Workplace intervention for improved risk perception and preventive activity among workers : using hand-held vibrating machines: a pilot study
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This article presents a pilot study of a 1-h workplace educational intervention implemented among ten construction workers who were highly exposed to hand–arm vibration. The intervention combined risk communication and normative expert advice intended to reinforce preventive behaviour related to vibration, noise, and biomechanical loads. Data for this study comprised intervention notes and interview data from interventionists, and pre- and post-intervention interview data from participating workers.The results suggested that the intervention was sensitive to disturbances and should be directed only to motivated workers possessing sufficient self-efficacy, and only in circumstances in which exposure may be controlled on the local workplace level and by locally implemented measures. Unless these conditions are present, the studied intervention may fail to influence preventive behaviour, and may instead cause cognitive dissonance and frustration among participants and interventionists.

Arkeologi och mångkultur : rapport från Svenskt arkeologmöte 2006
- 2006
-
Proceedings (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Vilka utmaningar står arkeologin inför i det mångkulturella samhället? Håller vår syn på det förflutna på att förändras? Eller är det snarare så att det förflutna kan få oss att se på dagens samhälle med nya ögon? Och vad händer om vi blickar framåt? Måste vi ha gemensamma minnen för att känna samhörighet med varandra? Dessa och andra frågor diskuteras här av arkeologer, etnologer, historiker och kulturdebattörer.

De små båtarna och den stora flykten : Arkeologi i spåren av andra världskrigets baltiska flyktbåtar

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Baltic states, Estonia, Latvia and Lithuania, were occupied no less than three times during the Second World War. Faced with a reign of terror, the threat of deportation, and compulsory conscription, over 30,000 people fled over the Baltic Sea to Sweden. On their arrival in Sweden, most escape boats were confiscated by the authorities and in 1945 were returned to the Soviet Union.This study, which began as an attempt to find out about the Baltic escape boats that ended up in Sweden, is inspired by a foreign boat in a small fishing harbour on the island of Gotland. My curiosity was piqued when I caught sight of the boat and heard that it had probably been an escape boat.The purpose of this thesis is to establish which, if any, Baltic escape boats survive in Sweden, in which contexts they remain, and to review their state of preservation, as well as to answer the question of their significance for the memory of the escape. It is an archaeology of the escape and its aftermath, based on the surviving escape boats – what the boats say about the escape, what happened to them afterwards, and how people relate to them and their historical legacy today.The study looks at 35 boats that have been described as Baltic escape boats in various contexts. It shows that they are found in a multitude of environments and in a range of different states of preservation. The boats illustrate experiences that few other source materials can convey, in a manner pertinent to the archaeological understanding of flight. In addition, the boats are rare traces of an earlier Estonian coastal culture eradicated by the second Soviet occupation.One of the most important outcomes of the study is the documentation from the survey and examinations carried out. Few of the boats were known outside their local context. A national compilation has been lacking, which has impeded research and ultimately our understanding of the breadth and complexity of the Swedish historical landscape when it comes to ship remains.

A follow-up study of welders’ exposure to vibration in a heavy engineering production workshop

- Manual work involving vibrating power tools is associated with symptoms that include vascular, neurological and musculoskeletal disorders. This study examines the vibration exposure of welders to determine the change between 1987 and 2008. Vibration measurements on handheld tools were used to evaluate the acceleration and the daily exposure time was determined by subjective rating. From these data, the 8-hour equivalent vibration exposure A(8), has been calculated. During the period, the A(8) decreased from 3.9 m/s2 to 1.9 m/s2. It was concluded that this decrease is the result of fewer vibrating tools and a decrease in daily exposure time. Although the daily vibration exposure has decreased over the study time, for some welders the daily vibration exposure A(8) is still above the action value set by the EU directive on vibration. This means more effort should be spent to decrease vibration exposure.

Konferensbidrag (refereegranskat)abstract
- Objective This study focuses on the acute effects of vibration and how vibrations influence the measures of the thermal perception thresholds during different vibration magnitudes, frequencies, and durations.Methods The fingers of ten healthy subjects, five males and five females, were exposed to vibration under 16 conditions with a combination of different frequency, intensity and exposure time. The vibration frequency was 31.5 and 125 Hz and exposure lasted between 2 and 16 min. The energy-equivalent frequency weighted acceleration, according to ISO 5349-1, for the experimental time of 16 min was 2.5 or 5.0 m/s(2) (r.m.s.), corresponding to a 8-h equivalent acceleration, A(8) of 0.46 and 0.92 m/s(2), respectively. A measure of the thermal perception of cold and warmth was conducted before the different exposures to vibration. Immediately after the vibration exposure the acute effect was measured continuously on the exposed index finger for the first 75 s, followed by 30 s of measures at every minute for a maximum of 10 min. If the subject's thermal thresholds had not recovered, the measures continued for a maximum of 30 min with measurements taken every 5 min.Results For all experimental conditions and 30 s after exposure, the mean changes of the thresholds compared with the pre-test were found to be 0.05 and -0.67C for the warmth and cold thresholds, respectively. The effect of the vibration exposure was only significant on the cold threshold and only for the first minute after exposure when the threshold was decreased. The warmth threshold was not significantly affected at all. The frequency and the exposure time of the vibration stimuli had no significant influence on the perception thresholds for the sensation of cold or warmth. Increased equivalent frequency weighted acceleration resulted in a significant decrease of the subjects' cold threshold, not the warmth. The thresholds were unaffected when changes in the vibration magnitude were expressed as the frequency weighted acceleration or the unweighted acceleration.Conclusion When testing for the thermotactile thresholds, exposure to vibration on the day of a test might influence the results. Until further knowledge is obtained the previous praxis of 2 h avoidance of vibration exposure before assessment is recommended.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Overcrowding in the emergency department (ED) may negatively affect patient outcomes, so different triage models have been introduced to improve performance. Physician-led team triage obtains better results than other triage models. We compared efficiency and quality measures before and after reorganization of the triage model in the ED at our county hospital.MATERIALS AND METHODS: We retrospectively compared two study periods with different triage models: nurse triage in 2008 (baseline) and physician-led team triage in 2012 (follow-up). Physician-led team triage was in use during day-time and early evenings on weekdays. Data were collected from electronic medical charts and the National Mortality Register.RESULTS: We included 20,073 attendances in 2008 and 23,765 in 2012. The time from registration to physician presentation decreased from 80 to 33 min (P < 0.001), and the length of stay decreased from 219 to 185 min (P < 0.001) from 2008 to 2012, respectively. All of the quality variables differed significantly between the two periods, with better results in 2012. The odds ratio for patients who left before being seen or before treatment was completed was 0.62 (95% confidence interval 0.54-0.72). The corresponding result for unscheduled returns was 0.36 (0.32-0.40), and for the mortality rates within 7 and 30 days 0.72 (0.59-0.88) and 0.84 (0.73-0.97), respectively. The admission rate was 37% at baseline and 32% at follow-up (P < 0.001).CONCLUSION: Physician-led team triage improved the efficiency and quality in EDs.
