Abstract Venous blood pressure measurements were made by direct cannulation of the median antecubital vein. Measurements were taken at rest, during a 5-minute exercise on the bicycle ergometer, and during a 15-minute recovery period. The range of resting pressure was from 73 to 169 mm. water, with a mean pressure of 120 mm. water. The pressure during exercise increased in every case and was maintained throughout the exercise. The average increase was 118 mm. water, representing an increase of 95 percent. Venous pressure during recovery showed a very rapid drop during the first three minutes and then exhibited a progressively slower decline until a constant level was reached. 相似文献
Quantum chemistry is based on the solution of the Schrödinger equation for a molecule. From starting data on the positions and nature of constituent atoms information is provided about the energy of the molecule and its electronic properties. The former can indicate what shapes drugs can adopt in binding to pharmacological receptors whilst electronic details, when compared using computer graphics, may highlight the factors responsible for biological activity. These techniques are beginning to show real successes in the design of drug molecules. 相似文献
The Children and Families Act (2014) placed a statutory responsibility on local authorities in the UK to establish a virtual school headteacher with the role of championing the education of all children looked-after within that authority. The current research was designed to illuminate how virtual schools are currently supporting educational outcomes for children looked-after, not only through educational interventions, but also through supporting broader psychological factors that might impact on attainment such as attachment, relationships and mental health. Virtual school headteachers from 29 local authorities completed an online survey about the services they provided to three target groups—children looked-after, foster carers and schools—with a particular focus on the transition years from primary to secondary school, which have been identified as being a difficult time for children looked-after. Using inductive thematic analysis, four overarching themes to service provision were identified: enhanced learning opportunities, specific transition support, well-being and relationships, and raising awareness. Direct work, interprofessional working and the development of supportive environments, particularly guided by attachment theory, were identified as important areas of practice. Practice is discussed in relation to resilience and ecological systems theory and suggestions for future research are identified.
An important purpose of higher social work education is to guide students to acquire and develop social-communicative competencies.
The purpose of this study was to investigate the role students’ personality characteristics, self-perceived communicative
competence and learning conceptions play in the acquisition and development of social-communicative competencies. We designed
and tested a hypothetical model on the student-related variables – self-perceived communicative competence, learning conceptions
and reported learning activities regarding communication – in relation to performance scores. We were interested in developmental
trends in the above mentioned variables. We also wanted to gain insight into the relationships among the variables. The study
was set up according to a longitudinal, within-subjects design in order to study intra-individual changes. One-hundred and
twenty-three first-year social-work students participated in this study. Many changes were found in students characteristics,
reported deployed learning activities and study results during their first academic year. Except for confidence in “showing
sympathy”, which was already relatively high at the beginning of the study, all scores on aspects of students’ self-perceived
social-communicative competence increased. Assessment scores on comparable communication tests also increased significantly.
Extraversion and emotional stability were the only two personality characteristics, which seemed rather stable. Agreeableness
decreased while autonomy increased continuously during the first academic year. It seemed to be possible to set up a model, which may
serve as a starting point for further research into the development of social-communicative competence. 相似文献
