Konferensbidrag (refereegranskat)abstract
- The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curved surfaces and formation of dust have been studied. Typical are stick slip behavior and threshold stress levels for formation of dust. The emission of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, micro structure, morphology and sizing of the fibres, the friction materials, the deformation rates and applied loads.

- 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.

- 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.

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.

Situational leadership in air traffic control
- 2007

Ingår i: Journal of Air Transportation. - 1544-6980. ; 12:1, s. 67-86
-
Tidskriftsartikel (refereegranskat)abstract
- In high-risk environments such as air traffic control, leadership on different levels plays a certain role in establishing, promoting, and maintaining a good safety culture. The current study aimed to investigate how leadership styles, leadership style adaptability, and over and under task leadership behavior differed across situations, operative conditions, leadership structures, and working tasks in an air traffic control setting. Study locations were two air traffic control centers in Sweden with different operational conditions and leadership structures, and an administrative air traffic management unit. Leadership was measured with a questionnaire based on Leader Effectiveness and Adaptability Description (LEAD; Blanchard, Zigarmi & Zigarmi, 2003; Hersey & Blanchard, 1988). The results showed that the situation had strong impact on the leadership in which the leadership behavior was more relationship oriented in Success and Group situations than in Hardship and Individual situations. The leadership adaptability was further superior in Success and Individual situations compared with Hardship and Group situations. Operational conditions, leadership structures and working tasks were, on the other hand, not associated with leadership behavior.

Ingår i: Ergonomics in the digital age. ; 5:Safety I, s. 368-371
-
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.

Computer-Aided Planning of Production, Working and Residential Environments
- 1996
-
Ingår i: International Journal of Industrial Ergonomics. - : Elsevier BV. - 0169-8141 .- 1872-8219. ; 17:1, s. 59-68
-
Tidskriftsartikel (refereegranskat)abstract
- This paper discusses a computer-aided planning methodology and its applicability for planning of industrial production and working environments as well as for planning of residential and working environments for the differently abled. The methodology has been developed and evaluated in six case studies in mechanical industries and in six case studies related to adaptations for the differently abled. The results from the case studies indicate that computer-supported modelling and visualisation may serve as a common and efficient language facilitating communication about multifaceted environmental planning issues. The methodology is a cost-effective way of demonstrating layout ideas and testing dynamic activities like manufacturing and transportation. Corporate groups comprising people involved in, or affected by, development work seem to be a fruitful approach for cooperation, one which enhances learning and creativity. Such groups may be a proper forum for the dissemination of information, exchange of opinions, utilisation of both expert and lay experiences, and for public testing of current reality or future plans in such a way that mutual understanding between different professional categories is increased, hence promoting internal commitment.
