    Role and Challenges of Data-Driven Design in the Product Innovation Process2018Inngår i: Proceedings of the 16th IFAC Symposium on Information Control Problems in Manufacturing - INCOM 18, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The paper discusses the role and the challenges of integrating Data-Driven Design (DDD) models in the product innovation process. Firstly, based on academic literature on the Product Innovation Value Streamsand on Model-Based Decision Supports, the paper highlights how and when the use of DDD models can support a more effective product innovation process. Secondly, it highlights a list of challenges to be considered for the development of new DDD models for decision support. Ultimately, those challenges are formalized in an evaluation matrix intended to guide the further development of DDD.

    School Choice, School Performance and School Segregation: Institutions and Design2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This thesis consists of four self-contained chapters. 

    The first chapter, Are Parents Uninformed? – The Impact of School Performance Information on School Choice Behavior and Student Assignment, is co-authored by Elsisabet Olme. We investigate the effects of school performance information on school choice behavior and student assignment. A randomly selected group of students, about to choose middle school, were provided with information about the performance of the available schools. Households that received the information became more prone to choose a top-performing school. This effect is driven by native and high-skilled households. We simulate how this change in choice behavior translates into changes in school assignment. We find that enrollment in the top-performing schools increases but the effect is muted by limited capacity. We also find that the treatment increases the gap in school performance between advantaged and disadvantaged households, decreases segregation in terms of migration background and increases segregation in terms of parental skill-level. 

    The second chapter, School Choice Priority Structures and School Segregation, is also co-authored by Elsisabet Olme. We evaluate how school segregation is affected by altering the priority structures in a school choice program. We evaluate three priority structures, one proximity-based, one lottery-based and one based on soft quotas. Using actual choice data and simulations we find that that priority structures do affect school segregation. When reserving seats for different groups, schools are less segregated compared to when using systems where priorities are based on proximity or a lottery. We find that the average costs in terms of welfare are limited but that the different priority structures benefit different subgroups. 

    In the third chapter, Debiasing the Gender Differences in Willingness to Compete – The Effects of General Information on the Gender Gap and Efficiency, I explore if informing people about the gender differences in the willingness to compete and the accompanying inefficiencies can reduce said differences and inefficiencies. In an experiment where the participants got to choose whether to compete or not, a random sample of participants were informed about the gender differences in willingness to compete and the related inefficiencies. Among those not informed, men were much more likely to compete than women. There were also significant inefficiencies from low-performing men choosing to compete and high-performing women choosing not to. The treatment reversed the gender gap and significantly reduced inefficiency. 

    The fourth chapter, The Housing Wealth Effect: Quasi-Experimental Evidence is co-authored by Roine Vestman and Björn Tyrefors Hinnerich. We exploit a quasi-experiment that occurred in Stockholm in 2007 when the contract of Stockholm's city airport was unexpectedly renewed. We estimate an immediate shock of approximately 16 percent to house prices close to the airport. This source of price variation is ideal to identify housing wealth effects since it is local and unrelated to variation in macroeconomic conditions. Using a household data set with granular geographic information on primary residence, we find an MPC on cars of less than 0.2 cents per dollar.

    Low-temperature based thermal micro-grids: operation and performance assessments2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. This dissertation seeks to introduce, discuss, and assess from a techno-economic perspective the concept of low-temperature (LT) based thermal micro-grids (subnets) as active distribution thermal networks. It explores the role of the subnet at the system distribution level supervised by an active agent (DH substation), performing tasks of heat supply and demand management (storage and dispatch), as well as coordinating bidirectional flows.

     

    Here, a mixed methodological approach based on analytical simulation for the assessment of alternatives to evaluate a set of technologies is developed and discussed. This approach covers: the identification of knowledge gaps through the state-of-the-art analysis; a collection of incremental technical and/or economic performance assessments; and the analysis of a measurement data set from an existing LTDH demonstration project.

     

    Key findings of this work include: an updated and improved model of aggregated heat loads; identification of differences in load and temperature patterns for certain LT subnets; analysis of benefits and drawbacks of active substations with distributed heat sources and/or storage; and the impact on the reduction of the primary network return temperature as a consequence of the increase in the share of LT subnets, leading to lower generation and operating costs.

     

    These outcomes reveal that the integrated design and operation of the active thermal micro-grid have the potential to improve both the performance of the subnet, and that of the primary network. It further enhances the capability of the overall system to integrate unconventional and distributed heat sources together with energy efficient buildings by increasing the system’s flexibility and controllability. Active thermal distribution networks will likely become a subsequent step in the technological development of DH technologies, to address the matter of providing comfort heating in an effective and cost-efficient manner. This work advances the current DH knowledge by identifying synergies and challenges that arise with these new developments, in order for DH technology to play a key role in the future smart and sustainable energy system.

    A Multimodal Corpus for Mutual Gaze and Joint Attention in Multiparty Situated Interaction2018Inngår i: Proceedings of the Eleventh International Conference on Language Resources and Evaluation (LREC 2018), Paris, 2018, s. 119-127Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we present a corpus of multiparty situated interaction where participants collaborated on moving virtual objects on a large touch screen. A moderator facilitated the discussion and directed the interaction. The corpus contains recordings of a variety of multimodal data, in that we captured speech, eye gaze and gesture data using a multisensory setup (wearable eye trackers, motion capture and audio/video). Furthermore, in the description of the multimodal corpus, we investigate four different types of social gaze: referential gaze, joint attention, mutual gaze and gaze aversion by both perspectives of a speaker and a listener. We annotated the groups’ object references during object manipulation tasks and analysed the group’s proportional referential eye-gaze with regards to the referent object. When investigating the distributions of gaze during and before referring expressions we could corroborate the differences in time between speakers’ and listeners’ eye gaze found in earlier studies. This corpus is of particular interest to researchers who are interested in social eye-gaze patterns in turn-taking and referring language in situated multi-party interaction.

    FARMI: A Framework for Recording Multi-Modal Interactions2018Inngår i: Proceedings of the Eleventh International Conference on Language Resources and Evaluation (LREC 2018), Paris: European Language Resources Association, 2018, s. 3969-3974Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we present (1) a processing architecture used to collect multi-modal sensor data, both for corpora collection and real-time processing, (2) an open-source implementation thereof and (3) a use-case where we deploy the architecture in a multi-party deception game, featuring six human players and one robot. The architecture is agnostic to the choice of hardware (e.g. microphones, cameras, etc.) and programming languages, although our implementation is mostly written in Python. In our use-case, different methods of capturing verbal and non-verbal cues from the participants were used. These were processed in real-time and used to inform the robot about the participants’ deceptive behaviour. The framework is of particular interest for researchers who are interested in the collection of multi-party, richly recorded corpora and the design of conversational systems. Moreover for researchers who are interested in human-robot interaction the available modules offer the possibility to easily create both autonomous and wizard-of-Oz interactions.

    Crowdsourced Multimodal Corpora Collection Tool2018Inngår i: Proceedings of the Eleventh International Conference on Language Resources and Evaluation (LREC 2018), Paris, 2018, s. 728-734Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In recent years, more and more multimodal corpora have been created. To our knowledge there is no publicly available tool which allows for acquiring controlled multimodal data of people in a rapid and scalable fashion. We therefore are proposing (1) a novel tool which will enable researchers to rapidly gather large amounts of multimodal data spanning a wide demographic range, and (2) an example of how we used this tool for corpus collection of our "Attentive listener'' multimodal corpus. The code is released under an Apache License 2.0 and available as an open-source repository, which can be found at https://github.com/kth-social-robotics/multimodal-crowdsourcing-tool. This tool will allow researchers to set-up their own multimodal data collection system quickly and create their own multimodal corpora. Finally, this paper provides a discussion about the advantages and disadvantages with a crowd-sourced data collection tool, especially in comparison to a lab recorded corpora.

    Under the teacher´s radar: Literacy practices in task-related smartphone use in the connected classroom2018Inngår i: L1-Educational Studies in Language and Literature, ISSN 1567-6617, E-ISSN 1573-1731, Vol. 18, s. 1-26Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In this article, we explore the role of smartphones in the classroom and how they interact with teaching. Drawing on examples of literacy events, we show how the students use the smartphone as a resource to exercise power and influence in the literacy practices in which they participate in the classroom, in relation to a teaching content. These actions take place without the teachers being aware of them, and thus theseprocesses dismantle the teacher’s authority in terms of access to, and overview of, the diversity of texts that are managed by the students in the classroom. The article concludes that it is evident that digital tools in general, and smartphones in particular, change the role of the teacher and the school, and thatthe students’ design of texts places new or altered demands on students as well as teachers.

    Influence of microwave activation on the catalytic behavior of Pd-Au/C catalysts employed in the hydrodechlorination of tetrachloromethane2018Inngår i: Reaction Kinetics, Mechanisms and Catalysis, ISSN 1878-5190, E-ISSN 1878-5204, Vol. 124, nr 1, s. 375-388Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This work investigates the influence of activation by microwave irradiation on the catalytic properties of Pd-Au/C-Sibunit catalysts in the hydrodechlorination of CCl4. Pd and Pd-Au samples were thoroughly characterized by CO chemisorption, X-ray diffraction, TPHD and STEM, and used in gas phase hydrodechlorination of tetrachloromethane. The studies showed that homogenous Pd-Au alloys are formed more efficiently if short-time microwave activation is applied instead of conventional activation by H-2 reduction at 380 A degrees C. These catalysts show higher activity, stability and higher selectivity towards the desired products (C1-C5 hydrocarbons) than the catalysts activated by conventional reduction in 10%H-2/Ar flow.

    Predictors of adverse outcome in patients with myocardial infarction with non-obstructive coronary artery (MINOCA) disease2018Inngår i: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 261, s. 18-23Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCAs) is an increasingly recognized entity. No previous study has evaluated predictors for new major adverse cardiacvascular events (MACEs) and death in patients with MINOCA.

    Methods: We conducted an observational study of MINOCA patients recorded between July 2003 and June 2013 and followed until December 2013 for outcome events. Out of 199,163 MI admissions, 9092 consecutive unique patients with MINOCA were identified. The mean age was 65.5 years and 62% were women. MACE was defined as all-cause mortality, rehospitalization for acute MI, ischemic stroke and heart failure. Hazard ratio and 95% confidence interval (HR; 95% CI) was calculated using Cox-regression.

    Results: A total of 2147 patients (24%) experienced a new MACE and 1254 patients (14%) died during the mean follow-up of 4.5 years. Independent predictors for MACE after adjustment, were older age (1.05; 1.04–1.06), diabetes (1.44; 1.21–1.70), hypertension (1.25; 1.09–1.43), current smoking (1.38; 1.15–1.66), previous myocardial infarction (1.38; 1.04–2.82), previous stroke (1.69; 1.35–2.11), peripheral vascular disease (1.55; 1.97–2.23), chronic obstructive pulmonary disease (1.63; 1.32–2.00), reduced left ventricular ejection fraction (2.00; 1.54–2.60), lower level of total cholesterol (0.88; 0.83–0.94) and higher level of creatinine (1.01; 1.00–1.03). Independent predictors for all cause death were age, current smoking, diabetes, cancer, chronic obstructive pulmonary disease, previous stroke, reduced left ventricular fraction, lower level of total cholesterol and higher levels of creatinine and CRP.

    Conclusions: The clinical factors predicting new MACE and death of MINOCA patients seem to be strikingly similar to factors previously shown to predict new cardiovascular events in patients with MI and obstructive coronary artery disease.

    Incremental prognostic value of coronary and systemic atherosclerosis after myocardial infarction2018Inngår i: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 261, s. 6-11Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The role of systemic atherosclerosis in myocardial infarction (MI) patients is not fully understood. We investigated the incremental prognostic value of coronary and systemic atherosclerosis after acute MI by estimating extra-cardiac artery disease (ECAD) and extent of coronary atherosclerosis.

    Methods and results: The study included 544 prospective MI patients undergoing coronary angiography. For all patients, the longitudinal coronary atherosclerotic extent, expressed as Sullivan extent score (SES) was calculated. In addition, the patients underwent non-invasive screening for ECAD in the carotid, aortic, renal and lower limb. SES was found to be associated with ECAD independent of baseline clinical parameters [adjusted odds ratio (OR) 1.04 95% confidence interval (CI) 1.02–1.06, P < 0.001]. Extensive systemic atherosclerosis, defined as the combination of extensive coronary disease (SES ≥ 17) and ECAD, was associated with higher risk for all-cause mortality compared to limited systemic atherosclerosis (SES < 17 and no ECAD) (hazard ratio [HR] 2.9 95% CI 1.9–4.5, P < 0.001, adjusted for Global Registry of Acute Coronary Events risk score parameters 1.8, 95% CI 1.1–3.0, P = 0.019). The risk for the composite endpoint of cardiovascular death or hospitalization was significantly higher in patients with extensive systemic atherosclerosis compared to patients with limited systemic atherosclerosis (HR 3.1, 95% CI 2.1–4.7, P < 0.001, adjusted HR 1.9, 95% CI 1.2–3.1, P < 0.004).

    Conclusions: Visual estimation of the longitudinal coronary atherosclerotic extent at the time of MI predicts ECAD. Coexistence of extensive coronary disease and ECAD defines a group with particularly poor prognosis after MI.

    Celebrating Red October: A Story of the Ten Anniversaries of the Russian Revolution, 1927-20172018Inngår i: Scando-Slavica, ISSN 0080-6765, E-ISSN 1600-082X, Vol. 64, nr 1, s. 7-30Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This essay seeks to shed light on how the constantly evolving Soviet system shaped and reshaped the myth of Red October and how post-Soviet ruling elites treated the memory surrounding the 1917 Russian Revolution while pursuing political ends. At the center of the analysis are the politics of history and commemorative practices of the past ten decades, with the demise of communist ideology and the breakup of the Soviet Union serving as clear rupture points. Through its focus on revolutionary jubilees, the essay traces the trajectory of attitudes towards the Revolution over the past one hundred years - from treating Red October as a foundation myth for the entire Soviet era to viewing it as an inconvenient event that does not fit easily into the essentially counter-revolutionary official narrative of contemporary Russia.

    Definitions of climatological and discharge days: do they matter in hydrological modelling?2018Inngår i: Hydrological Sciences Journal, ISSN 0262-6667, E-ISSN 2150-3435, Vol. 63, nr 5, s. 836-844Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The performance of hydrological models is affected by uncertainty related to observed climatological and discharge data. Although the latter has been widely investigated, the effects on hydrological models from different starting times of the day have received little interest. In this study, observational data from one tropical basin were used to investigate the effects on a typical bucket-type hydrological model, the HBV, when the definitions of the climatological and discharge days are changed. An optimization procedure based on a genetic algorithm was used to assess the effects on model performance. Nash-Sutcliffe efficiencies varied considerably between day definitions, with the largest dependence on the climatological-day definition. The variation was likely caused by how storm water was assigned to one or two daily rainfall values depending on the definition of the climatological day. Hydrological models are unlikely to predict high flows accurately if rainfall intensities are reduced because of the day definition.

    Adopting Information Systems Perspectives from Small Organizations2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Why do organizations adopt information systems? Is it just because of financial reasons, of concerns for efficiency? Or is it due to external pressures, such as competitor pressure, that an organization adopts an information system?

    And, how does the adoption take place? Is it a linear process, or is the process one of  conflicts? Does a specific person govern this process, or do we have multiple parties involved? What happens if these conflicts occur among those involved? How does the organization move on and achieve a successful information system adoption?

    By investigating two organizations, one international academic journal and one South American manufacturing company, this thesis aims to investigate the whys and hows of information system adoption, and aims to contribute to the discourse on information system adoptions in small organizations – an often underrepresented segment in information system adoption literature.

    By adopting different theoretical lenses throughout the five research papers included, this body of work suggests that even when seemingly simple, information system adoptions can become rather complex. The cases reveal that the role of information systems and issues related to information system adoptions are often not well thought-out in the early days of the organization. The actors’ understandings of adoption and consequences mature and the information systems become more intertwined.

    Common use of stakeholder theory introduces general stakeholders and their interaction with the focal organization. The cases reveal that the adoption process involves multiple actors, even within what would initially appear as a stakeholder, and that those actors can be in conflict with each other. These conflicts often lead to negotiations, and the cases reveal that these negotiations are opportunities of learning; the actors engage with the information system and with each other, gaining new knowledge about the issues at hand.

    The dissertation argues that there are various social worlds in information system adoptions, and various factors – ranging from organizational structure to social norms – that often affect why and how the organization undergoes an adoption process. The multiple power relations and divergent interests of stakeholders in these adoption processes, and how information systems affect other parts of the organization, reinforce the need for a well thought-out, flexible and reflexive approach to information system adoptions.

    Adopting Information Systems in a Small Company: A Longitudinal Study2016Inngår i: Journal of Applied Economics and Business Research, ISSN 1927-033X, E-ISSN 1927-033X, Vol. 6, nr 4, s. 269-283Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For some time there has been an increase in adoption of enterprise systems by small companies. With welldocumented potential benefits, there are a lot of reasons to adopt them. In this study however the choice to adopt smaller pieces of information systems by a small organization is investigated to provide a counter example to the integrated-solution literature. With the intention to adopt an enterprise system at the beginning, the case provides a dynamic story of a small organization and how various factors impacted on the intention and resulted in an assemblage of information systems instead. By adoption the technology-organisation-environment framework and a single case study design, the case indicates that in addition to the oft-cited factors such as organisational size and IT readiness, social norms and the characteristics of a central individual, such as the owner, play a prominent role in information systems adoption, and highlights how these factors are connected to each other.

    Learning by negotiation – Implementing a journal management system2015Inngår i: / [ed] Lambrinoudakis, K., Morabito, V., Themistocleous, M., 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This study investigates how an international academic journal invests in an information system. Following the criticism that learning in an organisation is not conflict free the study sketches the decision making around the information system as a series of negotiations. The case shows that during these negotiations, the information system played the role of a boundary object that resulted in the editorial team understanding the system in different ways than previously. These negotiations paved the way for learning in the organisation, with the information system highlighting differences among the participants involved with the journal.

    Talking to the students: Repertoires of a syllabus2014Inngår i: Proceedings of the Fifth International Conference Social Communication in the Real and Virtual World / [ed] Kowal, J.; Kuzio, A.; Wawrzak-Chodaczek, M., University of Wrocław, Poland; Linköping University, Sweden; College of Management "Edukacja" Wrocław, Poland , 2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    • Purpose: The aim of this paper is to identify the repertoires that the teachers draw from when writing a course syllabus.

    • Design/Methodology: To achieve this a syllabus of a course is scrutinised by using discourse analysis, namely interpretative repertoires.

    • Results: Two distinct repertoires are identified which the teacher draw from. By employing these repertoires the opposing demands from the students and regulatory bodies as well as the traditional role of the teacher, the teachers maintain their position. By using language the teachers are able to maintain the traditional roles of teacher and student, thus reinforce the existing system.

    • Limitations: The study uses only one syllabus as its data, thus limiting the potential generalizability of the findings.

    • Research/Practical Implications: Results show how the teachers use rather paradoxical repertoires to maintain their position and reinforce the existing system.

    • Originality/Value: The results show that even on a syllabus the teachers have to maintain their position when confronted with demands from students and regulatory bodies, and employ paradoxical repertoires to do so.

    Constructing an open source ERP sales pitch - In search for interpretative repertoires2014Inngår i: Proceedings of the 8th Mediterranean Conference on Information Systems, Verona, Italy, September 03-05, 2014 / [ed] Mola, L. Carugati, A. Kokkinaki, A. Pouloudi, N., 2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Open source enterprise resource planning (OS-ERP) systems have been gaining recognition in the last few years. However while the research has focused on the implementation phase of OS-ERP systems, there is scant research done on the adoption process of such systems. This paper looks at an early paper on an OS-ERP system, targeting both practitioners and researchers, to identify the repertoires used to argue for the adoption of the said system. To achieve this aim the paper is evaluated by using a strain of discourse analysis - interpretative repertoires. Three distinct repertoires are identified that are used to argue for the unique value gained by adopting the OS-ERP in question, by both highlighting positive aspects of the system, as well as alluding the pitfalls of other systems. These repertoires are also mapped to the existing literature on diffusion of innovations and resource based view to highlight how the existing ideas are reformulated in the identified repertoires.

    On Architectural Space and Modes of Subjectivity: Producing the Material Conditions for Creative-Productive Activity2018Inngår i: Urban Planning, ISSN 2183–7635, Vol. 3, nr 3, s. 70-82Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article discusses extended implications of Lefebvre’s The Production of Space in the context of contemporary global neoliberalism, by focus on its presence in architectural space as lived space and spatial practice. The main discussion concerns Lefebvre’s concepts of abstract space, in relation to Felix Guattari’s three ecologies, and the Aristotelean triad of aisthesis, poiesis and techné. The focus here concerns material architectural space and its relation to modes of subjectivity, especially creative-productive versus consuming subjectivities. The argument begins by elaborating on an understanding of abstract space as present in material architectural space as pervasive processes of disassociation of materiality and labor, and proceeds to through these concepts discuss modes of subjectivity—the dependence of abstract space on subjects as consumers—and the way this relates to challenges of sustainability. It further points to the importance of architectural space considered as built material environment for creative-productive modes of subjectivity which challenge abstract space and in extension consumer society, by offering potential dispositions that set subjects in a different relation to the world.

    The design and simulated performance of a fast Level 1 track trigger for the ATLAS High Luminosity Upgrade2017Inngår i: EPJ Web of Conferences, ISSN 2101-6275, E-ISSN 2100-014X, Vol. 150, artikkel-id 00008Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The ATLAS experiment at the High Luminosity LHC will face a fivefold increase in the number of interactions per bunch crossing relative to the ongoing Run 2. This will require a proportional improvement in rejection power at the earliest levels of the detector trigger system, while preserving good signal efficiency. One critical aspect of this improvement will be the implementation of precise track reconstruction, through which sharper trigger turn-on curves can be achieved, and b-tagging and tau-tagging techniques can in principle be implemented. The challenge of such a project comes in the development of a fast, custom electronic device integrated in the hardware based first trigger level of the experiment. This article will discuss the requirements, architecture and projected performance of the system in terms of tracking, timing and physics, based on detailed simulations. Studies are carried out using data from the strip subsystem only or both strip and pixel subsystems.

    Las políticas de invitar : Coarticulación de temas en torno a la participación pública en diseño: Politics of inviting : co-articulations of issues in designerly public engagement2017Inngår i: Diseña, ISSN 0718-8447, nr 11, s. 110-121Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The article engages with the politics of inviting by proposing a shift in what we invite to, and when. Rather than inviting stakeholders to participate in design projects before use, the article argues for the value of inviting participants to take part in co-articulations of issues that arise in the course of the ongoing living with technologies. Based on two public engagement projects, it is shown how co-articulations emerge through a combination of invitations and responses by the participants. When the issue emerges more inventively is usually when the assumptions enacted through the invitations do not t well with how participants live with technologies.

    Inclusion through participation: understanding participation in the international classification of functioning, disability, and health as a methodological research tool for investigating inclusion2018Inngår i: Frontiers in Education, ISSN 2504-284X, Vol. 3, nr 41Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper investigates the use and validity of the International Classification of Functioning disability and health (ICF) as a common language for describing inclusive educational settings. There is a specific focus on investigating participation through the ICF as one aspect of inclusion as an improved understanding of participation as a measure of inclusion will greatly benefit children with additional support needs. In addition there will be a better understanding of the operationalization of participation, in terms of both policy and practice, and improved applications of the ICF. The study uses a narrative summary to review to analyse the findings from a selection of studies where the ICF has been used as a methodological tool in the field of education. In the 16 included studies the ICF is either used to present a new theoretical position, synthesize a new research approach or tool, or is integrated into the framework of an existing research method. Findings also show that the ICF is used in a number of different ways and that when it is used directly, variation is found in the type of information that was linked to ICF codes or categories. In conclusion further clarity on defining and measuring participation with the ICF framework is required in order to create a more consistent tool for investigating inclusive education. One way to improve the construct of participation is to take a bi-dimensional approach. It is the authors’ belief that this newer approach to modelling participation will be considered in any future revisions of the ICF/ICF-CY – a so-called ‘ICF-2’. This would thus create a more accountable classification framework that succeeds in capturing the involvement experience of the individual and in doing so achieves a more effective and useful classification framework for the field of inclusive education.

    BRIDGING THE INFORMATION GAP: Supporting Evidence-Based Medicine and Shared Decision-Making through Information Systems2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Practicing evidence-based medicine (EBM) and shared decision-making (SDM)along the patient process is important in today's healthcare environment, as thesemodels of care offer a way to improve quality and safety of care, patient satisfaction,and reduce costs. EBM is the conscientious and judicious use of current best medicalevidence in conjunction with clinical expertise. It also includes taking into accountpatient values and preferences to guide decisions about the care of individual patients.SDM offers a process that guides how a healthcare professional (e.g., a physicianor a nurse) and a patient jointly can participate in a decision after incorporatingthe body of evidence (the options, benefits and harms) and considering the patient'svalues and preferences.

    The degree to which healthcare professionals can practice EBM and SDM is dependentupon the availability of information about the patient (e.g., medical diagnosis,therapies as well as laboratory and administrative information) and medical evidence(such as medical guidelines). Patient information is a prerequisite for making decisionsabout the care of individual patients and it is evidence-based medicalknowledge, clinical expertise as well as patient values and preferences that guidethese decisions. Moreover, for patients to be able to communicate values and preferencesas well as participate effectively in their own care, they need to have a basicunderstanding of their condition and treatment options, and the consequences ofeach. Hence, they need access to the same information streams—in "patientaccessible"form—as their physician(s) and care team throughout their journey (process)in healthcare. However, making the right decisions about the care of individualpatients at the right time and place is a challenge for healthcare professionals. Due tointeroperability issues, existing information systems do not support a seamless flowof patient information along the patient process. Healthcare professionals are thereforeunable to easily access up-to-date information about the patient at the right timeand place. The situation is complicated further by the fragmentation of medical evidencein different repositories and its presentation by diverse providers, each withunique ideas about how information should be organized and how search enginesshould function. Limited or no access to relevant patient information and the bestmedical evidence about the benefits and risks of treatment options can result inflawed decisions and, more seriously, the suffering of patients. The situation also affectsSDM. If patients are not informed about their health condition, treatment options,benefits and risks or not given high quality information, e.g., becausehealthcare professionals do not have access to the best evidence, patients will be unIIable to assess 'what it is important to them', or they will make inadequate decisionsabout key issues. Consequently, it is almost impossible to practice EBM and SDM ineveryday clinical care.

    For EBM and SDM to serve their purpose, healthcare professionals and patients needinformation systems that provide quick and trouble-free access to all-round information.They also need information systems that can influence the patient/physicianrelationship and facilitate their pursuance of shared goals in the healthcare process,taking into account both illness and personal experience. Hence, based on a qualitativeapproach, this thesis proposes recommendations regarding the redesign of futurehealthcare information systems in ways that will facilitate, rather than hinder,the access to relevant information. One important recommendation identified is thatfuture healthcare information systems must support the core characteristics of EBMand SDM, in an integrated manner, and using the one without the other is notenough. However, such support requires the adoption of a process view on informationsystem development based on the patient's process. A process-oriented approachwith supporting information systems is thus vital for the support of an evidence-based practice where the patient is an important and active collaborator.Moreover, the challenges identified with regard to information system support arenot exclusively technical. Organizational culture, and the attitudes of healthcare professionalsto patient involvement are some of the biggest challenges facing healthcareorganizations.

    Space Matters: A Reflection on Archaeological Theory and Method for Interpreting the Materiality of Space2016Inngår i: Interdisciplinaria Archaeologica, ISSN 1804-848X, E-ISSN 2336-1220, Vol. 7, nr 2, s. 209-216Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Every paradigm in the history of archaeological theory has in some way dealt with space in interpreting the archaeological record; either bringing it into the spotlight or using it to assist description of other observed phenomena. This has resulted in a varied range of approaches to space, but also brought with it inherent problems. Paradigms once regarded as incompatible are now reconciled in mutual coexistence, but maintain little dialogue. Certain methods of spatial analyses have begun to be used as theory-neutral, and space often remains implicitly studied using methods as a set of tools, without exploration of adequate theory.

    The goal of this paper is to present a perspective on how archaeologists may proceed in order to apply both analytical methods to seek patterns in the past and interpret past constructed space. Although space is an intangible entity, it is argued it may be seen as a human-made material culture that plays an active role in social processes. As a case study, I contrast the advantages and shortcomings of several archaeological studies concerned with the spatial structure of the Swahili house. It is argued that we need to actively engage approaches that reveal quantifiable patterns in the built environment, as well as consult more relativistic issues of perception, sensory experience, and social production and consumption of space.

    Pillar Tombs and the City: Creating a Sense of Shared Identity in Swahili Urban Space2018Inngår i: Archaeologies, ISSN 1555-8622, E-ISSN 1935-3987Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper reviews published research on Swahili pillar tombs, as a specific type of tombs built of stone, by summarising records on almost fifty sites on the east coast of Africa. Dated to the 13th–16th centuries AD, the pillar tombs represented a core component of Swahili urban space. By considering their spatial setting, characteristics and comparative case studies from Africa and the Indian Ocean world, the paper reconsiders how pillar tombs might have functioned as a type of material infrastructure for creating social ties and notions of shared identity in a society that has never formally united.

    Drop-out in living lab field test: analyzing consequences and some recommendations2018Inngår i: Twenty-Sixth European Conference on Information Systems (ECIS2018), Portsmouth, UK, 2018, 2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Involving individual users in the process of information systems development is a key dimension of open innovation. Living Labs are socio-technical systems that facilitate information systems development by integrating technical, social and organizational structures and focusing on individuals, tasks, technologies and the interactions between different stakeholders. Testing digital innovations in real-life use context is one of the key components of Living Labs. The users’ motivations to participate in Living Lab field tests at the beginning of the project are usually higher than once the field tests are underway. However, there is a dearth of research on other issues related to participants’ drop-out in Living Lab field tests. This study contributes to the existing literature by investigating the consequences of drop-out in Living Lab field tests and providing recommendations that would facilitate prolonged user engagement. The paper also discusses some ethical considerations regarding involvement of participants within Living Lab field tests. In doing so, we interviewed fourteen Living Lab experts in two Living Labs in Sweden and Belgium. Based on these interviews, we propose a first set of consequences, recommendations and ethical considerations to take into account when setting up Living Lab field tests. Keywords: User

    Med öga för publiken: Moralisk fostran genom heliga Birgittas och de svenska predikanternas exempelberättelser, cirka 1340-15002018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This dissertation is a comparative and deconstructive study of the use of narrative exempla in the Revelations of Saint Birgitta (also known as Saint Bridget of Sweden) and in Swedish sermon collections from the Late Middle Ages. The purpose is to show how Birgitta during the 14th century and Swedish preachers during the 15th century morally educated their audiences through the inclusion of exemplary stories in their works. Furthermore, this dissertation discusses and analyses the ways in which these authors adapted their stories to suite their respective audience. It distinguishes between how Birgitta addressed the worldly and religious leaders of Europe and how the Swedish preachers addressed a socially stratified Swedish congregation by applying Jonathan Cohen’s theory of identification with media characters. This dissertation hereby contributes not only to research concerning the didactics of Christian exemplary literature, but also to the methodology in which audience adaptation in this literature can be evaluated.

    Among the results of this study one finds that the exemplary stories in the Revelations and Swedish sermon collections are often used to rhetorically reinforce doctrinal lessons concerning man’s reciprocal relationship with God. Many of the lessons deal with Christ’s justice, the devil’s evil nature and man’s proper faith and hope in God. However, Birgitta tends to use her stories as analytical explanations for theses lessons, while the Swedish preachers use theirs as simple arguments for them. In view of narrative structure and content, Birgitta tends to focus on describing protagonists’ thoughts and inner disposition in her stories, whereas the Swedish preachers focus on protagonists’ physical course of action in their stories. Moreover, both authors depict international characters, settings and complication motives. Still, Birgitta highlights those associated with the higher estates, while the Swedish preachers emphasize those associated with general church life and the lower laity.

    These results correlate well with strategies suggested in media research for enticing audience identification with characters. In particular, I find that the virtuous or sinful way of life, led by the protagonists in the exemplary stories, mimics that of Birgitta’s and the Swedish preachers’ different target groups. Yet even more strikingly, numerous protagonists are also found to possess attractive heroic ideals. They embody heroic role models, which the authors’ respective audience can be expected to have wished to emulate themselves, and which Birgitta and the Swedish preachers likewise wanted their audience to follow, though to different extents and in different manners. While Birgitta and the Swedish preachers both used exemplary stories to morally educate their recipients in accordance with the Christian exemplary tradition, I thus conclude that their teaching differed in several significant ways, supporting the premise that the authors knew what they wanted to convey, and that they had a good eye for their respective audience.

    Herodotus and the Origins of Political Philosophy: The Beginnings of Western Thought from the Viewpoint of its Impending End2018Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This investigation proposes a historical theory of the origins of political philosophy. It is assumed that political philosophy was made possible by a new form of political thinking commencing with the inauguration of the first direct democracies in Ancient Greece. The pristine turn from elite rule to rule of the people – or to δημοκρατία, a term coined after the event – brought with it the first ever political theory, wherein fundamentally different societal orders, or different principles of societal rule, could be argumentatively compared. The inauguration of this alternative-envisioning “secular” political theory is equaled with the beginnings of classical political theory and explained as the outcome of the conjoining of a new form of constitutionalized political thought (cratistic thinking) and a new emphasis brought to the inner consistency of normative reasoning (‘internal critique’). The original form of political philosophy, Classical Political Philosophy, originated when a political thought launched, wherein non-divinely sanctioned visions of transcendence of the prevailing rule, as well as of the full range of alternatives disclosed by Classical Political Theory, first began to be envisioned. Each of the hypotheses forming the theory – the hypotheses concerning the Ancient Greek beginnings of a “secular”-autonomous political rationale, political theory and political philosophy – is weighed against central evidence provided by the Histories of Herodotus. The passages thus given new interpretations are the Deioces episode in Book I, the Constitutional Debate in Book III and Xerxes’ War Councils in Book VII. Aside from the Herodotean evidence, a range of other relevant Greek literary sources from the archaic and classical ages – e.g. passages from Homer, Hesiod, several pre-Socratic thinkers, Plato and Aristotle – are duly taken into consideration. Included is also a reading of the Mytilenean Debate of Thucydides’ Book III, which shows how the political thought of the classical democracies worked in practice. Finally, the placing of the historical theory against a background of contemporary relevance provides an alternative to all text-oriented approaches not reckoning with the possibility of reaching historically plausible knowledge of real-world events and processes.

    A Taxonomy of Factors Influencing Drop-Out Behaviour in Living Lab Field Tests2018Inngår i: Technology Innovation Management Review, ISSN 1927-0321, E-ISSN 1927-0321, s. 5-21Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The concept of a “living lab” is a relatively new research area and phenomenon that facilitates user engagement in open innovation activities. Studies on living labs show that the users’ motivation to participate in a field test is higher at the beginning of the project than during the rest of the test, and that participants have a tendency to drop out before completing the assigned tasks. However, the literature still lacks theories describing the phenomenon of drop-out within the area of field tests in general and living lab field tests in particular. As the first step in constructing a theoretical discourse, the aims of this study are to present an empirically derived taxonomy for the various factors that influence drop-out behaviour; to provide a definition of “drop-out” in living lab field tests; and to understand the extent to which each of the identified items influence participant drop-out behaviour. To achieve these aims, we first extracted factors influencing drop-out behaviour in the field test from our previous studies on the topic, and then we validated the extracted results across 14 semi-structured interviews with experts in living lab field tests. Our findings show that identified reasons for dropping out can be grouped into three themes: innovation-related, process-related, and participant-related. Each theme consists of three categories with a total of 44 items. In this study, we also propose a unified definition of “drop-out” in living lab field tests.

    Organizing ERS Projects: Implications for Demonstrations and Deployments: A Comparative Stakeholder Analysis of the Swedish ERS-Projects eRoadArlanda and eHighway E162018Rapport (Annet vitenskapelig)
    Abstract [en]

    The electric road system (ERS) receives increasing attention as a potential solution to cope with the transition to environmentally friendly heavy road transport. Moving from the initial technology development phase to the technology demonstration phase has motivated the creation of demonstration projects. Thus, ERS-project organizations have evolved.

    This report makes an inquiry into the organizing of ERS-projects. It is based on a comparative analysis of the two ongoing demonstration projects in Sweden; eRoadArlanda and eHighway E16. The study addresses what implications the current ERS demonstration projects can provide through a stakeholder assessment.

    The outcome of the study is 11 implications for the organizing of ERS demonstration and deployment projects. These are divided among the six perspectives: project leadership, electric road vehicle, electric infrastructure, funding, verification, and interest vs power.

    Patient empowerment and general self-efficacy in patients with coronary heart disease: a cross-sectional study2018Inngår i: BMC Family Practice, ISSN 1471-2296, E-ISSN 1471-2296, Vol. 19, artikkel-id 76Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Abstract

    Background:

    In managing a life with coronary heart disease and the possibility of planning and following a

    rehabilitation plan, patients

    ’ empowerment and self-efficacy are considered important. However, currently there is

    limited data on levels of empowerment among patients with coronary heart disease, and demographic and clinical

    characteristics associated with patient empowerment are not known.

    The purpose of this study was to assess the level of patient empowerment and general self-efficacy in patients six

    to 12 months after the cardiac event. We also aimed to explore the relationship between patient empowerment,

    general self-efficacy and other related factors such as quality of life and demographic variables.

    Methods:

    A sample of 157 cardiac patients (78% male; age 68 ± 8.5 years) was recruited from a Swedish hospital.

    Patient empowerment was assessed using the SWE-CES-10. Additional data was collected on general self-efficacy

    and well-being (EQ5D and Ladder of Life). Demographic and clinical variables were collected from medical records

    and interviews.

    Results:

    The mean levels of patient empowerment and general self-efficacy on a 0–4 scale were 3.69 (±0.54) and

    3.13 (±0.52) respectively, and the relationship between patient empowerment and general self-efficacy was weak

    (

    r = 0.38). In a simple linear regression, patient empowerment and general self-efficacy were significantly correlated

    with marital status, current self-rated health and future well-being. Multiple linear regressions on patient empowerment

    (Model 1) and general self-efficacy (Model 2) showed an independent significant association between patient

    empowerment and current self-rated health. General self-efficacy was not independently associated with any of the

    variables.

    Conclusions:

    Patients with a diagnosis of coronary heart disease reported high levels of empowerment and general

    self-efficacy at six to 12 months after the event. Clinical and demographic variables were not independently associated

    with empowerment or low general self-efficacy. Patient empowerment and general self-efficacy were not mutually

    interchangeable, and therefore both need to be measured when planning for secondary prevention in primary health

    care.

    Trial registration:

    NCT01462799.

    The SwedishNational MarineMonitoringProgramme 2017: HydrographyNutrientsPhytoplankton2018Rapport (Annet vitenskapelig)
    Abstract [en]

    This report presents the main results of the Swedish national marine monitoring programme of the pelagic during 2017. The monitoring data of hydrography, nutrients and phytoplankton are analysed for the seas surrounding Sweden: Skagerrak, Kattegat, The Sound, Baltic Proper, Bothnian Sea and Bothnian Bay. The monitoring is carried out by SMHI (Swedish Meteorological and Hydrological Institute), SU (Stockholm University) and UMF (Umeå Marine Sciences Centre) and the monitoring programme is co-funded by SwAM (Swedish Agency for Marine and Water Management), SMHI, SU and UMF. Data is collected, analysed and reported with support from Swedish environmental monitoring and commissioned by SwaM.

    The Baltic current along the Swedish west coast implies large variations in surface salinity and the unusually large outflow of brackish water from the Baltic Sea in 2017 was reflected as low surface salinity in Skagerrak and Kattegat in the beginning of the year. There were no major deep water inflows to the Baltic Sea during 2017 but a few inflows of minor magnitude. These minor inflows only temporarily improved the oxygen condition in the Bornholm Basin and in the southern part of the Eastern Gotland Basin.

    The salinity below the halocline was above normal in the Gotland Basins and in the Northern Baltic Proper, and also in the surface layer in the Eastern Gotland Basin for almost the whole year.

    In Skagerrak and Kattegat, surface concentrations of phosphate and dissolved inorganic nitrogen were normal while dissolved silica concentrations were elevated especially in spring. In the Baltic Sea, the concentration of silicate in the surface water was elevated in all basins. According to the estimated total content of silicate there has been an increase in silica content in the Baltic Sea since the early 1990’s. Surface concentrations of phosphate were above normal in the Gotland basins and the Northern Baltic Proper while inorganic nitrogen content was above normal in parts of the Arkona and Bornholm basins. During spring and summer, the inorganic nitrogen was consumed at greater depths than usual in the Baltic Proper. In particular concentrations of phosphate and dissolved silica were generally lower than normal in the bottom layer.

    Instead of diatoms, the flagellate genus Pseudochattonella, which is potentially toxic to fish, bloomed in the Kattegat and Skagerrak areas in February – April. During autumn there was a prolonged diatom bloom though. In the Baltic Sea spring bloom occurred in April. The cyanobacteria bloom began in May already with Aphanizomenon flos-aquae. During June and July all three of the filamentous cyanobacteria, A. flos-aquae, Dolichospermum lemmermannii and the potentially harmful Nodularia spumigena were found in the phytoplankton samples in various amounts.

    In the Bothnian Sea, the sea surface temperature during summer was lower than normal and the oxygen conditions in the bottom layer was not critical but still below normal levels.

    Swedish Information Economy: A Preliminary Account2017Inngår i: Dilemmas 2015 Papers from the 18th Annual International Conference Dilemmas for Human Services: Organizing, Designing and Managing / [ed] Sisse Finken, Christina Mörtberg, Anita Mirijamdotter, Vaxjo: LnuPress , 2017Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The recent developments and adoptions of digital technologies give rise to the growth of information economies, understood as an aggregate of economic activities that produce informational outputs. Several key characteristics of an information economy differ to the conventional economic wisdom derived from the industrial age, which may impose governmental policy implications and therefore constitutes a key question: how to govern the newly emerged information economy with the thinking of the industrial age economy. Resolving this problem requires, among others, comprehensive understanding of information economies. To that end, Sweden is among the most advanced adopters of digital technologies and represents therefore a suitable empirical base for the investigation of an information economy. This paper offers preliminary results from a first ever account of the Swedish information economy in terms of its value created, jobs and wages; this account shows that the Swedish economy is dominated by its information economy, which requires a careful attention of policy makers.

    User Awareness of Existing Privacy and Security Risks when Storing Data in the Cloud2015Inngår i: Proceedings of International Conference on E-Learning 15, European Commission, 2015, s. 268-273Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Many studies have ranked the security and privacy of cloud-based systems to be a major concern for their adoption by companies, however, there are not many studies investigating users’ awareness level about these issues. An online study was conducted to study users’ attitude towards privacy and security of data in the cloud-based systems. The research was conducted by delivering an online questionnaire to Computer Science students and employees working in software development companies. The results showed that users in general are aware of existing privacy and security risks when storing data in the cloud, but they lack knowledge when asked to describe those risks and threats in detail. This study indicates a necessity to increase the privacy and security awareness to cloud users about the risks when storing their data in the cloud.

    Analysis of the Flexural Behavior of Textile Reinforced Reactive Powder Concrete Sandwich Elements Using Optical Measurements2018Konferanseproceedings (Fagfellevurdert)
    Abstract [en]

    Prefabricated and non-load bearing sandwich façade elements were developed using Textile Reinforced Reactive Powder Concrete (TRRPC) along with low density Foamed Concrete (FC) and Glass Fiber Reinforced Polymer (GFRP) continuous connecting devices. Four-point bending tests were performed on large-scale TRRPC sandwich element beams to characterize the structural performance, which included the flexural capacity, level of composite action, resulting deformation, crack propagation and failure mechanisms. Optical measurements based on Digital Image Correlation (DIC) were taken simultaneously to enable a detailed analysis of the underlying composite action. The structural behavior of the developed elements was found to be highly dependent on the stiffness and strength of the connectors to ensure composite action between the two TRRPC panels.
