  1. A conceptual stocking rate model for the moderately dry mixed and sourveld

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Results for the 1986/87 season from 15 grazing trials situated at five sites were used to develop a qualitative model describing the relationships between stocking rate and herbage mass and between stocking rate and individual animal performance. Although it cannot...
  2. Coping, Occupational Wellbeing and Job Satisfaction of Nurses

    Coping, Occupational Wellbeing and Job Satisfaction of Nurses

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    The study determined the relationship between coping, occupational wellbeing (as measured by burnout and work engagement), and job satisfaction of nurses in two private hospitals in Namibia. A cross-sectional research design was used. One-hundred and ninety-one nurses employed in two...
  3. An end-to-end coupled model ROMS-N<sub>2</sub>P<sub>2</sub>Z<sub>2</sub>D<sub>2</sub>-OSMOSE of the southern Benguela foodweb: parameterisation, calibration and pattern-oriented validation

    An end-to-end coupled model ROMS-N<sub>2</sub>P<sub>2</sub>Z<sub>2</sub>D<sub>2</sub>-OSMOSE of the southern Benguela foodweb: parameterisation, calibration and pattern-oriented validation

    Item type: Journal Article • Journal: African Journal of Marine Science
    In order to better understand ecosystem functioning under simultaneous pressures (e.g. both climate change and fishing pressures), integrated modelling approaches are advocated. We developed an end-to-end model of the southern Benguela ecosystem by coupling the high trophic level model OSMOSE...
  4. Growth models for <em>Pinus patula</em> in Angola

    Growth models for <em>Pinus patula</em> in Angola

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    This study developed growth models for Pinus patula Schiede ex Schltdl. et Cham. for the Central Highlands of Angola for simulating the development of stand characteristics. The model set included dominant height, individual-tree diameter increment, individual-tree height and self-thinning models...
  5. Growth models based on radial increment observations for eight pine species in Angola

    Growth models based on radial increment observations for eight pine species in Angola

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Growth models for the Central Highlands of Angola were developed in this study for Pinus pseudostrobus Lindl., P. kesiya Royle ex Gordon, P. devoniana Lindl., P. chiapensis (Martinez) Andresen, P. elliottii Engelm., P. greggii Engelm. ex Parl., P. montezumae Lamb...
  6. The effect of marine protected areas on an exploited population of sex-changing temperate reef fish: an individual-based model

    The effect of marine protected areas on an exploited population of sex-changing temperate reef fish: an individual-based model

    Item type: Journal Article • Journal: African Journal of Marine Science
    The effect of two marine protected areas (MPAs) on roman Chrysoblephus laticeps (Sparidae), an exploited reef-fish species inhabiting the South African temperate south coast, was simulated with a spatially explicit, individual-based model based on geographically correct habitat distribution. The model...
  7. Does vertical migratory behaviour retain fish larvae onshore in upwelling ecosystems? A modelling study of anchovy in the southern Benguela

    Does vertical migratory behaviour retain fish larvae onshore in upwelling ecosystems? A modelling study of anchovy in the southern Benguela

    Item type: Journal Article • Journal: African Journal of Marine Science
    A spatially explicit individual-based model (IBM) forced by 3D temperature and current fields simulated by a hydrodynamic model of the southern Benguela upwelling region was used to test two hypotheses concerning the role of diel vertical migration (DVM) by Cape...
  8. Predictors of multiple concurrent and multiple sexual partnerships among male and female youth aged 18–24 in South Africa

    Predictors of multiple concurrent and multiple sexual partnerships among male and female youth aged 18–24 in South Africa

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    This study aimed to determine predictors of multiple concurrent and multiple sexual partnerships among South African male and female youth. Data were from a cross-sectional population-based household survey of 3 123 youths aged 18 to 24 years from four South...
  9. Individuals’ feedback trading in market and limit trades: Trading behaviours on the Korean stock market

    Individuals’ feedback trading in market and limit trades: Trading behaviours on the Korean stock market

    Item type: Journal Article • Journal: Investment Analysts Journal
    Using all of individuals’ transactions on the Korean stock exchange from 1999 to 2009, I find that Korean individuals engage in negative feedback trading in market trades and positive feedback trading in limit trades. These patterns are stronger for smaller...
  10. Investor sentiment, asset returns and firm characteristics: Evidence from the Korean Stock Market

    Investor sentiment, asset returns and firm characteristics: Evidence from the Korean Stock Market

    Item type: Journal Article • Journal: Investment Analysts Journal
    This study investigates the effects of investor sentiment on asset returns with respect to firm characteristics. By analysing a unique stock trading dataset of the Korean Stock Market that contains rich information on investor types and sentiment, we confirm that...
