The aim of the research was to determine if, using histological methods, it w ...
  3. Efficient Bayesian analysis of spatial occupancy models
    Bleki, Zolisa, 2020-12-30T10:18:00Z, University of Cape Town
    Species conservation initiatives play an important role in ecological studies. Occupancy models have been a useful tool for ecologists to make inference about species distribution and occurrence. Bayesian methodology is a popular framework used to model the relationship between species and environme ...
  4. Exploring the adoption rationales and effects of off-grid renewable energy access for African youth: a case study from Tanzania
