Since the early 1990s, the town of Mandeville has become a haven for returning residents (henceforth returnees), particularly Jamaicans who migrated to England in the 1950s and 1960s and subsequently returned to Jamaica in the 1990s to retire (See Nettleford 1998). As Harry Goulbourne (1999, 164) observes, “...The hill town of Mandeville has acquired the reputation of being a desirous destinati...

We present techniques for realistic real-time rendering of complex landscapes that consist of many highly detailed plant models. The plants are approximated by dynamically changing sets of billboards. Realistic illumination is approximated using spherical harmonics. Since even the rendering of simple billboard cloud plants is too time consuming, the landscape in the background is approximated w...

These soils are young and not much developed or stratified into horizons. Accumulation of humus will be visible, indicating that the soils are already sinks for carbon dioxide. An adverse characteristic of soils tipped in the last 30 to 40 years is s...
