title: English and the NCEA: the impact of an assessment regime on curriculum and practice.

authors: Locke, Terry

subjects: curricula (courses of study)

abstract: The National Certificate of Educational Achievement (NCEA) will enter the first year of implementation for Year 11 students in 2002. A number of educators have raised concerns in relation to the NCEA in respect of such issues as validity, reliability, moderation, the lack of uniformity in respect of re-testing policy and manageability. This article argues that attention also needs to be directed at ways in which the NCEA constructs curriculum, assessment and pedagogical practice. Using English as an example, it does just that by examining the English matrix, a specific achievement standard and examples of assessment tasks. It argues that the pervasiveness of summative assessment and the provision of centrally designed materials will legitimise some versions of the subject and certain teaching practices over others. It suggests that this form of legitimating control undermines teacher professionalism and subject innovation.

title: Observations on adaptive vector filters for noise reduction in color images

authors: Cree, Michael J.

subjects: adaptive filters

abstract: In a series of papers, Plataniotis et al. proposed a number of filters for noise reduction in color images where the noise type is unknown. In this letter, those filters with a unified notation are summarized, and it is shown that they are essentially variants of the same filtering procedure. It is also shown that the class of adaptive vector filters can be considered as interpolants between the arithmetic mean filter and the vector median filter. Results are presented of numerical computations with the filters on test images corrupted with noise. It is found that the adaptive vector filters perform well with general applicability.

title: Kuta (Eleocharis sphacelata, Cyperaceae), a locally important and highly valued weaving plant

authors: Wehi, Priscilla M.

subjects: Northland (N.Z.)

abstract: This article introduces and discusses kuta (Eleocharis sphacelata, Cyperaceae), a tall spikerush found on the margins of shallow lakes in New Zealand, which, although often overlooked, is considered in Northland to be a valuable weaving resource.
