- In 2015, the Norwegian Broadcasting Corporation (NRK) released a new youth series, Skam, which was acclaimed for its accurate portrayal of Norwegian teenagers but, above all, for its distribution as a transmedia narrative spreading content across several platforms. Through focus-group interviews, this article investigates how Swedish Skam viewers took part in the content and perceived the role and relation between the platforms. While the interviewees followed Skam in different ways, they nevertheless accepted and appreciated the transmedia format. While they argued that the core content needed to be video based, other content was also seen as a natural part of the series and essential in building the narrative. Furthermore, the idea of contemporary media consumption as being less constrained by time and space was partly contradicted. Especially real-time content and discussions with peers motivated the participants to abide by a new kind of TV schedule, reminiscent of TV viewing practices of the past.

Multivariate analysis of the effect of biodiesel-derived contaminants on V2O5-WO3/TiO2 SCR catalysts

- This study investigates the effect of biodiesel-derived contaminants on vanadia-based NH3-SCR catalysts in heavy-duty exhaust aftertreatment. The aim was to study, not only the effect of single contaminants on the catalyst performance, but also of possible interaction effects between poisons.The effect of six potential catalyst poisons (Na, K, Mg, P, S and Zn) was evaluated using an experimental design and multivariate data analysis. Monolithic V2O5-WO3/TiO2 catalysts were subjected to accelerated laboratory-scale aging, where the six contaminants were fed simultaneously using a wet impregnation method. In addition to NOx conversion tests, the catalysts were characterized by means of ICP-OES, SEM-EDX, XPS, N2 physisorption and NH3-TPD. The lab-aged samples were compared to fresh and vehicle-aged catalysts.The accelerated aging method showed good reproducibility and gave rise to surface compounds similar to those found in vehicle-aged catalysts. Despite plausible differences regarding penetration depth of the contaminants into the walls of the catalyst, the aging method appears to be an efficient way to point out significant chemical poisons.The model obtained from the experimental design was found to correlate well with the experimental data and can therefore be used to predict effects of the various poisons and poison interactions. Significant effects on the NO. x conversion were found for P, S, Na, Mg and K as well as for the interactions P. ×. Na, P. ×. K and S. ×. Na. A poisoning effect was found for Mg, Na, K, P. ×. K, and P. ×. Na, where Na and K exhibited the strongest poisoning effect. The deactivating effect of alkali was lowered in the presence of phosphorus and sulfur, which is explained by the formation of phosphates and sulfates, preventing the interaction of the alkali metals with the vanadia active sites.

Self-Schema, Attachment Style, and Treatment Outcome of Patients in an Opiate Maintenance Treatment Unit
- 2021

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to explore self-schemas and attachment style among patients in a methadone or buprenorphine maintenance treatment program of opiate dependence, in relation to treatment outcome (relapse in substance use). The study included 84 patients (21 women and 63 men) in a psychiatric clinic in Malmö, Sweden, providing maintenance treatment of opiate dependence. Three self-report instruments were employed, Young Schema Questionnaire Short version (YSQ-S) and Young Parenting Inventory (YPI) for studying self-schemas and Experiences in Close Relationships–Relationship Structures questionnaire (ECR-RS) for studying attachment style. Demographical data and relapse in substance abuse were registered. The study demonstrated, unsurprisingly, that an insecure attachment style was more common in the group of patients compared to available general population reference data. Significant correlations were found between attachment style and core beliefs about the self (self-schemas). Memories of parenting experiences from childhood (YPI) showed correlations with ongoing self-schemas (YSQ-S). Treatment outcome, defined as relapses in substance abuse, was associated to a minor degree with self-schemas but showed no correlation with attachment style. Patients who did not work or study had more maladaptive self-schemas and insecure attachment style, and a higher incidence of relapse in abuse than patients who were working or studying.

Detection of the fungicide transformation product 4-hydroxychlorothalonil in serum of pregnant women from Sweden and Costa Rica
-
Ingår i: Journal of Exposure Science & Environmental Epidemiology. - 1559-064X.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: 4-hydroxychlorothalonil (HCT, R182281), a transformation product of the fungicide chlorothalonil, was recently identified in human serum and breast milk. There are indications that HCT may be more toxic and environmentally persistent than chlorothalonil.OBJECTIVE: Our aim was to investigate serum concentrations of HCT in pregnant women in Sweden and Costa Rica.METHODS: We developed a quantitative analytical method for HCT using liquid chromatography tandem mass spectrometry. We measured HCT in 1808 serum samples from pregnant women from the general population in Sweden (1997-2015) and in 632 samples from 393 pregnant women from an agricultural population in Costa Rica (2010-2011). In Swedish samples, we assessed time trends and investigated seasonality. In the Costa Rican samples, we evaluated variability between and within women and explanatory variables of HCT concentrations.RESULTS: HCT was detected in all serum samples, and the limit of detection was 0.1 µg/L. The median HCT concentration in the Swedish samples was 4.1 µg/L (interquartile range [IQR] of 2.9 - 5.8 µg/L), and 3.9 times higher in the Costa Rican samples (median: 16.1 µg/L; IQR: 10.6 - 25.0 µg/L). We found clear seasonal variation with higher concentrations in the first half of each year among Swedish women. In the Costa Rican study, women working in agriculture and living near banana plantations had higher HCT concentrations, whilst higher parity and having a partner working in agriculture were associated with decreased HCT, and no clear seasonal pattern was observed.IMPACT STATEMENT: For the first time, this study quantifies human exposure to the fungicide chlorothalonil and/or its transformation product 4-hydroxychlorothalonil (HCT, R182281) and finds higher serum concentrations in women from a tropical agricultural setting as compared with women from the general population in Sweden.

Fel att offra betesmark i Sverige av klimatskäl

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Ambitionen att minska köttkonsumtionen är lovvärd men riskerar att slå hårt mot den biologiska mångfalden och ekosystemtjänster. Om våra naturbetesmarker försvinner kan vi inte leva upp till FN:s internationella hållbarhetsmål och våra egna svenska miljömål som vi förbundit oss att jobba mot, skriver ett flertal forskare.

Twang! : A physically derived synthesis model for the sound of a vibrating bar
- 2022
-
Ingår i: AES Europe Spring 2022. - : Audio Engineering Society. ; , s. 76-85
-
Konferensbidrag (refereegranskat)abstract
- A physically derived synthesis model of the sound generated when a ruler is twanged while hanging over the edge of a solid surface is presented. This is a sound effect used in movies, TV, theatre performances and cartoons. The model is derived from the Euler-Bernoulli equation, offering the user a set of physical parameters to control ruler length as well as the material properties. Perceptual evaluation indicates that the model can be perceived as realistic as a recorded ruler twang as well as being able to replicate sounds of similar quality as an alternative synthesis model.
