  • Description: Significant differences between countries were found in the distribution of the number of hamuli within Apis andreniformis, A. florea, A. cerana and A. koschevnikovi. The mean hamuli numbers for Apis mellifera intermissa differed significantly among localities in Algeria. Significant differences in intercolonial variability between countries were found within A. cerana. There was no significant infraspecific variability within A. andreniformis, A. florea, A. koschevnikovi and A. m. intermissa. Significant differences in the mean number of hamuli occur between A. m. intermissa and A. andreniformis, A. florea and A. cerana; also between A. cerana/A. koschevnikovi and A. andreniformis and A. florea. Significant differences were found in the distribution and variability of the number of hamuli between species (populations). The mean numbers of hamuli for A. andreniformis differed from those of A. florea. Both these population means differed from those of A. cerana, A. koschevnikovi and A. m. intermissa. No significant differences were found between A. cerana and A. koschevnikovi. When the analysis included data for A. dorsata, A. nigrocincta, A. m. carnica, A. m. caucasica and A. m. ligustica, the results showed significant differences in hamuli numbers between A. andreniformis/A. florea and A. cerana/A. koschevnikovi/A. nigrocincta and A. m. intermissa/A. m. carnica/A. m. caucasica/A. m. ligustica. Hamuli numbers in A. dorsata significantly differed from those of other populations except A. m. intermissa. These results show that hamuli numbers are useful in the classification of honeybee populations. Whether hamuli would be useful in multivariate analysis depends on the correlation between the number of hamuli and the other characters used.

  • Description: Ice-free regions in Antarctica provide natural laboratories for investigating and modelling change in landscapes and ecosystems. The terrestrial ecosystems in western Dronning Maud Land are potentially critical to improve current understanding of polar ecosystems, however, they remain poorly represented and under-protected. Lichen habitats were used to elucidate geomorphic-biological feedbacks that shape the landscape’s topography and biodiversity, which in turn promote environmental heterogeneity. Environmental parameters acting on two landforms were measured to determine the colonisation and growth of lichens in niche habitats. The habitats were identified and characterised, and topographic heterogeneity was found to control lichen colonisation. Micro-topographical niches provide the most stable environments for colonisation, and are preferred habitats. Lichen-habitat interactions were species specific, and closely related to insolation and moisture availability. The bidirectional relationships between rock weathering and lichen colonisation was ascertained. Results showed that lichens are good indicators of landform heterogeneity, but also promote landform heterogeneity. Given the habitat preferences of specific lichen species, they provide proxy to evaluating environmental responses, especially environmental change. The findings of this research are to be used as baseline data for future studies exploring ecosystem development in emerging landforms.

  • Description: The aim of this thesis is to provide a differentiated view of peri-urban agriculture in the context of urban population growth in Asmara, Eritrea. Peri-urban agriculture is viewed as a distinct type of broader urban agriculture, and in this case is not as subsistence-orientated as other branches of it. Urban population growth is comprised of three elements, namely, natural population increase, rural-urban migration and outward movement of people to the urban periphery linked to urban expansion. Each receives extensive treatment. Asmara is the capital city of Eritrea and using Weeks (2004:473) phrase can be termed as a “primate city”. As such, it exerts a major influence on the political, economic and cultural life of the country, but has never been subjected to this type of research. The analytical framework that is adopted is that of urban population growth. In order to operationalize it, theoretical insights into each of its three branches were applied. For example, the informalisation of the economy in developing cities was used to explain the operation of peri-urban agriculture in the context of natural population growth. An adaption of the original Harris-Todaro Model by Fields (2004) was used for the migrants, and the Mosaic Model by Bryant and Johnson (1992) for those facing urban encroachment. Primary data were collected in the field by the author with the help of research assistants. This was supplemented by secondary data which involved reports commissioned by the Ministry of Agriculture and the Ministry of Public Works. Focus Group discussions were also held to supplement the data with information, views and insights that do not emerge in one-to-one interviews. This thesis demonstrates that those respondents operating within the context of natural population growth make a viable living from peri-urban agriculture, but that they also recognise that there are considerable challenges to be faced. Three sub-groups of farmers are identified. Of these, poultry farmers are the most vulnerable because of the high costs of the inputs, the uncertainty associated with avian „flu and an undeveloped distribution network. The vegetable producers, on the other hand, have a sophisticated marketing network, but low levels of education, high household numbers and an impending shortage of land and water. The agriculturalists that have migrated to Asmara seem to have created sustainable occupations for themselves over a number of years. However, 75 percent of them felt that migration to Asmara was not worthwhile. This negative view is explained in terms of the struggle it has taken to maintain such a living and the growing shortage of land. This set of farmers achieves lower production levels than its city-reared counterparts, carries considerable expenses and has to hire its land. The farmers who have had to cope with urban encroachment fall into two classes. The first has chosen to remain in peri-urban agriculture despite feeling the pressure to scale down activities and thus have a lower income. The majority of this group are dairy farmers who have to trade off increasing costs of cattle feed against shrinking grazing land. They are unwilling to take the initiative to solve their land problems, but look to the authorities to do so. The second class of respondents in this category have abandoned their agricultural holdings. The majority of these agriculturalists are poultry farmers living in the Eastern side of the city. A shortage of agricultural land, high population densities and high costs of inputs make poultry farming difficult. This thesis, therefore, presents a multifaceted view of peri-urban agriculture. While each set of farmers has to cope with its own particular circumstances, there is a common factor. This is the tension between preserving agricultural land on the urban fringe and the need to expand the city to accommodate its inhabitants.

  • Description: South Africa is one of the countries hardest hit with the Human Immunodeficiency Virus (HIV) and Acquired Immuno Deficiency Syndrome (AIDS) epidemic. In response to the epidemic, the South African government adopted the Comprehensive HIV & AIDS Care, Management and Treatment programme strategic plan (CCMT) in 2000 (1) and developed the Operational Plan for CCMT for antiretroviral therapy rollout in 2003 (2). In order to monitor the progress of the implementation of CCMT, the National Department of Health (NDOH) adopted the Monitoring and Evaluation (M & E) framework in 2004 (3). The aim of this study was to assess the HIV & AIDS programme in Grahamstown‘s public sector health care system by using the national M & E indicators of the HIV & AIDS programme. The national M & E framework was used as the data collection tool and available information was collected from various sources such as the District Health Office (DHO), Primary Health Care (PHC) office, accredited antiretroviral sites and the provincial pharmaceutical depot. Group interviews were conducted with key stakeholder health care professionals at the District Health Office, Primary Health Care office, Settlers Hospital and the provincial Department of Health personnel. A one-on-one interview was conducted with the Deputy Director of HIV & AIDS Directorate, monitoring and evaluation in the National Department of Health. Available indicators such as budget and expenditure including antiretroviral procurement; human resources; nutrition-related indicators; prevention care and treatment indicators were collected. A group interview was conducted to document current practices, or where there was a lack of documentation, for indicators such as traditional medicines and pharmacovigilance. Most of the national M & E indicators are not required to be collected or collated by the district because the reporting format designed by the provincial Department of Health is different. Facilities, districts and provinces in South Africa are at different levels of implementation of the antiretroviral programme and hence a common format of the M & E indicators is not used by all provinces. Uniform data collection is not achieved due to human resources‘ constraints and other challenges such as continued use of manual reporting systems by the clinics. Districts are expected to report according to the formats drawn up by the provincial Department of Health (DOH) and there is a lack of awareness regarding the national M & E document amongst the Grahamstown Health Care Professionals. There is a need for training on the use of the M & E national framework so that the HCPs at the primary and secondary levels of the health care system are proficient with the process of M & E, and can provide inputs as well as take ownership of the process. The establishment of an M & E unit in Grahamstown is essential so that data collection and submission of the HIV & AIDS programme in the public sector according to the National M & E framework is addressed. However, despite all constraints and challenges in the public sector health care system in Grahamstown, available human and financial resources are being used effectively to maintain the HIV & AIDS programme.

  • Description: The study sought to evaluate the extent to which poverty alleviation programmes of the Eastern Cape Provincial Department of Rural Development and Agrarian Reform (DRDAR) addressed the agricultural needs of the Ndakana community. The emphasis had been on the effectiveness with which these programmes were implemented. Ndakana Village is situated in the Nqamakwe District. The village consists of Hili-hili, Mathafeni, Ncora and Diphini locations which are approximately twenty kilometres from the rural town of Nqamakwe in Amathole District. In the Eastern Cape, several poverty alleviation programmes are implemented which should, inter alia, alleviate the phenomenon of poverty in the rural areas. Despite these programmes it, however, appears that there is very little, if any, improvement in the poverty situation. Against this background it is essential that the progress in the alleviation of poverty be evaluated and if necessary, steps be taken to ensure that the envisaged objectives be achieved. On the importance of evaluating the program, Monette et al. (2011:5) write that in the past few decades, many large, ambitious expensive programmes intended to cope with social problems and to provide services to individuals have been developed. Along with the growth of these programs has emerged an increasing concern over their results: Do they achieve their intended goals? These programs are costly, and some evaluation is needed to assess whether resources are, indeed, being used effectively. Equally important, a program that fails to achieve its goals leave a problem unresolved or a service undelivered. Monette et al. (2011:6) further regard evaluation as a use of scientific research techniques to assess the result of a program and evaluate whether the program, as currently designed, achieve its stated goals In accordance with the Reconstruction and Development Programme (RDP) (1994:20), a national land reform programme is the central driving force of rural development. Such a programme aims to effectively address the injustices of the forced removals and the historical denial of access to land. The RDP aims to ensure security of tenure for rural dwellers in implementing the national land reform programme, and through the provision of support services, the South African government intends to build the economy by generating large-scale employment, increasing rural income and endeavours to eliminate overcrowding.

  • Description: The use of mobile phones and other mobile devices are becoming widespread and almost all of these mobile devices have some sort of mobile Internet access. Due to the increase in mobile Internet usage, many websites need altering in order to become mobile compatible. Creating a mobile compatible version of a website is challenging due to formatting and capability restrictions imposed by the mobile device. Currently, one of the popular methods of creating a mobile compatible website involves the creation of a new, dedicated mobile version of the website. However, this approach can prove to be expensive, and repetitive, since a fully functional desktop version of the website often already exists. A second method involves the use of a transformation proxy to transform the traditional website into a mobile compatible version. This research develops a transformation framework that enables a web developer to create a single set of source files that can be used to render output compatible with both traditional and mobile devices. In developing this framework, capabilities and restrictions of the mobile device were examined. Furthermore, current mobile web development guidelines and best practices were discussed. This resulted in the development of a method to identify and outline areas of a traditional website for transformation into a mobile friendly format. Furthermore, a transformation engine that allowed processing of the traditional website into a mobile compatible website was developed. This transformation engine extracted the outlined areas, and rendered the extracted content, all while maintaining the website’s original functionality. The development of a prototype verified that the transformation concepts are valid, and provided for the development of guidelines and recommendations. The development of a framework to enable the web developer to create a website once, and enable it to adapt its output for mobile devices, will have a positive impact on the development of content for the mobile web.

  • Description: The nonlinear absorption properties of 6 mono-substituted and 3 symmetric zinc phthalocyanine complexes have been studied in dimethylsulfoxide (DMSO) using 10 ns pulses at 532 nm. The non linear absorption of the complexes has been studied using the Z-scan technique. The study showed that both the singlet and triplet excited states contribute to the non linear absorption behavior. The nonlinear third-order susceptibility and second-order hyperpolarizability values of the complexes are reported. It was observed that two of the symmetric phthalocyanine complexes (5-α substituted with aminophenoxy and 9-β substituted with carboxyphenoxy) showed better and promising optical nonlinearity when compared to the other complexes studied.

  • Description: The objective of the study was to determine perceptions of rural consumers on mutton quality, and the quality of mutton at purchase points in the Eastern Cape Province, South Africa. The study was conducted in five different municipalities (Buffalo City, Nkonkobe, Ngqushwa, Lukhanje and Amahlathi). A survey was conducted where a sample of 215 consumers were randomly selected and interviewed, either at point of purchase or as they left the shops. The survey was not limited to the shoppers only but also extended to households from the villages. Questions on some of the most important meat quality cues were compiled. The physico-chemical quality of mutton purchased from different shops was also determined. Forty different shops and butcheries selling mutton from all the selected municipalities were visited. Different parts of mutton samples were bought. Physico-chemical qualities of mutton such as colour (L* - lightness, b* - redness and a* - yellowness) and meat pH measurements were taken at points of purchase. Cooking loss and tenderness evaluations were later done at the Meat Science laboratory at the University of Fort Hare. The results indicated that price was one of the major factors affecting the purchasing decisions of consumers. Thirty four percent of the consumers preferred mutton as compared to other protein sources, even though they were not buying this type of meat because it was not affordable to them. Both male and female consumers suggested that more sheep farmers need to be established in order to reduce the levels of imported mutton into South Africa. They also highlighted that selection programmes that will result in efficient sheep production and reduced mutton prices need to be implemented. Meat at points of purchase was affected by season resulting in lower lightness (L*24.7±0.49) values in winter and higher (L* 32.2±0.49) in Spring. The class of shop did not have an effect on meat quality attributes. Trotter had high values of lightness (L*30.4±2.78a), redness (a*30.4±2.78a), yellowness (13.1±1.08a), pH (6.3±0.12a), tenderness (24.9±3.69b) and cooking loss (39.5±4.38ab). The number of days from when the meat was put on the shelves to the time when it was purchased for consumption (days to purchase) had a significant (P<0.05) negative correlation with the Warner Braztler Shear Force (WBSF)values and lightness of the meat. Significant negative (P < 0.05) correlations between pH and colour of the meat (L*, a* and b*) were also observed. It was concluded that rural consumers perceive the quality of mutton as the best and that the physico-chemical quality of meat purchased from different shops was different, largely based on the part of meat, meat storage conditions and not necessarily on the class of the shop.

  • Description: From introduction: A popular misconception regarding Aristotle's views on modality is that Aristotle adhered to the doctrine of no unrealized possibilities. According to this doctrine, all possibilities are realized in time; in other words, if it is possible that something could happen, then at some time it is the case that that happens. For example, if it is possible for Socrates to escape from prison, then there will be a time at which Socrates will actually escape from prison. On this view, the possible and the actual co-incide; whereas there is abundant evidence that Aristotle was careful to maintain a distinction between the possible and the actual.
