- We introduce the set of quasi-Herglotz functions and demonstrate that it has properties useful in the modelling of non-passive systems. The linear space of quasi-Herglotz functions constitutes a natural extension of the convex cone of Herglotz functions. It consists of differences of Herglotz functions and we show that several of the important properties and modelling perspectives are inherited by the new set of quasi-Herglotz functions. In particular, this applies to their integral representations, the associated integral identities or sum rules (with adequate additional assumptions), their boundary values on the real axis and the associated approximation theory. Numerical examples are included to demonstrate the modelling of a non-passive gain medium formulated as a convex optimization problem, where the generating measure is modelled by using a finite expansion of B-splines and point masses.

- The aim was to describe, from the newly registered nurses’ perspective, specific events when using their pedagogical knowledge in their everyday clinical practice. The design was qualitative and the critical incident technique was used. Data was collected via interviews with ten newly registered nurses who graduated from the same University program 10 months earlier and are now employed at a university hospital.Two categories emerged in the analyses. The first category was “Pedagogical methods in theory” with the sub-categories Theory and the application of the course in practice, Knowledge of pedagogy and Information as a professional competence. The second category was “Pedagogical methods in everyday clinical practice” with sub-categories Factual knowledge versus pedagogical knowledge, Information and relatives, Difficulties when giving information, Understanding information received, Pedagogical tools, Collaboration in teams in pedagogical situations, and Time and giving information. By identifying specific events regarding pedagogical methods the findings can be useful for everyone from teachers and health-care managers to nurse students and newly registered nurses, to improve teaching methods in nurse education.

Does country-level gender equality explain individual risk of intimate partner violence against women? A multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) in the European Union
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Gender equality is widely accepted as an important explanatory factor for the occurrence of intimate partner violence (IPV) against women. However, the relationship is not straightforward, as high country-level gender equality is not always associated with lower IPV prevalence. We apply 'multilevel analysis of individual heterogeneity and discriminatory accuracy' (MAIHDA) to (i) quantify the extent to which the country of residence determines individual risk of IPV and (ii) investigate the association between country-level gender equality and individual experience of IPV, and to which extent this association explains the observed between-country differences. Using data from the 2012 European Union Agency for Fundamental Rights survey on violence against women we applied MAIHDA to analyse experiences of physical and sexual IPV among 42 000 women living in the EU. We fitted three consecutive models, and calculated specific individual contextual effects (measures of association) as well as the general contextual effects (measures of variance) and the discriminatory accuracy (DA). Our findings show that the relationship between experiences of IPV and country-level gender equality is weak and heterogeneous. The general contextual effect is small and the DA is low, indicating that country boundaries are rather irrelevant for understanding the individual risk of IPV. Findings from the present study do not imply that that gender equality is unimportant in relation to IPV, but rather that information on country of residence or country-level gender equality does not discriminate very well with regards to individual experiences of IPV in cross-national comparisons.

Understanding User Involvement in Research in Aging and Health
- 2019
-
Ingår i: Gerontology and Geriatric Medicine. - : SAGE Publications. - 2333-7214. ; 5
-
Tidskriftsartikel (refereegranskat)abstract
- User involvement in research is advocated as an avenue for efficient societal developments. In this article, we identify potentials, problems, and challenges related to research on aging and health, and identify and illustrate research priorities using an evolving research program as an example. Involving user representatives in the development phase, the UserAge program engages researchers at four universities in Sweden. The program builds upon previous and ongoing research with user involvement. The goals are to maximize the impact of user involvement, enhance the execution of high-quality research, increase the knowledge about what difference user involvement can make, and evaluate the impact of research about and with user involvement. Taken together and communicated in the international scientific community as well as in a wide range of public arenas, the empirical results, capacity-building, and modeling efforts of UserAge will have an impact not only on the present situation but also on the future.

Multiple rapid automatic naming measures of cognition: Normal performance and effects of aging
- 2004

Tidskriftsartikel (refereegranskat)abstract
- Rapid automatic naming tasks are clinical tools for probing brain functions that underlie normal cognition. To compare performance for various stimuli in normal subjects and assess the effect of aging, we administered six single-dimension stimuli (color, form, number, letter, animal, and object) and five dual-dimension stimuli (color-form, color-number, color-letter, color-animal, and color-object) to 144 normal volunteers who ranged in age from 15 to 85 years. Rapid automatic naming times for letters and numbers were significantly less than for forms, animals, and objects. Rapid automatic naming times for color-number and color-letter stimuli were significantly less than for color-form, color-animal, or color-object stimuli. Age correlated significantly with rapid automatic naming time for each single-dimension stimulus and for color-form, color-number, color-animal, and color-object stimuli. Linear regression showed that rapid automatic naming times increased with age for aggregated color stimuli, aggregated single-dimension stimuli, and aggregated dual-dimension stimuli. This age effect persisted in subgroups less than 60 years of age and greater than 60 years of age. We conclude that normal performance time is dependent on the task, with letter and number stimuli eliciting most rapid responses, and that most rapid automatic naming times increase with age.

Integrating supply chains for emergencies and ongoing operations in UNHCR
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Humanitarian organizations (HOs) often base their warehouse locations on individuals' experience and knowledge rather than on decision-support tools. Many HOs run separate supply chains for emergency response and ongoing operations. Based on reviews of humanitarian network design literature combined with an in-depth case study of United Nations High Commissioner for Refugees (UNHCR), this paper presents a warehouse location model for joint prepositioning that incorporates political and security situation factors. Although accessibility, co-location, security, and human resources are crucial to the practice of humanitarian operations management, such contextual factors have not been included in existing network optimization models before. We found that when quantified, and modeled, such factors are important determinants of network configuration. In addition, our results suggest that joint prepositioning for emergency response and ongoing operations allows for expansion of the global warehouse network, and reducing cost and response time.

- We demonstrate an artificial three-dimensional (3D) electrical active human neuronal network system, by the growth of brain neural progenitors in highly porous low density electrospun poly-ε-caprolactone (PCL) fiber scaffolds. In neuroscience research cell-based assays are important experimental instruments for studying neuronal function in health and disease. Traditional cell culture at 2D-surfaces induces abnormal cell–cell contacts and network formation. Hence, there is a tremendous need to explore in vivo-resembling 3D neural cell culture approaches. We present an improved electrospinning method for fabrication of scaffolds that promote neuronal differentiation into highly 3D integrated networks, formation of inhibitory and excitatory synapses and extensive neurite growth. Notably, in 3D scaffolds in vivo-resembling intermixed neuronal and glial cell network were formed, whereas in parallel 2D cultures a neuronal cell layer grew separated from an underlying glial cell layer. Hence, the use of the 3D cell assay presented will most likely provide more physiological relevant results.

Bokkapitel (refereegranskat)abstract
- The aim of the present study is twofold: to explore the assessment andintervention practices of Swedish practitioners (mainly Speech and LanguageTherapists: SLTs) for multilingual children with Developmental LanguageDisorders (DLD) and to explore to which extent they perceive themselves asconfident with respect to assessment and intervention. The data comes fromthe Swedish part of the survey by the European research network (COST1406),including data from 35 countries. In total, 101 practitioners in Swedenanswered an online survey. Most of the respondents were female, had amaster’s degree, Swedish as their first language (L1), and used only onelanguage in their professional role. All the practitioners answered the firstsection, 45 of whom also answered questions regarding which languages theyuse in assessment and intervention with multilingual children. A majority of theparticipants reported that they encourage parents to use the minority languagewhen communicating with their child at home. The results indicate a contextspecific DLD intervention approach in which Swedish practitioners tend toemphasize the importance of native language-usage at home. However, due tothe amount of missing data, methodological issues need to be taken intoconsideration.
