docentes, 11 enfermeiras e 11 estudantes do Curso de Graduação em Enfermagem de uma universidade pública de São Paulo. A coleta dos dados foi realizada em 2012 e os resultados mostraram que os sujeitos esperam que o ensino clínico subsidie a articulação entre a teoria e a prática profissional; e almejam que tal ensino possibilite o desenvolvimento de uma postura próativa e participativa dos envolvidos na aprendizagem. A reciprocidade de perspectivas foi evidenciada, devendo ser considerada na elaboração de projetos pedagógicos voltados para a formação do enfermeiro

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
