Integrating radar and laser-based remote sensing techniques for monitoring structural deformation of archaeological monuments

Ground-Based Synthetic Aperture Radar Interferometry (GBInSAR) and Terrestrial Laser Scanning (TLS) were purposely integrated to obtain 3D interferometric radar point clouds to facilitate the spatial interpretation of displacements affecting archaeological monuments. The paper describes the procedure to implement this integrated approach in the real-world situations of surveillance of archaeological and built heritage. Targeted tests were carried out on the case study of the Domus Tiberiana sited along the northern side of the Palatino Hill in the central archaeological area of Rome, Italy, and displacements of the monument were monitored over almost one year of acquisition. The GBInSAR – TLS integration provided updated information about the condition of the archaeological structures in relation to their history of instability mechanisms, and did not highlighted a general worsening for the stability of the entire monument. Point-wise and prompt detection of displacement anomalies and/or sudden changes in displacement trends proved the suitability of the method to support early warning procedures, also to evaluate effects on the masonry due to human activities.     

Fluid evolution along multistage composite fault systems at the southern margin of the Lower Palaeozoic Anglo-Brabant fold belt, Belgium

Mineralised vein systems have been investigated at nine localities at the southern margin of the Anglo‐Brabant fold belt in Belgium. During the late Silurian to early Middle Devonian Caledonian orogeny, shear zones formed, inferred to be associated with granitoid basement blocks in the subsurface. The circulation of a metamorphic fluid, possibly originating in the Cambrian core of the fold belt, along these shear zones resulted in the formation of mesozonal orogenic mineralisation at the southern margin of the Anglo‐Brabant fold belt. The fluid had a composition dominated by H₂O–CO₂–X–NaCl–KCl. The shear zones form part of a greater fault zone, the Nieuwpoort–Asquempont fault zone, which is characterised by normal faulting that started before the Givetian and by the reactivation of the shear zones. Two fluid generations are associated with this normal faulting. First, a low salinity H₂O–NaCl(–KCl) fluid migrated through the Palaeozoic rocks after the Silurian. Based on the isotopic composition, this fluid could be a late‐metamorphic Caledonian fluid or a younger fluid that originated from the Rhenohercynian basin and interacted with Lower Devonian rocks along its migration path. Second, a high salinity H₂O–NaCl–CaCl₂ fluid was identified in the fault systems. Similar fluids have been found in southern and eastern Belgium, where they produced Mississippi Valley‐type Zn–Pb deposits. These fluids are interpreted as evaporative brines that infiltrated the Lower Palaeozoic basement, from where they were expelled during extensional tectonism in the Mesozoic.     

Human ecological niches and ranges during the LGM in Europe derived from an application of eco-cultural niche modeling

We apply eco-cultural niche modeling (ECNM), an heuristic approach adapted from the biodiversity sciences, to identify habitable portions of the European territory for Upper Paleolithic hunter-gatherers during the Last Glacial Maximum (LGM), circumscribe potential geographic extents of the Solutrean and Epigravettian technocomplexes, evaluate environmental and adaptive factors that influenced their distributions, and discuss this method's potential to illuminate past human–environment interaction. Our ECNM approach employed the Genetic Algorithm for Rule-Set Prediction (GARP) and used as input a combination of archaeological and geographic data, in conjunction with high-resolution paleoclimatic simulations for this time frame. The archaeological data consist of geographic coordinates of sites dated by Accelerator Mass Spectrometry to the LGM and attributed to the Solutrean and Epigravettian technocomplexes. The areas predicted by ECNM consistently outline the northern boundary of human presence at 22,000–20,000 cal BP. This boundary is mainly determined by climatic constraints and corresponds well to known southern limits of periglacial environments and permafrost conditions during the LGM. Differences between predicted ecological niches and known ranges of the Solutrean and Epigravettian technocomplexes are interpreted as Solutrean populations being adapted to colder and more humid environments and as reflecting influences of ecological risk on geographic distributions of cultures.     

‘My Journey to School …’: Foregrounding the Meaning of School Journeys and Children's Engagements and Interactions in their Everyday Localities

This paper gives prominence to children's own accounts of school journeys. The characteristics of school journeys in Fife, Scotland are outlined, and the nature of children's school journey experiences discussed. The focus is on children in the latter years of primary school, concentrating mainly on the experiences of those who walk without adult accompaniment on their school journeys. By drawing attention to the meaning of these journeys to children this paper brings to the fore children's active and imaginative engagements in and with their environments. This situates school journeys as an integral part of children's geographies indicative of the regulation of the child's realm and the active part which children play in redefining this.     

Detection of archaeological crop marks by using satellite QuickBird multispectral imagery

The capability of satellite QuickBird imagery for the identification of archaeological crop marks is herein presented and discussed for two test sites located in the South of Italy. The selected sites, dating back to Middle Ages, were buried under surfaces covered by herbaceous plants characterized by a different phenological status (dry/green) when the satellite data were acquired.     

Developing trainee teacher practice with geographical information systems (GIS)

There is general agreement that geographical information systems (GIS) have a place within the geography classroom; they offer the potential to support geographical learning, exploring real-world problems through student-centred learning, and developing spatial thinking. Despite this, teachers often avoid engaging with GIS and research suggests that the lack of GIS training in initial teacher education is partially to blame. In response to this, this article explores how 16 trainee geography teachers were supported to develop their use of GIS across a one-year, postgraduate teacher training course in England. The project, an interpretive case study underpinned by a constructivist epistemology, used questionnaires and interviews to elicit trainees’ understandings of the nature of GIS, and to explore their engagement with it across their training year. Results suggest a programme of embedded training developed in trainees a more nuanced understanding of the value of GIS for supporting geographical learning and, thereby, increased self-efficacy towards and engagement with it in their teaching practice. However, not all trainees embraced GIS as a pedagogical tool and the study raised several key issues for geography teacher education, including the knowledge culture within schools in the teacher training partnership, and the importance of trainee self-efficacy towards GIS.     

Enrolling the Private Sector in Community Development: Magic Bullet or Sleight of Hand?

The role of the private sector in international development is growing, supported by new and evolving official programmes, financing, partnerships and narratives. This article examines the place of the private sector in ‘community development’ in the global South. It situates corporate community development (CCD) conceptually in long‐standing debates within critical development studies to consider the distinct roles that corporations are playing and how they are responding to the challenges and contradictions entailed within ‘community development’. Drawing on field‐based research across three different contexts and sectors for CCD in Fiji, Papua New Guinea and South Africa, the article suggests that caution is required in assuming that corporations can succeed where governments, non‐governmental organizations (NGOs) and international development organizations have so often met with complex challenges and intractable difficulties. We argue that four specific problems confront CCD: (a) the problematic ways in which ‘communities’ are defined, delineated and constructed; (b) the disconnected nature of many CCD initiatives, and lack of alignment and integration with local and national development planning policies and processes; (c) top‐down governance, and the absence or erosion of participatory processes and empowerment objectives; (d) the tendency towards highly conservative development visions.     

'Real Services': A Re-appraisal

This paper deals with 'real services' to manufacturing companies, nowadays an integral part of the toolbox of industrial policies in all advanced countries, both at regional level and within major nationwide programmes. Policy relevance is indeed the main criterion to identify concretely those services, based on their capacity to trigger learning processes and to have positive 'externalities of consumption'. The paper discusses the main problems concerning the management and evaluation of real services and outlines the key issues for the policy agenda (selection, coordination and networking; the transfer of success models; the practice of subsidiarity between different levels of government). The paper concludes by arguing the undiminished relevance of real services for contemporary industrial policies, notwithstanding the growing awareness of their limited impact.
