The influence of interpretation on visitors behaviour in the Kruger National Park
(AJHTL, 2015)It is a well-known fact that interpretation influences visitors’ behaviour to be more in line with respect for the environment, philanthropic support for conservation and generally environmental sound behaviour. This study ... -
Establishing the relative competitiveness of South African banking shares: a Kalman filter approach
(Clute Institute, 2015)It is argued that the Basel III Accord will undermine the ROE of South African banks, and with the downgrading of South African banks during August 2014, will force investors to revaluate South African banking shares as ... -
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 ... -
Online service attidtudes, site attitudes and site involvement in the South African domestice airline industry: a gender perspective
(Prof. Ansie Lessing, 2015)The airline industry experienced rapid growth and airlines are competing for new customers. The industry is experiencing a change in customer behaviour as customers are becoming less loyal and harder to satisfy. The online ... -
Identifying the comparative advantage of products and industries of South Africa's Mpumalanga province
(University of South Africa (UNISA), 2015)Knowledge of a region’s comparative advantage may dictate its industrial development agenda and realistic export opportunities. Through the effective targeting of specific sectors and industries within the South African ... -
Synthesis characterization and biological activities of coordination compounds of 4-hydroxy-3-nitro-2h-chromen-2-one and its aminoethanoic acid and pyrrolidine-2-carboxylic acid mixed ligand complexes
(Hindawi, 2017)Coordination compounds of 4-hydroxy-3-nitro-2H-chromen-2-one and their mixed ligand complexes with aminoethanoic acid and pyrrolidine-2-carboxylic acid were synthesized by the reaction of Cu(II) and Zn(II) salts in molar ... -
The creation of synthetic digital ground-truth images of historic cosmic ray data recordings
(Springer, 2017)The aim of this paper is to develop a set of algorithms for the automated construction of synthetic digital ground truth images from historic cosmic ray recordings. These images can subsequently be used to test data ... -
A support programme for foundation phase English Second Language educators to improve the teaching of phonological awareness
(North-West University (South Africa), Vaal Triangle Campus, 2015)This study aimed to explore the knowledge, perceptions and skills of Foundation Phase English Second Language educators as determinants for developing a support programme for educators to improve their phonological ... -
Probing Vela pulsar down to 20 GeV with H.E.S.S. II observations
(AIP, 2017)Observations of the Vela pulsar (PSR B0833-45) with the High Energy Stereoscopic System phase II array (H.E.S.S. II) have resulted in a high-significance detection of its pulsed emission down to 20 GeV. The very low-energy ... -
The H.E.S.S. II GRB observation scheme
(AIP, 2017)Gamma-ray bursts (GRBs) are some of the Universe’s most enigmatic and exotic events. However, at energies above 10 GeV their behaviour remains largely unknown. Although space based telescopes such as the Fermi-LAT have ... -
Diagnosing relativistic particle acceleration in AGN jets
(AIP, 2017)Mildly relativistic, oblique shocks are generally considered to be among the most plausible sites of relativistic particle acceleration and the subsequent production of strongly variable, polarized multi-wavelength emission ... -
Target of opportunity observations of blazars with H.E.S.S.
(AIP, 2017)The very high energy (VHE, E > 100 GeV) sky is dominated by blazars, radio-loud active galactic nuclei whose relativistic jet is closely aligned with the line of sight. Blazars are characterized by rapid variability at all ... -
The complex VHE and multiwavelength flaring activity of the FSRQ PKS 1510-089 in May 2015
(AIP, 2017)The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. ... -
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 ... -
The extended jet in AP Librae as the source of the VHE γ-ray emission
(AIP, 2017)Most modeling attempts of blazars use a small emission zone located close to the central black hole in order to explain the broad-band spectral energy distribution. Here we present a case where additionally to the small ... -
Synthesis and application of novel ruthenium catalysts for high temperature alkene metathesis
(MDPI, 2017)Four pyridinyl alcohols and the corresponding hemilabile pyridinyl alcoholato ruthenium carbene complexes of the Grubbs second generation-type RuCl(H2IMes)(O^N)(=CHPh), where O^N = 1-(2′-pyridinyl)-1,1-diphenyl methanolato, ... -
Health clinic gardens in North-West Province, South Africa, as complex social-ecological systems
(North-West University (South Africa), 2016)The world’s urban population (54%) is currently increasing. The fastest growth rates are expected to occur in urban areas of Africa and Asia. Since urban areas will continue to expand, ecological studies should also take ... -
Double product and psychological distress in a bi-ethnic urban South African cohort : the SABPA study
(North-West University (South Africa) , Potchefstroom Campus, 2016)Argument: Hypertension contributes to the development of cardiovascular diseases. Several factors contribute to the development of hypertension, such as obesity, alcohol abuse and psychological distress. Black Africans ... -
The neoliberal governmentality of land-deals : a Foucauldian analysis of South-South development cooperation
(North-West University (South Africa), Potchefstroom Campus, 2015)In the past decade, Africa's agricultural land has been subjected to acquisition from a variety of actors across the globe. Their interest in arable soil forms part of a broader attempt to either promote domestic food ... -
Biology and ecology of fishes of the Senqu River, Lesotho
(North-West University (South Africa), Potchefstroom Campus, 2015)In this study, fish were used as bio-indicators to evaluate the present ecological state (PES) in different reaches of the Senqu River downstream of the proposed Polihali Dam in Lesotho. However, information regarding fish ...
