Correlations Between Frequency Content Indicators of Strong Ground Motions and PGV

The frequency content of ground motions seems to be one of the most important parameters to explain the structural damage experienced during worldwide strong earthquakes. The frequency content of ground motions can be characterized by various stochastic and/or deterministic indicators: the frequency bandwidth indicator ? (Cartwright & Longuet-Higgins) related to the power spectral density function and, respectively, the control (corner) period T_c of the structural response spectra or the mean period T_M . Peak ground velocity (PGV) and the ratio PGA/PGV can be used as either damage potential parameters or frequency content indicators. A comparative analysis of stochastic and deterministic frequency content indicators and of PGV is applied to a set of 30 strong ground motion records having peak ground acceleration (PGA) from 0.2–0.8 g and recorded on 4 continents during the last 70 years.

‘Startling; Nay,Almost Repulsive’: Light Effects and Nascent Sensation in John Everett Millais’s The Rescue

Taking Pre-Raphaelite painter John Everett Millais’s The Rescue (1855) as a case study of shifting aesthetic and moral frameworks, the essay investigates the ways in which mid-century British debates regarding the proper representation of light effects illuminate anxieties about a physically embodied viewer, one who encountered pictures in individualized ways that required regulation and guidance. Represented light, as an element that had a measurable effect on the senses, clearly stimulated a physical response and therefore brought the body to the fore in the art encounter. Types of painting that forcefully engaged the somatic self could become suspect and consequently subject to a process by which they were designated as ‘sensation’, a category in fraught relation with the disappearing ‘sublime’. Combining close visual analysis, a discussion of The Rescue’s novel subject matter, remarks by its first beholders, and nineteenth-century aesthetic theory, the article reflects on the ways in which discourses of art revealed anxieties about the formation of the modern subject and argues that The Rescue is a node in which the death of the sublime meets the birth of sensation.     

解放战争时期妇女职业状况考察

1945—1949年．随着解放战争的进行。中国职业妇女状况发生了较大变化：在国民党统治区,由于国民党独裁统治的加强和财政经济的崩溃,妇女就业机会、职业环境和生活待遇不仅没有得到较好改善．反而恶化,导致了广大职业妇女的普遍反抗：在共产党解放区．伴随解放区的扩大．农妇获得了土地所有权,成了纺织运动的主力。以女工为代表的女职工也得到了广泛的职业平等权．从而展示了中国职业妇女解放的道路。     

青岛物流产业发展的空间竞争研究

物流是在网络信息技术支持之下,由运输、仓储、包装、装卸、加工和配送等环节所组成的,有形物品从产出源地到最终消费地的流动仓储活动。物流产业是推动地区经济发展的新型服务产业,是社会分工深化的结果。通过构建国际物流流程模型,探索港口城市国际物流的运作机制和一般规律;通过对三大港口城市进行港口-腹地关系的对比分析,揭示青岛物流产业发展所面临的国际和国内竞争;最后,结合青岛在区位、水深、腹地以及港口设施等方面的优势,提出青岛物流产业发展的方向及对策。

Urban geoarchaeology and environmental history at the Lost City of the Pyramids,Giza: synthesis and review

Sediment accretion in ancient urban sites and tells records a combination of cultural and geomorphic processes. Urban geoarchaeology is focused on site accumulation, collapse, weathering and erosion, as constrained by architectural plans and structures. These may document settlement growth and decay, as well as environmental history, posing a multidisciplinary challenge of interactive and fluctuating processes.     

胡适《读吕氏春秋》的贡献

写于1930年,后收入《胡适文存三集》卷三的《读吕氏春秋》,是胡适的一篇研究《吕氏春秋》的论文。该文打破了有汉以来研究《吕氏春秋》只重视文本解释的局限,采用了中西比较的思路与方法,从人欲、人性的思想高度审视把握《吕氏春秋》,提出了不少现在看来仍不失为有价值的观点与问题。文章视野开阔,论从史出,文风明白晓畅,易于接受,方法与结论都令人耳目一新,初步改变了以后《吕氏春秋》研究的路向,在近代《吕氏春秋》研究史上具有开拓之功。
