- PURPOSE: The present aim was to evaluate the effect of systematic multi-professional co-ordinated rehabilitation (the Stockholm Co-operation Project) on the number of days' sick leave during the first and second half-years after the rehabilitation co-ordination period, compared to the year before. Another aim was to evaluate the economic effects at national level. METHOD: A matched-pairs design was used. The study group was based on 64 rehabilitees employed by a public employer in Stockholm, who took part in a systematic multi-professional co-operation project. To obtain pairs, the 64 individuals were individually matched with 64 people who received conventionally organised rehabilitation. Thus, there were 128 subjects altogether. RESULTS: The study group had substantially less sick leave days per month than the comparison group during the second half-year after the rehabilitation co-ordination period. The effect was even greater in a subgroup with more previous sick leave. During the first half-year after the intervention the comparison group had relatively more sick leave. No effect was found for a subgroup with less previous sick leave. The economic benefit of the intervention was estimated to 1,278 euros per month and person based on the whole group, and to 2,405 euros per month and person based on those with more sick leave. CONCLUSIONS: People who undergo co-ordinated rehabilitation have more working days after the intervention period than those with conventional rehabilitation. This way for rehabilitation actors to co-operate gives better outcomes for rehabilitation cases with long previous sick leave, but not for cases with less previous sick leave. It also generates economic gains at several levels.

Konferensbidrag (refereegranskat)abstract
- In several European countries, the design of stress laminated bridges has been conducted according to a simplified method developed by M. A. Ritter in the 1990’s, valid for American wood species such as Douglas fir. According to this method a stress laminated deck can be designed as a beam with cross section dimensions beff x t, where beff is a fictitious (or effective) width - determined according to orthotropic plate theory - and t is the thickness of the deck. However, there are several uncertainties concerning the validity of this model concerning its application to European stress laminated bridges. These uncertainties are related to: (1) wood species - in Europe boards or glulam of Norway spruce or Scots pine are generally used; (2) design philosophy - Ritter’s model was developed according to the “allowable stresses design method”, whilst the philosophy behind the Eurocodes is the design method according to the ultimate limit states.In this paper, an experimental investigation on specimens manufactured with pre-stressed glulam will be presented. The glulam is made from Norway spruce. The aim of the study is to estimate the mechanical properties of stress laminated timber decks with varying pre-stressingforces. The methods for measuring (a) transversal modulus of elasticity ET , and (b) the transverse shear modulus GLT will be presented. Comparison with results obtained by this research and results obtained by other researcher will be shown.

Skolinspektioner - i tid och otid
- 2007
-
Rapport (refereegranskat)abstract
- Skolinspektionens historia ges en rapsodisk översikt. De 187 grundskolor som inspekterades av Skolverket 2003 och 2004 i Sverige granskas med avseende på förändringar före respektive efter inspektioners genomförande i elevernas skolprestationer. Inspektionerna visar sig inte inverka på elevernas skolresultat. Vid 71% av de inspekterade skolorna försämrades skolresultaten eller blev kvar på tidigare nivå
