On yellow and red pigmented bones found in Mayan burials of Jaina

In the island of Jaina, Campeche, red and yellow pigmented bones have been found. The study of the yellow and red colors in these burials is important for their possible interpretation, either religious, intentional coloring, or to understand taphonomic processes such as reactions of the original pigments with other compounds. Yellow color on bones is unusual in prehispanic burials.     

Changes in human bones boiled in seawater

The differences between boiled or unboiled bones are not often studied. However, they are crucial to understand postmortem rituals and to establish defleshing procedures and mortuary practices. In this work, human bones boiled in sea or fresh water are characterized. The bone composition, as well as the compounds present in the resulting materials, shows that salt alters the boiling process mechanism. Hence, from structural and morphological criteria, it is possible to distinguish if a bone has been boiled in salt or fresh water. In both sets of samples, the smoothness of the bone surface depends on boiling time, but only in bones boiled in seawater, filaments are observed apparently pouring out of the pores.Those differences which are mainly morphological (smoothness of the surface) are explained in terms of a collagen diffusional mechanism favored by sodium and chloride ions. For a boiling time of 6 h, the surface is covered by a thick layer or crusts of degraded collagen. Experiments with seawater may be used as model experiments to simulate taphonomical alterations in bones exposed to salt water.     

The Power and Limits of Cultural Myths in Portugal's Search for a Post-Imperial Role

The central role in Portuguese political culture of the identification of Portugal as a colonizing power legitimized a massive mobilization and violent response to the perceived existential threat of decolonization in the shape of prolonged wars in its main African colonies (1961–1974). If, however, this cultural myth of a Greater Portugal overseas was so powerful, how was decolonization eventually possible? The accumulated human and economic cost of facing three simultaneous, protracted anti-colonial insurgencies eroded this overseas creed and made Catholic and Marxist strands of anti-colonialism increasingly attractive to younger, more internationally connected, Portuguese elites. What also happened, however, this article will argue, was a refashioning of the powerful cultural myth of a special connection between Portugal and tropical Africa. A colonial myth was turned into a post-colonial myth legitimizing decolonization as a mutual and fraternal liberation from the same oppressive regime without a loss of strong ‘natural’ cultural bonds. More widely, the article aims to show that we cannot ignore the importance of cultural factors in international history. Our approach in this article is pluralist and this means that while arguing strongly for taking culture seriously and focusing on it, it does consider other, including more material, dimensions of power.     

A Preliminary Scheme for the Economic Regionalization of Cuba

The authors propose a scheme of economic regionalization for Cuba, based on Soviet Marxist principles. These include the idea of objective existence of a region, independently of man's will; the need for considering future developmental prospects; energy supply; the prerequisites for integrated development of the regional economy; the presence of a regional specialization; maximum promotion of a geographical division of labor, and the factor of the country's defense capability. The resulting system of six regions in described.     

Dental Anomalies in the Mandible of Capra pyrenaica: Presence of Two Permanent Fourth Premolars in a Pleistocene Wild Goat from Arlanpe Cave (Bizkaia,Northern Spain)

In this study, we report a case of duplication of a lower fourth premolar (P₄) on an Iberian wild goat from the archaeological site cave of Arlanpe, (Lemoa, Bizkaia, Northern Spain). The preserved right mandible corpus displays two premolars and the first molar (M₁). Both premolars conform in size and general shape to fourth premolars (P₄) but the medialmost of the two is rotated 90° counterclockwise, and thus, its wear pattern is different. The comparative analysis to other bovids and the relative scarcity of this anomaly compared to other cases of polydontia and hypodontia suggest that it is a developmental defect consisting in the duplication of the tooth germ, and we doubt on the potential of this abnormality as a territorially based indicator of past wild populations as has been previously proposed.

FRAGMENTATION AND CLUSTERING IN VERTICALLY LINKED INDUSTRIES*

ABSTRACT This paper models the location of two vertically related firms in a low labor cost country and in a country with a large market. The upstream industry is more labor intensive than the downstream industry. We find that spatial fragmentation occurs for low values of the input‐output coefficient and intermediate values of the transport rate, particularly if the countries are very asymmetric in size. Otherwise, we obtain agglomeration either in the low cost country (when the transport rate is low) or in the large market (when the transport rate is high). Multiple agglomerated equilibria arise when the transport cost of the intermediate good is significant.     

“Eternal Sunshine of the Spotless Mind”: Archaeology and Construction of Memory of Military Repression in South America (1960–1980)

During the era of dictatorships in Latin America, opposition was controlled by different methods—such as exile, detention, and murder. Repressive devices were reinforced by means of limiting information to ordinary people. Written sources on clandestine repression are scarce and fragmentary. As a matter of fact, most documents on the subject were destroyed by military regimes in recent past. Therefore, archaeological analyses might help us to shed light on repressive mechanisms, recovering missing people’s history and remains.     

The Dynamics of Regional Disparities in Central and Eastern Europe during Transition

This paper examines the evolution of territorial imbalances in per capita income in the Central and Eastern Europe regions between 1990 and 2001. In order to overcome the limitations of conventional convergence analysis, we have combined a non-parametric approach that allows us to study the dynamics of the entire cross-section distribution, with a series of theoretical results and measures taken from the literature on personal income distribution. The results obtained show an overall reduction in regional inequality over the study period. This process has been compatible with the simultaneous presence of between-country convergence and within-country divergence. Likewise, we have observed a reduction in the development gap between the sample regions and Western Europe. In any event, the polarization of the distribution under consideration has decreased, while the registered level of intra-distribution mobility is relatively low. Furthermore, the analysis highlights the important role played in explaining the distribution dynamics by factors such as the national component, spatial location, productive structure, agglomeration economies and the percentage of gross domestic product devoted to investment.
