    Solitons in a 𝒫𝒯-symmetric 𝜒(2) coupler2017In: Optics Letters, ISSN 0146-9592, E-ISSN 1539-4794, Vol. 42, no 20, p. 4079-4082Article in journal (Refereed)
    Abstract [en]

    We consider the existence and stability of solitons in a 𝜒(2) coupler. Both the fundamental and second harmonics (SHs) undergo gain in one of the coupler cores and are absorbed in the other one. The gain and loss are balanced, creating a parity-time (𝒫𝒯) symmetric configuration. We present two types of families of 𝒫𝒯-symmetric solitons having equal and different profiles of the fundamental and SHs. It is shown that the gain and loss can stabilize solitons. The interaction of stable solitons is shown. In the cascading limit, the model is reduced to the 𝒫𝒯-symmetric coupler with effective Kerr-type nonlinearity and the balanced nonlinear gain and loss.

    An exact lower energy bound for the infinite square well potential2011In: European journal of physics, ISSN 0143-0807, E-ISSN 1361-6404, Vol. 32, no 2, p. L3-L6Article in journal (Refereed)
    Abstract [en]

    We give a lower bound for the energy of a quantum particle in the infinite square well. We show that the bound is exact and identify the well-known element that fulfils the equality. Our approach is not directly dependent on the Schrödinger equation and illustrates an example where the wavefunction is obtained directly by energy minimization. The derivation presented can serve as an example of a variational method in an undergraduate level university course in quantum mechanics.

    On the dynamics of the Fermi-Bose model2013In: Journal of Physics A: Mathematical and Theoretical, ISSN 1751-8113, E-ISSN 1751-8121, Vol. 46, no 1, article id 015005Article in journal (Refereed)
    Abstract [en]

    We consider the exponential matrix representing the dynamics of the Fermi-Bose model in an undepleted bosonic field approximation. A recent application of this model is molecular dimers dissociating into its atomic compounds. The problem is solved in D spatial dimensions by dividing the system matrix into blocks with generalizations of Hankel matrices, here referred to as D-block-Hankel matrices. The method is practically useful for treating large systems, i.e. dense computational grids or higher spatial dimensions, either on a single standard computer or a cluster. In particular the results can be used for studies of three-dimensional physical systems of arbitrary geometry. We illustrate the generality of our approach by giving numerical results for the dynamics of Glauber type atomic pair correlation functions for a non-isotropic three-dimensional harmonically trapped molecular Bose-Einstein condensate.

    Supershell structures and pairing in ultracold trapped Fermi gases2007In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 76, no 2, article id 021601Article in journal (Refereed)
    Abstract [en]

    We calculate level densities and pairing gaps for an ultracold dilute gas of fermionic atoms in harmonic traps under the influence of mean field and anharmonic quartic trap potentials. Supershell nodes, which were found in Hartree-Fock calculations, are calculated analytically within periodic orbit theory as well as from WKB calculations. For attractive interactions, the underlying level densities are crucial for pairing and supershell structures in gaps are predicted.

    Persistent currents in a Bose-Einstein condensate in the presence of disorder2007In: Journal of Low Temperature Physics, ISSN 0022-2291, E-ISSN 1573-7357, Vol. 149, no 3-4, p. 176-184Article in journal (Refereed)
    Abstract [en]

    We examine bosonic atoms that are confined in a toroidal, quasi-one-dimensional trap, subjected to a random potential. The resulting inhomogeneous atomic density is smoothened for sufficiently strong, repulsive interatomic interactions. Statistical analysis of our simulations show that the gas supports persistent currents, which become more fragile due to the disorder.

    Stability of persistent currents in a Bose-Einstein condensate confined in a toroidal trap2009In: Journal of Low Temperature Physics, ISSN 0022-2291, E-ISSN 1573-7357, Vol. 154, no 1-2, p. 30-40Article in journal (Refereed)
    Abstract [en]

    Motivated by recent experiments in Bose-Einstein condensed atoms that have been confined in toroidal traps, we examine the stability of persistent currents in such systems. We investigate the extent that the stability of these currents may be tunable, and the possible difficulties in their creation and detection.

    Solitary waves in elongated clouds of strongly interacting bosons2005In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 72, no 2, article id 021603Article in journal (Refereed)
    Abstract [en]

    We examine the propagation of solitary waves in elongated clouds of trapped bosonic atoms as the confinement, the strength of the interatomic interaction, and the atom density are varied. We identify three different physical regimes and develop a general formalism that allows us to interpolate between them. Finally we pay special attention to the transition to the Tonks-Girardeau limit of strongly interacting bosons.

    Atom-atom correlations and relative number squeezing in dissociation of spatially inhomogeneous molecular condensates2008In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 78, no 1, article id 011602Article in journal (Refereed)
    Abstract [en]

    We study atom-atom correlations and relative number squeezing in the dissociation of a Bose-Einstein condensate (BEC) of molecular dimers made of either bosonic or fermionic atom pairs. Our treatment addresses the role of the spatial inhomogeneity of the molecular BEC on the strength of correlations in the short time limit. We obtain explicit analytic results for the density-density correlation functions in momentum space, and show that the correlation widths and the degree of relative number squeezing are determined merely by the shape of the molecular condensate.

    Atom-atom correlations in colliding Bose-Einstein condensates2009In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 79, no 2, article id 021606Article in journal (Refereed)
    Abstract [en]

    We analyze atom-atom correlations in the s -wave scattering halo of two colliding condensates. By developing a simple perturbative approach, we obtain explicit analytic results for the collinear (CL) and back-to-back (BB) correlations corresponding to realistic density profiles of the colliding condensates with interactions. The results in the short-time limit are in agreement with the first-principles simulations using the positive- P representation and provide analytic insights into the experimental observations of Perrin [Phys. Rev. Lett. 99, 150405 (2007)]. For long collision durations, we predict that the BB correlation becomes broader than the CL correlation.

    Role of spatial inhomogeneity in dissociation of trapped molecular condensates2010In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 82, no 1, article id 013641Article in journal (Refereed)
    Abstract [en]

    We theoretically analyze dissociation of a harmonically trapped Bose-Einstein condensate of molecular dimers and examine how the spatial inhomogeneity of the molecular condensate affects the conversion dynamics and the atom-atom pair correlations in the short-time limit. Both fermionic and bosonic statistics of the constituent atoms are considered. Using the undepleted molecular-field approximation, we obtain explicit analytic results for the asymptotic behavior of the second-order correlation functions and for the relative number squeezing between the dissociated atoms in one, two, and three spatial dimensions. Comparison with the numerical results shows that the analytic approach employed here captures the main underlying physics and provides useful insights into the dynamics of dissociation for conversion efficiencies up to 10%. The results show explicitly how the strength of atom-atom correlations and relative number squeezing degrade with the reduction of the size of the molecular condensate.

    First-principles quantum dynamics for fermions: Application to molecular dissociation2010In: Europhysics letters, ISSN 0295-5075, E-ISSN 1286-4854, Vol. 92, no 3, article id 36003Article in journal (Refereed)
    Abstract [en]

    We demonstrate that the quantum dynamics of a many-body Fermi-Bose system can be simulated using a Gaussian phase-space representation method. In particular, we consider the application of the mixed fermion-boson model to ultracold quantum gases and simulate the dynamics of dissociation of a Bose-Einstein condensate of bosonic dimers into pairs of fermionic atoms. We quantify deviations of atom-atom pair correlations from Wick's factorization scheme, and show that atom-molecule and molecule-molecule correlations grow with time, in clear departures from pairing mean-field theories. As a first-principles approach, the method provides benchmarking of approximate approaches and can be used to validate dynamical probes for characterizing strongly correlated phases of fermionic systems.

    Stochastic simulations of fermionic dynamics with phase-space representations2011In: Computer Physics Communications, ISSN 0010-4655, E-ISSN 1879-2944, Vol. 182, no 9, p. 1999-2003Article in journal (Refereed)
    Abstract [en]

    A Gaussian operator basis provides a means to formulate phase-space simulations of the real- and imaginary-time evolution of quantum systems. Such simulations are guaranteed to be exact while the underlying distribution remains well-bounded, which defines a useful simulation time. We analyse the application of the Gaussian phase-space representation to the dynamics of the dissociation of an ultra-cold molecular gas. We show how the choice of mapping to stochastic differential equations can be used to tailor the stochastic behaviour, and thus the useful simulation time. In the phase-space approach, it is only averages of stochastic trajectories that have a direct physical meaning. Whether particular constants of the motion are satisfied by individual trajectories depends on the choice of mapping, as we show in examples.

    On the spin asymmetry of ground states in trapped two-component Fermi gases with repulsive interactions2007In: Journal of Physics B: Atomic, Molecular and Optical Physics, ISSN 0953-4075, E-ISSN 1361-6455, Vol. 40, no 13, p. 2653-2660Article in journal (Refereed)
    Abstract [en]

    We examine the spin asymmetry of ground states for two-dimensional, harmonically trapped two-component gases of fermionic atoms at zero temperature with weakly repulsive short-range interactions. Our main result is that, in contrast to the three-dimensional case, in two dimensions a non-trivial spin-asymmetric phase can only be caused by the shell structure. A simple, qualitative description is given in terms of an approximate single-particle model, comparing well to the standard results of Hartree-Fock or direct diagonalization methods.

    There’s more to the multimedia effect than meets the eye: is seeing pictures believing?2017In: Instructional science, ISSN 0020-4277, E-ISSN 1573-1952, Vol. 45, no 2, p. 263-287Article in journal (Refereed)
    Abstract [en]

    Textbooks in applied mathematics often use graphs to explain the meaning of formulae, even though their benefit is still not fully explored. To test processes underlying this assumed multimedia effect we collected performance scores, eye movements, and think-aloud protocols from students solving problems in vector calculus with and without graphs. Results showed no overall multimedia effect, but instead an effect to confirm statements that were accompanied by graphs, irrespective of whether these statements were true or false. Eye movement and verbal data shed light on this surprising finding. Students looked proportionally less at the text and the problem statement when a graph was present. Moreover, they experienced more mental effort with the graph, as indicated by more silent pauses in thinking aloud. Hence, students actively processed the graphs. This, however, was not sufficient. Further analysis revealed that the more students looked at the statement, the better they performed. Thus, in the multimedia condition the graph drew students’ attention and cognitive capacities away from focusing on the statement. A good alternative strategy in the multimedia condition was to frequently look between graph and problem statement, and thus to integrate their information. In conclusion, graphs influence where students look and what they process, and may even mislead them into believing accompanying information. Thus, teachers and textbook designers should be very critical on when to use graphs and carefully consider how the graphs are integrated with other parts of the problem.

    Directional effects due to quantum statistics in dissociation of elongated molecular condensates2009In: Physical Review A. Atomic, Molecular, and Optical Physics, ISSN 1050-2947, E-ISSN 1094-1622, Vol. 79, no 4, article id 043624Article in journal (Refereed)
    Abstract [en]

    Ultracold clouds of dimeric molecules can dissociate into quantum mechanically correlated constituent atoms that are either both bosons or both fermions. We theoretically model the dissociation of two-dimensional anisotropic molecular condensates for which this difference manifests as complementary geometric structures of the dissociated atoms. Atomic bosons are preferentially emitted along the long axis of the molecular condensate, while atomic fermions are preferentially emitted along the short axis. This anisotropy potentially simplifies the measurement of correlations between the atoms through relative number squeezing.

    Super-shell structure in harmonically trapped fermionic gases and its semi-classical interpretation2006In: Physica Scripta, ISSN 0031-8949, E-ISSN 1402-4896, no T125, p. 37-40Article in journal (Refereed)
    Abstract [en]

    It was recently shown in self-consistent Hartree–Fock calculations that a harmonically trapped dilute gas of fermionic atoms with a repulsive two-body interaction exhibits a pronounced super-shell structure: the shell fillings due to the spherical harmonic trapping potential are modulated by a beat mode. This changes the 'magic numbers' occurring between the beat nodes by half a period. The length and amplitude of the beating mode depends on the strength of the interaction. We give a qualitative interpretation of the beat structure in terms of a semi-classical trace formula that uniformly describes the symmetry breaking U(3) → SO(3) in a three-dimensional harmonic oscillator potential perturbed by an anharmonic term ∝ r 4 with arbitrary strength. We show that at low Fermi energies (or particle numbers), the beating gross-shell structure of this system is dominated solely by the twofold degenerate circular and (diametrically) pendulating orbits.

    Kulturella orsaksförklaringar till mäns våld mot kvinnor: En jämförelse av debatten om hedersvåld och våldtäkt2011Student paper other, 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Detta arbete syftar till att studera hur det talas om kulturella orsaksförklaringar till mäns våld mot kvinnor i den svenska debatten. För att exemplifiera används hedersvåld från män med bakgrund i Mellanöstern samt våldtäkt från män med bakgrund i Sverige som utgångspunkter. Detta sker genom en komparativ litteraturstudie med en konstruktivistisk kunskapssyn som bas.

    Resultatet visar att de som förespråkar att hedersvåld skulle vara kultur gärna poängterar att det närmaste kollektivet stödjer gärningsmannen. De understryker även att föreställningar om mångfald inte får gå före individers mänskliga rättigheter. Debattörerna som istället är motståndare till att hedersvåld skulle vara kultur poängterar det universella i problemet mäns våld mot kvinnor. Man menar att könsmaktsordningen borde vara i fokus. Något annat anses vara en konsekvens av främlingsfientlighet.

    De som förespråkar att våldtäkt skulle vara kultur menar att olika samhälleliga instanser bagatelliserar problemet och indirekt även legitimerar agerandet. Media och rättsväsende skuldbelägger kvinnan samt har fördomar om att en våldtäktsman inte kan vara vanlig. Andra, som är motståndare till att våldtäkt skulle vara kultur, påtalar istället med emfas att det är en traumatisk barndom och en känsla av utanförskap som leder till brottet. Några menar även att våldtäkt är en del av människans naturliga biologi.

    Vid en jämförelse av de båda samtalen framkommer att debattörerna använder helt olika argument när de talar om hedersvåld respektive våldtäkt. Detta beror i mångt och mycket på att kulturbegreppet används på skilda vis. Debatterna har emellertid också gemensamma nämnare i det att förövarna sällan har tillräckligt med distans för att erkänna sina gärningar. Det förekommer även ett unisont skuldbeläggande av den utsatta kvinnan från omgivningen. Många argument handlar dessutom om ifall man kan dela upp världen i ett ”vi och dom” eller inte.

    Slutsatsen är att det är vanskligt att fastna i ett tänkande som säger att ett problem antingen är kultur eller inte alls. Det är viktigt att se till samspelet mellan kulturer samt individer och strukturer. Man bör även hitta en balans mellan ett dynamiskt och ett statiskt kulturbegrepp eftersom ansvaret då fördelas mer nyanserat.

    Genus som den deliberativa kommunikationens utmaning: En klassrumsstudie av isärhållande och hierarki2012Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här studien syftar till att undersöka genuskonstruerande i en specifik gymnasieklass samt analysera dess betydelse för deliberativ kommunikation. Utgångspunkterna i studien är alltså dels ett utbildningsideal – dels en genusteori. Deliberativ kommunikation är en samtalsform med målet att flera aspekter av en fråga ska bli beaktade i ett respektfullt samtal där alla fritt får säga sin mening och bli lyssnade till. Genus ses som konstruerat och föränderligt, samtidigt som det finns normer som ger kontinuitet. Detta har i klassen studerats genom observationer utifrån en etnografisk metodansats. Resultatet visar att den genusdikotomi som finns i klassrummet kring vem som pratar med vem ger brist på perspektiv i samtalen. Vidare avgör den genushierarki som finns vems röst som blir lyssnad till. Genus har också visat sig vara normerande för vem som får tala. Slutsatserna av studien är att genuskonstruerande är en utmaning i dubbel bemärkelse för den deliberativa kommunikationen.

    Abstract [sv]

    Den 24 oktober 2012 utför samhällsprogrammet Kalla Fakta en kritisk granskning av modeimperiet H&M, där man ifrågasätter H&M:s handlande angående levnadslönerna för textilarbetarna i deras produktionsländer. I denna uppsats är syftet att undersöka om H&M valt att försvara sig mot denna granskning i en korrespondens med Kalla Fakta. Det är ur ett retoriskt perspektiv intressant att studera hur ett värdsledande förtetag, som H&M, strategiskt väljer att svara på denna typ av situation för att försöka återuppta sin trovärdighet. I denna studie har jag med hjälp av retorikens statuslära och William L. Benoits apologia-teorier, kunnat konstatera att H&M använt sig av olika försvarstrategier som  förändras över tid i korrespondensen.  I denna studie har jag även kunnat konstatera att korrespondensen är en del av H&M:s återhämtningsarbetet i försök att förstärka deras ethos och till viss del reducera den bild som Kalla Fakta valt att målat upp av företaget.

    Managing conflicting goals in pig farming: farmers’ strategies and perspectives on sustainable pig farming in Sweden2017In: International Journal of Agricultural Sustainability, ISSN 1473-5903, E-ISSN 1747-762X, Vol. 15, no 6, p. 693-707Article in journal (Refereed)
    Abstract [en]

    Industrial meat production has several negative environmental effects. Governments’ agricultural policies aim for cost efficiency combined with high environmental and animal welfare, which puts farmers in a difficult situation trying to navigate between sometimes contradictory requirements. This paper studies how Swedish pig farmers resolve or cope with conflicting goals in pig farming. We have analysed the regulations governing EU and Swedish pig farming. We have also interviewed five Swedish pig farmers about their views of the different goals of pig farming and strategies for resolving conflicts between the goals of low environmental impact, high animal welfare and enough profitability to continue farming. The greatest divide was between the conventional farmers, who emphasized natural resource efficiency, and the organic farmers who stressed animal welfare, multifunctionality and ecosystem service delivery. We suggest four strategies to contribute to resolving some of the conflicting goals: improve communication about different types of pig farming; use public procurement as a driver towards more sustainable pork production; work towards improving the Common Agricultural Policy, perhaps by implementing payments for ecosystem services or multifunctionality; and finally, decrease the total production of pork to lower the emissions per land unit.

    Abstract [en]

    The society encourages individuals to promote their health habits in order to improve their well-being. The aim was to investigate the effect of different types of physical activity on experience of general health in well-being in men and woman. Sixty men and women in ages 25-50 years old were randomly chosen from training facilities to answer the 12-item General Health Questionnaire (GHQ-12) and Swedish Core Affect Scale (SCAS). The results showed a significant increase in positive well-being due to the practice of physical activity, but there were no gender difference. However, it was found a significant interaction effect of age and physical activity on health, the men who walked and women who conditioning trained showed highest well-being and general health. The conclusion was that the well-being increase regardless of sex after physical activity, however, different activities gave varying increases between the sexes.

    Universitetsstudenters uppfattning om aktivitet, ett centralt begrepp inom arbetsterapi2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning: Som arbetsterapeut är det viktigt att kunna skilja på betydelsen och innehållet av aktivitet inom ramen för arbetsterapi från en mer allmän betydelse. Om dimensionerna av aktivitet skulle kunna beskrivas utifrån empiriska data skulle det kunna bidra till en djupare förståelse av begreppet och dess relation till hälsa skulle ytterligare kunna tydliggöras. Syftet med studien var att undersöka hur studenter vid Örebro universitet uppfattade begreppet aktivitet, samt om det fanns skillnader i uppfattning beroende på kön eller akademitillhörighet. För att säkerställa att studenter från alla berörda akademier på universitetet blev representerade i urvalet valdes ett stratifierat slumpmässigt urval. Datainsamling skedde genom gruppenkäter. Enkätens påståenden utformades från resultatet av två empiriska studier om begreppet aktivitet. Insamlad data bearbetades och analyserades med hjälp av statistikprogrammet Statistical Package for Social Science [SPSS]. Svarsfrekvensen var 99 procent. Av 222 inkluderade respondenter var 53 procent kvinnor och 47 procent män. Överlag instämde majoriteten respondenter helt eller delvis i påståendena fördelade på fem olika kategorier. Störst medhåll av alla frågor fick ”aktivitet utförs av alla oavsett ålder” där 82 procent instämde helt. Slår man ihop andelen som instämde helt och delvis fick ”aktivitet påverkar min personliga utveckling” störst medhåll med 96 procent. Störst avstånd togs till att ”aktivitet påverkar min hälsa negativt”, där 50 procent angav att de inte instämde alls. Ett Mann-Whitney test visade på signifikanta skillnader mellan kvinnor och män i 17 av 50 variabler. Kvinnorna instämde i högre grad än männen på samtliga av dessa, något som kan bero på att enkätens påståenden i huvudsak beskrev aktivitet från ett kvinnligt perspektiv. Ett Kruskal-Wallis test visade att det fanns signifikanta skillnader mellan studenter från olika akademier avseende 10 av 50 variabler, skillnader som till viss del kunde härledas till studenternas framtida yrkesval. I huvudsak uppfattade studenter vid Örebro universitet aktivitet som något som: utförs av alla oavsett ålder; är att göra; kan vara något vi gör under hela våra liv; skiljer sig från person till person; påverkas av personliga värderingar och intressen, samt är något som påverkar vår personliga utveckling. Det fanns ett tydligare instämmande från respondenterna gällande vad vi gör och varför, jämfört med hur vi gör det.

    Möjligheter och hinder vid implementering av StegVis 1: En enkätundersökning riktad till StegVis-utbildade pedagoger i förskolan/skolan i norra Örebro län2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The research of implementation processes in the public health area is still relatively limited. Implementation concerns the procedure of putting into action a new method or program into an organization’s internal, everyday operation. Implementation encompasses the realization of, and the carrying through of, for example a program, but an important aspect is also that the implementation has the desired effect. To make sure that the result of a method in practice will be positive, it is of greatest importance that the implementation works. It does not matter how well the method works, if it does not have the support of the organization.

    Purpose: The purpose of this study was to examine possibilities and obstacles of implementation of a program in social and emotional learning, Second Step, among 4-6 year olds in preschool/school. Method: On assignment from the public health team in the counties in northern Örebro, an evaluation of the implementation of the program in the four municipalities Lindesberg, Nora, Hällefors and Ljusnarsberg was performed. The sample consisted of all educationalists that had completed the Second Step 1 training, a total of 182 individuals. A quantitative approach was chosen, as the idea was to reach a greater number of educationalists. Data was collected through a questionnaire and analyzed with the help of SPSS and a simple kind of content analysis.

    Result: The reply frequency was 37%, which is too low for a generalization of the result. 72% of the respondents worked at a preschool/school that at the time used Second Step 1 in the organization. All in all, about 90% of the respondents had worked at a preschool/school that had used Second Step 1 in the organization at some point. Most of the respondents were pleased with Second Step as a program. The majority of the respondents stated that the practical introduction of Second Step had functioned well and the fidelity was relatively high with a few exceptions. Factors that have made the implementation of Second Step possible is need for social and emotional learning, positive attitudes, leader support, visible effects of the program, access to premises, flexibility and settled times. Factors that have proven to be obstacles for the implementation of Second Step are problems with the group composition, lack of support from colleagues,lack of access to premises and lack of time to plan and perform.

    Discussion/conclusions: Theresult has been put in relation to earlier research and the discovered tendencies correspond well with earlier theories and models. Second Step indicates to be relevant as a program, though the need of social and emotional learning in preschool/school seems to exist, which at an early stage makes the implementation possible. Other facilitating implementation factors tend to vary in importance depending on where in the process the program is. Overall, the fidelity is satisfactory, but it would probably have been more beneficial with clearer goals and guidelines for the program in the organizations. An evaluating exchange meeting could have been valuable to facilitate the program skill development among the educationalists.

    Future research: One example for future studies can be to put more focus on those who stop using the program and reasons for this. This study may also be a basis for, and facilitate, future studies, especially considering the method and discussion of the method which can contribute to improve control over the survey in similar studies.

    Relatives in end-of-life care – part 2: a theory for enabling safety2007In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 16, no 2, p. 382-390Article in journal (Refereed)
    Abstract [en]

    AIM: To develop a goal-oriented praxis theory for enabling safety for relatives when an adult or older patient is close to end-of-life.

    BACKGROUND: This is the second part of a project focusing on the situation and needs of relatives in end-of-life care. Our interpretation of the existing corpus of knowledge pertaining to the needs of close relatives in this situation showed the significance of relatives' need for safety.

    METHOD: The theory was developed step-by-step, through triangulation of critical review of empirical research in the field, our own clinical experiences from end-of-life care, renewed literature searches and theoretical reasoning.

    THEORY: The foundation for the theory is taken from the ethical intention of the philosopher Paul Ricoeur. From this, the theory focuses on relatives in the context of end-of-life care with the goal of enabling safety. This is proposed by four aphorisms functioning as safety enablers and these are directed towards the professional's approach and attitude, the relative's concern for the patient, the specific situation for the relative and the patient's end-of-life period as a period in the life of the relative.

    RELEVANCE TO CLINICAL PRACTICE: Implications for end-of-life practice are considered and include aspects for promotion of just institutions in end-of-life care, the significance of negotiated partnership in end-of-life care, enabling safety for relatives living in existential and practical uncertainty in connection with end-of-life care and diversity of relatives' preferences as they live through this particular period.

    The Eastward Enlargement of European Parties: Party Adaptation in the Light of EU-enlargement2013Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The aim of the study is to map out and analyse the integration of political parties from Central and Eastern Europe into the main European party families. The prospect of eastern enlargement of the EU implicated opportunities and above all challenges for the West European party families. The challenges consisted of integrating new parties with a different historical legacy. The study focuses on mainly how the European party families handled these challenges and what motives that have driven them in this engagement. At a more general level the thesis sketches two alternatives interpretations of the process: Western neo-colonialism and contribution to democratisation. The method used for the study is comparative case-study method and the main sources that have been utilised are party documents and in-depth interviews. The study is delimited to the three main European party families: the Christian democrats, the social democrats and the liberals. The countries of interest in Central and Eastern Europe are those postcommunist countries that became EU-members in 2004 and 2007: Bulgaria, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Slovenia. The time-frame is limited to the first party contacts in 1989 to the final inclusion of the new parties in 2000-2006.

    The results suggest that the European parties have responded with ambitious means to the challenge of integrating new parties from a postcommunist context. They have set up new coordinating bodies and organised educational programmes for the applicant parties, mainly directed to young politicians. The Christian democrats and the social democrats have also used parallel organisations as buffer-zones, which provided certain flexibility. As for motives, the Christian democrats stand out as the party family with the clearest power-oriented motives. At the other end, the liberals stand out as the party family that is most steered by ideology and identity. The social democrats went through a change with ideological considerations dominating the early phase and became increasingly poweroriented as the EU enlargement drew closer. When it comes to the two alternative interpretations of this process, the main conclusion is that they are intertwined and more or less impossible to separate from each other.

    Ideologisk konvergens mellan öst och väst?: de europeiska partifamiljerna 1990-20132015In: Nordisk Østforum, ISSN 0801-7220, Vol. 29, no 2, p. 167-189Article in journal (Refereed)
    Abstract [en]

    In this paper we compare ideological positions of political parties in Eastern and Western Europe. As the Communist regimes collapsed and new democracies began to emerge in Eastern Europe, it became obvious that historical and cultural differences existed in relation to Western Europe. This was not least visible among the political parties. When the West European parties initiated contacts with potential sister parties in the East, noticeable differences were revealed in several issues. In general, the eastern parties appeared to be more nationalist, more populist and less tolerant towards minorities than their Western sister parties. The question raised in this paper is whether these differences, have faded or not during the 25-year period after 1989. In order to perform this analysis, the three largest and most influential party families are selected: the Christian Democratic EPP, the Social Democratic PES and the Liberal ALDE. Departing from election manifesto data compiled by the Comparative Manifesto Project, we have performed a time series analysis ranging from 1990 to 2013. Here, the Eastern parties are compared to their Western sister parties within each party family. Firstly, they are compared along the general left-right dimension, and secondly they are compared in specific issues, which have been conceived as delicate matter: the view on the EU, nationalism and view on multiculturalism.

    Cykler och loopar i Salongen: En studie av återkoppling i frisörklassrummet2015Licentiate thesis, monograph (Other academic)
    Abstract [en]

    The interest in this empirical study aims at assessment, more precisely feedback as part of ordinary activities within hairdressing education. The study investigates feedback practices related to assessment of knowing during production, with focus on communication between student and teacher. Communication is regarded as interactively constructed and is investigated through a multimodal social semiotic perspective which implies studying verbal as well as nonverbal resources in meaning making. Speech and body movements are not subordinate to each other and are studied as contributing in communication on their own terms.

    Video observations were used to investigate feedback practices in the hairdressing classroom, during a couple of lessons when last year’s students received customers for various treatments. From one hour recording, a selection was made showing communication between student and teacher with joint focus of attention during production. The selection is based on the assumption of feedback as interactively constructed and represented in a multimodal way.

    The analysis of the feedback practice shows a multifaceted result, since each interaction between a student and a teacher is unique. Nevertheless, a recurrent pattern of feedback construction could be discerned. Three important functions of feedback were distinguished, that of control, instruction and evaluation. Furthermore, these functions interact in temporal processes of cycles and loops. The core of feedback practice is found within the loop, where questions and wonders from the student are brought into a joint investigation.

    Diskursordning och hegemoni: Representationer av en skola2012Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This article uses discourse analysis from a multivalent perspective to research newspaper articles, a scientific article, an institutional newsletter, blogs and a reportage written on the subject of a specific comprehensive school in Sweden which has become known for its successful development in pupils’ achievements. According to this article the picture given of the school in the media is very positive, until the time when one article in a newspaper, followed by a blog, changed the order of discourse in a hegemonic way. This article describes the discursive change in relation to the social and historical context within the education policy, one largely dominated by a neoliberal ideology, which focuses more on measuring and ranking than on school improvement in terms of inclusion and learning.

    Abstract [en]

    Olika kameror ger fler perspektiv och således ett rikare datamaterial. Denna metodartikel beskriver erfarenheter av användning av huvudkamera och handkamera i videoobservationer och diskuterar hur användning av fler kameror kompletterar varandra. Datamaterialet består av 20 timmars film varav 10 timmar även har spelats in med huvudkamera. Sammantaget visar datainsamlingsmetoden hur huvudkameran erbjuder möjligheter att komma nära det som deltagarna talar om och gör. Kameran följer bärarens rörelser och blick på ett sätt som en handkamera inte lyckas fånga. I de studerade aktiviteterna, ger huvudkameran närbilder av materialet deltagarna arbetar med samt av hur de riktar sin uppmärksamhet och vad de talar om. Eftersom inspelning görs samtidigt både med huvudkamera och handkamera, kan materialet i olika filmerna jämföras. Användningen av huvudkamera har inte bara fördelen av att ge närbilder, utan den tillför detaljer från det arbetsmaterial deltagarna interagerar med och i, vilket inte synliggörs med enbart handkameran. Däremot har handkameran fördelen att kunna avbilda fler deltagare samtidigt och den kontext de befinner sig i. Artikeln konkluderar med hur inspelning med fler rörliga kameror är en lämplig metod för videoobservation eftersom det visar studieobjektet ur fler perspektiv.

    Abstract [sv]

    Artikeln, med sitt utbildningssociologiska perspektiv, har sin bakgrund i empiriska studier där intresset är riktat mot klassrumsbaserad bedömning, närmare bestämt återkoppling som en del av den dagliga undervisningen. Data konstruerades genom videoobservationer i frisörklassrummet. Analyserna av återkopplingspraktikerna synliggör lärares professionella yrkeskunnande steg för steg, koordinerade med och i respons till eleverna. Dessa empiriskt baserade resultat ställs i kontrast till neoliberalt färgad utbildningspolitik, som framkommer ur några centrala dokument och artiklar, där professionellt yrkeskunnande reduceras och yrkesutbildning generaliseras till instrumentella nyckelkompetenser och anställningsbarhet.

    Twist and shape: Feedback practices within creative subject content of hairdressing education2018In: Vocations and Learning, ISSN 1874-785X, E-ISSN 1874-7868, Vol. 11, no 3, p. 425-448Article in journal (Refereed)
    Abstract [en]

    The aim of this study is to explore feedback practices and how such actions of assessment emerge from embodied participation in classroom interactions between teachers and students. Using video recordings of teacher and student interactions in hairdressing education, I look at how feedback practices within creative subject content are produced between the participants as social actions situated in interaction, using conversation analysis. Feedback is contingent upon an embodied moment-to-moment monitoring and collaboration between the teacher and student, and is organized as a trajectory from problem detection through exploration until a final solution is found. Feedback within creative subject content is displayed as a multifarious exploration of embodied as well as materially situated professional knowledge. Overall, the findings show how feedback is mutually produced in a process, making tacit dimensions of hairdressers’ knowing explicit. This allows for improving the quality of the work over time in a trajectory of problem solving phases gradually displaying how to assess creative subject content of the material product worked on.

    Återkoppling i interaktion: En studie av klassrumsbaserad bedömning i frisörutbildningen2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The present dissertation concerns social organization of feedback in ongoing hairdressing education. The central aim is to explore feedback between teacher and student in multimodal interaction within classroom assessment, as co-production of action and student’s participation. Classroom assessment and feedback are understood as social actions situated in interaction.

    The empirical data consists of video recordings from two vocational schools. From 31 hours of video material, selections of feedback interactions were made. At first, teacher and student communication in feedback cycles and loops was analysed from a social semiotic perspective. Secondly, examples of student initiated feedback loops were analysed from a conversation analytic perspective. Thirdly, a single case of a teacher and a student interacting through feedback related to creative subject content was analysed from a conversation analytic perspective. 

    The analyses show the importance of collaborative use of artefacts and embodied communication in the production of mutual understanding; opening for student initiatives in actions of assessment as well as feedback. Silence and body position were found to be important resources giving the student space to display concern. Participation in feedback practices within creative subject content emerged in a trajectory of problem detection to problem solving, resulting in tacit dimensions of hairdressers’ knowing made explicit.

    The findings indicate the importance of taking a participatory perspective on multimodal interaction when exploring actions of assessment and feedback between teacher and student. This study shows how feedback is not only given from the teacher, but also locally produced as a collaborative practice between teachers and students, displaying tacit dimensions of professional knowledge and subject content.

    Abstract [en]

    The aim of this study is to explore feedback practices in situated activities and how such actions of assessment emerge from embodied participation in classroom interactions between teachers and students. Using video recordings of teacher and student interactions in hairdressing education, we investigate through conversation analysis how feedback practices such as making loops are initiated and enabled between the participants in situated activities. Feedback in the practice of loops is contingent upon an embodied moment-to-moment monitoring and collaboration between the teacher and student, and is initiated with a concern from the student that is responded to by the teacher, enabling feedback to become a common exploration of professional knowledge. Overall, the findings show how feedback is mutually produced, making visible that salient aspects of the education are emanating from the student’s own concern.

    Den etiska tendensen i utbildning för hållbar utveckling: meningsskapande i ett genomlevandeperspektiv2006Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall aim of this thesis is to contribute to the debate about Education for Sustainable Development (ESD), and provide a practical tool for teachers with which they can relate to ethical and moral learning in the ESD context. This aim is based on the ambition to develop an approach that takes its starting point from our practical experience of ethics and morals, inspired by the later works of Ludwig Wittgenstein and the transactional perspective developed by John Dewey. This implies that ethics and morals are regarded as a human tendency that is observable in action. The central method used to clarify ethical and moral meaning-making is, by the use of examples, to remind of common experiences of how this meaning-making appears in everyday situations. These clarifications are made in order to dissolve (rather than solve) philosophical problems, as well as to create new knowledge. The approach has been applied to four different studies. The first study focuses on the differences between three selective traditions in environmental education: fact-based, normative and pluralistic, with regard to the relationship between facts and values. It is argued that a pluralistic approach can be seen as way of relating facts and values in practice, and consequently that the democratic process neither precedes nor succeeds education but is an integral part of it, and that students therefore are constituted as citizens participating in the progress of sustainable development. The purpose of the second study is to suggest an approach that allows in situ analysis of how individuals’ prior experiences are included in the processes of moral meaning-making. A concrete example shows how individuals can transform the moral discourse in different situations. In the third study, it is suggested that the ethical tendency can be recognised as a communication in which certain values and actions are treated as if they were universally good and right. Three different kinds of situations in which this communication appears are highlighted: personal moral reactions, norms for correct behaviour and ethical reflections.The diverse conditions for learning in these situations are discussed, and specific notice is taken of the risk of indoctrination in ESD. The fourth study addresses the question of how to understand and deal with criticism in a pluralistic educational approach. Through reminders of how criticism appears in everyday practice, it is argued that criticism does not necessarily have to be understood theoretically. Criticism can also be seen as the diverse ways in which human beings morally react, encounter different norms and ethically reflect.

    Abstract [en]

    This article aims to contribute to the debate about the moral and ethical aspects of education for sustainable development by suggesting a clarification of ethics and morals through an investigation of how these aspects appear in educational practice. The ambition is both to point to the normative dangers of education for sustainable development and the possibilities to enhance pluralism. The Wittgenstein-inspired approach used means that ethics and morals are regarded as expressions of a particular human tendency--the ethical tendency--that is observable in communication. The findings suggest that the ethical tendency appears in three different kinds of situations: "personal moral reactions," "norms for correct behaviour," and "ethical reflections." We discuss the diverse learning conditions of these situations and take specific notice of the risk of indoctrination. (Contains 12 notes.)

    4. Pluralism and criticism in environmental education and education for sustainable development: a practical understanding

    2006 (English)In: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871, Vol. 12, no 2, p. 149-163Article in journal (Refereed) Published
    Abstract [en]

    Education is presented with a challenge when faced with criticism of modern science and adoption of a pluralistic view of environmental education and education for sustainable development. In dealing with this challenge, a practical understanding inspired by the later works of Ludwig Wittgenstein is suggested as a complement to more traditional theoretical and analytical responses. Through reminders of how criticism appears in everyday practice, the article shows that criticism does not necessarily have to be understood solely by reference to specific theoretical positions, but can also be seen in terms of the diverse ways that human beings react morally, encounter different norms and conduct ethical reflection. In such a practical understanding, the question is not whether the criticism is correct or not in absolute terms but rather whether the opinions and perspectives have significance in people's lives. Criticism of modern science does not therefore appear to be a reason to exclude modern science, the proposal here being to acknowledge and embrace the criticism and the alternative views put forward by the critics. By means of a practical understanding, the opposition expected between criticism and pluralism can be dissolved, rather than solved.

    Abstract [sv]

    EXPERIENCE AND MEANING MAKING. The purpose of this article is to contribute to the progress of the sociocultural perspective on learning by suggesting an approach that allows for an in situ analysis of how individuals’ prior experiences take part in the processes of meaning making, and that also takes sociocultural activity into consideration. The philosophical and methodological basis for this approach consists of a combination of Dewey’s transactional perspective on meaning making and Wittgenstein’s first-person perspective on language use. The article contains an empirical example that illustrates this approach. The substantial knowledge resulting from this analysis shows how prior experiences are re-actualised in an event and thus participate in the process of meaning-making, as well as contributing to the substance of the meanings made.

    Om didaktikens möjligheter: ett pragmatiskt perspektiv2014In: Utbildning och Demokrati, ISSN 1102-6472, E-ISSN 2001-7316, Vol. 23, no 3, p. 33-52Article in journal (Refereed)
    Abstract [en]

    The possibilities of didactics – a pragmatist perspective. In this inaugural speech I develop my view on the concept of didactics, didactic research and the importance of didactics in the current educational policy context. I claim that the subject of Education can play an important role in the development of didactics due to its long history of didactic concerns and its comprehensive theories about teaching and learning. I particularly emphasize the opportunities that I believe lie in a didactic perspective grounded in Dewey’s pragmatic philosophy. In my opinion Dewey’s work is still highly relevant and can offer a basis for political arguments, pedagogic guidance, methodological alternatives and a way to resolve essential philosophical problems. Furthermore, I highlight environmental and sustainability issues as a new political moral dimension of education which puts education in a genuine and long-term perspective for the future. I argue that this dimension, along with Dewey’s approach to education, is an important corrective to the educational policy tendencies that want to reduce education to a short- term issue of knowledge transfer, individual success and competitiveness of the business sector.
