    The Intrinsic Activity of the Brain and Its Relation to Levels and Disorders of Consciousness2017In: Mind and Matter, ISSN 1611-8812, E-ISSN 2051-3003, Vol. 15, no 2, 197-219 p.Article in journal (Refereed)
    Abstract [en]

    Science and philosophy still lack an overarching theory of consciousness. We suggest that a further step toward it requires going beyond the view of the brain as input-output machine and focusing on its intrinsic activity, which may express itself in two distinct modalities, i.e. aware and unaware. We specifically investigate the predisposition of the brain to evaluate and to model the world. These intrinsic activities of the brain retain a deep relation with consciousness. In fact the ability of the brain to evaluate and model the world can develop in two modalities, implicit or explicit, that correspond to what we usually refer to as the unconscious and consciousness, and both are multilevel configurations of the brain along a continuous and dynamic line. Starting from an empirical understanding of the brain as intrinsically active and plastic, we here distinguish between higher cognitive functions and basic phenomenal consciousness, suggesting that the latter might characterize the brain’s intrinsic activity as such, even if at a very basic level. We proceed to explore possible impacts of the notion of intrinsic cerebral phenomenality on our understanding of consciousness and its disorders, particularly on the diagnosis and management of patients with disorders of consciousness.

    Resurrecting ancestral genes in bacteria to interpret ancient biosignatures2017In: Philosophical Transactions. Series A: Mathematical, physical, and engineering science, ISSN 1364-503X, E-ISSN 1471-2962, Vol. 375, no 2109, 20160352Article in journal (Refereed)
    Abstract [en]

    Two datasets, the geologic record and the genetic content of extant organisms, provide complementary insights into the history of how key molecular components have shaped or driven global environmental and macroevolutionary trends. Changes in global physico-chemical modes over time are thought to be a consistent feature of this relationship between Earth and life, as life is thought to have been optimizing protein functions for the entirety of its approximately 3.8 billion years of history on the Earth. Organismal survival depends on how well critical genetic and metabolic components can adapt to their environments, reflecting an ability to optimize efficiently to changing conditions. The geologic record provides an array of biologically independent indicators of macroscale atmospheric and oceanic composition, but provides little in the way of the exact behaviour of the molecular components that influenced the compositions of these reservoirs. By reconstructing sequences of proteins that might have been present in ancient organisms, we can downselect to a subset of possible sequences that may have been optimized to these ancient environmental conditions. How can one use modern life to reconstruct ancestral behaviours? Configurations of ancient sequences can be inferred from the diversity of extant sequences, and then resurrected in the laboratory to ascertain their biochemical attributes. One way to augment sequence-based, single-gene methods to obtain a richer and more reliable picture of the deep past, is to resurrect inferred ancestral protein sequences in living organisms, where their phenotypes can be exposed in a complex molecular-systems context, and then to link consequences of those phenotypes to biosignatures that were preserved in the independent historical repository of the geological record. As a first step beyond single-molecule reconstruction to the study of functional molecular systems, we present here the ancestral sequence reconstruction of the beta-carbonic anhydrase protein. We assess how carbonic anhydrase proteins meet our selection criteria for reconstructing ancient biosignatures in the laboratory, which we term palaeophenotype reconstruction.This article is part of the themed issue 'Reconceptualizing the origins of life'.

    Limit Laws, Homogenizable Structures and Their Connections2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is in the field of mathematical logic and especially model theory. The thesis contain six papers where the common theme is the Rado graph R. Some of the interesting abstract properties of R are that it is simple, homogeneous (and thus countably categorical), has SU-rank 1 and trivial dependence. The Rado graph is possible to generate in a probabilistic way. If we let K be the set of all finite graphs then we obtain R as the structure which satisfy all properties which hold with assymptotic probability 1 in K. On the other hand, since the Rado graph is homogeneous, it is also possible to generate it as a Fraïssé-limit of its age.

    Paper I studies the binary structures which are simple, countably categorical, with SU-rank 1 and trivial algebraic closure. The main theorem shows that these structures are all possible to generate using a similar probabilistic method which is used to generate the Rado graph. Paper II looks at the simple homogeneous structures in general and give certain technical results on the subsets of SU-rank 1.

    Paper III considers the set K consisting of all colourable structures with a definable pregeometry and shows that there is a 0-1 law and almost surely a unique definable colouring. When generating the Rado graph we almost surely have only rigid structures in K. Paper IV studies what happens if the structures in K are only the non-rigid finite structures. We deduce that the limit structures essentially try to stay as rigid as possible, given the restriction, and that we in general get a limit law but not a 0-1 law.

    Paper V looks at the Rado graph's close cousin the random t-partite graph and notices that this structure is not homogeneous but almost homogeneous. Rather we may just add a definable binary predicate, which hold for any two elemenets which are in the same part, in order to make it homogeneous. This property is called being homogenizable and in Paper V we do a general study of homogenizable structures. Paper VI conducts a special case study of the homogenizable graphs which are the closest to being homogeneous, providing an explicit classification of these graphs.

    Abstract [en]

    In this article we give a classification of the binary, simple, ω-categorical structures with SU-rank 1 and trivial algebraic closure. This is done both by showing that they satisfy certain extension properties, but also by noting that they may be approximated by the almost sure theory of some sets of finite structures equipped with a probability measure. This study give results about general almost sure theories, but also considers certain attributes which, if they are almost surely true, generate almost sure theories with very specific properties such as ω-stability or strong minimality.

    Abstract [en]

    We study definable sets D of SU-rank 1 in Meq, where M is a countable homogeneous and simple structure in a language with finite relational vocabulary. Each such D can be seen as a 'canonically embedded structure', which inherits all relations on D which are definable in Meq, and has no other definable relations. Our results imply that if no relation symbol of the language of M has arity higher than 2, then there is a close relationship between triviality of dependence and D being a reduct of a binary random structure. Somewhat more precisely: (a) if for every n≥2, every n-type p(x1,...,xn) which is realized in D is determined by its sub-2-types q(xi,xj)⊆p, then the algebraic closure restricted to D is trivial; (b) if M has trivial dependence, then D is a reduct of a binary random structure.

    Abstract [en]

    We study finite -colourable structures with an underlying pregeometry. The probability measure that is usedcorresponds to a process of generating such structures by which colours are first randomly assigned to all1-dimensional subspaces and then relationships are assigned in such a way that the colouring conditions aresatisfied but apart from this in a random way. We can then ask what the probability is that the resulting structure,where we now forget the specific colouring of the generating process, has a given property. With this measurewe get the following results: (1) A zero-one law. (2) The set of sentences with asymptotic probability 1 has anexplicit axiomatisation which is presented. (3) There is a formula ξ (x, y) (not directly speaking about colours)such that, with asymptotic probability 1, the relation “there is an -colouring which assigns the same colourto x and y” is defined by ξ (x, y). (4) With asymptotic probability 1, an -colourable structure has a unique-colouring (up to permutation of the colours).

    Abstract [en]

    A systematic study is made, for an arbitrary finite relational language with at least one symbol of arity at least 2, of classes of nonrigid finite structures. The well known results that almost all finite structures are rigid and that the class of finite structures has a zero-one law are, in the present context, the first layer in a hierarchy of classes of finite structures with increasingly more complex automorphism groups. Such a hierarchy can be defined in more than one way. For example, the kth level of the hierarchy can consist of all structures having at least k elements which are moved by some automorphism. Or we can consider, for any finite group G, all finite structures M such that G is a subgroup of the group of automorphisms of M; in this case the "hierarchy" is a partial order. In both cases, as well as variants of them, each "level" satisfies a logical limit law, but not a zero-one law (unless k = 0 or G is trivial). Moreover, the number of (labelled or unlabelled) n-element structures in one place of the hierarchy divided by the number of n-element structures in another place always converges to a rational number or to infinity as n -> infinity. All instances of the respective result are proved by an essentially uniform argument.

    Abstract [en]

    A homogenizable structure M is a structure where we may add a finite amount of new relational symbols to represent some 0-definable relations in order to make the structure homogeneous. In this article we will divide the homogenizable structures into different classes which categorize many known examples and show what makes each class important. We will show that model completeness is vital for the relation between a structure and the amalgamation bases of its age and give a necessary and sufficient condition for an countably categorical model-complete structure to be homogenizable.

    In this article we give an explicit classification for the countably infinite graphs G which are, for some k, ≥k-homogeneous. It turns out that a ≥k  -homogeneous graph M is non-homogeneous if and only if it is either not 1-homogeneous or not 2-homogeneous, both cases which may be classified using ramsey theory.

    Abstract [en]

    The purpose of the current case-study is to bring further knowledge to the field of political science of political participation amoung the group assyrians and syriacs in Sweden. Furthermore, the fundamental research question investigate which ways assyrians and syriacs engage in the political field. This thesis utilizes qualitative phase use eight informants collected by social media and snowball sampling technique. The methods of data collection are semi-structured interviews and are collected and analyzed by qualitative content analysis. The result in the study shows that the assyrians and syriacs in Sweden utilize their right as Swedish citizens and their voices to engage with both Swedish politics and assyrians/syriacs causes. They are generally motivated by both the Swedish political issues and by the assyrian/syriac cause.

    Medium Data on Big Data Predicting Disk Failures in CERNs NetApp-based Data Storage System2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    I describe in this report an experimental system for using classification and regression trees to generate predictions of disk failures in a NetApp-based storage system at the European Organisation for Nuclear Research (CERN) based on a mixture of SMART data, system logs, and low-level system performance dataparticular to NetApp's storage solutions. Additionally, I make an attempt at profiling the system's built-in failure prediction method, and compiling statistics on historical complete-disk failures as well as bad blocks developed. Finally, I experiment with various parameters for producing classification trees and end up with two candidate models which have a true-positive rate of 86% with a false-alarm rate of 4% or atrue-positive rate of 71% and a false-alarm rate of 0.9% respectively, illustrating that classification trees might be a viable method for predicting real-life disk failures in CERNs storage systems.

    Comparative study of elemental mercury flux measurement techniques over a Fennoscandian boreal peatland2018In: Atmospheric Environment, ISSN 1352-2310, E-ISSN 1873-2844, Vol. 172, 16-25 p.Article in journal (Refereed)
    Abstract [en]

    Quantitative estimates of the land-atmosphere exchange of gaseous elemental mercury (GEM) are biased by the measurement technique employed, because no standard method or scale in space and time are agreed upon. Here we present concurrent GEM exchange measurements over a boreal peatland using a novel relaxed eddy accumulation (REA) system, a rectangular Teflon (R) dynamic flux chamber (DFC) and a DFC designed according to aerodynamic considerations (Aero-DFC). During four consecutive days the DFCs were placed alternately on two measurement plots in every cardinal direction around the REA sampling mast. Spatial heterogeneity in peat surface characteristics (0-34 cm) was identified by measuring total mercury in eight peat cores (57 +/- 8 ng g(-1), average SE), vascular plant coverage (32-52%), water table level (4.5-14.1 cm) and dissolved gaseous elemental mercury concentrations (28-51 pg L-1) in the peat water. The GEM fluxes measured by the DFCs showed a distinct diel pattern, but no spatial difference in the average fluxes was detected (ANOVA, alpha = 0.05). Even though the correlation between the Teflon DFC and Aero-DFC was significant (r = 0.76, p < 0.05) the cumulative flux of the Aero-DFC was a factor of three larger. The average flux of the Aero-DFC (1.9 ng m(-2) h(-1)) and REA (2 ng m(-2) h(-1)) were in good agreement. The results indicate that the novel REA design is in agreement for cumulative flux estimates with the Aero-DFC, which incorporates the effect of atmospheric turbulence. The comparison was performed over a fetch with spatially rather homogenous GEM flux dynamics under fairly consistent weather conditions, minimizing the effect of weather influence on the data from the three measurement systems. However, in complex biomes with heterogeneous surface characteristics where there can be large spatial variability in GEM gas exchange, the small footprint of chambers ( < 0.2 m(2)) makes for large coefficients of variation. Thus many chamber measurement replications are needed to establish a credible biome GEM flux estimate, even for a single point in time. Dynamic flux chambers will, however, be able to resolve systematic differences between small scale features, such as experimentally manipulated plots or small scale spatial heterogeneity.

    Sentiment analysis of Swedish reviews and transfer learning using Convolutional Neural Networks2018Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Sentiment analysis is a field within machine learning that focus on determine the contextual polarity of subjective information. It is a technique that can be used to analyze the "voice of the customer" and has been applied with success for the English language for opinionated information such as customer reviews, political opinions and social media data. A major problem regarding machine learning models is that they are domain dependent and will therefore not perform well for other domains. Transfer learning or domain adaption is a research field that study a model's ability of transferring knowledge across domains. In the extreme case a model will train on data from one domain, the source domain, and try to make accurate predictions on data from another domain, the target domain. The deep machine learning model Convolutional Neural Network (CNN) has in recent years gained much attention due to its performance in computer vision both for in-domain classification and transfer learning. It has also performed well for natural language processing problems but has not been investigated to the same extent for transfer learning within this area. The purpose of this thesis has been to investigate how well suited the CNN is for cross-domain sentiment analysis of Swedish reviews. The research has been conducted by investigating how the model perform when trained with data from different domains with varying amount of source and target data. Additionally, the impact on the model’s transferability when using different text representation has also been studied.

    This study has shown that a CNN without pre-trained word embedding is not that well suited for transfer learning since it performs worse than a traditional logistic regression model. Substituting 20% of source training data with target data can in many of the test cases boost the performance with 7-8% both for the logistic regression and the CNN model. Using pre-trained word embedding produced by a word2vec model increases the CNN's transferability as well as the in-domain performance and outperform the logistic regression model and the CNN model without pre-trained word embedding in the majority of test cases.

    Maskininlärning i fastighetsbranschen: Prediktion av felanmälningar gällande inomhusklimat baserat på sensordata2017Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates the prerequisites needed for the Swedish real estate company Fabege to create useful machine learning models for classification and prediction of error reports from tenants. These error reports are regarding cold indoor climates and bad indoor air quality. By analyzing the available data, that consists of error reporting data, weather data and indoor climate data, the thesis investigates the different correlations between the sensor data and the error reports. By using an algorithm called decision jungle, two machine learning models have been trained in Microsoft Azure Machine Learning Studio. The main model, trained on error reporting data and weather data, shows the possibilities to classify data instances as a part of different error reporting classes. The model proves that it is possible to predict the emergence of future error reports of different classes with an average accuracy of 78%. The complementary model, trained on a small but more richly annotated dataset consisting of one year of indoor sensor data as well as the above-mentioned data, shows that there is a possibility to improve the main model by using indoor climate data.

    The thesis has shown that for Fabege to expand and improve these models, the amount of data collected from the indoor sensors needs to be largely increased. Fabege also needs to improve the quality of the error reporting data, which could be achieved by improving the error reporting form used by the tenants.

    Cellular responses to amyloid-beta protofibrils: Focus on astrocytes, extracellular vesicles and antibody treatment2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. Being the most numerous glial cell type in the brain, astrocytes are important for many functions, but their role in AD is poorly understood. The aim with this thesis was to clarify the involvement of astrocytes in AD by using a co-culture system of primary neurons and glia. The co-cultures were exposed to soluble amyloid-beta (Aβ) aggregates, i.e. protofibrils that are known to be particularly harmful.

    In Paper I, the capacity of astrocytes to ingest and degrade Aβ protofibrils was investigated. We found that astrocytes effectively ingested Aβ, but were ineffective in degrading the material. The intracellular accumulation of Aβ in astrocytes resulted in lysosomal dysfunction, high intracellular load of partly N-terminally truncated Aβ and extracellular vesicle (EV) mediated neuronal cell death.

    Cells can communicate by releasing cargo into EVs, but the role of EVs in the spreading of Aβ pathology is unclear. In Paper II, the protein content of EVs released specifically following Aβ protofibril exposure was analyzed. We found markedly increased levels of apolipoprotein E (apoE) in EVs from Aβ protofibril exposed co-cultures, suggesting a role for intercellular transfer of apoE in Aβ pathology.

    Passive immunotherapy has been suggested as a promising therapeutic strategy for AD. In Paper III, we investigated if the Aβ protofibril-selective antibody mAb158 could affect Aβ clearance in the co-culture. The mAb158 treatment reduced Aβ accumulation in astrocytes and rescued neurons from Aβ-induced cell death.

    In Paper IV, we explored the effect of EVs, isolated from Aβ protofibril exposed co-cultures on cultured neurons. In addition to increased cell death, we found that such EVs had a strong negative impact on the synapses, dendrites and mitochondria of the neurons.

    Taken together, this thesis contributes with important knowledge about the role of astrocytes in Aβ pathology, the vesicle-mediated spreading of Aβ and the effects of anti-Aβ antibody treatment.

    Abstract [en]

    Background: Despite the clear physical association between activated astrocytes and amyloid-beta (A beta) plaques, the importance of astrocytes and their therapeutic potential in Alzheimer's disease remain elusive. Soluble A beta aggregates, such as protofibrils, have been suggested to be responsible for the widespread neuronal cell death in Alzheimer's disease, but the mechanisms behind this remain unclear. Moreover, ineffective degradation is of great interest when it comes to the development and progression of neurodegeneration. Based on our previous results that astrocytes are extremely slow in degrading phagocytosed material, we hypothesized that astrocytes may be an important player in these processes. Hence, the aim of this study was to clarify the role of astrocytes in clearance, spreading and neuronal toxicity of A beta. Results: To examine the role of astrocytes in A beta pathology, we added A beta protofibrils to a co-culture system of primary neurons and glia. Our data demonstrates that astrocytes rapidly engulf large amounts of A beta protofibrils, but then store, rather than degrade the ingested material. The incomplete digestion results in a high intracellular load of toxic, partly N-terminally truncated A beta and severe lysosomal dysfunction. Moreover, secretion of microvesicles containing N-terminally truncated A beta, induce apoptosis of cortical neurons. Conclusions: Taken together, our results suggest that astrocytes play a central role in the progression of Alzheimer's disease, by accumulating and spreading toxic A beta species.

    Abstract [en]

    Extracellular vesicles (EVs), including exosomes and larger microvesicles, have been implicated to play a role in several conditions, including Alzheimer's disease (AD). Since the EV content mirrors the intracellular environment, it could contribute with important information about ongoing pathological processes and may be a useful source for biomarkers, reflecting the disease progression. The aim of the present study was to analyze the protein content of EVs specifically released from a mixed co-culture of primary astrocytes, neurons, and oligodendrocytes treated with synthetic amyloid-beta (A beta(42)) protofibrils. The EV isolation was performed by ultracentrifugation and validated by transmission electron microscopy. Mass spectrometry analysis of the EV content revealed a total of 807 unique proteins, of which five displayed altered levels in A beta(42) protofibril exposed cultures. The most prominent protein was apolipoprotein E (apoE), and by western blot analysis we could confirm a threefold increase of apoE in EVs from A beta(42) protofibril exposed cells, compared to unexposed cells. Moreover, immunoprecipitation studies demonstrated that apoE was primarily situated inside the EVs, whereas immunocytochemistry indicated that the EVs most likely derived from the astrocytes and the neurons in the culture. The identified A beta-induced sorting of apoE into EVs from cultured neuroglial cells suggests a possible role for intercellular transfer of apoE in AD pathology and encourage future studies to fully elucidate the clinical relevance of this event.

    Migrating IoT Applications to the Fog2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The goal of this thesis is to investigate an IoT cloud application that consists of little Bits (smart electronics gadgets), Philips Hue lamps (smart home lighting system) and cloud service provider IFTTT. IFTTT provides APIs through well known service providers or device manufacturers to interconnect devices and services. The functionality of this application is to perform actions on the Hue lamps based on an input signal from little Bits. This application introduces high latency because of the various involved cloud services that are used to forward the request from little Bits to Philips Hue lamps. Initially we try to detect the source of the high latency and then we migrate the application logic from the cloud down to a fog node on the local network.With this approach all the requests will be fulfilled through the local network so the status and quality of the Internet connection and cloud services will not affect the functionality.

    "Varför får man bara ta beigt papper?": Barns aktörskap i ateljén2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vår studie syftar till att undersöka om barn har möjlighet till eget aktörskap i förskolans ateljé. I vår studie utgår vi från ett barndomssociologiskt perspektiv. Vi betraktar barn som aktiva aktörer då de, utifrån egen förmåga, kan handla och reflektera. Vi ser barn som kompetenta och sociala individer som genom erfarenheter och möjligheter kan utveckla, utnyttja sitt aktörskap i förskolans ateljémiljö. För att uppnå vårt syfte har vi observerat två förskolor för att kunna se om barn har möjlighet till att ta egna initiativ i ateljén. Vi observerade situationer utifrån ett observationsschema där vi kategoriserade barns initiativtagande i möjlighetssituationer där barnet, pedagogen och rummet var viktiga faktorer. Vi observerade även när barnen förhindrades att ta eget initiativ. Vi har också fotograferat delar av ateljén för att med stöd av bilder kunna titta på bland annat åtkomlighet av material för barn. Vi kom fram till att barnen gjorde aktiva val, samt erbjöds möjligheter, för att utöva och utveckla sitt aktörskap. I många situationer har barnens aktörskap visat sig genom att barnen exempelvis fått komma med åsikter och blivit hörda. Där av har de kunnat påverka sin situation i ateljén.

    Kjol eller slips?: En visuell genusanalys av förmänskligade djur i bilderböcker2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att visuellt undersöka om det finns könsroller eller könsstereotyper i bilderböcker med förmänskligade djur. För hjälpa till att undersöka syftet har tre frågeställningar formulerats. Har karaktärerna på bilderna könskodade kläder, färger eller attribut? Om ja, på vilket sätt syns detta i bilderböckerna? Hur kan karaktärernas aktivitet kopplas till könsroller? Hur kan karaktärernas objekt kopplas samman med könsroller?

     

    Metoden som användes är en kvalitativ bildanalys där fyra bilderböcker från åren 1995-2014 granskades och analyserades. Den teori som genomsyrar hela uppsatsen är genusteorin.  Resultatet av studien visade att könsroller och könsstereotyper är ett vanligt förekommande fenomen i böcker med förmänskligade djur. I tre av fyra utav de analyserade böckerna upptäcktes stereotypa könsmönster. De könsmönster som framträdde var en uppdelning mellan könen inom områdena kläder, färger, aktiviteter och artefakter. De böcker som har analyserats i uppsatsen är Bu och Bä i blåsväder, Kottens hemlighet, Familjen Nalle åker bil och Pite och Palt leker kurragömma.

     

    Nyckelord: Genus, könsstereotyper, barnlitteratur, förmänskligade djur.

    "Det är ju inte som att de sitter vid YouTube": En kvalitativ studie av förskollärares professionella självbild i relation till IKT2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med föreliggande uppsats är att undersöka hur en digitaliserad förskola där IKT ingår som både innehåll och metod svarar mot förskollärares professionella självbild. I studien undersöks positioner och förhållningssätt till IKT bland förskollärare. Hur positionerna är sammansatta och attityderna underbyggda undersöks och analyseras. Ambitionen är att ge en så fullödig förståelse som möjligt till synsätt på IKT och därmed också synen på förskolläraruppdraget och den professionella yrkesidentiteten. Studien sätter IKT i ett professionsteoretiskt sammanhang och visar hur IKT kan fungera som statushöjande för förskollärarna samt för att utöka och ringa in yrkets kunskapsbas. De teoretiska utgångspunkterna består i att professioner är föränderliga och utvecklas i växelverkan med samhällsutveckling och historisk kontext. Professionaliseringsstrategier som bottnar i yrkesgruppers sökande efter sin kunskapsbas appliceras på förskolläraryrket och IKT. Här blir också fenomen och begrepp som ontologisk säkerhet relevanta.

    Undersökningens empiri består av fyra intervjuer med examinerade förskollärare med engagemang i och intresse för IKT. Studien är således kvalitativ och ska betraktas som ett nedslag i en typ av verklighet bland många andra.

    Resultatet visar att en uppsättning nyckelkompetenser framträder i relation till IKT bland förskollärarna i studien, som i sin tur analyseras. Kompetensutveckling och fortbildning med avseende på IKT framstår som ett övervägande individuellt projekt för förskollärarna i studien. Det egna ansvaret att adressera eventuella kunskapsluckor som intervjuerna ger vid handen analyseras vidare och framstår som en faktor till de skilda positioner angående IKT bland förskollärare som litteratur i ämnet påvisar existerar. IKT i förskolan och som del i förskollärares professionella självbild ställs också i relation till barnsyn, syn på lärande och syn på förskolans uppdrag. Resultaten visar också att IKT tolkas och förstås i relativ samklang med rådande förskolepedagogiska normer och traditioner för att få större legitimitet i verksamheten.

    "Är det ens någon skillnad?": Tema och projekt i förskolan och barns inflytande över arbetssätten2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I förskolan används olika arbetssätt som gynnar barns lärande och skapar trygga individer. Två arbetssätt som vi har erfarit under våra VFU-tillfällen (verksamhetsförlagd utbildning) är tema och projekt. Tema är flera aktiviteter med en röd tråd och projekt är målinriktade aktiviteter skapade utifrån barns intressen. Det finns ett begränsat utbud av vetenskapliga artiklar gällande tema och projekt. Vi beslöt oss för att intervjua förskollärare kring deras tidigare upplevelser och erfarenheter om begreppen. Vi redogör för hur barn upplever tema och projekt samt om de upplever att de har ett inflytande över arbetssättet som används i respektive verksamhet. I Läroplan för förskolan står det att barn ska utveckla förmågan att utöva inflytande i verksamheten och få känna att deras åsikt räknas (Lpfö98, rev. 2016, s.12). Vi kommer därför att använda metoden barnintervjuer för att få en insyn i om barn upplever att de har inflytande i verksamhetens arbetssätt eller inte.

    Vi vill tydliggöra begreppens innebörd med hjälp av erfarna förskollärare som arbetat med dessa arbetssätt i verksamheten. Våra tidigare erfarenheter har visat att barn får olika mycket bestämmanderätt över arbetssätten beroende på förskola. Tema och projekt får enligt oss stort utrymme i verksamheten och under vår utbildning har vi fått kunskap om hur viktigt det är för barn att få inflytande i förskolans planerade aktiviteter. Därför har vi valt att undersöka barns inflytande i arbetssätten. Barns inflytande på verksamheten kan differentiera sig mellan förskolor på grund av att läroplanen är tolkningsbar. I läroplanen visas det vilka strävansmål förskolan ska arbeta mot men det framgår inte hur förskollärarna ska arbeta för att nå målen. Genom arbetet hoppas vi kunna ge en bättre förståelse över hur de olika arbetssätten ser ut samt huruvida barns inflytande tas till vara när man arbetar med arbetssätten.

    The successor of the Prophet: A historical analysis of the early political differences between the Sunni and Shi’a Islamic school of thoughts.2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The early split of Islam is regarded as one of the most profound and complex events in Islamic history, not only would it lay the foundation of two predominant branches of Islam, but it would also be one of the oldest arguments in Islamic history. Who is the rightful successor to the Prophet Muhammed? This essay aims to explore the deep root behind the initial schism of Islam and understand the arguments both schools use to legitimize their position. What do the Sunnis and Shi’as say about the event of Ghadir, the hadith of the two weighty things and the incident of Saqifa, and how do each school of Islam interpret these events? The source material consists of Hadiths and scholastic literatures from both Sunni Islam, Shi’a Islam, as well as literatures from Secular sources. By basing the analysis on Wilfred Madelung’s and Ali Asghar’s theory of disserting Orientalist understanding of a monolith perspective on Islamic history, the essay aims to understand and broaden the reality of the schism of Islam and to bring emphasis on the events that often goes ignored throughout history. Finally, the results prove that both Sunnis and Shi’as differ regarding the caliphate, and the assertions for these lay in their respective interpretations. The Shi’as maintain that Ali should’ve been the successor, while the Sunnis believe Abu Bakr was the caliph.

    Kom och köp min tro!: En religionssociologisk studie om Svenska kyrkans utbud i sociala medier.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study has examined the content of the Swedish Church's posts on the social network media Facebook and Instagram. The posts were published during September to November 2017, which is about 90 posts. I have also analysed if the posts could be seen as marketing in this particular media form. Rational Choice Theory has served as an overall theory in which I assumed that people make rational decisions in the choosing of their religion. Therefore, I see the content on these sites as a supply of the Swedish church religiosity that people can base their decisions on. Through an inductive approach, themes have been searched for in the posts and analysed through text condensation. The result of the study is that there are six types of published content, grief management, church operation, divinity, entertainment, religious history and informative posts about the Swedish church election that took place in September 2017.

    These posts can be seen as marketing because the focus in marketing has shifted from emphasis on the product to the consumer. The purpose is now to provide consumers with information that they can base their decisions on. Therefore, when people use the information on these sites in order to make a rational choice of their religion, the post can be seen as marketing of the Swedish Church, but not in cases when people read the post in other purposes.

    Pronoun translation between English and Icelandic2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A problem in machine translation is how to handle pronouns since languages use these differently, for example, in anaphoric reference. This essay examines what happens to the English third person pronouns he, she, and it when translated into Icelandic. Parallel corpora were prepared by tokenisation and subsequently the machine translation method word alignment was applied on the corpus. The results show that when a pronoun is used to refer to something outside the sentence (extra-sentential), this gives rise to major problems. Another problem encountered was the differences in the deictic strength between pronouns in English and Icelandic. One conclusion that can be drawn is that more research is needed as more reliable ways of handling pronouns are needed in translations.

    Visualizing Important Areas for Facial Verification A Deep Learning Evaluation with ArtificialNoise Injection2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Facial verification is a growing area of research, where heavily trained neural network models obtain superhuman performance on recognizing individuals. However, because of network models' complex nature, it is hard to know what areas of the image are used. This thesis introduces three visualization techniques, to better understand the importance of different facial areas when performing verification. A method for measuring the visualizations' hierarchical correctness was established, evaluating the model's ability to preserve and damage the verification performance, when treated as artificial pixel noise. This is done for two types of networks, which are different in their architecture and their input dimensionality (one taking full color and the other taking grayscale images).

    Implementation and Simulation Study of Methods for the Evolution of Interdependent Networks2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this work is to study different methods for the evolution of interdependent networks. Different systems such as social networks, proteininteractions or transportation systems can be represented using multilayer networks, which can provide a simple and unified means of expression. In this work,we start by selecting a representation of multilayer networks and outlining the pre-existingmethods to simulate their evolution. We then propose a model of multilayer network formation that considers target measure for the network to be generated and focuses on the case of finite multiplex networks. Thus, before defining the model we propose different measures and properties that should enable us to differentiate between a generated network and a real life counterpart. We simulate network formation following the previous method and show in which cases we get closer to our target measures.

    Job Scheduling Using Neural Network in Environment Inspection2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Environment inspection is becoming more and more important now. Many qualified institutes provide professional inspecting services for general companies. One problem with environment inspection is that the number of equipment in the institute is limited compared to the number of projects. A hybrid scheduler designed for the problem of environment inspection job scheduling. It uses tabu search techniques and embeds neural network in the scheduler. After training the neural network, the hybrid scheduler uses trained network to narrow the search range of the tabu search which makes the scheduler faster. The comparison between tabu search scheduler and hybrid scheduler indicates that the latter runs much faster.

    Background: Shift work is common in today’s society. About 75% of shift workers have problems regarding sleep and recovery. Research has investigated shift worker’s physical and psychological problems connected to poor sleep, sleep disorders and insomnia. However, little research has been made concerning prevention and treatment of negative consequences of working in shifts.

    Purpose: The aim of the study was to examine if there are health promoting actions that can be offered by nurses to preserve sleep quality and improve recovery in shift workers and if there is evidence if any of the actions is superior.

    Method: A literature review was conducted through a search for scientific original articles in PubMed and Cinahl. Twelve articles were included in the study.

    Results: Cognitive behavioral therapy and sleep health program can reduce symptoms of anxiety, reduce depression and increase the feeling of being well rested. Napping during night shift improved reactivity and reduced feelings of fatigue and increased recovery of function. Light therapy and treatment with melatonin had a moderate effect on alertness and a small effect on quality of sleep. Light therapy had effect regarding insomnia, depression and anxiety. Treatment with the drug Armodafinil resulted prolonged sleep, improvement in wakefulness and reduced fatigue. Armodafinil treatment was also associated with improved well-being, memory and attention.

    Conclusion: Options are available for treatment of physical psychological symptoms related to shift worker, but require interaction between healthcare and employers. More research is needed regarding non-pharmacological treatments suitable for a nurse interventions in primary and occupational care. The result of this study shows that treatment with Armodafinil gave the best effects.

    Värmekamera i fysikundervisning: En undersökning av hur värmekameran kan stimulera inlärningen av värmerelaterade fenomen2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Thermodynamics is often perceived as an abstract field in secondary school physics. Thermodynamics can thus be a tough challenge for many students. By including thermal imaging cameras in teaching, students are given the opportunity to see otherwise invisible thermal phenomena. Since the infrared camera has not yet been established in teaching, there is an interest in studying the interaction between students and the thermal imaging camera. The purpose of this study is to investigate the interaction between student and the infrared camera and to see how the infrared camera can help students in the conceptual formation of heat-related phenomena. The study included about 140 students attending their first year on the science program at an upper secondary school in central Sweden. The students had to perform laboratory experiments designed according to the prediction-observation-explanation method. The laboratory experiments consisted of three stations where the key concepts were heat conduction, collision and friction. Students took help of an infrared camera to explain the various phenomena. The students' interactions at the lab were documented with video and audio recording in order to set the basis of a qualitative analysis. The analysis of the material consisted of three parts: how students reason concerning heat conduction, their reasoning concerning dissipative processes as friction and collision, and how the infrared camera can stimulate the students' creative thinking. Many student groups were successful in the macroscopic and quite successful in the microscopic reasoning regarding heat conduction by applying a model of free electrons in the metal which they had learned in chemistry class. Other studies have shown that students find it hard explaining heat conduction and that they tend to interpret the physical touch as a thermometer. The group that examined friction and collision found it difficult explaining the transformation from kinetic energy into thermal energy in collision at both the macroscopic and microscopic level. The creative investigation resulted in a mess. The infrared camera attracts students' curiosity, gives ”disciplinary affordance” and stimulates them to ”instant inquiry”. When the students went beyond their instructions and conducted own investigations it resulted in a mess when they prioritized away the recently created hypotheses.

    Strengthened General Self-Efficacy with Multidisciplinary Vocational Rehabilitation in Women on Long-Term Sick Leave: A Randomised Controlled Trial2018In: Journal of occupational rehabilitation, ISSN 1053-0487, E-ISSN 1573-3688Article in journal (Refereed)
    Abstract [en]

    Purpose To investigate the effects of two vocational rehabilitation interventions on self-efficacy, for women on long-term sick leave ≥ 1 year due to chronic pain and/or mental illness. Methods This study uses data from a randomised controlled trial consisting of two phases and comprising 401 women on long-term sick leave. They were allocated to either (1) a multidisciplinary team assessment and multimodal intervention (TEAM), (2) acceptance and commitment therapy (ACT), or (3) control group. Data were collected through repeated measurements from self-reported questionnaires before intervention, 6 and 12 months later and registry data. Data from measurements of general self-efficacy, sociodemographics, anxiety and depression were analysed with linear regression analyses. Results During the intervention period, the women in the TEAM group’s self-efficacy mean increased from 2.29 to 2.74. The adjusted linear regression model, which included group allocation, sociodemographics, self-efficacy pre-treatment, anxiety and depression showed increased self-efficacy for those in the TEAM intervention at 12 months (B = 0.25, 95% CI 0.10–0.41). ACT intervention had no effect on self-efficacy at 12 months (B = 0.02, 95% CI − 0.16 to 0.19). The results in the adjusted model also showed that higher self-efficacy at pre-treatment was associated with a higher level of self-efficacy at 12 months (B = 0.68, 95% CI 0.54–0.81). Conclusion A multidisciplinary team assessment and multimodal intervention increased self-efficacy in women on sick leave for an extremely long time (mean 7.8 years) who had a low mean level of self-efficacy prior to inclusion. Thus, self-efficacy needs to be addressed in vocational rehabilitation.
