Proportion estimation using prior cluster purities
The prior distribution of CLASSY component purities is studied, and this information incorporated into maximum likelihood crop proportion estimators. The method is tested on Transition Year spring small grain segments
An algorithm for the rapid location of an extreme of a function subject only to geometric restrictions
The requirements of symmetry and convexity in the application of algorithms for the minimization or maximization of a function are discussed. It is argued that if a function of a single variable is convex and symmetric in a neighborhood of an extremum, the extremum may be approximated to the precision that increases by at least a power of two per functional evaluation. The procedure may be used to drive a complex optimization procedure in the multivariate area estimation problem encountered in remote sensing

The sustainable delivery of sexual violence prevention education in schools
Sexual violence is a crime that cannot be ignored: it causes our communities significant
consequences including heavy economic costs, and evidence of its effects can be seen in our
criminal justice system, public health system, Accident Compensation Corporation (ACC),
and education system, particularly in our schools. Many agencies throughout New Zealand
work to end sexual violence. Auckland-based Rape Prevention Education: Whakatu Mauri
(RPE) is one such agency, and is committed to preventing sexual violence by providing a
range of programmes and initiatives, information, education, and advocacy to a broad range
of audiences.
Up until early 2014 RPE employed one or two full-time positions dedicated to co-ordinating
and training a large pool (up to 15) of educators on casual contracts to deliver their main
school-based programmes, BodySafe – approximately 450 modules per year, delivered to
some 20 high schools. Each year several of the contract educators, many of whom were
tertiary students, found secure full time employment elsewhere. To retain sufficient
contract educators to deliver its BodySafe contract meant that RPE had to recruit, induct
and train new educators two to three times every year. This model was expensive, resource
intense, and ultimately untenable. The Executive Director and core staff at RPE wanted to
develop a more efficient and stable model of delivery that fitted its scarce resources.
To enable RPE to know what the most efficient model was nationally and internationally,
with Ministry of Justice funding, RPE commissioned Massey University to undertake this
report reviewing national and international research on sexual violence prevention
education (SVPE). [Background from Executive Summary.]Rape Prevention Education: Whakatu Maur

A bound for the smoothing parameter in certain well-known nonparametric density estimators
Two classes of nonparametric density estimators, the histogram and the kernel estimator, both require a choice of smoothing parameter, or 'window width'. The optimum choice of this parameter is in general very difficult. An upper bound to the choices that depends only on the standard deviation of the distribution is described

Minimum variance geographic sampling
Resource inventories require samples with geographical scatter, sometimes not as widely spaced as would be hoped. A simple model of correlation over distances is used to create a minimum variance unbiased estimate population means. The fitting procedure is illustrated from data used to estimate Missouri corn acreage
