Logboats from Europe and the CD-ROM, or a solution to the endless search for documents (2000 edition)

Bibliographic data capture of logboats from Europe is available as a database which includes more than 6000 pictures or files (corresponding to the same number of A4 pages): as the result of the processing of 700 works dealing with 2400 logboats; 6500 links were established between those logboats and bibliographical references.     

Boats for Rivers and Mountains: Sources for New Narratives about River Travel?

What is a boat? Our notions of what constitutes a good boat are tested when it comes to logboats. They are often considered to be of low status, both technologically and functionally. However, logboats are more interesting than that. This article presents three logboats dated to the Roman era and late Viking age, found in the region of Telemark, Norway. The principal concern is to discuss how notions about prehistoric boats can be made known, challenged and discussed by examining the three boats in the context of the rivers and lakes in which they were most probably used. © 2007 Author     

Logboats from Bohemia and Moravia,Czech Republic

More than 40 logboats are known from the Czech Republic, and at least 20 are preserved in repositories or regional museums (seven in Moravia, 13 in Bohemia). Two further vessels remain in situ. Many logboats are known from neighbouring countries, but until recently vessels from the Czech Republic have not attracted the same research interest. Only five Czech vessels (two from Bohemia and three from Moravia) have been dated by absolute methods. Several more have been assigned tentative dates on the basis of context or close similarity to other dated vessels. This article presents a summary of current evidence. © 2009 The Author     

A Cognitive Approach to Extant Boat Structure in Goa,India

This article presents information derived from unfunded fieldwork undertaken between 2008 and 2014 in Goa, India. Traditional boat structure is understood in the context of the use of local materials in response to climatic, geophysical, and cultural factors. Expanded and unexpanded logboats are shown to affect differently the pirogues based on them. The outrigger is not used as a sailing aid. Small sailed boats with sewn strakes on a keel‐plank are compared with 19th‐century records. Simple techniques are used on larger sewn and metal‐fastened vessels still being built. Today some factors combine to compromise traditional construction, while others are bringing about the demise of the vessels themselves.     

Unfinished and Paired Logboats from Bavaria, Germany

Though Bavaria is far inland, at least 20 logboats are known, but only recently have some been properly recorded. This paper deals with two vessels discovered in the early 1990s. The remains at Laufen-Pfaffing represent a semi-manufactured logboat, which was purposely sunk as was the custom in Austria until the mid-20th century. The vessel from Wessobrunn-Blaik is also unfinished and shows several tool-marks. It is too narrow to float on its own: therefore it is part of a paired logboat. There is plenty of archaeological evidence for this kind of craft, but no ethnographic evidence. Apart from use as ferries, other uses are discussed.

The Hawārī of Socotra, Yemen

Hawārī are traditionally logboats carved from a single tree into a double-ended vessel which can be propelled by either sails or paddle. Hawārī can be found throughout the Indian Ocean from India through to East Africa, yet little is known about this ubiquitous vessel. The aims of this research are to address this lacuna in our knowledge by documenting the rich source of hawārī present on the island of Socotra, Yemen.

An Early Bronze Age Logboat from Degersee, Southern Germany

In 2004 the remains of a logboat were discovered in Degersee, a small lake near Lake Constance, southern Germany. Dating to the beginning of the 2nd millennium BC, it is an important find from a period with scarce archaeological evidence and only a few previously-known logboats. The vessel was situated in lake sediment and documented in situ . Our investigations can be linked to palaeo-environmental studies carried out at Degersee and adjacent lakes, and to palaeo-climatic research in the northern Alpine region. After investigation by underwater archaeologists the boat was moved to a sheltered place in deeper water.

A Neolithic Voyage

Examination of stone artefacts from Maiden Castle, Dorset, led to the identification of a Neolithic saddle-quern which originated in central Normandy. While stone axes from Brittany and jadeitite axes from the Alps have long been known from central southern England, the quern is the largest and heaviest Neolithic import yet identified. It has a bearing on the debate about indigenous or immigrant origins for the Neolithic, but also re-opens the question of the type of boat that plied the Channel at this early period. It is argued that logboats, for which there is evidence, should not be overlooked in favour of skin-boats for which there is none.

Silvio Berlusconi and the traditions of Italian foreign policy: a comment on Ambassador Romano's presentation

Abstract

While open to criticism on many levels, the foreign policy of Italy under Silvio Berlusconi does not deviate in many significant ways from traditional approaches, especially on its management of Italy's relations with the United States and the European Union. Italy's ‘exceptionalism’ is also similar to that of many other European states.     

The Potential Performance of Ancient Mediterranean Sailing Rigs

A common statement in the academic literature relating to the ancient Mediterranean is that the lateen/settee rig superseded the Mediterranean square‐sail because it provided superior upwind performance, greater manoeuvrability and higher overall speed. This statement has been repeated so often that it is now commonly accepted. Research by the author sets out to develop an insight into the relative performance of both types of rig, based on historical sources, ethnographic records and the performance of representative, full‐size sailing vessels. This allows a reassessment to be made of the underlying reasons behind the adoption of the lateen/settee rig in the Mediterranean. © 2010 The Author

The Mediterranean Lateen Sail in Late Antiquity

The Mediterranean lateen sailing rig has been studied since the early-to-mid-20th century. Recently-published depictions of sailing vessels rigged with lateen and settee sails, dating to the late-antique period, allow some of the principle characteristics of that rig to be established. This allows comparison with lateen- or settee-rigged vessels from both earlier and later periods. The sailing rigs depicted on other vessels can be identified and the level of technical continuity between the late-antique and medieval Mediterranean addressed. Finally it is possible to assess the extent to which the lateen sail was established in the Mediterranean by late antiquity.

Kelenderis Ship—Square or Lateen Sail?

The Kelenderis ship appears in a harbour scene frame that forms one-third of a mosaic floor (the other two-thirds are decorated with geometric patterns). The name of the ship indicates its location, the town once called Kelenderis, in Turkey. The large sailing ship is depicted with a fully-open quadrilateral sail. No anchor or mooring line is indicated, but its static position suggests that the vessel is at anchor. The purpose of this paper is to clarify the intricate type of sailing rig. The Kelenderis ship was researched in detail for the first time by Zaraza Friedman in her 2003 PhD dissertation.

Reflections on the Balance of Traditional Sailing Vessels

The balance of sailing vessels makes an important contribution to sailing characteristics, but its measurement is far from trivial. Traditionally, balance has been determined from the geometric centres of hulls and sails, but experimental results show that this approach is highly inaccurate. Designers overcome this difficulty by the use of a heuristic concept of 'lead', but the geometric methodology can be misleading in retrospective analysis of ancient sailing vessels. It can result in doubtful conclusions about sailing capabilities and incorrect deductions about the type of rig that was used and the reasons for specific mast positions.

饱水文物传统脱水方法与超临界流体干燥技术的应用

饱水文物的脱水加固是文物保护中的一个重要组成部分,为了克服干燥应力引起的文物结构的收缩和塌陷,传统脱水方法中常采用加填充剂浸渍等方法,从而使文物处理周期延长。超临界流体干燥技术利用气体在临界温度以上无论加多大压力都不能液化的特性,控制饱水文物内部的液体在临界点之上,使气/液界面消失,在无液相表面张力情况下进行的干燥过程。本工作在回顾传统饱水文物脱水加固的常用方法和存在问题的基础上,利用液体表面张力与温度的关系,从理论上解释超临界流体干燥技术用于干燥饱水文物具有能消除干燥应力的特点,介绍了国外学者利用该技术实际处理饱水文物时采用的实验装置、操作条件和干燥效果。与传统脱水方法对照,超临界流体干燥技术还具有能缩短文物处理周期、干燥过程中能同时杀菌等优点。

Traditional Retail Markets: The New Gentrification Frontier?

This paper presents traditional retail markets in the UK caught between a narrative of decline and revival, on the edge of a gentrification frontier. Traditional indoor and outdoor markets have become somewhat residual in many British cities but essential for many low‐income citizens that rely on their affordability. At the same time, the market is being reinvented for a wealthier type of customer interested more in local, environmentally friendly, ethical and “authentic” shopping experience. We take the case of Kirkgate Market in Leeds, the largest of its kind in Britain to analyse the process of disinvestment by the local authority, displacement of traders and customers and rebranding of the market for a new wealthier customer base. The paper is based on an action‐research project on which one of the authors is involved alongside traders and other campaigners to defend the public nature of Kirkgate Market in Leeds.     

共同体视角下民族旅游社区生产主体变迁研究——以岜沙苗寨为例

从旅游影响相关研究中存在"整体性"缺失和研究假设缺陷等问题出发,以共同体为研究视角和对象,以岜沙苗寨为案例展开历时性研究,采用定性分析方法,研究发现：首先,共同体的多元化是旅游发展后社区空间生产内在机制所发生的主要改变;其次,旅游发展后传统的社区共同体规则对社区空间生产路径起着保护作用,减弱了旅游对其传统文化的影响。最后：旅游作为导致民族社区变迁的外部原因之一,在逐渐加快其变迁路径的改变,对于在旅游发展的同时如何引导多元共同体规则的统一,从而保障其传统变迁路径的稳定,将是后续研究关注的重点。
