Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Syftet med denna avhandling är att undersöka vilken ekonomisk och social ställning den judiska minoriteten intog i det svenska samhället under perioden 1870 till 1940. Tidigare forskning har riktat stor uppmärksamhet mot rättsliga och politiska aspekter av den svenska judenhetens historia, mer sällan mot judarna och samhället i en bredare bemärkelse. Andra studier har lyft fram antisemitism på svensk mark utan att koppla fenomenet till en social nivå.Genom en undersökning av hur judiska invandrare, med ursprung i Östeuropa, successivt fogades in i några svenska lokalsamhällen, tar denna avhandling ett bredare grepp på frågan om judarna och samhället. Här undersöks hur den svenska judenheten integrerades i samhället efter det att emancipationen gett judarna fulla medborgerliga och politiska rättigheter. Judarnas ekonomiska och sociala ställning undersöks, liksom den sociala antisemitism som drabbade judarna. Studien rör sig i gränslandet mellan social- och kulturhistoria. Undersökningen visar att merparten av judarna i Sundsvall, en betydelsefull handelsstad i norra Sverige, fick sin försörjning genom en föga lönsam gårdfarihandel under början av undersökningsperioden. Sedan butiks- och grosshandelsrörelser började grundas inleddes en långsam socioekonomisk klättring. I takt med de ekonomiska framgångarna ökade judarnas sociala status, med engagemang i föreningslivet och lokalpolitiken. De framgångsrika familjerna tonade ner sin judiska identitet till förmån för en borgerlig och nationell kultur.Ungefär hälften av den judiska gruppen fick aldrig uppleva framgången utan förblev en marginaliserad grupp, med småhantverk eller gårdfarihandel som försörjningsbas. Det stora flertalet av denna underklass saknade svenskt medborgarskap. En social klyfta vidgades gentemot den judiska borgerligheten. Under hela undersökningsperioden var antisemitismen en kulturell kod i majoritetssamhället, oavsett integration och socioekonomisk framgång. Mycket tyder på att det sociala klimatet blev mer fientligt gentemot judarna efter 1920. Studien visar att nationalstaten Sverige lämnade litet utrymme för multikulturella strukturer. Judarna accepterades som nationens styvbarn men knappast som fullvärdiga svenskar.

Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator
- 2015
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. The experimental setup, which was a small-scale, two-dimensional (2D), water-filled room model, was successfully designed and manufactured to be able to capture two-dimensional velocity vectors of the entire field using Particle Image Velocimetry (PIV). Using in-house software, it was possible to conclude that for an increase in pulsation frequency or alternatively in the flow rate, the stagnation zones were reduced in size, the distribution of vortices became more homogeneous over the considered domain, and the number of vortices in all scales had increased. Considering the occupied region, the stagnation zones were moved away in a favorable direction from a mixing point of view. In addition, statistical analysis unveiled that in the far-field occupied region of the room model, stronger eddies were developed that we could expect to give rise to improved mixing. As a fundamental experimental study performed in a 2D, small-scale room model with water as operating fluid, we can logically conclude that the positive effect of enhanced mixing through increasing the flow rate could equally be accomplished through applying a pulsating inflow.In addition, this thesis introduces and describes an experimental setup for study of air flow over a wall-mounted radiator in a mockup of a real room, which has been successfully designed and manufactured. In this experimental study, the airflow over an electric radiator without forced convection, a common room-heating technique, was measured and visualized using the 2D PIV technique. Surface blackening due to particle deposition calls for monitoring in detail the local climate over a heating radiator. One mechanism causing particle deposition is turbophoresis, which occurs when the flow is turbulent. Because turbulence plays a role in particle deposition, it is important to identify where the laminar flow over radiator becomes turbulent. The results from several visualization techniques and PIV measurements indicated that for a room with typical radiator heating, the flow over the radiator became agitated after a dimensionless length, 5.0–6.25, based on the radiator thickness.Surface properties are among the influencing factors in particle deposition; therefore, the geometrical properties of different finishing techniques were investigated experimentally using a structured light 3D scanner that revealed differences in roughness among different surface finishing techniques. To investigate the resistance to airflow along the surface and the turbulence generated by the surfaces, we recorded the boundary layer flow over the surfaces in a special flow rig, which revealed that the types of surface finishing methods differed very little in their resistance and therefore their influence on the deposition velocity is probably small.

Att bli, att vara och att ha varit : Om ingångar i och utgångar ur Jehovas vittnen
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation seeks to describe and investigate the entering and leaving of a highly structured and hierarchical religious community, exemplified in this case by the Jehovah's Witnesses. The respondents in this study were chosen from both active members of the Jehovah's Witnesses in Sweden and those who have left the organisation for personal reasons. Repeated interviews with ten active members of the organisation have been conducted in the course of the study and compared to equal numbers of former members. The interviews have been semi-structured to deal with questions of how a person has come into contact with the organisation; how they retrospectively experienced the process of entry; the reasons for becoming a member. Questions have also been asked about life in the organisation. The group of "exiters" have also been asked about the experience of leaving, why they wanted to leave, and how this process was started and carried out. In addition to this I have analysed a four-year diary describing the time inside and the process of leaving the organisation. This has given me an extra psychological insight into the inner experience of someone who has gone through the whole process. The analysis has been done by categorising the content of the transcribed interviews. The analysis of the diary has involved thorough reading, resulting in a division of it into four different parts, where each part has been given a certain key-word, signifying the author's emotional state when writing it. A person converting as an adult has to pass six phases before being considered a Jehovah's Witness by the organisation. These are: Contact with the Jehovah's Witnesses, studying the bible with members of the organisation, questioning, accepting, being active as publisher (spreading the belief), being baptised. For a person brought up in the organisation, the process to full membership is much shorter: Upbringing in the organisation, taking a stand on the belief, being baptised. The exit process contains of seven phases: Different levels of doubts, testing of doubts, turning points, different kinds of decisions, different steps in executing the decisions, floating, a period of emotional and cognitive consideration of membership and its experiences, relative neutrality.

Att säkerställa skriftspråklighet genom medveten arrangering : Wittingmetodens tillämpning i några olika lärandemiljöer
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The proposed Grounded Theory has been derived from how experienced teachers and their pupils, in four different teaching contexts, have used ’The Witting method’ to maximize literacy development among their pupils. The theory has been grounded through repeated comparisons and analysis of the empirical data. The specific aim of the thesis is to conceptualize and generate a theory about what four teachers and their pupils (n=40, over the period of the research), in different contexts, and over a number of years, actually do when working with The Witting method. A wider goal is to apply the implications of the derived grounded theory to general and special education theory in helping to alleviate reading and writing difficulties and prevent pupils from failing. The results show that the teachers have systematically strived to ensure each pupil’s reading and writing development and they do this through what is labeled ‘didactic arranging’. They also show an ability to adapt to situations, materials and spaces without losing their long-term aims. They are in charge of three competencies: ’me’, ’you’, and ’we’ - expressing this competence in documentation, by reflection and always in close collaboration with pupils and their families. The observed use of The Witting method would seem to enable a diagnostic mode of teaching as it contains tools that allow a teacher to follow each pupil’s reading and writing development. Teachers, pupils and the didactic procedures are shown to be in constant interaction. It was also found to be important that teachers believe that every pupil can learn. These teachers’ collective motto could be summed up as follows: never stop giving support and never stop assessing progress.

Demand-Supply Chain Management
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Purpose: This research aims to enhance the current understanding and knowledge of the demand-supply chain management (DSCM) concept by determining its elements, benefits, and requirements, as well as by analyzing key elements of the concept. Methodology: This research has utilized the case study strategy and the survey strategy, however, the case study strategy dominates. The case study research has involved five companies originating from Sweden and the collection of empirical data mainly from in-depth interviews with key persons representing senior and middle management. The survey research targeted the largest firms in Sweden and Finland and empirical data was collected through an online questionnaire. Findings: This research has established that the main elements of DSCM include market orientation, coordination of the demand and supply processes, viewing the demand and supply processes as being equally important, as well as value creation, differentiation, innovativeness, responsiveness, and cost-efficiency in the demand and supply processes. It has also been revealed that the main benefits of DSCM include enhanced competiveness, enhanced demand chain performance, as well as enhanced supply chain performance, while the main requirements of DSCM include organizational competences, company established principles, demand-supply chain collaboration, and information technology support. A key element of DSCM further investigated is differentiation focused supply chain design. It has been shown that these efforts can be organized into a process of five stages. In addition, it is important that this process is addressed in parallel with the new product development (NPD) process, that information is exchanged between them, and that they are directed on the basis of the same segmentation model. Another key element of DSCM further investigated is coordination between NPD and SCM. This research has identified several significant linkages between these management directions, which motivate the use of an integrative NPD process where the NPD functions are aligned with the main supply functions in the company and other sales-related functions supporting the commercialization. A final key element of DSCM further investigated is the significance of regarding the demand processes and the supply processes as being equally important. This research has revealed that logistics outsourcing can be risky, if it results in the supply processes being considered less important. Nevertheless, if senior management regards the outsourced processes as equally important as the in-house processes, the effect of logistics outsourcing on company strategies and direction in SCM could be reduced and logistics outsourcing could instead provide an opportunity to improve the design and differentiation of the supply chain. Research limitations/implications: This research has proposed, described, and further analyzed a demand-supply oriented management approach. Such a management approach stresses that the demand processes and the supply processes have to be coordinated and directed at an overlying level, in order to gain and sustain a competitive advantage in competitive and fragmented markets. This research is mainly explorative in nature, and more empirical data, from similar and other research settings, is needed to further validate the findings. Another limitation of the research is that it is essentially limited to Swedish companies (even if some Finnish companies are involved in the survey), however, many of the case companies have a large international presence and are among the top three in their industries, facts which provide some grounds for generalization. Practical implications: This research provides researchers and practitioners with insights into how to develop a demand-supply oriented business. It shows that companies should organize themselves around understanding how customer value is created and delivered, as well as how these processes and management directions can be coordinated. In order for this to occur, the demand and supply processes must be considered as being equally important and the firm needs to be managed jointly and in a coordinated manner by the demand- and supply-side of the company. It is also important that value creation is considered in both the demand and supply processes. Originality/value: Despite strong arguments from both researchers and practitioners for a demand-supply oriented management approach only a minority of companies appear to have effectively coordinated the demand and supply processes. This might be influenced by the lack of research examining how the demand and supply processes can be coordinated, what benefits can be gained by coordinating them, and what requirements are necessary to succeed. This research contributes by investigating these types of aspects further.

Individual information system acceptance behaviour : An electronic ordering system case
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Organizations have spent and continue to spend millions of dollars on information systems (IS) in order to enable business success. Information systems have long been used to help managers make better decisions, better understand the nature of customers and improve employee productivity. They have enabled transformations in organizations, such as simplification and acceleration of work processes, and contributed to continued improvement and innovation in these processes. It is not that easy however to make this simplification and acceleration of work processes to happen. A common problem is that individuals that are supposed to use these systems do not use them, and if an information systems is to contribute to business success it has to be adopted and used. The question is therefore, how do we get individuals to adopt and use systems that are implemented?This dissertation focus on what influences individual adoption and use, and how we can get individuals to adopt and use systems that are implemented. The information system under investigation is an electronic ordering (e-ordering) system. E-ordering systems are used by individual end-users (requestors, authorizers and goods receivers) in an organization when ordering products and services. The system aims at contributing to reduced maverick (i.e. wild= purchases and increased compliance with a few centrally chosen suppliers, thus facilitating lower purchasing prices and a reduction of the costs for purchasing. The thesis also discusses the relative difficulty in getting individuals to continue to use the systems compared to get them to adopt it. Another issue that is discussed is that the acceptance process does not have to happen gradually, it can instead happen in short spurts. It is further discussed what can influence these spurts.

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.

Digital technologies in preschool education : The interplay between interactive whiteboards and teachers' teaching practices
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is aimed at exploring the ways in which a digital technology, the interactive whiteboard (IWB), interplays with preschool teachers’ teaching practices. In the literature and ongoing debates there are different claims about if and how digital technologies can contribute to children’s development and solving preschool educational challenges. The ways children learn from and by digital technologies have been widely studied, however, there is relatively little research on how digital technologies interplay with teachers’ teaching. Correspondingly, the approach taken here to the ways in which digital technologies contribute to early childhood education is based on preschool teachers’ practices and reasonings.In particular the focus is placed on the following research questions. How do preschool teachers reason about the embedding of IWB into their teaching practices? How do preschool teachers use IWB to structure their teaching practices? How do preschool teachers scaffold children’s learning processes in a context where IWB is used? How do IWBs mediate teaching actions? and What is privileged in the IWB-mediated teaching actions?To address these research questions, three sets of empirical data have been collected. These datasets, including interviews with preschool teachers and video observations of their teaching using IWB, were collected in 2012-2013 within the frame of the licentiate thesis and in late 2017 and early 2018 within the framework of the PhD thesis. Analytically, the study is built on a sociocultural perspective that assumes that learning is a constant social process.The findings of this study provide empirical knowledge regarding how preschool teachers reason about their use of IWB in teaching. The findings of the study, further, show that preschool teachers use diverse strategies to structure their teaching practice using the opportunities that IWB offers. The teachers’ use of IWBs exemplifies the ways they take into account the available technological features to support children’s learning within their ZPD.In its identification of scaffolding actions, this study provides rich details about how preschool teachers use a particular digital technology, IWB, in their teaching to support children’s learning and development. Scaffolding is seen as a collaborative process where preschool teachers’ active participation and emotional support plays an important role in fulfilling the given practices, and leads children’s learning to a higher level. By exploring how teachers’ teaching actions are meditated by the mediational aspects of IWB and what is privileged in the IWB-mediated teaching actions, the current study, moreover, contributes to mapping the desirable or undesirable consequences of using digital technologies in early childhood education. It also exemplifies how the use of IWB interplays with preschoolt eachers’ teaching practices.The new dimensions to scaffolding theory constructed in this thesis, further, contribute to expanding of Wood et al. (1976) theory. This can have significance for other studies using digital technologies in educational settings and can contribute to early childhood education, since early interventions, such as the ways preschool teachers support children, are particularly crucial for a child’s learning and their development later on in life.

Design för lärande : barns meningsskapande i naturvetenskap
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the study was to describe and analyse the design of learning environments and how children in preschool, preschool class and primary school create meaning and learn from the teaching aids offered to them in scientific activities planned by teachers.The theoretical reference frame was obtained from multimodal and design-oriented theory, with its focus on the creative dimensions of learning and detailed aspects of how learning takes place. The study is based on video-observations and constituted an in-depth study of a limited number of occasions spent in preschool, preschool classes and the first year of primary school when science lessons were in progress. Four children’s groups, thirty-six children and five teachers took part in the study, from different schools and municipalities. The children are aged between three and seven. The video-observations have been transcribed as text and analysed with analytical concepts found within the theoretical framework.The results show that considering the number of children in the children’s groups, relatively few children take part in the scientific learning contexts. Changes in the balance of power were evident in the learning settings and followed the interaction patterns that were identified in the children’s groups. The results also show that children create representations – both individually and corporately – in new or different ways that are made up of analogies expressed in terms of equivalent, existential, expressive and figurative analogies. The children’s verbal expressions that corresponded with the responses expected by the teachers were highly valued, were paid attention to and were recognised as know-how. This meant that many of the potential meanings that exist in children’s meaning-making in science become invisible. The results have educational implications for teachers’ work at the local level and for teacher training.

Glaspärlespelaren : Nya världar, etik och androcentrism i Peter Nilsons science fiction-romaner
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on Peter Nilson’s (1937-1998) science fiction texts, and particularly on how narrative themes and structures in these texts are related to science as well as to the literary tradition of science fiction (SF). The primary texts are the novels Arken (The Ark, 1982), Äventyret (The Adventure, 1989), Rymdväktaren (The Space Guard, 1995), Nyaga (1996) as well as the short story “Kvinnan som ville ha barn med döden” (The Woman Who Wanted a Child With Death, 1987). Nilson was an established astronomer before publishing fiction, and in both novels and essays he joins “the two worlds” of the natural sciences and the humanities. My study of the reception of his work shows that his symbolic capital, his authority as a scientist, was transferred from one field of knowledge to another, thus increasing the value of his SF texts in critics’ eyes. Central to my analyses are the authorial strategies Nilson used when building bridges between natural science and the humanities, in a move evoking the Glass Bead Players in Herman Hesse’s novel The Glass Bead Game. My study shows that, unlike Hesse’s protagonists, the Glass Bead Players in Nilson’s texts accept, or even welcome, extreme consequences of scientific developments, such as the extinction of life as we know it.SF texts are traditionally categorized as either dystopic or utopic depending on the level of pessimism or optimism in their depictions of technology. I suggest instead that dystopic or utopic outcomes in modern SF novels depend on whether the texts build on an aleatoric or a teleological worldview. In aleatoric narratives, humankind is depicted as alone in the universe and thereby responsible for its own destiny. Teleological narratives feature superior, god-like forces from other worlds, which interfere with life on Earth and may elevate humans to higher levels of consciousness. The latter perspective, which is favoured in Nilson’s SF texts, entails that responsibility is removed from humankind since what happens is presented as meant to be. The tropes of the void and of creatio ex nihilo are recurrent in the examined texts, for instance through the use of myths and archetypes containing images of emptiness such as the “creation out of nothing”. Further, Nilson’s characters are often situated in a mental or physical “void” where their knowledge is of no use to them. My readings show that these voids are not empty but contain mythical and archetypal elements which activate obsolete religious ideas and gender models, such as the Logos vision: the creative power of words. This conservative tendency seems all the more surprising and problematic considering that the SF-genre is based on explorations of possible new worlds and beings.
