Identifying Narrative Descriptions in Agent-Based Models Representing Past Human-Environment Interactions

There is a growing use of bottom-up simulation models to reconstruct past human-environment interactions. Such detailed representations pose difficult questions not only in their design (the generality-realism trade-off) but also about the inferences that are made from them. The historical sciences are faced with seeking to make robust inferences from limited, potentially biased and/or incomplete samples from uncontrolled systems, and as a result have sometimes employed narrative explanation. By contrast, simulation models can be used experimentally and can generate large amounts of data. Here, using an agent-based model of hunter-gatherer foraging in a previously unexplored ecosystem, we consider how narratives might be identified from the trajectories produced by simulations. We show how machine learning methods can isolate qualitatively similar types of model behaviour based on summaries of model outcomes and time series. We stand to learn from this approach because it enables us to answer two questions: (i) under what conditions (representations and/or parameterisations) do we observe in the model what is recorded in the archaeological and/or palaeoenvironmental record? and (ii) does the model yield unobserved dynamics? If so, are they plausible? Using models to develop narratives is a logical extension of the bottom-up approach inherent in agent-based modelling and has the potential, alongside conventional methods of model evaluation, to aid in learning from the rich dynamics of such simulations.     

Use of Bronze Celts in Military Operations

The purpose of this article is to bring together archaeological evidence relating to the consumption of porpoises from excavations at both Dover and Canterbury. A contrast can be drawn between porpoise remains recovered from Anglo-Norman fishermen in Dover and contemporary remains from two sites within the Cathedral Precincts at Canterbury. These differences are then considered in relation to issues of status.     

考古学视野下的礼仪甄别方法及其反思

后过程主义考古的兴起促进了考古学家对礼仪问题的关注,礼仪研究的首要步骤是对相关考古遗存进行有效的甄别。目前学界使用较多的甄别方法是根据礼仪独特的礼仪成分和逻辑结构,从形形色色的考古遗存中甄别出与礼仪相关的遗存。以商代为例,用这种方法可以有效地甄别出占卜、葬仪、祭祀等礼仪遗存。然而,在甄别的实践中依然存在一些无法克服的困难。考古学家在进行礼仪研究的同时,也应理性地认识到这些缺陷。

Using Enthesis Robusticity to Infer Activity in the Past: A Review

In bioarchaeological studies, entheseal change is commonly used to infer patterns of activity in past populations. This category of skeletal modification includes both pathological changes (enthesopathies) and changes in size, shape and surface complexity (robusticity). Despite the recent impetus to reassess the use of enthesopathies as markers of activity, robusticity has received little critical attention. In this review, we reassess key assumptions that underpin the use of robusticity in activity studies, drawing on anatomical, physiological, biomechanical and sports medicine literature sources. We find that, whilst there is some evidence to support the assumption that variation in enthesis robusticity reflects different activity patterns, little is known about the process through which this variation is produced. Presently, the stimuli (dynamics of muscle use or muscle size) for entheseal adaptation are ill-defined, a situation that limits our interpretive abilities. Consideration of bone functional adaptation principles and of the relationship of entheses to soft tissue also highlights how other factors, such as age, sex and genetic background, may influence enthesis robusticity and obscure activity-related adaptation. Understanding how these factors influence enthesis robusticity helps define how robusticity studies should be controlled, but further research is required to clarify how these factors interact with activity in robusticity development and the precise relationship between activity and robusticity. Ultimately, this review emphasises the complexity of entheseal structures and their morphological development. Any interpretation of activity from enthesis robusticity should be approached with caution, but in some circumstances, the endeavour may be ill-advised.

Ancient Egypt in Brazil: A Theoretical Approach to Contemporary Uses of the Past

In this paper we consider archaeology as a product of social interaction, and discuss how ancient Egyptian materiality has been an important part of identity building in Brazil. We begin by reviewing our theoretical setting, and suggest that a postmodern approach is most helpful to our goal of understanding the social context of the public uses of archaeology. The paper then turns to the trajectory of “Egyptomania” in Brazil, from the 19th century onwards, highlighting the importance of cultural movements such as Kardecism and Masonry in this trend. We argue that the use of Egyptian subjects in Brazil has connections with social inequality, racism, and gender biases. Finally, we present a case study on positive recent trends in the presentation of ancient Egypt in school textbooks which highlights critical approaches to the use of ancient Egyptian subjects in contemporary Brazil.     

A Preamble to Family Policy: Issues of the Past and Present

The subject of family appears appropriately related to social policy, since family functions interface with society so closely. Moreover, U.S. families have been changing rapidly enough in this decade to warrant new attention to policy development. Public and political interest in family policy has been growing. Yet, historical barriers to government targeting family issues for policy development abound. While some intellectual, organizational, and bureaucratic mobilization has occurred, producing broad family policy declarations, interest groups are in the process of positioning themselves differentially, and disagreement about the value of explicit family policy is on the increase. The author believes that family policy will develop slowly in the D.S., and that comprehensive and cohesive family policy can better be considered a goal rather than a readily implemented public activity.

Fieldwork Methodology in South American Maritime Archaeology: A Critical Review

In archaeology, data obtained from the analysis of material evidence (i.e., the archaeological record) from extensive excavations have been a significant means for the ultimate development of interpretations about human life in the past. Therefore, the methodological procedures and tools employed during fieldwork are of crucial importance due to their effect on the information likely to be recovered. In the case of maritime archaeology, the development of rigorous methods and techniques allowed for reaching outcomes as solid as those from the work performed on land. These improvements constituted one of the principal supports—if not, the most important pillar—for its acceptance as a scientific field of study. Over time, the growing diversity of sites under study (e.g., shipwrecks, ports, dockyards, and prehistoric settlements) and the underwater environments encountered made it clear that there was a need for the application of specific methodological criteria, in accordance with the particularities of the sites and of each study (e.g., the research aims and the available resources). This article presents some ideas concerning the methodologies used in South American investigations that have exhibited a strong emphasis on the analysis of historical shipwrecks (the sixteenth to twentieth centuries). Based on a state-of-the-knowledge review of these research projects, in particular where excavations were conducted, the article focuses on the details of the main strategies adopted and results achieved. The ideas proposed in this article can be useful as a starting point for future activities of surveying, recording, and excavating shipwrecks.     

A Usable Past: History and the Politics of National Identity in Late Victorian England

For the past two decades, issues of English national identity have provided a fertile field for historical investigation. In the late Victorian era, the development of professional standards of scholarship within the academy gave a new dimension to historical debates. The bitter quarrels about appropriate research techniques from the 1860s to the 1890s, among James Anthony Froude, Edward Freeman and John Horace Round, acted as a proxy for the vision of national identity that each historian espoused. After 1870, the development of a national narrative focused on constitutional history as its primary vehicle. The battle over historical reconstruction represented a surrogate for divergent views about political values and national identity. What sometimes seemed frivolous scholarly skirmishes, therefore, had a much greater political importance. As a result, the long feud had greater importance than the eccentric personalities of the participants appeared to indicate. For Froude, the Tudor age of discovery and religious reformation represented the best of English character. For Freeman, a strong Gladstonian Liberal, consensus and continuity over many centuries defined English history best. John Horace Round, a Conservative stalwart, thought that Freeman had slanted his historical conclusions to validate his Liberal politics and reinterpreted the Norman conquest to express his own political beliefs. Thus the quibbles about shield walls and other issues provided a terrain for the real cause of antagonism: different views of national identity that history furnished. Each historian constructed a usable past in order to justify contemporary discussions of national identity.     

Identifying Chemical Activity Residues on Prehistoric House Floors: A Methodology And Rationale For Multi‐Elemental Characterization of a Mild Acid Extract of Anthropogenic Sediments

Archaeologists have employed sediment chemistry in site prospection for nearly a century. For example, phosphorus is a good indicator of human occupation, because it is a generic indicator of human activity. Recently, multi‐element studies of sediments have successfully identified specific activity areas by analysing other elements in addition to phosphorus. To reach its full potential, however, sediment chemistry must be undertaken with an understanding of how these residues are formed and of the chemical indicators that can be used to identify specific activities. Methodologies that optimize the extraction of specific residues must be employed. Not to do so is a naïve application of the technique.     

Ethnoarchaeology: A Non Historical Science of Reference Necessary for Interpreting the Past

Ethnoarchaeology appears nowadays as a poorly formulated field. However, it could become a real science of reference for interpreting the past if it was focused upon well-founded cross-cultural correlates, linking material culture with static and dynamic phenomena. For this purpose, such correlates have to be studied in terms of explanatory mechanisms. Cross-cultural correlates correspond to those regularities where explanatory mechanisms invoke universals. These universals can be studied by reference to the theories found in the different disciplines they relate to and which are situated outside of the domain of archaeology. In the domain of technology, cross-cultural correlates cover a wide range of static and dynamic phenomena. They allow the archaeologist to interpret archaeological facts—for which there is not necessarily analogue—in terms of local historical scenario as well as cultural evolution. In this respect, it is shown that ethnoarchaeology, when following appropriate methodologies and focussing on the universals that underlie the diversity of archaeological facts, does provide the reference data needed to climb up in the pyramid of inferences that make up our interpretative constructs.
