- Climate change is often considered as a looming apocalypse in the media and its impacts on the cryosphere are increasingly visible in the Arctic region. This apocalyptic future of the Arctic relates to a set of narratives associated with the Anthropocene, wherein snowy landscapes, glaciers and polar bears have disappeared. This has led to a trend called last chance tourism, which has become an evolving economic opportunity for tourism operators and local communities. In this conceptual article we propose an alternative vision for Arctic tourism development referred to as "post-Arctic tourism". In order to illustrate the idea, we utilize Finnish Lapland (Arctic Finland) as an example based on existing literature. It is argued that post-Arctic tourism may be based on so-called dark tourism practices if the used and circulated hegemonic representations of the Arctic remain locked in cryospheric- and traditional winter-based imaginaries. This scenario is supported by a social spatialization process called "Arctification", associated with active attempts to maintain the cryospheric gaze. It is therefore critical for tourism businesses, regions and tourism-dependent communities to rethink and re-invent their Arctic narratives, through "de-Arctification" strategies, allowing for a plurality of tomorrows and for Arctic tourism to become more sustainable and ethical.

Onward Migration and Transnationalism : What Are the Interconnections?
- 2023

Ingår i: Onward Migration and Multi-Sited Transnationalism. - Cham : Springer. - 9783031125027 - 9783031125058 - 9783031125034 ; , s. 1-22

Bokkapitel (refereegranskat)abstract
- This introductory chapter sets the scene for the book. It defines onward migration as a migration trajectory that involves extended stays in two or more destination countries and distinguishes it from competing and overlapping terms like stepwise and transit migration. Onward migration is a growing phenomenon within overall global migration dynamics, although statistics to document the scale and trends of this type of migration are scarce. The main aim of the chapter is to examine how onward migration and transnationalism are connected. This is achieved both by reference to a range of existing literature and by citing evidence from the succeeding chapters in the volume. We demonstrate both how transnationalism can shape onward migration and, the reverse, how different onward migration trajectories may result in different forms of transnationalism. In this latter context, we identify inter-generational, split, widening and re-routed transnationalism, again drawing on examples both from the book and from the wider literature. The final section of the chapter consists of a methodological discussion on the practicalities of researching onward migration and multi-sited transnationalism, in which the technique of multi-sited ethnography is discussed, critiqued and modified.

- An experimental analysis of the fire behavior of stone wool composites with stainless steel and gypsum plasterboard linings was performed. The focus was to characterize the micro-scale behavior of stone wool, and identify the main processes occurring in stone wool composites when exposed to heat. Thermogravimetric analysis was applied to two different wools with varying densities and binder content in air and nitrogen atmospheres at 5, 10, and 20 K/min. Results show a low percentage of mass loss that could be linked to the low fraction of organic binder contained in the wool. Intermediate-scale composite assemblies were tested using the Heat-Transfer Inducing Rate System (H-TRIS). Specimens were composed of stainless steel-stone wool, and gypsum plasterboard-stone wool. Tests were performed at (1) constant low incident heat flux (7 kW/m2), (2) constant high incident heat flux (60 kW/m2), and (3) simulated parametric incident heat exposure. The results of these tests help to identify the relevant phenomena that should be taken into account when modelling building assemblies with stone wool cores (i.e. pyrolysis and combustion of the binder, water transport through the cross-section, and burning of paper).

- Ternary poly(N-isopropylacrylamide)/poly(2-alkyl-2-oxazoline)/poly(2-hydroxyethy l methacrylate) (PNIPAAm/PROZO/PHEMA) hydrogels were prepared by the free-radical copolymerization of N-isopropylacrylamide (NIPAAm), 2-hydroxyethyl methacrylate (HEMA), and poly(2-alkyl-2-oxazoline) (PROZO) multifunctional macromonomers. The resulting polymeric materials were characterized by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), as well as by equilibrium swelling experiments. All synthesized hydrogels display temperature sensitivity in the 28-38 degrees C range. A high rate of response was registered as compared to that of materials based only on PNIPAAm. The swelling-deswelling peculiar behavior was related to the chemical composition (hydrophile/hydrophobe balance), the length of the inserted PROZO sequence, and inner morphology, an aspect which points on its possible control by synthesis. It was evidenced that the architecture of the resulting porous materials has a high order degree, emerging from the self-assembling of the microgel particles, which provided numerous, nearly uniform, large water release channels.

- Background Carrying the cyclin-dependent kinase inhibitor 2A (CDKN2A) germline mutations is associated with a high risk for melanoma. Penetrance of CDKN2A mutations is modified by pigmentation characteristics, nevus phenotypes, and some variants of the melanocortin-1 receptor gene (MC1R), which is known to have a role in the pigmentation process. However, investigation of the associations of both MC1R variants and host phenotypes with melanoma risk has been limited. Methods We included 815 CDKN2A mutation carriers (473 affected, and 342 unaffected, with melanoma) from 186 families from 15 centers in Europe, North America, and Australia who participated in the Melanoma Genetics Consortium. In this family-based study, we assessed the associations of the four most frequent MC1R variants (V60L, V92M, R151C, and R160W) and the number of variants (1, ≥2 variants), alone or jointly with the host phenotypes (hair color, propensity to sunburn, and number of nevi), with melanoma risk in CDKN2A mutation carriers. These associations were estimated and tested using generalized estimating equations. All statistical tests were two-sided. Results Carrying any one of the four most frequent MC1R variants (V60L, V92M, R151C, R160W) in CDKN2A mutation carriers was associated with a statistically significantly increased risk for melanoma across all continents (1.24 × 10(-6) ≤ P ≤ .0007). A consistent pattern of increase in melanoma risk was also associated with increase in number of MC1R variants. The risk of melanoma associated with at least two MC1R variants was 2.6-fold higher than the risk associated with only one variant (odds ratio = 5.83 [95% confidence interval = 3.60 to 9.46] vs 2.25 [95% confidence interval = 1.44 to 3.52]; P(trend) = 1.86 × 10(-8)). The joint analysis of MC1R variants and host phenotypes showed statistically significant associations of melanoma risk, together with MC1R variants (.0001 ≤ P ≤ .04), hair color (.006 ≤ P ≤ .06), and number of nevi (6.9 × 10(-6) ≤ P ≤ .02). Conclusion Results show that MC1R variants, hair color, and number of nevi were jointly associated with melanoma risk in CDKN2A mutation carriers. This joint association may have important consequences for risk assessments in familial settings.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Simulation enhanced interprofessional education (SIPE) is a valuable pedagogical approach in health education. SIPE learning environments face many challenges but remain understudied. This study seeks to examine how students from different disciplines address issues related to knowledge and professional identity development within a SIPE learning environment and whether their conceptualizations of their own performances coincide with those of their educators. Data from development plans composed by medical as well as nursing students (n=90) engaging in a SIPE experience as well as from a facilitator survey (n=13) were analyzed using manifest inductive content analysis. The analysis was informed by actor network theory and Schön’s reflection on action model. The results showed that , students reflected on their performance in relation to personal attributes, other team members as well as the surrounding environment. They also reflected on the consequences of their actions and future professional growth. There were observable intergroup differences in terms of knowledge enactment. Facilitators’ and students’ perceptions of performance were mostly aligned. Leadership issues were problematic for students as well as facilitators. In general, the student’ engagement in SIPE helped them to face their professional strengths/ weaknesses and to develop a prototype of their professional identity. However, further work is needed to improve the design of SIPE environments and provide adequate support to students as well as facilitators. The findings of this study have several implications for education, professional practice as well as for future empirical work.

- Recent advances in the understanding of the mammalian visual cortex have led to new approaches for image processing techniques. As a result of this, computer simulations using the proposed visual cortex model have become very useful in the field of image processing. Models of this kind have the ability to efficiently extract image segments, edges and texture. They operate by generating a set of pulse images (images with binary pixels) for a static input. These pulse images display synchronized activity of neighboring neurons, and it is these images in which the information about segments, edges and texture are displayed. Pulse image generation is dependent on autowaves that travel throughout the image. In order to extend pulse image processing to multidimensional data (i.e., data cubes), the autowaves are designed to expand in all of the cube's dimensions. In this fashion, pulse cubes can be created and the same analysis techniques that have been applied to two-dimensional pulse images can be applied to pulse image cubes. This paper examines and discusses multidimensional pulse image analysis applied to three-dimensional (3D) chemical structural data of 17 beta-estradiol.

The hidden boundaries of everyday places : Migrant women, Homeplace and the spatial practices of a small Swedish town
- 2014

Tidskriftsartikel (refereegranskat)abstract
- This article presents a project that focuses on the multiple ways recently arrived migrant women position themselves, and are positioned, in relation to an urban community in a medium-sized town in central Sweden. The research draws on theories of place and social relationships in order to analyse how accessibility of place is structured and explores the tensions in the production of places. Special attention is paid to variations in narratives collected from participants about living in the town and to how the narratives influence the migrants' experiences of everyday places. The results shed light on the importance of social boundaries and of weak hegemonic relationships in generating a sense of homeplace, the ways our informants construct places in their everyday lives, and actions - or inactions - that result from ways that everyday places are constructed.
