Boards and Cords: Discriminating Types of Artificial Cranial Deformation in Prehispanic South Central Andean Populations

For over a century, a number of ambiguous typologies have been employed to distinctly categorise types of artificial cranial deformation. This paper provides a quantitative method, based on multiple dimensions and discriminant function analysis, by which to assign skulls not only into discrete categories: deformed or not, but also by type: annular or tabular. A series of prehispanic, adult, human crania (n = 469) from archaeological sites in Argentina, Bolivia, Chile and Peru represented by both normal and artificially deformed specimens, provide craniometric data for four measurements across the vault: maximum cranial length, breadth and height and the frontal chord. These data are used to develop three indices which in turn are used to compute two discriminant functions. Results are plotted on a territorial map whereby the type of deformity can be determined. When these methods were applied to a comparative cranial sample of nondeformed skulls from South America, 100% of the samples was found to be nondeformed. When these methods were applied to the samples which were subjectively classified a priori by the first author as nondeformed, 81.3% of the samples were found to be nondeformed. This study demonstrates the value of a more objective and quantitative method by which to classify artificial cranial deformation, and thus provides a new approach.

Effects of artificial deformation on cranial morphogenesis in the south central Andes

One of the most interesting issues of the interface between biology and culture is the artificial deformation of the skull. This modification is produced during early morphogenesis through the use of devices that alter the normal growth and development, to obtain a culturally established model. This paper, using a large cranial sample from the South Central Andes (1586 individuals), describes and documents a detailed morphometric study of the changes affecting the vault, cranial base, face, orbits and nasal region resulting from the tabular erect (TE), tabular oblique (TO), circular erect (CE) and circular oblique (CO) deformations with respect to the model without deformation. Data from 17 metric variables were processed by a one‐way ANOVA and LSD test for paired comparisons. All of the deformation types produce significant morphometric divergence in most of the anatomical structures of the skull. The TE exhibits: a restriction of antero‐posterior growth producing expansion in cranial width and height, frontal flattening, shortening of the face and cranial base, widening of the face, increased nasal and orbit height (ORH) and a foramen magnum size increase. The TO exhibits: most change reflected in the widening of the cranial vault, shortening of the cranial base and face, frontal flattening, increased nasal and ORH and foramen magnum size decrease. The CE style exhibits: a decrease in cranial width and strong increase in the cranial height, a reduction in frontal width, expansion of the cranial base and face, increased nasal and ORH, orbital widening and a foramen magnum size increase. The CO style exhibits: a decrease of the cranial vault's width and height, expansion along its length, stretching of the cranial base and face, reduced frontal width, fronto‐malar and biorbitary elongation of the face and further development of foramen magnum.

Sinus and meningeal vessel pattern changes induced by artificial cranial deformation: A pilot study

This study explores the changes in sinus and meningeal vessel patterns caused by various types of artificial cranial deformation. Endocranial casts were prepared from six crania exhibiting one of three types of deformation (lambdoid, parallelo-fronto-occipital and fronto-vertico-occipital), as well as from 15 undeformed crania. Vessel and sulcus patterns of each cranium were analysed and these patterns included depth of impressions, size and number of vessels, and directional pathways of vessels. Comparisons were made within and between the different deformation types. The results indicated that deformation has an effect upon the pattern, shape and depth of vessel impressions. Vessels tended to be flattened in the areas directly affected by cranial deformation, and there was often compensatory enlargement of other vessels. Further, three of the six artificially deformed crania exhibited enlarged occipital/marginal sinuses, suggesting that this trait is developmentally plastic and greatly influenced by environmental factors.     

Evidence of artificial cranial deformation from the later prehistory of the Acacus Mts. (southwestern Libya,Central Sahara)

The 1999–2001 Italian–Libyan Archaeological Mission in the Acacus and Messak, southwestern Libya, resulted in the discovery of human specimens from the Wadi Tanezzuft Valley belonging to the Final Pastoral horizon (i.e. late Neolithic, about 3000 years bp). Some of these show clear traces of artificial cranial deformation. This practice, hitherto unrecorded in the central Sahara, is described and analysed in this paper. It represents an additional source of information about population movements and cultural connections in the area. It does not appear to be gender‐related, and neither does it involve all individuals in the sample, suggesting some kind of social and/or cultural differentiation within the group. The pattern of cranial deformation described here is not directly related to types most commonly encountered among recent African populations and elsewhere. It may be considered a combination of antero‐posterior and circumferential deformation and thus is referred to as a ‘pseudo‐circular type’. Archaeological and ethnographic literature related to Africa and southwestern Asia is investigated in order to identify a possible origin of such a custom and its pattern of diffusion. The evidence, according to other sources of information, contributes to interpret this area at the centre of the Sahara as a focal point of population movements and circulation of cultural traditions across North Africa in the latest phases of the Pastoral Neolithic.

Re‐examining the relationship between cranial deformation and extra‐sutural bone formation

The relationship between cranial deformation and the occurrence of extra‐sutural bones remains poorly understood. Scholars are divided about whether or not cranial deformation causes an increased occurrence of these bones, and even those who agree that deformation does have an influence often disagree about which locations on the crania are most impacted. Part of this issue clearly stems from the difficulties in finding appropriate samples from which to test the hypothesis that deformation leads to an increased expression of extra‐sutural bones. The present study examines the effects of fronto‐occipital and occipital‐only deformation on the occurrence of extra‐sutural bones through an analysis of 59 deformed and undeformed crania from the Philippines. Relative to the undeformed crania, both deformed samples showed an elevated number of extra‐sutural bones. Using two different statistical tests, we identified a significantly higher occurrence of extra‐sutural bones at two distinct cranial localities for both the fronto‐occipitally deformed crania (coronal suture and asterion) and for those showing only occipital flattening when compared to the undeformed crania (lambdoidal and asterion). However, as our data reveal, individuals with highly elevated occurrences of extra‐sutural bones are not necessarily deformed. As such, we argue that deformation practices may have a positive impact on the formation of extra‐sutural bones; however, future studies using larger samples of deformed and undeformed crania—ideally from the same site—will be necessary to distinguish between the influence of cranial deformation on extra‐sutural bone formation relative to other population factors which may play a role in shaping variation in this feature.

An investigation into the practice of cranial deformation among the Pre-Columbian peoples of northern Chile

An investigation was carried out into the practice of artificial cranial deformation (ACD) among the Pre-Columbian inhabitants of northern Chile. Four hundred and fifteen skulls, representing a period of 7000 years, were examined of which 88.9 per cent were deformed. The practice was carried out equally between men and women. The techniques used in head deforming varied over time among the different cultural groups that inhabited the region. By analysis of the methods used in ACD, it can be demonstrated that head deforming may yield information significant to the study of the political and cultural changes that occurred throughout the prehistory of the region. As a form of stylistic behaviour, which may be viewed as a strategy of information exchange, ACD was found to be a significant cultural artifact that may serve to mark territory or social boundaries, reaffirm ethnicity, and maintain and strengthen exchange networks. Certain pathological consequences were found to be the result of ACD, including an increase in the prevalence of wormian bones, occipital bone necrosis, and an abnormal closing pattern of the cranial sutures. No evidence was found that ACD is associated with a deviated nasal septum or osteomas of the external auditory canal.     

Αge‐associated Variation and Sexual Dimorphism in Adult Cranial Morphology: Implications in Anthropological Studies

The current paper explores the impact of age and sex on adult cranial shape and size variation in the documented collections from St Bride's and Spitalfields. The scope is to assess the extent to which it is valid to pool age and sex groups in inter‐population comparisons that use cranial data. For this purpose, age and sex differences in cranial shape and size were explored using multivariate analysis of variance, Discriminant analysis and Mann–Whitney tests. The results suggest a clear change in cranial shape with increasing age; however, this change is not statistically significant. Therefore, it is justifiable to pool different age groups in bioarchaeological analyses. Increasing age also has a minimal impact on cranial size among females, whereas among males, its impact is small but statistically significant. Finally, cranial shape and size are significantly different between males and females, irrespective of their age. This dimorphism can be used for the assessment of sex, although attention should be given to over‐classification problems when using discriminant analysis.

A review of trepanations in Anatolia with new cases

In this study, trepanations in ancient Anatolia were discussed from a historical perspective. Trepanations were studied in respect to temporal and spatial distribution, sex and age distribution, techniques and reasons, completeness, healing and number of holes. Forty individuals from 23 different Anatolian settlements are identified to have undergone trepanations. Cranial trepanations in Anatolia show a distribution over a period of 10 000 years ranging from the Aceramic Neolithic period to the Late Ottoman period and spread to whole Anatolia. The greater majority of the individuals had single trepanation orifices while only four individuals were identified with multiple holes. It is observed that the surgical procedure was predominantly carried out on males in Anatolia. Main techniques of trepanations used in Anatolia are drilling and cutting. Early cases of trepanation were made by drilling; however, this technique has been used for cranial surgery until the Ottoman period. Scraping and rectangular sawing techniques first applied in the Early Bronze Age. The boring‐and‐cutting technique was only applied in the Iron Age. More than half of the trepanations practiced due to cranial trauma. Training and treatment besides of cranial trauma are also considered as likely causes of trepanations in Anatolia. It is concluded that trepanation techniques are similar to South America and the Mediterranean region rather than Europe. Copyright © 2010 John Wiley & Sons, Ltd.     

Phylogenetic interpretation of eggs and eggshells: implications for phylogeny of Palaeognathae

This oological analysis supports Palaeognathae monophyly, and places Dromornithidae within Neognathae, the sister clade of Paleognathae. This Dromornithidae relationship is congruent with a recent phylogenetic hypothesis, based on cranial characters, that differs from the original assignment of this group of extinct birds to the Palaeognathae. Minor differences exist between previous palaeognath phylogenetic hypotheses and that obtained from this research. Some of the topological disparities might be influenced solely by inclusion of more fossil taxa in this analysis compared with those considering either molecular or skeletal characters. Surprisingly, oological data differentiate the Australasian palaeognath taxa from those of Africa and South America; this phylogenetic topology conforms to the paleognath geographic distribution.

Regardless of the issues related to Paleognathae, results show that oological characters permit the differentiation of groups at a generic level, thus validating the use of eggs and eggshells as a source of evolutionary characters.     

Earliest hunters and gatherers of South America

Traditional syntheses of the archaeology of the late Pleistocene period in South America have focused primarily on the peopling of the continent by North American cultural groups and on identifying associations among regional sites. This focus has tended to ignore the widespread culture diversity of the period and the possible effects of different paleolandscapes on human migration and colonization, such as the presence of unglaciated tropical and temperate environments in the northern lowlands, the gateway to the interior. The earliest known cultural assemblages are characterized by various unifacial and bifacial lithic industries that may represent regional processes reminiscent of an Archaic lifeway. The major archaeological sites and associated artifact assemblages are examined in terms of regional and continental patterns of environmental and cultural change. Results suggest that the Pleistocene archaeological record of South America must be explained in its own terms and that the events and processes producing this record either occurred earlier than previously thought or are very different from those in North America.     

South–South Cooperation and the Geographies of Latin America–Caribbean Integration and Development: A Socio‐Spatial Approach

Structured around the case of South–South cooperation in the construction of “complementary economic zones” among the member states of the ALBA‐TCP, Petrocaribe, CARICOM and MERCOSUR, this article argues for a socio‐spatial approach to the study of the Latin America–Caribbean integration and development. Two interrelated arguments are developed: first, in contrast to methodologically nationalist approaches, which typically view the regionalisms that are to form the complementary economic zones as ideologically separate, incompatible or conflicting projects, a socio‐spatial approach in conjunction with a South–South cooperation analytical lens explains their commonality and, subsequently, their interrelatedness and convergence. Second, while this South–South cooperation space is not per se non‐capitalist, a socio‐spatial analysis also facilitates “seeing” the production of a socialist “counter‐space” within this South–South cooperation structure.     

Chiefdoms in northern South America

The multiple and varied trajectories of chiefdom development in northern South America (and adjacent Central America) offer a rich opportunity for evaluating generalizations about the processes of chiefdom development. Sequences of the south coast of Ecuador, the Alto Magdalena, Calima, the Muisca region, Barinas, and the Tairona region are well enough documented to attempt to use in this way. Although centralized hierarchical societies develop in all these regions, there are many differences in the character of centralization and hierarchy and in the pacing of the development, and none of the traditionally proposed forces of social change is entirely adequate to account for these cases. Attention to the role played by competition between aspiring chiefs and their factions offers promise for more satisfactory generalizations that could be evaluated through further comparative study.     

Variation in North American dart points and arrow points when one or both are present

The appearance of the bow and arrow in North America as a weapon-delivery system is predicted to have prompted an increase in variation among antecedent projectile points that tipped darts propelled by atlatls. Attributes of dart points are expected to display greater variation with the appearance of the bow as prehistoric artisans experimentally sought points that worked effectively as arrow points. Attributes of arrow points are predicted to also initially display much variation. Subsequent to the initial burst of variation, less-effective variants of attributes were winnowed out, causing a reduction in variation of attributes of both dart points and arrow points. Both coefficients of variation for individual attributes and summed coefficients of variation for multiple attributes of three sequences of projectile points from evolutionarily independent areas in North America confirm these predictions.     

The Political Economy of Industrialization: A Comparison of Latin American and East Asian Newly Industrializing Countries

ABSTRACT The paper analyses the industrial performance of two East Asian (South Korea and Taiwan) and three Latin American (Argentina, Brazil and Mexico) newly industrializing countries. It argues that the better performance in East Asia is not due simply to differences in trade orientation or the degree of state intervention, but rather to the effectiveness of intervention. This is explained in terms of the relative autonomy of the state and the structuring of the state apparatus in the two regions. The historically determined class structure and the international context led to much greater state autonomy in East Asia than in Latin America. The last part of the paper shows a number of ways in which this greater relative autonomy has contributed to rapid industrial growth in East Asia in comparison with Latin America.     

Agricultural Origins and Frontiers in South Asia: A Working Synthesis

The accumulation of recent data from archaeobotany, archaeozoology and Neolithic excavations from across South Asia warrants a new overview of early agriculture in the subcontinent. This paper attempts a synthesis of these data while recommending further systematic work and methodological developments. The evidence for origins and dispersals of important crops and livestock from Southwest Asia into South Asia is reviewed. In addition evidence for indigenous plant and animal domestication in India is presented. Evidence for probable indigenous agricultural developments in Gujarat, the Middle Ganges, Eastern India, and Southern India are reviewed. An attempt is made to highlight regions of important frontiers of interaction between early farmers and hunter-gatherers. The current evidence suggests that the Neolithic trajectories in different parts of South Asia differ from each other. Indigenous centers of plant domestication in India also differ from the often discussed trajectory of Southwest Asia, while suggesting some similarities with agricultural origins in Africa and Eastern North America as well as secondary agricultural developments on the peripheries of Eurasia.

Trade and culture: the ongoing debate

ABSTRACT

The debate over how to reconcile trade liberalization with cultural policy is a long-standing one. There is great variation in how countries have navigated this debate. Furthermore, evolving individual policy approaches show noteworthy dynamism, largely in response to domestic politics, shifts in the international trading system and technological developments. This special issue explores different approaches to the trade and culture debate across geographic space, as well as the evolution across time through analysis of six cases – Canada, the European Union, South Africa, Latin America, the United States and China.     

GENERATION OF SYNTHETIC EARTHQUAKE ACCELEROGRAMS USING SEISMOLOGICAL MODELLING: A REVIEW

A stochastically based seismological model is described in this paper and used to generate synthetic accelerograms that are considered representative of intraplate earthquake events recorded on rock. The model, whilst well publicised in the seismological literature, is discussed and reviewed in this paper from an engineering perspective. The key factors influencing the frequency properties of the Fourier spectrum of the earthquake ground motion are presented and the differences observed between regions such as between eastern and western USA axe discussed. A procedure to generate representative artificial accelerograms from the Fourier spectrum is described. Average response spectra derived from these synthetic accelerograms are then compared with a selection of response spectra derived from recorded accelerograms to test and substantiate the model. The application of the seismological modelling approach to regions outside North America and the implications of the Displacement Based prinicples on the future development of seismological modelling have been addressed and discussed in the paper.     

First report of a South American short-faced bears' den (Arctotherium angustidens): palaeobiological and palaeoecological implications

Here we report the first example of associated short-faced bear fossils from South America. The specimens represent three individuals referable to the Ensenadan (early to middle Pleistocene) species Arctotherium angustidens (Ursidae, Tremarctinae), the giant South American short-faced bear. Although the fossil record of short-faced bears in South America is very rich, they have not previously been recorded in association. These three individuals were found in a cave during quarry exploitation. We suggest that these bears represent the first record of a family group and open the discussion about cave utilization and hibernation or torpor by South American short-faced bears.

Regional governance and legitimacy in South America: the meaning of UNASUR

Over the last decade, rapid changes to development models and market rules have led—yet again—to a revision of the meaning of regionalism, bringing to the fore the role of regional organizations in anchoring democracy and supporting progressive social policies. This is particularly the case in South America, where the presence of regional organizations in public policy‐making is a subject of increasing scrutiny. This article examines new forms of politically sensitive regional governance in South America, focusing in particular on the case of the Union of South American Nations (UNASUR). It shows how contemporary South American regionalism bypasses the questions of trade and investment that dominated earlier schemes of regionalism in order to focus on shoring up democracy and managing the regional social deficit. The article explores UNASUR's actions in two policy areas: supporting the regional democratic norm and health policy. UNASUR, this article argues, is developing a hybrid form of output‐focused legitimacy that rests on a combination of credible commitments to welfare promotion, especially for the poor, and the pursuit of collective public goods, alongside a robust defence of quite minimal but uncontroversial standards of procedural democracy across the region. The analysis challenges the view that regionalism has failed in South America and identifies instead the emergence of a new sort of highly political regionalism. We call for UNASUR to be taken more seriously in the literature on comparative regionalism and, indeed, for a revision of how regionalism more widely is understood in Latin America.
