(University of Missouri--Columbia, 2009)
for Fagus grandifolia pollen, in conjunction with supporting DNA evidence, indicates consistent patterns of more northerly refugial locations and different migration routes for Fagus grandifolia than currently accepted. Patterns of pollen deposition and DNA...
Three essays on trade gravity model
(University of Missouri--Columbia, 2009)
an entirely new data set that extends the data from Rauch and Trindade (2002) on ethnic Chinese networks to a panel of about 40 years. We find that Chinese networks have a generally strong and robust influence on trade. We find weak evidence that language...
Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in four representative...
Socialization activities and professional competencies within a graduate social work program
(University of Missouri--Columbia, 2010)
standard for social work programs who are accredited by the Council on Social Work Education. To this end, the construction of a competency-based assessment instrument of four identified practice behaviors was pursued. Second to the construction...
Felix convivum : platters and transformations of dining behavior in the Roman world
(University of Missouri--Columbia, 2009)
the iconographical, literary sources and archaeological material reflect actual dining practices during the Roman period. In this thesis, I will examine the presence, or absence, in the archaeological record of large-sized platters in conjunction...
The effects of prompts-based argumentation scaffolds on peer-led interactive argumentation
(University of Missouri--Columbia, 2009)
The main focus of this study was to determine whether prompts-based argumentation scaffolds (PAS) would result in improvement of students' argumentation in a peer-led argumentation context. The study also examined the effects of PAS on students...
