- Description: The global rollout of Antiretroviral Treatment (ART) has revealed an urgent need to understand the medicines-taking practices of HIV-positive adolescents. In the last decade, the literature on the social determinants of health has broadened the evidence-base on ART adherence. Interdisciplinary studies have expanded conceptions of medicines-taking beyond clinical or health systems frameworks, recognising the importance of socio-structural conditions and of patients’ beliefs and experiences. Participatory research techniques which foreground the perspectives of adolescents provide greater insights still into their adherence. This article explores the use of participatory methods within a broader study on the social determinants of ART adherence among HIV-positive adolescents in South Africa. We describe how participatory methods were incorporated into this study (n = 1,059 in the quantitative baseline). We focus on an exercise, ‘Yummy or crummy?’, that explored the multisensory dimensions of medicines-taking, including their colour, smell, shape, and delivery mechanism. We describe two principal findings: first, adolescents’ preference for greater understanding of the chemical workings of medicines, manifested in their preferences for colour, taste and shape of medicines; and second, the vital relationship between sensory preferences and the social imperatives of discretion and confidentiality regarding HIV-status.

- Description: Background: Pregnancy among adolescent girls in Niger contributes to 34% of all deaths among females ages 15–19, but there is a dearth of research as to the specific contextual causes. In Zinder region, an area that is especially impoverished and where girls are at heightened risk, there is very little information on the main obstacles to improving adolescents’ health and well-being. This qualitative study examines the underlying social, individual and structural factors influencing married girls’ early first birth and participation in alternative opportunities (such as education or economic pursuits) in Niger. Methodology: In July of 2017, researchers conducted in-depth interviews with a non-probability sample of community members in three communes of Zinder Region, Niger. Participants (n = 107) included adolescent girls, husbands of adolescent girls, influential adults, community leaders, health providers, and positive deviants. All interviews were transcribed, coded and analyzed using Dedoose software. Results: Participants recognize the health benefits of delaying first birth, but stigma around infertility and contraceptive use, desire for children, and belief that childbirth is “God’s will” interfere with a girl’s ability to delay. Girls’ social isolation, lack of mobility or autonomy, and inability to envision alternatives to early motherhood compound the issue. Participants favor adolescents’ pursuit of increased economic opportunities or education, but would not support delaying birth to do so. Conclusions: Findings indicate the need for a holistic approach to delaying early birth and stimulating girls’ participation in economic and educational pursuits. Potential interventions include mitigating barriers to reproductive health care; training adolescent girls on viable economic activities; and providing educational opportunities for girls. Effective programs should also include or target immediate members of the girls’ families (husbands, parents, in-laws), influential local leaders and members of the community at large.

- Description: Sexual harassment continues to be a pernicious problem in institutions of higher education globally and findings indicate that women are the main victims. Extant research has focused largely on experiences of sexual harassment on the part of students. Under-researched are the experiences of academics concerning what Benson (1984) terms “contrapower” harassment -- that is, harassment experienced by academics from subordinates such as students. South Africa’s Ministerial Committee on Transformation and Social Cohesion and the Elimination of Discrimination in Public Higher Education Institutions reported that there exists a culture of silencing around the prevalence of sexual harassment in higher education institutions in South Africa (Soudien Report 2008:37). The concept of power has been pointed out as central to understanding sexual harassment (Cleveland and Kerst 1993:49). Utilising three main constructs in Michel Foucault’s conception of power, namely the idea that power is ubiquitous and omnipresent in social relations; that power disciplines – creating docile bodies and the internalisation of self-regulation, and finally the idea that power is productive – power produces knowledge, truth and forms of resistance, I interpret the experiences of contrapower harassment in its sexual and non-sexual forms on the part of female academics at various universities in South Africa. Given that there is a paucity of qualitative research documenting experiences of contrapower harassment on the part of female academics, this thesis draws on 13 in-depth qualitative interviews with female academics at various South African universities who have experienced contrapower harassment from their students and subordinates at any point in their teaching careers. Their narrated experiences provide insight into the phenomenon of contrapower harassment. These insights provide a window into how female academics continue to experience themselves as being out of place in post-apartheid institutions that are expected to be accommodating of all.

- 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: 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.

- Description: This article comments on various translation strategies aiming at equivalence used by translators when reworking Lewis Carroll’s Alice in Wonderland into nine African languages. 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.

The way in which translators created an African voice in the target languages is discussed by analysing their reflective essays and back translations.

- 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.
