Floor Response Spectra for Bare and Infilled Reinforced Concrete Frames

The objective of this article is to study the effects of structural nonlinear behavior on Floor Response Spectra (FRS) of existing reinforced concrete frames. This study examines how the FRS vary with the level of post-elastic behavior in buildings of different number of stories and masonry infill wall configurations. The effect of damping modeling assumptions is also investigated. Differences and similarities with findings from the literature are discussed. On the basis of the obtained results, a commentary on the adequacy of basic assumptions used in predictive equations proposed by different seismic codes is offered.     

Dual Energy Computed Tomography for the Non‐destructive Analysis of Ancient Ceramics

Ceramics are usually the most common artefact found on any ancient archaeological site. Compositional analysis of this pottery, and characterization of the clay fabrics from which they are made, has the potential to pinpoint sources of manufacture as well as identify trade routes and consumption patterns in the ancient world. Currently, most analytical techniques require the partial or total destruction of the ceramic sample. This research investigates the use of dual energy computed tomography (DECT) to analyse Black Gloss and Vesuvian Sigillata from Pompeii. The results indicate that DECT may be a viable adjunct or alternative to conventional analytical techniques. Importantly, unlike traditional methods, DECT is totally non‐destructive, a highly significant factor when analysing irreplaceable artefacts.     

基于扎根理论的美国游客中国意象研究

旅游目的地意象是入境游客对目的地认知的核心内容,也是其对外传播中国形象的主要载体.本文以旅华美国游客为研究对象,以旅游目的地意象为研究内容,通过4批次全程客流跟踪的调研方式获取了开放式语句资料.采用扎根理论的研究方法,开放式编码抽取了旅华美国游客对中国意象认知的11个主范畴,主轴编码构建了典范模型,继而开发了入境游客目的地意象认知的故事线.研究结果表明：旅游吸引物、自然环境、人文环境及社会特征是游客目的地意象形成的因果条件;目的地所提供的各项旅游服务以及人际互动成为重要的中介条件;目的地意象形成的主要脉络是情感涉入;游客的目的地城市意象会刺激并促使游客产生行为意图.     

An Anatomy of the London Agent

This article considers the London agent through the careers of Gilbert Mabbott and, to a lesser extent, William Raylton. The London agent was a commonplace in early modern political culture, but the phenomenon is rarely addressed in the historiography. I argue for the importance of the agent to early modern English history in general, but I also consider Mabbott's situation in particular. Because of the civil wars, Mabbott was able to rise beyond his social station as a scrivener and freed himself from the bonds of the patron‐client relationship. This article seeks to define some of the roles played by agents in the early modern period by looking at Mabbott's and Raylton's work for their major employers: Thomas Wentworth, Hull, royalist delinquents and their children, various parliamentary armies, and Oliver Cromwell. It ends by looking at the wealth that Mabbott acquired through his work, both before and after the Restoration, as demonstrative of how an agent's power could yield impressive rewards when freed of social constraints.
