The Chemical Composition and Production Area of Early Western Zhou Proto‐Porcelain Unearthed from Yejiashan Cemetery,Suizhou, China

The bodies and glazes of 27 early Western Zhou proto‐porcelain samples from Yejiashan cemetery, Hubei Province, were analysed using LA‐ICP–AES, SEM, XRD, a thermal expansion instrument and other analytical methods. The results indicated that the bodies of all samples were characterized by high silicon and low aluminium, and were made with porcelain stone raw materials found in the south of China. The glazes are typical of high‐temperature calcium glazes of the CaO (MgO) – K₂O (Na₂O) – Al₂O₃ – SiO₂ series, with relatively high Mn and P content, which was probably caused by the addition of plant ashes. The physical properties and phase compositions of Yejiashan proto‐porcelain show that firing processes were still in the early stages of development in ancient China. Multivariate statistical analyses indicated that Yejiashan proto‐porcelain might have come from the Deqing area, in Zhejiang Province. These results provide new archaeological evidence for research on issues related to material flow in the Western Zhou dynasty.     

Controlled Rocking CLT Walls for Buildings in Regions of Moderate Seismicity: Design Procedure and Numerical Collapse Assessment

Controlled rocking heavy timber walls are designed to rock on their foundations in response to earthquakes. For regions of moderate seismicity, it is proposed that this rocking behaviour can be adequately controlled using only post-tensioning, even with a large force-reduction factor and no supplemental energy dissipation. This article presents a force-based design procedure for controlled rocking cross-laminated timber walls without supplemental energy dissipation, including a method for estimating higher mode effects. Fragility analyses of three prototype walls demonstrate that the procedure can limit the probability of collapse to <10% during a maximum considered earthquake in a region of moderate seismicity.     

Documenting Archaeological Mortuary Features using High Dynamic Range (HDR) Imaging

This technical note presents a refined technique for photo‐documenting archaeological mortuary features using High Dynamic Range (HDR) imaging. Mortuary features in archaeological context can be complex and delicate given the wide variability in grave constructions and preservation of human skeletal remains. It is therefore critical to obtain the greatest detail possible when photo‐documenting these features. HDR techniques represent more contrast in photographs and provide greater detail across the DR of illumination within mortuary features—where complex arrangements of human remains can obscure or darken other elements or associated funerary objects, making them difficult to identify in traditional photographs. HDR can be employed with most standard digital single lens reflex cameras used for archaeological field projects, is easy to learn and employ (as described here), can be processed and produced with commonly used photo editing programs, and is ideal for use in unpredictable conditions that are often encountered with archaeological mortuary features and in field conditions.

Barrister gender and litigant success in the High Court of Australia

We examine the relationship between gender of the barrister and appeal outcomes on the High Court of Australia. We find that an appellant represented in oral argument by a female barrister, opposed to a respondent represented in oral argument by a male barrister, is less likely to receive a High Court justice's vote. However, we also find that the appellant disadvantage of having a female barrister present oral argument is (partially) offset in the case of liberal justices and on panels having a higher proportion of female justices. The extent to which the disadvantage is offset, and potentially turns from being a disadvantage to an advantage, depends on the degree to which the justice is liberal and the proportion of female justices on the panel.

本文探讨律师性别与诉讼结果之间的关系。我们发现这个过程并不对称。如果是由女律师上诉,而辩方是一个或一个以上男性律师,那么性别就是一个因素。不过并不存在相反的情况。我们具体发现,如果诉方是一个女律师,辩方为一男律师,诉方就不大可能获得最高法官的赞同。不过,我们还发现,如果法官具有自由主义精神,如果法官团的女性比例较高,那么女律师的不利情形就有可能被（部分地）抵消。被抵消的程度取决于法官自由精神的强弱,和法官团女性比例的大小。     

Real-Time Dynamic Hybrid Testing Coupling Finite Element and Shaking Table

In this article, a Simulink simulation block with the finite element function is developed on the basis of S-function and implemented as the numerical substructure of real-time dynamic hybrid testing. Thereby, a real-time dynamic hybrid testing system coupling finite element calculation and shaking table testing is achieved. Using the developed system, a shear frame mounted on the soil foundation is tested, in which the shear frame is simulated as the physical model and the foundation is simulated as the finite element model with 132 degrees of freedom. Several cases of the dynamic behavior of soil-structure interaction are studied.     

Identification of Suitable Limit States from Nonlinear Dynamic Analyses of Masonry Structures

Performance-based earthquake engineering, developed over the last decades for the design and assessment of other structures, can also be applied for masonry structures if the particularities of masonry are incorporated into the procedure. According to this methodology, structural performance can be assessed according to damage states which are identified through displacement/damage indicators. While various methods for the identification of limit states from the results of nonlinear static analyses exist, the identification of damage states from the results of nonlinear dynamic analyses is still uncertain. This article investigates a number of criteria allowing to identify the attainment of significant limit states from the results of time history analyses, in terms of appropriately identified response quantities. These criteria are applied to five building prototypes and their results are compared. A comparison with the limit states derived from nonlinear static analyses is also made.     

Effects of Different Record Selection Methods on the Transverse Seismic Response of a Bridge in South Western British Columbia

The seismic response of a continuous 4-span bridge designed according to the current Canadian seismic provisions is investigated using Incremental Dynamic Analysis (IDA). Different earthquake types, including shallow crustal events, interface Cascadia subduction, and deep inslab subduction are considered. The median collapse capacities calculated using different record selection methods including Conditional Mean Spectrum (CMS)-based, Uniform Hazard Spectrum (UHS)-based, and epsilon-based methods are compared. The use of the epsilon-based method generally resulted in the highest collapse capacity predictions, but the CMS-based method was less sensitive to the number of records considered in the IDA.     

美国西部牧区拓荒的牛仔与牧羊人

内战以后,美国的西部开发在第二次工业革命的推动下步入了新阶段。牧业开发是西部三大行业开发的重要组成部分之一。由于牛仔和牧羊人的艰苦开拓,西部崛起了“牧牛王国”和“牧羊帝国”。牛仔和牧羊人主要来自美国社会下层的劳动者和外国穷苦移民。他们是美国西部牧区的主要劳动力,是牧牛场主和牧羊主的雇工。他们的生活条件和工作环境非常艰苦,所承担的工作极为劳累、繁重和艰险。美国西部牧业的繁荣是他们艰苦创业和开拓进取的结果。牛仔和牧羊人都是牧区拓荒的先驱者和英雄。他们都对西部开拓做出了巨大贡献．佃长期以来,存美国却存存着褒杨牛仔和贬抑牧羊人的明显俪向．汶县栅不公诈的．
