The Formative Period on the south coast of Peru: A critical review

Previous and current fieldwork has generated a significant body of data on the occupation of the south coast of Peru during the Formative Period (ca. 3800-2200 B.P.). These data are placed in a synthetic framework and evaluated and compared to the trajectory of cultural development in the better studied regions of the Central Andes. Critical review of this panorama necessitates consideration of the relative chronological framework and definition of the Formative Period, the parameters and validity of the south coast as a culture area, contacts south coast societies sustained with other Central Andean regions, and the role of monumental architecture in the rise of complex society.     

京津冀交通路网结构特征及其演变的分形刻画

交通一体化是京津冀协同发展的基础和前提，合理的交通网络结构对提升城市群整体效能意义重大。本文基于1995-2030年多源交通路网数据，运用分形思想，研究京津冀以城市群为节点体系的交通路网空间结构特征及演化趋势。主要结论如下：①京津冀高等级路网仍有一定扩展潜力，交通网络整体等级结构尚不稳定，未达到一种优化的分形递阶状态。②各级路网空间分布具有自仿射特征，但各向异性扩展强度正在逐渐减弱，城镇化和交通一体化战略的实施正在促进各级路网逐渐向自相似的结构一体化方向演化。③交通路网空间结构演化与城镇用地结构不同步，可能与系统所处城镇化发展阶段有关。④高等级路网分维演化服从次数大于1的logistic模型，按照规划预期，各级路网空间发育将相继在2040年前后达到饱和；但按照规划设计高速公路建设将过度饱和，未来应及时调整规划。     

Lead Isotope Analyses Revealed the Key Role of Chang'an in the Mirror Production and Distribution Network During the Han Dynasty

Chang'an (now Xi'an) was the capital of the Western Han Dynasty and the starting point of the Silk Road. In the light of the importance of Chang'an as the centre of politics, economy and cultural interaction, the overarching question proposed in this paper is focused on its role in the mirror production and distribution network during Han period. On the basis of chemical and lead isotopic analyses of 34 Han mirrors, this paper discusses the potential existence of a mirror production centre in Chang'an. Meanwhile, a comparative study with mirrors uncovered from the south‐western frontier and from Central Asian and North‐East Asian countries offers new insight into these related issues.     

European cultural diplomacy: diaspora relations with Kazakhstan

Abstract

Cultural diplomacy using diasporic communities as facilitators of interaction between states has long been important. This article suggests a typology of networks of communication derived from a case study of long-established diasporas living in post-independence Kazakhstan and their relationship with their European ‘homelands’. The typology juxtaposes the official stance of homeland governments expressed in formal and legal provisions with the lived experience of the diaspora communities. The study highlights the benefits of developing vibrant ‘valued’ networks of communication embracing both local diasporas and homeland embassies and agencies. In such cases, diplomatic benefits accrue to the homeland and local communities are empowered. Similarly, failing to capitalise on positive sentiment with some infrastructural support may leave an ‘expressive’ network as one of neglected potential.     

Application of Particle Motion Technique to Structural Modal Identification of Heritage Buildings

Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the adequacy of the characteristics of the structure. Most of the current structural identification techniques are based on linear methods that call for many measurement points and/or a relative simple structure. Complex structures are somewhat still an unexplored field due to the difficulties with the finite element method and the experimental corroboration of its results. This study presents the use of particle motion computation applied to each structural vibration mode to improve the identification of its dynamic properties, and its application to the Gothic Cathedral of Palma de Majorca (Spain).     

Young people's involvement in policy research

This article reviews the legacy of young people's involvement in policy research in the UK and proposes an approach of collaboration with young people that may be useful in other settings. It critiques the sociocultural and socioeconomic context relevant to young people's involvement in research, using the Young Researcher Network (YRN) as a case study. A key benefit of using the YRN has been the ability to identify and analyse potential barriers and facilitators influencing the relationships of young people and organisations whilst both groups worked together to improve policy. This allowed young people to connect to the policy environment in a meaningful way. The approach has been embedded into The Office for the Children's Commissioner in England, the National Institute for Health Research as well as other leading youth organisations in the UK, which is likely to increase the direct involvement of young people in policy research.     

Partnership Networks for Urban Development: How Structure is Shaped by Risk

In delivering public policy, governments worldwide increasingly partner with diverse sets of stakeholders. This spreads commercial risk, but particularly where agendas diverge, introduces new risks related to trust in relationships. The “risk hypothesis” distinguishes between networks for “cooperation” problems, where partners have high individual payoffs for uncooperative behaviors, and “coordination” problems, where partners subscribe to a common goal and uncooperative behaviors are less rewarding. We used mixed‐methods to study networks of local and state government, developers, and consultants that center on joint‐venture partnerships for developing new urban, residential projects. Statistical network methods showed that within the mix of partners involved in development projects, only state governments displayed structural patterns associated with solving “cooperation” problems (rather than coordination). In other words, the patterns of state government interactions showed they are most exposed to risky relationships. In contrast to the state governments’ apparent exposure to risk, qualitative data showed they are not only well trusted but also overall the partnership networks reported very low levels of conflict. By exploring the distribution of “cooperation” and “coordination,” we identified which stakeholders perceived most risk. In our case, how the state governments’ structure interactions in response to risky relationships leads to an overall network characterized by trust.     

曹魏薄葬考

曹魏时期的薄葬是相对秦汉厚葬而言,薄葬与厚葬在考古遗存上各有具体的体现,曹魏通过对汉代地面标记性设施和祭祀性设施、地下居室性设施和随葬明器的简省,开创了以薄葬为特征的新的丧葬模式,并影响着魏晋南北朝时期的丧葬。
