Full textAbstract:
This essay examines how the factors that inspire Tambudzai and Nyasha to counter the patriarchy are portrayed and how these factors contribute to the formation of hybrid identities among the younger generation of women in Nervous Conditions (1988) by Tsitsi Dangarembga. Both characters are faced with different predicaments which makes it necessary to divide the factors in regard to each character. The factors that are connected to Tambudzai are the following: the death of Nhamo, the patriarchal male figures, and the will to obtain an education. Meanwhile, the factors that are connected to Nyasha are the relationship with her patriarchal father, the desire for liberation and gender equality. Postcolonial and feminist criticism are applied. The main focus of the essay is hybridity, or double identity, where the specific term cultural hybridity is used in order to analyze the effect that the struggle against the patriarchy has had on Tambudzai's and Nyasha's emerging hybrid identities. The feminist-psychoanalytic approach is used to analyze the factors that inspire Tambudzai and Nyasha to counter the patriarchy. The results show that the factors that inspire Tambudzai and Nyasha to counter the patriarchy have been visible and crucial to the formation of their hybrid identities. The struggle that Tambudzai and Nyasha have to face when going against the patriarchal system brings certain predicaments in their lives that affect them and their identity tremendously. One of these predicaments is the realization that patriarchy is universan and, hence, something you cannot escape.

Full textAbstract:
Diplotaxodon limnothrissa Turner (1995) is a widely distributed species occurring throughout Lake Malawi, extending from the surface to a depth of at least 220m. It is probably the most abundant cichlid in the lake with biomass estimates of around 87 000 tonnes in the pelagic zone alone. The species is exploited commercially in the southern part of the lake but since its inception the fishery has never been assessed. As such this study investigates some aspects of age and growth of the species besides applying a yield-per-recruit analysis to assess the status of the fishery. Analysis of sectioned sagittal otoliths revealed that D. limnothrissa is fast growing and relatively long-lived species, attaining ages in excess of 10 years. Growth in length was rapid in immature fish, with fish attaining almost half of their maximum size within their first year. Le ngth-at-age was described by the von Bertalanffy growth model with combined-sex growth described as Lt = 211.21(1-exp(- 0.24(t+1.36))) mm TL. Total, natural and fishing mortalities were estimated at 0.76 yr⁻¹, 0.31 yr⁻¹ and 0.45 yr⁻¹ respectively. Per-recruit analysis indicated that the D. limnothrissa stock in the southeast arm of the lake is fully exploited as indicated by the current spawner biomass-per-recruit ratios of 31-55% (SB/R)F=0. Modelling indicated that the current age-at-capture (2.67 years) is lower than the age at which yield is optimised (> 5 years) based on the F₀·₁ harvesting strategy. It is, therefore, recommended that the age-at-capture should be increased from 2.67 to 5 years to optimise yield.

Full textAbstract:
Behaviour and space utilisation of rock-dwelling cichlids were observed at Thumbi East Island, Lake Malawi. 1. Males of five species of the mbuna complex held long-term territories. Pseudotropheus elongatus "aggressive" vigorously defended a feeding area and sometimes a spawning site interspecifically, but did not feed in the peripheral part of their territory. Spawning sites of Pseudotropheus zebra, Pseudotropheus tropheops "orange chest", Labeotropheus fuelleborni, and Petrotilapia nigra were interspecifically-defended, while larger mating territories were defended against conspecific neighbours. Feeding areas were shared with many fish and often extended beyond the defended area. There was considerable variation in behaviour and space use within and between species and between times of day. 2. Non-territorial P. zebra used larger ranges than territorial conspecifics, and fed more on plankton, but individuals had preferred benthic feeding areas, often in conspecific territories. These 'floaters' were often aggressive. Both size and relative brightness independently predicted the outcome of aggressive interactions between floaters, and a site-specific dominance hierarchy was suggested, with some individuals appearing to be semi-territorial. 3. Males and females of 21 and 13 species respectively were found to establish temporary breeding territories. Overall breeding seasonality was bimodal, but reproductive timing and territory characteristics differed among species. Temporary territories had a considerable impact on the behaviour and habitat use of all resident mbuna species, even causing abandonment of territories. 4. Non-breeding Protomelas taeniolatus had limited home ranges, and showed little aggression. During the highly-synchronised reproductive season, males defended spawning sites and females fry-guarding territories. Most chases were directed towards the commonest fish, but predators were chased further and faster. Female behaviour changed over the guarding period. Females generally continued territorial defence after the brood had disappeared. Most broods contained fry of different sizes and species. Significant benefits were found for guarding females with clustered territories, but females did not appear to choose sites adjacent to conspecific parental females. 5. Territoriality in fish is taxonomically widespread and may serve several functions according to species, sex and developmental stage. It also varies according to genotype- and phenotype-limited strategies and short term costs and benefits. Territories may be simultaneously multifunctional.

Full textAbstract:
More than twenty years ago, over twenty species of the rock-dwelling cichlid species (Mbuna) were translocated from the northern Lake Malawi, where they are endemic, to Thumbi West Island, Lake Malawi National Park, in the southern part of Lake Malawi. Among these species, Cynotilapia afra, Pseudotropheus callainos and Pseudotropheus tropheops 'red cheek' are strongly territorial, and have increased substantially in number and are widely distributed, particularly in the three to seven metre depth band of the rocky habitats at the Island of Thumbi West. It is feared that the increase in population density of translocated species (hereafter referred to as introduced species) may be at the expense of ecologically equivalent native species which could be eliminated. In this thesis the following key hypotheses have been tested: (i) that the introduced species having originated from a region of Lake Malawi which is generally poor in nutrients and introduced in an area which is richer in nutrients, would cope better than the native species during periods of nutrient scarcity which occur frequently, often seasonally in oligotrophic lakes, such as Lake Malawi; (ii) that the introduced species are fitter than their ecologically equivalent native species in the acquisition of territorial space in which they breed, feed and seek shelter, and (iii) that introduced and native species coexist by utilizing different microhabitats. Results show that: 1. the introduced species, P. callainos and P. tropheops 'red cheek' may have responded positively to enhanced nutrient availability, as they were found to have better condition factors and fecundity indices at Thumbi West Island than at sites of their origin, in the northern lake Malawi. Cynotilapia afra, P. callainos and P. tropheops 'red cheek' also maximise their life-span fecundity by starting to reproduce at relatively smaller size than the native species with which they overlap in microhabitat requirements. Similarly, their breeding peaks precede the breeding peaks of the native species with which they overlap in microhabitat requirements. Consequently, due to priority residence effects, the offspring of introduced species may have a competitive edge in the use of essential resources, e.g., refuge over the offspring of the native species whose peak-recruitment occurs later in the year. 2. There is an overlap between the introduced and native species in their microhabitat requirements. Consequently, interference competition between them for territorial sites occurs. The choice of optimal territory sites is constrained by the fact that females preferentially mate with males that defend significantly smaller holes, or crevices among the rocks, probably as a means of minimizing egg predation during spawning. 3. The population of territorial males of introduced species seems to grow exponentially, depending on the availability of suitable microhabitats, and an equilibrium between them and males of the native species may be reached. Competition for optimal territory sites seems to intensify, once the carrying capacity in a particular area has been reached, and it is at this stage that some territorial males of the introduced and native species with similar microhabitat requirements, e.g., C. afra and P. zebra, or P. tropheops 'red cheek' and its sibling native species, P. tropheops 'orange chest' displace each other. However, it seems unlikely that any of the native species which were compared with the introduced species would be driven to extinction because: (a) there is a considerable interspecific territory turn-over between the introduced and native species that overlap in microhabitat requirements. (b) Even in situations where some of the native species occur in microhabitats that are not of their preference, they occupy patches of suitable sites and are capable of breeding. (c) It has been suggested that since introduced and native species breed throughout the year and are polygamous and have intraspecifically shared paternity, they are capable of fertilizing many gravid females of their own species. Therefore, the population of native species may not be detrimentally limited by the presence of introduced species. (d) The introduced and native Mbuna species that prefer small rocks coexist in the same microhabitats, partly by feeding at different sites with different intensity and they also feed at different heights in the water column. 4. The following studies have been recommended before any management intervention, such as culling is adopted: (i). interaction between the introduced and native species in the shallow and deep rocky habitats; (ii) space utilization and survivorship of juveniles of the introduced and native species; (iii) laboratory studies to confirm the role of different nutrient regimes on the fecundity of Mbuna; (iv) the possibility of hybridization between the introduced and native species; (v) monitoring of population growth and distribution of the introduced species around Thumbi West Island should continue in order to detect their long-term effects on the native species.

Au total, nous avons découvert cinq sites : Mougoutsi, Dilangui 1, Dilangui 2, Mavoundi 5 et Mavoundi 6. L' ensemble des sites a livré une diversité d'outils. Tous les outils ont été ramassés en surface. L'étude des sites et du matériel a montré de nombreuses similitudes avec d'autres sites du Gabon et de l' Afrique centrale. En effet, il y a de fortes similarités du point de vue de la nature des sites d'une part, et de la typologie du matériel récolté. Aussi, l'étude typologique des objets lithiques de Tchibanga, en l'absence de fouilles nous permettent de penser que la préhistoire de Tchibanga présente des ressemblances avec des industries sangoennes mais aussi lupembo-tshitoliennes rencontrées ailleurs au Gabon.

Full textAbstract:
The nominal species Petrotilapia tridentiger Trewavas, a rock-frequenting fish from Lake Malawi, occurs in three distinct male and female colour forms at Monkey Bay. Field observations on courtship and aggression indicate that the three colour forms are distinct species. The taxonomy of the three species of Petrotilapia that occur at Monkey Bay is revised. R. tridentiger is redescribed and two new species, P. genalutea and P. nigra, are described. The three species are very similar morphologically and are considered to be sibling species. The only morphological character which reliably separates the three sibling species is live coloration: Live coloration is considered to be an important component of the specific mate recognition systems in Petrotilapia species. The coloration of a further fourteen forms of Petrotilapia is described and it is suggested that these forms are valid species. Space resource partitioning plays an important role in facilitating the coexistence of Petrotilapia sibling species. Space is partially partitioned in terms of depth range. In shallow water, where all three species are sympatric, there are differences in the feeding sites used by the various Petrotilapia forms. Changes in niche breadth and overlap, which are associated with changes in the abundance of epilithic algae, indicate that competition for feeding space occurs between the three Petrotilapia species. The Petrotilapia species partition their resources according to a social dominance hierarchy. Dominant forms, such as territorial males, R. tridentiger females and schooling R. genalutea females, have access to rich food supplies which occur within the territories of certain highly aggressive Pseudotronheus species. are facultative and opportunistic .feeders. Petrotilapia species Speciation in allopatry is considered to be the mechanism which adequately explains the current diversity of the genus Petrotilapia. The importance of an integrative approach to future systematic and ecological research on Lake Malawi cichlids is stressed.KMBT_363

Full textAbstract:
In Malawi, fish contribute about 60-80% to the country's animal protein supply. The greater proportion (> 50%) comes from Lake Malawi. Bathyclarias nyasensis and other clariid catfish contribute up to > 20% of the total catches. Catches of Bathyclarias nyasensis in the inshore area of the south-east arm of Lake Malawi are declining and a management plan for the fishery is essentially lacking. There is paucity of biological data that precludes the use of any option to manage the species. The principal aim of the thesis was to define the ecological role B. nyasensis, the most abundant and common of the Bathyclarias species. By examining life history characteristics within a food web context, it was hypothesized that the study would provide an insight into the interrelationships between species, and, hence form the basis for the development of a rational exploitation strategy for the species. The study was undertaken in the south-east arm of Lake Malawi (9° 30'S, 14° 30'S). The principal objectives of the study were to investigate the feeding ecology of B. nyasensis by examining morphological characters and structures associated with feeding, diet of B. nyasensis, food assimilated in the species using carbon (∂¹³C) isotope analysis, daily food consumption rate for B. nyasensis; and to relate the feeding ecology to life history traits such as age, growth, and some aspects of the reproductive biology of B. nyasensis. The suitability of sectioned pectoral spines and sagittal otoliths to age B. nyasensis was assessed. Due to reabsorption of growth zones with increasing spine lumen diameter with fish size, and the relatively low number of spines that could be aged reliably, only otoliths were used. The maximum age for B. nyasensis was estimated at 14 vears. Growth was best was described by the four parameter Schnute mc: lt ={42+(81¹·⁸ - 42¹·⁸)x1-e⁻°·°⁵⁽t⁻¹⁾}¹/¹·⁸ over 1-e⁻⁽⁻°·°⁵⁾⁽¹¹⁾ for female, lt={41+(98¹·² - 41¹·²)x 1-e⁻°·°²⁽t⁻¹⁾}¹/¹·² over 1-e⁻⁽⁻°·°²⁾⁽¹³⁾ and for male fish. Age-at-50% maturity for females and males were estimated at 7 years and 4 years, respectively. Typically, fish grew rapidly in the first year, but slower during subsequent years. Smaller fish were found inshore while larger fish were found in offshore regions. It was hypothesised that the rapid growth in the first year and slower growth later is a consequence of change in diet from high quality and abundant food source to a more dilute food and that this may be associated with a shift in habitat. Morphological characters associated with feeding were used to predict the food and feeding behaviour of B. nyasensis. The size of premaxillary, vomerine, pharyngeal dental and palatine teeth and premaxillary and vomerine tooth plates suggested the capability of B. nyasensis to handle both large and small prey, with a propensity towards smaller prey in composition to C. gariepinus. The molariform teeth on the vomerine tooth plate suggested that molluscs form part of the diet. The relative gut length (1.27±0.24) suggested omnivory, with an ability to switch between planktivory and piscivory. Buccal cavity volume and filtering area changed with fish size at 500-600 mm TL upon which it was hypothesised that the fish diet changed to planktivory at this size. Detailed diet analysis provided information upon which the above hypotheses could be accepted. Percent Index of Relative Importance (%IRI) and a multi-way contingency table analysis based on log-linear models were used to analyse diet data. Results showed that B. nyasensis is omnivorous, but with a distinct ontogenetic dietary shift from piscivory to zooplanktivory at 500 - 600 mm TL. The increased buccal cavity volume at the same fish size therefore, suggests that B. nyasensis is well adapted to filter the dilute zooplankton resource. Increased foraging costs of feeding on zooplankton explained the slower growth of larger fish. The dietary shift was finally corroborated by results of the ∂¹³C isotope analysis. A polynomial equation described the change in carbon ratios with fish size: ∂¹³C = - 33.188 + 0.4997L - 0.0045 (total length)² (r² = 0.598, n = 12, p=0.022). The ontogenetic shift in diet was synchronised with a habitat shift postulated in life history studies. In the inshore region, B. nyasensis were predominantly piscivorous (apex predators), and were zooplanktivorous in the offshore region, thereby forming part of the pelagic food web in the latter region. After examining "bottom-up" and trophic cascade theories, it was postulated that perturbations of the B. nyasensis stock would be discernible both at the top and lower trophic levels. As a piscivore and therefore apex predator, effects of overfishing B. nyasensis in the inshore region could cascade to unpredictable ecological changes in inshore areas and, due to the ontogenetic habitat shift, in the offshore regions. Examples of trophic cascade phenomena are provided. On the basis of the feeding study, it was possible to reconstruct the pelagic food web of Lake Malawi. Apart from the lakefly Chaoborus edulis, B. nyasensis is the other predator that preys heavily on zooplankton in the pelagic zone. Perturbations of the B. nyasensis stock could affect size composition of zooplankton which in tum, could affect production of C. edulis, a resource for the top predators in the food web. The findings of the present study contributed to the ongoing debate of introducing a zooplanktivore into the pelagic zone of Lake Malawi. Proponents for the introductions have argued that zooplankton predation by fish is inferior to that of C. edulis. Introduction of a clupeid zooplankton was proposed as a strategy to boost fish production in the lake. The zooplanktivore would either out-compete or prey on C. edulis to extinction. Opponents to this view argued that zooplankton biomass in the pelagic region was too low to support introductions and that the fish biomass in the pelagic region may have been underestimated. Results from the present study suggest that planktivorous fish (including B. nyasensis) might not be inferior to C. edulis in utilising the zooplankton resource; B. nyasensis is well adapted to utilise the dilute zooplankton resource, and by omitting B. nyasensis from previous studies, overall zooplankton predation by fish may have been underestimated by between 7 - 33%. On the basis of the theoretical migratory life history cycle of B. nyasensis, it is recommended that the current interest in increasing fishing effort in offshore areas should proceed with caution. Ecological changes that may have occurred in the inshore areas due to overfishing have probably not been noticed: as the offshore zone has never been fished. The latter zone may have acted as a stock refuge area. Higher fishing intensity in the offshore areas could lead to serious ecological imbalances and instability. The study has shown that life history characteristics studied in the context of the food web, and in the absence of other fisheries information and/or data, strongly advocates the precautionary principle to managing changes in exploitation patterns.

Full textAbstract:
The Masumbi Au-Cu deposit in the Ndori Greenstone Belt of western Kenya is hosted in dacitic volcanics of the Nyanzian Group (2710 ± 340 Ma) and dioritic to granodioritic felsic intrusives (2504 ± 48 Ma). The deposit is characterised by gold and copper mineralisation that is associated with quartz-sulphide veins and veinlets. The copper mineralisation typically occurs as chalcopyrite. Gold is closely associated with pyrite in mineralogy and its pathfinder elements silver, bismuth, tellurium and selenium in geochemistry. The gold occurs in two forms that may indicate two generations of precipitation: the equant and the elongate forms. Based on Au/Ag ratios, the equant gold grains can be classified as native gold as their gold content is greater than 90 wt%. The elongate gold grains can be classified as electrums as their silver content is greater than 38 wt%. While there is a strong Au-Ag association within individual gold grains supporting an orogenic model for the gold mineralisation, mineralisation at the Masumbi Prospect appears atypical of Archaean orogenic gold deposits because of the abundance of copper (up to 0.43%). The enrichment of silver, copper, bismuth and tellurium in ore assemblages is common in porphyry, VMS and epithermal systems, but their presence at Masumbi does not preclude the formation as an orogenic deposit. Assay results from three Masumbi diamond drill-holes show an apparent correlation between gold and copper. However, petrography and electron probe microanalyses results from this study indicate that chalcopyrite is an earlier phase than pyrite as it occasionally occurs as inclusions in pyrite. This petrogenetic relationship between pyrite and chalcopyrite suggests that there is no temporal relationship between gold and copper mineralisation. Statistical analysis of the assays shows no linear correlation between gold and copper thereby supporting the above findings. The gold and copper mineralisation have been interpreted as forming as two separate events with copper forming first followed by gold. These events are both related to the intrusion of the felsic rocks that are associated with the Aruan metamorphic event that has been responsible for the bulk of the gold mineralisation on the Tanzanian Craton. The common alteration assemblage in the Masumbi rocks comprises chlorite and epidote. This alteration assemblage is typical of regional greenschist metamorphic facies grading into amphibolite metamorphic facies in the Nyanzian Group of Kenya. However, these alteration minerals could possibly be products of propylitic alteration in the rock groundmass. Other alteration mineral assemblages, possibly of hydrothermal origin, comprise muscovite, sericite, quartz, carbonate, associated with the sulphides pyrite and chalcopyrite. Although the occurrence of gold appears to be controlled by the presence of pyrite, it is also associated with silicification. Exploration methods have been proposed to target undiscovered gold deposits in the Ndori Greenstone Belt that are similar to the Masumbi deposit. These methods could probably be applied to vein-type gold deposits in other granite-greenstone terranes in the Lake Victoria Goldfields.

Full textAbstract:
The intensive tank culture of ornamental mouthbrooding cichlids poses several problems which limit their aquaculture potential. This project addressed some of these problems for Aulonocara baenschi. The production of juveniles in 2501 aquaria was accelerated when: a) aquaria were equipped with refuges, b) females of less than 70mm in standard length were used as broodstock, c) mouthbrooding females were replaced with gravid females at seven day intervals, and d) embryos were removed from the mouths of females at replacement times for artificial incubation. Two sex ratios also accelerated juvenile production. The sex ratio (male:females) 1:30 yielded the highest spawning returns per tank, and therefore represented the most effective utilization of aquarium space (a critical consideration for the small-scale culturist). Contrastingly, the sex ratio 1:12 yielded the highest clutch sizes and a high percentage female spawning return, and therefore represented the most effective utilization of broodstock (an important consideration for culturists inhibited by financial constraints or having an abundance of culture vessels). The reproductive behaviour of A. baenschi was described. Emphasis was given to aspects of reproduction of relevance to culture, for example; spawning times and seasons, clutch size and its relationship with female size, age and size of sexes at first spawning, embryo development rate and size of first swimming juveniles. The slow growth rate of juveniles, combined with a late attainment of marketable size (± seven months) was a major limitation affecting the cuIture potential of A. baenschi. Two factors favouring the cuIture of this species was the high survival rate recorded for both adults and juveniles, and the comparatively high prices fetched by fish on domestic wholesale markets (R4,00 per fish). It is recommended that A. baenschi should not be cultured exclusively for the relatively small South African ornamental fish market. A more profitable strategy for domestic culturists should involve a major production effort with A. baenschi and other desirable species of Aulonocara (e.g . A. ethelwynnae; A. hansbaenschi; A. stuartgranti & A. maylandi) for foreign markets (in particular, the U.S.A.; Western Europe & Japan). Not only are these markets massive, but prevailing exchange rates of the Rand with these currencies favour such a strategy.

In 2000 the Centers for Disease Control and Prevention (CDC) in conjunction with CARE International began working with several local non-governmental organizations (NGOs) in the Nyanza Province of Kenya to reduce the rate of waterborne diseases. In 2002, CDC partnered up with the Society for Women and AIDS in Kenya (SWAK), a local NGO, to implement safe water treatment in SWAK-affiliated communities. SWAK is seeking ways to improve and expand sales of safe water treatment products in all of its communities. The water treatment sales expansion study has two components: · A technical component that addresses the most appropriate treatment · A business component that addresses marketing and sales of the products. This study focuses on the technical component. Its purpose is to evaluate the most appropriate water treatment in SWAK communities in the Nyanza Province. Three water treatment products were assessed - WaterGuard®, PuR®, and an alternative naturally occurring coagulant made of seeds from the Moringa tree. WaterGuard® is a chlorine- based disinfectant; PuR® is a coagulant and chlorine-based disinfectant. Both are already being marketed by SWAK. Moringa trees are indigenous to the region. Research was conducted in the United States and Kenya from October to April 2005. Field evaluation in Nyanza during January consisted of surveys that addressed water treatment practices, and water quality tests, specifically turbidity which interferes with the effectiveness of chlorine-based disinfection. Research revealed that rainwater is the best water source, and WaterGuard® is the best water treatment. PuR® was hardly used, and Moringa needs to be studied further for cost-efficiency and availability.
(cont.) A set of recommendations were drawn up and presented to SWAK communities, based on the results. These include promotion of rainwater treatment, retreatment of water every 24-48 hours, and health education programs.

Laine, Joy Elizabeth. "The concept of Self (ātman) in Nyāya-Vaiśeṣika philosophy." Thesis, Open University, 1990. http://oro.open.ac.uk/57309/.
Full textAbstract:
Nyāya, one of Hinduism's six orthodox schools of philosophy, has been of interest to western philosophers largely because of its sophisticated analysis of logical and linguistic problems. In India, the purpose of the orthodox school (or darśana - "view") has been to lead the student toward liberation (mokṣa). Hence Nyāya's preoccupation with logic should not in itself preclude a real concern with mokṣa. The broad aim of my thesis, therefore, is to determine how Nyāya functions as a complete darśana, to see if indeed the various aspects of the system stand together as a coherent mokṣamārga (way to release). Because Hindus conceive of salvation as the realization of a transcendental Self (ātman), and because the nature of such a Self has been a prime focus for Indian philosophical debate, this thesis will concentrate on the Nyāya understanding of ātman, and the logical arguments for its existence. Nyāya philosophers played a leading role in arguing against their Buddhist opponents in India who denied the existence of any such transcendental Self. The debate, which endured for many hundreds of years, culminated in the eleventh century A.D. with the works of Udayana, a leading Nyāya philosopher, and his Buddhist opponents, Jñānaśrīmitra and Ratnakīrti, after which time the Buddhist challenge waned in India, and the Nyāya school, known in its later phase as Navya-Nyāya, became more concerned with the method rather than the substance of the arguments. In this thesis I concentrate on one particular text of Udayana, the Ātmatattvaviveka (The Discrimination of the Reality of the Self), for in this text Udayana arranged most of the major disputes that had engaged Nyāya and Buddhist philosophers in the preceding centuries in such a way as to clearly display their relevance for the debate about ātman. The main body of my thesis consists of translations from this hitherto largely untranslated work, and discussions of some of the important arguments found therein. The concluding part of my thesis uses my findings for the broader discussion of the importance of ātman in Nyāya, and the place of Nyāya within the wider spectrum of Indian soteriological thought.

Thesis (MA)--Stellenbosch University, 2015ENGLISH ABSTRACT: Literature on public participation generally assumes the existence of a causal relationship between community participation in urban development programs and the satisfaction of beneficiaries of such programs with the outcomes of these development programs. In this study, the role played by public participation in fashioning perceptions of satisfaction or dissatisfaction of beneficiaries is investigated in the cases of two hostel redevelopment programs. The role of public participation is investigated by means of the Spectrum of Participation model of the International Association of Public Participation, a model which propagates a set of principles to be fulfilled before it may be said that beneficiaries have thoroughly participated in a program. Satisfaction or dissatisfaction of the beneficiaries is tested by means of the Hirschmann model of Voice, Exit and Loyalty, a model which hypothesizes that potential beneficiaries in a program - in order to express satisfaction or dissatisfaction with the process - may remain loyal to the program, may voice their dissatisfaction, or (as a last resort) may exit the program. After an analysis of the concept of public participation, this concept is applied-via interviews with samples of stakeholders and potential beneficiaries-to two different communities of interest: members of the Welcome Zenzile Housing Cooperative in Langa and the Ilinge LabaHlali Housing Cooperative in Nyanga, townships situated not very far from the Cape Town CBD, and occupied mostly by African communities. These two housing cooperatives participated in the national Hostel Redevelopment Program, an initiative propagated by the national Department of Human Settlements. Since these cooperatives participated in different ways during identifiable phases of the program, public participation by potential beneficiaries was researched within each phase. A comparison of research findings in the two programs points to a positive relationship between public participation and beneficiary satisfaction. Though other factors also play a role, such satisfaction could be observed in the Nyanga community where levels of participation by beneficiaries were extremely high. With the Welcome Zenzile beneficiaries, the same could not be said, inter alia, since most of the decisions associated with beneficiary interests were made by the City of Cape Town. In essence this second program was implemented by the City of Cape Town for and on behalf of the beneficiaries.
AFRIKAANSE OPSOMMING: In die algemeen veronderstel die literatuur oor openbare deelname dat daar ‘n kousaleverband bestaan tussen gemeenskapsdeelname aan stedelike ontwikkelingsprogramme en die tevredenheid van die begunstigdes van sodanige programme met die uitkomstes daarvan. In hierdie studie word twee hostelherontwikkelingsprogramme gebruik om die rol te ondersoek wat openbare deelname speel in die vorming van persepsies oor begunstigdes se tevredenheid of ontevredenheid. Die rol van openbare deelname word ondersoek aan die hand van die Internasionale Vereniging vir Openbare Deelname se Spektrum van Deelname-model, ‘n model wat ‘n stel beginsels voorhou waaraan voldoen moet word voordat daar gesê kan word dat begunstigdes doeltreffend aan ‘n program deelgeneem het. Die tevredenheid of ontevredenheid van die begunstigdes word getoets volgens die Hirschmann-model van ―Voice, Exit and Loyalty‖, ‘n model wat veronderstel dat moontlike begunstigdes van ‘n program – ten einde hulle tevredenheid of ontevredenheid met die proses te kan uitspreek – aan die program lojaal kan bly, hulle ontevredenheid daarmee kan betuig, of (as ‘n laaste uitweg) die program kan verlaat. Nadat daar ‘n ontleding van die konsep openbare deelname gedoen is, word die konsep toegepas – via onderhoude en steekproewe met belanghebbendes en potensiële begunstigdes – in twee verskillende belangegemeenskappe: die Welcome Zenzilebehuisingskoöperatief in Langa en die Ilinge LabaHlali-behuisingskoöperatief in Nyanga, twee townships wat nie ver van die Kaapstadse Sentrale Sakegebied geleë is nie en hoofsaaklik deur swart gemeenskappe bewoon word. Hierdie twee behuisingskoöperatiewe het aan die nasionale Hostelherontwikkelingsprogram, ‘n inisiatief wat deur die nasionale Departement van Menslike Vestiging geloods is, deelgeneem. Aangesien hierdie koöperatiewe op verskillende wyses tydens identifiseerbare fases van die program deelgeneem het, is openbare deelname deur potensiële begunstigdes in elke fase nagevors. ‘n Vergelyking van navorsingsbevindinge ten opsigte van die twee programme dui op ‘n positiewe verband tussen openbare deelname en begunstigdetevredenheid. Ofskoon ander faktore ook ‘n rol speel, kon sodanige tevredenheid in die Nyanga-gemeenskap waargeneem word, waar vlakke van deelname deur begunstigdes buitengewoon hoog was. Dieselfde kan egter nie van die Welcome Zenzile-begunstigdes gesê word nie, onder andere omdat die meeste van die besluite wat met begunstigdebelange te make het, deur die Stad Kaapstad geneem is. Op die keper beskou het die Stad Kaapstad hierdie tweede program vir en namens die begunstigdes geïmplementeer.

Full textAbstract:
Masters in Public Administration - MPAThe Beginning of the paradigm shift in policing in the South African Police was first seen in 1993 when the concept of Community Policing was first introduced. The South African Police Service that was formed through the Police Act 68 of 1995 subsequently adopted Community Policing as a Corporate Strategy of the organisation. There is a question as to whether some of the efforts reflect the necessary elements of community policing or are merely reactions to a contemporary political thrust for police reform. This study seeks to critically analyse the challenges and contradictions in Community Policing in terms of strategy and organisation. Nyanga SAPS will be use as the case study. Nyanga is one of the Police Stations in the so-called Black Township that has been engulfed by Community-Police conflicts since the democratic dispensation came into existence in South Africa. The highest point of this animosity saw certain people within the community between 1998 and 1999 reporting criminal activities to Taxi Operators rather than to the police. This study will be approached through gap analysis. The author will first describe the desired state of affairs in terms where the SAPS should be, in relation to reform policies put in place by the government. This will be followed by the analysis of the present situation in Nyanga, which will highlight the shortcomings. Then the study will put forward recommendations which should address the identified shortcomings. Based on that, the strategy that should inform policing in the new millennium will be developed. The author will recommend an African approach to policing as it has become apparent that the policing approaches are different for different countries and different communities. The author will propose full participation of the public in policing, in terms of determining policing priorities in their areas.

The argument put forth here is that the term diaspora evokes geographies of Identity and makes the whole Asian community a subject of study not only globally but also locally. The theoretical formulation underpinning this study is explored with the post-colonialtheoretical framework taking center stage as the tool of analysis. The Indian question within the Kenyan context is raised in this chapter as the basis upon which Afro-Asian socioeconomic and political contestations were anchored on. It is against this background that Afro-Asian socio-economic relations in Nyanza and Western provinces of Kenya are discussed. These discussions are supported by epistemological and empirical evidence obtained from oral informants, secondary and primary data across the two provinces of study

The nyala on Buffelsdrift Private Game Reserve were found to be mainly browsers and made little use of grass during the study period. Browse contributed 87.8 percent to the annual diet, while grass contributed 12.2 percent. Only six species formed > 5 percent of the annual diet. Of these six only three species formed > 10 percent. They are the shrubs Acacia karroo, Pappea capensis and Grewia robusta. These were followed by the shrub Portulacaria afra, the dwarf shrub Zygophyllum lichtensteinianum and the grass Cynodon dactylon all contributing between 5 - 10 percent. There were definite seasonal dietary shifts with preference to different plant species. The shift takes place between the wet seasons (winter and spring) and the dry season (summer). Herbaceous species such as Cynodon dactylon and Erharta calycina were favoured in the winter/wet season. Shrubs such as P. capensis, P. afra and dwarf shrubs such as Limeum aethiopicum and Z. lichtensteinianum were favoured during the spring/wet and summer/dry seasons. Nyala habitat use in BPGR differed significantly from expected use when taking the relative area of habitats into consideration. However nyala did not display signififcantly different habitat preferences between seasons. Male and female nyala displayed differences in foraging behaviour at the plant form, plant species and habitat scale. Males preferred a greater proportion of shrubs and females a greater proportion of dwarf shrubs. Males preferred the shrubs Pappea capensis and Portulacaria afra the most and females preferred the dwarf shrubs Limeum aethiopicum and Zygophyllum lichtensteinianum the most. Plant species site availability varied significantly between the sexes, indicating that males and females selected different feeding paths. The difference in their feeding strategy appears to be related to the selection of plants that best satisfy the nutrient requirements of each sex. These findings are in agreement with the results from earlier studies on nyala sexual dimorphism. At the habitat scale females selected more for open dwarf shrubland and males more for densely vegetated habitats. This appears to be as a result of males attempting to maximize their foraging opportunities by selecting areas that offer food in greater quantities. Nyala in BPGR appear to co-exist with kudu and eland through spatial resource partitioning. This is suggested to be due to the influence of body size-gut size relationships on forage selectivity.

Full textAbstract:
The concept of community development is founded on the premise that changes in the living conditions of people are best effected by the people themselves. The term community evokes the idea of a homogeneous social group who can recognise their common interests and work together harmoniously for their common good. The concerns of the leading development agents and donors in the past two decades have been on empowering communities to participate in their own development by taking control of decisions and initiatives that seek to improve their living conditions. The zeal to address these concerns has in the past decade been pushed with such resounding statements that people&rsquo
s participation in development projects has not only been seen as a basic human right, but also as an imperative condition for human survival. It has been strongly argued in the UNDP reports that the overall development strategy is to enable people to gain access to a much broader range of opportunities.
From this perspective, development as a social activity seeks to ensconce economic liberalisation, freedom of association, good governance and access to free market economy as the guiding tenets of an improved life in all communities in the world. The realization of this dream posed a major challenge to many governments in the Third World and the 1980s saw the emergence of &lsquo
associational revolution&rsquo
&ndash
the proliferation of small-scale non governmental organizations (NGOs) with relative autonomy from the state. The mainstream development agencies perceived the NGOs as the best instruments to instigate changes in the living conditions of the poor and the disadvantaged people. For this reason, NGOs became increasingly instrumental in implementing development objectives in the rural and disadvantaged communities. Development in this sense consists of processes in which various groups are stimulated to improve aspects of their lives particularly by people from outside their community. This has drawn attention to how these outsider- development agents communicate development information particularly due to the sociolinguistic situation in many rural African communities. The real concern is with is that the target majority of the people in the rural areas are not speakers of the dominant languages of the development discourse, in most cases this is the official foreign languages taught in schools.
Communication is a fundamental part in community development programmes and language emerges as a key factor in effective communication and implementation of these programmes. While it is evident that social interactions are sustained by agreeable communicative principles, the role of language and the different mode of communication applied to development interventions have received very little attention from the parties concerned. This has yielded detrimental repercussions in the quality of interaction at the grassroots level. More often than not, it is assumed that once there is a common language, effective communication will take place and for this reason language use and mode of communication are never given much thought in the field of development interaction.

The access to water in the regions around Lake Victoria varies with the rainy seasons. Today the daily labor of fetching water is a heavy burden for people in the rural areas. In the process of this study farmers in the Western and Nyanza provinces in Kenya are interviewed, water samples are analysed and present rainwater harvesting techniques and purification methods are observed. As a result, suitable solutions to the problems found are discussed. An optimal system is chosen for the region with a concept selection matrix. An elaborated dimensioning tool for roof and purpose-built harvesting systems is developed. Finally a summarized manual is attached in order to raise interest for rainwater harvesting among the farmers that the non-governmental organisation SCC-Vi Agroforestry cooperates with.

Pays riche, producteur de pétrole, le Gabon accuse un très grand déficit en matière de transports et de communications. Au sortir de l'Indépendance, le pays a adopté une politique d'aménagement du territoire qui a débouché sur l'élaboration des plans quinquennaux de développement. L'objectif était de désenclaver le territoire. Les premiers plans et les politiques conduites dans les années soixante ont visé à mettre en place des liaisons nationales routières, aéroportuaires et des télécommunications vers et entre les chefs-lieux des provinces afin d'introvertir l'organisation des dessertes pour affirmer l'unité nationale et favoriser le développement des régions. Malheureusement, les réalisations accomplies n'ont pas été à la hauteur des attentes. Lorsque les réseaux de communication sont déficients et dégradés, ils ne jouent plus leur fonction de liaison et l'économie en souffre tout comme les régions, le cas de la Ngounié et la Nyanga. Il est temps de les sortir du sous-développement pour mieux les intégrer économiquement et socialement. La nouvelle politique de diversification de l'économie mise en place par le gouvernement gabonais pour préparer l'après-pétrole, ne peut aboutir sans un effort considérable porté à la construction des réseaux de communication efficaces répondant aux besoins du pays et capables de desservir la totalité des régionsRich country, oil producer, Gabon records a very great deficit transport communications. With leaving Independence, the country adopted a land settlement policy which led to the development of the five-year plans of development. The objective was to disenclose the territory. The foregrounds and the policies led in the Sixties aimed at setting up road, airport national connections and telecommunications towards and between the chief towns of the provinces in order to introvertir the organization of the service roads to affirm the national unit and to support the development of the regions. Unfortunately, the accomplishments were not worthy of waitings. When the communication networks defective and are degraded, they do not play any more their function of connection and the economy just like suffers from it the areas, the case of Ngounié and Nyanga. It is time to leave them the underdevelopment for better integrating them economically and socially. The new policy of diversification of the economy installation by the Gabonese government to prepare after-oil, cannot lead without a considerable effort carried in the building of efficient networks of communication meeting needs of the country and able to serve the totality of the areas

Full textAbstract:
A number of researchers have explored the toll of AIDS on the children who have become orphans as a result of the disease; others have investigated the roles of aid-giving agencies on the alleviation of the orphans' situation. However, despite researchers' pointing to the germaneness of community and goodwill agency liaison, no study had examined the impact of such collaboration on the resources available to the orphans. To this end, the heads-of-household of 532 AIDS orphans under 18 years old in Kenya's Nyanza province were surveyed to investigate the impact of community-referral on the state of AIDS orphans with regard to homelessness, birth registration, food security, school attendance, and sibling separation. The theoretical framework for the study was rooted on the interplay of resource-availability and stressors on AIDS orphans. Results of regression analysis showed that double orphans ate fewer meals than maternal or paternal orphans. There was an inverse relationship between the number of AIDS orphans in a home and the likelihood of homelessness; older orphans tended to not be separated from their siblings; double orphans were more likely than single orphans to be separated from their siblings; school absenteeism was higher among older orphans and when the head-of-household was female; community-referred, male children, offsprings of the respondents tended to have birth registration. The results of the assessment will be pertinent to stakeholders as a framework to guide program planning and implementation as they address the needs of AIDS orphans in Nyanza province and other similar communities.

Full textAbstract:
Includes bibliographical references.This dissertation explores the use of qualitative methods to research community health workers' (CHWs) perceptions of mental health problems in Khayelitsha and Nyanga, two peri-urban Black townships in the Cape Town area. Since the historic WHO-UNICEF meeting at Alma-Ata in 1978, there has been widespread interest in the concept of CHW s as the ideal work force for advancing the principles of the primary health care (PH C) approach. In seeking to transform the structure and delivery of mental health care in South Africa within the confines of limited financial and human resources, policy makers are shifting attention to the integration of mental health care within a PHC framework. Fundamental to the PHC agenda, as conceptualised at Alma-Ata, is health care that is based on appropriate technologies and that encourages effective community participation in making decisions about health issues. In the past few decades, anthropological perspectives gained from cross-cultural research into health beliefs and practices have made valuable contributions to the planning and implementation ofPHC programmes. In the field of medical anthropology, hermeneutically orientated approaches play an important role in advocacy, whereby the patient's perspective on illness and the meaning of illness is brought to the fore in an attempt to provide more patient-centred care. In this research, CHW s were interviewed to gain insight into the scope of primary mental health care, as perceived by them, and prevailing beliefs and practices surrounding mental health problems. Unstructured individual interviews were conducted with 20 CHW s working in community-based PHC projects in Khayelitsha and Nyanga to elicit their personal accounts of mental health problems in their geographical communities. This material was used to construct five vignette descriptions of mental health problems in the CHWs' own words. Kleinman's explanatory model approach was used in structured individual interviews to access CHW s' understandings of mental illness. Questions related to naming the problem; theories of illness causation; coping with the problem; and decision-making as regards treatment options. Focus group interviews were held with the participants of two of the CHW projects to explore their feelings about involvement in mental health care. This micro-level analysis was accompanied by the perspectives of critically-interpretive medical anthropology which shifts attention beyond the individual cultural construction of illness to the political and economic factors affecting the social organisation of health care. Within the PHC setting, the critical perspective entails challenging constraints to the attainment of health for all as a result of inequities in the distribution of power and wealth; barriers to achieving community participation in health issues; and inequitable access to basic primary health needs by the most disadvantaged.

Full textAbstract:
Most contemporary urban development in cities of the global South is responding to rapid urbanisation caused by prospects of employment opportunities and improved quality of life. Research in the field of sustainability in cities of the global South mainly focuses on economic and social development goals. However, there is an emerging sense that an appreciation of ordinary, everyday practices at the level of the community is important for developing a nuanced understanding of what sustainability might be in Southern cities. There is agreement on the need to pay attention to social and cultural practices in urban sustainability literature; yet relatively little research in the field engages closely with everyday practices at the level of neighbourhoods or communities. This is particularly true in the global South, and especially in low-income urban neighbourhoods, where developmentalist agendas dominate both academic and policy-related research. My thesis addresses this gap through an exploration of a wide range of everyday practices in a lowincome, peri-urban area, which happen to have sustainable effects. Analysing ethnographic data collected over nine months in the Cape Town township of Nyanga, I find that the desire of urban residents to create spaces of home and belonging drives behaviour that in fact has positive sustainable outcomes, yet is seldom considered in literature on sustainable cities. I argue that paying attention to how ordinary citizens ‘make home', specifically by (i) drawing on memories, (ii) developing livelihoods, and (iii) building social relations can enrich understanding not only of economic and social development but also of the complex ways in which social and environmental sustainability are already intertwined in everyday practice. Facilitating sustainable spaces in cities of the global South, therefore, requires critical engagement with the practices that are already taking place in urban residents' everyday lives.

This study is an outcome and impact evaluation of Concern Worldwide (CW) community feeding program. Concern Worldwide conducted a community feeding program in Nyanga District in 2012. It was responding to the National Food Report (2011) issued by the government on the food shortages in Nyanga District. The feeding program supported Nyanga communities with nutritional supplements and food provisions to households. The goal of Concern Worldwide was to address the problems of hunger, household food insecurity, malnutrition and poverty which were affecting people in Nyanga. Four evaluation questions about program outcomes were used as a framework for the evaluation and included: How feasible are livelihood feeding schemes as methods of providing food safety net?; How are short-term emergency programmes converted into long term benefits for communities?; What are the interventions available in the program to ensure fulfilment of goals and community empowerment?; What lessons can be derived from the projects that can be used in future by Concern Worldwide and other NGOs involved in emergency and other developmental projects? For the purposes of the study three data sources were consulted. These included program documents, CW officials and beneficiaries. Data collection methods used included face to face interviews and both closed and open ended questionnaires. The qualitative data was analysed through content analysis and presented graphically and descriptively. The findings showed that the community feeding program made some impact through food provisions and agriculture inputs to the beneficiaries which was highly regarded and appreciated. It also managed to provide training on drought resistant crop farming and management of harvests. Monitoring and evaluation of the feeding program was identified as a critical tool in creating efficiency and accountability of the program. Although training was provided to all the beneficiaries, not all were directly involved in the daily routine activities of the program a goal that is not achievable in the context of community feeding program.

Full textAbstract:
The 80 x 20 km Migori segment of the Nyanza greenstone belt, Kenya, lies within the Archean Tanzanian Craton (2.8-2.5 Ga). Volcanic facies mapping has delineated eleven formations comprising the Macalder and Lolgorien Subgroups of the Migori Group. The subgroups represent adjacent volcanic centres with well-developed central and proximal facies, and interfingering distal facies. Rocks at the base of the group are submarine tholeiitic basalt and dolerite, and calc-alkaline dacite and rhyolite; overlying subaerial dacites and late granite intrusions define a high-K calc-alkaline suite.

Full textAbstract:
Bibliography: pages 344-361.In this thesis I outline the history of Nyanga up to 1970. Diverse aspects are covered, including location politics, women's protests, rent arrears and boycotts, and gangsterism. There is a special focus on housing issues, for they were related to most facets of location life and demonstrated the contradictions within apartheid policy. Four themes are followed throughout the thesis. First, the extent to which the state achieved control of the African urban population is assessed, particularly in terms of its housing and influx control policies. I argue that the formulation and implementation of policies were influenced minimally by pressures "from below", and that central and local authorities achieved extensive control over the lives of urban Africans. Nevertheless, government officials did not succeed in curbing African urbanisation or controlling the residential movement of urban Africans, as witnessed by the high number of "illegal" Africans and consistently high tenancy turnover. A second topic that threads its way through the thesis is the role of African constables and clerks in Nyanga. I show that residents working with the location administration were attracted particularly to the material benefits of collaboration. Utilising their linguistic skills and knowledge of location inhabitants, they extracted money and sexual favours from Nyanga residents and were given first priority in the allocation of Old Location houses. They did not, however, form an identifiable social group as they came from diverse occupational and educational backgrounds and did not associate closely with one another. A third theme is the differential impact of apartheid laws on African women. I outline the laws that applied to urban African women and describe the actual process by which they were expelled from the Cape Peninsula. Arising from this, the changing nature and scope of women's demonstrations in Nyanga is described. My research shows that the protests of the early 1950s, which were small, infrequent, and centred on local issues, broadened in the late 1950s to include the application of pass laws to African women. The reasons for the change are shown to be both political and material in nature, with their origin in the forced removals from Peninsula shack settlements. Fourthly, I have concentrated on spatial dynamics at various points. There were significant differences in physical space between Mau-Mau and the Old Location, which contributed to the social distance between the two neighbourhoods. During the massive "black spot" clearance campaign of the 1950s, the authorities succeeded in gaining spatial control over Africans by forcing them into segregated, fenced locations where entry and exit was monitored. To counteract this, residents asserted their control over the transit camp by constructing shacks in such a way as to impede raiding pass officials and make administrative surveillance of their lives difficult. The contradictory effects of placing contract workers in accommodation next to families are also examined: on the one hand, there was considerable socialising and cooperation between the two groups; on the other, much friction developed over the relationships between women in the married quarters and men in the hostels.

Full textAbstract:
Dans le Supergroupe Ouest-Congolais du bassin du Niari-Nyanga (Afrique centrale), les marqueurs des Glaciations Globales Sturtienne et Marinoenne sont représentés par les formations des «Diamictite inférieure» et «Diamictite supérieure».Ce travail de thèse présente une étude à haute résolution du Cap Carbonate associé à la Diamictite supérieure (6 coupes dans le bassin et 2 coupes dans la zone externe de la Chaîne du Mayombe). Les études pétrographiques révèlent la préservation des structures sédimentaires primaires et permettent de définir six microfaciès (MF0 à MF5) caractéristiques des paléoenvironnements de types inter- à supratidaux ou subtidaux. Dans le Cap Carbonate étudié, les indices de Kübler montrent une évolution croissante depuis la diagenèse profonde dans le bassin jusqu'à l'épimétamorphisme dans la zone externe de la Chaîne du Mayombe. Le signal isotopique ([delta]13C et [delta]18O) des Cap Carbonate échantillonnés est généralement reproductible dans le synclinal comme dans la chaîne, avec les valeurs du [delta]13C montrant une excursion négative variant de -2.6 [pour mille] à -5.6 [pour mille]. Les valeurs de d18O oscillent entre -6 [pour mille] et -12 [pour mille]. Par ailleurs, la confrontation des données minéralogiques, chimiques et isotopiques indique une influence négligeable des transformations post-sédimentaires sur la signature isotopique du Cap Carbonate indiquant la préservation des valeurs du [delta]13C de l'océan néoprotérozoïque. Enfin, l'ensemble des données de cette thèse et les résultats préliminaires des « Projets GLANEC» replacés dans un contexte régional permettent de définir le Membre SCIa du synclinal du Niari-Nyanga comme un Cap Carbonate lié à la Glaciation MarinoenneWithin West-Congolian Supergroup of Niari-Nyanga Basin (Central Africa), the markers of Sturtian and Marinoan Global Glaciations are documented by the so-called «Lower Diamictite» and «Upper Diamictite». This work is based on 6 and 2 lithological sections from the basin and the external zone of the Mayombe fold belt. It corresponds to a high-resolution study of the Cap Carbonate lying unconformably on the Upper Diamictite. Petrographic analyses show preservation of primary sedimentary structures and lead to define six microfacies (MF0 to MF5). These microfacies caracterize paleoenvironments such as inter- to supratidal or subtidal types. Kübler index values of the studied Cap Carbonate display an increasing evolution from East to West, ie from a deep diagenesis in the basin to an epimetamorphism in the Mayombe external zone. Stable isotope signature ([delta]13C, [delta]18O) of the various components of this Cap Carbonate is reproducible throughout the basin as in the Mayombe external zone, with [delta]13C values displaying a negative excursion, decreasing from -2.6 ? to -5.6 ?. [delta]18O values of these components vary between -6 ? and -12 ?. Moreover, comparison between mineralogic, chemical and isotopic data indicates that post-sedimentary transformations had a very negligible influence on the isotopic signature of the Cap Carbonate, indicating preservation of d13C values of the Neoproterozoic ocean. Finally, when they are compared with other regional studies, all data of the present work and the preliminary results of the GLANEC Projects lead to the conclusion that the SCIa Member of the Niari-Nyanga Basin must be considered as a Cap Carbonate related to the Marinoan Global Glaciation

Full textAbstract:
In order for the SADC/GEF Lake Malawi/Nyasa Biodiversity Conservation Project to draw out sound strategic management and conservation recommendations to the riparian countries of Malawi, Mozambique and Tanzania, the need and urgency for revising the taxonomy of some of the scientifically and economically important fish groups was accorded high priority. This study is a contribution towards achieving those goals. It is a taxonomic revision of the shallow-water species of the genera Taenioiethrinops, Tramitichromis and Lethrinops. These three genera are grouped as Lethrinops 'sensu lato' in this thesis, corresponding to the definition of Lethrinops prior to the revision by Eccles & Trewavas (1989). All members have a characteristic dentition: the outer teeth in the lower jaw curve inwards posteriorly ending just behind the inner row(s), rather than continuing backwards as a single series, as in most other Malawian haplochromines. The decision to consider shallow-water Lethrinops 'sensu lato' separately from the deepwater ones was not arbitrary, but rather based on available ecological and morphological evidence. Unanticipatedly, on the course of this study, evidence from molecular genetics has helped to strengthen the distinction. Economically, Lethrinops is important for human food and for the aquarium trade. Lethrinops are precocial fish producing very few young at a time and are consequently unlikely to recover quickly from heavy fishing pressure. To evolutionary biologists, Lethrinops 'sensu lato' is challenging because until now most theories about the evolution of Lake Malawi cichlids have not taken the sand-dwelling fishes fully into consideration. A better knowledge of the distribution patterns of these cichlids, of which Lethrinops are the major representatives, can help in explaining the underlying mechanisms of speciation in sand-dwelling cichlids. Lethrinops 'sensu lato' is taxonomically one of the most complex groups of Lake MalawilNyasa haplochromines. The species are closely related and very difficult to differentiate, and the taxonomy is confused and in urgent need of revision. This is more important since taxonomy plays an important role in most of the key criteria of conservation.The principal objective of this study was to carry out a taxonomic revision of this group and to provide a key to the identification of the species. Further objectives include the mapping of their distribution and analysing their phylogenetic relationships. Large samples were collected (by trawling, gill netting, beach seining and purchased from local fishermen) from depths less than 20m and from numerous well-defined localities all around the lake. Seventeen type specimens of the 21 described species of the shallow-water Lethrinops 'sensu lato' were examined and compared with this recently collected material. The data of about 500 fish specimens were subjected to principal component analyses (PCA). To further evaluate morphological differences between taxa of comparable size, non- parametric, distribution-free Mann-Whitney U-tests were used. Within the shallow-water Lethrinops 'sensu lato' three genera are recognized which can be separated by characters such as head shape, pharyngeal morphology and dentition, number and shape of gill-rakers, number of the pectoral fin rays and melanin pattern. So far in this study, 28 taxa have been recognized. The overlapping measurements and meristics compound the difficulty inherent in the identification and classification of members of the three genera. The genera Tramitichromis and Taeniolethrinops are typically shallow- water taxa. Within the genus Taeniolethrinops four described species, (T. cyrtonotus, T.forcicauda, T. laticeps and T. praeorbitalis) were distinguished. Within the genus Tramitichromis nine species were distinguished, five of which are described (T. brevis, T. intermedius, T. lituris, T. trilineata and T. variabilis); four represent undescribed species and are given a working name (T. sp. 'brevis 2', T. sp. 'maculae', T. sp. 'pharyngeals' and T. sp. 'variabilis deep'). For convenience, the shallow water Lethrinops 'sensu stricto' were divided into three natural groups, according to shared morphological features. • The first group is the lethrinus group, including three species (L. lunaris, L. leptodon and L. lethrinus) with relatively lolong snouts and remnants of the horizontal stripes. • Another group included eight taxa (L. microstoma, L. macrophthalmus, L. macrochir, L. auritus, L. parvidens, L. sp. 'parvidens deep', L. 'black dorsal auritus', L. sp. 'domira blotch' and L. sp. 'turneri') with a relatively short snout and a small mouth set low on the profile. Within this group, special attention has been paid to the confusion involving L. auritus and a new species to be described soon, L. sp. 'turneri' . • The last group of Lethrinops 'sensu stricto' is ill defmed and has an intermediate snout and with a lesser round head. Within this group L. oculatus, which was described on the basis of a single specimen, is synonymised with L. marginatus. The other valid species of this group are Lethrinops albus and L.furcifer. Nearly all species seem to have a lake-wide distribution. All are associated with sandy substrata where they feed mainly on insect larvae and ostracods. Mitochondrial DNA sequence data indicate that Lethrinops 'sensu lato' as currently defmed is not monophyletic but is paraphyletic or more probably polyphyletic. It is further suggested that the typical Lethrinops dentition provides no particular strong evidence for affimity among shallow-water Lethrinops s.s., Tramitichromis and Taeniolethrinops. The need for management and conservation of this scientifically exciting group of fishes has been pointed out.

Full textAbstract:
The current study aimed to describe the paradox of risk through an exploration of the experiences and perceptions of sexuality and HIV/AIDS among physically disabled young people in Nyanga, South Africa. This is against the background that AIDS has become a national and global crisis, which requires all people to participate in efforts to contain the pandemic. Yet literature indicates that young people with disabilities are not participating in such efforts. There is also an assumption, that physically disabled young people do not experience challenges in expressing their sexuality and accessing HIV/AIDS prevention services, to the same extent as other disability groups such as the blind and those with intellectual disabilities. Hence there was a need to explore disabled young people&rsquo
s own understanding of risk and the factors that hinder or support their participation in existing sexuality education and HIV/AIDS prevention programmes. It was also important for this group to suggest ways in which they may participate in such programmes.

Ecological sanitation, or ecosan, refers to a range of sanitation technologies in which human excreta is recovered and retained on-site, and eventually reused. However, when a culture does not have a tradition of reusing or handling human waste, what would motivate a household within that culture to recycle and reuse their waste? More specifically, how do the agricultural value of the material from an ecosan toilet and user perspectives on ecosan systems influence households' adoption of ecosan toilets? On average, households in the study area produce 4 kilograms of nitrogen and 0.6 kilograms of phosphorous per year from urine collected in the skyloo toilet, the type of urine-diverting ecosan toilet available in the study area in the Nyanza Province, Kenya. These nutrients are the equivalent of a cost savings of about US $12 per year (the GDP per capita in Kenya in 2004 was US $1 100). About two-thirds of the households reuse the processed feces and urine in household gardens. Users reported additional major benefits such as the absence of foul odors, inexpensive construction costs (partly due to a materials subsidy by the promoting NGO), and the aesthetic value/social status that the facility brings to the owners' homes.
(cont.) The major negative factors included problems with construction and design of the facility, training new users-especially children-how to use the toilet, and handling human excrement. The findings suggest that ecosan is a viable sanitation option that fills a niche within this region of Kenya. Ecosan's comparative advantages seem to be significant enough to outweigh negative cultural sentiments regarding the handling of human excrement to some user groups. Such user groups include the very poor who practice household agriculture (those who have trouble affording commercial fertilizer and also have reason to want it), those who live in areas with high nutrient loads to natural waters, households with an exceptional environmental conscious, and households in which adverse hydrogeologic conditions (such as a high water table or loose soils) make pit latrines an environmental and human health hazard. In addition to household-level advantages, the niche that ecosan fills has the potential to make headway towards the Millennium Development Goals' provision of sanitation, and to be a valuable contribution to integrated water resource management strategies.

Denna studie har gjorts i syfte att undersöka nyexaminerade socialarbetares arbetssituation samt för att skapa förståelse för vilka utmaningar de möter i arbetet och hur de hanterar dessa. Med anledning av att resultatet speglas av höga arbetskrav och olika strategier användes krav-kontroll- stödmodellen samt coping för att analysera empirin. I studien har en kvalitativ forskningsmetod använts och intervjuer har gjorts med fem nyexaminerade socialarbetare. Vidare har tidigare forskning inom området som socialarbetares första tid i yrkesrollen, kollegialt stöd, socialarbetares kravfyllda arbetsmiljö, verktyg för att hantera arbetsmiljön samt konsekvenser av den analyserats och använts i arbetet. Resultatet visade att det finns en koppling mellan en bra introduktion och upplevelsen av en god arbetsmiljö. Respondenterna vars upplevelser av en bristfällig introduktion, gav uttryck för en känsla av hög arbetsbelastning och stress. Stressupplevelser varierar samtidigt som respondenterna visar på olika metoder för att hantera sin arbetssituation. Beskrivningar har getts av arbetsplatsens förebyggande arbete för att skapa god arbetsmiljö samt respondenternas upplevelser av det kollegiala stödet. Vidare framgick deras känsla av otillräcklighet inför klienterna.This study has been conducted with the aim of examining the work situation of newly graduated social workers. This to create an understanding of the challenges they face at work and how they handle them.

Furthermore, has previous research in the field as a social worker ́s demanded work environment, tools for managing the work environment and consequences of it been analyzed and used in the study. The result showed that there is a link between a good introduction and the experience of a good working environment. The respondents, whose experiences of a poor introduction, expressed a feeling of high workload and stress. At the same time stress experiences vary as respondents show different methods for managing their work situation. Descriptions have been given of the workplaces preventive work to create a good working environment and respondent ́s experiences of the collegial support.

Full textAbstract:
La construction identitaire du sujet relève du vaste champ sémantique de l'identité en général, et de l'identité personnelle en particulier. A l'heure de la modernité, c'est- à- dire de l'affirmation du sujet, le sens et la valeur du processus identitaire interrogent de manière transversale les sciences humaines et sociales. En littérature francophone, la construction identitaire du sujet romanesque africain, se complique des rémanences d'un environnement référentiel également en mutation socio- culturelle, A partir du corpus de quatre romans des auteurs gabonais Angèle Rawiri et, Jean Divassa Nyama, la présente étude s'intéresse au processus identitaire d'un sujet à la fois urbain et rural, qui en dépit de plusieurs stratégies développées, vérifie par son échec la thèse du « héros » problématique.Au regard des implications formelles, psycho- sociologiques et culturelles de notre objet d'étude, nous avons retenu une approche anthropologique, à savoir plurielle, pour mieux en cerner les nombreux contours.La première partie, descriptive, dresse le contexte socio- culturel auxquels s'alimentent les facteurs exogènes et endogènes de la crise identitaire du personnage. Celle – ci naît surtout du désir d'une nouvelle identification du personnage par rapport à soi et à son milieu, sous la pression d'une modernité exigeante. La diversité des situations du sujet débouche sur une stratégie d'affirmation identitaire multiforme, où dominent à la fois le goùt du pouvoir, le besoin de sécurité affective et l'enjeu culturel.Le deuxième axe voit le personnage- sujet lancer sa dynamique de quête, selon une configuration narrative et actantielle, articulée par une stratégie déterminante de modalités cognitives et pratiques.La dernière partie place le paradigme spatial au centre de la sémantique de la construction identitaire du sujet: cela débute par le cadre spatio- temporel africain en tant que structurant extérieur de l'aventure, auxquels s'ajoutent une intériorité et un imaginaire investis à la fois d'une valeur fonctionnelle et d'une forte symbolique. Enfin, l'importance accordé par le sujet au jeu relationnel sur son parcours identitaire contribue à notre sens à signifier l'importance de sa transformation intérieure. Il ressort en conséquence que l'émergence du sujet africain passe par l'enrichissement de son Être, à travers une vraie connaissance de soi et de ses valeurs culturelles, pour mieux exister au mondeThe identity shaping of the romantic subject owes to a large semantic field of identity in general, and of personal identity in particular. At the time of modernity, and more precisely, of the assertion of the subject, the sense and value of the identity process imply transversal clarification with the help of social and human sciences. As far as francophone African literature is concerned, the identity shaping of the romantic subject in the novel is facing the persistences of a referential environment which is submitted to sociocultural mutation.Applied to a corpus of four novels written by two gabonese authors, Angele Rawiri and Jean Divassa Nyama, the current study concerns the identity process of the romantic subject who is sharing rural as well as urban environment, and who, despite several strategies at stake, responds though his failure, to the concept of the problematic “hero”.Consequently, the emerging process of the African subject depends on the improvement of his being, through a real knowledge of himself and his cultural values. That is the best way for him to assert his existence in the world

Full textAbstract:
The purpose of the study was to establish the current state of public research-extension-farmers linkages in Nyanga district of Zimbabwe. Public agricultural research and extension are custodians of agricultural development. This is not to disregard other private and Non-Governmental Organisations (NGOs). The quantitative study had a target sample of 150 communal farmers (N=150) which were systematically sampled from the three clusters in Nyanga districts? wards 19 and 22 as well as 12 extension officers (N=12) and six research officers (N=6), all of the responded well to the questionnaires. The data from the completed questionnaires was analysed using SAS Enterprise Guide version: 43.
The study revealed that the frequency of communication and communication channels used by the three stakeholders does not suggest or support any proper structural linkages. However, farmers were satisfied with the frequency of communication and the overall work of extension officers in promoting farmer development. They also appreciated the practical and useful information they receive from the extension officers. However the same could not be said for the research officers. Farmers indicated that they are not satisfied at all by the services they receive from research officers from Nyanga Experiment Station (NES). All farmer respondents from Sedze cluster have never engaged with research officers from NES in any farming business yet they are only 30km away from NES. In other words, the farmer-research and research-extension contacts are almost non-existent while the farmer-extension contacts are relatively better. Throughout this study, there were some contrasting responses from both research and extension officers and the farmers. The public officers rated the services they offer to the farmers as very good but the farmers never rated them that good. Other findings revealed that there are no organised farmer-research-extension linkages. Only low levels of informal networks exist between farmers and extension officers. There were reports of a research-extension steering committee but there were no indications of its functionality in this study. The decisions on research themes are done at the research head offices (top-down approach) robbing the farmers and even the frontline extension officers of the opportunity to contribute. There was great excitement shown by farmers from Manjoro and Weaving clusters who are working with research officers from NES on organic pesticides trials. This indicated that farmers are so much willing to engage researchers in activities that are aimed at improving farmer development.
The merger of Agricultural, Technical, and Extension Services (AGRITEX) and DR&SS did not improve technology generation and dissemination, rather it created confusion, overlaps and duplication of duties. This was reversed in 2010. The public research and extension officers are working under severely stressed budgets, a situation that could be a major contributing factor in job burnout being experienced by research officers. However, under these conditions both research and extension officers indicated that they are energetic and proud as well as hard working on their job. They further hold some pride in working for their departments where they foresee good future prospects. They have also accomplished worthwhile things in their lives as a result of their job. Both sets of officers also indicated that coordination problems are experienced in their work and that they require in-service training to deal with the ever changing environment under which they work.Dissertation (MSc)--University of Pretoria, 2015.

Full textAbstract:
Cette thèse porte sur l’étude de la filière palmier à huile au Burundi. Son enjeu principal est d’analyser la manière dont cette culture construit son territoire. Elle étudie les acteurs de la filière palmier à huile, leurs stratégies et la manière dont ils sont organisés ainsi que l’espace territorialisée par cette filière. La filière palmier à huile au Burundi a connu deux importants modes de cultures. Le mode de culture traditionnelle dominé par l’ancienne variété « dura », il était caractérisé par la polyculture extensive. Entre des palmiers espacés, la culture du vivrier était possible. Le deuxième mode de culture concerne la monoculture du palmier à huile qui est uniquement destinée à produire de l’huile de palme. Il consiste à la culture de la nouvelle variété « tenera » jugée plus productive que l’ancienne variété. La transition de l’ancien au nouveau mode d’exploitation agricole ne s’est pas faite sans conséquences sur les modes de vie des paysans des principales zones palméicoles burundaises (Rumonge et Nyanza-Lac). L’installation de la nouvelle variété « tenera » à Rumonge et à Nyanza lac a certes, généré une véritable agriculture marchande, mais elle s’est faite au détriment d’autres cultures vivrières. Dans ce travail nous montrons les bouleversements socio-économiques que la culture a engendrés sur les modes de vie des paysans, notamment l’exacerbation des conflits fonciers. La culture du palmier à huile ne cesse de s’étendre sur d’autres régions du pays. Par une analyse historique, nous montrons comment la construction du territoire du palmier à huile s’est faite autour des acteurs qui n’ont ni les mêmes moyens financiers ni les mêmes objectifs. Les modes d’organisation et les stratégies varient en fonction de chaque groupe d’acteurs et de son capital financier initial. La faible organisation de petits palméiculteurs observée à l’Imbo-sud n’augure pas un bon avenir pour eux. Enfin, l’étude montre comment les détenteurs de capitaux accèdent à la filière palmier à huile en passant par la simple location de terres de pauvres paysansThis thesis focuses on the study of the palm oil chain in Burundi. Its main aim is to analyze how this culture constructs its territory. It studies palm’s actors, their strategies and the way they are organized and the territorialized space by this chain. The palm oil chain in Burundi has experienced two important modes of cultures. The traditional method of farming dominated by the old variety "dura" and was characterized by extensive polyculture. Between spaced palms, food crops growing were possible. The second concerns the method of cultivation of monoculture oil palm which is only intended to produce palm oil. It involves cultivation of the new variety "tenera" considered more productive than the old variety. The transition from the old to the new farming method did not without consequences on the livelihoods of farmers in major palmicole areas Burundi (Rumonge and Nyanza-Lac). The installation of the new variety "tenera" in Rumonge and Nyanza Lac, respectively entrusted to the Regional Development Company Rumonge and Nyanza Lake project has certainly generated a real commercial agriculture, but it was at the expense of other food crops. In this work we show the socio-economic upheavals that culture has generated the lifestyles of farmers, for example the exacerbation of land conflicts. The cultivation of oil palm continues to expand into other regions. Through a historic analysis of the construction of oil palm land, we show how the construction of the oil palm area is about actors who do not have the same financial means nor the same objectives. The modes of organization and strategies vary according to each stakeholder group and initial financial capital. The weak organization of small producers of oil palm observed in Imbo area does not augur a good future for them. For lack of means, are forced to sell their farms to wealthy people. Finally, the study shows how capital holders access to the palm oil chain through the lease of land from poor peasants

The aim of the study was to investigate local community contributions to the existing Malawi College of Fisheries curriculum with a focus on Chambo fishery. Chambo fish (Oreochromis species) is the most favoured fish in Lake Malawi. Chambo catches have declined over the years. Responding to the declining catches, the Fisheries Department is engaged in a number of management options to address the issues. Most of these management options are governed by scientific recommendations and do not consider the socio-economic situation of the people who are dependent on fishery. This approach to fishery has influenced the Malawi College of Fisheries curriculum. The existing curriculum is product-centred, developed by a consultant. During the development of the curriculum, there was little consultation with the lecturers and no consultation with the local communities who are using the resource. The fishing communities have been fishing for a long time and have acquired knowledge, skills and experience worth investigating for its potential role in improving the existing curriculum. Through the use of interviews, focus group discussions and workshops with local communities local knowledge was identified for inclusion into the curriculum. A review of the existing curriculum revealed that it has primarily technical focus, grounded in the protection, control and management of the fish stocks, while the local knowledge has a practical focus based on existing practices and requiring an understanding of the sources of the issues. There is also more emphasis on a historical perspective and the context in which fishing practices take place at the moment. It was evident from the study that local communities have much of knowledge, skills and experience gained over the years of fishing , and if properly utilised, it can improve the MCF curriculum. I therefore recommend in this study that the curriculum be reviewed in order to integrate and draw on the local knowledge through a deliberative and participatory process between the local communities and the government so that it addresses the needs of the local communities and improves the training of the extension workers.

Full textAbstract:
The study dealt with four themes of importance for conservation of T. buxtoni (hereafter MN). Firstly distance sampling technique involving transects and total count methods were employed to assess population size and dynamics of MN. The study revealed that the total population size of MN in the study area varied between 887-965 individuals at 95%CI, representing a reduction by about 48% from what was reported in 1980's and a reduction of about 74% from what was reported for 1969. However, due to contraction of its habitat, average densities of MN have increased from what was reported in 1980's. More than half (54%) of the population is represented by adults and the population has the a sex ratio of2:1 (~ : 0). The sub-population ofMN in Dinsho sanctuary is 'closed population' because no evidence was found to suggest that the D.insho sub-population is mixing with the rest. The study forecasts a continual decrease of MN population by a rate of about 2% - 5% annually if no action is taken to counteract it. No conclusive evidence was found to suggest that innate demographic traits of the·species have made significant contribution to observed decline in population size as many parameters (i.e., recruitment, rate of increase, age structure except male adult and calves group, and group size) were similar in 1983-85 and 2003-05. Secondlv, randomly laid plots along transect lines were used to describe the basic components (vegetation types) of the MN habitat range and assess how MN relates to them. Accordingly six major vegetation types were recorded in Gaysay grassland habitat; among which Hypericum bush, mixed vegetations and Artemesia bush are the most selected and hence most preferred by MN. Similar numbers of vegetation types were recorded in AdelaylDinsho woodlands; among which, montane open grassland and Hypericum woodland are the most selected and thus preferred vegetation types by MN. When all vegetation types pooled together, levels of browsing decreases significantly with increase in vegetation height; while increases with increase in patch size. However, positive correlations were observed hetween levels of browsing and vegetation hlight for Helichrisum species; while negative correlation for Artemesia and open grassland in terms of patch size. Thirdlv, the effects of livestock and humans on availability, structure and composition ofMN habitat were investigated. The result revealed that presence of livestock and humans had negatively affected vegetation structure, composition and habitat availability to MN. Moreover, presence of livestock and their signs (droppings) were negatively correlated with presence of MN and their droppings. Fourthly, structured questionnaire and interviews directed to randomly selected households in 7 villages were used to assess the attitudes, and awareness of the local communities towards conservation of the park's flora and fauna with particular emphasis on MN. About a quarter of respondents (26%) felt that they benefited while 55% felt that they experienced conflict from the park. The most important benefits identified were leasing of horses to tourist's (62%) and serving as tourist guide (44%). Significant majority (83%) of the respondents believes that there is lack of equity in benefit distribution. The main conflicts identified were resentment due to forceful relocation (84%) and livestock grazing restriction (74%). Perceived benefits and conflicts were significantly variable across livelihood strategy than proximity and duration of settlements. The majority of respondents (66%) believe that their presence in the area does not contribute to degradation of MN habitat, an attitude more commonly held among recent settlers than long-term settlers. The overall attitude of the local people towards the park appeared to be positive since, for example, 80% of respondents would support the park's conservation activities if given the chance, suggesting that there is scope to enhance cooperation and improve the-prospects for conservation of the MN and its habitat.
