This paper updates results of an international study aimed at quantifying the links between transport disadvantage (TD), social exclusion (SE) and well-being (WB) in Melbourne, Australia. The study extends knowledge associated with SE and transport by quantify social and behavioural implications of lack of public and private transport and the nature of the social WB benefits associated with improving services.Study aims and methodology are outlined. Recent findings covered relate to car ownership on the urban fringe, patterns of transport disadvantage, the analysis of time poverty related to transport disadvantage, measuring the economic value of additional mobility and use of a Structural Equation Model (SEM) to relate WB and SE to TD and a series of explanatory factors.Overall results suggest that those without a car on the urban fringe adjust well with their circumstances by living close to activity centres. They demonstrate sustainable choices, trading off budgets and home location to balance mobility and accessibility. Poorer households with high car ownership value mobility and cheaper more remote fringe dwellings but demonstrate numerous strategies to reduce high car costs which are acknowledged as a significant burden. Analysis identifies 4 key types of transport disadvantage including a ‘vulnerable/impaired’ group which should be of much greater concern for targeted policy than others due to poor scoring on SE and WB scales. The economic value of new mobility is also explored with results suggesting $AUD 20 per average new trip which is four times larger than conventional values for generated travel.Analysis has also suggested that transport disadvantage can relate to socially advantaged as well as socially disadvantaged groups through time poverty. This was found to be an important mitigating factor when relating TD to WB. A statistically reliable structural equation model is developed suggesting the SE-WB link is strong (−.87) with a modest link between TD-SE (.27).Areas for future research in the project are also summarised. 相似文献

In this paper we report the conclusion of a research project dedicated to pricing regimes in public-private partnership contracts for the provision of transport infrastructure (Macário et al., 2009). Several elements have been brought to the bulk of knowledge that supports the design and implementation of public-private partnership in the transport sector. These developments have been achieved in the following domain:
- •
- Understand difficulties of price setting within the PPP environment, given the potential conflict of interest among the different parties engaged, go beyond the discussion of first best versus second-best price setting mechanisms.
- •
- Understand the role of government and regulators in the performance of a PPP.
- •
- Translate the issue of asymmetries of information between parties into a risk taking language.
- •
- Devise alternative contractual designs that will enable competitive price setting.
- •
- Understand that a structural element is missing to conciliate the views of the different stakeholders over a PPP: a bridge between infrastructure costs and charges.

近来,秘鲁鱼粉在远洋运输过程中屡次发生自然事故。本文就这一现象从鱼粉的组成、性质、抗氧剂的处理程度以及运输积裁条件加以分析,阐述了鱼粉发生自燃的诸多原因。并根据实际案例、秘鲁当地对鱼粉抗氧剂处理过程的现状及商检部门的检测方法等方面的资料分析,指出了秘鲁鱼粉在运输过程中发生自燃的主要原因是鱼粉中的抗氧剂分布不均匀,致使那些抗氧剂浓度不足的鱼粉在运输途中抗氧剂含量逐渐消耗而发生氧化反应,产生大量的氧化热,达到鱼粉的自燃点而发生自燃。 相似文献
