The success of tree establishment on both saline and non-saline sites is dependent on the use of appropriate pre- and post-planting procedures. The 4 trials reported here on 2 dryland saline sites, near Wellington and Young in New South Wales, deal with the individual and combined effects of mulch, fertiliser, tree guards and pre-conditioning with salt and waterlogging, alone and in combination, on survival and growth of Acacia stenophylla, Atriplex nummularia, Casuarina cunninghamiana, Eucalyptus camaldulensis and Melaleuca halmaturorum. Each trial included 1 or more of these species. Soil salinity was assessed at the plot level using a hand-held electromagnetic induction device (EM38). Treatments had variable effects, depending on species, site, experiment and treatment combinations. Mulch application significantly improved height in 2 trials and, in combination with plastic guard and fertiliser, produced the best results. Treatments generally increased basal stem diameter or stem diameter at breast height, and crown volume, but the differences were usually not statistically significant. The combined effect of mulch, fertiliser and plastic guard on growth was usually greater than any single treatment.

Pastures are the basis of most forms of agricultural production on the New South Wales central and southern tablelands. Pastures occupy the bulk of the region's landmass and pasture-based livestock production annually contributes more than three-quarters of the regional gross value of rural production. Throughout the region, there is substantial variation in pasture composition, ranging from high quality introduced perennial grasses and legumes to pastures comprising mainly low quality native species. This paper examines the economics of the main categories of temperate pastures over a range of soil fertility-rainfall environments on the south-eastern tablelands areas of New South Wales. Using a linear programming model and discounted development budgets, the results demonstrate the strong influence of the environment on the economics of the individual pasture systems. The highest economic returns in both the short and longer-terms were to the introduced perennial grass pastures in most of the environments. Pastures based on introduced legumes and the high quality native species also generated sound economic returns, although there are recognised problems with the persistence of the legume pastures. Over time, the returns to the better quality native pastures compare favourably with the introduced legumes and are better suited to acidic soils than the perennial grasses. Low quality native species produced relatively poor economic returns in all environments and unfortunately, are the main pasture type in the region's less favourable environments.

AbstractData is presented on textural variation, optical properties, and resultant compositions of the olivines from a differentiated teschenite sill. The range in olivine composition is from Fa21 to Fa,60. Both the individual crystals and successive crops of crystals become more fayalitic with progressive differentiation.

This paper focuses on teacher attitudes to educational provisions for gifted and talented children in two countries. A questionnaire was distributed to 100 teachers in Sydney, New South Wales and to 100 teachers in Essex, England. Both groups represented a range of primary and secondary schools. Teachers had between 5 and 20 years experience and most were aged between 30 and 40 years. The common factor was acceptance of provisions within the comprehensive framework of education but rejection of any provisions that might be interpreted as elitist. It was also considered that there should be pre-service and in-service training in teaching methods for gifted education for all teachers so that the individual talents of children can be accommodated according to their needs within the comprehensive system.

Differences in concentrations of n-alkanes in the cuticular waxes of plants can be used to estimate the species composition of herbage mixtures or the diet consumed by grazing animals. The objectives of this study were (i) to provide information on the n-alkane (C25-C35) ‘signatures’ or patterns of pasture species occurring in ‘degraded’ and perennial pastures of the Northern Tablelands, New South Wales, and (ii) to examine the extent of the field variation in the signatures. There were considerable differences in odd-numbered alkanes and in their total content between species. There were also significant differences in n-alkane concentrations among species within grasses, legumes, and weeds. For the individual odd-numbered alkanes, differences between species accounted for 87-93% of the total variance in alkane concentration over 3 samplings. Variable results for the temporal effect suggest that time-specific herbage samples are needed in animal diet studies. Analyses of the spatial effect indicate that random cuts over each treatment plot can obtain representative samples of each species. Multivariate statistical analyses using principal component and discriminant analyses indicated that the patterns of alkanes in species occurring on both degraded and perennial pastures were readily distinguishable. These results confirmed that the alkane technique could be used for estimation of diet composition in grazing sheep on the Northern Tablelands, NSW, where differences in n-alkane signatures between species were sufficient and persistent over time.

The law of parliamentary privilege in New South Wales is the sum of certain immunities, rights, and powers enjoyed by the individual Houses of the Parliament of New South Wales, together with their members and committees, as constituent parts of the Legislature. The law is complex. It is liberally interspersed with uncertainty and ambiguity. It is also distinctly different from the law of privilege in other Australian jurisdictions, including the Commonwealth, and also from overseas jurisdictions. It is singular in the degree to which it relies on the common law, without recourse to statutory expression or to the historical privileges of the Houses of Parliament in the United Kingdom. Nevertheless, in some respects, the Parliament of New South Wales has been remarkably successful through the courts, and through its own procedures, in asserting the powers and rights of members under the banner of parliamentary privilege, notably in relation to orders for the production of State papers.

The comparative study of roadside memorials in New South Wales, Australia, and Texas, United States, raises questions about the consistency in memorial form and practice between societies with diverse ethnic and religious profiles and different historical backgrounds. This article compares roadside memorials in two societies, and suggests that ethnic and sub-group affiliation accounts for local and individual differences in what is essentially an international phenomenon powered by developments in motoring culture, postmodernism, and globalization. The roadside memorial reclaims public space for the celebration of the individual in a period and place of overwhelming technological and cultural change.

Police misuse of strip search powers at music festivals, at train stations, in police vehicles and at other locations has been subject to sustained public attention in recent years. This article traces the evolution of strip search practices in New South Wales, explores the legal and policy context in which they have developed, highlights the individual and social harms arising from them and discusses the need for fundamental law reform. We argue that recent controversies regarding police strip searches and drug detection dog operations in New South Wales show policing to be simultaneously a law-making and a law-abusing power. By examining concepts concerned with how police construct their own working rules, police data and testimony provided to the Law Enforcement Conduct Commission (LECC), we explain how police justify conducting strip searches that should otherwise be considered unlawful.
