R-Tresis: developing a transport model system for regional New South Wales

This paper sets out a demand modelling framework for the development of a regional transport and land use model system (R-Tresis), to be implemented for New South Wales (Australia). Traditionally, the focus of such a model system has been major metropolitan areas such as Sydney, where we have developed Tresis (Hensher, 2002). Given the growing concern about regional accessibility to many service classes, there is a need for a modelling capability that can be used to prioritize and guide policy decisions in regions that are often described as remote, rural, low density and small town. In developing a framework that is capable of integrating both demand and supply elements of transportation and land use activity, we recognized the challenges in developing primary data sources, and the high likelihood of a reliance on secondary data sources. This suggested an alternative approach to demand modelling that was not dependent on choice models; namely a suite of continuous choice models in which we capture the actual activities undertaken by each mode on both the demand and supply side at high spatial resolution.

Accounting for Infrastructure Service Delivery by Government: Generational Issues

Infrastructure service provision by government creates huge distributional issues about service availability and performance over time and the relative funding burdens borne by successive generations of consumers across time. But providing financial disclosure on these issues through inter-generational accounting pre-supposes that accounting measurement is both generationally neutral (temporal neutrality) and does not legitimate any particular pattern of distribution. At the very least, accounting measurements of service provision costs should possess the attribute of distributional fairness. They should not bias the inter-generational allocation of cost or funding burdens. We argue that the forced application of inappropriate commercial accounting concepts of asset valuation, depreciation and capital maintenance does produce significant generational bias. More flexibility is required to produce the necessary accounting measurement attributes for financial disclosure on whether government has discharged its continuing accountability for inter-generational equity in burden sharing. We discuss three conceptual issues and illustrate the need for flexibility by proposing an alternative 'flow of obligations' approach which does not require reference to valuations of community service resources or arbitrary cost allocations under depreciation.     

Carbon dioxide emissions and inland container transport in Taiwan

The aim of this study is to estimate the carbon dioxide (CO₂) emissions from inland container transport during the time period of 1998-2008 and predicts the trend of these emissions. The analyses show that the CO₂ emission from inland container transport in 1992 reached 1.03 million tonnes, and the figure drastically increased by 89.3% to 1.95 million tonnes in 2008. Using a multiple regression model, gross domestic product (GDP) and oil price are found to be the key drivers for CO₂ emission. The CO₂ mitigation strategies are discussed in the policy suggestions given that Taiwan is warming at twice global average rate.

乳化降粘对管道输送的影响

本文通过分析小河原油的输送情况,提出向原油中添加乳化降剂来降低原油粘度进行输送,而合适的加入条件是提高降粘效率的关键。通过乳化降粘剂的实验研究,对原油温度、含水率、降粘剂用量等对降粘效率影响等因素进行了分析。得出乳状液加入浓度选用0.5%,输送温度选择40℃⁵0℃,含水量选在40%50℃,含水量选在40%⁶0%时为宜。

What India Can Learn from China and Vice Versa

A partial convergence of the Indian and Chinese growth models is likely. Judging from China's experience, sustaining India's impressive economic performance of recent years will require a significant further opening of its economy (externally and internally), higher savings and investments, especially in physical infrastructure and social services, and stronger labor absorption in the modern sectors. The base of India's current economic boom - software, IT-related services and high-end manufacturing - is narrow compared to China's. Poor performance in agriculture is responsible for still significant poverty in many parts of rural India. Bilateral India-China ties, including trade and investment, are increasing rapidly and could help to bring about the structural economic changes India needs. Through its exports to China, India is becoming linked to global supply chains centered on China. The notion that India-China relations are, or are bound to become, fundamentally antagonistic, held by many in the USA, is mistaken and potentially dangerous.
