《法国商法典》2000年修订的差异化特征及其再发展述评

与1807年《法国商法典》相比,2000年《法国商法典》立足法国商事活动的发展变化而不断丰富实践,充分汲取两百余年的实践经验,已经形成一套体例完备、原则清晰、运作规范的法律体系,成为欧洲民商立法的典范。立法者在该法的概念界定、适应场域等方面几经思考沉淀,在立法原则方面,该部法典也是历经商主体主义到商行为主义再到折中主义的不断演进。但是由于时代更迭的现实需要,20年来,《法国商法典》的再发展与最新修订与时俱进、效果明显。本文尝试通过对比1807年和2000年《法国商法典》,评述2000年《法国商法典》的特点,并对2000年以来的再发展特征加以描述性解释,介绍其最新成果,以期为中国民商事立法提供有益的“法国经验”。     

Compulsory child restraint seat law and motor vehicle child occupant deaths and injuries in Japan 1994-2005

The purpose of child restraint seats (CRS) is to reduce the number of individuals killed or injured in motor vehicle (MV) crashes. Japanese Road Traffic Law 17-3-4 (April 2000) specifies a requirement that CRS be used for all children aged 0-5 years. The objective of this evaluation was to determine the legislative impact on fatalities in Japan for the period 1994-2005. Data were obtained from the Institute for Traffic Accident Research and Data Analysis. A time-series Poisson regression model was used to analyse the change (6 years pre/post) in incidence rate ratios of fatality and injury in MV crashes among children ages 0-5 years. Despite increases in CRS use, fatalities failed to decrease significantly after enactment of the law (incidence rate ratio: 0.80; 95% CI: 0.49-1.31). In 2005, 67% of children aged 0-5 years, who were killed as MV occupants were not seated in CRS. Between 2000 and 2005, the lack of CRS led to 43% of front seat passenger deaths, 54% of rear seat deaths, 143 children died in total and 500 + children were seriously injured. It was found that the compulsory CRS law enacted in April 2000 did not result in a statistically significant reduction in child MV occupant fatalities and injuries in Japan.

Pedestrian traffic injuries in Mexico: A country update

Road traffic injuries in general and pedestrian injuries in particular are a major public health problem in Mexico, especially in large urban areas. Analysis of mortality and road crashes at the national level was done using routine data recorded on death certificates. Fatality rates for different age groups were estimated by region for the year 2000. These data were supplemented by a cross-sectional study of pedestrian injuries in Mexico City based on death certificates information for pedestrians who lived and died in Mexico City between 1994 and 1997. Participant observation of physical spaces where crashes occurred was carried out. The spaces were filmed and in-depth interviews of survivors conducted. Road traffic crashes were responsible for approximately 17,500 deaths in Mexico during 2000. The mean age of the victims was 37 years. Mexico lost an average of 30 years of productive life for each individual who died in a traffic crash – 525,000 years in 2000. An estimated 9500 (54.3%) of all fatalities were pedestrians, and for every pedestrian death there were 13 others who sustained nonfatal injuries requiring medical care. The overall crude mortality rate for pedestrian injuries in Mexico City was 7.14 per 100,000 (CI 6.85-7.42). A concentration of deaths was observed in 10 neighborhoods at specific types of street environments. The underlying factors included dangerous crossings and the absence or inadequacy of pedestrian bridges, as well as negative perceptions of road safety by pedestrians. In conclusion, this study demonstrates the importance of elucidating the underlying contextual determinants of pedestrian injuries.

Analysis of fatal injuries in Serbian underground coal mines – 50 years review

Abstract

The study presented here analyzes mining accidents and fatal injuries in Serbian underground coal mines over a period of 50?years, in order to assess the effectiveness of legislation changes in the overall safety of work environment. Two distinct periods, prior to 2000 and after 2000 were compared. The data from the period after 2000 were further analyzed to provide better understanding of the results. In order to assess the overall state of safety in Serbian mines, the data on fatal injuries were also compared to the international data. It was found that the legislative changes are more easily accepted by the common workers than by the mine management. Consequently, the key recommendation for the safety of coal mine companies in Serbia is the investment in the new technology. Additionally, mine management should be in the focus of the mining inspection with a stronger penal policy regarding mine safety neglect.
