This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.  相似文献

Current research in the Mixteca region of Mexico has revealed that Formative communities were as populous as in other Mesoamerican regions. Evidence of emerging social complexity is associated with the use of and access to luxury items of foreign style and/or manufacture. Research efforts draw from indigenous models to interpret data and investigate urbanism. Regional and environmental approaches, household studies, and ethnohistory are integrated to study ethnic diversity and the complex history of human occupation. The politics associated with cultural resource management and community archaeology in the Mixteca also are discussed.  相似文献

Trans and gender nonconforming (TGNC) people who make refugee claims in Canada negotiate a complex nexus of identity, belonging, and citizenship. Drawing on insights from TGNC refugees, immigration lawyers, and frontline workers, in this paper we examine the ways the state controls the trans body through the refugee claims process and in the process of integration into life in Canada, while also highlighting trans refugee methods of survival and resistance. What emerges is an understanding of the ways that refugees navigate the tension between gender, sexuality, and homecoming as both intimately felt and geopolitically managed. We convey TGNC refugee narratives to demonstrate how they both confirm and expand upon the existing literature on Canadian LGBTQ+ refugees. TGNC refugees' experiences at the Immigration and Refugee Board confirm insights from existing LGBTQ+ refugee studies. However, TGNC refugees' day-to-day lives differ significantly from LGB refugee lives as recounted in the literature. In TGNC refugees' attempts to access gender-affirming documentation, healthcare, housing, and income, they confront distinct systems of transgender exceptionalism, border imperialism, and racial and heteropatriarchal capitalism that limit their access to basic necessities and impact how they build home both conceptually and materially.  相似文献

Damage generated by large and small carnivores is common in many Middle Pleistocene sites. However, identifying the predator that produces the faunal accumulations is often a difficult task. In order to recognize the main type of carnivore that acts on a faunal assemblage, a combination of several characteristics should be taken into account: taxonomic and skeletal element representation, age profiles, carnivore damage (location, frequencies and dimensions of tooth-marks, bone breakage and digested bones), degree of fragmentation and frequencies of coprolites. But, adding environmental characteristics and the ethology of non-human predators/scavengers is also important. All these aspects are applied to the faunal assemblage from the TD8 level of the Gran Dolina site (Sierra de Atapuerca, Burgos, Spain). Paleomagnetic data combined with ESR and U-series place the TD8 level at the beginning of the Middle Pleistocene, specifically circa 700 kyr ago. The TD8 level contains a large faunal accumulation primarily composed of ungulate skeletal elements, and to a lesser extent carnivore remains. This assemblage is characterized by an overrepresentation of fallow deer (Dama vallonetensis), a skeletal profile biased towards cranial remains and limb bones, diversity of ages at death, a high proportion of carnivore damage and tooth-marks of large size, and an absence of human activity. According to these data, the accumulation seems to have been produced primarily by large carnivores, possibly hyenas. This observation does not rule out the possible occasional activity by other carnivores. Nevertheless, the characteristics of the TD8 assemblage do not correlate entirely with those traditionally used to define carnivore dens. In TD8, there are (1) no immature carnivore remains (remains of just one young Mosbach wolf); (2) scarce traces related to the end stages of consumption and some anatomical connexions; (3) few coprolites; (4) high proportion of adult ungulates and; (5) high quantities of whole bones and epiphyses. From this perspective, the TD8 faunal assemblage seems to correspond to a succession of carnivore occupations that allows the development of a suite of features to identify the activities of several species of predators that may have used the cave in different ways and durations. This study aims to emphasize the importance of these analyzes in order to know the behaviour of different non-human predators/scavengers in the European Middle Pleistocene sites.  相似文献

The growth of collaborative approaches to governance has resulted in increasingly complex policy and management landscapes, where actors are presented with ever‐increasing numbers of decision‐making venues they can participate in and actors they can collaborate with. Given that actors face constraints on their capacity to manage actor and venue relationships in such polycentric governance systems, we assume the marginal benefit of yet another relationship should begin to diminish at some level of engagement. Furthermore, we hypothesize that such capacity limitations are not static, but decrease as actors learn, develop skills, and formulate strategies for how to navigate complex polycentric systems more effectively. Drawing on the Ecology of Games framework, this article investigates two Swedish collaborative governance initiatives where a multitude of actors came together to address a range of different, but interrelated, policy issues and management tasks. The empirical findings suggest that actors’ capacities to successfully navigate polycentric governance arrangements increase as they gain experience and develop their networking skills. Our findings imply there is a need to balance increased complexity in polycentric systems with increased capacity, otherwise the overall effect of an ever‐increasing number of venues and actors could be collaborative fatigue and decreased abilities to address diverse governance challenges.  相似文献

There are two distinct forager-farmer adaptive regimes evidenced in the ethnographic record: an ancillary and surplus cultivation regime. Societies characterized by these different regimes define different systems for allocating time to the production of domesticated plants. Cross-cultural patterns support the proposition that two socioecological conditions are logically necessary in order for an ancillary cultivation regime to develop and persist within a population of foragers. Wild resources must be sufficiently available, and farmers who produce a surplus of crops must be available to exchange with, live with or raid to redistribute crops after an episode of crop loss. The cross-cultural presence of two empirically distinct regimes for integrating foraging and farming is a useful frame of reference for evaluating how prehistoric foragers first integrated foraging and farming activities in archaeological contexts of secondary crop acquisition. A preliminary examination indicates that the ethnographic patterns are most consistent with the interpretation that the earliest farmers to inhabit the American Southwest produced at least a minimal surplus of domesticated plants. It is postulated that the adoption of a surplus cultivation regime by a population creates the adaptive opportunity for ancillary cultivation to develop and persist on a landscape.  相似文献

In a world where large urban agglomerations are increasingly regarded by scholars and policy-makers alike as the engines of economic development, the options at the disposal of intermediate and peripheral areas are dwindling. Doing nothing is, according to the dominating theories, likely to result in a steady decline which may jeopardize their very economic viability. Adopting active measures is thus the way forward. In this paper, we argue that the main solution being proposed—interactive learning through the promotion of local agglomeration (buzz option)—may yield limited results, if at all, as it would stifle the circulation of new knowledge and lead to lock-in. By contrast, promoting interaction outside the comfort zone of geographical, cognitive, social and institutional proximity (pipeline option) is more likely to succeed in generating interactive learning and in facilitating the generation, diffusion and absorption of innovation. We illustrate this point by resorting to the case of firm innovation in Norwegian city regions.  相似文献
