The late nineteenth century and early twentieth century were an important period for popular shows involving the moving and projected image, yet there have been few sustained studies that have mapped optical entertainments systematically outside London or that have analysed the influence of such shows on early film exhibition. This thesis has profiled the popular and visual culture of five contrasting South West locations during this period, tracing the development and distribution of magic lantern shows and dioramas as well as identifying the local and touring companies who hosted film on its arrival in the region. Using the local press, the trade press, contemporary publications and ephemera, this thesis has reconstructed an account of local shows and culture which not only deepens our understanding of popular visual entertainments in regional contexts, but which also serves to stand as a comparison to other established urban and metropolitan paradigms and thus to contribute to a wider and more complex national picture. It advances the argument for a broader classification of such shows in response to local findings and for a more nuanced and detailed appraisal and understanding of their provenance and profiles, and the role film played within them. In addition, this thesis interrogates early film exhibition in these resorts following the move to fixed-venue cinemas in the late 1900s and investigates the arrival of cinema and its emergence as a fledgling industry in the region. It offers an overview of investment into the business locally and evidences the varied set of partnerships and individuals responsible for financing the first cinemas here. Responses to the new technologies and local modifications to business models for cinemas and film exhibition are analysed and their diversity examined. Managerial relationships with communities are evidenced as an important contributory factor to the success of many local cinemas, permitting adaptations to the needs of patrons which boosted audiences and increased revenue. The variety of local interpretations of cinema discovered here reflects the social and cultural diversity of these selected sites, and is a key finding of this thesis.

The overall goal of the thesis was to develop and optimize the moving bed biofilm reactor technology under anaerobic conditions. The thesis work was divided into two different series of experiments. Hence, at first, the reactor start-up on synthetic substrate was evaluated and it was proven that the anaerobic moving bed biofilm reactor technology could successfully treat concentrated wastewater. Subsequently, a study on Fort Garry Brewery wastewater was conducted to optimize the process for a typical North American industrial wastewater. The aim was successfully achieved and a potential design to treat Fort Garry Brewery wastewater was developed. The anaerobic moving bed biofilm reactor was found to be capable in treating brewery wastewater with potential savings to the industry paying surcharges for discharging wastewater over the city sewer bylaw limits. / October 2016

This paper introduces ideas and methods for testing for structural change in linear regression models and presents how these have been realized in an R package called strucchange. It features tests from the generalized fluctuation test framework as well as from the F test (Chow test) framework. Extending standard significance tests it contains methods to fit, plot and test empirical fluctuation processes (like CUSUM, MOSUM and estimates-based processes) on the one hand and to compute, plot and test sequences of F statistics with the supF, aveF and expF test on the other. Thus, it makes powerful tools available to display information about structural changes in regression relationships and to assess their significance. Furthermore it is described how incoming data can be monitored online. / Series: Report Series SFB "Adaptive Information Systems and Modelling in Economics and Management Science"

The classical approach to testing for structural change employs retrospective tests using a historical data set of a given length. Here we consider a wide array of fluctuation-type tests in a monitoring situation - given a history period for which a regression relationship is known to be stable, we test whether incoming data are consistent with the previously established relationship. Procedures based on estimates of the regression coefficients are extended in three directions: we introduce (a) procedures based on OLS residuals, (b) rescaled statistics and (c) alternative asymptotic boundaries. Compared to the existing tests our extensions offer better power against certain alternatives, improved size in finite samples for dynamic models and ease of computation respectively. We apply our methods to two data sets, German M1 money demand and U.S. labor productivity. / Series: Report Series SFB "Adaptive Information Systems and Modelling in Economics and Management Science"

Research report presented to SBL, Unisa, Midrand. / The subject on the role of branding in delivering financial growth has been a debate for most marketers and financial managers. This is because the marketing subject by its nature is intangible and therefore difficult to measure. This misunderstanding has resulted in many authors calling for marketing to be accountable and focus on marketing investments that will deliver long term value for the shareholders. This study explores the role of branding in the South African FMCG industry and three main areas are explored namely whether marketing strategies are focused on increasing sales or future business growth. The second area is whether the inclusion of brand equity measures as part of the financial company reports, will give them the focus that they deserve. Thirdly it explores whether there is a link between brand building initiatives and financial measures. A qualitative research method was used as it gave the researcher an in depth understanding of the role of brand management within the FMCG industry and its impact on financial measures. A total of fifteen employees were interviewed using semi-structured interviews. The findings indicate that companies still focus on measures that drive short term gains instead of long term growth and that brand building activities are compromised by brand harming activities such as regular price cutting. Future research to evaluate the impact of marketing activities that drive short term sales on brand equity and subsequently shareholder value is recommended.

This research study investigated the influence of maintaining a partnership form of relationship between a Fast Moving Consumer Goods (FMCG) multinational company and its core suppliers, on their abilities to achieve supply chain agility. It took place within the Middle East region, where the in-depth case study used for data collection was Unilever (North Africa Middle East). The research also focused on the role played by information technology within Unilever’s (North Africa Middle East) partnership with its core suppliers and the achievement of a high level of agility within their supply chain. In addition to these two main aims, the research also focused on exploring the required attributes of supply chain agility within FMCG industry and also to explore the attributes of buyer-supplier partnership required to help the companies working within this type of industry to achieve agility within their supply chain. To achieve the aims and objectives of this research, this study used qualitative methods for collecting rich and valuable data. Several data collection methods under the umbrella of the in-depth case study approach were used. The methodological approach used by the research was the Grounded Theory approach (Strauss and Corbin, 1990-1998). Data was collected from the case study managerial level in Unilever’s (North Africa Middle East) main clusters within the Middle East in three different rounds, using semi-structured interviews. Data was also collected from five core suppliers for Unilever (North Africa Middle East). The research also used other data collection means, such as documents collected during the researcher’s visits to the case studies and observation. Data was analysed using the steps and procedures of the Grounded Theory approach (Strauss and Corbin, 1990-1998). Data analysis took place in three interrelated iterative steps: open coding process, axial coding process followed by the selective coding process, leading to the generated theory of the research. The findings of the study, as presented in the research’s generated theory, showed that the partnership, with its attributes explored during the research, between Unilever (North Africa Middle East) and its core suppliers can be considered as the starting driver helping the companies working within this type of industry to achieve a higher level of supply chain agility, through the attributes explored during the research. The generated theory also showed that the role played by information technology can be considered as the catalyst in this equation. It played the role of channelling the relationship between the two concepts: buyer-supplier partnership and supply chain agility. Information technology can be considered as the catalyst because the evidence indicates that without it the relationship between Unilever (North Africa Middle East) supplier partnership and supply chain agility would struggle to be achieved. In more detailed, 43 open codes had been derived from the first analysis coding process, and which were derived under the main pre-determined themes: FMCGs industry-based features, Buyer-supplier relationships, Information sharing and information technology, and Agility. These 43 open codes provided the basis for stages 2 and 3 of the analysis. In the axial coding process (the second data analysis), the axial sub categories and the axial categories were determined and the axial paradigm model was used in the analysis. In the final coding process: the selective analysis, the core category of the research was determined to be ‘Partnership existence with core suppliers’. The relationship of this core category with the other elements in the paradigm model namely: casual conditions, context, intervening conditions, action/interactional strategies, and consequences. The research has its own Theoretical, Methodological, and Managerial contributions. Among these contributions is that it can be considered a novel research, using a grounded theory approach to generate a theory, showing the relationship between buyer-supplier partnership and supply chain agility in this dimensional manner.

Intercepter une cible en mouvement est un défi spatiotemporel relevé par de nombreuses espèces animales. Ici, nous nous sommes intéressés à la capture fovéale lors de l’orientation saccadique du regard vers une cible visuelle mobile chez le singe vigile. La théorie actuelle propose que l’interception saccadique fasse intervenir deux voies neuronales. Une première voie acheminerait, via le colliculus supérieur profond (CSp), un signal de position échantillonnée au générateur saccadique. La seconde, via le cervelet, fournirait une commande supplémentaire sur la base des signaux de mouvement visuel. Une étude comportementale a été réalisée afin d’analyser la dynamique de l’influence de ces signaux sur la trajectoire saccadique et a permis de mettre en évidence une influence continue. Dans une seconde étude, nous avons testé la robustesse du système oculomoteur à une perturbation spatiotemporelle inattendue (par microstimulation électrique du CSp) et montré la présence de saccades de correction précises. L’ensemble de nos résultats plaide pour une représentation continue du but des saccades d’interception. / Intercepting a visual moving target is a spatiotemporal challenge for the brain achieved by various species. Here, we investigated the foveal capture of a moving target by saccadic gaze shifts in the awake monkey. The current theory proposes that the saccadic interception involves two neural pathways. A first pathway would convey to the saccade burst generator a sampled target position signal through the superior colliculus (SC). The second one, through the cerebellum, would convey an additional command on the basis of motion-related signals. A behavioral experiment was performed to analyze the influence of motion-related signals on the saccade dynamics and allowed showing a continuous influence. In a second study, we tested the robustness of the oculomotor system to an unexpected spatiotemporal perturbation (by electrical microstimulation in the deep SC) and showed the presence of accurate correction saccades. Our results argue for a continuous representation of the saccade goal.

Doctor of Philosophy / Department of Mechanical and Nuclear Engineering / Steve Eckels / A new human thermal model was developed to predict the thermal responses of human body in various environments. The new model was based on Smith's model, which employed finite element method to discretize the human body. The body parts in our new model were not limited to the cylindrical shape as in Smith's model, but subjected to arbitrary shapes. Therefore, the new model is capable of dealing with more complicated shapes of the human body. Steady-state and transient temperatures of fifteen body parts were calculated for three environments: cold, neutral, and warm. Our results were compared with the data from Zhang's experimental research on the human subjects. For all three conditions, our results showed better agreement with experimental data than Smith's results did. The maximal deviation is 1ºC for neutral and warm condition; for cold condition, a maximal deviation of 3.5ºC is reported at hand. The comparison indicated that our new model could provide a more accurate prediction on the body temperatures. Follow-up experiments were conducted to investigate the local and overall heat transfer from a moving cylinder in air flow. This study was expected to provide the local convective heat transfer coefficients of the human body to our new human thermal model to simulate moving humans. An experiment of a stationary cylinder in cross flow was performed to verify the accuracy and consistency of our system. Then, the experiment of a transverse oscillating cylinder in cross flow was conducted, with a oscillation frequency of 0.15 and Strouhal number of 0.3 to 1.5, depending on wind velocity. The overall Nusselt number (Nu) of the oscillating cylinder remained unaffected, compared to the stationary cylinder. This observation showed agreement with previous studies. The pivot experiment was performed to investigate swinging movement of human arms. The cylinder was positioned axially in cross flow, and reciprocated on a fixed point between horizontal and vertical positions under three wind speeds and two oscillating frequencies. The results showed that the overall Nu was between the Nu at horizontal and vertical positions in stationary state. A correlation was presented to predict the Nu of pivotal moving cylinder by using stationary Nu at horizontal and vertical positions. The correlation was proved to be valid ( error less than 5%) within the range of conditions in our experiment.

Doctor of Philosophy / Department of Geography / Douglas G. Goodin / Jesse A. Poland / Kevin Price / Wheat breeders are in a race for genetic gain to secure the future nutritional needs of a growing population. Multiple barriers exist in the acceleration of crop improvement. Emerging technologies are reducing these obstacles. Advances in genotyping technologies have significantly decreased the cost of characterizing the genetic make-up of candidate breeding lines. However, this is just part of the equation. Field-based phenotyping informs a breeder’s decision as to which lines move forward in the breeding cycle. This has long been the most expensive and time-consuming, though most critical, aspect of breeding. The grand challenge remains in connecting genetic variants to observed phenotypes followed by predicting phenotypes based on the genetic composition of lines or cultivars. In this context, the current study was undertaken to investigate the utility of UAS in assessment field trials in wheat breeding programs. The major objective was to integrate remotely sensed data with geospatial analysis for high throughput phenotyping of large wheat breeding nurseries. The initial step was to develop and validate a semi-automated high-throughput phenotyping pipeline using a low-cost UAS and NIR camera, image processing, and radiometric calibration to build orthomosaic imagery and 3D models. The relationship between plot-level data (vegetation indices and height) extracted from UAS imagery and manual measurements were examined and found to have a high correlation. Data derived from UAS imagery performed as well as manual measurements while exponentially increasing the amount of data available. The high-resolution, high-temporal HTP data extracted from this pipeline offered the opportunity to develop a within season grain yield prediction model. Due to the variety in genotypes and environmental conditions, breeding trials are inherently spatial in nature and vary non-randomly across the field. This makes geographically weighted regression models a good choice as a geospatial prediction model. Finally, with the addition of georeferenced and spatial data integral in HTP and imagery, we were able to reduce the environmental effect from the data and increase the accuracy of UAS plot-level data. The models developed through this research, when combined with genotyping technologies, increase the volume, accuracy, and reliability of phenotypic data to better inform breeder selections. This increased accuracy with evaluating and predicting grain yield will help breeders to rapidly identify and advance the most promising candidate wheat varieties.

In accordance with an experimental setup this thesis investigates to what extent the participants' attitudes and aesthetic preferences are influenced by the lateral direction of light in moving image sequences. It is also investigated whether the participants' handedness correlates with their advertising evaluation. The purpose of the study is to generate new knowledge of potential biases in moving images that could be applied by image producers to create more compelling commercials. Our work is based on a transdisciplinary theoretical approach and the results are analyzed based on biopsychological, sociocultural and perceptual explanatory models. Three self-designed commercials with a left oriented illumination position were used as stimulus, the stimulus were also inverted horizontally. The participants were asked to assess their attitudes toward the commercials with either left or right oriented lighting. Two surveys were conducted: one with a within-subjects design and one with a between-subjects design, a total of 172 people participated. No significant difference between left and right oriented illumination position occurred in any of the groups for neither feelings toward ad, Aad , Ab , or PI. The results suggests that a bias does not occur in dynamic images, unlike the left oriented bias that has been reliably shown in previous studies that relate to still images. Nor could any correlation be established between reported attitudes and handedness.
