Boson and fermion dynamics in quasi-one-dimensional flat band lattices

The difference between boson and fermion dynamics in quasi-one-dimensional lattices is studied with exact simulations of particle motion and by calculating the persistent current in small quantum rings. We consider three different lattices which in the tight binding model exhibit flat bands. The physical realization is considered to be an optical lattice with bosonic or fermionic atoms. The atoms are assumed to interact with a repulsive short range interaction. The different statistics of bosons and fermions causes different dynamics. Spinless fermions are easily trapped in the flat band states due to the Pauli exclusion principle, which prevents them from interacting, while boson are able to push each other out from the flat band states

Teaching-learning partnership between nurses and long-term renal dialysis patients undergoing peritoneal dialysis: a qualitative study.

BACKGROUND: People with end-stage kidney disease (ESKD) receiving peritoneal dialysis (PD) have been found to alter their adherence to the renal therapeutic regimen following their initial teaching by PD nurses. Since alterations of adherence have been associated with poor health outcomes, this study focuses on persons receiving PD who rely on support and re-education from their nurses. OBJECTIVES: To explore the teaching-learning partnership between people receiving PD and PD nurses, and to compare and contrast shared perspectives. DESIGN: The study consisted of individual semi-structured interviews of four people receiving PD and three PD nurses, using qualitative content analysis. FINDINGS: Four shared themes and nine sub-themes emerged: motivation was characterised by perceptions of staying healthy to avoid peritonitis pain and to qualify for a transplant . One sub-theme emerged exclusively in the interviewed people receiving PD: motivation to initiate PD through finding meaning in life and situation . The theme acceptance was comprised of diagnosis and choosing to initiate PD and the modification and integration into daily life . The presence of support arose from personal support from family and friends , professional care and understanding of the individual and professional customised and re-iterative education . The evolving partnership was comprised of exposure , personal rapport , and the necessity of working together in order to maintain positive health outcomes. CONCLUSION: The partnership between the PD nurse and people receiving PD for ESKD is crucial for successful health outcomes. Each partnership is unique and evolves over time. A successful partnership requires nurses to modify the educational content and teaching style to best meet the needs of people receiving PD and, most importantly, allow them to feel cared for and supported

Success factors of demand-driven open innovation as a policy instrument in the case of the healthcare industry

Abstract According to the WHO Global Digital Health Strategy 2020–2024, we should advocate people-centred health systems, promote global collaboration and strengthen the governance of global digital health practices. All this requires a new open innovation approach, which means that stakeholders from regional administrations, hospitals, companies and intermediate organisations openly work together towards commonly identified global and regional digital health goals. Although both practice and theory have proven that the open innovation approach is beneficial for companies and end-users, there is still a need for increased understanding of what leads to the success of digital health related to regional competitiveness through the implementation of policies based on people-centred open innovation. This study is a longitudinal case study in which open innovation ecosystem partners (including challengers (healthcare organisation representatives), solvers (companies), funders (policy organisations) and supporters (intermediate organisations) were monitored and analysed in three countries. The focus of the paper is to explore a digital health open innovation ecosystem over the years. The results show that the created demand-driven open innovation model can be used to strengthen the governance of digital health, and to improve communication density and knowledge transfer between the ecosystem actors. The new model is a useful way to make funding structures clearer and to improve the people centricity of digital health solutions. The findings help policy-makers to use open innovation as a policy instrument supporting hospital and company managers to increase understanding of the opportunities of demand-driven open innovation

Family dynamics of child-bearing families in athens, greece: A pilot study

The purpose of this pilot study was to describe family dynamics in Greek families during the third trimester of a low-risk pregnancy with a first or second child.The description is based on Barnhill's framework for healthy family systems. The sample consisted of families expecting their first or second child. Both mothers (n = 160) and fathers (n = 47) participated in the study.The Family Dynamics Measure and a sociodemographic questionnaire were used in data collection. Data on 160 mothers and 47 couples were analyzed. Fathers perceived their families as having greater stability and role reciprocity than mothers. Fathers also reported clearer communication than mothers. There were no statistically significant relationships among family dynamics dimensions, maternal age and parity. Delayed first-time expectant mothers reported greater flexibility than normative first-time expectant mothers. The results provide some useful clues for prenatal care and also for further family dynamics research in Greece. © Wiley Publishing Asia Pty Ltd
