    Exploring language skills and well-being in inclusive preschools: The impact of a dialogic reading intervention2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Language skills during the preschool years are important for cognitive and social development, learning, and well-being, especially for children that are less proficient in the language that peers and teachers use for communication and teaching, known as the majority language. The overall aim of this thesis is to explore the effect of a practice-embedded introduction of dialogic reading in preschool, a method that engages children in conversation, using language-promoting strategies. Teachers performed dialogic reading for 85 five-year-old children in preschools. Children's linguistic progress was observed, while also recording their self-reported state of well-being. Based on the theme of language and well-being in early education, three studies were conducted. 

    In Study I, a British well-being measure for young students, “How I Feel About My School (HIFAMS),” was translated, validated, and assessed for psychometric properties. In total, N = 228 children self-reported their well-being in early education. Study I included a combined sample of school-aged children (n = 143) and a preschool sample (n = 85), where the latter also participated in Study II and Study III. Study I confirmed a one-factor structure of HIFMAS in a confirmatory factor analysis with good model fit. The results showed that the HIFAMS can be used in Sweden to measure child well-being in preschool and early school years.

    In Study II, structural equation modeling was used to examine the relationship between language skills and self-reported well-being among preschoolers (N = 85). The assessment of language skills comprised both narrative and vocabulary abilities, while well-being was measured by HIFAMS. Language background (home language exposure) and gender were examined in relation to language abilities and well-being. Study II discovered no association between language skills and well-being. Children with a non-Swedish language use at home (additional language learners) displayed similar narrative skills but had less vocabulary. The results of Study II align with previous research, highlighting the significance of extensive language exposure for children whose home language differs from the language encountered in preschool.

    In Study III, language development and child well-being were analyzed after a dialogic reading intervention. Ten preschool teachers delivered the intervention in small groups (four to eight children). The teachers performed the dialogic reading during two periods, and the children at each preschool were randomized to attend direct (group A) or delayed intervention (group B). The outcome measures were the same as in Study II and assessed pre-, mid-, and post-intervention. Study III showed that children improved their language skills after engaging in a dialogic reading intervention, with improvements regardless of language background. The well-being remained steady during the course of the trial. 

    Taken together, the results of these three studies indicate that language development in terms of vocabulary can be promoted by dialogic reading, and children that are additional language learners show a similar progression as their peers. Furthermore, these studies show that self-reported well-being can be measured in the early education context and that children’s self-perceived well-being in preschool was not associated with early language skills. The implications of these studies and the significance of the results for educational practice are addressed.

    Sustainability-Linked Bonds: A study comparing the yields of sustainability-linked bonds and green bonds. 2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper analyzes the difference in yield to maturity between two types of ESG-fixed income instruments, and aims to answer the research question "Is there a yield difference between sustainable-linked bonds and green bonds issued in Europe?". The sample consists of a total of 1499 bonds, issued between the time period 2019-2023, where the databases Bloomberg and Refinitive Eikon have been used to collect and filter the data. The null hypothesis is that there is no significant difference between the two bond types, the alternative hypothesis states that one of them has a premium towards the other. For the methodology, the sustainability-linked bonds (SLBs) are matched with green bonds, creating pairs based on similar characteristics. This procedure, which corresponds to previous work by Kölbel & Lambillon (2022), alongside an OLS regression, are used to answer the research question. The results show that there is no significant yield difference between the bond types. This conclusion is drawn from using a Wilcoxon test on the paired bond sample. The result from the regression implies that the yield on green bonds is explained by the defined independent variables to a greater extent than the yield on SLBs.

    There are amble number of prior studies which have found a present premium on the ESG instruments green bonds (Fatica et al., 2019; Baker et al., 2018; MacAskill et al. 2021; Kapraun, 2021; Löffler et al., 2021; and Zerbib, 2018) and SLBs (Kölbel & Lambillon, 2022; Feldhütter et al., 2023). This essay aspires to use previous research findings as reference for comparing bond types against each other rather than their performance against conventional bonds. Additionally, the SLB instrument is still considered relatively novel and hence this essay aims to contribute to existing knowledge with new inputs and findings.

    The Nordic welfare city – types and dimensions2024In: Nordic Welfare Cities: Negotiating Urban Citizenship since 1850 / [ed] Magnus Linnarsson & Mats Hallenberg, New York: Routledge, 2024, p. 209-221Chapter in book (Refereed)
    Abstract [en]

    An important conclusion of this book is that the evolution of the Nordic welfare city was a process of several overlapping phases or dimensions. This chapter suggest that this development should be interpreted as a succession of different types of welfare cities with specific characteristics; the patriarchal, the economic, the social, the universal, and the neoliberal welfare city. The model covers the whole period from c. 1850 to the present, addressing municipal organization as well as political regimes. We also contend that it was not material infrastructure by itself, but rather the ongoing contestation and negotiation over a plethora of various welfare services that eventually contributed to a widening and strengthening of urban citizenship. The types of welfare cities suggested thus represent different outcomes from the ongoing struggle over material and cultural networks, involving paupers as well as politicians and professional experts.

    The Nordic welfare city: Urban community and public services since 18502024In: Nordic Welfare Cities: Negotiating Urban Citizenship since 1850 / [ed] Magnus Linnarsson & Mats Hallenberg, New York: Routledge, 2024, p. 1-16Chapter in book (Refereed)
    Abstract [en]

    This introductory chapter argues for the use of the concept of ‘welfare city’ to understand and explain the development of modern public services and welfare systems. Previous research has hitherto put too much emphasis on the welfare state and on the period after 1945. This book calls for a shift in perspective, from the national level, to the local level, as well as a focus on the decisive period 1850–1940. Urban areas and cites were of paramount importance for the establishment of public services and welfare systems. The analytical framework deployed in this book, therefore, places urban politics in front of national politics and shifts the chronological focus to an earlier period in time. This theme and its adjacent argument are explored through studies of the Nordic countries. The chapters contain various examples on welfare and public services that includes infrastructure and housing projects, but also health care, education, outdoor life and entertainment. Together, the contributing authors claims that it is necessary to analyse local politics in order to explain the discursive changes that paved the way for a wave of investments in public services and social welfare in the period.

    IKT-plattform för att stödja entreprenörskap diasporan – Fallstudie av den senegalesiska diasporan i Italien2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    There are millions of people living outside their countries of origin and every year the number

    increases. These migrants have potentials in developing their own country of origin by

    supporting co-development through financial, social and commercial activities. Information

    and communication technologies (ICTs) can be used to facilitate the diasporas’ activities to

    accelerate the co-development. In the past few decades, there has been an increase interest on

    this topic among the scholars. DiasporaLink is one such project, that investigates, evaluates and

    facilitates transnational diaspora entrepreneurship (TDE). This research paper was conducted

    in connection with DiasporaLink’s work package 7: ICT as a facilitator of TDE. This thesis

    addresses differences in countries and societies based on the accessibility of ICT resources and

    the context of cooperative activities. Accordingly, researchers examine the ICT tools and

    activities used in the context of the Senegalese diaspora living in Italy and see how these tools

    can be organized as an intra-corridor platform to further facilitate and promote the TDE. The

    study follows Strauss & Corbin's grounded theory approach. Data was collected from

    Senegalese diasporas in Italy, using semi-structured, in-depth individual interviews with a

    theoretical sampling method. The findings concluded that the most appropriate front-end tools

    for the intra-corridor platform between Senegal and Italy are WhatsApp, Facebook and SMS

    with voice command and with the use of French, Italian and Wolof languages. The findings

    also revealed that the back-end technology could be facilitated by software such as Joomla.

    However, the responsibility of financial services should be taken by an institute with a secured

    proprietary system, such as a bank or a money transfer service company.

    Abstract [en]

    Today, despite monumental walls and solid construction, the deserted graveyard in Kinne-Kleva seems to fade away as an old Christian memory. However, if you just stop for a moment and take a closer look, rethink, and challenge your thought. You might realize that the place may have served another function than Christianity. by studying 99 burial sites in Västergötland, 9 categories such as wall constructions and cult has been revealed. With an analysis, refining categories through new research and adding them toghether, the monumental construction suddenly seems to might have had another function in the Iron Age.

    Runpelaren i Breza och dess runinskrift: En studie av Brezapelaren, futharkinskriptioner och identitet i folkvandringstidens (4-600 tal) Europa2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper aims to contribute to the broader understanding of the Brezapillar, a 6th century rune-find from Bosnia and Herzegovina, and the runic script in migrations-era Europe. This, through an analysis of the Brezapillar, the futhark-inscription on it and its find-site, a comporation of the Brezapillar with other European rune-finds from the same period, and a theoretical framework based in theories about identity, language and human reaction to social climate. This paper includes literature in more languages than has previously been used in research on the Brezapillar, aiming to bridge previous misunderstandings about it. The conclusions concern immaterial similarities between European migration-era rune-finds and the Brezapillar, dating and categorization of the inscription on the Brezapillae, the significance of the futhark as an inscription, and who carved the runes on the Brezapillar, as well as why.

    Abstract [en]

    The Viking age of Gotland has been subject to extensive studies. Research often addresses treasures, highly monetary valued objects, and changes in religion. In contrast, research on natural objects as fossils have received little attention. This bachelor’s thesis seeks to understand the usage of fossils in the Viking age of Gotland. With quantitative and qualitative analysis of fossils, this material shows us that people made elaborate choices in every step of utilization and with high probably created meaning through them. This study demonstrates that fossils are a heterogeneous archaeological material with capability to show us complementary view of the people who used them.

    Abstract [en]

    This essay aims to understand and analyse earlier research concerning women’s roles in the Late Iron Age through a gender perspective. This will be done by analysing the Volva theory in relation to ancient medicine in Scandinavia with the primary focus on the medicinal herb henbane. The volva theory and the interpretation of grave 4 at the fortification of Fyrkat as a “Volva grave” had an immense impact on contemporary scientific research and popular science. The essay will examine the volva grave, at Fyrkat in Jylland, Denmark because it’s unique finding of henbane seeds. For comparison the essay will look at other archeological contexts containing henbane. The Oseberg grave will also be included in this essay because of its relevance for the volva interpretation and gender discourse in earlier research.

    An Investigation of Support for Productive Skills in textbooks: A mixed method study of grade 8 materials2024Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    English language learning materials take a central role in Swedish secondary schools. The curriculum in Sweden advocates for communicative language teaching where students are expected to produce language in various contexts without restriction. There is much prior research on different textbooks used in Sweden. However, there has been limited analysis of how well a textbook aligns with the curriculum in terms of compliance with CLT expectations particularly for productive skills. As CLT preaches free production, it is important for teachers to know which books to choose for their courses to successfully incorporate the material to improve their students’ productive skills in various contexts. This study analysed Focus on English 8 which consists of a textbook and a workbook to shed some light on to what degree this textbook follows the Swedish curriculum with a focus on CLT aspects. This was done by using a mixed methods content analysis by conducting both a quantitative and qualitative analysis. The quantitative analysis was done by counting the amount of controlled to uncontrolled exercises in the textbook and workbook. In contrast, the qualitative analysis focused on the scaffolding present in the production exercises. Results show that while the book adheres to the curriculum, the textbook and workbook by themselves do not sufficiently facilitate free production. Thus, several steps outside the teaching materials need to be taken to encourage students to freely produce the language.

    A Utopia for Our Times: from Callenbach’s Ecotopia to Robinson’s Ministry for the Future2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this paper, I explore the emerging genre of Ecotopian fiction, which envisions alternative societal structures through an environmental or ecological lens. Examining two seminal works, Kim Stanley Robinson's Ministry for the Future (2020) and Ernest Callenbach's Ecotopia (1975), I investigate how these ecotopian narratives contribute to progressive ideologies on resource management, shedding light on the environmental requirements of utopia. Applying Darko Suvin's methodology to analyse the utopian framework in both novels, my reading of the works demonstrates that Callenbach's Ecotopia offers a confined utopian vision while Ministry for the Future employs a narrative approach that encompasses multiple possible utopian horizons. This adaptation of the Ecotopian framework serves to reimagine and reassess our strategies for addressing climate challenges within the complexities of the global economy. My argument draws from Booker and Daraiseh reading of Ministry for the Future which posits that the dialogic elements within Robinson's work foster reader engagement, prompting consideration of diverse perspectives and possibilities. Moreover, the polyphony of narrators in the Ministry for the Future facilitates a detachment of climate resolutions from Western-centric perspectives and from the perspective of one person - an imperative step towards the necessary global system change. As agents shaping potential worlds, ecotopian writers must articulate new economic systems in a manner that resonates with readers, fostering integration of these concepts into the collective consciousness. I contend that, to endure impending challenges, it is essential to continue developing the ecotopian horizon, exploring variations on ecological economies and that is best done through a multi-voiced approach. This ongoing effort is crucial to ensure the survival of future generations, empowering them to contribute to their own narratives of ecotopia.

    The Impact of Gamification on Vocabulary Acquisition: A Comparative Study of Two Student Response Systems in Enhancing Vocabulary Acquisition2024Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As digitalization continues to advance, digital tools have become omnipresent in the classroom, and Student Response Systems (SRSs) have emerged as a valuable tool for teachers. However, the added value and efficacy of integrating gamified SRSs, compared to non-gamified SRSs, in the classroom has yet to be fully explored. Furthermore, little attention has been paid to non-gamified SRSs. The present study examines how a gamified learning environment in SRSs impacts vocabulary acquisition compared to a non-gamified learning environment. To analyze this effect, a quantitative study was designed using statistical analyses such as the Shapiro-Wilk test, the Friedman test and the Wilcoxon signed-rank test. SRSs, namely Gimkit and Socrative, were selected to measure vocabulary acquisition.

    A total of 61 high school students studying English were enrolled in this study. Eighteen target words have been picked from two different vocabulary books designed to help students reach the C1 level in English. The selected words have all been identified as adjectives. The students were split into two class-based groups, and each was assigned a SRS to use for two 20-minute study sessions, happening at an interval of three days. To measure the effect of the two SRSs on vocabulary acquisition, three tests were conducted over three weeks. The students took a pre-test, an immediate post-test after the second study session, and a final delayed post-test two weeks later.

    The statistical analysis and the results of the three tests measuring vocabulary acquisition revealed a statistically significant improvement in vocabulary test scores for both groups in the short- and long-term. However, no statistical significance was shown for the test scores between the two groups: gamified and non-gamified learning environments. Hence, a gamified learning environment using SRSs was shown to have no statistical significance on vocabulary learning and retention compared to a non-gamified one. While digital tools are widely embraced, this study suggests that gamified SRSs, compared to non-gamified SRSs, may not offer a significant advantage in terms of vocabulary acquisition and retention. It is, therefore, important for the teachers to get to know their students and find the type of SRSs that suit their learning style best. Further studies could investigate the impact of gamified and non-gamified SRS on the students’ vocabulary acquisition and motivation over a school year to understand the effects better.

    Love, Trauma and Emotional Abuse in Charlotte Brontë’s Jane Eyre2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Despite various studies regarding love in Charlotte Brontë’s novel Jane Eyre, little is known about true affection. Early research indicates that Jane’s romantic feelings for Rochester are a result of patriarchy and childhood trauma. However, these scholars have been influenced by an older view of affection that indicates that in love, cruelty and destructiveness cannot exist.  

    This study builds on previous research; however, it adds a new philosophical aspect to demonstrate that it is ontological rootedness that defines love rather than benevolence and altruism. The primary source for this study is Charlotte Brontë’s novel Jane Eyre. Psychological theories have been incorporated to illustrate that Jane has endured childhood trauma which results in her being vulnerable to Rochester’s emotional abuse. However, the analysis also integrates a philosophical aspect of what love is that demonstrates that despite Jane’s childhood trauma and Rochester’s manipulation, Jane still has genuine affection for Rochester. In other words, this study shows that Rochester is emotionally abusive towards Jane but that love in the novel is not defined by kindness and selflessness. Thus, it is true love that Jane feels for Rochester. 

    Keywords: Charlotte Brontë, Jane Eyre, psychology, childhood trauma, emotional abuse, manipulation, love, Simon May, philosophy.

    Development of large-scale molecular and nanomaterial models2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Molecular simulations can access unique atomic-scale information about new materials, pharmaceuticals, and biological environments, making cost-effective predictions and aiding experimental studies. They are particularly useful for describing the mechanisms of nanoscale phenomena and the biological/inorganic interfaces. However, the computational cost of molecular simulations increases with the size of the system as well as with the model complexity, which is related to the accuracy of the simulation. This thesis aims to develop efficient large-scale molecular models that capture important structural details of the atomistic simulations. In particular, we focus on the TiO2-lipid interface, which forms in the living cells, exposed to TiO2 nanomaterials, but is also relevant in the context of biomedical applications. We have studied the interface using atomistic molecular dynamics simulations and found that the characteristics of the lipid adsorption depend on the type of the TiO2 surface, lipid headgroup composition, and the presence of cholesterol. We then derive a coarse-grained molecular model of the TiO2-lipid interface to enable the large-scale simulations of TiO2 nanoparticles interacting with model cell membranes. We show that the strength of the lipid adsorption increases with the size of the nanoparticle and that a small TiO2 nanoparticle can become partially wrapped by a lipid membrane. To improve the transferability of the coarse-grained model, we design and test an artificial neural network that learns the interactions in coarse-grained water-methanol solutions from the structural data obtained in multiple reference simulations at atomistic resolution. We show that in the studied system, the neural network learns the many-body interactions and accurately reproduces the structural properties of the solution at different concentrations.

    Arthropods in Constructed Wetlands: Ecosystem Processes and Riparian Biodiversity2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Constructed wetlands in the agricultural landscape are known to harbor immense arthropod biodiversity, however, riparian arthropod communities have often been neglected compared to aquatic communities when studying environmental responses. These wetlands are highly productive, but vary in form and composition based on its purpose, which influences the communities that inhabit them. Both biotic and abiotic wetland characteristics are known to drive aquatic arthropod community compositions, whereas knowledge is currently lacking as to the influence from characteristic wetland properties on riparian arthropods.

    This thesis aimed to shed a light on characteristic wetland drivers on riparian arthropod populations and communities. We explored how chironomid emergence rates and diversities responded to wetland nutrient loads and primary production (Chapter I), and subsequently if trophic cascading relationships could be observed across the aquatic-terrestrial boundary to riparian predator abundances (Chapter II). We also explored how riparian arthropod community compositions responded to wetland hydrologic dynamism, shoreline inclines and vegetation height, and grazing management (Chapter III), and finally how characteristic wetland shoreline properties influenced riparian arthropod diversities and habitat specializations (Chapter IV).

    In Chapter I we found that emergence rates and diversities of chironomids increased with aquatic chlorophyll concentrations during parts of the season but decreased during others, and that chironomid taxonomic diversity correlated with the aquatic concentration of methane. These findings support previously suggested trade-offs relationship between emerging chironomids and methane. We expanded on these findings in Chapter II, where we found that both primary-and secondary consumer abundances responded to wetland nutrient loads and chlorophyll concentrations, but that this trophic pathway was more complex than from primary producers, through primary consumers to secondary consumers. In Chapter III we found that some riparian arthropods responded to hydrological dynamism, but that surprisingly many groups were unaffected. We also found that many groups responded to shoreline vegetation height, but that responses were group specific. Similarly, in Chapter IV we found that shoreline properties greatly influenced spider, beetle and predatory Diptera diversities in constructed wetlands, and that their habitat specialized species richness varied greatly between groups.  

    Altogether, these findings illustrate the complexity of wetland arthropod ecology, and the need for attention to these previously understudied systems. It also highlights the importance of comprehension regarding constructed biodiversity wetlands if the aim is to improve biodiversity across multiple taxa.

    Paleoclimate and seasonality on Sumatra during the Late Glacial and Holocene: Insights from biomarkers and climate model simulations2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Deep atmospheric convection in the Indo-Pacific Warm Pool (IPWP) is a key driver of the Hadley and Walker Circulations that modulate the Asian-Australian monsoons and the El Niño Southern Oscillation (ENSO). Temperature and rainfall seasonality, i.e., the amount and timing of precipitation, impacts ecosystems, carbon content in soils and peats, and human livelihoods. Yet, past climate variability in the IPWP is poorly constrained. The Maritime Continent, located in the center of the IPWP remains a “quantification desert”, with a scarcity of terrestrial paleoenvironmental reconstructions.

    This thesis investigates the evolution of temperature, precipitation amount and seasonality over the Late Glacial (14.7-11.7 ka BP) and the Holocene (last 11.7 ka). This is achieved by combining climate model simulations and lipid biomarker analyses of terrestrial peat archives from Sumatra. Temperature and seasonality were explored by analysis of climate model simulations for the Late Glacial and Holocene. Microbial membrane-derived glycerol dialkyl glycerol tetraethers (GDGTs) were investigated as temperature and hydro-environmental proxies. Using n-alkane distributions, the abundance of algae, aquatic and terrestrial plants was reconstructed and linked to past hydroclimate variability. The hydrogen isotopic composition (dD) of the n-alkanes was then used to disentangle seasonal and annual precipitation signals.

    The analysis of Sumatran GDGTs revealed that bacterial community shifts of the GDGT producers had a strong impact on reconstructed temperatures, and that H-shaped branched GDGT isomers are good tracers of such community shifts. The branched GDGT temperature reconstruction indicates gradual warming over the Holocene, consistent with models and nearby marine records.

    Rainfall seasonality has shifted drastically over the studied time frame, in particular during the end of the Late Glacial, and between 6-4.2 ka BP. The Late Glacial climate was characterized by a much stronger seasonality, with a cold and dry Asian winter monsoon suppressing atmospheric deep convection in the region. The resulting mean state conditions resembled the atmospheric circulation and sea surface temperature patterns during extreme El Niño events in the modern climate. The Mid-Holocene (6-4.2 ka BP) was characterized by increased seasonality, with alternating droughts and heavy rains due to strong monsoon precipitation and longer dry season.

    The Early Holocene was relatively dry. Wetter conditions started around 7-6 ka BP, and peaked at 4.5-3 ka BP. This is consistent with a dD reconstruction on Sulawesi, but 1.5-2 ka later than indicated by speleothem oxygen isotopic (d18O) records on Sumatra and Sulawesi. However, the speleothem records closely follow algal dD values, interpreted here as a seasonal monsoon signal, suggesting that speleothems in the region reflect monsoonal precipitation rather than an annual signal. Rapid drying was reconstructed for the Late Holocene, starting at 3 ka BP, co-occurring with the onset of strengthened ENSO variability. The Late Holocene drying caused drying out and decomposition of peat in one of the studied cores which resulted in a hiatus of 1700 years, highlighting the importance of hydroclimate for peat and carbon accumulation in tropical wetlands.

    In conclusion, this dissertation enhances our understanding of past climatic conditions in the Maritime Continent and contributes toward constraining the evolution of temperature, precipitation, and monsoon-driven seasonality over the Late Glacial and Holocene in a region that has a scarce coverage of paleoclimate proxy information. Additionally, the methodological aspects of this thesis advance terrestrial paleoclimatological reconstructions by constraining source shifts of GDGTs and proposing a novel approach to disentangle seasonal and annual precipitation signals from dD.

    Trädgårdens textur: Rumsliga, materiella och sociala perspektiv på den privatägda trädgården i Sverige cirka 1900-19302024Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The subject of this dissertation is privately owned gardens in Sweden circa 1900–1930 and aims to identify and make visible their meaning and impact on different societal levels. Sweden, like many other European countries, faced profound societal changes during the nineteenth and early twentieth centuries. This was in part due to a major increase in population, the development of new urban environments, a growing working class, and migration within and out of the country. The culmination of these circumstances had an impact on the development of society, more broadly, and on housing, in particular.

    Prior scholarly inquiries across multiple disciplines have studied the home as a locus for various social relations and expressions of aesthetic ideals. However, the outdoor space of the home has not been specifically included or emphasized in previous research. The focus of this dissertation is therefore to examine gardens within the private sphere – in physical form as well as in their conceptions –  concentrating on spatial organization and material constitution within the social context of the time. The aim is to make visible the ways in which the garden acted as an important part of the construction of the ideal home, in theory as well as in practice. In so doing, gardens and garden practices of the early twentieth century are historically, culturally, and socially situated.

    The theoretical framework is built upon the concept of texture which combines the theoretical fields of spatial theory and materiality. The approach and the use of texture emphasize the material elements that are essential in the constitution of the garden (but not always considered meaningful in their own right), as well as the relationship between humans and their surroundings, particularly with regard to home-making and relating practices. It includes analyses of individual materials’ physical conditions and the way they are experienced with the senses. Furthermore, it highlights the material and visual merging of materials as a perceived whole and the relation of the parts to that whole. Finally, it elucidates the socio-cultural relations between objects and environments which are then experienced, used, and changed by human subjects. 

    The dissertation demonstrates the various meanings of the garden and garden practices, based on a vast set of empirical sources selected on principles of geographical and demographical diversity during the selected time period. The result is presented in case studies. These include analyses of garden literature, the work of county gardeners employed by the Agricultural Society, and educational institutions such as Lillie Landgren’s Torshäll (Dalarna County). Furthermore, particular sites are investigated, such as the mining town of Boliden (Västerbotten County), and the private gardens of Crown Princess Margareta at Sofiero (Skåne County) and Ellen Key at Strand (Östergötand County). The study reveals the multifaceted functions of the garden. The conception of the garden’s potential was made visible in publications and visual material, which provided exemplary gardens, cultivated by – and at the same time cultivating – the human actors. The study’s emphasis on the manual elaboration of materials with a certain aesthetic ideal or practical purpose as the objective confirms that the garden is a result of spatial, material, and social prerequisites, all coalescing as the texture of the garden.

    Förskollärares erfarenheter i arbetet av inkludering i socioekonomiskt utsatta områden: En kvalitativ studie om hur förskollärare samtalar om sina erfarenheter kring arbetet om inkludering i mångkulturella förskolor2024Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att uppmärksamma förskollärare verksamma i socioekonomiskt utsatta områden samtalar om sitt arbete kring att inkludera alla barn i en mångkulturell förskoleverksamhet. Studien utgår från en kvalitativ metod med semistrukturerade intervjuer. Intervjuerna verkställdes med stöd av en intervjuguide och diskussionsfrågor där intervjupersonerna kunde svara fritt. Resultatet visade att det centrala i arbetet med inkludering för mångkulturella barn kategoriseras utifrån sex teman: samtal och aktiviteter som uppmärksammar kulturella olikheter, inkludering genom att arbeta i olika grupper och teman, inkludering genom att uppmärksamma olika språk, besök utanför förskolans arena, interkulturella kompetenser kräver utbildad personal, utmaningar som kan uppkomma i en mångkulturell barngrupp. Det som uppmärksammades och som var avgörande i arbetet med mångkulturella barn var vilka olika strategier förskollärare använde för att inkludera alla barn i socioekonomiskt utsatta områden.

    The effect of variable +/– few elements and the mediation of proficiency level on writing task2024Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det här examensarbetet utformas inom TBLT forskningsområdet, dvs. uppgiftsbaserad språkundervisning (Task-based Language Teaching) och utvecklingen av inlärares skriftliga målspråksperformans. TBLT-forskning har bevisat att kognitiv uppgiftskomplexitet manipulation har en tydlig påverkan på inlärares produktions. Detta visas i specifika aspekter i målspråksproduktionen. TBLT-forskning präglas dock av motstridiga studieresultat när det gäller hur den kognitiva manipulationen påverkar lingvistiska dimensioner. I syfte att undersöka effekten av uppgiftskomplexitets manipulation, presenteras detta examensarbete med empiriskt fokus på de lingvistiska dimensionerna korrekthet, komplexitet och flyt (CAF dimensions) i skolelevers skriftliga produktioner. Dessutom undersöker examensarbetet hur elevernas språkliga kompentens ytterligare kan påverka effekten av manipulationen. Examensarbetets bakgrund, diskussion och slutsats grundas på två teoretiska modeller, Cognition Hypothesis (Robinson, 2003, 2005, 2007) och Trade-off Hypothesis (Skehan, 1998, 2015). Dessa förklarar manipulationseffekten i uppgiftskomplexitet på olika och kontrasterande sätt. I detta examensarbete undersöks 72 svenska gymnasieelevers skriftliga produktioner i engelska genom två versioner (enkel vs. komplex) av en argumenterande uppgift. Resultaten visar att den komplexa versionen bara har få skillnader och inom dessa visas en större effekt i lexikalisk komplexitet. Manipulationen av uppgiftskomplexitet visar ytterligare större effekt bland elever med högre språklig kompetensnivå. Sådana resultat innefattar betydelsefulla pedagogiska tillämpningar för klassrummets praktik, för uppgiftsutformning och val, samt för lärares arbete.

    Kronofogdemyndighetensansvar för felaktiga uppgifter vid exekutiv försäljning: Smyckets vikt2024In: Juridisk Tidskrift, ISSN 1100-7761, E-ISSN 2002-3545, Vol. Net, no 3, p. 320-338Article in journal (Refereed)
    Abstract [sv]

    Statens möjligheter till utmätning och tvångsvis försäljning av egendom kan ses som en nödvändig del i en rättsstat för att säkerställa borgenärers rätt till betalning från gäldenärer som kanske inte vill, men åtminstone kan (som ägare av viss egendom), betala sina skulder. Vid försäljningen utgör staten – genom Kronofogdemyndigheten (KFM) – en förmedlare av ett särskilt slag. Vid exekutiv försäljning av egendom kan fråga därför uppkomma om statens ansvarför fel i den sålda egendomen. Eftersom försäljningen sker inom ramen förmyndighetsutövning, får överlåtelsen en offentligrättslig karaktär. I rättsfallet Smyckets vikt NJA 2023 s. 373 har HD kommit med klargöranden kring statens skadeståndsansvar för felaktiga uppgifter vid sådan försäljning. Ur ett allmänt skadeståndsrättsligt perspektiv innehåller domen få nyheter. Från den exekutionsrättsliga specialregleringens horisont är emellertid domen ett välkommet klargörande av myndighetsansvaret i en specialreglerad – och i skadeståndshänseende till synes oreglerad – försäljningssituation. Domen klargör också att det finns flera tänkbara vägar framåt för en skadelidande i dessa situationer. Eftersom det rör sig om en typ av försäljningssituation som är frekvent förekommande kan domen också antas vara av stor betydelse i praktiken.

    Relationship between wildlife and tourism - interdisciplinary insights from Arctic fox tourism in Sweden2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Interactions between wildlife and tourism can be studied from several different perspectives and the effects of such interactions can influence animals both positively and negatively with effects on both individual and population levels. This thesis takes an interdisciplinary approach, combining both natural and social perspectives, when studying the effects of tourism activity on a small population of the endangered arctic fox (Vulpes lagopus). We have studied arctic foxes inhabiting disturbed and undisturbed den sites in Helagsfjällen, which is the southernmost population of arctic foxes in Sweden and a popular area for recreational activities such as hiking, skiing and camping. The overall objective of the thesis has been to contribute to good management of both arctic foxes and tourism within the study area, as well as to contribute with a comprehensive study of simultaneous disturbance effects and fitness consequences of wildlife tourism activities to the scientific field of wildlife-tourism interactions. The first two papers focus on different aspects of behavioral responses of arctic foxes towards human activity, the third paper evaluates potential fitness consequences and the fourth paper focus on the tourist aspect of the interaction. Behavioral changes in response to tourism disturbance that have been identified in the foxes include changes in vigilance and probability of hiding (Paper I), temporal activity shift at the den site (Paper II) and increased tolerance to human activity (Paper I, Paper II). Juvenile summer survival was higher at disturbed dens compared with undisturbed dens during years of declining small rodent densities (Paper III). Small rodent decline years is when the predation on arctic foxes is presumed to be highest and we suggest that the positive fitness effect could be mediated by a human-induced predator refuge for the foxes in close proximity of human activity. On the tourist aspect, we have identified effects on behavior, knowledge and awareness of the situation for arctic foxes and related conservation work (Paper IV). Overall, results in this thesis showed a high level of context-dependency, which highlights the importance of considering factors such as food availability, intra-species interactions and individual traits such as previous experience with humans. Consequently, the work in this thesis together with ongoing studies of hormonal stress responses constitutes one of the more comprehensive scientific studies of tourism effects on terrestrial mammals. The output from this thesis brings important deliverables for species-specific management and conservation, but also for other species given the rapidly growing interest for wildlife tourism.

    "Det blir enklare att tänka": Bilden som representation i matematiska textuppgifter2024Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    När elever möter matematik i svenska klassrum är det ofta i form av enskilt arbete. Det enskilda arbetet sker i läroböcker och eleverna läser, avkodar, tolkar och räknar till stor del på egen hand. Matematiska läroböcker innehåller bilder av olika slag som medföljer flera uppgifter i böckerna. Bilder verkar därmed utgöra en stor del av elevers matematiska upplevelser och ansågs därför vara intressant att undersöka djupare. Studiens syfte var att utveckla en djupare kunskap om bildens betydelse för elever i matematik. Detta för att bringa uppmärksamhet till bilder inom matematik för lärare att ta del av. Datamaterialet samlades in med hjälp av två test bestående av nio textuppgifter, ett med medföljande bilder till uppgifterna och ett utan bilder, som genomfördes på totalt 30 elever. Därefter genomfördes åtta semistrukturerade intervjuer med fyra elever från vardera test. Data analyserades med hjälp av Leshs teoretiska modell av representationsformer med fokus på elevernas förmåga att lösa uppgifter där text och bild kombineras. Resultatet från studien visade att bilden verkade kunna fungera som ett stöd vid lösning av textuppgifter. Däremot verkade vissa bilder fungera bättre än andra. Det visade sig även att elever som saknade bilder till uppgifterna i större utsträckning använde sig av egenkonstruerade bilder i sina lösningar. Eleverna delgav en positiv syn om bilder kombinerat med textuppgifter men beskrev användandet som situationsberoende. Eleverna beskrev sig använda bilderna om de hade ett tydligt matematiskt syfte annars ansågs de onödiga. Bilden verkar vara viktig för eleverna oavsett om den ges till dem eller om eleverna själva skapar dem, dock med reservation att bilden ska presentera ett matematiskt innehåll för att undvika vilseledning.

    Dags att njuta: En semiotisk analys av hedonistiska teman i svensk destinationsmarknadsföring2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med undersökningen är att visa på vilka sätt marknadsföring av svenska destinationer använder sig av hedonistiska teman för att övertyga läsaren. Detta undersöks genom att studera hur hedonistiska teman uttrycks genom text, bild och samspelet mellan text och bild. Studien fokuserar på fyra teman med hedonistisk grund: frihet, närvaro, autenticitet, samt spänning. Dessa teman identifieras i materialet med hjälp av semiotisk analys hämtad från Roland Barthes. Studiens material är utdrag från webbplatser från destinationsbolagen för Gotland, Höga Kusten och Skåne. Analysen visar att dessa hedonistiska teman uttrycks i bild med hjälp av komposition, bakgrundsmiljöer, ljusförhållanden, föremål, ansiktsuttryck, handlingar och personlig stil. De visuella medlen fungerar både på en denotativ och konnotativ nivå. Temana uttrycks i text genom formuleringar som nyttjar denotativ och konnotativ betydelse i olika hög grad och några återkommande sätt att hämta konnotationer är genom yrken, aktiviteter och utländska platser. Analysen av samspelet mellan text och bild visar att samspelet kan förstärka, förändra och skapa både denotativ och konnotativ betydelse tillsammans, men att potentialen i samspelet ibland inte nyttjas. Analysen visar också att materialet i högre grad kommunicerar genom bild än genom text.

    Rekrytering av rekryter: En multimodal textanalys av Försvarsmaktens rekryteringsinlägg på Instagram2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I denna uppsats undersöks vilka modelläsare som skapas i nio olika rekryteringsinlägg på Försvarsmaktens Instagram-konto. Undersökningen tar avstamp i en multimodal textanalys som baseras på systemisk-funktionell grammatik. Resultatet visar att de modelläsare som konstrueras i grunden delar samma egenskaper – de är handlingskraftiga, drivna och initiativtagande, men utöver det konstrueras varje modelläsare med unika egenskaper och förutsättningar. Resultatet visar även att det finns skillnader på hur modelläsare konstrueras beroende på om värnplikten är vilande eller aktiv. Gemensamt för samtliga modelläsare är att relationen till Försvarsmakten bygger på att Försvarsmakten erbjuder något som modelläsaren söker.

    Svenska institutet som vägvisare och utbildare: En kritisk diskursanalys av subtila hierarkier2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats är att undersöka om det finns tendenser av postkolonial ideologi i texter som rör utbildning hos myndigheten Svenska institutet. Studien granskar sju artiklar som publicerades på Svenska institutets hemsida under våren 2022. Genom kritisk diskursanalys ställs frågor kring hur maktutövning och dominans uttrycks genom det språk som används för att beskriva svenska och icke- svenska deltagare. Resultaten visar att Svenska institutet riskerar att förstärka och reproducera idéer om Väst som mer kompetent än Öst, genom lexikogrammatiska val som framställer svenska deltagare som framträdande, handlingskraftiga och inflytelserika, medan icke-svenska deltagare i högre grad återfinns i satsers periferi. Samtidigt finns motsägelser i studiens material, där lexikogrammatiska val döljer svenska deltagare och därigenom lyfter icke-svenska deltagare. Därtill tillskrivs icke-svenska deltagare fördelaktiga egenskaper och attribut, vilket skapar en positiv bild av dem. Avslutningsvis diskuteras om Svenska institutets alumnverksamhet kan tänkas vara ett medel genom vilket Sverige kan öka det egna anseendet, samt få större ekonomisk framgång.

    Sexarbete - Vad är problemet?: En diskursanalys av statens offentliga utredningar2022Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study aims to explore how sex work is presented as a problem in relation to gender in the state’s public investigations. Using Carol Bacchis (2009) discourse analysis method What's the problem represented to be?, two public investigations where analyzed. Report könshandel (SOU 1995:15) where an important step in the process of making it illegal to buy sex but legal to sell in Sweden, and the second public investigation is an evaluation (SOU 2010:49) of how the law has worked in practice since it was implemented.

    The study shows that the problem with sex work is presented as a question about equality, where sex work represent inequality. Throughout the investigations the representation of the ‘problem’ is directly affected by the gender of the person described. And the main result shows that sex work as a problem is focused on descriptions of the female sex worker and mens violence against women. Which has affected the way we work with people in sex work, the earlier language that focus on women have influenced social work today and how the resources are distributed. Males and transgendered people have been set aside in working with people in sex work.

    Finns en påtaglig risk för tvångsäktenskap eller könsstympning?: En innehållsanalys av domar rörande utreseförbud enligt LVU2022Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to learn how the utreseförbud is applied in the Swedish judiciary. The law is one of the preventive measures introduced to protect children from honor-related violence and oppression. Utreseförbudet aims to protect children when there is a substantial risk for the child to be taken abroad for the purpose of entering into a forced marriage or being exposed to female genital mutilation. This study examines how the substantial risk in the law is described by the social welfare board and how the court assesses the substantial risk. The empirical material of the study consists of the 27 judgements made so far, concerning utreseförbudet. The material was examined through a content analysis and analyzed using the central theoretical concepts: honor, control mechanisms to maintain the ideal of virginity and discretion. Based on the results of the study, it emerged that utreseförbud is issued when the social welfare board and the court both have extensive knowledge of honor and when the circumstances described are considered concrete. Finally, it is discussed whether the law should be extended to include all forms of abduction in an honor context.

    ChatGPT vs. Teacher Feedback Provision: An investigation on the efficacy of ChatGPT feedback provision on written production across proficiency levels2024Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Framväxten av artificiell intelligens (AI) och generativ AI har lett till lanseringen av AI-baserade chatbottar som OpenAI:s ChatGPT. Det är i stort sett fortfarande oklart vilken effekt användningen av dessa verktyg har på undervisning i engelska som främmande språk. Den empiriska undersökningen som presenteras i detta examensarbete har därför syftet att undersöka vilken effekt ChatGPT-feedback har i jämförelse med lärarfeedback på svenska gymnasieelevers komplexitet, korrekthet och flyt i skriftlig produktion på engelska. Ett ytterligare mål med denna studie var att undersöka om elevernas språkliga kompetens påverkar dessa effekter. Studien genomfördes genom att undersöka 56 gymnasielevers argumenterande texter före och efter feedback. Studiens resultat pekar på att båda feedbackmodaliteter har liknande effekt på elevernas komplexitet, korrekthet och flyt. Statistiskt signifikanta ökningar går att se i dimensionerna för korrekthet, lexikal komplexitet och flyt för båda feedbackmodliteter. För dimensionen syntaktisk komplexitet har endast ChatGPT gruppen nått en statistiskt signifikant ökning, och för korrekthet har Lärarfeedback haft en större effekt med statistiskt signifikanta ökningar inom alla fyra analytiska mått för dimensionen. Vidare visar studien att elever med lägre språklig kompetens gynnas mer av feedbacken än elever med högre språkliga kompetens. Studien belyser även behovet av att framtida forskning fokuserar på ChatGPT-feedbacks effekter på texters generella kommunikativa funktion för att bättre förstå vilka effekter AI-genererad feedback har på skriftlig produktion i engelska som främmande språk.

    Gängkriminalitetens terror(ism)?: En tematisk analys av gängkriminalitet och terrorism i svensk dagspress2023Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Senaste årens ökning av det dödliga våldet kopplat till konflikter inom den kriminella miljön hargenererat i åtskilliga debatter och diskussioner i Sverige. Somliga menar att gängkriminalitetenär landets “nya terrorism”, och att den kriminalpolitiska riktningen behöver forma sig utifråndetta. Syftet med föreliggande studie är således att undersöka hur ledarskribenter i svenskaledarartiklar framställer gängkriminalitet och kriminella nätverk respektive terrorism ochextremism från år 2015 till och med 2022, samt hur detta kan förstås och analyseras över tid.Med en teoretisk utgångspunkt i den goda fienden, hotbilder och alarmism samt influenser avtidigare forskning som bedrivits om medier och moralpanik så gjordes en tematisk analys avsammanlagt 128 svenska ledarartiklar från Aftonbladet, Expressen, Svenska Dagbladet ochDagens Nyheter. De analytiska temana som skapades ur materialet var folkdjävlar och fiender,hotets karaktär och kriminalpolitisk kontext. Studiens analys förhöll sig till materialetskontinuitet och förändring över tid; och urskiljde således övergångar och förskjutningar därdiskursen om gängkriminalitet och kriminella nätverk gradvis närmade sig den om terrorism ochextremism. Studiens resultat identifierar kontexter och tidsperioder i ledarartiklarna därframställningen av dessa fenomen på olika sätt 1) skiljer sig från varandra 2) närmar sig varandraeller 3) överlappar varandra. Avslutningsvis så hänvisas studiens analytiska fynd till denteoretiska inramningen och belyser eventuella orsaker och konsekvenser av den påvisadediskursen.

    Abstract [en]

    This study seeks a deeper understanding of how guidance counselors experience the work with perspective broadening, giving information about the labor market and what effects those might have on students in upper secondary vocational education. This will be achieved through qualitative interviews with eight guidance counselors in Sweden. The guidance counselors experience that perspective-broadening counseling is important for the students. It opens up alternative routes. The ability to choose a path within studies and jobs leads to better career choices. There was a concern among the respondents about sounding derogatory to the students' chosen industry as a result of perspective-broadening guidance. To some extent, this affects how the guidance counselors work with broadening perspectives and express themselves to students. The work with labor market information varies between the respondents but is perceived as important for students' contact with working life and knowledge of changes in the labor market. Work-based learning (practice) and the vocational teachers' knowledge of the students' intended industries are perceived as significant. The guidance counselors primarily provide labor market information on other industries if there is interest in this.

    Regime shifts, unequal adaptive capacities and the Commons: Exploring behavioural responses in a laboratory experiment2023Independent thesis Advanced level (degree of Master (Two Years)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Relentless overexploitation of natural resources has led to resource scarcity, environmentaldegradation and rising inequalities, straining social-ecological systems to breaking point.Ecosystems providing shared resources often respond non-linearly to resource pressuresbeyond critical thresholds, so-called regime shifts, jeopardizing the stable and just provisionof natural resources. Avoiding these critical thresholds is imperative, as not everyone canadapt to drastic changes in resource availability and distribution. In an unequal world wherecapacities to adapt to crossing critical thresholds vary substantially across individuals, groupsand countries, our understanding of behavioural responses remains limited. This thesisexplores whether and how inequality in adaptive capacities within groups sharing a naturalresource influence both the likelihood of groups crossing a critical threshold and groupdynamics. 160 students from the University of Exeter participated in an online Common-PoolResource (CPR) laboratory experiment comparing inequality and baseline treatments. Whileunequal adaptive capacities did not affect group’s likelihood of crossing the threshold, theynegatively impacted social dynamics and perceptions. Participants with low adaptive capacity(LAC) responded to the threat of the threshold by reducing their harvest significantly whencompared to participants with high adaptive capacity (HAC). Therefore, latent inequalities inthe choice context created real inequalities in resource allocation. Furthermore, HACparticipants lacked identification with the disadvantaged group as evidenced by lowerperceived group efficacy and no reduction in harvest. When the harvest was shared unequally,inequalities were more pronounced in the inequality treatment compared to the baseline.Investigating emotions revealed unexpected findings: Participants did not strongly experienceguilt despite its relevance in prior research, instead, positive emotions, particularlycompassion, were prominent across treatments despite non-cooperative outcomes. Whileresults caution against assuming solidarity of the privileged group solely based on awarenessof unequal impacts, future research might consider fairness, beyond inequalities, tounderstand collective behaviours in unequal contexts.

    Digitaliseringens påverkan på slöjdämnet i grundskolan2024Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study discusses the impact of digitalization on the crafts subject in primary school. How sloydteachers and students use digital technology and how sloyd teachers perceive the opportunities and obstacles digital technology has for craft teaching.The study includes both the hermeneutic and the positivist view of knowledge. By combining these approaches, the investigation is given a greater depth regarding my research questions.The research questions were answered through a survey. The survey, which consisted of both multiple-choice and open-ended questions, was sent out electronically to three selected groups on Facebook. When 38 responses were received, the analysis was initiated.The results show that a large majority view the use of digital technology in crafts teaching positively and that it provides great or relatively great opportunities to, for example, explore modern manufacturing technology, increase motivation for students and increase interdisciplinary collaboration between crafts and other subjects. The result also shows that the actual use is widespread and effectively integrated regarding the general digital devices. The use of subject-specific digital devices, such as laser cutters, CAD programs, cutting plotters, etc., is shown in the results report.

    Oro eller hopp - undervisning för hållbar utveckling: En kvalitativ intervjustudie av mellanstadielärares erfarenheter och intentioner2023Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att undersöka hur mellanstadielärare beskriver sin planering och undervisning för hållbar utveckling inom ramen för geografi ämnet. Studien ämnar även att undersöka möjliga skillnader mellan olika socioekonomiska områden i Stockholms län och vilka anpassningar lärare gör för att undvika framtidsoro. Detta är en kvalitativ intervjustudie där empirin utgörs av sex lärarintervjuer, där samtliga undervisar inom alla SO-ämnen. Resultatet visar en genomgående önskan om och behov av att arbeta ämnesöverskridande med ämnet, men att tiden för detta inte finns. Alla lärare berättar att deras elever i olika mån uttrycker oro kopplat till klimatförändringar, men det framkommer också att en tredjedel av lärarna upplever ett ointresse och bristande engagemang blandeleverna för ämnet. Det som väcker elevernas intresse uttrycks vara verklighetsförankrat arbete och naturkatastrofer, trots att det bidrar med spridda känsloyttringar hos eleverna. Vidare framgår det även att skolor inom socioekonomiskt svaga områden behöver lägga mer tid och fokus på språkutvecklande arbetssätt, begreppsförståelse och faktabaserad undervisning. Detta fokus i undervisningen beskrivs bero på elevernas förkunskaper i ämnet och deras språkkunskaper. Skillnader beroende på socioekonomiska områden är även kopplade till vad elevernas föräldrar har för inställning till ämnet, vilket speglar lärarnas utformning av undervisningen, där målet blir att utvidga och nyansera elevernas syn på ämnet.

    Modelling and Detecting Kilonovae in the Rubin Observatory Era2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Survey astronomy is a powerful tool for discoveries in astrophysics and cosmology. In the coming years, this field will be revolutionised with the start of the ten-year Legacy Survey of Space and Time (LSST), to be conducted at the Vera C. Rubin Observatory. This survey, with its unique capabilities in temporal sampling, single-image depth and covered sky-area, will explore a new discovery space for astrophysical transients in the Universe. The 2017 discovery of an electromagnetic and gravitational-wave transient presents a unique opportunity to influence the design of the LSST observing strategy for the detection of binary neutron star (BNS) mergers. This will be scientifically beneficial, not only for studies of the astrophysics of these sources, but also for developing new cosmological probes. Given the sensitivity of the Rubin Observatory, it is expected that this instrument will detect these binary neutron star mergers to greater distances than detectable by current and near-term gravitational wave detectors. This presents further opportunities to study the characteristics of the BNS population that will be selected into these surveys. If we understand the underlying BNS merger population and associated electromagnetic emission, it may also be possible to recover the previously undetected counterpart gravitational wave signals.

    In this thesis I discuss kilonovae (kNe) from BNS mergers with a focus on detection of kNe in the LSST survey. I will discuss the physics and modelling of kNe, including my work incorporating a viewing-angle dependence in the optical light curve modelling of BNS kNe. After setting the context for the Rubin Observatory and the LSST, I will describe work on optimising the observing strategy of the LSST to detect kNe from BNS mergers and the observing strategy features that impact detection. This work also indicates that a portion of the BNS mergers associated with kN detections in the LSST will be below the threshold for detection of their gravitational wave emission. Furthermore, I will discuss modelling a population of kNe from BNS mergers that is consistent with each merger’s associated gravitational-wave signal. This modelling includes a dependence of the kN on nuclear physics calibrated with detailed emulation of radiation-transport simulations. I conclude by summarising the scientific impact of this research and discussing future directions, such as: studying the BNS multi-messenger observational selection function for the LSST and concurrent gravitational wave detectors, detection of subthreshold signals, and the problem of classifying kN light curves.

    Securing IoT Using Decentralized Trust Privacy and Identity Management2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The Internet of Things (IoT) is a multidisciplinary area where technology meets people, enriching their quality of life with an improved working environment and efficient productivity. As the number of IoT devices increases, many new technology areas are being integrated with the IoT. IoT devices mainly connect and collaborate with central cloud servers for data management. The IoT paradigm is built upon the Internet and accesses different layers of Internet architectures. IoT devices are at the access layer of the Internet, and cloud servers are located at the top layer. The innovative use cases of IoT applications drive the requirement for quick decision-making that occurs as close to the source of information as possible. IoT devices need to be authenticated near the source for rapid request processing. Trustworthy interaction and secure communication between different entities of an IoT paradigm are crucial. A centralized cloud-based implementation of IoT solutions can be problematic for ensuring trustworthy and authenticated interactions in which quicker decision-making is involved. Additionally, privacy leakage possibilities increase with cloud-based solutions, as they involve multiparty interactions, introducing more complexity into ensuring data privacy. Due to IoT application and service heterogeneity, traditional security models are unsuitable for the IoT. There is no generic model for IoT data security and user data privacy that can facilitate trustworthy collaboration and identity management near the source.

    The thesis focuses on creating a generic state-of-the-art artefact for IoT security, utilizing decentralized trust, user data privacy, and localized identity management for heterogeneous IoT devices and services. The main contributions of this thesis include a novel decentralized model for secure and reliable interaction between components of the IoT paradigm, complemented by a decentralized trust management model, an edge gateway-based privacy enhancement scheme, and a decentralized identity management model with new authentication and authorization mechanisms for IoT devices where access to new resources is granted locally, and activities are recorded with context information. The proposed models are generic and can be easily adapted to real-life IoT use cases with minor amendments.

    Conversational production and comprehension: fMRI-evidence reminiscent of but deviant from the classical Broca–Wernicke model2024In: Cerebral Cortex, ISSN 1047-3211, E-ISSN 1460-2199, Vol. 34, no 3Article in journal (Refereed)
    Abstract [en]

    A key question in research on the neurobiology of language is to which extent the language production and comprehension systems share neural infrastructure, but this question has not been addressed in the context of conversation. We utilized a public fMRI dataset where 24 participants engaged in unscripted conversations with a confederate outside the scanner, via an audio-video link. We provide evidence indicating that the two systems share neural infrastructure in the left-lateralized perisylvian language network, but diverge regarding the level of activation in regions within the network. Activity in the left inferior frontal gyrus was stronger in production compared to comprehension, while comprehension showed stronger recruitment of the left anterior middle temporal gyrus and superior temporal sulcus, compared to production. Although our results are reminiscent of the classical Broca–Wernicke model, the anterior (rather than posterior) temporal activation is a notable difference from that model. This is one of the findings that may be a consequence of the conversational setting, another being that conversational production activated what we interpret as higher-level socio-pragmatic processes. In conclusion, we present evidence for partial overlap and functional asymmetry of the neural infrastructure of production and comprehension, in the above-mentioned frontal vs temporal regions during conversation.

    Inconsistencies and missing links in EU chemicals legislation2024Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The EU chemicals legislation consists of the Regulation on Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) and the Regulation on Classification, Labelling, and Packaging of Substances and Mixtures (CLP), complemented by over fifty regulations and directives regulating specific uses and products. While regulating individual uses may offer a faster and simpler approach to protecting human health and the environment from hazardous chemicals, it can also lead to inconsistencies, such as gaps and overlaps. These inconsistencies may arise for chemicals with multiple uses, each governed by separate legislation.

    The overall objective of this work was to understand the links between different pieces of EU chemicals legislation, to identify inconsistencies in the regulation of chemicals covered by multiple regulations and, in particular, to explore the implications of these inconsistencies for the protection of human health and the environment. First, we compared how antimicrobial substances are regulated when used in biocidal products compared to cosmetics (Paper I). The risk assessment of cosmetic preservatives focused solely on human health, omitting environmental data and environmental risk assessment. Once granted, the approval of cosmetic preservatives remained valid indefinitely until revoked by the European Commission, with no requirement to update the dossier based on new information. Based on these findings, we examined whether the approved cosmetic preservatives were hazardous to the aquatic environment or persistent, and if so, whether the risks were efficiently managed by REACH (Paper II). The analysis showed that environmental hazards of cosmetic preservatives and other ingredients are overlooked by the Cosmetic Products Regulation and might not be effectively managed by REACH. Next, the linkage between the CLP and other pieces of chemicals legislation was examined, mapping out regulatory obligations, arising from the new CLP hazard classes for endocrine disruption for human health (ED HH), endocrine disruption for the environment (ED ENV), PBT/vPvB, and PMT/vPvM (Papers III and IV). Meeting criteria for human health hazards under the CLP triggered more regulatory obligations across multiple regulations, compared to when fulfilling the criteria for physical or environmental hazards. Implementation of the new CLP hazard classes will require revision of regulations with existing risk management measures connected to the CLP hazard criteria.

    The results and conclusions of the studies included in this thesis highlight the need for addressing the existing inconsistencies in order to strengthen the protection of human health and the environment. The provided recommendations address the need for harmonisation of the chemicals legislation and more efficient management of hazardous chemicals.

    A Tale of Two Laureates: Nadine Gordimer, J. M. Coetzee and the Swedish Press2024In: Journal of World Literature, ISSN 2405-6472, E-ISSN 2405-6480, Vol. 9, no 1, p. 7-23Article in journal (Refereed)
    Abstract [en]

    Focusing on the reception of the two Nobel laureates Nadine Gordimer and J.M. Coetzee,this article investigates the literature prize as a national, and indeed Stockholmbased,phenomenon in Sweden. It makes two general claims. The first is that the press exercises a co-consecrating authority that both rivals and depends on the authority of the Swedish Academy. This becomes evident not least in occasional attempts by critics to deconsecrate a laureate. The second claim is that the dramaturgy of the literatureprize, beginning with the announcement in October and ending with the award ceremony in December, culminates shortly before the ceremony with the Nobel lecture,when the laureate is heard in their own voice. In an analysis of Gordimer’s and Coetzee’s lectures, the article concludes that they present sharply different attempts at performatively resolving the tension between literary autonomy and heteronomy.
