Brands, and the process of branding, are of considerable importance in both marketing academia and practice. Although most research has focussed on the positive attitudes and behaviours that consumers have toward brands, there is a growing interest in anti-consumption. This thesis contributes to anti-consumption research by exploring the phenomenon of brand avoidance. Earlier studies investigating the avoidance of brands have been one-dimensional, failing to account for the wide range of reasons underlying brand avoidance. Therefore, this thesis addresses the limitations of existing models by providing an integrative and comprehensive approach to understanding brand avoidance. As an anti-consumption phenomenon, brand avoidance concerns the negative interaction between consumers, as social actors, and brands, as meaningful objects, within a social and historical context. Therefore, this thesis adopts an interpretive approach, a social constructionist epistemology, and historical realist ontology. Since research in the immediate area of brand avoidance is limited, this thesis employs a grounded theory methodology to analyse, code, and generate theory from the qualitative data gathered through 23 in-depth interviews. Four main types of brand avoidance (experiential, identity, deficit-value, and moral) and the circumstances in which brand avoidance may be restricted or alleviated (avoidance antidotes) emerge from the data. Existing literatures are used to further inform these findings and an original negative brand promises framework is developed to help increase understanding of the brand avoidance phenomenon. The main components of this research are then integrated into an emergent theoretical model of brand avoidance. This model offers a synopsis of how the various brand avoidance constructs may relate to one another and to other pertinent branding concepts within a consumption system. Combined, the findings of this thesis provide a comprehensive appreciation of why consumers avoid certain brands in addition to potential insights that may be used in the management of brand avoidance. Overall, this thesis contributes knowledge to the growing field of anti-consumption research by providing an innovative overview and an integrative understanding of an under-explored domain, brand avoidance. / Foundation for Research Science and Technology (Project number UOWX0227).

The overall aim of this study was to examine the work environment and the associations with safety, and see the relations with occupational accidents and undesired events on board industrial and cruise ships. 215 seafarers participated in this quantitative survey study, with a response rate of 35%. When conducting the hierarchical block regression analysis separately on superiors/officers and subordinates/ratings, the work environment emerged as a predictor for safety status (compliance, attitudes and commitment). Several significant differences in the beta value between the two groups were also found. When testing the differences in the safety status on ships with high and low number of undesired events and accidents, separately on the two groups, significant differences emerged only for superiors and officers; Significant differences were found in compliance when testing high and low number of undesired events, and for high and low number of accidents safety status and compliance emerged significant. Without assuming causation, the work environment appears to be a possible alternate and indirect way of improving on the safety status on board ships. However, safety status and the relations with undesired events and accidents require further investigation before a more accurate conclusion can be made.

The master’s thesis discusses siphon pipes that are used to collect groundwater. The goal of work is to define the most frequent undesired events that may appear on siphon pipes, and verifying the individual springs. The work is addressed in accordance with the metodology of risk analysis WaterRisk. The content of the work is a summary of the hydraulic of siphon pipes and their use in practice, hazard identification, defining the most frequent undesired events and consequences on siphon pipes, and their verification in the spring in a particular case study.

Higgins (1987) argued that perceived discrepancies between actual-self and ideal-self increase vulnerability to depression. Ogilvie (1987) argued that discrepancies between actual-self and undesired-self are more powerful determinants of depression. To test these claims, and to assess the effects of mood on reported discrepancies, 190 psychology undergraduates completed measures of their actual, ideal, and undesired selves, along with measures of depression (Depression Adjective Checklist and Beck Depression Inventory) and depression proneness (Depression Proneness Rating Scale). Approximately 3 weeks later, 147 of these participants were assigned to either a positive, negative, or no mood induction procedure, and again completed measures of actual, ideal, and undesired selves. Actual-ideal discrepancies were associated with current depression (' r' =.19, 'p' =.008) and with depression proneness ('r' =.28, 'p' =.001). More importantly, the relationship between actual-ideal discrepancies and depression proneness was, to some extent, independent of current mood, as measured by the DACL (partial ' r' =.19, 'p' =.008). <p>Nevertheless, induced moods also affected the reporting of actual-ideal discrepancies, with negative mood induction increasing discrepancy scores and positive mood induction decreasing discrepancy scores (<math> <f> <g>b</g></f> </math> =.49, 'p' <.0005). The above results are qualified by finding that when induced into a negative mood, high depression-prone participants (those with a history of depression) showed greater increases in actual-ideal discrepancies than low depression-prone participants, suggesting that self-discrepancies are cognitive structures that can be made accessible (primed) by mood. Lastly, no support was found for Ogilvie's claim that actual-undesired self discrepancies can be more powerful determinants of depressive vulnerability than actual-ideal self-discrepancies.

Since Shuji Nakamura, Hiroshi Amano, and Isamu Akasaki won the 2014 Nobel prize in Physics owing to theircontributions on the invention of efficient blue GaN light emitting diodes, GaN became an even more appealingmaterial system in the research field of optoelectronics. On the other hand, quantum structures or low-dimensionalstructures with properties derived from quantum physics demonstrate superior and unique electrical and opticalproperties, providing a significant potential on novel optoelectronic applications based on the employment of quantumconfinement.   In 2012, our research team at Linköping University utilized pyramid templates, which is an established approach toform quantum structures, to successfully grow GaN pyramids with InGaN hybrid quantum structures, includingquantum wells, quantum wires, and quantum dots. This growth enabled site-controlled pyramids based on selectivearea growth (SAG). After numerous studies on the photoluminescence properties, the mature and controlled growthtechnique was proposed to be adapted for fabrication of AlGaN pyramids on which GaN hybrid quantum structurescan be hosted.   This thesis is dedicated to the subsequent problems of the growth of AlGaN pyramids. It was found that there wasan undesired deposition of a considerable thickness on top the desired AlGaN pyramid with GaN multiple quantumwells. In this thesis, two different directions are explored to find the key solution with a potential of furtheroptimization. On one hand, the growth parameters such as precursors cut-off, carrier gas during cooling, temperatureholding, cooling pressure, III/V ratio, and the possible effect of GaN surfaces are investigated. However, due to theactual inherent properties of the metal-organic chemical vapor deposition reactor used, no promising parameter tuningcan been identified. On the other hand, from post-growth point of view, a KOH aqueous etching solution exhibits apositive result toward removing the undesired deposition. This etching process is suggested to be further optimized toachieve the final goal of eliminating the undesired deposition.
