Sharks in the lagoon? Fishing exploitation at the Neolithic site of Suwayh 1 (Ash Sharqiyah region,Arabian Sea,Sultanate of Oman)

The study of the fish bones from the Neolithic shell midden of Suwayh 1, excavated in the 2000s, identified a total of 1060 identifiable fish bones, from 23 families, 33 genera and 28 different species. Radiocarbon dating demonstrates that the sites date to the early 6th to mid 5th millennium BC. The results follow an eight-phase chronology highlighted by an earlier malacological study. The most important taxa were the Carcharhinidae (requiem shark), Rhinopteridae (cownose rays), Sparoidea (Sparidae and Lethrinidae: sea breams and emperors) and Ariidae (sea catfishes). The results of the fish study show that the Suwayh lagoon must have gradually opened up to the sea and been populated with mangroves. The unique presence of so many sharks at this site seems to indicate that the inhabitants had a special interest in shark fishing and that their location was ideal for this specialised activity. Two types of fishing nets and hooks have been discovered, which require the use of different fishing techniques.     

What makes people stay in or leave shrinking cities? An empirical study from Portugal

The attractiveness of cities as places to live determines population movements into or out of them. Understanding the appealing features is fundamental to local governments, particularly for cities facing population decline. Pull and push attributes can include economic aspects, the availability of amenities and psychological constructs, initiating a discussion around which factors are more relevant for migration. However, such discussion has been underexplored in studies of shrinking cities. In the present study, we contribute to the discussion by identifying pull and push factors in Portuguese shrinking cities. Data were collected using a face-to-face questionnaire of 701 residents in four shrinking cities: Oporto, Barreiro, Peso da Régua and Moura. Factor analysis and automatic linear modelling were used to analyse the data. Our results show that the economic activity is the most relevant feature for retaining residents. However, characteristics specific to each city, related to heritage and natural beauty, are also shown to influence a city’s attractiveness. The cause of population shrinkage was also found to influence residents’ assessments of the pull and push attributes of each city. Furthermore, the results show the relevance of social ties and of place attachment to inhabitants’ intention to continue living in their city of residence.     

The Evolution of Population Distribution on the Iberian Peninsula: A Transnational Approach (1877–2001)

Abstract

Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.     

Muscles,Nerves, and Sex: The Contradictions of the Medical Approach to Female Bodies in Movement in France, 1847–1914

From the early nineteenth century in France, the treatment of hysteria was connected to both physical and moral development. As a result, therapeutic treatments envisaged by medical practitioners were influenced by and related to the formulation of precepts of medical gymnastics. This article considers how ‘physical education’ for women became part of medical discourse, specifically the elaboration of ‘body treatment’ as a remedy against nervous disorders including hysteria. From the Second Republic (1848) to the years of the belle epoque (1914), the discourse concerning the medical cause of ‘hysterical madness’ is marked by the progressive discrediting of reflections that located the causes of pathology in the genitals. However, the shaping of a neuro‐cerebral etiology did not fully replace discussions of the relationship between hysteria, female bodies and the uterus. While the current historiography emphasises the participation of doctors in the production and legitimation of physical exercises in the nineteenth century, some aspects of this process are not yet fully explored. We examine the ambivalences of medical discourse, between the rhetoric of the eternally wounded woman and the need to develop women's abilities (intellectual, moral, and physical) to ensure healthy children. And despite the shadows that still obscure the etiology of nervous disorders, there is, in our period, a genuine dynamic favouring experimental therapeutics. The ‘movement disorders’, such as chorea, hysteria or neurasthenia, were handled by increasingly well‐established regimes utilising physical exercise. The introduction of gymnastics in the hospital played a fundamental role in this process; it enabled experimentation and lent legitimacy to physical exercise as therapy.     

Elasmosaurs (Sauropterygia,Plesiosauria) from the La Colonia Formation (Campanian–Maastrichtian), Argentina

O’Gorman, J.P., Salgado, L., Varela, J., & Parras, A., 2013. Elasmosaurs (Sauropterygia, Plesiosauria) from the La Colonia Formation (Campanian–Maastrichtian), Argentina. Alcheringa 37, 257–265. ISSN 0311-5518.

Elasmosaur postcranial remains from the La Colonia Formation (Campanian–Maastrichtian), Chubut Province, Patagonia, Argentina, are described. The new material has small dimensions and caudal vertebrae with parapophyses strongly projected laterally—characters shared with some Elasmosauridae indet. from the coeval Allen Formation, Río Negro Province, Argentina. These features reinforce the similarities between the plesiosaur faunas to the north and south of the Somún Curá Plateau. The small size of these elasmosaurs may be palaeoecologically related to the marginal marine depositional environment of the sedimentary host rocks.

International R&D Cooperation between Low-tech SMEs: The Role of Cultural and Geographical Proximity

Although there is a considerable amount of empirical evidence on inter-firm collaborations within technology-based industries, there are only a few works focussing on R&D cooperation by low-tech firms, especially small and medium-sized enterprises (SMEs). Providing further and new evidence based on a recently built database of CRAFT projects, this study analyses the relationship between technology and proximity in international R&D networks using HOMALS and statistical cluster techniques. The resulting typology of international cooperative R&D projects highlights that successful international cooperative R&D projects are both culturally/geographically closer and distant. Moreover, and quite interestingly, geographically distant projects are technologically more advanced whereas those located near each other are essentially low-tech. Such evidence is likely to reflect the tacit-codified knowledge debate boosted recently by the information and communication technology (ICT) “revolution” emphasized by the prophets of the “Death of Distance” and the “End of Geography”.     

Civilization and Barbarism: When Barbarism Builds Cities

Around the mid-nineteenth century, D. F. Sarmiento introduced in Argentine literature the duality of “civilization and barbarism,” assuming that it was, at that time, an inescapable model in the analysis of society. Early in the 1880s, when the “conquest of the desert” came to an end and conflicts between city inhabitants and their urbanistic and “civilizing” urban plannings, vis-à-vis the rural populations that assumedly resisted change, worsened, the model acquired a new meaning. Taking one particular case of analysis, the foundation of the city of La Plata in lands owned by the Estancia Iraola, this paper uses archaeology to explore the limitations and falsehoods of such duality, jointly with the assumption of a simplistic relation of determinism between an environment and a particular human group.     

THE ACEHÚCHE GOLD TORC: GOLD AND SACRED LAND ON THE SHORES OF THE TAGUS RIVER (CÁCERES,WESTERN SPAIN)

This article describes the important discovery of a Late Bronze Age gold torc that was unearthed in a field of Acehúche (Cáceres, Spain). It was buried underneath some rocks at a site near a river crossing over the Tagus river. In its immediate vicinity, archaeological remains dating from the Copper Age to the Late Bronze Age have been found, which indicates the long use of this crossing. Until recently here, there existed a ferry and a chapel; and the place went by the toponym of the Dehesa de San Cristóbal. Legend too has it that the water from the river had curative properties. All of these components have maintained the sacred nature of the spot, otherwise transformed over the course of time, and reflect an earlier sacred landscape with quite ancient roots.     

Soluble Salts Amplify the Effect of Small Heterogeneities in the Structure of Porous Building Materials During Drying

Salt crystallization is a major cause of degradation in old buildings. One of the issues that stills need clarification is regarding the influence of the salts on the capillary absorption and subsequent drying of porous building materials. This article presents an experimental study that included capillary absorption and evaporative drying tests on two types of material (lime mortar and ceramic brick) using pure water or saturated solutions of six salts (sodium chloride, sodium sulfate, sodium nitrate, sodium carbonate, potassium nitrate, or potassium carbonate). The results of capillary absorption agree only roughly with the linear relationship, predicted by theory, between sorptivity and the square root of the ratio between viscosity η and surface tension σ of the solution (σ/η)^1/2. This poor agreement is probably due to material heterogeneity. The drying dynamics was regular and showed little dispersion between specimens, but only for the uncontaminated materials. Indeed, the drying dynamics of the salt contaminated materials was often irregular or diverged among similar specimens, and the same happened with their salt decay patterns. The main conclusion is that soluble salts can amplify the effects on drying of the small structural heterogeneities that porous building materials normally depict.
