Adaptation and management of Australian buffalograss cultivars for shade and water conservation

Soft-leaf buffalo grass is increasing in popularity as an amenity turfgrass in Australia. This project was instigated to assess the adaptation of and establish management guidelines for its use in Australias vast array of growing environments. There is an extensive selection of soft-leaf buffalo grass cultivars throughout Australia and with the countrys changing climates from temperate in the south to tropical in the north not all cultivars are going to be adapted to all regions. The project evaluated 19 buffalo grass cultivars along with other warm-season grasses including green couch, kikuyu and sweet smother grass. The soft-leaf buffalo grasses were evaluated for their growth and adaptation in a number of regions throughout Australia including Western Australia, Victoria, ACT, NSW and Queensland. The growth habit of the individual cultivars was examined along with their level of shade tolerance, water use, herbicide tolerance, resistance to wear, response to nitrogen applications and growth potential in highly alkaline (pH) soils. The growth habit of the various cultivars currently commercially available in Australia differs considerably from the more robust type that spreads quicker and is thicker in appearance (Sir Walter, Kings Pride, Ned Kelly and Jabiru) to the dwarf types that are shorter and thinner in appearance (AusTine and AusDwarf). Soft-leaf buffalo grass types tested do not differ in water use when compared to old-style common buffalo grass. Thus, soft-leaf buffalo grasses, like other warm-season turfgrass species, are efficient in water use. These grasses also recover after periods of low water availability. Individual cultivar differences were not discernible. In high pH soils (i.e. on alkaline-side) some elements essential for plant growth (e.g. iron and manganese) may be deficient causing turfgrass to appear pale green, and visually unacceptable. When 14 soft-leaf buffalo grass genotypes were grown on a highly alkaline soil (pH 7.5-7.9), cultivars differed in leaf iron, but not in leaf manganese, concentrations. Nitrogen is critical to the production of quality turf. The methods for applying this essential element can be manipulated to minimise the maintenance inputs (mowing) during the peak growing period (summer). By applying the greatest proportion of the turfs total nitrogen requirements in early spring, peak summer growth can be reduced resulting in a corresponding reduction in mowing requirements. Soft-leaf buffalo grass cultivars are more shade and wear tolerant than other warm-season turfgrasses being used by homeowners. There are differences between the individual buffalo grass varieties however. The majority of types currently available would be classified as having moderate levels of shade tolerance and wear reasonably well with good recovery rates. The impact of wear in a shaded environment was not tested and there is a need to investigate this as this is a typical growing environment for many homeowners. The use of herbicides is required to maintain quality soft-leaf buffalo grass turf. The development of softer herbicides for other turfgrasses has seen an increase in their popularity. The buffalo grass cultivars currently available have shown varying levels of susceptibility to the chemicals tested. The majority of the cultivars evaluated have demonstrated low levels of phytotoxicity to the herbicides chlorsulfuron (Glean) and fluroxypyr (Starane and Comet). In general, soft leaf buffalo grasses are varied in their makeup and have demonstrated varying levels of tolerance/susceptibility/adaptation to the conditions they are grown under. Consequently, there is a need to choose the cultivar most suited to the environment it is expected to perform in and the management style it will be exposed to. Future work is required to assess how the structure of the different cultivars impacts on their capacity to tolerate wear, varying shade levels, water use and herbicide tolerance. The development of a growth model may provide the solution.

Healthy hardwoods. A field guide to pests, diseases and nutritional disorders in subtropical hardwoods.

Healthy hardwoods: A field guide to pests, diseases and nutritional disorders in subtropical hardwoods can be used to help identify the common damaging insects, fungi and nutritional disorders in young eucalypt (Eucalyptus and Corymbia species) plantations in subtropical eastern Australia. This guide includes photographs of each insect, fungus and nutritional disorder and the damage they cause, along with a brief description to aid identification. A brief host list for insects and fungi, including susceptibility and occurrence, is provided as a guide only. A hand lens will be useful, especially to identify fungi. Although it is possible to identify insects and fungi from these photographs, laboratory examination will sometimes be necessary. For example, microscopes and culturing media might be used to identify fungi. Information about four exotic pests and diseases has also been included in the Biosecurity threats chapter. Potentially, these would have a severe impact on plantation and natural forests if introduced into Australia. To prevent establishment of these pests, early detection and identification is crucial. If an exotic insect or disease is suspected, then an immediate response is required. Usually, the first response will be to contact the nearest Australian Quarantine and Inspection Service office or forestry agency to seek advice.

Acceptance and leadership-hegemonies of e-commerce policy perspectives

This paper presents an analysis of the e-Commerce policies developed and implemented in the USA, Canada, Australia, Victoria, Finland, Norway, the UK, Ireland, the EU (by the OECD), Singapore, Japan, Malaysia, Thailand and Hong Kong (Special Administrative Region). The paper shows that e-Commerce policy adopted is generally trying to achieve two fundamental aims:

1. to minimize regulatory environments for e-Commerce; and
2. to ease logistical problems in doing e-Commerce—i.e. in paying electronically, in deliver y of goods and in customs, tariffs and duties.

These strategies are designed to create an environment where e-Commerce is adopted by business and government in these countries to achieve ‘best practice’, to become ‘modern’, to gain ‘efficiencies’, because ‘it is the way to go’, because ‘we must have it, because everybody has it’, and because they ‘perceive the benefits of it’. In essence it is being used to gain hegemony in the economic competitiveness of the geopolitical environment created by the Internet. This paper argues that differentiating types of policy is related to ideology and hegemony in the various countries.

Teaching teachers : building a post-compulsory education training and employment sector through teacher education

This paper captures development of the GDAL as understood by its instigators as a platform for reform. The GDAL would respond to the challenge being put before education and training providers to prepare young people to create and engage with a learning society through their capacity for lifelong learning. These teacher education students would, ideally, bring skills and knowledge already gained in a professional career. While they would gain teacher registration they were better conceptualized as professional educators for an emerging post compulsory education, training and employment sector: it was expected that graduates would not only teach in schools but would also move readily within the network of learning spaces that young people increasingly experience in their formal education. In the process, they would be a force for change, seeding reform within secondary schools. As a 'teacher' these graduates would have the credibility to challenge the entrenched practices of other teachers. It is the story of 'what happened' as a consequence of this specific aim that I am telling today.

Knowledge and attitudes of ED staff before and after implementation of the emergency nurse practitioner role

Introduction
The Emergency Nurse Practitioner (ENP) role was implemented in the Emergency Department (ED) at The Northern Hospital (TNH) in April 2004. Implementation of the ENP role occurred as part of a Department of Human Services funded project to establish the ENP model as an effective and sustainable model of care delivery in Victorian EDs.

Aim
The aim of this study was to examine the attitudes and knowledge of ED medical and nursing staff prior to, and following, implementation of the ENP role.

Methods
The design was a pre-test/post-test design and the Northern Emergency Nurse Practitioner Staff Survey was used for data collection. A total of 104 ED staff completed the pre-test survey and the post-test survey was completed by 79 ED staff.

Results
The attitudes and knowledge of ED medical and nursing staff changed significantly during implementation of the ENP role. Pre-test data indicated that staff were generally supportive of the role but had a poor understanding of the requirements for endorsement and how the role would function in clinical practice. Post-test data showed significant increases in support for the ENP role, a greater understanding of the requirements to become an ENP and increased understanding of the logistics and functions of an ENP.

Conclusion
The implementation of the Nurse Practitioner role within the emergency department of The Northern Hospital, Victoria Australia has been a positive experience for both medical and nursing staff.

A new definition of 'Museum'

At the national AGM of Museums Australia held on 22 Mar ch 2002, our association adopted a new definition of ‘museum’. This article aims to provide members and other readers with an understanding of the background to the change, and the potential offered to our sector by the new definition.

Warrnambool's Wesleyan heritage, 1847-1977

The thesis is about Methodism in Warrnambool. The key argument is that the Wesleyan heritage, so important to the early Wesleyan pioneers, continued to shape the life of the Warrnambool Methodist Church and was perpetuated by its leaders, in particular its local lay leaders, for a period of 130 years.
