Herschel PEP/HerMES: the redshift evolution of dust attenuation and of the total (UV+IR) star formation rate density
(EDP Sciences, 2013)
Using new homogeneous luminosity functions (LFs) in the far-ultraviolet (FUV) from VVDS and in the far-infrared (FIR) from Herschel/PEP and Herschel/HerMES, we studied the evolution of the dust attenuation with redshift. ...
Hermes: Cosmic infrared background anisotropies and the clustering of dusty star-forming galaxies
(American Astronomical Society, 2013)
Star formation is well traced by dust, which absorbs the
UV/optical light produced by young stars in actively starforming
regions and re-emits the energy in the far-infrared/
submillimeter (FIR/submm; e.g., Savage & ...
HerMES: Candidate gravitationally lensed galaxies and lensing statistics at submillimeter wavelengths
(American Astronomical Society, 2013)
Gravitational lensing increases the angular size and integrated flux of affected sources. It is exploited to investigate the mass distribution of the foreground lensing structures and the properties of the background lensed ...
An exploratory look at associated factors of poverty on educational attainment in Africa and in-depth multilevel modelling for Namibia.
(BER, 2013)
This study examines several indicator variables related to education
and poverty in Africa from the Demographic and Health Surveys
(DHS). Many have described income and education as one of the
fundamental determinants ...

Understanding issues of people living with disabilities in South Africa
(SAGE Publications, 2013)
The problem of disabilities is growing all over the world. Nevertheless, some progress has been made since the year 1981 was proclaimed International Year of Disabled Persons. In 2001 people living with disabilities accounted ...
HerMES: The far-infrared emission from dust-obscured galaxies
(American Astronomical Society, 2013)
The far-infrared (far-IR) luminosities of luminous infrared
galaxies (LIRGs) and ultra-LIRGs (ULIRGs) are dominated by reprocessed thermal dust
emission, due to a combination of star formation and active
galactic nucleus ...
Herschel-ATLAS: A binary HyLIRG pinpointing a cluster of starbursting protoellipticals
(American Astronomical Society, 2013)
Panchromatic observations of the best candidate hyperluminous infrared galaxies from the widest Herschel
extragalactic imaging survey have led to the discovery of at least four intrinsically luminous z = 2.41 galaxies
across ...
An extensive search for rapid optical variability in ultracool dwarfs
(Oxford University Press, 2013)
In this paper, a summary of optical time-series photometry of 125 ultracool dwarfs is given.
The observing strategy was to monitor each object continuously for 2–3 h in order to ascertain
whether itwas rapidly variable. ...
BDNF Val66Met and DRD2 Taq1A polymorphisms interact to influence PTSD symptom severity: A preliminary investigation in a South African population
(Elsevier, 2013)
BACKGROUND: We evaluated the role that selected variants in serotonin transporter (5-HTT), dopamine receptor 2 (DRD2) and brain-derived neurotrophic factor (BDNF) genes play in PTSD symptom severity in an at-risk population. ...
