    Information Technology Governance: The Role of Organizational Culture and Structure2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Information Technology Governance (ITG) is among the most important challenges for the managers today. IT is not anymore just a supportive tool but also a strategic driver for the businesses. In the dynamic and competitive world of today, it is crucial for organizations to know how to govern IT rather than just to use it. IT governance deals with specifying responsibilities and decision rights to encourage the desirable behaviour from IT and generate value from IT investments. IT governance can impact the overall performance of organizations, however there are still difficulties in understanding IT governance and the factors that may influence it.

    Organizational culture and structure are among the factors that have significant influence on many issues in an organization. According to previous research, organizational culture and structure need to be considered when implementing IT governance. However, there is a lack of research focusing on how organizational culture and structure can influence IT governance performance and implementation. Thus, the main research question addressed in this thesis is: How are organizational culture and structure related to IT governance? To address this question, this research has performed literature reviews and conducted case studies to investigate the role of organizational culture and structure on IT governance. As the first step, the previous literature was reviewed to find the gaps in the research on culture and IT governance. As the next step, four case studies were conducted to explore the influence of organizational culture and structure on IT governance. Two case studies have investigated the relation between organizational structure and IT governance implementation and performance in large organizations; and two other case studies investigated on how different types of organizational culture influence IT governance performance outcomes.

    The results of this research respond to the research question by specifying the role of culture in IT governance through a categorization of prior research both from research and practice perspectives; specifying the influence of different organizational culture types on IT governance performance outcomes in different organizations; and by specifying IT organizational structure relationship with IT governance performance outcomes and IT governance implementation.

    The research presented in this thesis provides both theoretical and empirical contributions to the IT governance research and practice.

    The Influence of Cloud Computing on IT Governance in a Swedish Municipality2020In: Information Systems: 17th European, Mediterranean, and Middle Eastern Conference, EMCIS 2020, Dubai, United Arab Emirates, November 25–26, 2020, Proceedings / [ed] Marinos Themistocleous, Maria Papadaki, Muhammad Mustafa Kamal, Springer, 2020, p. 623-639Conference paper (Refereed)
    Abstract [en]

    Cloud computing is used to a greater extent in today’s organizations and enables organizations to obtain on-demand network access to IT services. When cloud computing is adopted in an organization, the IT governance becomes more challenging, because organizations need to address business and IT-related processes as well as managing risks and maintaining the relationship with cloud computing vendors. This research aims at finding how cloud computing service model specifically Software as a Service (SaaS) influence IT governance structures, processes and relational mechanisms in a public organization. For this purpose a case study was conducted in a Swedish municipality and the data was collected through interviews with IT managers and from internal documents of municipality and was analyzed using thematic analysis. The results of this study shows that SaaS influences the IT governance structure by improving roles and responsibilities definition and speeds up the decision-making processes. Moreover, the communication with the vendors is more efficient due to the use of SaaS.

    Facing The Digitalization Challenge: Why Organizational Culture Matters and How It Influences IT Governance Performance2017In: Information Systems Development: Advances in Methods, Tools and Management: Proceedings / [ed] N.

    Abstract [en]

    Today it is not possible for the companies to compete without having IT as a strategic driver. That is why IT governance becomes crucial for managers to bring the most value from IT to the business. Additionally organizational culture is an important factor and often blamed when IT governance projects fail. However little in-depth research investigated how the organizational culture changes can improve the IT governance performance. This research is a case study of the IT department of a large company attempting to improve the IT governance while facing the digitalization challenge. In this case the IT department has an organizational culture change journey seeking to improve the IT governance performance. The results indicate that the initial clan culture orientation of the IT department has led to a successful IT governance performance in cost-effective use of IT. Furthermore, adhocracy is identified as preferred culture for improving IT governance for growth.

    Abstract [en]

    Managers face enormous challenges today to plan the decision rights and responsibilities in order to reach desired IT behaviors which are aligned with business objectives of organizations. This is known as IT governance and is ranked as one of the firms' top concerns. Not surprisingly, it is crucial for organizations to find the affecting factors on IT governance and solve the problems associated with it. Culture in national, organizational or group level is an affecting factor in organizations that can play a role in IT governance and this role is rarely explored in academic research. This paper provides a literature review investigating the influence of culture on IT governance. The research purpose is to identify how culture and IT governance in the companies can be linked together and promote this area for future research. The literature review is done systematically and the findings are classified by using an IT governance framework with three main components of structures, processes and relational mechanisms. The results indicate there is an influence from national and organizational culture on IT governance. However, the number of studies is very few and there is still a lack of knowledge on how culture can influence IT governance. This research calls upon a further research on culture impact on achieving an effective IT governance implementation in organizations.

    Abstract [en]

    IT governance is crucial for managers to regulate the decision rights and responsibilities that the desired IT behaviors and business objectives are aligned with each other. Additionally, culture in national, organizational or group level can play a role in IT governance and this role is rarely explored in academic research. This paper provides a literature review investigating the impact of culture on IT governance. It is aimed to find the linkage between these two concepts and to promote this area for future research. The literature review was done systematically and the findings are categorized by using an IT governance framework which includes three main components: structures, processes and relational mechanisms. The results indicate there is an influence from national and organizational culture on IT governance, especially on relational mechanisms. However, the number of studies is very few and there is still a lack of knowledge on how culture can influence IT governance.

    Abstract [en]

    IT governance is one of the top concerns of organizations today seeking to gain value from their IT investments and create competitive advantage. Organizational culture on the other hand is one of the various factors influencing IT governance performance. However there is not much research conducted to understand this topic deeply. This research thus, is exploring the influence of organizational culture on four IT governance performance outcomes through a case study in IT department of a large Swedish company. The results provide evidence that organizational culture is influencing IT governance performance. Specifically the current clan culture orientation of the IT department has led to a successful IT governance performance in cost-effective use of IT. Furthermore adhocracy as the preferred culture is identified to influence IT governance in effective use of IT for growth which is not so successful with the current clan culture.

    IT Organizational Structure Relationship with IT Governance Performance: Case of a Public Organization2017In: Information Technology Governance in Public Organizations: Theory and Practice / [ed] Lazar Rusu, Gianluigi Viscusi, Cham, Switzerland: Springer, 2017, no 0, p. 229-252Chapter in book (Refereed)
    Abstract [en]

    Information Technology (IT) is widely used in organizations and managers continue to struggle with how to govern IT. IT governance concerns the decision rights and division of responsibilities to achieve value from IT investments. Any IT governance approach is incorporated into a given organizational structure. However in the particular context of public organizations, there is little research on IT organizational structure relationship with IT governance performance. In this research, a case study is done in a public organization to find out how suitable is the organizational structure of the IT department is in relation with the IT governance performance. The results reveal that the IT department organizational structure needs to suit the IT governance performance desired outcomes. In this case, operating as a public organization has actuated the organization to focus on IT governance outcome of effective use of IT for growth. This together with the IT governance archetypes of this public organization for different IT decisions led the IT department leaders to adopt a matrix organizational structure.

    Abstract [en]

    In today's complex organizations, IT governance is an important managerial challenge. IT governance deals with decisions and responsibilities concerning IT. There are many factors influencing IT governance. One factor that has remained relatively unexplored by academic research is that of organizational culture. This research explores the influence of the organizational culture of collaborative networks on IT governance performance. A case study was conducted in a large complex company with several networks. The findings indicated that the networks desire different organizational culture types based on their priorities for IT governance outcomes. A clan organizational culture is desired when aiming for effective use of IT for asset utilization and cost effective use of IT. An adhocracy culture is desired when prioritizing the effective use of IT for business growth. Finally a combination of market and hierarchy organizational culture is desired when seeking effective use of IT for business flexibility and cost cutting.

    Digital Transformation Success Through Aligning the Organizational Structure: Case Study of Swedish Public Organizations2022In: AMCIS 2022 Proceedings, Association for Information Systems (AIS) , 2022Conference paper (Refereed)
    Abstract [en]

    A Digital Transformation fundamentally involves the implementation of one or more digital tools, which is a process often burdened with challenges. It is estimated that approximately 66 to 84 percent of the taken Digital Transformation initiatives are unsuccessful, which can be attributed to organizational shortcomings, more specifically structural ones. While public organizations regularly do not achieve the same success as those in the private sector, it was of interest to investigate the Swedish ones. Where 86 percent of residents use the internet to interact with public authorities. Previous research has singled out the IT organization to be the appointed leader of Digital Transformations, further research on that relationship is limited. Therefore, this study examines how the IT organization, in an agile environment, can align its structure for a successful Digital Transformation. To answer the discovered research problem, the following research question has been formulated: “How should an IT organization’s structure be aligned in an agile environment in order to achieve a successful Digital Transformation?”. This is research in progress and will be continued by conducting case studies in four public organizations. Data will be collected through semi0structured interviews and analyzed thematically. Finally, a presentation of different aspect of organizational structure alignment through digital transformation based on these cases will be provided.

    Organizational Aspects in Achieving a Successful Digital Transformation: Case of an ERP System Change2022In: Information Systems: 18th European, Mediterranean, and Middle Eastern Conference, EMCIS 2021, Virtual Event, December 8–9, 2021, Proceedings / [ed] Marinos Themistocleous; Maria Papadaki, Springer, 2022, p. 653-666Conference paper (Refereed)
    Abstract [en]

    Digital transformation has been an interesting concept from the organizational perspective for a long time. The benefits of a successful digital transformation can take your organization into the next step by providing an increased organizational growth, aid market reachability by penetrating new and exciting markets, or enable your business operations to function to a greater extent than before with higher efficiency and lower lead times. Digital transformation is however a complex and diverse concept that means to integrate new innovations by using digital technology into the organization with the need of making greater organizational changes to succeed. This research, has explored how different organizational aspects like structural, technological and cultural ones can impact the success of a digital transformation during an ERP system change. A case study has been conducted in a company to identify how the current structural, technological, and cultural aspects influence the current digital transformation in that the company. The data was collected through interviews with employees having managerial roles and from internal documents of company and was analyzed using thematic analysis. The results show an agile approach, a more decentralized structure and high readiness for change, along with a transparent communication between management and co-workers to be beneficial for a successfully digital transformation.

    Abstract [en]

    The paper addresses three main problems resulting from uncertainty in information security management: i)dynamically changing security requirements of an organization ii) externalities caused by a security system and iii)obsolete evaluation of security concerns. A framework based on options reasoning borrowed from corporate finance is proposed and adapted to evaluation of security architecture and decision-making for handling these issues at organizational level. The adaptation as methodology is demonstrated by a large case study validating its efficacy.

    Abstract [en]

    Information technology evolves at a faster pace giving organizations a limited scope to comprehend and effectively react to steady flux nature of its progress. Consequently the rapid technological progression raises various concerns for the IT system of an organization i.e. existing hardware/software obsoleteness, uncertain system behavior, interoperability of various components/method, sudden changes in IT security requirements and expiration of security evaluations. These issues are continuous and critical in their nature that create uncertainty in IT infrastructure and threaten the IT security measures of an organization. In this research, Options theory is devised to address uncertainty issues in IT security management and the concepts have been developed/validated through real cases on SHS (Spridnings-och-Hämtningssystem) and ESAM (E-society) systems. AUMSIS (Automated Uncertainty Management System in Information Security) is the ultimate objective of this research which provides an automated system for uncertainty management in information security. The paper presents the architectural description of AUMSIS, its various components, information flow, storage and information processing details using options valuation techniques. It also presents heterogeneous information retrieval problems and their solution. The architecture is validated with examples from SHS system

    Modelling Health Information during Catastrophic Events - A Disaster Management System for Sudan2017In: IST-Africa 2017: Conference Proceedings / [ed] Paul Cunningham, Miriam Cunningham, International Information Management Corporation Limited, 2017, p. 1-9Conference paper (Refereed)
    Abstract [en]

    There is an increasing trend of disastrous events during past decade with significant damage in terms of lives, infrastructure, economics and environment. Disastrous events are affecting communities worldwide and, apart for the actual and personal suffering involved, can fundamentally disrupt societal functions for many years. This is particularly the case in already vulnerable regions, which often require external assistance of various kinds. In order to reduce catastrophic effects of disasters, disaster mitigation measures and crisis reduction must be systematically planned and managed. This includes correct damage assessment, fast, efficient and prepared responses, adequate resource allocation and organisation of the relief processes. Obviously, the conditions and abilities to implement such measures are very different in various locations, where regions have particularly severe conditions. In this paper, we discuss crisis management in Sudan and highlight the need for national and regional disaster management processes and activities as well as general framework for the design of an efficient disaster management program in Sudan.

    Application of a structured decision-making process in cryospheric hazard planning: Case study of Bering Glacier surges on local state planning in Alaska2024In: Journal of Multi-Criteria Decision Analysis, ISSN 1057-9214, E-ISSN 1099-1360, Vol. 31, no 1-2, article id e1825Article in journal (Refereed)
    Abstract [en]

    Surging glaciers are glaciers that experience rapidly accelerated glacier flow over a comparatively short period of time. Though relatively rare worldwide, Alaska is home to the largest number of surge-type glaciers globally. However, their impact on the broader socioecological system in the state is both poorly understood and under-researched, which poses a challenge in developing appropriate sustainability decisions in Alaska. We investigated how the surge patterns of the Bering Glacier in Alaska have potentially devastating effects on the local ecological biodiversity of its watershed via a structured decision-making analysis of the different possible consequences. Specifically, this analysis was conducted to explore the various outcomes of a Bering Glacier surge particularly if humans have an increased presence near the glacier due to the area potentially becoming a state park. This work explored the benefits of applying a risk and decision analytical framework in a cryosphere context, to better understand the socioeconomic impact of glacier surges. This is a novel approach in which a decision analysis tool was used to better understand an environmental sustainability challenge, offering an innovative method to support the achievement of the United Nations Sustainability Development Goals in Alaska. We therefore emphasise the need for integrated biophysical and socioeconomic analyses when it comes to understanding glacier hazards. Our research highlights the importance of understanding and researching biophysical changes as well as using a structured decision-making process for complicated hazard planning scenarios, exemplified via glaciated regions in Alaska, in order to create adaptation strategies that are sustainable and encompass the range of possible outcomes.

    Tweens negotiating identity online – Swedish girls' and boys' reflections on online experiences2013In: Journal of Youth Studies, ISSN 1367-6261, E-ISSN 1469-9680, Vol. 16, no 8, p. 951-969Article in journal (Refereed)
    Abstract [en]

    How do Swedish tweens (10–14 years old) understand and experience the writing of their online identities? How are such intertwined identity markers as gender and age expressed and negotiated? To find some answers to these questions, participants in this study were asked to write a story about the use of online web communities on pre-prepared paper roundels with buzzwords in the margins to inspire them. Content analysis of these texts using the constant comparative method showed that the main factors determining how online communities are understood and used are the cultural age and gender of the user. Both girls and boys chat online, but girls more often create blogs while boys more often play games. Gender was increasingly emphasised with age; but whereas boys aged 14 described themselves as sexually active and even users of pornography, girls of the same age described themselves as shocked and repelled by pornography and fearful of sexual threats. In this investigation an intersectionalist frame of reference is used to elucidate the intertwined power differentials and identity markers of the users' peer group situation.

    ICT-based trade facilitation and the MDGs: a case study of a public–private partnership in Ghana2014In: ICTs and the Millennium Development Goals: a United Nations Perspective, Springer, 2014, no 2013, p. 223-235Chapter in book (Other academic)
    Abstract [en]

    The strategic and innovative deployment and use of information and communication technologies (ICT) is important to development and the attainment of the millennium development goals (MDGs). Previous studies have suggested that ICT-based trade facilitation promotes development through better integration into global markets. Through an interpretive case study, this chapter explores an ICTbased initiative to connect members of the trading community in Ghana on an electronic data interchange (EDI) platform. More specifi cally, it explored the contributions of the initiative to effi cient trade facilitation and discusses the broader mplications for achieving the MDGs in Ghana. The research confi rms that the initiative has improved operational effi ciency at Ghana’s ports and borders. Furthermore, it has enabled effi cient and reliable collection of duties and taxes. The findings reinforce the view that government support and private sector expertise and funding are important factors in ICT-based e-government solutions in developing countries. The chapter contends that ICT-based trade facilitation can make a significant contribution to the attainment of the MDGs in Ghana.

    IT Governance Practices in a Public Organization in Ghana2014In: International Journal of Innovation in the Digital Economy, ISSN 1947-8305, E-ISSN 1947-8313, Vol. 5, no 2, p. 14-23Article in journal (Refereed)
    Abstract [en]

    The strategic importance of information technology (IT) in today's organizations and dependence on IT to support e-government strategies has increased the interest in IT Governance (ITG) in public sector organizations. From this perspective, this paper examines ITG practices in a public organization in Ghana (that has a responsibility to mobilize revenue for national development) in order to gain an insight into IT governance structures, processes and relational mechanisms and understand how this contributes to adding value through IT. The findings have revealed that this public organization has a centralized approach to IT governance, with inadequate board involvement concerning how IT investments can bring value and improve organizational performance. Furthermore, there are no IT steering and strategy committees to oversee IT governance as best practice requires.

    Abstract [en]

    In the information age, no organization can thrive without harnessing the power of IT. The effective deployment of IT to achieve business goals and gain competitive advantage requires the alignment of business and IT strategies of organizations. Using the Strategic Alignment Maturity model, this paper evaluates strategic alignment maturity of Customs Excise Preventive service, a frontline public organization charged with trade facilitation in Ghana. Strategic alignment maturity is at level 3; which implies the existence of an established process to leverage IT for efficiency and effectiveness. Efforts are required to strengthen alignment and fully harness the potential of IT to facilitate trade in Ghana.

    Informative Feedback and Explainable AI-Based Recommendations to Support Students' Self-regulation2024In: Technology, Knowledge and Learning, ISSN 2211-1662, E-ISSN 2211-1670, Vol. 29, no 1, p. 331-354Article in journal (Refereed)
    Abstract [en]

    Self-regulated learning is an essential skill that can help students plan, monitor, and reflect on their learning in order to achieve their learning goals. However, in situations where there is a lack of effective feedback and recommendations, it becomes challenging for students to self-regulate their learning. In this paper, we propose an explainable AI-based approach to provide automatic and intelligent feedback and recommendations that can support the self-regulation of students' learning in a data-driven manner, with the aim of improving their performance on their courses. Prior studies have predicted students' performance and have used these predicted outcomes as feedback, without explaining the reasons behind the predictions. Our proposed approach is based on an algorithm that explains the root causes behind a decline in student performance, and generates data-driven recommendations for taking appropriate actions. The proposed approach was implemented in the form of a dashboard to support self-regulation by students on a university course, and was evaluated to determine its effects on the students' academic performance. The results revealed that the dashboard significantly enhanced students' learning achievements and improved their self-regulated learning skills. Furthermore, it was found that the recommendations generated by the proposed approach positively affected students' performance and assisted them in self-regulation

    IT-supported Knowledge Repositories: Increasing their Usefulness by Supporting Knowledge Capture2008Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Organizations use various resources to achieve business objectives, and for financial gain. In modern business, knowledge is a critical resource, and organizations cannot afford not to manage it. Knowledge Management (KM) aims to support learning and to create value for the organization. Based on three levels of inquiry (why, what, how), work presented in this thesis includes a synthesized view of the existing body of knowledge concerning KM and hence a holistic characterization of KM. This characterization reveals a strong dependency between KM and Learning Organization (LO). Neither of them can be successful without the other. We show that a KM project resulting in an IT-supported knowledge repository is a suitable way to start when the intention is to initiate KM work. Thus, our research focuses on ITsupported knowledge repositories.

    Large numbers of KM projects fail, and organizations lack support for their KM undertakings. These are the main problems that our research addresses. In order for an IT-supported knowledge repository to be successful, it must be used. Thus, the content of the repository is critical for success. Our work reveals that the process of capturing new knowledge is critical if the knowledge repository is to include relevant and updated knowledge. With the purpose of supporting the capture process, this thesis provides a detailed characterization of the capture process as well as guidance aiming to facilitate the implementation of the capture process in such a way that knowledge is continuously captured, also after the KM implementation project is completed. We argue that the continuous capture of new knowledge which can potentially be stored in the knowledge repository will, in the long term perspective, have a positive influence on the usefulness of the repository. This will most likely increase the number of users of the repository and accordingly increase the number of successful KM projects.

    All the work presented in this thesis is the result of a qualitative research process comprising a literature review and an empirical study that were carried out in parallel. The empirical study is a case study inspired by action research, which involved participation in the project Efficient Knowledge Management and Learning in Knowledge Intensive Organizations (EKLär).

    Finding potential problems in the thesis process in higher education: Analysis of e-mails to develop a support system2015In: Education and Information Technologies: Official Journal of the IFIP technical committee on Education, ISSN 1360-2357, E-ISSN 1573-7608, Vol. 20, no 1, p. 21-36Article in journal (Refereed)
    Abstract [en]

    Autonomous learning hype has created much speculation in educational systems regarding how to develop the learning process. Final project (thesis) in Bachelor’s and Master’s levels is a significant part of study for students in higher education. However, there are some problems, which lead students not managing to do or finish their thesis. As a part of a solution to these problems, the Department of Computer and Systems Sciences (DSV) at Stockholm University, Sweden, has established an information and communication platform, called SciPro. The system was initiated in 2011 to support students and supervisors during the thesis process courses. This study contributes by exploring problems that learners have faced during the final project courses and analyzing discussed issues in the emails, sent to the SciPro support group, ThesisSupport. A random sample of one hundred emails has been analyzed with the help of a content analysis tool, in order to develop the categories, which cover the discussed issues. The result of the study shows six exhaustive and mutually exclusive categories of problems: 1) Thesis initiation (26 %), 2) Info-mail (4.7 %), 3) Technical issues (17.1 %), 4) Exemption (18.7 %), 5) Supervision (17.1 %), 6) Final seminar (16.4 %). Consequently, based on the significance of the categories, two groups of strategic suggestions are developed: 1) developing communications and 2) developing instructions. These strategies intend to enhance support for the autonomous learning process for the thesis courses in higher education.

    Learners’ Perceptions on the Structure and Usefulness of e-Resources for the Thesis Courses2014In: European Journal of Open, Distance and E-Learning, E-ISSN 1027-5207, Vol. 17, no 1, p. 154-171Article in journal (Refereed)
    Abstract [en]

    Nowadays, utility of information and communication technology (ICT) in education is a way to facilitate interaction and accessing information for learning in higher education. However, finding a set of structured e-resources to facilitate learning within specific courses is still a big challenge in most of the institutions and universities. This includes the problems and challenges for the thesis courses in both undergraduate (Bachelor) and graduate (Master) level in Sweden. To overcome or reduce the problems and enhance quality of outcomes in the thesis courses, the department of Computer and Systems Sciences (DSV) at Stockholm University has developed a Learning Support System, SciPro (Scientific Process), to support thesis process. This study aims at investigating learners’ perspectives on usefulness of structured e-resources in order to reduce challenges for finding information related to the thesis steps in SciPro. This is done based on an open online survey, carried out in 2012-2013 of students’ perspectives at DSV. The study found the actual problems and hence suggested a model as a way forward to sort the useful e-resources to support reducing the problems in the thesis process.

    Interaction Gaps in PhD Education and ICT as a Way Forward: Results from a Study in Sweden2016In: International Review of Research in Open and Distance Learning, E-ISSN 1492-3831, Vol. 17, no 3, p. 360-383Article in journal (Refereed)
    Abstract [en]

    Many research studies have highlighted the low completion rate and slow progress in PhD education. Universities strive to improve throughput and quality in their PhD education programs. In this study, the perceived problems of PhD education are investigated from PhD students' points of view, and how an Information and Communication Technology Support System (ICTSS) may alleviate these problems. Data were collected through an online open questionnaire sent to the PhD students at the Department of (the institution's name has been removed during the double-blind review) with a 59% response rate. The results revealed a number of problems in the PhD education and highlighted how online technology can support PhD education and facilitate interaction and communication, affect the PhD students' satisfaction, and have positive impacts on PhD students' stress. A system was prototyped, in order to facilitate different types of online interaction through accessing a set of online and structured resources and specific communication channels. Although the number of informants was not large, the result of the study provided some rudimentary ideas that refer to interaction problems and how an online ICTSS may facilitate PhD education by providing distance and collaborative learning, and PhD students' self-managed communication.

    Students’ Perspectives on Utility of Mobile Applications in Higher Education2013In: Trends in Mobile Web Information Systems: Revised Selected Papers / [ed] Maristella Matera, Gustavo Rossi, Springer, 2013, p. 44-56Conference paper (Refereed)
    Abstract [en]

    Use of Information and Communication Technologies (ICT) in pedagogy and learning in higher education supports the concept of Technology Enhanced Learning (TEL). Mobile devices and applications with educational purposes are part of using online ICT and facilitate autonomous learning in education. Using mobile applications for education has significantly improved in the last few years. However, there is still a gap, in which this concept is still not widely known and frequently experienced by learners. As a part of supporting TEL in higher education and filling this gap, the department of Computer and System Sciences at Stockholm University in Sweden is planning to develop a mobile application for the SciPro system. SciPro is the computer-mediated communication platform to support enhancement of thesis quality and facilitate autonomous learning in higher education, at both Bachelor and Master levels. This study aims to investigate and evaluate learners’ perspectives about utility of mobile applications in higher education and specifically to support SciPro functionalities. Almost 95% of the respondents use mobile applications for higher education and believe in the utility of mobile applications for supporting learning in higher education. This is while there are a few respondents (less than 5%), who do not fully share this opinion. More than 70% of the respondents think that a SciPro mobile application will add value to their thesis process. Even though it may not directly affect the speed and quality of the thesis, it will increase mobility, availability, and flexibility of accessing information and resources in SciPro.

    Abstract [en]

    The low completion rate and slow progress in PhD education have been highlighted in many studies. However, the interaction problems and communication gaps that PhD students encounter make this attempt even more challenging. The aim of this study is to investigate the peer interaction problems and ICT based solutions from PhD students’ perspectives. The data collection method was an online questionnaire and in-depth interviews were used to follow up. The target group for the survey was the PhD students in Computer Science at Stockholm University. The total number of respondents for the survey was 53 PhD students and eleven randomly selected PhD students for the interviews. The results reflected a lack of peer interaction as an important issue in the perspective of the students. Based on this, the study showed several ICT solutions that have the potential to reduce the interaction problems and thereby improve PhD students’ collaborative learning and research quality.

    Using text prediction for facilitating input and improving readability of clinical text2013In: MedInfo 2013: Proceedings of the 14th World Congress on Medical and Health Informatics / [ed] Christoph Ulrich Lehmann, Elske Ammenwerth, Christian Nøhr, IOS Press, 2013, p. 1149-1149Conference paper (Refereed)
    Abstract [en]

    Text prediction has the potential for facilitating and speeding up the documentation work within health care, making it possible for health personnel to allocate less time to documentation and more time to patient care. It also offers a way to produce clinical text with fewer misspellings and abbreviations, increasing readability. We have explored how text prediction can be used for input of clinical text, and how the specific challenges of text prediction in this domain can be addressed. A text prediction prototype was constructed using data from a medical journal and from medical terminologies. This prototype achieved keystroke savings of 26% when evaluated on texts mimicking authentic clinical text. The results are encouraging, indicating that there are feasible methods for text prediction in the clinical domain.

    Medical vocabulary mining using distributional semantics on Japanese patient blogs2014In: Proceedings of the 6th International Symposium on Semantic Mining in Biomedicine, 2014, p. 57-62Conference paper (Refereed)
    Abstract [en]

    Random indexing has previously been successfully used for medical vocabulary expansion for Germanic languages. In this study, we used this approach to ex- tract medical terms from a Japanese pa- tient blog corpus. The corpus was seg- mented into semantic units by a semantic role labeller, and different pre-processing and parameter settings were then evalu- ated. The evaluation showed that simi- lar settings are suitable for Japanese as for previously explored Germanic languages, and that distributional semantics is equally useful for semi-automatic expansion of Japanese medical vocabularies as for med- ical vocabularies in Germanic languages.

Although teachers should formally work with programming teaching from the autumn of 2018, programming has been taught in primary school for several years. While there is some research on younger students, most of the research has almost exclusively focused on didactic approaches and strategies used by teachers, educational values and practices that accompany programming teaching, and views of teachers regarding programming teaching. What is still missing is research that highlights how younger students experience these new practices and how they primarily perceive programming in traditional school subjects, such as mathematics. Thus, this paper reports on a thematic analysis of younger students' (n=44) perceptions of programming; students who have been introduced to and been taught programming in mathematics in grade 5.

    Didactic methods of integrating Programming in Mathematics in primary school: findings from a national project in Sweden2020In: SIGCSE '20: Proceedings of the 51st ACM Technical Symposium on Computer Science Education, Association for Computing Machinery (ACM), 2020, p. 261-267Conference paper (Refereed)
    Abstract [en]

    The association between mathematics and programming in an educational context is not new. Today, programming has been introduced into curricula worldwide for younger children. In the Swedish case, primary school teachers are expected to integrate programming in mathematics education from autumn 2018. However, Swedish teachers' knowledge of programming and programming didactics is limited. Meanwhile, there is little research on K-9 programming education. This has led to the dilemma that the mathematics teachers have limited support in didactic knowledge and good examples. This study reports on a teacher professional development project in programming. More specifically, teachers used Lesson Study to plan, execute, and evaluate lessons that integrated programming into various school subjects in elementary school. This study analyzed the didactic strategies developed in 10 lesson studies, as well as mapped the opportunities and challenges of pupils' learning in the mathematics subject. The result was the identification of three didactic strategies, which were analog programming, robot programming and block programming, as well as 11 didactic methods applied within these strategies. The paper contributes with examples of the didactic methods that teachers have developed and evaluated using lesson study. The paper further provides insights on how teachers can take progression into account by applying the three didactic strategies. At last but not least, the study shows a great need for teachers to develop computational thinking abilities.

    Strategic Planning of Knowledge Management Systems: A Problem Exploration Approach2007Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Knowledge management (KM) is focused on the problems and opportunities of using organizational knowledge as a resource. Information systems that are used to support KM processes are called knowledge management systems (KMS). A KMS is distinguished from any information system by the organizational processes that it supports, that is, creation, capture, storage and dissemination of competences and knowledge. The research area can be summarized as: “Perspectives and frameworks for the strategic planning of knowledge management systems, i.e. information systems for the support of organizational knowledge processes”. We approach the problem area from a strategic point of view, assuming that the problems of the area are based on a socio-technical dimension and that a multiple-paradigm approach is necessary for dealing with the problems of the various KM areas. The research strategy applied to achieve this is interpretative case studies. A number of case studies are used for exploring KM planning areas, developing frameworks for planning and testing the resulting approach. The empirical material consists of three main case studies, together with a number of secondary cases by other writers in the KM field. The outcome of the research is a planning approach, which is given the name: “The problem exploration approach”. The approach is intended for the generation of ideas of possible systems, as a strategic part of knowledge management systems planning. The purpose of the planning approach is to support the creation of a portfolio of KMS. A KMS portfolio is a structured set of information systems that could be developed for an organizational unit. The approach consists of five planning frameworks, all targeting different aspects of an organization. “The problem exploration approach” and its development process are then examined for more general insights into the subject of strategic KM planning. As an outcome of this examination a 12-point program for balancing a planning approach is presented.

    IT Governance in a Public Organization in a Developing Country: A Case Study of a Governmental Organization2015In: Procedia Computer Science, E-ISSN 1877-0509, Vol. 64, p. 450-456Article in journal (Refereed)
    Abstract [en]

    The application of Information Technology Governance (ITG) was motivated by the private sector in the 90s, as a way to achieve excellence, provide new services, and increase profitability of IT investments. Therefore the organizations from the public sector has shortly followed those from the private sector realizing the benefits of having an effective ITG implementation that could better serve the implementation of IT plans, projects and programs in their organizations. Reviewing the research literature in this field, we have found a shortage of studies regarding ITG implementation into the public sector organizations in developing countries. Research has been conducted mainly in organizations from the private sector and specifically in the developed countries and very few in the public sector organizations in developing countries. Therefore this research has focused on the application of ITG in a public organization particularly in a governmental organization in a developing country by analysing ITG practices in place. The research method used in this study was interpretive case study and the data collection was done through interviews as primary data together including secondary data collected from progress reports, policies and procedure reports of the governmental organization. The results of this research concluded, that there was an unintentional implementation of ITG in the studied governmental organization and that there is a need to improve the ITG structures, processes and relational mechanisms that will promote accountability of the IT projects and contribute to an effective ITG implementation in this organization.

    A Prototype For HI²Ping Information Security Culture and Awareness Training2012In: 2012 International Conference on E-Learning and E-Technologies in Education (ICEEE), IEEE, 2012, p. 32-36Conference paper (Refereed)
    Abstract [en]

    In this short paper, we propose a security culture and awareness training platform that suite different learning styles and preferences. The objective is to operationalize the platform for improving individuals security awareness and learn more about their security mental models as well as how their cultural background influence their perception of security. Useful application of the tool is to enhance the effectiveness of security knowledge transfer in a security incident response process management and to develop staff commitment to security policies at organizations. The tool can also help on enabling a global security culture by creating a common understanding of security best practices. Qualitative results show the tool can play a promising role in security education as it combines different mediums for communicating the required information to fit the audience different learning styles.
