- Description: The facile electro-oxidation of diuron occurred at a glassy carbon electrode (GCE) modified with polymerized nickel tetraamino-phthalocyanine (NiTAPc), containing O–Ni–O bridges represented as poly-Ni(OH)TAPc-GCE. The oxidation of diuron occurred at a potential which is 60 mV less than that of poly-NiTAPc (without O–Ni–O bridges) and was accompanied by enhanced catalytic currents. The catalytic rate constant and the diffusion constant were found to be 5.91 × 102 mol−1 L s−1 and 6.43 × 10−6 cm2 s−1, respectively. The linear concentration range of diuron was 3.0 × 10−5 to 3.5 × 10−4 mol L−1 with a limit of detection (LOD) of 3.3 × 10−7 mol L−1 (3δ notation) and a sensitivity of 12.9 A mol−1 L cm−2.

- Description: This study examines the perceived scarcity of household water service delivery in the city of Kwekwe under the Midlands province of Zimbabwe. Kwekwe Municipality appears to be characterized by an erratic supply of clean water for household use. The city of Kwekwe has experienced an unreliable domestic water service delivery system since the beginning of this millennium. This study aims to investigate the causes of the problem, its extent, impact and what could be done to mitigate the problem. The study employs interviews, questionnaires, observations and document analyses to establish that population growth, ageing equipment, a lack of foreign currency and local funding, as well as a lack of expertise and of political will have contributed to the poor domestic water supply in the city of Kwekwe. The city of Kwekwe needs to commit itself to improving the current situation by involving the community, constructing more storage facilities, and by putting monitoring and evaluation mechanisms in place. The research design took the form of a case study of Kwekwe Municipality. A mixture of qualitative and quantitative research designs were used in this study. The qualitative/interpretivist approach was more dominant, allowing some overlapping with the quantitative/positivist paradigm whenever this was considered reasonable. The study sample consisted of a conveniently assembled sample of 120 respondents. The target population for the study comprised of 110 residents of Kwekwe urban and 10 Kwekwe City Municipality Water Authorities from the Works Department. This study focuses on the 4 residential areas of Kwekwe Municipality. The data collection instruments include questionnaires and focus group interviews. Electronically recorded, in-depth interviews were held with the water authorities and the consumers to establish their perceptions on the best practice of the water service delivery system in Zimbabwe. The data collection tools contained a preliminary section on the biological data of the respondents. All data was subjected to either qualitative or quantitative analysis techniques in order to strike a balance between the structured survey instruments and the anecdotes of the respondents. Quantitative data was analyzed using a Statistical Package for Social Sciences (SPSS), while qualitative data was subjected to document analysis which entailed classifying the data, extracting themes, identifying patterns, tallying and quantifying responses and making generalizations out of these patterns. This implies that the research methodology focused on the method, tools and techniques used to assist in achieving the objectives of the study and answering the research questions that the research seeks to address. The term research methodology is used, in this study, to refer to the philosophical assumptions, values, and theories which inform and underpin the way in which a particular research method is used. In this study, the case study research design was used as the operational framework for data gathering. The case study research method is essentially grounded in the interpretive research paradigm. To this end, the study sought the perceptions of both the consumers and the water authorities. The major finding of the study is that the ability of Kwekwe Municipality to provide household water service delivery to its consumers is slightly below average. However, there was a slight improvement in the household water service delivery but consumers are still remaining dissatisfied. Another finding, related to this one, was that the electricity deficiency cost the efficacy of Kwekwe Municipality in its provision of household water service delivery. The study proposes that more studies which seek to interrogate the domestic water service delivery system of the Zimbabwean Municipalities should be embarked upon by the state. The study also recommends that service delivery training programmes be implemented in order to enhance the competence of the water authorities. Furthermore, the study suggests that consumers be placed at the center of household water debates when policies, rules and regulations of the water service delivery system are formulated. Finally, the study implores that municipalities need to have their own reserves and generators for emergency cases during electricity power cuts. It is imperative that the water reservoirs constantly hold 4 days‟ worth of water capacity. The municipality of Kwekwe must refurbish the entire water reticulation system. Municipalities must carry out an audit of water meter readings and also confirm that all water meters are functional. Manpower to read the correct meter reading should be increased in number and must have reliable transport. , Thesis (PhD) -- Faculty of Management and Commerce, 2010

- Description: In this study an analysis of the long-term equilibrium relationship between inflation, selected macroeconomic variables and the Zimbabwe stock market (represented by market capitalization) is explored. Using stock market capitalization as a proxy for stock market performance is important for an investigator since it can capture movements in the whole market. The link between stock market performance and macroeconomic variables in particular inflation is well-documented in the literature. However, a void in the literature relates to examining the cointegration between hyperinflation and stock market performance. Although hyperinflation is nothing more than inflation at high rates, clarity on this point is necessary because of the seemingly unclear nature of the relationship in the literature. Inflation has mostly been documented as negatively impacting on financial markets. This is not so clear when it comes to hyperinflation. The Zimbabwean stock market has performed well during the high inflation period. This then raises the question: Does hyperinflation stimulate the growth of the stock market? The analysis is undertaken by employing cointegration and vector error correction modeling approach using quarterly data for the period 1980-2007 Our results show among others, that hyperinflation has impacted negatively on the growth of the stock market in Zimbabwe. However, other driving factors such as foreign direct investment and relatively high bank lending rates may have fuelled the observed growth in the stock market during the period of study. , Thesis (MCom) -- Faculty of Management and Commerce, 2010

- Description: Inflation is one of the most important factors for gauging the health of the economy. For production, employment and trade to take place, it is crucial that inflation be low and stable. This study analyses the implications of a currency board system in a hyperinflationary economy, using quarterly Zimbabwean data covering the period 1995 to 2008.An empirical model linking inflation to its identified theoretical determinants is specified. The study employs a cointegration and a vector error correction (VEC) modeling, to provide robust long run and short run dynamic effects of hyper inflation on the economy. The empirical findings reveal a strong significant relationship between inflation and government deficit, expected inflation, money supply growth and the exchange rate. These results corroborate the theoretical predictions and the previous findings that most hyperinflations are deficit-induced. The study thus suggests an implementation of a currency board arrangement for Zimbabwe to eradicate hyperinflation based on its link with exchange rate, money supply and government deficit. A currency board restrains the tendency by most central banks to create money to finance government deficits, and reduces expectations of rising inflation through its instantaneous credibility in reducing inflation. , Thesis (MCom) -- Faculty of Management and Commerce, 2010

- Description: This study seeks to address the adoption of Integrated Tertiary Software (ITS), ease of use of ITS and continuous usage in Human Resources Departments. The focus of this research project is User Acceptance and Continued Use of ITS within the HR Department - the case of Fort Hare University. The University is a multi - campus operation and the use of paper systems is extremely difficult. The University made a decision to invest in ITS with the objective of improving effectiveness and efficiency of services. The nature of the problem is that ITS is partially used and it is necessary to further explore the specific influence of technological and environmental factors that may change the user’s acceptance and use of this IT System. The nature of this study is Qualitative and follows an Interpretive Approach. The Research Instrument used is an in-depth questionnaire distributed and responded to by all HR Professionals at the UFH. Recommendations based on findings will be used to design the Critical Success Factors (CSFs) for the Adoption of IT Systems by HR Professionals in order to enhance efficacy at the University of Fort Hare. The CSFs can be generalized to other settings and were identified for the UFH HR Department to include. , Thesis (MCom) -- Faculty of Management and Commerce , 2010

The effects of open-shell metals (Ni(II), Pd(II) and Pt(II)) on the photophysical and photochemical properties of the phthalocyanine ligands were investigated. Palladium and platinum improved the triplet quantum yield and singlet oxygen generation capacities of the unmetalated phthalocyanines (3a–3e) making their complexes candidates for further investigation in photocatalysis. Ni(II)Pc analogues gave poor results compared with their Pd(II)Pc and Pt(II)Pc counterparts.

- Description: In the context of increasing national and global environmental challenges and their implications for the working world, new ethics and practices are being introduced into workplaces that take better account of socio-ecological relations. Little is understood, however, about the nature of ethics-oriented workplace learning. Drawing on Cultural Historical Activity Theory (CHAT), which enables historically and contextually situated relational perspectives to emerge, this paper explores contradictions in the activity systems of two young environmental education learner-practitioners struggling to engage with the ethical dimensions of their professional work and the professional development course they are studying. The study focuses in particular on the environmental values and ethics component of their course – a year-long Learnership in Environmental Education, Training and Development Practices (EETDP). The paper reflects how tensions and contradictions within and between the interacting activity systems of the workplace, the course, and its regulating qualifications authority influence the teaching and learning of the environmental ethics component of the course. Ethics-oriented teaching and learning processes are found to be strongly influenced by the ‘rules’ and ‘mediating tools’ of these interacting systems, but these are often at odds with the ethical perspectives, socio-cultural context and skills of the ‘subject’ and ‘community’. These systemic contradictions can be more fully understood when their cultural and historical origins are made explicit. The analytical process has led to a more nuanced understanding of ethics-oriented teaching and learning in a workplace-based course, and has revealed several areas needing more careful research (particularly the area of environmental discourses) and the explicit and implicit language of ethics.

- Description: Particles suspended in water attenuate the light that passes through it via absorption or scattering (Utne-Palm 2002). For example, whereas algae absorb specific wavelengths of light necessary for photosynthesis, inorganic suspensoids tend to scatter light (Radke and Gaupisch 2005). This results in lowered ambient light levels and reduces the visual acuity of aquatic organisms. From a fish’s perspective, an increase in water turbidity has the potential to alter visually-mediated reproductive behaviours (Järvenpää and Lindström 2004), predator avoidance (Meager et al. 2006) and foraging success negatively (Utne-Palm 2002, Rowe et al. 2003, Sweka and Hartman 2003, Stuart-Smith et al. 2004). The foraging success of various fish species was affected by increased turbidity through decreasing predator–prey encounter rates (Sweka and Hartman 2003) and through decreasing visual acuity whereby the distance at which prey are visually detected is reduced (Utne-Palm 2002).

For example, whereas algae absorb specific wavelengths of light necessary for photosynthesis, inorganic suspensoids tend to scatter light (Radke and Gaupisch 2005). This results in lowered ambient light levels and reduces the visual acuity of aquatic organisms. From a fish’s perspective, an increase in water turbidity has the potential to alter visually-mediated reproductive behaviours (Järvenpää and Lindström 2004), predator avoidance (Meager et al. 2006) and foraging success negatively (Utne-Palm 2002, Rowe et al. 2003, Sweka and Hartman 2003, Stuart-Smith et al. 2004). The foraging success of various fish species was affected by increased turbidity through decreasing predator–prey encounter rates (Sweka and Hartman 2003) and through decreasing visual acuity whereby the distance at which prey are visually detected is reduced (Utne-Palm 2002).

- Description: Pre-print , Many universities and colleges around the world have done extensive surveys of their campus built heritage resources. A detailed description and accounting of a campus's built heritage, landscape heritage and archaeology, are often used for historic preservation planning, and sustaining built culture is also an important aspect of campus master planning of future buildings. Such institutions of higher education have deep historical roots, in Europe it is not uncommon for buildings to be dated prior to the sixteenth century. In countries where European colonies were established, institutions of higher education often date to the eighteenth and early nineteenth centuries. Once students have arrived at their chosen campus, however, except for perhaps the first week orientation rituals, do the students actually develop ties to their campus built heritage? This research investigates the knowledge students possess of their respective campus built heritage and the importance of built heritage as a legacy to them. Two institutions are included in this study in an effort of draw comparative assessments. A student questionnaire was administered at Rhodes University in South Africa and St. Mary's College of Maryland in the United States during April 2008. Results indicate students on both campuses place positive intrinsic value on their respective campus built heritage. Just over half (52%) of Rhodes students and about 68% of St. Mary's students were willing to pay some positive amount to protect campus built heritage. Empirical probit model results combining the data from both institutions found that current student knowledge of their respective campus built heritage did not positively relate to the value they place on preservation, even though the visual identity was significant for students and influenced their decision to attend the particular institution. The lack of significance regarding a racial variable coefficient estimate suggests that the use of an institution's visual identity in terms of built heritage may have important marketing implications, particularly in cases where universities or colleges are trying to attract students from more diverse backgrounds. We found no significant relationships between willingness to pay to preserve an institution's built heritage and the demographic variables included in our empirical model. Fundraising data analysis includes positive willingness to pay for conserving built heritage, yet funding for new construction was not significant.

- Description: Dentex macrophthalmus is a small, commercially important sparid fish that is abundant in the deeper waters (range 50–500 m) of the Mediterranean Sea (Trunov 1970), the North-West African shelf (Goode and Bean 1896, Fowler 1936), including the Cape Verde and Canary Islands, and the south-eastern Atlantic from the Equator to just south of Lüderitz (27°40′ S) (Trunov 1970). Because of its high abundance, it is of considerable economic importance and is captured in large numbers in both artisanal and commercial fisheries in many countries. Although it is the most important artisanal species along the entire Angolan coast, it is most abundant in the southern region (Kilongo et al. 2007). Despite its economic importance in Angola and elsewhere, relatively little is known on its abundance, fisheries and biology.

- 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.

- Description: The diet and growth of sharptooth catfish, Clarias gariepinus, in an oligotrophic system (Kat River Reservoir, Eastern Cape, South Africa) were compared to those in a eutrophic system (Laing Reservoir, Eastern Cape) to determine if the trophic status of a waterbody had an effect on the growth rate of the species. In order of importance, the diet of catfish in Kat River Reservoir consisted of fish, insects, zooplankton, plant material and other items, while the diet of catfish in Laing Reservoir consisted of fish, plant material, zooplankton, other vertebrates and insects. The diets of catfish in the two reservoirs had a similarity index of 68.1% and there was no significant difference in their nutritional value. Fish prey was the most important dietary component in both reservoirs. Temperature regime and zooplankton and zoobenthos density were similar in both systems. However, fish prey density was significantly higher in the eutrophic Laing Reservoir and catfish grew significantly faster in that system. The slower growth rate in Kat River Reservoir was attributed to the higher energy costs associated with the capture of fish prey, which was less abundant than in Laing Reservoir. Trophic status therefore had an indirect effect on catfish growth by influencing the availability of fish prey.

- Description: This article discusses how the gendering of activity by boys coincides with, contests or recreates constructions of hegemonic masculinity in the context of South Africa. The study used a qualitative methodology including a series of three focus groups with 14–16 year-old boys across six different schools in the Western Cape, South Africa. A discursive analysis in which particular attention was paid to how participants construct their masculinity in relation to what they may or may not do as boys/men was conducted. The findings foreground how articulations of masculinity by boys are characterised by efforts to gender activity in the process of, amongst other things, counter blushing—meaning not to be regarded as girl-like or a moffie, or other derogatory notions that do not fit with hegemonic masculinity in a particular context. However, resistances and alternative views on what boys/men can and cannot do also emerged, highlighting the contested nature of current constructions of masculinity among young people in South Africa.

- Description: In the academic literature, civil society is often conceptualized in terms of objectifications and subject—object dichotomies. This is the case with regard to both social movements and non-governmental organizations. This article seeks to transcend such argumentation by providing ‘thick descriptions’ of the agency of farm workers and civil society in the context of land reform in contemporary Zimbabwe. We examine a land-based social movement (and the role of farm workers within it) and the involvement of a particular non-governmental organization in farm worker livelihoods. On this basis, we offer a re-formulation of civil society as a social field marked by ambivalences and tensions.

- Description: This paper reports on the farming and trade of lesser known crops, here termed African indigenous vegetables (AIVs), in the Durban metropole. Most households grow AIVs, and collect them from the wild, primarily for home consumption. Modal income from sale was approximately R30 per month per farmer, most of whom were middle-aged to elderly females, with limited education, who had been cultivating AIVs here for many years. The main constraints to greater sales were deemed to be low market demand and adverse climate. The commonest AIVs grown were pumpkin leaves, taro and amaranth. Although most farmers sold very little, there is a thriving retail trade in AIVs. Generally, retailers were females, but younger and more educated than the farmers. The majority viewed retailing as a full-time occupation. Modal income for retailers was R450 per month, but included non-AIV produce. Most of the traders thought there was insufficient market demand for AIVs.
