Assessment of energy efficiency in selected guest houses in Mpumalanga ProvinceMachete, Fannie 01 1900 (has links)
The increase in the number of guest houses is applausive for its socio-economic benefits through income generation, job creation and entrepreneurship growth. However, the increase in the number of guest houses is proportional to energy demand. Thus, increase in energy efficient guest houses is more desirable in order to achieve sustainable development. Therefore, the aim of this study was to assess energy efficiency in selected guest houses in Mpumalanga province
Through in-depth literature analysis, an energy efficiency framework that builds on and advances the input-output ration and energy saving model was developed. This framework has five indicators which are categorised into financial and nonfinancial, namely: energy quantity, cost, carbon equivalence, services quantity and quality. The framework clarified the differences between energy saving and energy efficiency, while it identifies energy saving and services levels as two parameters or components of energy efficiency. This framework was later implemented and used to assess energy efficiency in eight selected guest houses in Mpumalanga province. To assess energy efficiency using the framework, three standard or common services in guest houses such as indoor lighting, water heating and indoor thermal comfort were
assessed for energy saving and compliance with industry standards.
The results of the assessment were analysed through descriptive statistical and explanatory methods. Using the framework, the study found that few of the selected guest houses did save energy in one or more of the standards services. However, some methods used in the guest houses were found to be highly costly and resulted in high energy quantity consumption and high carbon footprint.
Thus, these methods failed the test for characterisation of energy saving methods. Furthermore, the study found that all indoor lighting services didn’t meet minimum industry standards for indoor lighting of 100lux. All water heating standards were compliant, while indoor thermal comfort standards differed among guest houses. Thus, none of the guest houses met the minimum criteria for characterisation as being energy-efficient. However, different services qualified.
Hence, the findings confirm that the energy efficiency framework was effective and reliable in the characterisation of energy-efficient guest houses. This framework builds on and advances the input-output ratio and energy saving models previously used. / Environmental Sciences / PhD (Environmental Management)

Exploring the development of an integrated, participative, water quality management process for the Crocodile River catchment, focusing on the sugar industrySahula, Asiphe January 2015 (has links)
Water quality deterioration is reaching crisis proportions in South Africa. Many South African catchments are over-allocated, and decreasing volumes of source water mean increasing concentrations of pollutants. The Crocodile River Catchment in the Mpumalanga province in South Africa was identified through previous research, as a catchment faced with deteriorating source water quality for water users in the catchment. Poor source water quality has become a sufficiently acute concern for the stakeholders in this catchment to co-operate in developing a process that assists with compliance control of their water use and waste disposal to reduce costs, decrease industrial risks as water quality compliance increases, and improve source water quality. The sugar industry is downstream within the Crocodile River Catchment, and is affected by the activities of all upstream water users; the industry is thus dependent on the stakeholders upstream participating in the effective management of the resource. However, the sugar industry is also located just before the confluence of the Crocodile River and Komati River upstream of the Mozambique border, and thus the water quality of the sugar industry effluent will affect the quality of the water that flows into Mozambique. The sugar industry is on the opposite river bank to the Kruger National Park, which has high water resource protection goals. Therefore, the sugar industry has a national role to play in the management of water resources in the Crocodile River Catchment. This study provides a focused view of the role of the sugar industry in the development of a co-operative, integrated water quality management process (IWQMP) in the Crocodile River Catchment. In order to address the objectives of this study, this research drew from an understanding of the social processes that influence water management practices within the sugar industry as well as social processes that influence the role of the Inkomati-Usuthu Catchment Management Agency as the main governing institution in water resource management in the Inkomati Water Management Area. The study also drew from an understanding of scientific knowledge in terms of a water chemistry which describes the upstream and downstream water quality impacts related to the sugar industry. The water quality analysis for the Lower Crocodile River Catchment shows a decline in water quality in terms of Total Dissolved Solids (TDS) loads when moving from below Mbombela to the Mozambique border. The major sources of TDS in the Lower Crocodile River are point source dominated, which may be attributed to the extensive mining, industrial and municipal activities that occur across the catchment. When observing Total Alkalinity (TAL) and pH values from below Mbombela to the furthest monitoring point, there is deterioration in the quality of the water in the Lower Crocodile River, with the Kaap River contributing a negative effect that is diluted by the Crocodile main stem. The Hectorspruit Waste Water Treatment Works (WWTWs) (located in the Lower Crocodile River Catchment) contributes high concentrations of TDS and TAL into the Crocodile River. Total Inorganic Nitrogen and Soluble Reactive Phosphorus concentrations decrease in the lower reaches of the Crocodile River compared with the river below Mbombela, which can be attributed to the extensive sugar cane plantations located in the Lower Crocodile River Catchment acting as an “agricultural wetland” that serves a function of bioremediation resulting in large scale absorption of nutrients. This is an interesting result as earlier assumptions were that fertiliser application would result in an overall increase in nutrient loads and concentrations. Biomonitoring data show no substantial change in aquatic health in the LowerCrocodile River Catchment. For a catchment that has an extensive agricultural land use in terms of sugarcane and citrus production, the Crocodile River is unexpectedly not in a toxic state in terms of aquatic health. This is a positive result and it suggests that pesticide use is strictly controlled in the sugar and citrus industry in the Crocodile River Catchment. For long term sustainability, it is essential for the sugar industry to maintain (and possibly improve) this pesticide management. The social component of this study aimed to provide an analysis of the management practices of the sugar mill as well as examining agricultural practices in the sugar cane fields in relation to water quality management through the use of Cultural Historical Activity System Theory (CHAT). This component showed that there are contradictions within the sugar industry activity system that are considered to be areas of “tension” that can be loosened or focused on to improve the contribution the sugar industry can make to the IWQMP. Surfacing contradictions within the sugar industry activity system and the Inkomati-Usuthu Catchment Management Agency activity systems highlighted areas of potential for learning and change. While an understanding of biophysical processes through scientific knowledge is critical in water management decision making, it is evident that an understanding of other actors, institutions and networks that inform water quality management decision-making also plays a significant role. The notion of improving the role of scientific or biophysical knowledge in contributing to socio-ecologically robust knowledge co-creation, decisions and actions towards resolving water quality problems is emphasised. Specifically, moving towards improving interactions between scientists and other actors (water users in the Crocodile Catchment in this case), so that scientific practices become more orientated towards societal platforms where water quality management is tackled to enable improved water quality management practices. Therefore, linking the social and biophysical components in this study provides a holistic understanding of how the sugar industry can contribute to the development of an IWQMP for the Crocodile River catchment.

An explorative study of rural women's peceptions [sic] of sexuality and HIV prevention in their local socio-cultural context : a case study of rural Schoemansdal, MpumalangaChauke, Tinyiko 02 1900 (has links)
Socio-cultural factors oppress and construct women as men’s objects of desire and pleasure, thus increasing women’s vulnerability to HIV infection and, subsequently, maintaining the HIV and AIDS epidemic and prevalence in South Africa’s rural areas. South Africa’s rural women and their sexuality has not received adequate attention to date. This qualitative study sought to explore rural women’s perceptions on their sexuality and HIV prevention within the socio-cultural context of Schoemansdal (South Africa). A sample of ten participants, who are women from the Swazi ethnic group between the ages of twenty and fifty, were purposefully drawn to participate in this study. Data were collected by means of tape–recorded, face-to-face interviews and focus group discussions. Results of the study reveal that women’s social and cultural contexts have an influence on their perceptions of sexuality and HIV prevention, and that this poses a hindrance to women’s HIV-prevention behaviours such as condom use. The study’s findings reveal that in examining HIV infection and prevention, women’s diverse contexts and experiences cannot continue to be overlooked. This is because they may provide relevant understanding of the epidemic that is plaguing South Africa’s rural women. / An explorative study of rural women's perceptions of sexuality and HIV prevention in their local socio-cultural context : a case study of rural Schoemansdal, Mpumalanga / Social Work / M.A. (Social Behaviour Studies in HIV/AIDS)

Teachers’ perspectives on continuing professional development : a case study of the Mpumalanga Secondary Science Initiative (MSSI) projectMokhele, Matseliso Lineo 08 1900 (has links)
Continuing Professional Development (CPD) of teachers is increasingly becoming a priority in most countries throughout the world. It is widely viewed as the most effective approach to prepare teachers adequately, and to improve their instructional and intervention practices, for when they enter the workforce (Fraser et al 2007). Despite the general acceptance of CPD programmes as essential to the improvement of education, reviews of professional development research constantly point out the ineffectiveness of most of these programmes (see Cohen and Hill, 1998 and 2000). Furthermore, many teachers express dissatisfaction with the professional development opportunities made available to them in schools and insist that the most effective development programmes they have experienced have been self-initiated (National Research Council, 2007). There is a consensus that many CPD programmes have yet to understand professional development from a teacher‘s perspective. This perspective acknowledges what drives teachers to enlist in these programmes and how such programmes can make a difference to them and their classrooms.
Therefore, this study seeks to return the emphasis of professional development to the teachers. The study explores the teachers‘ perspectives of CPD in general, the personal meaning of CPD, and its meaning in the context of their work. By interviewing the teachers who were part of the Mpumalanga Secondary Science Initiative (MSSI) project (a seven year science and mathematics professional development intervention), I explore: the teachers‘ opinions of the intervention; its meaning to them and their work; and its impact on their classroom practices and students for the duration of the intervention and beyond. In this study, I explore data from an extensive and longitudinal study of teachers who were part of the CPD programme in greater detail. In discussing my data, I propose that CPD, however well intentioned and executed, is received differently by each teacher as a result of their personal circumstances and investment in the programme. I argue that the greater the unity between the personal circumstances and motivations of the teachers and those of the CPD intervention, the more likely the outcome will be meaningful for the participating teachers. In turn, the ability to sustain the benefits of the intervention will be enhanced. / Further Teacher Education / D.Ed. (Curriculum Studies)

Facilitating the self-efficacy of primary school teachers in Mpumalanga : a perspective from lifelong learningLa Cock, Yolande 02 1900 (has links)
The aim of this research was to make recommendations on how to facilitate a healthy sense of Computer Self-Efficacy (CSE) in teachers of a primary school in South Africa. A literature study was conducted to determine a theoretical framework for the study. Thereafter a mixed method design was used to conduct an empirical investigation. This was done by means of focus group interviews, questionnaires and an observational narrative. The most important finding was that the teachers who participated in the research were professional and enlightened about the value of technology. They agreed that although daunted by the idea of technology it is essential for them to become proficient in the use of computers. The researcher came to the conclusion that the main obstacle that stands between the participants and technological proficiency was a weak sense of CSE. Recommendations were made on how one could use extrinsic motivation to introduce new technology in such a way as to enhance self-efficacy and as result computer self-efficacy. / Curriculum and Instructional Studies / M.

Teacher mentorship as professional development : experiences of Mpumalanga primary school natural science teachers as menteesVan der Nest, Adriana 11 1900 (has links)
Mentorship as a tool to develop the pedagogical and content knowledge of inservice
teachers, regardless of experience, is a field in education which has gained
popularity worldwide. The review of literature however, provided evidence that
mentoring in education has primarily focused on the benefits received by novice
teachers and not experienced teachers. Areas addressed in the literature review
include the important role of continuous professional development programmes in
the improvement of the teachers’ classroom practices and by inference, their
learners’ achievements.
The purpose of this study was to explore and describe the experiences and
understandings of seven experienced natural science teachers as mentees in a
professional development programme (the ILLS project). Through the use of a
qualitative case study approach, I examined the activities that supported the
development of the participants as they interacted with the guided support of a
mentor teacher, and aimed to understand how the mentees made sense of their
experiences in this mentoring relationship. The activities included lesson-planning,
classroom observations and reflection meetings and the professional development
support, through mentoring, was embedded on-site and in-context.
This research revealed that the mentee teachers were motivated by the opportunity
to enhance their professional growth through the support of a mentor. The teachers
also perceived that their subject content and pedagogical knowledge were enriched
by participating in the mentoring process. / Science and Technology Education / M. Ed. (Natural Science Education)

From communication to communigation: a conceptual model to strengthen South Africa’s government communication system – the case of Mpumalanga ProvinceRamodibe, Mohau Armatto 10 1900 (has links)
Text in English / This study adopted a quantitative approach in order to produce numbers in
relation to the diffusion of the new media. A descriptive quantitative survey was
conducted – with sampling done in multi-stage probability – which comprised
clustering, simple random, systematic, stratified sampling techniques,
convenience and census sampling. A sample size of 379 respondents was
selected, comprising 347 citizen-respondents and 32 government
communicators (heads of communication). Data was collected utilising two (2)
standardised questionnaires – one tailor-made for the citizens and the other for
government communicators. Informed by the Diffusion of Innovations theory, this
study has established that new media channels have difussed extensively within
communities in the Province of Mpumalanga. This has provided a strong
motivation to recommend that the communication policy of the South African
government be amended, to include new media channels, like social media, as
official government communication channels. / Communication Science / D. Litt. et Phil. (Communication)

Social capital and cooperative enterprise development : a case study in Mpumalanga, South AfricaManthata, Grace Tshegofatso 01 1900 (has links)
Social capital is a concept that is broadly referred to as norms, networks, trust and forms of social connections that allow people to act collectively. This study explores the role of social capital in the process of developing micro-enterprises cooperatively. The study attempts to delve beneath how social capital manifests in different social contexts found in developing communities such as Masana. The field-work observations and the data collected through a qualitative research design provided abundant evidence of social capital, and the profile that emerged reaffirmed the argument that the outcomes of social capital can be both negative and positive. This study argues that to better leverage social capital for development initiatives, development planners and implementers need to understand social capital as potentially both a blessing and blight. Hopefully this sudy will contribute to the body of knowledge and influence development policies and interventions that leverage social capital for development initiatives. / Sociology / M.A. (Sociology)
