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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

In this paper, we present the results of an experimental approach developed to study the macroscopic and microbiological alteration of bird and small mammal bones buried under a Cerrado biome. The first experiment evaluated the macroscopic alteration of cooked and fresh carcasses buried through the dry and rainy seasons. The second experiment analyzed the mycobiota associated to the decomposition of a complete bird that remained buried for almost a year. Results show that in tropical forest environments: 1) bone structure and pre-taphonomic factors determine its differential alteration by biochemical processes; 2) fungal populations associated to the decomposition of animal remains depend on soil chemistry and ecological dynamics; 3) even in a corrosive environment, bird bones are more capable of surviving to several mycological decomposition steps.  相似文献

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.

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”.  相似文献

While the land use-street network nexus is well acknowledged, evidence for the one-way impacts of land-use patterns on street accessibility is still inadequate. The measurements of land-use patterns and street accessibility lack systematic knowledge. Their empirical correlations also lack geographical variability, constraining site-specific land-use practices. Therefore, this study overcame the aforementioned limitations by examining the two-level spatial models to formulate accessibility-oriented land plans, using a well-developed Chinese city as an example. Firstly, two landscape metrics—Euclidean Nearest-Neighbor Distance (ENN) and Similarity Index (SIMI)—were used to quantify the intra- and inter-land-use configurations, respectively. Both city-level and local accessibility were measured using spatial design network analysis. Performing both ordinary least squares (OLS) and geographically weighted regression (GWR) models, results identified the statistically significant effects of inter-land-use patterns on two-level street accessibility. An exception was that land-use configurations within residential and industrial regions were irrelevant to street accessibility. We also found GWR was a better-fitting model than OLS when estimating locally-varied accessibility, suggesting hierarchical multiscale land-use planning. Overall, locally heterogeneous evidence in this study can substantialize land use-street network interactions and support the decision-making and implementation of place-specific accessibility-oriented land use.  相似文献

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.  相似文献
