A number of key events occur in Africa during the middle Pleistocene including the disappearance of the Acheulian, the appearance of the Middle Stone Age, and the emergence of modern Homo sapiens. However, little is known about either the fossil or behavioral record for this critical time period. Excavation was undertaken at two middle Pleistocene archaeological sites, GnJh 42 and GnJh 50. These sites are located in close proximity to a large fresh water spring, a focal point on the landscape that supported a diverse plant and animal community. The lithic assemblages are dominated by flakes and cores, and lack all formal tools. However, the oldest evidence for systematic blade production can be found at these sites, indicating that important technological innovations were appearing at this time. Tendency to focus on the presence or absence of formal tools, means that assemblages of this age, lacking diagnostic artifacts, are typically subsumed within the Acheulian technocomplex. This practice disguises actual patterns of innovation and technological evolution. It is critical not to overlook this, as small-scale technological innovation allowed for more behavioral flexibility in response to rapid environmental change in a arid, mosaic environment. 相似文献

Governments around the world are developing smart city projects, with the aim to realize diverse goals of increased efficiency, sustainability, citizen engagement, and improved delivery of services. The processes through which these projects are conceptualized vary dramatically, with potential implications for how citizens are involved or engaged. This research examines the 20 finalists in the Canadian Smart Cities Challenge, a Canadian federal government contest held from 2017 to 2019 to disburse funding in support of smart city projects. We analyzed each of the finalist proposals, coding all instances of citizen engagement used to develop the proposal. A significant majority of the proposals used traditional types of citizen engagement, notably citizen meetings, round tables, and workshops, to develop their smart city plans. We also noted the use of transactional forms of citizen engagement, such as apps, and the use of social media. Despite the general rhetoric of innovation in the development of smart cities, this research finds that citizens are most commonly engaged in traditional ways. This research provides cues for governments that are developing smart city projects, placing an emphasis on the importance of the process of smart city development, and not simply the product. 相似文献

Theoretical developments in sociocultural anthropology have transformed the study of kinship. Here, we review these theoretical developments, consider their influence on bioarchaeological kinship research, and propose an alternative framework for studying relatedness in antiquity. We find that broader, more flexible conceptions of relatedness have grown increasingly prevalent in 21st-century bioarchaeology, but kinship research largely continues to emphasize methodological improvement and identification of biological kin in archaeological contexts. By approaching kinship as a multiscalar dimension of social identity, bioarchaeologists can leverage complex conceptions of relatedness with diverse types of data to gain nuanced perspectives on family-based social organization in the past. 相似文献

Significant infrastructural projects, and especially large hydroelectric dams, were envisioned and deployed by postcolonial governments to promote particular visions of industrialization, agriculture, democracy, and modernity. Newly independent states sought to annihilate formerly so-called backward and primitive landscapes and populations alike, promising to re-create both places and people as rational, economically productive entities. In this article, we re-examine such narratives as they related to Ghana's Volta River Project (VRP). Relying on archival and media sources between the 1950s and 1960s, we interrogate the Ghanaian state's pursuit of the VRP from a perspective rooted firmly in cultural geography and pay careful attention to the issues of population displacement/resettlement and landscape reconfiguration that permeated all dimensions of the project. We analyze the ways in which Ghanaian leaders used the VRP to translate a particular suite of cultural, economic, and political values into material reality, utilizing the techniques of displacement and population resettlement in efforts to enroll Ghana into a modern, global, industrial economic system. As such, this article augments the body of literature examining the modernist and state-building aspects of the VRP as well as studies critiquing the various processes of development that have unfolded in West Africa since the mid-twentieth century. 相似文献
