Measuring the effectiveness of library instruction poses many challenges, yet is essential to validating the time and energy dedicated to it. Over two years, how subject specific library instruction addressed the needs of the students, the instructor and the librarians was studied. Students were surveyed; librarians analyzed their research paper...
Interannual to decadal variations in Earth global temperature estimates have often been identified with El Nino Southern Oscillation (ENSO) events. However, we show that variability on time scales of 2-15 years in mean annual global land surface temperature anomalies T-avg are more closely correlated with variability in sea surface temperatures...
This study examines the impact of two decades of neoliberal policy reform on food production and household livelihood security in three West African countries. The rice sectors in The Gambia, Côte d’Ivoire, and Mali are scrutinized as well as cotton and its relationship to sorghum production in Mali. Although market...
The solid solutions of chlorapatite compounds Ba₅Mn₃−[subscript]xV[subscript]xO₁₂Cl (x = 0–3.0) and Ba₅Mn₃−[subscript]xP[subscript]xO₁₂Cl (x = 0–3.0) have been synthesized through solid state reactions and Pechini or sol–gel method using citric acid. The colors of the samples change from white (x = 3.0) through turquoise (x = 1.5) to dark green (x...
Suspected thifensulfuron resistant spiny annual sow-thistle was identified near Colfax, Washington, in two fields with a winter wheat and lentil rotation. Therefore, studies were conducted to examine resistance of spiny annual sow-thistle to thifensulfuron and cross-resistance to other acetolactate synthase inhibitors and to determine the physiological and molecular basis for...
Headwater riparian areas occupy a large proportion of the land base in Pacific Northwest forests, and thus are ecologically and economically important. Although a primary goal of management along small headwater streams is the protection of aquatic resources, streamside habitat also is important for many terrestrial wildlife species. However, mechanisms...
The species composition, distribution and concentration of ichthyoplankton off the central Oregon coast in the NE Pacific Ocean were examined during 2000 and 2002 to investigate annual, seasonal, vertical, and cross-shelf variability. Larval concentrations were also analyzed in relation to water temperature and salinity. The 281 samples collected from 5...
How and where the ocean tides dissipate
their energy are longstanding questions with both
oceanographic and astronomical implications. Two
decades ago, Doake suggested that flexing of Antarctic
ice shelves by the underlying ocean tide is an important
energy sink, perhaps accounting for over half the global
dissipation rate. Observational constraints...
Tidal energy dissipation is estimated for eight semi‐diurnal and diurnal constituents using a global inverse solution constrained by TOPEX/Poseidon altimeter data. Very similar spatial patterns are obtained for all semi‐diurnal constituents, with about one third of the total dissipation occurring in the deep ocean over rough topography. Maps for diurnal...
