An Approach to the Diagnosis of Craniofacial Fibrous Dysplasia from the 2500‐Year‐Old Remains of a Skull from Ancient China

A human skull, buried about 2500 years ago in a Bronze Age cemetery at Jinggouzi, a site of an important ethnic group in ancient China, appeared to have characteristics of fibrous dysplasia. The CT images indicated a reduction in bone density and relatively homogeneous lesions. More features were revealed using CT reconstruction techniques. Lesions seen in low‐magnification images using a 3D deep‐field microscope had an irregular honeycomb‐like structure. At higher magnification, the trabeculae morphology and the gaps between the trabeculae were irregular and varied in size and shape. Paraffin‐embedded specimens stained with HE showed trabeculae with tortuous irregular arrangements varying in shape and width. The irregular trabeculae of woven bone has been described as having fibrous dysplasia. Molecular analysis of the GNAS gene indicated no mutation. This provides a non‐invasive approach for us to make more comprehensive diagnoses and to assist research into ancient human diseases.     

Making waves: the valuation of innovations in San Sebastian’s surf economy

This study takes a valuation perspective to study how and where products and innovations are gaining ‘economic significance’ in the contemporary economy. Building on a recent research stream in economic geography and urban and regional studies, it highlights that the economic value of many products is not formed within production systems alone, but relies on co-constructed connections between production and consumption systems, playing out across multiple geographies. It distinguishes between three types of economic valuation pathways – namely technical, experiential and identity-based – which although analytically distinct may actually build and reinforce one another. This approach is empirically illustrated with the case of the surf-related economy in the city of San Sebastian (Basque Country, Spain), which is used to make a broader point about the growing relevance of a valuation approach to understand competitive advantage and economic renewal in localized production systems.     

A High-Performance Quadrilateral Flat Shell Element for Seismic Collapse Simulation of Tall Buildings and Its Implementation in OpenSees

Shear walls are important lateral force-resistant components of tall buildings. Hence, a reliable numerical model that can accurately represent the mechanical characteristics and large deformations of shear walls is critical for realistic collapse simulation of tall buildings. Based on the theory of generalized conforming element, a high-performance quadrilateral flat shell element, NLDKGQ, accounting for the large deformation using the updated Lagrangian formulation, is proposed herein and implemented in OpenSees. The reliability of NLDKGQ is validated using classical benchmark problems and reinforced concrete specimens. In addition, its capability in simulating the collapse of a tall building is also demonstrated.     

Earthquake Resilience of Reinforced Concrete Structural Walls with Replaceable “Fuses”

The concept of providing a fuse in a structural system has been both developed and investigated over the past few years (e.g., the use of replaceable links in eccentrically braced frames or the use of replaceable links in the new San Francisco-Oakland Bay Bridge). This paper presents a new coupling beam with a creative fuse installed in the mid-span of a steel-concrete composite beam via an end plate and high-strength bolts. First, a practical design methodology of a replaceable coupling beam is presented. Next, the seismic behavior of the proposed fuse is tested and evaluated, and two structural wall specimens with or without a fuse are designed and fabricated according to the proposed design methods. The two specimens possess similar shear capacities under large-scale cyclic loading, and the walls of the two specimens show similar failure modes; however, the new walls exhibit slightly lower levels of damage than the conventional walls. In particular, the inelastic deformation and damage of replaceable coupling beams are mainly concentrated in the fuse, whereas the non-yield segment and the beam-wall pier interfaces remain nearly intact and produce only slight damage, which is beneficial regarding the replacement of the fuse in post-earthquake events.     

Establishing a ‘Cultural Base’? The Creation of the Fulbright Program in Portugal

This paper deals with the cultural and educational relations between the United States and Portugal during the Cold War. It is built upon the premise that cultural policies and cultural relations between states are a fundamental part of international relations. History of International Relations, therefore, should overcome an analysis based only upon political and diplomatic dimensions to address what can also be referred to as ‘cultural diplomacy’. The Cold War period, because of its historical features, is particularly relevant to the study of processes of cultural diplomacy and some authors even consider it as the ‘golden age’ of cultural diplomacy.¹1.

渤海上京城出土金属及冶炼遗物科技分析

通过使用便携式荧光光谱分析仪（p-XRF）、扫描电子显微镜与能谱（SEM-EDS）等对渤海上京城宫城、匠造址、东廊、御花园出土的铁质遗物、有色金属遗物以及冶炼废弃遗物进行了初步研究,并对渤海上京城所进行的金属冶炼工业流程进行推演,同时试图通过遗物本身对渤海国冶金生产技术及商贸流通提供部分佐证。     

溯源与新解:论文物古迹“原状”

"原状"认识来源于西方经典保护理论,历经启蒙运动、法国大革命和反修复等社会运动。至19世纪,其思想内涵不断发生变化,从单纯地强调"原物""原状"发展到将历史真实的"原状"观念扩大到历史时间和"环境"等更大的对象范畴。20世纪以来,经典保护理论走向成熟,"原状"也真正从追求"原物真实"走向了传递其蕴含的"价值意义"。"不改变原状"是我国文物古迹保护的核心原则,经历了"初建时的原状""整旧如旧"、对于"原状"的多元释义、"体现价值的状态"等四个阶段。文化遗产的保护要从原物、原信息、原地点、原场所精神、原用途五个方面综合考虑"原状",才能真正保护好遗产的价值。     

参与性收藏的理论探析与思考

参与性收藏是近些年来西方一些博物馆基于"记录今天"理念而新兴的收藏。从收藏的角度,参与性收藏是博物馆通过主题策划与活动设计,组织社会公众携相关物件加入博物馆收藏,并成为馆藏的一部分,以参与的方式将公众与博物馆物品、内容、语境联系起来,其主题多与当下社会发展、生产生活方式变迁等相关,方式上突破传统收藏相对单一、封闭的模式,具有流动、共享、多元、充满活力的特点。从藏品内涵上,具有"记录今天""关注日常""突出藏品与人的关联"等特点,丰富了博物馆藏品的内涵与外延,这是对传统收藏的丰富与推进。在参与性收藏的视野下,航海类博物馆收藏具有更深广的创新空间。     

Dental and oral nonmetric traits in a Coimbra reference sample: testing intrasample chronological and spatial variation

A reference sample of dental and oral nonmetric traits should represent its biological population from which it stems. The presence of individuals born at different times, different regions, and separate countries in the Coimbra-identified cranial collections provides the test of whether this sample reflects the biological continuity of this Portuguese sample among the late modern (early industrialization, nineteenth century) to early contemporary (early demographic transition, first half of the twentieth century) population of this region of central Portugal. The Coimbra collections were scored for 61 traits using methodology by Hauser and De Stefano (1989), Turner et al. (1991), Scott and Turner (1997), Irish (1998), and Marado and Silva (2016). The 600 individuals in the sample were divided by generation, region, and nationality. Their phenetic diversity was tested with principal component analysis and with the mean measure of divergence statistic. The proximity between the subsamples was generalized, and it mimicked previous genetic marker results. Some small subsamples hindered conclusions; nevertheless, this Coimbra sample is considered a reliable dental reference sample for the Portuguese late modern/early contemporary population.
