title: Vectorised SIMD Implementations of Morphology Algorithms

authors: Cree, Michael J.

abstract: We explore vectorised implementations, exploiting single instruction multiple data (SIMD) CPU instructions on commonly used architectures, of three efficient algorithms for morphological dilation and erosion. We discuss issues specific to SIMD implementation and describe how they guide algorithm choice. We compare our implementations to a commonly used opensource SIMD accelerated machine vision library and find orders of magnitude speed-ups can be achieved for erosions using two-dimensional structuring elements.

title: Dog Behaviour - Effect of Delay To Reinforcement

authors: Lord, Sarah

subjects: Reinforcement

abstract: Dogs were fed dry food as reinforcement and were required to touch a wand with their nose to get that reinforcement.  In the first study, half the dogs were given immediate reinforcement, while for the remaining dogs reinforcement was delayed by two seconds.  In the second study, dogs were food deprived for longer in an attempt to increase the food-motivation, and the position of the equipment was changed to increase the accuracy of detecting a correct response.  The third study was a replication of the second, but was conducted outdoors.  Number of reinforcers delivered and time between reinforcers was examined.  All three studies demonstrated that a two second delay to reinforcement slows learning in dogs, and in some cases prevents learning altogether.

title: "Kia Mauri Tau!" Narratives of recovery from disabling mental health problems

authors: Lapsley, Hilary

subjects: Maori

abstract: A bicultural research team at the University of Waikato successfully applied for funding from the Health Research Council to do a qualitative research project in the area of ‘pathways to wellness’. The Mental Health Narratives Project set out to gather forty narratives of mental ill health, recovery and life after recovery by interviewing Maori and non-Maori women and men who once had a disabling mental health problem. We aimed to describe journeys to mental health, identify key themes in accounts of the recovery process and describe the impact of the experience of mental ill health on life after recovery.
