Multilingualism and local-global identities: Japanese language education in rural Australia

The purpose of this article is to examine the value accruing to a regional area in Australia from the location of an undergraduate Japanese language education program in a university in that area. The focus is on the manner in which the inclusion of such a program enhances the sustainability of the area. Sustainability is here defined as the resilience demonstrated by social subjects in the absence of the full range of services available in more densely populated and resource advantaged areas. Such resilience implies an ongoing capacity on the part of subjects to contribute productively to social and economic networks in the area. The discussion includes two cases of graduates of the program under review. On the basis of these cases, the argument is advanced that local regional and rural area access to a tertiary sector second language program offers a unique and valuable strategic dimension to the personal and professional development of social agents in regional areas and to the sustainability of these areas generally.

The importance of forest area and configuration relative to local habitat factors for conserving forest mammals: A case study of koalas in Queensland, Australia

The loss and fragmentation of forest habitats by human land use are recognised as important factors influencing the decline of forest-dependent fauna. Mammal species that are dependent upon forest habitats are particularly sensitive to habitat loss and fragmentation because they have highly specific habitat requirements, and in many cases have limited ability to move through and utilise the land use matrix. We addressed this problem using a case study of the koala (Phascolarctos cinereus) surveyed in a fragmented rural-urban landscape in southeast Queensland, Australia. We applied a logistic modelling and hierarchical partitioning analysis to determine the importance of forest area and its configuration relative to site (local) and patch-level habitat variables. After taking into account spatial auto-correlation and the year of survey, we found koala occurrence increased with the area of all forest habitats, habitat patch size and the proportion of primary Eucalyptus tree species; and decreased with mean nearest neighbour distance between forest patches, the density of forest patches, and the density of sealed roads. The difference between the effect of habitat area and configuration was not as strong as theory predicts, with the configuration of remnant forest becoming increasingly important as the area of forest habitat declines. We conclude that the area of forest, its configuration across the landscape, as well as the land use matrix, are important determinants of koala occurrence, and that habitat configuration should not be overlooked in the conservation of forest-dependent mammals, such as the koala. We highlight the implications of these findings for koala conservation. (c) 2006 Elsevier Ltd. All rights reserved.

TV REGIONAL NO VALE DO PARAÍBA - SP: expansão, aspectos da audiência e modos de inserção local

Investigação sobre a regionalização das redes de comunicação, em especial a televisão, fenômeno que representa uma realidade de segmentação da comunicação massiva. Objetiva-se analisar e classificar as emissoras regionais de televisão com relação aos seus modos de inserção local, observando-se suas especificidades, programação, estratégias de comunicação e ações de conquista de identidade com a comunidade onde estão inseridas, além de tentar compreender como se deu a expansão da televisão nessa região, desde a implantação da primeira emissora, em 1988, na cidade de São José dos Campos SP. Tomando-se como recorte de estudo, as emissoras de televisão regional de sinal aberto no Vale do Paraíba, estado de São Paulo, foram realizadas entrevistas semi-abertas com profissionais das áreas comercial e de programação das mesmas e aplicados questionários junto a uma amostra da população do Vale do Paraíba que representa os telespectadores potenciais da área de cobertura dessas emissoras, a fim de se identificar a percepção que o público receptor tem a respeito da presença e atuação das televisões locais. Conclui-se que os diferentes modos de inserção local das emissoras influem diretamente na relação de identidade das mesmas com os telespectadores da região.(AU)

Equilibration through local information exchange in networks

We study the equilibrium states of energy functions involving a large set of real variables, defined on the links of sparsely connected networks, and interacting at the network nodes, using the cavity and replica methods. When applied to the representative problem of network resource allocation, an efficient distributed algorithm is devised, with simulations showing full agreement with theory. Scaling properties with the network connectivity and the resource availability are found. © 2006 The American Physical Society.

Packet switching in wide area broadband private networks

B-ISDN is a universal network which supports diverse mixes of service, applications and traffic. ATM has been accepted world-wide as the transport technique for future use in B-ISDN. ATM, being a simple packet oriented transfer technique, provides a flexible means for supporting a continuum of transport rates and is efficient due to possible statistical sharing of network resources by multiple users. In order to fully exploit the potential statistical gain, while at the same time provide diverse service and traffic mixes, an efficient traffic control must be designed. Traffic controls which include congestion and flow control are a fundamental necessity to the success and viability of future B-ISDN. Congestion and flow control is difficult in the broadband environment due to the high speed link, the wide area distance, diverse service requirements and diverse traffic characteristics. Most congestion and flow control approaches in conventional packet switched networks are reactive in nature and are not applicable in the B-ISDN environment. In this research, traffic control procedures mainly based on preventive measures for a private ATM-based network are proposed and their performance evaluated. The various traffic controls include CAC, traffic flow enforcement, priority control and an explicit feedback mechanism. These functions operate at call level and cell level. They are carried out distributively by the end terminals, the network access points and the internal elements of the network. During the connection set-up phase, the CAC decides the acceptance or denial of a connection request and allocates bandwidth to the new connection according to three schemes; peak bit rate, statistical rate and average bit rate. The statistical multiplexing rate is based on a `bufferless fluid flow model' which is simple and robust. The allocation of an average bit rate to data traffic at the expense of delay obviously improves the network bandwidth utilisation.

An area localization scheme for large scale underwater wireless sensor networks

In this paper, we study an area localization problem in large scale Underwater Wireless Sensor Networks (UWSNs). The limited bandwidth, the severely impaired channel and the cost of underwater equipment all makes the underwater localization problem very challenging. Exact localization is very difficult for UWSNs in deep underwater environment. We propose a Mobile DETs based efficient 3D multi-power Area Localization Scheme (3D-MALS) to address the challenging problem. In the proposed scheme, the ideas of 2D multi-power Area Localization Scheme(2D-ALS) [6] and utilizing Detachable Elevator Transceiver (DET) are used to achieve the simplicity, location accuracy, scalability and low cost performances. The DET can rise and down to broadcast its position. And it is assumed that all the underwater nodes underwater have pressure sensors and know their z coordinates. The simulation results show that our proposed scheme is very efficient. © 2009 IEEE.
