A burial ground located in the Town of Colonie, NY along the Hudson River revealed fourteen individuals dated from the 17th through the early 19th centuries. Bioarchaeological analysis suggested some of these individuals were of African ancestry who had worked and died on the property owned by the prominent Schuyler family. Mitochondrial DNA (mtDNA) analysis was carried out on skeletal remains of seven adults using restriction fragment length polymorphism typing and direct sequencing of the control region to infer their origins and relatedness. Results show that none of the individuals were maternally related, with four individuals identified as African haplogroup L, one identified as Native American haplogroup X, and two identified as haplogroup M and M7. Individuals of African ancestry correlate with published mtDNA data on African Americans and their geographical origins corroborate with the various exit points during the African slave trade to New York State. Individuals identified as haplogroup M7 and M resemble lineages found in Madagascar. Historical documents suggest several hundred people were imported from Madagascar through illegal trading to New York by the end of the 17th century. This study highlights the diverse origins of the enslaved labor force in colonial New York and contributes to our understanding of African American history in the northeast.  相似文献

The study of the determinants of African defense demand is of enhanced importance because of unique security challenges, growing defense spending, and changing African Union (AU) integration. From a political geographical vantage, this study presents the first analysis of AU members' demand for defense spending, which accounts not only for members' relative locations, but also for political considerations (e.g., state failure, coups, and armed conflicts). Our analysis marries the economics of alliances with spatial considerations that include members' contiguity, between-member distance, and contiguous threats. Given two-way causal concerns, we employ an appropriate defense demand estimator (i.e., two-step generalized method of moments) correcting for the endogeneity between a member's defense spending and that of the other allies. Evidence of defense free riding or relying on the defense spending of other AU members characterizes contiguous and nearby AU countries during 2002–2019. Defense spending is an income normal good, which generally increases with armed conflict. UN and non-UN peacekeeping troop contributions provide some free-riding opportunities within the AU. Given regional differences in armed conflicts and coups, the determinants of African defense demand are influenced by regional divisions.  相似文献

Urban political ecology (UPE) has provided critical insights into the sociomaterial construction of urban environments, their unequal distribution of resources, and contestation over power and resources. Most of this work is rooted in Marxist urban geographical theory, which provides a useful but limited analysis. Such works typically begin with a historical‐materialist theory of power, then examine particular artifacts and infrastructure to provide a critique of society. We argue that there are multiple ways of expanding this framing, including through political ecology or wider currents of Marxism. Here, we demonstrate one possibility: starting from theory and empirics in the South, specifically, African urbanism. We show how African urbanism can inform UPE and the associated research methods, theory and practice to create a more situated UPE. We begin suggesting what a situated UPE might entail: starting with everyday practices, examining diffuse forms of power, and opening the scope for radical incrementalism. © 2013 The Author.

From independence onwards, Kwame Nkrumah of Ghana pursued a position of positive neutrality and non-alignment. Historians claim that the Congo crisis and the Sharpeville massacre of 1960 led Nkrumah to question the viability of strict non-alignment. Newly declassified Ghanaian sources and an analysis of the components that make up the pan-African ideology, however, suggest that these events validated Nkrumah's pan-African worldview. Only a combination of continental unification and non-alignment was considered to be an effective strategy to avoid a repetition of the Congo debacle. Ghana's public diplomacy tactics switched from targeting political activists to convincing people through a vociferously anti-colonial propaganda campaign, a modification that cast doubt on the sincerity of Ghanaian neutrality at a moment when non-alignment actually began to affect Ghanaian diplomacy on all levels.  相似文献

This article presents the local gender contract of a smallholder irrigation farming community in Sibou, Kenya. Women's role in subsistence farming in Africa has mostly been analyzed through the lens of gender division of labor. In addition to this, we used the concept of ‘local gender contract’ to analyze cultural and material preconditions shaping gender-specific tasks in agricultural production, and consequently, men's and women's different strategies for adapting to climate variability. We show that the introduction of cash crops, as a trigger for negotiating women's and men's roles in the agricultural production, results in a process of gender contract renegotiation, and that families engaged in cash cropping are in the process of shifting from a ‘local resource contract’ to a ‘household income contract.’ Based on our analysis, we argue that a transformation of the local gender contract will have a direct impact on the community's adaptive capacity climate variability. It is, therefore, important to take the negotiation of local gender contracts into account in assessments of farming communities' adaptive capacity.  相似文献

The integration of immigrants into local labour markets is a key focus of contemporary migration scholarship in Aotearoa New Zealand. While acknowledging the importance of these economic aspects of migrant settlement, in this article we examine instead how new arrivals from South Africa actively reconstitute a feeling of home and belonging post-migration. Drawing on the concept of affect, we illustrate the ways in which the experience of migration and settlement is embodied, situated and relational. We do this by examining the affective dimensions of home-making, both within and beyond the physical boundaries of a chosen dwelling and its location. Memory bridges all these experiences of transition, suffusing migrants' lives as they understand, frame and negotiate their affective present within the context of their affective past. Our focus renders visible important aspects of the migrant experience, and contributes to a more holistic understanding of why migrants come, how they settle and what encourages them to remain.  相似文献

The culture area of Southeast United States saw the rise of the most complex societies in Native America north of Mexico before European contact. Many of these societies developed with matrilineal kinship systems. Some built impressive mounds. The “Southeast” volume of the Handbook of North American Indians presents numerous chapters that reconstruct the prehistory, history, and cultures found in this region and chronicle the European exploration and colonization that impacted the region's cultures. The differences between the prehistoric and postcolonial cultures are so great that they appear as different cultural traditions.  相似文献

Although the critical turn in place name study recognizes the central and contested place that toponyms hold in people's lives and identity struggles, little work has explicitly analyzed place naming rights in terms of social justice, citizenship, and belonging. We introduce readers to the naming of streets for slain civil rights leader Martin Luther King Jr and use two brief case studies from the southeastern USA (Statesboro, Georgia and Greenville, North Carolina) to discuss the barriers that hinder the creation of a landscape that truly reflects the teachings of King. Naming opponents, sometimes with the (un)witting cooperation of black activists, impose spatial, scalar limits on the rights of African Americans to participate in the street naming process and to appropriate the identity of streets outside of their neighborhoods, even though challenging historically entrenched patterns of racial segregation and marginalization is exactly the purpose of many street naming campaigns. The case of King streets prompts us to think about place naming as a mechanism of spatial (in)justice, demonstrating the fundamental role that geography plays in constituting and structuring the processes of discrimination or equality.  相似文献

It is hard to deny the central importance of the Freedmen's Bureau to the politics of Reconstruction. Since the 1970s, however, there has been a huge upsurge of interest in the Freedmen's Bureau. This article offers some reflections on the state of the scholarship today, and suggests that what the ‘New Freedmen's Bureau Historiography’ has taught us is that, within the parameters set by the unforgiving dynamics of Reconstruction, Bureau agents, most of them at least, struggled to negotiate the terms of freedom for African Americans. By probing the variations, the tensions, the contradictions in the agency's history, ‘New Freedmen's Bureau Historiography’ has left us with a more complete and detailed picture of the practical workings of Reconstruction on the troubled ground of the postbellum South.  相似文献
