Namnval som social handling : Val av förnamn och samtal om förnamn bland föräldrar i Göteborg 2007–2009
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this doctoral thesis is to examine how parents in Sweden at the beginning of the twenty-first century use the process of naming as a resource to contribute to the creation of various identities for both themselves and their child. It is based on a two-component study — a postal survey and qualitative group interviews, both conducted in the city of Göteborg, Sweden — and includes parents with children born during 2007 and 2008. By combining different sources (names, surveys and interviews) and different methods (quantitative and qualitative), this study attempts to elucidate how first names and choices of first names can be given various social meanings. In contrast to previous socio-onomastic studies, this study considers not only whether naming contains any social variation, but also how and why such variation arises. The theoretical framework is a combination of onomastic, sociolinguistic, identity-theoretical and interactional theories. The results demonstrate that parents’ choice of first names for their children is an important social act. Through name choices and discussions of these choices, parents create what is known as social positioning, which in turn contributes to the creation of certain identities both for themselves and their child. A number of resources are identified which are used by parents to create different social positionings. This study also demonstrates how both macro-societal structures and interactional aspects influence this social positioning. Finally, this study argues that the observed social variation is best explained by the parents’ desire to identify with and contribute to the creation of different models for society, in which varying social values and attributes are important.

The Female Reader at the Round Table : Religion and Women in Three Contemporary Arthurian Texts
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Stretching back at least a thousand years, Arthurian literature constitutes a vigorous and varied genre that attracts scholarly attention. In a close reading of three modern Arthurian texts, Mary Stewart’s Merlin trilogy, The Crystal Cave (1970), The Hollow Hills (1973), The Last Enchantment (1979), Marion Bradley’s The Mists of Avalon (1982), and Stephen Lawhead’s Pendragon Cycle, Taliesin (1987), Merlin (1988), Arthur (1989), Pendragon (1994), and Grail (1997), this study focuses on the intersection between two of the genre’s motifs: religion and gender. Inspired by the medieval Arthurian tradition, which is exemplified in my discussion by Geoffrey of Monmouth’s Historia Regum Britanniae and Sir Thomas Malory’s Works, these three texts rewrite the medieval stories, not merely by changing the plots, but by expressing new political, social, and cultural views of the gendering of religion.Stewart’s, Bradley’s and Lawhead’s novels portray different religious traditions: respectively, an eclectic monotheism, Neo-Pagan Wicca, and Christianity. They also offer different gender perspectives: in Stewart, the ungendering of the narrator and the unobtrusive inclusion of women as independent actors; in Bradley, feminist and female religion; and in Lawhead, the rejection of women as independent actors in religion.Modelled on the feminist reader response theory developed by Patrocinio P. Schweickart, my reading centres on the female readers’ identification as moderated by her faith, and aims to demonstrate that the female reader’s response will inevitably be coloured by the objects of identification offered by the text, by their portrayal of women as religious actors, and by the feminisation of evil that is apparent in them. Besides privileging the female perspective, my reading also attempts to recognise and critique patriarchal portrayals of women. Ultimately, my study shows that the female reader’s identification or alienation proceed from the interaction of the her own experience with the texts’ portrayal of religion and gender.

Noise, eigenfrequencies and turbulence behavior of a 200 kW H-rotor vertical axis wind turbine
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Vertical-axis wind turbines (VAWTs) have with time been outrivaled by the today more common and economically feasible horizontal-axis wind turbines (HAWTs). However, VAWTs have several advantages which still make them interesting, for example, the VAWTs can have the drive train at ground level and it has been argued that they have lower noise emission. Other proposed advantages are suitability for both up-scaling and floating offshore platforms.The work within this thesis is made in collaboration between Halmstad University and Uppsala University. A 200-kW semi-guy-wired VAWT H-rotor, owned by Uppsala University but situated in Falkenberg close to Halmstad, has been the main subject of the research although most results can be generalized to suit a typical H-rotor.This thesis has three main topics regarding VAWTs: (1) how the wind energy extraction is influenced by turbulence, (2) aerodynamical noise generation and (3) eigenfrequencies of the semi-guy-wired tower.The influence from turbulence on the wind energy extraction is studied by evaluating logged operational data and examining how the power curve and the tip-speed ratio for maximum Cp is impacted by turbulence. The work has showed that the T1-turbine has a good ability to extract wind energy at turbulent conditions, indicating an advantage in energy extraction at turbulent sites for VAWTs compared to HAWTs.The noise characteristics are studied experimentally, and models of the two most likely aerodynamic noise mechanisms are applied. Here, inflow-turbulence noise is deemed as the prevailing noise source rather than turbulent-boundary-layer trailing-edge noise (TBL-TE) which is the most important noise mechanism for HAWTs. The overall noise emission has also been measured and proven low compared to similar sized HAWTs.The eigenfrequencies of a semi-guy-wired tower are also studied. Analytical expressions describing the first-mode eigenfrequency of both tower and guy wire has been derived and verified by experiments and simulations.

Valfrihetens geografi och rationella gymnasieval : En experimentell studie om elevers preferenser vid val av skola
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The increased possibility to choose school and adaption of market mechanisms has created a Swedish upper secondary school market that exhibits spatial variations. However, in the general political and medial debate on choices in the educational sector of today, geography has come to have a hidden place. Based on the rational choice theory, the reform proponents have taken for granted that students’ preferences reflect the quest for the best school of knowledge. Studying students’ preferences is thus central to be able to highlight the importance of the freedom-based reforms in the publicly founded sector.The aim of this thesis is to examine students’ preferences for attributes that are central to the choice of upper secondary school. A further purpose is, based on the preferences, to examine the reform-bearing rational choice theory. The empirical data is based on a feasibility study conducted on 587 students in Halmstad and on a larger national study with data from 1440 students. The national study is carried out on 16 different schools, divided into 12 different municipalities.The results of the thesis show that the students’ preferences are characterized by both academic and non-academic considerations. In other words, the students’ academic preferences have competition from other, non-academic preferences that also are of importance for the students and therefor affect how attractive a school is considered. Further, there are differences in preference between the students and it is mainly their grades that correlate with these differences. The study also shows that there are small differences between the students’ preferences that can be related to their spatial context. The fact that students’ preferences do not fulfill the expectations in the underlying and reform-bearing theory, raises the question of how the educational producers and the students use choices to design the school market. There is a fundamental positive value in being able to choose and people in general want to be free and self-determined. For both the individual and the knowledge society, it is, however, crucial that the freedom of choice is not used to deselect knowledge. In this context, understanding of students’ preferences is important.

Production and characterization of intraspecific somatic hybrids of potato (Solanum tuberosum L.)
- 1991
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A culture protocol has been developed for mesophyll protoplasts isolated from various d¡haploid clones of potato. A large number of call¡ was obtained after serial dilution of the cultures w¡th a suitable amount and type of medium at different stages of cell colony development.A polyelhylene glycol fusion procedure was developed that yielded up to 12 % heterokaryons. Using this fusion protocol hybrid cells have been manually lsolated, cultured and regenerated into plants. Fus¡on products were identified 2-3 days after fuslon by the dual fluorescence emission from the chloroplasts in mesophyll protoplasts (red) and the fluorescein diacetate stain in l¡ght and norflurazon bleached protoplasts (yellow-green). This fusion and select¡on strategy leads to the recovery of almost 100 % hybr¡d plants as established by isozyme analysls.Cytolog¡cal analysis of protoplast-derived plants and somatic hybrid plants revealed genetic changes as a consequence of protoplast culture and protoplast fus¡on. Twenty-three tetraplo¡d somatic hybrid plants were obta¡ned from 6 different calli and 9 of these were euploid.Morphological assessments of somatic hybr¡d plants of different ploidy levels demonstrated that tetraploid as well as several hexaploid somatic hybrids showed an increased vigour as compared to the parental plants. Most tetraploid somat¡c hybrids had a similar appearance although not all euploid plants were identical. Loss of vigour was evident in all mixoploid and octoplo¡d plants. These were stunted, weak and had an abnormal leaf morphology.The plastid type in hybrid plants was determined by RFLP analysis. All analysed hybrids had a cpDNA restrict¡on fragment pattern ¡dent¡cal to one of the parents wh¡ch contained either S. tuberosum or S. stoloniferum cpDNA. A slight preference for S. tuberosum plastids was observed in hybild plants. No influence on tho assortment of chloroplast by the norflurazon bleaching could be detected.
