Extending BEAMS to incorporate correlated systematic uncertainties
(IOP Science, 2013)New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the LSST will produce an unprecedented number of photometric supernova candidates, most with no spectroscopic data. Avoiding biases in cosmological ... -
Extending boundaries: Team teaching to embed information literacy in a university module
(UNISA, 2020)In today’s knowledge-based economy, the role of universities in preparing students to be information literate and independent thinkers and researchers is crucial. Information literacy (IL) skills enable students to become ... -
Extending the frontiers of employment regulation: the case of domestic employment in South Africa
(Faculty of Law, University of the Western Cape, 2010)Domestic workers form one of the most vulnerable and exploited sectors of the workforce in the world economy. In 2002 South Africa became one of relatively few countries to promulgate special legislation aimed at extending ... -
Extending the Hoyle-State Paradigm to 12 C + 12 C Fusion
(American Physical Society, 2022)Carbon burning is a key step in the evolution of massive stars, Type 1a supernovae and superbursts in x-ray binary systems. Determining the 12C þ 12C fusion cross section at relevant energies by extrapolation of direct ... -
Extending the nomological network of wellness at work
(Southern African Institute for Management Scientists (SAIMS), 2016)Modern-day organisations face rapid and continuous change. In order to deal with this rapidly changing and current hostile economic environment, most organisations have become increasingly dependent on a healthy and engaged ... -
Extending the variability selection of active galactic nuclei in the W-CDF-S and SERVS/SWIRE region
(EDP Sciences, 2020)Variability has proven to be a powerful tool to detect active galactic nuclei (AGN) in multi-epoch surveys. The new-generation facilities expected to become operational in the next few years will mark a new era in time-domain ... -
Extension of Security of Tenure Bill of 2015
(Institute for Poverty, Land and Agrarian Studies, University of the Western Cape, 2016)The Institute for Poverty, Land and Agrarian Studies (PLAAS) welcomes the initiative to amend the Extension of Security of Tenure Act, 62 of 1997. PLAAS is a constituent unit of the School of Government at the University ... -
Extension of the composite quality score (cqs) as an appraisal tool for prospective, controlled clinical therapy trials–A systematic review of meta-epidemiological evidence
(Public Library of Science, 2022)To conduct a survey of current meta-epidemiological studies to identify additional trial design characteristics that may be associated with significant over- or underestimation of the treatment effect and to use such ... -
Extensive recombination detected among beak and feather disease virus isolates from breeding facilities in Poland
(Microbiology Society, 2013)Beak and feather disease virus (BFDV) causes the highly contagious, in some cases fatal, psittacine beak and feather disease in parrots. The European continent has no native parrots, yet in the past has been one of the ... -
An extensive search for rapid optical variability in ultracool dwarfs
(Oxford University Press, 2013)In this paper, a summary of optical time-series photometry of 125 ultracool dwarfs is given. The observing strategy was to monitor each object continuously for 2–3 h in order to ascertain whether itwas rapidly variable. ... -
External economic arrangements and South African cities as agents of local development: Illustrations from the City of Cape Town
(GBATA, 2021)The paper examines the role of South African metropolitan cities (metros) in advancing local economic development (LED) through engagements with external actors. Globalization is increasingly changing the roles and players ... -
External stakeholders and health promoting schools: complexity and practice in South Africa
(Emerald, 2014)Purpose: This paper examines the role of two higher education institutions in the Western Cape, South Africa, and how their initiatives and collaboration brought about a particular Health Promoting Schools (HPS) program ... -
The externalisation and casualisation of farm labour in Western Cape horticulture
(Institute for Poverty, Land and Agrarian Studies, University of the Western Cape, 2003)On several Friday nights during February and March 2001, a visitor to Happiness Street1 in the Oostenberg Municipality s newly created Westbank housing project would have witnessed angry scenes. A small crowd of frustrated ... -
Extra-oral suction
(MDPI, 2023)Oral health care workers (OHCW) are exposed to pathogenic microorganisms during dental aerosol-generating procedures. Technologies aimed at the reduction of aerosol, droplets and splatter are essential. This in vivo study ... -
Extracting the global signal from 21-cm fluctuations: the multitracer approach
(Oxford University Press, 2019)The multitracer technique employs a ratio of densities of two differently biased galaxy samples that trace the same underlying matter density field, and was proposed to alleviate the cosmic variance problem. Here, we propose ... -
