    Spatial and Dynamic Modelling of Flood Management Policies in the Upper Tisza2003Report (Refereed)
    Abstract [en]

    Flood management policy has been the subject of an international joint research

    project with the Upper Tisza in Hungary as its pilot study area. Design specications

    for a geographically explicit simulation model are presented. Potential flood

    management policies, based on surveys and interviews with stakeholders, are presented.

    Some experiments on an executable prototype of the simulation model are

    also reported on, where the consequences of flood management policies are investigated.

    Focus has been on nancial policy measures, mainly insurance. Besides

    more traditional evaluation of policy scenarios, the model incorporates adaptive

    optimisation functionality. The report incorporates three contributions:

    1. the insurance policy issue in Hungary is framed in the broader context of flood

    management

    2. the structuring of a flood risk policy model, capable of simulating flood failures

    and estimating the economic consequences

    3. reports from policy experiments performed on the implemented prototype

    flood risk policy model

    MicroWorlds as a Tool for Policy Making2001Conference paper (Refereed)
    Abstract [en]

    The Hungarian government is experiencing escalating costs for ood mitigation

    measures and for economical compensation to victims. In a joint

    research project between the International Institute of Applied System Analysis

    (IIASA) in Austria, Computer and System Science Department (DSV)

    in Sweden, and the Hungarian Academy of Science, the ooding problem of

    Upper Tisza in Hungary is investigated. A catastrophe simulation model has

    been implemented, where dierent policy options are tested and evaluated.

    We investigate how the willingness to buy insurance aects the results on

    the macro-level and on the micro-level.

    Applying the Consumat Model to Flood Management Policies2003In: Agent-based simulation, 2003Conference paper (Refereed)
    Abstract [en]

    The number and severity of weather related catastrophes is

    increasing. Economic losses from these catastrophes are

    escalating, mainly as a result of concentration of assets and

    population in high-risk areas. How to deal with these

    economic liabilities in a fair way at the level of the individual

    property owners is the focus of our research.

    As a case study we choose the Tisza, a river in Hungary that

    flows through one of the poorest agricultural regions of

    Europe that frequently floods. The use of a simulation model

    for evaluating alternative flood management policies is a

    natural choice, since it is impossible to predict the time,

    location and magnitude of a flood; historical data is of limited

    use when looking at the outcome of future policies. The

    behaviour of the river and the financial consequences are

    simulated on a year-by-year basis.

    Here we have extended the simulation model by using the

    Consumat approach to model the individual property owners.

    We compare the results with respect to wealth distribution in

    the case of Consumat agents and simple (non-Consumat)

    agents. In the Consumat case, the results show that system is

    more dynamic and more realistic.

    The Informed Gaze: On the Implications of ICT-Based Surveillance2013Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Information and communication technologies are not value-neutral. I examine two domains, public health surveillance and sustainability, in five papers covering: (i) the design and development of a software package for computer-assisted outbreak detection; (ii) a workflow for using simulation models to provide policy advice and a list of challenges for its practice; (iii) an analysis of design documents from three smart home projects presenting intersecting visions of sustainability; (iv) an analysis of EU-financed projects dealing with sustainability and ICT; (v) an analysis of the consequences of design choices when creating surveillance technologies. My contributions include three empirical studies of surveillance discourses where I identify the forms of action that are privileged and the values that are embedded into them. In these discourses, the presence of ICT entails increased surveillance, privileging technological expertise, and prioritising centralised forms of knowledge.

    Liminality and Disinhibition in Online Language Learning2011In: International Review of Research in Open and Distance Learning, ISSN 1492-3831, E-ISSN 1492-3831, Vol. 12, no 5, p. 25-37Article in journal (Refereed)
    Abstract [en]

    The aim of this paper is to bring theoretical concepts from other areas of scholarly research to bear on synchronous online education in a cross-disciplinary effort to shed light on what is going on by introducing systems of thought from other areas. The liminality and associated communitas which are found in synchronous online learning environments are examined for their possible consequences for learning in general and language learning in particular. Like computer-mediated communication, liminality has been associated with disinhibitory effects. Lack of excessive inhibition has been shown to have positive effects on second language production. The position of the online learner as “neither here nor there” or perhaps simultaneously both here and there is investigated and discussed.

    Efficient and Sustainable Risk Management in Large Project Portfolios2018In: Perspectives in Business Informatics Research: Proceedings / [ed] Jelena Zdravkovic, Jānis Grabis, Selmin Nurcan, Janis Stirna, Springer, 2018, p. 143-157Conference paper (Refereed)
    Abstract [en]

    In an ever-increasing competitive business environment, it has become increasingly important to be able to obtain efficient and sustainable business operations not only by efficient core procedures but also by being able to minimise losses incurred by risk taking. The latter by handling both operational risks and financial risks in a unified model. This is important not least in businesses that handle sets of simultaneous large projects, which is the topic of risk handling in project portfolios. In this paper, we present a novel method for business risk handling for project portfolios under strong uncertainty. The method is based on event trees representing each adverse consequence modelled, together with mitigation costs and effects. The aggregation of all consequences for all projects together constitutes the risk portfolio for the business. This method is used in one of Sweden’s largest manufacturing enterprises having a vast portfolio of projects in the form of ongoing tenders for orders.

    Space-Time Trade-Off in Decision Analysis Software2018In: New Trends in Intelligent Software Methodologies, Tools and Techniques / [ed] Hamido Fujita, Enrique Herrera-Viedma, IOS Press, 2018, p. 251-258Conference paper (Refereed)
    Abstract [en]

    In decision analysis, there are several problems with the assignment of precise numbers to decision components, such as probabilities, values and weighs. These can very seldom realistically be estimated. Therefore, various alternative approaches have been suggested over the years, such as interval, capacity and ranking models. The more general of these are however problematical from several computational viewpoints and in this article, we deal with the server-side issues when converting the application from a stand-alone PC program to a server-client decision analytical software. On a server with a large number of users, space requirements become paramount as opposed to a single user on a PC. On a PC, matrices can be explicitly stored in memory, while on a server, to save space, matrices might have to be stored in an implicit (compacted) way, leading to space-time trade-offs.

    A Multi-Stakeholder Approach to Energy Transition Policy Formation in Jordan2018In: Group Decision and Negotiation in an Uncertain World: Proceedings / [ed] Ye Chen, Gregory Kersten, Rudolf Vetschera, Haiyan Xu, Cham: Springer, 2018, p. 190-202Conference paper (Refereed)
    Abstract [en]

    We present the method used in an ongoing project in Jordan for a multi-stakeholder, multi-criteria problem of formulating a nationwide energy strategy for the country for the next decades. The Jordanian government has recognized the need for energy transition and the main goal of the energy strategy is to provide a reliable energy supply by increasing the share of local energy resources in the energy mix, while reducing dependency on imported fossil fuels, by diversifying energy resources, also including renewable energy sources, nuclear and shale oil, and by enhancing environmental protection. There were strong incentives for a collaborative approach, since the ways in which different stakeholder groups subjectively attach meanings to electricity generation technologies are recognized as important issues shaping the attainment of energy planning objectives. To understand the meaning of these constructs, we are using a multi-stakeholder multi-criteria decision analysis (MCDA) approach to elicit criteria weights and valuations.

    Utilizing Surrogate Numbers for Probability Elicitation2018In: Decision Making / [ed] Fausto Pedro García Márquez, Alberto Pliego Marugán, Mayorkinos Papaelias, IntechOpen , 2018, p. 39-56Chapter in book (Other academic)
    Abstract [en]

    Comparatively few of the vast number of suggested decision-analytical methods have been widely spread in actual practice. The majority of those methods call for exact and accurate numbers as input, which could be one of several reasons for this lack of actual use; people frequently seem to be unfamiliar with, or reluctant to express those, in a sense, “true” values required. Many alternative methods to resolve this complication have been suggested over the years, including procedures for dealing with incomplete information. One way, which has proliferated for a while, is to introduce so-called surrogate numbers in the form of ordinal ranking methods for multi-criteria weights. In this chapter, we show how those can be adapted for use in probability elicitation. Furthermore, when decision-makers possess more information regarding the relative strengths of probabilities, that is, some form of cardinality, the input information to ordinal methods is sometimes too restricted. Therefore, we suggest a testing methodology and analyze the relevance of a set of cardinal ordering methods in addition to the ordinal ones.

    Hazards and quality control in humanitarian demining2018In: International Journal of Quality & Reliability Management, ISSN 0265-671X, E-ISSN 1758-6682, Vol. 35, no 4, p. 897-913Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to discuss the adequacy of International Mine Action Standards 09.20 (IMAS 09.20) and the used standards ISO 2859 in the context of demining. Design/methodology/approach: The authors show how the actual quality level acceptable quality limit (AQL) significantly affects the average total quality cost for one lot with a single sampling plan and, consequently, the average total quality cost, and as AQL increases, the cost of rejecting a lot and the cost of sampling increase. Findings: The sampling plans for demining are not always optimal given economical and other concerns and that other mechanisms should be considered. Practical implications: Addressing opportunity costs for adopting wide samplings plans instead of clearing uncleared land per default, as well as balancing producer and consumer consequences seems, therefore, to be highly relevant from a socio-economical perspective. Originality/value The general understanding of quality management and the systems involved are limited within the mine action sector. IMAS and most national mine action standards provide only a fairly narrow description of the issue. This implies that the field is missing opportunities to achieve efficiency and effectiveness, as well as to learn from and improve upon past experiences. The authors demonstrate herein that sampling provides little additional confidence as to whether a particular area is free from explosive hazards and substantial savings can be made compared to the current practice.

    You are Your Decisions2018Book (Other academic)
    Abstract [en]

    There are basically two categories of books on decision-making. One tells stories of how intuition guides decision-making. The other delineates a formal approach, based on decision-trees or matrices, often impenetrable to real-life decision makers. This book combines the best elements of both perspectives in a way that can be easily understood by all who are struggling with complex decisions, either as individuals or as organisations. It demonstrates how intuition and psychological insights can be harnessed to design relevant models and decision strategies, and describes how goals can be adequately formed and operationalised. Finally, the book integrates these processes in an analytical framework for decision-making.

    Parallellpublicering av konferensartiklar: principer, tillämpningar och tillgänglighet i svenska publiceringsdatabaser2012Report (Other academic)
    Abstract [sv]

    Projektets huvudsyfte har varit att undersöka kvalitetsgranskade konferensartiklars tillgänglighet samt konferensers OA- och publiceringspolicies för att på så sätt klarlägga olika aspekter vad det gäller parallellpublicering i svenska publiceringsdatabaser. För ändamålet har projektdeltagarna undersökt ett urval konferenser och konferensartiklar via sina publiceringsdatabaser under ett specifikt tidsintervall och beskrivit dem utifrån ett gemensamt schema.

    Undersökningen har visat att publiceringsdatabaserna fyller en viktig funktion för att synliggöra konferenspublikationer. Vi har funnit att minst ca. 50 % av konferensartiklarna kan publiceras som post-prints i våra publiceringsdatabaser. Därför är det av stor vikt att fortsätta arbetet med att utnyttja de lokala publiceringsdatabaserna som publiceringskanal och att inte bara använda dem som ett verktyg för parallellpublicering och primärpublicerat material, som avhandlingar och rapporter, utan även som en källa framförallt för konferensartiklar ”utan hem”, som vi nu vet utgör en stor del av vårt undersökningsmaterial (ca. 15 %).

     Mellan 20-25 % av de undersökta artiklarna fanns i något slags öppet OA-arkiv; ca. hälften av dessa fanns i någon av projektdeltagarnas egen publiceringsdatabas. Detta talar för att den egna publiceringsdatabasen är en viktig faktor för öppen tillgänglighet.

    Ca. 10% av konferenserna i studien hade en uttrycklig OA-policy eller gav uttryck för en sådan genom att öppet tillgängliggöra konferensartiklar på sina konferenssajter. Ett stort problem när det gäller parallellpublicering av konferensartiklar är just bristen på information om OA-policy.

    Konferenspubliceringslandskapet är komplicerat och parallellpubliceringen av dokument härifrån är mycket tidskrävande. Vi skulle framför allt önska en liknande policy-resurs som SHERPA/RoMEO för konferenser. Men för närvarande finns inget annat alternativ än att lusläsa konferensernas upphovsrättsinformation till författarna och av denna försöka dra slutsatser om ev. parallellpublicering.

    För att underlätta framtida hantering och klassificering av konferensartiklar i svenska publiceringsdatabaser, framför allt med tanke på ev. framtida nationella bibliometriska analyser via SwePub, föreslås ett antal rekommendationer.

    Empowering rural women in Kenya with literacy skills using web 2.0: experiences of language & communication barriers in learning2010In: ICIA 2010 Proceedings, 2010, p. 100-110Conference paper (Refereed)
    Abstract [en]

    Abstract. The purpose of this paper is to illuminate ways in which language and communication relatedbarriers may be experienced in learning. Because of increased ICT usage, Project Africa’s Women’sAcademy, that is in focus of the research, felt that some issues regarding language and communicationappeared in another way than before without using ICT. The research was conducted in Lunga-Lunga,Kenya, November 2009 and through Internet communication (e.g. logs, letters stored in a socialnetworking site). The paper mainly draws on literature on ICT and Joseph Kaipayil’s ontology to collectindividual ‘experiences’. The results show that many barriers arise because of cultural diversities amongthe learners; e.g. difference ways of employing concepts and regard the objects in the world. In makingpolicies, therefore, account must be taken on a local and individual level as well as on a transnationaland collective level.

    Exploring manual and automatic query formulation in patent IR: Initial query construction and query generation process2013In: Journal of Documentation, ISSN 0022-0418, E-ISSN 1758-7379, Vol. 69, no 6, p. 873-898Article in journal (Refereed)
    Abstract [en]

    Purpose – This study aims to examine manually formulated queries and automatic query generation in an early phase of a patent “prior art” search.

    Design/methodology/approach – The study was performed partly within a patent domain setting, involving three professional patent examiners, and partly in the context of the CLEF 2009 Intellectual Property (CLEF-IP) track. For the exploratory study of user-based query formulation, three patent examiners performed the same three simulated real-life patent tasks. For the automatic query generation, a simple term-weighting algorithm based on the RATF formula was used. The manually and automatically created queries were compared to analyse what kinds of keywords and from which parts of the patent documents were selected.

    Findings – For user-formulated queries, it was found that patent documents were read in a specific order of importance and that the time varied. Annotations and collaboration were made while reading and selecting/ranking terms. Ranking terms was experienced to be harder than selecting terms. For the automatic formulated queries, it was found that the term frequencies used in the RATF alone will not quite approximate what terms will be judged as relevant query terms by the users. Simultaneously, the results suggest that developing a query generation tool for generating initial queries based on patent documents is feasible.

    Research limitations/implications – These preliminary but informative results need to be viewed in the light that only three patent experts were observed and that a small set of topics was used.

    Originality/value – It is usually difficult to get access to the setting of the patent domain and the results of the study show that the methodology provided a feasible way to study manual and the manual query formulation of the patent engineer.

    Embodiment and Gameplay: Situating the User in Crowdsourced Information Production2018In: Innovative Perspectives on Public Administration in the Digital Age / [ed] Aroon P. Manoharan, James McQuiston, IGI Global, 2018, p. 239-255Chapter in book (Other academic)
    Abstract [en]

    Distributed decision making with several stakeholders has various facets. On one hand, it enables significant opportunities for fast and efficient information provision, in particular when various structuring frameworks are provided. On the other hand, there are several problems regarding the reliability and consistency of the data produced in social media contexts as well as with the frameworks themselves. Online collaborative data production systems where crowd feedbacks are aggregated and mediated are easily affected by group biases. There are also several credibility and verification issues as the representativeness of the participants normally is difficult or impossible to determine. This chapter discusses the handling of user data in tools for crowd sourced data production and suggests a framework for describing the socio-technical setting for the production of data, and thereby the detectability of bias patterns in collaborative information production.

    Vägval: kortast, snabbasteller hälsosammast: En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.

    The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.

    The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.

    The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes. For this purpose thetest model could be applied with no or little additional development, while with furtherdevelopment it might be possible to develope a cycle route planner for public use.

    Abstract [en]

    The thesis component of a degree program is vital since the quality of it contributes to the quality of the whole degree. Maintaining the quality of the degree programs and handling the constantly increasing numbers of students entering higher education simultaneously is a challenge for many higher educational institutions. This paper presents a study of how ICT can be used to improve the quality and effectiveness of the thesis projects at Bachelors and Masters Levels. Further, how the blended model of supervision supports solving the issues of managing supervisor time efficiently and providing a quality guidance for thesis students are also explored. Supervisors’ perceptions of the ICT enabled thesis process are captured via interviews. Statistics about the completed theses and the user log data of the ICT system are triangulated to complement supervisor perceptions. Results revealed that the supervisors take advantage of the functions in the system to support improving the quality and the quantity of the theses, and the blended supervision model adapted in the thesis process support the supervisors to have a better collaboration with the students.

    Are Energy Security Concerns Dominating Environmental Concerns?: Evidence from Stakeholder Participation Processes on Energy Transition in Jordan2018In: Climate, ISSN 2053-7565, E-ISSN 2225-1154, Vol. 6, no 4, article id 88Article in journal (Refereed)
    Abstract [en]

    To satisfy Jordan’s growing demand for electricity and to diversify its energy mix, the Jordanian government is considering a number of electricity-generation technologies that would allow for locally available resources to be used alongside imported energy. Energy policy in Jordan aims to address both climate change mitigation and energy security by increasing the share of low-carbon technologies and domestically available resources in the Jordanian electricity mix. Existing technological alternatives include the scaling up of renewable energy sources, such as solar and wind; the deployment of nuclear energy; and shale oil exploration. However, the views, perceptions, and opinions regarding these technologies—their benefits, risks, and costs—vary significantly among different social groups both inside and outside the country. Considering the large-scale policy intervention that would be needed to deploy these technologies, a compromise solution must be reached. This paper is based on the results of a four-year research project that included extensive stakeholder processes in Jordan, involving several social groups and the application of various methods of participatory governance research, such as multi-criteria decision-making. The results show the variety of opinions expressed and provide insights into each type of electricity-generation technology and its relevance for each stakeholder group. There is a strong prevalence of economic rationality in the results, given that electricity-system costs are prioritized by almost all stakeholder groups.

    Prosocial behavior in an online game community: an ethnographic study2017In: Proceedings of the 12th International Conference on the Foundations of Digital Games, Association for Computing Machinery (ACM), 2017, article id 15Conference paper (Refereed)
    Abstract [en]

    We report an ethnographic study of prosocial behavior inconnection to League of Legends, one of the most popular games in the world. In this game community, the game developer, Riot Games, implemented a system that allowed players to volunteer their time to identify unacceptable player behaviors and punish players associated with these behaviors. With the prosocial goal of improving the community and promoting sportsmanship with in the competitive culture, a small portion of players worked diligently in the system with little reward. In this paper, we use interviews and analysis of forum discussions to examine how players themselves explain their participation in the system situated in the game culture of League of Legends. We show a myriad of social and technical factors that facilitated or hindered players' prosocial behavior. We discuss how our findings might provide generalizable insights for player engagement and community-building in online games.

    Managing reverse knowledge flow in multinational corporations2013In: Journal of Knowledge Management, ISSN 1367-3270, E-ISSN 1758-7484, Vol. 17, no 5, p. 695-708Article in journal (Refereed)
    Abstract [en]

    Purpose – This study aims to provide insight to the little-researched phenomenon of reverse knowledge flow within multinational corporations (MNCs) and to explain the role of managerial attention in exploiting the prospect of knowledge transfer from subsidiaries located in developing countries. Design/methodology/approach – Existing literature across disciplines has been integrated to provide a clear description of the concept of reverse knowledge flow and managerial attention, in order to explain the role of managerial attention in reverse knowledge transfer activities within MNCs. Two pilot studies were conducted on European MNCs to build the background for this study. Findings – Managerial attention is a key factor in recognising potential source of knowledge within the multinational network, and a prior requirement for knowledge transfer to take place. Attention decisions are partially based on the knowledge source location, awareness/attractiveness, and the strategic importance. Thus, MNCs can adopt managerial practices and control mechanisms to influence the attention of executives and achieve higher knowledge flow from subsidiaries. Research limitations/implications – There is a need to undertake empirical research and in-depth case studies of knowledge management practices using the arguments and framework provided in this article. Practical implications – MNCs can develop mechanisms for overcoming attention biases influence on reverse knowledge flow. The attention based approach can lead to better subsidiary integration and knowledge management practices in MNCs. Originality/value – This study advances the theory on reverse knowledge flow in MNCs by presenting an attention based theoretical framework for effective knowledge transfer.

    Global perspectives on teaching excellence – A new era for higher education2018In: Högre Utbildning, ISSN 2000-7558, E-ISSN 2000-7558, Vol. 8, no 1, p. 42-43Article, book review (Other academic)
    Abstract [en]

    Are you searching for a book that discusses teaching excellence from both a global and future perspective? In that case, Global perspectives on teaching excellence - A new era for higher education is a highly relevant and interesting book with contributions from 42 individuals, all involved in higher education in many countries. Christine Broughan, Graham Steventon and Lynn Clouder, researchers from Coventry University in the United Kingdom, are the editors. In this book, the concept of teaching excellence is explored by international authors who highlight a number of key issues. One issue is that teaching excellence has no international definition because it is such a complex subject covering diverse ontological, epistemological and cultural contexts. We can read this book with three questions in mind: If and how teaching excellence can be measured; what impact frameworks, initiatives and awards have on teaching excellence; and, what are the new challenges for global teaching excellence in the 21st century? The authors’ focus is a blend of political, theoretical and applied research which gives the reader many different perspectives on teaching excellence.

    Migrant teachers’ experiences with the use of digital technology and media during their placement period in Swedish schools2018In: Proceedings of the ATEE Winter Conference 2018: Technology and Innovative Learning / [ed] Michiel Heijnen, Miranda de Hei, Stan van Ginkel, ATEE - Association for Teacher Education in Europe, 2018, p. 64-72Conference paper (Refereed)
    Abstract [en]

    Professional development directed towards migrant teachers is provided at six Swedish Universities. These teachers study 1-2 years to become eligible to teach in Swedish schools. Part of this training is the placement period, where they become familiar with the Swedish school environment while guided by a placement supervisor. In this study, we examine migrant teachers’ experiences with digital technology and media during their placement period, using the theoretical concept of “unfamiliar ways of thinking and practising”. Data in this qualitative study was collected from a total of 34 migrant teachers through five focus groups and nine individual interviews. The migrant teachers’ former teacher education was completed in twenty different countries. A qualitative content analysis was conducted. The results indicate that the placement supervisor is of great importance for the improvement of migrant teachers’ digital competence, as it is defined in the Swedish context. As a role model, the placement supervisor can be a motivator and an inspirational force for migrant teachers. Findings also show that migrant teachers express unfamiliar ways of thinking and practising concerning the curricula, pedagogical methods and in their role as teachers, which has implications for how digital technology and media isused pedagogically.

    Unfamiliar ways of thinking and practising in teacher education - Experiences by migrant teachers2018In: Changing perspectives and approaches in contemporary teaching: Conference proceedings / [ed] Marija Sablić, Alma Škugor, Ivana Đurđević Babić, ATEE - Association for Teacher Education in Europe, 2018, p. 219-235Conference paper (Refereed)
    Abstract [en]

    In Sweden, a growing number of students in teacher education have a migrant background. A specific group consists of those with a foreign teaching degree who wish to complement their studies to become eligible to teach in Swedish schools. Within Swedish teacher education, there is a lack of studies examining how migrant teachers perceive the Swedish educational system, how teaching and learning are understood and practised, and how these experiences can be related to migrant teachers’ previous experiences. In the present study, migrant teachers’ encounters with Swedish teacher education at four Swedish Universities were examined in relation to the notions of “unfamiliar ways of thinking and practising” to highlight ways of teaching and learning that are perceived as unfamiliar. Data in this study was drawn from a web survey completed by 228 respondents with a foreign teaching degree coming from 54 countries. Additionally, five focus groups and nine individual interviews were conducted. Furthermore, 30 reflective texts written by 15 participants were analysed. The results highlight the cultural embeddedness of Swedish teacher education and demonstrate how migrant students struggle with unfamiliar teaching and learning methods, epistemological understanding, examination practices and the roles and expectations from society or between teachers and students. To conclude, this research underscores the importance of situated reflexivity and awareness with intercultural experiences in mind, when designing teaching and learning, and supporting inclusion and equality. These findings and the way of identifying the unfamiliarity in teaching and practising may be applicable in other countries as well.

    A Monte Carlo track structure simulation code for the full-slowing-down carbon projectiles of energies 1 keV u-1–10 MeV u-1 in water2013In: Physics in Medicine and Biology, ISSN 0031-9155, E-ISSN 1361-6560, Vol. 58, no 3, p. 673-702Article in journal (Refereed)
    Abstract [en]

    The paper presents a new Monte Carlo track structure code (KURBUC_carbon) for simulations of full slowing down carbon projectiles C0–C6+ of energies 1 keV/u–10 MeV/u in water vapour. The code facilitates investigation of spatial resolution effect for scoring track parameters under the Bragg peak of carbon ion beam. Interactions of carbon projectiles and secondary electrons were followed event-by-event down to 1 keV/u cutoff for primary ions, and down to 10 eV for electrons. Electronic interactions and nuclear elastic scattering were taken into account, including charge exchange reactions and double electronic interactions for the carbon projectiles. The reliability of the code was tested for radial dose, range, and W-value. The calculated results were compared with the published experimental data, and other model calculations. The results obtained showed good agreement in most cases where comparisons could be made. Depth dose profiles for 1-10 MeV/u C6+ were used to form an SOBP of 0.35 mm width in water. At all depths of the SOBP, the energy distributions of the carbon projectiles varied appreciably with the change in the scoring volume. The corresponding variation was nearly negligible for the track average LET, except at the distal end of the SOBP. By varying the scoring slab thickness from 1 to 100 µm, the maximum track average LET decreased by ~30%. The Monte Carlo track structure simulation in the full slowing down mode is a powerful tool for investigation of biophysical properties of radiation tracks under the Bragg peak and SOBP of carbon ion beam. For estimation of radiation effectiveness under the Bragg peak the new Monte Carlo track structure code provides yet another accurate and effective dosimetry tool at a single cell level. This is because radiobiology within tissue elements can only be understood with dosimetry at cellular and subcellular level.

    Investment Appraisal in the Public Sector – Incorporating Flexibility and Environmental Impact2017In: Journal of Advanced Mangement Science, ISSN 2168-0787, Vol. 5, no 3, p. 182-189Article in journal (Refereed)
    Abstract [en]

    Real asset investment appraisal in the public sector often requires that objectives beyond return on investment are taken into account. Recently, environmental impact and climate change issues are often used to motivate investments, but despite this formal approaches are seldom being used for this purpose. In this paper we investigate the application of real option valuation and multi-criteria decision analysis in the appraisal of a public sector investment in the form of a logistics park, aimed to reduce the emissions from cargo traffic. Although this appraisal approach captures important features of the real situation in terms of that flexibility is considered and multiple criteria is taken into account, the requirement for the information needed for the model led to a need to use best-estimates, and a systematic approach to sensitivity analysis is therefore desired.

    An m-Government Solution for Complaint and Problem Management: Designing a Solution for Government 2.02014Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In recent years emphasis has been placed on opening up governments and empowering and engaging citizens in governmental activities: this view of e-government is referred to as government 2.0. Government 2.0 focuses on governments becoming more transparent, accessible, and responsive, and on governments promoting increased collaboration and participation.  There is also an increasing demand from citizens to interact and gain access to government services through mobile devices. Adopting mobile and wireless technology within the public sector is referred to as mobile government (m-government) and this new phenomenon is expected to become an important part of the development of e-government. By combining government 2.0 and m-government, The Organisation for Economic Co-operation and Development (OECD) and the research community envisages benefits and calls for action within this field.

    This research answers this call, and addresses the research problem of how to design an m-government solution for complaint and problem management that enables government 2.0. Challenges that inhibit Swedish municipalities from adopting and utilizing such a solution are also identified in this research.

    Citizens in Sweden can submit complaints and problems concerning a community, such as broken streetlights, to municipalities. By enabling complaints and problems to be reported through mobile devices it facilitates reporting at the point and time of discovery of the issue. Complaint and problem reporting is therefore a suitable m-government service. The m-government solution for complaint and problem management was designed and evaluated within a research project. This compilation thesis builds on and communicates research performed within the research project. By following a design science research methodology, the complaint and problem management solution is designed and evaluated. The solution (Munizapp) comprises a mobile application (app) and an integration platform (ePlatform). The app is the front-end that enables citizens to report complaints and problems to municipalities. The ePlatform facilitates seamless two-way communication between the app and back-end case management system in municipalities. A theoretical evaluation shows that the solution has functionalities that enable all aspects of government 2.0. Additional evaluations indicate evidence of citizens finding the solution valuable and easy to use. There is willingness among municipalities to adopt and utilize the designed m-government solution, but there are challenges that inhibit them from realizing the full potential of the solution. The challenges identified in this research are described and related to business process management and to government 2.0. Future research should investigate how to overcome these challenges.

    Predicting Structural and Functional Properties of Membrane Proteins from Protein Sequence2011In: Annual Reports in Computational Chemistry / [ed] Wheeler, R.A., Amsterdam: Elsevier Science BV , 2011, p. 39-64Chapter in book (Refereed)
    Abstract [en]

    Integral transmembrane (TM) proteins are essential constituents of biological membranes where they fulfill a variety of important cellular functions. Because of difficulties with determining their structures by experimental techniques, comparably few 3D structures of membrane proteins are known so far. Therefore, computational methods trained on the available structures using only the protein sequence as input have become important tools in this field. In this chapter, we give a short introduction to the topic and then summarize recent bioinformatics tools for the prediction of structural as well as functional properties of alpha-helical and beta-barrel TM proteins. We present methods that allow predicting the locations of alpha-helical and beta-strand TM segments, to determine the exposure status of residues in the TM region to the surrounding lipids, and that allow functional annotations from the protein sequence.

    Digital Games and Simulations for Learning2018In: Games and Education: Designs in and for Learning / [ed] Hans Christian Arnseth, Thorkild Hanghøj, Thomas Duus Henriksen, Morten Misfeldt, Robert Ramberg, Staffan Selander, Brill Academic Publishers, 2018, p. 17-27Chapter in book (Refereed)
    Abstract [en]

    Digital games and simulations for learning are not new phenomena. However, with the advancements in technology, they have gathered increasing interest over recent years. With digital ubiquity, games and simulations offer a compelling case for use in schools. As such, it is useful to understand the value and issues related to the use of digital games and simulations for learning as well as to develop a new frame for thinking on how to design learning in educational settings, harnessing the affordances of technology through the effective use of digital games and simulations.

    Bouncing Back: Assessing the Resilience of Infrastructure Projects and the Use of Average Outage Factors2017In: Proceedings of the 21st Annual International Real Options Conference, Boston, MA: Real Options Group , 2017Conference paper (Refereed)
    Abstract [en]

    Motivated by the need to bolster the resilience of infrastructure, such as bridges, nuclear power plants, and ports, in face of extreme weather events, we consider two types of projects: “riskier” and “safer.” Each type of project, once constructed, earns identical instantaneous cash flows and is subject to the same risk of outage, which causes its cash flows to diminish. The only difference between the two projects is that the repair rate of the “safer” project is greater than that of the “riskier” one. Naturally, the “safer” project is more valuable to an investor due to its greater resilience. However, how much extra would an investor be willing to pay for this resilience? Under which circumstances would it be reasonable to replace the outage and repair rates with average outage factors? Using a real options approach, we show that even though the proportions of up- and down-times remain fixed, changes in the transition rates affect the willingness to pay for resilience. This implies that use of average outage factors will incorrectly inflate the resilience premium. In fact, only in the limit when transitions occur at infinitely high rates does the use of average outage factors accurately reflect the investor’s willingness to pay for resilience. Somewhat paradoxically, very frequent transitions reflect a situation in which average outage factors may be used.

    A simulation-game to explore collective critical infrastructure resilience2018In: 28th European Safety and Reliability Conference, Taylor & Francis Group , 2018Conference paper (Refereed)
    Abstract [en]

    Resilience of interdependent infrastructures increasingly depends on collaborative responses from actors with diverse backgrounds that may not be familiar with cascade effects into areas beyond their own sector. A simulation-game can enable societal actors to obtain a deeper understanding of the interdependencies between their infrastructures and their respective crisis responses. Following a design science approach, a simulation-game has been developed that combines role-playing simulation and computer simulation. The simulation-game challenges participants to address the interaction between payment disruptions, food and fuel supply, security problems (riots, robberies) and communication challenges (preventing hoarding). A number of crucial design choices were handled while developing the simulation-game. The main design challenges were: How to validate an unthinkable escalation scenario?; How to give the simulation a sufficient level of detail on all aspects and keep the complexity graspable so it can be played instantly?; and How much time should each playing round take?
