title: Conceptual review article

authors: O’Driscoll, Michael P.

subjects: stress

abstract: The article which follows is the second in our series of ‘conceptual’ reviews, which provide a forum for leading researchers of stress and well-being to present an overview and critique of a specifi ed area of stressrelated research. The overarching goals of this section of the journal are to (a) review extant theories and research on stress and health, (b) offer an opportunity for new conceptual frameworks to be articulated and critiqued and (c) develop and promote theoretical frameworks associated with stress, health, coping and well-being.

title: Video-rate or high-precision: A flexible range imaging camera

authors: Dorrington, Adrian A.

subjects: range image

abstract: A range imaging camera produces an output similar to a digital photograph, but every pixel in the image contains distance information as well as intensity. This is useful for measuring the shape, size and location of objects in a scene, hence is well suited to certain machine vision applications.
Previously we demonstrated a heterodyne range imaging system operating in a relatively high resolution (512-by-512) pixels and high precision (0.4 mm best case) configuration, but with a slow measurement rate (one every 10 s). Although this high precision range imaging is useful for some applications, the low acquisition speed is limiting in many situations. The system’s frame rate and length of acquisition is fully configurable in software, which means the measurement rate can be increased by compromising precision and image resolution. 
In this paper we demonstrate the flexibility of our range imaging system by showing examples of high precision ranging at slow acquisition speeds and video-rate ranging with reduced ranging precision and image resolution. We also show that the heterodyne approach and the use of more than four samples per beat cycle provides better linearity than the traditional homodyne quadrature detection approach. Finally, we comment on practical issues of frame rate and beat signal frequency selection.

title: An evaluation of Te Rau Puawai workforce 100: Perspectives of Te Rau Puawai bursars

authors: Nikora, Linda Waimarie

subjects: Maori students

abstract: The Te Rau Puawai programme is an attempt to change the nature of the Maori
mental health workforce. To do this, Maori with aspirations to work, or to continue to
work in the mental health workforce, are supported, financially and academically, to
complete a tertiary qualification relevant to the field.
To evaluate the Te Rau Puawai programme, the Ministry of Health commissioned the
Maori and Psychology Research Unit of the University of Waikato in July 2001. The
overall aim of the evaluation was to provide the Ministry with a clearer understanding
of the programme including: the perceived critical success factors, the barriers if any
regarding Te Rau Puawai, the impact of the programme, the extent to which the
programme may be transferable, gaps in the programme, and suggested
improvements.
The evaluation team set out to gather the experiences and perspectives of recipients of
Te Rau Puawai services by asking all bursars to complete a questionnaire and
volunteer for follow up interviews or focus groups. Sixty two bursars responded to
our questionnaire, and we complete focus group or individual follow up interviews
with 19 bursars.
