This thesis investigates consumer perceptions of a Chinese luxury fashion brand in Sweden. The impact of nation brand image in terms of consumer buying behaviour and perception is examined by performing a case study of Shanghai Tang, comparing it to the American luxury fashion brand Ralph Lauren through the brands’ country of origin and brand history. Then a questionnaire is developed to analyse the luxury consumers’ perception of the Chinese brand Shanghai Tang and calculate the probability of customers purchasing luxury goods by Shanghai Tang. Finally, the future of Chinese luxury in Sweden will be discussed through an in-depth interview.

Salmonids naturally organise into social hierarchies both in the wild and aquaculture. This thesis investigates how social rank influences the physiology and development of salmonids with different life strategies using Atlantic salmon (Salmo salar) as a model. In broad terms two types of studies were conducted. Firstly osmoregulatory traits of freshwater parr prior to smolting, maturing or remaining immature where investigated using Na+ gill uptake kinetics. Highly distinct patterns emerged, especially for Na+ uptake affinity, between future alternative phenotypes, which could potentially be used as an identification tool in otherwise visually identical fish. Examination of Na+ uptake kinetics from a social status perspective revealed that first and intermediate ranked fish, which received less aggression and had lower cortisol, were better prepared for sea water entry. In the second batch of studies brain serotonergic activity (5-HIAA/5-HT), a key regulator of agonistic behaviour in vertebrates, was examined in a range of social conditions. First, the stability of social ranks was tested by food manipulation. The most dominant fish were able to retain their high status even after being kept in nutrient poor conditions. High status was associated with a high standard metabolic rate (SMR) and low brain 5-HIAA/5-HT. Secondly, studies on hierarchies with marked bimodal size asymmetries showed that upper modal group fish (UMG) became dominant. Despite being subordinate lower modal group (LMG) individuals showed similar growth rates, serotonin turnover and cortisol to UMG fish, possibly due to high aggression and fin injury sustained by high rank fish fighting for dominance. Thirdly, the association between social dominance and developmental pathway was examined in size-matched groups of immature parr and precocious parr, with the latter obtaining higher social positions and showing higher aggression. Brain serotonin turnover revealed higher 5-HIAA/5-HT in immature parr, a phenotypic distinction that was also identified in immature salmonids in aquaculture. Plasma samples from alternative life histories (immature parr, precocious parr and smolts) were also used for a preliminary investigation of potential metabolite signatures utilising metabolomic techniques.

This study has demonstrated that the phenomenon of acoustic emission can be used to detect and monitor first time deformation characteristics in stiff, heavily-overconsolidated clay soils. The results from two field studies are presented and discussed with the aim of identifying the mechanisms responsible for the generation of acoustic emission. The first study, conducted at the Building Research Establishment's test site at Cowden (Humberside), was a section of cliff, naturally eroded by sea action. The second study, conducted in a 'moth-balled' brick-pit in Arlesey (Bedfordshire), was a large scale test in which instability was induced in a cut slope (in the Gault Clay) by cutting away at the toe. A number of different designs of wave guide were installed at both sites in order to determine the relative performance of each and, also, to provide further insight into the generation mechanisms. Some consideration has also been given to the effect of alternative data processing techniques. The results obtained indicate that the active wave guide model is the more appropriate in explaining the occurrence of acoustic emission and this finding is supported by the results of laboratory tests designed to replicate the perceived role of the wave guide in the field. In itself, identification of the generation mechanism is a result but, more importantly, understanding of the mechanics enables the design of monitoring systems which are suited to particular geotechnical conditions. Some comparison is also made between acoustic emission and standard methods of deformation monitoring. It is observed that acoustic emission can detect and clearly indicate disturbances at the same time as standard methods record such small magnitudes of movement as to be indistinguishable from instrument error. Additionally, a number of triaxial shear tests were conducted on a selection of soils which illustrates that different soils do exhibit different acoustic characteristics. Finally, this study demonstrates the feasibility of envelope processing using analogue to digital signal conversion both in the field and laboratory. Four published papers pertaining to work described within this thesis are appended.

This qualitative study attempted to develop a process theory of suicidal behaviour. The Arthur Inman diary, which documents the thoughts and feelings of a suicidal individual (Arthur Crew Inman) who eventually died by suicide, was the primary data source from which the theory emerged. Aspects of the qualitative grounded theory procedure were used to develop the theory. Purposeful intensity sampling, theoretical sampling, open and discriminant sampling were applied at different stages of the research process. In addition, the constant comparative method, which forms the hallmark of grounded theory procedures, was an integral part of the analytic procedure. The emergent process theory, which was firmly grounded in the primary data source and extant literature sources, hopefully offers a new paradigm within which suicidal behaviour can be understood. It proposes the processional aspects of suicide and puts forward phases, which a potentially suicidal individual goes through. It thus attempts to bridge a major gap in the study of suicidal behaviour by providing dynamic pathways that link vulnerability to suicide with the suicide act. / Thesis (M.Soc.Sci.)-University of KwaZulu-Natal, Pietermaritzburg, 2002.

Transition dairy cows are vulnerable to negative consequences of depressed feed intake due to a transient state of negative energy balance that predisposes them to disease after calving. Competition has been identified as one factor that can decrease feeding activity in mid-lactation cows, but the effects of competition on the transition cow are less well understood. The objective of this study was to test the effect of a competition on the behaviour and feed intake of transition cows. Standing behaviour, feeding behaviour and dry matter intake (DMI) was monitored from 1 wk before to 2 wk after calving for 110 Holstein dairy cows. Social behaviour was recorded in the week before calving. Cows were assigned to a competitive (2:1 cows:bin) or non-competitive (1:1 cow:bin) treatment at the start of the study. Treatment groups were balanced for parity and baseline feeding data, resulting in 8 primiparous and 10 multiparous cows per treatment. Competition dramatically increased the number of agonistic behaviours between cows at the feeder. Primiparous cows showed no change in either feeding or standing behaviour when fed in a competitive environment; however, they increased their total meal duration and within-meal intervals in the wk -1 before and wk +1 after calving. In wk -1 before calving, competitively fed multiparous cows increased the frequency of visits to the feeder but consumed less feed at each visit, resulting in decreased daily DMI. Throughout the experiment, multiparous cows fed competitively spent less time eating at each visit and ate at a faster rate, particularly during the 2 wk after calving. Multiparous cows on the competitive treatment also increased the time they spent standing (without eating) compared to cows on the non-competitive treatment. Feeding rate was negatively correlated with social status in multiparous cows. In summary, the results of this study indicate that restricting access to the feeder increases agonistic behaviours regardless of parity, and cows of different parity and social status respond differently in terms of feeding and standing behaviour.

This thesis is an investigation of the objective assessment of pain through the use of pressure algometers and rumination tags and the effects of pain management therapy for experimentally-induced mastitis on behaviour and physiological measures in dairy cattle. Twenty-four lactating Holstein cows were enrolled in a lipopolysaccharide (LPS) endotoxin challenge study, where one mammary quarter was infused with 25 µg of Escherichia coli (E. coli) LPS endotoxin. Subsequently, a subcutaneous injection of either a non-steroidal anti-inflammatory drug (NSAID) (meloxicam; n=12) or placebo (n=12) was randomly allocated and administered using double-blind methods. Several behavioural, physiological and performance parameters were monitored throughout the study period. Beneficial effects of meloxicam administration on pain sensitivity, edema scores and dry matter intake were shown. For a subset of animals receiving placebo treatment, the algometer and rumination tags accurately detected changes in both pain sensitivity and rumination time after endotoxin challenge. / Canadian Bovine Mastitis Research Network and Boehringer-Ingelheim, Canada

The current studies addressed two questions regarding early social behaviour in children with Autism Spectrum Disorders (ASD) that have not yet been directly explored. In Study 1 we examined the hypothesis that impaired imitation in this group may reflect a diminished social motivation to engage, rather than a core deficit in imitation. Young children with and without ASD engaged in imitation tasks during which controlled manipulations of reward (social and non-social) were administered for target behaviours. Children with ASD displayed increased levels of imitation with the incentive of an external reward in comparison to when this reward was absent. There was no differential impact of social versus non-social rewards. Typically developing (TD) children performed similarly, irrespective of whether or not reward was administered. We suggest that young children with ASD may be capable of imitating when appropriate incentives are present. Study 2 explored the breadth of social challenges faced in young children with ASD by examining a later-developing domain of social functioning that may be compromised by early social difficulties. We explored the tendency of children with ASD to engage in helping, sharing, and comforting behaviour in situations where the need for the prosocial behaviour was displayed and in perceptually similar situations where the need was absent. Children with ASD displayed low levels of helping and sharing, but provided comfort at levels consistent with TD children. For both comforting and sharing, children with ASD successfully discerned situations where a need was present from when it was not and adjusted their behaviour accordingly. We suggest that children with ASD may require different ‘conditions’ to engage in social behaviours at the same level as their TD peers and suggest future research to this end. / Thesis (Ph.D, Psychology) -- Queen's University, 2012-09-27 22:10:12.095
