  • Molecular characterization of Borrelia burgdorferi isolated from Ixodes ricinus in northern Sweden.
  • 1992
  • Ingår i: Scand J Infect Dis. - 0036-5548. ; 24:2, s. 181-8
  • Tidskriftsartikel (refereegranskat)abstract
    • Ixodes ricinus ticks, harbouring Borrelia burgdorferi, were found in an area in northern Sweden, not thought to be endemic for Lyme borreliosis. This investigation took place at Norrbyskär, an island situated in the Bothnian Gulf, 63 degrees 33'N/19 degrees 52'E. One of 42 nymphal and 8/43 adult I. ricinus ticks collected carried spirochetes as seen by phase contrast microscopy. Pure bacterial cultures were obtained from 2 of the ticks. Western blot analysis using species-specific monoclonal antibodies showed that the isolated spirochetes were B. burgdorferi. The identity of the isolated spirochetes was confirmed by DNA amplification using B. burgdorferi OspA and flagellin gene specific oligonucleotides as well as partial DNA sequencing of the respective OspA and flagellin genes. The 2 isolated spirochaete populations were different as shown by their protein profiles in sodium dodecyl sulphate polyacrylamide gels. Moreover, the demonstration of Lyme borreliosis in a patient from the island of Norrbyskär indicates the need for clinical consideration of this disease in northern Sweden.

  • Budget effectiveness in multinational companies : An empirical examination of environmental interaction on cognitive and affective effects of two dimensions of budgetary participation
  • 1993
  • Ingår i: Scandinavian Journal of Management. - Elsevier. - 0956-5221. ; 9:4, s. 299-316
  • Tidskriftsartikel (refereegranskat)abstract
    • This study examines the interaction between two dimensions of budgetary participation and environmental dynamism on perceptions of budget effectiveness in multinational companies. Unique features are dichotomies of: (i) domestic and foreign subunits; (ii) two dimensions of budget participation, communication and influence; and (iii) two facets of effectiveness perceptions, higher level involvement and outcomes of budget process. Results show that benefits of budgetary participation are limited and not consistent. Significant differences between foreign and domestic subunits are apparent. The primary perceived benefits are associated with communication. Budget influence is associated with positive perceptions of top-level involvement in foreign subunits but negative perceptions of outcomes of budget process in both domestic and foreign subunits.

  • Samarbete mellan hem och skola
  • 1993
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • The main purpose of this study was to shed light upon several questions regarding co -operation between the home and school, based upon earlier research and empirical studies. The study focused on the opportunities and drawbacks as well as on the motives for home and school cooperation. The first section deals with the questions at issues, and the bases the dissertation was dealt with. The second part covers the empirical studies which were carried out within the first three years of the primary school, and in the third part the limitations, most important results, and future research were discussed. The aim of the first section was to identify the starting points for the study, based on earlier research, and to review, via the main body of the study, how co-operation between the home and the school developed. An analysis of the review suggested that the goal formulations of the main body of the paper allowed for opportunities for home and school collaboration. Not only had interesting possibilities come to light, throughout the earlier research, but so too, a number of problems concerning the concrete collaboration between home and school. An very important conclusion, as a result of this review focused on the importance of proceeding from the unit that a class of pupils, parents and teachers represents. The purpose of the empirical studies was to describe and to try to understand why co-operation between home and school developed as it did. A longitudinal study was carried out by means of on-site research in the primary school itself, among pupils in years 1-3. This was proceeded by questionnaires and prestudies of selected classes. The data was collected mainly by means of questionnaires, interviews and written documents. The results showed that parents could function as a valuable resource within the work of the school and that it was relatively easy to take advantage of them, as such. It became clear that pupils, parents and teachers were extremely inventive and resourceful with regard to ideas on cooperation, and indeed on carrying through those ideas. Parents saw themselves and other parents as an important resource for the work of the school. The teacher emerged as a key figure for intensified collaboration. In the concluding discussion the results from the microlevel formed the starting point for the discussion concerning the context of cooperation between home and school at the macrolevel. As a conclusion, the discussion was about collaboration between home and school in terms of some of the effects of cooperation opportunities and obstacles, the interest shown by parents together with the content and forms of collaboration. Here it was pointed out that an important condition for achieving society's objectives was that pupils, parents and teachers together should interpret this in order to connect them to the cultural economic and social reality that was relevant to that particular class.

  • Vertical transport of lipid in seawater
  • 1993
  • Ingår i: Marine Ecology Progress Series. - 0171-8630. ; 98:1-2, s. 149-155
  • Tidskriftsartikel (refereegranskat)abstract
    • Lipids in seawater act as solvents and transporters of lipophilic organic pollutants. To investigate a possible transport route of lipophilic pollutants, the vertical flux of lipid was quantified during an annual cycle in the northern Baltic Sea. The lipid content in both sedimenting material and different size fractions of seawater was analyzed. During the year, 8 g lipid m-2 sedimented out from the photic zone to the benthic system. The sedimentation of lipid accounted for 300 to 400 % of the average standing stock of pelagic lipid and was concentrated in the spring bloom period (April-June) when 70 % of the total lipid sedimentation occurred. About 30 % of the produced pelagic lipid settled out from the system. In seawater the lipid maximum occurred at the end of the spring bloom, shortly after nutrient depletion, indicating a stress response in the algae. Since lipid sedimentation is concentrated in the spring bloom, removal of lipophilic organic pollutants may be important during this period.

  • Cross-cultural influences on temperament: : A comparison of Italian. Italo-Australian and Anglo-australian toddlers.
  • 1992
  • Ingår i: Australian psychologist. - 0005-0067. ; 27, s. 52-56
  • Tidskriftsartikel (refereegranskat)abstract
    • The temperament of three groups of 1- to 3-year-old children from Italy and Australia was compared using Australian and Italian versions of the Toddler Temperament Scale (Fullard, McDevitt,&Carey,1984). Italians, Australians, and Italo-Australians (Italian parent but living in Australia) differed on Intensity, Threshold, Approach, and Persistence dimensions of temperament, in ways which supported the stereotype of the sociable and “emotional” Italian temperament type. Overall, the Australians and the Italians were most different, with the Italo-Australians in between. Developmental differences in all groups were also observed. Mothers’ overall ratings of the child’s temperament was predicted by similar variables in the two Australian groups, but not in the Italian group. The findings support an interactional view of child temperament in its effects on development.

  • Stretchability of the rectus femoris muscle: : investigation of validity and intratester reliability of two methods including x-ray analysis of pelvic tilt.
  • 1993
  • Ingår i: Archives of Physical Medicine and Rehabilitation. - 0003-9993. ; 74:3, s. 263-270
  • Tidskriftsartikel (refereegranskat)abstract
    • Validity and intratester reliability of two test methods designed to identify stretchability of the rectus femoris muscle (RFM) was investigated, combined with x-ray analysis of pelvic tilt in the sagittal plane. The first method is commonly used in clinical practice. The second is a new technique supposed to tilt the pelvis posteriorly and thus further separate the origin and insertion of the muscle. Investigation of validity and intratester reliability of the two methods was made by testing and retesting a random sample of 71 persons. The tests were performed with an equipment that automatically recorded the angle of knee flexion from a previously determined applied torque, indicating the end point of motion for that particular subject. Angle of knee flexion and subjective estimation of pain sensation due to stretch were recorded at each measurement. The pelvic tilt-analysis consisted of test-retest reliability of x-ray measurements, comparison between the methods in both starting and final position, and x-ray and electronic goniometer measurements. All applied torques were measured with a strain gauge. Two out of three criteria of validity favored the new method and the third pointed out the two methods as equal. The two methods as well as the x-ray measurements showed high reliability, and the hypothesis of a more posterior tilted pelvis in the new method was confirmed. The electronic goniometer was less sensitive than x-ray, but proposed to analyse pelvic tilt clinically. Methodology procedures for joint angle measurements are discussed.
