Intelligente beheer van ’n hernubare, energiedoeltreffende tenk vir melkboerderye
(AOSIS, 2015)
To reduce strain on Eskom and decrease the cost for producing dairy products, an energy-efficient
bulk storage tank using solar power was designed. The system uses thermoelectric cooling
modules as a supporting cooling ...
Partial and average copulas and association measures
(Institute of Mathematical Statistics, 2015)
For a pair (Y1,Y2) of random variables there exist several measures of association that characterize the dependence between Y1 and Y2 by means of one single value. Classical examples are Pearson’s correlation coefficient, ...
Uniform in bandwidth consistency of kernel estimators of the density of mixed data
(Institute of Mathematical Statistics, 2015)
We establish a general uniform in bandwidth consistency result for kernel estimators of the unconditional and conditional joint density of a distribution, which is defined by a mixed discrete and continuous random variable
The depletion of narrative resources in the Kenyan trade union movement
(Virtus Interpress, 2015)
We discuss in this study the problems of mobilization and effectiveness faced by Kenyan trade unions. In a country with high levels of unemployment and weak labour legislation, it is imperative that the labour movement ...
Is the South African exchange rate volatile? Application of the arch framework
(Virtus Interpress, 2015)
This study applies the autoregressive conditional heteroscedasticity (ARCH) model to forecast exchange rate volatility in South Africa for the period 1990Q1 to 2014Q2. The ARCH (1) and ARCH (2) models were constructed using ...
Demographic structure and genetic diversity of Mauremys leprosa in its northern range reveal new populations and a mixed origin
(Deutsche Gesellschaft für Herpetologie und Terrarienkunde, 2015)
Freshwater turtle species are still poorly understood, and many species are in decline due to unsustainable trade as well as human alteration and degradation of freshwater ecosystems. Mauremys leprosa is a freshwater ...
Climate change, complex interdependence and development: assessment of Lesotho-South Africa relations
(Business Perspectives, 2015)
Climate change and its negative effects on the developing states are a reality of which there is a need to focus on likely
mitigation and adaptive strategies to ensure sustainable development. Industrial development back ...
Of God's image, violence against women and feminist reflections
(Studia Historiae Ecclesiasticae, 2015)
This article interrogates what appears to be an inconsistency - the enduring prevalence of Christianity and the surge of gender-based violence (henceforth GBV) in Botswana, particularly as evidenced by murder-suicides. It ...
Early science with the Karoo Array Telescope: a mini-halo candidate in galaxy cluster Abell 3667
(Oxford University Press, 2015)
Abell 3667 is among the most well-studied galaxy clusters in the Southern hemisphere. It is known to host two giant radio relics and a head–tail radio galaxy as the brightest cluster galaxy. Recent work has suggested the ...
