Advances in the archaeology of the Pampa and Patagonia

Archaeological data reveal two distinctive cultural adaptations on the Pampa and Patagonia of Argentina: terrestrial hunter-gatherers in the former and most of the latter region and maritime hunter-gatherers along the southern extreme. Both adaptations were achieved by the end of the fifth millennium B.C. Thereafter, a stable equilibrium was maintained, with a slow drift toward greater emphasis on resources providing the maximum return for the least effort. The high productivity of the Fuegian environment sustained a population 30 times greater than occupied the Pampa and continental Patagonia prior to Araucanian penetration in the sixteenth century A.D. The long-term stability is attributable to the absence of environmental or demographic pressures or encroachments by neighboring groups, which might have made more intensive exploitation of the environment necessary.     

Landscape interpretation with augmented reality and maps to improve spatial orientation skill

Landscape interpretation is needed for navigating and determining an orientation: with traditional cartography, interpreting 3D topographic information from 2D landform representations to get self-location requires spatial orientation skill. Augmented reality technology allows a new way to interact with 3D landscape representation and thereby facilitate the orientation of oneself in respect to the environment to determine goal location. This paper analyses if AR spatial landform improves the learner’s spatial orientation skill measured with the perspective taking/spatial orientation test by paired sampled t-tests. A workshop was conducted with 123 university students (63 treatment group, 60 control group) in which students had to identify locations and routes based on the interpretation of the relief, represented by AR. Results of the workshop showed an improvement in spatial orientation skill of 20.14 degrees average gain in the treatment group. Students who were not subject to the workshop (control group) did not improve their spatial orientation skill. The possibility of using free AR three-dimensional applications and exploit the potential of tablets and smart phones, which are widespread today, makes it possible to design and implement strategies for the development of spatial skills in formal teaching in the scope of Geography in higher education.     

Application of Particle Motion Technique to Structural Modal Identification of Heritage Buildings

Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).     

SEM,EPR and ToF-SIMS analyses applied to unravel the technology employed for pottery-making by pre-colonial Indian tribes from Pantanal,Brazil

The present work aims at elucidating the technology applied in the fabrication of ceramic objects by the ancient ceramists that inhabited the western border of Pantanal, Mato-Grosso do Sul, with the help of a multidisciplinary approach making use of chemical and physical methods of analysis. The potshards under study show the presence of different types of additives, as determined by scanning electron microscopy (SEM) and time of flight secondary ion mass spectrometry (ToF-SIMS). The dispersion of the additives within the ceramic matrix was also addressed by SEM, which shed light on the mounting technique used by the potters to assemble the ceramic vessels. Moreover, the tensile strength conferred to the pottery by the use of a specific type of additive was evaluated by applying a mechanical test. These results were correlated with the firing temperature of the potshards, determined by means of electron paramagnetic resonance (EPR).     

PERFECT REPRESENTATIONS OF SOVIET PLANNED SPACE

The article looks at mono‐industrial cities in the Baltic States during the Soviet era. In terms of economy, ethnicity and their urban appearance these heterotopic towns were outposts in the integration of the occupied European‐like territories into the Soviet Union. Thanks to the principles of planning and state‐favoured development that were applied across the Soviet Union, these towns, built for Russian speaking immigrants, stood out from the surrounding patterns of settlement that had developed naturally over time. The uranium producing town of Sillamäe in Estonia was built in secret and with lightning speed amidst the panic concerning the atom bomb immediately after the war, and provides us with a perfect model of Stalinist urban development. Stu?ka, built in the 1960s near a hydro‐electric power station in Latvia and Snie?kus, built in the 1970s next to a nuclear power station in Lithuania, were less separated from the surrounding landscape, but both provide a perfect example of Soviet modernism, which had been learned from mass‐housing in the West.     

Anthropologie, psychhanalyse et «civilisation» du brésil dans l'entre-deux-guerres

This study concerns the moral regulation of the Person in Brazil from the twenties to the end of the forties, from the point of view of the intense academic relationship between anthropology and psychoanalysis. It deals with the conditions under which that dialogue took place: the general crusade for the «civilization» of the country, between the central State initiatives in the promotion of hygiene and education and the medical, intellectual debates about the «African» heritage and the possibility of surmounting cultural «backwardness».     

THE FOOD VALUE CHAIN AS A LOCUS FOR (DIS)AGREEMENT: CONVENTIONS AND QUALITIES IN THE SPANISH WINE AND NORWEGIAN SALTED COD INDUSTRIES

According to the theory of conventions, food value chains (FVCs) involve a complex array of actors who share an agreement about the qualities embodied in their particular foodstuff. Nevertheless, that agreement is continuously challenged by changes in consumer markets. Therefore, I argue that FVCs able to adapt those qualities to new trends will perform better than FVCs whose commitment to certain qualities leads to a misunderstanding between producers and consumers. The organization of the chain itself, the values of national regulatory frameworks, and the goals of the national innovation system are discussed as factors that shape an FVCs' ability to re‐arrange that core agreement. By using professional reports, statistical records and personal interviews, this article focuses on two FVCs that have experienced contrasting trajectories in recent decades in the Spanish market: the wine industry located in the region of Castile and Leon (Spain) and the Norwegian salted cod industry. The growing wine FVC has achieved a successful agreement about a set of qualities linked to nature, tradition, and place, all of them guaranteed by the reputation of the Designation of Origin (DO) system. In contrast, the salted cod FVC is losing its market share because its main actors are failing to properly communicate the key qualities of environmental sustainability and artisanal cod production to concerned Spanish consumers, as well as in the adoption of the place‐related attributes that still shape consumer preferences in Spain.
