Monitoring façade soiling as a maintenance strategy for the sensitive built heritage

The color patterns generally found on the façades of architecturally sensitive buildings have an adverse impact on their aesthetics, to the detriment of their identity and potential economic value. A quantitative and qualitative study was conducted of the perception of aesthetic decay in the limestone on a heritage building. The study assessed building aesthetics between two façade cleaning operations, conducted in 1984–1986 and 2006–2008. Based on the calculation of the final or total soiling index, by means of in situ lightness measurement and three architectural design variables, the color distribution of the façades was quantified in 2006 and a model was developed to monitor façade soiling over time. The proposed model, a tool for planning preventive façade maintenance on architecturally sensitive buildings, advocates for sustainable cleaning operations. Its premise that periodic cleaning should only be conducted in areas where the limestone is affected by aesthetic decay redounds to minimised intervention and lower building management costs.     

Investigation Techniques for the Seismic Response Assessment of Buildings Located in Historical Centers

ABSTRACT

It is an acknowledged fact that historical centers, given its significance from the cultural and architectural viewpoint, bring further challenges in terms of maintenance planning, survey, and safety assessment. The preparation of an adequate investigation plan and the extent of data to be collected is highly reliant on many aspects, such as the category of the architectonic asset, the importance of the heritage site, or the resources available, for example. In what regards the seismic response assessment of urban cultural heritage assets located in historical centers, the amount and detail of data also depend on this article, scale of assessment, and current state of conservation and occupation. Within this framework, this article provides an overview of the state of the art of investigation techniques currently used in survey operations, which are currently available for improving the knowledge level of urban cultural heritage assets within historical centers, as a supporting tool for the seismic response assessment of such singular assets. Finally, acknowledging the lack of accuracy when evaluating the seismic response of an asset enclosed in aggregate as an isolated structure, this article also focuses on the identification of the main particularities inherent to buildings enclosed in aggregate.     

Command Centre Bjorn: the conflict heritage of a Swedish Cold War military installation

This text presents the results of a contemporary archaeological investigation of an important Swedish Cold War installation, Command Centre Bjorn. This centre was connected to the Air Force Attack Squadron and together with the coastal artillery and the navy it constituted a crucial part of the Swedish defence efforts during the Cold War period. The text also discusses questions concerning heritage processes, and it stresses that a contemporary archaeology approach can contribute with new insights into the Cold War and its heritage in Sweden, as well as canalize and offer guidance to the huge public interest in the material remains from this period in Sweden.     

略论陆懋德的史学思想

陆懋德是20世纪前半期在史学理论方面颇有建树的著名学者。他强调治史应以"无所谓中西,取其长而求其是"为宗旨,以考古史料与文献材料并重的史料观审查、检验史料的真实性,用物质和心理的解释"二者当参用而不可偏用"的观点来解释历史变化、发展的过程。他的这种史学思想,是在继承前人成果与反思当时中国史学发展状况的过程中形成的,具有较强的理论价值和现实意义。     

白蚁对古代建筑的危害及防治方法研究现状

白蚁是一种古老的害虫,给国民经济带来巨大的损失,也严重危害原址保护的木质文物。本文综述了近年来国内外原址保护木质文物遭受白蚁侵害的情况以及灭治方法。其中,以昆虫生长调节剂(IGRs)为毒饵,采用监测-毒杀-再监测的方法杀灭白蚁低毒高效,对文物损害最小。另外,以寄生虫、细菌、病毒等生物感染白蚁,或采用植物及其提取物灭杀白蚁,是有待探索的灭蚁新途径。     

Conflicto político en el Poema de Fernán González

This article deals with the ways in which different political conflicts surrounding the emergence, independence, and consolidation of Castile as a political agent are managed and solved in the Poema de Fernán González. It shows how internal conflicts within the Castilian community are settled by favoring an authoritarian vision of leadership, discouraging consensus and shared decision making. Regarding conflicts with other political domains, the poem legitimizes Castilian independence by means of a narrative that makes natural Castilian claims on Visigothic heritage, while at the same time presenting Castile as following legal procedures and as a victim of external aggression.     

Using Sector‐Scan Sonar for the Survey and Management of Submerged Archaeological Sites

This article reports the results of using a sector‐scan sonar to record diverse submerged archaeological sites in shallow and deep water. The Kongsberg MS1000 sector‐scan sonar was developed for commercial applications, typically underwater inspections of bridges, dams, ports and harbours. The ability of the device to rapidly generate high‐quality, geometrically accurate scans of submerged features, coupled with its ease of use and deployment make it a potentially important, yet largely overlooked, tool for survey and management of underwater archaeological sites. As one of several technologies available, the paper examines its advantages and limitations, and considers, through case studies, under which conditions it is most effectively deployed.     

Soft power and dark heritage: multiple potentialities

Abstract

While positively connoted tangible cultural heritage is widely recognized as an asset to states in their exercise of soft power, the value of sites of ‘dark heritage’ in the context of soft power strategies has not yet been fully explored. This article offers a theoretical framework for the analysis of the multiple soft power potentialities inherent in the management and presentation of sites of past violence and atrocity, demonstrating how the value of these sites can be developed in terms of place branding, cultural diplomacy and state-level diplomacy. The relationship between dark heritage, soft power and the search for ‘ontological security’ is also explored, highlighting how difficult pasts can be mobilized in order to frame positive contemporary roles for states in the international system. Drawing on this theoretical framework, the article offers an analysis of the case of the So?a valley in Slovenia and the presentation of the site of the First World War battle of Kobarid in a dedicated museum. Through this case study, the article underlines the particular role of dark heritage for the national self-projection of a new and small state in the context of European integration.     

Entangled Memories: How to Study Europe’s Cultural Heritage

A fruitful direction for research on the European cultural heritage is to adopt a transnational approach. Rather than see cultural heritage as predominantly expressed in national contexts, it could be seen as primarily transnational and as plural. Such a view would also suggest a conception of national histories as themselves products of transnational encounters. In this perspective, the European dimension is not then necessarily something over and above nations, but part of their heritage. Moreover, as fundamentally transnational, the European heritage is not exclusively confined to Europe. Cultural heritage is not something that is fixed or based on an essence; it is produced and reinterpreted by social actors in different but overlapping contexts. This is also an interpretative approach that draws attention to the entangled nature of memories and especially the cultural logic by which new conceptions and narratives of heritage emerge from the encounter and entanglement of different memories. Such an approach offers new opportunities for comparative research on the European heritage as an entangled mosaic of histories and memories. This approach thus rejects not only particularistic but also universalistic ones such as alternative Eurocentric accounts.
