Road safety plays an increasing role in communities throughout the entire world. According to estimates, road accidents will have moved from ninth to third in the worldwide ranking of burden of disease by 2020. This theme issue is dedicated to community-based applications that have the aim to enhance road safety. Although various interventions will be demonstrated, this issue provides by no means an exhaustive overview of community-based applications. The applications presented in this issue are predominantly meant to stimulate ideas and discussion on what can be done to enhance road safety.  相似文献

A total of 300 motorists were recruited at public places to answer a self-report questionnaire on a new community-based intervention to enhance road safety. The intervention consisted of a speed-displaying device that was mounted next to the road and was visible to both motorists and the public. The device gives feedback about the current speed of the motorist. The majority of motorists believed these devices influenced compliance with the speed limit. They indicated they approached locations with these devices more slowly than similar locations without such devices. Moreover, they slowed down if they were going faster than the speed limit. They also said that their reaction to the devices was not influenced by whether they were driving in a community where they had friends or in a community where nobody knew them. These results were consistent across gender, age, levels of education, and professions.  相似文献

During the 1960s in Egypt, a group of intellectuals and publicists with left-leaning tendencies sought to base their socialist views on Islamic principles by reading early Islamic history as a repository of heroes and villains to fit their model of Arab socialist society. Beyond political aggrandizement of Nasserism, this article claims that these intellectuals described Islam as socialist, which led them in unexpected directions. First and foremost, such study led several to make surprising claims regarding the leaders of early Islam that ipso facto brought them closer to the Shi?i view of this formative period of Islam. Rather than merely translating socialism into Islamic terminology, these scholars imbued early Islamic history with fresh and revolutionary meaning. The process of making Islam more relevant to twentieth-century Muslims meant re-examining age-old rivalries, which had the potential to change the relations between Sunni and Shi?i Islam dramatically.  相似文献

ABSTRACT

What is the role of collaborative management (CM) in enhancing environmental outputs? Does CM enable local municipalities to be better environmental performers? The present article addresses these two questions by means of a study of all urban localities in Israel (80% response rate). The aims of the study are to contribute to current research in two main ways. First, by addressing the question: Does CM enable local municipalities to be better environmental performers? In doing so, the study expands the very small number of studies conducted to date that examine performance and policy outputs of collaboration versus collaboration processes and procedures. Second, the study contributes to enlarging the very small number of relatively large N studies on collaborative public management that examine policy outputs. The main finding of this study highlights the important and positive role of CM in regard to local authorities’ environmental outputs.  相似文献

Fatty acid ethyl esters (FAEE) are products of the nonoxidative ethanol metabolism, which are known to be detectable in blood only about 24h after the last alcohol intake. After deposition in hair they should be suitable long-term markers of chronically elevated alcohol consumption. Therefore, a method for the analysis of ethyl myristate, ethyl palmitate, ethyl oleate and ethyl stearate from hair was developed based on the extraction of the hair sample by a dimethylsulphoxide (DMSO)/n-hexane mixture, separation and evaporation of the n-hexane phase and application of headspace solid-phase microextraction (HS-SPME) in combination with gas chromatography-mass spectrometry (GC-MS) to the extract. For use as internal standards, the corresponding D(5)-ethyl esters were prepared. The HS-SPME/GC-MS measurements were automatically performed using a multi-purpose sampler. The detection limits of the FAEE were between 0.01 and 0.04ng/mg and the reproducibility was between 3.5 and 16%. By application of the method to hair samples of 21 fatalities with known heavy alcohol abuse 0.045-2.4ng/mg ethyl myristate, 0.35-13.5ng/mg ethyl palmitate, 0.25-7.7ng/mg ethyl oleate and 0.05-3.85ng/mg ethyl stearate were measured. For social drinkers (30-60g ethanol per week), the concentrations were about one order of magnitude smaller. For 10 teetotalers negative results or traces of ethyl palmitate were found. It was shown by supplementary investigations in single cases that FAEE are also present in sebum, that there is no strong difference in their concentrations between pubic, chest and scalp hair, and that they are detectable in hair segments after a 2 months period of abstinence. From the results follows that the measurement of FAEE concentrations in hair is a useful way for a retrospective detection of alcohol abuse.  相似文献

The system for the adoption of children is not working well. The dysfunction of the adoption system manifests itself in an excess demand for healthy white babies and excess supply of older children, minority children, or those with disabilities. A market solution can increase the number of adoptions for older children, minority children or children with disabilities. Recognizing the heterogeneity of children and taking account of those differences will yield price differentiation in segmented markets. Such differentiation is especially important in the market for adopted children where the lifetime consequences of a poor match can be severe; more information about child attributes can only improve child-adopter matches. Revenues from the sale of adoption rights for highly demanded children could subsidize the adoption of the less desired children. The time to adoption will decrease and more of the less desired children will be adopted; the sum of consumer (adoptive parents) plus producer (biological mothers or the adoption agencies) surplus will rise and eliminate sub rosa markets for the more desired children.  相似文献
