Political debate, even in medieval Europe, has often centred upon the relationship between individual liberties and the greater good. Fourteenth-century town councils had to think about protecting private property while ensuring the greater public good. The council registers of late medieval Marseilles offer the opportunity for insight into this public–private dichotomy through an examination of the council's decisions to suspend temporarily the execution of letters of marque. In fourteenth-century Marseilles, letters of marque helped citizens gain restitution from foreign debtors through a judicial authorisation to seize foreign assets. The suspensions, justified in the language of the utilitas publica, were declared for two reasons: to protect the integrity of the town's market by ensuring an ample supply of labourers and victuals, and to protect the town's honourable reputation when dignitaries visited. Study of these suspensions illustrates an overarching philosophy in urban government – that the public good must be safeguarded against private advantage.  相似文献

The dramatic decline in the integrity of Australian river systems in recent decades has seen the development of landcare and catchment management groups across the continent as the main facilitators of river rehabilitation works. There is growing concern for the need to develop adaptive management frameworks that assist informed decision making through the integration of social and geomorphological knowledge into catchment planning. In the Mulgrave River Catchment of northeastern Queensland, difficult management decisions have to be made with limited access to knowledge of natural processes and baseline geomorphological data. To date management decisions have been based almost exclusively on oral histories that state that point bars are accreting and the river is becoming shallower due to bank erosion. As a result bank stabilisation and removal of sand from within the channel have been recommended in the absence of any geomorphological assessments. This study compares oral histories of river bank erosion in the Mulgrave River with geomorphic evidence to highlight the need for integrated landscape scenario planning. The results of grain size analysis of bank and bed material from 27 locations, involving 47 samples, suggest that bank erosion cannot be delivering sediments to point bars. Furthermore, qualitative analysis of historic parish maps and aerial photographs shows that there has only been moderate bank erosion at three locations along the Mulgrave River since European settlement. The study demonstrates the important role that geomorphological investigations have for catchment management and the need for management frameworks that integrate geomorphological processes and landholder priorities for sustainable river management.  相似文献

Very few early Chinese shipwrecks have been discovered in Southeast Asia, despite the enormous volume of trade with China. This article describes the surprising hull features of one such wreck, and its diverse ceramic cargo. The Bakau Wreck dates to the early 15th century, and was bound from southern China to Indonesia via a Thai entrepot port.  相似文献

In Tysfjord Municipality, North Norway, written sources mention Sami farms in the sixteenth and seventeenth centuries. The farms had a mixed economy, with an emphasis on agriculture, fishing, hunting and gathering. On some of these farms there are documented settlement mounds. Minor excavations have been carried out on several of these archaeological sites. A pollen sample has also been taken from one of these locations. By using radiocarbon dating and artefact analyses it is possible to date the settlement mounds back to the Early Middle Ages. The establishment of these cultural monuments documents a change in the economy, with animal husbandry becoming more important. During the Middle Ages, cultivation of barley arose as a new element of the economy. The article addresses the question of whether this change in the economy can be linked to a Sami or a Norwegian population.  相似文献

十一届三中全会后农村经济改革的成功主要归功于家庭承包经营的实行和推广,但同时也应看到一些尚被人们忽视的重要因素——国家在这一时期采取提高粮食收购价、限定粮食征购数量而扩大进口粮食等特殊政策,为农民多劳多得的承包积极性提供了持续的推动力和可行条件。另外,从生产力决定生产关系的基本原理考察,"四三方案"引进大化肥成套设备的投产,成倍地增加了单位化肥施用量;籼型杂交水稻和高产小麦的研制成功和推广,将粮食亩产大幅度增加,都使得农村经济改革如虎添翼,取得了粮食产量连上新台阶的巨大成就。这些因素共同促使新时期农村经济改革顺利进行并最终取得成功。  相似文献

The applicability of a post‐infrared infrared stimulated luminescence (pIRIR290) protocol and two different thermoluminescence (TL) protocols—a single aliquot regeneration (SAR) and a multiple aliquot additive dose (MAAD)—was tested on six polymineral fine‐grain (4–11 μm) samples extracted from the wall remains of a Roman lime kiln and a Roman roof tile. These remains had been excavated close to Bergisch Gladbach, which was at that time part of Germania magna. For the pIRIR290 measurements, no dependence of De on first‐stimulation temperature was detectable, and the standard first stimulation temperature at 50°C was adopted. Fading tests and dose‐recovery tests were made for all samples. Background subtracted glow curves were recorded up to 480°C for TL after a preheat of 220°C for 120 s. A‐values were determined for all TL and pIRIR measurements. The results for all three protocols were fairly consistent, and TL and pIRIR290 protocols are shown to be suitable to estimate reliable equivalent doses for the fired kiln walls. The resulting ages are in agreement with the expected time range—Roman Iron Age—and with independent age control provided by radiocarbon ages of animal bones and charcoal from the firing chamber.  相似文献

Abstract

Beetle (Coleoptera) pests of stored products such as the granary weevil may have entered the archaeological record by various routes, including: (1) deliberate dumping, and usually burial, of spoilt grain with the aim of preventing further infestation of grain in storage; (2) the use of infested grain as human and animal food; (3) the incorporation of infested grain and living or dead grain pests into deposits by accident and by reworking. It is suggested that these routes, although outlined specifically for beetle grain pests, can stand as a model for the way other insects and biological remains became incorporated into the archaeological record. It also is suggested that the identification of these different depositional routes depends strongly on taking a multi-proxy (‘indicator group’ or ‘indicator package’) approach to the archaeological and biological record of urban sites.  相似文献

An American specialist on Russian agriculture examines that country's agrarian policy, as well as the agricultural sector more generally, one year into the presidency of Dmitriy Medvedev. Focusing on the three key policy issues—state financial support, state intervention in the grain market, and international food trade policy—he assesses the extent to which current policy represents a continuation of that prevailing during the presidency of Vladimir Putin. The author discusses the appointment of a new Agriculture Minister in 2009, which may signal a different approach to the management of the sector, and concludes with an assessment of the impact of the global financial crisis.

Plant residues recovered from prehistoric stone artifacts can be used to help explain tool function and plant use. At the Changning site in Qinghai Province, Northwest China, dating from 4000 yr BP, we examined starch granules extracted from three slate stone knives. A total of 153 starch grains were retrieved from three stone knives, from which we identified starches from legumes, the Triticeae tribe, foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), roots and tubers. These results indicate that the stone knives may have been used for a variety of activities that included reaping grasses and food processing. The species of starch grains retrieved from the study sample reveal that diverse crops were cultivated at the Changning site 4000 years ago.  相似文献

元明清时期,京杭大运河的开通,便利了北方政治中心与南方经济中心之间的联系。特别是在明清时期,大运河漕运事关国计。当时政府的诸多治河措施是为确保漕运畅通,加之明代保陵的需要,更使黄河、淮河、运河之间的关系复杂化。封建政府的决策行为使本自独流入海的淮河改道主要由长江入海,使淮河流域成为十年九灾之区。  相似文献
