Anomalous areas and awkward ages: alleviating concerns

Anomalous radiocarbon ages for foraminifera shells

[1] The causes for discordant radiocarbon results on multiple species of planktonic foraminifera from highsedimentation-rate marine sediments are investigated. We have documented two causes for these anomalous results. One is the addition of secondary radiocarbon for which we have, to date, only one firm example. It involves an opal-rich sediment. The other is the incorporation of reworked mate...

Uncertainties on the Luminescence Ages and Anomalous Fading

It is well known that some minerals give underestimated luminescence ages due to anomalous fading. The anomalous fading follows a logarithmic decay law characterized by its slope, the socalled fading rate or g-value. Using the fading rate, Huntley and Lamothe (2001) suggested some correction for the fading underestimation of young samples (<40-50 ka). For polymineral fine grains, we observe a f...

Alleviating the concerns with the SDT approach to reasoning: reply to Singmann and Kellen (2014)

In their comment on our article (Trippas et al., 2014a), Singmann and Kellen (2014; henceforth SK) suggest that our use of signal detection theory (SDT) provides an uninformative characterization of the data, that our application of SDT to causal-conditional reasoning is unnecessary and misguided, and that the model does not provide a good fit of the data. We will address each of these points. ...

Mobilization Forum: Awkward Movements

Several years ago, Gay Seidman complained in an article in Mobilization that scholars of the South African antiapartheid movement had so ignored the role of armed struggle as to leave the impression that the movement and its most famous leader, Nelson Mandela, were nonviolent in the Gandhian mold. In fact, Mandela was the first military commander of the African National Congress. He owed his po...
