Border crossings in the African travel narratives of Ibn Battuta, Richard Burton and Paul Theroux
(Taylor & Francis, 2012)This article compares the representation of African borders in the 14th-century travelogue of Ibn Battuta, the 19th-century travel narrative of Richard Burton and the 21st-century travel writing of Paul Theroux. It ... -
Borehole dilution experiment in a Karoo aquifer in Bloemfontein
(Water Research Commission, 1997)This paper shows that a borehole dilution experiment using common salt is a useful technique for better understanding of some hydrogeological features of a fractured aquifer. A sense of such tracer experiments was performed ... -
Boundaries of benefit sharing: interpretation and application of substantive rules in the Lake Malawi/Niassa/Nyasa sub‑basin of the Zambezi Watercourse
(Springer, 2023)questions regarding how riparian states determine “who gets what, where, and why” in a shared watercourse. To facilitate peaceful coexistence, substantive rules—“equitable and reasonable utilisation (ERU)” and “the duty ... -
Boundless baryons: how diffuse gas contributes to anisotropic tSZ signal around simulated three hundred clusters
(Oxford University Press, 2023)Upcoming advances in galaxy surveys and cosmic microwave background data will enable measurements of the anisotropic distribution of diffuse gas in filaments and superclusters at redshift z = 1 and beyond, observed through ... -
Boys are victims, too: the influence of perpetrators’ age and gender in sexual coercion against boys
(SAGE Publications, 2018)Sexual coercion among adolescent boys in South Africa is an underresearched topic despite the frequency of such events. Although quantitative research has illuminated the prevalence of sexual coercion toward boys, it has ... -
Boys Are Victims, Too: The Influence of Perpetrators’ Age and Gender in Sexual Coercion Against Boys

Boys or girls? Sex preferences declared in African and South-Asian demographic surveys
(Elsevier, 2023)In this interview with Jean-Pierre Bouchard, demographers Michel Garenne and Nancy Stiegler explore sex-preferences for girls or for boys expressed by women who responded to DHS surveys in 29 African and 10 Asian countries. ... -
Breaking baryon-cosmology degeneracy with the electron density power spectrum
(IOP Publishing, 2022)Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that are robust against these uncertainties, or ... -
Breaking new ground : the need for a protocol to the African Charter on the abolition of the death penalty in Africa
(African Human Rights Law Journal, 2005)The 1980s saw the drafting and adoption of international treaties on the abolition of the death penalty. In the European and Inter-American human rights systems, steps have been taken to abolish the death penalty by means ... -
Breaking the mold of disciplinary area studies
(Indiana University Press, 2016)At the outset of an edited volume on Intellectuals and African Development, the question is posed about what went wrong.1 The call for self-reflection perhaps anticipates a further question—about how to account for the ... -
Breastfeeding advice for reality: Women's perspectives on primary care support in South Africa

Brexit: some implications for African higher Education
(Taylor & Francis, 2018)This article considers how the decisions of the UK government, following the Brexit referendum, may impact on higher education in Africa. Ghana and South Africa are the two countries chosen to exemplify the claim that ... -
A bridge over the computer science graduate skill gap
(2013)Universities are increasingly required to respond to the ever evolving needs of an ever more sophisticated and globalised workplace, which requires well-rounded workers with more than mere technical knowledge. Employers ... -
Bridging communications across the digital divide
(CTIT, 2004)Connecting people across the Digital Divide is as much a social effort as a technological one. We are developing a community-centered approach to learn how interaction techniques can compensate for poor communication across ... -
Bridging the gap between theory and practice: Reviewing the functions and powers of local government in South Africa
(Commonwealth Journal of Local Governance, 2009)The purpose of this practice note to evaluate the current allocation of functions and powers in the Constitution, and furthermore to propose a set of criteria to guide decisions on where powers and functions are best ... -
The bright extragalactic ALMA redshift survey (BEARS) – II. Millimetre photometry of gravitational lens candidates
(Oxford University Press, 2023)We present 101- and 151-GHz ALMA continuum images for 85 fields selected from Herschel observations that have 500-μm flux densities >80 mJy and 250–500-μm colours consistent with z > 2, most of which are expected to be ... -

Bringing together knowledge and capabilities: a case study of engineering graduates
(Springer Verlag, 2016)In contemporary times there is a renewed focus on the purposes of university education in science or engineering, especially inemerging economycontexts like South Africa where the massification of higher education is in ... -
Broad Spectrum Anti-Bacterial Activity and Non-Selective Toxicity of Gum Arabic Silver Nanoparticles
(MDPI, 2022-02-04)Silver nanoparticles (AgNPs) are the most commercialized nanomaterials and presumed to be biocompatible based on the biological effects of the bulk material. However, their physico-chemical properties differ significantly ... -
Broad-band radio polarimetry of disc galaxies and AGN with KAT-7
(Oxford University Press, 2020-10-24)We report broad-band (1.2–1.9 GHz) radio continuum observations at arcminute resolutions of two nearby disc galaxies, NGC 1808 and NGC 1097, and four active galactic nuclei (AGN)-powered radio sources: PKS B1934−638, PKS ...
