    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 impact of different organizational cultures on IT outsourcing relationship management2013In: International Journal of Innovation in the Digital Economy, ISSN 1947-8305, Vol. 4, no 2, p. 50-66Article in journal (Refereed)
    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 Performance2017In: Information Systems Development: Advances in Methods, Tools and Management: Proceedings / [ed] N. Paspallis, M. Raspopoulos, C. Barry, M. Lang, H. Linger, C. Schneider, Association for Information Systems, 2017Conference paper (Refereed)
    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.

    Culture Influence on IT Governance: What We Have Learned?2017In: Organizational Culture and Behavior: Concepts, Methodologies, Tools, and Applications, IGI Global, 2017, no 2017Chapter in book (Other academic)
    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.

    The Influence of Organizational Culture on IT Governance Performance: Case of The IT Department in a Large Swedish Company2016In: Proceedings of the 49th Annual Hawaii International Conference on System Sciences / [ed] Tung X. Bui, Ralph H. Sprague, Jr., IEEE Computer Society, 2016Conference paper (Refereed)
    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.

    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.

    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.

    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.

    Business-IT Alignment in Trade Facilitation: A Case Study2010In: 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, p. 146-Conference paper (Other academic)
    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 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 and Distance Learning, ISSN 1027-5207, 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: The International Review of Research in Open and Distributed Learning, 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 Publishing Company, 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.

    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.

    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.

    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.

    Abstract [en]

    In this short paper we present and discuss the findings of a case study aimed at developing social security metrics for modeling the security culture of certain individuals. Using these metrics we have modeled the security culture of IT workers individuals from Saudi Arabia. We suggest these metrics can be used for modeling and comparing different security cultures to develop a global security culture required for effective global response to cyber security issues. We start by reviewing the latest research on the social aspects of information security. Then we highlight the history of the under-development social security metrics. Afterward we discuss the setup of the case study and the methodology used. Finally, we discuss the experiment results and suggested further research work.

    Security from a Systems Thinking Perspective - Applying Soft Systems Methodology to the Analysis of an Information Security Incident2014In: Proceedings of the 58th Annual Meeting of the International Society for the Systems Sciences (ISSS 2014), York: International Society for the Systems Sciences ( ISSS ) , 2014, p. 1-17Conference paper (Refereed)
    Abstract [en]

    Applying systems theory to information security enables security analysts to consider the socio-technical role of the security system instead of only focusing on the technical part. Systems theory can also equip security analysts with the skills required to have a holistic and an abstract level of understanding of the security problem in their organisations and to proactively define and evaluate existing risks. The Soft Systems Methodology (SSM) developed by Peter Checkland was created in order to deal with unstructured situations where human beings are part of the socio-technical system. In this paper, SSM is applied as a framework to diagnose a real case security incident in an organisation. The purpose of this application is to demonstrate how the methodology can be considered a beneficial tool for security analysts during security incident management and risk analysis. Literature review and experience indicate an existing lack of customisable incident response tools that facilitate communication and elaboration within organizations during incident management. In addition to the fact that these tools are mainly technical and don’t take the human factor into consideration. Using SSM as such, we define the security attack as a human activity transformation system that transforms a security event triggered by an attacker into a security breach that cause damage to the victim organisation. The attack system is then modelled to include a number of dependent activity sub-systems that interact with each other and their environment including the security control activity systems. By having such systemic perception of a security attack, security analysts, we suggest, can have a holistic perception under what conditions a security attack has succeeded and what elements of the socio-technical system and its environment should have been considered in order to mitigate and reduce the risk exposure.

We then show the need to consider the social dimension of information systems security as recommended by number of global security consortiums. Afterward we review the development of some of the main currently existing global cyber security warning systems. Finally we present our suggested socio-technical coordination platform to feature socio-technical enabled cyber security warning systems.

    Pseudonymisation of Personal Names and other PHIs in an Annotated Clinical Swedish Corpus2012In: LREC 2012, Eighth International Conference on Language Resources and Evaluation / [ed] Nicoletta Calzolari et al., 2012Conference paper (Refereed)
    Abstract [en]

    Today a large number of patient records are produced and these records contain valuable information, often in free text, about the medical treatment of patients. Since these records contain information that can reveal the identity of patients, known as protected health information (PHI), the records cannot easily be made available for the research community. In this research we have used a PHI annotated clinical corpora, written in Swedish, that we have pseudonymised. Pseudonymisation means to replace the sensitive information with fictive information for example real personal names are replaced with fictive personal names based on the gender of the real names and family relations. We have evaluated our results and our five respondents of who three were clinicians found that the clinical text looks real and is readable. We have also added pseudonymisation for telephone numbers, locations, health care units, dates and ages. In this paper we also present the entire de-identification and pseudonymisation process of a sample clinical text.

    Abstract [en]

    A set of standard answers facilitates answering emails at customer care centers. Matching the text of user emails to the standard answers may not be productive because they do not necessarily have the same wording. Therefore we examine archived email-answer pairs and establish query-answer term co-occurrences. When a new user email arrives, we replace query words with most co-occurring answer words and obtain a “shadow answer”, which is a new query to retrieve standard answers. As a measure of term co-occurrence strength we test raw term co-occurrences and Pointwise Mutual Information.

    Abstract [en]

    Approaches to determining the factuality of diagnoses and findings in clinical text tend to rely on dictionaries of marker words for uncertainty and negation. Here, a method for semi-automatically expanding a dictionary of marker words using distributional semantics is presented and evaluated. It is shown that ranking candidates for inclusion according to their proximity to cluster centroids of semantically similar seed words is more successful than ranking them according to proximity to each individual seed word.
