abstract: Climate change, land use change and invasive species are transforming global biodiversity at multiple scales. Projections are for threats to biodiversity from these global changes to continue into the future, with varied and discernible distribution changes for many species. Concomitantly, these global changes will interact with each other to further exacerbate the problem, as exemplified in this study. In New Zealand, climate change is expected to affect landscapes, fragmented and disturbed by land use change, further increasing the potential invasibility of these landscapes for a suite of existing and emerging invasive species. 

This thesis is concerned with the combined effects of climate and land use changes on the spatial distribution of the sub-tropical invasive plant, Tradescantia fluminensis (Vell.). The contribution of this thesis is to undertake an integrated assessment of the distribution change for this species in New Zealand. On the basis that climatic variables affect species distribution at larger scales, while land use, habitat, disturbance and dispersal mechanisms affect distribution at smaller scales, two separate analyses were undertaken. At the national scale BioCLIM and the Ecological Niche Factor Analysis (ENFA) were implemented using the variables: minimum temperature (July-August), MTminJ-A, and annual water deficit (November-February). At the landscape scale, only ENFA was implemented, using the variables: MTminJ-A, ECOSAT riparian classes (habitat) and proximity to roads, urban areas and streams (disturbance and dispersal sources). Three scenarios of climate change (CCSR B1-Low, CSIRO9 A1B-Mid and HadCM A1FI-High) and two scenarios of land use change (SmartGrowth and Buildout) were developed to the year 2050, using the CLIMPACTS Open Framework Modelling System and Geographic Information Systems, GIS, techniques respectively. The baseline species distribution model was extrapolated in ENFA, using the 2050 scenarios. Changes to potential threat from this species to protected areas at the landscape level were assessed spatially at the landscape level. This approach and its results are novel for this species.

At the national scale the results for the modelling show that climate change will increase the potential habitat suitability of Tradescantia under all combined scenarios of CCSR, CSIRO9 and HadCM for mean minimum temperature (July-August), MTminJ-A and Annual Water Deficit, AWD. At the case study landscape, in the Western Bay of Plenty and Tauranga also the modelling results showed that climate change and land use changes will increase the suitability for Tradescantia by 2050. 

The 'core' or highest suitability areas increase under all future scenarios. At the national level core suitability increased by about 13% for the CCSR:B1-Low and CSIRO9:A1B-Mid and 22% for HadCM:A1FI-High combined scenario on the North Island. On the South Island, core areas increased by a much lower margin - 1.4%, 2.3% and 2.9% for CCSR:B1-Low, CSIRO9:A1B-Mid and HadCM:A1FI-High combined scenarios respectively. At the landscape level core areas increased by 5%, 8% and 21% for the CCSR:B1-Low+SmartGrowth, Darlam:A1b-Mid+SmartGrwoth and HadCM:A1FI-High+Build-out combined scenarios, respectively. This is true also for the Protected areas within the case study landscape, and indicate that the increasing if Tradescantia is able to track both climate and land use change through its dispersal and migration within the landscape 9 primarily in the inland and upland direction), then is will pose a greater risk to native habitats than at present.

Integrated assessments and the outputs they produce are essential to exploring anticipated changes (through scenario-building) and in understanding the change spatial context and magnitude of projected changes from the combined effects of climate and land use changes into the future and need to be integrated into biodiversity-biosecurity management at multiple scales.

title: An exploration of the use of coaching and
mentoring as a professional development
process for primary school emerging leaders:
Using science as a context

authors: Barnett, Jane Sandra

subjects: Coaching

abstract: This study looks at the impact of coaching and mentoring skills, provided through a professional development programme, on developing emerging middle leadership in primary school teachers, where the focus is on science teaching. Emerging leaders play a very important role in supporting and developing other teachers' pedagogy in the implementation of the curriculum and new initiatives into the classroom. The literature illustrates that the skills for coaching and mentoring form a key part of a leader's role, in particular that of an emerging leader where teachers are coaching teachers. These skills can assist in the formation of professional learning communities with a strong focus on the teachers' practice and the enhancement of student learning outcomes. 
The study involves four teachers (emerging leaders) from four large primary schools. It uses a qualitative approach, with an action research methodology. The tools used for data gathering are a questionnaire, semi-structured interviews, focus group interviews and written journal reflections at the workshops. The data is thematically analysed.
The findings emphasize the value of coaching and mentoring skills in the professional learning of emerging leaders and the teachers that they are working with. Two overarching changes in the emerging leaders' practice arose. Firstly changes in the leadership understandings of the emerging leaders and secondly in the growth of their leadership practice as they developed small professional learning communities. The importance of trust and relationships as part of the community was highlighted. The data also identified a change in the depth and the development of talk about the teachers' science pedagogy. A crucial realization for the participants was the difference between professional and social conversations when it came to taking a leadership role. 
The implications of this research include the importance of providing emerging middle leaders in primary schools with the opportunities to explore the bigger picture of leadership. Senior school leaders would be advised to provide professional development opportunities to help emerging leaders develop in their understanding and practice of the skills and knowledge base involved in the leadership process. This study has illustrated that a coaching and mentoring approach to fostering professional learning can be effective in the growth of leadership skills.

title: Te Rau Puawai 2002-2004: An evaluation

authors: Nikora, Linda Waimarie

subjects: evaluation

abstract: Established in 1999 as a joint workforce initiative between the former Health Funding Authority and Massey University, Te Rau Puawai aimed to support 100 Maori students to graduate with mental health qualifications within a five year period. The goal of Te Rau Puawai is to contribute to the building of capacity for Maori in the mental health workforce. The programme exceeded its performance expectations in the first two years (1999-2001) with 56 bursars completing their qualifications. Bursars achieved an 80% pass rate compared with 65% for all students at Massey University as a whole. In 2004, this pass rate has continued, a significant achievement in light of increasing numbers of bursars being accepted and many without previously studying at the tertiary level.

In 2001 the Maori & Psychology Research Unit (MPRU) at the University of Waikato undertook an evaluation of Te Rau Puawai reporting on the programme's success and identifying any barriers the programme needed to address. The 2002 evaluation report outlines critical success factors and recommendations for improvement. In 2003 Te Rau Puawai negotiated further funding from the Mental Health Directorate (MeHD) of the Ministry of Health under the Mental Health Workforce Development Strategy (2002). Workforce development is critical in building capacity and capability in the mental health workforce to increase appropriately skilled workers required to meet the mental health needs of Maori communities. In 2004 the Ministry of Health requested a follow-up evaluation to provide a descriptive record of programme activities and progress from April 2002 to December 2004. This report provides an overview of Te Rau Puawai activities between 2002 and 2004; the progress and contributions made by bursars to the mental health workforce; and a reassessment of the programme's critical success factors.
