- Description: Currently some confusion exists as to how health professionals should best respond to the psychological needs of those affected by disasters. Some have argued that early psychological intervention is essential and others have argued that early formal psychological interventions have no useful role in post trauma response. This study highlights the importance of considering both counselling and non-counselling factors as potentially influencing the psychosocial response of disaster victims. Although posttraumatic stress disorder (PTSD) is not the only mental disorder that can develop as a result of exposure to disasters, it is probably the most frequent and debilitating psychological disorder associated with traumatic stress. In this exploratorydescriptive study the researcher aimed to explore and describe psychologists’ perceived influences of early strategies on the psychosocial response to those affected by disaster. The researcher used non-probability snowball sampling to access participants. The sample consisted of 5 participants. Semi structured interviews were conducted. Content analysis was used to analyse the data obtained from interviews. Results that emerged from the data suggest that there are many factors that influence the psychosocial response to those affected by disasters. These factors include the screening process, needs of survivors, the method of choice for treatment, the timing of intervention, pharmacology, the South African context, training and planning. The study makes a contribution to the growing knowledge of early strategies in response to those affected by disasters.

- Description: The distribution of public green space within towns is frequently uneven, and influenced by attributes such as its location relative to the commercial core, as well as the ethnicity and relative wealth and education of the residents. Yet most studies are from large cities in developed countries. In contrast, this study reports on the distribution of public green space across 9 small towns in a developing country, namely South Africa, which offers a unique case study because of its former racially defined settlement patterns. We do so using GIS analysis of aerial photographs focusing on 3 types of suburbs in each town, defined on the basis of wealth as well as race-based history under the previous apartheid regime. The more affluent suburbs, inhabited mainly by whites, have the lowest density of housing and the highest area of green space per capita. Proportionally, they have a similar area under public green space as to the previously racially defined townships, but because of the lower housing density, they have a greater area per person. The newly built low-cost housing areas (termed RDP suburbs), occupied largely by poor black South Africans, are poorly endowed with public green space, and fare worse than the other 2 suburb types on all attributes measured. This needs to be addressed in further low-cost housing developments.

- Description: Field studies were conducted at Lincoln University of Missouri (USA) and Hokkaido University (Japan) to: (i) study the relationships between greenhouse gases emissions and soil properties, (ii) assess the influence of agricultural practices on greenhouse gas fluxes and soil properties and (iii) improve the quantification of greenhouse gases from soil in agricultural fields using geospatial technologies. Results showed that besides soil temperature (T), soil thermal properties such as thermal conductivity (K), resistivity (R) and diffusivity (D) and soil pore spaces indices such as the pore tortuosity factor and the relative gas diffusion coefficient (Ds/Do) are controlling factors for greenhouse gases emissions. Soil thermal properties correlated with greenhouse gases emissions when soil temperature could not. The study has found that predicted Ds/Do and correlate with greenhouse gas fluxes even when the air-filled porosity and the total porosity from which they are predicted did not. We have also showed that Ds/Do and can be predicted quickly from routine measurements of soil water and air and existing diffusivity models found in the literature. Agricultural practices do seriously impact greenhouse gases emissions as showed by the effect of mechanized tillage operations on soil physical properties and greenhouse gas fluxes in a corn and soybean fields. In fact, our results showed that tractor compaction increased soil resistance to penetration, water, bulk density and pore tortuosity while reducing air-filled porosity, total pore space and the soil gas diffusion coefficient. Changes in soil properties resulted in increased CO2, NO and N2O emissions. Finally, our results also confirmed that greenhouse gas fluxes vary tremendously in space and time. As estimates of greenhouse gas emissions are influenced by the data processing approach, differences between the different calculation approaches leads to uncertainty. Thus, techniques for developing better estimates are needed. We have showed that Geographic Information Systems (GIS), Global Positioning System (GPS), computer mapping and geo-statistics are technologies that can be used to better understand systems containing large amounts of spatial and temporal variability. Our GIS-based approach for quantifying CO2, CH4 and N2O fluxes from soil in agricultural fields showed that estimating (extrapolating) total greenhouse gas fluxes using the “standard” approach – multiplying the average flux value by the total field area – results in biased predictions of field total greenhouse gases emissions. In contrast, the GIS-based approach we developed produces an interpolated map portraying the spatial distribution of gas fluxes across the field from point measurements and later process the interpolated map produced to determine flux zones. Furthermore, processing, classification and modeling enables the computation of field total fluxes as the sum of fluxes in different zones, therefore taking into account the spatial variability of greenhouse gas fluxes.

- Description: Mark-recapture models do not distinguish how ‘‘deaths’’ accrue to marked animals in the population. If animals lose their tags, then recaptures will be fewer than expected and estimates of survival will be underestimated (Arnason and Mills, 1981; McDonald et al., 2003). Similarly, if the non-reporting rate is unknown and assumed to be negligible, as is the case in some tagging studies (e.g. Cliff et al., 1996, for white sharks Carcharodon carcharias), the probability of capture can be underestimated. The effects of both these problems, inherent in cooperative tagging programmes, lead to too few tagged fish being recovered, with a positive bias on the estimation of population size. These effects are most pronounced when capture probability is low and fewer tags are available for recapture (McDonald et al., 2003).

- Description: South African inland fisheries are poorly developed and their contribution to near-shore communities is poorly understood. This study is the first comprehensive assessment of recreational and subsistence angling undertaken in an inland fishery in South Africa. The study was conducted on the 360 km2 Lake Gariep, South Africa’s largest freshwater reservoir. A total of 508 anglers were interviewed between February 2007 and January 2008. Of those interviewed, 67% were subsistence anglers and 33% recreational anglers. Catch per unit effort (CPUE) did not differ significantly between sectors. CPUE fluctuated seasonally, ranging between 0.37 (95% CI= 0.26 to 0.51) kg·angler-1·h-1 in winter and 0.88 (0.67 to 1.17) kg·angler- 1·h-1 in summer. The duration of a fishing day ranged from 5.99 (5.24 to 6.74) h in mid-winter to 7.26 (6.88 to 7.63) h in early summer. Expected end-of-day catch (CPUE × fishing-trip duration) ranged from 2.2 to 6.4 kg·angler-1·d-1 depending on the season. The number of anglers ranged from 22 (8 to 53) anglers·d-1 in June/July to 74 (25 to 176) anglers·d-1 in April. Total annual catch from the roving creel survey was estimated at 71.4 (57.4 to 91.4) t·yr-1. Another 7.5 t∙yr-1 were landed during recreational angling competitions. The resultant total catch divided by the lakeshore population equated to a per capita fish supply of 11.1 kg·yr-1. More than 70% of the catch was the alien invasive carp Cyprinus carpio and there was no evidence of overfishing. The fish resource of Lake Gariep is of significant recreational and subsistence value. As a result of the low fish price (ZAR5.72 ± 2.60·kg-1) subsistence fishing was considered a low-revenue activity that mainly augmented food security in lakeshore communities. The relatively high CPUE indicated that the fishery may be an important safety-net during periods when alternate sources of livelihoods are limited. Consequently, we recommend that the importance of angling to local communities needs to be taken into account when planning fisheries development and developing an inland fisheries policy

The ongoing shortage of space, and the need to accommodate evolving patterns of use, common to most academic libraries, fuelled the engine which drove the Rhodes Library on its circuitous journey from humble lodgings in a single room in the old Drostdy Building more than a hundred years ago, to its final destination in the imposing position it occupies today.

- Description: During the era of discrimination and disparity in Southern Africa, racial inequality silenced many black writers. It was the white authors that dominated the literary environment presenting their biased views on social and political concerns; the black authors standpoints were seen as unimportant and they were deemed inferior to the white authors. Consequently, it was particularly difficult for black writers to voice their experiences of living in a society riddled with oppression, prejudice and unequal opportunities. The purpose of this study is to critically compare selected texts by African authors Doris Lessing and Bessie Head, which depict the political and social struggles within Southern African society during the era of unequal opportunities. Lessing and Head’s works present incidents of life experiences in Southern Africa from two contrasting viewpoints. The selected texts explored are: The Grass is Singing and “The Old Chief Mshlanga” by Doris Lessing, a white author, in contrast and comparison to the texts: A Question of Power and “The Collector of Treasures” by Bessie Head, a coloured author. The research for this thesis is conducted from an ethnic literary perspective with careful consideration to critical race theory and cultural studies. From this perspective, the focus of the study is on the struggles that affected both the victim and perpetrator during the apartheid era as well as on the idea that those in power determined what was deemed acceptable and unacceptable, behaviourally and ideologically. Specifically, the plight experienced by the female characters living in a patriarchal society, and the segregation and racial inequality faced by the characters of colour is explored by analysing these characters’ influences, pressures and societal manipulations and constraints in the texts. Thus, this study will provide a more in-depth understanding of Southern African society during the apartheid era and the strategic use of literature to spotlight the subjugation and disparity.

- Description: This study addresses the problem of abject rural poverty in the post-apartheid South Africa with specific reference to the Amathole Rural District (ARD) in the Eastern Cape Province (the poorest province in the country). Abject poverty is conceptualized as inability to meet the basic human needs such as food, water, shelter and clothes. The study is premised in the revisionist trajectory of rural economic development, which regards agriculture as the ‘engine’ for rural development. The thesis addressed the following issues on rural poverty reduction in the ARD; the efficacy of rural agriculture in rural poverty reduction, value-adding to rural farm produce, support that is required and social factors that may affect the residents’ ability to fight poverty through agriculture? The thesis adopted the concurrent transformative mixed research methodology; and data were collected from a purposive sample of 138 respondents using unstructured interviews and semi-structured questionnaires. Data were collected with the help of research assistance. The study established that the ARD residents were keen to fight abject poverty through rural agriculture but were constrained by the lack of arable land, financial resources, technological support, corruption and HIV/AIDs. In view of the above findings, the thesis concluded that deep collaboration and participation of strategic partners such as government, the rural residents, NGOs and the business sector is essential in the implementation of pro-poor strategies in the ARD. The thesis also called for further research into the following areas that have a direct influence on the efficacy of rural agriculture on the ARD’s development; ICT and development, the rural residents’ attitude towards savings and on the political economy of cooperative ventures in rural agriculture. The thesis also encouraged further research to establish new linkages and roles of the following pertinent partners in ARD’s development; government, the rural residents, NGOs and the business sector. , Thesis (PhD) -- Faculty of Management and Commerce, 2010

- Description: This study addresses the problem of abject rural poverty in the post-apartheid South Africa with specific reference to the Amathole Rural District (ARD) in the Eastern Cape Province (the poorest province in the country). Abject poverty is conceptualized as inability to meet the basic human needs such as food, water, shelter and clothes. The study is premised in the revisionist trajectory of rural economic development, which regards agriculture as the ‘engine’ for rural development. The thesis addressed the following issues on rural poverty reduction in the ARD; the efficacy of rural agriculture in rural poverty reduction, value-adding to rural farm produce, support that is required and social factors that may affect the residents’ ability to fight poverty through agriculture? The thesis adopted the concurrent transformative mixed research methodology; and data were collected from a purposive sample of 138 respondents using unstructured interviews and semi-structured questionnaires. Data were collected with the help of research assistance. The study established that the ARD residents were keen to fight abject poverty through rural agriculture but were constrained by the lack of arable land, financial resources, technological support, corruption and HIV/AIDs. In view of the above findings, the thesis concluded that deep collaboration and participation of strategic partners such as government, the rural residents, NGOs and the business sector is essential in the implementation of pro-poor strategies in the ARD. The thesis also called for further research into the following areas that have a direct influence on the efficacy of rural agriculture on the ARD’s development; ICT and development, the rural residents’ attitude towards savings and on the political economy of cooperative ventures in rural agriculture. The thesis also encouraged further research to establish new linkages and roles of the following pertinent partners in ARD’s development; government, the rural residents, NGOs and the business sector. , Thesis (PhD) -- Faculty of Management and Commerce, 2010

- Description: The reaction of the potentially tridentate Schiff-base chelate Hhaep [Haep = N’-(1- (2-hydroxyphenyl)ethylidene)benzohydrazide] with [ReCl3(benzil)(PPh3)] and trans-[ReOCl3(PPh3)2] produced the neutral oxorhenium(V) complexes cis- [ReOCl2(mep)] [Hmep = 2-(1-iminoethyl)phenol] and cis-[ReOCI2(meb)(PPh3)] [Hmeb = N’-(propan-2-ylidene)benzohydrazide] in ethanol and acetone respectively. In both reactions the Hhaep molecule cleaves to give different coordinated bidentate NO-donor chelates coordinated to the rhenium(V) centers. The X-ray studies reveal that mep is present as a bidentate, monoanionic Schiffbase coordinating through the neutral imino nitrogen and the deprotonated phenolate oxygen in cis-[ReOCl2(mep)]. The bond distances and angles in cis- [ReOCI2(meb)(PPh3)] confirm that meb coordinates to the metal in the enolate form. The distorted octahedral complex fac-[ReCl3(dpa)(PPh3)] was prepared by the reaction of trans-[ReCl3(MeCN)(PPh3)2] with a twofold molar excess of dpa in acetonitrile under a nitrogen atmosphere. The compound dpa.HCl.2H2O was obtained as a by-product in the reaction of dpa with trans-[ReCI3(MeCN)(PPh3)2] in acetonitrile. The reaction of trans-[ReCl3(MeCN)(PPh3)2] with a twofold molar excess of 6- amino-3-methyl-1-phenyl-4-azahept-2-ene-1-one (Hamp) in acetonitrile led to the isolation of cis-[ReCl2(bat)(PPh3)2]. On complexation to the metal center Hamp decomposed to give the coordinated benzoylacetone (bat). Bat is present as a monoanionic bidentate chelate. The complexes [ReVOCI(had)] and [ReIVCl(had)(PPh3)](ReO4) were prepared from the reaction of trans-[ReCl3(MeCN)(PPh3)2] with N,N-bis((2-hydroxybenzyl)-2- aminoethyl)dimethylamine (H2had) in ethanol under various reaction conditions. The treatment of [ReCl3(benzil)(PPh3)] with 2-[((2- pyridinylmethyl)amino)methyl]phenol (Hham) in a 2:1 molar ratio in acetonitrile led to the isolation of the hydrogen-bonded dimer [ReOCl2(ham)]2. The distorted octahedral complex [ReOCl(hap)] [H2hap = N,N-bis(2- hydroxybenzyl)aminomethylpyridine] was prepared from the reaction of trans- [ReCl3(MeCN)(PPh3)2] with a twofold molar excess of H2hap in acetonitrile. The X-ray crystal structure analysis shows that the chloride is coordinated trans to the tripodal tertiary amino nitrogen, with a phenolate oxygen trans to the oxo oxygen.

- Description: Community-based natural resource management (CBNRM) has been a pervasive paradigm in conservation circles for three decades. Despite many potentially attractive attributes it has been extensively critiqued from both ecological and sociological perspectives with respect to theory and practice (for example Leach et al. 1999; Berkes 2004; Fabricius et al. 2004; Blaikie 2006). Nonetheless, many successful examples exist, although an equal number have seemingly not met expectations. Is this because of poor implementation or rather a generally flawed model? If the criteria and conditions for success are so onerous that relatively few projects or situations are likely to qualify, what then is the value of the model? The questions thus become: how and what can we learn from the past theory and practice to develop a new generation of flexible, locally responsive and implementable CBNRM models, and what are likely to be the attributes of such models?

- Description: Using the SAFRING database and the Underhill-Zucchini model of primary moult, we analysed the timing of wing moult in Southern Red Bishops Euplectes orix in relation to sex and geographical region. Birds from the winter rainfall region in the south-western sector of the Western Cape start the annual moult more than two months before any other population, but there were no significant differences in starting date within the summer rainfall region. There were striking differences in the estimates of moult duration (62–114 d), which did not follow a consistent pattern in relation to sex or geography; annual variation within a region may be an additional factor. Throughout southern Africa, both sexes showed a trend for longer-winged birds to take more time to complete their moult. We suggest that sex, geographical area and possible annual environmental variations may all influence the timing of moult in local populations. In this sexually dimorphic species, males are consistently longer-winged and heavier than females.

- Description: As chronic illnesses continue to be a burden in today’s organisations, it remains a very crucial call for management to find ways to eradicate the associated organisational problems. While people of all ages are affected by chronic illnesses, there is a higher risk of the elderly developing chronic diseases. However, as much as chronic illnesses are inevitable among employees, there should be ways at least to curb negative social and goal achievement impact which they bring in organisations. In this regard, a survey of 80 employees was conducted to examine the relationship between employees' knowledge about, contact with, and attitudes towards their co-employees with chronic illnesses (CI). Results indicated that employees' knowledge about and contact with individuals diagnosed with chronic illnesses were significantly related to better attitudes toward this population. The findings also revealed that knowledge was related to positive attitudes among employees who had more personal contact with individuals with Chronic illnesses (CI) and such findings indicate the importance of exposing employees to information about chronic illnesses and direct practice experience with individuals who have these illnesses. To be noted also is that 39% of the respondents preferred to be exposed to health bulletins and magazines; 18% of the respondents preferred the help of health workers and about a third (30%) favoured brochures, posters and printed materials such as flyers. Managerial implications for employees with chronic illness are discussed

- Description: During the moult of primary wing feathers in birds it is likely that new feather material is being produced at an approximately constant rate if the energetic requirements of the birds are met. In moult regression analyses it is, therefore, desirable to transform moult measurements into a variable based on the amount of new feather material produced because of its linear properties. This can be achieved if the mass of each primary feather is known, and used as a weighting factor in a moult index. These primary feather masses would have to be known for every species being analysed. As an alternative, it is here tested if feather mass indices may be sufficient replacements for species-specific feather masses. Thirty-five species of birds with known primary feather masses were divided into four wing-shape groups, and a feather mass index was built for each group. Within each group, comparisons were made between estimates of moult parameters using the moult index with those using the known primary feather masses. Within groups there were no significant differences between any of the moult estimates.

- Description: Development is a critical aspect of individuals, groups, communities or nations. Community development is even more critical aspect of development as it purportedly leads to self reliance. Huge amounts of funds, time, and resources, just but to mention a few have been continuously channeled towards communities over time in a bid to facilitate community development. Unfortunately, results of such actions and interventions by NGOs, governments and a host of development agencies have so far largely proved elusive. Contrary to NGO expectations and popular opinion, target communities continuously demand, request and expect increased direct support from development agencies. Solving acute community problems and challenges, the focus of most NGO development interventions has been less successful. Target problems have largely graduated and turned to chronic levels. All this is unfortunately worsening against the background of increased donor and NGO support. Deteriorating and widening community challenges are also taking place against general claims by NGOs to the application of community development ideals in communities as a successful development alternative. Contrastingly, rather than being self reliant, communities have become more dependent on donors. In addition, NGO target communities continue to grapple with short-lived changes, limited participation by the majority, reversal of past successes and dwindling self representation and reliance. Inequalities have widened. This is to the detriment of ongoing NGO claims and efforts at promoting community development.

- Description: This work reports the electrocatalysis of bisphenol A on Ni(II) tetraamino metallophthalocyanine (NiTAPc) polymer modified gold electrode containing Ni–O–Ni bridges (represented as Ni(OH)TAPc). The Ni(II)TAPc films were electro-transformed in 0.1 mol L−1 NaOH aqueous solution to form ‘O–Ni–O oxo bridges’, forming poly-n-Ni(OH)TAPc (where n is the number of polymerising scans). poly-30-Ni(OH)TAPc, poly-50-Ni(OH)TAPc, poly-70-Ni(OH)TAPc and poly-90-Ni(OH)TAPc films were investigated. The polymeric films were characterised by electrochemical impedance spectroscopy and the charge transfer resistance (RCT) values increased with film thickness. The best catalytic activity for the detection of bisphenol A was on poly-70-Ni(OH)TAPc. Electrode resistance to passivation improved with polymer thickness. The electrocatalytic behaviour of bisphenol A was compared to that of p-nitrophenol in terms of electrode passivation and regeneration. The latter was found to passivate the electrode less than the former. The poly-70-Ni(OH)TAPc modified electrode could reliably detect bisphenol A in a concentration range of 7 × 10−4 to 3 × 10−2 mol L−1 with a limit of detection of 3.68 × 10−9 mol L−1. The sensitivity was 3.26 × 10−4 A mol−1 L cm−2.

- Description: The reproductive and recruitment characteristics of moggel, Labeo umbratus, populations were examined in four small South African reservoirs. Reproduction, characterised by an extended spawning season, high fecundity, short incubation time and rapid larval development, appears to be ideally suited to the highly variable environment of small reservoirs. Evidence suggested that L. umbratus spawns in the reservoirs. In two reservoirs where samples were conducted monthly, GSI (gonado-somatic index) was positively correlated with both water temperature and day length, whilst the CPUE (catch per unit effort) of juveniles was not related to any environmental variable. The success of moggel spawning appeared to increase when there was early spring and consistent summer rainfall.
