Jordan has a higher fertility rate (3.8) than the averages of countries similar in income to Jordan (2.2) and compared to the Middle East and North Africa region as a whole (2.8) (WHO, WB, UNICEF, & DHS, 2011). The findings of the 2009 Jordanian Population and Family Health Survey demonstrated...
Karl Jordan (1861-1959) was an extraordinarily productive entomologist who influenced the development of systematics, entomology, and naturalists' theoretical framework as well as their practice. He has been a figure in existing accounts of the naturalist tradition between 1890 and 1940 that have defended the relative contribution of naturalists to the...
Although the public schools have spent billions of dollars on computer
technology, only a few teachers are integrating them into their teaching. The
purpose of this study was to determine barriers to the integration of computers into
teaching and potential teaching strategies to encourage integration. Teachers (N=122) from 14 elementary...
Put generally, the work I have conducted in my time at Oregon State University has been to answer two questions. The first of these is “Why do I get this particular product from this particular chemical reaction?” and the second is “How do the reagents in this chemical reaction lead...
Large silicic magmatic systems are responsible for producing the largest explosive volcanic eruptions on earth. These phenomena, although infrequent (i.e., 1 per 100,000 years), impact the global climate, deposit ash over continent sized regions, and significantly alter landscapes. Silicic magmatism also plays important roles in the formation and ongoing evolution...
The High Lava Plains province (HLP) of southeastern Oregon is a Miocene to Recent volcanic upland characterized by widespread basaltic volcanism and west-migrating rhyolitic volcanism. New ⁴⁰Ar/³⁹Ar ages for HLP rhyolites demonstrate that the trend of migrating rhyolitic volcanism is robust, reflecting westward migration at a rate of -35 km/m.y....
The United States Department of Energy has identified the pebble-bed reactor as a high priority for US research with the end goal of licensing a pebble-bed reactor (PBR) for operation in the United States. Before this can be accomplished significant research must be done regarding the safety of the pebble-bed...
The purpose of this study was to gather and interpret data in
order to contribute to a better understanding of older employed women
as they prepare for the transition from the paid workforce to
retirement.
Selected descriptive variables were measured to determine
their relationship to retirement readiness in a sample...
The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...
