    The impact of different organizational cultures on IT outsourcing relationship management2013Inngår i: International Journal of Innovation in the Digital Economy, ISSN 1947-8305, Vol. 4, nr 2, 50-66 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Globalization has affected the organizations in many aspects such as structure, architecture, internal/external strategies and sourcing management. Outsourcing is one of the recent business strategies used to provide IT needs via external agents. The relationship between the service buyer and provider companies is a constituent playing a significant role in IT outsourcing success or failure. This research has a focus on the influence of organizational culture of buyer companies on the specific factors of trust, cooperation, communication and commitment in their relationship with the IT service provider. Two explorative case studies are done in global companies using ITO which revealed the presence of organizational culture effect. Particularly, being innovative, having open discussion as an organizational culture and looking for extending contracts with providers as a strategy, appeared as the major difference between the two cases organizational culture; which influences the studied factors of ITO relationship in this research.

    Facing The Digitalization Challenge: Why Organizational Culture Matters and How It Influences IT Governance Performance2017Inngår i: 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.

    The Influence of Culture on IT Governance: A Literature Review2014Inngår i: 2014 47th Hawaii International Conference on System Sciences (HICSS) / [ed] Sprague, R. H., IEEE Computer Society, 2014, 4436-4445 s.Konferansepaper (Fagfellevurdert)
    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.

    The Influence of Organizational Culture on IT Governance Performance: Case of The IT Department in a Large Swedish Company2016Inngår i: Proceedings of the 49th Annual Hawaii International Conference on System Sciences / [ed] Tung X. Bui, Ralph H. Sprague, Jr., IEEE Computer Society, 2016Konferansepaper (Fagfellevurdert)
    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 Organization2017Inngår i: Information Technology Governance in Public Organizations: Theory and Practice / [ed] Lazar Rusu, Gianluigi Viscusi, Cham, Switzerland: Springer, 2017, nr 0, 229-252 s.Kapittel i bok, del av antologi (Fagfellevurdert)
    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]

    Information technology governance (ITG) is one of the top challenges of managers today and culture in different level can have an important role while implementing IT governance. This is a new and significant issue, which has not been investigated deeply. This paper sets out to provide a systematic review of the literature, focusing on the role of culture in IT governance. The literature review findings are categorized through the lens of IT governance's five focus areas which are IT strategic alignment, IT value delivery, Risk management, IT resource management and Performance measurement. This study contributes to the field of IT governance by reviewing and discussing the existing literature on the role of culture on IT governance. This literature review resulted that there are few research studies in this topic and many of the IT governance focus areas are not covered regarding the role of culture in these IT governance areas.

    Architectural Description of an Automated System for Uncertainty Issues Management in Information Security2010Inngår i: International Journal of computer Science and Information Security, ISSN 1947-5500, Vol. 8, nr 3, 59-67 s.Artikkel i tidsskrift (Fagfellevurdert)
    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

    CryptoNET: integrated secure workstation2009Inngår i: International Journal of Advanced Science and Technology, ISSN 2005-4238, Vol. 12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In most of the current applications security is usually provided individually. This means that various applications use their own security mechanisms and services, applied only to their own resources and functions. Furthermore, procedures to configure security parameters are usually inconvenient and complicated for non-technical users. As an alternative to this approach, we have designed and implemented Secure Workstation, which represents an integrated security environment and protects local IT resources, messages and operations across multiple applications. It comprises five components, i.e. four most commonly used PC applications: Secure Station Manager (equivalent to Windows Explorer), Secure E-Mail Client, Secure Documents System, and Secure Browser. These four components for their security extensions use functions and credentials of the fifth component, Generic Security Provider [5]. With this approach, we provide standard security services (authentication, confidentiality, and integrity and access control) and also additional, extended security services, such as transparent handling of certificates, use of smart cards, strong authentication protocol, SAML based single-singe-on, secure sessions, and other security functions, to all PC applications with the same set of security modules and parameters.

    An e-learning reproductive health module to support improved student learning and interaction: a prospective interventional study at a medical school in Egypt2012Inngår i: BMC Medical Education, ISSN 1472-6920, Vol. 12, 11- s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The Public Health (PH) course at the medical college of Cairo University is based on traditional lectures. Large enrollment limits students' discussions and interactions with instructors. Aim: Evaluate students' learning outcomes as measured by improved knowledge acquisition and opinions of redesigning the Reproductive Health (RH) section of the PH course into e-learning and assessing e-course utilization. Methods: This prospective interventional study started with development of an e-learning course covering the RH section, with visual and interactive emphasis, to satisfy students' diverse learning styles. Two student groups participated in this study. The first group received traditional lecturing, while the second volunteered to enroll in the e-learning course, taking online course quizzes. Both groups answered knowledge and course evaluation questionnaires and were invited to group discussions. Additionally, the first group answered another questionnaire about reasons for non-participation. Results: Students participating in the e-learning course showed significantly better results, than those receiving traditional tutoring. Students who originally shunned the e-course expressed eagerness to access the course before the end of the academic year. Overall, students using the redesigned e-course reported better learning experiences. Conclusions: An online course with interactivities and interaction, can overcome many educational drawbacks of large enrolment classes, enhance student's learning and complement pit-falls of large enrollment traditional tutoring.

    Tweens negotiating identity online – Swedish girls' and boys' reflections on online experiences2013Inngår i: Journal of Youth Studies, ISSN 1367-6261, E-ISSN 1469-9680, Vol. 16, nr 8, 951-969 s.Artikkel i tidsskrift (Fagfellevurdert)
    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 Ghana2014Inngår i: ICTs and the Millennium Development Goals: a United Nations Perspective, Springer, 2014, nr 2013, 223-235 s.Kapittel i bok, del av antologi (Annet vitenskapelig)
    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 Ghana2014Inngår i: International Journal of Innovation in the Digital Economy, ISSN 1947-8305, E-ISSN 1947-8313, Vol. 5, nr 2, 14-23 s.Artikkel i tidsskrift (Fagfellevurdert)
    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.

    Business-IT Alignment in Trade Facilitation: A Case Study2010Inngår i: Organizational, Business, and Technological Aspects of the Knowledge Society / [ed] Lytras, M.D.; Ordonez De Pablos, P.; Ziderman, A.; Roulstone, A.; Maurer, H.; Imber, J.B., Berlin Heidelberg: Springer-Verlag , 2010, Vol. 112, 146- s.Konferansepaper (Annet vitenskapelig)
    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.

    IT-supported Knowledge Repositories: Increasing their Usefulness by Supporting Knowledge Capture2008Doktoravhandling, monografi (Annet vitenskapelig)
    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 system2015Inngår i: Education and Information Technologies: Official Journal of the IFIP technical committee on Education, ISSN 1360-2357, E-ISSN 1573-7608, Vol. 20, nr 1, 21-36 s.Artikkel i tidsskrift (Fagfellevurdert)
    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.

    The Usefulness of ICT Support Systems for Thesis Courses: Learners' Perspectives at Bachelor and Master Level2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Doing a bachelor’s or master’s degree is a journey that leads to success or attrition (dropout). Previous research show to the significance of considering learners’ perspectives and their need for information and different types of interaction. This can be done through online ICTSS (information and communication technology support systems). The overall aim of this dissertation was to create knowledge about how the use of ICTSS can facilitate different types of interaction and support learners in order to reduce thesis problems and attrition and to enhance the quality of the thesis outcomes. The aim was operationalized by two research questions scrutinizing the interaction problems in the thesis process and investigating how the use of ICTSS can facilitate different types of interaction to reduce such problems and attrition, and to enhance the learning opportunities and quality of the thesis outcomes. To answer the research questions, five main studies were performed by applying different research methods on a case study. The empirical studies were performed at the Department of Computer and Systems Sciences (DSV) at Stockholm University, Sweden. The respondents were different learners (students) with active thesis projects at the bachelor or master level in different programs at DSV between 2012 and 2015. For the first two studies, conceptual and content analysis of the data collected from the case study was performed. For the three other studies, open-ended online questionnaires (survey) and interviews were conducted. On the basis of the findings, three main types of interaction issues were developed which related to the need for more learner-content, peer-to-peer, and learner-supervisor interaction in the thesis process. The hypothesis was that the interaction issues could be reduced by implementing a set of strategic suggestions through the use of an ICTSS including a set of functionalities and resources. The usefulness of these functionalities and resources was evaluated with regard to the learners’ perception and experiences. The findings were categorized to facilitate learner-content, peer-to-peer, and learner-supervisor interaction, as well as management of the contents, supervision, and communication of the supervisory team. From these categories, a conceptual framework was developed in this dissertation to illustrate how the use of the ICTSS supports the thesis process. In conclusion, providing access to a set of structured e-resources and supporting educational communication through different types of interaction with peers and the supervisory team, enables learners’ self-managed learning and facilitates similar learning opportunities for learners in thesis courses.

    Peer Portal: Quality Enhancement in Thesis Writing Using Self-Managed Peer Review on a Mass Scale2013Inngår i: International Review of Research in Open and Distance Learning, ISSN 1492-3831, E-ISSN 1492-3831, Vol. 14, nr 1, 186-203 s.Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    This paper describes a specially developed online peer-review system, the Peer Portal, and the first results of its use for quality enhancement of bachelor's and master's thesis manuscripts. The peer-review system is completely student driven and therefore saves time for supervisors and creates a direct interaction between students without interference from supervisors. The purpose is to improve thesis manuscript quality, and thereby use supervisor time more efficiently, since peers review basic aspects of the manuscripts and give constructive suggestions for improvements. The process was initiated in 2012, and, in total, 260 peer reviews were completed between 1st January and 15th May, 2012. All peer reviews for this period have been analyzed with the help of content analysis. The purpose of analysis is to assess the quality of the students work. The results are categorized in four groups: 1) excellent (18.1%), 2) good (22.7%), 3) fragmented (18.5%), and 4) poor (40.7%). The overall result shows that almost 40% of the students produced excellent or good peer reviews and almost as many produced poor peer reviews. The result shows that the quality varies considerably. Explanations of these quality variations need further study. However, alternative hypotheses followed by some strategic suggestions are discussed in this study. Finally, a way forward in terms of improving peer reviews is outlined: 1) development of a peer wizard system and 2) rating of received peer reviews based on the quality categories created in this study. A Peer Portal version 2.0 is suggested, which will eliminate the fragmented and poor quality peer reviews, but still keep this review system student driven and ensure autonomous learning.

    Learners’ Perceptions on the Structure and Usefulness of e-Resources for the Thesis Courses2014Inngår i: European Journal of Open and Distance Learning, ISSN 1027-5207, E-ISSN 1027-5207, Vol. 17, nr 1, 154-171 s.Artikkel i tidsskrift (Fagfellevurdert)
    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 Sweden2016Inngår i: The International Review of Research in Open and Distributed Learning, ISSN 1492-3831, Vol. 17, nr 3, 360-383 s.Artikkel i tidsskrift (Fagfellevurdert)
    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.

    ICT-supported peer interaction among learners in Bachelor's and Master's thesis courses2016Inngår i: Computers and education, ISSN 0360-1315, E-ISSN 1873-782X, Vol. 94, 276-297 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Peer interaction and collaborative learning through the use of ICT (Information and Communication Technology) is used to an increasing extent in higher education. Universities attempt to motivate learners (students) to support their peers to enhance the quality of learning outcomes. This study monitors how an ICTSS (ICT-based Support System) facilitates peer interaction in the Bachelor’s and Master’s thesis process. The aim of the study was to investigate learners’ perception of usefulness of an ICTSS for peer interaction and the influencing factors on the quality of the peer interaction. The ICTSS was developed at an institution in Sweden (the institution’s name has been removed during the double-blind review). The system facilitates peer interaction in three ways: peer reviews, active participation, and final opposition. The study employed a mixed-method approach, which included an online survey followed by in-depth interviews. The target groups were learners at the Bachelor’s and Master’s level in computer science and information systems. The findings showed that learners perceived the peer interaction useful to enhance the quality of the thesis outcomes. However, there are influencing factors affecting the quality of peer interaction, in different phases of the thesis process. Examples of these factors are the quality of thesis manuscripts, supervisors’ control and grading of the process, clear instructions and guidelines, learners’ understanding of the peer interaction and why it takes place, previous training and learners’ motivation to perform peer reviews. Following these factors, the study developed a set of strategic suggestions from both pedagogical and technical aspects to enhance the peer interaction in the thesis process. Considering these suggestions makes the use of the ICTSS more effective to enhance the quality of thesis learning outcomes.

    Students’ Perspectives on Utility of Mobile Applications in Higher Education2013Inngår i: Trends in Mobile Web Information Systems: Revised Selected Papers / [ed] Maristella Matera, Gustavo Rossi, Springer Publishing Company, 2013, 44-56 s.Konferansepaper (Fagfellevurdert)
    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.

    Using text prediction for facilitating input and improving readability of clinical text2013Inngår i: MedInfo 2013: Proceedings of the 14th World Congress on Medical and Health Informatics / [ed] Christoph Ulrich Lehmann, Elske Ammenwerth, Christian Nøhr, IOS Press, 2013, 1149-1149 s.Konferansepaper (Fagfellevurdert)
    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.

    Expansion of medical vocabularies using distributional semantics on Japanese patient blogs2016Inngår i: Journal of Biomedical Semantics, ISSN 2041-1480, E-ISSN 2041-1480, Vol. 7, 58Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Research on medical vocabulary expansion from large corpora has primarily been conducted using text written in English or similar languages, due to a limited availability of large biomedical corpora in most languages. Medical vocabularies are, however, essential also for text mining from corpora written in other languages than English and belonging to a variety of medical genres. The aim of this study was therefore to evaluate medical vocabulary expansion using a corpus very different from those previously used, in terms of grammar and orthographics, as well as in terms of text genre. This was carried out by applying a method based on distributional semantics to the task of extracting medical vocabulary terms from a large corpus of Japanese patient blogs. Methods: Distributional properties of terms were modelled with random indexing, followed by agglomerative hierarchical clustering of 3x100 seed terms from existing vocabularies, belonging to three semantic categories: Medical Finding, Pharmaceutical Drug and Body Part. By automatically extracting unknown terms close to the centroids of the created clusters, candidates for new terms to include in the vocabulary were suggested. The method was evaluated for its ability to retrieve the remaining n terms in existing medical vocabularies. Results: Removing case particles and using a context window size of 1 + 1 was a successful strategy for Medical Finding and Pharmaceutical Drug, while retaining case particles and using a window size of 8 + 8 was better for Body Part. For a 10n long candidate list, the use of different cluster sizes affected the result for Pharmaceutical Drug, while the effect was only marginal for the other two categories. For a list of top n candidates for Body Part, however, clusters with a size of up to two terms were slightly more useful than larger clusters. For Pharmaceutical Drug, the best settings resulted in a recall of 25 % for a candidate list of top n terms and a recall of 68 % for top 10n. For a candidate list of top 10n candidates, the second best results were obtained for Medical Finding: a recall of 58 %, compared to 46 % for Body Part. Only taking the top n candidates into account, however, resulted in a recall of 23 % for Body Part, compared to 16 % for Medical Finding. Conclusions: Different settings for corpus pre-processing, window sizes and cluster sizes were suitable for different semantic categories and for different lengths of candidate lists, showing the need to adapt parameters, not only to the language and text genre used, but also to the semantic category for which the vocabulary is to be expanded. The results show, however, that the investigated choices for pre-processing and parameter settings were successful, and that a Japanese blog corpus, which in many ways differs from those used in previous studies, can be a useful resource for medical vocabulary expansion.

    Medical vocabulary mining using distributional semantics on Japanese patient blogs2014Inngår i: Proceedings of the 6th International Symposium on Semantic Mining in Biomedicine, 2014, 57-62 s.Konferansepaper (Fagfellevurdert)
    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.

    Strategic Planning of Knowledge Management Systems: A Problem Exploration Approach2007Doktoravhandling, monografi (Annet vitenskapelig)
    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.
