    Climate-induced changes: Its effects on plankton food webs from the Baltic Sea2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The Earth’s climate is determined different processes occurring in the atmosphere, land and ocean.Anthropogenic activities (mainly combustion of fossil fuels) have increased since the 1950’s, andthus the concentration of greenhouse gases that are warming up the planet. Such events have andwill likely continue to have profound impact on ocean biological processes directly affecting thephysiology of marine organisms and population dynamics.This thesis deals with the effects of climate-induced changes in seawater temperature and pH(acidification) on the development and structure of Baltic Sea plankton communities. Mesocosmexperiments were set up to expose both spring and summer Baltic Sea plankton communities totemperature and pH levels predicted by the year 2100, both isolated and in combination.Experiments lasted for 20 and 12 experimental days, for spring and summer seasons, respectively.Parameters analyzed were phytoplankton biomass (Chlorophyll a) and growth rates (Chlorophyll aaccumulation) and phytoplankton, microzooplankton (ciliates and heterotrophic nanoflagellates),mesozooplankton (copepods) and bacteriae densities. The obtained results were later compared(ANOVA test) and diversity indexes were calculated for phytoplankton, ciliate and totalcommunities. Cluster analyses were done based on species/groups composition of the planktoncommunities.The highest phytoplankton (chlorophyll a) and total plankton (Particulate organic carbon-POC)biomass were found during both experiments in the higher temperature treatments. During spring,the phytoplankton biomass found in the present conditions treatment on the last day experimentalwas achieved 3 days earlier in the higher temperature treatmtents. Thus the peak of the springbloom was accelerated by c. 1 day °C-1. Lower pH treatments increased phytoplankton biomassabove the present conditions in the spring, but did not in summer. However, higher POC wereobserved in the lower pH treatment during both spring and summer. During the spring, thecombination of lower pH and higher temperature had a greater impact on the natural planktoncommunities than each isolated factor. Spring phytoplankton communities were initiallydominated by the diatom Skeletonema costatum, while in the summer cyanobacteriae dominated(although in both cases in very low densities). In the lower pH-higher temperature treatment fromthe spring, the phytoplankton community shifted and haptophytes and dinoflagellates becamemore representative, whereas in summer potentially toxic, filamentous cyanobacteriae (includingharmful, bloom-forming Nodularia spumigena) increased in numbers.In the lower pH and high temperature treatments of the spring experiment and in all treatments ofthe summer experiment, decreases in ciliate and nanoflagellate densities were correlated to highcopepod densities. Although the phytoplankton biomass was favored by higher temperature andacidification, a slight decrease of diatoms and a shift towards a community dominated by smallsized species was observed during both experiments. Predicted changes in seawater temperatureand pH will result in more carbon being incorporated into the planktonic food webs of the BalticSea, both in spring and summer, with shifts in species composition that will likely change thecarbon pathways. Further studies are needed to clarify the transfer efficiency of the incorporatedcarbon to higher trophic levels, and the resulting net productivity of the system in face of the new conditions.

    Där berättelsen äger rum: Narration, perception och kognition i ett kombinerat text- och läsarperspektiv med exempel ur Eyvind Johnsons författarskap2010Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [sv]

    I en narratologisk studie granskas spatialitet i skönlitterär prosatext. I texten undersöks några spatiala nivåer som kan länkas till extradiegetisk berättarinstans och "normal" perception kontra drömmar och visioner hos karaktärer inom diegesen. Till den narratologiska studien kopplas undersökningsmodeller hämtade från det som med en paraplyterm kallas kognitiv poetik och som behandlar både den litterära texten och läsarens perception och kognition i läsprocessen. I studien berörs också den fiktiva berättelsen betraktad som "värld" ur ett litteraturteoretiskt och filosofiskt resonemang kring begreppen "actual world", "possible worlds" och "fictional worlds".  Det övergripande syftet är att förklara hur text och läsarkognition samspelar för att skapa mentala, rumsliga "bilder" hos läsaren, bilder som kan skifta mellan olika läsare och som resulterar i den berättelsens "värld" som läsaren upplever. Som grundtexter i avhandlingsarbetet används Eyvind Johnsons Krilonsvit.

    Etnicitet, ungdom och socialt arbete: En analys av kulturbegreppet i ett komplext och kluvet forskningsfält2010Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The aim of this thesis is to present, describe, and analyze scientific and official Swedish discourses that deal with social work with ethnic minority youth. The empirical analysis is built on an analysis of different texts such as scientific articles, public reports, teaching materials from 1960-2005 about social work with ethnic minority youth and describes the development of different perspectives on ethnicity and culture that have dominated social work debates. A very common and popular discourse both in research and in official contexts is that social problems are explained by cultural background when it comes to ethnic minority youth whereas the same problem among young people with “Swedish” background is explained by social or psychological aspects. This is an analytical framework that has been dominant in social work discourse from the 1960s forward, yet which is seldom explored and problematized in empirical studies. One of the main findings/arguments is that culture is an important key term used in both ”constructing”, explaining, and solving social problems in relation to ethnic minority youth. The most dominant theoretical approach in discussions of ethnic minority youth’s identity formations is a culturalist perspective often referred to as “the second generation problem”. This is a perspective that is built on an essential and static understanding of culture and a theoretical approach I call the cultural distance logic. Another finding in the material analyzed is that different questions are focused on and explained differently during different time periods. Further, this also means that methods and suggestions with how to develop social work with people with minority background, has also changed during the time period studied.

    The texts analyzed are contextualized in relation to debates and politics over immigration. For example, in the early 1960 an evolutionary understanding of culture dominated (with Swedish culture as modern and desired) and assimilation was proposed as an ideal. Whereas during the 1970s a more multiculturalists and in many ways more egalitarian understanding of culture dominated and social workers focused on ways to help children with ethnic minority background keep contact with their culture of origin. One of the outcomes of this perspective in the texts analyzed is that people/youth with ethnic minority background were now described as a representation of a nation and the method of ‘cultural competence’ was equated with solely having an ethnic minority background. Later on, in the 1980s- 1990s culture again becomes something problematic and connected to lack of adaption. During this time we can see how social problems are understood within the framework of there being ‘big differences’ between “Swedes” and “immigrants”, and that these factors are central in explaining social problems.

    In the 1990s the relevance of culture has been questioned and a big theoretical controversy can in recent years be seen in how to discuss ethnic minority youth and social work. Are social problems to be explained by culture only or is it the structures in society, such as socio-economic inequalities and discrimination? These debates are “old” but now crystallized in the discussion of honor related violence. This is a discussion that places the immigrant family in problematic light and they are portrayed sometimes as a salvation and sometimes the destroyer of the possibility for young people with ethnic minority background to become “real Swedes”.

    Keywords: young people with ethnic minority background, social work, culture, ethnicity, discrimination.

    Handledning för vårdare - ett lärande möte utifrån patientens värld2010Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The present research study is a supervision project which was carried out between 2004-2006.  The overall aim of the research was to investigate how caring science supervision can support carers in integrating caring science and can contribute to a constructive way of integrating caring science knowledge with praxis.

    The research project consisted of supervision given to groups of carers in two different contexts where a caring science model for supervision was tested and developed.

    The experience of how carers integrate caring science knowledge through supervision has been studied by interviewing carers. Seven were interviewed in the first study about how they experienced their own learning process by participating in group supervision. The second study focused on how the supervisor’s selection of different supervision methods can support the carers’ development and understanding for the patient’s lifeworld.

    The interviews were analysed with the help of a reflective lifeworld approach. The results from the seven interviews consisted of a description of the essence and seven constituents. The results show that knowledge about caring, from the carers’ point of view, is an attitude that is taken for granted. With this as a starting point the carers listen and read what has happened to the patient in different situations. In the supervision session the carer and the supervisor have worked out a critical caring science investigation of the patient’s situation and developed new strategies for the patient’s caring. The interviewed carers point out the importance of a free zone, a learning room in supervision, where they can reflect and, in a constructive dialogue with each other, work with the patient’s situation together with the supervisor.

    In the second research study the supervisor’s selection of methods in supervision is in focus. The aim of using these different methods was to support the development of knowledge grounded in caring science. The supervision methods support the carers in the reflection process and stimulate them to develop good skills in the relationship with the patient.  The results also show, in two ways, how important the supervisor’s role is for the supervision process. Firstly in terms of being able to see and understand what the focus is in the carer’s narrative of the patient’s situation.  Secondly how the selection of an appropriate method can support the carers’ understanding of what obstacles there can be and which possibilities there can be for the caring of the patients. This work in the supervision process demands that supervisors are aware of how the group process can be integrated with the learning process.

    Keywords: caring science, phenomenology, lifeworld, reflection, dialogue, supervision, supervision methods.

    Ion exchange processes on float glass surfaces2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Glass can be strengthened by ion exchange and this process is presently used inspecial applications e.g. aircraft windshields, displays and spectacle lenses allowinga higher production cost. Chemically strengthened float glass is moreexpensive than thermally strengthenened, but will likely find applications in futurebuilding and interior constructions where strength demands, design andshape prevent the use of thermal strengthening. The aim of this work is tostudy ion exchange on float glass surfaces. In longer terms, the chemicalstrengthening is planned to be applied to specific critical area e.g. around adrilled hole which without treatment deteriorates the overall strength of theglass.Strengthening the glass through ion exchange can be done in several ways butis most often referred to as the replacement of smaller ions in the glass structureby larger ions from the salt used for treatment. By determining concentrationvs. depth profiles of ion exchanged float glasses, it is possible to calculate thediffusion coefficients and activation energy for different ions. In this study, theless frequently studied approach single-side ion exchange of different ions ofcommercial float glass is described. The concentration vs. depth profiles weredetermined either by the use of the Surface Ablation Cell (SAC), which allowsthe continuous removal of the material from a flat glass surface by slow controlledisotropic dissolution or SEM-EDX.The results of the work are that similar diffusivities and concentration vs. depthprofiles are achieved with single-side ion exchange as from the traditional wayof immersing glass in molten salt bath. Ion exchange of Ag+ stains the floatglass on both sides giving it a yellow or amber-brownish colour. Unlike Ag+ ionexchange of Cu+ stains the float glass on the tin-side only, giving it a yellow,red or red-brown colour. Determining the concentration vs. depth profiles ofion exchanged float glasses with the SAC was convenient except for Ag+ whichwas determined with SEM-EDX. The work confirms that the procedure andequipment of the SAC are very cheap, easy to use and gives data similar tothose gained by much more expensive equipment. Calculated diffusion coefficientsof K+, Ag+ and Rb+ are in accordance with literature data while Cu+ and Cs+ diffusion coefficients were slightly lower. The diffusion coefficients of the different ions follow the order Ag+>K+>Cu+>Rb+>Cs+ and ranges between9.4E-10 and 4.8E-13 cm2s-1. The calculated activation energies for diffusion of K+, Ag+ and Cu+ corresponds with reported literature data and were calculated to: Ag+(air-side) 152 kJ/mol, Ag+(tin-side) 185 kJ/mol, K+ 108 kJ/mol and Cu+115 kJ/mol.

    Klungan och barndomens sociala rum: Socialt gränsarbete och figurationer i rastfotbollen2010Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [sv]

    Denna licentiatavhandling, Klungan och barndomens sociala rum, diskuterar den samtida heterogena barndomen utifrån analyser av barns informella fotbollsspel på rasten i skolan. Det empiriska exemplet rastfotboll analyseras med begrepp som rum, genus och gränsöverskridande. Rumsanalys av rastfotbollen ger exempel på hur traditionella könshierarkier reproduceras, omformas och utmanas i löst organiserade former av idrott. Perspektiven i studien hämtas från barndomssociologi, idrottsvetenskap, kulturgeografi, filosofi och genusforskning. Barndomens komplexitet skapas av att logiker från olika sociala rum – t.ex. familj, skola och idrott – samexisterar och motsägs. Det tvärvetenskapliga angreppssättet och tillhörigheten till det flerdisciplinära forskningsprojektet Mångkontextuell barndom gör studien till ett exempel på det den avser att beskriva: gränsöverskridanden och flöden i en heterogen verklighet.

    Nelson-type Limits for α-Stable Lévy Processes2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Brownian motion has met growing interest in mathematics, physics and particularly in finance since it was introduced in the beginning of the twentieth century. Stochastic processes generalizing Brownian motion have influenced many research fields theoretically and practically. Moreover, along with more refined techniques in measure theory and functional analysis more stochastic processes were constructed and studied. Lévy processes, with Brownian motionas a special case, have been of major interest in the recent decades. In addition, Lévy processes include a number of other important processes as special cases like Poisson processes and subordinators. They are also related to stable processes.

    In this thesis we generalize a result by S. Chandrasekhar [2] and Edward Nelson who gave a detailed proof of this result in his book in 1967 [12]. In Nelson’s first result standard Ornstein-Uhlenbeck processes are studied. Physically this describes free particles performing a random and irregular movement in water caused by collisions with the water molecules. In a further step he introduces a nonlinear drift in the position variable, i.e. he studies the case when these particles are exposed to an external field of force in physical terms.

    In this report, we aim to generalize the result of Edward Nelson to the case of α-stable Lévy processes. In other words we replace the driving noise of a standard Ornstein-Uhlenbeck process by an α-stable Lévy noise and introduce a scaling parameter uniformly in front of all vector fields in the cotangent space, even in front of the noise. This corresponds to time being sent to infinity. With Chandrasekhar’s and Nelson’s choice of the diffusion constant the stationary state of the velocity process (which is approached as time tends to infinity) is the Boltzmann distribution of statistical mechanics.The scaling limits we obtain in the absence and presence of a nonlinear drift term by using the scaling property of the characteristic functions and time change, can be extended to other types of processes rather than α-stable Lévy processes.

    In future, we will consider to generalize this one dimensional result to Euclidean space of arbitrary finite dimension. A challenging task is to consider the geodesic flow on the cotangent bundle of a Riemannian manifold with scaled drift and scaled Lévy noise. Geometrically the Ornstein-Uhlenbeck process is defined on the tangent bundle of the real line and the driving Lévy noise is defined on the cotangent space.

    Promoting Semantic Interoperability of Contextual Metadata for Learner Generated Digital Content2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Technological advancements in computing have led to a reality where computational devices are more mobile, connected and context aware than ever before. Several of these devices are primarily designed for or support the creation of digital content via built-in or attachable sensors, e.g. mobile phones. The portability and connectivity of mobile devices make them suitable tools to support learning experiences; their features can be used to generate digital content and metadata related to the particular learning situation. These types of objects, referred to as Emerging Learning Objects (ELOs), introduce challenges in terms of metadata enrichment as their metadata should reflect aspects related to the particular learning situation in which they were created to be properly indexed. A claim made in this thesis is that semantic interoperability of ELO metadata is an integral concern that needs to be explored in order to benefit from these metadata outside custom tailored applications and systems. Therefore, the main research question explored in this thesis focuses on the ability to enrich ELOs with semantically interoperable contextual metadata.

    This thesis is comprised of a collection of five peer-reviewed articles that describe interrelated stages of research in pursuit of an answer to the main research question. The overall research process consisted of three main stages: a literature review; the development a system artefact; and the exploration of the technological solution (Linked Data) applied in the system artefact. An instantiation of the Unified Process guided the development of the system artefact.

    The outcomes of these activities provide insights on how to perceive the relationship between context and contextual metadata, as well as properties related to a particular technological solution, namely data distribution, flexibility and expressivity. In order to decouple the findings from a particular instance of technology, a generalization effort in the analysis identified two generic factors that affect the semantic interoperability of metadata: the level of ontological consensus and the level of metadata expressivity. The main conclusion of this thesis is that until the constituent parts of context are agreed upon, metadata expressivity is an important feature for promoting semantic interoperability of ELO contextual metadata.Technological advancements in computing have led to a reality where computational devices are more mobile, connected and context aware than ever before.

    Propagation of singularities for pseudo-differential operators and generalized Schrödinger propagators2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    I denna avhandling diskuterar vi olika typer av regularitet för distributioner som uppkommer i teorin för pseudodifferentialoperatorer och partiella differentialekvationer. Partiella differentialekvationer förekommer inom naturvetenskap och teknik. Exempelvis kan Schrödingerekvationen användas för att beskriva förändringen med tiden av kvanttillstånd i fysikaliska system. Pseudodifferentialoperatorer kan användas för att lösa partiella differential\-ekvationer. De användas också för att modellera olika typer av problem inom fysik och teknik. Det finns till exempel en naturlig koppling mellan pseudodifferentialoperatorer och stationära och icke-stationära filter i signalbehandling. Vidare gäller att relationen mellan symboler och operatorer vid övergången från klassisk mekanik till kvantmekanik i huvudsak överensstämmer med symboler och operatorer inom Weylkalkylen för pseudodifferentialoperatorer.

    I den här avhandlingen koncentrerar vi oss på att undersöka hur regularitetsegenskaper för lösningar till partiella differentialekvationer påverkas under verkan av pseudodifferentialoperatorer, och speciellt för de fria tidsberoende Schrödingeroperatorerna.

    Lösningen av den fria tidsberoende Schrödingerekvationen kan uttryckas som en pseudodifferentialoperator, med icke-slät symbol, verkande på begynnelsevillkoret. Vi generaliserar ett resultat om icke-tangentiell konvergens av Sjögren och Sjölin (1989) för den fria tidsberoende Schrödingerekvationen.

    Ett annat sätt att beskriva regularitet hos en distribution är med hjälp av vågfrontsmängder. De beskriver inte bara var singulariteterna finns, utan också i vilka riktningar dessa singulariteter förekommer. De första typerna av vågfrontsmängder (analytiska vågfrontsmängder) introducerades av Sato (1969, 1970). Senare introducerade Hörmander ''klassiska'' vågfrontsmängder (med avseende på släthet) och visade resultat för verkan av pseudodifferentialoperatorer med släta symboler, se  Hörmander (1985).

    I denna avhandling betraktar vi vågfrontsmängder med avseende på Fourier Banach funktionsrum. Detta kan ses som att vi låter B vara ett Banachrum, som är invariant under translationer och är inbäddat mellan rummet av Schwartzfunktioner och rummet av tempererade distributioner. Vågfrontsmängden av en distribution innehåller alla punkter (x0, ξ0) så att ingen lokalisering av distributionen kring x0, tillhör FB i riktningen ξ0. Vi visar att pseudodifferentialoperatorer med släta symboler krymper vågfrontsmängden och vi får motsatta inbäddningar med hjälp mängder av karakteristiska punkter till operatorernas symboler.

    Regularization of Parameter Problems for Dynamic Beam Models2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The field of inverse problems is an area in applied mathematics that is of great importance in several scientific and industrial applications. Since an inverse problem is typically founded on non-linear and ill-posed models it is a very difficult problem to solve. To find a regularized solution it is crucial to have a priori information about the solution. Therefore, general theories are not sufficient considering new applications.

    In this thesis we consider the inverse problem to determine the beam bending stiffness from measurements of the transverse dynamic displacement. Of special interest is to localize parts with reduced bending stiffness. Driven by requirements in the wood-industry it is not enough considering time-efficient algorithms, the models must also be adapted to manage extremely short calculation times.

    For the developing of efficient methods inverse problems based on the fourth order Euler-Bernoulli beam equation and the second order string equation are studied. Important results are the transformation of a nonlinear regularization problem to a linear one and a convex procedure for finding parts with reduced bending stiffness.

    SPEED and TIME in the event modifier lexemes slow, fast and quick: A cognitive perspective2010Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    In this thesis I examine the event modifier lexemes slow, fast and quick and the events they modify. A number of observations made of the use of these modifiers cannot be explained by existing event typologies. Instead I propose a model for event structure and construal, in which I define events according to their temporal configuration in terms of DURATIVITY, BOUNDEDNESS and CHANGE. By applying this model to examples of contemporary British English, I show that there are distinct usage patterns for each modifier with regard to the temporal configuration of the events they modify. I further demonstrate that the readings of SPEED and TIME which result from the combination of event and modifier depend on a number of factors, and in doing so provide an insight into the complex conceptual nature of SPEED and its relation to TIME. In the course of the analysis, several other factors, such as the position of the modifier, the function of the -ly suffix, and the adverbal/adjectival status of the modifier are brought to light.

    Keywords: SPEED, TIME, BOUNDEDNESS, CHANGE, events, event modifiers, dual-form adverbs, configurational structure, temporal configuration, construal.

    Systems Dependability Engineering for Wind Power Applications: Challenges, Concepts, and System-Level Methodologies2010Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Complexity and uncertainty have impacted wind power systems and their applications.Commercial wind power asset exhibits complex system behaviour due tostochastic loading characteristics of its installation context. However, differentstakeholders’ practices in whole life cycle processes try to treat multi-disciplinarycomplexity issues. Moreover, wind power system failures, stoppages, faults, supportdelays and human/organizational errors provide a clear proof of increasingthe needs for dependability. Therefore, dependability is considered as an aggregatetheory for RAMS (Reliability, Availability, Maintainability, Safety & Supportability)in order to cope with complex systems (i.e. physical systems and their assetmanagement systems) and their behaviour phenomenon. Consequently, to addresswind power practical problem as one of the modern complex and interdependentsystems, it is worth to enhance both the way of how we look at dependability andthe method of inquiry. Technical system complexity, system interdependency andsystem learn-ability are the main challenges within system dependability field.Therefore, this research work is done to integrate both terotechnology and systemsengineering methodologies to enhance systems dependability theory and practices.In particular, it focuses on three main aspects within systems dependability engineering:challenges, practitioners’ concepts and system-level methodologies.The research methodology of this thesis has utilised the mixed research approachof qualitative and quantitative methods to extract the empirical findings that arerequired to validate the dependability theory developments. Qualitative survey isused to identify the challenges of dependability theory within wind power applications.Grounded theory is used to define the practical understanding of windpower stakeholders concerning to dependability and asset management concepts.Case study is implemented to validate the systems dependability engineering, ascross edge theory of dependability and systems engineering. Moreover, the phenomenographymethod is used to capture the individual experiences and understandingof purposefully selected stakeholders, due to different site-specific circumstancesfor each wind farm.In general, the thesis contributes to the body of knowledge of five fields: dependability,terotechnology, asset management, systems engineering and wind energy.In particular, the focus of thesis contributes with retrospective review to be as referenceline for system dependability theory. Simultaneously, on basis of empiricalfindings, it contributes to be a pivot point for further enhancements from both theacademic contributions and industrial developments.

    Towards a Gold Standard for Points-to Analysis2010Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Points-to analysis is a static program analysis that computes reference informationfor a given input program. It serves as input to many client applicationsin optimizing compilers and software engineering tools. Unfortunately, the Gold Standard – i.e., the exact reference information for a given program– is impossible to compute automatically for all but trivial cases, and thus, little can been said about the accuracy of points-to analysis.

    This thesis aims at paving the way towards a Gold Standard for points-to analysis. For this, we discuss theoretical implications and practical challenges that occur when comparing results obtained by different points-to analyses. We also show ways to improve points-to analysis by different means, e.g., combining different analysis implementations, and a novel approach to path sensitivity.

    We support our theories with a number of experiments.
