Studio enquiry and new frontiers of research

Given the growing complexity of human existence, there is a need for new ways of representing ideas and of illuminating the world and domains of knowledge. A growing recognition of the limits of traditional ways of representing the world has given rise to a search for alternative approaches to transform and represent the contents of consciousness or what can be known of lived experience. Researchers are recognising that scientific inquiry is just one type of research and that ‘research is not merely a species of social science’ (Eisner 1997: 261). Dissatisfaction with positivism and behaviourism as reductive modes of knowing has also come from within the science disciplines themselves. In his work entitled, The Discontinuous Universe, (1972) Werner Heisenberg states that the knowledge of science is applicable only to limited realms of experience and the scientific method is but a single method for understanding the world. Moreover, the notion of scientifically-based knowledge as statements of ultimate truth contains an inner contradiction since ‘the employment of this procedure changes and transforms its object’ (Heisenberg 1972: 189). The work of Heisenberg and others including: Lincoln and Denzin (2003), Schwandt, (2001) and Schon (1983) reveals that knowledge is relational and that different models of inquiry will yield different forms of knowledge.

Natural and environmentally responsive building envelopes

In a context of global warming and our needs to reduce CO\d2 emissions, building envelopes will play an important role. A new imperative has been put forth to architects and engineers to develop innovative materials, components and systems, in order to make building envelopes adaptive and responsive to variable and extreme climate conditions. Envelopes serve multiple functions, from shielding the interior environment to collecting, storing and generating energy. Perhaps a more recent concern of terrestrial habitats is permeability and leakages within the building envelope. Such airtight and concealed envelopes with zero particle exchange are a necessity and already exist in regard to space capsules and habitats.

This paper attempts to acknowledge existing and visionary envelope concepts and their functioning in conjunction with maintaining a favorable interior environment. It introduces several criteria and requirements of advanced fa\acades along with interior pressurization control. Furthermore, the paper also takes a closer look at the principles of "biomimicry" of natural systems combined with the most up-to-date building materials and construction technologies, trying to integrate the notions of adaptation - where the capacity to survive depends on the ability to adjust to the environment - within the concept of technological evolution and innovation. An "adaptive" attitude in the way in which we conceive our built structures provides a conceptual basis for the advanced building design of our future, as well as one concerned about the efficient management of the available resources. Built environments of the future (in extreme climates or not) will need to respond to Renewable, Adaptive, Recyclable and Environmental (R.A.R.E.) concepts in order to coexist in a sustainable way with their surroundings.

Playing a critical role: experiential learning resources and analytical media studies in higher education

This article compares two Information and Communication Technologies (ICTs) used in the Faculty of Arts, Deakin University Australia, and investigates the relationships between technology, pedagogy and key issues in the teaching and practice of public relations, in a media studies context. The online role-play ‘Save Wallaby Forest’ and the e-simulation ‘PRessure Point! Getting Framed (GF), in their different ways, afford learning  environments with capabilities that present public relations and media students with opportunities to discover a critical consciousness, break out of naturalised world-views, and explore alternative approaches to organisational communication. Furthermore, they present students with complex ethical issues to investigate based around the idea that media industries are powerful discursive producers and reproducers of social norms, values and beliefs which in turn shape notions of identity and influence the formation of public opinion in society (Fairclough 1999; Habermas 1995). This article explores the intersections and differences between these distinct ICTs in their relationships to a constructivist learning approach and ethical questions about how public relations both produces and reproduces world views through practice. This interacting nexus – between technology, pedagogy and theme – is significant because “what happens in the learning process” relates to the learning outcome and therefore has the potential to develop holistic reflexivity in studies of public relations (Laurillard 2003, p.42).

Lifecycle environmental impact and cost analyses of steel bridge piers with seismic risk

Lifecycle approaches have found their wide applications in analyzing, evaluating and assessing technologies and management methods in the infrastructure systems. While environmental problems such as global warming have become a serious issue in the world, researchers and practicing engineers in civil engineering have to pay attention to environmental impacts as well as function, safety, cost and aesthetics in the
whole lifecycle of civil infrastructures. In addition to the normal lifecycle activities accompanied with operation and aging, the effects of natural hazards such as earthquakes with a low occurrence probability but a high
hazard loss require a full consideration in determining both lifecycle cost and lifecycle environmental impact. In this research, an approach is proposed to predetermine the lifecycle environmental impact and costs of bridges from their construction and maintenance as well as the losses and recovery after natural hazards. Based on this research, it becomes possible to quantitatively outline the roles of bridge construction, maintenance and earthquake in both environmental impact and cost in the whole lifetime of a bridge, especially their constituent parts from seismic losses and recoveries.

lCT and educational (dis) advantage: families, computers and contemporary social and educational inequalities

Because access to new technologies is unequally distributed, there has been considerable debate about the growing gap between the so-called information-rich and information-poor. Such concerns have led to high-profile information technology policy initiatives in many countries. In Australia, in an attempt to 'redress the balance between the information rich and poor' by providing 'equal access to the World Wide Web' (Virtual Communities, 2002), the Australian Council of Trade Unions, Virtual Communities (a computer/software distributor) and Primus (an Internet provider) in late 1999 formed an alliance to offer relatively inexpensive computer and Internet access to union members in order to make 'technology affordable for all Australians' (Virtual Communities, 2002). In this paper, we examine four families, one of which had long-term Information and Communication Technologies (lCT) access, and three of which took advantage of the Virtual Communities offer to get home computer and Internet access for the first time. We examine their engagement with lCT and suggest that previously disadvantaged family members are not particularly advantaged by their access to lCT.

P(ICT)ures of English : teachers, learners and technology

The increasing challenges presented by information and communication technologies (ICTs) and the need for English curriculum to prepare young adults for the digital world are raised in this work. Viewed from the standpoint of current theoretical debates on the subject among educators, it draws on a wide range of classroom and real-world experiences to explore how technology affects the instruction of English. Teachers' knowledge of these technologies and their practices in assimilating them into English curriculums are celebrated and exciting scenarios for the future are presented.

A virtual environment for cultural and linguistic inclusivity teaching in a global environment

The Deakin University (Melbourne, Australia) operational policy on 'International and Culturally Inclusive Curricula' states that Deakin will incorporate international/intercultural perspectives and inclusive pedagogies into its courses in order to prepare all students to perform capably, ethically and sensitively in international, multicultural, professional and social contexts.

This paper is about a specific project to internationalise the teacher education curriculum through the use of Information and Communication Technologies (ICT). This project is scoped in the context of the UNESCO thrust of 'Education for All' in agreeing that inclusive societies begin with inclusive education practices. In our view current strategies have been insufficient to ensure that marginalized and excluded children receive access to their right to education.

The project aims to operationalise part of the UNESCO Dakar Framework for high quality learning environments by responding to ‘…the diverse needs and circumstances of learners and giving appropriate weight to the abilities, skills and knowledge they bring to the teaching and learning process’ by minimising language acquisition barriers that can otherwise impede effective communication and learning.

In addition, we need to be mindful of the marginalisation of people from non-English speaking backgrounds and therefore, in this initiative we use ICT to bridge the 'tyranny of distance' and offer a curriculum that values cultural and linguistic diversity.

In this paper we will discuss how we intend to develop these project principles. In particular we will indicate our plans to use relatively low cost, accessible software to develop a virtual environment where students can enter text in their native language, view foreign language text in their native language, hear text in their own language and automatically encode text into MP3 files and attach the files to messages.

Pedagogy of the flesh : artaud and pedagogical fault lines

In the form of an installation, this panel will question the problems of combining the fleshiness of our bodies and the technologies of (re-)presentation in the production of knowledge that is contemporary teaching in a material environment. Do the aesthetics and methods of the performing arts open up new, dynamic approaches towards teaching practices? Conversely, how do traditional approaches to classroom management and learning undermine the performativity of our disciplinary concerns? We wish to challenge in the strongest possible terms the appropriateness of the traditional format for academic conferences with their monologic presentation of research outcomes. We crave new and unimagined formats for conferences that rely upon the very theatrical devices that we study, master, enact, and live through. This installation will express each participant's response to these provocations and will provide an interactive environment with many dialogic elements. Participants will use video images, live performers, and other theatrical devices to create an installation that deconstructs the experience of teaching. Signalling though the flames, should our teaching be any less?

The installation will be available for perusal as five simultaneous events occur in over-lapping space. This will last approximately 45 minutes and will be followed by a round-table discussion for the remainder of our time.

The research and development of ChemGrid in CGSP

With the rapid development of computing technologies and network technologies, Grid technology has emerged as the solution for high-performance computing. Recently, the grid of orient-services has become a hot issue in this research area. In this paper, we propose an architecture of ChemGrid in CGSP (China Grid Support Platform). The effectiveness of the proposed architecture is demonstrated by an example which is developed as a Web service based on CGSP; the Web service is used for searching elements in the periodic table. An improvement of the user interface for applications is proposed in order to obtain results interactively. Finally, an extension of ChemGrid is discussed in order to integrate different types of resources and provide specialized services.

Examination of the role of intestinal Fatty acid-binding protein in drug absorption using a parallel artificial membrane permeability assay

Transcellular diffusion across the absorptive epithelial cells (enterocytes) of the small intestine is the main route of absorption for most orally administered drugs. The process by which lipophilic compounds transverse the aqueous environment of the cytoplasm, however, remains poorly defined. In the present study, we have identified a structurally diverse group of lipophilic drugs that display low micromolar binding affinities for a cytosolic lipid-binding protein—intestinal fatty acid-binding protein (I-FABP). Binding to I-FABP significantly enhanced the transport of lipophilic drug molecules across a model membrane, and the degree of transport enhancement was related to both drug lipophilicity and I-FABP binding affinity. These data suggest that intracellular lipid-binding proteins such as I-FABP may enhance the membrane transport of lipophilic xenobiotics and facilitate drug access to the enterocyte cytoplasm and cytoplasmic organelles.

Does an evidence-based sedation protocol improve practice and patient outcomes in critical care?

Learning Objective 1: compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients in an Australian critical care.

Learning Objective 2: explain the contrasting international research findings on sedation protocol implementation.
Minimization of sedation in critical care patients has recently received widespread support. Professional organizations internationally have published sedation management guidelines for critically ill patients to improve the use of research in practice, decrease practice variability and shorten mechanical ventilation duration. Innovations in practice have included the introduction of decision making protocols, daily sedation interruptions and new drugs and monitoring technologies. The aim of this study was to compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients in an Australian critical care setting.

A randomized, controlled trial design was used to study 312 mechanically ventilated adult patients in a general critical care unit at an Australian metropolitan teaching hospital. Patients were randomly assigned to receive protocol directed sedation management developed from evidence based guidelines (n=153) or usual clinical practice (n=159).

The median (95% CI) duration of ventilation was 58 hrs (44–78 hrs) for patients in the non-protocol group and 79 hrs (56–93) for those patients in the protocol group (p=0.20). Results were not significant for length of stay in critical care or hospital, the frequency of tracheostomies, and unplanned extubations. A Cox proportional hazards model estimated that protocol directed sedation management was associated with a 22% decrease (95% CI: 40% decrease to 2% increase, p=0.07) in the occurrence of successful weaning from mechanical ventilation.

Few randomized controlled trials have evaluated the effectiveness of protocol-directed sedation outside of North America. This study highlights the lack of transferability between different settings and different models of care. Qualified, high intensity nursing in the Australian critical care setting facilitates rapid, responsive decisions for sedation management and an increased success rate for weaning from mechanical ventilation.

The use of Web 2.0 Technologies to promote higher order thinking skills

During 2007 several independent Victorian secondary schools participated in a study exploring the ways in which the use of learning technologies can support the development of higher order thinking skills for students. This paper focuses on the use of Information and Communications Technologies (ICT) including Web 2.0 technologies for promoting effective teaching and learning in science. A case study methodology was used to describe how individual teachers used ICT and Web 2.0 in their settings. Data included interviews (focus group and individual), questionnaires, monitoring of teacher and student use of smart tools, analysis of curriculum documents and delivery methods and of student work samples. The evaluation used an interpretive methodology to investigate five research areas: Higher-order thinking, Metacognitive awareness, Team work/collaboration, Affect towards school/learning and Ownership of learning. Three cases are reported on in this paper. Each describes how student engagement and learning increased and how teachers’ attitudes and skills developed. Examples of student and teacher blogs are provided to illustrate how such technologies encourage students and teachers to look beyond text science.
