The Camino de Santiago comprises a lattice of European pilgrimage itineraries that converge at Santiago de Compostela in northwest Spain. This article introduces the historical and contemporary representation of these routes as a heritage complex that is imagined and codified within varied cultural meanings of a journey undertaken. Particular attention is given to the Camino Frances and the Via de la Plata, which contrast as mature and formative pilgrimage settings. Within this spatial sphere, the analysis deals with the Camino de Santiago as official heritage, as development instrument, as civil society, and as personal experience. The article concludes by offering a contemporary conceptualization of the evolving Camino de Santiago cultural heritage complex.

Observations from the HERschel Inventory of the Agents of Galaxy Evolution (HERITAGE ) have been used to identify dusty populations of sources in the Large and Small Magellanic Clouds (LMC and SMC). We conducted the study using the HERITAGE catalogs of point sources available from the Herschel Science Center from both the Photodetector Array Camera and Spectrometer (PACS; 100 and 160 μm) and Spectral and Photometric Imaging Receiver (SPIRE; 250, 350, and 500 μm) cameras. These catalogs are matched to each other to create a Herschel band-merged catalog and then further matched to archival Spitzer IRAC and MIPS catalogs from the Spitzer Surveying the Agents of Galaxy Evolution (SAGE) and SAGE-SMC surveys to create single mid- to far-infrared (far-IR) point source catalogs that span the wavelength range from 3.6 to 500 μm. There are 35,322 unique sources in the LMC and 7503 in the SMC. To be bright in the FIR, a source must be very dusty, and so the sources in the HERITAGE catalogs represent the dustiest populations of sources. The brightest HERITAGE sources are dominated by young stellar objects (YSOs), and the dimmest by background galaxies. We identify the sources most likely to be background galaxies by first considering their morphology (distant galaxies are point-like at the resolution of Herschel) and then comparing the flux distribution to that of the Herschel Astrophysical Terahertz Large Area Survey (ATLAS ) survey of galaxies. We find a total of 9745 background galaxy candidates in the LMC HERITAGE images and 5111 in the SMC images, in agreement with the number predicted by extrapolating from the ATLAS flux distribution. The majority of the Magellanic Cloud-residing sources are either very young, embedded forming stars or dusty clumps of the interstellar medium. Using the presence of 24 μm emission as a tracer of star formation, we identify 3518 YSO candidates in the LMC and 663 in the SMC. There are far fewer far-IR bright YSOs in the SMC than the LMC due to both the SMC's smaller size and its lower dust content. The YSO candidate lists may be contaminated at low flux levels by background galaxies, and so we differentiate between sources with a high ("probable") and moderate ("possible ") likelihood of being a YSO. There are 2493/425 probable YSO candidates in the LMC/SMC. Approximately 73% of the Herschel YSO candidates are newly identified in the LMC, and 35% in the SMC. We further identify a small population of dusty objects in the late stages of stellar evolution including extreme and post-asymptotic giant branch, planetary nebulae, and supernova remnants. These populations are identified by matching the HERITAGE catalogs to lists of previously identified objects in the literature. Approximately half of the LMC sources and one quarter of the SMC sources are too faint to obtain accurate ample FIR photometry and are unclassified.

Existing chemical treatments to prevent biological damage to monuments often involve considerable amounts of potentially dangerous and even poisonous biocides. The scientific approach described in this paper aims at a drastic reduction in the concentration of biocide applications by a polyphasic approach of biocides combined with cell permeabilisers, polysaccharide and pigment inhibitors and a photodynamic treatment. A variety of potential agents were screened to determine the most effective combination. Promising compounds were tested under laboratory conditions with cultures of rock deteriorating bacteria, algae, cyanobacteria and fungi. A subsequent field trial involved two sandstone types with natural biofilms. These were treated with multiple combinations of chemicals and exposed to three different climatic conditions. Although treatments proved successful in the laboratory, field trials were inconclusive and further testing will be required to determine the most effective treatment regime. While the most effective combination of chemicals and their application methodology is still being optimised, results to date indicate that this is a promising and effective treatment for the control of a wide variety of potentially damaging organisms colonising stone substrates

Rapid in situ diagnosis of damage is a key issue in the preservation of stone-built cultural heritage. This is evident in the increasing number of congresses, workshops and publications dealing with this issue. With this increased activity has come, however, the realisation that for many culturally significant artefacts it is not possible either to remove samples for analysis or to affix surface markers for measurement. It is for this reason that there has been a growth of interest in non-destructive and minimally invasive techniques for characterising internal and external stone condition. With this interest has come the realisation that no single technique can adequately encompass the wide variety of parameters to be assessed or provide the range of information required to identify appropriate conservation. In this paper we describe a strategy to address these problems through the development of an integrated `tool kit' of measurement and analytical techniques aimed specifically at linking object-specific research to appropriate intervention. The strategy is based initially upon the acquisition of accurate three-dimensional models of stone-built heritage at different scales using a combination of millimetre accurate LiDAR and sub-millimetre accurate Object Scanning that can be exported into a GIS or directly into CAD. These are currently used to overlay information on stone characteristics obtained through a combination of Ground Penetrating Radar, Surface Permeametry, Colorimetry and X-ray Fluorescence, but the possibility exists for adding to this array of techniques as appropriate. In addition to the integrated three-dimensional data array provided by superimposition upon Digital Terrain Models, there is the capability of accurate re-measurement to show patterns of surface loss and changes in material condition over time. Thus it is possible to both record and base-line condition and to identify areas that require either preventive maintenance or more significant pre-emptive intervention. In pursuit of these goals the authors are developing, through a UK Government supported collaboration between University Researchers and Conservation Architects, commercially viable protocols for damage diagnosis, condition monitoring and eventually mechanisms for prioritizing repairs to stone-built heritage. The understanding is, however, that such strategies are not age-constrained and can ultimately be applied to structures of any age.

This paper presents findings based on a palynological investigation of artificially accreting (plaggen) soils from the settlement of Village Bay, Hirta, in the St Kilda archipelago, which was perhaps the most distant and inhospitable outpost of sustained human habitation in the British Isles. The soils were developed principally through the addition of turf ash and seabird waste, although some ash may have been derived from upland peats. It is assumed that the woodland pollen signal (much lower in the soils than in an upland peat site nearby) represents off-island sources. Corylus avellana-type pollen (frequent in upland sites), along with Potentilla-type, may provide markers in the Village Bay profiles for the addition of ashed hillside turf, and possibly peat, to the plaggen soils. Cereal-type pollen is well represented through the profiles and is often strongly associated with the record for Chrysanthemum segetum (corn marigold), a frequent indicator of arable land. The Brassicaceae signal may partly reflect the cultivation of cabbages; Chelidonium majus (greater celandine) may have been grown for medicinal use. Soil mixing has rendered radiocarbon dating meaningless at this site, but the establishment of a change in cultivation regime before AD 1830 may have been identified from the patterns of pollen concentration and preservation in the profiles. © 2008 Elsevier B.V.

The garment we now recognise as the Aran jumper emerged as an international symbol of Ireland from the twin twentieth century transatlantic flows of migration and tourism. Its power as a heritage object derives from: 1) the myth commonly associated with the object, in which the corpse of a drowned fisherman is identified and claimed by his family due to the stitch patterns of his jumper (Pádraig Ó Síochain 1962; Annette Lynch and Mitchell Strauss 2014); 2) the meanings attached to those stitch patterns, which have been read, for example, as genealogical records, representations of the natural landscape and references to Christian and pre-Christian ‘Celtic’ religion (Heinz Kiewe 1967; Catherine Nash 1996); and 3) booming popular interest in textile heritage on both sides of the Atlantic, fed by the reframing of domestic crafts such as knitting as privileged leisure pursuits (Rachel Maines 2009; Jo Turney 2009). The myth of the drowned fisherman plays into transatlantic migration narratives of loss and reclamation, promising a shared heritage that needs only to be decoded. The idea of the garment’s surface acting as text (or map) situates it within a preliterate idyll of romantic primitivism, while obscuring the circumstances of its manufacture. The contemporary resurgence in home textile production as recreation, mediated through transnational online networks, creates new markets for heritage textile products while attracting critical attention to the processes through which such objects, and mythologies, are produced. The Aran jumper’s associations with kinship, domesticity and national character make it a powerful tool in the promotion of ancestral (or genealogical) tourism, through marketing efforts such as The Gathering 2013. Nash’s (2010; 2014) work demonstrates the potential for such touristic encounters to disrupt and enrich public conceptions of heritage, belonging and relatedness. While the Aran jumper has been used to commodify a simplistic sense of mutuality between Ireland and north America, it carries complex transatlantic messages in both directions.

A significant portion of UK’s infrastructures earthworks was built more than 100 years ago, without modern construction standards: poor maintenance and the change of precipitations pattern experienced in the past decades are currently compromising their stability, leading to an increasing number of failures. To address the need for a reliable and time-efficient monitoring of earthworks at risk of failure we propose here the use of two established seismic techniques for the characterization of the near surface, MASW and P-wave refraction. We have regularly collected MASW and P-wave refraction data, from March 2014 to February 2015, along 4 reduced-scale seismic lines located on the flanks of a heritage railway embankment located in Broadway, SW of England. We have observed a definite temporal variability in terms of phase velocities of SW dispersion curves and of P-wave travel times. The accurate choice of ad-hoc inversion strategies has allowed to reconstruct reliable VP and VS models through which it is potentially possible to track the temporal variations of geo-mechanical properties of the embankment slopes. The variability over time of seismic data and seismic velocities seems to correlate well with rainfall data recorded in the days immediately preceding the date of acquisition.

O presente trabalho propõe-se reflectir sobre o efeito transgeracional do Holocausto, responsável pela formação de traumas e sentimentos de culpa, como se testemunham tanto em estudos psicológicos como em textos literários. Trata-se de um factor nuclear da problemática identitária verificada junto da geração de indivíduos, nascidos após o final da ditadura nacionalsocialista. Embora esta geração não tenha vivido durante os anos da ditadura hitleriana, recai sobre ela uma herança histórica que, inevitavelmente, deixa marcas profundas no processo de construção e consolidação da identidade de cada um: se os filhos dos sobreviventes se debatem com o sentimento de "culpa pela sobrevivência" sentido pelos pais, aos filhos dos criminosos é imputada uma culpa moral pela barbárie perpetrada pelos progenitores. Esta reflexão assenta no estudo da obra dos escritores Jan Koneffke e Doron Rabinovici, jovens autores de expressão alemã, que representam os conceitos de trauma, identidade e memória no contexto histórico, político e social da actualidade.
