ABSTRACT Pesticide use is an important component of agricultural and non-agricultural pest control in tropical areas. However, the fate of pesticides in tropical soils is not as well understood as that for soils from temperate regions. Tropical soils defy easy generalizations, but they are typically very old soils characterized by year-round uniformity of temperature regime. Although only a few studies have directly compared pesticide fate in tropical and temperate soils, there is no evidence that pesticides degrade more slowly under tropical conditions. Laboratory studies in which soils have been held under standardized conditions reveal that pesticide degradation rate and pathway are comparable between tropical and temperate soils. However. field investigations of tropical pesticide soil fate indicate that dissipation occurs more rapidly, in some cases much more rapidly, than for pesticides used under similar temperate conditions. The most prominent mechanisms for this acceleration in pesticide dissipation appear to be related to the effect of tropical climates, and would include increased volatility and enhanced chemical and microbial degradation rates on an annualized basis.

The name of the ACH, the Association for Computers and the Humanities, is something of a conundrum for 21st-century practitioners in ���humanities computing���. The juxtaposition it proposes���the coordinate ���and���, the resistant thingness of ���computers������suggests little of the range of research interests that motivate the ACH community, nor does it give a clue of what might bind them together in a common organization. Perhaps the vagueness of the rubric was lucky, in view of the astonishing and unpredictable proliferation of computers and ...

In 2002, at the annual joint meeting of the Association for Literary and Linguistic Computing and the Association for Computers and the Humanities in T��bingen, Germany, the executive councils of ACH and ALLC established a joint work group charged with examining possibilities for closer collaboration between the two organizations and within the field of digital humanities more widely. The Text Encoding Initiative Consortium also appointed representatives to monitor the discussion. That group has been referring to itself as the ...
