National health insurance and the new health occupations: nurse practitioners and physicians' assistants

This article considers a number of issues which might arise in formulating policy for new health occupations. Its particular focus is on nurse practitioners and physicians' assistants and their treatment under potential national health insurance arrangements. The development and expansion of these occupations are described, as is the evidence on their performance with respect to the quality of medical care provided, the impact on the cost of such care, and changes in access to care. We then discuss several issues which might arise in the context of national health insurance legislation, including reimbursement rates and methods, certification and licensure, training subsidies, deployment incentives, and compatibility with an increased supply of physicians.     

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.     

PRACTICE ISSUES, STRATEGIES, AND MODELS

A recent Canadian study begins to address the lacuna in family mediation process research identified by Kelly. This study generated important data previously not available on a broad range of issues and concerns regarding the process and practice of family mediation and the extent of variability of current family mediation practice. The study focused on where family mediators position themselves in relation to salient issues and debates in the field; the interventions, methods, procedures, techniques, and strategies they find most useful and effective in their work; and the theories that guide them in their practice and the models of practice that they use. This article reports the key findings of the study and begins to discuss the implications of the research for mediation practice and sociolegal policy.     

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.
