Central Park against the streets: the enclosure of public space cultures in mid-nineteenth century New York

The industrialization of New York and its rise to economic dominance brought about a major restructuring of street life and unleashed an array of contradictory everyday urban cultures. In a still under-regulated environment, the commoning of public space became a key sociospatial capital that helped the working classes resolve their reproduction in a way the elite found disturbing and far removed from the civic order they were trying to instil. This article draws on recent theorizations of the commons/enclosure dialectic to develop a comparative analysis of the cultures of public space use vis-à-vis the practices prescribed by Central Park in its attempt to reform everyday spatialities. The park is understood here as an early episode in the project of imposing new social relations through the enclosure of public conduct—a first effort to tame the urban commons and prevent the subaltern appropriation of public space. Following a preliminary discussion of the economic and social determinants and configuration of the material cultures of public space use in Manhattan, the article studies the park's strategies as a special type of enclosure, consisting not of the usurping of common land for private profit but of the mobilization of public space to shift behaviors from one regime of publicity to another.     

Complementarities Between Universities and Technology Institutes: New Empirical Lessons and Perspectives

This paper investigates the different roles played by universities and technology institutes (TIs) as innovation partners of firms. Comparing the characteristics of Spanish firms collaborating with these agents allows us to better define complementarities among the target groups of these organizations. Our findings show that those firms collaborating with universities are bigger, have higher internal capabilities and are less dependent on their external relationships while firms collaborating with TIs are smaller, have weaker internal capabilities but are more open to their environment and thus more reliant on external sources. We point to the implications of these findings for regional development. Universities have a role as partners of more technologically advanced firms. TIs, on the other hand, partner those firms, which though also quite advanced, require more external help in their innovation processes. These results should help policy-makers in the definition of more complex regional strategies and the provision of tools aimed at different goals. Managers of universities, TIs and client firms should find these results of help in developing more positive collaborations with one another.     

Metapopulation Processes in the Long-Term Colonization of the Andean Highlands in South America

This paper analyses the importance of the South Central Andean High Puna megapatch, above 4000 masl, in the history of late Pleistocene exploration and colonization of the Atacama Desert, including the contrasting habitats that exist towards the hyperarid Pacific Ocean coast or the ecosystems bordering the tropical forests, on the western and eastern sides of the Andes, respectively. These ecosystems, which were firmly established by the end of the Pleistocene, are examined as key factors in the history of human peopling. The social, demographic and climate conditions associated with the peopling processes are discussed in relation to the appropriate technological, subsistence and settlement strategies developed by pioneer populations, who for their initial settlement selected highly productive patches where water and fauna converged. Based on concepts derived from metapopulation theory, all relevant archaeological paleoecological data from both sides of the Andean Cordillera are presented and discussed. It is concluded that the pioneer occupation of the high Puna megapatch was a gradual process, related to an emergent Andean human mobility system that connected a wide range of altitudinally staggered habitats. Moreover, we suggest that divergent cultural trajectories evolved since the early Holocene, affecting highland, lowland and coastal habitats.

     

Technical Strategies for Conservation of Earthen Archaeological Architecture

The preservation of earthen architectural heritage is extremely complex due to the diversity of its constituent materials and potentially rapid physical deterioration. Interventions on historic earthen architecture throughout the world have shown very distinct levels of success, but there is no single procedure or combination of conservation procedures that guarantee success. One of the problems is the lack of knowledge about the behaviour of soil as the material component, and its relationships both with other materials, and associated natural and cultural environments. This article analyses some technical considerations that have influenced the preservation of earthen archaeological remains, through critical analysis of the existing bibliographic references from the proceedings of specialized international conferences that have taken place in the last twenty years.     

None daring to make us afraid

ABSTRACT

J.W. Breyer, the young South African military administration's first game warden in Namibia, was based at Namutoni on the south-eastern margin of the Etosha pan. Breyer died a lonely death and a meticulous inventory was rendered of Breyer's estate. Viktor Franke, the German commander in south-western Africa, and Cocky Hahn, the second South African commissioner of native affairs stationed at Ondangwa, similarly left a visual record of their intimate surroundings. An itinerary of their material worlds and hence of colonialism in Namibia is here revealed using photographs and other evidence, highlighting some of the complexities of the cultural practices of colonial administration and policing in southern Africa.     

Petrographic thin sections and exotic rocks provenience among hunter–gatherer societies in the eastern Pampa–Patagonia Transition (lower basin of the Colorado River,Argentina)*

Lithic assemblages recovered from sites located in the eastern Pampa–Patagonia transition include a great diversity of raw materials, some from neighbouring regions, such as the Humid and Dry Pampa subregions and Northpatagonia. Lithic raw material assignments to specific procurement areas were preliminarily proposed based on macroscopic characterizations. The aim of the paper is to present the results obtained from the petrographic thin sections of archaeological artefacts from Middle and Late Holocene sites recorded at the study area. The analyses corroborate most of the macroscopic determinations, and more detailed knowledge of the acquisition areas of these raw materials was obtained.     

GPR and inductive electromagnetic surveys applied in three coastal sambaqui (shell mounds) archaeological sites in Santa Catarina state, South Brazil

In this article, GPR – Ground Penetrating Radar and inductive electromagnetic (EM38 equipment) results are presented for three archaeological sites of shell mounds located between Laguna and Jaguaruna cities, mid-southern coast of Santa Catarina state, Brazil. The Jabuticabeira II, Santa Marta IV, and Encantada III sites were studied. These sites consist of carbonate shell mounds built by societies that inhabited this region during the pre-colonial period (7.5–1.3 ky BP). Geophysical responses obtained in these archaeological sites had allowed the identification of anomalous regions related to archaeological point targets as well as continuous targets, correlated to the shell mound's structure and buried geologic features. GPR numerical modelling studies were done in order to evaluate the performance of the GPR method in relation to materials found in that environment, besides helping interpretations of real results. The synthetic GPR model was a good match with real data obtained in the field. So, the real and synthetic results serve as a reference guide to direct excavation activities in these archaeological and geological structures. In the Jabuticabeira II shell mound, lithic materials and burials were found amidst archaeological layers characterized by sediment rich in organic material, ferruginous concretions, and loose shells. In the Santa Marta IV archaeological site, a concentration of ceramic materials, burials and fireplaces were found. In the Encantada III site, a strong anomaly characterized by a hyperbolic reflection was related to the presence of a silicified tree root; a great example of ambiguity in shallow geophysics interpretation in archaeological applications. Results functioned as a guide to archaeological excavations, allowing cost and time reduction as well as contributing to improve the knowledge of these archaeological sites situated in southern Brazil.     

Reduction of topography effect in inductive electromagnetic profiles: application on coastal sambaqui (shell mound) archaeological site in Santa Catarina state, Brazil

We present results of electrical conductivity profiles obtained with inductive electromagnetic geophysical method in Santa Marta archaeological site, Santa Catarina State, southern Brazil. This site is a sambaqui (shell mound), in which several human occupation remains are found during pre-colonial period such as buried lithic and bone artifacts, fire-place, etc. Most of these mounds include as well many human burials, which, in many cases, point to funerary ritual as a main agency for mound building. A set of profiles of apparent electrical conductivity and magnetic susceptibility was acquired in two sites aiming the identification of geophysical anomalies with potential interest for excavation. To enhance conductivity data, we applied an effective procedure to remove topographical effects in the apparent conductivity measurements, which are rather conditioned by the presence of a variable water table depth or conductive sediment layer. A linear dependence among conductivity values and the site elevation provided a simple linear model to remove the influence of topography. Corrected electric conductivity maps substantially improved the definition of anomalies, many of them rather subtle in raw data images. Corrected maps also show a better adherence with magnetic susceptibility maps, both of them identifying archaeological structures of interest: a well-structured fire-place and a concentration of ceramic fragments.
