The sky is the limit: reconstructing physical geography from an aerial perspective

In an era of rapid geographical data acquisition, interpretations of remote sensing products are an integral part of many undergraduate geography degree schemes but there are fewer opportunities for collection and processing of primary remote sensing data. Unmanned Aerial Vehicles (UAVs) provide a relatively inexpensive opportunity to introduce the principles and practice of airborne remote sensing into field courses, enabling students to learn about image acquisition, data processing and interpretation of derived products. Two case studies illustrate how a low-cost “DJI Phantom Vision+” UAV can be used by students to acquire images that can be processed using Structure-from-Motion photogrammetry software. Results from a student questionnaire and analysis of assessed student reports showed that using UAVs enhanced student engagement and equipped them with data processing skills. The derivation of bespoke orthophotos and Digital Elevation Models has the potential to provide students with opportunities to gain insight into various remote sensing data quality issues, although additional training is required to maximize this potential. Recognition of the successes and limitations of this teaching intervention provides scope for improving future UAV exercises. UAVs are enabling both a reconstruction of how we measure the Earth’s surface and a reconstruction of how students do fieldwork.     

At Intersections of Technology and a Modern Mass Medium

This article examines the intersections of technology and the exhibition medium by focusing on an individual, the mechanical engineer Robert Runeberg. It makes visible individual involvement in transnational mobility and in large-scale processes of modernization. The article explores how becoming a modern professional was not only connected to formal education and practical training, but also to the capacity to extract and produce knowledge via the exhibition medium. Concurrently, the case discloses essential qualities, such as the cohesion, dynamicity and flexibility of the exhibition medium.     

In defence of the Indo-Pacific: Australia's new strategic map

The 2013 Australian Defence White Paper categorically termed Australia's zone of strategic interest the Indo-Pacific, the first time any government has defined its region this way. This raises questions about what the Indo-Pacific means, whether it is a coherent strategic system, the provenance of the concept and its implications for Asian security as well as Australian policy. Indo-Pacific Asia can best be understood as an expansive definition of a maritime super-region centred on South-East Asia, arising principally from the emergence of China and India as outward-looking trading states and strategic actors. It is a strategic system insofar as it involves the intersecting interests of key powers such as China, India and the USA, although the Indo-Pacific subregions will retain their own dynamics too. It suits Australia's two-ocean geography and expanding links with Asia, including India. The concept is, however, not limited to an Australian perspective and increasingly reflects US, Indian, Japanese and Indonesian ways of seeing the region. It also reflects China's expanding interests in the Indian Ocean, suggesting that the Chinese debate may shift towards partial acceptance of Indo-Pacific constructs alongside Asia-Pacific and East Asian ones, despite suspicions about its association with the US rebalance to Asia. Questions about Australia's ability to implement an effective Indo-Pacific strategy must account for force posture, alliance ties and defence diplomacy, as well as constraints on force structure and spending.     

What is a Burin? Typology,Technology, and Interregional Comparison

Classification of artifacts has long marked a significant edge between theory and practice in archaeology. While considering classification to be a necessary methodological device, most practitioners also recognize that it carries with it built-in assumptions. This essay approaches the issue by way of a specific stone tool type from Old World sites: the burin. By asking “what is a burin?” the study shows the need to reconsider typologies to reflect changes in research questions and progress in dating methods, especially when working with museum collections and secondary data between regions and across national traditions, and the need to study whole collections from the perspective of technological choices.     

The Archaeology of the Gaucho <Emphasis Type="Italic">“Vago y Mal</Emphasis><Emphasis Type="Italic">Entretenido”</Emphasis>

The purpose of this article is to explain and discuss the essential operational characteristics of the technology of power (sensu Foucault) perpetrated on the internal frontiers with the Indians in nineteenth-century Argentina. The conquest and colonization of the Pampas took shape in the establishment of military camp structures placed to create a defensive cordon, known as “the Indian frontier line.” These constructions were fortlets defended by gaucho cavalry squadrons (know as Blandengues during the Spanish period, and then Guardias Nacionales after Argentinean Independence). This process is known in Argentinean historiography as “the conquest of the desert.” This particular technology of power existed in this historical context and operated at every social level, impacting strongly on the lower classes that inhabited the incorrectly named “desert.” Its implementation in the military field enabled the existence of an array of micro-powers that surrounded the gaucho, called vago y malentretenido—“a vagrant and lingerer”—and their women's lives. The army as institution was the locus of various forms of coercion and old forms of punishment (such as the stakes, whipping, and public executions) most of which affected peasants, nonresidents, itinerant workers, and the rural youth. This schema was adopted in different areas: in the enrolment and discipline of the gaucho soldiers, in life in the fortlet-prisons, and in the ritualism of power. The alternative chosen by soldiers to evade this technology of power and the fortlet-panopticons was escape through desertion. The utility of those observations is demonstrated, because an important part of the area of research of historical archaeology that has developed with the greatest impetus in Argentina has taken fortlets as its subject of study.     

Interpreting pachyderm single carcass sites in the African Lower and Early Middle Pleistocene record: A multidisciplinary approach to the site of Nadung’a 4 (Kenya)

Nadung’a 4 is one of the single carcass pachyderm sites recorded in East Africa during the Lower and Early Middle Pleistocene. The site has yielded an abundant lithic assemblage in close association with the partial carcass of an elephant. Conjoined pedological, geoarchaeological, spatial, technological, and taphonomical analyses have been carried out to address the relationship between hominids and elephant. The resulting data are consistent with a non-fortuitous association between both categories of remains. The lithic artefacts do not match a classical Acheulean tool-kit, as would be expected for the time period ascribed to the site, and the functional patterns inferred from their analysis make this site radically different from other purported butchery sites. The implications of these original features are discussed.
