    Who put the 'Post' in the Post-Arab Spring?: Towards a Fresh Narrative for North Africa2017Rapport (Annet vitenskapelig)
    Abstract [en]

    When will we see a regional UN headquarter for migration in Rabat, or a centre of excellence for ocean studies in Tripoli? In this policy note, NAI researcher Mikael Eriksson recommends outside-the-box thinking, in an effort to gain a fresh perspective on a region that may have lost its spring-time energy, but not the idea itself – or the people behind it.

    Structural studies of HDL and applications of EM on membrane proteins2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    A large number of proteins interact with biological membranes, either integrated in the membrane (PepTSo2), embedded on a membrane surface (5-lipoxygenase) or encircling a cutout of lipid bilayer (apolipoprotein1 (apoA-I). They function as transporters, receptors or biocatalysts in cellular processes like inflammation or cholesterol transport which are touched upon here. Malfunction of specific membrane proteins are the cause for several diseases or disorders.

    Knowledge of protein structure supports understanding of its mechanism of function. Here, transmission electron microscopy (TEM) was used for structure determination. To obtain structure information to high resolution for membrane proteins, normally surrounded by lipids, demands specific methods and materials for stabilization. Stabilized in detergent the structure of the bacterial transporter PepTSo2 was shown to form a tetramer even bound to substrate. However, with a protein based stabilizer, Salipro, the structure of PepTSo2 could be determined to high resolution.

    High density lipoprotein (HDL) in blood plasma, involved in the removal of cholesterol from peripheral tissues, have a central role in cardiovascular function, metabolic syndrome and diabetes.

    The HDL-particle is composed of two copies of ApoA1 and around hundred lipid molecules. From TEM data, for the first time the clearly discoidal shape could be shown by 3-dimendional reconstructions. These were used for modelling the ApoA1 protein dimer by a "biased fitting" procedure. The results indicate how ApoA1 folds around a lipid bilayer in a disc-shaped structure.

    Modified HDL called nanodiscs were here used to show the Ca2+ dependent binding of 5-lipoxygenase on the nanodisc bilayer and thereby increased production of the inflammatory mediator leukotrieneA4. Dimerization of 5-lipoxygenase inactivates these functions.

    ARSENIC REMOVAL BY PHYTOFILTRATIONAND SILICON TREATMENT: A POTENTIAL SOLUTION FOR LOWERING ARSENIC CONCENTRATIONS IN FOOD CROPS2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Use of arsenic-rich groundwater for crop irrigation can increase the arsenic (As) content in food crops and act as a carcinogen, compromising human health. Using aquatic plant based phytofiltration is a potential eco-technique for removing arsenic from water. The aquatic moss species Warnstorfia fluitans grows naturally in mining areas in northern Sweden, where high concentrations of arsenic occur in lakes and rivers. This species was selected as a model for field, climate chamber and greenhouse studies on factors governing arsenic removal and arsenic phytofiltration of irrigation water. The arsenic and silicon (Si) concentrations in soil, water and plant samples were measured by AAS (atomic absorption spectrophotometry), while arsenite and arsenate species were determined using AAS combined with high pressure liquid chromatography (HPLC) with an anion exchange column. The arsenic content in grains of hybrid and local aromatic rice (Oryza sativa) cultivars with differing arsenic accumulation factor (AF) values was investigated in an arsenic hotspot in Bangladesh. The results showed that arsenic AF was important in identifying arsenic-safer rice cultivars for growing in an arsenic hotspot. The study based on silicon effect on arsenic uptake in lettuce showed that arsenic accumulation in lettuce (Lactuca sativa) could be reduced by silicon addition. The aquatic moss had good phytofiltration capacity, with fast arsenic removal of up to 82% from a medium with low arsenic concentration (1 µM). Extraction analysis showed that inorganic arsenic species were firmly bound inside moss tissue. Absorption of arsenic was relatively higher than adsorption in the moss. Regarding effects of different abiotic factors, plants were stressed at low pH (pH 2.5) and arsenic removal rate was lower from the medium, while arsenic efflux occurred in arsenate-treated medium at low (12°C) and high (30°C) temperature regimes. Besides these factors, low oxygenation increased the efficiency of arsenic removal from the medium. Finally, combining W. fluitans as a phytofilter with a lettuce crop on a constructed wetland significantly reduced the arsenic content in edible parts (leaves) of lettuce. Thus W. fluitans has great potential for use as an arsenic phytofilter in temperate regions.

    En fungerande måltid – innovation mot undernäring Slutrapport - Utmaningsdriven Innovation steg 1 Initiering, hösten 20162016Rapport (Annet vitenskapelig)
    Abstract [sv]

    Det övergripande syftet med projektet "En fungerande måltid - innovation mot undernäring" är att förebygga undernäring bland äldre genom ett holistiskt grepp av måltidssituationen. Fokus är att utveckla en mätmetod för att identifiera risker för fel- och undernäring på verksamhets- samt individnivå, samt att rekommendera åtgärder som minimerar riskerna. Visionen är ett samhälle där måltidssituationens alla beståndsdelar är så välfungerande att undernäring inte längre är ett problem inom omsorg och sjukvård. Runt detta har byggts tjänster och produkter som skapat tillväxt i Sverige. Det finns en stor potential för detta.

    I initieringsprojektet har fokus legat på måltidssituationen på äldreboenden (särskilt boende). Projektet har arbetat tillsammans med två demensboenden samt genomfört två tvärfunktionella workshops, för att skapa förståelse för måltidssituationen, vilka problem som finns, hur de skulle kunna mätas och åtgärdas samt vilka aktiviteter som sker på boendet i relation till måltidssituationen.

    Risken för undernäring är allra högst bland äldre som bor i ordinärt boende, dvs hemma i sin egen bostad med eller utan hemtjänst. Därmed ämnar projektet i steg 2 inkludera denna boendeform parallellt med särskilt boende och utveckla stöd både för den äldre själv, hens anhöriga samt hemtjänstpersonal och omsorgspersonal på boendet. Den rekommenderade lösningen är ett digitalt verktyg för äldre, anhöriga och personal att logga och följa verksamhetens kvalitet i måltidssituation samt individens näringsstatus och som också ger åtgärder för ökad kvalitet och förbättrad näringsstatus.

    Projektet har letts från SP Sveriges Tekniska Forskningsinstitut, enheten Mätteknik, och haft deltagare från Bestic AB, Högskolan Kristianstad, SP Food and BioScience, SP Service Labs samt två stycken boenden i privat drift; Soltorp från Förenade Care och Ribbingsbacke från Temabo. Både Soltorp och Ribbingsbacke har 32 demensplatser. Soltorp har utöver detta en korttidsavdelning med 9 platser och Ribbingsbacke har en somatisk avdelning med 16 platser. För att driva projektet framåt planeras inkludering av hemtjänstverksamhet, kommunal omsorg, tillagningskök samt tillverkare av lösningar för hur måltidssituationen kan förbättras inklusive personalutbildning. Synergieffekter med nätverket Måltid Sverige som verkar för den offentliga måltiden förväntas i att spridas kunskap i samhället om måltidens viktiga roll i relation till vår hälsostatus.

  • Reducing maritime emissions: Policy recommendations for the future of Nordic green marine transport2017Bok (Annet vitenskapelig)
    Abstract [en]

    An overarching conclusion of Nordic Marina’s work in the past three years reveals that the global, and indeed the Nordic shipping and maritime industries, are already boldly moving ahead with regard to emissions reduction, boasting numerous innovative and successful projects contributing toward this goal. In order to take major steps forward, involvement from the government side is needed and currently lacking. There are barriers that industry and government must work on collectively, potentially via joint public-private partnerships. Commitment for the long term is essential, in addition to the demand for strengthening infrastructure and a reliable supply chain to support new fuels. Furthermore, the socio-economic benefits of emissions reduction and the applications of alternative fuels appear to be obscure. The bottom line is this: the time for action is now, for all of us.

    Aktivt åldrande – individuellt anpassade måltidslösningar för hälsa och livskvalitet hos äldre: slutrapport2016Collection/Antologi (Annet vitenskapelig)
    Abstract [en]

    In Sweden, as most parts of the world, the proportion of elderly is increasing. Thenumber of the elderly will shortly exceed the number of younger people. Between2010 and 2030, the number of Europeans aged over 65 will rise by nearly 40%.According to the UN, the increase in life expectancy is mainly due toimprovements in nutrition and hygiene. The growing number of older peopleposes major challenges, but also opportunities for society, business andentrepreneurship.Health issues, primarily food, and quality of life are in focus and strongly relatedto autonomy. It should be possible to live an active and independent life, andpossible to make independent choices, regardless of age, disease and disability.This adds to Quality of Life! To achieve this we created a project in collaborationbetween partners from academia, research institutes, business, industry andsociety. The idea was in a first step to identify target groups along with their needsand desires. Then to design foods and meals adapted to the elderly’s needs andpreferences. Further to develop packaging of the meals that can be used forinformation as well as in the distribution chain. The project invented value chainsfor different types of ordering and distribution of the foods and meals as well as toinclude waste management. The outcome of the project are new knowledge aswell as food products available on the market and other products soon ready to beput on the market.

    Advanced Kalman Filtering Approaches to Bayesian State Estimation2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Bayesian state estimation is a flexible framework to address relevant problems at the heart of existing and upcoming technologies. Application examples are obstacle tracking for driverless cars and indoor navigation using smartphone sensor data. Unfortunately, the mathematical solutions of the underlying theory cannot be translated to computer code in general. Therefore, this thesis discusses algorithms and approximations that are related to the Kalman filter (KF).

    Four scientific articles and an introduction with the relevant background on Bayesian state estimation theory and algorithms are included. Two articles discuss nonlinear Kalman filters, which employ the KF measurement update in nonlinear models. The numerous variants are presented in a common framework and the employed moment approximations are analyzed. Furthermore, their application to target tracking problems is discussed. A third article analyzes the ensemble Kalman filter (EnKF), a Monte Carlo implementation of the KF that has been developed for high-dimensional geoscientific filtering problems. The EnKF is presented in a simple KF framework, including its challenges, important extensions, and relations to other filters. Whereas the aforementioned articles contribute to the understanding of existing algorithms, a fourth article devises novel filters and smoothers to address heavy-tailed noise. The development is based on Student’s t distribution and provides simple recursions in the spirit of the KF. The introduction and articles are accompanied by extensive simulation experiments.

    Flexible Robot to Object Interactions Through Rigid and Deformable Cages2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In this thesis we study the problem of robotic interaction with objects from a flexible perspective that complements the rigid force-closure approach. In a flexible interaction the object is not firmly bound to the robot (immobilized), which leads to many interesting scenarios. We focus on the secure kind of flexible interactions, commonly referred to as caging grasps. In this context, the adjective secure implies that the object is not able to escape arbitrarily far away from the robot which is caging it. A cage is a secure flexible interaction because it does not immobilize the object, but restricts its motion to a finite set of possible configurations. We study cages in two novel scenarios for objects with holes: caging through multi-agent cooperation and through dual-arm knotting with a rope. From these two case studies, we were able to analyze the caging problem in a broader perspective leading to the definition of a hierarchical classification of flexible interactions and cages.

    In parallel to the geometric and physical problem of flexible interactions with objects, we study also the problem of discrete action scheduling through a novel control architecture called Behavior Trees (BTs). In this thesis we propose a formulation that unifies the competing BT philosophies into a single framework. We analyze how the mainstream BT formulations differ from each other, as well as their benefits and limitations. We also compare the plan representation capabilities of BTs with respect to the traditional approach of Controlled Hybrid Dynamical Systems (CHDSs). In this regard, we present bidirectional translation algorithms between such representations as well as the necessary and sufficient conditions for translation convergence. Lastly, we demonstrate our action scheduling BT architecture showcasing the aforementioned caging scenarios, as well as other examples that show how BTs can be interfaced with other high level planners.

    Microstructure of plasma sprayed Al2O3-3wt%TiO2 coating using freeze granulated powder2016Inngår i: Journal of Materials Science and Chemical Engineering, ISSN 2327-6045, Vol. 4, nr 7, 8-14 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study is aiming at controlling the microstructure of plasma sprayed Al2O3-TiO2 composite coatings using freeze granulated powders. As sprayed and sintered Al2O3 + 3wt%TiO2 powders were air plasma sprayed with industry process parameters and compared with a commercial powder. The resulting coatings were investigated with respect to powder flowability, porosity and microstructure of the granules. The results showed that microstructure and melting fraction in the coatings could be tailored with the freeze granulation process and heat treatment conditions.

    Three new antisera with high sensitivity to ecdysone, 3-dehydroecdysone and other A-ring derivatives: Production and characterization1995Inngår i: European Journal of Entomology, ISSN 1210-5759, E-ISSN 1802-8829, Vol. 92, nr 1, 75-79 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Three new antisera have been produced in rabbits immunized with E-2/3-hemisuccinate conjugates. In a competitive enzyme immunoassay (EIA) with 20-ecdysone-peroxidase as a tracer, the antisera exhibit high specificity towards the side chain of the ecdysone (E) molecule. Modifications of the A-ring do result in no or small changes of sensitivity. One antiserum (RUD-2) allows the direct quantification of total ecdysteroids in samples containing E and 3-dehydroecdysone in varying ratios, without further sophisticated sample treatment. At least one of the other antisera allows the direct quantification of mixtures of E and 25-deoxyecdysone (RUD-1). Thus, these antisera may be a useful tool in studying molting control in arthropods.

    This paper presents an analysis of how leading Swedish historian and history didactical researcher Klas-Göran Karlsson presents the concept of historical consciousness in some of his most recent publications and seeks to analytically deconstruct his view of the concept. The study finds that Karlsson presents definitions of the concept that may not be compatible to each other. Using this result, the paper then tries to present and argue a view of the concept that harmonises with the one presented by Karlsson.

    Abstract [en]

    This is a study of a small runestone material from the Selaön Island in Lake Mälaren. As an island material, the inscriptions are set apart from their surroundings. They link in with common traits among decorated 11th runestones, but also with the characteristic breadth of middle-sized and well-defined materials. This local diversity may nevertheless be seen as a characteristic in itself of the larger Lake Mälaren area: this region is partly built from local nodes united by the lake. Based on the study three research fields are identified: 1) small-scale runestone geography and chronology, 2) the non-banal and complex relationship between design, text and ornament, 3) a dimension of intent characteristic of Selaön, that is, a local sincerity in the commemorative inscriptions. Micro-geography, complex design and mindset are thus suggested as new fields for a cognitively more rewarding contextual research into the runestone vogue in the Lake Mälaren area.

    Deconstructing Karlsson, part 1: Historical consciousness2017Inngår i: Historical Encounters: A journal of historical consciousness, historical cultures and history education, E-ISSN 2203-7543, Vol. 4, nr 2, 1-10 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents an analysis of how leading Swedish historian and history didactical researcher Klas-Göran Karlsson presents the concept of historical consciousness in some of his most recent publications and seeks to analytically deconstruct his view of the concept. The study finds that Karlsson presents definitions of the concept that may not be compatible to each other. Using this result, the paper then tries to present and argue a view of the concept that harmonises with the one presented by Karlsson.

    Hållbar gruvnäring: nordisk kunskap, god praxis och kunskapsluckor2016Rapport (Annet vitenskapelig)
    Abstract [sv]

    SusMinNor–projektet är ett samarbete mellan Finska Lapplands Förbund,Lapplands Universitet (Rovaniemi), och Luleå tekniska universitet.Projektet har två huvudsakliga målsättningar – att främja gränsöverskridandesamverkan kring hållbar gruvnäring i Interreg Nord-området,och att samla och syntetisera viktiga forskningsresultat från i huvudsakde samhällsvetenskapliga disciplinerna, särskilt kring konsekvenser avgruvnäring och synergier mellan gruvnäring och samhällen i nordligasteEuropa. Projektet finansieras av Interreg Nord och genomförs underperioden 2015-2016.Inom ramen för projektet har en forskningsworkshop genomförts iHaparanda, Sverige i april 2016 samt ett slutseminarium som genomfördesden 21 september 2016 i Rovaniemi, Finland. Projektet har mynnat ut iföreliggande syntesrapport som belyser de huvudsakliga teman som forskningenkring hållbar gruvnäring i norra Finland och Sverige har adresserat,samt identifierar god praxis och kunskapsluckor i litteraturen.En genomgång av viktiga internationella initiativ kring hållbar gruvnäringhar gjorts för att möjliggöra jämförelser mellan frågeställningarsom undersökts i Finland och Sverige. Sådana undersökningar och til�-lämpningar av deras resultat i utvecklingsländer skiljer sig på ett betydandesätt från de behov som finns i Finland och Sverige, men teman som”stakeholder engagement” strategier (d.v.s. hur intressenter och sakägarebemöts) samt social hållbarhet är viktiga även i de nordiska länderna.Trots viktiga skillnader finns ofta också möjligheter till lärande av internationellaerfarenheter.

    The Impact of Maintenance 4.0 and Big Data Analytics within Strategic Asset Management2017Inngår i: MPMM 2016, Maintenance, Performance, Measurement & Management: conference proceedings / [ed] Diego Galar, Dammika Seneviratne, Luleå: Luleå University of Technology, 2017, 96-103 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The latest industrial revolution is manifested by smart and networking equipment. Realizing the full value of these machineries, and other business assets, has become increasingly important. Strategic asset management faces managerial, technical as well as methodological challenges, of which some could be reduced or overcome by applying technological solutions such as Internet of things, cloud computing, cyber-physical systems and big data analytics. This paper outlines the impact of the emerging technologies in the area of strategic management with special emphasis on the analytics as service provider for the maintenance functions.

    Barriers and facilitators for BIM use among Swedish medium-sized contractors: We wait until someone tells us to use it2017Inngår i: Visualization in Engineering, ISSN 2213-7459, Vol. 5, nr 3, 1-12 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The pace of diffusion of BIM (Building Information Modelling) use is considered to increase with governmentalinitiatives in which public clients in countries like Finland, Singapore, United Kingdom, and Sweden begin requiring BIM as apart of the project delivery. Currently, larger contractor firms use BIM to a certain extent. However, BIM use by mid-sizedcontractor firms (that is, firms with 50–500 employees that can successfully compete with larger contractors on projects costinga maximum of 50 million Euros) is relatively unknown. Hence, the aim of the paper is to explore current use and perceivedconstraints and driving forces of BIM-implementation with respect to mid-sized contractors.

    Methods: A mixed method approach was applied, and data was collected through an interview study and a survey involvingchief executive officers or their closest sub-ordinates in mid-sized contractor firms in Sweden. The survey was based on atechnology-, organization-, and environment framework that is used in information systems research to study the use of inter-organizational information systems. The total population of firms in the survey corresponded to 104. The study presented thepreliminary results based on 32 answers (with a 31% response rate).

    Results: Fifty-eight percent of the surveyed respondents stated that they had been involved in a project in which BIM wasused in some manner. The most commonly used application included visualization, which also facilitates coordination andcommunication. The biggest perceived constraints involved partners that did not use BIM, lack of demand from clients, andthe absence of internal demand in the company. With respect tothe two last obstacles, significant differences existedbetween users and non-users. The most common perceived driving forces included the fact that BIM is perceived as ameans to follow technical development and that BIMprovides competitive advantages to the company.

    Conclusions: It is concluded that the main driver responsible for BIM-implementation is mainly determined by anindividual’s subjective positive or negative evaluation of BIM, instead of external pressure from clients and partners or by theinternal capacity and knowledge to use BIM.

    An ecosystem perspective on asset management information2017Inngår i: MPMM 2016, Maintenance, Performance, Measurement & Management: conference proceedings / [ed] Diego Galar, Dammika Seneviratne, Luleå: Luleå University of Technology, 2017, 69-75 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Big Data and Internet of Things will increase the amount of data on asset management exceedingly. Data sharing with an increased number of partners in the area of asset management is important when developing business opportunities and new ecosystems. An asset management ecosystem is a complex set of relationships between parties taking part in asset management actions. In this paper, the current barriers and benefits of data sharing are identified based on the results of an interview study. The main benefits are transparency, access to data and reuse of data. New services can be created by taking advantage of data sharing. The main barriers to sharing data are an unclear view of the data sharing process and difficulties to recognize the benefits of data sharing. For overcoming the barriers in data sharing, this paper applies the ecosystem perspective on asset management information. The approach is explained by using the Swedish railway industry as an example.

    Officials Reflections about Health Promoting Factors among Newly Arrivals: An Introductory Analysis2017Inngår i: International Journal of Community & Family Medicine, ISSN 2456-3498, Vol. 2, nr 1, IJCFM-124Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Resulting from conflicts, millions of peoples have been forced to leave their countries of origin. In Sweden, the Employment Agency is responsible for making decisions of immigrants’ residence in municipalities and in co-operation with these allow the immigrants’ establishment in the society. Preventive interventions among migrants and refugees, and health interventions in heterogeneous populations show that increased participation in society has positive imprints on health development. A new country includes getting acquaintance with non-familiar cultures. For example, other expectations on rules of gender, sickness, and illness. Recent years the low density populated areas in northern Sweden have received a high number of refugees in comparison with their population size. The purpose of this study was to explore how officials the Employment Agency and a selection of municipalities reflect over and define health promoting factors in their meetings with newly arrived.

    Methods: All officials (N 68) in one of the four northern counties were invited to recording their reflections on health promoting factors close to their meetings with newly arrived. The officials recorded how they defined health promoting factors according to the Audit method. The data collection of experiences of importance considering health promotion and social determinants was collected by five focus group interviews with twenty-three officials.

    Results: This study showed that the officials defined access to the health care, participation in the society, and sufficient collaboration between the authorities for not losing valuable time during the establishment period as imported factors for their clients’ opportunities for health. The officials take power among males for given, while they more often reflected over lack of power among women. However, the Swedish ideal of gender as equal quite often a challenge the newly arrivals.

    Results from Geant4 calculations of energy deposition from gamma- and neutron radiation emitted from selected cases of used boiling water reactor nuclear fuel assemblies in a KBS-3 type deep geological repository2017Dataset
    Abstract [en]

    Monte Carlo calculations, using the Geant4 framework version 10.02, of energy deposition from gamma- and neutron radiation emitted from boiling water reator (BWR) fuel assemblies in a KBS-3 type deep geological repository for used nuclear fuel have been performed. This dataset contains the results of the calculations. Three fuel rods were arbitrarily selected as source rods for 662 keV and 2.75 MeV gamma- and neutron radiation, respectively. For each of the six cases, the energy deposited in a 3-dimensional (x,y,z) mesh with 1 cm resolution was calculated and tallied as function of the type of particle that deposited the energy.

    Teoribaserad utvärdering av lämplighetsbedömning: Rapport från försöksverksamhet med lämplighetsbedömning vid antagning till lärar- och förskollärarutbildning2017Rapport (Annet vitenskapelig)
    Abstract [sv]

    Föreliggande rapport är en utvärdering av den försöksverksamhet med lämplighetsbedömning vid antagning till lärar- och förskollärarutbildning som bedrivits vid Jönköping University på uppdrag av Universitets- och högskolerådet.

    Försöksverksamheten har varit baserad på ett särskilt regeringsbeslut grundat i antaganden om lämplighetsbedömningens mening och eventuella effekter. Därför är denna utvärdering teoribaserad, det vill säga att den utgår från antaganden om lämplighetsbedömningens funktion givet en viss verksamhetslogik.

    Utvärderingen är genomförd på lokal nivå av undertecknad och i nära anslutning till genomförd lämplighetsbedömning. Underlaget består främst av inblandade parters upplevelser i kombination med utfall under ansökningsförfarandet. Sammantaget kombineras processutvärderande delar med mer effektutvärderande resonemang. En mer omfattande utvärdering kommer att genomföras av ansvarig myndighet, Universitets- och högskolerådet.

    Resultat talar för att krav på visad lämplighet kan ha effekter på sökandes agerande under ansöknings- och antagningsfaser. Lämplighetsbedömningen har först och främst fungerat som ett prov på sökande motivation för att bli antagen till utbildningen. Kravet som sådant – att sökande måste uppvisat lämplighet för behörighet till utbildningen – har förmodligen haft störst effekt, även om behållningen av självbedömning och andra aspekter inte bör underskattas.

    Välkommen att läsa utvärderingen i sin helhet för en mer utvecklad redogörelse av ovanstående.

    Measurement of the t(t)over-bar production cross-section using e mu events with b-tagged jets in pp collisions at root s=13 TeV with the ATLAS detector2016Inngår i: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 761, 136-157 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    his paper describes a measurement of the inclusive top quark pair production cross-section (sigma(t (t) over bar)) with a data sample of 3.2 fb(-1) of proton-proton collisions at a centre-of-mass energy of root s = 13 TeV, collected in 2015 by the ATLAS detector at the LHC. This measurement uses events with an opposite-charge electron-muon pair in the final state. Jets containing b-quarks are tagged using an algorithm based on track impact parameters and reconstructed secondary vertices. The numbers of events with exactly one and exactly two b-tagged jets are counted and used to determine simultaneously sigma(t (t) over bar) and the efficiency to reconstruct and b-tag a jet from a top quark decay, thereby minimising the associated systematic uncertainties. The cross-section is measured to be: s(t (t) over bar)= 818 +/- 8 (stat) +/- 27 (syst) +/- 19 (lumi) +/- 12 (beam) pb, where the four uncertainties arise from data statistics, experimental and theoretical systematic effects, the integrated luminosity and the LHC beam energy, giving a total relative uncertainty of 4.4%. The result is consistent with theoretical QCD calculations at next-to-next-to-leading order. A fiducial measurement corresponding to the experimental acceptance of the leptons is also presented.

    Measurement of the total cross section from elastic scattering in pp collisions at root s=8 TeV with the ATLAS detector2016Inngår i: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 761, 158-178 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A measurement of the total ppcross section at the LHC at root s = 8TeV is presented. An integrated luminosity of 500 mu b(-1) was accumulated in a special run with high-beta* beam optics to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable t. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the -t range from 0.014 GeV2 to 0.1 GeV2 to extrapolate t -> 0, the total cross section, sigma(tot)( pp -> X), is measured via the optical theorem to be sigma(tot)(pp -> X) = 96.07 +/- 0.18 (stat.) +/- 0.85 (exp.) +/- 0.31 (extr.) mb, where the first error is statistical, the second accounts for all experimental systematic uncertainties and the last is related to uncertainties in the extrapolation t -> 0. In addition, the slope of the exponential function describing the elastic cross section at small t is determined to be B = 19.74 +/- 0.05 (stat.) +/- 0.23 (syst.) GeV-2.

    Measurement of the top quark mass in the t(t)over-bar -> dilepton channel from root s=8TeVATLAS data2016Inngår i: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 761, 350-371 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A search has been made for supersymmetry in a final state containing two photons and missing transverse momentum using the ATLAS detector at the Large Hadron Collider. The search makes use of 3.2 fb−1 of proton-proton collision data collected at a centre-of-mass energy of 13 TeV in 2015. Using a combination of data-driven and Monte-Carlo-based approaches, the Standard Model background is estimated to be 0.27+0.22−0.10 events. No events are observed in the signal region; considering the expected background and its uncertainty, this observation implies a model-independent 95 % CL upper limit of 0.93 fb (3.0 events) on the visible cross section due to physics beyond the Standard Model. In the context of a generalized model of gauge-mediated supersymmetry breaking with a bino-like next-to-lightest supersymmetric particle, this leads to a lower limit of 1650 GeV on the mass of a degenerate octet of gluino states, independent of the mass of the lighter bino-like neutralino.

    Perceptions of sustainability and functional aspects on liquid carton board packaging materials versus competing materials for juice applications in Sweden2015Inngår i: Beverages, E-ISSN 2306-5710, Vol. 1, nr 3, 194-203 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This research explores the downstream perceptions of liquid carton board versus competing materials in packaging applications for juice. The methodology used is focus groups. The context is sustainability and functional performance, and related potential implications for the beverage industry value chain. The purpose is to get a deeper insight and understanding of functionality in relation to juice beverage packaging. The results confirm that there is no optimal packaging for every juice product, but a multitude, depending on the distribution channel, retail outlet, customer preferences, and context of consumption. There are some general packaging preferences, but the main deciding criteria for purchase seem to be the product characteristics in terms of quality, taste, brand, price and shelf life. For marketing reasons, packaging has to be adopted to the product and its positioning, liquid carton board packaging seem to have some functional advantages in distribution and is considered as sustainable and functional among many consumers. Major drawbacks seem to be shape limitations, lack of transparency, and lack of a “premium look”. To improve packaging performance and avoid sub-optimization, actors in the beverage industry value chain need to be integrated in development processes.

    Microfluidic based isolation of circulating tumor cells from whole blood for cancer diagnostics2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Detection of circulating tumor cells (CTC) in peripheral blood is indicative of early recognition of tumor progression and such an important biomarker for early diagnosis, staging, monitoring and prognosis of cancer. However, CTC are found in very low concentrations and reliable isolation of these rare cells is challenging. Microfluidics enables precise manipulation of fluids and cells and is ideal for cell sorting methods for clinical diagnostics. The thesis contributes towards the development of microfluidic based CTC isolation methods from peripheral blood. The methods are based on size and immunoaffinity. The first part of the thesis describes the phenomenon of inertial focusing for size based cell separation at high throughputs. In paper 1, we demonstrate continuous filtration of leukocytes from diluted blood, with an efficiency of 78% at a flow rate of 2.2ml/min. In the paper 2, separation of total and subpopulation of leukocytes with a purity of 86% for granulocytes and 91% for lymphocytes is demonstrated. Furthermore, cancer cells spiked into whole blood could be separated at a yield of 88%. Finally, in paper 3 and 4 we unravel parts of the unexplored elasto-inertial microfluidics and was utilized to precisely focus the cells, as part of an integrated optofluidic micro flow cytometer device, capable to simultaneously measure fluorescence and scattering of cells and particles at a rate of 2500 particles/sec (paper 4). Second part of the thesis focuses on acoustophoresis. In (paper 5), a multifunctional acoustic microdevice was developed for isolation of cancer cells from red blood cells with a separation efficiency of 92.4% and trapping efficiency of 93%. In (paper 6), microbubbles activated acoustic cell sorter was developed for affinity based cell separation. As a proof of principle, cancer cells in a suspension were separated at an efficiency of 75%. In the third part, using cellulose nano fibrils (paper 7), we demonstrate efficiently capture and release of cancer cells at a release efficiency of 95%. Finally, a novel, single step self-assembly of spider silk proteins is introduced inside microfluidic channels for effective capture of cancer cells with 85% capture efficiency and subsequent release of captured cells with 95% release efficiency (paper 8). The novel recombinant silk modified microfluidic device was validated using pancreatic cancer patients. In summary, we have developed different microfluidic based isolation technologies for the capture and characterization of CTC.

    An organic mixed ion-electron conductor for power electronics2015Inngår i: Advanced science, E-ISSN 2198-3844, 1500305Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A mixed ionic–electronic conductor based on nanofibrillated cellulose composited with poly(3,4-ethylene-dioxythio­phene):­poly(styrene-sulfonate) along with high boiling point solvents is demonstrated in bulky electrochemical devices. The high electronic and ionic conductivities of the resulting nanopaper are exploited in devices which exhibit record values for the charge storage capacitance (1F) in supercapacitors and transconductance (1S) in electrochemical transistors.

    Search for high-mass new phenomena in the dilepton final state using proton-proton collisions at root s=13 TeV with the ATLAS detector2016Inngår i: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 761, 372-392 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A search is conducted for both resonant and non-resonant high-mass new phenomena in dielectron and dimuon final states. The search uses View the MathML source3.2fb−1 of proton–proton collision data, collected at View the MathML sources=13TeV by the ATLAS experiment at the LHC in 2015. The dilepton invariant mass is used as the discriminating variable. No significant deviation from the Standard Model prediction is observed; therefore limits are set on the signal model parameters of interest at 95% credibility level. Upper limits are set on the cross-section times branching ratio for resonances decaying to dileptons, and the limits are converted into lower limits on the resonance mass, ranging between 2.74 TeV and 3.36 TeV, depending on the model. Lower limits on the ℓℓqqℓℓqq contact interaction scale are set between 16.7 TeV and 25.2 TeV, also depending on the model.

    Emission of methane from northern lakes and ponds2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Northern lakes and ponds are abundant and emit large amounts of the potent climate forcer methane to the atmosphere at rates prone to change with amplified Arctic warming. In spite of being important, fluxes from surface waters are not well understood. Long-term measurements are lacking and the dominant and irregular transport mode ebullition (bubbling) is rarely quantified, which complicate the inclusion of lakes and ponds in the global methane budget. This thesis focuses on variations in emissions on both local and regional scales. A synthesis of methane fluxes from almost all studied sites constrains uncertainties and demonstrates that northern lakes and ponds are a dominant source at high latitudes. Per unit area variations in flux magnitudes among different types of water bodies are mainly linked to water depth and type of sediment. When extrapolated, total area is key and thus post-glacial lakes dominate emissions over water bodies formed by peat degradation or thermokarst processes. Further, consistent multiyear measurements in three post-glacial lakes in Stordalen, northern Sweden, reveal that seasonal ebullition, primarily driven by fermentation of acetate, can be predicted by easily measured parameters such as temperature and heat energy input over the ice-free season. Assuming that most water bodies respond similarly to warming, this thesis also suggests that northern lakes and ponds will release substantially more methane before the end of the century, primarily as a result of longer ice-free seasons. Improved uncertainty reductions of both current and future estimates rely on increased knowledge of landscape-level processes related to changes in aquatic systems and organic loading with permafrost thaw, as well as more high-quality measurements, seldom seen in contemporary data. Sampling distributed over entire ice-free seasons and across different depth zones is crucial for accurately quantifying methane emissions from northern lakes and ponds.

    The hidden life of plants: fine root dynamics in northern ecosystems2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Fine roots constitute a large part of the primary production in northern (arctic and boreal) ecosystems, and are key players in ecosystem fluxes of water, nutrients and carbon. Data on root dynamics are generally rare, especially so in northern ecosystems. However, those ecosystems undergo the most rapid climatic changes on the planet and a profound understanding of form, function and dynamics of roots in such ecosystems is essential.

    This thesis aimed to advance our knowledge about fine root dynamics in northern ecosystems, with a focus on fine root phenology in natural plant communities and how climate change might alter it. Factors considered included thickness and duration of snow cover, thawing of permafrost, as well as natural gradients in temperature. Experiments and observational studies were located around Abisko (68°21' N, 18°45' E), and in a boreal forest close to Vindeln (64°14'N, 19°46'E), northern Sweden. Root responses included root growth, total root length, and root litter input, always involving seasonal changes therein, measured with minirhizotrons. Root biomass was also determined with destructive soil sampling. Additionally, aboveground response parameters, such as phenology and growth, and environmental parameters, such as air and soil temperatures, were assessed.

    This thesis reveals that aboveground patterns or responses cannot be directly translated belowground and urges a decoupling of above- and belowground phenology in terrestrial biosphere models. Specifically, root growth occurred outside of the photosynthetically active period of tundra plants. Moreover, patterns observed in arctic and boreal ecosystems diverged from those of temperate systems, and models including root parameters may thus need specific parameterization for northern ecosystems. In addition, this thesis showed that plant communities differ in root properties, and that changes in plant community compositions can thus induce changes in root dynamics and functioning. This underlines the importance of a thorough understanding of root dynamics in different plant community types in order to understand and predict how changes in plant communities in response to climate change will translate into root dynamics. Overall, this thesis describes root dynamics in response to a variety of factors, because a deeper knowledge about root dynamics will enable a better understanding of ecosystem processes, as well as improve model prediction of how northern ecosystems will respond to climate change.

    Cryogenic soil processes in a changing climate2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in combination with other cryogenic disturbance processes may play a profound role in controlling the carbon balance of the arctic soil. Conditions for cryogenic soil processes are predicted to dramatically change in response to the ongoing climate warming, but little is known how these changes may affect the ability of arctic soils to accumulate carbon. In this thesis, I utilize a patterned ground system, referred to as non-sorted circles, as experimental units and quantify how cryogenic soil processes affect plant communities and carbon fluxes in arctic soils. I show that the cryoturbation has been an important mechanism for transporting carbon downwards in the studied soil over the last millennia. Interestingly, burial of organic material by cryoturbation appears to have mainly occurred during bioclimatic events occurring around A.D. 900-1250 and A.D. 1650-1950 as indicated by inferred 14C ages. Using a novel photogrammetric approach, I estimate that about 0.2-0.8 % of the carbon pool is annually subjected to a net downward transport induced by the physical motion of soil. Even though this flux seems small, it suggests that cryoturbation is an important transporter of carbon over centennial and millennial timescales and contributes to translocate organic matter to deeper soil layers where respiration proceeds at slow rates. Cryogenic processes not only affect the trajectories of the soil carbon, but also generate plant community changes in both species composition and abundance, as indicated by a conducted plant survey on non-sorted circles subjected to variable differential frost heave during the winter. Here, disturbance-tolerant plant species, such as Carex capillaris and Tofieldia pusilla, seem to be favoured by disturbance generated by the differential heave. Comparison with findings from a previous plant survey on the site conducted in the 1980s suggest that the warmer temperatures during the last decades have resulted in decreased differential heave in the studied non-sorted circles. I argue that this change in cryogenic activity has increased abundance of plants present in the 1980s. The fact that the activity and function of the non-sorted circles in Abisko are undergoing changes is further supported by their contemporary carbon dioxide (CO2) fluxes. Here, my measurements of CO2 fluxes suggest that all studied non-sorted circles act as net CO2 sources and thus that the carbon balance of the soils are in a transition state. My results highlight the complex but important relationship between cryogenic soil processes and the carbon balance of arctic soils.

    Mosses as mediators of climate change: implications for tree seedling establishment in the tundra2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Alpine and arctic tree line expansion depends on the establishment of tree seedlings above the current tree line, which is expected to occur with climate warming. However, tree lines often fail to respond to higher temperatures. Other environmental factors are therefore likely important for tree seedling establishment. Above the tree line, establishing seedlings encounter existing vegetation such as bryophytes, which often dominate in arctic and alpine tundra. Bryophytes modify their environment in various ways and may mediate climate change effects on establishing tree seedlings, and with that tree line expansion. The aim of this thesis was to understand if and how the environment, in particular bryophytes, mediates the impact of climate change on tree seedling establishment at the alpine and arctic tree line. This was explored by reviewing literature on tree seedling establishment at alpine and arctic tree lines globally. In addition, tree seedling survival and growth of Betula pubescens and Pinus sylvestris were assessed experimentally. Here, individuals were planted into mono-specific mats of different bryophytes species and exposed to warming and different precipitation regimes. The literature review revealed that besides from temperature, tree seedling establishment is affected by a wide range of abiotic and biotic factors including water, snow, nutrients, light, disturbance and surrounding vegetation. Furthermore the review revealed that for example vegetation can change tree seedling responses to climate change. The experiments showed that especially tree seedling survival was adversely affected by the presence of bryophytes and that the impacts of bryophytes were larger than those of the climate treatments. Seedling growth, on the other hand, was not hampered by the presence of bryophytes, which is in line with earlier findings that seedling survival, growth and seed germination do not respond similarly to changes in environmental conditions. Moreover, we found several indications that vegetation above the tree line, including bryophytes, mediated tree seedling responses to warming and precipitation or snow cover. This thesis shows that temperature alone should not be used to predict future tree seedling establishment above the alpine and arctic tree line and that extrapolations from climate envelope models could strongly over or under estimate tree line responses to warming. This underlines the value of multi-factorial studies for understanding the interplay between warming and other environmental factors and their effects on tree seedling establishment across current tree lines.

    Primary energy use of residential buildings - implications of materials, modelling and design approaches2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Buildings can play an essential role in the transition to a sustainable society. Different strategies, including improved energy efficiency in buildings, substitution of carbon intensive materials and fuels, efficient energy supply among others can be employed for this purpose. In this thesis, the implications of different insulation materials, modelling and design strategies on primary energy use of residential buildings are studied using life cycle and system perspective. Specifically, the effects of different insulation materials on production primary energy and CO2 emission of buildings with different energy performance are analysed. The results show that application of extra insulation materials to building envelope components reduces the operating primary energy use but more primary energy is required for the insulation material production. This also slightly increases the CO2 emissions from material production. The increases in primary energy use and CO2 emissions are mainly due to the variations in the quantities, types and manufacturing processes of the insulation materials. Thus, choice of renewable based materials with energy efficient manufacturing is important to reduce primary energy use and GHG emissions for building material production.

    Uncertainties related to building modelling input parameters and assumptions and how they influence energy balance calculations of residential buildings are explored. The implications on energy savings of different energy efficiency measures are also studied. The results show that input data and assumptions used for energy balance simulations of buildings vary widely in the Swedish context giving significant differences in calculated energy demand for buildings. Among the considered parameters, indoor air temperature, internal heat gains and efficiency of ventilation heat recovery (VHR) have significant impacts on the simulated building energy performance as well as on the energy efficiency measures. The impact of parameter interactions on calculated space heating of buildings is rather small but increases with more parameter combinations and more energy efficient buildings. Detailed energy characterisation of household equipment and technical installations used in a building is essential to accurately calculate the energy demand, particularly for a low energy building.

    The design and construction of new buildings present many possibilities to minimise both heating and cooling demands over the lifecycle of buildings, and also in the context of climate change. Various design strategies and measures are analysed for buildings with different energy performance under different climate scenarios. These include household equipment and technical installations based on best available technology, bypassing the VHR unit, solar shading of windows, combinations of window u- and g-values, different proportions of glazed window areas and façade orientations and mechanical cooling. The results show that space heating and cooling demands vary significantly with the energy performance of buildings as well as climate scenarios. Space heating demand decreases while space cooling demand and the risk of overheating increase considerably with warmer climate. The space cooling demand and overheating risk are more significant for buildings with higher energy performance. Significant reductions are achieved in the operation final energy demands and overheating is avoided or greatly reduced when different design strategies and measures are implemented cumulatively under different climate change scenarios.

    The primary energy efficiency of heat supply systems depends on the heat production technology and type of fuel use. Analysis of the interaction between different design strategies and heat supply options shows that the combination of design strategies giving the lowest primary energy use for space heating and cooling varies between heat supply from district heating with combined heat and power (CHP) and heat only boilers (HOB). The primary energy use for space heating is significantly lower when the heat supply is from CHP rather than HOB. Operation primary energy use is significantly reduced with slight increase in production primary energy when the design strategies are implemented. The results suggest that significant primary energy reductions are achievable under climate change, if new buildings are designed with appropriate strategies.

    Särredovisning av kostnader i kommunal verksamhet: Rapport från sju kommuner med erfarenhet av att rapportera om kostnader för olika kalkylobjekt2017Rapport (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    Den här rapporten handlar om särredovisning av kostnader i sju svenska kommuner. En rad olika aktörer kan vara intresserade av en verksamhets kostnader, bland annat Konkurrensverket för att avgöra om en organisation gör sig skyldig till över- eller underprissättning. Även myndigheter som Statistiska centralbyrån (SCB), kommunpolitiker och tjänstemän samt media ställer frågor om kostnaden för specifika kalkylobjekt (till exempel processer, brukarkategorier eller produkter). Ofta gäller det något som inte följs upp rutinmässigt. Hur besvaras sådana frågor?

    Vi har undersökt detta genom en explorativ studie i sju svenska kommuner. Fokus i rapporten ligger på kostnadssammanställningar som görs i tillägg till bokföringens löpande uppföljning. Sådan särredovisning kan både göras ad hoc (för att besvara en unik fråga) och löpande.

    Studiens syfte är att beskriva hur sju svenska kommuner med stor erfarenhet av uppföljning och analys, hanterar frågor om kostnader för kalkylobjekt som inte redan är föremål för löpande särredovisning samt identifiera resurser och kompetenser som krävs för att lyckas med detta. Vi avgränsar oss alltså till ett antal ”goda exempel”, snarare än att ge en representativ bild av särredovisning i svenska kommuner. Vi fokuserar produktionen av kostnadsinformationen och analyserar inte konsekvenserna av att använda den.

    Kostnader särredovisas av olika anledningar. För att öka förståelsen av detta beskrivs tre situationer då kostnader för specifika kalkylobjekt efterfrågas: frågor internt från politiker och tjänstemän, frågor externt från myndigheter och andra granskande aktörer samt frågor från medborgare eller massmedia. Dessutom beskriver vi fem viktiga vägval som påverkar vilken precision som kan uppnås i särredovisningen. Dessa är hämtade från en tidigare rapport för Konkurrensverket (Olve och Petri, 2014), och handlar om hur kalkylobjekt definieras, hur data samlas in, vilket urval av kostnader som görs och hur samkostnader fördelas, samt hur kostnadsinformationen används.

    Resultaten visar att kommunerna kan göra avancerade kostnadskalkyler, men att sådana analyser är förknippade med resursanvändning bland såväl ekonomer som verksamhetspersonal. Om kostnadsinformationen inte är till nytta internt, kan det vara svårt att mobilisera intresse för att upprätta kalkylerna (i konkurrens med annan uppföljning som också efterfrågas). För kalkylobjekt som motsvarar konton i bokföringen, organisatoriska enheter eller leverantörer, kan fackekonomerna själva ta fram kostnadsinformation med hög precision. Men för mer verksamhetsnära kalkylobjekt (som produkter, processer och brukare) krävs ofta engagemang även från experter i verksamheten. Kostnadsinformationen som används internt ligger ofta till grund för styrningen och fokuserar därför ”påverkbara” kostnader snarare än full självkostnad. Utvecklingen mot större inslag av marknadslogik (så kallad New Public Management/NPM) har också påverkat uppföljningen. Gradvis har politikens och beställarnas fokus flyttats från kostnader i verksamheten, till det pris som betalas för den upphandlade verksamheten – oavsett om den levereras av en extern leverantör eller av den interna utförarorganisationen.

    Innovative system for the construction and management of student resisdences: Frameup system2016Inngår i: 19th IABSE Congress Report Stockholm 2016 / [ed] IABSE, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Sweden has a strong demand on the construction of student accommodations and consequently significant efforts have been taken to increase and streamline construction methods. In addition, the fluctuation on the number of students admitted at each year, in each university, lead to periods of house shortage or, in opposition to that, to eventual surplus on the housing market. For these reasons urges finding a fast execution process in construction to fulfil the market needs, together with a housing mechanism of control which balances the students’ needs with the housing availability. In this sense, the Frameup system arises as a solution to solve both problems by combining a modular construction with an innovative execution process.

    The FRAMEUP buildings uses a steel frame in combination with prefabricated 3D modules - fully equipped and suitable for student accommodations – which are assembled by starting from the roof to the 1st floor. The existence of the lifting system permits the erection of the building, promoting each time the building is lifted, a clearance of one-floor-height, at ground level, for the assembly of a new floor. The procedure is repeated several times, according to the number of floors, until the 1st floor of the building, the last floor of the execution sequence, is assembled.

    Alongside with its advantage on the fast execution, the Frameup system allows to efficiently increase or decrease the number of the floors and consequently its exchangeability with other buildings of same nature. Thus, assuming a net of FRAMEUP buildings at each university, its exchangeability system would create the necessary conditions so that the number of floors at each campus would follow the fluctuations of the students’ population among the different universities on different periods of time, so to suppress the needs for housing or to avoid the surplus on construction.

    To stay or not to stay. That is the question: beyond retirement: Stayers on the labour market2017Rapport (Annet vitenskapelig)
    Abstract [en]

    The research project addresses three main questions: Who are the persons that continue to work after “normal” retirement age? What are their motivations? What are the consequences for the individual and for society? To answer these questions we perform an analysis of external and internal factors affecting the choice to stay after 65 years on the labour market or to leave earlier. Among external factors we investigate are: The impact of the prevailing labour laws and regulations on senior citizens’ participation on the labour market ; The socio-economic factors that affect the likelihood to stay on the labour market after the age of 65 ; The impact of employers’ human resource strategies on the possibility for senior workers to remain on the labour market after the age of 65 years. We also analyse the the role of individ specific factors such as motivation and , personal traits but the outcome in terms of subjective well-being and health.

    Parents' performance in entrepreneurship as a "double-edged sword" for the intergenerational transmission of entrepreneurship2017Inngår i: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We investigate how perceived parents’ performance in entrepreneurship (PPE) affects the entrepreneurial career intentions of offspring. We argue that while perceived PPE enhances offspring’s perceived entrepreneurial desirability and feasibility because of exposure mechanisms, it weakens the translation of both desirability and feasibility into entrepreneurial career intentions due to upward social comparison mechanisms. Thus, perceived PPE acts as a double-edged sword for the intergenerational transmission of entrepreneurship. Our predictions are tested and confirmed on a sample of 21,895 individuals from 33 countries. This study advances the literature on intergenerational transmission of entrepreneurship by providing a foundation for understanding the social psychological conditions necessary for such transmission to occur.
