An exploration of the creation and use of farmers' commonly used "rules of thumb" is required to conceptualize farmers' decision making processes. While farmers face complex situations, particularly when subsistence is an issue, they do appear to use simple rules in their decision making. To date inadequate attention has been given to understanding their reasoning processes in creating the rules, so this study traces the origins of farmers' beliefs, and extracts the decisive and dynamic elements in their decision making systems to provide this understanding. The analysis was structured by using a model based on the Theory of Planned Behaviour (TPB). Modifications included recognizing a bargaining process (BP) and other decision stimuli to represent socio-cultural influences and sources of perception, respectively. Two analyses based on the Personal Construct Theory (PCT) and the Ethnographic Decision Tree Modelling (EDTM) were also applied to help elaborate the farmers' cognitive process and actual decision criteria. The method involved interviews in two villages in Lamongan Regency in East Java Province of Indonesia, where the farmers adopted an improved paddy-prawn system ("pandu"). The results highlighted that farmers use rational strategies, and that socio-cultural factors influence decision making. This was represented by interactions between the farmers' perceptions, their bargaining effort, and various background factors. The TPB model revealed that the farmers' perceptions about the potential of "pandu", and the interaction with their "significant others", influenced their intention to adopt "pandu". The farmers appeared to prefer a steady income and familiar practices at the same time as obtaining new information, mainly from their peers. When "pandu" failed to show sufficiently profitable results, most farmers decided to ignore or discontinue "pandu". This became the biggest disincentive to a wide and sustainable adoption. However, the PCT analysis showed that part of this problem also stemmed from the farmers' lack of resources and knowledge. The farmers' restrictive conditions also led them to seek socio-cultural and practical support for their actions. This was highlighted by a bargaining process (BP) that integrated what the farmers had learned, and believed, into their adoption behaviour. The BP also captured the farmers' communication strategies when dealing with "pandu" as its adoption affected resource allocation within the family and required cooperation with neighbours. The PCT and EDTM analyses also confirmed how the BP accommodated different sets of decision criteria to form different adoption behaviours. Such a process indicated the importance of considering the adoption decision and the relevant changes resulting from the farmers' cognition. This provided a more dynamic and realistic description of the farmers' decision-making process than has previously been attempted. Overall, the results suggested that semi-commercial farmers need to know, and confirm, that a new technology is significantly superior to the existing system, and can provide a secure income. The introduction of a new technology should use a participatory approach allowing negotiation, conflict mitigation and the creation of consensus among the relevant parties. This can be supported through better access to knowledge, information and financing. A specific and well-targeted policy intervention may also be needed to accommodate the diversity in the farmers' ways of learning and making decisions. Ways to improve the current analytical approaches are also suggested.

This thesis explores the application of personal construct psychology and the repertory grid to performance management in a technical consulting organisation. The research examines what is important for a manager in assessing work performance and how each manager's mental model for performance compares with his/her peers. Managers acting as raters are the critical link in the observation and assessment of performance and in the feedback process. Rater observations and judgements are affected by their personal mental models regarding what is important. These views may or may not accord with those of their peers, resulting in inconsistency and unfair assessments, or with what the organisation's strategy demands. Understanding rater views on what is important, and how well these align with strategy, is a key to ensure that the appraisal process supports, rather than hinders, both individual and organisational needs. Each manager's personal constructs relating to appraisal were elicited through a repertory grid interview. The elicited constructs were taken together and categorised to derive broad performance categories summarising the views of the entire management team. Each individual's personal constructs were then allocated to the relevant common category to develop a view of how each manager related to the group's overall approach to appraisal. A measure for the importance of each category in making performance judgments (importance score) was derived based on the correlation of the constructs in each category with an overall performance construct. A second measure of a manager's preparedness to discriminate between levels of performance was also derived (discriminant score) based on the variation in each manager's construct structure. In keeping with the personal construct psychology approach, the process emphasizes the importance of discussion with the individual concerned to verify the sorting and ranking pro cess. A ranking process to establish the overall management group priorities for judging performance (team mental models) was demonstrated and a charting process was developed to facilitate presentation and discussion of the results. The research has demonstrated the strength of the repertory grid process as a means of getting at a rater's framework for thinking about appraisal and provides a way to identify possible voids or blind spots in a rater's approach. Understanding the most important categories of performance used by raters provides an opportunity for management to determine whether these are likely to achieve the objectives of the company, and if necessary, to introduce and inculcate different approaches.

This paper presents a method for assessing the personal construct systems of young children (ages 4 to 6) regarding the notion of 'nature,' conducted at a Montessori Casa in Toronto, Ontario. Images from the participants' drawings of 'nature' were used in a card sorting exercise and as elements in a modified repertory grid test. Member checking was conducted through recorded conversations with the children throughout the process to minimize the influence of my own construct system. I conducted content analyses of the initial drawings, and made structural measurements and statistical analyses of the card sort and repertory grid data. The limited results indicate that this modified form of repertory grid test is reliable and useful for assessing the structure of young children's construct systems regarding 'nature.' Using Personal Construct Theory may facilitate the development of more participatory, engaging, and effective Environmental Education programs.
