The chronology and regional context of late prehistoric incised arrowheads in southeastern Arabia

The typology, distribution and chronology of incised arrowheads is examined. A lower chronology than has hitherto been suggested for their occurrence is then argued. Evidence from other areas is used to illustrate the point that the examples from southeastern Arabia are unique and are chronologically unrelated to other ancient west Asian examples.     

Managing the risk of climatic variability in late prehistoric northern Chile

The concept of risk management encompasses the diverse strategies employed in preventing and mitigating losses associated with social and environmental calamities. Building on the growing literature on risk, we use archaeological data from the Tarapacá Valley, located in northern Chile, to document the risk-reduction tactics mobilized by the valley’s inhabitants to navigate the increasingly volatile environmental and social conditions of the Late Intermediate Period (AD 1000–1450). With the onset of exceptionally unpredictable environmental conditions after AD 1100, residents of the Tarapacá Valley chose strategies such as increased trade and agricultural diversification and extensification to minimize shortages in staple resources. Threats of raiding and intra-community strife exacerbated the risks associated with subsistence shortfalls. Valley communities elected a number of strategies to curtail conflict-induced risk, including movement of settlements and field systems to defensible locations, construction of walls and other defensive features, and the introduction of plazas. Rock art data suggest that trade was increasingly embedded in ritually sanctioned events involving groups from different ecological zones. While studies of risk have focused disproportionately on environmental hazards, subsistence-related crises are often compounded by social hazards that require their own risk-mitigating strategies, further constraining options for coping with subsistence stress.     

Monongahela subsistence-settlement change: The late prehistoric period in the lower Upper Ohio River valley

The Late Prehistoric period in the lower Upper Ohio River basin of southwestern Pennsylvania and adjacent portions of Maryland, Ohio, and West Virginia is dominated by a material-culture assemblage named Monongahela. Monongahela has been associated with subsistence-settlement systems that included a large number of upland villages that were often far removed from large river valleys. The existence of these villages has been explained as resulting from intra- and interregional warfare. While these upland villages may have obtained as a result of warfare, it is argued that they served as important links in regional divided risk strategies in response to local environmental and social risks.     

Toward an archaeology of late prehistoric Eskimo bands in coastal northwest Alaska

The methodology of analogical explanation of prehistoric Eskimo remains in northwest Alaska is examined. The sociospatial organization of Wales or, Kingigan, settlement and the greater Kingikmiut territory is evaluated as an example based on ethnohistorical studies and archaeological excavations carried out at three sites in the locality since 1926, and relationships between the archaeological material and historic socio-spatial divisions of Kingigan are explored. The review reveals that only two historic family compound locations have been sampled archaeologically, and that several others have not yet been sampled. However, existing samples nevertheless represent the larger Agianamiut, Kiatanamiut and Kurigitavik districts in the settlement, ca. AD 1800–1850 and extending back to prehistoric times from ca. AD 1000. A nomenclature for socio-spatial units is proposed that includes compound families, local bands, tribal capitals and tribes based on examples of historic Eskimo territorial organization. Caution is suggested in applying the nomenclature to prehistoric cultures in cases where continuity of artifact forms, art styles and motifs with historic local cultures are not demonstrable. Application of historic Eskimo analogues to prehistoric entities such as Birnirk and Punuk cultural remains risk fallacious interpretations because continuity with historic examples are not demonstrable and alternative explanations cannot be eliminated.     

Dietary patterns during the late prehistoric/historic period in Cikobia island (Fiji): insights from stable isotopes and dental pathologies

The dietary patterns of eight adults and one child interred in the Korotuku burial mound (Cikobia, northern Fiji), dated from the late prehistoric/historic period (around AD 1850), have been investigated using carbon and nitrogen stable isotope signatures and dental and oral pathologies. Bone collagen isotopic compositions showed that (1) males and females had similar diets in terms of terrestrial C₃ resources and marine fish components and proportions; (2) the proportion of marine fish comprised around 25% of the protein fraction of the diet, and the proportion of vegetal food was high; and (3) one canid that was also studied had a different diet, probably rich in shellfish. Oral and dental examinations of the humans evidenced (1) a low level of dental macrowear, (2) a high rate of carious lesions—interproximal and cervical—of about 15%, and (3) a low amount of abscessing, as well as the presence of alveolar bone recession and calculus in most of the adults. This evidence suggests a diet relying mainly on vegetal food with very limited shellfish consumption. When viewed in the light of ethnohistoric information, this pattern suggests a particular sociocultural behaviour, including food selection, since the analyses of the canid remains indicate that more diversified food resources were available than those consumed by the humans. Overall observations suggest that the deceased in the Korotuku burial mound might be members of an elite living on the island, thus pointing to possible social stratification in the late prehistoric/historic Cikobia community.     

A note on the use of temporal frequency distributions in studies of prehistoric demography

Temporal frequency distributions of archaeological sites and radiocarbon dates are commonly used as proxies for prehistoric population levels based on the assumption that more people create a stronger archaeological signal. While this assumption is certainly correct, we question whether relative frequencies of sites or dates observed from prehistoric contexts are necessarily linked to human demography. In this paper, we demonstrate that the typical positive curvilinear frequency distributions observed in archaeological contexts also regularly occur in paleontological and geological contexts and are thus likely caused by the operation of time-dependent destructive processes, what we call “taphonomic bias.” Using a simple model, which assumes a constant rate of site loss over time, we show how taphonomic bias can produce positive curvilinear frequency distributions through time even in cases of population stasis, decline, and fluctuation. We conclude that caution must be used when attempting to infer demographic trends from frequency distributions alone.     

The settlement patterns of north-eastern and south-eastern Arabia in late antiquity

The east Arabian settlements in antiquity were never large urban sites. However, they were the main centres of the communities that inhabited that area, interfacing between the nomadic and sedentary societies. A study of the distribution and characteristics of these sites reveals different, complementary functions. They were organized in local networks forming the essential structure of the settlement pattern and delineating the territories of communities having their own political identity.

Two cases of facial involvement in probable treponemal infection from late prehistoric coastal North Carolina

This paper describes two late prehistoric burials from coastal North Carolina with cranial and postcranial lesions characteristic of treponemal infection. Each case exhibits facial lesions consistent with clinical reports of treponemal infection, but which have not previously been documented in these populations. The suite of facial lesions in one case and a mandibular lesion in the other serve to illustrate the variability inherent in treponemal infections. © 1998 John Wiley & Sons, Ltd.     

The late prehistoric Cahokia cultural system of the Mississippi River valley: Foundations,florescence, and fragmentation

The development, florescence, and subsequent demise of an organizationally complex cultural system in the American Bottom, part of the central Mississippi River valley, spanned a little over half a millennium. Cahokia, the largest Precolumbian site in the United States, is located within this segment of fertile floodplain, as are many other subsidiary settlements that varied greatly in terms of their size, internal structure, and occupational histories. Numerous projects over the past 30 years have resulted in the rapid accumulation of considerable information and divergent interpretations about the nature of the societies represented archaeologically by a series of superimposed settlement systems.     

New patterns in the locational choice of immigrants in Spain

During recent years, Spain has experienced an important revolution in its migration flows. With the 2008–2013 Spanish financial crisis, the model of economic growth that attracted a large number of foreign people disappeared, and the entry of immigrants for reasons other than economic issues gained relevance. Linked with this phenomenon are the new patterns of locational choice across provinces and the variation in the nature of immigrants. In this paper, we examine the differential patterns and drivers of immigration across Spanish regions before and after the financial crisis. Special attention is paid to the question of how the characteristics of individual migrants influence their locational preferences. To answer this question, we use the Dirichlet multinomial regression model. The results obtained show a sharp change in the locational patterns of Spanish immigrants after the economic recession, confirming that traditional economic incentives are less relevant, while non-economic factors linked with a better lifestyle gain importance. They also reveal that, regardless of the economic conditions, network effects are strong. Finally, and what is probably more important for us, our estimates support the hypothesis that the locational preferences rely on the interaction between the immigrants’ characteristics and the underlying locational features.     

Non-destructive fabric analysis of prehistoric pottery using high-resolution X-ray microtomography: a pilot study on the late Mesolithic to Neolithic site Hamburg-Boberg

The characterisation of prehistoric pottery fragments presents a quite complex task. In provenance studies, petrographic and chemical analyses of the ceramic materials are employed to investigate potential production areas in respect to the geolocial background. Moreover, also the production technology of the firing process, as well as the forming techniques used by the prehistoric potters are of great interest. Their investigation is most often accompanied by a destructive preparation of the samples. In this paper, we want to present high-resolution X-ray microtomography (μ-CT), a non-destructive and non-invasive method, as a supplementary research tool in the study of prehistoric pottery.     

Pervasiveness of phytoliths in prehistoric southwestern diet and implications for regional and temporal trends for dental microwear

Our previous analysis of phytolith content of coprolites showed that calcium oxalate phytoliths from desert food plants caused dental microwear among prehistoric Texas hunter-gatherers. We demonstrated that phytoliths from desert succulents were ubiquitous and abundant in hunter-gatherer coprolites. We found that calcium oxalate phytoliths were harder than human dental enamel. We concluded that phytoliths from desert succulent plants caused dental microwear and hypothesized that such dental microwear would be common in other desert hunter-gatherer and horticultural peoples. Presented here are further analyses of phytoliths from coprolites. Two additional hunter-gatherer sites and three Ancestral Pueblo (Anasazi) horticultural sites are included in this study. Calcium oxalate phytoliths are ubiquitous in coprolites from hunter-gatherer sites in the Mojave Desert and the Colorado Plateau. For the three Ancestral Pueblo sites, calcium oxalate phytoliths from desert succulents (agave family and cactus family) are the most common types of phytoliths encountered. However, silica phytoliths are also present in Ancestral Pueblo coprolites. The data demonstrate that phytoliths from non-cultivated desert plants were a source of dental microwear for the pre-maize Archaic hunter-gatherer bands and maize-reliant Ancestral Pueblo villages.     

Local employment growth patterns and the Great Recession: The case of Spain

The 2008 financial and economic crisis has led to widespread destruction of employment in Spain. Using municipality data, I examine employment growth differences between urban cores, urban hinterlands, and rural areas during the pre‐crisis period and the recession period. The data show that patterns of growth and decline have been very uneven across different types of areas. While in the boom years, hinterlands and rural areas experienced higher growth, urban core areas have done better during the recession years. I then test three strands of explanations for local growth differences: (i) the role of the local sectoral composition, (ii) the role of human capital, and (iii) the role of access to urban core areas. Estimations for employment growth in the two periods show that the crisis has altered some of the drivers of local employment growth and that human capital has been a key determinant of local resilience during the Great Recession.     

Changing models of settlement,economy, and ritual activity: Recent research in late prehistoric central Europe

Recent research in central Europe is changing our understanding of the role of centers in economic and social systems of late prehistoric times. Increased attention to smaller, more typical settlements shows that they engaged in economic activities similar to those at the large, fortified complexes. Abundant new evidence pertaining to ritual activity indicates that ritual was often integrated into daily life at settlements. The evidence from the exceptionally rich data on late prehistoric central Europe can be of substantial value for developing models applicable to contexts in other parts of the world.     

The history of method and theory in the study of prehistoric puebloan pottery style in the American Southwest

The history of Americanist archaeology can be profitably approached through an examination of ceramic design studies in the puebloan region of the American Southwest. An intellectual tradition is represented throughout these studies, grounded in the assumption that ceramic design variation can be reflected, among other things, in prehistoric social groupings. Within this tradition, a number of differences in method, theory, and application can be distinguished, including (1) the classificatory systems employed, (2) the spatial and temporal scales at which ceramic design variation was studied, and (3) the potential functional role of stylistic attributes on pottery. The debates, both intellectual and social, surrounding the development of method and theory in the New Archaeology are clarified by this historical review, as are the transitions to Culture History and from the New Archaeology in the American Southwest.     

The changing structure of a city: temporal changes in cubic spline urban density patterns

"Using the basic summary of urban structure given by the population density function, this paper estimates changes which have occurred in the structure of the Detroit [Michigan] metropolitan area during the past two decades. Both overall density changes and direction-specific changes are estimated using census data and the method of cubic spline regression. The results give more revealing insight into the structural changes which have occurred in the city than has been possible with traditional models of urban population density."     

The role of labrid fish in prehistoric economics in New Zealand

Labrids are one of the most common types of fish to occur in inshore rocky marine habitats in New Zealand. There are major discontinuities in their relative abundance in archaeological sites from different regions of New Zealand, and these are difficult to reconcile with known distributional patterns. A number of possible explanations are examined such as changes in fishing technology and various ecological factors. It is concluded that the reasons for these observed fluctuations may vary considerably from one case to another, but where large numbers were caught by prehistoric people who had access to alternative fish resources, unreliability of some major aspect of the economy may be inferred. A combination of poor sea conditions and marginal horticulture is likely to increase the importance of labrid fish.     

Spatial‐temporal patterns of snow cover in western Canada

Snow cover is often measured as snow‐water equivalent (SWE), which refers to the amount of water stored in a snow pack that would be available upon melting. Snow cover and SWE represent a source of local snow‐melt release, and are sensitive to regional and global atmospheric circulation, and changes in climate. Monitoring SWE using satellite‐based passive microwave radiometry has provided nearly three decades of continuous data for North America. The availability of spatially and temporally extensive SWE data enables a better understanding of the nature of space‐time trends in snow cover, changes in these trends and linking these trends to underlying landscape and terrain characteristics. To address these interests, we quantify the spatial pattern of SWE by applying a local measure of spatial autocorrelation to 25 years of mean February SWE derived from passive microwave retrievals. Using a method for characterizing the temporal trends in the spatial pattern of SWE, temporal trends and variability in spatial autocorrelation are quantified. Results indicate that within the Canadian Prairies, extreme values of SWE are becoming more spatially coherent, with potential impacts on water availability, and hazards such as flooding. These results also highlight the need for Canadian ecological management units that consider winter conditions.
