Enhancing cultural competence: Trans-Atlantic experiences of European and Canadian nursing students

This paper describes the enhancement of cultural competence through trans-Atlantic rural community experiences of European and Canadian nursing students using critical incident technique (CIT) as the students' reflective writing method. The data generated from 48 students' recordings about 134 critical incidents over a 2-year project were analysed by qualitative content analysis. Five main learning categories were identified as: cross-cultural ethical issues; cultural and social differences; health-care inequalities; population health concerns; and personal and professional awareness. Four emergent cultural perspectives for the health sector that became apparent from the reflections were: health promotion realm; sensitivity to social and cultural aspects of people's lives; channels between the health sector and society; cultural language and stories of local people. CIT was successfully used to foster European and Canadian undergraduate students' cultural reflections resulting in considerations and suggestions for future endeavours to enhance cultural competence in nursing education

Quantum Simulations of One-Dimensional Nanostructures under Arbitrary Deformations

A powerful technique is introduced for simulating mechanical and electromechanical properties of one-dimensional nanostructures under arbitrary combinations of bending, twisting, and stretching. The technique is based on a novel control of periodic symmetry, which eliminates artifacts due to deformation constraints and quantum finite-size effects, and allows transparent electronic structure analysis. Via density-functional tight-binding implementation, the technique demonstrates its utility by predicting novel electromechanical properties in carbon nanotubes and abrupt behavior in the structural yielding of Au7 and MoS nanowires. The technique drives simulations markedly closer to the realistic modeling of these slender nanostructures under experimental conditions.Comment: 9 pages, 8 figures, 1 vide

Fractional Periodicity of Persistent Currents: A Signature of Broken Internal Symmetry

We show from the symmetries of the many body Hamiltonian, cast into the form of the Heisenberg (spin) Hamiltonian, that the fractional periodicities of persistent currents are due to the breakdown of internal symmetry and the spin Hamiltonian holds the explanation to this transition. Numerical diagonalizations are performed to show this explicitely. Persistent currents therefore, provide an easy way to experimentally verify broken internal symmetry in electronic systems.Comment: minor correction
