The Paisley Caves in Oregon record the oldest directly dated human remains (DNA) in the Western Hemisphere. More than 100 high-precision radiocarbon dates show that deposits containing artifacts and coprolites ranging in age from 12,450 to 2295 ¹⁴C years ago are well stratified. Western Stemmed projectile points were recovered in...
The Delton Silent Reading Test, Forms A and B, was
developed as an alternate test for the Schonell Silent Reading
Test which is currently used for screening the reading
comprehension of special students. The aim of the Delton
Silent Reading Test is to achieve greater consistency in mid-year
and mid-program...
Preservice teachers' beliefs and values develop due to their long "apprenticeship of observation" (Lortie, 1975) and often filter their teacher education experiences (Feiman-Nemser & Buchman, 1986; Pajares, 1992). Case methods may be one curricular tool by which to instill change in preservice teachers' beliefs and values. This study investigated the...

Although plant remains, such as opal phytolith and charcoal analyses, have been used since the beginning of the 20th century to reconstruct past environments by ecologists and botanists, only recently have these techniques been considered by archaeologists in understanding the past at the site level. This study employs opal phytolith...
Parasites are ubiquitous members of ecological communities, capable of contributing to the decline of vulnerable populations. Therefore, monitoring parasite level is a critical component for host management. Molecular tools, such as quantitative polymerase chain reaction (qPCR), can be valuable additions to monitoring protocols that assess parasitic disease risk to hosts....
Multiple factors are known to influence student success in higher education. Barriers to postsecondary success for underrepresented STEM students are numerous and well documented. We detail an exploratory study of STEM faculty notions of successful students and the instructional practices they employ to cultivate student success. We use a conceptual...
The Younger Dryas climatic event is a global phenomenon associated with a 1,000 year return to glacial conditions during the late Pleistocene period between 12,800 and 11,500 cal BP. Because of its significant effects on paleoenvironmental conditions in some parts of the world, archaeologists commonly seek to assess whether the...
