Towards a regional science academy : A manifesto
- 2016
-
In: Region. - : European Regional Science Association. - 2409-5370. ; 3:1, s. R1-R16
-
Journal article (peer-reviewed)abstract
- This Manifesto provides a joint proposal to create a Regional Science Academy as a think-tank support platform for a strategic development of the spatial sciences. The Regional Science Academy is a strategic spatial knowledge catalyst: it acts as a global intellectual powerhouse for new knowledge network initiatives and scholarly views on regions and cities as vital centrepieces of interconnected spatial systems. This contribution highlights its role and presents various activity plans.

Aging and memory effects in a mechanically alloyed nanoparticle system
- 2007
-
In: Journal of Magnetism and Magnetic Materials. - : Elsevier BV. - 0304-8853 .- 1873-4766. ; 313:2, s. 373-377

Journal article (peer-reviewed)abstract
- Ageing and memory experiments have been performed to explore the non-equilibrium dynamics of the mechanically alloyed nanoparticle system Fe30Ag40W30, which comprises a heterogeneous ensemble of magnetic particles with average moment 102 μB dispersed in a metallic non-magnetic matrix. This system has earlier, from critical slowing down analysis, been reported to enter a spin glass like state at low temperatures [J. A. de Toro et al., Phys. Rev. B 69, (2004) 224407]. The wait time dependence of the magnetic relaxation observed after the application of a weak magnetic field and the memory of the thermal history in the low temperature phase recorded on continuous heating in a weak applied field show similar features as observed in corresponding experiments on canonical spin glasses.

Visualizing Vortex Clusters in the Wake of a High-Speed Train
- 2017
-
In: 2017 IEEE INTERNATIONAL CONFERENCE ON SYSTEMS, MAN, AND CYBERNETICS (SMC). - 1062-922X. - 9781538616451 ; , s. 683-688

Conference paper (peer-reviewed)abstract
- Visualization of fluid flows at a high-Reynolds number (Re similar to 10(5)) presents difficulties for user comprehension due to density and ambiguous interactions between vortices. Prior work has used cluster-based reduced-order modelling (CROM) to analyze the wake of a High-Speed Train (HST) with Re = 86,000. In this paper, we present a novel surface visualization to convey the spatiotemporal changes undergone by clustered vortices in the HST wake. This visualization is accomplished through dimensional reduction of 3D volumetric vortices into 1D ridges, and physics-based feature tracking. The result is 3D surfaces visualizing the behavior of the vortices in the HST wake. Compared to conventional still-image representations, these surfaces allow the user to quickly compare and analyze the two shedding cycles identified via CROM. The spatiotemporal differences of the primary vortices in these shedding cycles provide analytic insight to influence the aerodynamics of the HST.

How Crucial is Distance to Jobs for Ethnic Minorities? Old Question – Improved Answer
- 2010
-
In: Journal of Economic Geography. - : Oxford University Press (OUP). - 1468-2702 .- 1468-2710. ; 10, s. 389-422
-
Journal article (peer-reviewed)abstract
- We study the impact of job proximity on individual employment and earnings. The analysis exploits a Swedish refugee dispersal policy to obtain exogenous variation in individual locations. Using very detailed data on the exact location of all residences and workplaces in Sweden, we find that having been placed in a location with poor job access in 1990–1991 adversely affected employment in 1999. Doubling the number of jobs in the initial location in 1990–1991 is associated with 2.9 percentage points higher employment probability in 1999. Considering that the 1999 employment rate was 43% among the refugees, this is a considerable effect. The analysis suggests that residential sorting leads to underestimation of the impact of job access.

Keeping Track of My Drinking : Patient Perceptions of Using Smartphone Applications as a Treatment Complement for Alcohol Dependence
- 2024
-
In: Substance Use & Misuse. - : Taylor & Francis. - 1082-6084 .- 1532-2491. ; 59:2, s. 291-299
-
Journal article (peer-reviewed)abstract
- Background: Alcohol dependence is common, yet highly undertreated. Smartphone applications (apps) have potential to enhance treatment accessibility and effectiveness, however evidence is limited, especially studies focussing on user experiences. The aim was to describe patient perceptions on the usability and acceptability of self-monitoring apps provided as treatment complement for alcohol dependence.Methods: Individual semi-structured interviews were conducted through video or phone calls with 21 participants, recruited from a randomized controlled trial at a dependency clinic in Stockholm. The participants had used two specific apps for self-monitoring consumption ("Glasklart" and "iBAC") during 12 wk prior to the interviews. Data was analyzed using Qualitative Content Analysis.Results: Two domains were identified: 1) Smartphone applications as facilitators to treatment, and 2) Barriers to smartphone application use. Using apps within the treatment context was believed to increase the accuracy of the reported consumption. Participants became more aware of their alcohol problem and described the apps as reinforcers that could increase both the motivation to change and the focus on the problem and commitment to treatment. The apps were further described as helpful to control alcohol consumption. However, app usage was constrained by technical problems, unfit app-specific features and procedures, and alcohol-related shame and stigma.Discussion and Conclusions: Self-monitoring alcohol apps have several beneficial features that can help assess, track, and control alcohol consumption, and improve communication with clinicians. The results indicate they can be useful complements to treatment for patients with alcohol dependence, but their use can be limited by different, foremost technical, issues. Smartphone applications for self-monitoring of alcohol consumption may help provide accurate data, increase consumption awareness, focus, motivation, and perceived control; Smartphone applications for self-monitoring of alcohol consumption are considered helpful complements to alcohol treatment; The use of smartphone applications for self-monitoring of alcohol consumption can be constrained by technical problems, and unfit app-specific features and procedures.
