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.

The aim of this research is to investigate characteristics of accident denominators across age groups in mining and associated process industries in the Port Hedland region of Western Australia. Emphasis has been focussed on comparing young, inexperienced groups with older, more experienced groups. A literature review revealed some key contributors to accidents among younger workers, in particular, those who had only recently entered the workforce. The review also revealed contributors impacting accidents regarding other age groups over a wide range of industry types. From these findings an accident construct model and questionnaire were designed to identify contributing and mitigating denominators which input to accidents occurring across the defined age groups.

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.

<p>The overall address of the present thesis is the relationship between being ‘on fire’ and burning out. More specifically, the thesis focused largely on two representations of involvement in work (work engagement and Type A behavior) and their respective relationships to burnout. Another pervasive theme was construct validity in assessing burnout and work engagement. These themes were addressed in four empirical studies, conducted in a sample of health-care workers (Study I) and a sample of information communication technology consultants (Studies II, III, and IV). Study I aimed to extend the previously preliminary support for the construct validity of the Swedish version of the Maslach Burnout Inventory (MBI). The objective of Study II was the discriminant validity of the Utrecht Work engagement Scale (UWES) against the theoretically adjacent constructs job involvement and organizational commitment. Another objective was the translation and evaluation of a Swedish version of the UWES. In Study III, the aim was to investigate (cross-sectional) association between Type A behavior, work engagement and burnout. Study III had two foci: 1) whether Type A behavior interacts with job factors to affect burnout and work engagement, and 2) the associations between the main components of Type A behavior (achievement-striving and irritability/impatience) and burnout as well as work engagement. Study IV concerned the longitudinal relationships between Type A behavior and burnout, and between work engagement and burnout. The results presented in this dissertation supported the construct validity of Swedish versions of the MBI and the UWES. It was further indicated that emotional exhaustion and depersonalization (or cynicism) constitute the core aspects of burnout, and that work engagement was more prominently associated with lack of health complaints than job involvement and organizational commitment. Type A behavior was found to be associated with burnout and work engagement in cross-sectional data, however different aspects of Type A behavior appeared to have somewhat different association with burnout and work engagement respectively. The achievement-striving aspect of Type A behavior was related primarily to work engagement, whereas irritability was associated with less engagement and more burnout complaints. No indications of an interaction between Type A behavior and job stress were found. The most important finding of Study IV was that change in Type A behavior was unrelated to change in burnout across time (one-year interval). Furthermore, Study IV supported the notion that work engagement and burnout are bipolar opposites and constitute a work well-being continuum. To conclude, the present thesis suggests that burnout should be viewed as an erosion of intrinsic, affective engagement in work occurring when intrinsic motivation is frustrated by job stress. To avoid conceptual confusion, burnout should be distinguished form exhaustion syndrome however it should be acknowledged that burnout may have negative impact on health. The present study indicated that Type A behavior is unrelated to the specific burnout reaction, a finding that needs to be replicated before generalizability can be assumed. However, it was assumed that Type A behavior represents an instrumental approach to work, further corroborating that burnout is a specific construct referring to the draining of a specific energetic and affective state. This does not imply that Type A behavior is unrelated to health deterioration – most plausibly, Type A behavior generates exhaustion and fatigue from over-exertion of energy. Both research and practice would benefit from exploring how work engagement may best be enhanced using job redesign.</p>

Racism has been identified as a profoundly traumatic and a psychologically damaging experience affecting Black people (Harrell, 2000; White & Parham, 1990; Williams & Williams-Morris, 2000). It has been theorized that one of the most devastating effects racial oppression (i.e. racism and discrimination) is the internalization of that oppression (Bailey, Chung, Williams, & Singh, 2006; Speight, 2007). Speight (2007) argued that an understanding of racism would be incomplete without considering how it is internalized. Internalized racial oppression is the process through which Black people consciously and unconsciously internalize and accept the dominant White culture’s oppressive actions and beliefs towards Black people, while at the same time rejecting an African worldview and cultural motifs (Bailey, Chung, Williams, & Singh, 2006). Internalized racial oppression is believed to adversely affect the psychological health of Black people. This study examined the construct validity of the Internalized Racial Oppression Scale (IROS; Bailey et al., 2006) through the use of confirmatory factor analysis and social desirability. Additionally, this study investigated internalized racial oppression as a predictor of the endogenous factors of Psychological Distress, Psychological Well-Being, Personal Self-Esteem, Collective Self-esteem, and Life Satisfaction through the use of latent variable path analysis. It was hypothesized that, similar to racial oppression; greater levels of internalized racial oppression will predict greater psychological distress, lower psychological well-being, lower personal self-esteem, lower collective self-esteem, and lower satisfaction with life among Black college students. Three hundred seventy Black students (Cohort 1 = 102, Cohort 2 = 268) participated in this study. Cohort 1 consisted of students recruited from a predominately White university in the Southeastern region of the United States. Cohort 2 consisted of a national sample of students. Participants from Cohort 1 completed a pencil and paper survey, while the participants from Cohort 2 completed a survey via online. The results supported the factorial structure of the IROS. Further, the results found that the IROS was a predictor of psychological distress, psychological well-being, collective self-esteem, and satisfaction with life. Implications for research and practice are discussed.
