The first stage of reform resulted in the introduction of Independent Power Producers (IPPs) and Small Power Producers (SPPs) programs. This was followed by, in the mid-to-late 1990s, a proposal to introduce a market-oriented reform. This reform program envisaged the separation of generation from transmission and distribution functions; introduction of competition in generation; development of new market-oriented regulatory arrangements, and the privatization of the industry. This reform, argued its proponents, will improve the efficiency of the electricity industry; lower electricity tariffs; improve quality of service; draw private investment into power generation sector; reduce the government¿s investment burden of financing expensive electricity infrastructure and hence enhance its capacity for investing in other priority programs such as health, education and other social activities. This paper examines the veracity of these arguments. This examination is assisted by a historical review of the evolution of the Thai Electricity Supply Industry (ESI). This review reveals that the above noted arguments are unsupportable on the basis of the technological, economic, environmental, social and political realities prevalent in Thailand. This paper further emphasizes the need to clearly identify the `real¿ rationale for reform so that an appropriate reform pathway ¿ consonant with socio-political contexts in Thailand ¿ could be selected. 2008-01-01T00:00:00Z http://hdl.handle.net/10453/8580 Effects of chlorpyrifos on macroinvertebrate communities in coastal stream mesocosms Colville Anne; Jones Peter; Pablo Fleur; Krassoi Rick; Hose Grant; Lim Richard This study measured the effects of a single pulse of chlorpyrifos at nominal concentrations of 1 and 10 mu g/l on the macroinvertebrate community structure of a coastal stream mesocosm system. Analysis of data using Principal Response Curves (PRC) and Monte Carlo tests showed significant changes in the treated stream mesocosms relative to that of the controls. These changes in the macroinvertebrate assemblages occurred within 6 h, and persisted for at least 124 days after dosing. Significant community-level effects were detected at the lowest concentration on days 2 and 16 post-dosing, giving a no-observed effect concentration (NOECcommunity) of 1.2 mu g/l (measured). The mayflies Atalophlebia sp. and Koorrnonga sp., Chironomidae and Acarina were all sensitive to chlorpyrifos and decreased in abundance in treated mesocosms after dosing. The fauna of these coastal stream mesocosms showed similar sensitivity to chlorpyrifos with that of other reported studies, but there was no evidence of recovery after 124 days. 2008-01-01T00:00:00Z http://hdl.handle.net/10453/8577 Long term trends of stand transpiration in a remnant forest during wet and dry years Macinnis-Ng Catriona; Yunusa Isa; Eamus Derek; Zeppel Melanie; Whitley Rhys Daily and annual rates of stand transpiration in a drought year and a non-drought year are compared in order to understand the adaptive responses of a remnant woodland to drought and predict the effect of land use change.
