    Information requirements for national level cyber situational awareness2018In: Proceedings of the 2018 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining, ASONAM 2018, Institute of Electrical and Electronics Engineers Inc. , 2018, p. 774-781Conference paper (Refereed)
    Abstract [en]

    As modern societies become more dependent on IT services, the potential impact both of adversarial cyberattacks and non-adversarial service management mistakes grows. This calls for better cyber situational awareness-decision-makers need to know what is going on. The main focus of this paper is to examine the information elements that need to be collected and included in a common operational picture in order for stakeholders to acquire cyber situational awareness. This problem is addressed through a survey conducted among the participants of a national information assurance exercise conducted in Sweden. Most participants were government officials and employees of commercial companies that operate critical infrastructure. The results give insight into information elements that are perceived as useful, that can be contributed to and required from other organizations, which roles and stakeholders would benefit from certain information, and how the organizations work with creating cyber common operational pictures today. Among findings, it is noteworthy that adversarial behavior is not perceived as interesting, and that the respondents in general focus solely on their own organization.

    Design and use of mobile technology in distance language education: Matching learning practices with technologies-in-practice2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis focuses on the adaptation of formal education to people’s technology- use patterns, their technology-in-practice, where the ubiquitous use of mobile technologies is central. The research question is: How can language learning practices occuring in informal learning environments be effectively integrated with formal education through the use of mobile technology? The study investigates the technical, pedagogical, social and cultural challenges involved in a design science approach.

    The thesis consists of four studies. The first study systematises MALL (mobile-assisted language learning) research. The second investigates Swedish and Chinese students’ attitudes towards the use of mobile technology in education. The third examines students’ use of technology in an online language course, with a specific focus on their learning practices in informal learning contexts and their understanding of how this use guides their learning. Based on the findings, a specifically designed MALL application was built and used in two courses. Study four analyses the app use in terms of students’ perceived level of self-regulation and structuration.

    The studies show that technology itself plays a very important role in reshaping peoples’ attitudes and that new learning methods are coconstructed in a sociotechnical system. Technology’s influence on student practices is equally strong across borders. Students’ established technologies-in-practice guide the ways they approach learning. Hence, designing effective online distance education involves three interrelated elements: technology, information, and social arrangements. This thesis contributes to mobile learning research by offering empirically and theoretically grounded insights that shift the focus from technology design to design of information systems.

    Blended Language Learning: A Thematic Overview of the Most Highly Cited Research2018In: Blended Language Learning: International Perspectives on Innovative Practice / [ed] Dr. Agnieszka Palalas, China Central Radio & TV University Press Co. Ltd. , 2018Chapter in book (Refereed)
    Abstract [en]

    This chapter sets out to give an introduction to the blended language learning (BLL) research domain through an analysis of the most impactful BLL research as measured by Harzing’s Publish and Perish software. After an initial outline of the field of BLL and its development, the chapter discusses the research methods and approaches applied in the selected articles and demonstrates that a majority of the articles use a descriptive approach and the dominating method is interpretative studies. The chapter then goes on to analyse the themes of the articles and divides them in to six sections: students’ readiness for BLL, teachers’ perceptions of BLL, learner autonomy and self-regulated learning, second language acquisition, technology and BLL design. Finally, we offer future research directions in order to increase the sustainability of BLL, both as the field of practice and the research area. Overall the 41 reviewed studies present a substantial case for the benefits of BLL. However, to ensure the sustainability of BLL design and thus the generalisability of the research findings further BLL designers and researchers need to apply firm theories.

    Cross-cultural analysis of users’ attitudes toward the use of mobile devices in second and foreign language learning in higher education: A case from China and Sweden2013In: Computers and education, ISSN 0360-1315, E-ISSN 1873-782X, Vol. 69, p. 169-180Article in journal (Refereed)
    Abstract [en]

    The present study examined the current state of students’ attitudes toward mobile technology use in and for second and foreign language learning in higher education. Moreover, the study investigated if age, gender or cultural factors affect these attitudes. A total of 345 students from two in many aspects different countries, China (Yunnan University) and Sweden (Dalarna University) participated in this study. To access learners’ perceptions toward mobile technology use, we employed Kearney’s pedagogical framework to mobile learning from a socio-cultural perspective (Kearney, Schuck, Burden, & Aubusson, 2012). Hofstede’s cultural dimensions were used to approach students’ cultural views, as these dimensions represent some values – aspects of culture – that may affect attitudes toward technology and learning individually as well as in combination. The findings show the respondents’ attitudes toward mobile learning are very positive with individualization being most positive (83%) followed by collaboration (74%), and authenticity (73%). The statistical analysis indicates that Hofstede’s factors cannot explain the differences in mobile-assisted language learning (MALL) attitudes in the chosen sample. Among the personal factors, gender is identified to be a predictor to explain the differences in students’ attitudes toward MALL. This study shows that technology itself seems to be the most important culture-shaping factor, more important than culture inherited from the physical environment, and more important than age.

    Systematising the Field of Mobile Assisted Language Learning2013In: International Journal of Mobile and Blended Learning, ISSN 1941-8647, E-ISSN 1941-8655, Vol. 5, no 4, p. 72-90Article in journal (Refereed)
    Abstract [en]

     This study provides a systematic review of mobile assisted language (MALL) research within the specifc area of second language acquisition (SLA) during the period of 2005-2012 in terms of research approaches, theories and methods, technology, and the linguistic knowledge and skills' results. The fndings show a shift from the prevailing SMS-based language learning in 2005-2008 towards the use of more advanced multimedia and intelligent learning systems in the last years. Many highly cited studies focus on design of mobile language learning systems and experimental evaluation of their effectiveness. Studies often draw on mature pedagogic models and methods. However, descriptive and small-scale experimental studies dominate. In terms of theoretical approaches and frameworks, there is a lack of specifc reference to mobile learning conceptual and theoretical models, which makes it diffcult to distinguish any specifc mobile learning theories from other learning theories. Research has so far paid most attention to learners' vocabulary acquisition.

    Understanding students’ learning practices: challenges for design and integration of mobile technology into distance education2015In: Learning, Media & Technology, ISSN 1743-9884Article in journal (Refereed)
    Abstract [en]

    This study explores the design requirements for mobile applications for second language learning in online/distance higher education settings. We investigate how students use technology and how they perceive that these technologies-in-practice facilitate their language learning. Structuration Theory is used for the analysis. Results show that design needs to consider that (i) students use their private mobile technologies frequently when conducting self-initiated learning tasks, (ii) students’ mobile technologies-in-practice are important, and course designers should design materials and tools for such use practices, and (iii) students prefer to work on their own due to the limited time they want to devote to their learning. Consequently, in regard to the pervasive nature of mobile technology integration in society and into students’ habitual use, they need various software tools on such devices to support individual learning.

    Reducing Free Riding: CLASS–A System for Collaborative Learning Assessment2019In: Methodologies and Intelligent Systems for Technology Enhanced Learning, 9th International Conference, Workshops / [ed] Elvira PopescuAna Belén Gil, Loreto Lancia Luigia Simona Sica, Anna Mavroudi, Springer, 2019, Vol. 1008, p. 132-138Conference paper (Refereed)
    Abstract [en]

    In today’s era of digitalization of education, Computer Supported Collaborative Learning is becoming increasingly important in higher education. This type of learning has been frequently associated in the recent research literature with student regulation, feedback from peers and a student assessment schema which can incorporate both formative and summative assessment strategies. This work-in-progress paper presents the CLASS system which caters for all these aspects. Furthermore, the system supports mechanisms for the prevention of the free riding phenomenon, which has been reported in the literature as one of the most important disadvantages in group student work. The paper discusses the higher education context in which the CLASS system was developed and used, along with its design affordances and how these affordances can facilitate CSCL. The paper can be useful to designers and developers of CSCL systems as well as to practitioners that are interested in how they can exploit CSCL with their students working in groups.

    Branding through mobile applications: - A case study of Swedish campaign applications2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    We are a few years into a paradigm shift where mobile Internet usage around the world is increasing fast. Smartphones have in Sweden become the device a substantial proportion of the population have, and companies have seen them as a new way to communicate with consumers. This thesis is a case study of four smartphone applications issued by companies in brand building purposes. The applications are King of the slope by Vattenfall, Körklar? by SalusAnsvar, McWrap Go&Get by McDonalds and Många Sträckor Små by Lantmännen. Empirical materials are gathered through semi-structured interviews with people involved in the creation of each application. Results are then analysed based on what initial goals each issuer had set for the application with the aim of obtain learnings valuable to future application issuers. Findings have shown that the mindset when creating these applications has generally been short-term. This contradicts the nature of a mobile application and its purpose of strengthening a company’s brand, which usually is a long-term process. We advocate a more long-term mindset and a consumer-oriented standpoint instead of product- oriented when creating mobile applications for branding purposes.

    The Effects of National Culture Values on Consumer Acceptance of E-commerce: The Swedish Case2015Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    A large amount of research has been conducted in order to seek explanations that clarify e-commerce acceptance throughout the world; however, there is a gap in the research as to how e-commerce acceptance is attributable to national culture. Two previous studies (Yoon, 2009), (Capece, et al., 2013) used Hofstede’s five dimensions of national culture in conjunction with the Technology Acceptance Model (TAM) as a means to filling this gap with perspectives on low-acceptance populations (China in 2008 and Italy in 2013). The study presented in this paper is a continuation of the previous work, offering a perspective on a high-acceptance population (Sweden).

    The main research question is about investigating how Swedish e-commerce acceptance is related to national culture, and the answer is sought by probing on the Swedish perspective of e-commerce in the light of the TAM, e-commerce trust, and Hofstede’s five dimensions of national culture in an online survey. The data is analyzed using Structural Equation Modeling (SEM), and compared to the findings of the Chinese and Italian precursors. Furthermore, an attempt is made to explain the contrast between the comparably high e-commerce acceptance in Sweden to the lower degrees of acceptance in China and Italy.

    Personalintern Kommunikation: En kartläggning av formella och informella strukturer vid hematologisk slutenvård2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The recent technological development within information technology has affected the structure of organisations and the organisation of work. In health care, and for several reasons, the need for communication audits has thus been highlighted. Patient safety may be risked by mistakes linked to deficiencies in information transfer. Often are hierarchical structures, unclear roles and gaps in information flows suggested causes. On the other hand, the health care sector often is considered as one of society's most complex knowledge organizations, characterized by intense information flows with traits linked to strong professions.

    Communication audits are accomplished with the objective to identify causes of ineffective communication, lack of explicit communication processes, to suggest improvements and provide management and staff with more objective descriptions of roles and links. The research field has for a while been dominated by large-­‐scale surveys and resent studies has pointed at the need for studies of daily communication environments at site of organizations. This is such a study, carried through at a department for inpatient care at the University Hospital Karolinska, located in Huddinge, Stockholm. In 2012, the studied department relocated into new facilities and completed a small restructuring of its organization, affecting roles and channels of communication. The perception of the new organization was inefficiency, both in time and difficulties to overview the structure. The purpose of this thesis has therefore been to discuss and highlight how to clarify formal structure of the internal communication among staff based on parameters such as roles and channels of communication.

    The study maps today's formal structure, which is the expected exchange of information as described in job descriptions and work policies and compares this with developed informal structures based on how employees prefer to exchange information. A mix of data collection methods is used. An analysis is conducted were the organization's communication network as perceived as exchange of information between the employees is visualised. The results showed differences between the formal structure and the informal structure that could be used to highlight aspects of how the identified differences could be used to clarify the formal structure.

    The study points at six areas were the formal structure may be elucidated; more documented communicative responsibilities and procedures, a strengthening of communication within working groups rather than within professions, a definition of the chief physician and the assistant physicians' communicative roles, an increased continuity in key roles for communication, a review of the physical structure's impact on communication and finally, create conditions for fast communication with information technology.

    Abstract [en]

    With social media services becoming more and more popular, there now exists a constant stream of opinions publicly available on the Internet. In crisis situations, analysis of social media data can improve situation awareness and help authorities to provide better assistance to the affected population. The large amount of activity on social media services makes manual analysis infeasible. Thus, an automatic system that can assess the situation is desirable. In this paper we present the results of training machine learning classifiers to being able to label tweets with one of the sentiment labels positive, neutral, and negative. The classifiers were evaluated on a set of Russian tweets that were collected immediately after the much debated verdict in the 2012 trial against members of the Russian punk rock collective Pussy Riot. The aim for the classification process was to label the tweets in the dataset according to the author's sentiment towards the defendants in the trial. The results show that the obtained classifiers do not accurately and reliably classify individual tweets with sufficient certainty. However, the classifiers do show promising results on an aggregate level, performing significantly better than a majority class baseline classifier would.

    Using multi-level frontiers in DEA models to grade countries/territories2016In: Journal of Informetrics, ISSN 1751-1577, E-ISSN 1875-5879, Vol. 10, no 1, p. 238-253Article in journal (Refereed)
    Abstract [en]

    Several investigations to and approaches for categorizing academic journals/institutions/countries into different grades have been published in the past. To the best of our knowledge, most existing grading methods use either a weighted sum of quantitative indicators (including the case of one properly defined quantitative indicator) or quantified peer review results. Performance measurement is an important issue of concern for science and technology (S&T) management. In this paper we address this issue, leading to multi-level frontiers resulting from data envelopment analysis (DEA) models to grade selected countries/territories. We use research funding and researchers as input indicators, and take papers, citations and patents as output indicators. Our research results show that using DEA frontiers we can unite countries/territories by different grades. These grades reflect the corresponding countries' levels of performance with respect to multiple inputs and outputs. Furthermore, we use papers, citations and patents as single output (with research funding and researchers as inputs), respectively, to show country/territory grade changes. In order to increase the insight in this approach, we also incorporate a simple value judgment (that the number of citations is more important than the number of papers) as prior information into the DEA models to study the resulting changes of these Countries/Territories' performance grades.

    Emergence of a Digital Platform BasedDisruptive Mobile Payments Service2018In: International Journal of E-Business Research, ISSN 1548-1131, Vol. 14, no 3, p. 1-19Article in journal (Refereed)
    Abstract [en]

    Banks are motivated to be interested in developing platforms to provide mobile payment services to their customer and for those to be innovative. However, the successful implementation of a mobile payments service platform is mainly determined by how much players are fully motivated to realize it. In fact, in the Swedish context, the involvement level of mobile payment service platforms are very high whereas few studies have examined the related issues of mobile payments service platform. Thus, the purpose of this article is to investigate the factors leading banks to develop platforms and how banks manage these platforms. Data was collected by conducting interviews of applicable banks. The results mainly showed that the driving factors are significantly influenced by contextual factors, mutual objectives and opportunities. This article also looks forward to providing the payment industry with applicable guidelines for efficiently implementing and designing mobile payment service platforms.

    A comparison of citation disciplinary structure in science between the G7 countries and the BRICS countries2018In: Journal of Data and Information Science, ISSN 2096-157X, Vol. 3, no 3, p. 14-30Article in journal (Refereed)
    Abstract [en]

    This study aims to compare the characteristics of citation disciplinary structure between the G7 countries and the BRICS countries. In this contribution, which uses about 1 million Web of Science publications and two publications years (1993 and 2013), we compare the G7 countries and the BRICS countries with regard to this type of structure. For the publication year 2013, cosine similarity values regarding the citation disciplinary structures of these countries (and of nine other countries) were used as input to cluster analysis. We also obtained cosine similarity values for a given country and its citation disciplinary structures across the two publication years. Moreover, for the publication year 2013, the within-country Jeffreys-Matusita distance between publication and citation disciplinary structure was measured. First, the citation disciplinary structures of countries depend on multiple and complex factors. It is therefore difficult to completely explain the formation and change of the citation disciplinary structure of a country. This study suggests some possible causes, whereas detailed explanations might be given by future research. Second, the length of the citation window used in this study is three years. However, scientific disciplines differ in their citation practices. Comparison between citations across disciplines using the same citation window length may affect the citation discipline structure results for some countries. First, the results of this study are based on the WoS database. However, in this database some fields are covered to a greater extent than others, which may affect the results for the citation discipline structure for some studied countries. In future research, we might repeat this study using another database (like Scopus) and, in that case, we would like to make comparisons between the two outcomes. Second, the use of a constant journal set yielded that a large share of the journals covered by WoS year 2013 is ignored in the study. Thus, disciplinary structure is studied based on a quite restricted set of publications. The three mentioned limitations should be kept in mind when the results of this study are interpreted. Disciplinary structure on country level is a highlighted topic for the S&T policy makers, especially for those come from developing countries. This study observes the disciplinary structure in the view of academic impact, and the result will provide some evidence to make decision for the discipline strategy and funding allocation. Besides, Jeffreys-Matusita distance is introduced to measure the similarity of citation disciplinary structure and publication disciplinary structure. By applying this measure, some new observations were drawn, for example, "Based on the comparison of publication disciplinary structure and citation disciplinary structure, the paper finds most BRICS counties have less impact with more publications". The outcome of the cluster analysis indicates that the G7 countries and BRICS countries are quite heterogeneous regarding their citation disciplinary structure. For a majority of the G7 countries, the citation disciplinary structure tend to be more stable compared to BRICS countries with regard to the years 1993 and 2013. Most G7 countries, with United States as an exception, turned out to have lower values on the Jeffreys-Matusita distance than BRICS countries, indicating a higher degree of heterogeneity between the publication and the citation disciplinary structure for the latter countries. In other words, BRICS countries still receive much less citations in most disciplines than their publication output would suggest. G7 countries can still expect more citations than is to be expected based on their publication output, thereby generating relatively more impact than BRICS countries.

    Hacking for Sustainability2014Doctoral thesis, monograph (Other academic)
    Abstract [en]

    ICT for Sustainability is a growing research area looking at the potential of information and communication technologies for contributing to sustainability. The existing work in this area can be grouped in four main categories: The optimization of existing systems using ICT, the dematerialization of cultural assets and presence, the use of technology for behavioral change, and the support of sustainability practice and research. Within this research area, this thesis focuses on exploring how new technologies and approaches of working with data, such as APIs, mashups, crowdsourcing, open data, and dynamic visualizations, can be applied to sustainability and sustainability practice.

    This thesis follows a research through design method, where applications, prototypes, and events were created and released following an iterative design process. Five different design artifacts or “hacks” are presented and analyzed together as a portfolio. This collection of artifacts is a practical exploration of the research questions and it embodies the results.

    Based on the created artifacts, this text argues that the new technologies and paradigms coming from ICT can transform how sustainability work is performed, by changing the way that sustainability data is created, shared and visualized. This new “data-driven” approach is characterized by a bottom-up way of data gathering, automatic data collection and crowdsourcing, a real time orientation, a focus on transparency and openness, dynamic and interactive visualizations, and new approaches to innovation. These characteristics create new opportunities for making sustainability practice more effective and broaden its impact, but they also create new problems and increase existing risks.

    Finally it is argued that while information and communication technologies are usually treated as tools, these innovations in ICT for Sustainability are not only technological, but also cultural. The hacker ethic values connected with computer technologies, such as an open way of sharing knowledge, the focus on creativity as a driving force, and a hands-on approach, are key for understanding this research area and an important part of the contribution from ICT to sustainability.

    Hacking sustainability: Broadening participation through Green Hackathons2013Conference paper (Refereed)
    Abstract [en]

    Green Hackathon is an international series of coding events withsustainability purpose. Developers, researchers, environmental practitioners,and anyone else who is interested, work for a limited amount of time to createinnovative software solutions for sustainability. These events have explicitlyaimed to invite a broad spectrum of expertise besides technical expertise. Thisarticle presents the experiences and tensions of including these end users at amostly technically oriented event, and discusses how end-user developmentcould be used to encourage more reflective practices and as well as broadeningthe participation and the interdisciplinary collaboration in these events – withhigher-quality as a prospective outcome.

    Exploring REA and Open-edi business frameworks for service modeling2010In: CEUR Workshop Proceedings, 2010, p. 106-119Conference paper (Refereed)
    Abstract [en]

    Contemporary business collaborations foster enterprises to make their offerings available to partners and consumers as e-services. In this setting, high-level enterprise models, such as business models, provide an economically aware perspective for elicitation of business services, and thereby, e-services. Recently, REA and Open-edi business frameworks have been jointly considered to provide the Open-edi Business Transaction Ontology (OeBTO) for exploring concepts, relationships and actors involved in business collaborations. In this study, we use these frameworks and supporting architectures to propose a service-centric business model. From a model-based development perspective, the model that we propose is intended to be transformed to a system-centric service model, and further to Web service specifications and coordinations. The purpose of this study is primarily aimed toward an explorative and business-founded identification of services. An example from the insurance business sector is used to argument the way we ground and apply our proposed method.

    Understanding readers: Conducting sentiment analysis of instagram captions2018In: PROCEEDINGS OF 2018 THE 2ND INTERNATIONAL CONFERENCE ON COMPUTER SCIENCE AND ARTIFICIAL INTELLIGENCE (CSAI 2018) / 2018 THE 10TH INTERNATIONAL CONFERENCE ON INFORMATION AND MULTIMEDIA TECHNOLOGY (ICIMT 2018), Association for Computing Machinery (ACM), 2018, p. 33-40Conference paper (Refereed)
    Abstract [en]

    The advent of media transition highlights the importance of user-generated content on social media. Amongst the methods of analysis of user-generated content, sentiment analysis is widely used. Nevertheless, few studies use sentiment analysis to investigate user-generated content on Instagram in the context of public libraries. Therefore, this study aims to fill this research gap by conducting sentiment analysis of two million captions on Instagram. Supervised machine learning algorithms were employed to create the classifier. Three opinion polarities and six emotions were ultimately identified via these captions. These polarities provide new insights for understanding readers, thus helping libraries to deliver better services.

    Digitizing Health Care Welfare technology as a way to meet digital and demographic challenges in Sweden2017In: 2017 4th International Conference on Systems And Informatics (ICSAI), Institute of Electrical and Electronics Engineers (IEEE), 2017, p. 78-83Conference paper (Refereed)
    Abstract [en]

    Digitizing health care takes place in parallel with demographic changes posing one of the greatest social changes of our time. Although modern elderly care has evolved closely related to technological development and evaluated by established methods, digitization places new demands on approaches as a result of its systemic characteristics and its potential to bridge different environments and social contexts and the involvement of elderly users. This paper is paying attention to three challenges: digitizing already existing technological environments; implementing technology in new arenas outside hospitals and laboratories; and the imbalance between perceptions of elderly users and their actual needs and demands. The conclusions point out that digitization provides opportunities to deepen or reflections on technology and implementation, develop multidisciplinary collaborations and enhance proactive engagements to make new technologies work.
