Cardillo, Marcelo Abstract: Through phylogenetic reconstruction this work analyzes the diversification of lanceolate points of the South Central Andes which began in the early Holocene and spanned the entire mid- Holocene. Based on a regional-scale data, we discuss the links between the increasing mid-Holocene risk conditions, the patterns of diversification of point lineages, demographic change and animal resources consumption. We distinguish a first instance of greater diversity of points, a higher rate of innovation and less class longevity. These trends progressively stabilized, giving rise to a pattern of less innovation, decreasing taxa diversity and greater class longevity as well as an age-related extinction pattern. We show that as projectile points diversified,hunting efficiency increased along the mid-Holocene by the increased representation of high-return fauna in the regional zooarchaeological record. We suggest that this diversification... PubDate: Sun, 1 Jan 2023 00:00:00 +0000

Zhdanov, Andrew Abstract: This article analyzes the hierarchy of factors in the development of crisis trends in a consolidated democracy using the example of the United States of America. The authors assess the surge of political instability in the United States, which led to the deconsolidation of the liberal democracy regime, through the prism of centrifugal processes within the American elite and the erosion of democratic institutions over the past 30 years. The main problem of the study is the contradiction between the crisis of democratic regimes in the countries of the Euro-Atlantic region and the high indicators of the factors of the consolidation of democracy, according to classical political science theories. The authors use the path analysis method to determine the main path and hierarchy of factors of erosion of the liberal democracy regime in the United States, which is an example of the "old" democracy and, according to traditional political science, is the most protected from destructive...

Authors:Hall; Mark E Abstract: While McLaughlin et. al. (2018) argue for similar trends in the medieval Irish historical record and the archaeological radiocarbon record, part of their results are due to an ad-hoc bandwidth being used to calculate the kernel density estimates (KDEs). This contribution looks at using a data-driven bandwidth to re-calculate the KDEs and also look at the first derivative of the KDEs. The results here indicate the radiocarbon record declines much sooner than the early 9th Century and not recovering again until the late 11th Century. Comments are also noted on the Irish annals and the approach, for at least one region, on the use of radiocarbon dating. PubDate: Sat, 1 Jan 2022 00:00:00 +0000
