An inferred burial and exhumation history of Pennsylvanian strata in the central Appalachian foreland basin is constrained by integrating palaeothermometers, geochronometers and estimated palaeogeothermal gradients.Vitrinite re£ectance data and £uid inclusion homogenization temperatures indicate that burial ofLower andUpperPennsylvanian strata of theAppalachianPlateau inWest Virginia exceeded 4...

Fraser fir (Abics frmeri (Pursh) Poir.) is an endemic species consisting of six major disjunct populations in the Appalachian Mountains, U.S.A. Nuclear DNA content was measured with laser flow cytometry to determine if genome size differences could be detected among the disjunct populations of Fraser fir and its close relatives, balsam fir (Abies bnlsamea (L.) Mill.) and Canaan fir (A. balsamea...

Zircon age peaks at 2100–1650 and 1200–1000 Ma correlate with craton collisions in the growth of supercontinents Nuna and Rodinia, respectively, with a time interval between collisions mostly <50 Myr (range 0–250 Myr). Collisional orogens are two types: those with subduction durations <500 Myr and those ≥500 Myr. The latter group comprises orogens with long-lived accretionary stages between Nun...

Publications signal a professor’s productivity and may lead to raids by other universities. Professors attach different values to non-wage benefits at a raiding university, and will quit only if benefits elsewhere are relatively high. The social value of these benefits means research may increase welfare even without a direct social value from research. Other results are: welfare would be reduc...

Tobacco use is increasingly prevalent among vulnerable populations, such as people living in rural Appalachian communities. Owing to limited access to a reliable internet service in such settings, there is no widespread adoption of electronic data capture tools for conducting community-based research. By integrating the REDCap data collection application with a custom synchronization tool, the ...
