Building survey forms for heterogeneous urban areas in seismically hazardous zones. Application to the historical center of Valparaíso,Chile

ABSTRACT

Building survey is an essential data-collection procedure to feed large-scale seismic vulnerability assessment. The available strategies usually consider survey forms to gather information about the urban buildings. The application of the available survey forms poses important challenges for the case of the heterogeneous urban centers including different structural typologies. This work proposes four specific survey forms for traditional structural typologies constructed with masonry, reinforced concrete, mixed steel-reinforced concrete, and timber. The proposed forms request essential information on the parameters necessary for seismic vulnerability assessment, by evaluating the lateral-load resistant system, regularity, condition of conservation, and existing damages. The survey forms were applied to the study of 111 buildings of the historical center of Valparaíso, Chile. The proposed methodology was complemented with the use of Geographic Information Systems to obtain a complete database with the structural characterization of the most representative typologies for future works of large-scale seismic vulnerability assessment.     

Explaining voting in the 2017 Australian same-sex marriage plebiscite

The 2017 Australian Marriage Law Postal Survey led to the adoption of same-sex marriage. Using ecological analysis, this paper tests five hypotheses to explain voting in the plebiscite. Social characteristics exerted a strong influence on the vote, with a higher ‘yes’ vote in more affluent and suburban electorates, and a higher ‘no’ vote in electorates with large numbers of traditional households. The strongest predictor of a ‘no’ vote was electorates with large proportions of newly arrived immigrants. Electorates that had larger proportions of female same-sex couples displayed a higher ‘yes’ vote. Higher turnout in the plebiscite benefitted the ‘yes’ vote. Finally, the views of the local MP on the issue were positively related to the result in their electorate.     

The Integration of VHR Satellite Imagery,GPR Survey and Boring for Archaeological Prospection at the Longcheng Site in Anhui Province,China

This paper is focused on the joint use of non‐invasive and minimal intervention techniques for supporting archaeological prospection. Very high resolution (VHR) satellite imagery analysis and ground‐penetrating radar (GPR) and boring surveys were integrated for the study of the Longcheng site, located near Hefei city in Anhui Province, China, to test their effectiveness and efficiency in prospecting archaeological remains and evaluating their degree of preservation. First, target locations of potential archaeological structures were identified on a WorldView‐2 (WV‐2) satellite image through spatial and radiometric enhancement, interpretation and object‐oriented classification. Second, archaeological features extracted from the WV‐2 imagery were further investigated by a GPR survey that provided detailed cross‐checking information about buried remains. Finally, a subsequent boring survey was conducted across those prospective archaeological structures in order to map the stratigraphic sequences on the basis of colour, compactness and the inclusions contained in the soil, and then to test their correspondence with the GPR data. The boring led to detailed confirmation of the results produced by the remote sensing analyses and GPR surveys, as well as the discovery of datable artefacts. On the basis of all the integrated data, the preliminary layout and structure of the Longcheng site was reconstructed in GIS. Furthermore, the widths, lengths, heights and burial depths of these buried archaeological structures were estimated in detail.     

A survey of the Nabataean/Roman Site,Umm at-Tawabin,Ghor as-Safi,Jordan

Umm at-Tawabin is an extensive Nabataean/Roman site overlooking Wadi al-‘Arabah in southern Jordan. The site, as a whole, consists of a number of buildings, circular stone structures, a roadway and other features that are fortified, for the most part, by a lengthy wall and with a predominance of Nabataean and Roman surface pottery on the ground. Up until now, the site has only been documented in brief in a handful of survey reports since its discovery in the late nineteenth century and its chronology has since been the subject of some conjecture among scholars. With a grant from the Palestine Exploration Fund, the author has sought to better understand the occupational history of this undoubted historically important site through survey and by extension, a study of its surface pottery and architectural remains.     

Mapping Qijiaping: New Work on the Type-Site of the Qijia Culture (2300–1500 B.C.) in Gansu Province,China

Recent work at the Qijia Culture type-site of Qijiaping in the Tao River valley of Gansu Province, China, has shed light on the complex nature of this early Bronze Age site. Situated at the intersection between the mixed pastoralists of eastern central Asia and the agriculturalists of China’s northern Central Plain, Qijia peoples absorbed, evolved, and transmitted products and technologies that shaped cultural developments in both directions. The Tao River Archaeological Project (TRAP) used a combination of surface survey, geophysics, digital mapping, and targeted excavation to expand our understanding of the multicomponent nature of Qijiaping. This included identifying potential habitation, mortuary, and production locales; examining site-wide ceramic use; mapping anomalies through geophysics; and further exploring these through targeted excavations. The results have expanded our knowledge of the site structure of Qijiaping and its place in the wider Qijia interaction sphere, while also confirming the usefulness of this methodology.     

Carta di cabotaggio del Mare Adriatico (1822–1824): A Turning-Point in the Development of Adriatic Maritime Cartography

After almost five centuries of development in nautical charts depicting the Adriatic Sea, a systematic, complete hydrographic survey was carried out that resulted in the first modern nautical chart of the area. The survey, a coordinated operation undertaken jointly by Austrian, Neapolitan and British experts in 1818–1819, was the first scientific activity in the Adriatic region to be based on international cooperation. Until then, the gathering, processing and presentation of geographical data on Adriatic nautical charts were neither systematic nor institutionalized activities, so those charts could not serve as reliable, safe sources of different types of information for seafarers and others for whom spatial relations in coastal, island and sea regions were of primary importance. Given the quality and quantity of hydrographical and geographical content presented in the Carta di cabotaggio del Mare Adriatico (Coasting Chart of the Adriatic Sea), it immediately became an essential source of spatial information.     

A Late Antique Ceramic Assemblage at Burgaz,Datça Peninsula,South‐west Turkey,and the ‘Normality of the Mixed Cargo’ in the Ancient Mediterranean

By combining underwater survey with formal and compositional study of ceramics, recent work at Burgaz (south‐west Turkey) reveals a late 6th‐ or 7th‐century assemblage of wine and perhaps other agricultural products carried in LR1 and LR2‐related amphoras. Representing various south‐east Aegean and likely Cilician producers, the mixed cargo aboard this probable shipwreck offers insights into the complex dynamics of seaborne distribution at the end of Antiquity. This brief study also underscores the need for documentation in underwater survey of amphora forms and fabrics, particularly those from a period characterized by intensified and diversified production of supra‐regional ceramic types.

The 2008 Maritime Heritage Assessment Survey along the Karpaz Peninsula,Cyprus

Since the arrival of Turkish military forces on the island of Cyprus in 1974, archaeological activity below the water in northern Cyprus has been virtually non‐existent. In August 2008, however, an international team conducted an underwater survey in this disputed region to document and assess the variety of maritime cultural heritage present along part of the coastline. This paper discusses the team's survey methods and goals, the discoveries, ranging in date from the 6th century BC to the 14th century AD, and plans for work in 2009. © 2009 The Author
