An error dating from 1885 in mapping the upper Strickland River, Papua New Guinea, was reinforced and extended by government officer Charles Karius in 1929 when reporting results from a lengthy exploratory patrol. Detailed maps produced by the US Army and the Royal Australian Survey Corps in, respectively, 1942 and 1966 perpetuated these errors. It was not until 1979, with release of a series of 1:100,000 topographic maps, that long-standing errors were finally put to rest. Throughout these years, the contributions of well-informed people tended to be ignored in favour of the opinions of those whose status implied authority.  相似文献

The data collected by the New Survey of London Life and Labour between 1928 and 1932 is one of the most significant resources of detailed household information for the interwar period, with data extracted for almost 30,000 households, providing detailed information including birthplaces, hours of work, and wages. This article assesses the process of the original data collection, highlighting issues that mean users of the extracted data must proceed with a measure of caution. In particular, it demonstrates that one investigator employed by the survey, who provided information for around a fifth of households, appears to have regularly submitted generic and estimated information that problematizes the dataset.  相似文献

From 1911 to 1914 an Anglo-Belgian boundary commission demarcated the 885 km boundary between the Belgian Congo and Northern Rhodesia along the watershed of the Congo and Zambezi rivers with a total of just 46 markers. Such low-density boundary demarcation with widely spaced pillars was typical of early British boundary-making in southern Africa. Less than fifteen years later, a second Anglo-Belgian boundary commission was created to re-demarcate the boundary. Not only was it unique for a colonial boundary in southern Africa to be re-demarcated, this second Anglo-Belgian boundary commission worked for six years with a budget that exceeded any previous British boundary commission in colonial Africa. This commission marked the Belgian Congo–Northern Rhodesia boundary on the ground with nearly five times the number of pillars as the first commission, literally etching the boundary in the African landscape. Its techniques of survey and boundary demarcation set a new standard, serving as a model for later British colonial boundary commissions and influencing boundary-making theory through the present day.  相似文献

Abstract

The Ordnance Survey's Boundary Survey, carried out between 1841 and 1888, was a major undertaking which resulted in the local administrative boundaries of the whole of Great Britain being reliably mapped for the first time. This was not achieved by imposition but by the use of local knowledge of boundaries, thus making permanent a communal memory of administrative geography and rendering it globally accessible through maps. The Boundary Survey aided the reform of local government areas, a process which started during the same period and provided derived data for the burgeoning collection of statistics in the nineteenth century.  相似文献

清康熙年间,阿拉善蒙古归附清廷后,与河西府(县)展开了长达数年的划界纷争。该文利用档案、地方志等相关文献资料,对清代河西走廊北部汉蒙交接地区的凉州、甘州二府与阿拉善蒙古边界纷争事件的过程、起因进行了详细考察,分析了在此事件处理过程中,国家与地方社会复杂而多元的互动关系。清代以来河西走廊北部边界的变迁,不仅折射出传统社会政治大环境的改变,而且也是区域农牧经济互动消长的反映。  相似文献

The aim of this study was to apply Nakamura's technique to Valencia city center, after some preliminary tests in Barcelona. Previous studies of Barcelona had measured periods in restrictive conditions and in various types of material ranging from very soft soil (with a predominant period of approximately 2 s) to rock (0.3 s), and under different measurement conditions. The Valencia city center measurements were taken by using the distance from buildings and car and pedestrian traffic to construct a measurement grid that was as regular as possible. We also estimated possible soil-structure interaction to detect potential vulnerability.  相似文献

Small farmers in the Crofting Counties receive relatively low prices for their store stock partly because most of them are bought by dealers. Dealers rather than farmers purchase the stores because they are marketed in small diverse lots and because many of them are sold at centres far removed from the main areas of demand. Suggested improvements in the marketing system include grouping stock prior to sale and selling them at large accessible markets rather than at small remote ones.  相似文献
