title: Late Miocene to early Pliocene biofacies of Wanganui and Taranaki Basins, New Zealand: Applications to paleoenvironmental and sequence stratigraphic analysis

authors: Hendy, Austin J.W.

subjects: Wanganui Basin

abstract: The Matemateaonga Formation is late Miocene to early Pliocene (upper Tongaporutuan to lower Opoitian New Zealand Stages) in age. The formation comprises chiefly shellbeds, siliciclastic sandstone, and siltstone units and to a lesser extent non-marine and shallow marine conglomerate and rare paralic facies. The Matemateaonga Formation accumulated chiefly in shelf paleoenvironments during basement onlap and progradation of a late Miocene to early Pliocene continental margin wedge in the Wanganui and Taranaki Basins. The formation is strongly cyclothemic, being characterised by recurrent vertically stacked facies successions, bounded by sequence boundaries. These facies accumulated in a range of shoreface to mid-outer shelf paleoenvironments during conditions of successively oscillating sea level. This sequential repetition of facies and the biofacies they enclose are the result of sixth-order glacio-eustatic cyclicity. Macrofaunal associations have been identified from statistical analysis of macrofossil occurrences collected from multiple sequences. Each association is restricted to particular lithofacies and stratal positions and shows a consistent order and/or position within the sequences. This pattern of temporal paleoecologic change appears to be the result of lateral, facies-related shifting of broad biofacies belts, or habitat-tracking, in response to fluctuations of relative sea level, sediment flux, and other associated paleoenvironmental variables. The associations also show strong similarity in terms of their generic composition to biofacies identified in younger sedimentary strata and the modern marine benthic environment in New Zealand.

title: Modelling the behaviour of unemployment rates in the US over time and across space

authors: Holmes, Mark J.

subjects: unemployment

abstract: This paper provides evidence that unemployment rates across US states are stationary and therefore behave according to the natural rate hypothesis. We provide new insights by considering the effect of key variables on the speed of adjustment associated with unemployment shocks. A highly-dimensional VAR analysis of the half-lives associated with shocks to unemployment rates in pairs of states suggests that the distance between states and vacancy rates respectively exert a positive and negative influence. We find that higher homeownership rates do not lead to higher half-lives. When the symmetry assumption is relaxed through quantile regression, support for the Oswald hypothesis through a positive relationship between homeownership rates and half-lives is found at the higher quantiles.

title: Te Aka Roa o Te Oranga, the far reaching vines of wellness: The development of a framework to evaluate alcohol and drug treatment for Māori

authors: Robertson, Paul

subjects: Maori

abstract: The impact of alcohol and other drug
problems for Māori is well documented.
Substance use has been implicated in a
range of physical and mental health
problems, and a variety of negative social
statistics such as high rates of imprisonment. To date there has been
little systematic documentation of treatment
practices, and limited operationalisation of
Māori health frameworks. The evaluation
of the outcomes of alcohol and other drug
treatments is an area in which there is a
paucity of documentation, in terms of
methods and frameworks for evaluation,
and actual data. Te Aka Roa O Te Oranga (TAROTO)
was developed from a range of projects
undertaken by the National Addiction
Centre. The TARATO evaluation framework
embraces a holistic perspective: developed
to examine the interaction between the
client, whānau, practitioner, and
service/organisation. The aim of the
framework is to clarify the complex
relationships and interactions between
stakeholders within the context of
treatment. It will also help to elucidate the
strengths and weaknesses of individual
services. Within this framework, a range of
indicators and outcomes of “successful
treatment” will be explored. The current project is the first phase of
a broader project that will make a
significant contribution to improvements in
Māori health via further developing
effective treatments of alcohol and other
drug related problems.
