3D virtual geology field trips: opportunities and limitations
As a part of The OpenScience Laboratory, (http://www.open.ac.uk/blogs/openscience/), an initiative of The Open University (OU) and The Wolfson Foundation, we are developing a 3D simulation of a Geology field trip based around Skiddaw in the Lake District, using the Unity 3D software (http://unity3d.com/). We are using digital data and imagery to reconstruct the landscape faithfully enough to provide a real sense of presence for the user.
The application will be based around a 10km x 10km low/medium detail model of the terrain and LiDAR data around Skiddaw, with overlaid aerial photography, and including walls, trees, buildings etc.
The Skiddaw field trip in the Lake District is an integral part of Earth science teaching at the OU; students carry out a real field trip and can also learn about it through DVD activities. The primary objective of developing an authentic 3D interactive simulation has been to provide an immersive experience to the users through sense of space. The virtual embodiment in the form of avatars and the multi-user environment will help give a sense of co-presence and provide opportunities for collaborative learning. The interactions and the learning activities within the 3D environment are designed to mirror the experience of a real field trip.
We aim to have an operational 3D virtual geology trip by the time of the Conference in April 2013. During the workshop and through demonstration of the 3D field trip, we plan to address: comparison of the 3D experience with 2D virtual field trips; the role that a 3D virtual geology field trip can play in terms of preparation and reflection before and after a real field trip; and whether and how a 3D simulation helps in gaining geological fieldwork skills and what are the limitations of 3D virtual geology field trips

Pedagogical advantages of 3D virtual field trips and the challenges for their adoption
In a six-month long Innovate UK-funded project (November 2015 – April 2016), we investigated the feasibility of creating a sustainable national 3D ‘virtual field-trips’ (VFT) software service, to support and deliver field trip-based education through a virtual channel in schools and higher education institutions (HEIs). The idea of a 3D VFT service emerged from Virtual Skiddaw App, the 3D virtual geology fieldtrip, of The Open University’s (OU) Open Science Laboratory . In the feasibility project, we (at the OU) (co-investigator) along with Daden (project-lead) and Design Thinkers, UK (co-investigator) we looked into the technical, pedagogical, commercial and service design aspects of the 3D VFT service.
In this presentation, we focussed on the pedagogy strand of this feasibility project: pedagogical advantages of 3D VFTs, and the challenges for their adoption in schools and HEIs.
We discussed the following:
pedagogical underpinnings of 3D virtual environments and 3D VFTs in disciplines such as geology, biology, environmental science/studies and geography which are founded on field observations, exploration and enquiry;
potential of integrating VFTs within the curricula in schools and in HEIs;
perceptions of educators, students and assessment bodies towards 3D VFTs, and virtual fieldwork, in general; we used the Virtual Skiddaw App in workshops and presentations to illustrate the concept of a 3D VFT;
views of stakeholders towards the 3D VFT service: advantages, challenges and their requirements from this service.
Our empirical investigations have been user-centred – focussing on the stakeholders and particularly, the end-users such as educators, students and fieldwork specialists, and we have interacted with them via interviews, service design workshops, demonstrations and a survey to elicit their perceptions and requirements
Tax Evasion, Tax Avoidance and Tax Planning in Australia: The participation in mass-marketed tax avoidance schemes in the Pilbara region of Western Australia in the 1990s
This paper will examine the development of mass-marketed tax avoidance schemes in Australia. It will consider changes in approach to tax avoidance from the ‘bottom of the harbour’ schemes of the 1960s and 1970s to the mass-marketed tax avoidance schemes of the 1990s. It will examine the changing structure of tax avoidance from individually crafted tax avoidance structures designed by accountants and lawyers used by high wealth individuals to mass produced structures targeted at highly paid, and therefore highly taxed, blue collar workers in Australia’s mining industry in the 1990s.
In the latter half of the twentieth century ‘unacceptable’ tax planning went from highly expensive, individually ‘tailor made’ structures afforded and used only by the very wealthy, to inexpensive replicated structures marketed to skilled and unskilled tradespeople and labourers. By 1998 over 42 000 Australian taxpayers were engaged in tax avoidance schemes with the highest proportion focussed in the mining regions of Western Australia. In the remote and inhospitable mining community of Pannawonica, which has one of the highest paid workforces in Australia, the Australian Taxation Office identified that as many as one in five taxpayers were engaged in a mass-marketed tax avoidance scheme.
The paper will identify the causes of these changes, including the advent of the computerised information technology which permitted ‘mass production’ of business structures designed to exploit business incentives in the Australian taxation system in the 1990s. It will also set these developments within the broader context of the tax compliance culture prevailing in Australia and overseas during this period
Exploring the dynamics of compliance with community penalties
In this paper, we examine how compliance with community penalties has been theorized hitherto and seek to develop a new dynamic model of compliance with community penalties. This new model is developed by exploring some of the interfaces between existing criminological and socio-legal work on compliance. The first part of the paper examines the possible definitions and dimensions of compliance with community supervision. Secondly, we examine existing work on explanations of compliance with community penalties, supplementing this by drawing on recent socio-legal scholarship on private individuals’ compliance with tax regimes. In the third part of the paper, we propose a dynamic model of compliance, based on the integration of these two related analyses. Finally, we consider some of the implications of our model for policy and practice
concerning community penalties, suggesting the need to move
beyond approaches which, we argue, suffer from compliance myopia; that is, a short-sighted and narrowly focused view of the issues
Postglacial fringing-reef to barrier-reef conversion on Tahiti links Darwin's reef types.
In 1842 Charles Darwin claimed that vertical growth on a subsiding foundation caused fringing reefs to transform into barrier reefs then atolls. Yet historically no transition between reef types has been discovered and they are widely considered to develop independently from antecedent foundations during glacio-eustatic sea-level rise. Here we reconstruct reef development from cores recovered by IODP Expedition 310 to Tahiti, and show that a fringing reef retreated upslope during postglacial sea-level rise and transformed into a barrier reef when it encountered a Pleistocene reef-flat platform. The reef became stranded on the platform edge, creating a lagoon that isolated it from coastal sediment and facilitated a switch to a faster-growing coral assemblage dominated by acroporids. The switch increased the reef's accretion rate, allowing it to keep pace with rising sea level, and transform into a barrier reef. This retreat mechanism not only links Darwin's reef types, but explains the re-occupation of reefs during Pleistocene glacio-eustacy

A national-scale assessment of climate change impacts on species: assessing the balance of risks and opportunities for multiple taxa
It is important for conservationists to be able to assess the risks that climate change poses to species, in order to inform decision making. Using standardised and repeatable methods, we present a national-scale assessment of the risks of range loss and opportunities for range expansion, that climate change could pose for over 3,000 plants and animals that occur in England. A basic risk assessment that compared projected future changes in potential range with recently observed changes classified 21% of species as being at high risk and 6% at medium risk of range loss under a B1 climate change scenario. A greater number of species were classified as having a medium (16%) or high (38%) opportunity to potentially expand their distribution. A more comprehensive assessment, incorporating additional ecological information, including potentially confounding and exacerbating factors, was applied to 402 species, of which 35 % were at risk of range loss and 42 % may expand their range extent. This study covers a temperate region with a significant proportion of species at their poleward range limit. The balance of risks and opportunities from climate change may be different elsewhere. The outcome of both risk assessments varied between taxonomic groups, with bryophytes and vascular plants containing the greatest proportion of species at risk from climate change. Upland habitats contained more species at risk than other habitats. Whilst the overall pattern was clear, confidence was generally low for individual assessments, with the exception of well-studied taxa such as birds. In response to climate change, nature conservation needs to plan for changing species distributions and increasing uncertainty of the future
