Analysis of the spatial distribution of geochemical signatures for the identification of prehistoric settlement patterns in ADE and TMA sites in the lower Amazon Basin

The Archeological Dark Earth (ADE) and Terra Mulata (TMA) anthrosols found at Juruti, on the lower Amazon River, extend over a wide area located within the local ferralsol domain. The ADE soils are dark in color and contain large quantities of fragmented ceramics, while the TMA soils are also relatively dark, but lack ceramics. Multi-element chemical analyses of soil samples of ADE and TMA from the A2 horizon (depths of 10–20 cm) indicated that the ADE soils are characterized by higher concentrations of P₂O₅, CaO, K₂O, MgO, Cu, Mn, and Zn, while the TMAs have median levels of these compounds, and the ferralsols have much lower concentrations. These chemical elements make up the geochemical signature of these anthrosols, whereas Al₂O₃, Fe₂O₃, TiO₂, Cr, Sr, La, Li, Ni, Pb, V, Y, and Zr characterize the geochemical signature of the ferralsols, which was identified partially in the ADEs and TMAs. The isoline maps of these two geochemical associations permitted the delimitation of the different areas and the identification of the ADEs as sites of long-term human occupancy, and the TMA as an area of temporary occupation associated with agricultural activities. Seven villages were delimited within the study area, and were separated by corridors of ferralsols. These settlements were established on the riverbank, with the more temporary cultivated areas behind them, running almost parallel to the river. The identification of functional patterns based on geochemical associations, the abundance of ceramic material, and concentrations of organic matter, indicated that an area of more than 350 ha was occupied.     

The transatlantic Muslim diaspora to Latin America in the nineteenth century

Since the 16th century, African Muslims figured prominently among the slave population of the Americas. While the number of Muslims pulled into the trade has always been a matter of speculation, lists of Africans rescued from slave ships provide us with some clues about the size and direction of the Muslim diaspora to Latin America in the 19th century. Based on an analysis of tens of thousands of names recorded in these lists, this essay argues that the majority of Muslim captives leaving Africa departed from Upper Guinea and suggests that Cuba was the center of the forced Muslim diaspora in the Americas. It traces the transatlantic links that connected particular regions of embarkation in Africa to their counterparts in Latin America and considers the implications of those connections for religious and cultural change within 19th-century slave populations. The essay challenges in important ways the colonial/postcolonial divide in Latin American history and uses Islam to pose important questions about the dynamics of social change across slave societies.

Wine tourism development in South Africa: a geographical analysis

ABSTRACT

Wine tourism, which is growing and developing on a global scale, is widely considered a driver of economic and social development in rural areas. Limited job opportunities and unemployment are prevalent in most rural areas, particularly in South Africa. In 2015, the South African wine industry generated close to 300,000 direct and indirect employment opportunities. A geographical analysis of the development and current state of wine tourism in the region can assist in the country's efforts to develop a new strategy to enhance and preserve wine tourism in the future. Wine tourism development is analysed from a nodes, network and winescape perspective using the results from a national questionnaire survey. This mostly quantitative approach explains the wine tourism development over more than 40 years from a supply-side perspective including its wine tourism product portfolio and in terms of its physical footprint. Wine tourism development commenced from only three pioneer open cellar doors in 1971, to network formation of 21 wine routes and today boasting well-established wine tourism destinations. The Stellenbosch-Franschhoek-Paarl nexus emerges as South Africa's premier winescape, as being a well-established destination in its mature life cycle phase. Strong evidence of hierarchical differentiation between the wineries of the more established wine tourism regions has emerged. The impact of the wine tourism resorts on the smaller wineries has yet to be determined in the context of the resilience of the whole region. The development of wine tourism is also responsible for the transformation of rural landscapes and especially in the regions that have the most developed wine routes. These regions need higher-level protection (especially the cultural and natural resource bases) in the form of an ‘agricultural reserve’ or the declaration of a ‘national heritage site’.     

Dental Modifications in a Skeletal Sample of Enslaved Africans Found at Lagos (Portugal)

An archaeological intervention in Valle da Gafaria (Lagos, Portugal) allowed the excavation of a deposit of waste dating from the 15^th to 17^th centuries. Among discarded objects, an important amount of human skeletal remains was exhumed (N = 158 individuals). The archaeological and historical context, as well as the morphometric analysis of the skulls, led us to attribute them an African origin. While historical sources document the trade of slaves by the Portuguese since the 15^th century, so far no slave cemetery was excavated in Portugal. The study of their lives and deaths has been accomplished by historical documents. Therefore, this sample provides a unique opportunity to learn more about captive individuals who were brought to Portugal in the modern period. The present work focuses in the intentional dental modifications presented by several of these individuals. A total of 113 subjects have teeth that can be evaluated for the presence of intentional modifications. Of these, 55.8% individuals present dental modifications on their anterior dentition, 42.9% exhibiting modifications on both upper and lower teeth. The incisors were the most frequently modified teeth, followed by the canines. Both men and women as adults and sub‐adults have dental intentional modifications. In most individuals, dental modifications involved the removal of the mesial and distal angles, which is comparable with sub‐Saharan African practices. However, we cannot infer a more specific origin for these slaves only based on dental modification's type and pattern because several ethnic groups modify teeth in the same way.

Investigation of chemical changes in bone material from South African fossil hominid deposits

The bone fragments of the Australopithecus Africanus from the dolomitic cave in the Cradle of Humankind in South Africa have been studied by the use of several spectral techniques. The aim was to establish their degree of preservation and possibilities of inferring the life conditions from them. X-ray diffraction studies revealed the transformation of the mineral components partially into fluoroapatite form with addition of goethite, birnessite and quartz phases and with surprisingly well preserved collagen remains. Several important chemical elements were detected by using the electron (EPMA) and synchrotron-based X-ray fluorescence (XRF) microprobes. Among them, Sr and Zn were distributed in a way following the distribution of Ca, the main element of the bones. We suspect the immanent crystallographic substitution of Ca in this case in native bone. Iron followed the distribution of Sr but while Sr is distributed in a continuous way in more rigid locations, iron occurs mainly in the edge zones of the bones and in spot-like inclusions inside. Some part of the spots located in a very edge of bone is also filled with Mn and Cu. It suggests that the porosity and fracture of bones plays a more significant role in the localization of Fe, Mn and Cu. They also form a rigid thin layer (100–250 μm) avoiding further penetration. As (as AsO₄³⁻?) distribution pattern is unique and seems to occur in those locations where the concentrations of Sr are small. The conditions for bone penetration as determined from Eh-pH diagrams suggest that is rather impossible to preserve the organic matter in locations of Mn and also that Mn and Fe hardly can meet in the same spots.     

The Poor Law of old England: institutional innovation and demographic regimes

The striking improvement in life expectancy that took place in England between the Middle Ages and the seventeenth century cannot be explained either by an increase in real wages or by better climatic conditions. The decrease in the risk of utter destitution or of death from famine that was evident on the eve of the Industrial Revolution stemmed, in part, from institutional changes in the old poor law, which began to take shape and become effective early in the seventeenth century.     

论中世纪晚期英国议会政治

在学术界,似乎有一个不证自明的定论,即：作为近代资本主义政治制度核心构件的议会政治是与中世纪封建社会无缘的。但事实上,在特定历史条件下,两也完全有可能联系在一起。英国由于在早期历史中形成了政治协商传统和初步成型的议会协商机制以及相应的社会化理念,从而为中世纪晚期出现议会政治奠定了必要的历史基础;但历史基础仅仅提供了议会政治早产的可能性,而将这种可能变为现实的决定性力量则是当时各种具体的特殊原因和个人因素构成的偶然机缘。换言之,中世纪晚期英国议会政治的早产是一种历史偶然现象。由此可见,偶然因素也是一种应当给予充分重视的历史决定性力量。     

Best practices for measuring community resources across Canada: A comparison of coding classifications

Social scientists, geographers, criminologists, and health scientists are often tasked with finding data to best capture the impact of “community context” on individual outcomes, including residential services, physical resources, and social institutions. One outlet for such data in Canada is Digital Map Technologies Inc. (DMTI) Spatial, which offers a national repository of over one million businesses and recreational points of interest. The database is generated through CanMap Streetfiles, which includes geocodes of each point's precise location. These data are available to researchers from their university data library and Esri Canada, but primarily available to private sector and government markets. That said, the goal of the current paper is to encourage researchers to access this rich yet under-utilized data source. Each service, business, or resource in the DMTI Spatial database is assigned to a respective category using Standard Industrial Classification codes and North American Industrial Classification System codes. It is not clear, however, which is the more reliable coding criteria. We provide an overview of our review of DMTI Spatial data and take-away suggestions for using this valuable resource for future research on meso-level residential markers.
