Anaerobes and bacterial vaginosis in pregnancy: virulence factors contributing to vaginal colonisation
(Multidisciplinary Digital Publishing Institute, 2014)The aetiology and pathogenesis of bacterial vaginosis (BV) is unclear but it appears to be associated with factors that disrupt the normal acidity of the vagina thus altering the equilibrium between the normal vaginal ... -
Analysing the professional development of teaching and learning from a political ethics of care perspective
(Routledge, 2014)This paper uses Tronto’s political ethics of care as a normative framework to evaluate a model of teaching and learning professional development. This framework identifies five integrated moral elements of care – ... -
The analysis of indexed astronomical time series – X. Significance testing of O − C data
(Oxford University Press, 2006)It is assumed that O − C (‘observed minus calculated’) values of periodic variable stars are determined by three processes, namely measurement errors, random cycle-to-cycle jitter in the period, and possibly long-term ... -
The analysis of indexed astronomical time series – XI. The statistics of oversampled white noise periodograms
(Oxford University Press, 2015)The distribution of the maxima of periodograms is considered in the case where the time series is made up of regularly sampled, uncorrelated Gaussians. It is pointed out that if there is no oversampling, then for large ... -
The analysis of indexed astronomical time series – XII. The statistics of oversampled Fourier spectra of noise plus a single sinusoid
(Oxford University Press, 2015)With few exceptions, theoretical studies of periodogram properties focus on pure noise time series. This paper considers the case in which the time series consists of noise together with a single sinusoid, observed at ... -
The analysis of irregularly observed stochastic astronomical time-series – I. Basics of linear stochastic differential equations
(Oxford University Press, 2005)The theory of low-order linear stochastic differential equations is reviewed. Solutions to these equations give the continuous time analogues of discrete time autoregressive time-series. Explicit forms for the power ... -
An analysis of pulsation periods of long period
(Royal Statistical Society, 2007)Summary: We report the results of a period change analysis of time series observations for 378 pulsating variable stars. The null hypothesis of no trend in expected periods is tested for each of the stars. The tests are ... -
An analysis of the current and future deployment of Information Systems and Technology at the University of the Western Cape
(Dept of Information Systems, Univ. of the Western Cape, 2000)In order to successfully deploy information technology and information systems, any organisation must have a strategy indicating where its business is going, an understanding of the information systems that will help to ... -
An analysis of voice over Internet Protocol in wireless mesh networks
(IEEE, 2014)The paper focuses on analyzing the affects of wireless mesh networks with some mobile nodes on Voice over Internet Protocol service quality. Our interest is to examine this in simulation to learn how to better deploy voice ... -
An analysis of what has been "lost" in the interpretation and transcription process of selected TRC testimonies
(Department of General Linguistics, Stellenbosch University, 2006)The main aim of this research is to evaluate “what has been lost” in the simultaneous interpretation and transcription processes of selected Truth and Reconciliation Commission (TRC) testimonies. The testimonies under ... -
ANCAEE: A novel clustering algorithm for energy efficiency in wireless sensor networks
(Scientific Research Publishing, 2011)One of the major constraints of wireless sensor networks is limited energy available to sensor nodes because of the small size of the batteries they use as source of power. Clustering is one of the routing techniques that ... -
The Anglican Church and Feminism: Challenging the patriarchy of our faith
(2013)Gender-based violence is a problem in most Southern African countries and yet it has generally received little attention from governments and civil society—including Christian churches. In recent years, some churches have ... -
Antarctic Dry Valley mineral soils contain unexpectedly high levels of microbial biomass
(Springer Verlag, 2002)We have applied bioluminescent ATP detection methods to microbial enumeration in Antarctic Dry Valley mineral soils, and validated our ATP data by two independent methods. We have demonstrated that ATP measurement is ... -
The Anthropocene crisis and higher education: A fundamental shift
(South African Association for Research and Development in Higher Education (SAARDHE), 2016)This article seeks to address a fundamental shift that has occurred in reality; a displacement that requires us to critically account for the ways in which knowledge is both being produced and taught at universities. The ... -
Antimicrobial activities of a novel biflavonoid and other constituents from Rhus natalensis
(Academic Journals, 2013)Phytochemical studies on Rhus natalensis root bark collected from Kenya led to the isolation and identification of a new biflavonoid (3-(1-(2,4-dihydroxyphenyl)-3,3-bis(4-hydroxyphenyl)-1-oxopropan-2- yl)-7-methoxy-4H-ch ... -
Antimicrobial activity of two South African honeys produced from indigenous Leucospermum cordifolium and Erica species on selected micro-organisms
(BioMed Central, 2008)Background: Honey has been shown to have wound healing properties which can be ascribed to its antimicrobial activity. The antimicrobial activity can be effective against a broad spectrum of bacterial species especially ... -
Antimicrobial-resistant Klebsiella species isolated from free-range chicken samples in an informal settlement
(Termedia Publishing House, 2012)Sub-therapeutic doses of antimicrobial agents are administered routinely to poultry to aid growth and to prevent disease, with prolonged exposure often resulting in bacterial resistance. Crossover of antibiotic resistant ... -
Apartheid's university: Notes on the renewal of the Enlightenment
(CODESRIA, 2007)This paper sets to work on strategies for forging new and critical humanities at the institutional site of the university that appears to be trapped in the legacies of apartheid. The paper suggests that the university's ... -
Application of Lazarus's cognitive transactional model of stress-appraisal-coping in an undergraduate mental health nursing programme in the Western Cape, South Africa
(AFAHPER-SD, 2014)This article describes how the cognitive transactional model of stress-appraisal-coping can be applied in the sense making process for students working in the challenging mental health care environment. Primary and secondary ...
