Frequency and temperature dependence of the electrical conductivity of KTaO3; Li and PbTiO3; La, Cu: Indication of a low temperature polaron mechanism

2008

Abstract Recently, the concept of polarons has again been at the focus of solid-state research, as it can constitute the basis for understanding the high-temperature superconductivity or the colossal magnetoresistance of materials. More than a decade ago there were some indications that polarons play an important role in explaining low temperature maxima in imaginary part of the dielectric constant e ″ ( T ) in ABO3 perovskites. In the present work we report the ac electrical conductivities of KTaO3; Li and PbTiO3; La, Cu and their frequency and temperature dependence. The real part of the complex ac conductivity was found to follow the universal dielectric response σ ′ ∝ ν s . A detailed t…

Dignity, Dependence, and Relational Autonomy for Older People Living in Nursing Homes

2015

Dignity is a core concept in nursing care. In earlier theories on dignity, close links have been drawn between dignity and autonomy, and autonomy has been closely related to independence. These traditional understandings of dignity and autonomy may be challenged when an individual moves into a nursing home. Our findings show that negative views about dependence, institutional frames and structures in the nursing home, and the attitudes and actions of healthcare personnel may diminish independence and lead to a lack of autonomy. Each of these areas can be experienced as a serious threat to the residents' dignity. Findings are interpreted and discussed in the light of a theory of relational a…

“It’s More Than Just Exercise”: Tailored Exercise at a Community-Based Activity Center as a Liminal Space along the Road to Mental Health Recovery an…

2021

Mental health care policies call for health-promoting and recovery-oriented interventions, as well as community-based programs supporting healthier habits. The purpose of this study was to explore how individuals facing mental health challenges experienced participating in tailored exercise at a community-based activity center, and what role tailored exercise could play in supporting an individual’s process of recovery. Data were collected through in-depth interviews with nine adults experiencing poor mental health who engaged in exercise at the activity center. Interviews were audio-recorded, transcribed verbatim and analyzed using systematic text condensation. Participants spoke about the…

Linking Disaster Risk Reduction and Healthcare in Locations with Limited Accessibility: Challenges and Opportunities of Participatory Research

2020

Disaster risk reduction and healthcare support each other, including the mitigation of further harm after illness or injury. These connections are particularly relevant in locations which have permanent or temporary limited accessibility. In these circumstances, people are required to be self-sufficient in providing emergency and long-term healthcare with limited resources. Planning and preparing to mitigate further harm after illness or injury from disasters (disaster risk reduction) must include people living and working in locations with limited accessibility, meaning that participatory research can be used. The challenges and opportunities of enacting participatory research in such cont…

Why do Norwegian nurses leave the public health service to practice CAM?

2009

Accepted version of an article published in Complementary Therapies in Clinical Practice, 15 (2009), 147-151 This paper explores a number of issues associated with the recent increase in nurses choosing to leave the Norwegian health care system in order to become independent practitioners of complementary and alternative medicine (CAM). The paper suggests that in Norway, nurses perceive medical hegemony continues to persist. Nurses perceive restrictions in their ability to develop their professional roles and status. CAM would appear to offer many nurses, the opportunity to develop their clinical skills in an autonomous, egalitarian and more holistic environment.

Determining a Random Schrödinger Operator : Both Potential and Source are Random

2020

We study an inverse scattering problem associated with a Schr\"odinger system where both the potential and source terms are random and unknown. The well-posedness of the forward scattering problem is first established in a proper sense. We then derive two unique recovery results in determining the rough strengths of the random source and the random potential, by using the corresponding far-field data. The first recovery result shows that a single realization of the passive scattering measurements uniquely recovers the rough strength of the random source. The second one shows that, by a single realization of the backscattering data, the rough strength of the random potential can be recovered…

Using ICT training as an arena for intergenerational learning experience. A case study

2014

Published version of a paper from the Scandinavian Conference on Health Informatics; August 22; 2014; Grimstad; Norway In Norway; the responsibility of citizens’ e-inclusion services relies on municipalities through the administration of se-lected electronic health information and services; these insti-tutions face the challenge of educating to use these health systems. In the case of ICT-illiterate people; the questions about what is the necessary ICT knowledge for basic use and how this content should be pedagogically delivered arose. This paper presents a pioneer intergenerational model for ICT education; in which young generations teach the basics of ICT use to elderly people without IC…

Refrigeration bound of heat-producing cylinders by superfluid helium

2019

In this paper we go ahead in our studies on refrigeration of nanosystems by superfluid helium, as an appealing subject for future applications to computers or astronautical precision nanodevices. We first recall the effective thermal conductivity in laminar counterflow superfluid helium through arrays of mutually parallel cylinders and we discuss the conditions for the appearance of quantum turbulence around the heat-producing cylinders. We then consider the cooling of an array of heat-producing cylindrical nanosystems by means of superfluid-helium counterflow. We discuss the upper bound on heat removal set by avoidance of quantum turbulence and avoidance of phase transition to normal He I,…

¿Proveer justicia u oprimir a los pueblos? La acción de los corregedores de las Azores en el periodo moderno

2020

En Portugal, los corregedores han sido presentados por la historiografía tradicional como uno de los pilares del proceso de centralización política que había tenido lugar en el reino portugués a partir del final de la Edad Media. Esta interpretación ha sido corregida en las últimas décadas por nuevas investigaciones e interpretaciones. En los territorios portu- gueses de ultramar, la distancia amplió algunos de los “obstáculos fácticos” (según Antonio Manuel Hespanha) que hacían difícil, si no imposible, la concreción de cualquier proyecto centralizador. El caso azoriano es de esto un buen ejemplo. En este artículo, además de una síntesis de los poderes de los corregedores…
