Toward Hybrid Modeling and Automatic Planimetry for Graphic Documentation of the Archaeological Heritage: The Cortina Family Pantheon in the Cemetery of Valencia

ABSTRACT

The current trend toward the hybrid methodology of combining terrestrial laser scanner (TLS) with close-range and UAV-assisted photogrammetry is becoming the most effective method for the complete capture of archaeological sites. In this article, we consider three objectives in this regard: first, to check an integration procedure, based on different capture techniques, to obtain the best possible complete digital model in different situations related to size, lighting, and occlusions. Second, a “laser scanning with the help of photogrammetry” strategy for the operation with the different data sources, which allows to adapt the processes of photogrammetric orientation, cloud registration, and automatic texturing, to the characteristics of each capture model. Finally, to present the digital edition of these models through automatic technical projections and realistic visualizations, to show their ability to interpret their geometry or share their knowledge, respectively.     

Patterns of Resource Use and Isotopic Niche Overlap Among Guanaco (Lama guanicoe), Pampas Deer (Ozotoceros bezoarticus) and Marsh Deer (Blastocerus dichotomus) in the Pampas. Ecological,Paleoenvironmental and Archaeological Implications

ABSTRACT

In this paper, we analyze the isotopic niche and resource use of the guanaco (Lama guanicoe), pampas deer (Ozotoceros bezoarticus) and marsh deer (Blastocerus dichotomus) on the temperate plain of the northern Pampa region in the southeast of South America. The measured stable isotope compositions in bone tissue are δ¹³C, δ¹⁵N and δ¹⁸O. All the analyzed samples were recovered from different archaeological sites from the late Holocene. According to the results, the guanaco was strictly confined to the Pampa plain environment, developing a broad niche based on C₃ plants and a variable contribution of C₄ grasses within a grazing trend. The pampas deer preferentially used the Pampa plain, but also the prairies on the borders of the wetland, showing eurioic characteristics and a narrower niche based on C₃ plants. In turn, the marsh deer was strictly confined to wetland environments, developing a C₃ diet–base, within a narrow isotopic niche and stenoic characteristics. The three mammals showed a wide range of intraspecific variability, which was a key factor in their adaptability to spatial and temporal changes in the vegetation coverage. In fact, the temporal trends of their isotopic values were concurrent with the major climatic variations of the Holocene. Differences in the correlations between the values of both carbon sources in both deer species compared with the guanaco suggest a distinct chemical composition of their diet and/or differences in the allocation of nutrients. The isotopic values of nitrogen and spacing of the carbon sources in guanaco (pseudoruminant) and both deer species (ruminants) show no significant differences between them, thus establishing the values for local large herbivores. Significant correlations between δ¹³C and δ¹⁵N were found in the guanaco and marsh deer. The regional and extra–regional variability in the guanaco's δ¹³C_collagen and δ¹⁵N probably reflect the clinal variations in the vegetation coverage and the amount of rainfall. The collagen isotope values in the guanaco throughout the entire Holocene show that the humid Pampa would have shifted between being a more recurrent mesic and temperate plain with minor phases of dry–mesic conditions like during the Little Ice Age, and a humid and warm one at the peaks of the Holocene Thermal Maximum and the Medieval Climatic Anomaly. The guanaco and the pampas deer adapted to all the climatic changes that happened on the humid Pampa until the biological invasions of large European mammals changed the herbivores’ guild composition of this vast plain, pushing them into peripheral habitats due to competition. The within–species variability in isotopic signals through time and space make it necessary to carry out adequate sampling before reconstructing the diets of local past populations.     

Agglomeration,foreign firms and firm exit in regions under transition: the increasing importance of related variety in Hungary

ABSTRACT

Related variety of economic activities is widely recognized to induce regional development; however, it is not clear how this mechanism takes place in regions that go through major structural and institutional transformation. Furthermore, foreign direct investment (FDI) is typically a major source of structural change in these areas; and we still need a better understanding on how foreign-owned (foreign) firms affect the dynamics of domestic-owned (domestic) companies. For these reasons we analyse firm-level exit in Hungarian city regions between 1996 and 2011, over the late post-socialist transition in manufacturing industries, focusing on the difference between foreign and domestic firms. Introducing ownership into the related variety calculation, we estimate the probability of firm exit with the region-level related variety calculated separately for foreign and domestic firms. Our results suggest that related variety of foreign firms decreases the probability of domestic firm exit earlier during the economic transition compared to the related variety of domestic firms. This finding supports the idea that FDI plays a formative role in regions under transition, and shows that domestic firms benefit from being in agglomerations where foreign firms are technologically related to each other.     

The liminality in popular festivals: identity,belonging and hedonism as values of tourist satisfaction

Abstract

A Festa do Boi is a festive celebration linked to the Catholic liturgical calendar, which is celebrated in Allariz (Galicia-Spain). This festival reappears in the 1980s and like other popular festivals, it collects traditional elements and re-builds them into a new festive ritual, more in line with the new temporal and spatial configuration of the late 20th century. They are festivals in which tradition is combined, in representation of the local community, and the tourist approach (Prats, 1997 Prats, L. L. (1997). Antropología y patrimonio. Madrid: Alianza. [Google Scholar]). This event can be analysed as a spontaneous communitas (Turner, 1974a Turner, V. (1974a). Dramas, fields and metaphors. New York: Cornell University Press. [Google Scholar]), a happening between hosts and guests (Smith, 1992 Smith, V. L. (1992). Anfitriones e invitados (Turismo y sociedad). Madrid: Endymion. [Google Scholar]), where the liminal space can be occupied by tourists as ‘others’ necessary for the identification of ‘ourselves’. The participation of tourists in the festive ritual is carried out from two liminal positions: an unstable state because their daily life has been broken by the movement and involvement required in the festivals with the role of equals, but different. Both actors are required for the exaltation of collective identity. The level of satisfaction of tourists with the liminal experience based on the feeling of belonging and identification with the host community and the hedonistic perception, to provide a more holistic view of the festive ritual. A self-administered on-site survey was conducted on 393 tourists attending the 700th edition of A Festa do Boi in Allariz (Spain). The results suggest that hedonism acts as a precedent for satisfaction evaluation, and satisfaction evaluation for the attendees´ future intentions. In addition, the liminal experience has a two-dimensional structure composed of the individual changes experienced and of the festive ritual.     

Increasing returns to scale in the towns of early Tudor England

Abstract

Urban agglomeration economies make cities central to theories of modern economic growth. There is historical evidence for the presence of Smithian growth and agglomeration effects in English towns c.1450-1670, but seminal assessments deny the presence of agglomeration effects and productivity gains to Early Modern English towns. This study evaluates the presence of increasing returns to scale (IRS) in aggregate urban economic outputs—the empirical signature of feedbacks between Smithian growth and agglomeration effects—among the towns of 16th century England. To do so, we test a model from settlement scaling theory against the 1524/5 Lay Subsidy returns. Analysis of these data indicates that Tudor towns exhibited IRS—a finding that is robust to alternative interpretations of the data. IRS holds even for the smallest towns in our sample, suggesting the absence of town size thresholds for the emergence of agglomeration effects. Spatial patterning of scaling residuals further suggests regional demand-side interactions with Smithian-agglomeration feedbacks. These findings suggest the presence of agglomeration effects and Smithian growth in pre-industrial English towns. This begs us to reconsider the economic performance of Early Modern English towns, and suggests that the qualitative economic dynamics of contemporary cities may be applicable to premodern settlements in general.     

A new,extraordinary ‘damselfly-like’ Odonatoptera from the Pennsylvanian of the Avion locality in Pas-de-Calais,France (Insecta: ‘Exopterygota’)

Nel, A., Roques, P., Prokop, J., & Garrouste, R., 11 September 2018. A new, extraordinary ‘damselfly-like’ Odonatoptera from the Pennsylvanian of the Avion locality in Pas-de-Calais, France (Insecta: ‘Exopterygota’). Alcheringa 43, 241–245. ISSN 0311-5518.

Enigmaptera magnifica gen. et sp. nov., type genus and species of the new odonatopteran family Enigmapteridae, is described from the Moscovian of Avion (northern France). It is the sister group of the major clade Neodonatoptera, placed together in the new clade Paneodonatoptera. Its wing venation has characters never found in other Odonatoptera. It is a further case of convergent wing petiolation in this superorder. Enigmaptera magnifica, like the protozygopteran Jacquesoudardia magnifica from the same outcrop, probably lived like the extant damselflies along the shores of lakes and rivers, hunting the small insects found in the same deposits. These discoveries show that very small insects were significant elements of the entomofaunal diversity and trophic chains of the Late Carboniferous ecosystems.

An extremely large saber-tooth cat skull from Uruguay (late Pleistocene–early Holocene,Dolores Formation): body size and paleobiological implications

Abstract

Among the three recognized species of Smilodon, S. populator is the largest in size and has the widest distribution across South America. The present contribution describes an almost complete skull assigned to the aforementioned felid. The material was recovered from sediments of the Dolores Formation (Lujanian Stage/Age) from the southern part of Uruguay. This specimen is remarkable for its unusual craniodental measurements, indicating that it is one of the largest known specimens of the genus. Estimates of body mass indicate that this individual weighed over 400?kg. In addition, maximum prey size estimation greatly surpasses 1 t and approach nearly 3 t. Based on this, aspects of the paleobiology and paleoecology of S. populator are discussed. Undoubtedly, this kind of carnivorous mammal was at the top of the food chain, with clear adaptations for feeding upon the largest available herbivores, which potentially includes several megafaunal mammal species found in South America during the late Pleistocene.

Diplomacy in a Global Early Modernity: The Ambiguity of Sovereignty

Abstract

This is a concluding comment on the chapters of this special issue. After a discussion of the articles, we will take a closer look at the new view of European diplomacy and foreign relations. The historiographical change regarding early modern foreign relations has fundamentally altered the way we interpret the roles, the agencies and the loyalties of early modern envoys. Taking the conclusions of this research into account, we ask if diplomatic actors of the ancient regime differed distinctly from their Asian counterparts at all. Then, as a final point, we examine how fundamental changes in the Sattelzeit–particularly in Europe, but also in the context of global power relations–affected intercultural diplomacy.
