Changes in vegetation sand floristics under a powerline easement and implications for vegetation management

Utility corridors such as powerlines are widespread linear easements of highly modified vegetation which often fragment natural areas of conservation significance. Vegetation management along these easements is aimed at modifying vegetation structure by the removal of all tall shrubs and trees, which may have adverse impacts on flora and fauna diversity. Victoria's Bunyip State Park is bisected by a high voltage powerline easement which is managed by a four year slashing cycle. Repeated slashing has altered plant species composition and structure of the drier slope and ridge vegetation compared to unslashed adjacent Open Forest vegetation, but Wet Heath within the management zone has remained largely unmodified. At a broad level, plant species diversity in the easement is increased, and higher vegetation density has created small mammal habitat. The powerline easement did not appear to facilitate weed invasion. Vegetation management by repeated slashing has altered the vegetation, but does not appear to have had adverse conservation impacts on local plant and small mammal diversity.

Ecological attributes of strategic land acquisitions for addition to Victoria's public protected area estate : 2004-2005

The development of a comprehensive, adequate and representative reserve system is the key objective of the National Reserve System, and is supported by all Australian States and Territories. In Victoria, the purchase of private land for incorporation into the parks and reserves system assists in the protection of some of the State’s most endangered ecosystems. This article outlines the ecological attributes of private land purchased for addition to the Victorian public protected area system between 2004 and 2005.

Easier analysis and better reporting : modelling ordinal data in mathematics education research

This article presents an examination of the use of Rasch modelling in a major research project, 'Improving Middle Years Mathematics and Science' (IMYMS). It is unarguable that it is important to take students' perceptions, or views, into account when planning learning and teaching for them. The IMYMS student perceptions survey is an attempt to make visible these student viewpoints, and report them in a way that is accessible to teachers and researchers involved in the project. The project involves four clusters of schools from urban and regions of Victoria to investigate the role of mathematics and science knowledge and subject cultures in mediating change processes in the middle years of schooling. There are five secondary and twenty-eight primary schools. The project has generated both qualitative and quantitative data, with much of the qualitative data being ordinal in nature. Reporting the results of analyses for a range of audiences necessitates careful, well-designed report formats. Some useful new report formats based on Rasch modeling -the Modified Variable Map, the Ordinal Map, the Threshold Map, and the Annotated Ordinal Map - are illustrated using data from the IMYMS project. The Rasch analysis and the derived reporting formats avoid the pitfalls that exist when working with ordinal data and provide insights into the respondents' views about their experiences in schools unavailable by other approaches.

The contextual nature of the market orientation and organisational performance relationship: an Australian and New Zealand study

As part of a broader study of the relationship between traditional and online marketing mix elements and organisational performance, the study reported in this paper utilised structural equation modelling to examine the relationship between market orientation and organisational performance. The study found that there was an insignificant relationship between market orientation and organisational performance, thereby lending support to studies conducted in the UK, Ghana, and the US (since the studies in the US by Narver and Slater (1990)), which found that there may be a contextual nature to the relationship between the two constructs. The study, therefore, does not support Pulendran et al. (2000).

Public satisfaction with police : using procedural justice to improve police legitimacy

Policing research and theory emphasises the importance of supportive relationships between police and the communities they serve in increasing police effectiveness in reducing crime and disorder. A key reason people support police is that they view police as legitimate. The existing research literature, primarily from the United States, indicates that the most important factor in public assessments of police legitimacy is procedural justice. The present study is the first in an Australian jurisdiction to examine the effect of procedural justice and police legitimacy on public satisfaction with police. Using responses to a large postal survey (n = 2611), findings show that people who believe police use procedural justice when they exercise their authority are more likely to view police as legitimate, and in turn are more satisfied with police services. This study differs to US-based research in the greater importance of people's evaluations of instrumental factors in judgments of police legitimacy. The findings are important as they confirm that people's assessments of fair and effective policing in Australia will be enhanced by policing strategies that emphasise the use of procedural justice in encounters with the public.

Complexes of the tripodal nitrilotrimethylenetrisphosphonic (H6L) and P,P',P''-triphenylnitrilotrimethylenetrisphosphinic (H3L) acids with the copper(II) ion. Synthesis and charaterization of [Hpy][Cu(H3L)(H2O)] and [Cu(HL)(py)]2.2Me2CO

The complexes [Hpy][Cu(H₃L)(H2O)] 1 (L⁶ = nitrilotrimethylenetrisphosphonate) and [Cu(HL°)(py)]₂·2Me₂CO 2 [(L°)³ = P,P,P" -triphenylnitrilotrismethylenetrisphosphinate)] have been isolated and characterized by X-ray crystallography, near IR-visible spectroscopy and magnetic measurements. The structure determination has shown the complexes to be constituted by monomeric and dimeric units respectively. In the monomer the metal atom is surrounded by the phosphonate ligand and a water molecule, with a geometry between a trigonal bipyramid and a square pyramid. The two copper atoms in the dimer are held together by an arm of the tripod ligand, with a pyridine molecule as additional ligand, and display octahedral geometry. The presence of monomeric and dimeric species in aqueous solutions of 1 and 2 has been shown by ESMS studies. The formation in water solution of the dimer [{Cu(H₃L)}₂]^2-, as a minor species, has been supported by potentiometric measurements, whereas only the monomeric anion [CuL°] has been ascertained to be present. In general the ligand H₃L° forms less stable copper(II) complexes than H₆L.

Observations of the ecological impacts of Sambar Cervus unicolor in East Gippsland, Victoria, with reference to destruction of rainforest communities

Damage caused by Sambar, particularly browsing, antler rubbing and physical removal of particular plant species, is resulting in serious ecological consequences. Threatening processes instigated or maintained by Sambar include: loss of individual taxa, altered vegetation structure and massive
widespread removal and prevention of regeneration, which is now resulting in the loss of plant communities in some areas. These observations are particularly disturbing, as it is apparent that Sambar are yet to reach their full ecological and population potential in south-eastern Australia. The destruction documented ill this article is now so widespread and so severe that in places it represents an ecological disaster for specific plant and animal species, ecological vegetation classes and floristic communities. We strongly recommend that Sambar in particular, and feral deer in general. should no longer be protected under the Wildlife Act 1975 so that control methods can be devised and implemented. It now appears that such measures will he essential for the long-term survival of some fragile plant species and communities in Victoria. (Title: Victorian Naturalist 122(4) 2005, 189-200

A cross-national comparison of risk and protective factors for adolescent substance use : the United States and Australia

Purpose
To compare risk and protective factors that influence youth substance use in Australia and the United States. The two countries have different policy orientations toward substance use: Australia has adopted harm-reduction policies, and the United States has adopted abstinence-focused polices.

Methods
Cross-sectional survey data were collected from independent samples of adolescents in the states of Maine (N = 16,861; 53% female, 7% Non-white) and Oregon (N = 15,542; 51% female, 24% Non-white) in the United States and Victoria in Australia (N = 8442; 54% Female, 11% Non-white) in 1998 (Maine and Oregon) and 1999 (Victoria). Chi-square tests, t-tests, effect size comparisons, and logistic regression analyses that accounted for age and gender were used to investigate cross-national similarities and differences in: (a) rates of cigarette, alcohol, and marijuana use; (b) levels of risk and protective factors; and (c) magnitudes of associations between risk and protective factors and substance use.

Results
More adolescents in Victoria reported using cigarettes and alcohol, whereas more of the U.S. adolescents reported using marijuana. Exposure to risk and protective factors was generally similar in the cross-national samples. However, adolescents in Maine and Oregon perceived handguns to be more readily available, reported more participation in religious activities, and were higher in sensation-seeking and social skills; and adolescents in Victoria had more favorable attitudes toward drug use and reported community norms and parental attitudes more favorable to drug use. Most of the risk and protective factors were strongly associated with substance use to a similar degree in Victoria, Maine, and Oregon. However, among adolescents in Maine and Oregon peer/individual risk and protective factors associated with social detachment were more strongly related to substance use, and among adolescents in Victoria, family protective factors were less strongly related to alcohol use.

Conclusions
Inter-country influences on youth substance use are generally similar despite different policy directions. Existing differences suggest that the abstinence policy context is associated with higher levels of illicit drug use and stronger relations between individual indicators of social detachment and substance use, whereas the harm reduction policy context is related to more cigarette and alcohol use, possibly from exposure to normative influences that are more tolerant of youth drug use.

The use of codes of ethics in the corporate marketplace: the case of Australia and Sweden

Business ethics is a subject that recently has been thrust again into prominence in industrialised economies around the world, due to the revelations of the practices of some of the major corporations operating within the USA. In Australia, corporate collapses such as HIH and Onetel and in Sweden, the scandals with the top executives of Skandia and also Systembolaget have brought in to sharp focus that these practices are not confined to the USA. Since the early 1960s, codes of ethics have been in evidence in many organisations in the USA, whilst in Australia, as in Britain, the interest in codes of ethics was piqued by the stock market crash of 1987. In Sweden, however, this concept of the use of codes of ethics in the corporate sector had not been investigated prior to this study. This paper examines the use of codes of ethics in the marketplace by the top companies operating in corporate Australia and corporate Sweden. The outcome of this research shows that in both Australia and Sweden that large organisations indicate a substantial interest in codes of ethics and value the use of their codes in the marketplace. There are, however, differences in the ways that the companies in each country implement their codes of ethics in the marketplace and the benefits that they see as being derived from them.

Self-determination theory and needs satisfaction in marketing education : are we meeting the needs of students in large marketing classes?

The aim of this study is to assess whether universities are meeting the needs of students in large marketing classes. In so doing the study investigates the application of self determination theory and psychological needs satisfaction. The basic needs scale, comprising of three constructs; Control, Competence and Caring was adapted and used to evaluate students’ perception of an introductory marketing subject. The study used a multi-method approach consisting of a literature review, a qualitative phase involving in-depth interviews with marketing teaching staff and focus groups with marketing students and a survey of students about introductory level marketing. An adapted version of the basic psychological needs scale was included in a questionnaire that was administered to a convenience sample of 366 students. MANOVA, ANOVA and descriptive statistics were used to analyse the data. The results show that the psychological needs satisfaction of many students are not being fully realised. It was also found that marketing degree students enjoyed the challenges and were more stimulated by the subject. The higher achieving students enjoyed the challenge of the subject more than the lower achieving students. As a result of this study, there are three suggestions for further research. Firstly, further study should compare subjects, with relatively small enrolments, to those with large enrolments to corroborate the value of this method of assessing student satisfaction. Secondly, the use of a larger sample across other universities would confirm whether these findings hold for other institutions. Finally, it is suggested that a structural model should be developed to extend this investigation of student satisfaction and the constructs used in the study.

Information warfare : corporate attack and defence in a digital world

This text introduces the concepts of information warfare from a non-military, organizational perspective. It is designed to stimulate managers to develop policies, strategies, and tactics for the aggressive use and defence of their data and knowledge base. The book covers the full gambit of information warfare subjects from the direct attack on computer systems to the more subtle psychological technique of perception management. It provides the framework needed to build management strategies in this area. The topics covered include the basics of information warfare, corporate intelligence systems, the use of deception, security of systems, modes of attack, a methodology to develop defensive measures, plus specific issues associated with information warfare.

Reviewing the learning organisation model in a child and adolescent mental health service

From 1995 onwards, a child and adolescent mental health service (CAMHS) applied Senge's learning organisation model. This review compared service performance with that of peer services 5 years later and explored whether any differences were associated with the application of this model. The comparison methodology used quantitative analysis of external data from the Department of Human Services, together with qualitative analysis of material including interviews with CAMHS directors and service managers. Results showed high evaluation activity and high quality, efficiency and efficacy of care compared with other services. Several restraints to the optimal application of the model were identified, including inadequate training of new managers, service overload, major external organisational change and limited investment in information systems. Other outcomes are discussed.
