Factors influencing wetland distribution and structure, including ecosystem function of ephemeral wetlands, in Nelson Mandela Bay Municipality (NMBM), South Africa

Melly, Brigitte Leigh, Gama, Phumelele T January 2016 (has links)
The Nelson Mandela Bay Municipality (NMBM) is a semi-arid area along the southern coastline of South Africa (SA). Until recently, there was no systematic approach to research on wetland systems in the NMBM. The systematic identification of wetlands was made more difficult by the relatively large number of small, ephemeral systems that can be difficult to delineate. This has meant that fundamental knowledge on wetland distribution, structure and function has been limited and, consequently, management and conservation strategies have been based on knowledge on systems from other regions of the country. Environmental processes occur at different spatial and temporal scales. These processes have an effect on the abiotic factors and biotic structure of wetlands, resulting in inherently complex systems. The location of the NMBM provides a good study area to research some of these environmental and biological attributes at different spatial scales, due to the variability in the underlying geology, geomorphology, vegetation types and the spatial and temporal variability in rainfall, within a relatively small area of 1951 km2. Thus, the aim of this study was to determine the factors influencing wetland distribution, structure and ecosystem functioning within the NMBM. The first Research Objective of work presented here was to identify wetlands using visual interpretation of aerial photographs. A total of 1712 wetlands were identified within the NMBM using aerial photographs, covering an area of 17.88 km2 (Chapter 5). The majority of these wetlands were depressions, seeps and wetland flats. Valley bottom wetlands (channelled and unchannelled) and floodplain wetlands were also identified. A range of wetland sizes was recorded, with 86% of the wetlands being less than 1 ha in size and the largest natural wetland being a floodplain wetland of 57 ha, located south of the Swartkops River. The identified wetlands were used to create a wetland occurrence model using logistic regression (LR) techniques (Chapter 5), in accordance with Objective 2 of the study. An accuracy of 66% was obtained, which was considered acceptable for a semi-arid climate with a relatively high degree of spatial and temporal rainfall variability. The model also highlighted several key environmental variables that are associated with wetland occurrence and distribution at various spatial scales. Some of the important variables included precipitation, evapotranspiration, temperature, flow accumulation and groundwater occurrence. Wetland distribution patterns were described in Chapter 6. Spatial statistics were used to identify whether wetlands are clustered and, therefore, form mosaics within the surrounding landscape (Objective 3). Systems were found to be highly clustered, with 43% of wetlands located within 200 m of another system. Clustering and wetland presence was especially prominent in the southern portion of the Municipality, which is also associated with a higher mean annual precipitation. Smaller wetlands were also significantly more clustered than larger systems (Average Nearest Neighbour statistic, p-value < 0.0001). Average distances also significantly varied according to HGM type, with depressions being the most geographically isolated wetland type compared to the other HGM types. Overall, distances between wetlands indicated good proximal connectivity. Potentially vulnerable areas associated with wetland systems were identified successfully using landscape variables, in accordance with Objective 4. These variables were: land cover, slope gradient, flow accumulation, APAN evaporation, mean annual precipitation (MAP) and annual heat units. The existing Critical Biodiversity Network was also used in connection with these variables to further identify potentially vulnerable areas. The abiotic and biotic characteristics were decribed for three hydrogeomorphic (HGM) types at a total of 46 wetland sites (Chapter 7), as per Objective 5. Depressions, seeps and wetland flats were sampled across the different geological, vegetation and rainfall zones within the NMBM. The wetland sites were delineated up to Level 6 of the Classification System used in SA, and the various abiotic and biotic characteristics of these systems were defined. A total of 307 plant, 144 aquatic macroinvertebrate and 10 tadpole species were identified. Of these species, over 90 species were Eastern Cape and SA endemic species, as well as three threatened species on the IUCN Red List. Multivariate analyses (including Bray-Curtis similarity resemblance analyses, distance-based redundancy analyses, SIMPER analyses and BIOENV analysis in Primer), together with environmental data, were used to define community structure at an HGM level, in accordance with Objective 5. The importance of the spatial scale of the environmental data used to define plant and macroinvertebrate community structure was described in Chapter 7, to address Objective 6. The results showed that both broad-scale and site-level characteristics were important in distinguishing community structure within the HGM types that superseded general location, the sample timing or the stage of inundation. These results also indicated that a combination of both landscape and site-level data are important in defining the community structure in the various HGM types. Some of the important environmental variables that explained some of species assemblages were similar to those in the wetland occurrence model (Chapter 5), with some additional hydrological and soil physico-chemical parameters (e.g. soil electrical conductivity, soil pH, and surface and subsurface water nutrients). These significant variables indicate the complex, multi-scalar role of environmental attributes on wetland distribution, structure and function.

The health and injury risks faced by emergency medical workers in the Nelson Mandela Bay Municipality

Yeki, Zandisile Rupert January 2015 (has links)
This study investigated the health and injury risks faced by emergency medical workers in the Nelson Mandela Metropolitan Municipality. The aim of the study was to establish the emergency worker`s awareness, level of knowledge and attitude to practices of health and safety issues. The study sample consisted of eighty (80) emergency medical workers stationed in Port Elizabeth and Uitenhage. A self- administered questionnaire was developed and used in an empirical survey to collect data from the respondents on information such as health and safety knowledge, behavior, experiences, attitudes, beliefs and opinions in their workplace. The results of the study indicated that 90% of the workers experienced all occupational hazards identified in the questionnaire. Percutaneous injuries were found to be at 48%, PTSD was rated at 40% due to horrific accidents and incidents complicated by violent threats and armed robberies with emergency workers being victims. Musculoskeletal injuries were found to be very common. Ordinary stress was caused by dissatisfaction over human resources issues and structural changes by the management internally. The findings revealed that some workers took incapacity leave for long periods, sometimes more than three years at a time. The emergency workers are at high risk of being infected by ordinary TB or the more complex type, the DR-TB in their line of duty. The study revealed that there were no health and safety structures in the institution; as a result there was no formal documenting and identification of hazards in order to implement measures to protect the workers from future incidences. Health related absenteeism was high when employees were exposed to such hazards and replacement of skill was not implemented. The main recommendations included wearing of personal protective equipment, safe disposal of sharps objects, guidelines for lifting objects, introduction of organizational safety culture and safe transportation of PTB patients.

Brand awareness of students at the Nelson Mandela Metropolitan University

Huang, Wei January 2005 (has links)
To ensure a long-term successful product brand, it is important to build brand awareness, to reach the consumer’s mind, encourage a consumer to develop a preference and eventually provide a positive contribution to consumer decision-making. Therefore, there is a need to understand and identify the role of brand awareness in the purchase process. An understanding of students as consumers and their brand awareness is important to marketers, particularly as students are recognised as a specialised market segment for a variety of products. The research focused on identifying the differences, if any, in brand awareness and its role in students’ purchase of sportswear clothing and sportswear shoes (high-involvement products) and coffee (a low-involvement product). A drop-off survey was used to collect the required empirical data from a convenience sample of 450 students enrolled at the Nelson Mandela Metropolitan University. The empirical findings showed that students were more aware of sportswear clothing and shoe brands than of coffee brands. Advertising played an important role in the awareness of sportswear shoes and clothing brands, but seemed unimportant in the case of coffee. Brand elements were found to enhance brand awareness. The brand name was important for coffee, while the name and the logo played a role in students’ awareness of sportswear brands. The study deduced that differences in brand awareness between high-involvement and low-involvement products exist among the students. Marketers thus need to choose appropriate strategies to create and increase brand awareness for the different products.

Analysis of ICT governance initiatives as a mechanism to enhance corporate governance, with particular reference to Nelson Mandela Bay Municipality

Tolom, Sindiswa January 2013 (has links)
Developing countries such as South Africa have a tremendous potential for rapid and sustainable economic and social development by leveraging the benefits and advantages of Information and Communication Technology (ICT) and applying it appropriately within the local government sector. As such, the Local Government Turnaround Strategy’s (LGTAS) vision states that: Each municipality must have the necessary ICT infrastructure and connectivity; and that ICT systems must be put in place across all municipalities to accelerate service delivery, and improve efficiency and accountability. However, technology on its own cannot achieve much; it must be supported by capable people and tested processes to provide services in which the public can have confidence. Disparities, both from within the municipal sector as well as in the larger South African ICT landscape, have influenced the manner in which municipalities make use of ICT. Nevertheless, it has been observed that despite the use of ICT, there has been a lack of utilising ICT governance to enhance corporate governance in the public sector, particularly in municipalities. In this study, an analysis was made of ICT governance initiatives, as a mechanism to enhance corporate governance, with particular reference to the Nelson Mandela Bay Municipality (NMBM) in the Eastern Cape. The research itself has identified risk levels that exist as a result of the lack of ICT governance and risk management. The respondents were given an opportunity to agree or disagree with statements regarding the state of ICT provision and support, corporate governance and other elements within the institution. The researcher has formulated recommendations to solve identified problem based in the research results in ICT governance and corporate governance. While governance developments have primarily been driven by the need for transparency regarding enterprise risks and the protection of shareholder value, the pervasive use of technology has created a critical dependency on ICT that calls for a specific focus on ICT governance. ICT governance is part of corporate governance,which is the responsibility of the organisation’s top executive, to ensure that its information technology supports the goals and objectives of the organisation, through a variety of structural mechanisms, processes and mechanisms for communication. Fundamentally, ICT governance is concerned with whether ICT is delivering value and the management of ICT risks, driven by a strategic alignment between business and ICT, resources management and performance management. The corporate governance of ICT involves evaluating and directing the plans for the use of ICT to support the Institution and monitoring these. It includes the strategy and policies for using ICT within the institution. The executive authority and executive management are accountable and responsible for ensuring that the governance of ICT is implemented in the institution in line with this framework.

The psychofortology of post-graduate learners in the Faculty of Health Sciences at the Nelson Mandela Metropolitan University

Smith, Greg January 2007 (has links)
The years spent studying towards a degree represent many challenges to the learner1. These pressures increase once that learner moves into the post-graduate level of professional study. Faced with the pressure of having to perform suitably in order to remain on the programme, the learner finds himself or herself under conditions which may present as stress or illness, depending upon the availability of coping resources and strategies. This study adopted a psychofortigenic2 approach and explored and described the coping (i.e., coping resources and sense of coherence) and subjective well-being (i.e., satisfaction with life, happiness and general psychiatric health) of post-graduate learners in the following six departments of the Faculty of Health Sciences at the Nelson Mandela Metropolitan University (NMMU): Psychology; Human Movement Science and Sport Management; Environmental Health and Social Development Professions (incorporating MA Health and Welfare Management); Pharmacy; Nursing Science; Biomedical Technology and Radiography. An exploratory descriptive research design was used and the participants were selected by means of non-probability, convenience sampling. The sample consisted of 60 male and female masters and doctoral post-graduate learners in the Faculty of Health Sciences. Biographical data was gathered by means of the administration of a questionnaire. Hammer and Marting’s (1988) Coping Resources Inventory was used to measure the students’ available coping resources. Furthermore, Antonovsky’s (1987) Orientation to Life Scale was used to measure the construct of Sense of Coherence. The Satisfaction with Life Scale by Diener, Emmons, Larson and Griffin (1985) was used to assess the respondents’ overall satisfaction with life. Kamman and Flett’s (1983) Affectometer-2 was used to measure participants’ subjective global happiness. The General Health Questionnaire of Goldberg and Williams (1988) was used to measure the psychiatric morbidity or general psychiatric health of the participants. The data was analyzed using both descriptive statistics and cluster analysis. A Hotellings T² was computed with subsequent t-tests to draw inferences about differences in the means of established groups across the five measures. The results indicated that the participants were generally coping and experiencing subjective well-being. The results indicated two clusters to significantly differ from one another across the five measures. The first cluster could be characterized as high in psychofortology and presented with better coping and subjective well-being. The second cluster could be characterized as low in psychofortology and presented with poorer coping and subjective well-being.

Subtle racism amongst undergraduate learners after a decade of democracy

Van der Westhuizen, Amanda January 2007 (has links)
The concept of “race” has been the organising feature of South African society for more than three centuries. More recent social changes in the United States of America, Europe, Australia, and South Africa have lead to more subtle expressions of racism. The present study aimed to explore and describe subtle racism amongst undergraduate psychology learners at a tertiary institution in Nelson Mandela Metropolitan Municipality in 2004. The Subtle Racism Scale was used to measure anti-Black sentiment among a sample of 286 undergraduate psychology learners, obtained through non–probability, convenience sampling. Multiple regression analysis revealed the independent variables of race, age, and the race-age interaction were significantly associated with subtle racism of the participants. Research results demonstrated that participants’ level of estimated subtle racism varied according to the age and race of the participants, supporting the notion that racism in South Africa did not influence different age and race groups in a uniform manner.

NMMU alumni as non-donors : why NMMU alumni do not become donors to the institution

Knoesen, Evert Philip January 2010 (has links)
This project investigates why alumni do not become donors to the Nelson Mandela Metropolitan University. Interviews with non-donors created the opportunity for an in depth qualitative examination of the motivating process that led these non-donors to abstain from giving. This study used the Van Slyke and Brooks (Van Slyke & Brooks, 2005) model of alumni giving and the Schervish (Schervish, The spiritual horizon of philianthropy: New directors for money and motives, 2000) supply side theory of philanthropy, which has been successfully applied in similar studies (Wastyn, 2008), to provide the conceptual framework. This framework maintains that donors and non-donors differ in that the manner in which they socially construct their university experience in creating their own realities. This constructed reality becomes the filter through which non-donors pass requests for financial support (whether direct or indirect) from the institution. The study revealed that at NMMU factors including generic donor behaviour among alumni, the status of current non-donors as being mostly past donors to their respective constituent institution, attitudes toward the institutional reputation (or aspects thereof) of the NMMU, identified obstacles to engagement, pervasive negative attitudes to institutional giving and alumni support for commercialised but not tiered giving activities, can play a major role in restructuring the manner in which non-donor alumni should be approached. The study demonstrates the need to include non-donors in research that explores alumni giving to the university. It confirms the distinct impact of the abnormally distributed demographic characteristics of this university and confirms that examining the impact of these characteristics and experiences cannot be effectively done by simply relying on one or two simple variables. Being a management project, 13 (thirteen) distinct categories of management recommendations are made, ranging from strategy development, through accounting and budgeting practice, to proposing specific revenue generating initiatives. The study concludes with the view that Alumni can and should be able to make a notable contribution to the revenue of the university and in so doing, contribute to the sustainability of the pro-social transformation process of the Nelson Mandela Metropolitan University.

The socio-economic impacts of xenophobia in South Africa: a case study of the Nelson Mandela Bay Metropole

Yawlui, Robert Mensah January 2013 (has links)
Xenophobia became known as manifest of relations and perceptions of an "in–group" towards an "out-group", including a fear of losing identity, suspicion of its activities, aggressions, and desire to eliminate its presence to secure a presumed purity. This study aims to address the socio-economic impacts of xenophobia in South Africa. As a matter of fact, the 2008 xenophobia attacks amongst others were violent and acted as visible wake-up call to the country to focus attention on the reality of human migration. South African democratic constitution recognises immigration, and gives multiple reasons why nationals from other countries have to migrate to settle in South Africa. This study was grounded within the field of Development studies and undertook a case study of investigating the socio- economic impacts of xenophobia in Nelson Mandela Bay Metropole (NMBM) as a case study. The study employed the use of semi- structured interviews whereby a questionnaire was used to guide the researcher in the interview process. A total of 40 officials were interviewed, ranging from governmental department through to civil societies to private immigration consultants and immigrants in South Africa, in order to avoid the generation of biases. The data obtained from respondents were presented, analysed, and discussed. From the data collected, it was possible to single out the impacts of xenophobia in NMBM. Some of the consequences generated from the fact that the community need more awareness programs, the local and national government need to capacitate the citizens to create sustainable jobs and the DoHA‟s activities greatly relegate immigrants to the backyard. Based on the study findings, the main recommendations offered to NMBM was to create a forum to advice the DoHA to channel efforts into managing migration issues sustainably rather than "stopping" it. Furthermore to catalyse Civil Society and NGOs to initiate support mechanisms to hold government accountable. This will greatly provide a perfect platform for development.

Evaluating the extent to which Nelson Mandela Metropolitan University (NMMU) libraries meet student expectations

Zhibing, Mu January 2006 (has links)
The failure to evaluate the service quality by comparing service expectations and service perceptions of students requires that the management of NMMU libraries identify the service expectations and service perceptions of students and measure the gaps between these service expectations and service perceptions of students. A literature review was conducted to explore the service expectations and service perceptions of students. An effective method (using the LibQUAL model) to evaluate the service quality of NMMU libraries based on the service expectations of students was described. Thereafter, a LibQUAL survey was used to collect the required empirical data from a convenience sample of 2 047 students enrolled at NMMU. The empirical findings showed that gaps existed between the service expectations and service perceptions of students at different campuses of NMMU. At different campuses of NMMU, the service expectations of students were not met in term of the service perceptions of the four dimensions (affect of service, library as place, information access and personal control) of the LibQUAL model. ii The study identified the gaps between the service expectations and service perceptions of students at different NMMU campuses and conclusions and recommendations based on these gaps were formulated. The management of the NMMU libraries needs to choose appropriate strategies to improve the quality of NMMU library services based on the service expectations of students.

Enterpreneurial orientation at Nelson Mandela Metropolitan University

Fadairo, Feyisara Olufunmilayo January 2014 (has links)
In the knowledge world into which mankind has progressed, universities are engines of economic growth. Their role has changed from producers of labour force to equal contributors - along with government and industry- in regional and national economic and social growth and development. Universities that will survive and succeed in this new climate must embrace entrepreneurship - become entrepreneurially oriented. As in any other organisation corporate entrepreneurship processes explain how entrepreneurship is implemented and diffused throughout a university, and its members must perceive the internal organisational culture as innovation supporting for entrepreneurship to flourish. Hence, the importance of studying internal environmental conditions that influence / enable corporate entrepreneurship. This study investigated NMMU’s entrepreneurial orientation by first determining what an entrepreneurial university is and its key attributes. Next it identified the key structural factors influencing university entrepreneurship and enquired how these structural factors can be influenced to enhance entrepreneurship at NMMU. To this end, survey method was used to sample perception of the university middle managers. The study first determined the level of entrepreneurship in NMMU by measuring its entrepreneurial intensity and then attempted to locate its position on the entrepreneurial grid. Next the level of the university’s internal environmental support for entrepreneurship was determined. The university’s culture was found to be the key factor influencing entrepreneurship with time availability and work discretion as key internal factors through which NMMU’s entrepreneurial culture could be improved. Proactivity and frequency dimensions of entrepreneurship were found to lead to significant improvement in the university’s entrepreneurial output and based on the outcome of the study; suggestions were made on ways of incorporating findings to better improve entrepreneurial orientation.
