  • Novel Processes for Architectural Optimisation of Building Materials Performance: Introducing Material Phase Transitions and Generative Life Cycle Assessments
  • Tidskriftsartikel (refereegranskat)abstract
    • Conventional phase diagrams plot differences in properties (e.g. volume) of a medium generated by changes in external conditions (e.g. temperature and/or pressure). This paper discusses how the logic of such diagrams can be applied to produce a new type of surface plot, material phase transition (MPT) diagrams, that chart not the conditions for chemical equilibrium but the relative benefits of a particular material system given a set of predefined objectives and a virtual search space of design solutions. Such diagrams can form an integral part of parametric design processes that use ‘auxiliary loads’ (e.g. LCA values) as variables to generate design iterations. A Grasshopper user object is created and used to design a box beam that yields a set of auxiliary loads charts and MPT diagrams. The anatomy of MPT diagrams is described, and areas for future studies discussed.

  • Sliding Sidewinders: Early-Stage Design of an Anticipatory Adaptive Assemblage
  • Tidskriftsartikel (refereegranskat)abstract
    • This quantitative/qualitative evaluation of meta-heuristic design processes being implemented in a real-life architecture project introduces the theoretical concept of anticipatory adaptive assemblages (AAA) and reports on tactics that were used to reduce the ‘curse of dimensionality’ associated with the mechanisms that produce such assemblages. It describes strategies to adopt ‘presilient’ methods to constrain a model’s design space before any evolutionary solving occurs, leverage the advantage in fenestration performance presumed to arise from explorations of non-periodic tessellations of the plane, and use benchmark models to optimise some material aspects of wall sections. These tactics all support a materiality-based approach to designing architecture using genetic algorithms. The experiments were designed in an attempt to begin to close the knowledge gap between on the one hand the existing praxis of LCA-based analyses, on the other simulations that use material properties to directly inform geometries associated with particular combinations of (for instance) site, weather, and material data. The hypothesis is that AAA’s can become an effective framework for design-based adaptation to site conditions and mitigation of climate change. The objectives of the study are a) to implicitly and qualitatively describe the trials and tribulations a commercial adaptation of alternative design processes may cause, while b) explicitly and quantitatively report on the results of the experiments, and how they relate to AAAs. After an introduction of the AAA concept, three design experiments are described and their outcomes analysed, followed by a concluding discussion including suggestions for future studies.

  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • I den här artikeln tar vi utgångspunkt i en omfattande kartläggning av de myndigheter som vi menar har som huvuduppgift att påverka marknader. Vi är intresserade av vad dessa myndigheter gör till vardags, inom ramen för den mer övergripande marknadsregleringen i form av konkurrenslagar, avtalslagar, konsumentköplagar och så vidare. Det ska sägas att vi inte har synat den påverkan som myndigheter har på marknader genom att själva vara (ibland dominerande) säljare eller köpare på olika marknader. Vidare intresserar vi oss endast för myndigheter vars verksamhet på ett mer direkt sätt riktas mot marknader. För varje myndighet har vi ställt tio marknadsrelaterade frågor. Svaren har vi funnit i offentligt material – som myndigheternas instruktioner, regleringsbrev, årsredovisningar, rapporter och webbsidor. Det sammanställda materialet omfattar över 300 sidor. Nedan analyserar vi svaren på några av våra mer centrala frågor.

  • Marknadsstaten : om vad den svenska staten gör med marknaderna - och marknaderna med staten
  • 2017
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • Under de senaste decennierna har många verksamheter förts över från stat och kommun till företag som agerar på marknader. Men den svenska staten är fortfarande djupt engagerad i marknaderna. Den har utvecklat en särskild marknadspolitik och en fjärdedel av de statliga myndigheterna har som huvuduppgift att organisera marknader. Samtidigt är marknadspolitiken abstrakt och svårfångad, och myndigheterna arbetar främst med mjuka och otydliga påverkansmetoder. Trots alla insatser finns det en utbredd tro på att marknader fungerar bäst om de lämnas ifred. Statens politik ger utrymme för andra att utöva makt. Genom djupstudier av olika marknader åskådliggör boken hur myndigheterna samarbetar med säljarna och hur säljarna får en stark position. Boken riktar sig till alla som är intresserade av den moderna statens omvandling: lärare och forskare vid universitet och högskolor, politiker, tjänstemän i stat och näringsliv och den samhällsintresserade medborgaren.

  • AXIAL TURBINE DESIGN FOR A TWIN-TURBINE HEAVY-DUTY TURBOCHARGER CONCEPT
  • 2018
  • Ingår i: PROCEEDINGS OF THE ASME TURBO EXPO. - : ASME Press. - 9780791851005
  • Konferensbidrag (refereegranskat)abstract
    • In the process of evaluating a parallel twin-turbine pulse-turbocharged concept, the results considering the turbine operation clearly pointed towards an axial type of turbine. The radial turbine design first analyzed was seen to suffer from sub-optimum values of flow coefficient, stage loading and blade speed-ratio. Modifying the radial turbine by both assessing the influence of "trim" and inlet tip diameter all concluded that this type of turbine is limited for the concept. Mainly, the turbine stage was experiencing high values of flow coefficient, requiring a more high flowing type of turbine. Therefore, an axial turbine stage could be feasible as this type of turbine can handle significantly higher flow rates very efficiently. Also, the design spectrum is broader as the shape of the turbine blades is not restricted by a radially fibred geometry as in the radial turbine case. In this paper, a single stage axial turbine design is presented. As most turbocharger concepts for automotive and heavy-duty applications are dominated by radial turbines, the axial turbine is an interesting option to be evaluated for pulse charged concepts. Values of crank-angle-resolved turbine and flow parameters from engine simulations are used as input to the design and subsequent analysis. The data provides a valuable insight into the fluctuating turbine operating conditions and is a necessity for matching a pulse-turbocharged system. Starting on a 1D-basis, the design process is followed through, resulting in a fully defined 3D-geometry. The 3D-design is evaluated both with respect to FEA and CFD as to confirm high performance and durability. Turbine maps were used as input to the engine simulation in order to assess this design with respect to "on-engine" conditions and to engine performance. The axial design shows clear advantages with regards to turbine parameters, efficiency and tip speed levels compared to a reference radial design. Improvement in turbine efficiency enhanced the engine performance significantly. The study concludes that the proposed single stage axial turbine stage design is viable for a pulse-turbocharged six cylinder heavy-duty engine. Taking into account both turbine performance and durability aspects, validation in engine simulations, a highly efficient engine with a practical and realizable turbocharger concept resulted.

  • Engine Optimized Turbine Design
  • 2019
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. create a desperate need for immediate action. A major contributor to the cause of these effects is the transportation sector, a sector that relies heavily on the internal combustion engine and fossil fuels. The heavy-duty segment of the transportation sector is a major consumer of oil and is responsible for a large proportion of emissions.The global community has agreed on multiple levels to reduce the effect of man-made emissions into the atmosphere. Legislation for future reductions and, ultimately, a totally fossil-free society is on the agenda for many industrialized countries and an increasing number of emerging economies.Improvements of the internal combustion engine will be of importance in order to effectively reduce emissions from the transportation sector both presently and in the future. The primary focus of these improvements is undoubtedly in the field of engine efficiency. The gas exchange system is of major importance in this respect. The inlet and exhaust flows as the cylinder is emptied and filled will significantly influence the pumping work of the engine. At the center of the gas exchange system is the turbocharger. The turbine stage of the turbocharger can utilize the energy in the exhaust flow by expanding the exhaust gases in order to power the compressor stage of the turbocharger.If turbocharger components can operate at high efficiency, it is possible to achieve high engine efficiency and low fuel consumption. Low exhaust pressure during the exhaust stroke combined with high pressure at the induction stroke results in favorable pumping work. For the process to work, a systems-based approach is required as the turbocharger is only one component of the engine and gas exchange system.In this thesis, the implications of turbocharger turbine stage design with regards to exhaust energy utilization have been extensively studied. Emphasis has been placed on the turbine stage in a systems context with regards to engine performance and the influence of exhaust system components.The most commonly used turbine stage in turbochargers, the radial turbine, is associated with inherent limitations in the context of exhaust energy utilization. Primarily, turbine stage design constraints result in low efficiency in the pulsating exhaust flow, which impairs the gas exchange process. Gas stand and numerical evaluation of the common twin scroll radial turbine stage highlighted low efficiency levels at high loadings. For a pulse-turbocharged engine with low exhaust manifold volume, the majority of extracted work by the turbine will occur at high loadings, far from the optimum efficiency point for radial turbines. In order for the relevant conditions to be assessed with regards to turbine operation, the entire exhaust pulse must be considered in detail. Averaged conditions will not capture the variability in energy content of the exhaust pulse important for exhaust energy utilization.Modification of the radial turbine stage design in order to improve performance is very difficult to achieve. Typical re-sizing with modifying tip diameter and trim are not adequate for altering turbine operation into high efficiency regions at the energetic exhaust pulse peak.The axial turbine type is an alternative as a turbocharger turbine stage for a pulse-turbocharged engine. The axial turbine stage design can allow for high utilization of exhaust energy with minimal pressure interference in the gas exchange process; a combination which has been shown to result in engine efficiency improvements compared to state-of-the-art radial turbine stages.

  • Exhaust volume dependency of turbocharger turbine design for a heavy duty otto cycle engine
  • 2017
  • Ingår i: Proceedings of the ASME Turbo Expo. - : ASME Press. - 9780791850800
  • Konferensbidrag (refereegranskat)abstract
    • This study is considering turbocharger turbine performance at "on-engine" conditions with respect to turbine design variables and exhaust manifold volume. The highly unsteady nature of the internal combustion engine will result in a very wide range of turbine operation, far from steady flow conditions. As most turbomachinery design work is conducted at steady state, the influence of the chosen turbine design variables on the crank-angle-resolved turbine performance will be of prime interest. In order to achieve high turbocharger efficiency with the greatest benefits for the engine, the turbine will need high efficiency at the energetic exhaust pressure pulse peak. The starting point for this paper is a target full load power curve for a heavy duty Otto-cycle engine, which will dictate an initial compressor and turbine match. Three radial turbine designs are investigated, differing with respect to efficiency characteristics, using a common compressor stage. The influence of the chosen turbine design variables considering a main contributor to unsteadiness, exhaust manifold volume, is evaluated using 1D engine simulation software. A discussion is held in conjunction with this regarding the efficiency potential of each turbine design and limitations of turbine types.

  • ON THE CHOICE OF TURBINE TYPE FOR A TWIN-TURBINE HEAVY-DUTY TURBOCHARGER CONCEPT
  • 2018
  • Ingår i: PROCEEDINGS OF THE ASME TURBO EXPO. - : AMER SOC MECHANICAL ENGINEERS. ; 8
  • Konferensbidrag (refereegranskat)abstract
    • In this study, a fundamental approach to the choice of turbocharger turbine for a pulse-charged heavy-duty diesel engine is presented. A standard six-cylinder engine build with a production exhaust manifold and a Twin-scroll turbocharger is used as a baseline case. The engine exhaust configuration is redesigned and evaluated in engine simulations for a pulse-charged concept consisting of a parallel twin-turbine layout. This concept will allow for pulse separation with minimized exhaust pulse interference and low exhaust manifold volume. This turbocharger concept is uncommon, as most previous studies have considered two stage systems, various multiple entry turbine stages etc. Even more rare is the fundamental aspect regarding the choice of turbine type as most manufacturers tend to focus on radial turbines, which by far dominate the turbochargers of automotive and heavy-duty applications. By characterizing the turbine operation with regards to turbine parameters for optimum performance found in literature a better understanding of the limitations of turbine types can be achieved. A compact and low volume exhaust manifold design is constructed for the turbocharger concept and the reference radial turbine map is scaled in engine simulations to a pre-set AFR-target at a low engine RPM. By obtaining crank-angle-resolved data from engine simulations, key turbine parameters are studied with regard to the engine exhaust pulse-train. At the energetic exhaust pressure pulse peak, the reference radial turbine is seen to operate with suboptimum values of Blade-Speed-Ratio, Stage Loading and Flow Coefficient. The study concludes that in order to achieve high turbine efficiency for this pulse-charged turbocharger concept, a turbine with efficiency optimum towards low Blade-Speed Ratios, high Stage Loading and high Flow Coefficient is required. An axial turbine of low degree of reaction-design could be viable in this respect.

  • Knockout of the radical scavenger α1-microglobulin in mice results in defective bikunin synthesis, endoplasmic reticulum stress and increased body weight
  • 2021
  • Ingår i: Free Radical Biology and Medicine. - : Elsevier BV. - 0891-5849. ; 162
  • Tidskriftsartikel (refereegranskat)abstract
    • α1-microglobulin (A1M) is a ubiquitous protein with reductase and radical- and heme-binding properties. The protein is mainly expressed in the liver and encoded by the α1-microglobulin-bikunin precursor (AMBP) gene together with the plasma proteinase inhibitor bikunin. The AMBP polypeptide is translated, glycosylated and the C-terminal bikunin part linked via a chondroitin sulfate glycosaminoglycan chain to one or two heavy chains in the endoplasmic reticulum (ER) and Golgi compartments. After proteolytic cleavage, the A1M protein and complexed bikunin parts are secreted separately. The complete physiological role of A1M, and the reason for the co-synthesis with bikunin, are both still unknown. The aim of this work was to develop an A1M knockout (A1M−KO) mouse model lacking expression of A1M, but with a preserved bikunin expression, and to study the phenotypic traits in these mice, with a focus on hepatic endoplasmic reticulum (ER) function. The bikunin expression was increased in the A1M−KO mouse livers, while the bikunin levels in plasma were decreased, indicating a defective biosynthesis of bikunin. The A1M−KO livers also showed an increased expression of transducers of the unfolded protein response (UPR), indicating an increased ER-stress in the livers. At twelve months of age, the A1M−KO mice also displayed an increased body weight, and an increased liver weight and lipid accumulation. Moreover, the KO mice showed an increased expression of endogenous antioxidants in the liver, but not in the kidneys. Together, these results suggest a physiological role of A1M as a regulator of the intracellular redox environment and more specifically the ER folding and posttranslational modification processes, particularly in the liver.

  • Do Employers Prefer Fathers? Evidence from a Field Experiment Testing the Gender by Parenthood Interaction Effect on Callbacks to Job Applications
  • 2017
  • Ingår i: European Sociological Review. - : OXFORD UNIV PRESS. - 0266-7215 .- 1468-2672. ; 33:3, s. 337-348
  • Tidskriftsartikel (refereegranskat)abstract
    • In research on fatherhood premiums and motherhood penalties in career-related outcomes, employers discriminatory behaviours are often argued to constitute a possible explanation for observed gender gaps. However, there is as yet no conclusive evidence of such discrimination. Utilizing a field experiment design, we test (i) whether job applicants are subject to recruitment discrimination on the basis of their gender and parenthood status, and (ii) whether discrimination by gender and parenthood is conditional on the qualifications required by the job applied for. We applied for 2,144 jobs in the Swedish labour market, randomly assigning gender and parenthood status to fictitious job applicants. Based on the rate of callbacks, we do not find that employers practise systematic recruitment discrimination on the basis of the job applicants gender or parental status, neither in relation to less qualified nor more highly qualified jobs.

  • Gender, Parenthood, Ethnicity and Discrimination in the Labor Market : Experimental Studies on Discrimination in Recruitment in Sweden
  • 2022
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This dissertation uses experimental methods to study hiring discrimination based on gender, parenthood and ethnicity in the Swedish labor market. Also, the role of recruiter gender for gender and ethnic discrimination is studied. Three of the four empirical studies (Study I, Study II and Study IV), are based on field experiment data using a correspondence testing method. This involves fictitious job applications sent to announced jobs, and the employer responses to these. Signals of applicant characteristics such as gender, parenthood status, and ethnicity are randomly assigned to the job applications whereas qualifications are held constant (within occupations). Study III is based on a laboratory experiment in which (fictious) job candidates are evaluated.Study I does not show any evidence of discrimination based on gender or parenthood, or any combination of these, in the first step of the hiring process, neither in highly nor less qualified occupations. Study II shows that male job applicants are favored by male recruiters, especially in gender-balanced occupations.Study III shows a statistically significant gender bias in job applicant ratings in favor of female applicants in a laboratory setting. This is particularly the case for female evaluators. Moreover, Study III shows no motherhood penalty in the applicant ratings.Study IV presents evidence of ethnic discrimination against foreign-named job applicants by both male and female recruiters. Further, there is evidence of gendered ethnic discrimination, i.e., male applicants with foreign-sounding names receive considerably fewer positive responses than female applicants with foreign-sounding names. While female recruiters favor foreign-named female applicants over foreign-named male applicants, particularly in highly qualified occupations, male recruiters appear to prefer foreign-named females over foreign-named males in male-dominated occupations.To summarize, the findings from this dissertation provide little support for the notion of discrimination in recruitment as an important mechanism behind gender inequalities in the Swedish labor market. However, the results indicate that discrimination in the recruitment process contributes to the labor market inequality of ethnic minorities, and of ethnic minority men in particular. Moreover, the findings suggest that recruiter gender matters for the success of male and female job candidates, and in particular for foreign-named men and women, at least in some occupational contexts.

  • Is there a rating bias of job candidates based on gender and parenthood? A laboratory experiment on hiring for an accounting job
  • 2023
  • Ingår i: Acta Sociologica. - 0001-6993 .- 1502-3869.
  • Tidskriftsartikel (refereegranskat)abstract
    • Biased practices by employers have been suggested as one possible cause for the observed gender disparities in labor market outcomes. While US-based laboratory experiments show a clear motherhood penalty in recruitment, European laboratory experiments on the topic are to our knowledge lacking. We conducted a laboratory experiment with 228 university students to study a potential gender bias in the evaluation of (fictitious) job candidates for an accounting manager position, and how recruitment decisions are made. We explore two dimensions of decision-making, that is, evaluators’ individual ratings and collectively made ratings. The results show a statistically significant gender bias in job applicant ratings in favor of female applicants. Thus, female job applicants are more often than male applicants rated as the top candidates, regardless of their parental status. Also, we find no motherhood penalty in the applicant ratings. Moreover, there is a statistically significant pro-female bias in applicant ratings made by female evaluators individually and by all-female evaluation groups.

    • Discriminatory practices by employers have been suggested as one possible cause for the observed gender disparities in labor market outcomes. While U.S.-based laboratory experiments show a clear motherhood penalty in recruitment, European laboratory experiments on the topic are lacking. The purpose of this paper is to study recruitment discrimination based on gender and parenthood in a laboratory setting in Sweden. We conducted a laboratory experiment with 228 human relations or business students enrolled at Stockholm University, i.e., potential future recruiters, to study potential gender bias in the evaluation of (fictitious) job candidates and how recruitment decisions are made. The results show a statistically significant gender bias in job applicant ratings in favor of female applicants. Thus, female job applicants are more often than male applicants rated as the top candidate, regardless of their parental status. Contrary to previous U.S.-based laboratory experiments, we find no motherhood penalty in the applicant ratings. Moreover, there is a statistically significant pro-female bias in applicant ratings made by female evaluators individually as well as all-female evaluation groups.

  • Scoring of medial arterial calcification predicts cardiovascular events and mortality after kidney transplantation
  • 2022
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 0954-6820 .- 1365-2796. ; 291:6, s. 813-823
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Progression of vascular calcification causes cardiovascular disease, which is the most common cause of death in chronic kidney failure and after kidney transplantation (KT). The prognostic impact of the extent of medial vascular calcification at KT is unknown. Methods In this prospective cohort study, we investigated the impact of medial calcification compared to a mix of intimal and medial calcification represented by coronary artery calcification (CAC score) and aortic valve calcification in 342 patients starting on kidney failure replacement therapy. The primary outcomes were cardiovascular events (CVE) and death. The median follow-up time was 6.4 years (interquartile range 3.7-9.6 years). Exposure was CAC score and arteria epigastrica medial calcification scored as none, mild, moderate, or severe by a pathologist at time of KT (n = 200). We divided the patients according to kidney failure replacement therapy during follow-up, that is, living donor KT, deceased donor KT, or dialysis. Results Moderate to severe medial calcification in the arteria epigastrica was associated with higher mortality (p = 0.001), and the hazard ratio for CVE was 3.1 (95% confidence interval [CI] 1.12-9.02, p < 0.05) compared to no or mild medial calcification. The hazard ratio for 10-year mortality in the dialysis group was 33.6 (95% CI, 10.0-113.0, p < 0.001) compared to living donor recipients, independent of Framingham risk score and prevalent CAC. Conclusion Scoring of medial calcification in the arteria epigastrica identified living donor recipients as having 3.1 times higher risk of CVE, independent of traditional risk factors. The medial calcification score could be a reliable method to identify patients with high and low risk of CVE and mortality following KT.

  • Inventory of Novel Animal Models Addressing Etiology of Preeclampsia in the Development of New Therapeutic/Intervention Opportunities.
  • 2016
  • Ingår i: American Journal of Reproductive Immunology. - : Wiley. - 1600-0897 .- 1046-7408. ; 75:3, s. 402-410
  • Forskningsöversikt (refereegranskat)abstract
    • Preeclampsia is a pregnancy-related disease afflicting 3-7% of pregnancies worldwide and leads to maternal and infant morbidity and mortality. The disease is of placental origin and is commonly described as a disease of two stages. A variety of preeclampsia animal models have been proposed, but all of them have limitations in fully recapitulating the human disease. Based on the research question at hand, different or multiple models might be suitable. Multiple animal models in combination with in vitro or ex vivo studies on human placenta together offer a synergistic platform to further our understanding of the etiology of preeclampsia and potential therapeutic interventions. The described animal models of preeclampsia divide into four categories (i) spontaneous, (ii) surgically induced, (iii) pharmacologically/substance induced, and (iv) transgenic. This review aims at providing an inventory of novel models addressing etiology of the disease and or therapeutic/intervention opportunities.

  • Att förenkla administrationen av jordbrukspolitiken - lättare sagt än gjort
  • 2008
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Sieps (Svenska institutet för europapolitiska studier) fick i juli 2007 i uppdrag av Kungl. Skogs- och Lantbruksakademien (KSLA) att utifrån en konferens på temat ”Förenkla jordbruks­politiken – lättare sagt än gjort” – arrangerat av kommittén för jordbrukets internationalisering vid KSLA den 30 maj 2007– beskriva och analysera några av de insatser och hinder som förekommer i svenska myndigheters arbete med regel­förenkling i jordbrukspolitiken.   Rapportförfattaren vill efter slutfört uppdrag lyfta fram betydelsen av att en politisk prioritering av förenklingar – i det här fallet i form av ett mål: med regelförenklingar ska jord­bruksnäringens administrativa kostnader minska med 25 procent till år 2010 (Näringsdepartementet 2007) – kräver politiska omprövningar också av den politik som ligger bakom de olika regelverken. Det regelkrångel som jordbruksnäringen upplever (LRF 2007a, Nutek 2007, NNR 2006) ska inte i huvudsak reglerna i sig eller deras tillämpning lastas för. En märkbar förändring i företagens vardag, som varit ett annat sätt att uttrycka det 25-procentiga målet (Näringsdepartementet 2007), blir verkligt kännbar, tror författaren, först efter det att man sänkt de krav som riktas mot lantbrukaren i miljö- och djurskyddslagstiftning och i ansökningar och kontroll av europeiskt jordbruksstöd.   I vilken utsträckning som större sådana omprövningar på både europeisk och nationell nivå är aktuella, är förstås svårare att spekulera i, men frågan berörs till viss del i rapporten.  Under­sökningen kretsar istället framförallt kring de svenska försöken på statlig, regional och kommunal nivå att förenkla – men då givet de just nu rådande och övergripande politiska målen med den europeiska jordbrukspolitiken. Rapporten innehåller några förslag till förenklingar, att lägga till de redan långa listor som genererats under bland annat Jordbruksverkets förenklings­projekt (Jordbruksverket 2007).   Till skillnad från många tidigare texter om administrativa kostnader är inte de av regler ”drabbade”, i det här fallet lant­brukarna, rikligt representerade. Istället ska rapporten ses som ett försök att skildra regelförenklingsproblematiken sedd ur regeringskansliets och tillsynsmyndigheternas eget perspektiv, på departement, ämbetsverk, länsstyrelse och kommun.

Redan när vi ställer frågorna på detta sätt har vi möjligen accepterat ett par premisser; att högre utbildning har ett syfte – ett mål, en egenskap, en kvalitet! – och att utbildningens närhet till detta syfte kan mätas. Dessa premisser kan förstås diskuteras. Liksom varför och med vilka konsekvenser kvalitetsbegreppet fått utrymme i politisk styrning av svensk högre utbildning. Och genom att göra utbildning till föremål för utvärdering och jämförelser, har vi inte då slagit in på en väg som slutar i likriktning och insnävad akademisk frihet? Men även om sådana diskussioner läggs åt sidan, om vi kan antas vara överens om att högre utbildning finns till för ett visst syfte, och att utbildningens resultat i relation till detta övergripande syfte kan fångas, kan vi ha vitt skilda åsikter om vilket detta syfte ska vara och hur vi bäst bedömer måluppfyllelsen. Här viks mest utrymme åt det senare: om hur kvalitet i högre utbildning utvärderas. I texten görs några korta nedslag i några andra länders sätt att utvärdera högre utbildning, men framför allt diskuteras det nuvarande svenska kvalitetsvärderingsystemets egenskaper och effekter.

  • Edu-preneurial marketing to school leaders : strategies, stories and consequenses
  • 2019
  • Ingår i: NERA 2019 Abstract Book. ; , s. 187-188
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Research topic: New actors in the field of education – ‘edu-preneurs’ – now offer a multitude of products and services to schools: digital solutions, school development models, teaching material, conferences, professional development, etc. This paper is part of a larger study, of which the purpose is to explore under what conditions, in what forms and with which consequences these ‘edu-preneurial’ actors market, sell and implement their products and services in Swedish schools. Theoretical framework: Theoretically this project learns from earlier studies concerning neoliberal governing, the marketization of school and the ongoing blurring of boundaries between public and private sectors. Methodological design: The larger study is accomplished through interviews with school leaders as well as with edupreneurial companies. In this specific paper we study what happens inside school because of edupreneurial engagement. We analyse the total amount of marketing material sent via mail and e-mail (and collected in this research study) to 12 participating school leaders during 2018-2019 and our interviews with these school leaders about the collected material. In focus of the paper are the implications for school leaders and how they experience the impact of edu-preneurial actors; what areas and tasks are outsourced, why and how the school organization is affected in terms of administration, teaching and learning. We are also interested in the strategies and marketing of the edu-preneurs themselves and what messages they want to convey to school leaders. The data is analysed from the following questions: • Quantity and distribution. What is the extent of the collected material and how is it distributed between different schools? • Stories. What does the empirical data tell us about the Swedish schoolÅLs challenges and solutions? • Themes. Is every possible school issue addressed, is there something for everyone, or is it all about one dominant theme? Expected findings: The data collection is ongoing and the results to be presented will be preliminary. We expect to have results telling us about 1) the extent and content of the marketing material sent out to school leaders by edu-preneurial actors in the Swedish context, 2) what products and services school leaders buy and under what terms and conditions, and 3) what kind of impact these external actors and solutions have, for school leaders, staff, pupils, and school practice. Relevance: Previous research has studied these questions on a policy-level. This study explores the micro-level where the operationalisation of different policies can be observed. We assert that knowledge about the micro-level help us understand the effects of outsourcing essential parts of education to external actors. As edu-prenurial engagement in education is a global phenomenon this is of importance in our Nordic context. We conclude by discussing this in terms of what counts as valid knowledge, good teaching and effective learning.

  • Inboxes and Outputs : Stories from edu-preneurial marketing to school leaders
  • 2019
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • In their Inboxes, Swedish school leaders are confronted with offers of a multitude of products and services awaiting their action: digital solutions, school development models, conferences, professional development, etc. These emails are the point of departure of this study, aiming to analyse what happens inside school because of edu-preneurial engagement. Our study is part of a larger research project aiming to explore under what conditions, in what forms and with which consequences ‘edu-preneurial’ actors market, sell and implement their products and services in Swedish schools. An underlying thesis is that external actors are part of translating educational policy as well as offering tools for implementation of these policies. While previous research has studied these questions on a policy-level (Simons, Lundahl & Serpieri 2013; Ball 2009), our study explores the micro-level where the operationalisation of policies can be observed. Theoretically this project learns from earlier studies concerning neoliberal governing (Rizvi and Lingard 2010), the marketization of school (Bunar and Ambrose 2016), and the ongoing blurring of boundaries between public and private sectors (Ball 2007). The collection of empirical data is ongoing and consists of audiotaped focus group interviews with twelve school leaders as well as all the marketing material sent via mail and e-mail to them and gathered for three weeks (for each school leader, covering the whole year together) in 2018-2019. The data is analysed from the following themes and questions: 1) Stories, themes and policy. What does the empirical data tell us about the Swedish school´s challenges and solutions? How does this story, according to school leaders, resonate with school leaders’ actual realities and with ongoing national educational policy changes? 2) Quantity and distribution. What is the extent of the collected material and how is it distributed between different schools? 3) Content, timing and motive. What products and services do the school leaders eventually buy, when and why? In this symposium we expect to present results from all three themes, all though putting an emphasis on the first one: the stories emerging from the collected marketing materials and the stories about these stories. We assert that researching the educational micro-level in this way contributes to the understanding about the effects of national policies and the impact of external actors in implementing policy. As edu-prenurial engagement in education is a global phenomenon this is of importance in our European context. References: Ball, S.J. 2007.

  • Konventioner som verktyg för offentliga myndigheter : Om vägval och följder inför Sveriges eventuella ratificering av Farokonventionen
  • 2013
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Den här rapporten är en del i Riksantikvarieämbetets pågående regeringsuppdrag att utreda förutsättningar och konsekvenser av en eventuell anslutning till den så kallade Farokonventionen (vilket är det korta namnet på ”Europarådets ramkonvention om kulturarvets värde för samhället” ). I rapporten genomförs dels en studie kring några av de organisations- och förvaltningsrelaterade effekter för svenska kulturarvs- och kulturmiljömyndigheter som ratificeringar av konventioner, och här särskilt Farokonventionen, kan innebära. Dels utförs en mindre kartläggning av de olika strategier och alternativ som står till buds i samband med ett lands signering, ratificering och implementering av en konvention. Rapporten har inte analyserat vilka eventuella författningsändringar som kan bli aktuella vid en ratificering av konventionen. Studien byggs till viss del på empiri och teori ur tidigare forskning, men framförallt av nya intervjuer och dokumentstudier. Intervjuer har genomförts med chefer och tjänstemän på flera svenska myndigheter. Om ens strävan är att redogöra för de olika strategier och alternativ Sverige, inför en eventuell ratificering, har att överväga, och undersöka några av de konsekvenser som en ratificering kan få för de offentliga kulturmiljömyndigheternas organisation och förvaltning – ja, då finns förstås flera möjliga fält och fenomen att studera. En rapport utifrån dessa rubriker – om konventioner, alternativ och konsekvenser – kunde fokusera enbart Farokonventionen och genom en närstudie av konventionens innehåll och möjliga innebörd försöka avgöra vad just denna konvention erbjuder för valmöjligheter för Sverige och vilka konsekvenser de olika valen skulle kunna få för myndigheter och övrig förvaltning. Studien skulle också kunna handla om andra länders sätt och erfarenheter av att hantera och införliva Farokonventionen i sin lagstiftning och förvaltning, och möjligen skulle dessa lärdomar ha bäring på svenska förhållanden och vara till nytta för Sveriges överväganden och kommande praktik. En tredje möjlighet vore att syna processerna utifrån den institution som skapar, utfärdar och sprider konventioner (i Farokonventionens fall Europarådet), och se på vilket sätt man genom olika ansträngningar i olika slags forum försöker generera nationell anpassning och efterlevnad, och på vilket sätt Sverige, genom sina representanter i dessa forum, försöker påverka konventionernas innehåll. Listan på alternativa studier kan förstås göras längre, och man kan tänka sig kombinationer av studier i olika länder, på olika institutioner, på olika nivåer, och med olika empiriskt fokus. Den här rapportens syften är dock framför allt att 1) ge en bild av Sveriges alternativ inför en eventuell ratificering av Farokonventionen, att 2) diskutera några av de konsekvenser som en ratificering kan få för kulturmiljömyndigheternas organisation och förvaltning, samt 3) föra en diskussion kring olika konventioners möjligheter att fungera som effektiva verktyg i myndigheters arbete för att nå de mål konventionerna eftersträvar. Farokonventionen är bara en i en lång rad av konventioner med inriktning mot kulturarv och kulturmiljö, och i rapporten kommer därför fler konventioner än Farokonventionen att diskuteras, särskilt eftersom Farokonventionen i sig har effekter på flera tidigare konventioner, och därmed också på den svenska förvaltningen på kulturarvsområdet. I studien görs en kartläggning och en bedömning av de olika strategier och alternativ som ett land har när det gäller hanterandet av konventioner. Farokonventionen är en typ av ramkonvention som saknar bindande krav, och kan betraktas som ett inriktningsdokument där viktiga mål och insatser definieras. Det finns olika sätt att nå dessa mål och det heter att varje enskilt land väljer den väg som passar dem bäst i relation till befintlig lagstiftning och den politiska situationen. Alla konventioner ger inte denna rörelsefrihet, men aktualiserar ändå olika nationella strategier och alternativ. Det spelar till exempel stor roll om konventioner tar vägen om ändrade nationella lagar och författningar eller om budskapet från politiskt håll är att ”vi följer den här konventionen, men utan författningsändringar”. Och att ratificera även en sådan konvention som man – genom sina konsekvensutredningar – funnit skäl att inte ratificera, kan vara ett viktigt symboliskt uttryck för deltagande och solidaritet, och möjligen kan denna gest vara viktigare än de eventuella oönskade effekter eller kostnader som en ratificering för med sig. Texten kommer också att innehålla ett par teoretiska reflektioner kring konventioner som verktyg för politisk förändring och standardisering. Studien hämtar här inspiration i nyinstitutionell teori om idéspridning, konvergens och staters ”invävdhet” i EU och i världen. Rimligen har vi inte än på länge sett den sista konventionen med bäring på kulturarv och kulturmiljö och förhoppningen är att denna studies fokus på strategier och konsekvenser kan skapa ett slags förberedelse inför nästa konventions entré.

  • Myndigheterna och integrationspolitiken
  • 2006
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Frågan om de statliga myndigheternas ansvar för integrationspolitikens genomförande har ägnats ett ökande politiskt intresse. Den nu 20 år gamla förordningen (1986:856) som uppmanar alla myndigheter att - bland annat - beakta samhällets etniska och kulturella mångfald när de utformar ochbedriver sin verksamhet, har inte fått tillräckligt genomslag,menar regeringen (skr. 2001/02:129). Flera rapporter och granskningar från verk, stabsmyndigheter och ombudsmän harlyft fram brister i myndigheters sätt att hantera och införliva de integrationspolitiska målen i sin verksamhet (RiR 2005:5,Integrationsverket 2006, DO 2006). Som en del i arbetet med att förtydliga de statliga myndigheternas ansvar för integrationspolitikens genomförande, gav den Integrationspolitiska kommittén i uppdrag till Score att syna några aspekter av myndigheternas syn på deras eget integrationsarbete. Med utgångspunkt i de direktiv kommittén formulerade för denna studie – men också utifrån andra perspektiv som tillkommit under studiens genomförande - har utredaren sökt svar på följande frågor: • Vilka insatser genomför myndigheterna för att nå de integrationspolitiska målen? • Vilka strukturella aspekter anser myndigheterna hindra genomförandet av integrationspolitiken? • Hur kan styrningen av myndigheterna förbättras för att öka möjligheterna att nå de integrationspolitiska målen? • Vilka åtgärder kan vidtas för att sprida kunskapen om hur olika myndigheter bör ta hänsyn till de integrationspolitiska målen?

  • Normer och strukturer i skolutveckling : strategier hos förvaltningschefer och skolledare i implementering av inkluderande lärmiljöer
  • 2015
  • Ingår i: Från idé till praxis. - : Ifous. - 9789198284119 ; , s. 17-30
  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • Den här studien identifierar och analyserar betydelsen av professionella normer och organisatoriska strukturer i skolutveckling. I fokus är framför allt förvaltningschefers och skolledares strategier för att leda, organisera och realisera skolutveckling genom förändring av just normer och strukturer. Forskningsfrågan är: Vilka professionella normer och organisatoriska strukturer driver skolutveckling? Studien intresserar sig också för de mekanismer som underlättar eller försvårar arbetet mot förändrade normer och strukturer. Studiens empiri är hämtad från förändringsprocesser på ett flertal svenska grundskolor med det gemensamma syftet att implementera inkluderande lärmiljöer. Studien bygger i huvudsak på en mängd intervjuer med olika förvaltningschefer och skolledare, genomförda vid två tillfällen, dels i form av gruppintervjuer (i början av ett kommunövergripande och treårigt skolutvecklingsprojekt för implementering av inkluderande lärmiljöer), dels i form av individuella intervjuer (i slutet av detta projekt). Men studien har också haft tillgång till intervjuer genomförda med projektets så kallade inkluderingskoordinatorer på förvaltningsnivå, samt med särskilt ansvariga pedagoger och specialpedagoger på de deltagande skolorna, liksom till de analyser av förändringsprocesserna som de deltagande skolorna själva genomfört. Studiens resultat pekar mot att normer och strukturer kan förändras och främja skolutveckling när förvaltningschefer, skolledare och pedagoger har en gemensam vision (som kan bära reformarbetet, med klara syften och mål; ett gemensamt kognitivt paraply (med gemensamma definitioner av vad inkludering och inkluderande lärmiljöer kan vara); ett delat och delegerat ledarskap (med deltagande och inflytande från både pedagoger och elever); samt en organisatorisk struktur (som organiserar, administrerar och skapar arenor för dialog). Kunskap hos förvaltningschefer och skolledare om vilka normer och strukturer som underlättar eller försvårar skolutveckling – och redskap för att förändra normer och strukturer – är enligt denna studie en viktig faktor för framgångsrik skolutveckling.

  • Ingår i: Statsvetenskaplig Tidskrift. - Lund : Fahlbeckska stiftelsen. - 0039-0747. ; 110:4, s. 335-351
  • Tidskriftsartikel (refereegranskat)abstract
    • The professional communicators inside the Swedish Government Offices are today 140 (compared to a single one 40 years ago and just twenty 15 years ago), giving support to the idea that the media now has a major impact on everyday business inside the Government. This article shows that this partly true, as the media mainly have an effect on the politicians, the partisan ministerial staff and the communicators. But the relationship between the Government Offices and the media could also be turned around. The Government have resources for external communication no lesser than an international news agency’s, and does on a daily basis deliver an impressive amount of press releases and conferences – and information leaks – that the media has to handle. This article examines and analyses how the Swedish Government Offices, trough new posts, units and strategies, has institutionalised and centralised its’ media contacts during the last 40 years, as well as the reasons and the internal consequences of this development.

  • Striderna i Rosenbad : Om trettio års försök att förändra Regeringskansliet
  • 2007
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This dissertation examines the last thirty years of internal reforms in the Swedish Government Offices. Analysis of the evolution of personnel politics, the formation of one agency and the attempts to introduce a collective activity planning model, show that the immediate problems of the early 1970’s – an over dimensioned staff, territory battles and unclear division of responsibility for personnel and organisation – remains to this day, notwithstanding the many reforms to approach them. One principal explanation behind this is that the key players for successful reorganisations – the politicians – do hardly ever partake. Instead, and on the basis of the perspective of bureaucratic politics, this dissertation demonstrates that the internal development of the Government Offices should be explained as the result of struggles between different bureaucratic actors, with diverse views on problems and their solutions, and with various prospects and strengths to affect the outcome. Due to the choice of politicians to leave this policy field open to bureaucratic politics, the policy is essentially shaped and decided within a bureaucratic context. The dissertation ends in a conclusion that there is an almost constant bureaucratic battle behind internal organisation of the Government Offices, a conflict where tradition, values and strong bureaucratic actors play an important part, and where institutional change is exceptional, since the preserving powers in these processes have the upper hand. But politicians can change – in spite of these traditions, values and bureaucratic agents – if they have the determination. The theoretical aim of this dissertation, through a critical assessment of the bureaucratic politics perspective – an evaluation motivated by the empirical data and inspired by two challenging and related theoretic models; sociological and historical institutionalism – is to display the qualities and shortcomings of the bureaucratic politics model, to develop and improve the original model of bureaucratic politics, and making it more expedient for future studies of institutional change in central political organisations.

  • Styrningsförsök och återkoppling : En studie av tio myndigheters instruktioner, regleringsbrev och årsredovisningar över tid
  • 2014
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Givet alla dessa möjliga fenomen att studera för att få grepp om ”hur staten styr sina myndigheter” blir det uppenbart att instruktioner, regleringsbrev och årsredovisningar bara är några pusselbitar. Men dessa kan ändå sägas utgöra ett slags koncentrat av regeringens försök att styra och myndigheternas försök att följa denna styrning. I denna text finns därför dels jämförelser – av bland annat innehåll, prioriteringar, språk, framställning och layout – mellan ett urval av tio olika myndigheters instruktioner, regleringsbrev och årsredovisningar från 2003 och fram till idag, dels ett försök till analys och förklaringar av skillnader och likheter mellan dokumenten från då och nu.

  • Tillitsbaserad granskning : Om Skolinspektionens potentiella roll för skolutveckling
  • 2018
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • I den här studien följs en försöksverksamhet på Skolinspektionen, kallad regelbunden kvalitetsgranskning, i vilken myndigheten kompletterar den regelbundna tillsynens avvikelserapportering – om skolorna uppfyller författningarnas krav eller inte – med en mer formativ granskning av skolornas utbildningskvalitet och utvecklingsförmåga inom de fyra områden man granskar: undervisning, rektors ledarskap, trygghet och studiero, samt bedömning och betyg Utifrån en analys av den här studiens empiri, grundad på dokument och intervjuer på utbildningsdepartementet, Skolinspektionen och några av de skolor som granskats i försöket, tycks regelbunden kvalitetsgranskning vara kvalitetsdrivande, särskilt för de skolor som inte nått upp till ”god kvalitet” enligt Skolinspektionens bedömning. I studien ställs dock inte bara frågan om denna form av granskning av skola är kvalitetsdrivande, utan också frågor om hur granskning av skola kan bli mer kvalitetsdrivande, mindre administrativt belastande och mer tillitsbaserad (i bemärkelsen bygga på ett större förtroende för de granskades kompetens, kunskap och erfarenhet). Ett resultat av min studie är att regelbunden kvalitetsgranskning i den form som nu testats är kvalitetsdrivande, särskilt för vissa skolor, men till förfång för en mer tillitsbaserad och mindre administrativt belastande granskning. I rapporten lämnas därför några förslag på hur den regelbundna kvalitetsgranskningen skulle kunna utvecklas, om syftet vore att göra den mer kvalitetsdrivande, mindre administrativt belastande och mer tillitsbaserad.

  • To lead and coordinate school development towards inclusive learning environments : changes in school culture, professional norms and practice
  • 2017
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • This paper elaborates on school leaders’ strategies in efforts to change school culture and teachers’ professional norms. The point of departure is the opportunities and obstacles that emerged in a large-scale program (with over thirty participating schools in twelve different municipalities) for the implementation of inclusive learning environments. The paper has an organisation-cultural theoretical approach, focusing on how to change teachers’ practices through the change of school culture and teachers’ professional norms. The empirical data has been collected through several recurrent interviews with principals at school levels (in as many as 31 schools), as well as coordinators and executives at the administrative levels (in 12 different municipalities). The results stress the importance of a shared and delegated leadership between different levels and units. Successful implementation rests on the participation of many, the possibilities to influence the processes, and shared responsibility between school leaders, educators – and pupils. As the study shows, this is not progressions or practices that can be forced through binding rules or new formulations in policy documents. The change in professional norms – a prerequisite for changes in pedagogical practises enabling inclusion – must grow from below, using the impetus, inspiration and legitimacy from the levels of principals, but where renewed practice should find its forms through a shared, delegated and collegial leadership.

  • Ingår i: American Journal of Otology. - 0192-9763. ; 9:1, s. 56-59
  • Tidskriftsartikel (refereegranskat)abstract
    • Some patients with hearing impairment cannot use conventional hearing aids. One solution for these patients is the use of bone conduction hearing aids; however, this kind of equipment is associated with several problems related to the necessity for a good contact between the transducer and the temporal bone. Direct bone contact would be an ideal solution provided that safe and reaction-free skin penetration and a safe and permanent bone anchorage could be achieved. Branemark et al have developed a procedure to furnish edentulous patients with fixed bridges using titanium implants. This report is focused on the clinical status of the soft tissue adjacent to the 67 skin-penetrating devices in 60 patients. The patients have been followed between 3 and 96 months on 313 occasions, which represents a total observation time of 1515 months of clinical performance. Only one implant was extracted due to adverse skin reaction, giving a failure rate of 0.07% per month. This is comparable with the failure rate of cardiac pacemakers 0.02-0.04% per month).

  • Edu-preneurs in the welfare state. On how commercial actors make themselves indispensable through defining problems and offering solutions
  • 2018
  • Ingår i: NERA abstract book. ; , s. 480-480
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Research topic/aim: According to current debates, Swedish schools are experiencing severe problems: decreasing results in international large-scale assessments, increasing segregation, and not preparing students for job markets. This discourse has enabled an apparatus of commercial actors, ‘edu-preneurs’, offering solutions. This paper explores what happens when governing and practicing of education becomes distributed on commercial actors. The aim is to shed light on how educational policy is moved, translated, and fixed in entanglements of public and private rationalities and what this means for understandings of knowledge, teaching, and learning. Theoretical framework: We understand this growing apparatus of edu-preneurs as a result of that a shift in the responsibility of Swedish schooling is taking place (Ball, 2009). ‘Statework’, in terms of educational governance, is now carried out through an assemblage of public and private actors. This shift is understood in a historical context of neoliberalism. With Ball’s (2009) words we can call it a ‘recalibration of the state’, through which the organization of public institutions has changed – but also the meanings and practices of schooling as well as possible subjectivities for teachers and students. Methodological design: Empirically, the paper illuminates what we call the public/private statework through entering three different policy fields: research-based education, digitalization, and entrepreneurship. The data consist of a nethographical mapping of edu-preneurial companies and a close-up analysis of how three companies make themselves up as normalized educational actors. The analysis employs actor-network theory to explore of how the idea of schooling is constructed on the edu-preneurs’ websites through, formulating problems and solutions and enrolling a range of actors into the governing and practices of education. Findings and conclusions: The edu-preneurs made up themselves as taken for granted as actors, first, as defining problems: the Swedish school system is in crisis and in need for help. This is done through explicitly relating to a narrative of teaching as outdated, educational research as ‘fuzzy’ and unpractical, and schools distanced from ‘reality’ and the labour market. In the companies’ solution to this problem, they become important actors through talking about structured work, practical solutions, and modern (digital) ways of teaching. They enrol ‘friends’ into the assemblage in the shapes of education superstars, partner companies, technological devices, and policy bodies. We suggest that the companies translate the idea of schooling and carry with them epistemic implications, as well as a cultivation of desirable subjectivities. Understandings of what is useful ‘research’ as well as ‘important knowledge’ are claimed and limited. Teacher subjectivity is characterized as flexible and effective and the student subjectivity as entrepreneurial. The ideas of what knowledge is, and how teaching and learning should ‘happen’, privilege ‘business-like’ methods. Relevance to Nordic educational research: The Swedish case is interesting in a wider Nordic context since it sheds light on on-going processes in the Nordic countries through which the welfare state is transformed into a market.

  • Doing democracy. Research Perspectives on Risks and Responsibilities within a Marketised Education. PART 1
  • 2019
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Description of the symposium A general aim for school systems around the world is to prepare future citizens to participate in and contribute to society. In most western countries, this is upheld and developed within notions and practices of democracy and citizenship. Consequently, there is a close relationship between education and democracy. In times of increased global movements and diversity among students, issues of democracy therefore gain further attention, becoming a high-stake concept, recently seen in for example the new OECD framework on Global competence. At the same time, marketisation and privatisation of education rapidly change the foundations of schooling (Ball, 2009; Rizvi, & Lingard, 2010). This could be understood as parts of global transformations and trends that in many cases are supported by neoliberal visions, visions that reshape educational systems (Beach, 2010; Popkewitz, 2008). This rearrangement influences all parts of schooling and creates consequences on many levels. To name a few, the rearrangement involves profitable businesses, competitive and governing structures, digitalisation, rearranging of decision-making and responsibility, and renegotiation of discourses, positions and processes (Ball, 2009; Bunar, & Ambrose, 2016; Dovemark & Erixon Arreman, 2017; Verger, Lubienski, & Steiner-Khamsi, 2016). Furthermore, new ways of acting and communicating can be seen when policy actors, private companies, NGOs, school leaders, researchers, and lobby groups collaborate in entangled networks resulting in blurring boundaries and interwoven practices (Ball, 2018; Simons, Lundahl, & Serpieri, 2013). This in turn impacts on accountability, risk-taking, responsibility and transparency. Thus, educational spaces become fundamentally transformed and issues of democracy, societal problems, citizenship, accessibility and the like need to be renegotiated in relation to a changed educational landscape. This symposium will illuminate and discuss these changes and their consequences. For example, what happens with decision-making processes, accessibility, diversity, and political actions? What logics becomes changed, manifested or inscribed? What can be marketed, and becomes possible to sell? Could one say that citizenship and democracy have become commodities, something to trade? These questions will be addressed at the symposium alongside the discussion of the role of educational research. We stress that researchers’ engagement in education are of great importance in our European context and have the possibility to affect schools, national and international policy-makers, so called edu-preneurs and all actors involved in education. The symposium consists of contributions representing a wide range of perspectives and approaches taken by researchers from Sweden, Finland, Norway, New Zealand, and Brazil. Consequently, the symposium will mirror a variety of national and educational contexts all with the dual focus on the theme of the symposium and the theme of the conference. Many of the researchers in the symposium belong to a newly formed network called Researchers on education and marketization (the REM network) founded within the Swedish research project Education Inc. The network now consists of nineteen researchers from three countries and eight universities that in different ways problematise and scrutinise marketisation and education and the urgent and necessary issues that evolves in when education becomes marketised and new logics change the conditions for schooling. The symposium has two parts. The first part starts with an introduction given by Anna Jobér, coordinator and co-founder of the REM network followed by presentation of six papers in two sessions. They are arranged in order to give a thought-proving and interesting symposium regarding the variety of research project, methodological and theoretical perspectives as well as cultural contexts. Finally, the symposium is wrapped up by a discussant, Professor Marie Brennan https://www.vu.edu.au/contact-us/marie-brennan.

  • Good Intentions and Altruistic Objectives : Observing ‘Edu-preneurs’ at a School Fair
  • 2018
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Background: As an answer to a discourse on a Swedish school in crisis a large edu-political apparatus has been implemented. Arguments on e.g. decreasing results, segregation, and equal opportunities has reinforced a number of actors to enter the educational field – actors here called “edu-preneurs” (Rönnberg, 2017). The actors offer a multitude of products and services and essential parts of everyday schooling thus become outsourced on external actors using education as an arena to reach the core of the society – the children. This process, nurtured by political reforms such as the possibility to profit on public funds (Jober, submitted) has “re-calibrated” the Swedish school – from a government-dominated and unified educational system to an unruly free market (Ball, 2009; Hamilton, 2011). This market and its edu-preneurs will be investigated in the project ‘Education Inc.’, funded by the Swedish Research Council (Ideland, Axelsson, Jobér & Serder, 2016). The project aims to study how private actors and logics change the conditions for what counts as good education. Three forms of commodification of education, outlined by Molnar (2006), will be studied: (1) actors selling to schools; (2) actors selling in schools; and (3) actors buying for schools. In order to create a baseline for the Education Inc. project this paper describes one the first sub studies. This sub study aims to scrutinise foremost actors selling toschool when presenting themselves and engage with the school community at a school fair. Research Questions: The overarching aims of the Education Inc. project is to study under what conditions, in what forms and with which consequences ‘edu-preneurial’ actors engage in Swedish schools. This particular sub study focus on with what objectives do edu-preneurial companies, NGOs and their employees engage in Swedish school. Objectives: The aim of this sub study is to conceptualise and analyse processes on how good intentions and altruistic objectives are used as arguments to justify actors’ place in education. An earlier pre-study (Jobér, submitted) showed that tutoring companies, actors in the educational market, used arguments regarding children with special needs to justify their presence and actions. This pre-study raised a number of questions: Will the companies, whatever good intentions, overlook profit? Are arguments regarding children with special needs used as a lever for businesses to survive and profit rather than to help? Similar has been showed elsewhere (Dovemark & Erixon Arreman, 2017), therefore we claim there is a risk that actors in the educational market will not consider all children as profitable enough. There is therefore a need to scrutinize if money spent (through public funds) will increase profits and exclusion rather than to support inclusion, and in addition, if students with low exchange value fit into a neoliberal market. Theoretical framework: We argue that processes in Sweden, which is a traditionally strong and well-trusted welfare state, have become entangled with neoliberal rationalities (see e.g. Dahlstedt, 2009) and that ways of imagine and practice schooling today are shaped by neoliberal logics (Rizvi & Lingard, 2010). The neoliberal state has opened up for a commodification of education (Steiner-Khamsi, 2016) and educational reforms become a way to make up a specific kind of subjectivity (Ong, 2007). The marketization of education is thus not only about earning money, but also about making up meanings and practices of schooling and a certain kind of ideal citizen (Olmedo, Bailey & Ball 2013). This is what Ong (2007) conceptualizes as a neoliberalism which concerns how possible and desirable subjectivities are produced. The questions are what kind of objectives the actors put forward and how this correspond with what kind of desirable subjects that are produced in this neoliberal logic. Method: The sub study presented here will take a closer look at the actors selling to school when they attend a large school fair, SETT, which will take place in Sweden in April. In a pre-study to the larger ‘Education Inc.’ project this kind of educational ‘trade fairs’ has been identified as one of the spaces where policy becomes translated and turned into business ideas (Ideland et al, 2006). Observations will take place at this fair by four researchers. The observations will be written down using an observation scheme. The observations will also include photographs of the showcases and the messages that can be found there. In addition the research team will gather advertisement such as flyers and follow ongoing twitter flows. These data will be reflected on within the research group and finally analysed employing an analytical framework developed from the work by Callon (1986, used by, e.g., Hamilton 2011). The aim with this analysis is to more carefully explore how a problem is articulated through the actors and their relationships i.e. the problematisation moment in Callons work (1986). Callon proposes that translation of actions and actors analytically can be studied as four different moments: Problematization, Interessement, Enrolment, and Mobilization. It is the first step, the problematization moment and how a problem is articulated through the actors and their relationship that is in focus here. The problematization is the moment when actors (such as those the selling to schools at the school fair) or clusters of actors articulate a problem. It often involves a focus on a particular goal or a problem to be solved where the actors locate themselves as gatekeepers and problem solvers. Within the problematisation moment, the analysis can show what problems actors enhance (for example, in schools or in society), how do they want to solve these problems, and the argument that makes them indispensable to the problem and action. With this framework we can thus scrutinise with what kind of intentions and objectives these actors engage in Swedish school. Expected Outcomes: The hypothesis is that the observations conducted at this school fair and its following analyses will give insights in with what objectives and intention edu-preneurial companies, NGOs and their employees engage in Swedish school. Building on a pre-study (Jobér, submitted) and earlier research (e.g. Dovemark & Erixon Arreman) the hypothesis is also that the actors will bring forward a number of altruistic arguments. These might regard supporting the society to decrease widening socioeconomic gaps, including children with special needs, opening possibilities to equal opportunities for all, and reaching out to students living in rural areas of Sweden. However, as shown in above earlier studies, these are complicated arguments, given for example that a number of initiatives in the educational market, such as private tutoring, is not used at all by those with low incomes (Björkman, 2014, 21 November). There are reasons to believe that the expected outcomes from this pre-study not only will show what kind of altruistic objectives the actors use to justify their presence but also bring forward initial data that in forthcoming studies can be used to identify if the actors in educational market desire profits rather than inclusion and equal opportunities for all.

  • CRISPR/Cas9-based therapies and the role of astrocytes in Alzheimer’s disease and Parkinson’s disease
  • 2022
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders. Whereas the AD brain features plaques of amyloid-beta (Aβ) and neurofibrillary tangles of tau, the PD brain is characterized by Lewy bodies and Lewy neurites containing α-synuclein (αSyn). Rare familial disease forms have illustrated a central involvement of these proteins in the respective pathogeneses. Mutations in the genes for the presenilins (PSEN1, PSEN2) result in AD by an increased generation of the more aggregation prone Aβ42 peptide, whereas mutations in the αSyn gene (SNCA) cause PD by affecting aggregation of αSyn.This thesis has investigated the gene editing tool CRISPR/Cas9 as a potential treatment strategy against AD and PD. When targeting PSEN1 M146L in patient fibroblasts, the increased Aβ42/Aβ40 ratio was partially restored and the treatment typically normalized the mutation-induced conformation of presenilin 1. Moreover, the treatment did not cause any major off-target effects across the genome. For SNCA, both the wild-type form and the A53T mutant were targeted. Lentivirus-mediated delivery of CRISPR/Cas9 to patient fibroblasts and HEK293T cells led to a targeting efficiency of up to 87%. However, treatment of A53T mutant patient fibroblasts only resulted in low and inconsistent targeting efficiencies.During the course of AD, progressive cellular dysfunction and degeneration cause widespread neuronal death. Apart from neurons, also glial cells are affected by the disease process. Astrocytes, the most abundant glial cell type, play a key role in maintaining brain homeostasis. However, in a neurodegenerative environment, astrocytes enter a reactive and inflammatory state that can potentially harm nearby neurons.To further investigate the role of astrocytes in AD, we generated a co-culture system of human induced pluripotent stem cell-derived neurons and astrocytes. We observed a differential effect of direct and remote astrocytic control on neuronal viability and functionality. Physical astrocytic contact combined with the presence of Aβ resulted in increased phagocytosis and clearance of dead cells as well as a reduced neuronal activity. However, indirect contact via conditioned media from control astrocytes improved the viability of neurons, whereas addition of Aβ led to hyperactivity. Analyses of long-term astrocytic cultures revealed a persistent reactive state accompanied by a limited Aβ degradation capacity and severe cellular stress.Overall, this thesis has explored novel gene therapeutic strategies for AD and PD as well as contributed with knowledge regarding the role of astrocytes in AD progression.

    • Presenilin 1 (PS1) is a central component of γ-secretase, an enzymatic complex involved in the generation of the amyloid-β (Aβ) peptide that deposits as plaques in the Alzheimer’s disease (AD) brain. The M146L mutation in the PS1 gene (PSEN1) leads to an autosomal dominant form of early-onset AD by promoting a relative increase in the generation of the more aggregation-prone Aβ42. This change is evident not only in the brain but also in peripheral cells of mutation carriers. In this study we used the CRISPR-Cas9 system from Streptococcus pyogenes to selectively disrupt the PSEN1M146L allele in human fibroblasts. A disruption of more than 50% of mutant alleles was observed in all CRISPR-Cas9-treated samples, resulting in reduced extracellular Aβ42/40 ratios. Fluorescence resonance energy transfer-based conformation and western blot analyses indicated that CRISPR-Cas9 treatment also affects the overall PS1 conformation and reduces PS1 levels. Moreover, our guide RNA did not lead to any detectable editing at the highest-ranking candidate off-target sites identified by ONE-seq and CIRCLE-seq. Overall, our data support the effectiveness of CRISPR-Cas9 in selectively targeting the PSEN1M146L allele and counteracting the AD-associated phenotype. We believe that this system could be developed into a therapeutic strategy for patients with this and other dominant mutations leading to early-onset AD.

  • Controlling the rate of posolyte degradation in all-quinone aqueous organic redox flow batteries by sulfonated nanocellulose based membranes: The role of crossover and Michael addition
  • 2024
  • Ingår i: Journal of Energy Storage. - : Elsevier BV. - 2352-152X .- 2352-1538. ; 83
  • Tidskriftsartikel (refereegranskat)abstract
    • Aqueous organic redox flow battery (AORFB) is a technological route towards the large-scale sustainable energy storage. However, several factors need to be controlled to maintain the AORFB performance. Prevention of posolyte and negolyte cross-contamination in asymmetric AORFBs, one of the main causes of capacity decay, relies on their membranes' ability to prevent migration of the redox-active species between the two electrolytes. The barrier properties are often traded for a reduction in ionic conductivity which is crucial to enable the device operation. Another factor greatly affecting quinone-based AORFBs is the Michael addition reaction (MAR) on the charged posolyte, quinone, which has been identified as a major reason for all-quinone AORFBs performance deterioration. Herein, we investigate deterioration scenarios of an all-quinone AORFB using both experimental and computational methods. The study includes a series of membranes based on sulfonated cellulose nanofibrils and different membrane modifications. The layer-by-layer (LbL) surface modifications, i.e. the incorporation of inorganic materials and the reduction of the pore size of the sulfonated cellulose membranes, were all viable routes to reduce the passive diffusion permeability of membranes which correlated to an increased cycling stability of the battery. The kinetics of MAR on quinone was detected using NMR and its impact on the performance fading was modeled computationally. The localization of MAR close to the membrane, which can be assigned to the surface reactivity, affects the diffusion of MAR reagent and the deterioration dynamics of the present all-quinone AORFB.

    • The drawbacks of current state-of-the-art selective membranes, such as poor barrier properties, high cost, and poor recyclability, limit the large-scale deployment of electrochemical energy devices such as redox flow batteries (RFBs) and fuel cells. In recent years, cellulosic nanomaterials have been proposed as a low-cost and green raw material for such membranes, but their performance in RFBs and fuel cells is typically poorer than that of the sulfonated fluoropolymer ionomer membranes such as Nafion. Herein, sulfonated cellulose nanofibrils densely cross-linked to form a compact sulfonated cellulose membrane with limited swelling and good stability in water are used. The membranes possess low porosity and excellent ionic transport properties. A model aqueous organic redox flow battery (AORFB) with alizarin red S as negolyte and tiron as posolyte is assembled with the sulfonated cellulose membrane. The performance of the nanocellulose-based battery is superior in terms of cyclability in comparison to that displayed by the battery assembled with commercially available Nafion 115 due to the mitigation of crossover of the redox-active components. This finding paves the way to new green organic materials for fully sustainable AORFB solutions.

  • Sulfonated Cellulose Membranes: Physicochemical Properties and Ionic Transport versus Degree of Sulfonation
  • 2022
  • Ingår i: Advanced Sustainable Systems. - : Wiley. - 2366-7486. ; 6:11
  • Tidskriftsartikel (refereegranskat)abstract
    • The next generation of green ion selective membranes is foreseen to be based on cellulosic nanomaterials with controllable properties. The introduction of ionic groups into the cellulose structure via chemical modification is one strategy to obtain desired functionalities. In this work, bleached softwood fibers are oxidatively sulfonated and thereafter homogenized to liberate the cellulose nanofibrils (CNFs) from the fiber walls. The liberated CNFs are subsequently used to prepare and characterize novel cellulose membranes. It is found that the degree of sulfonation collectively affects several important properties of the membranes via the density of fixed charged groups on the surfaces of the CNFs, in particular the membrane morphology, water uptake and swelling, and correspondingly the ionic transport. Both ionic conductivity and cation transport increase with the increased level of sulfonation of the starting material. Thus, it is shown that the chemical modification of the CNFs can be used as a tool for precise and rational design of green ion selective membranes that can replace expensive conventional fluorinated ionomer membranes.
