Plant microfossils in prehistoric archaeological deposits from Yuku rock shelter,Western Highlands,Papua New Guinea

Plant microfossil analysis was carried out on anthropogenic deposits from Yuku rock shelter, possibly occupied from before 14,200 cal. BP to recent times, in the Papua New Guinea Highlands. Elaeocarpus pollen has extremely high percentages throughout. Starch residues of lesser yam (Dioscorea esculenta) and one or more, undifferentiated Dioscorea species were identified, suggesting processing of these taxa since first use of the site. The latter include Dioscorea alata, Dioscorea bulbifera, Dioscorea nummularia and Dioscorea pentaphylla. Pollen and phytoliths of banana (Musa) appear 5200 cal. BP. We cannot differentiate between naturally growing and cultivated yams and bananas. Putative truffle (hypogeous Ascomycotina) spores in the deposits suggest foraging of truffles.     

Temporary organisations and spatial embeddedness of learning and knowledge creation

It is the overall aim of this article to investigate theoretically how spatial embeddedness of learning and knowledge creation might be challenged by alternative organisational forms (i.e. temporary organisations). The article presents development coalitions as an alternative to projects as a form of temporary organisation. They are potentially able to combine the promotion of radical change with collective and localised learning, thus eliminating some of the characteristic shortcomings of project organizations with regard to collective learning and transfer of knowledge.     

‘The debatable territory where geology and archaeology meet’: reassessing the early archaeobotanical work of Clement Reid and Arthur Lyell at Roman Silchester

The first large-scale archaeobotanical study in Britain, conducted from 1899 to 1909 by Clement Reid and Arthur Lyell at Silchester, provided the first evidence for the introduction of Roman plant foods to Britain, yet the findings have thus far remained unverified. This paper presents a reassessment of these archaeobotanical remains, now stored as part of the Silchester Collection in Reading Museum. The documentary evidence for the Silchester study is summarised, before the results are presented for over a 1000 plant remains including an assessment of preservation, identification and modern contamination. The dataset includes both evidence for the presence of nationally rare plant foods, such as medlar, and several archaeophytes. The methodologies and original interpretations of Reid and Lyell's study are reassessed in light of current archaeobotanical knowledge. Spatial and contextual patterns in the distribution of plant foods and ornamental taxa are also explored. Finally, the legacy of the study for the development of archaeobotany in the 20th century is evaluated.     

Interventions on Europe's political futures

Europe is facing challenging times. The so-called ‘migration crisis’ has seen the hardening and militarisation of Europe’s borders. Nationalist politicians are framing European states as being under siege from Islamist terrorists and economic migrants, which has led to a rise in xenophobia and casual racism on the streets of European cities. Meanwhile the Euro-zone has seen a series of employment crises and economic bailouts. Alongside such political and economic turmoil, the European Union is facing unprecedented pressures, not least from the ‘Brexit’ result of the UK's referendum on EU membership in June 2016. In reflecting on these manifold challenges to the idea and space of Europe these interventions focus on three themes that have long animated political geography scholarship: borders, power and crises. Cross-cutting the interventions are two calls to action: to rethink our analytical approaches to Europe, and to reframe our role as critical scholars.     

The Resinous Cargo of the Java Sea Wreck

A number of blocks of resinous materials were found in the cargo of a 12th‐ to 13th‐century shipwreck, discovered in the late 1980s in the Java Sea near the Indonesian islands of Sumatra and Java and excavated in 1996. These well‐preserved blocks presumably were trade materials used for religious, medicinal, cosmetic, decorative or practical purposes. Such materials, derived from plants and termed exudates, generally include frankincense, myrrh, ‘gum benjamin’, liquidambar, dragon's blood, dammar, copal and amber. The source of the cargo resin could not be determined from the site. Investigation by nuclear magnetic resonance (NMR) spectroscopy has revealed that the molecular structure corresponds to that of modern resin from the plant family Dipterocarpaceae, known in trade as dammar and closely resembling Group B copal and amber. Other molecular classes of exudates are excluded. Such materials are not present in the Middle East, which then cannot be their source. The NMR spectra differ from those of Group B samples from Australia, Papua New Guinea and Indonesia, but resemble those from India or Japan. The spectra indicate that the saline environment had a similar effect on the molecular structure to heating and aging.     

植物对土遗址的保护作用初探——以内蒙古东部地区土遗址为例

位于内蒙古东部的土遗址上普遍长有植物,由于植物本身对土遗址具有双重作用,既有保护作用,也有破坏作用,采用植物保护土遗址就是最大限度的发挥其有利的一面,故此研究植物在遗址中发挥的保护作用尤为重要.选择应昌路故城、元上都遗址和辽上京遗址作为研究对象,采用现场调查的方法从植被覆盖度、根系分布情况两方面研究植物对土遗址的作用.结果表明,遗址顶面普遍被以羊草、冰草、紫羊茅、马蔺、旋覆花为主的低矮草本植物覆盖,其覆盖度集中在30％～60％;这些植物对防止降水冲刷遗址有明显的作用,对遗址的整体外貌影响也比较小.因此,针对长有植被、雨蚀病害严重、其他保护手段技术还不成熟、达不到理想的保护效果的遗址,可采用植物保护土遗址,并且其思路是可行的.     

旅游者权力对旅游者满意影响的实证研究——感知控制的中介作用及消费经验的调节作用

近年来,由于旅游信息可获得性不断提高等因素,旅游者的消费者权力日益增加,并被研究者所关注。本文从旅游者自身的角度探索了其权力行使对满意的影响及作用机制。研究结果显示：权力不仅能够有效地减少旅游者权益受损经历,而且能显著地提升其对消费经历的控制感和满意度。进一步研究发现,在这个过程中感知控制起到了部分中介作用,旅游者的消费经验正向调节权力与感知控制及权力与满意之间的关系。本文实证检验了以往消费者权力和增权研究的基础假设,为其理论体系提供了数据支持,并且为旅游者提供了法律以外的、维护自身权益和获取消费满意的主动性手段。     

Mendicants as victims: scale,scope and the idiom of violence

This article establishes the scale of violence perpetrated against mendicant friars in thirteenth- and fourteenth-century Europe, and provides a list of these events in an on-line appendix. It underscores and analyses the wide variety of contexts in which such incidents took place and examines the ramifications for the history of the mendicant orders and medieval urban society generally. Violence was a subtler form of communicative action than is sometimes recognised, and the paper points to the inverse relationship between power and violence in medieval urban conflicts.     

日俄战争期间美国的东北亚政策

本文认为,美国在日俄战争期间的东北亚政策仍然是坚持“门户开放”,但是在实现目标的手段上有了微妙的变化:着重在东北亚推动和构建“均势”格局——挺日、拒俄,建立均势,而不再是前一时期的“追随”欧洲列强,嗣机插足的政策。
