Asymmetric cointegration and causality effects between financial development and economic growth in South Africa
(Emerald Group Publishing, 2015)Purpose – The purpose of this paper is to investigate asymmetric cointegration and causality effects between financial development and economic growth for South African data spanning over the period of 1992-2013. Desi ... -
Asymmetric dimethylarginine and l-homoarginine prospectively relate to carotid wall thickness in a South African cohort
(Springer, 2020)Background and aims The L-arginine derivatives asymmetric (ADMA) and symmetric dimethylarginine (SDMA), as well as L-homoarginine may have opposing effects in the pathogenesis of atherosclerosis. We aimed to investigate ... -
Asymmetric dimethylarginine and symmetric dimethylarginine prospectively relates to carotid wall thickening in black men: the SABPA study
(Springer, 2017)The relationship of both asymmetric (ADMA) and symmetric (SDMA) dimethylarginine with carotid wall thickness is inconclusive especially among black populations. We aimed to compare carotid intima media thickness (cIMT) and ... -
Asymptotic analysis of solitons and double layers at the acoustic speed
(Cambridge Univ Press, 2017)In this paper, we consider the asymptotic behaviour of solitons and double layers. By using the Sagdeev pseudopotential formalism, a Taylor series expansion is used to derive the asymptotic behaviour. For solitons and ... -
Asymptotics of the smallest singular value of a class of toeplitz–generated matrices and related finite rank perturbations
(Springer Link, 2013)Square matrices of the form Xn = Tn+fn(T −1 n ) ∗ , where Tn is an n×n invertible banded Toeplitz matrix and fn some positive sequence are considered. The norms of their inverses are described asymptotically as their ... -
Asymptotics, finite-sample comparisons and applications for two-sample tests with functional data
(Elsevier, 2019)We consider two-sample tests for functional data with observations which may be uni- or multi-dimensional. The new methods are formulated as -type criteria based on empirical characteristic functions and are convenient ... -
Athletic-ideal internalisation: lived experiences of female students
(NWU, 2020)Research has shown a clear relationship between the thin-ideal internalisation, disturbed eating and body-related disturbances. With regard to athletic internalisation, the relationship with these outcomes appears to be ... -
Atmospheric boundary layer top height in South Africa: measurements with lidar and radiosonde compared to three atmospheric models
(EGU, 2014)Atmospheric lidar measurements were carried out at Elandsfontein measurement station, on the eastern Highveld approximately 150 km east of Johannesburg in South Africa throughout 2010. The height of the planetary ... -
Atmospheric dry and wet deposition of sulphur and nitrogen species and assessment of critical loads of acidic deposition exceedance in South Africa
(ASSAf, 2011)We tested the hypothesis that acidic atmospheric pollution deposition, originating from the South African central industrial area, poses an environmental threat across a larger region within the dispersal footprint. A ... -
Atmospheric ions and nucleation: a review of observations
(EGU, 2011)This review is based on ca. 260 publications, 93 of which included data on the temporal and spatial variation of the concentration of small ions (<1.6 nm in diameter) especially in the lower troposphere, chemical composition, ... -
Atmospheric trace metals measured at a regional background site (Welgegund) in South Africa
(EGU, 2017)Atmospheric trace metals can cause a variety of health-related and environmental problems. Only a few studies on atmospheric trace metal concentrations have been conducted in South Africa. Therefore the aim of this study ... -
Attachment and psychological well-being among adolescents with and without disabilities in Kenya: the mediating role of identity formation
(Elsevier, 2013)The current study is aimed at evaluating the relationship between attachment and identity development, and their influence on psychological well-being in adolescents with and without disabilities in Kenya. The sample was ... -
Attachment relationships of preschool-aged children of mothers with HIV and HIV-related psychosis
(Taylor & Francis, 2016)Children from mothers with HIV-related psychosis are frequently raised in challenging contexts, yet the extent to which these children grow up in insecure or disordered attachment relationships is unknown. Using the Strange ... -
An attempt to define the constitutive elements of a pentecostal spirituality
(AOSIS, 2015)Pentecostal spirituality is defined as the integration of beliefs and practices into the affections that are themselves evoked and expressed by those practices and beliefs. This article investigates these practices and ... -
Attempting to define a Pentecostal Hermeneutics
(University of Stellenbosch, 2015)What is distinctive about Pentecostals' reading of the Bible? In what way do Pentecostal people read the Bible so that they reach different conclusions than believers of other denominations? Is it possible to speak of a ... -
Attempting to develop a Pentecostal theology of worship
(AOSIS, 2016)Pentecostals affirm the power of Pentecost in worship where they experience the Spirit's revelation of Christ and teach and preach about worship. However, Pentecostal theologians have not written much about a theology of ... -
Attention distribution and cognitive load in a subtitled academic lecture: L1 vs. L2
(JEMR, 2014)In multilingual classrooms, subtitling can be used to address the language needs of students from different linguistic backgrounds. The way students distribute their visual and cognitive resources during a lecture is ... -
Attenuated brain-derived neurotrophic factor and hypertrophic remodelling: the SABPA study
(Springer Nature, 2015)Brain-derived neurotrophic factor (BDNF) has been linked to neurological pathologies, but its role in cardiometabolic disturbances is limited. We aimed to assess the association between serum BDNF levels and structural ... -
Attenuated IGF-1 predicts all-cause and cardiovascular mortality in a Black population: a five-year prospective study
(Sage Publications Ltd, 2016)Background: Inconsistent findings are reported on whether insulin-like growth factor-1 (IGF-1) is protective or harmful in predicting hypertension, carotid wall thickness and mortality. We determined the five-year ... -
Attenuated NOx responses and myocardial ischemia, a possible risk for structural vascular disease in African men: the SABPA study
(Nature Publishing Group, 2014)Chronically elevated blood pressure has been associated with impaired NO-mediated vasodilation and structural vascular disease risk. This study aimed to determine whether significant associations exist regarding NO metabolite ...
