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.

- Background: In recent years an increase of the incidence of nosocomial outbreaks caused by noroviruses has been observed throughout Sweden, with high peaks noted in the winter seasons 2002/2003 and 2004/2005, respectively. Objectives: To phylogenetically characterize norovirus strains causing nosocomial outbreaks from 1997 to 2005 and estimate the impact of norovirus-like disease on the Swedish health care system during the peak season 2002/2003 when a new variant of norovirus occurred. Study design: Stool samples from 115 randomly selected nosocomial outbreaks occurring during 1997-2005 throughout Sweden were studied by RT-PCR and sequencing. In addition, to investigate the impact on the health-care system, a questionnaire was distributed to infection control units (n = 90) serving all Swedish hospitals, nursing homes and other health-care institutions during the largest epidemic of nosocomial outbreaks. Results: Sequencing of 279 nucleotides of the norovirus RNA polymerase gene in stools containing norovirus RNA showed that strains belonging to the GII.4 genotype dominated. Each of the two large epidemics was due to a new variant within this cluster. The questionnaire revealed that 30,000-35,000 episodes of nosocomial norovirus-like infections occurred in 80 of 82 major Swedish hospitals affected in 2002/2003. Conclusion: New norovirus variants within the cluster GGII.4 may have a major impact on the health-care system. (c) 2008 Elsevier B.V. All rights reserved.

- Objectives: While suicidal behaviour has become less prevalent in non-manual workers in recent decades, rates have increased in manual workers. We aimed to identify occupations within the construction industry with excess risk of suicide and non-fatal self-harm.Methods: This cohort of Swedish construction workers comprises 389 132 individuals examined 1971-1993 and followed 1987-2018 using national hospital and cause of death registers. More than 200 job titles were merged into 22 occupational groups. For 296 891 men alive in 1987 and active in the construction sector, survival was calculated from baseline to first event of non-fatal self-harm or suicide and censored for emigration, long-term unemployment, disability pension, retirement, death from other causes or end of follow-up. HRs with 95% CIs were obtained from multiple Cox proportional hazard regression.Results: Overall, 1618 cases of suicide and 4774 events of non-fatal self-harm were registered. Self-harm before baseline was the single largest risk factor for suicide, HR 9.3 (95% CI 7.5 to 11.6). Compared with the overall mean, labourers and rock workers had excess risk for suicide, HR 1.4 (95% CI 1.1 to 1.7) and 1.5 (95% CI 1.0 to 2.3), respectively, while electricians, clerks and foremen had reduced risk. Labourers, concrete workers, sheet metal workers, painters, glaziers and the group € other construction workers' were at increased risk for non-fatal self-harm. Almost all categories of manual workers were at increased risk for suicidal behaviour relative to clerks and foremen.Conclusions: Specific occupations within the construction sector were associated with excess risk for suicidal behaviour. Future studies should identify underlying risk factors to inform tailored interventions.

Pathogen-induced defoliation of Pinus sylvestris leads to tree decline and death from secondary biotic factors

Tidskriftsartikel (refereegranskat)abstract
- The contribution of non-lethal pathogenic attacks to tree death is still unclear. Manion's theory of the spiral of decline predicts that tree decline and death occurs because of a sequence of predisposing, inciting and contributing events. To understand whether pathogens can act as predisposing or inciting factors, we tested whether a sequence of non-lethal pathogen attacks causing crown defoliation could lead to a chronic decline in tree health and predispose trees to die. Scots pine (Pinus sylvestris) trees predisposed or escaping (non-predisposed) a first outbreak by the pathogen Gremmeniella abietina (predisposing event) were compared in terms of survival and susceptibility to secondary pests (contributing event) after a second G. abietina outbreak (inciting event). Four years after the inciting event, mortality among predisposed trees was up to five times higher than among trees escaping the first epidemic. Predisposed trees were twice as susceptible to secondary attacks by the common pine shoot beetle (Tomicus piniperda). Ten years after the inciting event, severely predisposed trees had not been able to restore their crowns and still showed stagnated growth. This study showed that pathogen-induced defoliation can act as predisposing and inciting factors for tree death, reducing the capacity of trees to survive short- or long-term stressing events, such as bark beetle attacks. We also showed that tree decline can result from a combination of predisposing and inciting events caused by pathogens. (C) 2016 Elsevier B.V. All rights reserved.

Om det förändrade ansvaret för skolan : vägen till mål- och resultatstyrning och några av dess konsekvenser

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- (On the shift of responsibility for compulsory schooling. The path to management by objectives and results and some of its consequences). The aim with this thesis is to contribute to the discussion about the responsibility for compulsory schooling in the 1990s. The decade began with a shift of responsibility for the compulsory school, a process generally referred to as 'municipalization', which on an everyday basis makes it perfectly clear where the responsibility lies. This thesis probes a little further into the problems of the distribution of responsibility, through investigating how the issue of responsibility for the nine-year comprehensive compulsory school has been discussed and motivated over time, in order to analyse more precisely the conditions at hand as the municipalities were to take over responsibility for the different schools in the 1990s. As a sequel to the fundamental direction of this study it enters into a discussion about the consequences following the distribution of responsibility: the effects of management by objectives and results on the school's cognitive approach and problematizing the issue of power and influence under the new model of responsibility. The thesis contains an analysis of how the issue of responsibility for compulsory schooling has been discussed in official commission reports over time, with the purpose of gaining a better understanding of the compulsory school in the 1990s, and its conditions. The historical study thus focuses on the school reform conducted in the early 90s and the three concepts seen as central to the discussion about responsibility for the compulsory school towards the end of the twentieth century: municipalization, decentralization and turning the school into a goals and achievement-related organisation. The analysis is founded upon an outlook based on discourse, aiming to distinguish any changes in the meaning of those three key expressions as well as to define shifts and discursive breaks in textual references to the responsibility for comprehensive school.
