title: Image intensifier characterization

authors: Payne, Andrew D.

subjects: image intensifier

abstract: An image intensifier forms an integral part of a full-field image range finder under development at the University of Waikato. Operating as a high speed shutter with repetition rates up to 100 MHz, a method is described to characterise the response, both temporally and spatially, of the intensifier in order to correct for variations in the field of view and to optimise the operating conditions. A short pulse of visible light is emitted by a laser diode, uniformly illuminating the image intensifier, while a CCD camera captures the output from the intensifier. The phase of the laser pulse is continuously varied using a heterodyne configuration, automatically producing a set of samples covering the modulation cycle. The results show some anomalies in the response of our system and some simple solutions are proposed to correct for these.

title: New Zealand women’s employment patterns: Diversity or homogeneity?

authors: Hillcoat-Nallétamby, Sarah

abstract: New Zealand has experienced sustained increases in women’s labour force participation since the post-war period. When observed across time, work patterns provide insights to the changing overall lifetime attachment of women to the labour market. Using data from the 1995 sample survey New Zealand Women: Family, Employment, Education, we present descriptive findings on the work patterns of women born between 1936 and 1965, and depict these patterns in terms of spells in and out of work. A cohort perspective is taken. We then proceed to summarise the details of these individual work histories using summary measures which can then be correlated with potential explanatory factors. The results show that by the age of 30, successive birth cohorts have experienced: (i) increasing complexities in their work and non-work trajectories; (ii) childbearing continues to depress women’s engagement in paid work across time; and (iii) the influence of educational attainment and ethnicity seems to be changing.

title: Te Kotahitanga: culturally responsive professional development for teachers

authors: Bishop, Russell

subjects: indigenous

abstract: Te Kotahitanga is a research and professional development project that aims to support teachers to raise the achievement of New Zealand's indigenous Māori students in public/mainstream classrooms. An Effective Teaching Profile, developed from the voices of Māori students, their families, principals and some of their teachers, provides direction and focus for both the classroom pedagogy and the professional development. While the authors understand that there are many institutional changes necessary at the school level, this paper focuses on the professional learning opportunities developed for classroom teachers within this project to support the development of more effective classroom relationships and interactions with Māori students. This has resulted in Māori students attending school more regularly, engaging as learners and achieving to levels where they begin to realise their true potential.
