- Description: My exhibition draws on Andreas Huyssen's notion of memory sculpture to articulate my own sense of loss and trauma, due to the divorce of my parents. Within my work I explore the effects that divorce had on me and how it has disturbed my normative understanding of home and family. I have created scenarios alluding to the family home that I have manipulated in order to convey a sense of nostalgia and loss. By growing salt crystals over found objects and/or cladding them in salt, I attempt to suggest the dual motifs of preservation (a nostalgic clinging to the past) and destruction (due to the salt’s corrosive properties). In this way, the salt-crusted objects serve as a metaphor for a memory that has become stagnant, and is both destructive and regressive. The objects encapsulate the mind’s coping methods to loss. In my mini thesis, I discuss characteristics of memory sculpture as a response to trauma, drawing on Sigmund Freud's differentiation between mourning and melancholia. I also unpack how objects and traces (such as photographs) may act as nostalgic triggers, inducing a state of melancholic attachment to an idealised past. I address these concerns in relation to selected works by Doris Salcedo and Bridget Baker, and also situate them in relation to my own art practice.

- Description: The media, through development communication and edutainment, plays a critical role in the transformation of societies. In line with this, this thesis discusses the extent to which commercially driven prosocial soap operas can provide a platform for public health messaging, in the context of the HIV/AIDS epidemic in South Africa, for antiretroviral treatment (ART) and for encouraging ART adherence to foster national development. Furthermore, this thesis examined the potential of celebrities as HIV/AIDS ambassadors and the potential of both fictional characters and ‘real-life’ celebrities to disseminate these health messages. Although the HIV/AIDS epidemic in South Africa is stabilising, this is not the time to relax the communication around the disease, particularly regarding adherence to ARVs, considering that South Africa has the largest ARV rollout in the world. The qualitative methodological approach taken for this thesis is a three-step approach examining the intended message, the text and the appropriated message by viewers. Firstly, a thematic content analysis of an episode of Isidingo, that illustrated Nandipha as HIV-positive and the side-effects that came with her ART adherence, and the 3Talk interview with Lesego Motsepe, where she announced that she was weaning herself off ART, was done in order to understand the intended health messaging in the soap opera and the health message disseminated by an HIV-positive actress with regards to ART. Thereafter interview responses by the production team as well as by HIV-positive viewers, using ARVs, were thematised. In addition media texts which provided commentary on the use of a celebrity as a HIV-positive role model were examined. In doing this, this thesis has offered up the meanings of how HIV-positive women taking ARVs and living in Makana experience and understand the media, particularly health messaging relating to ARVs. The findings of this study suggest that commercial soap operas are the perfect platform to address HIV/AIDS and that prosocial health messaging regarding ARV adherence is still necessary in this country. Soap operas have the potential to have an educational angle. Although, HIV-positive individuals serve as better role models as they are authentic; given human nature, fictional characters, such as Nandipha Matabane in Isidingo, may be more sustainable role models as their message can be scientifically-based and well-researched. Realistic characters serve as role models whose behaviour is to be emulated. Soap operas appeal to a wide audience and so storylines can be tailor-made according to the times and the needs in terms of health issues and messaging. Thus, soap operas are not a single platform but rather one which can be exploited to maximum advantage for public health messaging.

- Description: Persephone’s myth is unique, as it was the central narrative of one of the most prominent ancient mystery religions, and remains one of the few (certainly the most prominent) ancient Greek myths to focus on the relationship of a mother and her daughter. This unique focus must have offered her worshippers something important that they perhaps could not find elsewhere, especially as a complex and elaborate cult grew around it, transforming the divine allegory of the changing seasons or the storage of the grain beneath the earth, into a narrative offering hope for a better place in the afterlife. To understand the appeal of this myth, two aspects of her worship and mythic significance require study: the expectations of her worshippers for their own lives, to which the goddess may have been seen as a forerunner; and the mythic frameworks operating which would characterise the goddess for her worshippers. The myth, as described in The Hymn to Demeter, is initially interpreted for its literary meaning, and then set within its cultural milieu to uncover what meaning it may have had for Persephone’s worshippers, particularly in terms of marriage and death, which form the initial motivating action of the myth. From this socio-anthropological study we turn to the mythic patterns and motifs the story offers, particularly the figure of the goddess of the Underworld (primarily in the influential Mesopotamian literature), and the Dying-Rising God figure (similarly derived from the Near East). These figures, when compared to the Greek goddess, may both reveal her unique appeal, and highlight the common attractions that lie in the figures generally. By this two-part investigation, on the particular culture’s expectations and the general mythic framework she exists in, Persephone’s meaning in her native land may be uncovered and understood.

- Description: ‘Becoming Animal’: Motifs of Hybridity and Liminality in Fairy Tales and Selected Contemporary Artworks serves as a theoretical examination of the concept of the hybrid. My research unpacks the liminal aspect of hybridity, locating the hybrid in the imaginative world of popular fairy tales, folk lore and mythology. In my accompanying MFA exhibition, Becoming(s), I explore these motifs through an installation of mixed-media sculptures which are based on the hybrid creatures that populated the fantasy world of my childhood. The written component of my MFA submission will relate directly to my professional art practise, developing it further and situating it within a relevant context. In my mini-thesis I will consider the liminal in relation to the ‘animal turn’ in contemporary art, with a particular focus on relevant artists working with the motifs of hybridity, such as Nandipha Mntambo, Jane Alexander and Kiki Smith. The ‘animal turn’ is a term used by Kari Weil (2010: 3) to describe a contemporary interest in issues of the nonhuman, and in the ways that the relationship between humans and nonhumans is marked by “difference, otherness and power”. Of key concern to my research will be Giles Deleuze and Felix Guattari’s concept of ‘becoming animal’. Rather than describing a transition from one stable state to another, ‘becoming animal’ suggests a radical dissolution of boundaries – not just between species (such as ‘human’ and ‘animal’) but between any essentialising binaries. As such, ‘becoming animal’ suggests a conception of identity as being fluid and mutable, rather than stable and fixed.

- Description: How often do we notice the buildings that we work in, play in and live in? The architecture that we construct is specially geared to our human proportions, and shelters and accommodates us. It can be seen as a metaphor for the body, the self, and systems of social control that we have created. When the structure of this architecture is compromised, either literally or metaphorically, we experience instability and vertigo. My practical submission, Vertigo is concerned with architecture, perspective, deconstruction, instability, vertigo, scale and the body. Vertigo consists of paintings, ranging in scale from the size of a brick to the height of a single storey house. Utilizing a highly representational style as well as working with abstract sign systems and technical plan drawings, I destabilize firstly, our sense of certainty in the architecture that surrounds us, and secondly, prompts us to question the assumed fixity of ourselves and our social systems, through the convergence and collision of architecture and painting. This supporting document, (Un)stable Architecture as Deconstructed Meaning, considers the key conceptual concerns informing my practical submission. In chapter one of this mini-thesis: Deconstructivist Architecture, Instability and Impermanence I look at Deconstructivist Architecture which challenges traditional values of order, stability, harmony and unity of architecture. I position my work in relation to architecture projects on the Deconstructivist Architecture show in relation to their intent of undoing, shifting and destabilizing structure and what architecture is traditionally valued for. I also look at the shifting meaning and symbolism of architecture and skyscrapers. In the second chapter: Vertiginous Point of View and Shifted Perspectives I engage with vertigo, perspective, scale and the bodily analogy in architecture. I look at how Julie Mehretu destabilises built space and architecture in a painterly way, depicting multiple perspectives which are subjected to multiple interpretations. In chapter Three: Painting a Building and Building a Painting: Process, Scale and the Body, I discuss and engage with my practical submission, Vertigo, in relation to my process, scale, the body, vertigo, deconstruction, instability and perspective.

- Description: The modern era has brought the phenomenon of organisational change closer to the average person. With the recent financial crisis placing more strain on businesses, organisations are always under pressure to review their business models in order to deliver a sustainable operational model and as result, hopefully a sustainable competitive advantage. In order to remain competitive, the leadership team has to constantly seek ways of differentiating their organisations from others with similar product offerings. When these changes are initiated, there is no doubt that the leadership gave extensive thought prior to execution. However, their motives are not always clear to their most important constitution, their employees. Often when these changes are implemented, employees believe that they’ve been left out of the decision making process. Furthermore, post change review with employees are also not given enough thought and are often not done. This research used qualitative research methods to establish how employees experience job satisfaction and organisational climate subsequent to changes that transpired within their work environment. Semi-structured interviews and document analysis were used to collect data. The interviews were constructed by expanding upon well-documented quantitative dimensions of these behavioural variables. Questions were developed focusing on these dimensions in line with the changes experienced. The sample consisted of nine employees at an employee wellness organisation in Roodepoort, Gauteng. There is evidence to show that in this short period of two years (May 2012 to June 2014), by implementing various changes, the new leadership has improved the financial viability of the organisation. However, insights from the interviews point to a number of areas where the leadership and management structures have to exert more effort. Communication processes have to be reviewed, especially to lower levels. As there exists limited opportunities for promotion, investigations into expanding existing roles, again at the lower levels may assist in raising job satisfaction levels. Employees felt that support structures are severely lacking when significant changes affecting them are implemented. A climate for innovation and risk taking has to be considered which, if instituted, could aid the organisation in setting the pace for the organisational wellness industry. The structure adopted for this research consists of three sections. Section one follows the evaluation report format, with the literature review and research methodology sections following thereafter. By making use of established literature as a basis, the findings and recommendations are therefore not exclusively applicable to this organisation. Hence other organisations intending similar change initiatives could benefit from this research.

- Description: This case study was written within the broader concept of Organisational Culture and how it is integrated into an organisation to encourage responsible leadership. The core focus and emphasis of this approach is to establish the implications for businesses operating in the most challenging of commercial environments, while adhering to their corporate ethos and organisational values. These may be summarised with the phrase: Only a clean business is a sustainable business. This dissertation is intended to act as a case study and resource aide for the teaching of leadership, organisational behaviour, human resources and business sustainability. The study is about the Afghanistan chapter of the global giant Siemens, which has been working in many areas of specialisation conducting business in the country for more than 75 years. It has been selected for this case study because of its long-term impressive record, during which time it has developed and sustained a reputation as an organisation with a much-admired organisational culture, and one to which employees feel very closely attached and connected. This case study evolved from a set of unique as well as difficult circumstances. In Afghanistan, where infrastructure is weak, businesses and other structured organisations are in their initial and immature stages of development, and employee attachment to their workplaces is relatively weak. In the case of Siemens however, it has been much the opposite. It became apparent over a protracted period of time that the relationship of employees to the company was clearly of a positive and committed nature, unlike the general perception stemming from other multinational organisations operating within the country. Many business organisations in Afghanistan tend to emphasise to a lesser degree some modern-day practices of employer-employee relationships, which negatively affect motivation and commitment. The study grew out of the observations that employees of Siemens on the other hand, seemed to exhibit attitudes and commitments contrary to the general trend in the wider business sector. This project began with the intention to identify those factors contributing to employee loyalty and strong attachments to an organisation. Subsequently, the same findings were used to identify the traits and particular features working within the organisational environment.

- Description: The central argument of this inter-disciplinary study is that IsiXhosa written poetry of 1912 – 2012 is a terrain of the struggle between the contending dominant ideologies of Segregation, Apartheid and Charterism (post-Apartheid); and the subordinate/ subaltern ideologies of Africanism, Charterism (pre-democracy), Pan- Africanism, Black Consciousness Movement and other post Apartheid ideologies. The study highlights the mutual relationship between the text and the context by focussing on the ideological contest which manifests itself in both form and structure (i.e. aesthetic ideology) and the content (i.e. authorial ideology) of the poetry of different epochs between 1912 and 2012. The study is located within the framework of Antonio Gramsci’s theory of cultural construction. Gramsci postulates that ideology and culture play a significant role in the process of asserting hegemony. Important concepts that constitute Gramsci’s theory of praxis are: ideology, culture, hegemony, organic intellectuals and both ideological and repressive state apparatuses. The first chapter presents the problem, the objectives, the methodology, and the scope of the study. The second chapter presents Gramsci’s theory of cultural construction and the work of scholars who developed his theory further. The tool that is employed for analysis and interpretation of textual significations of IsiXhosa written poetry is the revolutionary aesthetics, which is proposed by Udenta. The third chapter analyses and interprets literature of the epoch of 1912-1934 and exposes the contest between Segregation and Africanism ideologies. The fourth chapter contextualises and analyses the literature of 1934 – 1948, the second phase of contestation between Segregation and Africanism. The fifth chapter deals with literature of the first and second halves of the Apartheid epoch (1948 - 1973). The Apartheid ideology contested with the Africanist ideology which transformed into the Charterism ideology in 1955. In 1960 Pan-Africanism ideology and in 1969 Black Consciousness Movement ideologies entered the contest. The sixth chapter examines literature of the period 1973 – 1994 which is the second phase of the Apartheid epoch that ends with the “glasnost” period of 1990 - 1994. The seventh chapter studies literature of the democracy period of 1994 – 2012. The eighth chapter is the summary and general conclusion. The illumination of the nexus between culture and ideology during the past century (1912 - 2012) will provide insights that will assist us in addressing the challenges we face during the democracy period, and in the development on Arts and Culture in general, and literature in particular

- Description: The international financial environment has become riskier due to the recent developments in product offerings and failure of regulation to keep abreast with these changes. The Global Financial Crisis exposed inadequacies of regulation, thus consensus on the need for comprehensive and uniform regulation was made by G-20 member states. Imposing exchange trading, clearing, reporting and capital requirements on the derivatives market are some of the ways of dealing with the problems caused by lax regulatory oversight. In this study, through the comparative analysis of derivatives regulation in South Africa, Brazil, India and Turkey, it was established that emerging countries are taking active steps to implement the G-20 agreement. Uniformity in the core rules was noted, with differences in the supportive legislation. Country specific rules which support the macroeconomic factors that are faced by these countries and the infrastructure available for regulatory execution are used amongst countries. The study concluded that current regulation in emerging countries is accommodative and regulatory differences are in line with economic factors in each country.

- Description: This study researched the nature of tasks used in Grade 10 mathematics tests and end-of-year national examinations. The study was carried out in three, purposively selected, Grade 10 schools in the Ohangwena region in Northern Namibia. For the purpose of this study, a mixed method approach was employed to analyse a combination of both quantitative and qualitative data. A sample of three tests per mathematics teacher from the three participating schools and national examinations question papers for the past three consecutive years (2011-2013) were analysed using Stein, Smith, Henningsen, & Silver’s (2000) framework of cognitive demand. The study was divided into two phases. Phase 1 was the analysis of teacher test items and national examination items in terms of their cognitive demand. Phase 2 involved semi-structured interviews with three selected teachers to probe their views and find out their basis for selecting test items. The findings of this study revealed that there was no substantial difference in the distribution of the levels of cognitive demand in both tests and national examinations items. The study, however, showed that mainly tasks requiring only procedures without connections dominated the tests and the examinations. The number of higher level tasks in both tests and examinations analysed was low. There was no single task coded at level 4 in any of the teachers’ tests. Only 2% of tasks could be classified at level 4 in the examination items. The study also revealed that since tests and examinations assess the same learning objectives from the syllabus, most of the test items set by teachers were extracted from the national examinations question papers. The paper recommends that more tasks at a higher level category need to be included in assessment tasks to promote critical thinking amongst learners.

- Description: Scrutiny of the capabilities and accuracy of computer forensic tools is increasing as the number of incidents relying on digital evidence and the weight of that evidence increase. This thesis describes the capabilities of the leading proprietary and open source digital forensic tools. The capabilities of the tools were tested separately on digital media that had been formatted using Windows and Linux. Experiments were carried out with the intention of establishing whether the capabilities of open source computer forensics are similar to those of proprietary computer forensic tools, and whether these tools could complement one another. The tools were tested with regards to their capabilities to make and analyse digital forensic images in a forensically sound manner. The tests were carried out on each media type after deleting data from the media, and then repeated after formatting the media. The results of the experiments performed demonstrate that both proprietary and open source computer forensic tools have superior capabilities in different scenarios, and that the toolsets can be used to validate and complement one another. The implication of these findings is that investigators have an affordable means of validating their findings and are able to more effectively investigate digital media.

- Description: The role of natural resources in African conflicts has been subject to extensive scholarly analysis. However, much of this analysis has taken a narrow economic reductionist bias. As such, it is imperative that the dominant assumptions and accepted concepts and theories about the role of natural resources in African conflicts be re-examined. The aim of this thesis is to offer a revaluation of the role of coltan during the Democratic Republic of Congo’s (DRC) Second War (1998-2003) through a critical engagement with the resource wars literature. The purpose is to offer a re-reading of the role of coltan in the DRC Second War and the broader regional and global economic context in which this conflict took place. It rejects the commonly cited assumption that the presence of coltan in the DRC means it is an initiator of conflict. Rather, this thesis argues that the central role of coltan in the DRC Second War was as an aggravator of conflict in that its exploitation was used by different parties to fund their military and political ambitions. This thesis also argues that the DRC’s weak state structures and pivotal role within the Great Lakes region, as well as the international trade of coltan and the nature of the DRC coltan mining industry are all key factors in understanding coltan exploitation in the country’s Eastern Region during the Second War.

- Description: South African history is rooted in racial identities, inequalities and injustices, which the post-apartheid government has sought to address for twenty years since 1994. The transition to a post-apartheid society though has been a difficult one with the social structure and everyday life still marked by the racial past. Though racial classifications on an official basis no longer exist, racial identities continue to pervade the country. Of particular significance to this thesis are black identities including the possibility of black inferiority, which I examine in relation to black post-graduate university students in contemporary South Africa, specifically at Rhodes University. In examining this topic, I draw extensively on the work of Frantz Fanon, who wrote about both colonial society and the emerging post-colonial experience. Fanon was a young black intellectual whose work was in part based on his own experiences of being a once-colonised black person in a world which he perceived as being dominated by whiteness. In his work he expresses his own perceptions of whiteness and how the black identity has come to be shaped by and around this dominant white foundation. Fanon extensively discussed the lives of black intellectuals and elites, and demonstrated how the black identity becomes shaped by and around the world of whiteness. In doing so, he raised a range of themes, such as black inferiority, mimicry and double consciousness. I draw upon the work of Fanon in a critically sympathetic manner to delve into the experiences of black postgraduate students as they negotiate their way through a university setting dominated by a white institutional culture. I bring to the fore the argument that the racial identities of these students is not fixed and sutured but, rather, is marked by considerable fluidity and ambiguity such that black identity must be understood not just as a state of being but also as a process of becoming.

- Description: Forested areas have been cited for their highly diverse floral and faunal assemblages, which are currently under threat from anthropogenic activities that restrict their range and deplete the resources produced within these naturally fragmented patches. Historically, up to 67 percent of avifaunal species associated with well-treed areas have undergone localised extinctions, consequentially affecting biodiversity as a measure of species richness and ecosystem functionality. To date, more than 900 of the bird species affiliated with forests are under threat and despite the theory surrounding functional redundancy, the mass extinction that is currently underway poses considerable limitations on the ecological integrity of these biomes. In South Africa, indigenous forest (one of the rarest biomes), occurs predominantly in small isolated patches along the eastern escarpment. With mountainous terrain emphasised as ‘prominent hotspots of extinction’, the limited dispersal and habitat sensitivity of montane forest fauna renders these species more prone to localised extinctions. BirdLife International, the IUCN and SABAP2 all indicate reductions in the range and abundance of the Chorister Robin-Chat (Cossypha dichroa) - an endemic forest specialist that is reported to move seasonally between high-altitude forest patches where they breed in summer, and lowland coastal forests where they overwinter. Beyond diet, body morphology and vocalisations, much of the information available on the altitudinal movements of C. dichroa is based on secondary sources and the assumptions therein. This study aimed to investigate the potential utilisation of δ13C and δ15N stable isotopes in determining the dietary niche width and altitudinal movements of C. dichroa. Feathers obtained in forested patches of the Limpopo, KwaZulu-Natal and Eastern Cape provinces exhibited a wide trophic niche width and generalised diet. Strong regional separation is apparent in the isotopic signatures suggesting little movement between provinces. A comparison of 13C-isotopes showed minimal variation that point to a uniformity in the carbon-base utilised by C. dichroa across their range. The 15N-signatures obtained in Limpopo, however, revealed a distinct trophic segregation between the northern-most Chorister populations and their southern counterparts. No altitudinal movements were detected in the isotopic signatures of recaptured Choristers, but more research is needed to investigate the long-term accuracy of these results and the breeding potential of resident Choristers in lowland coastal forests; especially when considering the reduced range and abundance reported for this endemic species.

- Description: The proliferation of the Internet has amplified the use of social networking sites by creating a platform that encourages individuals to share information. As a result there is a wealth of information that is publically and easily accessible. This research explores whether open source intelligence (OSINT), which is freely available, could be used as a digital forensic investigative tool. A survey was created and sent to digital forensic investigators to establish whether they currently use OSINT when performing investigations. The survey results confirm that OSINT is being used by digital forensic investigators when performing investigations but there are currently no guidelines or frameworks available to support the use thereof. Additionally, the survey results showed a belief amongst those surveyed that evidence gleaned from OSINT sources is considered supplementary rather than evidentiary. The findings of this research led to the development of a framework that identifies and recommends key processes to follow when conducting OSINT investigations. The framework can assist digital forensic investigators to follow a structured and rigorous process, which may lead to the unanimous acceptance of information obtained via OSINT sources as evidentiary rather than supplementary in the near future.

Quantitative Au, Ag, Hg, and Cu data are presented for gold grains from eleven sites. Additionally, quantitative Te, W, As, and Sb trace element data are presented for gold grains from ten of the eleven sites. Although it is acknowledged that quantitative trace element analysis of gold grains is a relatively new endeavour, the limited trace element data obtained in this study suggest that trace element analysis could be useful for characterising gold sources on the southern Seward Peninsula. Major and minor element geochemical profiling is sufficient at differentiating between sites from regional provenance systems but insufficient at differentiating between sites within a single system. Differentiating among sites within a single system will likely require microchemical analysis of mineral inclusions and analysis of trace element signatures.

- Description: A new light-emitting-diode based pulsing system for measurement of time-resolved luminescence has been developed. The light-emitting-diodes are pulsed at various pulse-widths by a 555-timer operated as a monostable multivibrator. The light-emitting-diodes are arranged in a dural holder connected in parallel in sets of four, each containing four diodes in series. The output pulse from the 555-timer is fed into an 2N7000 MOSFET to produce a pulse-current of 500 mA to drive the set of 16 light-emitting-diodes. This size of current is sufficient to drive the diodes with each driven at a pulse-current of 90 mA with a possible maximum of 110 mA per diode. A multichannel scaler is used to trigger the pulsing system and to record data at selectable dwell times. The system is capable of generating pulse-widths in the range of microseconds upwards.

- Description: In 2010, the Financial Services Regulatory Authority (FSRA) of Swaziland noticed a significant increase in employee absenteeism which they discovered was related mainly to: poor health (sick leave), personal and financial stress (garnishee orders were increasing), and low staff morale, the consequence of which was low productivity and missed deadlines (FSRA, 2010:7). High levels of absenteeism meant that a sizeable number of employees were unable to complete their daily tasks (FSRA, 2010:7). Consequently, in 2011, the FSRA Human Resource Department started a wellness programme for all employees in the organization in an attempt to respond to the human resource challenges reported in 2009/10 financial year. By the end of 2012, FSRA management reported that the introduction of the EWP had not yielded the expected results. This therefore prompted management to request an evaluation of the FSRA employee wellness programme. The aim of this research was to identify and prioritize the needs of employees in terms of requirements of a wellness programme and how it should be delivered. The specific objectives of the study are as follows: to identify the wellness needs of employees, to identify employee preferences in terms of the type of interventions to be included in a wellness programme, to identify the preferred mode of delivery of the wellness programme and to make recommendations to management on the design of a wellness programme. Questionnaires with closed ended questions were used to collect data for this survey. The questionnaire used is attached as Appendix A. By means of a needs analysis survey, this research was designed to assess the FSRA employees’ needs in terms of an employee wellness programme, as well as the preferred EWP delivery methods. About 70 percent of FSRA employees participated in the survey. The respondents completed the questionnaire and submitted it online over a period of 10 working days (2 weeks). This report is structured into three sections, namely; section one, which is the evaluation report that gives details of the importance of the study, highlights research methods and then present the results, discussions and recommendations. Section two deals with the literature review while section three reports on the research methodology, research design and procedures and the limitation of the study. In light of the findings on the wellness needs of employees, 72 percent of the respondents felt the current wellness programme was very inadequate and a further 10 percent added that it was inadequate in addressing their wellness needs largely because the needs were not known. The most important wellness needs identified included: exercise, nutrition, personal hygiene, disease awareness and treatment of illness, coping with stress, coping with workload, ventilation, safety, bereavement, personal debt, and retirement planning. The most preferred wellness interventions that respondents proposed include Flexible Work Schedule, Safe Workplace, Improved Ventilation, Retirement Planning Advice and Gymnasium. Further analysis done using correlation analysis indicated that there was a significant positive relationship between the wellness needs and the wellness interventions. Concerning the delivery of the wellness programme, most of the employees indicated that outsourcing certain services was better than having them in house. The highest ranking of the services for out sourcing were nutrition education and medical checkups that ranked between 82 percent and 75 percent respectively. The respondents indicated that they want almost all the chosen interventions to be outsourced. Time slots should also be taken into consideration to ensure employee participation in the wellness programme services. The respondent FSRA employees seem to prefer interventions of an educational nature to be during the lunch hour. These include Nutrition Education, Health Education, Hygiene Education and Medical Check ups and Treatment, whereas Gymnasium was preferred to be after working hours.

A sociological analysis of the production, marketing and distribution of contemporary popular music by Zambian musicians

- Description: The purpose of this research was to gather information about the production, marketing and distribution of Zambian contemporary music by Zambian musicians. Very little information has been documented about the development of the Zambian music industry, particularly from the perspective of those within the industry. As a result this study attempted to add to this knowledge. To achieve this Pierre Bourdieu’s theoretical concepts of ‘fields’ and ‘habitus’ were used to gain an understanding of what affects the creation of art forms such as music as well as the structures and underlying processes within the music industry. The concept of ‘fields’ usefully framed an explanation of the struggles and connections within the various fields in the industry and a view of the Zambian music industry in relation to the international industry. To gather the data necessary for this research a qualitative approach was utilised involving semistructured in-depth questionnaires from twenty-three interviewees. These interviewees were selected from various sectors of the music industry in an attempt to gain a holistic perspective of the industry in the 21st century. There were four subgroups: the artists (singers, rappers and instrumentalists), managers, radio DJs, and a miscellaneous group made up of the remaining participants, a Sounds Arcade manager, a music journalist, the National Arts Council Chairperson, a Zambia Music Copyright Protection Society (ZAMCOPS) administrator, and the then President of the Zambia Association of Musicians (ZAM). With the limited exposure to formal musical, instrumental and production training, musicians, instrumentalists, managers and studio production personnel interviewed had had to learn their craft on-the-job. This limited knowledge appears to add to the hindrance of the development of careers and the industry, particularly in terms of how to register and distribute music correctly to earn royalties and protect their intellectual property against piracy. From an institutional level piracy is being addressed more forcefully with the introduction of holograms and the tightening of policies and structures to do with the music industry.
