Transport problems that matter - social and psychological links to transport disadvantage

This paper presents an analysis exploring self-reported measures of transport disadvantage and how these relate to social exclusion and well-being in Melbourne, Australia. A sample of 535 individuals sourced from a household survey explores ratings of 18 types of transport problems. The questionnaire also measured social exclusion represented in five dimensions including income, unemployment, political engagement, participation in activities and social support networks. Well-being was also measured adopting standard psychological measures of ‘Satisfaction with Life’, ‘Personal Well-being Index,’ ‘Positive Affect’ and ‘Negative Affect’.A factor analysis of self-reported transport difficulties identified four statistically significant sub-scales (‘transport disadvantage’, ‘transit disadvantage’, ‘Vulnerable/Impaired’ and ‘rely on others’) which together account for 57% of the variance in the responses.Analysis established that those with high self-reported transport problems were more likely to be located in fringe and remote parts of the city and lived in areas where it was not possible to walk to a local shop. However all groups made an average number of trips per day (except the ‘Vulnerable/Impaired’ group which make fewer trips) suggesting that self-reported transport disadvantage is unrelated to realised mobility. Analysis further established that only the ‘Vulnerable/Impaired’ group was associated with social exclusion and that they also had the lowest values of well-being compared to other groups.Overall findings confirm the methodological concerns associated with the use of self-reported measures of transport problems as a basis for defining transport disadvantage. The majority of those with high self-reported transport problems did not travel less than the survey sample as a whole and they were not associated with social exclusion. However the ‘Vulnerable/Impaired’ group was the exception, displaying a significantly higher association with social exclusion and lower well-being.The findings suggest which aspects of transport disadvantage are likely to be of greater concern for social policy. A concentration of research and policy on issues and social groups associated with the ‘Vulnerable/Impaired’ factor would be more effective in reducing social exclusion. Transport problems associated with this group including physical access to transport, knowing where to go and feeling safe from theft or attack when travelling may deserve higher priorities for attention. In addition those associated with the ‘Vulnerable/Impaired’ factor including older retired females and those who are more likely to be looking after someone with an illness or disability are clearly a high risk group and should warrant positive discrimination in transport and social policy.     

A supply chain-transport supernetwork equilibrium model with the behaviour of freight carriers

This paper presents a supernetwork equilibrium model integrating supply chain networks with a transport network, namely, a supply chain-transport supernetwork equilibrium model. The model takes into account the behaviour of freight carriers and transport network users to endogenously determine the transport costs generated in the supply chain networks. The interaction between transport network and supply chain networks can also be examined. Results of the numerical tests reveal that the improvement of transport network could enhance the efficiency of supply chain networks. The paper makes contributions to modelling of supply chain networks as well as to that of transport networks.     

Transportation and The International Trade of Eastern and Southern Africa

We use new data on transportation to determine its effect on the international trade of eastern and southern Africa (ESA). The effects were estimated with gravity models using alternative techniques to check for robustness. Freight forwarders provided information on freight charges (price), average duration of shipment (time) and variability in time. The new transportation variables and the more commonly used distance variable appear to have smaller effects overall than some previous research indicated, although our distance coefficient is identical to that of Coulibaly and Fotagné for West Africa. In contrast to other research critical of distance as a proxy for transport impediments, we find similar effects from distance and our measure of transport time, but both of these variables have significantly larger coefficients than price and variability. Landlocked ESA countries are twice as dependent on trade as the whole region after accounting for control variables, but they are not significantly more affected by changes in price and time, and they are less affected by distance and variability. The relative size of the time coefficients suggests that measures to lessen delays in shipping, for instance, faster border clearance, might encourage more trade than cost cutting measures that lowered price proportionately.     

我国运输行业上市公司企业社会责任信息披露情况研究

以我国A股上市交易的运输行业上市公司作为研究对象,运用描述性分析和多元线性回归方法对运输行业上市公司企业社会责任信息披露情况进行研究.研究结果表明:2008年我国运输行业上市公司社会责任信息披露比例较以前年度有显著提高,尤其是采用独立报告模式披露社会责任信息的企业数量显著增加;在企业社会责任信息披露的内容和方式上,节能减排等环境方面的信息披露比例有显著提高,但是在安全生产及债权人等方面的信息披露还有待加强;在公司特征方面,公司规模越大、盈利能力越强的上市公司越倾向于披露更多的企业社会责任信息,而且从地域分布上看,沪、深两地区企业的信息披露状况未显著好于其他地区的企业.

Transport biofuels in the European Union: The state of play

The implementation of the Biofuels Directive (2003/30/EC) in 25 member states is assessed here. Implementation problems are identified and analysed for the purpose of suggesting a way forward for biofuels policy in the European Union. Three main patterns are observed: effective implementation, formal compliance and weak implementation. Problems encountered in the policy process are both of a practical and more fundamental nature, i.e., due to a lack of consensus on the priority of competing policy objectives and disagreement on the suitability of first-generation biofuels for reaching the objectives. In this situation, stronger enforcement of targets does not appear to be a constructive way forward. Based on our analysis, we argue that the European Union should instead, and in agreement with the principle of subsidiarity, allow member states more flexibility.     

SeMS and sensibility: Security management systems and the management of risk in the Canadian Air Transport Security Authority

Following International Air Transportation Association requirement for all member airlines and airports to have a security management system (SeMS) beginning 1 March 2007, many organizations are looking to learn from safety and quality management systems. Without specific guidelines or best practices, organizations are forced to imitate these processes designed for different goals. Since safety, quality, and security environments operate on radically different principles, SeMS implementation must take a different tack. The case of the Canadian Air Transport Security Authority illustrates the importance of a custom-designed program that meets public and corporate needs. The Authority is responsible for security screening of passengers, non-passengers, and baggage within selected airports. As a crown corporation with a precise statutory mandate and regulatory environment, the development of a SeMS illustrates some of the key problems for the application of SeMS to larger organizations.
