- In order to extend our previous findings of genetic linkage to the CD28/CTLA4/ICOS region on chromosome 2q33 (CELIAC3) in coeliac disease (CD), we have investigated 22 genetic markers in 325 Norwegian/Swedish multiplex and simplex CD families. We found both linkage and association with several markers, primarily in the multiplex material. We observed strong linkage disequilibrium (LD) between SNPs (Single Nucleotide Polymorphisms) within an LD block delimited by MH30 and D2S72. A haplotype of this region marked by the alleles -1147*T: + 49*A:CT60*G:CT61*A was significantly associated with CD, suggesting that one or more polymorphisms of this haplotype, possibly -1147*T, are involved in CD susceptibility. The CT60 SNP, a polymorphism found to be most strongly associated with some other immune-mediated diseases, was not associated with CD, as this SNP was part of both associated and non-associated haplotypes. Moreover, our results suggest that CELIAC3 harbours several independent loci contributing to CD susceptibility.

Aspects of Organizational Psychology and Innovation in Air Traffic Control

- In order to adapt to new conditions that increasing air traffic volumes bring forward, the Swedish Air Navigation Services (ANS) is going through a process of change. In order to meet the new conditions it will be necessary to be more efficient in the work of handling the air traffic. New conditions bring forward new demands, not only on technology and methods used, but also on organizational structures and individual employees. The challenge is to make the adaptation in ways that do not affect the safety standards. The Swedish air traffic control, ATC centers in Malmö and Stockholm are adjusting their activity to meet the new situations in mainly two ways: a new team-based organization has recently been introduced and a new ATC system will soon be installed.

Organisational climate and psychosocial work environment in air traffic control
- 2004

Ingår i: Book of abstracts of the 6th European Conference of the European Academy of Occupational Health Psychology.
-
Konferensbidrag (refereegranskat)abstract
- Air traffic control in Sweden is being studied in a joint long-term project between Lund University and the Swedish Air Navigation Services (ANS).The project aims to investigate how different organisational aspects such as organisational climate, team climate, leadership, psychosocial work environment and safety culture will be affected by ongoing organisational and technical changes. The basic research design comprises three studies, two prior to the introduction of a new air traffic control system and one after. This design has provided opportunities to compare the situation before and after the system introduction. The first and the second studies have been completed and the results concerning organisational climate and psychosocial work environment are the focus of this paper.

Organizational climate in air traffic control
- 2002

Ingår i: European Academy of Occupational Health Psychology conference proceedings series. - 1473-0200. ; , s. 24-27

Konferensbidrag (refereegranskat)abstract
- A positive and innovative organizational climate is of great importance in order to manage and adapt to change. Such a climate seldom evolves in organizations closely governed by rules and regulations. Because of ongoing organizational and technical changes within the Swedish Air Navigation Services Provider, a study concerning the organizational climate for changes and innovations was conducted to investigate the organization’s capacity to cope with changes. Study locations were the two Swedish main air traffic control centers and parts of the civil aviation administration headquarters. 390 subjects took part in the study and the CCQ questionnaire was used to measure the organizational climate. The results show that the organizational climate is quite positive despite the rule governed work. The results also show that administrative personnel assess the organizational climate as more positive than operative personnel. Comparisons between management positions did not result in any differences.

Relationship between safety culture and psychosocial working environment in air traffic control
- 2004

Ingår i: Proceedings of the International Conference on Human-Computer Interaction in Aeronautics.

Konferensbidrag (refereegranskat)abstract
- The Swedish Air Navigation Service Provider in cooperation with the University of Lund aims at developing a model for supporting continuous improvements and learning focusing on safety in air traffic control. This paper focuses on relationships between the safety culture and the psychosocial working environment. These areas were studied using questionnaires at the two main air traffic control centres in Sweden and a part of the central civil aviation administration. The results showed that some associations exist between the two concepts and that this was true within all three study locations.

Team climate and safety culture in air traffic control

Konferensbidrag (refereegranskat)abstract
- In a joint project – Human Factors in ANS, HUFA - between the Swedish Civil Aviation Administration and Lund University the aim is to find out how a new team-based organization and the introduction of a new air traffic control system will affect safety culture and psychosocial working environment by changes in organizational climate, team climate and leadership. All in all, four studies will be conducted, before and after the system introduction, involving the two air traffic control centers (ATCC) in Malmö and Stockholm as well as the air navigation services (ANS) division in Norrköping. This paper focus on findings from the first study concerning the team climate and the safety culture. The results show an overall positive picture concerning the safety culture at all three units. The team climate is assessed as average at the two ATCCs and just above at the ANS-division. No clear patterns could be found that can explain if and how the safety culture and the team climate are related.

Team climate and situational leadership in air traffic control
- 2003

Ingår i: Proceedings of the Fifth European Conference of the European Academy of Occupational Health Psychology. ; , s. 14-18
-
Konferensbidrag (refereegranskat)abstract
- In a joint project between the Swedish Civil Aviation Administration (SCAA) and Lund University, questions concerning organizational aspects - such as organizational climate, team climate, situational leadership, psychosocial working environment - and safety culture are under study. A team-based organization has recently been introduced and a new air traffic control system will soon be installed at the two main air traffic control centers (ATCC) in Sweden. To find out how these changes will affect the organizational aspects and the safety culture, four studies will be conducted. These studies will involve the two air traffic control centers in Malmö and Stockholm as well as the Air Navigation Services Headquarters in Norrköping (ANS). The first study conducted about a year before the introduction of the new system, has been accomplished. The second study will be conducted just before the system introduction, the third directly after the introduction and the fourth approximately six months later. This design gives the opportunity to compare the situations before and after the system introduction.
