title: Investigation of a 'Field Factory' to harvest and grade tree stock in a forestry nursery

authors: McGuinness, Benjamin John

abstract: Primary industries are facing an ever increasing labour problem. Major concerns with labour include lack of staff training, high costs, poor efficiency, non-optimal quality control and health and safety issues. While automation is commonplace in factory environments, such technologies have not yet migrated to an outdoor, agricultural environment. Forestry nurseries are no exception, where the most problematic and labour intensive task is lifting and grading tree stock.

Mechanical lifting of tree stock is already performed commercially; however, these machines are incapable of performing the additional steps required by this research, particularly root trimming, coupled with a machine vision system that can replicate the human decision making process for selecting ’good’ and ’bad’ tree stock. In particular, there are strict criteria for root structure which must be assessed. Currently, human graders are proving to be poor assessors of this, to such an extent that tree stock is graded up to three times before being shipped to the customer. Additionally, there is the need to remove expensive pack houses. This research investigates a field factory capable of processing forestry tree stock in the field, from lifting through to grading and boxing. 

The machine vision component of the field factory was tested in controlled conditions, on a sample of 200 trees. There was good agreement between machine vision measurements and manually measured tree features. There is much ambiguity in the grading process, with three experts only reaching a consensus 75% of the time when grading a sample of trees. The machine vision grading system performed very well, showing less bias than human graders.  The machine agreed with the specification 96% of the time, significantly higher than the experts’ agreements of between 86 and 90%. While classification systems such as fuzzy logic and artificial neural networks seem to be a good match for this research, they did not outperform the ’crisp’ grading system.

A field factory for harvesting and grading forestry tree stock proved to be feasible; however, further development, particularly on mechanical systems, is required to produce a machine reliable enough to be implemented commercially.

title: Institutional work and the interplay of stability and change in public budgeting reform: the case of public universities in Iran

authors: Aliabadi, F. Jalali

subjects: Social Sciences

abstract: Purpose: The purpose of this study is to understand the efforts of key social actors in influencing the reform of Iranian public universities budgeting system, from incremental to performance-based budgeting (PBB), the tensions that arose as competing efforts of institutional change were undertaken, and ultimately the impact of these efforts on of the extent to which the Iranian government transitioned to a system of PBB in public universities.
Design/methodology: Data comprises of semi-structured interviews with managers and experts involved in the budget setting process and an analysis of budgetary policy documents, reports and archival material such as legislation. An institutional work lens is employed to interpret the findings. 
Findings: While actors advocating the change were engaged in institutional work efforts of disrupting the old budgetary rules by disassociating the rules moral foundations and creating new budgetary rules (through new legislation), universities undertook subtle resistance by engaging in extended evaluation of the new proposed PBB rules to maintaining the old budgetary rules. The reforms undertaken to introduce PBB in Iranian universities achieved minimal success whereby incremental budgeting continued to constitute by far a larger percentage of the budget allocation formula for university budgets. This finding illustrates change and continuity in university budgetary systems resulting from institutional work of actors competing for control of resource allocation basis under the proposed PBB but proposing contradicting models. 
Practical implications: The findings highlight the importance of understanding the interplay of institutional work undertaken by competing social actors as they seek to advance their goals in shaping the budgetary reform in the public-sector. Such an understanding may inform policy makers who intend to introduce major reforms in public-sector budgeting approaches.  
Originality: Unlike prior studies that largely focused on how organisation-level budgeting practices responded to changes in public budgeting rules (i.e., at the site of implementation of the rules ), this paper highlights how strategies of change and resistance are played out at the site of setting budgetary norms.

title: Kaumtua Mana Motuhake: A study protocol for a peer education intervention to help Māori elders work through later-stage life transitions

authors: Oetzel, John G.

subjects: Science & Technology

abstract: Background
The Aotearoa/New Zealand population is ageing and numerous studies demonstrate with this phenomenon comes increases in non-communicable diseases, injuries and healthcare costs among other issues. Further, significant inequities exist between Māori (Indigenous peoples of Aotearoa/New Zealand) and non-Māori around poor ageing and health. Most research addressing these issues is deficit oriented; however, the current research project takes a strengths-based approach that highlights the potential of kaumātua (elders) by asserting mana motuhake (autonomy, identity and self-actualisation). We believe that the esteem of elders in Māori culture signals transformative potential. Specifically, this project utilises a ‘tuakana-teina’ (older sibling/younger sibling) peer-educator model, where kaumātua work with other kaumātua in relation to health and wellbeing. The objectives of the project are (a) to develop the capacity of kaumātua as peer educators, whilst having positive impacts on their sense of purpose, health and wellbeing; and (b) to enhance the social and health outcomes for kaumātua receiving the intervention.

Methods
The research is grounded in principles of Kaupapa Māori and community-based participatory research, and brings together an Indigenous community of kaumātua, community health researchers, and academic researchers working with two advisory boards. The project intervention involves an orientation programme for tuakana peer educators for other kaumātua (teina). The research design is a pre- and post-test, clustered staggered design. All participants will complete a baseline assessment of health and wellbeing consistent with Māori worldviews (i.e., holistic model). The tuakana and teina participants will be divided into two groups with the first group completing the intervention during the first half of the project and the second group during the second half of the project. All participants will complete post-test assessments following both interventions allowing comparison of the two groups along with repeated measures over time.

Discussion
The findings will provide an evidence base for the importance and relevancy of kaumātua knowledge to create contextually based and culturally safe age-friendly environments that facilitate engagement and participation by kaumātua for kaumātua. If the model is effective, we will seek to facilitate the dissemination and scalability of the intervention.
