- Description: This work presents a study of high-spin states in the nucleus ¹⁹⁶Tl via γ-spectroscopy. ¹⁹⁶Tl was produced via the ¹⁹⁷Au(⁴He,5n) ¹⁹⁶Tl reaction at a beam energy of 63 MeV. The γ-γ coincidence measurements were performed using the AFRODITE γ-spectrometer array at iThemba LABS. The previous level scheme of ¹⁹⁶Tl has been extended up to an excitation of 4071 keV including 24 new γ-ray transitions. The spin and parity assignment to levels was made from the directional correlation of oriented nuclei (DCO) and linear polarization anisotropy ratios. An analysis of the B(M1)/B(E2) ratios was found to be consistent with the configuration of πh₉/₂♁vi₁₃/₂ for the ground state band. Although no chiral band was found in ¹⁹⁶TI and ¹⁹⁸TI.

- Description: Music’s significant contribution to the holistic development of the young learner is uncontested and confirmed by views of seminal scholars, such as Nzewi 2003, Reimer 2003, Nussbaum 2001, Elliot 1994 and Merriam 1964, amongst others. As such, music education supports basic values of self-growth, self-knowledge and enjoyment. This study argues for the vital importance of music education in Grade R in the South African schooling system where teachers can successfully implement the curriculum. In post-apartheid multicultural and multi-musical South Africa music education in Grade R is the sole responsibility of the generalist Grade R teacher. However, due to inadequate training and minimal, unproductive in-service initiatives, the vast majority of Reception Year teachers assumingly do not have the required competences to teach music in a way that maximally enhances the holistic development of their learners. Findings revealed that teachers exhibited limited, if any, musical knowledge and per se, they are insufficiently skilled in the effective delivery of the curriculum in terms of music. This study acknowledges the need to equip in-service Grade R teachers with the required competences to effectively implement the national school and teach music with confidence. The lack of successful and effective continuing professional teacher development initiatives from the Department of Education and Department of Basic Education to assist Grade R teachers in teaching music, was a serious concern to me. This concern reinforced the motivation to embark on this project. In this thesis, I report on an intervention strategy aimed at enabling three Grade R practitioners at one peri- urban township school in the Eastern Cape to improve their music education competencies. These three Coloured ladies only held a Certificate in Early Childhood Development, rating at an NQF level 4 and 5. None of these practitioners had any prior music experience in music training, music making or music teaching. I utilised a Participatory Action Learning and Action Research (PALAR). PALAR combines research with development and is thus highly suitable when addressing multifaceted problems in rapidly changing environments, such as South Africa. In my study, the participants were thus actively involved in identifying problems and creating solutions. A number of collaborative interactions and qualitative data generation strategies such as Focus Group Interviews, Observations, Drawing, Interviews, Narrative Inquiry, Case Study and Reflective Journals were implemented. Findings indicated that the practitioners experienced transformation on both a professional and personal level as they discovered and tapped into their own innate musical competences. This enabled them to explore ways to teach music that enhanced the holistic development of their learners, developing them physically, cognitively emotionally, socially, and musically. Learners likewise benefitted from the intervention as they experienced social cohesion in a multicultural classroom and gained the fruits of music’s remedial impact and therapeutic value in their lives.

- Description: The discussion on the extent to which audit committees perform the oversight function of financial governance is important. This is particularly so in the Eastern Cape where the implementation of the Public Finance Management Act (PFMA) of 1999 has not significantly improved financial management. The deteriorating financial management environment of provincial departments impacts negatively on service delivery and is therefore a matter of great concern to the political administrators at both national and provincial levels. The objective of this study is to determine how effective audit committees are in Eastern Cape provincial departments and how this translates into good financial governance and, ultimately, improved service delivery. To achieve this objective, a literature review of the link between audit committee effectiveness, accountability and corporate governance in the public sector was conducted. It was found that audit committees in the public sector have similar responsibilities to that of the private sector and lack of accountability in the public sector impacts negatively on service delivery. A second literature review was conducted to highlight the current state of public financial management in South Africa and how this has had an impact on financial management in Eastern Cape provincial departments. A qualitative research methodology was applied because the researcher is of the opinion that the research question asked is more interpretive than predictive. An interview survey was conducted in which senior management officials were selected from provincial departments and interviewed using semi-structured questions. The research study concluded, that provincial departments in the Eastern Cape have all established audit committees in line with the Public Finance Management Act (PFMA) National Treasury regulations. These committees are however ineffective. Ineffectiveness is as a result of, among other factors, lack of stability in accounting officer and chief financial officer positions. Secondly, senior management have not been made to account for the persistent negative audit outcomes in their departments. The research recommends that the political leadership of the province should ensure stability in leadership, particularly in the position of accounting officer and the chief financial officer.

- Description: Governments all over the world are faced with numerous challenges while running their countries on a daily basis. The predominant challenges which arise are those which involve statistical methodologies. Official statistics to South Africa’s infrastructure are very important and because of this it is important that an effort is made to reduce the challenges that occur during the development of official statistics. For official statistics to be developed successfully quality standards need to be built into an organisational framework and form a system of architecture (Statistics New Zealand 2009:1). Therefore, this study seeks to develop a statistical methodology that is appropriate and scientifically correct using an automated statistical system for audits in government regulatory authorities. The study makes use of Mathematica to provide guidelines on how to develop and use an automated statistical audit system. A comprehensive literature study was conducted using existing secondary sources. A quantitative research paradigm was adopted for this study, to empirically assess the demographic characteristics of tenants of Social Housing Estates and their perceptions towards the rental units they inhabit. More specifically a descriptive study was undertaken. Furthermore, a sample size was selected by means of convenience sampling for a case study on SHRA to assess the respondent’s biographical information. From this sample, a pilot study was conducted investigating the general perceptions of the respondents regarding the physical conditions and quality of their units. The technical development of an automated statistical audit system was discussed. This process involved the development and use of a questionnaire design tool, statistical analysis and reporting and how Mathematica software served as a platform for developing the system. The findings of this study provide insights on how government regulatory authorities can best utilise automated statistical audits for regulation purposes and achieved this by developing an automated statistical audit system for government regulatory authorities. It is hoped that the findings of this study will provide government regulatory authorities with practical suggestions or solutions regarding the generating of official statistics for regulatory purposes, and that the suggestions for future research will inspire future researchers to further investigate automated statistical audit systems, statistical analysis, automated questionnaire development, and government regulatory authorities individually.

I argue that the construction and evolution of Saharawi music in the camps is divided into two main areas: nationalism in relation to the decolonisation of Western Sahara, and maintenance of cultural values in Saharawi music found in the historical retention of the Haul modal system originating in precolonial Saharawi culture. Local audiences use the term Azawan to define the combination of nationalist sentiments and retention of their precolonial musical culture in Saharawi music.

- Description: The generation of environmental pollutants worldwide is mainly due to over reliance on fossil fuels as a source of energy. As a result of the negative impacts of these pollutants on the health of humans, animals, plants and microorganisms, global attention has been directed towards ways of containing this problem. Biodegradation of fossil fuel is one of the most effective methods used to remediate contaminated systems. However with regard to coal waste, much of what is known is based on the ability of fungal species to biosolubilize this material under enrichment conditions in a laboratory setting. For effective biodegradation as a remediation technique, there is an immediate need to source, isolate, enrich and incorporate other microorganisms such as bacteria into bioremediation technologies. The goal of this dissertation was to isolate bacteria from fossil fuel contaminated environments and to demonstrate competence for petroleum hydrocarbon degradation which was achieved using a combination of analytical methods such as spectrophotometry, FT-IR, SEM and GC-MS. Screening for biodegradation of coal and petroleum hydrocarbon waste resulted in the isolation of 75 bacterial strains of which 15 showed good potential for use in developing remedial biotechnologies. Spectrophotometric analysis of bacteria both in coal and petroleum hydrocarbons (all in aqueous media) revealed a high proliferation of bacteria in these media suggesting that these microbes can effectively utilize the various substrates as a source of carbon. The isolated bacteria effectively degraded and converted waste coal to humic and fulvic acids; products required to enrich coal mine dumps to support re-vegetation. Scanning electron microscopy showed the attachment of bacteria to waste coal surfaces and the disintegration of coal structures while FT-IR analysis of extracted humic-like substances from biodegraded waste coal revealed these to have the same functional groups as commercial humic acid. Specific consortia which were established using the isolated bacterial strains, showed greater potential to biodegrade coal than did individual isolates. This was evident in experiments carried out on coal and hydrocarbons where the efficient colonization and utilization of these substrates by each bacterial consortium was observed due to the effect of added nutrients such as algae. The biodegradation of liquid petroleum hydrocarbons (diesel and BTEX) was also achieved using the 15 bacterial isolates. GC-MS analysis of extracted residual PHC from aqueous and solid media revealed rapid breakdown of these contaminants by bacteria. Different bacterial consortia established from the individual isolates were shown to be more efficient than single isolates indicating that formulated consortia are the biocatalysts of choice for fossil fuel biodegradation. This study represents one of the most detailed screenings for bacteria from fossil fuel contaminated sites and the isolation of strains with potential to biodegrade coal and petroleum hydrocarbon wastes. Several consortia have been developed and these show potential for further development as biocatalysts for use in bioremediation technology development. An evaluation of efficiency of each established bacterial consortium for biodegradation in a commercial and/or industrial setting at pilot scale is now needed.

- Description: There is growing concern among governments, scientists, agricultural practitioners and the general public regarding the negative implications of widespread synthetic chemical pesticide application for the control of crop pests. As a result, baculovirus biopesticides are gaining popularity as components of integrated pest management (IPM) programmes in many countries despite several disadvantages related to slow speed of kill, limited host range and complex large scale production. In South Africa, baculoviruses are incorporated into IPM programmes for the control of crop pests in the field, and recent bioprospecting has led to the characterisation of several novel isolates with the potential to be formulated as commercial products. This contribution will provide an overview of the use of baculoviruses against insect pests in South Africa, as well as research and development efforts aimed at broadening their application as biocontrol agents. Challenges faced by researchers in developmental projects as well as potential users of baculoviruses as biopesticides in the field are also discussed.

- Description: The focus of this study is on understanding the multiple and interacting factors that hinder or enable municipal planned climate change adaptation, here called barriers and enablers respectively, and their implications for community based adaptation. To do this I developed a conceptual framework of barriers to and enablers of planned climate change adaptation, which informed a systematic literature review of barriers to planned community based adaptation in developing countries. In this framework barriers were grouped into resource, social and physical barriers. I then conducted empirical case study analysis using qualitative research methods in four South African municipalities to understand what barriers and enablers manifested in these contexts. In light of the reflexive nature of my methodology, my framework was adjusted based on my empirical findings, where contextual barriers were found to better represent the empirical results and subsumed physical barriers. I found my framework useful for analysis, but in the empirical cases, barriers and enablers overlaid and interacted so significantly that in reality it was often difficult to separate them. A key finding was that enablers tended to be more about the way things are done, as opposed to direct opposites of barriers. Comparison of barriers and enablers across the case studies revealed a number of key themes. Municipalities struggle to implement climate change adaptation and community based adaptation within contexts of significant social, economic and ecological challenges. These contextual barriers, when combined with certain cognitive barriers, lead to reactive responses. Existing municipal systems and structures make it difficult to enable climate change adaptation, which is inherently cross‐sectoral and messy, and especially community based adaptation that is bottom‐up and participatory. Lack of locally applicable knowledge, funding and human resources were found to be significant resource barriers, and were often underlain by social barriers relating to perceptions, norms, discourses and governance challenges. Enablers of engaged officials, operating within enabling organisational environments and drawing on partnerships and networks, were able to overcome or circumvent these barriers. When these enablers coincided with windows of opportunity that increased the prioritisation of climate change within the municipality, projects with ancillary benefits were often implemented. Analysis of the barriers and enablers identified in the literature and case studies, informed discussion on whether municipalities are able to implement community based adaptation as defined in the literature, as well as the development of recommendations for how municipal planned climate change adaptation and community based adaptation can be further understood and enabled in the future. These recommendations for practice and research include: (a) To acknowledge and understand the conceptual framings of municipal climate change work, as these framings inform the climate change agenda that is pursued, and hence what municipal climate change adaptation work is done and how it was done. (b) The need for further research into the social barriers that influence the vital enablers of engaged officials, enabling organisational environments, and partnerships and networks. (c) To learn from pilot community‐level interventions that have been implemented by municipalities, as well as from other disciplines and municipalities. (d) To develop top‐down/bottom‐up approaches to enable municipal planned climate change adaptation and community based adaptation, that benefits from high level support and guidance, as well as local level flexibility and learning‐by‐doing. (e) To develop viable mechanisms for municipalities to better engage with the communities they serve.

Lack of locally applicable knowledge, funding and human resources were found to be significant resource barriers, and were often underlain by social barriers relating to perceptions, norms, discourses and governance challenges. Enablers of engaged officials, operating within enabling organisational environments and drawing on partnerships and networks, were able to overcome or circumvent these barriers. When these enablers coincided with windows of opportunity that increased the prioritisation of climate change within the municipality, projects with ancillary benefits were often implemented. Analysis of the barriers and enablers identified in the literature and case studies, informed discussion on whether municipalities are able to implement community based adaptation as defined in the literature, as well as the development of recommendations for how municipal planned climate change adaptation and community based adaptation can be further understood and enabled in the future. These recommendations for practice and research include: (a) To acknowledge and understand the conceptual framings of municipal climate change work, as these framings inform the climate change agenda that is pursued, and hence what municipal climate change adaptation work is done and how it was done. (b) The need for further research into the social barriers that influence the vital enablers of engaged officials, enabling organisational environments, and partnerships and networks. (c) To learn from pilot community‐level interventions that have been implemented by municipalities, as well as from other disciplines and municipalities. (d) To develop top‐down/bottom‐up approaches to enable municipal planned climate change adaptation and community based adaptation, that benefits from high level support and guidance, as well as local level flexibility and learning‐by‐doing. (e) To develop viable mechanisms for municipalities to better engage with the communities they serve.

- Description: This research examined the concept of base erosion and profit shifting in the context of tax schemes employed by multinational corporations. The objective of this thesis was to identify weaknesses within South Africa’s income tax legislation, based on these schemes, and further to propose recommendations to counter the occurrence of base erosion and profit shifting by multinational companies. The research also comprised of a limited review of current global and South African initiatives to address the problem of base erosion and profit shifting. It was concluded that there are a number of weaknesses in the definitions and provisions of the South African income tax legislation that need to be addressed in order to reduce base erosion and profit shifting. Brief recommendations were proposed in relation to each of the weaknesses, in order to address them.

- Description: False codling moth, Thaumatotibia leucotreta Meyrick (1912) (Lepidoptera: Tortricidae), can cause both pre- and post-harvest damage to citrus fruit. Not only can this result in reduced crop yield, but more importantly because of the moth's endemism to sub-Saharan Africa, it is classified as a phytosanitary pest by many export markets. An entire consignment of citrus may be rejected in the presence of a single moth (Moore 2012). Since the bulk of citrus fruit production in South Africa is exported, the control of T. leucotreta is critical (Citrus Growers Association, South Africa 2012). Traditionally, control has been achieved through the use of chemical insecticides; however, residue restrictions, resistance development and concerns about environmental pollution have substantially reduced the dependence on chemical pesticides in citrus. Research on T. leucotreta control has therefore focused on the use of biological organisms (e.g. parasitoids and viruses), which are used as control agents within an integrated pest management (IPM) programme in citrus. These biological control agents, however, only targeted the aboveground life stages of the pest, not the soil-dwelling life stages (late fifth instars, prepupae, pupae), which is the subject of this contribution (Moore 2012).

- Description: Young South Africans are often referred to as the Born Frees - a term which sometimes means people born after 1994, sometimes people born after 1990, or young people who came of age politically after 1994. I've come to really dislike the term Born Frees and particularly the way it is used by the media and the politicians. By calling young people Born Frees, society is using apartheid as a reference point to identify a post-apartheid generation. This reference point (the transition to a 'free' society) unfortunately does not resonate with many of the young people that I've encountered in my research and many feel insulted by the implications of this term, which does not apply to them in any way. Should South African society really be using the transition from apartheid to define its young people and how does it relate to the lives of real young people in South Africa today? Are they really Born Free, free from what, free to do what, free individuals or free as a collective? I will look at some of the stereotypes being used in the mainstream media of Born Frees, and then look at the reaction to this term by some real young South Africans.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: By referring to established concepts and theories which contemplate our experiences in relation to others and space, this thesis examines the interactions and responses of an audience during various participatory artworks. I draw upon Jean-Paul Sartre’s Being and Nothingness and Elizabeth Grosz’ Architecture From The Outside: Essays on Virtual and Real Space in order to understand our interactions with other people, our interactions inside an environment, and the objects and ceremonies we use during these interactions. I align these experiences with the methods which are employed to anticipate and create the interactions between an audience and a participatory artwork. Our daily interactions can be considered a frame that an artist shapes for their represented situation to allow, provide and guide an audience towards their possibilities for movements and actions within a participatory artwork. The interactions that occur in participatory art are done in relation to others and include groups of people interacting with each other rather than an individual disembodied experience. I refer to Claire Bishop in her book, Artificial Hells, and Nicolas Bourriaud in Relational Aesthetics in order to define participatory art. In defining participatory art I focus on the idea that participation is a social activity without which the artwork does not function or exist. I unravel Brett Bailey’s Exhibit A, Anthea Moys Anthea Moys vs The City of Grahamstown and Christian Boltanski’s Personnes in terms of the frame they use to construct participation and interaction. I refer to my own exhibition Ineffaceable as an exploration of these frames which encourage participation. The inside and the outside are a constant theme throughout this thesis and my exhibition. This thematic re-emerges in relation to a number of opposing and fluctuating dynamics: the self and the other; the object and the subject; familiarity and strangeness; the participator and the spectator; the immersive and the disembodied; and the artwork and the audience. Participatory art has not been sufficiently explored particularly in South Africa with South African case studies and particularly from a practical standpoint that includes methodologies for creating participation. This thesis hopes to enrich and contribute to the contemplations on participatory art by focusing on our interactions with others.

- Description: The aim of this study was to investigate the socio-economic perceptions of the beneficiaries of the low income housing scheme in Unit P, of Mdantsane Township, under Buffalo City Metropolitan Municipality. Both quantitative and qualitative approaches were utilised in this study. For instance, questionnaires on the perceptions were administered amongst twenty (20) beneficiaries of this low housing scheme. Semi structured interviews were conducted amongst five (5) respondents who participated in the survey design. The study found that the intervention of providing poor people with houses was not appropriately done as these houses are too small and therefore fail to consider the families of the beneficiaries although the South African government seems to have succeeded to some extent in providing low income housing for the unemployed and those that belong to the low income category. The study also found that the location of Unit P poses a threat because it is located away from all the amenities compelling the beneficiaries to travel more than 5km to the amenities and essential services. The study therefore recommends that the government employs competent contractors that would do a proper job. State officials, tasked with overseeing the various state funded housing projects, have to ascertain the success of these projects by making sure that the contractors do not lack skills such as the ability to facilitate projects of a high magnitude as that could lead to flawed projects. They should be constantly monitored and post evaluated. This will help to minimize the wasting of state resources.

- Description: A reaction of an acid chloride with a diamine yielded a diamide. m-Toluic acid was chlorinated to m-toluoyl chloride and subsequently reacted with 4-methyl-o-phenylenediamine in pyridine to obtain 3-methyl-N-[2-(3-methylbenzamido)phenylbenzamide (I). 2-(3-Methylphenyl)-1H-benzimidazole (II) has been obtained upon reacting o-phenylenediamine with m-toluic acid in polyphosphoric acid and toluene. The compounds have been characterized by IR, NMR, microanalyses and GC-MS. The crystal structures of the compounds have been discussed. DFT calculations of the frontier orbitals of the precursor compounds have been carried out to ascertain the groups that contribute to the HOMO and LUMO, and to study their contribution to the reactivity in the formation of the diamides and benzimidazoles. The synthesis of the amide from a diamine was seen to be favoured in the presence of a good leaving group attached to the carbonyl as in the case of acid chloride. However, the synthesis of benzimidazoles was found to be favoured in the presence of an excess of a protonating agent and high temperature.

- Description: The research study was to identify what strategies could be used by organizations in managing or containing substance abuse in the workplace. In solving the research problems, the following actions were taken: A literature study was conducted to identify the scope and impact of substance abuse in the workplace; A literature study was also conducted to identify the strategies to prevent and contain substance abuse in the workplace;The findings from the literature studies were integrated into a model of best practices for the management of substance abuse in the workplace; The model was used as a basis for the development of a survey questionnaire to determine which strategies and wellness activities the surveyed companies were using. The questionnaire survey was administered at 25 companies in Port Elizabeth. The empirical results revealed that substance abuse was common at all organizations and the size of the organization had no bearing on the extent of the substance abuse problem. The majority of the participants in the study indicated that they experienced substance abuse problems in their organizations with alcohol consumption being the main problem at these organizations. The results also revealed that companies were not doing enough in terms of education and awareness campaigns. The lack of campaigns and education material could pose a difficult challenge to deal with and could result in companies experiencing adverse performance. Another contributing factor in the prevalence of substance abuse in the workplace was that alcohol and tobacco were referred to as socially acceptable substances.

- Description: This chapter describes the use of Bhaskar’s lamination to make sense of the vast literature on collective action. The liter-ature review in the chapter was part of a broader study that in-vestigated collective action as essential for attaining the princi-ples of equity and sustainability set out in the post-apartheid South African Water Act. A laminated analysis of the literature revealed important insights such as: when dealing with collec-tive action we need to appreciate that all the levels of reality are acting simultaneously on a given context and cannot be resolved in isolation; collective action is inhibited or con-strained at different levels and scales by different things; and collective action is not suspended in a fixed context and can-not be encouraged by following a set formula. These insights point to the importance of learning to adapt as a core principle of collective action. Drawing on this research and experience of how collective action can be supported or inhibited gives insight into understanding our current limitations in supporting collective action and in understanding the kinds of collective action encounters that are occurring in catchments in South Africa. These understandings have implications for how we consider learning, and the potential contributions of learning-led change.This chapter describes the use of Bhaskar’s lamination to make sense of the vast literature on collective action.

- Description: When the apartheid government was in power universities in South Africa were segregated according to a race and language. After apartheid, the democratic government came into power and its vision was abolition of segregation. There was also equal and equity of access to public institutions which were set aside for certain people to have access to. Access to universities was equalized and students with different racial, social, cultural and linguistic backgrounds were allowed access to universities which they used not to have access to before. The students‟ access to all universities led to diversity within these institutions. Even though this was the case, there were no changes in the system prevalent during apartheid. English, for example, continued to be the language of learning and teaching (LoLT) while the numbers of students who speak languages other than English (LOTE) as home languages was also increasing. The Constitution of South Africa (Section 6, Act 108 of 1996) acknowledges the previous marginalization of indigenous languages in the country and encourages the development and use of these languages as official languages. The right of access to educational institutions, and accessing education in one‟s language, if that language is one of the official languages, is also encouraged by the Constitution. There are other supporting legislative documents such as the Languages Bill (2011), the Higher Education Act (1997) and the national Language Policy for Higher Education (LPHE) (2002) that support multilingualism, the equal promotion of the official languages as well as use of multiple languages in higher education institutions (HEIs) to support learning. The above mentioned policies and legislations may exist to ensure equality and equity, and even though HEIs have become heterogonous, that does not guarantee that the students enrolled in these institutions have equal access to knowledge offered by the HEIs in SA. This research uses the theories of languages and conceptualization; language and learning as well as language planning to show that the students‟ first languages in learning can assist to facilitate cognition. Terminology development, as part of corpus planning which is the body of language planning is introduced in this study in the form of bilingual glossaries as an intervention especially for students‟ whose mother tongue is not English as language used for learning at university for different disciplines tend to be abstract. The data for this research was collected from the 2014 first year students registered in the Extended Studies Unit (ESU) in the Humanities Faculty at Rhodes University. Research methods such as questionnaires, participant observations, interviews as well as content analysis were used to collect the data. These methods were used to look at the students‟ use and perceptions of bilingual glossaries as additional resource materials which can assist them in learning. A Political Philosophy I module offered by the Political Science department was used for this research. This thesis presents a model which can be used for the development of bilingual glossaries in order to facilitate learning. The thesis recommends the use of corpus extraction tools such as WordSmith Tools (WST) that can be used to generate and extract terms and illustrates the use of this tool by extracting terms from an English Political Philosophy textbook. These terms are defined and these are then translated into isiXhosa to provide a sample of the bilingual glossary. This glossary has been designed to illustrate how the bi/multilingual glossaries with terms and definitions can be developed in order for use by students to facilitate learning them. The study also presents a terminology list which consists of Political Philosophy terms that have been generated during the corpus extraction process. It is recommended that further research looks into the development of bi/multilingual glossaries using the suggested model so that the students who are speakers of LOTE can also be able to understand abstract terms which are used at university
