  • Description: This treatise aims to uncover possible reasons as to why composers rework their compositions. In attempting to answer questions regarding musical and extra-musical (referential) criteria, surrounding conditions and the role performers play in acting as conduits of the aforementioned, the study focuses on three versions of Rachmaninoff’s second Piano Sonata, opus 36. The first of these was composed in 1913, the second constitutes the composer’s revision of this work in 1931, and the third, a subsequent amalgamation of both previously mentioned versions by pianist Horowitz in 1943. The research is grounded in the theoretical ideas of organicist musical structuralism and thematic/motivic transformation (Reti), musical hermeneutics and phenomenology, musical forces (Larsen) and authenticity in musical performance (Taruskin). In addition this study explores methods of critical reading that may be used to disclose the conflicting yet complementary demands of “conciseness” and “drama” contained within the parameters of the three aforementioned versions of Rachmaninoff’s Piano Sonata Op. 36. An introductory chapter is followed by one in which a historical context provides the intertextual matrix against which the musical personae of Rachmaninoff and Horowitz, as well as the three versions of Rachmaninoff’s Piano Sonata Op. 36, may be understood. The chapter thereafter provides a concise overview of the history of musical analysis and the Tendenzwende which signified the change from a purely positivistic analytical approach to a post-modernist perspective on musical critique, against which background a motivation is provided for the analytical approaches applied in this treatise. Chapters 4 and 5 present detailed readings of the sonata from the perspective of “conciseness” and “drama” respectively. In conclusion, the final chapter reflects on findings made and conclusion drawn, with particular reference to the authenticity debate in current musicological discourse.

  • Description: The South African Constitution provides that a child’s best interests are of paramount importance in every matter concerning the child. This principle emanates from the United Nations Declaration on the Rights of the Child (UNCRC) and the African Charter on the Rights and Welfare of the Child (ACRWC). Accordingly the State and its various departments have adopted and are enforcing legislation and policies in defence of the child’s best interest. The principle of the best interest of the child is seldom observed in most of our schools. Incidents of child abuse are on the increase, especially by educators. This unfortunate situation prevails against the backdrop of legislation which condemns these atrocities. Section 17 of the Employment of Educators Act1 provides that educators must be discharged if they are found guilty of, inter alia, sexual abuse, intimate relationship with a learner and assault with grievous bodily harm. These measures have been taken to combat the vicious cycle of child abuse in schools and to advance children’s-rights agenda and the universal principle of the child’s best interests. For the department to successfully prosecute educator cases against child abuse, the testimony of a child witness is crucial. However, it is shocking to discover that the interests of the child witness are not always served in these disciplinary hearings. Officials are prone to be biased towards their fellow professionals at the expense of the interest of the child witness. This situation normally arises probably as a result of a lack of professional capacity because most of these officials tasked with disciplining educators have a teaching, human-resource or legal qualification. Others may have been recruited from the ranks of the trade-union movement without any formal qualification. Secondly, they may be specialists in the field of labour law which is essentially concerned with the regulating the employer and employee relationship. Thirdly, the disciplinary code and procedures that are used during educator-disciplinary processes are premised on the principles and values of the Labour 1 Act 76 of 1998. Relations Act Code of Good Practice: Dismissal2 and Schedule 2 of the Employment of Educators Act3 which addresses the interest of the child witness to a very limited extend. Finally, the policies regulating workplace discipline are generally biased towards employee rights as espoused in the Labour Relations Act4 and CCMA guidelines on misconduct arbitrations. This study has identified a number of challenges confronting the child witness and also areas of capacity improvement on the side of officials officiating over the disciplinary cases of educators. These challenges form the basis for a comprehensive and consolidated list of aspects in which officials need to be trained to effectively promote and defend the interest of the child witness in a professional manner. The role of the departmental representative in becoming the champions of the democratic Constitution and the vanguard of the child’s best interest cannot be over-emphasised. The question of how best to serve the best interest of the child witness has been addressed. The child witness can be a credible witness provided officials win over his or her confidence to speak out against abuse. The 16 days of activism against women and children abuse has to resonate consciously with departmental officials.

  • Description: Poverty in South Africa is vast. This is an open secret as it manifests itself in so many ways. It is widely known that South Africans are faced with one of poverty indicators, such as unemployment; hence our government is committed to fight poverty in various ways like, poverty alleviation, poverty eradication and poverty reduction programmes. This study looked at poverty of targeted people after Zamokuhle Ngcweleni was implemented. The researcher looked at the project’s contribution on poverty under sustainable livelihood approach with guidance of OECD(1991) criteria of judging the project these being; relevance, effectiveness and sustainability South Africa is committed in this regard with policies and strategies directed to fight poverty, Altman, Hart and Jacobs (2009). In the Constitution of South Africa (Act 1996) section 27 (1) (b)-(c) of this country, poverty is set to be fought, that people must have access to food sustainably through food security strategy. Government, through its departments commits to deliver to mostly affected people, services that deal with poverty reduction. The Department of Social Development is one of the vehicles to get these services to poverty stricken people blamed to history, politics and social ills. It is upon this background the study is done. The community of Ngcweleni with the assistance of the Department of Social Development and Special Programme has assumed this project, the Zamokuhle Ngcweleni with two activities, household gardens and egg production. 30 beneficiaries would sell for income and feed from the produce .This project started in 2010/11 financial year by the sub section, sustainable livelihood in the DOSD, based from the socio economic conditions of Ngcweleni where poverty is one the characteristic. The Zamokuhle Ngcweleni project was randomly chosen by the researcher for this study. The research was based on the aims and objective of the study. The study took place in a natural setting and was descriptive. Interviews, focus groups, documents and household survey were used by the researcher as data collection tools. The study was qualitative. Data was analysed using themes and interpreted thereafter. Participants were the beneficiaries of the Zamokuhle Ngcweleni project and officials of the department. Tables and graphs were used for biographical information to show age, gender, educational and marital status of the beneficiaries; for officials it showed qualification, designation and gender. The researcher gathered that the project has contributed positively to the poverty of the beneficiaries because of its relevance and effectiveness. It made beneficiaries food secure and the impact showed poverty is reduced. The project showed unsustainability and the researcher recommends the needs to investigate this further.

  • Description: In this study, we report on the covalent linking of carboxylic acid functionalized silica nanoparticles with zinc phthalocyanine mono-substituted non-peripherally and peripherally with either a 4-amino phenoxy (1, peripheral and 2, non-peripheral) or an amino group (3 peripheral). The grafting is achieved via the formation of an amide bond between the carboxylic acid of the silica nanoparticles and the amino group of the phthalocyanine complexes. The hybrid nanoparticles retained the amorphous nature of silica nanoparticles after conjugation. A slight decrease in fluorescence and a general improvement in triplet quantum yields compared to free Pcs were observed. Triplet lifetimes for 2-SiNPs and 3-SiNPs also improved when compared to the free phthalocyanine. The changes in singlet oxygen quantum yields upon conjugation were minimal.

Conscientious objection to performing same-sex marriage in South Africa

  • Authors: Kruuse, Helen
  • Date: 2014

  • Identifier: http://hdl.handle.net/10962/129186 , vital:36228 , https://doi.org/10.1093/lawfam/ebu001
  • Description: This article considers whether public servants should be exempt from South Africa’s equality provisions and anti-discrimination legislation in solemnizing same-sex marriages. In order to deal with this question, the article analyses the treatment of freedom of conscience and conscientious objection by comparing the solemnization of same-sex marriage by public servants, with another public service: that of terminations of pregnancy. While each situation will inevitably turn on the particular circumstances of the case, I argue that there should be a content-neutral guiding principle (as well as consistency) in dealing with these situations. The issue in each situation is narrowed to whether a civil servant’s personal convictions can override the state’s secular obligations in providing a service, and whether there is room for a qualified right to conscientious objection. By analysing the matter in this way, it is clear that the unqualified statutory exemption clause in South Africa’s Civil Union Act is constitutionally objectionable.

  • Description: There is a global increase in research on the benefits of animals and the value of incorporating them into interventional practices. This is referred to as animal-assisted interventions. Due to the novelty of this type of intervention and the accompanying complexity of variables, a need exists to explore the various aspects within these interventions. Looking specifically at animal-assisted interventions within the mental health field, this study focuses on the psycho-therapeutic value of companion animals, such as dogs and cats. The primary aim of this study was to identify the mechanisms through which an animal-assisted intervention exerts its influence. A secondary aim was to indentify salient methodological aspects within the included studies. A systematic review of existing literature was undertaken to explore these factors. Each study was appraised against specific inclusion and exclusion criteria and themes were extracted. The data was synthesised, integrated and discussed in relation to previously conducted studies in relevant fields. Six themes emerged from the systematic review. These included enhanced comfort, the living nature of animals, physical contact, adjunctive nature, an affinity for animals, as well as methodological considerations. Based on these emergent themes conclusions were drawn as to the psycho-therapeutic influences of companion animals. This may serve as informative knowledge regarding animal-assisted interventions for practitioners seeking additional methods to reach treatment goals. Information is also provided for researchers interested in the field, particularly methodological considerations, before embarking on a study of animal-assisted intervention efficacy.

Reviewing the definition of the natural resource curse and analysing its occurence post-1990

  • Description: That countries with high natural resource abundance should experience slower economic growth than those with low resource abundance seems contrary to what would be expected, considering the developmental head-start such resources afford. Yet Sachs and Warner (1997) found that economies with a high share of natural resource exports in national income in 1970 tended to experience slower economic growth in the two decades that followed. This finding, that natural resources are a “curse” rather than a blessing, has become generally accepted. This thesis sought to test whether the conclusion drawn from their data – that higher natural resource abundance leads to slower economic growth – is still correct. It sought to test their findings first by correcting for their use of resource intensity (natural resources share of exports) as a proxy for abundance. Using measures of resource abundance for 1995 as a proxy for abundance in previous decades, it was found that higher resource abundance was not associated with lower economic growth in the 1970s and 1980s. This finding is contrary to that of Sachs and Warner (1997, 2001). Secondly, this thesis tested whether the natural resource curse effect was still present for the period 1995–2010. This was done by observing the effect of both resource abundance and resource intensity on economic growth during 1995–2010. In both cases no resource curse effect was found, for this more recent period. The resource curse had disappeared regardless of whether one uses Sachs and Warner’s (1997, 2001) measure of resource intensity or a measure of resource abundance. Natural resources should therefore no longer be considered a “curse”. In explaining the difference for the impact of resource intensity between the 1970-90 period measured by Sachs and Warner (1997, 2001) and the more recent period 1995-2010 it was found that the Dutch Disease effect has decreased significantly since the 1970s and 1980s. This could partly explain why the resource curse has disappeared when measured in terms of resource intensity. Thus it was concluded that the natural resource curse existed in the period 1970-90 only when measured in terms of resource intensity but not when measured relative to resource abundance. The negative effects of natural resources on economic growth have disappeared in terms of both resource intensity and resource abundance in the more recent time period.

  • Description: This study investigated the potential impacts of several anthropogenic stressors on the movement and survival of African penguins in Algoa Bay, taking into account prey availability and environmental conditions (sea surface temperature and chlorophyll productivity). The primary drive for the study was based on the seismic exploration, which took place in the habitat of the endangered African penguin. The research was also carried out to understand how pelagic fishing and prey availability influence the broader behavioural and mortality aspects of penguins. To achieve this goal, I used monthly beach surveys to assess seabird mortality, admissions of penguins in rehabilitation centres and the monitoring of breeding penguins’ movement at sea through individual GPS tracking. In addition, prey distribution and abundance were monitored with acoustic surveys to assess potential changes in relation anthropogenic stressors. Breeding African penguins did not react dramatically to seismic activities, except on St Croix Island where they changed their foraging direction during the seismic period. There was no evidence of a siginficant increase in African penguin carcasses encountered or strandings along the beaches during the period of seismic activity. However, a sharp increase in encounter rate was recorded soon after seismic operations, which may potentially indicate a delay between the effect of seismic activities on penguin mortality and the encounter of the related carcasses after the operation. However, the impact of seismic surveys on penguins may be long-term rather than short term, and additional studies would be needed to reveal long-term effects of seismic activities, if any. Foraging effort of breeding African penguins increased substantially in the presence of commercial fishing activities within close proximity to the colonies. To a greater extent, at-sea movement patterns and counts of beach cast carcasses were largely influenced by prey availability. Penguins spent more time at sea, traveled longer and covered a larger foraging area during periods of relatvely low pelagic fish abundance. There was also a sharp increase in African penguin mortality during periods of low prey availability in the Bay. However, environmental conditions showed some influence over these interactions. Foraging effort of breeding African penguins increased substantially in the presence of commercial fishing activities within close proximity to the colonies. To a greater extent, at-sea movement patterns and counts of beach cast carcasses were largely influenced by prey availability. Penguins spent more time at sea, traveled longer and covered a larger foraging area during periods of relatvely low pelagic fish abundance. There was also a sharp increase in African penguin mortality during periods of low prey availability in the Bay. However, environmental conditions showed some influence over these interactions. For example a red tide event during in period of low prey availability, made it difficult to understand impacts of prey on penguins difficult. Both anthropogenic stressors and environmental conditions influenced African penguins’ behaviour and survival. Due to the worrying trend of African penguins in South Africa for the past few years, all conservation management efforts to increase penguin numbers and limit their mortality are necessary. This study highlights the negative impact of industrial fishing on this Endangered species and the rapid increase in mortality of penguins during times of low prey availability. A network of Marine Protected Areas would certainly increase food availability to African penguins by limiting competition with fisheries, and contribute to increasing the population numbers.

  • Description: The focus of this study was on the experiences of a small sample of local women who are HIVpositive and are living in poverty. The researcher was interested in exploring the psychological and social experiences of these women using Interpretive Phenomenological Analysis. This research aimed at giving these women a voice to express their first-hand, personal accounts of living with HIV in poverty. Data was analysed for meaningful units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Six themes within the participants' experiences of living with HIV were determined, namely: (I) experiences of diagnosis, (2) disclosure experiences, (3) stigma, (4) ARV experiences, (5) experiences of social support and (6) poverty. This research found that after an HIV-positive diagnosis, most women experience a variety of emotional reactions. These reactions however seem to change overtime into positive acceptance of the HIV diagnosis. Most of the women in this study preferred to use partial disclosure than to fully disclose their HJV-positive status openly to families, friends and to their community. Reasons for not using full disclosure included fear of discrimination and stigma, which included a fear of being rejected or being blamed for their status and a fear of losing relationships. It was also evident from the findings that most of the women had experienced stigma directly and therefore partial disclosure was used as a coping mechanism to protect the self from further harm. It was also revealed that stigma not only has a negative impact on disclosure but also on social support and ARV experiences. Because ofHIV-related stigma, lack of social support was a struggle that almost all the women in this study had experienced. Lack of understandings about their medication also had a negative impact of the ARV experiences. Stigmas along with poverty are the major struggles that HIV -positive women have to deal with in their day to day living. The findings of this study reveal a need for further research in this experiential area as well as campaigns and education around issues such as stigma, medication, and emotional difficulties associated with HIV.

  • Description: Due to the high heterogeneity of breast cancers, numerous recent patents describe improved methods of detection and classification which promise better patient prognosis and treatment. In particular, there has been a shift towards more effective genetic screening to identify specific mutations associated with breast tumours, which may lead to “personalised medicine” with improved outcomes. Two challenging areas of breast cancer research involve the development of treatments for the highly aggressive triple negative breast cancer subtype as well as the chemotherapy-resistant cancer stem cell subpopulation. In addition, despite numerous recent advances in breast cancer treatment in woman, male breast cancer remains poorly understood and there are limited therapies available which are developed specifically for men. This review serves to report on important developments in the treatment of breast malignancies patented in the past two years as well as to highlight the current gaps in the field of breast cancer therapeutics and areas which require further study.

To achieve this goal, the following act ions were ta ken: Aliterature study was conducted to identify the best strategies that South African companies could use to manage knowledge workers for optimal benefit; Following the literature review interviews were concluded with key people in the human resource and recruitment industry to determine how a knowledge worker was defined in their organisations as well as to probe what management and human resources strategies were used to manage knowledge workers to their full potential; The interviews, in addition to the literature study, also served as a basis for a survey questionnaire, which was used to probe the views of knowledge workers to determine tools and strategies managers use to manage them. The empirical results from the study showed some concurrence with best strategies suggested from the theoret ical study. In essence, the study revealed that knowledge was well managed in the organisations where the study was conducted and that the knowledge workers were motivated and productive. However, it appeared that there was uncer tainty around the remuneration, rewards and recognition of these employees, which could ultimately reflect in less promising levels of commitment and lower levels of retention. The main findings were that: knowledge workers should be recognised for their good performance by providing financial incentives; knowledge workers should be provided with opportunities to continuously develop their competencies but be allowed to craft their own developmental experiences; knowledge workers should be empowered by delegat ing tasks to them that carry decision making responsibility and af fectinnovation; and Managers and knowledge workers should cont inuously have performance and organisational development discussions.

  • Description: Developing countries face challenges in the development of infrastructure and population growth. These lead to “side-effects" such as uncontrolled urbanization and the fact that basic services such as water and sanitation are lagging behind the actual needs on the ground. Historical challenges, lack of skilled staff and often lack of sustained funding are some of the reasons for the status quo. Extent of water and sanitation coverage often forces national and local governments to install the minimum-standard solutions, e.g. the ventilated improved pit latrines. This improves the public health status in the short-term, but causes problem in the long run due to the lack of regular maintenance such as through lack emptying of pits. Sometimes, construction of these facilities is of inferior standard. Pits are often built without lining or zero consideration is given to the local conditions in terms of soil properties, water table and the number of toilet users.

  • Description: The main research question guiding this study is: “What strategies can be established to enhance parental involvement in primary schools in disadvantaged communities in the Northern Areas of Port Elizabeth”? To answer this question, this study examines parents’ and teachers’ practices concerning parental involvement in the Northern Areas of Nelson Mandela Metropolitan. Parents and teachers were purposely selected from participating schools. In this qualitative study, the researcher proposed strategies to enhance parental involvement at primary schools. Qualitative research methods, associated with phenomenological inquiry were employed to explore the life-world of the participants who have had personal experience with the phenomenon of parental involvement. Data was collected through semi-structured interviews with parents and teachers. This allowed the researcher to gather in-depth information about opinions, beliefs, practices and attitudes concerning the involvement of parents in their children’s education. Bronfenbrenner’s ecosystemic theory served as the theorectical framework of this investigation. Since this study is about parental involvement in primary schools educational policies like inclusive education as well as different models of parental involvement were investigated in the literature study. The results of the study indicated several barriers to the enhancement of parental involvement for instance communication barriers between parents and teachers. The researcher established four strategies for the enhancement of parental involvement and recommended that these strategies should be employed by schools and other stakeholders. She also made further recommendations for parents, teachers, school principals, Department of Basic Education and professionals in the community.

  • Description: Monitoring unused IP address space by using network telescopes provides a favourable environment for researchers to study and detect malware, worms, denial of service and scanning activities. Research in the field of network telescopes has progressed over the past decade resulting in the development of an increased number of overlapping datasets. Rhodes University's network of telescope sensors has continued to grow with additional network telescopes being brought online. At the time of writing, Rhodes University has a distributed network of five relatively small /24 network telescopes. With five network telescope sensors, this research focuses on comparative and correlation analysis of traffic activity across the network of telescope sensors. To aid summarisation and visualisation techniques, time series' representing time-based traffic activity, are constructed. By employing an iterative experimental process of captured traffic, two natural categories of the five network telescopes are presented. Using the cross- and auto-correlation methods of time series analysis, moderate correlation of traffic activity was achieved between telescope sensors in each category. Weak to moderate correlation was calculated when comparing category A and category B network telescopes' datasets. Results were significantly improved by studying TCP traffic separately. Moderate to strong correlation coefficients in each category were calculated when using TCP traffic only. UDP traffic analysis showed weaker correlation between sensors, however the uniformity of ICMP traffic showed correlation of traffic activity across all sensors. The results confirmed the visual observation of traffic relativity in telescope sensors within the same category and quantitatively analysed the correlation of network telescopes' traffic activity.

  • Description: From Foreword by Dr Sizwe Mabizela: In the year under review, individual academics continued to receive widespread recognition for their work. Particularly noteworthy were the accolades that Distinguished Professor Tebello Nyokong continued to attract. In 2014 she was chosen as one of South Africa’s 21 Icons. Professor Nyokong was also appointed by United Nations Secretary- General Ban Ki-Moon to the High-Level Panel on Technology Bank For Least Developed Countries. Money cannot buy the kind of positive profile that Professor Nyokong brings to Rhodes. Professor Janice Limson was awarded the DST/NRF SARChI Chair in Science Communication. This brought to 11 the number of SARChI Chairs awarded to Rhodes University. Professor Heila Lotz-Sisitka was appointed as the inaugural Director of the new Postgraduate Studies Centre, to lead and manage the provision of additional support for enhancing the quality, quantity, and equity of our Postgraduate population. , A publication of the Rhodes University Research Office, compiled and edited by Jaine Roberts, Tarryn Gillitt, Thumeka Mantolo, Patricia Jacob and Jill Macgregor.
