The Archaeology of Regions: From Discrete Analytical Toolkit to Ubiquitous Spatial Perspective

In the 1970s and 1980s, regional analysis was an influential part of archaeological research, providing a discrete set of geographical tools inspired by a processual epistemological and interpretive perspective. With the advent of new technologies, new methods, and new paradigms, archaeological research on regional space has undergone significant changes. This article reviews the state of regional archaeology, beginning with a consideration of its history and a discussion of the fundamental issues facing regional investigations before focusing on developments over the last several years. On one hand, the diversification of archaeological theory has created new paradigms for thinking about human relationships with one another and with the physical environment across regional space; in this regard, historical ecology, landscape archaeology, and evolutionary theory have been particularly influential in recent years. This has led to a corresponding diversification of the traditional methods of regional analysis. Most notably, the advent of powerful digital technologies has introduced new tools, especially those from the geographic information sciences, that build on the quantitative methods of past approaches. The investigation of regional data is no longer based on a discrete toolkit of simple mathematical and graphical procedures for representing spatial relationships. Instead, regional archaeology has matured into a diversity of multiscalar spatial and geostatistical techniques that inform many areas of archaeological inquiry.     

Maps and the settlement of southern Palestine, 1799–1948: an historical/GIS analysis

Historical maps of the Negev Desert which comprises half of the total land area of Palestine can be viewed from several intersecting perspectives relating to aspects such as their contribution to tracing patterns of settlement and agricultural history, imperialism and mapping, and legal geography of land ownership and indigenous people. Here we focus mainly on the first theme, incorporate new methods and demonstrate their application to studies in historical geography.     

Assessing a Computer-aided Instructional Strategy in a World Geography Course

An experiment was conducted to compare student achievement under two differing instructional strategies: a small-group and computer-aided strategy versus lecture instruction. Evaluation was extended in several ways beyond comparison of overall student scores. Results show significant improvements in student achievement produced by the computer-aided strategy with reference to gender, ethnicity and levels of cognitive learning. The study concludes that experimental evaluations of CAI serve best as formative tools to match instructional strategies to specific types of content material and different types of students, and that instructional media are best evaluated along with the instructional method in which they are embedded.     

Identity,contingency and the urban geography of 'race'

Traditional research in urban geography concerned with issues of 'race' has focused on a series of substantively important issues, yet with conceptual foundation inadequate to the task. Specifically, this body of work has employed outdated and theoretically limited conceptions of identity without sufficient consideration to the importance of historical and geographic contingency. I argue in this essay that topics of traditional concern to urban geography gain new relevance and importance when they are reconsidered and reworked from a social constructivist perspective that takes seriously the importance of identity and contingency. I illustrate my argument with discussions of two aspects of my current research agenda. First, I discuss how research on urban residential segregation gains considerably from a more sensitive encounter with multifaceted notions of identity that explicitly address geographic contingency. Second, I review recent empirical research on US mortgage-lending markets that demonstrates the geographic and class contingency of discrimination. The paper ends with a call for research that employs multiple methodologies.     

The Tel Akko Total Archaeology Project (Akko,Israel): Assessing the suitability of multi-scale 3D field recording in archaeology

Abstract

Archaeology is a destructive discipline, and, unfortunately, the majority of methods employed by archaeologists to record and preserve the archaeological record consist of two-dimensional representations of three-dimensional (3D) subjects. Recent breakthroughs in 3D technology, however, have the potential to revolutionize the discipline. In recent years, multiple software suites capable of generating spatially accurate, photorealistic 3D models with a series of digital photographs have become available. Following a successful season of field testing in 2011, the Tel Akko Total Archaeology Project (Akko, Israel) expanded the use of Agisoft’s PhotoScan Pro—one of the commercially available software suites—to test the accuracy and suitability of the program for archaeological applications at multiple scales. After two years of field testing, it is clear that the implementation of PhotoScan Pro in archaeology facilitates unprecedented accuracy in field recording and digital heritage management, and provides a new outlet for the dissemination of archaeological data.     

Spatial–temporal distribution and geographic context of Neolithic cultural sites in the Hanjiang River Basin,Southern Shaanxi,China

Understanding how to live successfully within our environment is among the most pressing challenges facing contemporary society. This paper probes the problem based on comparative analysis and discusses the relationship between the spatial–temporal distribution of the Neolithic cultural sites and the geographic context in the Hanjiang River Basin in the south of Shaanxi Province, China. Archaeological studies have identified 175 Neolithic cultural sites in the study area, with a sequence of Laoguantai (¹⁴C age 8–7 ka BP), Yangshao (¹⁴C age 7–5 ka BP) and the late period of the Neolithic Age (¹⁴C age 5–4 ka BP). The total number of archaeological sites, the distribution area and the density all showed an early ascending and later descending trend, but the proportion of the number of archaeological sites in the study area to the corresponding value of the entire Shaanxi Province declined sharply. Spatially, these sites were concentrated on the terraces of the Hanjiang River and its main tributaries with an altitude of 400–800 m. Multiple data were integrated to clarify the critical effects of tectonic and geomorphologic conditions on the distribution of the Neolithic sites. Further comparisons revealed the correlation of Holocene climate change and environmental evolution with the Neolithic cultural succession in the study area that ameliorated conditions to generally promote the development of the primitive culture while degeneration coincided with the culture's transition or interruption. The discussion on the origin of the primitive culture and the temporal–spatial distribution corresponding to the regional culture differentiation sheds light on the complex and dynamic human–nature interaction system during the Neolithic Age, thus emphasising the wider field-based investigation and high-resolution reconstruction works of the palaeoclimate and palaeoenvironment in the future.     

Modelling Potential Socio-economic Determinants of Building Fires in South East Queensland

This paper investigates the relationships between areas of building fire incidence, levels of socio-economic disadvantage and the underlying socio-economic characteristics in the South East Queensland (SEQ) region, Australia. Disaggregated fire incident data was acquired from the Queensland Fire and Rescue Service (QFRS) and then aggregated to the Statistical Local Area (SLA) level. The Australian Bureau of Statistics (ABS) defined index of socio-economic disadvantage (called ‘SEIFA’) has been used as the basis to identify relationships between socio-economic disadvantage and building fires. A regression model was then developed to predict the incidence of building fires using a range of socio-economic variables. Five significant predictors were identified that include: i) percentage of unemployed, ii) proportion of Indigenous population, iii) families living in separate dwellings, iv) one parent, and v) parent families with children less than fifteen years of age. Results also show that the distribution of building fires varies markedly across the SEQ region, with some of the Brisbane inner suburbs, areas of high socio-economic disadvantage, and parts of inland SEQ associated with relatively high fire rates.     

Partisan sorting in the United States, 1972–2012: New evidence from a dynamic analysis

Whether Americans have “sorted” into politically like-minded counties and to what extent is hotly debated by academic and journalists. This paper examines whether or not geographic sorting has occurred and why it has occurred using a novel, dynamic analysis. Our findings indicate that geographic sorting is on the rise, but that it is a very recent phenomenon. In the 1970s and 1980s, counties tended to become more competitive, but by 1996 a pattern of partisan sorting had emerged and continued through the present. Results suggest this pattern is driven by Southern re-alignment and voting behavior in partisan stronghold counties. Lastly, we find evidence that migration can drive partisan sorting, but only accounts for a small portion of the change.
