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

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

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

The IR stability of de Sitter QFT: Physical initial conditions

This work uses Lorentz-signature in-in perturbation theory to analyze the late-time behavior of correlators in time-dependent interacting massive scalar field theory in de Sitter space. We study a scenario recently considered by Krotov and Polyakov in which the coupling $g$ turns on smoothly at finite time, starting from $g=0$ in the far past where the state is taken to be the (free) Bunch-Davies vacuum. Our main result is that the resulting correlators (which we compute at the one-loop level) approach those of the interacting Hartle-Hawking state at late times. We argue that similar results should hold for other physically-motivated choices of initial conditions. This behavior is to be expected from recent quantum "no hair" theorems for interacting massive scalar field theory in de Sitter space which established similar results to all orders in perturbation theory for a dense set of states in the Hilbert space. Our current work i) indicates that physically motivated initial conditions lie in this dense set, ii) provides a Lorentz-signature counter-part to the Euclidean techniques used to prove such theorems, and iii) provides an explicit example of the relevant renormalization techniques.Comment: 32 pages, 3 figure

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.
