- Description: Mitochondria are key to eukaryotic cell survival and their activity is linked to generation of reactive oxygen species (ROS) which in turn acts as both an intracellular signal and an effective executioner of cells with regards to cellular senescence. The mitochondrial molecular chaperone tumor necrosis factor receptor associated protein 1 (TRAP1) is often termed the cytoprotective chaperone for its role in cancer cell survival and protection from apoptosis. Here, we hypothesize that TRAP1 serves to modulate mitochondrial activity in stem cell maintenance, survival and differentiation.

- Description: Even if all the technical security solutions appropriate for an organisation’s network are implemented, for example, firewalls, antivirus programs and encryption, if the human factor is neglected then these technical security solutions will serve no purpose. The greatest challenge to network security is probably not the technological solutions that organisations invest in, but the human factor (non-technical solutions), which most organisations neglect. The human factor is often ignored even though humans are the most important resources of organisations and perform all the physical tasks, configure and manage equipment, enter data, manage people and operate the systems and networks. The same people that manage and operate networks and systems have vulnerabilities. They are not perfect and there will always be an element of mistake-making or error. In other words, humans make mistakes that could result in security vulnerabilities, and the exploitation of these vulnerabilities could in turn result in network security breaches. Human vulnerabilities are driven by many factors including insufficient security education, training and awareness, a lack of security policies and procedures in the organisation, a limited attention span and negligence. Network security may thus be compromised by this human vulnerability. In the context of this dissertation, both physical and technological controls should be implemented to ensure the security of the SANReN network. However, if the human factors are not adequately addressed, the network would become vulnerable to risks posed by the human factor which could threaten the security of the network. Accordingly, the primary research objective of this study is to formulate guidelines that address the information security related human factors in the rolling out and continued management of the SANReN network. An analysis of existing policies and procedures governing the SANReN network was conducted and it was determined that there are currently no guidelines addressing the human factor in the SANReN beneficiary institutions. Therefore, the aim of this study is to provide the guidelines for addressing the human factor threats in the SANReN beneficiary institutions.

- Description: This mini-thesis is a supporting document to the exhibition titled via: a phenomenological site-specific series of intermedia interventions and installations at the 1820 Settlers National Monument in Grahamstown. This mini-thesis examines ways in which one negotiates the movement of the self and interactions with others within the non-place. Non-places are ‘habitually transient’ spaces for passage, communication and consumption, often viewed from highways, vehicles, hotels, petrol stations, airports and supermarkets. Characteristic of these generic and somewhat homogenous spaces is the paradox of material excess and concurrent psychological lack where a feeling of disorientation and disconnection is established due to the excesses of Supermodernity: excess of the individual, time and space. The non-place is a contested space as it does not hold enough significance to be regarded as a place and yet, despite its banality, is necessary – and in many ways a privilege – in everyday living. I explore the concept of non-places in relation to the intricate notions of space and place, and draw on empirical research as a means to interrogate how one perceives the phenomenological qualities of one’s surroundings. I discuss the implications of the multiplication of the non-place in relation to globalisation, time–space compression, site-specific art and absentmindedness, as theoretical themes which underpin the practical component of my research. In addition, I situate my artistic practice in relation to other contemporary artists dealing with the non-place as a theme, and critically engage with the multi-disciplinary and sensory installations and video pieces of Belgian artist Hans Op de Beeck.

- Description: publisher version , The potential for national pride to take on shades of both the authentic and the hubristic is reflected in the International Social Survey Program's (ISSP) use of two different multi-item measures of national pride, a general and a domain-specific one. In contrast, domain-specific national pride is characterized as 'not overtly nationalistic, imperialistic, nor chauvinistic' and is expressed as positive feelings towards national accomplishments in a range of domains including arts, science and sport. Most scholars who take an interest in the impact of sport mega-events acknowledge that national pride is related to concepts such as patriotism and nationalism whose meanings are difficult to disentangle. The South African Social Attitudes Survey (SASAS), which has tracked the attitudes of South African adults around the 2010 World Cup, has confirmed this idea. The longitudinal SASAS study found that subsequent to the event, there was an enormous upswing in the belief that the World Cup had a positive impact on social cohesion.

- Description: This paper examines how SES relates to individual happiness, while also controlling for family functioning; the latter measured by the Family Attachment and Changeability Index 8 (FACI8). An individual-, household-, and subjective SES index are developed via multiple correspondence analyses (MCA). Using data from the 2012 South African Social Attitudes Survey (SASAS), the paper employs structural equation modelling (SEM) to explore the relationship between happiness, SES, and family functioning. Multiple-group SEM (MGSEM) is employed to examine the association between happiness and family functioning across quartiles of the three SES indices. The results reveal that higher SES is significantly related to greater happiness, with the role of household- and subjective SES being stronger than individual SES. Furthermore, improved levels of family changeability are positively associated with happiness, whereas there is no relationship between happiness and family attachment. Overall, levels of family changeability and individual happiness are likely to benefit from improvements in socioeconomic status.

- Description: While South Africa stands apart from other countries as being more progressive in terms of gay and lesbian rights, attitudes towards this population continue to be intolerant. Attitudes shape people’s behaviour and in a university setting young students are vulnerable to discrimination. This is often a time when young people are still shaping their identities. An electronic survey comprising the Attitudes towards Lesbians and Gay Men Scale was administered to 401 students taking undergraduate psychology courses at the East London Campus of the University of Fort Hare, to assess their attitudes towards gays and lesbians. The survey measured their attitudes in terms of the biographical variables of gender, age, race, and religiosity, commitment to religious practice, urban or rural upbringing and nationality. The results of the research found that gender, race, religiosity, religious attendance and rural or urban upbringing do influence students’ attitudes significantly. However, age did not have an effect on attitudes towards gays and lesbians in the present study. The significance of the differences in attitudes in terms of nationality was not able to be tested due to the small sample size of foreign students. The findings of this study show that there are fairly consistent predictors of students’ attitudes concerning gays and lesbians. This information can help us to clarify areas to target for improvement in the campus climate for gay and lesbian communities.

- Description: The HIV and AIDS pandemic have become not only a health concern but educational and social concern as well. According to Beyers and Hay (2011, p. 99) many school-going children are not only affected by HIV but a large number of adolescents are also either HIV positive or have AIDS. Other researchers argue that education should act as a vaccine against new HIV infections (Kendall and O’Gara, 2007, p. 6). This argument comes with the expectation that all teachers are willing and ready to work with learners made vulnerable by HIV and AIDS; without considering the lived realities of the teachers in relation to HIV and AIDS. While many teachers make a difference in the lives of affected and infected learners through the way in which they deal with the learners concerned, some may not take up the challenge to assist the learners, while others might unknowingly and unintentionally do harm. This study, therefore, aimed at exploring high school teachers’ experiences of working with learners made vulnerable by HIV and AIDS in order to generate guidelines to assist teachers to effectively deal with vulnerable learners in their classrooms.

This article presents a case study of higher education research by considering a newly formed Higher Education Studies doctoral programme. The programme comprises 29 PhD scholars in 2014, all engaged in research on some aspect of higher education. The description of the PhD programme, the PhD scholars and what their research topics are, reveals a picture of the broad range of concerns within the field of Higher Education Studies and suggests that the field is a region, in Bernstein's terms. This means that it draws on multiple disciplines and looks both to the values and structures of those disciplines and to the professional world of work. It is argued that the strengthening of the epistemological base of Higher Education Studies is necessary for higher education research to move forwards with enhanced relational and positional autonomy.

- Description: Epizootic ulcerative syndrome (EUS) is a fish disease caused by an infection of the oomycete, Aphanomyces invadans. During a fish biodiversity assessment of Lake Liambezi, Zambezi Region, Namibia, in August 2011, two Barbus haasianus and three Barbus unitaeniatus with circular ulcerative skin lesions were collected. Lake Liambezi receives inflow from the Zambezi, Chobe and Linyanti rivers. The presence of EUS in the two species was confirmed histologically by: a loss of epidermis at the site of the lesion; hyphae visible deep into the muscle layer with an associated granulomatous inflammatory reaction; and muscle fibre degeneration visible with associated penetrating hyphae. This paper provides further histological confirmation of EUS from Lake Liambezi and the first record of the disease in B. haasianus.

- Description: Trees in urban areas are important sources of ecosystem services and benefits. In most towns the bulk of urban biodiversity, and trees specifically, are found in homestead gardens. But there is only limited understanding of the tree holdings in such gardens, and how they vary within and between towns, especially for developing countries where rapid urbanisation and high poverty influence the use of and reliance on land and local resources. We report on the nature of tree holdings in private gardens of poorer suburbs in three medium-sized towns along a gradient of decreasing mean annual rainfall in northern South Africa. A total of 3 217 trees were enumerated across 450 randomly selected homesteads. Most (90 %) households had at least one tree on their homestead, with an average of 7.7 ± 6.1 trees. Most householders had planted the trees themselves. The density of trees declined along the moisture gradient. Within towns, tree density was positively related to garden size, which in turn was related to relative affluence and age of the suburb. Newer and poorer suburbs had the fewest trees per household. Sixty-two tree species were recorded, which were dominated by alien species, especially fruit trees. There was no relationship between the moisture gradient and tree species richness per household, but within towns there was a difference between suburbs, being lowest in the newest suburbs. Numbers of trees and species per household was positively related to age of the household head.

- Description: Kalaharituber pfeilii (Henn.) Trappe & Kagan-Zur commonly known as the “Kalahari truffle” is a desert truffle species identified from the Kalahari region of southern Africa. Two other species, Eremiomyces echinulatus (Trappe & Marasas) Trappe & Kagan-Zur and Mattirolomyces austroafricanus (Trappe & Marasas) Trappe & Kovacs are also known to occur in other parts of southern Africa. Truffles are hypogeous fruiting bodies of Ascomycetes, important to humans for their nutritional value and medicinal characteristics. These truffles are known as desert truffles as they prefer to occur under arid or semi-arid conditions characteristic of deserts. Truffle development depends on the presence of a mycorrhizal host, associated microorganisms as well as soil and climatic characteristics. It has been suggested that K. pfeilii has a suspected broad plant host range which includes herbaceous to woody trees and shrubs. However, these relationships have not been verified. Indigenous people of the Kalahari believe that truffles are found under grasses. In the Kalahari, truffle fruiting bodies are often found entangled in Stipagrostis ciliata (Desf.) De Winter var. capensis (Trin. & Rupr.) De Winter roots. S. ciliata, also known as the tall bushman-grass, is the most common grass found in the Kalahari. The objective of this study was to provide conclusive evidence that S. ciliata var. capensis is a host of the Kalahari truffle. Truffle fruiting bodies and grass roots from where the truffles were found were collected from Upington, South Africa. The fruiting bodies were identified by observing their morphological characteristics using the ‘Keys of Truffle genera’. All observed physical properties were similar to those of K. pfeilii and further identification was done using molecular techniques. DNA was extracted from the fruiting bodies, mycelial cultures, rhizosheaths and from the S. ciliata var. capensis grass roots, which were then amplified using the specific K. pfeilii specific primers TPF3 and TPR1 and sequenced. The obtained sequence results confirmed that the collected fruiting bodies were those of the K. pfeilii and the molecular techniques also confirmed that K. pfeilii DNA was present in the S. ciliata var. capensis rhizosheath and root cells. Microscopy showed an ectendomycorrhizal association between K. pfeilii and S. ciliata var. capensis. Mycorrhizal resynthesis experiments were conducted to establish this mycorrhizal association in-vitro. They were unsuccessful because of the structure of the grass and the availability of contaminants. And more...

- Description: Kalaharituber pfeilii (Henn.) Trappe & Kagan-Zur commonly known as the “Kalahari truffle” is a desert truffle species identified from the Kalahari region of southern Africa. Two other species, Eremiomyces echinulatus (Trappe & Marasas) Trappe & Kagan-Zur and Mattirolomyces austroafricanus (Trappe & Marasas) Trappe & Kovacs are also known to occur in other parts of southern Africa. Truffles are hypogeous fruiting bodies of Ascomycetes, important to humans for their nutritional value and medicinal characteristics. These truffles are known as desert truffles as they prefer to occur under arid or semi-arid conditions characteristic of deserts. Truffle development depends on the presence of a mycorrhizal host, associated microorganisms as well as soil and climatic characteristics. It has been suggested that K. pfeilii has a suspected broad plant host range which includes herbaceous to woody trees and shrubs. However, these relationships have not been verified.

- Description: It is broadly accepted that there is a need for better security management and protocols for hostage incident management, there is currently a lack of basic empirical knowledge about the existing security management protocols with reference to existing policies, knowledge and the capability of International Non-Governmental Organisations (INGOs) to handle hostage incidents. Many INGOs have successfully managed high-profile hostage crises, but there is still a considerable level of uncertainty about the way these crises have been solved and the way their success can be seen in relation to other crises. This study aimed to understand how INGOs prepare themselves for hostage incidents, whether policies, procedures are in place, how they manage hostage situations, and also how INGO staff are trained and prepared. The methodology adopted for this study was qualitative and comprised of indepth interviews with sixteen INGOs and ten industry experts and a review of INGO documents, policies and plans. The study sheds light on some of the less talked-about aspects for INGO security management in general, as well as preparedness and responsibility towards their staff. The study suggests that while most organisations have a level of preparedness in place, enhancing each agency’s respective policies may assist the organisation in better management. The study also found that there is a higher use of ransom payment than expected, and that there is an increasing willingness to engage external expertise to assisting in managing a hostage crisis. The study makes several recommendations that may have policy implications, including pre-deployment hostile environment training, reviewing potential cooperation between INGOs and United Nations, and the use of external resources to assist in managing a hostage crisis. It also recommends a revision of existing negotiation models, as the current models are lacking in addressing protracted hostage cases. The establishment of an accurate database of incidents to allow for improved interpretation of trends and scope of hostage cases is also recommended.

- Description: The housing delivery topic is frequently dredged to the surface of media focus by tragic phenomena such as the destruction of lives and properties by storms and fires and also at the hands of the police during demonstrations. This study which is exploratory in nature and adopted an interpretive research philosophy aimed at investigating the housing delivery challenges encountered by Ekurhuleni Metropolitan Municipality (EMM) with the objectives of illuminating the challenges, establishing the role EMM play in housing delivery and providing recommendations that would assist in ameliorating the challenges. It utilised a qualitative methodology involving indirect observation which included the use of questionnaires and interviews and a purposive sampling method where fifty eight participants comprising employees of EMM, Councillors, Community leaders and Community members were selected. The data were analysed in Microsoft word using thematic analysis and a pilot study was used to pre-test the objectivity, reliability and validity of the data and also to improve the success and effectiveness of the investigation. Overall, the results suggested the main causes of the housing delivery challenges to be predominantly a combination of population growth, the unavailability of land, corruption and government policies. The key findings that emerged for the amelioration of the challenges were the formulation of a coherent housing strategy, the need for the government to pursue housing policies that are comprehensive and effectively integrated with broader socioeconomic objectives and also the need for the government to be fully attuned to the necessity of reconfiguring housing policy as part of its mechanism for managing the economy. The general focus of the recommendations was on overcoming the housing delivery hurdles. In recommending future research, the existence of a vast amount of new knowledge that still need to be discovered on the housing delivery arena was established and avenues were indicated through which the knowledge can directly illuminate issues central to the theme of this study [housing delivery challenges]. The study will become a landmark and a standard reference in future studies wherein it will also serve as a barometer to test new and contentious ideas and theories encapsulated in issues surrounding the study.

- Description: The increase in teenage pregnancy among school going learners is reported in the media as a crisis. Politicians and other stakeholders have also raised their views and concerns about pregnancy. In particular, these views and concerns perceive teenage pregnancy among school going learners as a cancer that needs a remedy because it has negative consequences for the learners, in particular the girl child. However, for all the sense of public crisis concerning sexuality and schooling, the voices of young people themselves regarding their own sexual subjectivity are seldom heard. This study focused on how girls in a former model C all girls high school negotiate and make sense of the meaning of the messages that they receive from the formal curriculum. The concept of student sexual cultures was employed in this study. Student sexual cultures are the informal groups that exist in the school and the girls take part in it. It is in these groups that the girls learn about sexuality and also make sense of their own gendered identities. This study employed ethnographic techniques of classroom observation coupled with in-depth interviews, focus groups and solicited narratives in order to understand how the participants experience and "take up" the messages they receive in the formal sexuality education component of the Life Orientation (LO) curriculum. The data was collected over a period of three months and was analysed using a directed content analysis. Four dominant themes emerged from the study. Firstly, the data reveals the school is a space of competing and conflicting discourses of sexuality and the learners are involved in a constant negotiation of the meanings of the messages. Secondly, the data shows the contested and confirmations of learners subjectivity. It shows that learners are regarded as sexual beings both in the formal and informal school cultures but there are limitations around one's sexual subjectivities. Thirdly, the data reveals that the school is a site in which a variety of femininities are reproduced, contested and struggled over. Femininities are constructed in the complex context of the school thus the school emerges as a site in which multiple femininities intersect with class, race and sexuality. Lastly, this study argues for the incorporation of the discourse of erotics in the formal curriculum which allows young people's voices to be heard. This approach (discourse of erotics) can be seen as a process of becoming, which focuses on possibilities of improving sexuality education as opposed to an imposed sexual model that is applied to young people and assumed to be the solution to young people's sexuality.

- Description: In South Africa, the right to protest is under constant threat as a result of the state response. Increasing cases of forceful policing and sometimes unlawful procedural prohibitions of protest attest to this. This study aims to firstly describe this situation through securitisation theory, essentially arguing that South Africa has become a securitised state. It also aims to understand how this is sustained by the state and why the state needs to use a securitised response to maintain power. Interviews were conducted with members of different communities and organisations. Their responses helped to illustrate the frustration of the right to protest or brutal policing during a protest. This provided primary evidence to support the claims of the study. The research shows that claims to protest are being delegitimised under the guise of security as protestors are being constructed as threats to the state. This is further substantiated by looking at how the reorganisation and remililtarisation of the South African Police perpetuates the criminalisation of protestors which necessitates a forceful response from the state. Furthermore, it shows that there is a distinct relationship between the prohibition of protest and the recent increase in ‘violent’ protests which legitimate forceful policing thereby creating a state sustained cycle of violence. The larger implication of this treatment is that these protestors are treated as non- citizens who are definitively excluded from participating in governance. In understanding why this is taking place, it is clear that a securtitised response is an attempt to maintain power by dispelling any threats to power, a response which is seen to have a long history in the African National Congress (ANC) when examining the politics of the ANC during exile. Maintaining power in this way distracts from the larger agenda of the state, which this thesis argues, is to mask the unraveling of the ANC’s hegemony and inability to maintain national unity. In other words, the increasing dissatisfaction of some of the citizenry which has manifested through protest greatly undermines the legitimacy of the government to provide for its people.

- Description: In the current global market, companies are forming partnerships with other organisations with the aim of sustaining their competitive advantage. Most organisations participate in transactions such as mergers, acquisitions and joint ventures in order to maintain their competitive advantage (Sorge, 2002). South Africa forms part of the global market and is not immune towards the stipulated growth strategies. It is believed that South Africa has one of the highest unemployment rate internationally (Human Capital Mangement, 2005). There are various reasons that have contributed towards this perception; factors such as structural changes in the labour market have been highlighted as one of the factors that have contributed to the high unemployment rate (HCM, 2005). It is further said that when mergers and acquisitions occurs, structural changes are bound to occur (Greeve, 2008). Despite the constant merger activities that are occurring in various industries, research has shown that most mergers add no value or reduce shareholders value for the acquiring firm (Kusewitt, 2007). The primary objective of this research is to investigate how organisational behaviour is influenced in an acquired firm.There seems to be high level of uncertainity, trust and communication breakdown amoung employees of Kansai Plascon. This research will investigate whether this perception is related to the acquisition transaction that has occurred. The study will collect its primary data using a set of questionnaires that will be distributed to the employees of Kansai Plascon. The data will be analysed and interpreted.

- Description: Organisations within the South African automotive industry (SAAI) are always seeking innovative ways to remain globally competitive. In order to keep costs as low as possible, existing facilities are often adapted to either cater for a wider variety of products or, alternatively, to produce larger volumes than they were originally designed to produce. In every instance, some form of change needs to take place. When the change management processes are defined within the system, quick wins need to be identified. These quick wins may include the elimination of non-valueadding time that is spent moving paper work between offices or ensuring the correct checks are in place to prevent the process from moving to the next step until all the requirements for the current steps have been completed. Technology has been identified as a suitable support mechanism that would be able to integrate into the complex system that comprises processes to be followed in an order that can be predefined. Every organisation faces its own unique challenges when technology is introduced. These can include a lack of computer literacy and the unwillingness to accept that change can in fact benefit the organisation. Getting the users to take ownership of the new systems through comprehensive training initiatives will be shown to be the most effective manner in which to ensure that the systems are effective and used to their full potential. This treatise will investigate the change management systems currently being used in the SAAI and compare the most important factors against the perceived best practices of the resources that are involved in change management. Organisations that operate at various levels within the SAAI will be researched. A literature review of the best practices in change management systems combined with an investigation into how technology can assist in supporting these best practices will be conducted. The findings will then be summarised and recommendations based on the collected data and information will be formulated and put forward.

- Description: The Research Unit in Bioinformatics at Rhodes University (RUBi), South Africa, offers a Masters of Science in Bioinformatics.Growing demand for bioinformatics qualifications results in applications from across Africa.Courses aim to bridge gaps in the diverse backgrounds of students who range from biologists with no prior computing exposure to computer scientists with no biology background. The programme is evenly split between coursework and research, with diverse modules from a range of departments coveringmathematics, statistics, computer science and biology, with emphasis on application to bioinformatics research. The early focus on research helps bring students up to speed with working as a researcher. We measure success of the programme by the high rate of subsequent entry to PhD study: 10 of 14 students who completed in the years 2011-2013.
