    Around multivariate Schmidt-Spitzer theorem2014In: Linear Algebra and its Applications, ISSN 0024-3795, E-ISSN 1873-1856, Vol. 446, p. 356-368Article in journal (Refereed)
    Abstract [en]

    Given an arbitrary complex-valued infinite matrix $\infmatA=(a_{ij}),$$i=1,\dotsc,\infty;$ $j=1,\dotsc,\infty$  and a positive integer $n$ we introduce anaturally associated  polynomial basis $\polybasis_\infmatA$ of$\C[x_0,\dotsc,x_n]$.We discuss some properties of the locus of  common zeros of all polynomials in $\polybasis_A$ having  a given degree $m$; the latter locus can beinterpreted as the spectrum of the $m\times (m+n)$-submatrix of $\infmatA$ formed by its  $m$ first rows and$(m+n)$ first columns. We initiate the study of the asymptotics of these spectra when $m\to \infty$ inthe case when $\infmatA$ is a banded Toeplitz matrix.In particular, we present and partially prove a conjectural multivariate analogof the well-known Schmidt-Spitzer theorem which describes  the spectral asymptotics for the sequence of principal minors of an arbitrarybanded Toeplitz matrix.Finally, we discuss relations between polynomial bases $\polybasis_\infmatA$ andmultivariate  orthogonal polynomials.

    Discriminants, Symmetrized Graph monomials and Sums of Squares2012In: Experimental Mathematics, ISSN 1058-6458, E-ISSN 1944-950X, Vol. 21, no 4, p. 353-361Article in journal (Refereed)
    Abstract [en]

    In 1878, motivated by the requirements of the invariant the-ory of binary forms, J. J. Sylvester constructed, for every graphwith possible multiple edges but without loops, its symmetrizedgraph monomial, which is a polynomial in the vertex labels ofthe original graph. We pose the question for which graphs thispolynomial is nonnegative or a sum of squares. This problem ismotivated by a recent conjecture of F. Sottile and E. Mukhin onthe discriminant of the derivative of a univariate polynomial andby an interesting example of P. and A. Lax of a graph with fouredges whose symmetrized graph monomial is nonnegative butnot a sum of squares. We present detailed information about sym-metrized graph monomials for graphs with four and six edges,obtained by computer calculations.

    Hur beskriver studenter lärares bedömning?: Vad kan lärarstudenten som VFU-handledaren inte kan?2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Lärare använder sig av allt från summativ bedömning och fingertoppskänsla till beprövad didaktisk erfarenhet och formativ bedömning, när elevers kunskaper ska bedömas. Forskning visar att den största framgången för elevers lärande och kunskapsutveckling sker då formativ bedömning används.

    Syftet med denna studie är att studera hur blivande lärarstudenter beskriver lärares bedömningspraktiker under den verksamhetsförlagda utbildningen. Vad upplever studenterna i praktiken av lärares bedömning jämfört med teorin från lärarutbildningen?

    Det empiriska materialet, bestående av 18 examinationsuppgifter från lärarstudenter i Didaktik II, sammanställs och tolkas med inspiration utifrån det hermeneutiska tankesättet. Studenttexterna tolkas utifrån de begrepp som studenterna enligt examinationsuppgiften förväntades att studera från sin VFU- verksamhet. Det empiriska materialet beskrivs, analyseras och resultatet jämförs i relation till forskningsfrågorna.

    Resultatet av undersökningen visar att lärare inte alltid gör som de säger samt att studenterna visar att de ännu inte helt erövrat den praktiska erfarenheten, som en lång lärarpraktik innebär. Studenterna har emellertid med sig de senaste teorierna om bedömning av och för elevers lärande och kunskapsutveckling. Denna studie visar att en viss diskrepans tycks råda mellan teori och praktik.

    Den emotionella kraften: En etnologisk studie i abortdiskursen2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med syfte att undersöka hur diskursen som kulturellt meningsskapande resulterar i kollektiva uppmaningar till disciplinering, i detta fall av kvinna som föreställd moder, klarlägger studien hur de meningsproducerande sociala maktprocesserna möjliggörs och vidmakthålls. Förenad med den politiska diskursteorins förståelse för hur de rådande normerna och värderingarna påverkar individers handlingsutrymme, utreder uppsatsen den juridiska apparatens och den offentliga styrningens diskursiva upprepning av folkhemmets reproduceringspolitik. Med intervjumaterial visar studien hur erfarenheten av hemabort resulterar i en internaliseras självdisciplinering av kroppen hos kvinnan. Den offentliga styrningens verbala praktiker klargör abortdiskursens sociala kulturprocess och dess maktstruktur.

    Reimagining the city through art: Tactics, opportunities and limitations from Experiment Stockholm2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The transformation of cities is a challenge of global significance that will depend on the capacity to re-imagine the potential of cities, and thus needs more than standard technocratic urban planning approaches. Deep engagement with the arts provides one avenue for recasting the future of cities. This thesis explores the question of how ‘critical urban art interventions’ develop alternative ways of knowing urban nature, and the opportunities and limitations of using art to reimagine the future of cities. By drawing on urban political ecology and cultural geography, the thesis documents and explores the aims and tactics used in five urban art interventions to reimagine sites of urban nature in Stockholm. Qualitative interviews and participant observation were carried to explore these questions. Findings suggest that tactics used in urban art interventions promote embodied ways of knowing, and simultaneously interacting with the physical and socio- historical constructions of sites of urban natures.

    Effects of CO2 enrichment on photosynthesis, growth, and nitrogen metabolism of the seagrass Zostera noltii2012In: Ecology and Evolution, ISSN 2045-7758, Vol. 2, no 10, p. 2620-2630Article in journal (Refereed)
    Abstract [en]

    Seagrass ecosystems are expected to benefit from the global increase in CO2 in the ocean because the photosynthetic rate of these plants may be C-i-limited at the current CO2 level. As well, it is expected that lower external pH will facilitate the nitrate uptake of seagrasses if nitrate is cotransported with H+ across the membrane as in terrestrial plants. Here, we investigate the effects of CO2 enrichment on both carbon and nitrogen metabolism of the seagrass Zostera noltii in a mesocosm experiment where plants were exposed for 5 months to two experimental CO2 concentrations (360 and 700 ppm). Both the maximum photosynthetic rate (Pm) and photosynthetic efficiency (alpha) were higher (1.3- and 4.1-fold, respectively) in plants exposed to CO2-enriched conditions. On the other hand, no significant effects of CO2 enrichment on leaf growth rates were observed, probably due to nitrogen limitation as revealed by the low nitrogen content of leaves. The leaf ammonium uptake rate and glutamine synthetase activity were not significantly affected by increased CO2 concentrations. On the other hand, the leaf nitrate uptake rate of plants exposed to CO2-enriched conditions was fourfold lower than the uptake of plants exposed to current CO2 level, suggesting that in the seagrass Z. noltii nitrate is not cotransported with H+ as in terrestrial plants. In contrast, the activity of nitrate reductase was threefold higher in plant leaves grown at high-CO2 concentrations. Our results suggest that the global effects of CO2 on seagrass production may be spatially heterogeneous and depend on the specific nitrogen availability of each system. Under a CO2 increase scenario, the natural levels of nutrients will probably become limiting for Z. noltii. This potential limitation becomes more relevant because the expected positive effect of CO2 increase on nitrate uptake rate was not confirmed.

    Efficient de novo assembly of large and complex genomes by massively parallel sequencing of Fosmid pools2014In: BMC Genomics, ISSN 1471-2164, E-ISSN 1471-2164, Vol. 15, p. 439-Article in journal (Refereed)
    Abstract [en]

    Background: Sampling genomes with Fosmid vectors and sequencing of pooled Fosmid libraries on the Illumina platform for massive parallel sequencing is a novel and promising approach to optimizing the trade-off between sequencing costs and assembly quality. Results: In order to sequence the genome of Norway spruce, which is of great size and complexity, we developed and applied a new technology based on the massive production, sequencing, and assembly of Fosmid pools (FP). The spruce chromosomes were sampled with similar to 40,000 bp Fosmid inserts to obtain around two-fold genome coverage, in parallel with traditional whole genome shotgun sequencing (WGS) of haploid and diploid genomes. Compared to the WGS results, the contiguity and quality of the FP assemblies were high, and they allowed us to fill WGS gaps resulting from repeats, low coverage, and allelic differences. The FP contig sets were further merged with WGS data using a novel software package GAM-NGS. Conclusions: By exploiting FP technology, the first published assembly of a conifer genome was sequenced entirely with massively parallel sequencing. Here we provide a comprehensive report on the different features of the approach and the optimization of the process. We have made public the input data (FASTQ format) for the set of pools used in this study: ftp://congenie.org/congenie/Nystedt_2013/Assembly/ProcessedData/FosmidPools/.(alternatively accessible via http://congenie.org/downloads).The software used for running the assembly process is available at http://research.scilifelab.se/andrej_alexeyenko/downloads/fpools/.

    Comparative interactomics with Funcoup 2.02012In: Nucleic Acids Research, ISSN 0305-1048, E-ISSN 1362-4962, Vol. 40, no D1, p. D821-D828Article in journal (Refereed)
    Abstract [en]

    FunCoup (http://FunCoup.sbc.su.se) is a database that maintains and visualizes global gene/protein networks of functional coupling that have been constructed by Bayesian integration of diverse high-throughput data. FunCoup achieves high coverage by orthology-based integration of data sources from different model organisms and from different platforms. We here present release 2.0 in which the data sources have been updated and the methodology has been refined. It contains a new data type Genetic Interaction, and three new species: chicken, dog and zebra fish. As FunCoup extensively transfers functional coupling information between species, the new input datasets have considerably improved both coverage and quality of the networks. The number of high-confidence network links has increased dramatically. For instance, the human network has more than eight times as many links above confidence 0.5 as the previous release. FunCoup provides facilities for analysing the conservation of subnetworks in multiple species. We here explain how to do comparative interactomics on the FunCoup website.

    Global networks of functional coupling in eukaryotes from comprehensive data integration2009In: Genome Research, ISSN 1088-9051, E-ISSN 1549-5469, Vol. 19, no 6, p. 1107-16Article in journal (Refereed)
    Abstract [en]

    No single experimental method can discover all connections in the interactome. A computational approach can help by integrating data from multiple, often unrelated, proteomics and genomics pipelines. Reconstructing global networks of functional coupling (FC) faces the challenges of scale and heterogeneity--how to efficiently integrate huge amounts of diverse data from multiple organisms, yet ensuring high accuracy. We developed FunCoup, an optimized Bayesian framework, to resolve these issues. Because interactomes comprise functional coupling of many types, FunCoup annotates network edges with confidence scores in support of different kinds of interactions: physical interaction, protein complex member, metabolic, or signaling link. This capability boosted overall accuracy. On the whole, the constructed framework was comprehensively tested to optimize the overall confidence and ensure seamless, automated incorporation of new data sets of heterogeneous types. Using over 50 data sets in seven organisms and extensively transferring information between orthologs, FunCoup predicted global networks in eight eukaryotes. For the Ciona intestinalis network, only orthologous information was used, and it recovered a significant number of experimental facts. FunCoup predictions were validated on independent cancer mutation data. We show how FunCoup can be used for discovering candidate members of the Parkinson and Alzheimer pathways. Cross-species pathway conservation analysis provided further support to these observations.

    Dynamic Zebrafish Interactome Reveals Transcriptional Mechanisms of Dioxin Toxicity2010In: PLOS ONE, ISSN 1932-6203, Vol. 5, no 5, p. e10465-Article in journal (Refereed)
    Abstract [en]

    Background: In order to generate hypotheses regarding the mechanisms by which 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin) causes toxicity, we analyzed global gene expression changes in developing zebrafish embryos exposed to this potent toxicant in the context of a dynamic gene network. For this purpose, we also computationally inferred a zebrafish (Danio rerio) interactome based on orthologs and interaction data from other eukaryotes. Methodology/Principal Findings: Using novel computational tools to analyze this interactome, we distinguished between dioxin-dependent and dioxin-independent interactions between proteins, and tracked the temporal propagation of dioxin-dependent transcriptional changes from a few genes that were altered initially, to large groups of biologically coherent genes at later times. The most notable processes altered at later developmental stages were calcium and iron metabolism, embryonic morphogenesis including neuronal and retinal development, a variety of mitochondria-related functions, and generalized stress response (not including induction of antioxidant genes). Within the interactome, many of these responses were connected to cytochrome P4501A (cyp1a) as well as other genes that were dioxin-regulated one day after exposure. This suggests that cyp1a may play a key role initiating the toxic dysregulation of those processes, rather than serving simply as a passive marker of dioxin exposure, as suggested by earlier research. Conclusions/Significance: Thus, a powerful microarray experiment coupled with a flexible interactome and multi-pronged interactome tools (which are now made publicly available for microarray analysis and related work) suggest the hypothesis that dioxin, best known in fish as a potent cardioteratogen, has many other targets. Many of these types of toxicity have been observed in mammalian species and are potentially caused by alterations to cyp1a.

    Why are real interest rates so low? Evidence from a structural VAR with sign restrictionsManuscript (preprint) (Other academic)
    Abstract [en]

    Real interest rates reached record low levels in many countries as the business cycle picks up after the financial crisis. Numerous explanations for this phenomenon have been suggested, but only a handful of studies attempt to disentangle the relative importance of the different factors. Sign restrictions are useful for analyzing this problem since shocks to the supply of savings and investment demand have effects of different signs. The simplest bivariate Bayesian VAR model with only the real interest rate and savings indicates that shocks to investment have been twice as important as shocks to savings. When more variables are included, we find that negative business cycle shocks have depressed the real interest rate by -1.26%. The second most important factor is low productivity, contributing-1.11%. However, high savings has not been a major driving force behind the low real interest rates during the recent period.

    The interbank market risk premium, central bank interventions, and measures of market liquidity2014In: Journal of International Money and Finance, ISSN 0261-5606, E-ISSN 1873-0639, Vol. 48, p. 202-217Article in journal (Refereed)
    Abstract [en]

    When the interbank market risk premium soared during the financial crisis, it created a wedge between interest rates actually paid by private agents and the rapidly falling policy rates. Many central banks attempted to improve the situation by supplying liquidity to the domestic interbank market. This paper studies the Swedish interbank market risk premium using a unique data set on traded volume between banks and between banks and the Riksbank. We find that the main determinants of the Swedish interbank premium are international variables, such as US and EURO area risk premia. International exchange rate volatility and the EURO/USD deviations from CIP also matters, while standard measures of domestic market liquidity and domestic credit risk have insignificant effects. Nonlinear smooth transition (STR) models show that U.S. financial variables are more important in times of a rising U.S. risk premium. Our measure of actual turnover in the interbank market is associated with a significant reduction of the interbank market risk premium, as are credit provisions by the central bank.

    Can Endogenous Monetary Policy Explain the Deviations from UIP?2002Report (Other academic)
    Abstract [en]

    The co-movements of nominal exchange rates and short-term interest rates as the economy is hit by shocks is a potential source of ex post deviations from uncovered interest rate parity. This paper investigates whether an established model of endogenous monetary policy in an open economy is capable of explaning the exchange rate risk premium puzzle. Time series on interest differentials and exchange rate changes are generated from the Svensson (2000) model. Uncovered interest rate parity is tested on the simulated data and the b-coefficients are investigated. For most realistic choices of parameter values, the b-coefficients are positive but much smaller than the unity value expected from UIP. It is however also possible to obtain large, negative b-coefficients if the central bank is engaged in interest rate smoothing.

    Abstract [en]

    There is tentative evidence to suggest that the well-documented empirical failure of uncovered interest parity (UIP) is confined to short-term interest rates. However, tests of UIP for long-term bonds are thwarted by various data problems. These data problems can be avoided by focusing on short investments in long-term bonds. This paper concerns the relationship between changes in the US dollar-Deutsche Mark exchange rate and returns to short investments in US and German long-term government bonds. The hypothesis that expected returns to investments in bonds denominated in the two currencies are equal is not rejected, and the estimated slope coefficients are positive. For corresponding short-term interest rates, the typical finding of negative and large Fama coefficients is confirmed. We conclude that it is the maturity of the asset, rather than the investment horizon, that matters for the results.

    Stock prices and GDP in the long run2018In: Journal of Applied Finance and Banking, ISSN 1792-6580, E-ISSN 1792-6599, Vol. 8, no 4, p. 107-126Article in journal (Refereed)
    Abstract [en]

    Previous studies have documented long run equilibrium relationships between either stock prices and labour income or dividends and consumption. In a general equilibrium stochastic growth model, these variables are related in the long run because they are all driven by the same stochastic trend - the fundamental development of productivity. We show that national stock price indices are cointegrated with domestic and foreign GDP in the G7 countries. Higher domestic productivity increase both domestic GDP and domestic stock prices. In the panel, countries with favorable GDP developments also have higher stock prices. The relationship between relative GDP and relative stock prices is stronger for countries with markedly different GDP growth compared to their trading partners.

    Animal Experiment Regulations as a Part of Public Law2009In: European Public Law, ISSN 1354-3725, E-ISSN 1875-8207, Vol. 15, no 2, p. 197-205Article in journal (Refereed)
    Abstract [en]

    This article describes the Swedish rules about experiments on animals and the function of the Swedish animal ethics experimentation committees. A small survey of the rules about experiments on animals in Norway, Denmark, Finland, England and Wales, and the EU, is included. The Swedish rules on animal experimentation are examined in order to see how their form and functions relate to theories about different kinds of decision making in public law. The extents to which the rules agree with the aims of the law and with existing normative patterns are also examined. The difficulties to handle the ethical weighting between the importance of the experiment and the suffering of the animals are discussed.

    Abstract [en]

    Alexius Borgström, K. Djuren, läkarna och lagen. En rättslig studie om djurförsöksetik. Animals, doctors and the law. A study in the Swedish Regulation of Animals Scientific Procedures.

    The aim of this study was to analyse how the Swedish rules about experiments on animals and the animal ethics experimentation committees relate to different kinds of decision-making models, such as the legal-bureaucratic, the professionalistic, and the corporatist model for decision making in public law. The aim was also to study the extent to which the theoretical design of the rules about animal experimentation, on the one hand, and their practical application on the other hand, agree with the political intentions and valuestructures that exist. The study was conducted with the methods of legal dogmatism and sociology of law. The study found that the valuestructures in the law on animal experimentation consist of freedom of research, advocacy of regulation, abolitionism, species hierarchism, and general intrinsicality. In addition, it was found that ethical considerations of animal experimentation are difficult to handle, since the factors that are weighed up against each other, i.e., the importance of the experiment and the suffering of the animals, are incommensurable. The consideration of pros and cons is governed in practice by the committee members who are connected to research, since they are granted a professionally based preferential right of interpretation of biomedical claims. The study also showed that the rules about experiments on animals are not applied with full legal security and that the committees have been constituted on the basis of deliberative consensus without consideration for the fact that the balance between human and animal interests is sometimes part of a struggle over interests and opinions.

    Djurskydd som rättsligt intresse och djurplågeribrottet i Sverige2010In: Retfærd. Nordisk Juridisk Tidsskrift, ISSN 0105-1121, Vol. 33 årgång, no 4/131, p. 66-76Article in journal (Refereed)
    Abstract [en]

    In Sweden cruelty to animals can be penalized according to chapter 16, section 13 of the Penal Code (1962:700). Since the law demands the cause of the cruelty to be improperly, the crime often includes a weighting between the suffering of animals and the grounds of human behaviour that caused the suffering. The aim of this article is to study difficulties in the weighting between these factors. Methods of legal dogmatism, legal history and history of ideas are used. The article finds that suffering of animals and grounds of human behaviour often can be seen incommensurable factors, and that weighting between these factors therefore depends on the values of the person making the decision.

    JO och tjänstemännen: En laghistorisk studie2003 (ed. 500)Book (Other academic)
    Abstract [en]

    The purpose of this project is to study the Swedish Parliamentary Ombudsman Institution (JO) and its supervision of civil servants in the 20th century. Liability for misuse of office, the obedience obligation and the shaping of the principle of independence will also be considered. The study proceeds from a jurisprudential framework and is based on a legal dogmatic approach, although statistical information and other materials from the social sciences are also included. The findings of the study are as follows. The abolition of criminal liability for misuse of office in the mid-1970s resulted in a termination of the relationship which originally existed between civil servants’ authority under the principle of independence on the one hand, and their liability for service irregularities on the other. As a result, this reform entailed a pervasive change in one of the mainstays of the Swedish administrative model. The change was however of marginal importance to the activities of the JO, since a small and extraordinary office cannot effectively enforce legality and civil rights within a large public sector by initiating proceedings and demanding liability for committed errors. During the latter part of the 20th century, the JO thus evolved from having been a prosecutor who ensured that civil servants did not neglect their official duties into serving as a source of preventive guidance for government and municipal agencies. The question of how congruence is to be achieved between the civil servants’ liability for service irregularities and the powers of public authority is however, given the findings of this study, still largely unanswered.

    Prognoser i tvångsvårdsärenden om omsorgssvikt2013In: Socialvetenskaplig tidskrift, ISSN 1104-1420, Vol. 20, no 3-4, p. 186-202Article in journal (Refereed)
    Abstract [en]

    This study set out to analyze how background-context, prognoses and evidence-based facts are referred to in child welfare investigations and judgments concerning coercive care of neglected children. The texts of social investigations and court judgments in 16 cases concerning parents (30) and their children (29) in two counties in Sweden were analyzed by a hermeneutic case study. All cases concerns section 2 in The Care of Young Persons (Special Provisions) Act (1990:52), which states that coercive care shall be decided if, due to neglect or some other situations, there is a “palpable risk of detriment” to the child’s health or development. Theoretical framework of sociology of law and of normative legalism were used. The study shows that background-context, prognoses and evidence-based facts seldom are connected in the texts. Background-contexts quantitively dominates, while prognoses are vestigial and rarely enunciates as emanating from evidence-based facts. Instead of describing risk-assessments a plurality of the descriptions in the texts pictures the children as already harmed by neglect. The conclusion of the study is that the sociological conceptions of “a palpable risk” differ a great deal from the legal-theoretical interpretation of the concept.

    RÅ 2009 ref. 64: Något om tvångsvårdsbedömningar rörande ett barn till en utvecklingsstörd förälder2011In: Nordisk socialrättslig tidskrift, ISSN 2000-6500, no 3-4, p. 25-51Article in journal (Other academic)
    Abstract [en]

    In this article a precedent from the Supreme Administrative Court in Sweden is analysed (RÅ 2009 ref. 64). The case concerns an application for a care order by a local Social Welfare Authority according to section 2 inThe Care of Young Persons (Special Provisions) Act (1990:52). It regards the child of a single mother with an intellectual disability. The purpose of the article is to study the interpretation of the legal requirements of a “palpable risk of detriment” to the child’s health or development and to what degree the evaluations are based on the knowledge of risk assessment in social sciences. The study shows that there are limited possibilities to anticipate and calculate the palpable risks of detriment caused by facts of neglect, that sometimes are the consequences of intellectually incapacitated parents´ inabilities. Assessing a specific child’s social prognosis is always complex, difficult and occasionally almost impossible. Present demands of evidential value when establishing “palpable risk of detriment” to the child’s health or development are therefore unrealistic. The conclusion of the article is that the legal demand for risk evaluations in section 2 in The Care of Young Persons (Special Provisions) Act is inadequate designed. The author recommends that the words of the act are focused on the present and the past instead of the future.

    Abstract [sv]

    Vid omhändertaganden av barn ska barnets bästa vara avgörande för de beslut som fattas. I den praktiska tillämpningen innefattar begreppet ofta tolkningar av barns behov, såsom dessa definieras av kompetenta vuxna, och barnets vilja, såsom denna uttrycks av barnet eller uttolkas av vuxna. I denna studie undersöks uttrycken barns behov och vilja samt hur barns behov och vilja bedöms i sociala utredningar och domar som rör tvångsomhändertaganden till följd av omsorgssvikt av barn i familjer där någon förälder har intellektuell funktionsnedsättning.

    Care assessments concerning involuntary removal of children from intellectually disabled parents2014In: Journal of Social Welfare and Family Law, ISSN 0964-9069, E-ISSN 1469-9621, Vol. 36, no 3, p. 295-310Article in journal (Refereed)
    Abstract [en]

    This study set out to analyse how parenting and the needs of the children are assessed by social authorities and courts in families where one or both parents have an intellectual disability (ID). The texts of child welfare investigations and court judgements in 16 cases of care orders concerning parents (30) with IDs and their children (29) in two counties in Sweden were analysed by a hermeneutic case study. The study shows that even though many of the children are described as already harmed by neglect, clear assessments of care needs are not presented and it is uncertain which of the children’s needs a placement in a family home is assumed to satisfy. The conclusion of the article is that, even though no direct discrimination can be established, the particular individual and structural difficulties of the families’ life circumstances are not taken into consideration. This can be seen as a discriminatory practice.

    Assigning responsibility for gambling-related harm: scrutinizing processes of direct and indirect consumer responsibilization of gamblers in Sweden2017In: Addiction Research and Theory, ISSN 1606-6359, E-ISSN 1476-7392, Vol. 25, no 6, p. 462-475Article in journal (Refereed)
    Abstract [en]

    This study is an inquiry into how actors in the Swedish gambling industry, gambling problem prevention and support structures articulate responsibility for the problems that arise from gambling. A main point made in the study is that responsibility for the gambling-related harm is actively constructed and reproduced in a hegemonic way that situates the main responsibility for the emergence and handling of gambling-related harm on the individual gambler and that relies heavily on the individual's capacity to control and adjust his/her consumption to prevent gambling related harm. Drawing on extensive ethnographical fieldwork on responsible gambling practices in the Swedish context, the author brings attention to the often-unproblematized view of contemporary responsible gambling measures, and the need to develop a self-reflexive critical analysis of the ways in which responsibility is divided and assigned in this politicized market and wider policy field. As a conceptual contribution, an analytical distinction is suggested between measures of direct responsibilization (teaching and training gamblers to be responsible) and measures of indirect responsibilization (teaching and training intermediaries in the market, such as gambling agents and support association staff, to relinquish responsibility on behalf of the gambling consumer). The results indicate that such a distinction is fruitful for a nuanced understanding of contemporary responsibility policies and practices.

    Making up the responsible gambler: Organizing self-control education and responsible gaming equipment in the Swedish gambling market2011In:  , 2011Conference paper (Other academic)
    Abstract [en]

    Responsibilization permeates the various corners of society - not least the

    markets where responsibility is shifted down from states and organizations to individuals in their role as consumers. How then is responsibility (re)constructed and (re)distributed amongst market actors? This empirical paper contributes to our understanding of the ‘preventive turn’ in governance and more specifically the current trend towards self-control, and self-management by an analysis of consumer responsibilization at the market level. The paper is empirically based on interviews with key informants involved in attempts to organize rational, responsible consumers in the contested Swedish gambling market, a dozen participant observations of responsible gaming education (offline) and Internet studies of on-line equipment and education designed to motivate and teach gamblers to assume responsibility for gambling related problems. Drawing on a market constructionist perspective a model of responsibility in the making is presented. The paper then contributes with empirical illustrations of consumer responsibilization practices carried out in the Swedish context. Findings suggest that the responsible gambler is made up both directly and indirectly, both positively and negatively and by employment of a subtle yet powerful discourse of care.

    'The Most Regulated Deregulated Market in the World'? Sellers Organizing across Markets2018In: Organizing and Reorganizing Markets / [ed] Nils Brunsson, Mats Jutterström, Oxford: Oxford University Press, 2018Chapter in book (Refereed)
    Abstract [en]

    Markets are intertwined. If a certain market is perceived as being unorganized or inappropriately organized for neighbouring markets, sellers or buyers in those adjacent markets may step in as organizers. In this chapter, I use the case of the Swedish taxi market as it developed from around 1990 until 2015 to demonstrate how hotel companies and owners of travel terminals haveassumed organizer roles in the taxi transport market. This account is based on a qualitative analysis of three cases of participant observation and eight interviews with key stakeholders. The interviews and the first two observations were conducted in the autumn of 2013, and one additional observation was conducted in the spring of 2015. In addition, the chapter is informed by a broad base of documents: previous research, industry reports and company policies, newspaper articles, and public reports.

    Ek dr. Susanna Alexius vid Score, Stockholms universitet och Handelshögskolan i Stockholm ger sin syn på ansvarsfrågan inom bland annat spelmarknaden genom en sammanställning av det egna författarskapet i bl a boken Ansvar och marknader (Liber 2014) och ytterligare aktuell litteratur inom området. Hon lyfter här frågan om marknadens förutsättning att fördela och ge initiativ till ansvarstagande för spelmarknadens baksidor för att ge ytterligare fördjupning kring lösningen av problem inom spelmarknaden. Slutsatserna står delvis i kontrast mot ett förhärskande tankestoff om individualitet, beteendevetenskap och det egna ansvaret.
