In: FORMakademisk. - Oslo : FORMakademiska. - 1890-9515 .- 1890-9515. ; 16:5, s. 1-21

Journal article (peer-reviewed)abstract
- This paper sheds light on how aesthetic judgments govern actions in education for design literacy and sustainability behaviours. Educational material is examined by asking: (1) What meanings regarding becoming a sustainable consumer are made available to students in the educational material? (2) How are these narratives communicated to change students’ behaviours? The material in question consists of 17 design projects intended to be used in the Swedish school subject, Educational Sloyd. Using a practical epistemological analysis, two ways of becoming a sustainable consumer are identified: to have fun and to feel clever. The paper also shows how social marketing is used as a strategy in communicating how to change student behaviours. In the discussion, we turn to design literacy research to discuss the results from an educational perspective.

Social-spatial network structures among young urban and suburban persons who inject drugs in a large metropolitan area
- 2023
-
In: INTERNATIONAL JOURNAL OF DRUG POLICY. - 0955-3959 .- 1873-4758. ; 122

Journal article (peer-reviewed)abstract
- Background: Recent studies underscore the significance of adopting a syndemics approach to study opioid misuse, overdose, hepatitis C (HCV) and HIV infections, within the broader context of social and environmental contexts in already marginalized communities. Social interactions and spatial contexts are crucial structural factors that remain relatively underexplored. This study examines the intersections of social interactions and spatial contexts around injection drug use. More specifically, we investigate the experiences of different residential groups among young (aged 18-30) people who inject drugs (PWID) regarding their social interactions, travel behaviors, and locations connected to their risk behaviors. By doing so, we aim to achieve a more comprehensive understanding of the multidimensional risk environment, thereby facilitating the development of informed policies.Methods: We collected and examined data regarding young PWID's egocentric injection network and geographic activity spaces (i.e., where they reside, inject drugs, purchase drugs, and meet sex partners). Participants were stratified based on the location of all place(s) of residence in the past year i.e., urban, suburban, and transient (both urban and suburban) to i) elucidate geospatial concentration of risk activities within multidimensional risk environments based on kernel density estimates; and ii) examine spatialized social networks for each residential group.Results: Participants were mostly non-Hispanic white (59%); 42% were urban residents, 28% suburban, and 30% transient. We identified a spatial area with concentrated risky activities for each residential group on the West side of Chicago in Illinois where a large outdoor drug market area is located. The urban group (80%) reported a smaller concentrated area (14 census tracts) compared to the transient (93%) and suburban (91%) with 30 and 51 tracts, respectively. Compared to other areas in Chicago, the identified area had significantly higher neighborhood disadvantages. Significant differences were observed in social network structures and travel behaviors: suburban participants had the most homogenous network in terms of age and residence, transient participants had the largest network (degree) and more non-redundant connections, while the urban group had the shortest travel distance for all types of risk activities.Conclusion: Distinct residential groups exhibit varying patterns of network interaction, travel behaviors, and geographical contexts related to their risk behaviors. Nonetheless, these groups share common concentrated risk activity spaces in a large outdoor urban drug market area, underscoring the significance of accounting for risk spaces and social networks in addressing syndemics within PWID populations.

Synthesis, structure, and bonding of Sc4MgxCu15-Ga-x similar to(7.5) (x=0, 0.5). Two incommensurately modulated scandium substitution derivatives of cubic Mg2Cu6Ga5

Journal article (peer-reviewed)abstract
- The substitution of scandium for magnesium in Mg2Cu6Ga5 (Mg2Zn11-type) yields an irrational superstructure phase that includes the refined compositions, Sc4Mg0.50(2)Cu14.50(2)Ga7.61(2) and Sc4Cu14.76(2)Ga7.51(2)- These crystallize in Cmmm, a = similar to 8.31 angstrom, b = similar to 21.72 angstrom, c = -8.30 angstrom. The structures feature Sc-2 dimers, Cu-6 octahedra, a 3D CuGa (Cu12Ga2) framework, and arachno gallium-centered Cu4Ga6 icosahedra that are condensed into zigzag chains. The arrangement of these building blocks exhibits a topologic relationship to Mg2Cu6Ga5. Further studies reveal that the quaternary compound exhibits incommensurate modulations along a, with q = (0.694, 0, 0). Structure refinements with superspace group Xmmm(a00)000 led to saw-tooth modulations for two fractional or mixed sites that avoid short Cu-Ga distances. Band structure analyses reveal that the Fermi surface and bonding are sensitive to the incommensurately modulated atoms.

Managing transformation, flow and value generation : a solid timber frame housing case
- 2005
-
In: ARCOM. - Salford : Association of Researchers in Construction Management. ; , s. 331-340
-
Conference paper (peer-reviewed)abstract
- A governmental evaluation of the Swedish construction industry indicates the possibility to reduce the production costs of housing through industrialisation, customer orientation and a more efficient construction process. A way to address this is through implementing the concept of lean thinking, which stresses the importance of improving and integrating design and production while eliminating waste. This paper analyses the design process of a recent Swedish solid timber frame housing project by using the concept of lean thinking. The aim is to suggest actions to improve the management of transformation, flow and value generation. For the timber construction process to become more effective (lean) and customer orientated, the timber frame supplier is suggested to increase the information flow and make the flow management more efficient. To establish a better control of the processes in timber housing in particular, the design process must be decomposed into small manageable pieces (time and cost specified) and evaluated within the project team. To increase value generation and make the construction process understood as a generation of value for the client, we think that active clients are the key.

Wideband Array Antenna with Hybrid SIGW and RGW Feeding Network
- 2021
-
In: 2021 International Conference on Microwave and Millimeter Wave Technology, ICMMT 2021 - Proceedings.
-
Conference paper (peer-reviewed)abstract
- In this paper, a 4×4-element linearly-polarized wideband array antenna with a feeding network made of a combination of substrate integrated gap waveguide (SIGW) and ridge gap waveguide (RGW) technologies is proposed. The bowtie dipoles are employed as the radiation elements for the array antenna, and the bandwidth is broadened by using the concept of the tightly coupled array. By employing the hybrid feeding network combining the SIGW with the RGW, a high efficiency can be achieved with a low profile. Based on the simulations by using CST Microwave Studio, the proposed 4×4 array antenna exhibits a relative impedance bandwidth of 34% from 22.7 to 32 GHz, with a maximum gain of 18 dBi.

Swedish exotic vowels in L2 pronunciation
- 2017
-
In: Proceedings of the 8th annual pronunciation in second language learning and teaching conference (ISSN: 2380-9566). - Calgary : University of Calgary. ; , s. 222-227
-
Conference paper (peer-reviewed)abstract
- Learning a new language as an adult is often a hard task, particularly the pronunciation of new speech sounds. Earlier research has shown (e.g., Bannert, 1990; Zetterholm & Tronnier, 2017) that second language learners of Swedish have difficulties learning to pronounce some Swedish vowels, especially the front rounded vowels, and distinguishing them from each other and from unrounded vowels. For intelligible speech, it is of importance that there is an audible distinction in the pronunciation of the different rounded vowels. Otherwise a native listener might misunderstand the speaker referring to the number of minimal pairs with the vowel as the distinctive feature. In comparison with languages around the world, the Swedish vowel inventory is relatively large (Ladefoged, 2005), and some are exotic from a worldwide perspective. These vowels are one of the most difficult pronunciation features of Swedish pronunciation for second language learners to master. The aim of this paper is to provide information about the vowels of Swedish with a focus on rounded vowels that are challenging for L2 learners of Swedish and to present some techniques to facilitate the accurate pronunciation of the exotic vowels.
