Carbon taxation governance is becoming increasingly popular, further evolving the polluter pays concept already well established in the built environment as a mechanism to controlling and licensing waste generation. This paper presents an explanation of property asset ‘regeneration reuse’ principles following deconstruction, which reduce waste generation associated with the process of demolition, construction and operation. An analysis is made of strategies in Australia and the United Kingdom, comparing jurisdiction targets pertaining to construction and demolition waste that encourage ‘regeneration reuse’. From examination of applicable Australian and United Kingdom legislation, strategic, fiscal and policy that influence on the 'regeneration reuse' of property assets, an evaluation to the variety of issues relevant to waste and resource management practices is reached. The paper concludes that a systematic evaluation framework to selecting building components and structures suitable for reuse after deconstruction must be considered in legislation.

The session examines the role of the metaphysical and physical in art and animation and how this relates to natural spaces. Soviet Russian film director and theorist Sergei Eisenstein saw animation as possessing an ability called “plasmaticity”, the capacity for a being to assume any conceivable form dynamically. He saw each being as “primordial protoplasm, not yet possessing a ‘stable’ form, but capable of assuming any form” (Eisenstein 1989, 21). He was enamoured by the capacity of animation to transform and be liberated, of being able to escape from a fixed and static identity—to embody a "rejection of the once-­‐and-­‐forever allotted form" in which we are held (Eisenstein 1989, 21). Czech Surrealist animator Jan Švankmajer uses a metaphysical approach based on a belief in animism to art and animation. He believes that objects possess a conscious life or spirit, he says ‘Objects conceal within themselves the events they’ve witnessed. I don’t actually animate objects. I coerce their inner life out of them.’ (Švankmajer in Imre 2009, 214) In this animistic world there are no boundaries or rules, no physical or conceptual restrictions; anything is possible, with inanimate objects and places able to become animate and transact in a conscious relationship with humans and each other. This session invites artists, animators and theorists to discuss their conceptions and approaches to using visuals to promote and provoke transformation.

O Instituto Brasileiro de Meio Ambiente (IBAMA), executor da Política Nacional de Meio Ambiente tem sido objeto de constante avaliação por diferentes segmentos da sociedade brasileira. Este estudo visa subsidiar a construção de perspectivas analíticas sobre a efetividade de suas ações, a partir de uma análise sobre a composição de sua cultura organizacional. A hipótese foi formulada no sentido de que a existência de concepções diferenciadas para o termo meio ambiente entre os trabalhadores do Instituto possui relação com o processo de constituição da cultura organizacional do IBAMA. Essa perspectiva se deu pela vivência da pesquisadora no campo ambiental, em especial, por ter pertencido ao mesmo corpo funcional do Instituto. Essa mesma condição possibilitou acrescer na historiografia do IBAMA aspectos referentes à influência da conceituação teórica para o termo ambiente na cultura organizacional do Instituto. A pesquisa foi orientada pelos fundamentos teóricos de autores que investigam a cultura, o poder e o comportamento de organizações, como TAVARES (1991), SCHERMERHORN, HUNT & OSBORNO (2001), FLEURY ( 2009) e, BERTERO (2009). Adotou como estratégias metodológicas as técnicas de observação, de questionários e de entrevistas seguindo as orientações de GOODE E HATT (1973), GIL (1994) e LAKATOS (2003) para a identificação das relações entre conceituação de ambiente por parte de trabalhadores do IBAMA. Na perspectiva do conceito de seres históricos de CASTORIADIS (1982) foram analisados registros de falas de outros atores sociais que escreveram a história da gestão ambiental pública brasileira. A tese apresenta a coexistência de duas conceituações ativas para o termo meio ambiente derivadas do processo de ambientalização do IBAMA.

Chemical and biological processes, such as dissolution in gypsiferous sands and biodegradation in waste refuse, result in mass or particle loss, which in turn lead to changes in solid and void phase volumes and grading. Data on phase volume and grading changes have been obtained from oedometric dissolution tests on sand–salt mixtures. Phase volume changes are defined by a (dissolution-induced) void volume change parameter (Λ). Grading changes are interpreted using grading entropy coordinates, which allow a grading curve to be depicted as a single data point and changes in grading as a vector quantity rather than a family of distribution curves. By combining Λ contours with pre- to post-dissolution grading entropy coordinate paths, an innovative interpretation of the volumetric consequences of particle loss is obtained. Paths associated with small soluble particles, the loss of which triggers relatively little settlement but large increase in void ratio, track parallel to the Λ contours. Paths associated with the loss of larger particles, which can destabilise the sand skeleton, tend to track across the Λ contours.

En este trabajo establecemos la siguiente hipótesis: el sistema conjeturas-pruebas-refutaciones constituye la lógica del descubrimiento matemático escolar; bien entendido que en las matemáticas de la enseñanza secundaria el énfasis no puede situarse en la frontera móvil que Lakatos (1978) ha señalado en el trabajo de los matemáticos profesionales, esto es, la frontera demostraciones/refutaciones sino más bien en la frontera anterior, conjeturas/demostraciones. Dicho sistema supera didácticamente al enfoque unidimensional de demostración como prueba formalizada, enfoque tradicional del estilo deductivista en la enseñanza de las matemáticas. Esta hipótesis surge del análisis de las dificultades epistemológicas, cognitivas y didácticas del concepto de demostración (en particular, de la demostración por reducción al absurdo) y de la revisión de algunos estudios experimentales sobre la práctica escolar de la demostración.

We present an analysis of comet activity based on the Spitzer Space Telescope component of the Survey of the Ensemble Physical Properties of Cometary Nuclei. We show that the survey is well suited to measuring the activity of Jupiter-family comets at 3-7 AU from the Sun. Dust was detected in 33 of 89 targets (37 ± 6%), and we conclude that 21 comets (24 ± 5%) have morphologies that suggest ongoing or recent cometary activity. Our dust detections are sensitivity limited, therefore our measured activity rate is necessarily a lower limit. All comets with small perihelion distances (q <1.8 AU) are inactive in our survey, and the active comets in our sample are strongly biased to post-perihelion epochs. We introduce the quantity ɛfρ, intended to be a thermal emission counterpart to the often reported Afρ, and find that the comets with large perihelion distances likely have greater dust production rates than other comets in our survey at 3-7 AU from the Sun, indicating a bias in the discovered Jupiter-family comet population. By examining the orbital history of our survey sample, we suggest that comets perturbed to smaller perihelion distances in the past 150 yr are more likely to be active, but more study on this effect is needed.

Recent evidence indicates that dogs' sociocognitive abilities and behaviour in a test situation are shaped by both genetic factors and life experiences. We used the 'unsolvable task' paradigm to investigate the effect of breed and age/experience on the use of human-directed gazing behaviour. Following a genetic classification based on recent genome analyses, dogs were allocated to three breed groups, namely Primitive, Hunting/Herding and Molossoid. Furthermore, we tested dogs at 2 months, 4.5. months and as adults. The test consisted of three solvable trials in which dogs could obtain food by manipulating a plastic container followed by an unsolvable trial in which obtaining the food became impossible. The dogs' behaviour towards the apparatus and the people present was analysed. At 2 months no breed group differences emerged and although human-directed gazing behaviour was observed in approximately half of the pups, it occurred for brief periods, suggesting that the aptitude to use human-directed gazing as a request for obtaining help probably develops at a later date when dogs have had more experience with human communication. Breed group differences, however, did emerge strongly in adult dogs and, although less pronounced, also in 4.5-month-old subjects, with dogs in the Hunting/Herding group showing significantly more human-directed gazing behaviour than dogs in the other two breed groups. These results suggest that, although the domestication process may have shaped the dog's human-directed communicative abilities, the later selection for specific types of work might also have had a significant impact on their emergence. © 2011 The Association for the Study of Animal Behaviour.
