- Description: publisher version , The concept of biocultural diversity, originally used to describe indigenous people and their ways of using and managing natural resources, has more recently been applied within the urban context to understand the variability of interactions between humans and nature. Significant progress has been made internationally in acknowledging the need to preserve and maintain green spaces in urban environments. Current efforts to address the need for greening urban areas in South Africa primarily focus on the establishment and maintenance of botanical gardens and parks as well as various green belts within the urban landscape. South Africa's urban areas are overwhelmingly shaped by the historical segregation of space and stark disparities in wealth. The distribution, quality, and extent of urban green spaces reflect this. Many township dwellers do not have access to these amenities and their interactions with nature are thus usually constrained to access to municipal commonages. This article explores how areas of natural vegetation in municipal commonages on the outskirts of urban centers in South Africa continue to offer places of cultural, spiritual, and restorative importance to Xhosa-speaking township dwellers. A case study from Grahamstown, an urban center in the Eastern Cape with a population of around 80,000, illustrates how ability to access and move through such places contributes to people's well-being, identity formation, and shared heritage. A case is made for adopting a biocultural diversity approach to spatial planning and urban development within the South African context.

Ways of seeing over time: the construction and imagination of ‘historic separation’ in Israeli and Palestinian cultures

- Type: Thesis , Doctoral , PhD
- Identifier: http://hdl.handle.net/10962/474 , vital:19962
- Description: There exists an international consensus that Palestinian and Israeli societies are ceaselessly and essentially acrimonious. This thesis argues that the conceptualisation of ‘historic separation’ in Palestine/Israel is supported and nourished by national narratives that follow classic historicism and a linear trajectory of essentialised culture progressing over time. Given these patterns in historiography and cultural expressions, conceptualisations of the future are argued to be dominated by the ‘overdetermined’ and ‘sacralised’ pasts that arrest the ability to conceive of alternative horizons. These national narratives are analysed borrowing from the theorisation of Edward Said on hegemonic culture, and Ranjit Guha’s Subaltern critique of historicism. Zionism is argued to function as a cultural hegemony that operates in a mercurial, selfsustaining and vibrant manner that has the effect of what this thesis terms ‘centrifugal magnetism’ on discourse in the region. Palestinian national narratives are held to be in tangential relation to Zionism (a classic colonial master-narrative), thus entering into a ‘terrible embrace’ of destructive colonial/postcolonial repetition that tends towards violent conflict and the discrimination of minorities. This thesis then proposes a ‘way out’ of this historiographical pattern that is argued to tangibly inform the cultural fabric of the region. By drawing on the later works of Mahmoud Darwish, Mustaffa Hallaj and Said, it is proposed that there are traces of a notion of self and community that can be described as postnational. This demands a reconstruction of narratives of the past in the region in a pluralistic fashion that is based upon shared exilic identity in flux over what Darwish termed an ‘open historical space’. Crucially, this alternative postnational narrative opens up conceptualisations of the future and is founded upon a renewed disposition to temporality. This thesis thus concludes by proposing that an understanding of temporality as ‘ecstatic’ and essential to being (Martin Heidegger) should be included as a crucial consideration for the end to conflict and the attainment of just and equitable futures.

- Description: The importance of the efficiency of the stock market cannot be underestimated, given that it brings together those who demand and supply development finance. It is against this background that this study focused on analysing the weak form efficiency of the Johannesburg Stock Exchange for the period 2005 to 2016. The study reviewed the theoretical and empirical literatures which have tried to examine the market efficiency of the Johannesburg stock exchange and whether the JSE follows that random walk. Based on the review of literature, several methodologies such as (unit root tests, autocorrelation test) were employed in the study obtaining robust results that the JSE price indices (All Share, Resources and Financials) follow the random walk process. To further confirm the findings in this research, the variance ratio test is conducted under heteroscedasticity and homoscedasticity it also strongly verified that the existence of a random walk process cannot be rejected in the JSE. The empirical results from all the various tests reveal that the null hypothesis of random walk cannot be rejected. These results thus suggest that the JSE is efficient in its weak form. This commends all the measures which have been carried out to ensure that the market is efficient.

- Description: More employees in organisations in the built environment are beginning to suffer from ill health related to work when compared with employees in other industries. There are many reasons for this, such as: unsuitable working conditions, physical demands linked to the occupation and the high proportion of transient unskilled and semi-skilled employees. A study concerning the wellness levels of unskilled and semi-skilled employees therefore contributes to the understanding and improvement of employee health within the industry. The main objective of this study was therefore to identify the wellness levels of employees in the built environment and their perceptions of the extent to which their company provides wellness interventions or strategies. The methodological approach used in this study was within a quantitative paradigm, and a questionnaire was used as a data collection instrument. The findings indicated that the employees engaged in healthy activities and that the organisation encouraged the employees to maintain healthy lifestyles. However, there were areas that required consideration. Specifically, more attention should be given to budgeting for wellness interventions, regular health screenings should take place and more attention to substance abuse is required.

What lies beneath: exploring the deeper purposes of feedback on student writing through considering disciplinary knowledge and knowers

- Description: Feedback plays an integral role in students’ learning and development, as it is often the only personal communication that students have with tutors or lecturers about their own work. Yet, in spite of its integral role in student learning, there is disagreement between how students and tutors or lecturers perceive the pedagogic purpose of feedback. Central to this disagreement is the role that feedback has to play in ensuring that students produce the ‘right’ kinds of knowledge, and become the ‘right’ kinds of knowers within their disciplines. This paper argues that, in order to find common ground between students and tutors or lecturers on what feedback is for, and how to both give and use it effectively, we need to conceptualise disciplinary knowledge and knowers anew. We offer, as a useful starting point, the Specialisation dimension of Legitimation Code Theory as both practical theory and methodological tool for exploring knowledge and knowers in English Studies and Law as two illustrative cases. The paper concludes that this analysis offers lecturers and tutors a fresh understanding of the disciplinary knowledge and knower structures they work within and, relatedly, a clearer view of the work their feedback needs to do within these.

- Description: One of the peculiarities of the literature on academic professional development with regard to teaching is its a-political nature. It pays insufficient attention to issues of equity, and to how privilege, geographical location, class and ethnicity influence the way that staff in higher education learn to teach. This is surprising, or paradoxical, given the strong world-wide concern for widening participation and student success in higher education. The approaches towards professional academic development have been dominated by literature from the global North, which does not take into account conditions in resource-constrained environments. We contend that literature from these Southern environments enrich the international body of literature. Thus there is a need for scholarly writing on learning to teach in higher education, which takes a specifically social, contextual and relational approach and which considers these within resource-rich as well as resource-constrained environments.

The Security Sector, a previously male-dominated sector, is investigated. The environment, the enabling qualities, policy formulation, implementation of gender-sensitive policies, monitoring of the implementation of gender policies and opportunities are explored to investigate their impact on decision-making by women. This research report is based on the hypothesis that, despite the appointment of women in key-decision-making positions, their role in these positions does not make an impact on their overall decision-making, as they are not empowered to perform at their best due to various factors that are analysed in this report. Factors that contribute to or impede impactful decision-making by women in decision-making positions in the Security Sector are investigated in this report. This report acknowledges the efforts made by the SANDF to comply with the required legislation for the empowerment of women in decision-making positions. However the environment, stereotypes and other factors pose a challenge to the impact that women potentially have in decision-making positions. The number of women in decision-making positions poses a challenge to the influence that these appointed women can have in their positions.

- Description: As organisations focus on cultivating extraordinary performance and developing human strength, the need for understanding related constructs has increased. Work engagement, organisational commitment and POS are associated with positive experiences in the workplace. By better understanding these constructs within the agricultural industry, agricultural organisations can focus and develop these constructs in order to increase their sustained competitive advantage. A self-report electronic questionnaire was distributed to employees (N = 126) of a large agricultural organisation whose employees are located throughout South Africa. The measuring instrument measured demographic variables, work engagement, organisational commitment and POS. descriptive and inferential statistics were used to analyse the data. The results indicate that both the work engagement and POS constructs are related to affective, normative and overall organisational commitment. A substantial relationship was also established between work engagement and POS. It was also determined that employees with specialised industry skills are more engaged and committed than their colleagues whose skills are not directly related to agriculture.

- Description: Orientation: Workplace bullying and job engagement influence the degree of employees’ intention to leave their jobs. Research purpose: The overall objective of this research was to establish the relationship between workplace bullying and job engagement and how they impact on the intention to leave. Motivation for the study: Nursing turnover seems to be one of the challenges facing health care sector in South Africa. Workplace bullying and job engagement need to be examined in order to retain best nurses as they influence the degree of employee’s intention to leave. Research approach, design and method: A quantitative research design was used to investigate the degree to which workplace bullying and job engagement predict on the intention to leave. The data was collected using a self-administered questionnaire from a simple random sample of 228 nurses. Pearson correlation and hierarchical multiple regression analyses were employed to test the relationship between workplace bullying, job engagement and the intention to leave. Main findings: Four hypotheses were extracted: There is a significant relationship between workplace bullying and the intention to leave, there is a significant relationship between job engagement and the intention to leave, there is a significant relationship between workplace bullying and job engagement, and there is a significant combined effect of workplace bullying and job engagement on prediction of the intention to leave. The results highlighted a significant combined effect of workplace bullying and job engagement on prediction of the intention to leave. Practical Implications: Based on the findings, the study concludes that workplace bullying and job engagement in nursing are prevalent and have a negative impact on the intention to leave as most of the victims are thinking of quitting once bullying has taken place. Contribution: This study provides a holistic understanding of workplace bullying and job engagement and how they impact on the intention to leave. The findings reflect a significant combined effect of workplace bullying and job engagement on prediction of the intention to leave. It was indicated that workplace bullying and job engagement influenced the extent of employees’ intention to leave.

- Description: Workplace violence is an international problem and has negative consequences for individuals, organizations and communities. For individuals, the effect includes symptoms of fear, stress, irritability, feelings of isolation, insecurity, and low selfesteem. Healthcare organizations incur increased cost due to litigation due to poor quality of care, high staff turnovers and absenteeism, and their brands are negatively affected. Community members, who are the recipients of care, are placed in danger and are indirectly the victims of such workplace violence, which in turn affects their trust in private healthcare organizations or professions to provide the quality health care that they expect and deserve. Workplace violence takes many forms such as incivility, horizontal violence and bullying to name but a few. The perpetrators of such violence are doctors, nurses, patients and relatives. Workplace violence takes place in South Africa however, paucity in research was found by the researcher. The aim of the study was to explore and describe the experiences of professional nurses regarding workplace violence in a private healthcare facility in order to develop guidelines to address workplace violence in such a facility. A qualitative, explorative, contextual and descriptive study was conducted, using the Critical Social Theory as the paradigm. Data were gathered from professional nurses that have experienced workplace violence utilizing narratives. Fourteen narrative interviews were done until data was saturated. The data was transcribed verbatim and Tesch’s method of thematic synthesis was used to analyse the data. The three themes that emerged from the data were: Professional nurses acknowledge the existence of workplace violence where they work, Participants described the effect of workplace violence on themselves, others and the work environment, and Participants discussed their views regarding management of violence in the workplace. A thick description of the data with a literature control was provided. Thereafter inferences were made regarding the main themes of the guidelines and these focussed on: Preventing and addressing workplace violence by Nursing Service Managers; Preventing and addressing workplace violence by Nurse Unit Managers and Empowering professional nurses to address workplace violence. To ensure rigour and trustworthiness of the study, the researcher used Lincoln and Guba’s criteria namely: credibility, dependability, conformability and transferability. To protect the right and dignity of the participants and to safeguard the integrity of the study the researcher complied with the following ethical principles: beneficence, non- maleficence, autonomy, justice, veracity, privacy, and confidentiality. The limitations of this study were that data was collected from only one category of nurses and only one private healthcare facility was used. Recommendations from this study include implementation of the guidelines to establish their effectiveness. The findings of this study can be used to empower professional nurses to deal with workplace violence and to prevent the short and long term effects of workplace violence on the individual, the organization and the community. Nursing education institutions can also incorporate workplace violence into their curriculum to increase the awareness of students regarding this phenomenon.

- Description: Workplace violence is an international problem and has negative consequences for individuals, organizations and communities. For individuals, the effect includes symptoms of fear, stress, irritability, feelings of isolation, insecurity, and low selfesteem. Healthcare organizations incur increased cost due to litigation due to poor quality of care, high staff turnovers and absenteeism, and their brands are negatively affected. Community members, who are the recipients of care, are placed in danger and are indirectly the victims of such workplace violence, which in turn affects their trust in private healthcare organizations or professions to provide the quality health care that they expect and deserve. Workplace violence takes many forms such as incivility, horizontal violence and bullying to name but a few. The perpetrators of such violence are doctors, nurses, patients and relatives. Workplace violence takes place in South Africa however, paucity in research was found by the researcher. The aim of the study was to explore and describe the experiences of professional nurses regarding workplace violence in a private healthcare facility in order to develop guidelines to address workplace violence in such a facility. A qualitative, explorative, contextual and descriptive study was conducted, using the Critical Social Theory as the paradigm. Data were gathered from professional nurses that have experienced workplace violence utilizing narratives. Fourteen narrative interviews were done until data was saturated. The data was transcribed verbatim and Tesch’s method of thematic synthesis was used to analyse the data. The three themes that emerged from the data were: Professional nurses acknowledge the existence of workplace violence where they work, Participants described the effect of workplace violence on themselves, others and the work environment, and Participants discussed their views regarding management of violence in the workplace.

Xenophilia in Muizenberg, South Africa: new potentials for race relations?

- Description: Since the advent of democracy in 1994 race relations in South Africa have not improved substantially. The arrival of transmigrants from other African countries has emphasized a wounded South African psyche, as various xenophobic attitudes and attacks attest. However, a lesser known reality is the expression of xenophilia by South African women. In this article I argue that an intimate relationship between a South African coloured woman and a Congolese black man scripts a different potentiality for multiracial relations in the private and public spaces of urban Cape Town, South Africa.

- Description: Doreen Baingana’s Tropical Fish explores the migratory experiences of the main narrator-focalizer, Christine Mugisha, as she travels from Uganda to the United States of America. Although the analyses of home, exile, and migration by writers like Edward Said and Paul Tiyambe Zeleza tend to be ungendered; Baingana seems to elaborate on these concerns by reflecting on the gendered experience of travel. As Carole Boyce Davies has argued, the act of travelling and migration opens up new spaces and possibilities for black women writers as they come into contact with multiple places and cultures. In their encounters with migration, black women are able to negotiate and re-negotiate their identities. This article focuses on how Tropical Fish, interrogates complex, contradictory, ambiguous and often conflicted questions of home and migration with their concomitant issues of belonging and alienation/ estrangement and how they are intimately tied to the maternal bond.

“A Step Towards Silence”: Samuel Beckett’s The Unnamable and the Problem of Following the Stranger

- Description: In this article, I argue that Samuel Beckett’s The Unnamable evinces the kind of aesthetic ambivalence that Theodor Adorno, in Aesthetic Theory, ascribes to the artwork’s location both in and outside of society. By tracing the metaphors used in the narrator’s depiction of the act of narration, I demonstrate that this novel self-reflexively articulates and meditates on its ambivalent position in society. Thereafter, I relate the work’s suspicion of its medium, and therefore its estrangement from itself, to its critique of community’s norms of recognition, which are embedded in language. Finally, I reflect on the potential effect of the text’s aesthetic ambivalence on the reader.

- Description: Sexuality education, as a component within the Life Orientation (LO) programme in South African schools, is intended to provide young people with knowledge and skills to make informed choices about their sexuality, their own health and that of others. Key to the programme are outcomes relating to power, power relations and gender. In this paper, we apply a critical gender lens to explore the ways in which the teaching of sexuality education engages with larger goals of gender justice. The paper draws from a number of ethnographic studies conducted at 12 South African schools. We focus here on the data collected from focus group discussions with learners, and semi-structured interviews with individual learners, principals and Life Orientation (LO) teachers. The paper highlights the complexities of having gender justice as a central goal of LO sexuality education. Teaching sexuality education is reported to contradict dominant community values and norms. Although some principals and school authorities support gender equity and problematize hegemonic masculinities, learners experience sexuality education as upholding normative gender roles and male power, rather than challenging it. Teachers rely heavily on cautionary messages that put more responsibility for reproductive health on female learners, and use didactic, authoritative pedagogical techniques, which do not acknowledge young people’s experience nor facilitate their sexual agency. These complexities need to be foregrounded and worked with systematically if the goal of gender justice within LO is to be realised.

- Description: Higher education in South Africa is faced with a paramount task to help erode the social and structural inequalities that have been inherited from the Apartheid system (Department of Education 1997; Council on Higher Education 2000:12). The findings from the Soudien Report (2008:116-117) point out that the post-Apartheid higher education system in South Africa is characterised by various forms of discrimination and institutional cultures that marginalise some members of institutions resulting in pervasive feelings of alienation. In the South African higher education field, the concept of a “home” for all has been used by a variety of commentators to depict a vision of what transformed, inclusive higher education institutional cultures might look like. In this thesis, I interpret the experiences of residence life on the part of gay, lesbian and bisexual students on a largely residential campus. I ask how gay, lesbian and bisexual students experience being “at home” in the campus’s residence system. The thesis is based on 18 in-depth qualitative interviews with students who self-identify as gay/lesbian or bisexual who have experienced residence life on the campus for a period longer than six months. A wide literature exists on the concept of “home”. Drawing from many different disciplines including anthropology, history, philosophy, geography, psychology, architecture and sociology, I distil the essential features of “at homeness” as incorporating comfort, privacy, security, acceptance, companionship and community. The research was concerned to inquire into how central the idea of home is to human flourishing and then into how gay, lesbian and bisexual students are routinely denied many of the essential comforts associated with being “at home” that heterosexual students have the privilege of taking for granted.

- Description: Zn octacarboxy phthalocyanine-reduced graphene oxide or graphene oxide conjugates were characterized by absorption spectroscopy, transmission electron microscopy, fluorescence spectroscopy, X-ray diffraction, thermo gravimetric analysis and X-ray photon spectroscopy. The presence of reduced graphene oxide or graphene oxide resulted in the quenching (turn on) of Zn octacarboxy phthalocyanine fluorescence which can be explained by photoinduced electron transfer. Zn octacarboxy phthalocyaninereduced graphene oxide or graphene oxide conjugates “turned on” fluorescence showed a linear response to hydrogen peroxide hence their potential to be used as sensors. The nanoprobe developed showed high selectivity towards hydrogen peroxide in the presence of physiological interferences.

- Description: Using phylogeographic analyses to determine the geographic origins of biological invaders is important for identifying environmental adaptations and genetic composition in their native range as well as biocontrol agents among indigenous herbivores. Eurasian watermilfoil (Myriophyllum spicatum) and its hybrid with northern watermilfoil (M. sibiricum) are found throughout the contiguous United States and southern Canada, forming one of the most economically costly aquatic plant invasions in North America, yet the geographic origin of the invasion remains unknown. The objectives of our study included determining the geographic origin of Eurasian watermilfoil in North America as well as the maternal lineage of the hybrids.
