Augmenting the landscape scene: students as participatory evaluators of mobile geospatial technologies

This paper provides a two-phase study to compare alternative techniques for augmenting landscape scenes on geography fieldtrips. The techniques were: a pre-prepared acetate overlay; a custom-designed mobile field guide; a locative media app on a smartphone; a virtual globe on a tablet PC; a head-mounted virtual reality display, and a geo-wand style mobile app. In one field exercise the first five techniques were compared through analysis of interviews and student video diaries, combined with direct observation. This identified a particular challenge of how to direct user attention correctly to relevant information in the field of view. To explore this issue in more detail, a second field exercise deployed “Zapp”, a bespoke geo-wand-style app capable of retrieving information about distant landscape features. This was evaluated using first-person video and spatial logging of in-field interactions. This paper reflects upon the relative merits of these approaches and highlights particular challenges of using technology to mimic a human field guide in pointing out specific aspects of the landscape scene. We also explore the role of students acting as design informants and research co-participants, which can be mutually beneficial in promoting a critical appreciation of the role of technology to support learning about the landscape.

‘The fieldworker not in the head's office’: an empirical exploration of the role of an English rural primary school within its village

This paper presents the findings of a project exploring the role of an English primary school inside its rural village. The fieldwork discovered that the school had lacked a full-time head teacher for a number of years and the paper explicates three dynamics to unravel why: (1) interpersonal issues (high staff turnover and the legacy of a former head); (2) the political–economic development of the village and its shifting local ‘squirearchy’; and finally (3) the construction of the spatial environment of the village (post-war expansion and the situation of amenities). These three dynamics possessed a synergy and this was key in seeing the complexities of this rural environment and its bearing upon social relations such as the absent head. It therefore supports recent theorising positioning interpersonal power alongside the temporal and spatial character of a local environment. The paper concludes by using this insight to consider what problems the school—and any new head teacher—might face in the immediate future. The research is based on ethnographic fieldwork conducted in 2009–2011.Using a multi-strategy research approach, the paper draws upon participant observation, interview, documentary, visual and historical material in support of its analysis.     

Exploring chronic arsenic poisoning in pre-Columbian Chilean mummies

This paper explores to what extent arsenic poisoning affected pre-Columbian northern Chile populations living between Arica and Iquique cities. We hypothesize, the pre-Columbian inhabitants of this region, will show arseniasis according to modern geographic endemic levels. Continuous exposure to high levels of arsenic causes serious health problems. Today, in the Camarones valley, where many Chinchorro people lived, arsenic levels are 100 times above the 10 μg/L recommended by the World Health Organization (WHO). Using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) we determined arsenic levels in a single strand of hair of 45 Arica mummies coming from ten sites (Morro 1, Morro 1/5, Yungay 372, Camarones 8, 9, 15D, and 17 and Azapa 140, Sermenia and Patillos), ranging from Chinchorro (ca. 5000–2000 years B.C.) to the Late Intermediate Period (1000–1400 years A.D.). Each hair was cleaned using distilled ionized water and placed on double sided mounting tape and ablated using a 266 nm Nd-YAG UV laser. Hair samples were also investigated for potential diagenesis.     

The application of 3D laser scanning technology to the assessment of ordinal and mechanical cortex quantification in lithic analysis

Recent studies make use of cortex proportion as a proxy measurement for the impact of artefact transport on assemblage formation. Cortex in these studies is measured on an ordinal scale and analysed in relation to mechanical measurements of artefact size. Here we report on the use of a 3D laser scanner to obtain precise measurements from experimental lithic reduction sets. High-resolution measurements of cortex area are compared to measurements obtained through ordinal approximations of cortex proportion and mechanical approximations of artefact size. While the ordinal and mechanical measurements result in considerable error for individual artefacts, estimates improve significantly as sample size increases.

The politics of protecting the poorest: Moving beyond the ‘anti-politics machine’?

Famously derided as the ultimate ‘anti-politics machine’, international development has increasingly sought to integrate a stronger political perspective within its ambit. This includes devising new forms of political analysis to inform development interventions and efforts to support forms of politics that are deemed to be ‘pro-poor’. However, this engagement with pro-poor politics remains limited and the agenda of advanced liberalism that international development agencies remain embedded within tends to draw its understandings of politics from ideology rather than evidence. Case-study analysis of the politics associated with successful social protection interventions in eight countries suggests that the political modes preferred within advanced liberalism – including civil society representation, inclusive policy spaces, and securing ownership – have been much less important in securing poverty reduction than more deeply political institutions and processes, particularly efforts from within political society to re-embed capitalism and extend social contracts to previously marginal groups. Deeper forms of political, political economy and political geography analyses are required to capture the politics of reaching the poorest groups, which needs to be understood in terms of processes of capitalist and political development that have important spatial dimensions, and which can be conceptualised in terms of extending the ‘social contract’ between states and citizens.
