Constraining the bright-end of the UV luminosity function for z ~ 7-9 galaxies: results from CANDELS/GOODS-South
(OUP, 2013)The recent Hubble Space Telescope near-infrared imaging with the Wide-Field Camera #3 (WFC3) of the GOODS-South field in the CANDELS program covering nearly 100 arcmin2, along with already existing Advanced Camera for ... -
Constraining the growth rate by combining multiple future surveys
(IOP Publishing, 2020)The growth rate of large-scale structure provides a powerful consistency test of the standard cosmological model and a probe of possible deviations from general relativity. We use a Fisher analysis to forecast constraints ... -
Constraining the intergalactic medium at z ≈ 9.1 using LOFAR Epoch of Reionization observations
(Advance access publications, 2020)We derive constraints on the thermal and ionization states of the intergalactic medium (IGM) at redshift ≈ 9.1 using new upper limits on the 21-cm power spectrum measured by the LOFAR radio telescope and a prior on the ... -
Constraining the magnetic field geometry of the millisecond pulsar psrj0030+0451 from joint radio, thermal x-ray, and γ-ray emission
(EDP Sciences, 2023)Context. With the advent of multi-wavelength electromagnetic observations of neutron stars - spanning many decades in photon energies - from radio wavelengths up to X-rays and γ-rays, it has become possible to significantly ... -
Constraining the neutrino mass using a multitracer combination of two galaxy surveys and cosmic microwave background lensing
(Oxford University Press, 2022)Measuring the total neutrino mass is one of the most exciting opportunities available with next-generation cosmological data sets. We study the possibility of detecting the total neutrino mass using large-scale clustering ... -
Constraining the reionization history using deep learning from 21-cm tomography with the Square Kilometre Array
(Oxford University Press, 2020)Upcoming 21-cm surveys with the SKA1-LOW telescope will enable imaging of the neutral hydrogen distribution on cosmological scales in the early Universe. These surveys are expected to generate huge imaging data sets that ... -
Constraints on anisotropic cosmic expansion from supernovae
(Edp Sciences, 2013)AIMS. We test the isotropy of the expansion of the Universe by estimating the hemispherical anisotropy of supernova type Ia (SN Ia) Hubble diagrams at low redshifts (z < 0.2). METHODS. We compare the best fit Hubble ... -
Constraints to implementing an equity-promoting staff allocation policy: understanding key actors perspectives affecting implementation in South Africa
(Oxford University Press, 2012)Much of current research on issues of equity in low- and middle-income countries focuses on uncovering and describing the extent of inequities in health status and health service provision. In terms of policy responses ... -
A constricted agricultural system: Cartels, collusion and corporate farming
(2014-07)A constricted agricultural system: cartels, collusion and corporate farming Nothing happens in a vacuum, let alone an agricultural system. South Africa’s has been shaped by very particular historical forces: colonisation, ... -
Construals of agency in the testimony of Colin de Souza
(Academia Press, 2009)In this paper, I analyse the testimony of Colin de Souza given before South Africa's Truth and Reconciliation Commission (TRC) in the mid-1990s.1 My aim is to explore how De Souza projects an identity of himself as 'agentive', ... -
Constructing pre-trial detention indicators for African contexts: Problems and proposals
(Dullah Omar Institute, 2015)This discussion paper arose from the conundrum faced by a paralegal organisation working in an African country in demonstrating both that pre-trial detention is a problem in that country, and that their work has an impact ... -
Constructions of students as clients or partners in knowledge creation?
(Australian Academic Press, 2013)This study explored notions of ‘the student’ within the South African higher education context. Qualitative data from interviews with twenty-three executive and senior Student Affairs staff and practitioners were collected ... -
Consumption patterns of street food consumers in Cape Town
(South African Association of Family Ecology and Consumer Sciences (SAAFECS)., 2016)Street foods (SF) contribute significantly to the diet of people living in low- and middle-income countries, however there is a paucity of data on consumption patterns of SF. Since many South Africans consume SF regularly, ... -
Contagion risk in equity markets during financial crises and Covid-19: A comparison of developed and emerging markets
(Alexandru Ioan Cuza University Press, 2022)This study compared the impact of the Global Financial Crisis (GFC) and the COVID-19 pandemic on financial market contagion between developed and emerging markets. A DCC-GARCH model was employed to test the contagion effects ... -
Contaminants of emerging concern (cecs) and male reproductive health: Challenging the future with a double-edged sword
(MDPI, 2023)Approximately 9% of couples are infertile, with half of these cases relating to male factors. While many cases of male infertility are associated with genetic and lifestyle factors, approximately 30% of cases are still ... -
Contemporaneous opening of the Alpine Tethys in the Eastern and Western Alps: Constraints from a Late Jurassic gabbro intrusion age in the Glockner Nappe, Tauern Window, Austria
(Springer, 2021)Metabasic rocks of the ophiolitic sequences of the Glockner Nappe and Eclogite Zone in the south-central Tauern Window, Austria, reveal important insights into rifting and spreading of the Alpine Tethys. U–Pb dating of ... -
Contemporary Problems of Teaching and Learning in Mathematics Education
(City University of New York., 2021)The way mathematics teaching and learning activities are presented to learners can make them hate or like the subject. The question of accomplishing the mathematics education of the learner from primary to post-secondary ... -
Contestations of the meanings of love and gender in a university students' discussion
(UNISA PressRoutledge, 2013)Love is a fluid and complex concept that is difficult to define comprehensively. Its expressions, however, show that love is not only gendered but also influenced by one's social and economic positioning. Family ... -
