Tidskriftsartikel (refereegranskat)abstract
- This article aims to discuss changes in attitudes towards immigrants in Sweden from 2015 onwards, based on the results of the longitudinal Diversity Barometer studies from 2005-2014, 2016 and 2018. The Diversity Barometer studies are based on a national, representative, and randomly selected sample from the Swedish population, with a new sample selected each time. We have analyzed the changes from a sociological perspective, using theories such as contact theory and group conflict theory. The results show an increase in negative attitudes towards ethic and cultural diversity generally, and towards immigrants specifically. Diversity in culture and religion – especially towards Islam – is more negatively perceived as compared to diversity in the work domain. Societal groups with extensive experience from contact with foreigners, those who identify themselves as women, those who are more educated, younger people and city dwellers, have all a more positive attitude towards diversity than others.

Forskningsöversikt (refereegranskat)abstract
- he aim of this article is to elucidate and discuss the results of the 2016 Diversity Barometer (Mångfaldsbarometern) and compare these results with those obtained from ten years of the longitudinal Diversity Barometers for 2005?2014. An additional aim is to demonstrate whether and how Swedish people?s experiences of and attitudes toward people with a foreign background and ethnic diversity have changed.A random sample of the Swedish population took part in the annual study, which was carried out in the form of a nationwide postal survey. The results show that negative attitudes toward ethnic and cultural diversity in general, and migrant population in particular, have increased to some extent and with respect to certain issues. Views on diversity in relation to culture and religion ? especially Islam ? were more negative than views on diversity in relation to work. Those who have larger experience of contact with foreigners show a more positive attitude toward diversity compared with those with limited experience and contact. Individuals who have higher education, those who identify themselves as female, younger persons and those living in large cities are more positive than other groups. In our analysis of the empirical data, we proceeded from a social work perspective and applied contact theory and group conflict theories relating attitudes to group position.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The present study, one of the first to look at COVID-19 and coping in Iran, aimed at mapping, describing and understanding the coping methods academics employ as protective resources to deal with the psychological challenges and social isolation during the COVID-19 pandemic. We specifically aimed at identifying the meaning-making coping methods used and understanding the influence of culture. The guiding research question has been: Are there differences in meaning-making coping methods by gender, age group, work/student status, and place of residence?Design: The study, which used convenience sampling, was a quantitative inquiry. It employed a modified version of the RCOPE scale among faculty/staff members and students in Iran (n = 196, 75% women).Results: The most frequently used coping method among all subgroups of the study sample was thinking that life is part of a greater whole, followed by praying to Allah/God. The least used coping methods were the negative religious ones. Gender differences were found for being alone and contemplating, stronger for men. Thinking that life is part of a greater whole was found mainly among on-campus students. Praying to Allah/God was most common among the youngest staff and students, as well as among women. Two segments of respondents were discovered-the Theists and Non-theists-where the former used more religious coping methods, were more likely to be women, older staff and students, on-campus students, married, have children, and lived in capital.Conclusions: Our conclusion is that the RCOPE methods, which include religious and spiritual meaning-making methods, are of great importance to the studied Iranian informants. However, they use some secular existential meaning-making coping strategies too. This is explained by the role of religion in the larger orientation system and frame of reference in parallel with a secular worldview. Further, a sharp distinction between religious and secular worldviews was not found, which is explained by the fact that secular norms are hardly internalized in ways of thinking in Iran.

- In this study, we map and describe the coping methods used by members of the university community in Sweden to deal with the first wave of the coronavirus pandemic. This study, which used simple random sampling, was quantitative. It employed a modified version of the RCOPE instrument as well as items from earlier studies of meaning-making coping in Sweden. Among participants (n = 277, 64% women), the most frequently used coping method was nature as a resource in dealing with stress and sadness, followed by listening to the sounds of surrounding nature and thinking of life as part of a greater whole; these coping methods were the most common in all subgroups studied. We used a cultural perspective to better understand the application of certain meaning-making coping methods.

Impact of Scattering Within a Multipath Simulator Antenna Array on the Ricean Fading Distribution Parameters in OTA Testing
- 2014

Tidskriftsartikel (refereegranskat)abstract
- In this paper, we investigate the unwanted scattering that exists within the multipath simulator (MPS) array antennas employed in over the air (OTA) testing of mobile terminals. The impact of scattering is evaluated in terms of the measurement uncertainty of the average received power and the Ricean K-factor. The maximum ratio combining diversity is investigated for a generic device under test comprising two half-wavelength dipole antennas. We provide closed-form expressions for the uncertainties of the average received power and the Ricean K-factor for a uniform circular array of MPS antennas and a 2-D uniformly distributed angle-of-arrival spectrum. We also derive the maximum number of MPS antennas and the minimum ring radius of the MPS system as a function of the separation between the most distant antenna elements if the device under test employs a uniform linear array. As a result, we provide design guidelines for MPS array in terms of the number antennas, the radius of the MPS array and the wavelength of the carrier frequency.

- This paper discusses the accuracy of different types of models. Statistical models are based on process data and/or observations from lab measurements. This class of models are called black box models. Physical models use physical relationships to describe a process. These are called white box models or first principle models. The third group is sometimes called grey box models, being a combination of black box and white box models. Here we discuss two examples of model types. One is a statistical model where an artificial neural network is used to predict NOx in the exhaust gases from a boiler at Mlarenergi AB in Vsters, Sweden. The second example is a grey box model of a continuous digester. The digester model includes mass balances, energy balances, chemical reactions and physical geometrical constraints to simulate the real digester. We also propose that a more sophisticated model is not required to increase the accuracy of the predicted measurements.

- The objective was to explore the relationship between the cortisol awakening response (CAR) and the metabolic syndrome (MetS) as defined by the National Cholesterol Education Program criteria. The final study sample consisted of 91 women (14 with MetS) and 84 men (15 with MetS), aged 45 to 70 years, from a general population sample. The only exclusion criteria were no consent, pregnancy, or insufficient cortisol testing. On the day of measurement (weekday), salivary cortisol was sampled at awakening and 15 minutes after awakening. Relative CAR (CAR%) and the MetS were the main variables studied. Results showed that, in women with the MetS, cortisol at awakening was significantly lower (mean, 8.92 vs 12.33 nmol/L; P = .05) and the CAR was significantly higher (91.4% vs 36.5%, P < .001) than in women without the syndrome. Significant difference in the relative CAR was also present between men and women with MetS (38.5% and 91.4%, respectively; P = .02). No difference was seen in the awakening response comparing men with and without the MetS. In a regression model, the response to awakening was dependent on the MetS in women (F1,89 = 13.19, P < .001); but the model was not significant in men. Furthermore, the awakening response was associated with more depressive symptoms in women (F1,80 = 8.12, P = .01) and with weekday/weekend cortisol sampling in men (F1,82 = 4.63, P = .03). The association between the relative CAR and the MetS remained significant but somewhat attenuated after adjusting for depressive symptoms (P = .01). Results indicate a sex difference in the CAR% in the presence of the MetS independent of depressive symptoms, a known correlate of the MetS.

Cohomology of arrangements and moduli spaces
- 2016

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis mainly concerns the cohomology of the moduli spaces ℳ3[2] and ℳ3,1[2] of genus 3 curves with level 2 structure without respectively with a marked point and some of their natural subspaces. A genus 3 curve which is not hyperelliptic can be realized as a plane quartic and the moduli spaces ?[2] and ?1[2] of plane quartics without respectively with a marked point are given special attention. The spaces considered come with a natural action of the symplectic group Sp(6,?2) and their cohomology groups thus become Sp(6,?2)-representations. All computations are therefore Sp(6,?2)-equivariant. We also study the mixed Hodge structures of these cohomology groups.The computations for ℳ3[2] are mainly via point counts over finite fields while the computations for ℳ3,1[2] primarily uses a description due to Looijenga in terms of arrangements associated to root systems. This leads us to the computation of the cohomology of complements of toric arrangements associated to root systems. These varieties come with an action of the corresponding Weyl group and the computations are equivariant with respect to this action.

Tidskriftsartikel (refereegranskat)abstract
- We develop an algorithm for computing the cohomology of complements of toric arrangements. In the case a finite group ΓΓ is acting on the arrangement, the algorithm determines the cohomology groups as representations of ΓΓ. As an important application, we determine the cohomology groups of the complements of the toric arrangements associated with root systems of exceptional type as representations of the corresponding Weyl groups.
