title: Modelling the effects of Po River discharge, internal nutrient cycling and hydrodynamics on biogeochemistry of the Northern Adriatic Sea

authors: Spillman, C.M.

subjects: ELCOM–CAEDYM

abstract: This study investigates the coupling of physical and biological processes in the Northern Adriatic Sea through use of a dynamic mass balance approach derived from an interdisciplinary model of hydrodynamics and water quality. Emphasis is placed on modelling the role of nutrient inputs from the Po River and the response of phytoplankton concentrations and distributions, and basin-wide nutrient fluxes. The effects of riverine inflows, seasonal stratification and meteorological forcing were assessed with a dynamically coupled 3D hydrodynamic (ELCOM) and ecological (CAEDYM) model after validation with in situ field and remote sensing data. Model simulation results and mass balance calculations indicate a close coupling of physical and biological processes over a range of space and time scales. Comparison of fluxes from advection and particulate organic matter sedimentation indicate that nutrient and phytoplankton levels of the Northern Adriatic Sea are sensitive to variations in riverine nutrient loadings. A net total phosphorus accumulation of 4.61 × 10 kg⁶ was determined for the basin in 2002, with different climate scenarios and riverine nutrient loadings resulting in varied system responses reflected in this net TP accumulation. Changes in net accumulation of nutrients are considerably lower than variations in nutrient loadings, which suggests that the Northern Adriatic has substantial buffering capacity.

title: Human capital in remote and rural Australia: The role of graduate migration

authors: Corcoran, Jonathan

subjects: Australia

abstract: In this paper we examine the spatial employment patterns of Australia's university graduates in nonurban locations. Using a 2006 data set recording the employment status of 65,661 university graduates 6 months after their graduation we examine how the personal and human capital characteristics of the individual university graduate affect the type of rural location into which he or she enters for employment purposes. The importance of identifying which types of graduates work where is essential for our understanding of the forces that are currently shaping the spatial distribution of human capital across Australia's regions. In order to do this we allocate postcode-based data of graduate employment to one of five remoteness classes, as defined by the Australian Bureau of Statistics, that allow us to distinguish between different degrees of rurality. The postcode data are used to associate the ways in which the human capital characteristics of the graduate in terms of the types of university degrees awarded and the universities attended, as well as the personal characteristics of the graduate, are related to the degrees of rurality in his or her employment outcomes.

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.
