Emotional disorders are common in people with brain damage. It is often difficult to determine whether such disorders are a result of a deficit in recognition, expression, or regulation of emotion due to brain damage per se, or if they are reactive to other functional limitations. The Victoria Emotion Recognition Test (VERT) was developed to provide a standardized tool for the assessment of deficits in the recognition of facial and tonal affect. The VERT was constructed on the basis of neurophysiological and behavioural theories of emotion and neuropsychological theories of agnosia. The VERT consists of three subtests in which four emotions (angry, sad, happy and afraid) are presented at three levels of intensity. The visual subtest presents photographs of faces; the auditory subtest, audiotaped voice clips; and the auditory/visual subtest, both photographs and voice clips. Psychometric results of the standardization studies suggest that the VERT measures an aspect of the recognition of facial and tonal emotion that is independent of more basic skills in face recognition and auditory nonverbal memory. The theoretical construct of recognition of emotion was investigated within the framework of an "affective agnosia". The results suggest that a broader concept of agnosia is necessary in order to include failures in recognition of emotion within this framework. / Graduate

This thesis presents the design and the stability analysis of a hierarchical controller for unmanned aerial vehicles. We utilize non-linear control methodology to command dynamics of unmanned helicopter which has been divided into slower translational dynamics (outer-loop) and faster orientation dynamics (inner-loop), thus exhibiting hierarchical structure. The attitude angles and position which separately belongs to the inner-loop and the outer-loop can be independently controlled by backstepping control strategy. Stability analysis of the helicopter system including applying dynamics has been illustrated after designing. And relative comparison between linear and nonlinear controllers has been carried out. After studying linear control, nonlinear control and stability analysis of one small-scale helicopter, we think about control strategy of a group helicopter which can be called as consensus control.

The thesis tested the notion of collective ownership in the small-scale fisheries sector, as advocated by the Department of Agriculture, Forestry and Fisheries, the South African government department responsible for fisheries administration. More specifically, it examined the conditions under which collective ownership would yield economic benefits to small-scale fishers. This was done according to three constructs, i.e. collective entrepreneurship, agency theory and value chain development. In testing the study’s presuppositions, a sequential qualitative-quantitative mixed methods research methodology was used. Data were gathered through focus group discussions, individual interviews and surveys with fishers from South Africa’s Western Cape and Northern Cape provinces. Qualitative data were analysed through the constant comparative approach preliminary outcomes thereof were used to devise the quantitative instruments, which were analysed with the SPSS statistical package. The outcomes of the quantitative data analysis were then discussed with key participants to validate the findings and to ensure overall congruency. In the current value chain dispensation, small-scale fishers realise approximately 38% of overall revenue accrual, whereas the remaining 62% is realised by fish-processing establishments and exporters. The value chain requires reconfiguration to progressively enable small-scale fishers to own and control all upstream and downstream catch, processing and marketing processes. In addition, greater value can be realised when all regulatory, catch, processing and marketing processes are efficiently aligned with local and export market requirements. The findings note that small-scale fishers require developmental support to exploit opportunities. The study suggests that the required support should be facilitated through a dedicated multi- and interdisciplinary fisheries institute located at a higher education institution. This institute needs to focus on training, advisory services and research, as well as on defined support for the fisheries co-operatives. Moreover, the impact of the envisaged institute provides for the establishment of localised fishing community information centres, located near coastal fishing communities, harbours and slipways. Such centres ought to improve communications, trust-building relations and shared expertise among all actors, namely small-scale fishers, their co-operatives, the various government departments, industrial associations, non-governmental organisations, agencies and all others implicated, to maximise benefit and effectively secure government’s infrastructural investment programme within the small-scale fisheries sector.

To determine proper priorities for the provision of health care in large stadiums, we studied the medical incident patterns occurring in a major college facility and combined this with previously reported information from four other large stadiums. Medical incidents were an uncommon occurrence (1.20 to 5.23 per 10,000 people) with true medical emergencies being even more unusual (0.09 to 0.31 per 10,000 people). Cardiac arrest was rare (0.01 to 0.04 events per 10,000 people). However, the rates of successful resuscitation in three studies were 85% or higher. The previous studies were descriptive in nature and failed to provide specific recommendations for medical aid system configuration or response times. A model is proposed to provide rapid response of advanced life support care to victims of cardiac arrest. We believe that the use of this model in large stadiums throughout the United States could save as many as 100 lives during each football season.

In this study, two hydrologic models were applied to the mountainous Back Creek catchment, located in the headwaters of the Roanoke River in Southwest Virginia. The two models employed were HEC-1, an event based lumped model, and TOPMODEL, a continuous semi-distributed model. These models were used to investigate (a) the issue of spatial scale in hydrologic modeling, and (b) two approaches to modeling, continuous versus event based. Two HEC-1 models were developed with a different number of subareas in each. The hydrographs generated by each HEC-1 model for a number of large rainfall events were analyzed visually and statistically. No observable improvement resulted from increasing the number of subareas in the HEC-1 models from 20 to 81. TOPMODEL was applied to the same watershed using a series of different size grid cells. The first step in applying TOPMODEL to a watershed involves GIS analysis which results in a raster grid of elevations used for the calculation of the topographic index, ln(a/tan b). The hydrographs generated by TOPMODEL with each grid cell size were compared in order to assess the sensitivity of TOPMODEL hydrographs to grid cell size. An increase in grid cell size from 15 to 120 meters resulted in increased values of the watershed mean of the topographic index. However, hydrographs generated by TOPMODEL were completely unaffected by this increase in the topographic index. Analyses were also performed to determine the sensitivity of TOPMODEL hydrographs to several model parameters. It was determined that the parameters that had the greatest effect on hydrographs generated by TOPMODEL were the m and ln(To) parameters. The modeling performances of the event based HEC-1 and the continuous TOPMODEL were analyzed and compared visually and statistically for a number of large storms. The limited number of storms used to compare HEC-1 and TOPMODEL makes it difficult to determine definitively which model simulates large storms better. It does appear that perhaps HEC-1 is slightly superior in that regard. TOPMODEL was also executed as an event based model for two single events and the resulting hydrographs were compared to the HEC-1 and continuous TOPMODEL results. Both HEC-1 and TOPMODEL (when used as a continuous model) simulate large storms better than TOPMODEL (when used as an event based model). / Master of Science

A dissertation submitted to the Faculty of Arts in fulfillment of the requirements for the Degree of Master of Development Studies in the Department of Anthropology and Development Studies at the University of Zululand, 2017 / Primary agriculture is an essential activity that ensures a supply of raw food material. This research study examined small-scale agricultural projects and their role in poverty reduction with particular reference to Cezwana area in Jozini, South Africa. Small-scale agriculture plays an important role in development in this area, not only in terms of income generation, but overall regional economic growth. The agricultural sector has significant potential to transform the Jozini economy. The study examined the possibilities for small-scale agricultural development in Cezwana area and drew on the relevant literature as a framework to understand the agricultural sector in relation to the strategies employed by the government to develop smallholder farms. While it is acknowledged that policies have been adopted to promote food security by ensuring a steady supply of raw food materials to the manufacturing sector, and to create jobs and income, the sector’s potential has yet to be realized. In order to assess the status-quo of small-scale agriculture in Cezwana area and its effect on poverty reduction, data were obtained from Cezwana Youth Cooperative Limited, Zamani Gardening, Isiqalosethu Gardening, and the Department of Agriculture (DoA) in Jozini Local Municipality. The study identified the major factors that constrain the development of small-scale farming and indeed the overall agricultural sector in Jozini such as the neglect of agriculture arising from dispersed zones, inadequate infrastructural facilities and extension services, a shortage of labour, a decline in the quality of land due to climate change, a lack of project management, and policy inconsistency, etc. It recommends the provision of supportive facilities to farmers, as well as transparent extension services, price stabilization and prioritizing and building small-scale agriculture to ensure that this sector takes its rightful place in South Africa’s economy and contributes to poverty reduction.

Trunk poetry is an investigation of a tree, its natural form shaped by its environment, how it can be disassembled and understood through different methods and tools, and how its parts can be reassembled to form structural elements based on the capacity of the natural forms. This research consists of three phases which are a combination of a historical perspective on identifying and harvesting construction timber, digital processing such as photogrammetry and physical experiments connected to the construction of structural elements. The focus has been on the natural capacity of the tree, identifying possible architectural or structural functions for its different parts, and from there experimenting on how they could be combined in a structure. Based on the references I have used, and my own research in this thesis, I strongly believe that photogrammetry could be a viable method to investigate a tree and test it digitally in an early stage. Instead of deforesting large areas at the same time, with small percentages being useful for construction of houses, it could give us a possibility to do tests on trees still standing in the forest.
