Forensic applications of infrared chemical imaging: multi-layered paint chips

This paper examines the potential of infrared chemical (hyperspectral) imaging as a technique for the forensic analysis of automotive paint chips in particular, and multicomponent (e.g., layered) samples in general. Improved sample preparation procedures for the infrared analysis of paint chips are detailed, with the recommendation that where mounting resins are chemically incompatible with the sample, it is better to mount and section the sample in a soft wax from which the sections can be removed and pressed into a KBr disk for transmission analysis. Infrared chemical images of multilayered paint chips have been successfully obtained, with the chief advantage over conventional infrared analysis being that thousands of infrared spectra are collected in a few minutes across the whole sample, at a spatial resolution of around 5 microm. As with conventional infrared spectroscopy, chemical species can be identified from their spectra, but the wealth of information available can be also extracted in a number of different ways that make multicomponent spectral (and hence chemical) comparisons between two samples easy to visualize and understand. In one approach, the infrared chemical images of two paint chips being compared side-by-side can be viewed as a "movie," in which each frame is an intensity map of the two samples at a given wavenumber (frequency) value. In another approach, the spectra (pixels) in the image files are classified into chemically similar groups, resulting in a "cluster" image that makes it possible to simultaneously compare all of the layers in two paint chips. These methods are applicable to other multicomponent samples, and also to other chemical imaging techniques.     

Embedding SMEs in national systems of innovation: Participant perceptions of Australia's CRC-P program

Governments throughout the world employ a variety of policy mechanisms to promote economy-enhancing innovation, although the embedding of SMEs in national systems of innovation has generally proved problematic. The Australian Cooperative Research Centres – Projects Program represents a recent attempt to do precisely this. Interviews with participants in the first two rounds of the Program report high levels of satisfaction, but also highlight potential for friction between SMEs and research providers, together with the opportunity for strategic manipulation. This study provides government officials and other stakeholders with preliminary recommendations regarding where the Program is succeeding, and where further vigilance may be required.     

Collaborative research as an anti-poverty tool: a research partnership between police and indigenous Australians

This paper reports on a collaborative research project that shows how participatory social research can be used as a strategy for combating social exclusion. The Crime Prevention Partnership Project brought together dominant and disempowered groups to explore social issues of mutual concern and identify potential solutions. Indigenous Australian undergraduate students played a central role in this project, working with the police as customer service trainees and with the university as members of a project research group. This project became an opportunity to train and empower new researchers who, as people from disadvantaged groups, brought their own knowledge, concerns, and worldviews to a research process that they helped design and carry out themselves. The result was a learning process for all involved, referred to here as multi-directional empowerment. It led to tangible bridge building between mainstream, powerful institutions and a disadvantaged community. The project process offers a model for using participatory research as a framework in which to address development issues.     

Women's studies courses: Pragmatic and political issues concerning their establishment and design

When attempting to establish women's studies courses within institutions of higher education, women face a traditional power structure designed to obstruct movements for change. Four factors relevant to a power analysis of this situation are status, concrete resources, expertise and self-confidence. These factors are defined and examined in relation to the fight to establish women's studies courses. Within this background the issue of men as ‘patrons’ as teachers and as students, and the fact of women's anger are examined. Many arguments forwarded by conservative patriarchal institutions are discussed. The paper emerges from the experiences of the author in three universities. It is aimed at clarifying some of the traps set for women so that other women can eliminate any fears that their experiences are idiosyncratic or ‘their fault’ rather than part of a formalized power game.
