IT-supported Knowledge Repositories : Increasing their Usefulness by Supporting Knowledge Capture
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- 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).

Decision Making with Hierarchical Credal Sets
- 2014
-
Ingår i: Information Processing and Management of Uncertainty in Knowledge-Based Systems. - Cham : Springer. - 9783319088518 - 9783319088525 ; , s. 456-465

Konferensbidrag (refereegranskat)abstract
- We elaborate on hierarchical credal sets, which are sets of probability mass functions paired with second-order distributions. A new criterion to make decisions based on these models is proposed. This is achieved by sampling from the set of mass functions and considering the Kullback-Leibler divergence from the weighted center of mass of the set. We evaluate this criterion in a simple classification scenario: the results show performance improvements when compared to a credal classifier where the second-order distribution is not taken into account.

Att leda i en komplex organisation : Utmaningar och nya perspektiv för chefer i offentlig verksamhet
- 2018
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Några av Sveriges främsta ledarskapsforskare ger i denna bok ökad kunskap för att förstå, styra och hantera organisatorisk komplexitet. Chefer i komplexa organisationer behöver hantera osäkerhet och överraskande händelseförlopp för att organisationen ska fungera väl. Det kräver att cheferna har förståelse för de förutsättningar som gäller i sådana organisationer, till exempel att beslut samproduceras i och utanför ledningsgrupper, att professionsföreträdare har ett betydande inflytande och att konkurrerande normsystem är vanliga. Ett annat särdrag är hur emotionellt krävande chefsarbetet är, med tryck inte bara från medarbetare utan även från anhöriga, brukare, den breda allmänheten, granskningsaktörer och media. Samtidigt kännetecknas komplexa organisationer av flertalet system som syftar till att reducera osäkerhet och styrproblematik, men som också i sig ställer särskilda krav på chefsarbetet.Kapitlen i denna antologi är fristående och ger ett antal kompletterande bilder av komplexitet – dess problematiker och ibland förslag på lösningar. De många exemplen kommer nästan uteslutande från offentlig sektor, eftersom den vanligen kännetecknas av omfattande komplexitet, men innehållet är relevant för alla komplexa organisationer.Boken är skriven för utbildningar i ledarskap på högskolenivå, för organisationsledningar, verksamhetsnära chefer och specialister i chefsfunktioner.

Development Process Knowledge Transfer through Method Adaptation, Implementation, and Use
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Information Systems Engineering (ISE) is an interdisciplinary approach to enable the realisation of successful information systems in a broad sense. ISE comprises a number of areas of expertise that must be integrated and managed in order to build information systems. Since ISE is becoming progressively more complex there is an increasing need to codify and manage knowledge within and about the ISE process. From a knowledge perspective the different model types created in an ISE project are examples of codified knowledge about the future system. The descriptions of how work should proceed are examples of codified knowledge of the process of creating the system. In summary, one of the main concerns in the ISE process is to manage the substantial amount of knowledge associated with the process as such as well as with the target domain of the actual development project and the developed software. In the thesis I recognise three areas of knowledge in ISE: development process knowledge, target domain knowledge, and software knowledge. Furthermore, I use a set of knowledge perspectives in order to describe and analyse ISE from a knowledge perspective. Finally, I introduce three aspects: organisation, artefact, and individual in order to be able to discuss and analyse how methods are actually used in organisations and how they affect the work situation. The results are presented in the form of a framework for knowledge transfer in ISE that comprises the knowledge perspective, the knowledge area, and the aspect of knowledge transfer. The framework is thus used to analyse the results from the six papers enclosed in the thesis. The results also comprise an empirical characterisation of a method in use which is based on data collected during an ethnographical study. Finally the results are made concrete in the form of a pattern collection for method introduction and method use.

Konferensbidrag (refereegranskat)abstract
- Large or lengthy disruptions to the card payment system are threats that can cause crisis in society, especially in countries where other payment options are scarce. This paper presents a study that provides suggestions on how to improve a simulation game used to increase societal resilience to payment system disruptions. Questionnaires and interviews have been used to investigate how 16 participant in crisis exercises experience realism, relevance and validity in such exercises. Suggestions on how to improve the simulation game are provided, such as improvements to the graphical interface and introducing supporting roles from the exercise management.

Factors influencing Internet usage in older adults (65 years and above) living in rural and urban Sweden
- 2015
-
Ingår i: Health Informatics Journal. - : Sage Publications. - 1460-4582 .- 1741-2811. ; 21:3, s. 237-249
-
Tidskriftsartikel (refereegranskat)abstract
- Older adults living in rural and urban areas have shown to distinguish themselves in technology adoption; a clearer profile of their Internet use is important in order to provide better technological and health-care solutions. Older adults' Internet use was investigated across large to midsize cities and rural Sweden. The sample consisted of 7181 older adults ranging from 59 to 100 years old. Internet use was investigated with age, education, gender, household economy, cognition, living alone/or with someone and rural/urban living. Logistic regression was used. Those living in rural areas used the Internet less than their urban counterparts. Being younger and higher educated influenced Internet use; for older urban adults, these factors as well as living with someone and having good cognitive functioning were influential. Solutions are needed to avoid the exclusion of some older adults by a society that is today being shaped by the Internet.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Maintaining good cognitive function with aging may be aided by technology such as computers, tablets, and their applications. Little research so far has investigated whether internet use helps to maintain cognitive function over time.Design: Two population-based studies with a longitudinal design from 2001/2003 (T1) to 2007/2010 (T2).Setting: Sweden and the Netherlands.Participants: Older adults aged 66 years and above from the Swedish National Study on Ageing and Care (N = 2,564) and from the Longitudinal Aging Study Amsterdam (N = 683).Measurements: Internet use was self-reported. Using the scores from the Mini-Mental State Examination (MMSE) from T1 and T2, both a difference score and a significant change index was calculated. Linear and logistic regression analysis were performed with difference score and significant change index, respectively, as the dependent variable and internet use as the independent variable, and adjusted for sex, education, age, living situation, and functional limitations. Using a meta-analytic approach, summary coefficients were calculated across both studies.Results: Internet use at baseline was 26.4% in Sweden and 13.3% in the Netherlands. Significant cognitive decline over six years amounted to 9.2% in Sweden and 17.0% in the Netherlands. Considering the difference score, the summary linear regression coefficient for internet use was-0.32 (95% CI:-0.62,-0.02). Considering the significant change index, the summary odds ratio for internet use was 0.54 (95% CI: 0.37, 0.78).Conclusions: The results suggest that internet use might play a role in maintaining cognitive functioning. Further research into the specific activities that older adults are doing on the internet may shine light on this issue.

Overuse of methylphenidate : an analysis of Swedish pharmacy dispensing data
- 2018
-
Ingår i: Clinical Epidemiology. - : Dove Press. - 1179-1349 .- 1179-1349. ; 10, s. 1657-1665

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To identify overuse of methylphenidate and to investigate patterns of overuse in relation to sociodemographic and clinical characteristics. Patients and methods: Swedish national, pharmacy dispensing data were analyzed for all 56,922 individuals aged 6-79 years, who filled a methylphenidate prescription between 2010 and 2011. Overuse was defined as having above 150% days covered by the dispensed amount during 365 days from the first prescription fill, assuming use at the maximum recommended daily dose. Results: In total, 4,304 individuals (7.6% of the methylphenidate users) were categorized as overusers. The risk of overuse increased with age (OR for 46-65 years vs 6-12 years 17.5, 95% CI 14.3-21.3), and was higher in men (OR 1.4, 95% CI 1.3-1.5) and individuals with low income (OR 1.1, 95% CI 1.0-1.2), as well as in individuals with an attention deficit hyperactivity disorder (ADHD) diagnosis (OR 1.4, 95% CI 1.3-1.6), health care visits (OR 1.3, 95% CI 1.2-1.4), previous ADHD medication use (OR 2.6, 95% CI 2.4-2.8), and previous diagnosis of mental and behavioral disorders due to psychoactive substance use (OR 2.1 95% CI 2.0-2.3). Conclusion: Among individuals using methylphenidate in Sweden, 7.6% receive amounts that are larger than what they should have a medical need for, assuming that they were using the maximum recommended daily dose 365 days per year. Notably, the prevalence of overuse was associated with previous diagnosis of alcohol and drug misuse. The prevalence was also positively associated with higher age and previous use of ADHD medication. These findings may point toward a link between exposure time and overuse. However, future studies with long-term data are needed to investigate this.
