title: Chronology of fans and terraces in the Galatea Basin

authors: Pain, C.F.

abstract: Air-borne volcanic ash beds are used to date fans and terraces in the Galatea Basin and to outline the depositional history of this part of the Rangitaiki Valley. The basin is interpreted as a fault-angle depression formed by a downwarped sheet of ignimbrite and an upthrusted block of greywacke which forms the Ikawhenua Range. It is from this range that much of the detritus has been derived to fill the basin, deposited mainly in the form of fans and terraces. The larger fans cover a wide area and their surfaces are older than the Rotoma eruption of c. 8000 years B.P. The widespread occurrence of these fans indicates a major erosion interval between c. 11,000 and c. 8,000 years ago. The younger fans are distributed in a particular order with fans of the Pre-Taupo surface north of the Horomanga Stream and those of the Pre- and Post-Kaharoa surfaces south of the same stream. This ordered distribution of the younger fans suggests a climatic control of fan building.

Aggradation and degradation phases in the Rangitaiki and Whirinaki Rivers have formed a pronounced meander trough containing terraces of the Pre-Taupo, Pre-Kaharoa, and Post-Kaharoa surfaces. The terrace of the Pre-Kaharoa surface, largely of Taupo Pumice alluvium, is the most common. Degradation, however, is controlled by a local base level at the ignimbrite rapids on the Rangitaiki River just north of the Galatea Basin.

title: Can redirected aggression explain interspecific attacks by Australian magpies on other birds?

authors: Morgan, Dai K.J.

subjects: agonistic behaviour

abstract: Attacks by participants of conflicts against a third party are referred to as redirected aggression. Usually the third party is a conspecific — few documented cases of redirected aggression against other species exist. The Australian magpie (Gymnorhina tibicen), however, often attacks other species; the reasons for attacks are largely unknown. Some attacks occur after territorial disputes with conspecifics, suggesting that attacks are the result of redirected aggression. We subjected eight Australian magpie groups to simulated territorial intrusions. In one treatment an Australian magpie and rock dove (Columba livia) were presented in cages next to one another (5 m apart) on the territory for 30 min; the Australian magpie decoy was then covered and aggressive responses toward the rock dove by residents were recorded for a further 30 min (Treatment 1). Two additional treatments were presented in an identical manner on each territory where both decoys were either Australian magpies (Treatment 2) or rock doves (Treatment 3). We predicted that if Australian magpies regularly redirect aggression onto benign species after conspecific territorial intrusions, attack rates on the rock dove decoy in Treatment 1 would be higher than attack rates on the rock dove decoy in Treatment 3. Residents were seldom recorded close (<1 m) and not seen attacking rock dove decoys during tests. In contrast, Australian magpie decoys were often approached and attacked by residents. After a decoy was covered (following the first 30 min phase), residents spent little time in close proximity (on cage, <0.3 m, or 0.3-1 m) to the rock dove decoy in either Treatment 1 or Treatment 3; in contrast, residents were often recorded close to the Australian magpie decoy in Treatment 2. We found no evidence that Australian magpies redirect aggression onto other birds after territorial intrusions. The true proportion of territorial disputes leading to redirected attacks may be small, or only occur under highly specific contexts.

title: An Evaluation of an Impaired Driver Treatment Programme Facilitated by Tūhoe Hauora

authors: Waru, Nicole Arihia

subjects: Tuhoe Hauora

abstract: Driving while impaired is a substantial issue in Aotearoa.  It has the potential to result in loss of life and cause significant health and economic strain on society.  Recidivist impaired drivers are major contributors to this problem.  Countermeasures of impaired driving have previously included liquor licencing, drinking age restrictions, health promotion campaigns and health rehabilitation therapies.  The Ministry of Health offer an Impaired Driving therapy throughout Aotearoa as countermeasure to this issue.  The programme is administered through the funder-contract system. Participation is compulsory for those mandated by court order.  
This study evaluates an Impaired Driver programme facilitated by Tūhoe Hauora; a kaupapa Māori mental health and addiction provider based in Taneatua, Eastern Bay of Plenty.  The course is delivered once weekly over a period of ten weeks to a group of twelve or less recidivist impaired drivers or first time offenders who were convicted of driving with excessive levels of breath alcohol.    
The evaluation draws from a community psychology paradigm in exploration of the lived experiences of programme participants, in the context of course 2 of the 2014 Tūhoe Hauora Impaired Driving course.  
The experiences of five individuals were explored using in-depth face to face interviews and presented using a case-by-case approach.  Participant observation, document review, evaluation visits and participant surveys were used as supplement methods of inquiry.  The findings illustrated that Tūhoe Hauora met contract requirements by addressing impaired driving recidivism to date of interview.  The evaluation also found the course actualising the mission of Tūhoe Hauora which was to address the holistic well-being of programme participants.  The research did present areas in the programme that could be improved particularly pertaining to the referral process and a need for agency collaboration.  Recommendations were formulated in attempt to address the programme gaps and discussion is offered in addressing the multi-layered oppression that was experienced throughout the evaluation process by both Tūhoe Hauora and the evaluation participants.
