Utility of Environmental Impact Assessment Processes in Western Australia: submission to inquiry into the environmental effects statement process in Victoria, Environment and Natural Resources Committee of the Parliament of Victoria

I have been asked to discuss a number of issues relating to the inquiry, including: •the key strengths of environmental impact assessment (EIA) processes in Western Australia (WA), including objectives, project referrals, levels of assessment, appeal rights for third parties, and the role of the Environment Protection Authority; •proposed reforms to the WA EIA Framework; •your experiences in environmental impact assessment processes in other jurisdictions, including examples of EIA best practice in Australia and overseas; •the role of strategic environmental assessment; •the most suitable body/agency to carry out EIA; and •post-EIA monitoring and enforcement. A brief report addressing these points is provided following an account of the EIA context in WA

Review of Environmental Impact Assessment in Australia: Theory and Practice by I Thomas and M Elliot

Repeat and first time visitation in an experience specific context: The Valley of the Giants Tree Top Walk.

Communication with the public is a primary consideration in the design of natural area tourist attractions (Manfredo & Bright,1991; Roggenbuck, 1992; Vogt & Stewart, 1998). In a management context, communication is essential in ensuring a relevant and enjoyable experience on the part of the visiting tourists (Magill, 1995). Communication also serves as an important management aid in reminding visitors of appropriate behaviour while ensuring continued visitor interest in the attraction (Moscardo, 1998; Moscardo & Woods,2001). This paper presents the results of a .survey examining motivations and attitudes of repeat and first time visitors to the Tree Top Walk site in the context of the communication strategy used at the site

Being subject-centred: A philosophy of teaching and implications for higher education

Being subject-centred as a higher education teacher offers a rich and illuminating philosophical and practical understanding of learning. Building upon previous research on subject-centred learning, we draw on reflection, literature review and a phenomenological approach to show how our ways of being infuse the teaching and learning environment. Philosophically, it is our way of being with our subject as teachers that influences the learning within our students. We show how posing the question: 'What is the best way to teach this subject?' helps a teacher find the best way to enhance the learning experience. It entails moving away from reliance solely on approaches that simply 're-present' content, such as lectures and online learning management systems, to interactive classrooms where space is created for the students to enter into their own engagement with the subject in a shared pursuit with the teacher, resulting in more effective teaching and learning. We illustrate this with personal accounts of our own journeys as teachers. We acknowledge that it takes courage to teach and to fully be subject-centred in the face of prevailing trends and pressures for other ways of teaching currently prominent in the higher education sector. But, ultimately, it is who we are as teachers that matters most, and being subject-centred provides the most effective way for us to most meaningfully reach our students

The IR stability of de Sitter: Loop corrections to scalar propagators

We compute 1-loop corrections to Lorentz-signature de Sitter-invariant 2-point functions defined by the interacting Euclidean vacuum for massive scalar quantum fields with cubic and quartic interactions. Our results apply to all masses for which the free Euclidean de Sitter vacuum is well-defined, including values in both the complimentary and the principal series of SO(D,1). In dimensions where the interactions are renormalizeable we provide absolutely convergent integral representations of the corrections. These representations suffice to analytically extract the leading behavior of the 2-point functions at large separations and may also be used for numerical computations. The interacting propagators decay at long distances at least as fast as one would naively expect, suggesting that such interacting de Sitter invariant vacuua are well-defined and are well-behaved in the IR. In fact, in some cases the interacting propagators decay faster than any free propagator with any value of $M^2> 0$.Comment: To appear in Phys. Rev.

Low defect, high purity crystalline layers grown by selective deposition

The purity and perfection of a semiconductor is improved by depositing a patterned mask of a material impervious to impurities of the semiconductor on a surface of a blank. When a layer of semiconductor is grown on the mask, the semiconductor will first grow from the surface portions exposed by the openings in the mask and will bridge the connecting portions of the mask to form a continuous layer having improved purity, since only the portions overlying the openings are exposed to defects and impurities

Comparison of six derivatizing agents for the determination of nine synthetic cathinones using gas chromatography-mass spectrometry

Six acylation reagents have been compared for their derivatisation potential towards nine synthetic cathinones by gas chromatography-mass spectrometry (GC-MS). The evaluated reagents were pentafluoropropionic anhydride (PFPA), trifluoroacetic anhydride (TFA), chlorodifluoroacetic anhydride (CLF2AA), heptafluorobutyric anhydride (HFBA), acetic anhydride (AA) and propionic anhydride (PA). The synthetic cathinones included flephedrone (4-fluoromethcathinone or 4-FMC), mephedrone (4-methylmethcathinone or 4-MMC), pentedrone (also known as α-methylamino-valerophenone), methedrone (4-methoxy-N-methcathinone, p-methoxymethcathinone), methylone (3,4-methylenedioxy-N-methylcathinone or bk-MDMA), butylone (β-keto-N-methylbenzodioxolylbutanamine or bk-MBDB), ethylone (3,4-methylenedioxy-N-ethylcathinone MDEC or bk-MDEA), pyrovalerone (4-methyl-β-keto-prolintane) and 3,4-methylenedioxypyrovalerone (MDPV). The derivatizing agents were optimised for incubation time and temperature with some important validation parameters studied to evaluate derivatisation reactions. The anhydrides studied proved to be suitable for synthetic cathinones – all of them showing RSD and accuracy below 20%. PFPA and HFBA followed by TFA are the best choice of derivatising agents based on validation parameters. Five internal standards were evaluated with good results. Three way ANOVA, interference, fragmentation patterns and high peak area values at a concentration of 0.50 μg ml−1 were evaluated and discussed. AA and PA derivatives give high relative abundance for most drugs examined. HFBA gives more ions and multi-fragmentation patterns
