4 pp. / Southwest forests are complex systems that are influenced by climate variability. Wildfires naturally occur in these forests and woodlands, but with an increasing population, land management decisions are becoming more difficult. This publication is a result of discussions from the "Workshop on Climate Variability and Ecosystem Impacts" that was sponsored by UA Cooperative Extension in February 2005. It provides a summary of the current situation, a summary of climate change science for land management, and a brief description of suggested future research in climate science as it relates to forests and woodlands.

This dissertation reports on an analysis conducted to establish the electronic research needs experienced by postgraduate students at higher education institutions within an increasing electronic research environment. Innovation and improvements in technology have caused research students to approach the library with a whole range of needs and expectations undreamed of in the nonelectronic library. A quantitative research instrument was mainly used to gather data, together with the results from a user survey. This study is therefore regarded as a quantitative study. From both the literature survey and research for this study it became clear that postgraduate students in South Africa and throughout the world experience similar e-research needs with regard to primary data sharing, transfer of data and computation, e-access, e-communication, e-training and e-publishing. By taking the specific needs of postgraduate students into account, the library will be able to create an electronic research environment distinguished by ease of use and access - the principal and most valued research partner in a postgraduate students’ pursuit of academic distinction and success. / Dissertation (M.Ed (Computer-integrated Education))--University of Pretoria, 2007. / Curriculum Studies / unrestricted

This article reviews the effectiveness of dose forms and the efficacy of dosage and distribution in morphosyntax intervention for children. Dose forms include the commonly used techniques, procedures, and intervention contexts that constitute teaching episodes; dosage includes the quantitative measures of dose, dose frequency, total intervention duration, and cumulative intervention intensity (S. F. Warren, M. E. Fey, & P. J. Yoder, 2007). Based on the literature, this article first outlines and evaluates the range of dose forms and intervention contexts that clinicians and researchers can employ to facilitate morphosyntactic acquisition. Then, it defines and evaluates research outcomes and provides examples of the dosage components. Current evidence, which focuses primarily on young children and early-developing morphology and sentence structures, suggests that some dose forms and dosage levels are more effective with some populations and some morphosyntactic forms than with others. Distributed practice within sessions and throughout the total period of treatment appears to be more facilitative than massed practice, at least for children with typical language development. The scant research concerning total intervention duration suggests that it affects children's developmental trajectory and that treatment attendance matters. What is missing from the research base is detailed information about the effectiveness and efficacy of intervention for the acquisition of particular morphosyntactic forms in specific populations. The article summarizes these gaps in 3 research goals that reflect the argument of S. F. Warren et al. that it is time to conduct systematic comparisons of specific dose forms while testing how each measure of dosage affects outcomes.
