Stephen Pinker and the long peace: alliance,deterrence and decline

It is now widely accepted, at least among academic students of war, that there has been a great and generally benign transformation in the character of war. The sort of big wars involving the world's greatest powers, those that in practice or in prospect dominated international affairs from the rise of Napoleon to the collapse of communism, are now considered to be essentially obsolescent. But to what extent is that really true?     

Walking a Fine Scientific Line: The Extraordinary Deeds of Dutch Neuroscientist C. U. Ariëns Kappers Before and During World War II

Dutch neuroscientist Cornelius Ubbo Ariëns Kappers is famous for pioneering neuroembryological work and for establishing the Amsterdam Central Institute for Brain Research. Less well known is his anthropological work, which ultimately played a role in saving Dutch Jews from deportation to their deaths during the Holocaust. Ariëns Kappers extensively campaigned against anti-Semitism and Nazi persecution during the 1930s. During World War II, he utilized his credentials to help create anthropological reports “proving” full-Jews were “actually” partial- or non-Jews to evade Nazi criteria, and at least 300 Jews were thus saved by Ariëns Kappers and colleagues. His earlier work demonstrating differences between Ashkenazic and Sephardic Jewish skull indices became the focus of an attempt to save hundreds of Dutch Portuguese Jews collectively from deportation. Ariëns Kappers and colleagues brilliantly understood how anthropology and neuroscience could be utilized to make a difference and to save lives during a tragic era.     

An inter-site comparison of enamel hypoplasia in bison: implications for paleoecology and modeling Late Plains Archaic subsistence

Bison bison mandibular molars from the Late Plains Archaic kill/butchery sites of Buffalo Creek (Wyoming) and Kaplan-Hoover (Colorado) exhibit significant frequencies of dental enamel hypoplasia (DEH), a defect believed to reflect information about physiological status of individual animals. This study provides a methodology to estimate the ontogenetic and seasonal timing of DEH formation in bison dentition. Integration of these estimates with data from bison life history and grassland ecology allows inferences on age- and season-specific factors exacerbating periodic physiological declines that were recorded in the form of enamel hypoplasias. Differences between assemblages indicate regional variability in grassland conditions, with data from Buffalo Creek pointing to recurrent drought that reduced forage capacity and contributed to physiological stress in bison over two consecutive years. Seasons of physiological stress reflected in the DEH correspond to each of the three kill events at the locality, suggesting that predictability of bison behavior in this location was a critical factor in influencing the seasonal timing and location of repeated hunting episodes. Unlike Buffalo Creek, timings of stress episodes are not consistent with season of death in the Kaplan-Hoover bison assemblage, suggesting that favorable grassland conditions were the primary factor influencing timing of this large single-kill event in order to provision for the upcoming winter. DEH analysis represents a developing approach in the construction of models addressing key aspects of local grassland and bison ecology as well as offers unique insights into the hunting strategies and subsistence decisions of Late Plains Archaic foragers.     

Norman crusaders in the Catalan reconquest: Robert Burdet and the principality of Tarragona, 1129-55

A Norman adventurer, Robert Burdet, while participating in the Reconquista, established a short-lived crusader principality at Tarragona. This Norman gained fame after 1114, first serving Alfonso I el Batallador (‘The Warrior’) of Aragón in the wars against the Banu Hūd of Zaragoza; thereafter he was contracted by Archbishop Oleguer Bonestruga of Tarragona, the primate of northeastern Spain after 1118 and a papal legate after 1123, to assume in 1129 the secular lordship of Tarragona which had been constituted by the comital house of Barcelona as a papal fief and ecclesiastical principality. After this prelate's death in 1137, the Norman held this frontier and attempted to found an autonomous crusader state, but in 1146 the new archbishop, Bernard Tort, began to re-impose ecclesiastical control over Tarragona. At the same time, the house of Barcelona inherited the royal title from Aragón, thus forming the crown of Aragón by merging the former kingdom with the Catalan counties and reviving the crusade against Muslim Lérida and Tortosa which fell in 1148 and 1149. The archbishop and count moved against the Normans to integrate their principality into the new Aragó-Catalan federation. Prince Robert lost much of his power before his death in 1155, and his heirs were reduced to vassalage to Barcelona and subservience to their ecclesiastical lord, the archbishop of Tarragona. Civil war broke out after 1155 and the expulsion of the Normans by 1177 brought their principality to an end.
