    Mashiane, K.K. (Katlego); Ramoelo, Abel; Adelabu, Samuel (Springer, 2023-03)
    Ecological research has focused on the importance of environmental factors on spatial biodiversity variations and organisation. This is important because of scant conservation resources. We used stepwise backward selection ...
  • Do crime generators exist in a developing context? An exploratory study in the township of Khayelitsha, South Africa 
    Breetzke, Gregory Dennis; Edelstein, Ian S. (Springer, 2022-03)
    Crime generators are places that increase the risk of crime occurring due mainly to the fact that they attract a large number of motivated offenders and suitable targets to a particular location. Research identifying crime ...
  • Do locals benefit from being in the ‘tourist capital’? Views from Livingstone, Zambia

    This study used 268 household and 13 key informant interviews to get the views of Livingstone city residents on economic, environmental and sociocultural effects of tourism on local households and the city. Results show ...
  • Does crime count? Investigating the association between neighbourhood-level crime and recidivism in high-risk parolees 
    Breetzke, Gregory Dennis; Polaschek, Devon L.L.; Curtis-Ham, Sophie J. (Elsevier, 2019-01)
    The neighbourhood contexts in which former offenders live following their release from prison has been relatively neglected in recidivism studies. Moreover, the relationship between neighbourhood-level crime and parolee ...
  • Downstream development during ridging South Atlantic Ocean anticyclones 
    Ndarana, Thando; Lekoloane, Lesetja E.; Rammopo, Tsholanang S.; Reason, Chris J.C.; Chikoore, Hector; Engelbrecht, Francois A. (Springer, 2023-09)
    Ridging South Atlantic high pressure systems (ridging highs) are often accompanied by cut-off low (COL) pressure systems aloft, but may also occur without them, in which case a linear baroclinic wave would be observed ...
  • Drivers for sun protection in Black South Africans 
    Diffey, Brian; Wallace, Melissa; Mistri, Preethi; Wernecke, Bianca; Wright, Caradee Yael (Wiley, 2020-07)
    Sun protection behavior studies are almost exclusively carried out in populations with fair skin for the obvious reason that people with unpigmented skin are more susceptible to the health impacts of excess solar ultraviolet ...
