Intra-site Spatial Analysis in Ethnoarchaeology

ABSTRACT

The interpretative power of quantitative intra-site spatial analysis has long been recognised by archaeologists. On the contrary, very few ethnoarchaeological works have engaged with the statistical analysis of intra-site pattern of artefacts and ecofacts. Nonetheless, ethnoarchaeology is uniquely placed to guide and assist in the identification of sound techniques and in the development of the methodology of analysis. The possibility to directly connect the distribution of the proxies under study with the activity that generated such distribution, provide the means of fine-tuning the tools we use for identifying these patterns in the archaeological record. As a consequence, archaeological methodology and interpretation both benefit from the application of improved methodologies. In this paper we review some of the most common techniques used to analyse activity areas and we provide examples of the application of such techniques to ethnoarchaeological contexts. The aim is to assess how archaeology can benefit from the intra-site spatial analysis of ethnoarchaeological contexts.     

A third road to the past? Historical scholarship in the age of big data

Is a third passage to the past possible, beyond Elton's and Fogel's two roads of narrative history and scientific/quantitative history? One that would combine narrative history's focus on the event, on individuals and their actions, at a particular time and place, to scientific/quantitative history's emphasis on explicit behavioral models based on social-science theories? That is the question this article addresses. It illustrates a computer-assisted methodology for the study of narrative—quantitative narrative analysis (QNA)—that does just that. Based on the 5 Ws + H of narrative—Who, What, When, Where, Why, and How—QNA quantifies events without losing the event itself, without losing people behind numbers, diachronic time behind synchronic statistical coefficients. When used in conjunction with dynamic and interactive data visualization tools (and new natural language processing tools), QNA may provide a third unforeseen road to the past.     

Modeling the prehistoric arrival of the sweet potato in Polynesia

The sweet potato is a plant native to the Americas, and its pre-historic presence in Polynesia is a long-standing anthropological problem. Here we use computer-driven drift simulations to model the trajectories of vessels and seed pods departing from a segment of coast between Mexico and Chile. The experiments demonstrate that accidental drift voyages could have been the mechanism responsible for the pre-historic introduction of the sweet potato from the Americas to Polynesia. While present results do not relate to the feasibility of a transfer by purposeful navigation, they do indicate that this type of voyaging is not required in order to explain the introduction of the crop into Polynesia. The relatively high probability of occurrence and relatively short crossing times of trips from Northern Chile and Peru into the Marquesas, Tuamotu and Society groups are in agreement with the general consensus that this region encompasses the area of original arrival and subsequent dispersal of the sweet potato in Polynesia.     

Modeling the effect of mandatory district compactness on partisan gerrymanders

Geographic compactness standards have been offered as neutral and effective standards constraining redistricting. In this paper, we test this allegation. Redistricting is treated as a combinatoric optimization problem that is constrained by compactness rules. Computer models are used to analyze the results of applying compactness standards when political groups are geographically concentrated. Several population models are used to generate populations of voters, and arbitrary plans are created with combinatoric optimization algorithms. We find that compactness standards can be used to limit gerrymandering, but only if such standards require severe compactness. Compactness standards are not politically neutral—a geographically concentrated minority party will be affected by compactness standards much differently than a party supported by a geographically diffuse population. The particular effects of compactness standards depend on the institutional mechanism that creates districts.     

Collaboration as feminist strategy

I discuss my collaboration with Susan Hanson, which spanned a decade, culminating in our book, Gender, Work and Space. I focus on the productivity of our research collaboration. It led us to combine quantitative and qualitative methodologies, and economic geography and feminist cultural theory, in ways that allowed us to find an audience amongst, not only feminist geographers but also non-feminist political economists and planners. Our collaboration involved a large number of research assistants as well, and though this kind of collaboration is typically hidden in most research accounts, these research assistants were active producers of survey data. I consider this, as well as how they helped us to localize and situate our knowledge claims. Finally, I highlight the support that comes from a feminist collaboration.     

Using multivariate statistics and fuzzy logic system to analyse settlement preferences in lowland areas of the temperate zone: an example from the Polish Lowlands

The influence of relief, as well as other environmental features such as soils or the hydrological regime, on prehistoric settlement patterns is commonly accepted. Settlement patterns and preferences changed over time in different areas, so it is difficult to formulate general rules of human behaviour throughout history. In lowland areas of the temperate zone, which lack radical relief changes and have widespread access to water resources, specific settlement preferences and significant changes in these preferences are difficult to interpret.New methods developed to address the problem of the settlement transformations as a result of prehistoric settlement and economic processes using multivariate statistics have been adapted for the middle part of the Great Poland Lowland. In this region, data from the Polish Archaeological Record Project database have been used.Models of the dependence between geomorphological features and settlement intensity form the basis for estimating changes in prehistoric settlements. The degree of preference (or avoidance) is a nonparametric function of the number of archaeological sites observed in the area relative to the number of sites expected from a completely random pattern. The most crucial factors for settlement are distance to plateau edges, distance to water bodies, and the wetness index. The results show that the entire investigated area is more or less suitable for settlement, but the most occupied terrains are the areas near plateau edges.     

Environmental Education in Russian Universities

This paper presents the results of a simulation exercise designed to explore and understand the implications of trying to survive in a marginal and poverty-stricken African community. The aim of the simulation was to create an approximation of a community involved in an income-generating project, akin to a Public Works Programme. This project sought to enable every person to earn a dollar a day on which to live. In addition, the exercise helped the participants to question and assess whether the Millennium Development Goals (MDGs) have a chance of reaching their proposed targets. The nearly one hundred participants were undergraduate geography students, reading Development Studies and Demography at Rhodes University in Grahamstown, South Africa. The outcome of the simulation was that the students developed a clearer understanding of poverty, particularly the ‘Deprivation Trap’, and how complex the development process is in practice.     

David Warren Sabean. Landbesitz und Gesellschaft am Vorabend des Bauernkriegs: Eine Studie der sozialen Verhältnisse im südlichen Oberschwaben in den Jahren vor 1525

In conventional approaches to computer analysis of historical sources, one must represent the data in structured formats in which content and context are discarded. Extensible markup language (XML), developed for data transfer on the Internet, permits preservation of the full text of irregular historical sources without sacrificing the ability to conduct systematic analysis. Related querying tools offer most functions of a relational database management system, including data transformation facilities for coding, standardizing, and aggregating nominal data. An XML database permits multiple interpretations of the data because the unit of analysis and the coding schemes are not defined at entry. In a case study of probate inventories, the author demonstrates how structured analysis of domestic interiors can be performed and introduces approaches to studying semistructured data.     

Ecological Regression and the Analysis of Voter Behavior

Abstract

The project now underway to produce a new, multi-volume print and online edition of Brian Mitchell's British Historical Statistics is an opportunity to examine the history of the celebrated work. An account of its conception, reception, and evolution provides a window through which to examine a central aspect of economic history's disciplinary history and methodenstreit; certain fundamentals relating to the demand for, and supply of, historical statistics; and to introduce the British Historical Statistics Project, which is now underway but still in its infancy, during which it is closely examining its antecedents in order to learn the correct lessons from that history.
