Improving the reliability of child witness testimony in court : the importance of focusing on questioning techniques

Considerable discussion during recent years has focused on ways to increase the reliability of child witness evidence, and reduce the negative impact of the courtroom environment on children's credibility and their psychological well-being. A large proportion of this discussion has focused on removing child witnesses from the courtroom and developing alternative arrangements by which children can give evidence (e.g., videotaped statements used as evidence-in-chief, closed-circuit television). There is no doubt that these arrangements have played a major role in reducing children's feelings of uncertainty and intimidation, and they have increased the ability of children 10 tell their stories and answer questions reliably (Cashmore 2002; Eastwood & Patton 2002). However, there are many
other factors. apart from the physical environment in which a child's evidence is elicited, that impact on the quality and accuracy of a child witness's evidence.

This contemporary comment focuses on one of the most important factors that impacts on the quality and accuracy of a child's evidence; the questioning techniques. It offers four recommendations for improving the reliability of child witness evidence in court. along with justifications for these recommendations and suggestions for bow these recommendations might be implemented. Each suggestion focuses on the impact of questioning techniques, from pre-trial questioning to questioning during the trial. It does not focus on the rules of evidence regarding child statements or the physical environment in which children's evidence is elicited.

Focusing on university student engagement at the institutional level

In Australia, there has been a tendency to rely on quantitative indicators of university teaching quality. This has occurred partly because the indicators are perceived as objective and reliable and partly because they are relatively simple to gather and collate. A national project currently underway is based on the assumptions that teaching quality is multidimensional and that the identification and use of relevant indicators of teaching quality are dependent on the institutional environment. With a focus on student engagement, this paper outlines the research-based approach to developing indicators of teaching quality being taken by one Australian university participating in the national project.

Focusing in on structural genomics : the University of Queensland structural biology pipeline

The flood of new genomic sequence information together with technological innovations in protein structure determination have led to worldwide structural genomics (SG) initiatives. The goals of SG initiatives are to accelerate the process of protein structure determination, to fill in protein fold space and to provide information about the function of uncharacterized proteins. In the long-term, these outcomes are likely to impact on medical biotechnology and drug discovery, leading to a better understanding of disease as well as the development of new therapeutics. Here we describe the high throughput pipeline established at the University of Queensland in Australia. In this focused pipeline, the targets for structure determination are proteins that are expressed in mouse macrophage cells and that are inferred to have a role in innate immunity. The aim is to characterize the molecular structure and the biochemical and cellular function of these targets by using a parallel processing pipeline. The pipeline is designed to work with tens to hundreds of target gene products and comprises target selection, cloning, expression, purification, crystallization and structure determination. The structures from this pipeline will provide insights into the function of previously uncharacterized macrophage proteins and could lead to the validation of new drug targets for chronic obstructive pulmonary disease and arthritis.

Indigenous higher education student equity : focusing on what works

The rates of higher education access, participation and completion for Indigenous students are much lower than those for non-Indigenous students in Australia. This paper argues for a research-led focus on what works in terms of Indigenous  student equity in higher education. Undertaking independent evaluation of  existing initiatives and leveraging the experience of hundreds of successful Indigenous graduates, it may be possible to articulate some of the ways in which success has been, and can be, achieved, despite the challenges that face Indigenous students. In other words, it may be possible to articulate some aspects of what works for some Indigenous people in relation to higher education. A focus on articulating strategies that Indigenous individuals and communities might adopt in relation to higher education should be developed alongside the management of systemic problems through a range of means. The “successfocused” approach would provide one of a suite of approaches that may be helpful in addressing Indigenous student equity.

Focusing on solutions : the evaluation and development of individual university teachers

This paper outlines the rationale for a current research project that focuses on teaching development in individual university lecturers. The ways in which student evaluation of university teaching (SET) results are best used to bring about positive changes in teaching are discussed. It is argued that providing individualised evaluation feedback coupled with consultation to teachers is potentially valuable in terms of achieving positive and measurable impacts on teaching and learning at several levels within higher education systems.

Hydrodynamic flow focusing to study the isolated effects of the flow components

Biological fluids such as blood, proteins and DNA solutiosn moving within fluidic channels can potentially be exposed to high level of shear, extension or mixed stress, either in vitro such as industrial processing of blood products or in vivo such as ocurrs in some pathological conditions. This exposure to a high level of strain can trigger some reactions. In most of the cases the nature of the flow is mixed with shear and extensional components. The ability ot isolate the effects of each component is critical in order to understand the mechanisms behind the reactions and potentially prevent them. Applying hydrodynamic flow focusing, we present in this investigation the characterization of microchannels that allow study of the regions of high shear or high extension strain rate. Micro channels were fabricated in polydimethyl siloxane (PDMS)  using standard soft-lithography techniques with a photolithographically patterned mold. Characterization of the regions with high shear and high extension strain rate is presented. Computational Fluid Dynamics (CFD) simulations in three dimensions have been carried out to gain more detailed local flow information, and the results have been validated experimentally. A comparison between the numerical models and experiment and is presented. The advantages of microfluidic flow focusing in the study  of the effects of shear and extension strain rates for biological fluids are outlined.
