This article describes ethnographic research involving street children and child labor in urban Honduras. It is set in a context of deteriorating social, political, and economic conditions that has created an increase in child labor. However, the research findings have delineated that a growing number of children are choosing to work and live on the street to escape extreme poverty and hunger in their familial households. Despite the multi-local spaces they inhabit, they have been able to create unique non-kin relations while often maintaining family based linkages. This study, undertaken in two centers for boys in Tegucigalpa and Comayagua, Honduras analyzes the contextual dynamics and decision-making processes of Honduran youth regarding work and living arrangements in urban spaces.  相似文献

Postcolonial archaeologies in Africa are engaged in a variety of agendas including the decolonization of everyday practices in the field and in the classroom. Postcolonial theory, concerned with issues of power and the Other, is increasingly being invoked to examine how archaeologists conduct their field research and how archaeology is used to dismantle essentialized histories—the metanarratives that arose in the colonial as well as the postcolonial era. Easily misunderstood, however, is the passion expressed by some African archaeologists who are voicing their own views while simultaneously trying to free themselves from dominating “expert” voices. These occurrences create tensions in archaeological discourse that are a natural part of decolonizing archaeology, joining other forms of disenchantment, particularly the disenchantments arising in contemporary African communities about social services, civil society, and human rights. Archaeologists are also implicated in disenchantments as they conduct investigations in the midst of people who may be without water or are suffering from HIV/AIDS—conditions that starkly contrast with their own comfortable lives. We may also need to reconsider how to deal with states that see archaeological research as contrary to nation building. This essay responds to some current misunderstandings that have arisen over these and related issues.  相似文献

Around the margins of Asmara, Eritrea, hundreds of sites dating to the early and mid-first millennium BC have been documented. They range from single family dwellings to small and large hamlets, small and large villages, and small towns. We call these Ancient Ona sites, using the Tigrinya term for ruin. Our findings testify to significant subsistence, ritual, and economic variation within a region of 12 by 17 km: (1) different subsistence strategies in the well-watered, open basin to the west of Asmara (emmer wheat, barley; cattle) compared to the uplands north and east of Asmara (lentil, teff; goats/sheep); (2) ritual events, marked by stone bulls' heads and a huge ash deposit at Sembel Kushet, that brought people together in rites of passage and intensification during Meskel-like ceremonies, including ritual exchange; and (3) the exploitation of gold north of Asmara among heterarchically organized communities that exchanged specialized products within this region.  相似文献

Archaeological sites dating from the Preboreal are of special interest since they mark the turning point in the transition between the cultures of the Late Pleistocene and the Holocene. In spite of their relevance only few sites in the Western and Central European Plain have become known, thus providing an inhomogeneous basis for further hypotheses. In particular, sites in the widespread aeolian landscapes have been neglected for a long time due to their uncertain genesis, dating problems and obviously insufficient preservation. Our investigations of the Haverbeck site, situated in sandy aeolian substrate, seek to enhance knowledge about the Preboreal Mesolithic. The well-preserved archaeological spatial, technological and functional patterns and the geoarchaeological site formation were studied. Sedimentological and palaeopedological analyses, supported by 14C and OSL dating results, revealed that artefacts were deposited during the Preboreal on sands which had accumulated during the Younger Dryas and were reactivated in subsequent periods (Atlantic, Subboreal, Subatlantic). In spite of these processes, the artefacts remained unimpaired in their relative horizontal positions, enabling spatial analyses, which show a zonal differentiation and a prevalence of retooling and replacing activities. These results offer an insight into spatial and functional differentiations of the local Early Mesolithic subsistence, evidently including particular places for gathering and processing raw material. A comparison between the microlithic spectrum left behind and the number of points produced as concluded from the microburins indicates a greater typological differentiation than previously assumed for the Early Mesolithic. The remarkable variability of scraper forms obviously intentionally abandoned in a high number and replaced by new tools emphasizes the strong influence of functional elements on the typological assemblage composition. It is suggested that Early Mesolithic assemblages could display rather functional requirements or tasks performed than significant chronological or regional influences.  相似文献

This article discusses the Lisbon Agenda from the perspective of entrepreneurship policy. After a brief overview of the events leading up to the development of the Lisbon Agenda, the authors describe the goals and content of this policy framework as well as of the structural funds. Using examples of initiatives towards implementation at the local level, the authors illustrate the necessity to promote entrepreneurship in order to foster economic growth in communities and regions. We assess how the new European growth policy became translated into an action plan realized through structural funds and community initiatives and demonstrate that a greater focus on entrepreneurship policy could strengthen the Lisbon Strategy and aid in the achievement of its goals.  相似文献

This paper seeks to understand how recent social, economic and institutional developments have affected the land use planning tools and instruments that German planners have at their disposal. Although traditional planning practice was focused on the equitable distribution of services and infrastructure and managing growth within a highly structured plan approval process, planning tools at both the local and regional level have become increasingly concerned with enhancing local or regional competitiveness, primarily through the inclusion of a greater number of actors in formulating land use decisions. I argue, however, that despite these changes, the overall institutional framework, which revolves around legal and procedural concerns such as the plan approval process or the granting of building permission, has generally remained unaffected, and a significant gap exists, particularly at the regional level, between the strategic goals of regional governance and actual land use planning tools.  相似文献
