The factors of female taxi drivers’ speeding offenses in Taiwan

Abstract: Females choosing taxi driving as a career is rare, therefore, investigating such samples is often difficult. Speeding is one of the most common driving violations, however, there has been no research looking into female taxi drivers’ speeding issue. This study explores the factors of female taxi drivers’ speeding offenses in Taiwan. Data is based on a national survey and includes 235 professional female taxi drivers. The results indicate that female taxi drivers work approximately 27.37 days per month, at a mean of 9.76 h per day. Of the female taxi drivers represented in this study, 22.8% reported at least one speeding offense over a one-year period. The results of a logistic regression model reveal that the determinant factors associated with female taxi drivers’ speeding offenses are significantly related to age, educational level and mileage driven. However, job experience, business operating style, and vehicle engine size are not associated with committing speeding offenses. Practical implications for traffic safety of female taxi drivers are also discussed.

Development of a Water Quality and Bio‐Accumulation Model for the Scheldt Estuary

Abstract: Estuaries are one of the most important coastal features for mankind. Large civilizations have developed on the shores of many estuaries and most of the present day harbours and large industries are located within their sphere. This often results in water quality problems in many estuaries, including the Scheldt estuary. This estuary is faced with two major problems: 1. Extensive dredging and dumping operations of (contaminated) sediments, necessary to keep the port of Antwerp accessible and 2. Large domestic and industrial waste-water discharges. This results, for example, in low or even zero oxygen concentrations in the upper estuary and high concentrations of micro-pollutants in the biota and abiota. A few years ago Rijkswaterstaat, the authority responsible for the management of the Western Scheldt, decided to built a management oriented model related to the second problem: the influence of the large waste—water discharges on the ecosystem of the Western Scheldt. The objective of the project was to develop a coupled transport, chemical/biochemical and bio-accumulation model for pollutants/micro-pollutants for the Scheldt estuary Pollutants/micro-pollutants in this context does not only mean heavy metals and/or organics, but also BOD, COD and nutrients (N, P. Si). The model attempts to relate the pollutant discharges into the estuary to the concentrations found in organisms (Tidal Waters Division, 1987).

Integrated flood management: experiences of 13 countries with their implementation and day-to-day management

Abstract: Dans le cadre du 3eme colloque international sur la protection contre les inondations (ISFD3, Pays-Bas, 25-27 mai 2005), une session speciale a ete organisee pour les dirigeants d'organismes de gestion d'inondation dans 13 pays du monde. Le but etait d'echanger leurs experiences de la pratique de gestion integree des inondations et de la gestion au jour le jour. Bien que ces pays different considerablement en ce qui concerne les problemes d'inondation qu'ils rencontrent ainsi qu'en matiere de socio-economie et d'organisation, quelques traits communs ont emerge: defi consistant a traduire une approche basee sur le risque a l'echelle d'un bassin en mesures concretes, responsabilite et conscience du risque d'inondation, harmonisation de la gestion des risques d'inondation avec la planification d'occupation de l'espace, cooperation institutionnelle, et confrontation a des budgets de maintenance insuffisants. La session speciale s'est conclue sur des recommandations pour la gestion et la recherche. Cet article presente les principales discussions et conclusions de cette session.
