Implementing the countercyclical capital buffer in South Africa: practical considerations
(AOSIS, 2015)The Basel II regulatory framework significantly increased the resilience of the banking system, but proved ineffective in preventing the 2008/9 financial crisis. The subsequent introduction of Basel III aimed, inter ... -
Implementing the Multifactor Leadership Questionnaire (MLQ) in a challenging context: results from a large-scale quantitative study
(Emerald, 2019)Purpose An emphasis on school performance is not just a national issue, but must be examined within the global context. Successful leadership is ensured by school leaders’ compliance to a set of basic practices within ... -
Implementing the uses of ict in agro - products to improve market information services: challenges and opportunities for Tanzania
(Global business and technology association, 2012)The need to provide agricultural information for improving agro products market information has led to emergence of numerous ICT-based projects in developing country. These projects aim at promoting commercialization of ... -
Implemetation of fuzzy logic on magnetic bering model
(ASSAf, 2020)Spectral analysis using wavelet, Lomb–Scargle and maximum entropy techniques of the proxy rainfall record of northeastern South Africa based on annual carbon isotope (δ13C) data obtained from baobab trees for the period ... -
Implications for health education and intervention strategies arising from children's caregivers concerns following successful malaria control
(Elsevier, 2012)Malaria is still responsible for 10% of the total disease burden in Africa. This study was an empirical investigation addressing the extent to which, and the ways in which, sociocultural, family-based, demographic and ... -
Implications of Sepedi/English code switching for ASR systems
(Pattern recognition association of South Africa (PRASA), 2013)Code switching (the process of switching from one language to another during a conversation) is a common phenomenon in multilingual environments. Where a minority and dominant language coincide, code switching from the ... -
The implications of simple estimates of the 2D outerscale based on measurements of magnetic islands for the modulation of galactic cosmic-ray electrons
(IOP Publishing, 2019)The behavior of the 2D turbulence power spectrum at the lowest wavenumbers has a significant effect on the perpendicular diffusion coefficients of charged particles in the heliosphere derived from various scattering theories, ... -
Implications of time-dependent injection in relativistic jets
(AIP, 2017)Rapid blazar flaring events and their rich behavior require time-dependent modeling. One important approach is time-dependent injection causing non-linear cooling effects, since the inevitable SSC cooling depends on the ... -
Implications of Voyager 1 observations beyond the heliopause for the local interstellar electron spectrum
(IOP Publishing, 2014)Cosmic-ray observations made by the Voyager 1 spacecraft outside the dominant modulating influence of the heliosphere finally allow the comparison of computed galactic spectra with experimental data at lower energies. These ... -
Implicit convolution Fokker-Planck equations: extended Feller convolution
(Springer, 2020)Fokker-Planck equations are partial differential equations in the transition function of the Markov process. In the evolution equation approach, we re-write partial differential equations as ordinary differential equations ... -
Importance of bovine mastitis in Africa
(Cambridge Univ Press, 2017)Bovine mastitis is an important animal production disease that affects the dairy industry globally. Studies have estimated the prevalence of this disease in approximately 30% of African countries, with the highest prevalence ... -
The importance of creative participatory planning in the public place-making process
(SAGE Publications, 2014)The idea of ‘place’ has long been central to the planning and design practice. Recent trends illustrate increased intervention in the ‘experience’ and ‘feeling’ of places, in order to influence and enhance community dynamics. ... -
Importance of detailed soil information for hydrological modelling in an urbanized environment
(MDPI, 2020)Soil information is critical in watershed-scale hydrological modelling; however, it is still debated which level of complexity the soil data should contain. In the present study, we have compared the effect of two levels ... -
Imposex assessment and tributyltin levels in sediments along the Atlantic coast of South Africa
(Elsevier, 2018)Female marine gastropods develop imposex (growth of penis/vas deferens) when exposed to TBT (tributyltin). Ours, is the first report of an imposex survey associated with TBT in sediment along 920 km of South Africa's ... -
An improved formulation of the underground mine scheduling optimisation problem when considering selective mining
(ORSSA, 2015)The use of mixed integer programming is a modelling approach well suited to formulate the mine scheduling optimisation problem for both open pit and underground mining. The resolution applied for discretising the problem, ... -
Improved metathesis lifetime: chelating pyridinyl-alcoholato ligands in the second generation Grubbs precatalyst
(MDPI, 2014)Hemilabile ligands can release a free coordination site “on demand” of an incoming nucleophilic substrate while occupying it otherwise. This is believed to increase the thermal stability and activity of catalytic systems ... -
Improved PCR diagnostics using up-to-date in silico validation: an F-gene RT-qPCR assay for the detection of all four lineages of peste des petits ruminants virus
(Elsevier, 2019)Peste des petits ruminants (PPR) is a globally significant disease of small ruminants caused by the peste des petits ruminants virus (PPRV) that is considered for eradication by 2030 by the United Nations Food and Agriculture ... -
Improved strategies for sequence-independent amplification and sequencing of viral double-stranded RNA genomes
(Microbiology Society, 2009)This paper reports significant improvements in the efficacy of sequence-independent amplification and quality of sequencing of viruses with segmented double-stranded RNA (dsRNA) genomes. We demonstrate that most remaining ... -
Improved transition models for cepstral trajectories
(Pattern recognition association of South Africa (PRASA), 2012)We improve on a piece-wise linear model of the trajectories of Mel Frequency Cepstral Coefficients, which are commonly used as features in Automatic Speech Recognition. For this purpose, we have created a very clean ...
