Aortic rupture after spinal correction for scoliosis in the presence of a thoracic stent graft
- 2010
-
In: Journal of Vascular Surgery. - : Elsevier BV. - 0741-5214 .- 1097-6809. ; 52:6, s. 1653-1657

Journal article (peer-reviewed)abstract
- Corrective surgery for scoliosis often results in a lengthening of the spinal column and relative change of the position of the adjacent anatomical structures such as the aorta. The extent of these anatomical changes could be affected by the presence of a rigid aortic stent graft in the descending thoracic aorta. We present a case of aortic rupture after spinal correction for scoliosis in a 56-year-old female with a thoracic aortic stent graft. Extensive elongation of the aorta with concentration of the stress forces at the lower margin of the stent graft resulted in a weakening of the aortic wall and subsequent rupture.

Angry Voices from the Past and Present : Effects on Adults' and Children's Earwitness Memory
- 2013
-
In: Journal of Investigative Psychology and Offender Profiling. - : John Wiley & Sons. - 1544-4759 .- 1544-4767. ; 10:1, s. 57-70
-
Journal article (peer-reviewed)abstract
- The major aim was to examine the effect of the perpetrator’s tone of voice and time delay on voice recognition. In addition, the effect of two types of voice description interviews intended to strengthen voice encoding was tested. Both 11- to 13-year-olds (n = 160) and adults (n = 148) heard an unfamiliar voice for 40 s. The perpetrator either spoke in a normal tone at encoding and in the lineup (congruent), or in an angry tone at encoding and a normal tone in the lineup (incongruent). Witnesses were then interviewed about the voice with global questions or by rating voice characteristics. Half of the witnesses were presented with a lineup shortly after the interview (immediate) and the others after 2 weeks (delayed). Children tested immediately made significantly more correct identifications. This was not the case for adults. (In)congruency between tone of voice and interview type did not significantly affect voice recognition. Witnesses in the congruent–immediate condition performed the best. However, only 25% of the children and 19% of the adults made correct identifications. Poor identification accuracy and the fact that the majority of witnesses believed they would recognise the voice later are reasons for treating voice identification evidence with great caution.

Enhancing Adults' and Children’s Earwitness Memory : Examining Three Types of Interviews
- 2013
-
In: Psychiatry, Psychology and Law. - : Taylor & Francis. - 1321-8719 .- 1934-1687. ; 20:2, s. 216-229
-
Journal article (peer-reviewed)abstract
- The aim of the study was to find ways to enhance earwitnesses’ memory for voices and content. Another aim was to evaluate an interview protocol used by the Swedish Security Service. Three different types of interviews were compared; the Cognitive Interview, the Swedish Security Service checklist, and a baseline interview. Both 11–13-year-olds (n = 119) and adults (n = 93) were exposed to an unfamiliar voice for 40 seconds and thereafter interviewed. Two weeks later, they were confronted with a seven voice line-up. The overall accuracy for correct identifications was 19.8%. No significant difference was found between the interview conditions. As for content, the results suggest that for adults, the Cognitive Interview may be beneficial for recall of a brief conversation. The checklist used by the Swedish Security Service did not have a positive effect on voice recognition, content recall or for descriptions of voices.

Overhearing the planning of a crime: Do adults outperform children as earwitnesses?
- 2011
-
In: Journal of Police and Criminal Psychology. - : Springer Science and Business Media LLC. - 0882-0783 .- 1936-6469. ; 26:2, s. 118-127
-
Journal article (peer-reviewed)abstract
- This study examined the reliability of earwitnesses using an ecologically realistic experimental set-up. A total of 282 participants, distributed over three age-groups (7–9 vs. 11–13 year olds vs. adults), were exposed to an unfamiliar voice for 40 seconds. After a two week delay, they were presented with a 7-voice lineup. Half of the participants were exposed to a target-present lineup (TP), and the other half to a target-absent lineup (TA). For both types of lineups the participants performed poorly. In the TP-condition only the 11–13-year olds (with 27% correct identifications) performed above chance level. Furthermore, in the TA-condition all age-groups showed a high willingness to make an identification (overall mean = 53%). For both groups of children, voice identification co-varied significantly with speaking rate and pitch level, as did pitch variation for the youngest children. Neither factor correlated significantly with the adults’ identifications.

Mobile phone quality vs. direct quality : How the presentation format affects earwitness identification accuracy
- 2010
-
In: The European Journal of Psychology Applied to Legal Context. - : Sociedad Española de Psicología Jurídica y Forense. - 1889-1861 .- 1989-4007. ; 2:2, s. 161-182
-
Journal article (peer-reviewed)abstract
- The present study aimed to gain insight into the effect of mobile phone quality on voice identification using an ecologically realistic design. A total of 165 participants were exposed to an unfamiliar voice, either directly recorded or mobile phone recorded, for 40 seconds. After a two week delay, they were asked to identify the target-voice in a 7 voice target-present line-up. We used a between- subjects design, where half of the subjects were exposed to a directly recorded line-up, and the other half to a mobile phone recorded line-up. Data analysis did not show any significant effect of presentation format or line-up format. These results suggest that the detrimental effect on voice recognition suggested by the poorer sound quality of mobile phone recordings is minimal. They also indicate that there is no benefit from conducting a mobile phone recorded line-up, if the voice is originally heard over a mobile phone. More research is needed, however, before definitive conclusions may be drawn. The overall accuracy for correct identifications was 12.7% which is expected by chance. Further, one particular foil attracted 54% of all false identifications. Future research should focus on explaining why earwitnesses perform so poorly and develop methods to improve identification accuracy.

Exploring Quality Challenges and the Validity of Excellence Models
- 2016
-
In: International Journal of Operations & Production Management. - 0144-3577 .- 1758-6593. ; 36:10, s. 1201-1221
-
Journal article (peer-reviewed)abstract
- Purpose: The purpose is to identify and explore important quality-related challenges facing organizations, and how current excellence models incorporate these challenges.Methodology: The article is based on a Delphi study in Swedish organizations, 49 challenges were generated and ranked according to importance. The top 10 ranked challenges were compared to the principles of four excellence models.Findings: The excellence models seem to still be relevant since their content matches many of the challenges identified. The MBNQA and the SIQ models were found to have the most comprehensive coverage, while the ISO model had limited coverage.Research Limitations/Implications: Three areas for further research were identified: 1) how QM can evolve in different contexts with varying needs in terms of adaptive and explorative capabilities, 2) the interfaces of QM and sustainability, and ways to understand how customers and stakeholders can be active contributors to improvements and 3) the roles of the owners and board of directors in QM, and how to organize and distribute responsibilities of the QM work.Practical and Social Implications: Three important challenges could be addressed in upcoming revisions of excellence models: 1) making QM a strategic issue for company owners; 2) involving customers in the improvement activities; and 3) developing processes that are robust, while still easily adaptable.Originality/Value: The Delphi study has identified upcoming challenges in the QM area based on input from 188 quality professionals.

Challenges and propositions for research in quality management
- 2018
-
In: International Journal of Production Economics. - : Elsevier B.V.. - 0925-5273 .- 1873-7579. ; 199, s. 125-137
-
Journal article (peer-reviewed)abstract
- From its inception, the field of quality management (QM) has been characterised by practice-driven development. Although QM has reached maturity as a field of research based on empirical enquiry, its practitioners still struggle to adapt QM implementations to reap their benefits. This study aims to identify their challenges to better understand how contemporary QM research addresses them. We propose approaches to bridge the potential relevance gaps between research and practice. A Delphi study of QM practitioners in Swedish private and public organisations, several of which operate globally, generated 49 challenges. An exploratory factor analysis was performed to cluster these challenges into themes, and the literature was reviewed to investigate how each theme has been addressed in QM research. The empirical investigation identified three themes related to future QM challenges—organisations’ adaptability to rapid changes in the business environment, quality as a strategic concern for business owners, and managerial ownership of quality. By analysing these challenges, six propositions for future research were proposed to reduce potential relevance gaps. Future research should focus on how to make QM a strategic concern for owners, and explore how it can contribute to organisational ambidexterity and adaptability. Research should also determine how context influences the way QM is applied, and investigate how it can improve organisational learning and innovation. Finally, research should indicate how top managers can adopt the responsibilities of quality managers, and explore the ways the principal values of QM can be better integrated into organisations.

Effects of procurement on project performance : a survey of Swedish construction clients
- 2009
-
In: Proceedings of CIB Joint International Symposium, Construction Facing Worldwide Challenges. - : ArCiBel Editores. - 9789536272358 ; , s. 19-28
-
Conference paper (peer-reviewed)abstract
- In order to increase the efficiency of the construction industry development and improvement of procurement procedures is vital. The purpose of this investigation is to increase the understanding of how procurement procedures affect project performance. A procurement model including eight hypotheses is first developed on the basis of a literature review and then tested through multivariate statistical techniques based on empirical data collected through a survey investigation of 106 Swedish construction clients. The results of hierarchical regression analyses show that cooperative procurement procedures positively affect collaboration among project actors and that collaboration in turn have positive effects on project performance. In general, however, cooperative procurement procedures do not have direct effects on project performance.
