Chemical and Microscopic Study of Masonry Mortar in Ancient Pagodas in East China

Ancient mortars played a crucial role in the construction of historical architectures due to their physical and chemical compatibility with traditional building materials such as stones and bricks. Therefore, the analysis and optimization of the ancient mortar formula are significant in the restoration and preservation of historical sites. In this work, 20 mortar samples selected from five ancient stone pagodas in Zhejiang Province, China, were analyzed. The results showed that mud, lime-soil mortar, lime-sand mortar, and lime-gypsum mortar were used as binders in these pagodas. The Ca(OH)₂/aggregate ratio ranging from 0.3 to 2.7 was usually used to prepare lime mortar. Protein and polysaccharide were also found in some samples.     

Updating Numerical Models of Masonry Arch Bridges by Operational Modal Analysis

This article aims at presenting and discussing the strategies for updating the finite element numerical modeling of stone masonry arch bridges using operational modal analysis. The study comprehended three bridges: two old ones, the St. Lázaro and the Lagoncinha bridges, and a recently constructed bridge in Vila Fria, Portugal. Updating of the bridge models is performed by comparing the numerical and experimental modal parameters. Three-dimensional detailed numerical models are used to perform modal analysis of the bridges. Experimental modal identification of the bridges is based on the measurement of their acceleration responses during normal operation. The assigned material properties are also based on available results obtained from in situ and laboratory tests and on the results of visual inspection and historical research carried out for both old bridges.     

‘They have to abide by our laws … and stuff’: ethnonationalism masquerading as civic nationalism

The long established distinction between civic nationalism and ethnonationalism is useful heuristically to understand different dimensions of nationalism and perhaps track a movement from ethnic forms to civic allegiances, though some have challenged its empirical veracity and others question the normative implications of such a distinction. This paper demonstrates the ways in which the two are elided in everyday discourses about migrants in Australia. We argue suspicion of cultural difference, identified more than three decades ago as the new racism, has given way to talk of the need for migrants to ‘follow the law’. This serves rhetorically to reinforce the notion that migrants, often implied to overlap with the category ‘Muslims’, are insisting on breaking the law and/or changing it and are therefore culturally incompatible with a modern liberal democracy. We argue that since ethnic nationalism, like racism, is out of favour normatively, ethnic nationalist arguments are now superficially concealed beneath the acceptable language of civic nationalism. The manner in which this occurs is mapped discursively using data from a corpus of twenty seven focus groups conducted around Australia.     

CONTEXTS OF COLONIALISM

The contributions to the collection under review offer a wide range of treatments of ways in which German colonialism intersected with aspects of domestic German culture and politics, with particular attention to the larger global setting in which the German colonial empire existed between 1884 and 1918—or was remembered up to 1945. The review situates and critiques the contributions in interpretive contexts based on general suggestions by one of the editors, Geoff Eley. These include a context in which “colonialism” and “imperialism” are recognized as specific discursive constructions of the late nineteenth and early twentieth centuries, another in which the causal focus in interpreting colonial phenomena is placed on exchanges that constituted an accelerating globality with which available conceptual modes (including colonialism and imperialism) could not keep pace, a third that complicates the categorical distinctions usually made between types of imperial program, and a fourth that aims at replicating on a much broader and more flexible basis something like the concept of “social imperialism” that forty years ago dominated interpretations of German imperialism. The essay ends with a view of how such an interpretive framework might be constructed.     

Quantitative analysis of two low-cost aerial photography platforms: A case study of the site of Zagora,Andros, Greece

Aerial photography provides a valuable recording method for archaeological sites and is often underutilized. In the past, aerial photographic platforms were expensive and often required highly specialized equipment. However, with new technology a variety of different platforms are now available. This paper will analyze two low cost aerial photographic platforms used at the Australian Archaeological Institute at Athens/University of Sydney's project at Zagora, on the island of Andros, Greece. Over two years, both kites and drones were used with relative success. Through a review of the application of both systems on the project, along with a quantitative analysis of the cost, transportability, operation and quality of photographs, the strengths and weaknesses of both platforms will be discussed.     

Testing settlement models in the early Roman colonial landscapes of Venusia (291 B.C.), Cosa (273 B.C.) and Aesernia (263 B.C.)

This paper examines settlement density and settlement patterns in the Roman colonial territories of Venusia, Cosa and Aesernia, located in three different landscapes of central southern Italy (modern Basilicata, Tuscany and Molise). Using a series of GIS tools, we conducted a comparative analysis of the density and spatial distribution of sites dating to the Hellenistic period (ca. 350–50 b.c.). We used the legacy settlement data collected by previous large-scale, intensive, site-oriented field surveys to test the validity of two competing rural settlement models of early Roman colonization: the conventional model of neatly organized settlements regularly dispersed across the landscape and the recently proposed theory that colonists adopted a polynuclear settlement strategy. After calculating the extent to which the archaeological datasets conform to the regular or polynuclear model, we conclude that only a very small portion of the colonized areas actually meets traditional expectations regarding the organization of early colonial settlements. Our analyses show that the legacy survey data is more consistent with the polynuclear settlement theory, but the data also reveals some completely unexpected patterns, suggesting that early Roman colonial landscapes were more diverse than previously thought.     

Policy Networks in Complex Governance Subsystems: Observing and Comparing Hyperlink,Media, and Partnership Networks

Methods for observing policy networks have not kept up with the development of new network analytic techniques required to understand governance in complex settings. We compare three unobtrusive methods for observing policy networks based on hyperlinks between policy actor web sites, on media reports, and on public policy partnerships. Observations of one complex local water policy arena with all three methods provide a comparison of the general as well as actor‐specific network characteristics in the three observed networks. The core network of actors observed by all methods has similar network level statistics, highly correlated relationships measured by Quadratic Assignment Procedures models, and the same significant network microstructures as measured by Exponential Random Graph Models. The full networks including actors observed by any method also exhibit similar actor‐level characteristics, although the correlations across networks are stronger for bridging capital measures than for bonding capital measures, and each method has different apparent biases. Once biases are accounted for, similarities suggest that these methods may provide useful proxies for each other and for other relationships that are more difficult or impossible to measure, particularly when combined to offset each method's biases. If so, they can extend the range of policy networks observable with limited resources across space and time.     

“Broken Hearted” and “Crushed in Spirit”: Metaphors and Emotions in Psalm 34,19

In the Old Testament, the book of psalms stands out because of its vast and rich imagery and vivid metaphorical language. Deep human experiences and a wide range of human emotions in its heights and depths can be discovered there. The metaphorical language in the Old Testament, particularly in the psalms, is often linked with emotions. This paper centres on emotions within the metaphor discourse and aims to contribute to two fields of research: firstly, the field of metaphor analysis in the psalms and secondly, the area of the Studies of Emotions by using Ps 34,19 as an example. After presenting some core theoretical concepts regarding the study of metaphors and emotions, the analysis of the form and content of Ps 34 as well as the “broken hearted” and “crushed in spirit” in Ps 34,19 will be carried out. The results of the analysis shed new light on the well-known verbal images of the “broken hearted” and “crushed in spirit.”     

Defining “Official” Built Heritage Discourses within the Irish Planning Framework: Insights from Conservation Planning as Social Practice

Conservation of built heritage is a key planning process and goal which shapes urban development outcomes across European cities. In Ireland, conservation of the built heritage is a key part of the planning framework, albeit one that is, in comparative terms, only recently established. While it is widely recognized that the underlying rationale for conservation of built heritage varies considerably (from cultural priorities to place marketing), the literature suggests that heritage and conservation professionals perform a key role in controlling decision-making through an official or “authorized” heritage discourse (AHD), emphasizing expert values and knowledge and based around selective heritage storylines often reflecting elite tastes. Drawing on policy and practice in Ireland, in this paper, we contribute to these debates by further unpacking the AHD, exploring tensions within the heritage policy elite through examination of competing views and representations relating to the purpose of built heritage protection. Based on a discourse analysis following interviews with key national actors, we identify two key narratives—a “museum-curatorial” discourse and an “inclusive heritage” discourse—which in turn frame conservation practices. We argue that subtle variations of heritage meanings have the potential to either reproduce (museum-curatorial discourse) or challenge (inclusive heritage discourse) conventional modes of practice, particularly relating to the relationship between built heritage and identity and the role of public engagement.     

Borders,planning and policy transfer: historical transformation of development discourses in the Finnish Torne Valley

European Union spatial policies have become a key institutional context in which to study policy transfer processes in European border areas. These policies are, however, only the most recent part of these transformation processes which raises a need for more historically sensitive approaches. An historical perspective is important, since border regions are historical processes with particular path-dependent development trajectories and power structures. This paper aims to contribute to the discussion concerning the transformation of European border regions by looking at the policy transfer of regional development discourses in the Finnish Torne Valley. The study material consists of strategic development documents produced by the Finnish border municipalities and the municipal-based co-operation organizations from the 1930s to 2013. The examination, based on critical discourse analysis, shows that the transformation process is driven by national trends and the dominant planning discourse. Nevertheless, the particular border setting and local discourse on ‘united Torne Valley’ have also intertwined with political and economic processes during different time periods.
