The aim of this position paper is to argue for the suitability of an institutional perspective in IS/IT (Information Systems/Information Technology) security research. Institutional theory, including some of its central concepts, is presented, along with examples of how it has been used in information systems research. A discussion of how the theory could(More)
Information security education and training needs to be valued and assessed from various perspectives. This study presents two differing viewpoints from which such an evaluation can be perceived – those of the individual and the organisation. Some sorts of profits are sought after by each of the two, although this is expressed and hence valued differently(More)
This paper presents the findings of an empirical study of certification auditors’ and information security consultants’ experiences and insights concerning the implementation and certification of information security management systems. Using an action research strategy and a grounded theory research method, the study describes these particular experiences(More)
INTRODUCTION Warfarin treatment discontinuation is significant among patients with atrial fibrillation (AF). For AF patients with stroke a warfarin persistence rate of 0.45 after 2years has previously been reported. No consistent predictors for discontinuation have been established. AIMS Evaluation of warfarin persistence and variables associated with(More)
IMPORTANCE Vitamin K antagonist (eg, warfarin) use is nowadays challenged by the non-vitamin K antagonist oral anticoagulants (NOACs) for stroke prevention in atrial fibrillation (AF). NOAC studies were based on comparisons with warfarin arms with times in therapeutic range (TTRs) of 55.2% to 64.9%, making the results less credible in health care systems(More)
BACKGROUND Warfarin treatment in Sweden holds a high standard with time in therapeutic range (TTR) over 75%. Internationally, specialized anticoagulation clinics (ACC) have shown higher TTR compared to primary health care centres (PHCC). OBJECTIVES To compare warfarin treatment quality in Sweden for ACC versus PHCC, thereby clarifying whether(More)
This thesis is concerned with issues relating to the management of information security in organisations, motivated by the need for cost-efficient information security. It is based on the assumption that: in order to achieve cost-efficient information security, the point of departure must be knowledge about the empirical reality in which the management of(More)
