Analysis of human resources for health strategies and policies in 5 countries in Sub-Saharan Africa, in response to GFATM AND Pepfar-funded HIV-activities
(BioMed Central -The Open Access Publisher, 2013)BACKGROUND: Global Health Initiatives (GHIs), aiming at reducing the impact of specific diseases such as Human Immunodeficiency Virus (HIV), have flourished since 2000. Amongst these, PEPFAR and GFATM have provided ... -
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 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 ... -
'And I have been told that there is nothing fun about having sex while you are still in high school': Dominant discourses on women's sexual practices and desires in Life Orientation programmes at school
(University of the Free State, 2015)Young women's sexuality is a contested terrain in multiple ways in contemporary South Africa. A growing body of work in the context of HIV and gender-based violence illustrates how young women find it challenging to ... -
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 ... -
Annealing effect of hybrid solar cells based on poly (3-hexylthiophene) and zinc-oxide nanostructures
(Elsevier, 2013)The structural growth and optical and photovoltaic properties of the organic–inorganic hybrid structures of zinc oxide (ZnO)-nanorods/poly-3-hexylthiophene (P3HT) and two variations of organic polymer blends of ZnO/ ... -
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 ... -
Antibacterial activities of bacteria isolated from the marine sponges Isodictya compressa and Higginsia bidentifera collected from Algoa Bay, South Africa
(MDPI AG, 2017)Due to the rise inmulti-drug resistant pathogens and other diseases, there is renewed interest in marine sponge endosymbionts as a rich source of natural products (NPs). The South African marine environment is rich in ... -
Antibiotic prescription patterns of South African general medical practitioners for treatment of acute bronchitis
(South African Medical Association, 2017)Background: Antibiotic resistance is a significant public health problem. Prudent use of antibiotics is crucial in reducing this resistance. Acute bronchitis is a common reason for consultations with general medical ... -
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 Gram-positive cocci in pregnant mothers with aerobic vaginitis
(Infection Control Africa Network (ICAN), 2016)The vaginal microbiota of a healthy asymptomatic woman consists of an extensive diversity of anaerobic and aerobic bacterial genera and species dominated by the microaerophilic genus Lactobacillus , known to inhibit the ... -
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 ...
