Early Miocene bivalves from the Cape Melville Formation,King George Island,West Antarctica

Seven species of marine bivalves, including six new taxa, are described from the Cape early Miocene Melville Formation which crops out on the Melville Peninsula, King George Island, West Antarctica. The bivalve assemblage includes representatives of the families Nuculidae, Ennucula frigida sp. nov., E. musculosa sp. nov.; Malletidae, Neilo (Neilo) rongelii sp. nov.; Sareptidae, Yoldia peninsularis sp. nov.; Limopsidae, Limopsis psimolis sp. nov.; Hiatellidae, Panopea (Panopea) sp. cf. P. regularis; and Pholadomyoida (Periploma acuta sp. nov.). Species studied come from four sedimentary sections measured in the upper part of the unit. Detailed morphologic features of nucloid and arcoid species are exceptionally well preserved and allow for the first time reconstruction of muscle insertions as well as dentition patterns of Cenozoic taxa. Known geological distribution of the species is in agreement with the early Miocene age assigned to the Cape Melville Formation. The bivalve fauna from Cape Melville Formation is the best known from Antarctic Miocene rocks, a time of complex geologic, paleogeographic and paleoclimatic changes in the continent. The new fauna introduces new taxonomic and palaeogeographic data that bear on the question of opening of sea gateways and distribution of Cenozoic biota around Antarctica.     

A TURNING POINT IN THEORY OF HISTORY: THE PLACE OF HAYDEN WHITE IN THE HISTORY OF METAHISTORY

This article intends to place Hayden White's reflection on the basic principles of meaning-construction in history into the historical context of modern historical studies. It first presents the self-understanding of professional historians in which they emphasize the academic (wissenschaftlichen) character of the discipline. In this way of reflection, the traditional (premodern) interpretation of history as a part of rhetoric was pushed back and replaced by methodological argumentation about the rules of research (with an emphasis on source critique). Historiography, or the presentation of the results of research in a narrative form, was not completely neglected, but was not widely recognized. After the analytical insight into the narrative form of historical knowledge, significant discussion of the principles of historical thinking dramatically changed from the issue of research to that of representation (historiography). Hayden White's Metahistory (1973) marked this change paradigmatically. It turned the shift from rhetoric to science in its contrary direction: a new turn to rhetoric was proclaimed. This new anti-turn set off a hitherto unanswered question as to how research methodology should be treated. Source critique was not refuted but did not attract significant attention. The research procedure of interpretation, in contrast, was met by a new understanding and interest: it was identified as representation by the linguistic procedures of meaning-construction. Its role as a part of historical method, however, was completely ignored. The article ends with a still unresolved problem of metahistory, namely the relationship between interpretation and representation. They are not identical, but are closely related. Their synthesis and their differences have to be systematically inquired into and reflected upon if metahistory is to step forward and engage in this task. Then the merits of White's return to rhetoric will be appreciated as well as its one-sidedness criticized, before a further step is taken.     

The Idea of the Social Contract in the History of ‘Agreementism’

One of the recurrent motifs in political thought is the idea of the social contract, according to which a society, a government, or moral principles depend for their existence on agreements between voluntary agents. This association between the social contract and “agreementism” implies that there is nothing about the terminology of contracts that distinguishes it from that of other types of agreements constitutive of normativity. This essay tests this assumption by surveying the terminology of the social contract and by proposing two hypotheses. The first is that all attempts at analysing the idea of the social contract require a formal conceptual frame of reference that is distinguishable from agreementism. The second is that social contract theories can be grouped into four trends, even if the authors of each of these trends are unable to form a coherent body of doctrine. These trends are the Iberian Catholic version of the Counter-Reformation; the Protestant individualist trend of the Enlightenment; the quasi-dialectical trend of the radical Enlightenment; and the contemporary trend of public morality.     

The smelting quarter of Valencina de la Concepción (Seville,Spain): the specialised copper industry in a political centre of the Guadalquivir Valley during the Third millennium BC (2750–2500 BC)

The first specialized copper industry of the Iberian Peninsula was developed at the start of the Third millennium BC with the appearance of mining-metallurgical settlements in its main mining district (the Pyrite Belt of the south-western). Between 2750 and 2500 BC, however, and right at the centre of the Guadalquivir Valley, the great farming settlements that ranked the territory developed a new level of metallurgic intensification with the creation of the first industrial quarters. As a way of explaining this new situation, we present the results of the systematic research (microspatial analysis; radiocarbon dating; petrologic, geochemical, metallographic and isotopic study of minerals, slag and products, …) carried out in one of them, the one developed in the main and largest political centre of the Guadalquivir Valley during the first half of the Third millennium BC: Valencina de la Concepción (Seville, Spain).     

Spatial and temporal dynamics of the urban heat island effect in a small Brazilian city

This study examined the spatial and temporal patterns of the canopy layer urban heat islands (UHI_UCL) in a small city in southeastern Brazil using the local climate zone (LCZ) system. We analysed the influence of weather conditions, LCZs characteristics, and local surface relief on the UHI_UCL magnitudes. Mobile traverses were used to measure air temperatures during representative nights of wet and dry seasons. Daily maximum magnitudes were observed in compact classes (LCZs 3 and 7) under ideal weather conditions (dry, clear skies, and calm) and higher anthropogenic heat release (weekdays). Seasonal effects on LCZ thermal differences were negligible. The peripheral landscapes were warmer than the city centre in both seasons. Among the warmer areas in the city, magnitudes in compact LCZs 3 and 7 were consistently higher than in LCZ 6. In general, representative sites of the main ‘built’ LCZs in the study area exhibit similar inter-zone temperature patterns to those reported for cities of different sizes from tropical and midlatitude regions. Thermal contrasts of ΔT_{LCZ 3 − D} in the study area reveal significant evidence that small cities can have as strong heat islands as bigger cities. These findings highlight the importance of the LCZ system to identify the main controlling factors driving such thermal differences and the need to extend the application of this approach in other South American cities to yield systematic data of UHI_UCL for urban planning given the coming challenges of climate change over the region.     

Iron Age Saunas of Northern Portugal: State of the Art and Research Perspectives

Special buildings used as saunas have been found in certain large hillforts in the north of Portugal and in the Cantabrian coastal area of Asturias and Galicia in Spain. The principal aim of this study is to highlight the importance of these buildings in the archaeology and art of the European Iron Age, where they are very rarely mentioned. Two approaches are developed: in Parts 1 and 2, we explain the structure of the buildings, their function, and the current debate surrounding their dating. In Parts 3 and 4, further analyses are developed on their position in the landscape, associating the saunas with the public life of the hillforts, and on the decorative structure of the pedras formosas (‘beautiful stones’) found in some of them, and their relation to certain artistic trends in so‐called Celtic art.
