从宁波工艺品公司案看我国法院对涉外仲裁协议的监督

国家法院对仲裁协议实施监督的核心问题,就是仲裁协议的效力和仲裁庭管辖权的认定：在仲裁程序开始之前,法院就应当根据另一方当事人的请求,令当事人将协议项下的事项提交仲裁解决,除非法院认定仲裁协议无效、失效,或者不能履行;在仲裁程序开始之后,法院仍然有权根据一方当事人的请求对仲裁协议有效性和仲裁庭的管辖权问题进行审理,法院的此项权力来源于法院地国的国内法;在仲裁程序结束之后,当事人还可以裁决所依据的仲裁协议无效为由,申请法院撤销此根据无效仲裁协议作出的裁决,或者拒绝承认与执行此裁决。但如果当事人在仲裁程序中放弃了对仲裁协议有效性或者仲裁庭的管辖权提出异议的权利,则当事人在裁决作出就不能再以仲裁协议无效或者仲裁庭对仲裁协议项下的争议没有管辖权为由,请求法院撤销或者拒绝执行此仲裁裁决。     

Skeletal Indicators of Shark Feeding on Human Remains: Evidence from Florida Forensic Anthropology Cases

This research examines a series of six Florida forensic anthropology cases that exhibit taphonomic evidence of marine deposition and shark‐feeding activities. In each case, we analyzed patterns of trauma/damage on the skeletal remains (e.g., sharp‐force bone gouges and punctures) and possible mechanisms by which they were inflicted during shark predation/scavenging. In some cases, shark teeth were embedded in the remains; in the absence of this evidence, we measured interdental distance from defects in the bone to estimate shark body length, as well as to draw inferences about the potential species responsible. We discuss similarities and differences among the cases and make comparisons to literature documenting diagnostic shark‐inflicted damage to human remains from nearby regions. We find that the majority of cases potentially involve bull or tiger sharks scavenging the remains of previously deceased, adult male individuals. This scavenging results in a distinctive taphonomic signature including incised gouges in cortical bone.     

A Comparison of US and Japanese Dental Restorative Care Present on Service Members Recovered from the WWII Era

The documentation of dental materials used in the USA during the WWII era is readily available, while references for the Japanese are minimal. It was therefore important to build a photographic database of Japanese restorative care which could be utilized as a comparison tool for the deployed odontologist. The dental restorative care of approximately 400 US and 100 Japanese sets of remains was evaluated. Both countries share many similar restorative techniques to include collared crowns, full‐coverage restorations, cantilever bridge/pontics to close spaces; restorative materials such as amalgam, gold, and zinc phosphate (temporary) restorations; and removable prostheses. The dental restorative materials most commonly used by US dentists include the amalgam and silicate cement, while the full‐coverage crown was the type of restoration most frequently seen on the Japanese remains. Silicates, porcelain and replaceable crowns, and partial‐coverage prepared crowns were not observed on the recovered Japanese remains.
