title: Matching productivity to resource availability in a small predator, the stoat (Mustela erminea)

authors: King, Carolyn M.

abstract: Stoats (Mustela erminea), introduced to New Zealand in the late nineteenth century, are common in New Zealand beech (Nothofagus sp.) forests, where populations of feral house mice (Mus musculus) fluctuate between years much as voles do in the northern hemisphere. We present new field evidence and two models demonstrating (i) a strong correlation between density indices for young stoats in summer and for mice in the previous spring, and (ii) a significant linear relationship between productivity per female and spring density of mice up to 25 mice captures per 100 trap-nights. These models confirm that short-lived small mustelid predators dependent on fluctuating populations of prey have evolved means of matching their productivity to the prospects of success across a wide range, from total failure in rodent crash years to >12 independent young per female in rodent peak years. We suggest that the enhanced reproductive success of female stoats when rodents are abundant is due to a combination of critical improvements in both the reproductive physiology and the foraging behaviour of female stoats in rodent peak years. Conversely, a drastic shortage of rodents increases the mortality of embryos and nestlings, while the adult females are able to survive, and even remain relatively fat, on other foods.

title: Freedom of association, freedom of contract, and the right-to-work debate

authors: Harcourt, Mark

subjects: freedom of association

abstract: The debate over union security arrangements is often presented as involving irreconcilable goals and values. Supporters of union security typically stress their importance to the union’s organizational strength and workers’ welfare. Right-to-work supporters, who favor banning such arrangements, typically emphasize employee freedom and choice. Our approach involves a unique comparison of both perspectives, which shows that neither perspective is completely compatible with safeguarding freedom. We therefore advocate reconciliation based on compulsory worker representation, which preserves the best freedom-enhancing properties of each perspective.

title: Dual cultural identity and tangihanga: Conflict, resolution and unexpected outcomes

authors: Edge, Kiri

subjects: bereavement

abstract: New Zealand has a significant number of dual-cultural whānau (families) which incorporate the identities of both Pākehā (New Zealander of European descent) and Māori (indigenous peoples of New Zealand). Little attention has been paid to the bereavement processes that will inevitably impact upon the lives of these whānau/families. As part of the Tangihanga Research Programme based at The University of Waikato, a directed study was conducted with a participant whose family/whānau included two life ways: Māori and Pākehā. An open-ended narrative approach was used to explore the participant’s bereavement after the death of his beloved wife. Two central themes emerged within the narrative, which related to conflict and eventual resolution. Decision-making processes and language played significant roles in the conflict experienced by the participant. Communication and compromise helped to resolve these conflicts. Unexpected outcomes included new understandings and strengthened connections between the participant and his wife’s marae.
