Mindfulness, Compassion, and Self-Compassion as Moderator of Environmental Support on Competency in Mental Health Nursing

Abstract: This research explored the established relationship between environmental support and competency for Mental Health Nurses, intending to investigate whether the tendency to display higher levels of mindfulness, compassion, and self-compassion might buffer the effect of a poor environment on competency. One questionnaire was comprised of five pre-developed questionnaires, which included all items examining environmental support, competency, mindfulness, compassion, and self-compassion. Mental Health Nurses (n = 103) were recruited from online forums and social media group pages in the UK. The result showed environmental support related positively to competency. Furthermore, the positive relationship of competency with environmental support was moderated when controlling for compassion but did not with mindfulness and self-compassion, although subscales showed some further interactions. When poor environmental support influences the competency of mental health professionals, compassion and mindfulness-based interactions may have the potential to uphold competency

A surface science study of model catalysts. 2. Metal-support interactions in Cu/SiO2 model catalysts

The thermal stability of wet-chemically prepared Cu/SiO2 model catalysts containing nanometer-sized Cu particles on silica model supports was studied upon heating in hydrogen and ultrahigh vacuum. The surface and interface phenomena that occur are determined by the metal-support interactions. Heating in hydrogen results in a reduction of the metal-support interaction and sintering occurs via Cu particle migration at 350 °C. Annealing in ultrahigh vacuum up to 620 °C does not result in sintering of the Cu particles. When a 5 nm thin SiO2 layer on top of a Si(100) substrate is used as SiO2 model support, interdiffusion of Cu into the Si substrate takes place. For a 400-500 nm thick SiO2 layer, Cu suicide islands are formed by reaction between Cu and SiO2, which can be regenerated by exposure to air at room temperature for several hours. The importance of the preparation procedure for the strength of the metal-support interaction is discussed. This paper shows that the use of model catalysts to study surface and interface phenomena is relevant for technical heterogeneous metal catalysis
