Jean Comandon Neuroscientist

The microbiologist Jean Comandon is famous for his studies on the movement of the syphilis bacteria as differentiated in various forms by ultramicroscope. He was also a pioneer on the technical application of the microcinematography in laboratory research. His collaboration with clinicians and surgeons in the study of various pathological disorders is little known. From 1918 to the 1920s, he collaborated with such neurologists as André Thomas, Jean Athanase Sicard, and others in the study of various neurological disorders by using cinematography as a scientific tool for understanding the clinical and pathological mechanisms of diseases. These collaborations allowed him to be involved in the beginnings of the French cinematography industry, especially with Charles Pathé who established a small film studio laboratory in Vincennes where a multidisciplinary group improved the application of cinematography in clinical medical practice.     

New applications of LA–ICP–MS for sourcing archaeological ceramics: microanalysis of inclusions as fingerprints of their origin

This paper presents the latest methodological advances using the LA‐ICP–MS technique for differentiating the origin of petrographically and chemically similar ceramic raw materials. Based on several examples form the Armorican Massif (France), from a chronological period extending from the Neolithic to the Second Iron Age, we will show that the comparison of the chemical signatures of minerals included in fired clay with those from clay and source rocks enables us to distinguish productions and to accurately trace the sources of the raw materials used by potters.     

Power Relations and Upgrading in the Cashew Value Chain of Côte d'Ivoire

Development organizations are increasingly adopting market‐based approaches to reducing rural poverty and food insecurity in the global South. The value chain approach is particularly popular. Aid donors, governments and non‐governmental organizations are applying value chain concepts originally designed for promoting industrial production to smallholder agricultural production. Cashew development in Côte d'Ivoire illustrates this new approach to rural development in which ‘upgrading’ the production and processing links are top priorities. A core assumption informing this approach is that improvements in product quality at the producer level will yield higher producer prices and incomes. This article examines this assumed quality–price relationship through a comparative analysis of cashew quality and prices in Côte d'Ivoire. The research reveals a disconnect between nut quality and producer prices. The case study demonstrates that power relations are more important than quality in setting producer prices for raw cashew nuts.     

Informal housing,spatial structure,and city compactness

This paper develops a monocentric city model with a formal and an informal sector in the housing industry. While formal developers build houses renting land from landowners, informal developers use land for free. However, informal developers must incur defensive expenditures to avoid government intervention. In equilibrium, at any distance of the central business district (CBD), informal developers use land until the value of the marginal productivity of land equals the defensive expenditures per unit of land. The model shows the land allocated to produce short informal (tall formal) buildings increases (decreases) with distance to the CBD. Thus, the model introduces a new source of spatial variation of building height. The model also shows that a higher level of informal housing increases the spatial size of a city and reduces the height of its buildings.     

More than trees: The challenges of creating a geodatabase to capture the complexity of forest history

European forests have been copiously documented for centuries. However, forest-related archival sources were rarely utilised to their full potential, mainly because of the difficulties in producing compatible data from large amounts of very different sources. Furthermore, analysing such data for larger areas in high resolution was hardly possible prior to the emergence of historical GIS. This paper presents the geodatabase of the LONGWOOD project, which includes tens of thousands of pieces of information on forest history from the 11^th to the 20^th century for 3,567 townships in the eastern Czech Republic (c. 27,000 km²). The paper describes the challenges we met, briefly summarizes the results, evaluates the database in a worldwide context and introduces possible directions for future research.     

Digital Technology and a Community Framework for Heritage Rock Art Tourism,Makgabeng Plateau,South Africa

Using digital technologies in the process of collecting and documenting oral heritage allows previously marginalised voices to feed into heritage and historical narratives for rock art heritage tourism. Literary heritage narratives have tended to dominate the dissemination of information on African heritage, whereas African cosmologies and oral traditions are the intangible values of place that attract visitors to heritage sites. In the Makgabeng, oral heritage narrated through stories, songs, dances and poetry and collected using digital technologies will help preserve African values threatened by the onslaught of Western ones, especially through written European languages and social media. The Makgabeng Community Rock Art Project re-values the role of elders in sustainability of heritage tourism initiatives and the integration of a community structure as a sustainable “ready-made” framework to heritage management in Africa.     

Collections,Collecting and Collectives: Gathering Heritage Data with Communities in the Mountains of Matatiele and Lesotho,Southern Africa

Gathering digital data is a twenty-first-century research concern. Working in the previously undocumented region of the Eastern Cape’s former 'Transkei' homeland presents several data collection opportunities and obstacles. Local community collectives can vastly enhance the data collection process, aiding in administration, field walking, translation and—as trained archaeologists—excavation and rock art documentation. In the last 7 years, the Matatiele Archaeology Rock Art (MARA) team has discovered over 240 archaeological sites, the vast majority of which contain rock art. The principal investigator (PI), postdoctoral fellows, technical skills specialists and students have all engaged with, helped train and benefitted from field technicians chosen by the local communities to work with us. With their help, we have undertaken excavations and taken thousands of documentary photographs. We have documented oral traditions and the indigenous knowledge of local healers, all of which research is produced, and stored, digitally and requires preservation in perpetuity. The present contribution outlines some of the many and varied ways in which this programme has undertaken these tasks, in the endeavour to redress the imbalance in this region’s history.     

Settlement and Trade from AD 500 to 1800 at Angoche,Mozambique

Angoche was an important historic trading port on the northern Mozambique coast. A maritime archaeological survey was undertaken of the islands and mainland to study Swahili trade, clarify the sequence of settlement development and record the exploitation of resources during the medieval and post-medieval periods. Previous archaeological investigations have revealed local ceramics from the early second millennium AD and imports from the late fifteenth century. According to oral traditions and ancient sources, Angoche’s growth is associated with the arrival of coastal settlers from Kilwa in 1485. The survey revealed evidence for occupation dating from c. AD 500 and trading evidence from the late first millennium AD. Artefacts from the thirteenth to sixteenth century on the islands are similar to those found at Kilwa and Sofala, which shows a link to Kilwa earlier than the oral traditions and the name of one of the Angoche Islands ‘Quilua’, is Kilwa in Portuguese. The islands are well resourced in terms of rice, mangrove wood, seafood and farmland and offer sheltered inlets and access to the coastal trade route. The name of Angoche relates to a port of call and the presence of ninth-tenth-century- storage vessels from southern Iran supports this theory. Traded glass and ceramic artifacts and beads increase from the late medieval period revealing that Angoche became an important and wealthy entrepôt. The lack of coral limestone and reef coral, on the sandy Angoche Islands, indicates some building materials would have had to have been imported. Although many buildings would have been made of wood, some stone ruins are likely to have been demolished and burnt to make lime. The original stratigraphy of many sites has been destroyed by aeolian and marine processes but the survey has shown that valuable information on settlement location and ethnographic practices can still be recovered.
