This article proposes a new four-phase chronology for Postclassic and colonial occupation at Xaltocan, Mexico, using Bayesian statistical modeling of a suite of 54 radiometric dates. Of these, 46 samples come from recent extensive excavations of sealed, stratified household deposits, facilitating improved understanding of sample context and resulting in a more accurate chronology. The timing of the adoption of major ceramic wares at the site and intrasite level is outlined and contextualized within broad, regional phases. These results are particularly valuable given recent research that repudiates a uniform chronological framework for the Basin of Mexico in the Postclassic period, and indicates instead a significant amount of chronological overlap and regional variation in the use of distinct ceramic types.

AbstractThe construction chronology of three of the earliest Dunhuang Mogao Grottoes (Caves 268, 272, and 275) has been the subject of ongoing debate for over half a century. This chronology is a crucial topic in terms of further understanding of the establishment of the Dunhuang Mogao Grottoes, early Buddhism in the Gansu corridor, and its relationship with Buddhism developed in the Central Plains. Building upon archaeological, art historical and radiocarbon (14C) dating studies, we integrate new 14C data with these previously published findings utilizing Bayesian statistical modeling to improve the chronological resolution of this issue. Thus, we determine that all three of these caves were constructed around AD 410–440, suggesting coeval rather than sequential construction.

Abstract Why is the #MeToo movement very active in some countries but not in others? What factors encourage the transnational diffusion of digital feminist activism? Although transnational forces are important, we argue that domestic political opportunity structures play a more significant role than transnational influences in the country-level diffusion of #MeToo. We collected 35,211 global tweets and used Bayesian statistical modeling to test the implications of our theory. Our findings support the idea that as a country better protects its citizens’ political and civil rights and civil liberties, individuals in that country are more likely to engage in the #MeToo movement.

Provincial Capital

We use a provincial perspective combined with compositional and stylistic data and historic accounts to propose three provincial strategies for imperial interactions—bolstering, resistance, and emulation—and note a fourth, exodus. A sample of three Late Postclassic period (A.D. 1350–1521) pottery types differs in chemical composition between two localities in south-central Veracruz, Mexico. Sherds from the Aztec provincial capital of Cuetlaxtlan along the lower Cotaxtla River are compared to those from the Lower Blanco River where Callejón del Horno is located. The composition of stamped-base bowls, Texcoco Molded censers, and Aztec III-style Black-on-orange bowls is distinct in samples from the two localities, with only scant evidence of exchange. A few vessels of Aztec III Black-on-orange were imported from the Basin of Mexico to Cuetlaxtlan. The stylistic characteristics on Aztec III-style Black-on-orange vessels do not distinguish the two Veracruz localities, but there are differences between them and illustrated vessels from the Basin of Mexico. The Cuetlaxtlan province was subject to unusual imperial investments, which may account partly for the emulation of imperial styles. Despite documentary evidence of rebellions, another factor was local decisions to use a prestigious exogenous style.
