Ethnoarchaeological research combined with morphological analysis of modern and ancient grinding stones was completed in 2013 and 2014 as part of the Eastern Tigrai Archaeological Project (ETAP), based in the Gulo Makeda region of northern Ethiopia. Research focused on investigating the cultural context of grinding, grinding stone morphology, and use-surface area employing low power use-wear analysis of grinding surfaces. In the Gulo Makeda region today, men manufacture grinding stones and women use them in food processing for many hours per day. While grinding, relationships are formed and maintained with other women, and archaeological evidence suggests that women were grinding together in the past. It was discovered through interviews that distinctive grinding surfaces are preferred for processing different cereals based on grain size. Rough surfaces are used to process larger grains such as imported Near Eastern barley (Hordeum vulgare), wheat (Triticum spp.), maize (Zea mays), and the African domesticate sorghum (Sorghum bicolor), while fine/smooth surfaces are used for smaller, locally domesticated African grains including finger millet (Eleusine coracana) and t’ef (Eragrostis tef). Comparing ethnoarchaeological data with evidence of different use-surfaces on ancient Mezber grinding stones suggests that both locally domesticated and imported grains have been processed in the region for thousands of years. Interpretations are made about the use of grinding stones in the past through analogy, supported by evidence of ancient stone tool morphology and surface wear. The archaeological record at the pre-Aksumite site of Mezber indicates that grinding stone sizes have changed through time, with larger grinding surface areas likely reflecting the need for the production of greater amounts of flour.  相似文献

This paper aims to contribute to the debate on the determinants of differentials in firms’ productivity. We test the hypothesis that macro factors, especially the quality of local institutions, play a central role in explaining firm productivity in Italy. To this end, we construct measures of Total Factor Productivity (TFP) for about 4,000 firms by means of different estimation techniques, and a province‐level index of institutional quality. Then, we estimate the relationship between institutional quality and firm‐level TFP. Our results show that the existence of better local institutions might help firms to become more productive.  相似文献

The development of Viagra in the late 1990s ushered in a new age of conversation about sex and sexuality, as men's bodily abilities were put on display for all to discuss. In 2005, the video-sharing technology YouTube was launched. Taken together, these technological innovations – both biomedical and representational – have produced debate around sex, sexualized and gendered bodies, and sexual health. This article interrogates Viagra-related representations posted on YouTube and analyzes sexuopharmaceuticals as a set of intertextualities that create space for both normative discourses and social critiques. Three analytic themes illustrate how Viagra-related YouTube videos (1) reinforce a regime of self-care within a wider context of individualized responsibility for one's sexual health, (2) highlight the values attached to the pharmasexed gendered body for men and women in the age of Viagra, and (3) provide disruptions, in the form of criticism, to the assumption that healthy bodies and relationships need pharmasexual enhancement. The article concludes by suggesting that social networking sites such as YouTube are managed public spaces through which one can interrogate the intertextualities that link discourses related to bodies and sexual health to the virtual and material spaces of everyday life.  相似文献

House-building with wood has a long tradition in Austria. In this study, 47 houses from the Austrian Alps and the alpine foothills were analyzed. Dendrochronology was used to date the houses and to extract further information as construction phases within one building and time needed for harvesting. The construction dates range between 1452 and 1934. The focus was set on log constructions and in particular on wooden log walls. All wooden walls were made of softwood, clearly dominated by Norway spruce (Picea abies). A remarkable decline in the utilization of spruce wood as construction timber was found during the 19th century, which might be due to the high charcoal production at that time. By analyzing age, wood species, time of harvesting and way of processing, knowledge about wood utilization and historical forest management can be regained. Furthermore, some social and economical background of the farmers can be lifted. Technical dates as wall thickness and total wood volume required to build a residential building is provided.  相似文献

In recent decades, indigenous populations have become the subjects and agents of development in national and international multicultural policy that acknowledges poverty among indigenous peoples and their historic marginalization from power over development. Although the impact of these legal and programmatic efforts is growing, one persistent axis of disadvantage, male–female difference, is rarely taken into account in ethno-development policy and practice. This article argues that assumptions that inform policy related to indigenous women fail to engage with indigenous women's development concerns. The institutional separation between gender and development policy (GAD) and multiculturalism means that provisions for gender in multicultural policies are inadequate, and ethnic rights in GAD policies are invisible. Drawing on post-colonial feminism, the paper examines ethnicity and gender as interlocking systems that structure indigenous women's development experiences. These arguments are illustrated in relation to the case of the Tsáchila ethno-cultural group in the South American country of Ecuador.  相似文献

First Nations peoples are revitalising diverse cultural fire practices and knowledge. Institutional and societal recognition of these practices is growing. Yet there has been little academic research on these fire practices in south-east Australia, let alone research led by Aboriginal people. We are a group of Indigenous and settler academics, practitioners, and experts focused on cultural fire management in the Victorian Loddon Mallee region. Using interviews and workshops, we facilitated knowledge sharing and discussion. In this paper, we describe three practice-oriented principles to develop and maintain collaborations across Aboriginal groups, researchers, and government in the Indigenous-led revitalisation of fire on Country: relationships (creating reciprocity and trust), Country (working with place and people), and power (acknowledging structures and values). Collaborations based on these principles will be unique to each temporal, social, cultural, and geographic context. Considering our findings, we acknowledge the challenges that exist and the opportunities that emerge to constructively hold space to grow genuinely collaborative research that creates change. We suggest that the principles we identify can be applied by anyone wanting to form genuine collaborations around the world as the need for social–ecological justice grows.  相似文献
