An Applied Method for General Regional Seismic Loss Assessment—With A Case Study in Los Angeles County

We describe the formulation and application of an integrated general regional seismic loss assessment (RSLA) method for buildings in seismic regions. An efficient method for RSLA is valuable for engineers involved in city planning, risk management, and insurance dealings. In contrast to previously reported methods, the framework presented herein is hazard-based and utilizes a regional rapid seismic hazard deaggregation tool that allows regional assessment to be conducted more efficiently. The proposed technique is implemented as an example to assess general regional seismic loss in Los Angeles County for a ground motion hazard with 10% probability of exceedance in 50 years.     

The Serious Century and Hedayat's Grim Laughter

Perhaps inspired, more than anything else, by The Blind Owl's famous opening lines, the reception of the novel has so far been dominated by a dark view of the narrative. However, subtle inter-textual links and formal patterns in the narrative could help to read a radically subversive laughter in it which targets the novel's predecessors and readers equally and concurrently. This article engages the aesthetic qualities of the novel and attempts to account for and emphasize the literariness of the text in interpretation. By singling out a few inter-textual links and elaborating upon them in detail, the narrative's parodic laughter, its significance and the way it can change our appreciation of the novel are discussed.     

Iron Age tin bronze metallurgy at Marlik,Northern Iran: an analytical investigation

The archaeological excavations performed in 1961 and 1962 at the necropolis of Marlik (Gilan District, northern Iran) revealed important archaeological remains dating to Iron Age I and II periods (late second/early first millennium BCE). While the metal collection from Marlik includes various gold, silver and bronze objects and is considered one of the most significant finds of metal objects from the prehistoric Iran, the technological investigations discussed in this paper provide information on tin bronze objects only from Marlik. Both the composition and the microstructure of 25 copper alloy objects have been determined in order to achieve a better understanding of the metallurgical processes used in northern Iran from the second to the first millennium BCE. Experimental analyses were carried out using inductively coupled plasma mass spectrometry (ICP-MS), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM-EDS) and optical microscopy. The results demonstrated that the copper-base objects were made of the binary copper–tin alloy with variable tin contents. Other elements such as As, Ni, Pb, Zn and Sb were detected in minor/trace amounts. Variable tin content may be due to the application of an uncontrolled procedure to produce bronze alloy (e.g. co-smelting or cementation). Microscopic observations and microanalyses revealed the presence of numerous copper sulphide inclusions, lead globules and intermetallic phases scattered in the bronze solid solution. The microstructures seen in the bronze objects under study were varied and included worked/annealed or dendritic grain structures.     

The role of a Chaco-Era great house in the Southern Cibola Region of West-Central New Mexico: The Largo Gap great house community

Largo Gap is one of several late Pueblo II (a.d. 1050–1130) Chaco-style great houses located in the southern Cibola region of west-central New Mexico. This region is at the interface of two Southwestern cultural areas: Mogollon and Pueblo. We report results of survey and excavation research at the Largo Gap great house and associated community to explore the role great houses in this region served for local populations, as well as their articulation with other great houses across the “Chaco Sphere.” The results identify Largo Gap as an architecturally “Chacoan” structure and that use of this structure incorporated both Mogollon and Puebloan material culture. The use of ceramics from both ancestral culture groups indicates that the local community was multi-ethnic, and suggests a socially-integrative role for the great house within this region.     

Bronze alloy production during the Iron Age of Luristan: a multianalytical study on recently discovered bronze objects

Application of bronze alloy to produce artistic and religious artefacts was commonplace during the Iron Age in western Iran (1500–550 BC). These bronze artefacts are the so-called Luristan bronzes and have been found often from excavated graves and sanctuaries. The aim of this paper is to study on alloy composition and manufacturing process in some recently excavated objects from the Iron Age cemetery of Baba Jilan, northern Luristan. For this purpose, some objects were analysed by quantitative ICP-MS as well as microscopic studies by scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDS) and metallography methods. Also, some comparisons were carried out between Baba Jilan and other analysed bronze objects from Luristan in order to identify the metalworking process in bronze objects from the Iron Age of western Iran. The results showed that all Baba Jilan samples are made of binary copper-tin alloy. Tin content was variable in the composition of the samples. The variety of tin constituents proved that alloying has been performed by an uncontrolled process to produce bronze. The microscopic studies also showed that the manufacturing operations are similar in the Luristan bronzes. It was carried out to identify probable similarities in the bronze alloy production in the Iron Age of the Luristan region.     

Country Roads: Travel,Visibility, and Late Classic Settlement in the Southern Maya Mountains

Mayanist archaeology has long been concerned with creating and evaluating explanatory models for the locations of ancient sites relative to one another and to the physical geography of the Maya world. This study combines epigraphic data and spatial analyses to explore motivations for settlement location and to interrogate territorial strategies in Late Classic (a.d. 600–830) kingdoms in the southern Maya Mountains, around the modern towns of Dolores and Poptún, Guatemala. Least-cost path analyses were used to model natural travel corridors and their relationship with site location was assessed. In conjunction, viewshed analyses were applied to evaluate the importance of visual connections to likely travel routes. The results are considered in the context of the socio-politics and economics of the region, and raise questions about the character of and interconnections between travel, exchange, settlement location, and mechanisms for reinforcing territorial claims in the Late Classic Southern Maya Mountains.
