The critical essay gained immense popularity in the sixties and seventies in the Maghrib as a way to depict national realities that had failed to live up to nationalist ideals. Their authors often shared similar attributes: young highly educated intellectuals, committed toward modernity and who steered clear of politics. Such was the case of Abdallah Laroui (born 1933) and Hichem Djaït (born 1935), two celebrated Maghribi thinkers of the post-1967 generation in Arab thought. Despite their different ideological positions, they share a similar trajectory and both wrote about the need for another Arab renaissance, in Laroui's La crise des intellectuels arabes (1974) and Djaït's La personnalité arabo-islamique (1974). The turn to critical writing is routinely dismissed for being secondary, for having a restricted audience and little political impact, yet it highlights well the Maghribi postcolonial intellectual's competing demands: to conform to an ideal representation of intellectual "commitment" through critical speech, and to secure national recognition and integration. As such, this thesis confronts the often-neglected impact of nationalism on intellectual conducts after independence around the impact of their disillusionment, and forces us to rethink critically notions of engagement, the role of intellectuals and postcolonial cultural productions that are current in Middle East studies, and problematically envisaged by postcolonial studies. These texts have been approached as dynamic objects responding to a set of questions in their time, to account for the materiality of thought production, mobilising David Scott's concept of the "problem-space of intellectual production" (1999). This thesis looks at Abdallah Laroui and Hichem Djaït's intellectual projects from 1965 to 1978, to study the genesis and aftermaths of their critical moment, focusing on their published writings (critical essays and academic studies), press and journal articles, interviews, and fictional texts from a later period, in Arabic and French. Their writings will be read alongside several cultural journals, newspapers and memoirs dealing with this period of the Maghrib's history to account for the processes of circulation and reception by relevant audiences.

The aim of this study was to explore how the newly acquired democratic dispensation in South Africa has affected the lives of secondary school learners. A literature review was undertaken on democracy, democratic citizenship and democratic government. An empirical investigation using a qualitative phenomenological approach examined the situation of secondary school learners using the various agencies of citizenship, namely the family, peer groups, the school and the community. Data was gathered by focus group interviews. It emerged from the examination of the collected data that democratic citizenship has improved the situation of secondary school learners regarding their interpersonal relationships with their families, peer groups, school-mates and other members of the community at large. However, the findings indicated that the democratic dispensation has not yet had a significant impact on the situation of secondary school learners at school and in their communities. / Educational Studies / M.Ed.

This essay is divided roughly into two main sections; in the first I have discussed the Tswana as a whole, their environment, their origins and their more recent history. In addition to this, I have tried to give a clear picture of their tribal political structure and economic activities, as well as their domestic activities, all of which are integrally linked to the kind of house form adopted by the Tswana. The last, and most important, part of the first section is a presentation of some of the earliest written descriptions of Tswana dwellings made by the first white travellers to enter Tswana territory. The second section takes the form of a presentation of findings observed during the course of personal field research undertaken in the Tshidi-Rolong village outside Mafikeng. This research was done by means of a number of questionnaires drawn up by myself and filled in on the spot with information supplied by house owners and sometimes the builders themselves. This survey was carried out largely at random, with several of the houses chosen arbitrarily because of an interesting feature which set them apart from other dwellings. This written information is backed up by a large bulk of visual information in the form of photographs taken personally, both of the dwellings in general, and of details of the houses. Although this essay may appear to be rather fragmented, my aim is to give a graphic account of changes in Tswana dwellings by comparing features of contemporary dwellings with those observed in the early nineteenth century. The fact that among the Tswana , the building style of one sub-tribe may vary slightly from that of another subtribe, has not affected my study to any large extent , since I was fortunate enough to have done my field research among a branch of one of the original groups, namely the Rolong, whose houses, along with those of the Tlhaping, were the first to be documented. Therefore, most of the differences which have occurred between the dwellings of the contemporary Tshidi-Rolong and those from the early nineteenth century are a direct result of the process of westernisation.

A study of petrological and geochemical variations through the upper Critical Zone of the Bushveld Complex at Amandelbult section of R.P,M. was undertaken. The sequence at this locality may be divided into seven "units" two of which appear to be complete, possessing the sequence harzburgite-pyroxenite-norite-anorthosite. The other five Units lack basal, intermediate or upper members. Considerable lateral variations are apparent in this sequence, but these are restricted to the Lower Pseudo Reef-Merensky Reef interval, tne same portion of the succession which is affected by pothole structures. The single most important petrographic feature of genetic significance is the occurrence of annealed, recrystallized anorthosite immediately underlying ulstramafic layers. This, together with the undulatory nature of the contact between the two rock layers, suggests that the ultramafic layer was emplaced as a hot liquid over a pre-existing, crystalline anorthosite floor, and that some remelting of this layer occurred. Variations in the chemical make-up of constituent silicate minerals reveal a number of significant processes which may have been operative in the magma chamber prior to crystallization, Olivine grains, for instance, exhibit extremely wide chemical variations both within single layers and from one layer to the next. These variations are best explained by re-equilibration processes with spinel and base metal sulphides, rather than by wide variations in original liquidus compositions. It appears that the compositions of the initial liquids from which each basal olivine-bearing layer crystallized, were approximately similar. Variations in the iron-magnesium ratio of ortho-pyroxenes indicate well defined continuous fractionation trends in units which are considered to be complete. Magnesian compositions are recorded in ultramfic members, while increasingly iron-enriched values are recorded upwards through the sequence pyroxenite-norite-antorthosite. Plagioclase grains exhibit less well defined fractionation trends, but it is clear that an upward increase in An is encountered through indivitual Units. This is in direct contrast to the trend exhibited by orthopyroxene. A further feature of plagioclase grains is the considerable degree of chemical zonation exhibited by them. In cumulus grains this is commonly manifested as strongly reversed rims, while in intercululus grains normal zoning is ubiquitous. Whole-rock chemical variations through the succession indicate that cyclical variations occur through successive Units, but that these merely reflect changes in modal mineralogy and not liquid fractionation trends. Such trends can be shown for selected element ratios, where these elements are known to partition into a single mineral phase. Rations of pyroxene components such as the nickel/scandium ratio, exhibit a saw tooth pattern through successive Units, while ratios of plagioclase components such as the strontium/alumina ratio have unique, fairly constant values for each individual Unit but different values for successive Units. The latter type of cyclicity is not always strictly confined to lithologically recognized boundaries between Units, and a slight overlap into overlying ultramafic layers is apparent. An investigation of variations in trace element levels in a single layer in five widely separated boreholes revealed that there is some evidence for a lateral fractionation trend from the southwest (more primitive) to the northeast (more evolved), although the small number of data points available preclude definite conclusions. There exists in the data some evidence that the Giant Mottled Anorthosite differs chemically from the other anorthosites in the study section, and that it more closely resembles rocks of the Main Zone. This evidence is particularly apparent in variations of the chromium/aluminium ratio of orthoyroxene grains, and in the An content of plagioclase grains, both of whose trends exhibit distinct inflections at the base of this member. The features of the succession at Amandelbult are best explained by the model of Eales et al. (in press, a), which visualizes the input of a number of pulses of new, hot liquid into a magma chamber containing the fractionated residua of previous influxes. At a critical point in time, just prior to the mafic Merensky Reef input, a large input of gabboic liquid was intruded at high levels in the chamber. The lower portions of this liquid mixed with the residua of earlier mafic inputs, which in turn mixed with new inputs of mafic, typical Critical Zone liquids. Thus the lower portions of the study section represent mixtures of new Critical Zone liquids with the residua of previous such influxes, while the upper portions have the added complication of mixture with a Main Zone-type liquid. The unique chemical character of the Giant Mottled Anorthosite appears to be a direct manifestation of the influence of the Main Zone liquid. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plug-in

One of the most remarkable features of the layered sequence of the Bushveld Complex is its lateral consistency in lithology. This work has established a geochemical and lithological correlation along 170 km of strike of the interval between the UG2 chromitite and the Merensky Reef within the Upper Critical zone of the western limb of the Bushveld Complex. The correlation is based on geochemical investigations of 10 borehole intersections and lithological comparisons of more than 20 borehole intersections around the western lobe of the complex. The basic data presented include 123 whole-rock analyses for major and 12 trace elements, 97 analyses for ' 12 trace elements, and ca. 5500 microprobe analyses of all major phases. Patterns of cryptic variation are established. Some layers (the UG2 chromitite and pyroxenite) show considerable consistency with regard to geochemistry and lithology. Others can be traced along most of the investigated strike length, such as the Lone Chrome Seam, the Footwall Marker anorthosite and the immediate anorthosite footwall to the Merensky Unit. Most of the distinguishable members within the study section, however, show great variation along strike (i.e., the Lower and Upper Pseudoreef Markers, the central noritic sequence in the southern arm of the western limb and parts of the immediate Merensky Reef footwall succession). Several models have been evaluated to interpret the geochemical and lithological data. The author comes to the conclusion that the degree of lithological consistency depends on the variability of magmatic parameters within different parts of the chamber. The most important of these parameters are: (i) the size of fresh primitive influxes and consequently the heat flux, (ii) the composition of the residual liquid, and (iii) the frequency of the influxes. Fresh influxes of more or less similar composition thus spread out along the floor if the residual liquid was less dense than the fresh primitive liquid, but intruded the chamber as a plume where plagioclase had crystallized for some time and the residual liquid had become relatively dense. The size of the influx may be regarded as a measure of the amount of heat flux from the feeder into the chamber. A large influx created uniform physicochemical conditions in the chamber whereas a smaller influx created a strong lateral gradient of physicochemical parameters in the chamber, with subsequent differences in viscosity, density, convection currents, yield strength and thus different mixing behaviour of different liquids. Furthermore, a persistent heat flux from the feeder may have delayed crystallization of successive phases in those parts of the chamber proximal to the feeder . Therefore, new influxes would have been deposited on a footwall of varying thickness and lithology in response to different degrees of crystallization and accumulation along strike. The development of a normal cyclic unit (chromititeharzburgite-pyroxenite-norite (+anorthosite?)) may thus have been interrupted at various stages in different parts of the chamber. The ability to correlate anorthosites over great strike distances implies that their formation did not follow entirely random processes but was dependent on specific magmatic conditions which prevailed over laterally extensive portions of the chamber at certain stages during the evolution of the crystallizing liquid.

Tribal (rural) communities possess assets/resources that can be utilised in improving the quality of life of their residents. The processes involved in the usage of these assets toward community-led development can determine the success or failure of the development efforts by the community. The research conducted was aimed at investigating the processes involved in utilising these assets, with reference being placed on two community-led development approaches namely Asset Based Community Development and Sustainable Livelihood Framework. The research will examine the processes that the Royal Bafokeng Nation has used in the successful development of its community. A comparison of the community-led development processes will be compared to the Integrated Sustainable Development Strategy formulated by the South African government to develop rural communities. The results indicate that development is not just about asset identification, it‟s more complex than that. If development was just about resource identification then a lot of tribal communities would be developed. Development is about the interactions between leaders, community and external sources and in the case of RBN, administration as well. It is about interaction between leaders and community in the form of participation in development efforts; interaction between leaders (and administration) with external sources such as municipalities to enhance development; and interaction between community and external sources through social capital. The results also indicate that whilst it is the duty of government to provide basic services, communities can partake in other development initiatives. That development in it‟s entirely should not be left to government if communities have the means of initiating development. That government has to improve certain aspects in their development strategies, but that it has made strides in formulating strategies to develop rural communities. The challenges for government come in the implementation of these strategies. That partnership between community and government can lead to better and sustainable development initiatives.

D.Ed. / The purpose of this inquiry was to explore perceptions and practices of family well-being in the context of child-headed families, and to propose a comprehensive framework that would be beneficial for supportive, educational interventions in the families. This inquiry was conducted among orphans living in two child-headed families. Family life of the orphans was the major focus of this study. All the resources from within a family, the activities, interactions and the way a family organizes and plans determines the well-being of individuals in the family. The specific characteristic of this inquiry is that it captures phenomena around human group way of life (families) and human conduct (lived experiences, interactions and behaviours). It is for this reason that the qualitative ethnographic design was employed and a Grounded Theory Approach of analysis was used to inductively derive a comprehensive framework for the facilitation of well-being in the child-headed families who participated in this study. Data generation was done through in-depth interviews, small group discussions, visual and imagery observation, and theoretical sampling. Interviews were conducted with orphans 12 years and older and for orphans under the age of 12 years observations were employed for ethical compliance. The grounded theory analysis included initial coding, focused coding, axial coding, identifying main categories and memo writing to develop the framework.
