Spatial autocorrelation tests and the Classic Maya collapse: Methods and inferences

Spatial autocorrelation, resulting in pattern or structure in geographically distributed data, is discussed in theoretical and practical terms. Tests for spatial autocorrelation are presented, along with an explication of the relationship between autocorrelation models, the product-moment correlation coefficient and the spatial autocorrelation test statistic. Two archaeological examples illustrate the application of the auto-correlation test statistic. The first uses a hypothetical data set, which shows the type of map patterns that appear with various levels of spatial autocorrelation, and the second examines the terminal distribution of long-count-dated monuments at lowland Classic Maya sites. The results of the second example fail to support arguments for simple patterning in the cessation of the erection of these monuments and, by inference, in the Maya collapse itself. Finally, it is argued that while the identification of spatial autocorrelation is often the goal of spatial analyses, the presence of autocorrelation violates the assumptions of certain statistics used in such analyses.     

American Historical Demography: A Review Essay

Abstract

American historians of modern art routinely assume that after World War II New York replaced Paris as the center of the western art world. An analysis of the illustrations in French textbooks shows that French art scholars disagree: they rate Jean Dubuffet as the most important painter of the era, ahead of Jackson Pollock, and they consider Yves Klein's anthropometries of 1960 as the greatest contribution of a single year, in front of Andy Warhol's innovations in Pop Art. Yet the French texts also show that the French artists' practices and conceptions of art paralleled those of the Americans. Thus, whereas French and American scholars disagree over the relative importance of their nations' artists, there is no disagreement that the most important art of the 1950s was produced by experimental seekers, and that of the 1960s by conceptual finders.     

Worldwide cross-cultural studies and their relevance for archaeology

Archaeological inference based on ethnographic analogy may or may not be correct. What is worse, there is no systematic way to tell. With certain provisos, it is better to generate archaeological inference from the results of worldwide cross-cultural tests of relational hypotheses. Such tests may provide more benefits than within-region comparisons. This paper discusses a number of ways in which worldwide cross-cultural research may be used in archaeological inference, including: generalizing about societal types, inferring from presumed causes, inferring from material correlates, and inferring from noncausal associations. The paper concludes with a discussion of how comparative archaeology could help cross-cultural researchers test causal theories diachronically.     

Policy of Delay: Evidence from a Bayesian Analysis of Metropolitan Land‐Use Choices

Do local policymakers strategically use delay in permitting development to forestall the growth machine? The mantras of smart growth and sustainable development assume local governments can balance the competing values of economic development, ecology, and equity interests in a community. We employ a political market framework to explain differences in local government land use decisions. This framework conceptualizes policy choices as resulting from the interplay between the aggregate policy demand by residents, developers, and environmental interests and the aggregate supply by government authorities. Delays can be imposed strategically through processes of development approval by city governments where industry strength and form of government vary within county‐level service‐delivery fragmentation. We utilize novel Bayesian multilevel modelling of data collected from 2007 and 2015 surveys of Florida city planners and find strong institutional effects and multilevel relationships.     

Comparing expeditious procedures for the seismic vulnerability assessment on the European territorial context: reliability,feasibility, cost,and time consumption

ABSTRACT

The definition of strategies for the preservation and protection of cultural heritage is a topical issue, especially in view of the increasing relevance of the theme of seismic risk mitigation and reduction.

The prediction of the impact an earthquake could have on existing buildings requires the knowledge of their dynamic behaviour. The procedure to be adopted for this purpose is quite complex and onerous in terms of costs, time, and implementation, especially when the study concerns territorial areas rather than single buildings. The definition of methodologies aimed at respecting the principles of economic sustainability and preserving human life and architectural heritage is of paramount importance to assess seismic vulnerability using available resources. Rapid methods for the seismic vulnerability assessment, aimed at defining buildings vulnerability and intervention priority lists, must be implemented to guarantee the preservation of historical centers.

This article describes the application to some case studies of different methods aimed at creating fragility curves for the vulnerability assessment on the European territorial context. The comparison between a deterministic approach and a new probabilistic one is performed for all case studies, to define the most suitable methodology in terms of reliability and savings in cost and time.
