Human biology in the Classic Maya collapse: Evidence from paleopathology and paleodiet

We review evidence from human biology—paleopathological and isotopic paleodietary studies on ancient Maya skeletons—to assess the validity of ecological models of the Classic Maya collapse, in which elevated disease and deteriorating diet are commonly assumed. To be upheld, the health arguments of ecological models require that the Maya disease burden (1) was greater than that for many other societies and (2) increased over the span of occupation. The dietary argument requires (1) consistent change in diet from Preclassic and Early Classic Periods to the Terminal Classic and (2) increasing social divergence in diet. A correlation between diet and disease is necessary to link these arguments. Neither pathology nor isotopic data consistently support these criteria. Instead, it appears that local environmental and political factors created diversity in both disease burden and diet. In view of the human biological data, we are skeptical of ecological models as generalized explanations for the abandonment of Classic Maya sites in the southern lowlands.     

Dynamic Central Place Theory: Results of a Simulation Approach

A dynamic central place theory is formulated as a simulation model in which retail activities, described by cost equations, and consumers, described by spatial interaction equations, interact to generate a central place system. The behavior of the model is then examined. Simulation results show that the basic character of the system—whether it is agglomerated or dispersed—depends primarily on a single parameter in the interaction equation, and only secondarily on the specification of the cost function. The results are highly robust in that they are largely independent of the initial sizes and locations of centers, and even independent of the type of interaction equation used. The patterns generated appear plausible.     

Performing a different narrative: museum theater and the memory-work of producing and managing slavery heritage at southern plantation museums

In the southeastern United States, operators of plantation museums have traditionally engaged in a selective and romanticised remembrance of the antebellum past that has regrettably silenced and marginalised the historical experiences and struggles of enslaved African people. More recently, some plantation managers have sought to engage in the ‘memory-work’ using artistic practices to reconstruct and interpret slavery heritage for visitors. Our study explores museum theatre as a form of memory-work and suggests that theatrical performances of the memories of enslavement are an increasingly important but not yet fully understood strategy for recovering, embodying, and representing a different and hopefully more just narrative about enslaved Africans. We visit three plantation museums where managers hosted a theatrical performance of enslaved oral histories and explore the motivations and experiences of managers and the director of the slave performance. Realising the power and efficacy of theatrical performance as memory-work practice requires understanding how the management of the interpretation process can be difficult. We delve into the emotion-laden challenges confronting slavery-related museum theatre development at the North Carolina plantations and discuss the creative response formulated at the sites to help visitors work through unexpected feelings and understandings about the past.     

Standardisation in 3D Geometric Morphometrics: Ethics,Ownership, and Methods

The collection and analysis of 3D digital data is a rapidly growing field in archaeology, anthropology, and forensics. Even though the 3D scanning of human remains in archaeology has been conducted for over 10 years, it is still frequently considered as a new field. Despite this, the availability of 3D scanning equipment and the number of studies employing these methods are increasing rapidly, and it is arguably damaging to the validity of this field to continue to consider these methods new and therefore not subject to the same standardisations as other researches. This paper considers the current issues regarding the lack of standardisation in the methods, ethics, and ownership of 3D digital data with a focus on human remains research. The aim of this paper is to stimulate further research and discussion, allowing this field to develop, improving the quality and value of future research.
