Designing mobile phone interfaces for age diversity in South Africa: “One-World” versus diverse “Islands”
(Springer, 2013)Designing for diversity is a laudable aim. How to achieve this, in the context of mobile phone usage by South African seniors, is a moot point. We considered this question from two possible perspectives: universal ... -
Designing novel possible kinase inhibitor derivatives as therapeutics against Mycobacterium tuberculosis: An in silico study
(Scientific Reports, 2019)Rv2984 is one of the polyphosphate kinases present in Mycobacterium tuberculosis involved in the catalytic synthesis of inorganic polyphosphate, which plays an essential role in bacterial virulence and drug resistance. ... -
Designing online learning environments in higher education: Building capacity of lecturers to design and facilitate blended e-pedagogy for mature students
(University of the Western Cape, 2022)Amidst the spread of COVID-19, higher education institutions (HEIs) in South Africa were compelled to offer academic programmes through online learning by utilising digital information and communication technologies (ICT) ... -
Designing the project: theoretical approaches
(HSRC Press, 2012)Education in South Africa is in crisis. Low literacy and numeracy rates, poor discipline, and a sense of despair pervade the education landscape. At the same time, educators are called upon to achieve more, with universities ... -
Designing theoretical assessments at nursing higher education institutions: A scoping review
(Stellenbosch University, 2022)Assessment in higher education remains one of the most reliable forms of assessing the effectiveness of the learning and teaching (L&T) process. Excellence in theory assessment design is, therefore, a pivotal element of ... -
Desire and language in Derrida’s 'Force of Law'
(Franz Steiner Verlag, 2009)In this article, the author proposes a reading of 'Force of Law' from two angles: boundless desire and the ‘law’ of language. The author contends that an analysis from these perspectives casts new light on the notion of ... -
Desperate times call for desperate measures: Adapting antiretroviral service delivery in the context of the COVID-19 pandemic
(SAMA, 2020)On 23 March 2020, President Cyril Ramaphosa announced a nation-wide lockdown to help curb the spread of the COVID-19 epidemic in South Africa (SA). While these containment measures are considered to have limited the ... -
The detailed forms of the LMC Cepheid PL and PLC relations
(Oxford University Press, 2007)Possible deviations from linearity of the Large Magellanic Cloud Cepheid period–luminosity (PL) and period–luminosity–colour (PLC) relations are investigated. Two data sets are studied, respectively from the Optical ... -
Detecting marine heatwaves with sub-optimal data
(Frontiers, 2019)Marine heatwaves (MHWs), or prolonged periods of anomalously warm sea water temperature, have been increasing in duration and intensity globally for decades. However, there are many coastal, oceanic, polar, and sub-surface ... -
Detecting relativistic Doppler in galaxy clustering with tailored galaxy samples
(Elsivier, 2024)We present a method to obtain a high-significance detection of relativistic effects on cosmological scales. Measurements of such effects would be instrumental for our understanding of the Universe, as they would provide ... -
Detecting the relativistic galaxy bispectrum
(IOP Publishing Ltd, 2020)The Fourier galaxy bispectrum is complex, with the imaginary part arising from leading-order relativistic corrections, due to Doppler, gravitational redshift and related lineof-sight effects in redshift space. The detection ... -
Detection of an increasing orbital period in the subdwarf B eclipsing system NSVS 14256825
(Oxford University Press, 2012)New timings of eclipses made in 2010 and 2011 are presented for the hot subdwarf B (sdB) eclipsing binary NSVS 14256825. Composed of an sdB star and a much cooler companion, with a period near 0.1104 days, this system ... -
Detection of Cross-Correlation between Gravitational Lensing and γ Rays
(American Physical Society, 2020)In recent years, many γ -ray sources have been identified, yet the unresolved component hosts valuable information on the faintest emission. In order to extract it, a cross-correlation with gravitational tracers of ... -
A detection threshold in the amplitude spectra calculated from Kepler data obtained during K2 mission.
(Oxford University Press, 2015)We present our analysis of simulated data in order to derive a detection threshold which can be used in the pre-whitening process of amplitude spectra. In case of ground-based data of pulsating stars, this threshold is ... -
Determinant of the relationship between labour force participation in South Africa for both male and female
(University of Cape Town, 2016)Reducing poverty and inequality are key challenges in South Africa. Access to the labour market and earnings differentials are the main drivers of poverty and inequality in South Africa (Leibbrandt et al.,2010). Educational ... -
Determinants and rates of retention in HIV care among adolescents receiving antiretroviral therapy in Windhoek, Namibia: A baseline cohort analysis
(BMC, 2022)Long-term engagement in HIV care is essential to achieving and maintaining viral suppression. Adolescents living with HIV (ALHIV) experience many barriers to remaining engaged in care and treatment programs. Higher ... -
Determinants of adolescent Hookah pipe use: A systematic review
(Routledge, 2019)Adolescent hookah pipe use is increasing at a rapid rate, thus posing a major public health concern globally. The hookah pipe is a gateway substance to other substances that may be more harmful. Yet, at present, little ... -
Determinants of business intelligence system acceptance in an emerging country
(Virtus Interpress, 2018)In today’s highly competitive and cumulative uncertainty in the business domain, access to organizations’ business intelligence (BI) can mean not only the difference between profit and loss but also the difference between ... -
Determinants of consumer attitude toward corporate sponsors: A comparison between a profit and non-profit sport event sponsorship
(Wiley, 2017)The purposes of the present study were to identify key attributes of sponsors that positively influence consumers’ attitude formation and to examine the moderator role of sport event types (nonprofit vs. profit). Based on ...
