The aim of this research is to produce information on decision making in relation to fertiliser use. This information can be used in the Game Theory model to calculate optimal strategies on phosphorus fertiliser application amounts for the individuals within the group. If the results indicate a benefit to the individual and the community as a whole, and are seen as practical, then on a catchment wide basis this should lead to changes in management practices that will minimise phosphorus pollution of the Hopkins River catchment’s waterways.

The objective of this thesis was to investigate the development of a micro-electromechanical system (MEMS) which can be implanted in the eye to provide continuous monitoring of glaucoma conditions. Current glaucoma monitoring involves taking laboratory based intra ocular pressure (IOP) measurements. The measurement of intraocular fluid flow and IOP parameters related to blockage formation in the eye require to be continuously monitored in Glaucoma.

This project examines how the moving image can be used as a vehicle of memory, to express what is lost, what is gained and what changes occur in relation to personal family migratory history—a messy and ambiguous process. This practice-led research project investigates video work, using filmed materials and objects, to focus attention on the non-linear aspect of time as it is subjected to individual and collective memories. The outcomes highlight the sometimes disconnecting and unpredictable experiences of migration, storytelling, and memory.

This research develops a rich theoretical and empirical understanding of embeddedness by way of three dimensions (structural, relational and cultural), and investigates its implications for actors’ value co-creation behaviours and value-in-context outcomes. In addition, the research refines co-creation perspectives by examining a central boundary condition of co-creation processes. The data was collected in an online service environment and was analysed using structural equation modelling techniques.

This thesis develops two objectives. The first objective is to develop a new improved measure for DRPTs. To achieve the first objective, this thesis develops and tests a measure that seeks to distinguish the proportion of transactions in total RPTs that is discriminatory from the proportion that is based on legitimate business motives. The second objective of the thesis is to investigate the effectiveness of Bangladesh’s 2006 reforms for protecting minority shareholders from DRPTs. For this Oliver Williamson’s Market and Hierarchy model is used as a theoretical framework.

This study addresses the question: “How do small and medium Asian grocery retailers (SMAGRs) manage their relationships with suppliers in relation to their power positions under different circumstances?” Using the Kraljic matrix as its analytical base, this study incorporates power relations, in addition to the strategic importance and supply risks of the items purchased, as a third dimension to examine the relationship management strategies SMAGRs used to deal with different suppliers.

This thesis provides a first step towards understanding how fear of crime, perceived risk, perceptions of unsafety, and avoidance behavior reciprocally and positively influence each other; and how personal characteristics and community-related factors influence threat of victimization within a nonrecursive frame of reference, laying the groundwork and advancing conceptual foundations upon which threat of victimization can be assessed.

The main aim of "Doctoral thesis of Philosophy: Prejudicial related-party transactions of listed companies in China: evidence of motivating and enabling influences" is to test theory-driven models of motivating and enabling influences on the extent of prejudicial RPTs. A supplementary aim is to update the descriptive evidence on the incidence and categorisation of RPTs in China.

This research has two main contributions to current knowledge. The first one is its definition of economic impacts of bridge damage in a flood event. The second one is its application of existing knowledge and models to measure the majority of these economic impacts. Future research can focus on understanding the relations between damage states, repair methods, and repair quantities. Also, future research can make a contribution to knowledge of measuring losing trust on authorities.

The increasingly important role played by family firms in China’s fledging capital market calls for a better understanding of how it works and is governed. This study aims to explore how corporate governance issues in family firms are tackled from the perspective of investor protection. The thesis addresses the question by first presenting theoretical models showing the relations among investor protection, family governance, and agency costs in family firms.

As more Koreans invested in Vietnam, the number of foreign students in Korea increased due to the perception that studying in Korea would be beneficial for employment within Vietnam. Also, the ratio of international students entering graduate school is increasing. In this study, the researches related to Vietnam were investigated, focusing on the articles and papers of journals searched through the Vietnam keyword of the National Assembly Library. We also have examined research trends through Big Data Analysis.

The thesis is devoted to constructing and evaluating versions of the SM extended with an A4 symmetry to explain some of the problems of neutrino physics. Within these extended models, the results on neutrino masses and mixing, derived by the perturbation method, are very closed to the global fit. In two models, a relation between the Dirac CPV phase and the mixing angles is established. In particular, the models predict Dirac CPV phase δCP and effective mass of neutrinoless double beta decay jhmeeij in good agreement with the current experimental data.
