    Klassidentitet vid seklets slut1999In: Sociologisk forskning, ISSN 0038-0342, Vol. 35, no 1, 121-139 p.Article in journal (Refereed)
    Abstract [sv]

    Class identity at the end of the century

    There has been a long term decline in working class identity in Sweden since the fifties, but now, in the late nineties, there has been a strong shift upwards. This can be seen in two Swedish survey data sets from 1993 and 1997. Data also show a widening gap between classes regarding class identity and other class related beliefs and opinions. These findings can be interpreted as an increasing class polarization concerning ideological orientations. Former strong associations between class and such orientations have become even stronger. Class voting has weakened in absolute terms (i.e. using the Alford index) when comparing the working and middle classes. However, if you control for class identity there is a remarkably strong class voting tendency when using odds ratios as a measure of relative class voting. Class voting is also highly dependent on class origin. Workers with working class origin and working class identity have a very pronounced tendency to support socialist parties compared to their middle class opposites. Such a comparison gives an unusually high score on the Alford index. The idea of ”the death of class” can find no support in these findings, on the contrary the class society seems to hold a real firm grasp of its citizens.

    Welfare regimes and welfare opinions - a comparison of eight western countries

    The article compares attitudes towards welfare state intervention in eight Western nations, using data from the 1996 module of the International Social Survey Program. Countries are chosen to represent four ”twin pairs”, approximating four ”welfare regimes”: the social democratic (Norway/Sweden), the conservative (Germany/France), the radical (Australia/ New Zealand), and the liberal (Canada/US). The empirical analysis assesses whether levels and group differences in attitudes are structured in a way that reflect distinctions between welfare regimes. It is concluded that while important differences are found between countries, both with regard to aggregated attitudes and with respect to patterns of group differences, these differences only to a limited extent reflect distinctions between welfare regimes. It is suggested that comparative attitude research should pay more attention to how general patterns of conflict, based in the division of labour, are modified by nationally specific institutions.

    Robin Hood, Matteus or strict equality. A comparative study of welfare state institutions and strategies to decrease inequality and poverty in the rich industrialized countries.

    How can we best reduce poverty and inequality? The debate on this question has raised other controversial issues: Should social policies be targeted to low-income groups or universal? Should benefits be equal for all or earnings-related? To answer these questions it is necessary to make three policy-relevant considerations: Firstly, the size of redistributive budgets is not fixed but reflects the structure of welfare state institutions. Secondly, there tends to be a tradeoff between the degree of low income targeting and the size of redistributive budgets. Thirdly, outcomes of market-based distribution are often even more unequal than those of earnings-related social insurance programs. However, traditional arguments in favor of targeting and flat-rate benefits, focusing on the distribution of the money actually transferred, have neglected these considerations. We argue that the design of social insurance institutions is of central importance for redistributive outcomes precisely because it affects the size of redistributive budgets, the tradeoff between targeting and budget size, and the public/private mix of benefit provisions. Our comparative analyses of the effects of different institutional types of welfare states on poverty and inequality are based on new data. The results indicate that institutional differences lead to unexpected outcomes and generate the paradox of redistribution: The more we target benefits at the poor and the more concerned we are with creating equality via equal public transfers to all, the less likely we are to reduce poverty and inequality.

    Abstract [sv]

    Not from love alone. Power and the division of housework.

    A recent Swedish study by Ahrne & Roman (1997) shows that married and cohabiting women often feel discontent with their male partner's contribution to housework, while married and cohabiting men commonly feel quite satisfied with the gendered division of housework. This indicates that spouses have different interests and preferences when negotiating the division of housework. The study also indicates that conflicts are frequent in households where the male partner's share of the housework is small or insignificant. The present article starts analysing such conflicts by applying an episodic concept of power, the argument being that men's satisfaction and women's discontent with a gendered division of housework, implies male domination. Bringing the concept of ”gender order” into the analysis, it goes on to maintain that male marital power is best explained by men's greater access to economic and normative resources. Finally, it is argued that high levels of conflicts between spouses, while signs of male domination, also indicate the weakening of male power. Female economic independence, together with declining male authority, has created a situation of relative deprivation for women, i.e. increasing aspirations for equality, in a situation where most women still do the main part of housework. This situation explains not only high levels of conflicts between spouses, but also points to changing gender relations.

    Changing forms of care work: New class distinctions and old gender patterns in care for the elderly

    Comparative welfare state research has only recently broadened the sphere of interest from income transfers to include social care services as well; i.e., to consider the welfare state not only as a social insurance state but also as a social service state. In the article a typology of care work is suggested and used as a tool to analyse changes in the provision and financing of care for the elderly in Sweden in the 90s. Publicly financed care work, such as the municipal home-help services equally distributed among all socio-economic groups, has declined. The decrease in coverage is related both to stricter need assessments and to reduced demands due to raised user fees and changes in the content and organisation of the services; i.e. both exclusion and exit. At the same time, unpaid family care as well as care purchased on the market and paid entirely by the elderly themselves seem to be increasing. These boundary shifts lead to an increased class-related dualisation of cares ystems - an informalisation of care for less well-off groups and a marketisation for those better-off. These changes are effects of changing practice rather than explicit policy changes, and can be seen as signs of a creeping selectivisation of the universal welfare system.

    Final COMPASS results on the deuteron spin-dependent structure function g(1)(d) and the Bjorken sum rule2017In: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 769, 34-41 p.Article in journal (Refereed)
    Abstract [en]

    Final results are presented from the inclusive measurement of deep-inelastic polarised-muon scattering on longitudinally polarised deuterons using a (LiD)-Li-6 target. The data were taken at 160 GeV beam energy and the results are shown for the kinematic range 1 (GeV/c)(2) < Q(2) < 100 (GeV/c)(2) in photon virtuality, 0.004 < x < 0.7 in the Bjorken scaling variable and W > 4GeV/c(2) in the mass of the hadronic final state. The deuteron double-spin asymmetry A(1)(d) and the deuteron longitudinal-spin structure function g(1)(d) are presented in bins of x and Q(2). Towards lowest accessible values of x, g(1)(d) decreases and becomes consistent with zero within uncertainties. The presented final g(1)(p) values together with the recently published final g(1)(p) values of COMPASS are used to again evaluate the Bjorken sum rule and perform the QCD fit to the g(1) world data at next-to-leading order of the strong coupling constant. In both cases, changes in central values of the resulting numbers are well within statistical uncertainties. The flavour singlet axial charge a(0), which is identified in the MS renormalisation scheme with the total contribution of quark helicities to the nucleon spin, is extracted at next-to-leading order accuracy from only the COMPASS deuteron data: a(0)(Q(2) = 3 (GeV/c)(2)) = 0.32 +/- 0.02(stat) +/- 0.04(syst) +/- 0.05(evol). Together with the recent results on the proton spin structure function g(1)(p), the results on g(1)(d) constitute the COMPASS legacy on the measurements of g(1) through inclusive spin-dependent deep inelastic scattering.

    The Flipped Classroom and Student Learning at Compulsory School in Sweden: A Longitudinal, Qualitative Study2017In: Journal of Education and Practice, ISSN 2222-1735, E-ISSN 2222-288X, Vol. 8, no 18, 77-86 p.Article in journal (Refereed)
    Abstract [en]

    This article presents the results of a longitudinal study at an elementary school where teachers and students used the Flipped Classroom teaching methodology. Longitudinal studies of how the Flipped Classroom can support student learning are of importance because this methodology has become quite popular of late. Notwithstanding this, there is currently lack of broad and deep knowledge of its effects at the elementary school level. The research object is therefore important to study and longitudinal studies can provide us with important results, which can be used in teaching practices. Data was continually collected via observations and interviews with teachers and students over a period of three terms. The theoretical framework used in the study is ‘life-world phenomenology’, which entails that the point of departure for the study is the students and teachers’ living experiences of how the Flipped Classroom shows itself in the context of their school-life. A central issue with respect to the data collection was that the researchers were as unobtrusive as possible during their observations, so as to not affect normal school activities. This was done so as to understand the abilities that the students developed and how their way of working at school changed. The results show that the Flipped Classroom had a positive influence on the majority of students since they developed a sense of agency in their learning which was demonstrated by their taking the initiative as they progressed with their learning. Furthermore, they developed problem-solving skills and came to believe in their own potential for success. However, this teaching methodology did not suit every student, because it entailed change that was difficult for some of them to deal with. This was the case with students who needed a traditional structure to their teaching and who were more comfortable when the teacher was the central figure in the teaching process.

    Bunge vs. Bhaskar. Some critical reflections of the originality in new theories

    This article takes its point of departure in the issue of the originality in new theories. By a comparative analysis of the thesis in Mario Bunge’s ”Causality” and Roy Bhaskar’s ”A Realist Theory of Science”, it is argued that many of the key concepts in the critical realist philosophy has a history that goes beyond that of Roy Bhaskar’s prominent book. The key-concepts that are compared are ”emergence”, ”the transitive and intransitive dimensions of science”, ”transfactuality” and ”the epistemic fallacy”. The analysis shows that the meaning of the concepts has been used and referred to in texts written earlier than ”A Realist Theory of Science”. The conclusion of the article is that none of the key-concepts discussed has its origin in ”A Realist Theory of Science”, although the arguments for and the presentation of them might be new and somewhat different.

    Abstract [en]

    This paper examines how competition within a movement affects the overall growth of the movement’s membership. Using data on the Swedish temperance movement, I test hypotheses from three different theories; the theory of cross pressure, rational choice theory, and organizational ecology. My main finding is that intra-movement competition tends to be beneficial for the movement as a whole: as the number of competing organizations increases, the total membership increases. This finding conform best with rational choice theory that emphasize that competition invigorates a social movement.

    Abstract [en]

    This study focuses on social relations in school classes and their importance for mental well-being in middle childhood. The aspect of social relations under study is the status relations in the school class and both the individual’s own status position and the status distribution of the school class as a whole was considered. The number of children analysed was 13,932 and the number of school classes 524. The results show a clear association at individual level: the higher the status position the more uncommon is malaise. This is true both when malaise is reported by the teacher and by a parent, for both boys and girls and irrespective of the number of friends. The association was also generally present within school. It exists regardless of grade, type of school and class size. Furthermore, a minority of the classes did not contain any outsiders and here malaise was less common in all status positions. Consequently, that some children are put outside the group indicates problematic conditions for the persons in question but also for the other group members.

    Auschwitz: det moderna projektets kulmen eller kollaps?1999In: Sociologisk forskning, ISSN 0038-0342, Vol. 36, no 2, 5-35 p.Article in journal (Refereed)
    Abstract [en]

    Two opposite parties in the debate about modernity, the postmodernists and the modernists, share a common concern, Holocaust, which in both cases serves as a reference of almost absolute evil in modern history. Its interpretation, however, varies. Postmodern Zygmunt Bauman, focusing tendencies of repression instead of justice or welfare in the process of modernization, explains Holocaust as a product of modernity. After accounting for Bauman’s position, the völkisch and romantic roots of Nazi ideology are reviewed, presenting a different picture. Various interpretations of the relationship of Nazism to modernization are contrasted, ending up in Jeffrey Herf’s concept of ”reactionary modernism”, which underlines the peculiar synthesis of technique-affirmation and romantic anti-modernism in Nazi ideology. A critique of Bauman’s postmodernistic position concludes, infering that the German disaster was due to ”too little” institutionalized Enlightenment. Modernization meant the loss of a unified worldview and of traditional authority. God was overthrown. To affirm modernity hence means to accept these losses, implicating that society has to find its normativity through processes of free political will-formation. This did not happen in Nazi Germany, where normativity was placed in an ideological sphere characterized by sacredness. Holocaust resulted from the collaps of the project of modernity.

    Abstract [sv]

    Byggandet av Nya Karolinska Solna (NKS) är förknippat med en dröm från slutet av 1990-talet om ett sjukhus som ett nav i ett internationellt konkurrenskraftigt universitetssjukvårdssystem. Det skulle vara ett specialsjukhus för regionen och inta en central roll för utvecklingen av Stockholmsregionen till ett biomedicinskt kraftcentrum. 2008 fattades beslutet om att bygga det nya sjukhuset och fylla det med ett nytt verksamhetsinnehåll. Beslutsprocessen rörande verksamhetsinnehållet vid NKS har präglats av interimistiska beslut och utvecklats till en process som förändrat villkoren för andra beslutsprocesser med stora ekonomiska och praktiska återverkningar för hälso- och sjukvården i Stockholmsregionen.

    Här redovisas hur det gick till när besluten om vård, forskning och utbildning vid NKS fattades. Och framför allt diskuteras NKS-projektets otillräckliga beslutsunderlag och de utdragna beslutsprocessernas konsekvenser för det regionala vårdsystemet.

    Design Optimization and Realization of 4H-SiC Bipolar Junction Transistors2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    4H-SiC-based bipolar junction transistors (BJTs) are attractive devices for high-voltage and high-temperature operations due to their high current capability, low specific on-resistance, and process simplicity. To extend the potential of SiC BJTs to power electronic industrial applications, it is essential to realize high-efficient devices with high-current and low-loss by a reliable and wafer-scale fabrication process. In this thesis, we focus on the improvement of the 4H-SiC BJT performance, including the device optimization and process development.

    To optimize the 4H-SiC BJT design, a comprehensive study in terms of cell geometries, device scaling, and device layout is performed. The hexagon-cell geometry shows 42% higher current density and 21% lower specific on-resistance at a given maximum current gain compared to the interdigitated finger design. Also, a layout design, called intertwined, is used for 100% usage of the conducting area. A higher current is achieved by saving the inactive portion of the conducting area. Different multi-step etched edge termination techniques with an efficiency of >92% are realized.

    Regarding the process development, an improved surface passivation is used to reduce the surface recombination and improve the maximum current gain of 4H-SiC BJTs. Moreover, wafer-scale lift-off-free processes for the n- and p-Ohmic contact technologies to 4H-SiC are successfully developed. Both Ohmic metal technologies are based on a self-aligned Ni-silicide (Ni-SALICIDE) process.

    Regarding the device characterization, a maximum current gain of 40, a specific on-resistance of 20 mΩ·cm2, and a maximum breakdown voltage of 5.85 kV for the 4H-SiC BJTs are measured. By employing the enhanced surface passivation, a maximum current gain of 139 and a specific on-resistance of 579 mΩ·cm2 at the current density of 89 A/cm2 for the 15-kV class BJTs are obtained. Moreover, low-voltage 4H-SiC lateral BJTs and Darlington pair with output current of 1−15 A for high-temperature operations up to 500 °C were fabricated.

    This thesis focuses on the improvement of the 4H-SiC BJT performance in terms of the device optimization and process development for high-voltage and high-temperature applications. The epilayer design and the device structure and topology are optimized to realize high-efficient BJTs. Also, wafer-scale fabrication process steps are developed to enable realization of high-current devices for the real applications.

    An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. It is difficult or impossible to avoid non-metallic inclusions in the liquid steel, but by a selection of a good RBM in the SEN clogging can be reduced.

     

    Different process steps were evaluated during the casting process in order to reduce the clogging tendency. First, the preheating of the SEN was studied. The results showed that the SEN can be decarburized during the preheating process. In addition, decarburization of SEN causes a larger risk for clogging. Two types of plasma coatings were implemented to protect the RBM, to prevent reactions with the RBM, and to reduce the clogging tendency. Calcium titanate (CaTiO3) mixed with yttria stabilized zirconia (YSZ) plasma coatings were tested in laboratory and pilot plant trials, for casting of aluminium-killed low-carbon steels. For casting of cerium alloyed stainless steels, YSZ plasma coatings were tested in laboratory, pilot plant and industrial trials. The results showed that the clogging tendency was reduced when implementing both coating materials.

     

    It is also of importance to produce clean steel in order to reduce clogging. Therefore, the steel cleanliness in the tundish was studied experimentally. The result showed that inclusions originated from the slag, deoxidation products and tundish refractory and that they were present in the tundish as well as in the final steel product.

    Jordpackning och packningskontroll vid vägbyggnad1971Report (Other academic)
    Abstract [sv]

    Den mycket starka utveckling som vägtrafiken genomgått efter andra världskriget har bl.a. inneburit en markant ökning av trafikens intensitet, hastighet och tyngd (axel- och boggitryck). Härav har följt såväl växande fordringar på vägarnas bärighet och jämnhet som på deras kapacitet och trafiksäkerhet. Då alla prognoser för trafikutvecklingen inom landet pekar mot en fortsatt stark ökning i vägtrafiken och mot en fortsatt övergång till allt tyngre lastbilar, måste antagandet, att trafikantens krav på vägarna kommer att tilltaga i samma eller sannolikt snabbare takt, anses vara välgrundat.

    På senare tid har från olika håll framförts den åsikten, att de svenska vägarnas jämnhet icke är tillfredsställande samt att orsaken härtill är, att vägkroppens olika lager icke packats tillräckligt. Det har därför ansetts, att de nu gällande föreskrifterna för jordpackning vid vägbyggnad måste skärpas. Med anledning härav har Statens vägverk uppdragit åt Statens väginstitut, att verkställa en översyn av de normer och rekommendationer för jordpackning, som ingår i Väg- och vattenbyggnadsstyrelsens byggnadstekniska anvisningar (BYA) av år 1963. Översynen har även omfattat studium av dels olika länders krav på jordpackning, dels olika laboratorie- och fältmetoders användbarhet för bestämning av jord- och vägbyggnadsmaterials packningsegenskaper och packningstillstånd. Med hänsyn till att statens väginstitut icke sedan 1954, då institutets meddelande nr 87 "Om komprimering av jord" (Bruzelius) utgavs, publicerat någon mer omfattande sammanställning över till jordpackningskomplexet hörande frågor, har Väginstitutet ansett det vara motiverat, att redovisa denna översyn i en rapport mer omfattande än en promemoria.

    Energy Efficient Renovation Strategies for Swedish and Other European Residential and Office Buildings2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The high energy use in the European building stock is attributable to the large share of old buildings with poor energy performance. Energy renovation of buildings is therefore vital in the work towards energy efficiency and reduced environmental impact in the EU. Yet, the strategies and energy system implications of this work have not been made clear, and the rate of building renovation is currently very low.

    The aim of this thesis is to investigate the economic and environmental aspects of energy renovation strategies, with two main objectives:

    • Renovation of Swedish district heated multi-family houses, including life-cycle cost and environmental analysis and impact on the local energy system;

    • Renovation of European residential and office buildings, including life-cycle cost and environmental analysis and influence of climatic conditions.

    Buildings typical for the respective regions and the period of construction 1945-1970 were simulated, in order to determine the feasibility and energy saving potential of energy renovation measures in European climates. A variety of systems for heating, cooling and ventilation were studied, as well as solar energy systems, with focus on heat pumps, district heating, low-temperature heating systems and air heat recovery.

    Compared to normal building renovation, energy renovation can often reduce the life-cycle costs and environmental impact. In renovation of typical European office buildings, as well as Southern European multi-family houses, more ambitious renovation levels can also be more profitable.

    Exhaust air heat pumps can be cost-effective complements in district heated multi-family houses, while ventilation with heat recovery is more expensive but also more likely to reduce the primary energy use. From a system perspective, simple exhaust ventilation can reduce the primary energy use in the district-heating plant as much as an exhaust air heat pump, due to the lower electricity use.

    Vägar byggda med bark1970Report (Refereed)
    Abstract [sv]

    Bark har under senare år fått användning vid vissa vägar i de norrländska länen samt i Kopparbergs och Värmlands län. Vid de flesta av dessa vägar har barken tjänstgjort som tjälisolerande medel och sålunda utövat ett skydd mot tjälskador och då främst tjällyftningsskador, bl.a. längsgående tjälsprickor. Barklagret har därvid givits en triangulär tvärsnittsform (= mittkil enligt Väg- och vattenbyggnadsstyrelsens anvisningar). Bark har använts i mycket tjälfarliga terränglägen dvs huvudsakligen i skärningar och där undergrunden uppbygges av mycket tjälfarliga sediment (finmo, mjäla, lättlera) och där grundvattenståndet är högt. Barkens tjälskyddande effekt härrör sig från dess stora frysmotstånd. I vissa fall har man utnyttjat dess låga volymvikt genom att använda den i lättbankar. Bark kan också ha använts enbart som fyllnadsmaterial.

    Tjälskyddsåtgärder vid Långsele-Sollefteå, väg 87, Västernorrlands län1970Report (Other academic)
    Abstract [sv]

    På grund av tjällyftning uppkommande Vägskador kan motverkas eller helt elimineras genom speciella åtgärder antingen vid vägens byggande eller senare, då den kommit i bruk, dvs genom reparationer vid lokala skadesträckor.

    Vare sig målet är att få en helt tjälskadefri väg eller enbart en till viss grad tjälsäker väg, måste man kunna bedöma var i terrängen betingelser finns för tjälskjutning av sådan art att den kan åstadkomma skador hos den färdigbyggda vägen. Vid vägföretaget Långsele - Sollefteå är markförhållandena komplexa och på längre sträckor ej möjliga att utreda med normal arbetsinsats. De utförda markundersökningarna har också visat sig icke vara nog detaljerade för att alla för skadande tjällyftning betydelsefulla inhomogeniteter i marken skulle kunna uppspåras.

    Som brukligt är utgick man vid bedömning av tjälskyddsåtgärder från ett tjälskyddskrav, som innebar ett delvis tjälskydd. Tjällyftningsskador var alltså förväntade, men blev första vintern (1968 - 69) så svåra, att rätt omfattande reparationer måste utföras.

    Påföljande vinter hade skadegraden hos vägen väsentligt gått ned, men på många sträckor kunde fortfarande skador men av moderatare typ noteras, förutom att vägbanan inom vissa avsnitt var "orolig".

    Contributions to the development of a framework for modifying the Swedish flexible pavement design model1970Report (Other academic)
    Abstract [en]

    Design procedures serve as guides to the orderly consideration of all relevant aspects of a design problem. Sound procedures can promote uniformly good performance of structures, in both a technical and economic sense. Incomplete or erroneous procedures can obviously promote faulty performance. It is worth noting, however, that either good or bad design guides, tables and so forth may stifle creativity if viewed and used in a dogmatic, rigid fashion.

    Though many relatively unsophisticated design procedures have been used in the past to select dimensions for the road pavement structure, it is now obvious that for developed countries the rate of expenditure for new roads and major improvements, the rate of traffic growth and the availability of new materials all suggest a very high order of efficiency in this design process as being required for the future. Unfortunately such efficiency has been elusive, in part for the reason that roadbuilding has been, and continues to be, very much an "art", but also because research and development efforts have not followed a consistent, systematic plan of attack. The problems have been too numerous, too urgent and too multidisciplinary in nature while the research and deveIopment efforts have been too fragmented to permit such an approach. It would seem that improved pavement design methods can be developed only within a carefully structured framework. This framework must reflect an awareness of the very rich resources of past road research, treat the unique conditions of actual roadbuilding practice, and have a breadth and flexibility that modern systems engineering makes possible.

    The purpose of this paper is to make contributions to the deveIopment of a framework such as that noted above for Sweden. It contains a selective review of recent USA (and some other) literature treating principal elements of the pavement design process, some examples of the systems approach to pavement design, and examples of current pavement design procedures. It was felt that in these areas a person with no experience in Sweden might nevertheless offer something of value to the total effort.

    Traffic as factor in pavement design1970Report (Other academic)
    Abstract [en]

    The question of whether or not traffic load repetitions should be considered in pavement design, and if so by what relationship, is considered. From reports covering widely different experiences it is concluded that a continuum of pavement response to traffic has been described. Local design practice together with traffic and environmental factors determine the sensitivity for any particular case. Comparisons between dimensions for roads of similar specification in Sweden, the UK and several states of the USA suggest that Swedish pavements might be rather insensitive to traffic loads.

    A method for treating mixed traffic is required for the development of a pavement design traffic index. The equivalent wheel load concept, with equivalency based on equal decrements of serviceability, has been widely used for this purpose in the USA. This approach is justified through mathematical models relating pavement thickness to load applications. Such models reflect specific conditions and pavement design methods and so must be validated before any general adoption of load equivalency factors developed elsewhere can be considered. A method for such validation based on experience in Minnesota is described.

    Disciplinary discernment from Hertzsprung-Russell-diagrams2017Conference paper (Other academic)
    Abstract [en]

    This paper aim at investigating what astronomy students and experts discern from the multitude of different disciplinary affordances available in Hertzsprung-Russell (HR) diagrams. HR-diagrams are central to all of astronomy and astrophysics and used extensively in teaching. However, knowledge about what students and experts discern from these disciplinary representations are not well known at present. HR-diagrams include many disciplinary affordances that may be hidden to the novice student, hence we aim at investigating and describing what astronomy students at different university levels (introductory, undergraduate, graduate), and astronomy educators/professors, discern from such representation – referred to as disciplinary discernment (Eriksson, Linder, Airey, & Redfors, 2014). Data from a web based questionnaire were analysed using the Anatomy of Disciplinary Discernment (ADD) framework by Eriksson et al. (2014). Preliminary results show (1) the developmental nature of disciplinary discernment from the HR-diagram by the participants and (2) the large discrepancy between disciplinary discernment by the astronomy educators and their students. We describe and discuss the qualitative nature of these differences and how this can have implications for teaching and learning astronomy.

    Doing science by waving hands: Talk, symbiotic gesture, and interaction with digital content as resources in student inquiry2017In: Physical Review Special Topics : Physics Education Research, ISSN 1554-9178, E-ISSN 1554-9178, Vol. 13, no 2, 020104Article in journal (Refereed)
    Abstract [en]

    In this paper, we investigate some of the ways in which students, when given the opportunity and an appropriate learning environment, spontaneously engage in collaborative inquiry. We studied small groups of high school students interacting around and with an interactive whiteboard equipped with Algodoo software, as they investigated orbital motion. Using multimodal discourse analysis, we found that in their discussions the students relied heavily on nonverbal meaning-making resources, most notably hand gestures and resources in the surrounding environment (items displayed on the interactive whiteboard). They juxtaposed talk with gestures and resources in the environment to communicate ideas that they initially were not able to express using words alone. By spontaneously recruiting and combining a diverse set of meaning- making resources, the students were able to express relatively fluently complex ideas on a novel physics topic, and to engage in practices that resemble a scientific approach to exploration of new phenomena.

    Metastatic spinal cord compression as the first sign of malignancy: Outcome after surgery in 69 patients2017In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 88, no 4, 457-462 p.Article in journal (Refereed)
    Abstract [en]

    Background and purpose - Metastatic spinal cord compression (MSCC) as the initial manifestation of malignancy (IMM) limits the time for diagnostic workup; most often, treatment is required before the final primary tumor diagnosis. We evaluated neurological outcome, complications, survival, and the manner of diagnosing the primary tumor in patients who were operated for MSCC as the IMM.

    Patients and methods - Records of 69 consecutive patients (51 men) who underwent surgery for MSCC as the IMM were reviewed. The patients had no history of cancer when they presented with pain (n = 2) and/or neurological symptoms (n = 67).

    Results - The primary tumor was identified in 59 patients. In 10 patients, no specific diagnosis could be established, and they were therefore defined as having cancer of unknown primary tumor (CUP). At the end of the study, 16 patients were still alive (median follow-up 2.5 years). The overall survival time was 20 months. Patients with CUP had the shortest survival (3.5 months) whereas patients with prostate cancer (6 years) and myeloma (5 years) had the longest survival. 20 of the 39 patients who were non-ambulatory preoperatively regained walking ability, and 29 of the 30 ambulatory patients preoperatively retained their walking ability 1 month postoperatively. 15 of the 69 patients suffered from a total of 20 complications within 1 month postoperatively.

    Interpretation - Postoperative survival with MSCC as the IMM depends on the type of primary tumor. Surgery in these patients maintains and improves ambulatory function.

    Model for calculating the effect of longitudinal profiles on the speed of heavy vehicles1970Report (Other academic)
    Abstract [en]

    The knowledge of the effects which the vertical alignment of a road produces on traffic is necessary for preparation of appropriate standards and recommendations relating to gradients and to vehicle-climbing lanes. Furthermore this knowledge constitutes an indispensable element of the information which is required for economic calculations in traffic engineering. In fact, very extensive information is needed in order that the abovementioned effects may be determined in a satisfactory manner. Among other things, it is necessary to know the geometric road design features, the traffic volume, and the classification of traffic according to type of vehicle. Moreover, it is required to know the effects of the vertical alignment on free-moving vehicles of various types, and the influence of sight conditions and opposite-direction traffic on the frequency of overtaking and passing. A complete treatment of this problem will be carried out with the help of simulation by means of automatic data processing equipment. A model for simulation of traffic on two-lane roads is at present in preparation at the National Swedish Road Research Institute.

    As has been pointed out in the above, the necessary basis for the simulation comprises, among other things, the knowledge of the effects produced on free-moving vehicles by the vertical alignment of the road. Studies of the variations in the speeds of free-moving vehicles with the distance on upgrades have therefore been made for this purpose and the results are presented in this report.

    Treatment of premenstrual dysphoric disorder with the GABA(A) receptor modulating steroid antagonist Sepranolone (UC1010)-A randomized controlled trial2017In: Psychoneuroendocrinology, ISSN 0306-4530, E-ISSN 1873-3360, Vol. 80, 46-55 p.Article in journal (Refereed)
    Abstract [en]

    Context: Allopregnanolone is a metabolite from progesterone and a positive modulator of the GABA(A) receptor. This endogenous steroid may induce negative mood in sensitive women when present in serum levels comparable to the premenstrual phase. Its endogenous isomer, isoallopregnanolone, has been shown to antagonize allopregnanolone effects in experimental animal and human models.

    Objective: The objective was to test whether inhibition of allopregnanolone by treatment with the GABA(A) modulating steroid antagonist (GAMSA) Sepranolone (UC1010) during the premenstrual phase could reduce symptoms of the premenstrual dysphoric disorder (PMDD). The pharmacokinetic parameters of UC1010 when given as a subcutaneous injection were measured in healthy women prior to the study in women with PMDD.

    Design: This was an explorative randomized, double-blind, placebo-controlled study.

    Setting: Swedish multicentre study with 10 centers.

    Participants: Participants were 26 healthy women in a pharmacokinetic phase I study part, and 126 women with PMDD in a phase II study part. Diagnosis followed the criteria for PMDD in DSM-5 using Daily Record of Severity of Problems (DRSP) and Endicott's algorithm.

    Intervention: Subjects were randomized to treatment with UC1010 (10 or 16 mg) subcutaneously every second day during the luteal phase or placebo during one menstrual cycle.

    Outcome measures: The primary outcome measure was the sum of all 21 items in DRSP (Total DRSP score). Secondary outcomes were Negative mood score i.e. the ratings of the 4 key symptoms in PMDD (anger/irritability, depression, anxiety and lability) and impairment (impact on daily life).

    Results: 26 healthy women completed the pharmacokinetic phase I study and the dosing in the following trial was adjusted according to the results. 106 of the 126 women completed the phase II study. Within this group, a significant treatment effect with UC1010 compared to placebo was obtained for the Total DRSP score (p = 0.041) and borderline significance (p = 0.051) for the sum of Negative mood score. Nineteen participants however showed symptoms during the follicular phase that might be signs of an underlying other conditions, and 27 participants had not received the medication as intended during the symptomatic phase. Hence, to secure that the significant result described above was not due to chance, a post hoc sub-group analysis was performed, including only women with pure PMDD who completed the trial as intended (n =60). In this group UC1010 reduced Total DRSP scores by 75% compared with 47% following placebo; the effect size 0.7 (p = 0.006), and for sum of Negative mood score (p=0.003) and impairment (p =0.010) with the effect size 0.6. No severe adverse events were reported during the treatment and safety parameters (vital signs and blood chemistry) remained normal during the study.

    Conclusions: This explorative study indicates promising results for UC1010 as a potential treatment for PMDD. The effect size was comparable to that of SSRIs and drospirenone containing oral contraceptives. UC1010 was well tolerated and deemed safe.

    Changes in speeds of vehicles on horizontal curves1970Report (Other academic)
    Abstract [en]

    An essential part of the model for traffic simulation which is in preparation at the National Swedish Road Research Institute is a description of the variations in the speeds of road vehicles during their passage through horizontal curves.

    Studies of the speed adaptation on horizontal curves have been made at the Road Research Institute on several occasions in the course of the period from 1965 to 1967. A common feature of these studies is that they have been carried out under left-hand traffic conditions. It was therefore desirable to examine, among other things, the effect produced by righthand traffic on the speeds of vehicles on curves. It was to be expected that the sight from the inner lanes of the curves would be improved for vehicles equipped with steering wheels on the left-hand side, which are completely predominant in Sweden. In order to study the above-mentioned effect, investigations have been made in 1969 at some places where similar measurements had been performed in left-hand traffic, so that reference data were available for these places.

    In the first investigations, a study was made of free-moving vehicles. They were defined as vehicles separated by a time gap of at least 6 seconds from the vehicle ahead. The results of these investigations proved to be in close agreement with those of Taragin's tests carried out in 1954. It was found, among other things, that the speed adaptation took place in most cases before the curve, and was then maintained constant throughout the curve. Furthermore, the difference in speed between the vehicles moving in the inner and outer traffic lanes was very slight.

    In another investigation, the variation in the Speed of each vehicle with the distance was determined by measuring the travel time over 8 consecutive road sections. This investigation was carried out on free-moving vehicles at 25 places in Central Sweden, and covered 1 200 vehicles in all.

    Hastighetsförlopp i lutningar1970Report (Other academic)
    Abstract [sv]

    Kunskap om hur en vägs vertikala linjeföring påverkar trafiken är nödvändig för utarbetande av lämpliga normer och anvisningar avseende lutningar och stigningsfält. Denna kunskap utgår även en nödvändig del av den information som erfordras för trafikekonomiska beräkningar. För att kunna ge ett tillfredsställande svar på frågan hur den vertikala linjeföringen påverkar trafiken erfordras en mängd information. Man måste bl.a. känna väggeometrin, trafikens storlek och dess sammansättning. Vidare måste man veta hur fria fordon av olika typer påverkas av den vertikala linjeföringen samt hur omkörningsfrekvensen påverkas av siktförhållanden och mötande trafik. En fullständig behandling av problemet är avsedd att ske med hjälp av simulering i dator. En simuleringsmodell för trafik på tvåfältiga vägar utarbetas f.n. vid institutet. Ett nödvändigt underlag för denna simulering är således bl.a. kunskap om hur fria fordon påverkas av vägens vertikala linjeföring. Studier av fria fordons hastighetsförlopp i lutningar har därför utförts. Resultatet från dessa redovisas i denna rapport.

    För att beskriva hastighetsförloppet i en uppförslutning ansattes en fysikalisk modell. De krav som ställdes på modellen var att den skulle vara enkel att använda, samt att den skulle avbilda varje enskilt fordons hastighetsförlopp väl. Det vill säga hela fordonspopulationen skulle kunna beskrivas och ej endast ett typfordon vilket varit vanligt vid tidigare studier av detta problem.

    A group-based traffic signal control with adaptive learning ability2017In: Engineering applications of artificial intelligence, ISSN 0952-1976, E-ISSN 1873-6769Article in journal (Refereed)
    Abstract [en]

    Group-based control is an advanced traffic signal strategy capable of dynamically generating phase sequences at intersection. Combined with the phasing scheme, vehicle actuated timing is often adopted to respond to the detected traffic. However, the parameters of a signal controller are often predetermined in practice, and the control performance may suffer from deterioration when dealing with highly fluctuating traffic demand. This study proposes a group-based signal control approach capable of making decisions based on its understanding of traffic conditions at the intersection level. In particular, the control problem is formulated using a framework of stochastic optimal control for multi-agent system in which each signal group is modeled as an intelligent agent. The agents learn how to react to traffic environment and make optimal timing decisions according to the perceived system states. Reinforcement learning, enhanced by multiple-step backups, is applied as the kernel of the intelligent control algorithm, where each agent updates its knowledge on-line based on a sequence of states during the process. In addition, the proposed system is designated to be compatible with the prevailing signal system. A case study was carried out in a simulation environment to compare the proposed control approach with a benchmark controller used in practice, group-based vehicle actuated (GBVA) controller, whose parameters were off-line optimized using a genetic algorithm. Simulation results show that the proposed adaptive group-based control system outperforms the optimized GBVA control system mainly because of its real-time adaptive learning capacity in response to the changes of traffic demand.

    Joint Pilot Sequence Design and Power Control for Max-Min Fairness in Uplink Massive MIMO2017In: IEEE International Conference on Communications (ICC), 2017, Institute of Electrical and Electronics Engineers (IEEE), 2017Conference paper (Refereed)
    Abstract [en]

    This paper optimizes the pilot assignment and pilottransmit powers to mitigate pilot contamination in MassiveMIMO (multiple-input multiple-output) systems. While priorworks have treated pilot assignment as a combinatorial problem,we achieve a more tractable problem formulation by directlyoptimizing the pilot sequences. To this end, we compute alower bound on the uplink (UL) spectral efficiency (SE), forRayleigh fading channels with maximum ratio (MR) detectionand arbitrary pilot sequences. We optimize the max-min SEwith respect to the pilot sequences and pilot powers, under powerbudget constraints. This becomes an NP-hard signomial problem,but we propose an efficient algorithm to obtain a local optimumwith polynomial complexity. Numerical results manifest the nearoptimality of the proposed algorithm and show significant gainsover existing suboptimal algorithms.

    Investing in Lean to Improve Basic Capabilities: A strategy for System Supply?2017In: Journal of Industrial Engineering and Management, ISSN 2013-8423, E-ISSN 2013-0953, Vol. 10, no 1Article in journal (Refereed)
    Abstract [en]

    Purpose: This paper describes the perceived effects of implementing lean production in aSwedish SME contract manufacturer. Especially focused are the effects on, and possible tradeoffsbetween, cost-efficiency and flexibility.Design/methodology/approach: SME suppliers need basic capabilities of qualitativeproduction performance as stepping-stones to develop more system supplier capabilities foradded customer value. Development of stable production processes is seen as a way to reachstable basic performance, efficient and with higher resource utilization. Quality is a precursor todelivery performance as well as to cost reduction and flexibility. This is a longitudinal single casestudy of a SME supplier striving to become a system supplier. Two main sources of datacollection are used: interviews and the main author’s presence as employee and businessdeveloper, participating in and following up the ongoing change process.Findings: Analyzing the development over time illustrated the importance of context andcontent for the change process. Two specific findings appeared: (1) An initial effect was animportant “eye-opener” for the balance between cost efficiency and flexibility in the organization.(2) Process orientation, as the basis of both lean and agile approaches, allows many improvementswithout any conflicts or trade-offs between these two goals. Stability in the production leads to increased controllability, initially resulting in both higher cost-efficiency and higher flexibility. Asthe organization develops however, strategic considerations relating to the chosen market strategymight occur: cost leadership or differentiation.Research limitations/implications: These results reflect the experiences of one SME supplierand further studies are needed for generalizability.Originality/value: The study increases the understanding of how a SME may develop stableprocesses in its different supplier-customer contexts. The study points at some necessary basiccomponents of this process approach as a first step for the transition to system supplier.

    Abstract [en]

    One way for a small subcontractor to meet increasing global competitionis to develop a system supplying ability, which implies more focus onlogistical issues and a larger overall responsibility in the supply chain.Certain logistics capabilities have been identified as important to a smallormedium-sized subcontractor in order to cope with the systemsupplying role. Interviews have been carried out in a multiple case studywith the purpose of identifying important resources for a smaller supplierwith the ambition of forming logistics capabilities to support systemsupply. Resources within three different areas have been identified:organizational, competence base, and tools. Conclusions from acomparison among three companies, with different degrees of systemsupplying services, point out the importance of an organization with clearand distinct responsibilities and authorities. Competencies in logistics andenhanced understanding and use of IT support and communicationsystems are identified as areas to improve for the smaller companies.

    The growth of virtual reality and the decline of intellectual dialog in the community of social scientists

    For about two decades now, leading Swedish economists have been arguing that the expansion of Sweden's welfare state since 1970 has caused its economic growth to lag behind that of other comparable countries. As main evidence for this causal interpretation, they have pointed to the fact that since the early 1970s Sweden's percentage growth of GDP per capita has been below the OECD-average. In these terms, however, Sweden's growth lagged behind the OECD-average by the same amount already in the 1950s and 60s, the effect thus preceding its assumed cause by two decades. Furthermore, also other relatively rich countries such as Switzerland and the United States, have had percentage growth rates below the OECD-average. This reflects the so called catch-up effect, which tends to give the originally less rich countries a higher percentage growth rates than the originally rich countries, among them Sweden, Switzerland and the United States. A causal interpretation of this percentage difference to the OECD-average in terms of a ”Swedish” welfare state is thus not possible. Henrekson is however a true believer in the irrelevance of the catch-up effect, something which makes him shut his eyes.

    The economic growth of Sweden and the objectivity of social scientists

    In an article in Sociologisk Forskning (2/98) Walter Korpi maintains that the claim by Swedish academic economists that Sweden’s economic growth has been slow compared to other rich countries is at odds with the empirical facts. Consequently, unless Sweden has grown slowly, an often cited basis for questioning the Swedish model is invalidated. Korpi also asserts that the discussion reveals a severe objectivity problem among Swedish academic economists. In this article Magnus Henrekson rebuts Korpi's allegations. The available facts show that Sweden was lagging behind relative to a broad aggregate ofother industrialized countries up to 1990, and this tendency is further reinforced if the 1990s is included in the comparison. As a corallary, it is an important task for future research to examine the factors that can potentially explain this unfavorable development. One hypothesis worthy of additional exploration is whether the Swedish model with its large public sector and strongly redistributive policies provides part of the explanation. As regards the objectivity problem in social science research in Sweden, Henrekson argues that, if anything, the discussion of Sweden’s growth problem shows that Walter Korpi is the one who has been lacking in scientific objectivity in this particular instance.

    Réalisme magique ou fantastique ?: Stratégies narratives dans la réappropriation des traumatismes historiques2017In: Moderna Språk, ISSN 2000-3560, E-ISSN 2000-3560, Vol. 111, no 1, 59-82 p.Article in journal (Refereed)
    Abstract [en]

    This article starts with a theoretical discussion about the differences and the similitudes between Magical Realism and the Fantastic, especially concerning their relation to the category of the real, and consequently the possibility to apply the two concepts to the writing about the past. These genres, or these modes, which I argue is a more useful way to see them, might seem incompatible with the goal of writing about real events having occurred in the past. A realistic style, in which reality is considered according to the principles of rationality and logic, is traditionally preferred in such endeavors. Fiction in general can be seen as inappropriate when dealing with historiography. However, it has been argued that fiction, even of the kind that seems antirealist, can be used to write about the real past, especially a past marked by trauma.

    On the basis of this theoretical introduction, I analyze two literary works written by two francophone authors who have won the prestigious Goncourt prize: Biblique des derniers gestes by Patrick Chamoiseau (2002) and Trois femmes puissantes by Marie Ndiaye (2009). The two works appear as original ways of appropriation of a traumatic, deeply hidden past, using a style which can be seen as close to magical realism or to the fantastic.

    Gunnar Myrdals relevance for contemporary sociology: value premises and cumulative causation

    Gunnar Myrdal (1898-1977) is one of Sweden’s internationally most renowned social scientists. He has made important contributions to both the fields of economics and sociology, but even to the philosophy and methodology of the social sciences. M criticizes the social sciences for being value-loaded. The values built into the scientific tradition, political interests, and the personal values of the social scientist, has all a tendency to create biases in the scientific results. The only way to ”solve” this problem is that the social scientist brings the value premises that govern a study into the open. It is then possible for others to judge the conclusions reached. M has an ambition to reduce the gap between economics and sociology. For this purpose he has developed a model based on the idea of circular and cumulative causation. This model assumes that economic and non-economic factors are equally important in social processes and that the factors reinforce each other in a specific direction. M uses this model for analyzing business fluctuations, discrimination of Afro-Americans and development processes in third-world countries.

    Globalisering och internationalisering inom vetenskapen1999In: Sociologisk forskning, ISSN 0038-0342, Vol. 36, no 3, 22-36 p.Article in journal (Refereed)
    Abstract [sv]

    Globalization or internationalization in the sciences.

    The main question in this study is whether we can find empirical evidence of globalization in science or not. Usually the increasing number of co-authorships in the sciences is seen as an indicator of increasing research collaboration, which in turn is seen as part of the globalization-trend. Here, this chain is questioned and the relation and the difference between globalization and internationalization in science is investigated and discussed. A number of studies have shown how the amount of research collaboration is increasing but it is not clear that this is actually leading to globalization in science rather than internationalization. Through a number of empirical results the structure of international research collaboration is described. It is concluded that there may very well be an ongoing globalization-trend but this is hardly evident in empirical studies of research collaboration. What can be seen though is a strengthened internationalization-trend. Globalization seems to be a phenomenon that ought to be used more carefully and studied through both bibliometric and other methods.

    Arbetslöshetskoncentration: Ett resultat av negativa attityder gentemot arbete?1999In: Sociologisk forskning, ISSN 0038-0342, Vol. 36, no 3, 4-21 p.Article in journal (Refereed)

    Unemployment concentration: Caused by negative attitudes towards paid work?

    This article studies the concentration of unemployment within families and social networks in Sweden. The study, which is based on two random samples, one consisting of approximately 47000 young people and their parents and one consisting of 3500 unemployed persons, raises the question of whether unemployment concentration mainly is caused by negative values towards employment or by structural factors. The results show that it is common for persons who are unemployed and have experienced longer periods of unemployment to have unemployed family members and friends. The causes of the unemployment concentration can be traced to structural factors such as class, ethnicity, age, unemployment rate and population in the district etc., rather than to the attitudes of the members of the unemployed group.
