A checklist for testing measurement invariance
(Taylor & Francis, 2012)The analysis of measurement invariance of latent constructs is important in research across groups, or across time. By establishing whether factor loadings, intercepts and residual variances are equivalent in a factor ... -
A checklist for testing measurement invariance
(Taylor & Francis, 2012)The analysis of measurement invariance of latent constructs is important in research across groups, or across time. By establishing whether factor loadings, intercepts and residual variances are equivalent in a factor model ... -
Chemical and structural characterization of char development during lignocellulosic biomass pyrolysis
(Elsevier, 2017)The chemical and structural changes of three lignocellulosic biomass samples during pyrolysis were investigated using both conventional and advanced characterization techniques. The use of ATR-FTIR as a characterization ... -
Chemical Composition and Dry Matter Yield of Cowpea (Vigna unguiculate L Walp) Haulms as Fodder for Ruminants
(Kamla-Raj, 2016)The purpose of the study was to determine chemical composition and dry matter yield of cowpea haulms (Sejwaleng, Lebudu and Morathathane) grown in Limpopo Province, South Africa. Randomized complete block design was used ... -
The chemical composition and fluxes of atmospheric wet deposition at four sites in South Africa
(Elsevier, 2016)South Africa is the economic hub of southern Africa and is regarded as an important source region of atmospheric pollutants. A nitrogen dioxide (NO2) hotspot is clearly visible from space over the South African Mpumalanga ... -
Chemical composition, but not specific surface area, affects calcium retention of nanostructured calcium compounds in growing rats
(American Society for Nutrition, 2017)Background: Low dietary calcium intake and bioavailability may adversely affect bone health. Reducing the size of calcium compounds increases their specific surface area (SSA, expressed as m2/g) and may increase calcium ... -
Chemical composition, main sources and temporal variability of PM1 aerosols in southern African grassland
(Copernicus Publications on behalf of the European Geosciences Union, 2014)Southern Africa is a significant source region of atmospheric pollution, yet long-term data on pollutant concentrations and properties from this region are rather limited. A recently established atmospheric measurement ... -
Chemical composition, nitrogen degradability and in vitro ruminal biological activity of tannins in vines harvested from four tropical sweet potato (Ipomoea batatas L.) varieties
(Wiley, 2016)This study investigated the potential of vines from four sweet potato varieties (Tia Nong 57, Tia Nong 66, Ligwalagwala and Kenya) as alternative feed resources for ruminant livestock. The chemical composition [neutral ... -
Chemical Evaluation of South African Prickly Pear Cladodes Varieties as Fodder for Ruminants Grown in Mara ADC, South Africa
(Kamla-Raj, 2016)The aim of the study was to determine the chemical composition of South African prickly pears cladodes varieties as fodder for ruminants in Mara ADC, South Africa. The experimental field was divided into four replications ... -
Chemical oxidative polymerization of m-phenylenediamine and its derivatives using aluminium triflate as a co-catalyst
(Elsevier, 2013)Aromatic diamine monomers, including m-phenylenediamine (mPD), 2-methyl-m-phenylenediamine (2Me-mPD), 4-methyl-m-phenylenediamine (4Me-mPD) and trimethyl-mphenylenediamine (tMe-mPD), were polymerized by chemical oxidation ... -
Chemical toxicity of surface-based drinking water sources due to natural uranium pollutant around Princess Gold Mine Environs in Roodepoort, South Africa
(Springer, 2016)The activity level of natural uranium pollutant in surface-based water around Princess Gold Mine in Roodepoort, South Africa was measured using inductively coupled plasma mass spectrometry. The highest activity level of ... -
Chemically oxidative polymerization of aromatic diamines: the first use of aluminium-triflate as a co-catalyst
(Elsevier, 2013)Aromatic diamine monomers, including o-phenylenediamine (oPD), p-phenylenediamine (pPD), 4,4′-diaminodiphenylenemethane (DADPM) and benzidine (BZN), were polymerized by chemical oxidation using sodium persulfate, potassium ... -
Chemical–structural properties of South African bituminous coals: insights from wide angle XRD–carbon fraction analysis, ATR–FTIR, solid state 13C NMR, and HRTEM techniques
(Elsevier, 2015)The chemical–structural properties of four South African bituminous coals were investigated using wide angle X-ray diffraction–carbon fraction analysis (WAXRD–CFA), attenuated total reflection Fourier transform infra-red ... -
Child and adult readers' processing of foreignised elements in translated South African picturebooks: an eye–tracking study
(John Benjamins publishing company, 2013)The tension between domesticating and foreignising translation strategies is particularly strongly felt in the translation of children’s literature, and has been a key issue in many studies of such literature. However, ... -
Child's gender preference: What is the regional situation among women in Nigeria?
(SABINET, 2014)Child Gender Preference (CGP) is a socio-cultural phenomenon in Africa. It has implication on family building process by increasing fertility through short birth intervals, thus putting maternal and child health at risk. ... -
Childbearing dynamics among married women of reproductive age in Nigeria: Re–affirming the role of education
(UAPS, 2014)Nigeria ranks among the high-fertility countries in sub-Saharan Africa. Studies that examine relationship between fertility dynamics and education are important to improving maternal and child health. This study uses 2008 ... -
Childhood as continuity and newness: generational succession understood according to the theological logic of the gift
(Taylor and Francis, 2015)This article seeks to understand, in a speculative way, the relationship between a new generation and the one preceding it. After having identified two opposite extremes – the ‘continuity thesis’ and the ‘discontinuity ... -
Childhood general mental ability and midlife psychosocial work characteristics as related to mental distress, neck/shoulder pain and self-rated health in working women and men
(Japan Society of Occupational Health, 2011)Psychosocial work characteristics including high demands, lack of control and poor social support have consistently been linked to poor health as has poor general mental ability (GMA). However, less is known about the ... -
Childhood overweight and obesity patterns in South Africa: a Review
(AFAHPER-SD, 2009)The prevalence of childhood obesity has been rapidly increasing over the last decade in both developed and developing countries. To combat the increasing prevalence of childhood overweight and obesity in South Africa, it ...
