    Towards open source medical devices current situation, inspiring advances and challenges2018In: BIODEVICES 2018 - 11th International Conference on Biomedical Electronics and Devices, Proceedings; Part of 11th International Joint Conference on Biomedical Engineering Systems and Technologies, BIOSTEC 2018, SciTePress, 2018, p. 141-149Conference paper (Refereed)
    Abstract [en]

    Open Source Medical Devices may be part of the solution towards the democratization of medical technologies pursuing Universal Health Coverage as part of the Sustainable Development Goals for United Nations. Recent technological advances, especially in information and communication technologies, combined with innovative collaborative design methodologies and manufacturing techniques allow for the mass-personalization of biodevices and help to optimize the related development times and costs, while keeping safety in the foreground through the whole life cycle of medical products. These advantages can be further promoted by adequately fostering collaboration, communication, high value information exchange, and sustainable partnerships and by extending the employment of open source strategies. To this end, within the UBORA project, we are developing a framework for training the biomedical engineers of the future in open-source collaborative design strategies and for supporting the sharing of information and the assessment of safety and efficacy in novel biodevices. An essential part of this open-source collaborative framework is the UBORA e-infrastructure, which is presented in this study, together with some initial success cases. Main future challenges, connected with regulatory harmonization, with educational issues and with accessible and open design and manufacturing resources, among others, are also presented and discussed.

    Modeling the Effects of ICT on Environmental Sustainability: Revisiting a System Dynamics Model Developed for the European Commission2015In: ICT Innovations for Sustainability / [ed] Hilty, L.M.; Aebischer, B., Switzerland: Springer Publishing Company, 2015, p. 449-474Chapter in book (Refereed)
    Abstract [en]

    This chapter revisits a System Dynamics model developed in 2002 with the aim of exploring the future impacts of Information and Communication Technology (ICT) on environmental sustainability in the EU, which then consisted of 15 countries. The time horizon of the study was 20 years (2000–2020). We analyze the results in light of empirical data that is now available for 2000–2012. None of the three scenarios that were developed by experts to specify the external factors needed to run the model were realistic from today’s point of view. If the model is re-run with more realistic input data for the first half of the simulation period, however, the main results regarding the impact of ICT remain qualitatively the same; they seem to be relatively robust implications of the causal system structure, as it is represented in the model. Overall, the impacts of ICT for mitigating greenhouse gas emissions and other environmental burdens for 2020 tend to be slightly stronger if the simulation is based on the empirical data now available.

    Modelling Rebound Effects in System Dynamics2014In: Proceedings of the 28th Conference on Environmental Informatics - EnviroInfo 2014 - ICT for Energy Efficiency / [ed] Marx Gómez, J., Sonnenschein, M., Vogel, U., Winter, A., Rapp, B., Giesen, N., Germany: BIS Oldenburg, 2014Conference paper (Refereed)
    Abstract [en]

    The induction of demand by increasing the efficiency of a production or consumption process is known as the rebound effect. Feedback loops in System Dynamics can be used to conceptualize the structure of this complex phenomenon and also for communicating model-based insights. In passenger transport, the rebound effect can be induced through increased cost efficiency (direct economic rebound) and/or increase in speed (time rebound). In this paper we review and compare two models on environmental effects of passenger transport—including a model on the role of information and communication technology. We highlight the feedback mechanisms used to deal with the rebound effect (price, efficiency, and time rebound).

    Approaching micrometer size graphene flakes on an insulating substrate with STM2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this study, a method for landing with a Scanning Tunneling Microscope (STM) on a µm size ake of graphene was developed. Two approaches were explored, one using physical guides to navigate on the sample and another one using capacitive pickup in the system. We show that with no modication of the STM that was used, we could land on a micrometer size ake of graphene.

    Investigating the impact of agile control mechanisms on learning in scrum teams2017In: Learning and Innovation in Hybrid Organizations: Strategic and Organizational Insights, Springer International Publishing , 2017, p. 213-229Chapter in book (Refereed)
    Abstract [en]

    This chapter aims to explore Management Control Systems (MCS) resulting from the implementation of agile development methods, relying on an established MCS taxonomy. An abductive approach was adopted, considering the shortage of research evaluating the post-adoption effects of agile methods. Four organizations from an international telecommunication firm that implemented agile methods were involved, and 44 individual semi-structured interviews were performed. In addition, 121 free comments from a global survey to the same organizations were used as secondary data. The paper indicates how Scrum, a widespread agile method, implicitly brings multiple enforcing levers of control to a team’s self-regulatory learning processes.

    Challenges Related to the Introduction of Innovative Services in the Market: Mobile Payment Services in the Swedish Retail Industry2015Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Mobile payment services are expected to be the next step of the electronic payment evolution. However, the level of penetration in European countries is lower than expected. The focus of most academic research has been in two main areas: (i) mobile payment adoption by consumers and (ii) technical aspects of the service. Consequently, a number of themes remain under-researched. In order to expand knowledge on reasons that affect the wider penetration of mobile payments, challenges related to the introduction of mobile payment services in the market have been explored in this thesis.

    More specifically, this research has addressed two problem areas: (i) why mobile payments have not been widely adopted by merchants; and (ii) what effects that the introduction of mobile payments has had on the business networks of the involved actors. As an example, we use the mobile payment services applied in the Swedish retail industry. The study is focused on the main groups of stakeholders – the mobile payment providers, the retailers, and the consumers.

    First, this study has helped to identify what different stakeholders expect of mobile payments and how these services correspond to their needs. In order to analyse the expectations of stakeholders, we have developed an analysis framework based on the theory of diffusion of innovations, the Technology Acceptance Model (TAM), and the theory of network externalities. The analysis highlights the expectations of stakeholders and helps to understand what kind of mobile payment service merchants expect and are willing to adopt. One key finding is that existing mobile payment services for retailing could be further improved in order to ensure an enhanced purchasing process for consumers.

    Second, the research has explored the impact of mobile payment services on the business networks. In order to analyse the relationships and cooperation between business actors, and changes in business strategy and network structure, we used the approach proposed by the Industrial Marketing and Purchasing (IMP) Group. The performed analysis illustrates the following changes in the structure of business networks for the traditional payment solutions (bank cards): (i) emergence of new business actors (i.e. independent mobile payment providers); (ii) new roles and activities of business actors; and (iii) exclusion of traditional business actors (i.e. banks) from the mobile payment systems.

    All these changes lead to increased complexity of relationships and increased level of interdependence between business actors within the networks. The following changes in the strategies of involved actors have been identified: (i) mobile payment providers seek to achieve a control over the business network; (ii) the retailers affect strategies of the mobile payment providers; (iii) the marketing strategies of business actors include cross-marketing in different sectors. All these changes result in additional value and enhanced quality of service for consumers.

    In order to analyse a complex and multidisciplinary area such as mobile payments, it is beneficial to use more than one analysis approach. A combination of different complementing methods helps to explore different aspects of the phenomenon and provides a more comprehensive overview of several research aspects.

    This work contributes to the academic research of mobile payment service adoption by merchants through proposing a theoretical analysis framework. More specifically, the research addresses a new area – expectations of retailers when new solutions are introduced. The framework consists of the following criteria and aspects: technological feasibility, economic benefits, lower service costs, added value of services, network externalities and the problem of critical mass, and finally, ease of use. This framework helps to identify what merchants can expect of mobile payment services.

    Another area of contribution is the analysis of the effect that mobile payments make on the actors and business networks of traditional payment services. The introduction of new services results in emergence of new business actors, a need to establish new relationships, and increased complexity of a business network. Moreover, in order to succeed, cooperation between all network actors is needed. As a result, business actors have to adjust their services and strategies according to needs of others.

    Report on the SIGIR workshop on "entertain me": supporting complex search tasks2011In: SIGIR Forum, ISSN 0163-5840, E-ISSN 1558-0229, Vol. 45, no 2, p. 51-59Article in journal (Refereed)
    Abstract [en]

    Searchers with a complex information need typically slice-and-dice their problem into several queries and subqueries, and laboriously combine the answers post hoc to solve their tasks. Consider planning a social event at the last day of SIGIR, in the unknown city of Beijing, factoring in distances, timing, and preferences on budget, cuisine, and entertainment. A system supporting the entire search episode should "know" a lot, either from profiles or implicit information, or from explicit information in the query or from feedback. This may lead to the (interactive) construction of a complexly structured query, but sometimes the most obvious query for a complex need is dead simple: entertain me. Rather than returning ten-blue-lines in response to a 2.4-word query, the desired system should support searchers during their whole task or search episode, by iteratively constructing a complex query or search strategy, by exploring the result-space at every stage, and by combining the partial answers into a coherent whole.

    The workshop brought together a varied group of researchers covering both user and system centered approaches, who worked together on the problem and potential solutions. There was a strong feeling that we made substantial progress. First, there was general optimism on the wealth of contextual information that can be derived from context or natural interactions without the need for obstrusive explicit feedback. Second, the task of "contextual suggestions"--matching specific types of results against rich profiles--was identified as a manageable first step, and concrete plans for such as track were discussed in the aftermath of the workshop. Third, the identified dimensions of variation--such as the level of engagement, or user versus system initiative--give clear suggestions of the types of input a searcher is willing or able to give and the type of response expected from a system.

    From transactions to relationships: Making sense of user-centered perspectives in large technology-intensive companies2015In: 4th IFIP 13.6 Working Conference on Human Work Interaction Design, HWID 2015, Springer-Verlag New York, 2015, p. 114-124Conference paper (Refereed)
    Abstract [en]

    In this paper we analyze interviews from four technology-intensive companies, focused on service and service development. All companies have during the last two decades introduced interaction design units, and the corporations were selected due to their interest in also expanding the service share of their business. This service shift has been a top-down initiative. However in only two companies, the initiatives have led to the establishment of enterprise wide service development processes, and in the other two companies, the service development is more ad hoc. It is argued that even if interaction design has close theoretical relation to service design such combination has so far been limited. We discuss the shift from product to service view of the offerings within these companies, and relate this to user-centered perspectives. We argue there is a window of opportunity within technology-intensive and engineering focused industries to include user-centered design when formalizing service development.

    The sharing economy as the commons of the 21st century2017In: Cambridge Journal of Regions, Economy and Society, ISSN 1752-1378, E-ISSN 1752-1386, Vol. 10, no 2, p. 231-247Article in journal (Refereed)
    Abstract [en]

    This article aims to make a contribution to the debate on how contemporary collaborative commons, as part of the wider sharing economy, can be understood and supported. Three cases of contemporary commons are analysed: a DIY bike repair studio, a pop-up home office concept and Wikipedia. The article shows how the design principles developed for governing natural resource commons are only partly applicable to these contemporary commons. It also illustrates the differences in these types of commons in terms of the nature of the resource being shared, scarcity, barriers to entry and how rules are formulated and upheld.

    Assembly work settings enabling proactivity - Information requirements2008In: MANUFACTURING SYSTEMS AND TECHNOLOGIES FOR THE NEW FRONTIER / [ed] Mitsuishi, M Ueda, K Kimura, F, SPRINGER , 2008, p. 203-+Conference paper (Refereed)
    Abstract [en]

    Information is a critical factor to support a proactive behaviour of operators in complex work settings characterized by flexible levels of automation and need for knowledge-based decision making. In this conceptual paper the authors define proactive behaviour as the ability of operators to control a situation by taking action in advance. Information requirements that enable proactivity and different control behaviour are identified. Moreover, several demands on the information support system are outlined. Further, the paper presents some implications for management as a result of the new work role of the operator regarding decision making, planning, and control.

    Abstract [en]

    This paper looks at the changing shape of mobile connectivity and how it has influenced the potential for informing on sustainable travel. It examines the role mobile connectivity has had for an ICT based service informing on traffic and transport in order to trace what role social practices of interconnecting through mobile media may have had for such an enterprise. The paper looks at two historical examples of ICT based traffic and travel information services in Stockholm, Sweden in order to discuss what role mobile connectivity may have for promoting sustainable travel through ICT.

    From Maps to Apps: Tracing the Organizational Responsiveness of an Early Multi-Modal Travel Planning Service2015In: The Journal of urban technology, ISSN 1063-0732, E-ISSN 1466-1853, Vol. 22, no 4, p. 87-101Article in journal (Refereed)
    Abstract [en]

    An Internet-based system for informing on multimodal travel planning (several modes of transportation) was introduced in Stockholm, Sweden in October 2000 in the form of a web page called trafiken.nu. The web page has a historical value of being one of the first attempts in Europe, and possibly the world, at providing an ICT-based travel planning service geared towards facilitating sustainable travel to the general public. The aim of this article is to investigate the historical development of trafiken.nu in order to draw lessons on how to better provide for a public information service with a potential for facilitating sustainable travel planning. Findings from the study of trafiken.nu suggest that the organizations behind the service have been slow in adapting to shifting media technology practices on how to provide for information which has affected the uptake of the service. Lessons from the case study provide a basis for arguing that organizations attempting to implement public information services would benefit from finding a means of harnessing collective intelligence in order to provide for a more customizable and responsive service to the general public.

    From Vision to Transition: Exploring the Potential for Public Information Services to Facilitate Sustainable Urban Transport2014Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Background: Policy initiatives to promote sustainable travel through the use of Internet based public information systems have increased during the last decade. Stockholm, in being one of the first cities in Europe to implement an Internet based service for facilitating sustainable travel is believed to be a good candidate for an analysis of key issues for developing sustainable travel planning services to the public.

    Aim: This thesis investigates the past development of two Stockholm based public information systems and their services in order to draw lessons on how to better provide for a public information service geared towards facilitating  environmentally sustainable travel planning through information and communications technology. The overall goal of the thesis is to contribute to an understanding on how to better design and manage current and future attempts at facilitating sustainable travel planning services based on historical case studies.

    Approach: The thesis draws ideas from the concept of organizational responsiveness – an organization’s ability to listen, understand and respond to demands put to it by its internal and external stakeholders – in order to depict how well or not the two public information systems and their owners have adapted to established norms and values of their surroundings.

    Results: Overall, the findings from the historical case studies suggest that organizations attempting to provide sustainable travel planning to the public need to design and manage their systems in such a way that it responds to shifting demands on how to provide for information. Implementing and embedding new technologies involves complex processes of change both at the micro level – for users and practitioners of the service – and at the meso level for the involved public service organizations themselves. This condition requires a contextualist framework to analyze and understand organizational, contextual and cultural issues involved in the adoption of new technologies and procedures.

    Conclusions: The thesis concludes with a discussion on how the findings from the historical case studies may provide lessons for both current and future attempts at providing public information systems geared towards facilitating environmentally sustainable travel planning to the public. Historical examples and issues concerning collective intelligence and peer to peer based forms of designing, producing and supervising public information services identified throughout the study are looked upon and discussed in terms of their possible role in increasing the potential for public information services to facilitate sustainable urban transport.

    Traffic Radio as a Precursor to Smart Travel Planning Systems: The Challenge of Organizing “Collective Intelligence”2013In: The Journal of urban technology, ISSN 1063-0732, E-ISSN 1466-1853, Vol. 20, no 4, p. 43-55Article in journal (Refereed)
    Abstract [en]

    This paper depicts how a Swedish radio station organized a means of real-time information management to report on local traffic conditions long before the common use of the Internet. Drawing on a history of the Stockholm traffic radio staff the study examines particular conditions for organizing a service that may inform next generations of smart travel planning systems. The author notes how a vision of involving the public together with the use of increasingly mobile and interconnected communication devices provided the service with an opportunity for harnessing collective intelligence. The study highlights critical success factors and barriers for organizing collective  intelligence and the importance they may have had for providing a real-time information service to the public.

    Association between Polyelectrolytes and Oppositely Charged Surfactants in Bulk and at Solid/Liquid Interfaces2010In: Colloids and Interface Science Series, Wiley-Blackwell, 2010, Vol. 3, p. 337-395Chapter in book (Other academic)
    Abstract [en]

    Mixtures of polyelectrolytes and oppositely charged surfactants find applications in many processes and products that are used in our daily life. Such systems also show many interesting features from a scientific point of view. Due to the combined technological relevance and scientific challenge, considerable research efforts have been made in this area in recent years. This has resulted in new theoretical approaches, the development of simulation methods and new experimental techniques and, of course, a large body of new findings. Together, these efforts have increased the understanding significantly, especially during the last 5 years. This chapter reviews some aspects of this topic, focusing on bulk association and association at solid/liquid interfaces. The review is focused on developments during the 21st century, even though in some cases a historical perspective is also offered.

    Clustering e-mails for the Swedish social insurance agency - What part of the e-mail thread gives the best quality?2010In: Advances in Natural Language Processing: 7th International Conference on NLP, IceTAL 2010, Reykjavik, Iceland, August 16-18, 2010, Springer Berlin/Heidelberg, 2010, p. 115-120Conference paper (Refereed)
    Abstract [en]

    We need to analyse a large number of e-mails sent by the citizens to the customer services department of a governmental organisation based in Sweden. To carry out this analysis we clustered a large number of e-mails with the aim of automatic e-mail answering. One issue that came up was whether we should use the whole e-mail including the thread or just the original query for the clustering. In this paper we describe this investigation. Our results show that only the query and the answering part should be used, but not necessarily the whole e-mail thread. The results clearly show that the original question contains more useful information than only the answer, although a combination is even better. Using the full e-mail thread does not downgrade the result.

    Change management: Blended learning adoption in a large network of European universities2018In: Proceedings of the International Conference on e-Learning, ICEL, Academic Conferences Limited, 2018, p. 77-83Conference paper (Refereed)
    Abstract [en]

    We report in this paper on a multiyear endeavour within the EIT (European Institute of Innovation and Technology) Digital community, during which EIT Digital built an international community of Innovation and Entrepreneurship (“I&E”) teachers at Master level by implementing a blended learning strategy. We see this challenge as a case in change management, which could offer relevant insight to run similar initiatives of blending learning adoption as an enabler to developing pedagogical cooperation in networks of universities with real impact on practices. Through the lenses of change management theory, we describe and analyse the methods that allowed EIT Digital to create and enhance a community of “teacher-producers” in order to develop and deploy blended education from scratch. EIT Digital, a Knowledge and Innovation Community of the European Institute of Innovation and Technology (EIT), provides IT education at Master’s level since 2013 and in association with its around 20 member universities, including a strong “Innovation & Entrepreneurship” (“I&E”) education component. EIT Digital developed a blended learning strategy whose originality came from the fact that some of the teachers are also producers on behalf of the entire community, receiving associated co-funding and technical support from EIT Digital. More specifically, teachers actively took part to the production agenda, according to which producers were chosen within the community to create and deliver the agreed online contents. EIT Digital library now encompasses more than 500 basic online contents (“nuggets”) covering most topics relevant for I&E education at the graduate level, from basic business model introductions to complex technology transfer strategies. This amounts to more than 45 hours’ worth of videos along with dozens of written cases, quizzes and other forms of online/offline assignments. Depending on the various universities’ contexts, different blending strategies were deployed, which had practical consequences on the global EIT Digital development. The heterogeneity of the universities’ profiles probably significantly increased the value of the EIT Digital network which proved relevant with regards to blended learning adoption, while EIT Digital’s change management strategy contributed significantly to uplifting the I&E education offered at the member universities, notably giving momentum to its I&E teacher community.

    Design for the value of safety2015In: Handbook of Ethics, Values, and Technological Design: Sources, Theory, Values and Application Domains, Springer Netherlands, 2015, p. 491-511Chapter in book (Other academic)
    Abstract [en]

    Two major methods for achieving safety in engineering design are compared: safety engineering and probabilistic risk analysis. Safety engineering employs simple design principles or rules of thumb such as inherent safety, multiple barriers, and numerical safety margins to reduce the risk of accidents. Probabilistic risk analysis combines the probabilities of individual events in event chains leading to accidents in order to identify design elements in need of improvement and often also to optimize the use of resources. It is proposed that the two methodologies should be seen as complementary rather than as competitors. Probabilistic risk analysis is at its advantage when meaningful probability estimates are available for most of the major events that may contribute to an accident. Safety engineering principles are more suitable to deal with uncertainties that defy quantification. In many design tasks, the combined use of both methodologies is preferable.

    The activity of human metadata creation and the Semantic Web2015In: International Journal of Metadata, Semantics and Ontologies, ISSN 1744-263X, Vol. 10, no 2, p. 64-74Article in journal (Refereed)
    Abstract [en]

    This paper presents an explorative study of the human activity of creating metadata, done with the purpose of exploring the practices of this activity and how those can potentially impact the utility of the metadata as it is exposed on a level that enables semantic collaboration, like the Semantic Web. Previous research around human metadata creation seems to indicate that how the activity is carried out has a common core, but is unique in each situation on how it can be improved. The data for this study was gathered through interviews and analyzed using activity theory. The analysis of the data gathered through the interviews indicate that the main objective of the activity is to enable discovery within a collection. Metadata is however created with a community of users in mind, which is sometimes reflected in metadata creation guidelines. These guidelines can in turn impact the discoverability across these communities as metadata is exposed on the Semantic Web.

    Worlds Apart and Close Together: Relating mechatronics and project management research2018In: Proceedings of International Design Conference, DESIGN, 2018, p. 2867-2878Conference paper (Refereed)
    Abstract [en]

    While they originate from different contexts and values, the Mechatronic and Project Management research communities are both committed to the study of the process of complex engineering systems design. These two fields have generally been engaged in their research separated from each other. Recently, calls have been heard from both to end such disciplinary separation. This paper seeks to conceptually relate the two research communities, seeking to understand how they can be seen as different, related and inclusive of each other through offering three conceptual models of their relationships.

    Evaluating IT Service Delivery amongst ISPs from Nicaragua2010In: 16th Americas Conference on Information Systems 2010, AMCIS 2010: Volume 2, 2010, p. 1464-1472Conference paper (Refereed)
    Abstract [en]

    This paper presents an evaluation of IT service delivery by Internet Service Providers (ISPs) from Nicaragua at the end of 2009. The evaluation is supported by a methodological approach based on IT Infrastructure Library (ITIL) v.2 concepts and case study techniques. The evaluation involved three ISPs that are nation-wide Internet Service Providers with more than ten years running. We describe the current practices and limitations of IT service delivery in ISPs from Nicaragua. Finally, we argue that existing IT service delivery practices amongst ISPs have matches to ITIL processes, although the ITIL processes are not known amongst them.

    Abstract [sv]

    De många snabbt växande städerna världen över utkämpar en ojämn kamp mot stegrade trafikvolymer, svårartad trängsel och allvarliga miljöproblem. . Det har visat sig omöjligt att hålla jämna steg med efterfrågan och att uppfylla uppställda miljömål. Långt över en miljard människor drabbas dagligen. Försöken att påverka efterfrågan har hittills bara haft marginella effekter. Med hjälp av ett integrerat informations- och betalsystem och dynamisk prissättning i realtid skulle stora framsteg kunna göras. Stockholmsregionen som redan infört trängselskatt har goda möjligheter att ta täten i försöken att skapa en hållbar stadstrafik.

    Institutionalizing human-computer interaction for global health2017In: Global Health Action, ISSN 1654-9716, E-ISSN 1654-9880, Vol. 10, article id 1344003Article in journal (Refereed)
    Abstract [en]

    Digitalization is the societal change process in which new ICT-based solutions bring forward completely new ways of doing things, new businesses and new movements in the society. Digitalization also provides completely new ways of addressing issues related to global health. This paper provides an overview of the field of human-computer interaction (HCI) and in what way the field has contributed to international development in different regions of the world. Additionally, it outlines the United Nations' new sustainability goals from December 2015 and what these could contribute to the development of global health and its relationship to digitalization. Finally, it argues why and how HCI could be adopted and adapted to fit the contextual needs, the need for localization and for the development of new digital innovations. The research methodology is mostly qualitative following an action research paradigm in which the actual change process that the digitalization is evoking is equally important as the scientific conclusions that can be drawn. In conclusion, the paper argues that digitalization is fundamentally changing the society through the development and use of digital technologies and may have a profound effect on the digital development of every country in the world. But it needs to be developed based on local practices, it needs international support and to not be limited by any technological constraints. Particularly digitalization to support global health requires a profound understanding of the users and their context, arguing for user-centred systems design methodologies as particularly suitable.

    Using Meta-agents to Reason with Multiple Ontologies2008In: AGENT AND MULTI-AGENT SYSTEMS: TECHNOLOGIES AND APPLICATIONS, PROCEEDINGS / [ed] Ngoc Thanh Nguyen, GeunSik Jo, Robert J. Howlett, Lakhmi C. Jain, Springer Berlin/Heidelberg, 2008, p. 261-270Conference paper (Refereed)
    Abstract [en]

    The semantic web uses ontologies to improve searching since ontologies provide a richer semantic model of content by expressing terms and relationships. However, a problem with the web is the large number of ontologies, which complicates searching. To maximize the capability of the search, the ontologies need to be combined to obtain complex answers. Usually, the ontologies are created without following any guidelines and, therefore, combining them is not a simple task, especially when ensuring a consistent result. We propose using meta-agents on top of software agents in a multi-agent system to resolve the use and the combination of multiple ontologies and to enable searching and reasoning. The software agents search for parts in the ontologies corresponding to the user-request and meta-agents combine the results from the agents. The meta-agents also partition the ontologies into consistent sets and then combine multiple ontologies into meaningful and logically consistent structures. For this purpose, we extend an existing mapping and alignment algorithm used for communication between agents. The use of multi-agents gives advantages since they provide a parallel approach and, thereby, efficiently handle large numbers of ontologies in order to accomplishtasks separately.

    A peek into the black box: exploring classifiers by randomization2014In: Data mining and knowledge discovery, ISSN 1384-5810, E-ISSN 1573-756X, Vol. 28, no 5-6, p. 1503-1529Article in journal (Refereed)
    Abstract [en]

    Classifiers are often opaque and cannot easily be inspected to gain understanding of which factors are of importance. We propose an efficient iterative algorithm to find the attributes and dependencies used by any classifier when making predictions. The performance and utility of the algorithm is demonstrated on two synthetic and 26 real-world datasets, using 15 commonly used learning algorithms to generate the classifiers. The empirical investigation shows that the novel algorithm is indeed able to find groupings of interacting attributes exploited by the different classifiers. These groupings allow for finding similarities among classifiers for a single dataset as well as for determining the extent to which different classifiers exploit such interactions in general.

    Navigating the development and dissemination of internet cognitive behavioral therapy (iCBT) for anxiety disorders in children and young people: A consensus statement with recommendations from the #iCBTLorentz Workshop Group2018In: Internet Interventions, ISSN 2214-7829, Vol. 12, p. 1-10Article in journal (Refereed)
    Abstract [en]

    Initial internet-based cognitive behavioral therapy (iCBT) programs for anxiety disorders in children and young people (CYP) have been developed and evaluated, however these have not yet been widely adopted in routine practice. The lack of guidance and formalized approaches to the development and dissemination of iCBT has arguably contributed to the difficulty in developing iCBT that is scalable and sustainable beyond academic evaluation and that can ultimately be adopted by healthcare providers. This paper presents a consensus statement and recommendations from a workshop of international experts in CYP anxiety and iCBT (#iCBTLorentz Workshop Group) on the development, evaluation, engagement and dissemination of iCBT for anxiety in CYP.

    Grey Energy and Environmental Impacts of ICT Hardware2015In: ICT Innovations for Sustainability / [ed] Lorenz M. Hilty, Bernard Aebischer, Switzerland: Springer, 2015, p. 171-189Chapter in book (Refereed)
    Abstract [en]

    Direct energy consumption of ICT hardware is only “half the story.” In order to get the “whole story,” energy consumption during the entire life cycle has to be taken into account. This chapter is a first step toward a more comprehensive picture, showing the “grey energy” (i.e., the overall energy requirements) as well as the releases (into air, water, and soil) during the entire life cycle of exemplary ICT hardware devices by applying the life cycle assessment method. The examples calculated show that a focus on direct energy consumption alone fails to take account of relevant parts of the total energy consumption of ICT hardware as well as the relevance of the production phase. As a general tendency, the production phase is more and more important the smaller (and the more energy-efficient) the devices are. When in use, a tablet computer is much more energy-efficient than a desktop computer system with its various components, so its production phase has a much greater relative importance. Accordingly, the impacts due to data transfer when using Internet services are also increasingly relevant the smaller the end-user device is, reaching up to more than 90 % of the overall impact when using a tablet computer.

    Abstract [en]

    Meta-level agents and intelligent agents in multi-agent systems canbe used to search for solutions in networks and graphs where the meta-agentsprovide paths between nodes based on properties of the graph elements given atthe time. A challenge with network problems is finding these search paths whileextracting information in the network within an acceptable time bound.Moreover, this is especially difficult when information is extracted andcombined from several different sources. Reducing time and making the agentswork together requires a plan or an effective algorithm. In this paper wepropose an approach to an event-driven algorithm that can search forinformation in networks using meta-agents in multi-agent systems. The metaagentsmonitor the agents using event-driven communication, acting as a searchmethod and extract the searching for information in networks.

    Corporate Social Networks within the Financial Sector: A tool to enhance unity and knowledge sharing2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study has been conducted with Sirius International as a case company. The investigation has revolved around the weaknesses Sirius, along with the authors, have identified concerning the international collaboration and communication. It was later shown that these problems were based on a low sense of unity in the organization as a result of the lack of knowledge sharing, knowledge management, and spread of organization related information. It was decided to evaluate whether a corporate social network (CSN) could assist in these problems and if so, decide what system would be the most appropriate in regards to the internal needs and requirements at Sirius. The major challenges brought on with an implementation of a CSN, and how to face these, were investigated as a part of the evaluation whether a CSN would be appropriate for Sirius or not.

    The study showed that a CSN was an appropriate choice for Sirius in order to improve the international communication, collaboration, and unity. The most suitable choice was determined to be Yammer, as it best suited the internal requirements and needs. Along with these results, the largest challenge with an implementation and future use of the system was user acceptance and overall usage of the system. If the CSN is not used, none of the visions, goals, or purposes will be fulfilled.

    "Sorry, what was your name again?": How to Use a Social Robot to Simulate Alzheimer’s Disease and Exploring the Effects on its Interlocutors2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Machines are designed to be infallible, but what happens if they are suddenly struck by chronic mental decline such as dementia? In this research, a social robot has been transformed into a mild-stage Alzheimer’s patient. The ultimate goal is to use it as a training tool for caregivers and medical students, as well as to raise general awareness for the disease. In particular, the study aimed to identify how to simulate Alzheimer’s with a social robot and what the effects are on its conversation partners. Thanks to its properties, the back-projected robotic head Furhat was the ideal candidate to adopt the role of Max. The sources of inspiration derived from interviews and observations. A Wizard of Oz setup enabled a conversation between the character and the user, who was given the task of asking about the robot’s life. To allow for in-between subject comparisons, the set of 20 participants was a mixture of medical and non- medical students, as well as people who knew someone with dementia closely and those who never met any. The experience was evaluated through pre- and post-interviews along with user observations. The results indicate that the patient simulation was convincing, leading the users to treat the machine as a human being and develop an emotional bond to it. They remained patient in spite of the robot’s symptoms, which affirms its potential for educational use. After all, this project aims to inspire researchers to find solutions in unconventional ways.

    HTO - A complementary ergonomics approach2017In: APPLIED ERGONOMICS, ISSN 0003-6870, Vol. 59, p. 182-190Article in journal (Refereed)
    Abstract [en]

    The field of human factors and ergonomics constitutes a strong potential in systems analysis, design and improvement. However, it is difficult to communicate its potential value. This paper addresses how the human-technology-organization (HTO) concept can be defined and supports the understanding, communication and development of the systems' character and potential of human factors and ergonomics. Empirical examples from the authors' experiences of working with the HTO concept in R&D and teaching are illustrated, including its usefulness as: 1) a conceptual model; 2) an analysis framework; 3) a meta methodology; 4) a pedagogical tool; and 5) a design tool. The use of HTO provides guidance on how the system can be designed to better support health, individual and systems performance. It is further suggested that there is a strong potential for developing the theory, applications and methodological aspects of HTO.

    Enhancing the Value Proposition of Live Esports Consumption with AI Technology2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When a company includes a new technology or innovation into their value proposition, customers may perceive it as an enhancement or deterioration. This phenomenon was explored in this study with a case study of a present case in the esports industry. Research have shown that AI (Artificial Intelligence) technology can be used to predict which team is going to win in a match in the esports game DotA 2. A prototype AI called Znipe Sense was developed and analyzed during this study to answer the question: How can a predictive AI affect the value proposition of live esports consumption? Znipe Sense was included into Znipe Esports’ value proposition during a tournament in February 2018. It was observed that Znipe Sense could predict outcomes of professional matches with a higher accuracy than human experts. The observations of Znipe Sense, an interview with experienced players, interviews with business professionals and internal company documents were used as empirical material for the analysis. How Znipe Sense affected the value proposition was analyzed through the factors: Performance, Ease-of-use, Reliability, Flexibility and Affectivity, also known as the PERFA framework. It was concluded that a predictive AI can enhance the value proposition of live esports consumption through the Performance and Ease-of-use factors, and it would not affect the value proposition through Reliability or Flexibility. However, in the analysis of the Affectivity factor it was identified that there is a risk related to negative effects of gambling addiction that could deteriorate the value proposition.

    Digital Marketing Strategy: B2B and Stakeholders Communication2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Since digital media entered the business domain, many different tools and platforms have transformed the nature of business communications. This transformation has not been easy, since the journey has been accompanied by challenges from the marketers’ side against the adoption of the new platforms into the firm’s communication channels. Business to business marketers have also been engaged in such challenges by maintaining a slow adoption, which has motivated the researchers to study the adoption of different means and tools of digital communication in a business context.

    Through this research, I contribute by exploring the adoption strategies of digital platforms in the B2B supply chain including B2B firms, retailers and end users. By digital media, I mainly refer to social media and beacon technology. First, I begin this thesis by identifying the adoption and integration strategies of social media and digital marketing into traditional marketing channels in a B2B context. In this part, I identify the B2B firms’ target audience and propose a model facilitating a B2B firm’s practical social media adoption strategies.

    Second, to explore the benefits of different social media content sharing approaches derived from information accessibility resulted in the prior study of this thesis, I introduce and examine Public and Gated-Content sharing approaches. Thereafter, assisted by Social Power Theory and Resource Dependence Theory, I examine the effect of Public and Gated-Content sharing approaches on the target audience’s willingness to interact with the firm. The findings of this study reveal that Gated-Content approach can help the firms build closer relationship with the target audience and engage them in a co-creation process.

    Third, by studying proximity marketing through the adoption of beacon technology in the retail context, I explore the current methods of usage, as well as the benefits and challenges of in-store proximity marketing adoption for content sharing purposes. I complete the thesis by presenting the different challenges of such adoption, which consist technical, human behavior, managerial perception, resource and privacy factors. Finally, I identify the need to integrate the physical aspect of place and location back again into the online digital communication channels within a retail context.

    Optimal contracting under adverse selection: The implications of mentalizing2015In: Współczesna Ekonomia, ISSN 1897-9254, Vol. 9, no 2, p. 215-232Article in journal (Refereed)
    Abstract [en]

    We study a model of adverse selection, hard and soft information, and mentalizing ability—the human capacity to represent others’ intentions, knowledge, and beliefs. By allowing for a continuous range of different information types, as well as for different means of acquiring information, we develop a model that captures how principals differentially obtain information on agents. We show that principals that combine conventional data collection techniques with mentalizing benefit from a synergistic effect that impacts both the amount of information that is accessed and the overall cost of that information. This strategy affects the properties of the optimal contract, which grows closer to the first best. This research provides insights into the implications of mentalizing for agency theory.

    Towards circular economy implementation: a comprehensive review in context of manufacturing industry2016In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 115, p. 36-51Article, review/survey (Refereed)
    Abstract [en]

    The concept of circular economy (CE) is to an increasing extent treated as a solution to series of challenges such as waste generation, resource scarcity and sustaining economic benefits. However the concept of circularity is not of novel as such. Specific circumstances and motivations have stimulated ideas relevant to circularity in the past through activities such as reuse, remanufacturing or recycling. Main objectives of this work are: to provide a comprehensive review of research efforts encompassing aspects of resources scarcity, waste generation and economic advantages; to explore the CE landscape in the context of these three aspects especially when they are considered simultaneously; based on an idea of a comprehensive CE framework, propose an implementation strategy using top-down and bottom-up approach in a concurrent manner. To fulfill this objective a comprehensive review of state-of-the-art research is carried out to understand different ideas relevant to CE, motivation for the research and context of their recurrence. Main contributions of this paper are a comprehensive CE framework and a practical implementation strategy for a regenerative economy and natural environment. The framework emphasizes on a combined view of three main aspects i.e. environment, resources and economic benefits. It also underlines that joint support of all stakeholders is necessary in order to successfully implement the CE concept at large scale. The proposed framework and implementation strategy also identify new avenues for future research and practice in the field of CE.

    Framework for Dynamic Life Critical Situations Using Agents2009In: Multi-Agent System Technologies, Proceedings / [ed] Lars Braubach, Wiebe van der Hoek, Paolo Petta, Alexander Pokahr, Springer Berlin/Heidelberg, 2009, p. 214-219Conference paper (Refereed)
    Abstract [en]

    In this paper, we present a framework incorporating a multi-agent system (MAS) that enables aid for international effect-based operation in emergency situations. The outcome is to empower emergency personnel, which can support collaboration between different international services by informing them about the emergency, matching competences and resources of the teams and volunteers. The challenge in emergency contexts is the abbreviations forming an information-carrying structure, which is especially important when abbreviations are exchanged between different services like rescue, military and emergency. We propose a framework, which provides the right information, rescue team, and services at the right place. The MAS can support information dissemination in dynamic situations in context, based on the information extraction and matching of the contents of the underlying ontologies. In the framework the system poses a sensible solution to the international rescue teams' need of a high quality handling of life critical situations.

    A method for analyzing IT service strategy in municipal governments from nicaragua2010In: 16th Americas Conference on Information Systems 2010, AMCIS 2010, 2010, p. 2966-2978Conference paper (Refereed)
    Abstract [en]

    The importance of IT strategy is generally accepted, though in practice this may vary from one IT organization to another. The design of a formal IT strategy may be required or not, depending on the environment, but, independently of this, strategic decisions still must be made and therefore strategic practices are performed. In order to make any improvement in strategic practices, awareness of their current state in the IT organization is needed. This paper proposes a method for analyzing IT service strategy in the context of IT organizations in municipal governments; the main issues considered are both people- and organization-related (e.g. internal service providers, prioritized cost-effectiveness, current practices oriented to tactical and operational activities, etc.). This method decomposes the analysis from two different perspectives: strategic practices in use and maturity level of such practices. The method was tested in two municipal governments from Nicaragua.

    Approach to Solving Security Problems Using Meta-Agents in Multi Agent System2008In: AGENT AND MULTI-AGENT SYSTEMS: TECHNOLOGIES AND APPLICATIONS, PROCEEDINGS / [ed] Ngoc Thanh Nguyen, GeunSik Jo, Robert J. Howlett, Lakhmi C. Jain, Springer Berlin/Heidelberg, 2008, p. 122-131Conference paper (Refereed)
    Abstract [en]

    In this paper, we present an approach of integrating meta-agents in Web Services. Web Services requires an appropriate level of security to support business systems to be used by anyone, anywhere, at anytime and any platform. However, the increased use of distributed systems with message passing produces a growing set of security problems. This especially concerns threats and attacks on Web Services consisting of transactions with valuable resources. To prevent possible attacks on Web Services, we propose using meta-agents over software agents in a multi-agent system. The multi-agent system consists of a network of software agents that secure the message passing at the transport and application levels. To avoid attacks on these agents, we use meta-agents to monitor the software agents’ actions and then to direct the software agents’ work. These meta-agents are also used to handle unexpected events in the actions of the software agents.

    Abstract [en]

    Adult content is pervasive on the Web, has been a driving factor in the adoption of the Internet medium. It is responsible for a significant fraction of traffic and revenues, yet rarely attracts attention in research. We propose that the research questions surrounding adult content access behaviors are unique, and we believe interesting and valuable research in this area can be done ethically. The workshop on Search and Exploration of X-Rated Information (SEXI) addresses these issues for information access tasks related to adult content.

    Uppnå Prestanda för Beräkningsintensiva Tjänster i SaaS2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Enterprise business applications are following a rapid trend to move their solution model from specic organizational users to global access. This creates opportunities for organization to expand geographically with partners and resellers but it also increases simultaneous user requests. These solution models are commonly based on many data-set states and a web applications that perform multiple tasks in its work-ow including compute intensive requests to separate Compute Intensive Services (CIS). This research is based on these solution models and a special type of CIS that build and reuse in-memory cache to reduce response latency. Performance factors like additional simultaneous requests and cache building requests can increase response latency if not enough CIS are available to handle load peaks. Additional compute services can be added to the infrastructure but such solutions increase cost and these additional services are not required all the time. Main goal of this research is to study and design an architecture to achieve cost-e ective performance for solution model of CIS. First, a study have been performed on dedicated servers approach, to nd impact of these performance factors. Next, a prototype Software as a Service (SaaS) architecture has been presented which detects and reduces load peaks created by performance factors. SaaS architecture has been designed by using cloud computing products of Amazon Web Services (AWS). Few supplementary components have been identied and developed during research to overcome shortcomings of standard cloud products. It aims to reduce load peaks with scalability and elasticity. Experiments have been performed on SaaS architecture to and its advantages and limitations for solution model of CIS. An essential part of this research are two solution proposals, which are based on designed SaaS architecture. First solution proposal has been made for multi-tenant architecture because multi-tenancy can help to enhance cost-effective performance. The second solution proposal has been made to achieve low latency response by optimizing usage of in-memory cache. This optimization can help enterprises to change data-set states more often and achieve predictable low latency. It also adds exibility in SaaS architecture to reduce number of required servers.

    A Needs-Based Approach towards Fostering Long-term Engagement with Energy Feedback among Local Residents2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In order to reach the current climate goals, energy consumption needs to decrease in all sectors, including households, which produce 20% of the European emissions. However, it is difficult to increase residents’ engagement in their household electricity consumption as it is an ‘invisible’ form of energy, the monetary incentives are often too small and environmental incentives are not very effective. Building on the idea that an engagement mechanism should be based on user needs, and recent research showing that social influence can be an effective way to affect consumption behaviour, this thesis examines the potential of a neighbourhood-based digital local social network providing feedback on household electricity consumption as an engagement solution. By helping neighbours to know each other better, such a network could meet the basic human need of belonging to a group, while also taking advantage of the social influence between neighbours to increase the effectiveness of the energy feedback provided.

    This thesis sought to: 1) Identify needs of residents that could be served by a local social network and explore whether such a network could provide a beneficial context for energy feedback; 2) identify and evaluate a set of design principles for energy feedback and use them to propose a prototype feedback design suitable for use in a local social network; and 3) design and implement a baseline study for measuring changes in aspects of social and environmental sustainability in a neighbourhood that introduction of a local social network can achieve, such as social cohesion, trust, safety, and energy attitudes and behaviour.

    In order to achieve these objectives, the Research Through Design methodology was used. This resulted in mixed methods research using quantitative (household survey) and qualitative (focus group interviews, stakeholder consultation workshop) methods. The research was conducted in two eco-districts in Stockholm, Sweden: Hammarby Sjöstad and Stockholm Royal Seaport.

    Regarding the first objective, results from the household survey indicated a need for increased interaction between neighbours in Stockholm Royal Seaport, while the focus group discussions revealed local communication needs that a local social network could meet. However, the possibility to use social influence between neighbours in increasing the intention to save energy was shown to be rather weak, possibly because of the current low level of connection between neighbours. Regarding the second objective, a set of design principles was identified using a literature study. They were used to create a design prototype of energy feedback that was presented to potential end-users in a stakeholder consultation workshop and then refined using suggestions given in the workshop. The workshop indicated support for many of the design principles as they were indirectly mentioned in the discussions. The design principle of fair feedback was further explored, suggesting use of typical household consumption as part of a fair comparison metric and when setting reduction goals.

    Regarding the third objective, an evaluation method with baseline survey and follow-up surveys was suggested. The household survey served as a baseline for measuring social and environmental sustainability aspects in a neighbourhood. Further research is needed on the effectiveness of a local social network as an engagement mechanism for energy feedback.

    Designing energy feedback for a local social network2019In: Energy and Buildings, ISSN 0378-7788, E-ISSN 1872-6178, Vol. 199, p. 88-101Article in journal (Refereed)
    Abstract [en]

    Engaged households are needed for the future ‘smart grids’ to function, but it is difficult to engage residents in their household electricity consumption. Building on earlier research suggesting that a local social network could provide a suitable context for energy feedback, this paper examines how feedback presented in a social network should be designed in order to be better understood by the residents and encourage long-term engagement. A review of the literature on design principles and cases where they had been implemented identified 24 principles. A prototype feedback design adapted for a local social network was made, based on design principles deemed suitable for the screens designed. End-user feedback on the prototype was collected through a stakeholder consultation workshop. In the workshop dis- cussions, 17 identified principles were mentioned and there was support for 15 of these, one was both supported and contested and two were contested. Based on comments and suggestions from end-users, a revised version of the feedback prototype was made for implementation in a pilot study in Sweden and Portugal.

    Gossip-based partitioning and replication for Online Social Networks2014In: ASONAM 2014 - Proceedings of the 2014 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining, 2014, p. 33-42Conference paper (Refereed)
    Abstract [en]

    Online Social Networks (OSNs) have been gaining tremendous growth and popularity in the last decade, as they have been attracting billions of users from all over the world. Such networks generate petabytes of data from the social interactions among their users and create many management and scalability challenges. OSN users share common interests and exhibit strong community structures, which create complex dependability patterns within OSN data, thus, make it difficult to partition and distribute in a data center environment. Existing solutions, such as, distributed databases, key-value stores and auto scaling services use random partitioning to distribute the data across a cluster, which breaks existing dependencies of the OSN data and may generate huge inter-server traffic. Therefore, there is a need for intelligent data allocation strategy that can reduce the network cost for various OSN operations. In this paper, we present a gossip-based partitioning and replication scheme that efficiently splits OSN data and distributes the data across a cluster. We achieve fault tolerance and data locality, for one-hop neighbors, through replication. Our main contribution is a social graph placement strategy that divides the social graph into predefined size partitions and periodically updates the partitions to place socially connected users together. To evaluate our algorithm, we compare it with random partitioning and a state-of-the-art solution SPAR. Results show that our algorithm generates up to four times less replication overhead compared to random partitioning and half the replication overhead compared to SPAR.

    Travel information services and travel planning practice: Changing the horizon of assistanceIn: International Journal of Sustainable Transportation, ISSN 1556-8318, E-ISSN 1556-8334Article in journal (Other academic)
    Abstract [en]

    Recent decades have seen rapid growth in ICT services relating to transportation. Different types of travel information services have been proposed as a means to decrease the environmental impacts of transportation through behavioural change. However, empirical evidence shows that travel planning is a fragmented, distributed and fluid process that is not as enclosed in time and space or delimited in content, as existing ICT services for travel planning would imply, despite smart and mobile solutions. This paper examines the role of planning and coordination in the travel choices of everyday life and the time horizons and decisions that are part of current travel planning services. It also considers how travel information services of tomorrow, linked with other ICT services, could be designed to stretch the horizon of assistance, in order to better support travel planning processes in everyday life. Finally, it critically discusses the role of travel information services and ICT in the work of achieving more sustainable mobility.
