It is a challenge to reduce the ever-increasing flow of waste. In Norway the systems for recycling of organic waste, paper, glass, metals, etc. differ between municipalities, both with regard to organizational and to technological structures. Our hypothesis is that people's attitudes and behaviour may differ with different systems of waste management. People's behaviour and attitudes regarding (organic) waste recycling were investigated in two municipalities with differing technical and organisational systems. Data came from interviews with municipal employees, questionnaires, focus groups and multi-criteria mapping. People seem to be better informed and more positive about organic waste recycling in one of the municipalities (MH, which has recycling of organic waste) than in the other (MS, which has no such recycling). The two municipalities had similar sets of important criteria for waste management (price, environmental friendliness, easy solutions, information). Many participants stated that they had learned from the group process, though only a few reported changed preferences. The institutional context seems to be important for people's behaviour and attitudes towards waste management. This implies that people's recycling behaviour does not only depend on technical and organisational aspects, but also on institutions. These are important messages for policy makers. On an individual basis, the different systems in the two municipalities seem to affect people's stated attitudes. These differences diminish when they are in a common setting where process and dialogue stimulate new thoughts and encourage people to act more altruistically. 相似文献
Objective: The objective of this study was to determine the roadside prevalence of alcohol-impaired driving among drivers and riders in northern Ghana. The study also verifies motorists' perceptions of their own alcohol use and knowledge of the legal blood alcohol concentration (BAC) limit in Ghana.
Method: With the assistance of police, systematic random sampling was used to collect data at roadblocks using a cross-sectional study design. Breathalyzers were used to screen whether motorists had detectable alcohol in their breath and follow-up breath tests were conducted to measure the actual breath alcohol levels among positive participants.
Results: In all, 9.7% of the 789 participants had detectable alcohol, among whom 6% exceeded the legal BAC limit of 0.08%. The prevalence of alcohol-impaired driving/riding was highest among cyclists (10% of all cyclists breath-tested) followed by truck drivers (9%) and motorcyclists (7% of all motorcyclists breath-tested). The occurrence of a positive BAC among cyclists was about 8 times higher (odds ratio [OR] = 7.73; P < .001) and it was 2 times higher among motorcyclists (OR = 2.30; P = .039) compared to private car drivers. The likelihood for detecting a positive BAC among male motorists/riders was higher than that among females (OR = 1.67; P = .354). The odds for detecting a positive BAC among weekend motorists/riders was significantly higher than on weekdays (OR = 2.62; P = .001).
Conclusion: Alcohol-impaired driving/riding in Ghana is high by international standards. In order to attenuate the harmful effects of alcohol misuse such as alcohol-impaired driving/riding, there is the need to educate road users about how much alcohol they can consume and stay below the legal limit. The police should also initiate random breath testing to instill the deterrence of detection, certainty of apprehension and punishment, and severity and celerity of punishment among drink-driving motorists and riders. 相似文献
Aim. Firefighters must meet minimum physical demands. The Norwegian Labour Inspection Authority (NLIA) has approved a standardised treadmill walking test and 3 simple strength tests for smoke divers. The results of the Trondheim test were compared with those of the NLIA tests taking into account possible effects of age, experience level and gender. Methods. Four groups of participants took part in the tests: 19 young experienced firefighters, 24 senior male firefighters and inexperienced applicants, 12 male and 8 female. Results. Oxygen uptake (VO2) at exhaustion rose linearly by the duration of the treadmill test. Time spent on the Trondheim test was closely related to performance time and peak VO2 on the treadmill test. Senior experienced firefighters did not perform better than equally fit young applicants. However, female applicants performed poorer on the Trondheim test than on the treadmill test. Performance on the Trondheim test was not closely related to muscle strength beyond a minimum. Conclusion. Firefighters completing the Trondheim test in under 19 min fit the requirements of the NLIA treadmill test. The Trondheim test can be used as an alternative to the NLIA tests for testing aerobic fitness but not for muscular strength. Women’s result of the Trondheim test were poorer than the results of the NLIA treadmill test, probably because of their lower body mass. 相似文献
