Taphonomy of ungulate ribs and the consumption of meat and bone by 1.2-million-year-old hominins at Olduvai Gorge,Tanzania

The phenomenon of equifinality complicates behavioral interpretations of faunal assemblages from contexts in which Pleistocene hominins are suspected bone accumulators. Stone tool butchery marks on ungulate fossils are diagnostic of hominin activities, but debate continues over the higher-order implications of butchered bones for the foraging capabilities of hominins. Additionally, tooth marks imparted on bones by hominins overlap in morphology and dimensions with those created by some non-hominin carnivores, further confounding our view of early hominins as meat-eating hunters, scavengers or both. We report on the manual/oral peeling of cortical layers of ungulate ribs as taphonomically diagnostic of hominoid/hominin meat- and bone-eating behavior that indicates access to large herbivore carcasses by hominins at the site of BK, Olduvai. Supporting these inferences, we show that certain types of rib peeling damage are very rare or completely unknown in faunas created by modern carnivores and African porcupines, but common in faunas modified by the butchery and/or consumption activities of modern humans and chimpanzees, during which these hominoids often grasp ribs with their hands, and then used their teeth to peel strips of cortex from raggedly chewed ends of the ribs. Carnivores consume ungulate ribcage tissues soon after kills, so diagnostic traces of hominin butchery/consumption on ribs (i.e., peeling and butchery marks) indicate early access to ungulate carcasses by BK hominins. Tooth marks associated with the peeling and butchery marks are probably hominin-derived, and may indicate that it was not uncommon for our ancestors to use their teeth to strip meat from and to consume portions of ribs. Recognition of rib peeling as a diagnostic signature of hominoid/hominin behavior may also aid the search for pre-archaeological traces of hominin meat-eating.     

Patent Places: Size Matters

In this paper I investigate the United States urban system of technical advance by analysis of metropolitan patent data. Residents of metropolitan areas obtain most of the patents awarded to Americans and the largest areas predominate, signifying that urbanization externalities facilitate invention. The advantages of large areas arise from lopsided concentrations of technologically intensive manufacturing and an uneven distribution of well-educated people. Location with respect to the traditional manufacturing belt also plays a role. Metropolitan residents in the manufacturing belt remain the most industrious inventors. The contribution of leading educational and research institutions to technical advance is manifest in small urban centers and outside the traditional manufacturing belt.     

Chile 1997-1998: The Revenge of Incomplete Democratization

The author seeks to analyse the repercussions and consequences of the Pinochet affair for Chilean domestic politics. He explains how the legacy of seventeen years of authoritarian rule has shaped the deep divisions within Chilean society regarding the prosecution of the Chilean former dictator in the London courts. Chile is an incomplete democracy and Pinochetism is very much alive in Chile today.
The author is very critical of the role played by the current Chilean government and political class, for their behaviour during the affair. In granting a special mission to the General which gave him immunity and later supported his legal case after initial hesitation, the government has shown confusion that has not advanced the case for full democratization and justice in Chile. The ambiguous behaviour of the political class during the episode has discredited its prestige in the eyes of public opinion. Chilean society, according to the author, has missed an opportunity to advance justice and the dignity of the country.     

Prehistoric radio‐ulnar synostosis: implications for function

Proximal radio‐ulnar synostosis (RUS) may occur congenitally, either as an isolated condition or as part of a syndrome, or it may occur as a secondary complication of forearm trauma. We provide a key for the differential diagnosis of congenital versus traumatic RUS, and for differentiation between types of congenital RUS. Congenital cases (CRUS) include absence of fracture, radial head abnormalities, radial shaft bowing, and absence of a sigmoid notch, whereas post‐traumatic RUS results from either radial neck fracture or evulsion of the biceps brachii, followed by ossification of the resulting haematoma or of the interosseous (IO) membrane. Congenital cases include those which result from incompetent differentiation of the single mesenchymal mass that gives rise to the radius and ulna (Type I) and those that result from radial head dislocation in utero, resulting usually from humeral or ulnar defects (Type II). Type II CRUS can be differentiated by the presence of radial overgrowth, among other factors. Following these guidelines, we describe and compare the morphology of three congenital cases from North America. Two present bony fusions and one a functional fusion with radial overgrowth. In each case, CRUS significantly limits both supination and pronation. Despite differences among the cases, several morphological accommodations are shared as a result of fixation in the neutral (semi‐pronated) position. These changes include the ventral migration of the IO crests of the ulnae and enlargement of the dorsal tubercles of the radius. Understanding the pattern of accommodations made in the face of compromised function ultimately increases our understanding of the patterns of growth in normal functional regimes.

Mortuary patterns in burial caves on Mangaia,Cook Islands

The behavioural, cultural, and political implications of archaeological human remains in non‐mortuary, possibly culinary, contexts requires that we understand the range of mortuary practices in a particular region. Although several rockshelter sites on Mangaia, Cook Islands have yielded burned, fragmentary human bones in earth ovens that seem to support archaeological models and ethnohistoric accounts of ritual sacrifice and cannibalism, the absence of data on the range of Mangaian mortuary patterns obscures these interpretations. We describe burial patterns based on 40 above‐ground interments representing at least 92 individuals in caves of Mangaia, Cook Islands, in order to begin to develop an island‐wide perspective on mortuary patterns. Sampling both pre‐ and post‐European contact sites we found that multiple interments dominate probable pre‐contact burials (73%, 19 of 26) and single interments dominate post‐contact contexts (80%, eight of ten burials), probably reflecting the influence of Christianity on mortuary ritual. Subadults were more frequent in all post‐contact contexts suggesting alternative burial places, probably church cemeteries, for adults. Burial cave remains are broadly consistent with ethnohistoric accounts of interment in caves, however, they also illustrate additional burial practices and differences between time periods, such as primary body position and the role of multiple‐individual interments, which are not discussed ethnohistorically. The mortuary practices in Mangaian burial caves differ from burials associated with marae and seem completely unrelated to the presence of highly fragmentary and burnt human remains in pre‐contact rockshelter middens elsewhere on the island.

EMPIRICAL STUDIES IN INDUSTRIAL LOCATION: AN ASSESSMENT OF THEIR METHODS AND RESULTS*

ABSTRACT This paper surveys recent evidence on the determinants of (national and/or foreign) industrial location. We find that the basic analytical framework has remained essentially unaltered since the early contributions of the early 1980s while, in contrast, there have been advances in the quality of the data (more firm and plant level information, geographical disaggregation, panel structure, etc.) and, to a lesser extent, the econometric modeling. We also identify certain determinants (neoclassical and institutional factors) that tend to provide largely consistent results across the reviewed studies. In light of this evidence, we finally suggest future lines of research.     

Paleoparasitological results from coprolites dated at the Pleistocene–Holocene transition as source of paleoecological evidence in Patagonia

Coprolites attributable to humans, dated from the Pleistocene–Holocene transition, obtained from the archaeological site Cerro Casa de Piedra, Santa Cruz Province, were examined for parasites. The feces were processed by rehydration and spontaneous sedimentation using conventional parasitic procedures. Helminthic eggs recovered were identified as Trichuris sp., Calodium sp., other capilariids, and ancylostomid (Nematoda), probably Hymenolepis sp. and anoplocephalid (Cestoda); one oocyst attributable to Eimeria macusaniensis (Apicomplexa) was also found. According to the life-cycles and specificity of the parasites found, it is possible to suggest that some species (i.e., E. macusaniensis and Calodium sp.) represent parasites in transit or pseudoparasitism. Paleoparasitological results revealed the existence of an intensive relationship between parasites and humans in the Pleistocene–Holocene transition in Patagonia. Evidence suggests an early association among parasites, rock shelters and hunter–gatherers in the region. It is also postulated that the ancient lifestyles associated with caves and rock shelters were conductive to illness.     

The archaeology and paleoenvironment of an Upper Pleistocene hyena den: An integrated approach

Data of high resolution for reconstructions of archaeological site formation processes can be obtained only by the use of precise excavation methods and comprehensive recovery techniques using fine-mesh water screening, followed by meticulous sorting and quantitative studies of all the small organic components from the screens. These methods are generally used at human occupation sites, but are not often employed at paleontological or mixed human-carnivore sites. At the site of Bois Roche, an Upper Pleistocene hyena den, we have used these meticulous recovery techniques in combination with absolute dating, geoarchaeological observations, taphonomic analyses, studies of microvertebrates and pollen analysis. Correlation of the site environmental data from pollen and microvertebrate assemblages with the vegetation record of a deep-sea core taken in the Bay of Biscay have allowed us to constrain the ages provided by ESR dating of bovid teeth and to reconstruct the physical environment of the site with a degree of confidence rarely achieved by the use of fossil remains from archaeological sites alone.
