Regulation of train service by coasting control in metro railway system

To maximise the capacity of the rail lineand provide a reliable service for pas-sengers throughout the day, regulation of train service to maintain steady service headway is es-sential. In most current metro systems, train usually starts coasting at a fixed distance from the departed station to achieve service regulation. However, this approach is only effective with re-spect to a nominal operational condition of train schedule but not necessarily the current service demand. Moreover, it is not simply to identify the necessary starting point for coasting under the run time constraints of current service conditions since train movement is attributed by a large number of factors, most of which are non-linear and inter-dependent. This paper presents an ap-plication of classical measures to search for the appropriate coasting point to meet a specified inter-station run time and they can be integrated in the on-board Automatic Train Operation (ATO) system and have the potential for on-line implementation in making a set of coasting command decisions.

The regulation of insurance intermediaries in the Australian financial services market

The insurance industry discharges a critical role in the Australian economy and is a significant part of the Australian financial services market. The industry relies upon intermediaries, the principal types being brokers and agents, to promote, arrange and distribute their products and services in the market. The pivotal role that they play in this context and sensitivities associated with the consumer oriented products, such as house and contents insurance, has ensured close regulatory attention. Of particular importance was the passage of the Insurance (Agents and Brokers) Act 1984 (Cth), a comprehensive attempt to address the responsibilities of intermediaries as well as particular problem areas associated with the handling of money. However, with the introduction of financial services and market reform early in the new millennium this insurance intermediary specific regulatory approach was abandoned in favour of a market-wide strategy; that is, market reform was based upon across-the-board licensing, disclosure, conduct and fairness standards, and all financial products and services are now regulated at a generic level under Ch 7 of the Corporations Act 2001 (Cth). This article briefly explores the categories of insurance intermediaries and the relevant distinctions between them but focuses mainly upon the regulatory context in which they operate. This context transcends a strictly legal framework as the regulatory body, the Australian Securities and Investments Commission (ASIC), has sought to inform and guide the market through Policy Statements and Regulatory Guides. The usefulness of these guides as an adjunct to the legislation in explaining the scope and operation of regulatory framework is examined. In addition, the article looks at the self-regulatory and dispute resolution practices in this area and their impact. In conclusion an assessment of this across-the-board regulatory regime is advanced.

TaNF-YB3 is involved in the regulation of photosynthesis genes in Triticum aestivum

Nuclear Factor Y (NF-Y) transcription factor is a heterotrimer comprised of three subunits: NF-YA, NF-YB and NF-YC. Each of the three subunits in plants is encoded by multiple genes with differential expression profiles, implying the functional specialisation of NF-Y subunit members in plants. In this study, we investigated the roles of NF-YB members in the light-mediated regulation of photosynthesis genes. We identified two NF-YB members from Triticum aestivum (TaNF-YB3 & 7) which were markedly upregulated by light in the leaves and seedling shoots using quantitative RT-PCR. A genome-wide coexpression analysis of multiple Affymetrix Wheat Genome Array datasets revealed that TaNF-YB3-coexpressed transcripts were highly enriched with the Gene Ontology term photosynthesis. Transgenic wheat lines constitutively overexpressing TaNF-YB3 had a significant increase in the leaf chlorophyll content, photosynthesis rate and early growth rate. Quantitative RT-PCR analysis showed that the expression levels of a number of TaNF-YB3-coexpressed transcripts were elevated in the transgenic wheat lines. The mRNA level of TaGluTR encoding glutamyl-tRNA reductase, which catalyses the rate limiting step of the chlorophyll biosynthesis pathway, was significantly increased in the leaves of the transgenic wheat. Significant increases in the expression level in the transgenic plant leaves were also observed for four photosynthetic apparatus genes encoding chlorophyll a/b-binding proteins (Lhca4 and Lhcb4) and photosystem I reaction center subunits (subunit K and subunit N), as well as for a gene coding for chloroplast ATP synthase  subunit. These results indicate that TaNF-YB3 is involved in the positive regulation of a number of photosynthesis genes in wheat.

The international regulation of sustainable forest management : doctrinal concepts, governing institutions and implementation

The overarching objective of the research was to identify the existence and nature of international legal principles governing sustainable forest use and management. This research intended to uncover a set of forest legal considerations that are relevant for consideration across the globe. The purpose behind this, is to create a theoretical base of international forest law literature which be drawn upon to inform future international forestry research. This research will be of relevance to those undertaking examination of a particular forest issue or those focusing on forests in a particular region. The thesis explains the underlying legal issues in forest regulation, the dominant international regulatory approaches and makes suggestions as to how international and national forest policy could be improved.

A changing landscape : The mortgagee's power of sale in Queensland

In Australia, the extent of a mortgagee’s duty when exercising power of sale has long been the subject of conjecture. With the advent of the global financial crisis in the latter part of 2008, there has been some concern to ensure that the interests of mortgagors are adequately protected. In Queensland, concern of this type resulted in the enactment of the Property Law (Mortgagor Protection) Amendment Act 2008 (Qld). This amending legislation operates to both extend and strengthen the operation of s 85 of the Property Law Act 1974 (Qld) which regulates the mortgagee’s power of sale in Queensland. This article examines the impact of this amending legislation which was hastily introduced and passed by the Queensland Parliament without consultation and which introduces a level of prescription in relation to a sale under a prescribed mortgage which is without precedent elsewhere in Australia.
