    Äldre män och kvinnor som med-aktörer i design av tränings-appar för fallprevention2013Konferansepaper (Fagfellevurdert)
    Abstract [sv]

    Bakgrund och syfte:Det finns en uppsjö av olika fallpreventiva evidensbaserade träningsprogram för äldre i ordinärt boende. Även om evidensgraden är hög för viss träning finns det svårigheter med att få äldre personer att utföra träningen. Vissa motivationsfaktorer och hindrande faktorer har redan identifierats och forskningen visar att skräddarsydda, hembaserade träningsprogram med möjlighet till regelbunden återkoppling är det som fungerar bäst. Applikationer till mobiltelefoner och surfplattor erbjuder denna möjlighet, och har funnits sedan en längre tid, men dessa vänder sig oftast till yngre och medelålders personer. Det finns ännu ingen applikation som är baserad på de äldres egna önskemål. Syftet med studien är att undersöka hur friska äldre män och kvinnor i ordinärt boende resonerar och vilka övningar de föredrar när de deltar i utveckling och design av ett fallpreventivt träningsprogram i form av en applikation till smarta telefoner och surfplattor. Metoder:18 deltagare > 70 år. Deltagande och uppskattande aktionsforskning samt fokusgruppsintervjuer och workshops. Kvalitativ innehållsanalys. Resultat:De preliminära resultaten visar att när äldre män och kvinnor i ordinärt boende deltar i utvecklingen av ett fallpreventivt träningsprogram för smarta telefoner och surfplattor har de många idéer, tankar och erfarenheter som kan fungera som motiverande faktorer i syfte att utföra regelbunden fallpreventiv träning. Konklusion:Implementeringen och följsamheten för evidensbaserade fallpreventiva träningsprogram är otillräcklig. Denna studie bidrar med kunskaper för att designa skräddarsydda, hembaserade fallpreventiva träningsprogram för friska äldre personer i ordinärt boende.

    Fall risk awareness and safety precautions taken by older community-dwelling women and men: A qualitative study using focus group discussions2015Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, nr 3, artikkel-id e0119630Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: Daily life requires frequent estimations of the risk of falling and the ability to avoid a fall. The objective of this study was to explore older women's and men's understanding of fall risk and their experiences with safety precautions taken to prevent falls.METHODS: A qualitative study with focus group discussions was conducted. Eighteen community-dwelling people [10 women and 8 men] with and without a history of falls were purposively recruited. Participants were divided into two groups, and each group met four times. A participatory and appreciative action and reflection approach was used to guide the discussions. All discussions were audio recorded and transcribed verbatim. Data were analysed by qualitative content analysis, and categories were determined inductively.FINDINGS: Three categories describing the process of becoming aware of fall risks in everyday life were identified: 1] Facing various feelings, 2] Recognizing one's fall risk, and 3] Taking precautions. Each category comprised several subcategories. The comprehensive theme derived from the categories was "Safety precautions through fall risk awareness". Three strategies of ignoring [continuing a risky activity], gaining insight [realizing the danger in a certain situation], and anticipating [thinking ahead and acting in advance] were related to all choices of actions and could fluctuate in the same person in different contexts.CONCLUSIONS: The fall risk awareness process might be initiated for various reasons and can involve different feelings and precautions as well as different strategies. This finding highlights that there are many possible channels to reach older people with information about fall risk and fall prevention, including the media and their peers. The findings offer a deeper understanding of older peoples' conceptualizations about fall risk awareness and make an important contribution to the development and implementation of fall prevention programmes.

    Increasing Transparency and Privacy for Online Social Network Users: USEMP Value Model, Scoring Framework and Legal2016Inngår i: Privacy Technologies and Policy: Third Annual Privacy Forum, APF 2015, Luxembourg, Luxembourg, October 7-8, 2015, Revised Selected Papers / [ed] Bettina Berendt; Thomas Engel; Demosthenes Ikonomou; Daniel Le Métayer; Stefan Schiffner, Cham: Encyclopedia of Global Archaeology/Springer Verlag, 2016, s. 38-59Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this paper we present research results from the multi-disciplinary EU research project USEMP (USEMP is a project funded from EU research framework, additional information about project scope and deliverables are available at project’s public website at: http://​www.​usemp-project.​eu/​). In particular, we look at the legal aspects of personal data licensing and profile transparency, the development of a personal data value model in Online Social Networks (OSNs) and the development of disclosure scoring and personal data value frameworks. In the first part of the paper we show how personal data usage licensing and profile transparency for OSN activities provides for Data Protection by Design (DPbD). We also present an overview of the existing personal data monetization ecosystem in OSNs and its possible evolutions for increasing privacy and transparency for consumers about their OSN presence. In the last part of the paper, we describe the USEMP scoring framework for personal information disclosure and data value that can assist users to better perceive how their privacy is affected by their OSN presence and what the value of their OSN activities is.

    Ensemble artifacts: from viewing to designing in action design research2013Inngår i: Systems, Signs & Actions, ISSN 1652-8719, E-ISSN 1652-8719, Vol. 7, nr 1, s. 73-81Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Action Design Research (ADR) is a research method for generating design knowledge through building and evaluating ensemble artifacts. In this paper, we respond to Goldkuhl’s critical review of the conceptualization of IT artifact in ADR. In particular, the review problematizes the so-called “conceptual journey” from an ensemble view to ensemble artifact, and suggests that this journey restricts the use of ADR. We recognize Goldkuhl’s critique as a valuableopportunity to clarify our thinking and elaborate the rationale behind ensemble artifact. We maintain that the notion of ensemble artifact in ADR is appropriate because it highlights the forward-looking orientation of designing artifacts and stresses the importance of the context for the evolution and use of the resulting artifact. It stands in contrast to the retrospective orientation of the ensemble view nomenclature from Orlikowski and Iacono that we borrowed and extended for ADR. Finally, we endorse Goldkuhl’s proposed communicative view as auseful addition to the toolkit of ADR researchers who can study the design of communicative tool artifacts.

    Concise preservation by combining managed forgetting and contextualization remembering2013Rapport (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    This report covers a systematic study of existing research literature on smooth bi-directional preservation transition between producers system (active system) and a Synergetic Preservation system. This transition is meant to be as transparent as possible to the user, and also be able to fetch material from the preservation system in a smooth way. The report also includes a study on gaps that could be identified from existing research and what this integration would need to cover, and how it conceptually could work in Content Management Systems (use case: Typo3) and Personal Information Management (use case: Semantic Desktop / PIMO). The report groups activities into three high-level workflows; Preservation planning and administration, Preservation, and Access and retrieval. In these workflows, the contextual preservation administration, which link the preservation and storage services to particular information systems and maintains the contextualized preservation and access workflows, interfaces and ontologies, is something that needs further development during the project, since it includes many of the project specific peculiarities. This also goes for the other components of the middleware, which also are contextually aware, and part of the "forgetting" approach. Both workshop results and the literature review shows that integration of these workflows with the producing workflows should be done in a way that makes it low-effort, generic, and transparent – which goes well together with what the project set out to do. Most likely some sort of automatic appraisal needs to take place already in the producing systems, and the challenge here would be to make it non-intrusive but effective. The ideas and results from this report will serve as a starting point for design and integration that will take place in WP5 of the ForgetIT project, in particular for T5.2 and T5.3 as well as D5.2. The ideas in this report are however not strict rules to be followed, and may be altered or improved as work continues in above mentioned tasks. Any such actions will be reflected in D5.2 or subsequent reports.

    Grounding theory from Delphi studies2011Inngår i: International Conference on Information Systems 2011, ICIS 2011, Atlanta: Association for Information Systems, 2011, Vol. 3, s. 2022-2035Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The Delphi method is recommended for exploratory research in emerging research areas. Despite earlier suggestions for using the Delphi method for theory creation, few analytical tools are provided for this purpose. However, Grounded Theory is especially devoted to creating theories from qualitative data. This paper describes an enhanced Delphi method which integrates data analysis techniques from Grounded Theory. The resulting Grounded Delphi Method (GDM) improves Delphi studies by bringing in a data collection technique that focuses explicitly on the identification of the reasons and consequences for issues, ranked by experts. Moreover, the techniques of open and axial coding support the discovery of theoretical concepts from the initial Delphi issues. In turn, the ranking process of the Delphi method provides a rigorous means for selecting core categories for theory development, which decreases researcher interference on this issue.

    Theorizing about Software Development Practices2015Inngår i: Science of Computer Programming, ISSN 0167-6423, E-ISSN 1872-7964, Vol. 101, s. 124-135Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The paper focuses on the challenge of generating theoretical support for software development, especially when human software developers are involved in the software development process. We outline a model, “Coat Hanger”, for theorizing about development practices. The model focuses on the intended rationale for the actual realization and resulting impacts of using particular practices in varying contexts. To illustrate the use of the model, we have studied recent practice-oriented articles in the journal Science of Computer Programming. A survey of articles in the journal between 2010 and 2013 showed that out of 371 articles, only four studied software development in professional organizations with actual software practitioners as informants. The Coat Hanger model was then used to identify the theoretical strengths and weaknesses of these four practice descriptions. The analysis is used as the basis to declare the potential of our model as a conceptual aid for more structured theorizing about software development practices. The contribution of the model is the introduction of a concretization of how theorizing can be done through reflection-in-action, instead of regarding research on software practices plainly from the prevailing viewpoint of technical rationality.

    Integrating Contemporary Content Management and Long-Term Digital Preservation: A Design Problem2015Inngår i: Nordic Contributions in IS Research: 6th Scandinavian Conference on Information Systems, SCIS 2015, Oulu, Finland, August 9-12, 2015, Proceedings / [ed] Harri Oinas-Kukkonen; Netta Iivari; Kari Kuutti; Anssi Öörni; Mikko Rajanen, Cham: Springer International Publishing , 2015, s. 92-107Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The fields of long-term digital preservation (DP) and enterprise content management (ECM) have remained, until recently, rather separated. Along with increasing amounts of digital content and evolving DP services, there is a need for maximal automation of preservation processes from ECM systems instead of continuing current resource-consuming practices. This paper aims at a design problem definition on the integration of ECM and DP solutions. In order to motivate and to define the problem in more detail, we conducted a review on ECM and DP literatures touching the issue. The review reveals a research gap addressing a need for designing new middleware solutions for interactive processes between ECM and DP. We suggest a general-level model of three such processes between ECM and DP: preservation administration, pre-ingest, and access. The article concludes with avenues for future research on novel solutions for integrating DP with contemporary ECM and other information systems in organizations.

    A bottom-up approach to carry out pre-studies for the implementation of electronic archives: a case study from a Swedish organisation2017Inngår i: Archiving 2017: Final Program and Proceedings, Society for Imaging Science and Technology , 2017, s. 44-48Konferansepaper (Fagfellevurdert)
    Abstract [en]

    n this paper a bottom-up approach to carry out preliminary studies for the implementation of electronic archives is presented. Pre-studies are a standard procedure ahead of putting forward a project for the implementation of electronic archives. The top-down method, fundament for presented approach relies on the activities of Problem Analysis, Goal Analysis, Business Analysis, Change Needs Analysis and Determination of Change Actions (iteratively and in that order). The bottom up approach proposes change, positioning Goal Analysis after Business Analysis due to the way of stipulating goals from this approach become stronger since it put forward employees goals as the driving forces for change. The bottom-up approach more clearly discloses complexity and to some extent competing and disperse goals within studied organisation.

    A framework for the development of archival information systems2006Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In this thesis a framework for the development of an Archival Information Systems are proposed. IT community and long-term digital preservation research has not addressed the development of digital archival tools. It community addresses Archives and digital archiving almost as a storage place aimed for backup services. Long-term digital preservation research has put efforts in metadata research, and in the use of different preservation techniques in order to preserve digitally stored information. Archival Information Systems is and its development is a natural part of the field of Long-term Digital Preservation. Archival Information Systems are aimed to receive maintain, support digital preservation issues and give access to digitally stored information. This digitally stored information consists in different kind of documents or records physically manifested in computer files, databases, etc. Archival Information Systems are a special kind of Information Systems. As every specialized kind of Information System, Archival Information Systems development must be preceded by a specialized way of thinking. This thesis proposes a specialized way of thinking, a framework, for the development of Archival Information Systems. The proposed framework is based on The Records Continuum Model and The OAIS Reference Model as major fundaments. The framework consists on six levels of substitutionality. The lowest level, the software, is prone to high substitutionality. The highest levels are constituted by The OAIS Reference Model and The Records Continuum as the highest. The framework is a theoretical approach to Archival Information Systems Development and explained in terms of epistemological and ontological for it. Some important epistemological and ontological principles for Archival Information Systems are: Dealing with Archival Information System is dealing with making digital recorded information accessible. Records are logical rather than physical entities. Records have continuing value by means of information exchangeability. Forward Compatibility is achieved by means of open attitude and open standards. Accessibility and long-term preservation is stretching the longevity of records across time-space. This framework had been tested theoretically based on the expertise from Information Systems developers working in archival organizations. This evaluation shows strengths and weaknesses in the framework and the need of further development of it, and calls for putting forward efforts in deeper research of the framework, Archival Information Systems and long-term digital preservation issues.

    Evaluation of a digital repository2008Inngår i: Archiving 2008: June 24 - 27, 2008, Bern, Switzerland ; final program and proceedings ; [Fifth Annual Archiving Conference], Springfield, Va: Society fo Imaginig Science , 2008, s. 120-124Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper is the result of an evaluation of an organisation as a Trusted Repository. The evaluation was carried out in November 2007, using parts of the existing guidelines concerning the certification of Trusted Repositories. The contributions of are 1) findings on organisation concerning its commitment towards its stakeholders and archival holdings and 2) findings about repository evaluation. The findings show that a highly committed and competent organisation is reliable as a trusted repository and there is a need of continuity evaluating digital repositories since an evaluation does not show the reliability of an organisation as a trusted repository in the long-term.

    Abstract [en]

    Archives are an essential part of our societal memory. The use of Information Technology (IT) in archival context has pointed out the need of preserving digital information. There is a need of methods and techniques for preservation activities and the development of supporting tools. Archival Information Systems are a special kind of information systems. The development of Archival Information Systems has to be non-ad hoc implementation based upon archival and long-term preservation thinking. The paper A Foundation for Archival Information Systems Development (Quisbert, Hagerfors, 2006) proposes a thinking framework based upon the Records Continuum Model and the OAIS Reference Model. In this paper, a Computational Independent Model for an Archive Information System (AIS), based upon mentioned framework, is proposed. The Model Driven Architecture, proposed by the Object Management Group, has been chosen as an example for the creation of this model.The Centre for Long-term Digital Preservation (CLDP) connected to the Luleå University of Technology (LTU) in Sweden, is an R&D division working with digital preservation issues. The intention of the proposed model is to be the fundament for developing a prototype for an AIS, at this centre. Empirical contribution to this model has been given by archivists, by experimental student projects at the LTU, and systems developers at the CLDP. Later, a complete software implementation base upon the proposed framework should support long-term preservation of digital information by reflecting important characteristics of the Continuum Model and the OAIS Reference Model.

    On long-term digital preservation information systems: a framework and characteristics for development2008Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    There is a need for the long-term preservation of digitally recorded information, for historical, juridical, democratic and recollective purposes. The digital preservation realm is facing two major problems: hardware and software obsolescence and the rapid growth of information. The problems jeopardise the possibilities for long-term retention and accessibility to digitally recorded information. These problems cannot be solved, but alleviated by managing digital preservation in a long-term perspective. For this to be achieved, special competence is needed. For this reason, Long-term Digital Preservation has emerged as a new field of research and practice, addressing new models, methods and tools. So far, Digital Preservation systems have not been elaborated from an Information Systems perspective. In this thesis, a framework for Long-term Digital Preservation Information Systems (LDP-IS) and some characteristics of such systems and their development are put forth. The research question posed is: What might constitute a framework for realising systems for long-term digital preservation? Subordinated questions are: What are feasible components of such a framework? and What might characterise systems based on such a framework? The research approach is exploratory since this is a new field of investigation. The results comprise an integrated trinity of preservation systems: the framework itself, the concept of LDP-IS and several characteristics of LPD- IS. The characteristics are intended as a basis for requirement specifications in the development of LDP-IS. The framework is a construction emerging from Information Systems theory in combination with contemporary archival theory. The framework is formed as a ladder of decreasing substitutionality. The Information Continuum Model is at the foundation and least substitutional level. The Records Continuum Model constitutes a theoretical framework at the next level. At the level below that, the OAIS Reference Model is placed as a conceptual framework; it is used for talking about components of the preservation system. At the four lowest levels is Model Driven Architecture (MDA), which contains components prone to substitution. The concept of Long-term Digital Preservation Information Systems, LDP-IS, is a general overview of information systems used for preservation of digitally recorded information in the long term. LDP-IS, due to its Information Continuum foundation that kernels the continuing value of information, ensures that social systems will be reproduced as memory tracks of human activities in the future. The characteristics of LDP-IS are divided into meta-principles, general principles and desirable features. Meta-principles can be characterised as top wishes within the preservation community. The meta-principles uncovered in the research are automation (of activities performed by hand), ruling (setting up preservation policies) and preservation planning (a key concept in preservation). General characteristics found are documentation (capturing information about the material and the processes), linkability (building navigable structures across the material), substitutionality (refining the system by replacing system processes and modules), and diversification (creating different ways of using information). One desirable feature was found: learning (introducing systemic intelligence into the system)

    Normative evaluation of community projects: a multimodal systems approach2004Inngår i: Systemic Practice and Action Research, ISSN 1094-429X, E-ISSN 1573-9295, Vol. 17, nr 2, s. 83-102Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper introduces an evaluation method for community projects based on the multimodal systems approach. The method differs from the common mechanistic approach to evaluation in four ways. Firstly, it uses the long-term life (viability) of a community as the ultimate criteria of evaluation. Secondly, it is normative; that is, it focuses on the responsibility of people to their own community and for managing their own lives. Thirdly, it is dynamic; it identifies factors that threaten a community and examines their dynamic link and long-term impact on the community. Fourthly, it evaluates the adequacy of a community activity (good practice) to help ensure its long-term viability. The method is illustrated with a European Union sponsored project.

    What the prophet and the philosopher told their nations: a multi-modal systems view of norms and civilisation1996Inngår i: World Futures: Journal of General Evolution, ISSN 0260-4027, E-ISSN 1556-1844, Vol. 47, nr 1, s. 53-67Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It is argued that contemporary systems scientists should follow the practices of ancient philosophers & prophets & determine how modern social institutions can be reconstructed. Herman Dooyeweerd's (1958, 1976) classification of modalities is employed to establish a multimodal systems map that includes an epistemic modality; this system is applied to the study of decadence in modern society. It is contended that the repudiation of the normative order of the modalities by science has effected an intellectual void; moreover, by rendering science subservient to industrial interests through the distribution of funding, national governments have effectively industrialized scientific research. A review of the ancient philosophies/prophecies of Augustine, Jeremiah, & Socrates emphasizes their collective placement of righteousness as embodied within social justice; further, since ancient philosophers privileged devotion to God, the secularization of the modern scientific community is lamented. It is concluded that a multimodal systems approach can replace modalities within their respective proper locations & reestablish their identities & normative orders, thus promoting humanism rather than utilitarianism

    Where there is no vision the people perish: ethical vision and community sustainability2005Inngår i: Systems research and behavioral science, ISSN 1092-7026, E-ISSN 1099-1743, Vol. 22, nr 3, s. 233-247Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper supports the inclusion of Christianity in the European constitution. It does this by analysing the role that an ethical vision plays in sustaining a community and the impact on other critical factors such as ethics, work, management, social structure and education that ensues when vision is undermined. It examines in particular the contribution that the Christian vision has made to communities in the past and the systemic role it can play in ensuring their long-term viability today. The study applies a multi-modal systems framework to analyse the links between the vision and these critical factors and projects that may unfold in communities once they lose their vision

    Abstract [en]

    This article is based on my presidential address to the Swedish Operational Research Society 1996 Conference. It starts with a statement affirming the critical need to incorporate virtues and norms in the management and operation of our institutions. With the help of multimodal systems thinking and Stafford Beer's Viable Systems Model, it builds a framework that allows the transfer of such things as faith, love, and wisdom into the operation of our social systems and their management. The article concludes with the placing of operational research and management theory within this framework and with a challenge to all operational researchers to work for new modeling techniques that will contribute to a more virtuous and humane society.

    Abstract [en]

    The object of this inquiry is threefold. Firstly, it reviews the historical process through which science has become depersonalised and secularised. Secondly, it investigates the normative consequences of this. Thirdly, it proposes a way to integrate thought as part of our person and as part of our experience of God and the universe.

    A normative application of multi-modal systems thinking to a non-viable social system2001Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This research evaluates how multi-modal systems thinking, a normative approach to systems science, answers to the theoretical, practical and ethical demands emerging from research in sustainability and to systems scientists concerned with the norms of life and ethics. The thesis starts with a broad survey of sustainability literature and concludes that this multi-modal systems methodology, which has emerged during the last decade, has a significant contribution to make. This systems approach was applied to Rosvik, a small village in northern Sweden, which is undergoing instability and threats to its longterm viability. In particular, the multi-modal systems method and the software package, SmCube, especially developed to apply this method, proved useful tools. They pointed to issues and identified threats to the village that corresponded closely to those identified in the sustainability literature.

    Multi-modal systems method: The impact of normative factors on community viability2001Inngår i: Systems research and behavioral science, ISSN 1092-7026, E-ISSN 1099-1743, Vol. 18, nr 2, s. 171-180Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This is an analysis of viability in a small village in northern Sweden and a contribution to testing the multi-modal systems method (MMSM). With the aid of the method, factors important to a village's life were selected and relationships between them analysed, to see if they promoted or threatened viability. Relationships are characteristic of a small community and it is argued that viability is best understood by examining relationships. MMSM proved a useful tool for studying relationships between the factors selected, between various modalities of community life, and between community groups.

    Measuring trust in online social networks: the effects of network parameters on the level of trust in trust games with incomplete information2012Inngår i: WEBIST 2012: Proceedings of the 8th International Conference on Web Information Systems and Technologies, Porto, Portugal, 18 - 21 April, 2012 / [ed] Karl-Heinz Krempels; José Cordeiro, SciTePress, 2012, s. 531-539Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The most currently popular method for assessing trust in online social networks is Trust Game. The major studies in this area have established results formed into hypotheses for the effects of a number of network parameters on the extent to which individuals would place trust on each other. However, hypotheses for the effects of a few number of network parameters, such as Indegree, are not deducible since the restrictive game-theoretic assumptions that are imposed into the model do not let any such evidence available. To relax the game-theoretic assumptions, we develop a model for games with incomplete information, based on a game-theoretic model developed by Buskens (1998), and conduct a series of computer simulation of a model of Iterated Heterogeneous Trust Games (IHTG). We compare the results with those of Buskens’ (1998) model and introduce Link-Strength as a new network parameter to investigate. Our results show a positive effect of both Indegree and Link-strength on the level of trust in a noisy environment. In addition, we come to a conclusion that current models can be fooled by the existing noise in the context of information transmission, such as inactive users in our case.

    Administration of Digital Preservation Services in the Cloud Over Time: Design Issues and Challenges for Organizations2014Inngår i: The Proceedings of the 2nd International Conference on Cloud Security Management / [ed] Barbara Endicott-Popovsky, Reading, UK: Academic Conferences and Publishing International Ltd , 2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In organizations, information systems produce increasing amounts of digital information that needs to be preserved. Simultaneously, human intervention in preservation activities needs to be minimized, due to scarce resources available for preservation. Thus, digital preservation services need to be integrated with other organizational information systems as seamlessly as possible, and preservation activities need to be maximally automated. Selection of adequate cloud-based preservation services poses yet another set of challenges for reaching the seamless integration and automation. Two sources of challenges relate to administrating integrated digital preservation and information systems. Firstly, information systems change over time. Secondly, digital preservation services change over time. This paper contributes by identifying and analyzing scenarios and design issues of administering digital preservation in connection to the changes in information systems and preservation services over time. We also suggest seven generic tasks of the “preservation administration” component, which are needed between digital preservation services and information systems and discuss about the choices of locating the operative responsibilities and middleware.

    Abstract [en]

    The introduction of information technology in society during the last 30 years has brought mixed results. There is evidence that the benefits to society may not outweigh the detrimental effects that have followed this technology. This is partly because its inclusion in the affairs of humanity has been guided by a mechanical and utilitarian world view that considers humanity as a mean of production and subject to industrial goals. This paper reverses this subjection and presents a framework that integrates information systems design with an overall system design approach and which makes machines the servant of humanity. The design approach is based on a combination of Dooyeweerd's theory of modalities and general systems theory

    Inherent problems in cooperative planning for future access to information2013Inngår i: Norsk konferanse for organisasjoners bruk av informasjonsteknologi, NOKOBIT 2013: Universitetet i Stavanger, 18-20 november 2013 / [ed] Terje Fallmyr, Trondheim: Tapir Akademisk Forlag, 2013, Vol. 2013Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Successfully preserving information for the future draws upon multiple domains of knowledge, specifically knowledge about effects of technological and social change. The preservation process should accommodate for these effects in order to provide future access to the preserved information. If information production and information preservation occur in different organizations, such as when an organization uses external preservation services, special attention has to be given to the planning of the preservation process. Studies in the project ENSURE (Enabling kNowledge Sustainability Usability and Recovery for Economic value) indicate that the preservation planning is a joint effort drawing upon distinct knowledge that each organization have – knowledge about the information and knowledge about the preservation process. We describe some inherent problems emanating from cooperatively planning how to preserve information.

    Adversarial deep learning against intrusion detection classifiers2017Inngår i: CEUR Workshop Proceedings / [ed] Kott A.,Pechoucek M., CEUR-WS , 2017, Vol. 2057, s. 35-48Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Traditional approaches in network intrusion detection follow a signature-based approach, however the use of anomaly detection approaches and machine learning techniques have been studied heavily for the past twenty years. The continuous change in the way attacks are appearing, the volume of attacks, as well as the improvements in the big data analytics space, make machine learning approaches more alluringthan ever. The intention of this paper is to show that using machine learning in the intrusion detection domain should be accompanied with an evaluation of its robustness against adversaries. Several adversarial techniques have emerged lately from the deep learning research, largely in the area of image classification. These techniques are based on the idea of introducing small changes in the original input data in order to make a machine learning model to misclassify it. This paper follows a big data analytics methodology and explores adversarial machine learning techniques that have emerged from the deep learning domain, against machine learning classifiers used for network intrusion detection. We look at several well-known classifiers and study their performance under attack over several metrics, such as accuracy, F1-score and receiver operating characteristic. The approach used assumes no knowledge of the original classifier and examines both general and targeted misclassification. The results showthat using relatively simple methods for generating adversarial samples it is possible to lower the detection accuracy of intrusion detection classifiers as much as 27%. Performance degradation is achieved using a methodology that is simpler than previous approaches and it requires only 6.14% change between the original and the adversarial sample, making it a candidate for a practical adversarial approach.

    Data Analytics in Service Systems: Exploring Analytics-based Value Co-creation2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    With the increasing pervasiveness of ICT in our everyday practices, we are turning into moving ‘data generators’. Service systems, among many organizational configurations, are striving to create value from the vast data generated by utilizing data analytics, which in turn informs the design and delivery of their innovative services. While data analytics is perceived to generate high value to organizations, we know little about how this process unfolds, what values can be captured, and if they change on different loci of value within service systems. To address these gaps, this paper outlines a research study to explore analytics-driven service systems using a sociomaterial theoretical lens. The study will follow a qualitative research approach, drawing on empirical data from a smart city context.

    Abstract [en]

    Service innovation is attracting attention with the expanding service industries and economies. Accompanied by major developments in ICT and sensory and digital technologies, the interest in digital service innovation (DSI), both from academia and industry, is increasing. Digitization and the accompanying technological advancements are leading to phenomena that call for extensive research in relation to service innovation; one of which is big data analytics (BDA). In this paper, we review the DSI literature and explore how BDA can contribute along the different dimensions of DSI. The ex post literature suffers from the lack of such studies. Accordingly, we suggest a research agenda for BDA-enabled DSI, motivated by emerging research gaps, as well as opportunities and guiding research questions. It is expected that such research agenda will contribute to shape an ex ante research efforts in an attempt to advance the state-of-the-art in BDA-enabled DSI.

    Data science: developing theoretical contributions in information systems via text analytics2020Inngår i: Journal of Big Data, E-ISSN 2196-1115, Vol. 7, artikkel-id 7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Scholars have been increasingly calling for innovative research in the organizational sciences in general, and the information systems (IS) field in specific, one that breaks from the dominance of gap-spotting and specific methodical confinements. Hence, pushing the boundaries of information systems is needed, and one way to do so is by relying more on data and less on a priori theory. Data, being considered one of the most important resources in research, and society at large, requires the application of scientific methods to extract valuable knowledge towards theoretical development. However, the nature of knowledge varies from a scientific discipline to another, and the views on data science (DS) studies are substantially diverse. These views vary from being seen as a new scientific (fourth) paradigm, to an extension of existing paradigms with new tools and methods, to a phenomenon or object of study. In this paper, we review these perspectives and expand on the view of data science as a methodology for scientific inquiry. Motivated by the IS discipline’s history and accumulated knowledge in using DS methods for understanding organizational and societal phenomena, IS theory and theoretical contributions are given particular attention as the key outcome of adopting such methodology. Exemplar studies are analyzed to show how rigor can be achieved, and an illustrative example using text analytics to study digital innovation is provided to guide researchers.

    Trajectory data analysis in support of understanding movement patterns: A data mining approach2012Inngår i: 18th Americas conference on information systems 2012: Seattle, Washington, USA, 9-12 August 2012., Curran Associates, Inc., 2012, s. 1695-1702Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Recent developments in wireless technology, mobility and networking infrastructures increased the amounts of data being captured every second. Data captured from the digital traces of moving objects and devices is called trajectory data. With the increasing volume of spatiotemporal trajectories, constructive and meaningful knowledge needs to be extracted. In this paper, a conceptual framework is proposed to apply data mining techniques on trajectories and semantically enrich the extracted patterns. A design science research approach is followed, where the framework is tested and evaluated using a prototypical instantiation, built to support decisions in the context of the Egyptian tourism industry. By applying association rule mining, the revealed time-stamped frequently visited regions of interest (ROI) patterns show that specific semantic annotations are required at early stages in the process and on lower levels of detail, refuting the presumption of cross-application usable patterns

    Abstract [en]

    This study analyses the content of the International Journal of Wine Business Research (IJWBR) and gives editors, reviewers, authors and practitioners an overview over the journal’s development over 26 years. The articles published in the journal since its inception in 1989 till 2014, inclusive, were analysed in two time frames. The first time frame covers 1989–2006 as the International Journal of Wine Marketing (IJWM), while the second time frame covers 2007–2014 as IJWBR, the new name under which the journal relaunched. All types of articles are included in the analysis with the exception of editorials, guest editorials and research notes. Five main themes are addressed: the nature of authorship, the most prolific and influential authors, characteristics of the manuscripts, regional distribution of the wine’s region-of-origin and focal markets, and the most common research themes.

    The content analysis of this journal sheds light on how the style of the journal has evolved since its inception in 1989 onto the second time frame. The types of articles and methods used have been consistent in the early issues (1989–2006). However, since 2007 the journal has welcomed more academic and quantitative articles. The change motivated new authors to write longer articles, collaborate more and use more references, tables and figures. As a result, the journal’s impact has increased significantly. In addition, empirical studies published in the journal indicated an increase in the publications covering the Americas as both regions of origin and focal markets, as compared to other regions. This is the first time a content analysis has been carried out for IJWBR. The objective is to help authors identifying new and interesting research areas as well as to give editors and reviewers insight into the style and areas explored since the journal’s inception. By using software tools for data collection and analysis, the study is bound to the limitations inherent from these tools.

    Crew intelligence systems for digital objects preservation2009Inngår i: Proceedings of the Symposium 2nd Swarm Intelligence Algorithms and Applications Symposium (SIAAS-09): A symposium at the AISB 2009 Convention (6-9 April 2009) Heriot-Watt University, Edinburgh, Scotland, Society for the Study of Artificial Intelligence and the Simulation of Behaviour , 2009, s. 23-30Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Crew Intelligence Systems is a family of very simple algorithms for different classes of complex optimization problems in static and dynamic environments by means of reactive multiagent systems. Crew Intelligence systems are loosely inspired from the behavior shown by a staff of bartenders when serving drinks to customers in a bar or pub. In this paper we improve them by letting the bartenders also call (shout) for help, and we adapt them to Digital Objects Preservation, where agents explore file systems looking for victims, digitals objects that need change of format, or any other transformation to be preserved. When they find someone they “shout” so that agent mates can hear it. The louder the shout, the most important or urgent the finding. Louder shouts can also refer to closeness. We perform several experiments to show that this system works very scalably, showing that heterogeneous teams of agents outperform homogeneous ones over a wide range of task complexity. Finally, a properly designed combination of heterogeneous agents is more scalable when confronted with uncertain maps of digital objects to be preserved.

    Impact of cognitive absorption on facebook on students' achievement2012Inngår i: CyberPsychology, Behavior and Social Networking, ISSN 2152-2715, E-ISSN 2152-2723, Vol. 15, nr 6, s. 296-303Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In the great expansion of the social networking activity, young people are the main users whose choices have vast influence. This study uses the flow theory to gauge the impact of Facebook usage on Tunisian students' achievements, with the presumption that the high usage level might reduce students' scholar achievements. The research design suggests that this impact would vary among students with different interests for the university and multitasking capabilities. Facebook usage would develop students' satisfaction with friends and family, which could enhance their academic performance. Analyses from 161 Tunisian students show that Facebook usage does not affect significantly students' academic performance and their satisfaction with the family, whereas it decreases their actual satisfaction with friends. Yet, a high level of satisfaction of the student with his family continues to enhance his academic performance. Overall, though, Facebook usage appears to do not have a significant effect on undergraduate students' academic performance. However, this interdependency is significantly moderated by the student's interest for the university and his multitasking capabilities. Students with multitasking skills and students with initial interest for the university might experience a positive effect of Facebook usage on their studies, as they keep control over their activity and make it a beneficial leisure activity. However, students who do not have these characteristics tend to not have any significant effect. Results help to understand the psychological attitude and consequent behavior of the youths on this platform. Implications, limitations, and further research directions are offered.

    Impacts of Facebook hedonic usage on students’ academic achievement: the role of culture and personality characteristics2012Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The largest online social network in the world, Facebook continues to prompt debate about users’ behaviors. The effects of online activities on themselves and their interactions with others have been discussed extensively. In particular, students are a main class of Facebook users who spend long hours on the social network, which has worried parents and educational authorities about their academic performance. The students themselves argue that their presence on Facebook, as a leisure activity, does not hinder their academic efforts, though some evidence suggests that their grades decline after they join Facebook.To address these questions, I have designed five separate, complementary studies, supported by a conceptual research model derived from flow theory, capacity theory, and the “very rich” model of information system usage. These studies measure actual and perceived impacts and compare them, both in a single cultural context and across widely divergent cultures. Specifically, the first study assessed actual impacts in Tunisia; the second measured the perceived impacts in Sweden. In a third study, I analyzed differences between perceived and actual impacts among undergraduate students from the United States. Finally, I performed two comparative studies to investigate the role of culture in moderating perceptions of the effect of time spent and cognitive immersion on Facebook (Sweden and the United States) and then regulating the actual effect of such usage (Tunisia and the United States), in consideration of the level of conscientiousness and extroversion of students from each country.The results show that students’ presence on and cognitive absorption in Facebook does not immediately threaten their academic performance. Their cultural background affects perceptions and thus behaviors. Personality characteristics, such as personality traits, trust in people, self-regulation, and multitasking skills, also significantly moderate the effects. A student’s interest in school and his performance goal orientation represent strong determinants of academic achievement. Finally, satisfaction with life is a key difference between cultures; it reflects various aspects of a person’s life. Thus, it was perceived differently between Swedes and U.S. students; it emerges as a key concept to consider in analyzing the effects of a leisure activity, such as Facebook, on individuals and their performance.

    Access to public information in governmental agencies and archives – main challenges: an analysis of the Estonian, Icelandic and Swedish legal frameworks, with focus on main challenges for developing governmental e-services2011Rapport (Annet vitenskapelig)
    Abstract [en]

    The ongoing development of e-services gains much interest from many groups in the society, ranging from citizens and organizations to research communities. Initiatives are taken both from separate private persons to authorities themselves. Looking at the UN e-government survey 20101 we find Sweden (ranked 12) and Estonia (ranked 20) among the top20 in the e-government development index, and when it comes to the e-participation index only Estonia is found, this time ranked 9. Thus, Estonia2 has come furthest with involvement of citizens, while Sweden3 and Iceland4 is not as mature. Also the cultural heritage sector would benefit by being able to offer e-services that are developed from the citizen’s focus. Thus, the main questions are e.g.; what public information is of interest to citizens? And how would they like to access this information? What kind/s of service/s would they prefer? The APIS project set out to investigate what e-services could be developed, that increases the accessibility and use of public information that resides in governmental agencies and archives.

    Gender mainstreaming - sorting out what?2004Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This paper discusses the strategy of gender mainstreaming which is adopted by the European Union and the Swedish Government in order to increase gender equality in the entire society. Gender mainstreaming and its goal - gender equality - are not easily understood. In this paper I will discuss different interpretations of the concept gender mainstreaming within the area of education. Since the intention with gender mainstreaming is that a gender perspective should permeate all levels in society, this indicates that the area of Information Technology should be embraced by the strategy as well. Building information structures involve classification and categorization. Thus, I will also discuss what implications gender mainstreaming hold for the future Information Technology society for all. The research draws on empirical research conducted during 2003-2004 and is based on documentary analyses and semi-structured interviews with policy makers and teachers. The material has been analysed by discourse analysis.

    Information technology, archives and archivists: an interacting trinity for long-term digital preservation2007Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis revolves around archivists' current situation, and the fact that information technologies nowadays are tools that creates digital official documents which must be preserved for long-term. I have studied how the technologies affects and eventually changes archivists work practice and situation, and what recommendations that can be identified, in order to make sure that archivists' work practice runs smoothly in the future. That is, the research involves how archivists experience their situation, how they look at information technologies and long-term digital preservation, and also which areas they mainly focuses on, or feels most concerned about. My research consists of participatory observations conducted while following an archivist a couple of times each month for more than a year, data gathering at an archival conference for county council archivists, a future workshop and finally a focus group interview with archivists working at an existing e-archive. During my research I have focused on things or phenomena that engage archivists and causes problems in their daily work practice. These phenomena I have divided into the following themes: work practice, cooperation and communication, organisation, professional roles and competence, resources, attitudes, information technology, and finally laws and regulations. My research shows that there is lack of knowledge in archival matters among other professional groups in the organisations, which makes the archivists work practice unwieldy. Archivists must constantly remind, educate and support other personnel involved in archiving. The archivists express that they are ascribed low status in their organisations and that archiving is neglected and low-prioritised - something that is conducted when other work task are done. Concerning long-term digital preservation the archivists ask for The Solution, since they lack knowledge in information technologies. Moreover, archivists express that there are lack of knowledge in archiving, mainly among management and IT-personnel. Meanwhile archivists work rather alone, with little or none cooperation with IT-personnel. IT-departments are said to run their own race and archivists get not enough support from management. Cooperation and communication seem to be non-existing among these groups. Today many organisations do not have any strategies for long-term digital preservation. Often it is the archivists that are regarded to be the problem owner of this issue. In connection to this I have found that archivists are unsure of their own role and mission, and what competence they should possess. They claim that archivists are mainly connected with paper, and thereby they are shut out from long-term digital preservation issues. Moreover, archivists are not involved when e.g. new computer based systems are to be designed or implemented. Because of this archivists cannot influence the archival creation from the beginning. Lack of resources is also expressed by archivists, and involves lack of time, finances, personnel and competence. Moreover, information technology has caused that the respect for laws and regulations are declining, and digital documents are not regarded as official. Conclusions drawn are that there is lack of understanding of archivists work practice among other professional groups in the organisations. Archivists are expected to take care of and preserve information that exists in technologies with which they are not comfortable. Organisations has left the responsibility for long-term digital preservation to archivists alone, since the organisations have not succeeded in establishing cooperation and communication among concerned professional groups, especially archivists, IT personnel and management. This could seem as a paradox, since archivists are not involved when computer based systems are at stake, systems that generates the official documents that the organisation is obliged to

    On organizing for digital preservation2009Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Information technology facilitates production and spreading of information, as well as enables the transformation towards e-government and e-services. As a consequence, numerous official documents are born digital, i.e. no paper originals exist. Although there is a lot of ongoing research in digital preservation and digital curation, how digital material is to be preserved for the long-term is still an issue. In the area most research concerns technological aspects. However, the point of departure for this thesis is that the challenge of long-term digital preservation also demands human, social and organizing considerations. This is explored on the basis of how people involved in digital preservation understand, experience and interpret the current situation. The methodological approaches for this thesis are found in interpretative and feminist technoscience perspectives. The Research is also influenced by design perspectives, such as participatory design and systems design, where the latter involves Viable System theories. The empirical material was gathered through participant observations, brainstorming, future workshops, and individual and group interviews. Additional contributions to this study consists of recurrent discussions with systems developers at the Long-term Digital Preservation Centre. The empirical material has been analyzed through ongoing interpretations, discourse analysis, by mapping actors and agendas, and also by themes that have arisen during the research. The research was initiated by exploring the current situation as understood, experienced and interpreted by archivists. Findings from the initial studies suggested that cooperation and communication around digital preservation were not functioning well in many organizations today. Also, responsibility questions were unclear, such as which functions and roles are responsible for digital preservation and what kinds of responsibility are then involved. These questions constituted the continuation of the research and additional studies were made, now from organizing perspectives. A governmental authority has contributed with a ‘best practice' case, which is demonstrated through the lenses of the Viable System Model (VSM) and its underlying theories. The VSM is in this research used as a plan for how to organize digital preservation. However, a plan needs recurrent revisions since people (and technologies) do not always act as supposed. Rather the actions tend to be based on available understandings and knowledges, i.e. situated actions. These in turn, can be viewed as related to ongoing reconfigurations of the world - agency. The main findings are that in order to organize for digital preservation, archival creating organizations should pay attention to humans, technology and the overall organization, and the interplay between these parts. There should be efforts for facilitating collaboration and communication among staff. Identification of preservation processes and where they take place in the organization is important. This can be the foundation for clarification of tasks and responsibilities, where the responsibilities are threefold; the practical, the technological and the strategic. When working on a plan for organizing digital preservation, it is also preferable to involve the staff concerned.Moreover, information technology makes possible the accessibility of the digital material in a totally different way than paper, or analogue archival material. This makes it necessary to modify the view of archives. Hence, a new view of archives is provided; as a more active and living part of the entire information assets held by an organization.
