- Description: The aim of this study was to develop an understanding of the experiences of caregivers of children with physical disabilities and to explore ways of improving this experience. Although there is a considerable amount of international research on the experiences of caring for children with disabilities, the focus of the methods of enquiry has mainly been on knowledge production and there is limited research conducted using an approach like participatory action research. Secondly, in South Africa, there is still inadequate information regarding the experiences of caregivers who are from low socio-economic backgrounds. It is for these reasons that the current study, which employed PhotoVoice, a participatory research data collection tool, to explore the lived experiences of caregivers of children with physical disabilities from low socio-economic backgrounds was embarked upon. The research methodology comprised two main parts: firstly, a study of relevant literature on the subject matter, in order to gain in-depth understanding of the field; and secondly, qualitative data collection, using PhotoVoice. A sample of six participants between the ages of 22-57 years was selected through purposive and convenience sampling. Cameras were distributed to participants and after processing of images narratives were shared around selected photographs and this was later followed by focused group discussions. This analysis process provided two master themes, which are supported by subordinate themes. The master themes are: 1) The challenges associated with the caregiving experience, 2) The positive side of the caregiving experience. Participants experienced a lack of resources, challenges of mobility, the hopelessness of the situation, loneliness of the experience and the financial burden of caring for a child with physical disabilities as challenges associated with the caregiving role. Whereas the joy brought about by support from family, the health service providers and the Association for People with Physical Disabilities personnel; precious moments shared with the child; and personal growth were associated with the positive side of the caregiving experience. These findings support and expand on the growing knowledge of caring for children with physical disabilities. This research culminated in a sharing of the narratives with stakeholders by caregivers themselves as a way of seeking to influence policy, enhance their well-being and engage in a discussion of exploring ways of improving their experience.

- Description: In the age of digital media, creators are using the versatile nature of information and communication technologies and the ubiquity of the web to publish and distribute texts, circumventing traditional gatekeepers such as publishing institutions. In Africa, where web access and digitisation are relatively new, storytellers are eagerly exploring new mediums and the possibilities that they provide for African narratives and African representation. This thesis looks at the digital platforms of the African Storybook Reader, the FunDza Literacy Project, and Long Story SHORT, as well as Dudu Busani-Dube’s novel Hlomu the Wife, which first gained popularity on a blog platform. It examines three different web series, An African City, The Foxy Five, and Tuko Macho, as well as a transmedia documentary, Love Radio. The texts are grouped into literatures disseminated from digital platforms, localised narratives that explore the urban African woman, and narratives that make use of participatory culture. These are texts that make use of digital tools and platforms to create and disseminate African stories, making diverse and indigenous narratives more easily accessible to both local and global audiences. This thesis argues that digitisation and the global nature of the internet have created opportunities for Africans to become producers and exporters of indigenous information and representation, rather than passive consumers of imported knowledge, or subjects of external characterisation.

- Description: This study explored the phenomenon of juvenile delinquency in grandparent headed families in Hill Crest, Alice township, Eastern Cape. The study endeavoured to achieve the following specific objectives: (I) to determine the factors associated with juvenile delinquency in grandparent headed family environments; (ii) to ascertain the experiences encountered by grandparent headed families due to juvenile delinquency. (iii) to establish the support system provided by the relevant stakeholders (probation officers, police, school officials and grandparents) to address juvenile delinquency in grandparent headed families. The study was premised on theoretical lenses of the social bond theory, social learning theory and general strain theory. Methodologically, the study used the qualitative approach guided by the exploratory-descriptive research design and phenomenology was adopted as the specific research design. The data was collected through in-depth one-on-one interviews, focus group discussions and key informant method. Also, the study used non-probability method sample selection, specifically purposive sampling technique was used. Using this technique, nineteen (19) participants were selected comprised of five (5) grandchildren, eighty (8) grandparents, two (2) probation officers, two (2) police officers, one (1) community committee member and one (1) school official. Data were analysed through thematic analysis. The study revealed the following findings: the grandparent household have unique factors that are contributing to juvenile delinquency these include old age, overprotection, backgrounds of grandchildren to mention but just a few; delinquency by grandchildren has spill over effects that are adversely affecting the lives of grandparents for instance health deterioration, victimisation and loss of property; ii grandparents have their own means of addressing juvenile delinquency such as corporal punishment, emotional attachment and religion; the department of social development has programmes in place to assist grandparents, however, they are facing some challenges in effectively execute them; relevant stakeholders such as police and schools shown reluctance in addressing juvenile delinquency in grandparent headed families. Based on the evidence gathered, this study made the following recommendations: development of programmes to assist grandparent headed households on parenting; mentoring programmes for vulnerable children; the appointment and active involvement of youth workers; social development need to need to regard probation as a specialised area and policies should be developed protecting old aged persons from taking full custody of children. The study concluded that grandparent headed households are contributing to juvenile delinquency and old age was determined to be the central key factor giving birth to this quagmire.

- Description: IsiXhosa literary critics have not yet interrogated literature that was produced during and after the tenure of Thabo Mvuyelwa Mbeki as deputy president and president of the Republic of South Africa in order to study the impact of his African Renaissance doctrine. This article analyses poetry that was produced from 2005 to 2011. The content of the isiXhosa written poetry is profoundly influenced by the context of former President Mbeki's African Renaissance philosophy, its implementation structures and philosophy of self-confidence and self-reliance. The selected poems analysed and interpreted in this article suggest that Mbeki's legacy of the African Renaissance empowered poets to develop a narrative that advances the building of a regenerated South African nation and the African continent.

- Description: We report phototransferred thermoluminescence (PTTL) and thermally-assisted optically stimulated luminescence (TA-OSL) of α-Al2O3:C,Mg annealed at 1200 °C. PTTL is TL measured from an irradiated phosphor after its exposure to light. The other theme of this study, TA-OSL is the additional amount of luminescence optically stimulated from a sample over and above the amount that would be measured at room temperature. A sample irradiated to 10 Gy and preheated to 230 °C at 1 °C/s followed by illumination by 470 nm blue light produced four PTTL peaks at 53, 80, 102 and 173 °C. The PTTL peaks occur at the same positions as the corresponding conventional TL peaks. Their kinetic parameters are also similar. The intensity of the PTTL peaks increased with duration of illumination to a maximum within 200 s for doses between 1 Gy and 10 Gy. The dose response of each of the PTTL peaks at 80, 102 and 173 °C is linear within 1–15 Gy. The rate of fading is low and the peaks are reproducible. When the irradiated sample is optically stimulated at temperatures between 30 °C and 300 °C, after preheating to 500 °C, the intensity of its TA-OSL goes through a peak with temperature at 200 °C. Using the rising edge of the plot, activation energy of thermal assistance for a deep electron trap was estimated as (0.21 ± 0.02) eV. The TA-OSL dose response is sublinear from 10–250 Gy and saturates thereafter. The PTTL and TA-OSL analyses signify that the concentration of deep traps in α-Al2O3:C,Mg increased after annealing at 1200 °C. As a result, the sample produced better PTTL and TA-OSL response than when annealed at lower temperature.

- Description: Using a Karl G. Jansky Very Large Array (VLA) L-band (1-2 GHz) survey covering ∼100 deg2 of the Stripe 82 field, we have obtained a catalogue of 2716 radio AGNs. For these AGNs, we investigate the impact of galaxy density on 1.4 GHz radio luminosity (L1.4). We determine their close environment densities using the surface density parameter, ΣN, for N = 2 and N = 5, which we bin by redshift to obtain a pseudo-3D galaxy density measure. Matching the radio AGNs to sources without radio detections in terms of redshift, K-band magnitude and (g − K) colour index, we obtain samples of control galaxies and determine whether radio AGN environments differ from this general population.

The back translations provided by the translators form the basis for the discussion [Lindseth, Jon, ed. 2015. Alice in a World of Wonderlands. Volume 1: Essays. Delaware: Oak Knoll Press]. This article provides examples and discussion of how African language translators deviated from the original text and it analyses the possible reasons for doing so, both linguistic and socio-cultural. The way in which translators created an African voice in the target languages is discussed by analysing their reflective essays and back translations.

- Description: Background: Despite the array of studies on infant feeding practices of HIV-infected women, gaps still exist in the understanding of the underlying reasons for their infant feeding choices. Potential for behavioural change exists, especially in the light of the 2016 updated World Health Organization guideline on HIV and infant feeding. The aim of this paper is to determine the rate of adoption of exclusive breastfeeding in this cohort, examine the determinants of infant feeding choices of HIV-infected women and assess the underlying reasons for these choices. Methods: This was a mixed methods study conducted between September 2015 and May 2016. It analyses the quantitative and qualitative data of 1662 peripartum women enrolled in the East London Prospective Cohort Study across three large maternity services in the Eastern Cape. Women with HIV reported their preferred choices of infant feeding. In addition, participants explained the underlying reasons for their choices. Descriptive and inferential statistics summarised the quantitative data, while thematic content analysis was performed on qualitative data. Results: Of the 1662 women with complete responses, 80.3% opted to exclusively breastfeed their babies. In the adjusted model, up to grade 12 education level (AOR: 1.81; 95% CI: 1.14, 2.86), rural/peri-urban residence (AOR:1.44; 95% CI: 1.05, 1.96), alcohol use (AOR: 1.65; 95% CI: 1.25, 2.18), negative or unknown HIV status at booking (AOR:1.85; 95% CI:1.27, 2.70), currently married (AOR:1.43; 95% CI:1.01, 2.02) and WHO Clinical Stage 2–4 (AOR:1.77; 95% CI: 1.15, 2.72) were significantly associated with the decision to exclusively breastfeed. Health care providers’ recommendations, perceived benefits of breastfeeding, unaffordability of formula feeding, and coercion were the underlying reasons for wanting to breastfeed; while work/school-related demands, breast-related issues, and fear of infecting the baby influenced their decision to formula feed. Conclusion: The majority of HIV-infected women chose to breastfeed their babies in the Eastern Cape. Following up on these women to ensure they breastfeed exclusively, while also addressing their possible concerns, could be an important policy intervention. Future studies should focus on how early infant feeding decisions change over time, as well as the health outcomes for mother and child.

Following up on these women to ensure they breastfeed exclusively, while also addressing their possible concerns, could be an important policy intervention. Future studies should focus on how early infant feeding decisions change over time, as well as the health outcomes for mother and child.

- Description: The biosynthesis of silver nanoparticles (Ag-NPs) using the hydrosol extract of the dry stem bark of Acacia mearnsii as reducing and capping agents, and their antinociceptive properties are hereby reported. By varying the temperature and reaction time, the temporal evolution of the optical and morphological properties of the as-synthesized material was investigated. The NPs were characterized by UV–visible absorption spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDS) and x-ray diffractometry (XRD) The optical analyses show that the position of the maximum surface plasmon resonance (SPR) peak is red-shifted as the reaction temperature decreased. The TEM micrographs show that the as-synthesized Ag-NPs are spherical while the X-ray diffraction shows that the material is highly crystalline with face-centered cubic structures. The anti-inflammatory efficacy, analyzed by the formalin model, indicates that the as-synthesized Ag-NPs are very effective, with an inhibition rate of about 76%.

- Description: The ecosystem services (ES) concept can frame the value of protected areas (PAs) to society and identify management actions that bridge biodiversity conservation and human benefits. In this special issue on ES flows to and from southern African PAs we consider two themes: (1) water as a biophysical and social-ecological connector; and (2) cross-scale interactions and connections as influences on cultural ecosystem service (CES) provision. Freshwater flows have supporting, regulating, and cultural elements, leading to complexities in governance as well as place attachment, intellectual, and recreational services. Scale dependence in CES creates trade-offs that challenge the usefulness of the ES framework for PA management. Ecosystem service production can potentially create political support for PAs and helps to build connections and feedbacks that increase PA resilience. Papers in the feature highlight a need to understand trade-offs in optimising for biodiversity vs. particular bundles of ES; impacts of investment in built infrastructure on ES use; how managers facilitate ES; scale and heterogeneity as influences; the role of adaptive monitoring of PAs as social–ecological systems; and services and benefits from PAs that are not well-articulated in ES classifications. PA research can thus add nuance, depth and substance to broader thinking around CES.

The Fishes of Zimbabwe and their Biology

- Description: The first comprehensive book on the fishes of Zimbabwe appeared in 1961 and was written by Rex Jubb. He followed it with a major treatise on the fishes of southern Africa published in 1967. These books were published at a time when interest in fishes – partly stimulated by the creation of Lake Kariba –was growing, and they were welcomed by anglers and scientists alike. Zimbabwean ichthyology progressed rapidly during the years following their publication and knowledge about our fishes grew steadily. New insights and understanding of their systematics led to numerous taxonomic revisions, bringing with them inevitable changes to their scientific names. At the same time increased collecting meant that new species were being added to the Zimbabwean list. By the early 1970s Jubb’s books had become outdated and there was a clear need for a new volume on the fishes of this country. The National Museums and Monuments met this need by publishing Graham Bell-Cross’ The Fishes of Rhodesia in 1976. This book was available at a remarkably low price and such was its popularity that it was soon out of print. It rapidly became outdated as well and was revised by John Minshull as the Fishes of Zimbabwe, published in 1988. This version had a number of new features such as the inclusion of exotic species and species discovered in the country since 1976, as well as name changes brought about by new developments in taxonomy. It, too, was available at a very low price and has proved to be very popular; the demand was so great that it was reprinted without alteration in the 1990s. By this time, however, it had also become outdated and there was a need for yet another revision, or for a completely new type of book. I have chosen the latter option in preparing this book, since there seemed little point in attempting to revise the earlier ones within their original format. I felt that it would not be desirable to produce another field guide type of book that would have to compete with Paul Skelton’s superb volume, A Complete Guide to the Freshwater Fishes of Southern Africa, first published in 1993, with a second edition eight years later. Instead, I decided that I should try to summarise the existing data about fishes in Zimbabwe. My dealings with students and inexperienced fish biologists has made it clear that many of them do not know what work has been done, or not done, on Zimbabwe’s fishes and they are not familiar with the literature. Much of it is, in any case, to be found in obscure publications that are not readily available in Zimbabwean libraries, which have declined in recent years and no longer subscribe to major international journals or even to local ones. This makes it very difficult to keep up with information or to track it down. I am aware, of course, that such a book will never be complete and may already be outdated at the time of its publication, but I hope that it will supply the basic background information for anyone interested in Zimbabwean fishes and provide a platform from which further studies can be launched. Wherever possible, I have used only data from Zimbabwe, although there may be an extensive literature from other countries for widespread or economically important species, such as Clarias gariepinus or Oreochromis mossambicus. This was a conscious decision because I wanted to summarise what is known about the fish in this country, so that other workers can assess what still needs to be done. Nevertheless, I have used some data from outside Zimbabwe, especially for fish from the upper Zambezi because of its relevance to our situation. As far as possible I have tried to use only published works as references, with the exception of university theses and some institutional reports, since most unpublished work is generally difficult to locate and ephemeral. The scientific names of fishes often change as systematic knowledge advances and the reader will note that there have been many changes since Bell-Cross & Minshull (1988) was published. Common names are a problem because of local variations and anglers in particular have various names (or nicknames) for popular angling species; I have used the standard names with these other names included in brackets where necessary.
