Simulering som lärande inom prehospital akutsjukvård
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Den prehospitala akutsjukvården är ett komplext kunskapsfält som innebär att vårdaren skall kunna bemöta patient och närstående, bedöma skada, sjukdom och den aktuella situationen samt avgöra vilka vårdåtgärder som skall prioriteras.Patientens lidande kan lindras genom att vårdaren tränar färdigheter i ett prehospitalt kontext. Detta främjar en god och säker vård samt stärker patientens möjligheter till överlevnad.Resultatet visar på behovet av simulering inom prehospital akutsjukvård. Med simulering lär sig vårdaren att hantera realistiska, dynamiska och komplexa vårdsituationer, vilket skapar kunskaper, färdigheter och erfarenheter av omhändertagande av patient drabbad av högenergitrauma. Simuleringens utformning och miljö skapar förutsättningar för lärandet vilket framkommer i interventionsstudien.Utifrån resultatet i föreliggande forskning utvecklas en modell för lärande med hjälp av simulering.

The Wicked Problem of Privacy : Design Challenge for Crypto-based Solutions
- 2018
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Data privacy has been growing in importance in recent years, especially with the continuous increase of online activity. Researchers study, design, and develop solutions aimed at enhancing users’ data privacy. The wicked problem of data privacy is a continuous challenge that defies straightforward solutions. Since there are many factors involved in data privacy, such as technological, legal, and human aspects, we can only aim at mitigating rather than solving this wicked problem. Our aim was to focus on human aspects for designing usable crypto-based privacy-enhancing solutions. In this thesis, we followed a user centered design method by using empirical qualitative means for investigating user’s perceptions and opinions of our solutions. Most of our work has focused on redactable signatures in the cloud context within the eHealth use-case. Redactable signatures are a privacy enhancing scheme allowing to remove parts of a signed document by a specified party for achieving data minimization without invalidating the respective signature.We mainly used semi-structures interviews and focus groups in our investigations. Our results yielded key HCI considerations as well as guidelines of different means for supporting the design of future solutions.

Fears, Stress and Burnout in Parents of Children with Chronic Conditions : Treatment with Cognitive Behavioural Therapy and Mindfulness
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the present research was threefold: to investigate the fears of parents of children with chronic conditions; to evaluate the effectiveness of their treatment with either mindfulness-based therapy or cognitive behavioural therapy (CBT); and to assess treatment outcome in terms of health-related quality of life (HRQoL). Long-term stress can lead to some form of chronic stress reaction. In study one, fears of future cancer recurrence and of late effects of treatment were most prominent among parents of CNS tumour patients. Study two investigated the effectiveness of two group-based interventions on stress and burnout among parents of children with chronic conditions. Parents were offered either a CBT or a mindfulness programme. Both interventions significantly decreased stress and burnout. Study three focused on the HRQoL and life satisfaction of the parents in study two. The results indicate improvements for participants in both treatment groups regarding certain areas of HRQoL and life satisfaction. To conclude, fears concerning future cancer recurrence and late effects of treatment are most prominent among parents of children with cancer. Another conclusion is that CBT and mindfulness decrease stress and burnout and may have a positive effect on areas of HRQoL and life satisfaction.

Catch and effort from a recreational trolling fishery in a large lake
- 2016
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Over recent decades recreational fisheries have grown substantially throughout the world. Despite this increase, catches from recreational fisheries have often been ignored in fisheries management, although this is now being remedied. Monitoring recreational fisheries can be expensive, and the primary means used for monitoring is angler (creel) surveys, typically funded from sales of fishing licences. The studies presented in this thesis examine different approaches to monitoring recreational trolling fisheries’ catch and effort, where fishing licenses are not required and there are no reporting requirements. I present results from a complemented roving/mail-in survey undertaken during 2013-2014 to estimate recreational effort and catch of Atlantic salmon (Salmo salar) and brown trout (S. trutta) in the largest lake in the European Union, Lake Vänern, Sweden. I also evaluate different angler catch reporting methods (mail-in, tournament reports and face-to-face interviews) and compare catch rates within and among spring and fall fishing periods. In addition, mail-in survey data are examined for recall bias. I estimate that 28.7 tonnes of salmon and trout combined were harvested by the recreational trolling fishery in 2014, more than the commercial and subsistence fisheries combined. Seasonal differences in both recreational effort and catch were observed. Effort, in boat hours, was significantly higher in spring than in fall. Catch rates of trout were higher in fall than in spring, but there were no seasonal differences in catches of salmon. Harvest per boat day did not differ significantly among catch reporting methods, indicating that all three methods could be useful for managers interested in harvest rates. In contrast, total and released catch per boat day differed among reporting methods, with tournament anglers catching more fish in total. Finally, there was little evidence for recall bias in mail-in surveys, indicating that mail-in surveys are useful for collecting unbiased catch data. My study is the most comprehensive angler survey to date for Lake Vänern, and my results should be of immediate use to local fisheries managers and should also be of interest to researchers and managers interested in estimating catch and effort for fisheries at large spatial scales.

Förutsättningar för elevinflytande i grundsärskolan : Tillit, lyhördhet och vilja
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The curricula that defines special needs education in Swedish grammar schools states that students with intellectual disabilities should be given the possibility to participate in the planning and shaping of teaching and learning activities. The purpose of the study is to examine conditions regarding special needs students’ influence and how this influence is mediated. The focus of the study is subject based classroom situations. The method for collecting data has been observations. The empirical data consists of around 16 hours of video recordings, in addition to field notes. The observations took place in two special schools and all together 10 pupils, 5 teachers, and two student assistants participated. The theoretical framework is based on sociocultural theory with a specific focus on mediation. By using the theoretical terms object and subject positioning, the study also focuses on how teachers and students position themselves and each other. The results show that the students with intellectual disabilities are given opportunities for influence, but not very frequently. The most important mediating factors to promote influence are the teachers´ trust in the students´ abilities and skills, and the teacher’s keen responsiveness to the students’ expressed personal will. Influence is mediated both through the possibilities of participation that teachers offer, and the teachers’ affirmation of the students’ requests. Furthermore, the study shows that students are more likely to gain influence in one-to-one meetings with the teacher, where the focus is on the student’s individual interests and preferences. In order to provide increased levels of influence to all students with intellectual disabilities, teachers need to plan the education with focus on democratic processes.

Laborativt arbete i fysikundervisningen : Något som behöver diskuteras!
- 2015
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- BaksidestextI gymnasieskolans kursplaner för ämnet fysik framhålls det undersökande arbetssättet genom att betona att eleverna ska ges förutsättningar att utveckla förmågan att söka svar på frågor, planera, genomföra, tolka och redovisa experiment. Eleverna ska dessutom ges möjligheter att använda sina kunskaper i fysik för att kommunicera, argumentera och presentera slutsatser. Utgångspunkten i den här avhandlingen är att laborationsmomentet skapar en speciell diskurs där eleverna blir aktörer och läraren iträder rollen som observatör. I en sådan miljö skapas förutsättningar för att eleverna på ett naturligt sätt får möjlighet att prata och diskutera fysik, utifrån sina egna förutsättningar. Syftet med denna avhandling är att genom praktikbaserade studier tydliggöra hur fysiklaborationens utformning påverkar elevernas kommunikation och vidare hur eleverna använder språket vid laborationstillfället för att skapa förståelse. Detta bidrar till debatten om fysiklaborationens effektivitet, sett både ur ett undervisnings- och inlärningsperspektiv. Resultaten visar att olika laborationsformer är uppbyggda av liknande aktiviteter, men varierar i tid som ägnas åt de olika aktiviteterna. Aktiviteterna i sin tur skapar samtal av olika karaktär. Olika samtalsformer används för skilda syften. Ett analytiskt ramverk har skapats för att ingående kunna studera hur och vad eleverna talar om både på en lingvistisk och kognitiv nivå.

Learning Physics Through Communication During Laboratory Work : An empirical study at upper secondary school
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Laboratory work as a teaching and learning method is given prominence in the Swedish physics curriculum for upper secondary school. It is emphasised that students should be given opportunities to develop the ability to search for answers to questions, plan, conduct, interpret and present results. Moreover, students should also be encouraged to use their physics knowledge to communicate, argument and present conclusions. This thesis is based on the belief that physics laboratory work creates a special discourse, where the student becomes the actor and the teacher becomes the organiser and observer. Such an environment enables students to naturally engage in physics discussions using their own terms. The aim is to explore students’ laboratory work at upper secondary school in-depth, with respect to its design and influence on students’ communication. Through analysis of students’ communication, the purpose is to better understand the physics laboratory work’s possibilities as a teaching and learning method. This will contribute to ongoing debate about the effectiveness of laboratory work. The results show that laboratory work consists of similar activities but differs in amount of time allocated to the different activities. Different types of talk are used for different purposes. An analytical framework has been created to enable deeper investigations of how and what students are talking about at both a linguistic and cognitive level. Moreover, the analysis shows the importance of students acquiring knowledge about physics and understanding the value of using an investigative approach as well as acquiring core content physics knowledge.

Changing the servicescape : The influence of music, self-disclosure and eye gaze on service encounter experience and approach-avoidance behavior
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this thesis is to investigate and understand the effect of a servicescape’s ambient and social conditions on consumers’ service encounter experience and their approach/avoidance behavior in a retail context. In three papers, with a total sample of over 1600 participants (including 550 actual consumers) and seven experiments, the author investigates the effect of music (ambient stimuli), employees’ self-disclosure (verbal social stimuli) and employees’ gazing behavior (nonverbal social stimuli) on consumers’ service encounter experience and approach/avoidance behavior in a retail store.Paper I comprised two experiments, and the aim was to investigate the influence of music on emotions, approach/avoidance behavior. Paper II comprised two experiments, and the aim was to investigate the effect of frontline employees’ personal self-disclosure on consumers’ reciprocal behavior. Paper III comprised three experiments, and the aim was to investigate the influence of employee’s direct eye gaze/ averted eye gaze on consumer emotions, social impression of the frontline employee and encounter satisfaction in different purchase situations.The results in this thesis show that music affects consumers in both positive and negative ways (Paper I). Self-disclosure affects consumers negatively, in such a way that it decreases encounter satisfaction (Paper II) and, finally, eye gaze affects consumers by regulating both positively – and in some cases also negatively – consumers’ social impression of the frontline employee and their encounter satisfaction (Paper III).The conclusions of this thesis are that both ambient and social stimuli in a servicescape affect consumers’ internal responses, which in turn affect their behavior. Depending on the purchase situation, type of retail, and stimuli, the internal and behavioral responses are different.

Oral care quality in intensive care units and short-term care units : Nursing staff and older people's perspectives
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to investigate oral care and its quality through the perspectives of nursing staff in intensive care units and short-term care units and from the perspectives of older people in short-term care units. Methods: The mix-method study (I) had a concurrent embedded design and was cross-sectional. Eighty-eight intensive care nurses (response rate (RR) 40%) responded to the Nursing Care related to Oral Health questionnaire, and the data were analysed with analytic statistics and qualitative content analysis. The quantitative studies (II-IV), which were also cross-sectional, included 432 nursing staff in intensive care and short-term care (RR 51–52%) and 391 older people (RR 77%) in short-term care units. Participants responded to the modified version of the Quality from Patients’ Perspective instrument and provided information about person-related conditions. Descriptive and analytical statistics were used. Main results: Intensive care nurses perceived having the antecedents, knowledge, and skills to provide optimal oral care quality, but the result indicated that they were having difficulties putting these into practice (I). Areas for improvement in oral care quality were identified in both care environments (II). Older people preferred personalised information about oral health and oral care (III). Nursing staff as well as older people’s perceptions of oral care quality and its humanity aspects, seemed to be related to person-related conditions and differed between the two care environments. In short-term care, nursing staff’s preferences for the humanity aspects of oral care quality were higher compared to older people’s preferences (IV). Conclusion: Oral care is complicated and proactive and requires registered nurses’ and other nursing staff’s attention as well as educational and organisational initiatives. Many older people were assessed to have oral health problems. With early identification and optimal oral care, unnecessary suffering might be prevented. The identified quality improvement areas might guide RNs, nurse managers, and other nursing staff to further oral care quality development.

Lärares samtal om etik : Sociala representationer av etikundervisning på mellanstadiet inom ramen för de samhällsorienterande ämnena
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study draws attention to how teachers view and reason about ethics education in social studies. Based on the Social representation theory, the study aim to answer questions about the content and themes which are expressed in the teachers' conversations about ethics education. The study also wants to emphasize the communicative resources used by participants when they create a common understanding of ethics education.The study's empirical data consists of six focus groups interviews with teachers working with student in school year 4-6. Teachers in three teams (a total of 13 teachers) met at two occasions to talk about ethics education in social studies.The result from the analysis is presented in three parts. The first part draws attention to teachers' social representations of ethics education in social studies. Four social representations were found and they consist of teachers' ideas about content, methods and strategies, and the purpose and goals and difficulties in ethics education. The second part shows that the teachers express three social representations of how ethics education is related to, religious education, social studies and the school's overall mission. The analysis shows that ethics education is an important part of the religious education but also other subjects in social studies and the school's overall mission. The third part draws attention to the communicative resources that teachers use to create a common understanding of ethics education. Examples of communicative resources used in the conversations is teaching materials, national tests, the curriculum and their own teacher education.

Designing for Usable Privacy and Transparency in Digital Transactions
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- People engage with multiple online services and carry out a range of different digital transactions with these services. Registering an account, sharing content in social networks, or requesting products or services online are a few examples of such digital transactions. With every transaction, people take decisions and make disclosures of personal data. Despite the possible benefits of collecting data about a person or a group of people, massive collection and aggregation of personal data carries a series of privacy and security implications which can ultimately result in a threat to people's dignity, their finances, and many other aspects of their lives. For this reason, privacy and transparency enhancing technologies are being developed to help people protect their privacy and personal data online. However, some of these technologies are usually hard to understand, difficult to use, and get in the way of people's momentary goals.The objective of this thesis is to explore, and iteratively improve, the usability and user experience provided by novel privacy and transparency technologies. To this end, it compiles a series of case studies that address identified issues of usable privacy and transparency at four stages of a digital transaction, namely the information, agreement, fulfilment and after-sales stages. These studies contribute with a better understanding of the human-factors and design requirements that are necessary for creating user-friendly tools that can help people to protect their privacy and to control their personal information on the Internet.

Apply heat pump systems in commercial household products to reduce environmental impact : How to halve the electricity consumption for a household dishwasher
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In the household appliance industry, heat pump systems have been used for a long time in refrigerators and freezers to cool food, and the industry has driven the development of small, high-quality, low-price heat pump components. In the last few decades, heat pump systems have been introduced in other household appliances, with the express purpose of reducing electricity consumption. Heat pump tumble dryers have been on the market since 2000 and dominate the market today. A heat pump dishwasher was introduced on the market in 2014 and a heat pump washing machine in 2016. The purpose of adding a heat pump system in these three products was to decrease electricity consumption.Papers I and II used a methodology where transient simulation models were developed and used to increase knowledge about how to decrease electricity consumption for a tumble dryer and a dishwasher by adding a heat pump system. Papers II to V showed that a lower electricity consumption and lower global warming potential together with an energy-efficient drying method, where no humid air evacuates to the kitchen, give a heat pump dishwasher competitive advantages compared to any conventional dishwasher currently on the market. Using simulations, this dissertation concludes that a future commercial heat pump dishwasher, using R600a as a refrigerant, will reduce electricity consumption and total equivalent warming impact (TEWI) by 50% compared to the conventional dishwasher.The willingness from the customer chain to pay extra for this heat pump dishwasher is because of the decreases electricity consumption and the fact that no humid air evacuates to the kitchen. This willingness makes the heat pump dishwasher to a variant which have possibility to succeed on the future market.The challenge for the manufacturer is to develop and produce a high-quality heat pump dishwasher with low electricity consumption, predict future willingness to pay for it, and launch it on the market at the right moment with the right promotion in order to succeed.

Närheter och avstånd i ett nordvärmländskt skogslandskap : Praktiker och betydelser i nya tidsrumsliga sammanhang
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis examines the contemporary forest landscape of northern Värmland in Sweden in terms of practices, meanings and time-space relations. The increasing urbanization worldwide also affects the countryside landscape to produce what is generally referred to as “new ruralities”, which are the result of changed conditions for livelihood and leisure. What does the concept new ruralities mean in relation to the sparsely populated forest landscape of northern Värmland, Sweden?The thesis adopts a relational approach to landscape, which means that landscape entails and forms relations between the material, the immaterial, and the human. Landscapes stretches out in time and space, which means that they rests on and progresses from layers of earlier and contemporary activities. Landscape practices and meanings are therefore important for understanding changes as well as continuities in the context of new ruralities. Inspired by the Heideggerian basic assumption about dwelling the thesis methodologically draws on phenomenology, but also on ethnography to clarify the relation between the individual and the society. Interviews, field studies and participant observations with special focus on the settlement, community engagement, and forest and hunting were conducted in four parishes in northern Värmland.Proximity and distance turn out to be the common denominators in the meanings of the forest landscape that emerge from the study, but attention is also clearly drawn to the problems of depopulation, changing social relations, and the tension between the private and the common good. The new ruralities of the northern Värmland forest landscape seem to rest on the tension between flow and fixity, between change and continuity, as traditional practices are performed with new meanings and extended time-space relations.

Teaching and learning of chemical bonding models : Aspects of textbooks, students’ understanding and teachers’ professional knowledge
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Despite the growing importance of science and technology in society, school students consider these subjects irrelevant and hard to learn. Teachers must therefore know how to teach science in ways that enhance students’ understanding and interest. This thesis explores various aspects of the teaching and learning of chemical bonding, an important topic in school chemistry that is primarily taught using models. Research has shown that students find chemical bonding difficult to understand, and that the use of models in science education contributes to this difficulty. I therefore investigated teachers’ knowledge of how to teach chemical bonding and ways of developing it to improve students’ understanding. To this end, I analysed chemistry textbooks and teachers’ lesson plans, and conducted semi-structured interviews with teachers about their teaching of chemical bonding. This revealed that the representations of chemical bonding used in textbooks and by teachers can cause students difficulties. The teachers were generally unaware of how these representations might affect students’ understanding, implying that their pedagogical content knowledge (PCK) could be improved. To explore ways of incorporating research findings into teaching practice and developing teachers’ PCK, I conducted a learning study in which three secondary science teachers together explored and reflected on their own teaching practice. CoRe, a method for creating detailed descriptions of what, how, and why specific content is taught, was used to enhance the reflections and make the teachers’ PCK explicit. As a result, the teachers developed their representations of chemical bonding, became more aware of students’ understanding, and were better able to motivate their actions and choices of content and strategies.This thesis shows how professional development can bridge the gap between research and teaching practice, and how teachers’ PCK can be developed to improve students’ understanding.

Probing the effects of photodegradation of acceptor materials in polymer solar cells: bulk, surface, and molecular level
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Polymer solar cells (PSC) have reached record power conversion efficiencies of over 15%. The operational lifetime of PSCs, however, has to increase for their use in large area outdoor applications. In this work, a set of spectroscopic techniques (UV-vis, FTIR, NEXAFS, XPS) was used to study the impact of exposure to light and air (photo-oxidation) on the photoactive layer and its components. We focused on the electron acceptor components: the fullerene derivatives, PC60BM and PC70BM, and the polymer N2200. A comparative study of photo-oxidized PC60BM and PC70BM thin films by UV-vis and FTIR spectroscopy has shown that both materials undergo similar photochemical transformation, with the process being faster in PC60BM, due to the greater curvature of the C60 cage. Comparing experimental FTIR, XPS and NEXAFS spectra of the photo-oxidized PC60BM thin films with the calculated spectra for a large variety of photo-oxidation products, it was found that dicarbonyl and anhydride groups attach to the C60 cage during photo-oxidation. The study of photo-oxidized TQ1:PC70BM blend films by spectroscopic and J-V measurements shows that deterioration of the charge transport in PC70BM is the major contributor to the device performance degradation. Kelvin Probe measurements demonstrated that the charge transport deterioration was due to upward band bending and gap states being formed on the surface of photo-oxidized PC70BM. The TQ1:PC70BM blends films were further studied by AFM-IR in order to determine the lateral distribution of pristine components, as well as the photo-oxidation products. It was found that anhydride oxidation products of PC70BM are equally distributed over the blend film surface. The PC70BM is replaced with the polymer N2200 in the blend with TQ1. The photostability in air of the blend and its neat components was studied by UV-vis and FTIR spectroscopy. The spectra show that thermal annealing improves the photostability in air of both components.

Operationssjuksköterskans vårdande och kompetens inom perioperativ vård
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim was to describe and deepen the understanding of what operating theatre nurses experience as caring and responsibility as well as ethical problems in perioperative practice. The aim was also to investigate how operating theatre nurses perceive clinical competence in perioperative nursing.Methods: This research has a hermeneutic design. Qualitative, quantitative and mixed method was used. In the study (I), data were collected through interviews and analysed with phenomenographic method. In studies (II-III) the interview texts from the study (I) was reused. Secondary analysis were performed with hermeneutic text interpretation. In the study (IV), data were collected through a modified questionnaire PROFFSNurse SAS I, which was supplemented with an open question. These data were analysed using statistics and qualitative conventional content analysis.Results: Operating theatre nurses have the will to meet the patient, be involved and created continuity in the perioperative nursing process (I). Operating theatre nurses experience that they have a formal responsibility to ensure that patients are not at risk and maintain patient integrity and dignity based on personal ethical values (II). Ethical problems and value conflicts can occur if routines and habits prevent operating theatre nurses from caring and when their clinical competence are not utilized in perioperative practice (III). The operating theatre nurses’ self-assessment of clinical competence showed that academic degree, professional experience and interprofessional learning were important for the development of clinical competence. On the other hand, existing routines and habits, as well as inadequate resources, were an obstacle (IV).Conclusion: Perioperative nursing care includes a nursing process and the operating theatre nurses have responsibility based on ethical values. When the operating theatre nurses are prevented from being a caregiver or that their clinical competence is not utilized, stress of conscience can be caused. Important for the development of clinical competence is an academic degree, professional experience and interprofessional learning.

Språkintroduktion som mellanrum : Nyanlända gymnasieelevers erfarenheter av ett introduktionsprogram
- 2018
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Den här licentiatuppsatsen behandlar berättade erfarenheter av att vara elev på Språkintroduktion. Programmet är ett av fem introduktionsprogram i den svenska gymnasieskolan och tar emot nyanlända ungdomar i åldrarna 16 till 19 år. Utbildningen på Språkintroduktion har en tyngdpunkt på svenska språket samt andra ämnen som eleverna har behov av att studera. Sålunda ska undervisningen organiseras utifrån varje elevs förutsättningar och behov.Studien bygger på intervjuer med språkintroduktionselever. Analysen fokuserar följaktligen 22 elevers berättade erfarenheter av att vara elever på Språkintroduktion. Elevernas berättelser blir ett sätt att förstå hur deras erfarenheter av programmet flätas samman med tidigare skol- och arbetslivserfarenheter liksom med tankar om framtiden.I resultaten presenteras tre teman som framträder i berättelserna. Det första temat gäller samtliga elever och behandlar erfarenheten av att inte kunna svenska. Det andra temat innefattar vissa elever och synliggör två elevidentiteter som särskilt framträder. Den första av dem handlar om att gå från att vara en högpresterande elev till att vara nybörjare och den andra om att gå från att vara en elev med kort eller ingen skolbakgrund till att äntligen vara elev. Slutligen handlar det tredje temat om hur Språkintroduktion tar form som ett mellanrum.

A systemic stigmatization of fat people
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this work was to develop knowledge about and awareness of fatness stigmatization from a systemic perspective. The stigmatization of fat people was located as a social problem in a second-order reality in which human fatness is observed and responded to, in turn providing it with negative meaning. Four separate studies of processes involved in this systemic stigmatization were performed.In study I, the association between weight and psychological distress was investigated. When controlling for an age-gender variable, this association was almost erased, questioning the certainty by which a higher weight in general is approached as a medical issue. In study II, the focus was on stigma internalization where negative and positive responses combined were connected to fat individuals’ distress. We found that both responses seemed to have a larger impact on fat individuals, suggesting that the embodied stigma of being fat sensitizes them to responses in general. In study III, justifications of fatness stigmatization was explored by a content analysis of a reality TV weight-loss show. The analysis showed how explicit bullying of a fat partner could be justified by animating the thin Self as violated by the fat Other, thus downplaying the evils of the bullying act in favor of highlighting the ideological value of thinness.The implications of these studies were related and seated in a context comprising a historical aversion toward the fat body, a declared obesity epidemic, a new public health ideology, a documented failure to reverse this obesity epidemic, and a market of weight-loss stakeholders who thrive on keeping the negative meanings of being fat alive. The stigmatization of fat people was intelligible from a systemic perspective, where processes of structural ignorance, internalized self-discrimination, and applied prejudice reinforce each other to form a larger stigmatizing process. In paper IV, it was argued that viewing fatness stigmatization as oppression rather than misrecognition could hold transformative keys to social change.

Matematiska resonemang i en lärandemiljö med dynamiska matematikprogram
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall problem that formed the basis for this thesis is that students get limited opportunity to develop their mathematical reasoning ability while, at the same time, there are dynamic mathematics software available which can be used to foster this ability. The aim of this thesis is to contribute to knowledge in this area by focusing on task design in a dynamic software environment and by studying the reasoning that emerges when students work on tasks in such an environment. To analyze students’ mathematical reasoning, a new analytical tool was developed in the form of an expanded version of Toulmin’s model.Results from one of the studies in this thesis show that exploratory tasks in a dynamic software environment can promote mathematical reasoning in which claims are formulated, examined and refined in a cyclic process. However, this reasoning often displayed a lack of the more conceptual, analytic and explanatory reasoning normally associated with mathematics. This result was partly confirmed by another of the studies. Hence, one key question in the thesis has been how to design tasks that promote conceptual and explanatory reasoning. Two articles in the thesis deal with task design. One of them suggests a model for task design with a focus on exploration, explanation, and generalization. This model aims, first, to promote semantic proof production and then, after the proof has been constructed, to encourage further generalizations. The other article dealing with task design concerns the design of prediction tasks to foster student reasoning about exponential functions. The research process pinpointed key didactical variables that proved crucial in designing these tasks.
