This study examined some demographic and psychological predictors of teachers' commitment in Lagos State, Nigeria. The specific objectives of the study were to ascertain if teachers' perceived organizational justice will significantly affect their levels of commitment to the schools; establish the nature of relationships that exists between gender, types of schools and teachers' levels of commitment. In order to achieve these objectives, 200 participants from 16 secondary schools in Lagos State (M=103; F=97) were randomly selected to respond to the Organizational Justice Scale (OJS) and Organizational Commitment Scale (OCS). The data collected were analyzed using correlation, independent t-test and regression analysis and the results showed that there is a significant positive relationship between perceived organizational justice and teachers' commitment; female teachers reported a significantly higher level of commitment than their male counterparts, public school teachers were more committed than private school teachers. It was also revealed that gender, types of schools and organizational justice jointly accounted for sixty-

The Snowmelt Runoff Model (SRM) was used to simulate timing and magnitude of runoff for six climate scenarios (2030 and 2080 ‘Wet’, ‘Middle’, and ‘Dry’). The water supply results from SRM were run through a Southern Idaho reservoir operation and water rights allocation model (MODSIM). The 2030-Dry and 2080-Dry scenarios produce supply deficits relative to the current climate of 5.4%, and 1.9%, respectively, for which the corresponding irrigation water delivery reductions were 1.7% and 2.7%. In contrast, the 2030-Wet, 2030-Mid, 2080-Wet, and 2080-Mid climate change scenarios increased water supply by 13.4%, 0.5%, 19.5%, and 5%, respectively, for which water deliveries increased by 0.41%, 0.04%, 0.34% and 0.14%, respectively. Idaho's irrigation delivery and storage system can ameliorate the risk of dry climate change, but is incapable of storing and delivering the increased water supplied by the wet climate change scenarios. This is an opportunity worth exploring.

Fire is a major disturbance that causes rangeland change. In this study, we compared the turbulent fluxes of carbon dioxide and sensible and latent heat, measured over burned and unburned sites of a sagebrush-dominated mountain in southern Idaho during the late summer of 2006. The outcome of the investigation shows that fire altered the horizontal components of turbulence intensity (i u and i v ) as well as the partitioning of radiant energy between latent and sensible heat fluxes. Average daytime Bowen ratios (b) at the burned and unburned sites were 2.03 and 1.87. On the basis of Bowen ratios determined from eddy covariance measurements of sensible and latent heat fluxes, the sensible heat fluxes were relatively more significant at the burned site than at the unburned site most of the time, and the converse was true of the latent heat fluxes. The exception to this was for the few days following heavy rainfall, when near-surface soil moisture increased the evapotranspiration at the burned site more than at the unburned site until the shallow moisture supply was depleted. By means of ratios of CO 2 /(H + LE), fluxes, carbon sequestration was found to be more significant at the unburned site, declining at both sites as summer progressed but declining more rapidly at the burned site than at the unburned site.
