The responsible government question in Natal, 1856–1893

ABSTRACT

The history of South Africa's Eastern Cape continues to attract considerable attention. Recent scholarship suggests that the Royal Engineers, as one of the executive arms of imperial colonisation, played a significant role in the colonisation and development of the eastern frontier of the Cape Colony. This article seeks to contribute to the discussion by examining the importance of surveying and mapping in underpinning and extending the colonial State in what is now the Eastern Cape. It attempts to disentangle and assess the impact of the activities of the Royal Engineers and other military officers. It briefly examines African responses to surveying and the construction of fortifications; and attempts to unravel the respective roles of imperial and colonial agencies in surveying, mapping, and construction of fortifications and establishment of towns.     

The application of the Submetrix ISIS 100 Swath Bathymetry system to the management of underwater sites

Over the last decade analysis of the HMS Pomone wreck scattered below the Needles has aimed to correlate artefact positions with their terrain and aid research into the distribution process of the wreck-site. However, physical limitations faced by divers on the site have restricted progress. The search for a solution to the difficulties of archaeological surveying was resolved by the Submetrix ISIS 100 system when a bathymetric survey of the wreck-site was performed in a single day. It has provided a contoured terrain model that can aid further investigations and help plans for the future management of the site.     

Precision GPS Surveying at Medieval Cottam,East Yorkshire,England

Abstract

To help promote the use of centimeter and sub-centimeter level GPS for surveying archaeological Sites, a series of tests was conducted at the deserted medieval village of Cottam in East Yorkshire,England. In order to understand the capabilities of the technology, the GPS system was tested for speed, accuracy, and reliability and the results were compared with those from a conventional total station. Using the capabilities of the total station as a benchmark, the GPS system's accuracy and reliability were found to be acceptable. The test system, however, was found to be considerably slower than the total station and much more difficult to use with equivalent levels of accuracy     

Changing roles,changing rules: procedural development and difference in Australian State upper houses

The status and potential of Australian State upper houses have been enhanced, to a greater or lesser degree from State to State, by electoral system change over the past half century. The purpose of this article is to determine the extent to which those changes have been accompanied by efforts on the part of the upper houses to improve performance of their core functions of review of legislation and scrutiny of government. The focus is the parliamentary procedures that facilitate performance of these functions. As well as surveying innovation in, and use of, relevant parliamentary procedures in the five upper houses, the article explains differential outcomes in innovation and effectiveness across the States in terms of the consequences of choice of electoral system and size of upper house membership.     

论陕甘宁边区婚姻立法原则的修正——以边区司法实践为视角

中国共产党在陕甘宁边区试图对旧有的婚姻观念和婚姻形态进行较为彻底的改造,在一系列婚姻立法中提出了新型的婚姻原则和婚姻制度。但是,婚姻制度的变革并不仅仅是新旧观念的简单变化,它的变革还应该包括经济、政治、文化等诸多社会制度的变革。因此,考察陕甘宁边区的实际婚姻状况,从司法实践中发现边区处理婚姻纠纷的原则、规则,不仅可以使我们全面了解边区司法机关在推行婚姻立法原则过程中所起到的重要作用,同时也为当今我国构建和谐社会、完善婚姻家庭制度提供了有益借鉴。     

内蒙古丰镇市双台山“大明洪武二十九年”石刻考释——兼论明代早期北边防御体系的转变

2007年,内蒙古长城资源调查队在调查乌兰察布一呼和浩特段明长城大边时发现一处石刻,刻于明洪武二十九年(1396年),主要记述了兴筑石刻附近长城的时间、修筑者、所修长城的起止位置及长度等,为研究这段明长城的修筑史提供了一份价值极高的文字资料。同时,明代洪武年间北边防御体系的建立与这段长城关系密切,长城与沿边卫所共同构成了点线结合的综合防御体系。永乐时期,明朝调整了北边防御战略,北边防线南撤,这段长城的作用逐渐减弱。

How incipient colonies create territory: the textual surveys of New Spain, 1520s–1620s

The study of colonial surveying and cartography has become key to understanding the history of European colonialism because of the recognition that land surveys and maps not only represent territory but form part of the process through which territory comes into being. While many studies have therefore focused on the history of instrumental surveying and cartography in New Spain, roughly equivalent to present-day Mexico, between the seventeenth and twentieth century, the textual surveys of the sixteenth century that helped to bring the initial colonial territory into being have gone largely unstudied. Content analysis of textual land surveys included in sixteenth-century viceregal land grants for sheep and cattle ranches demonstrates variation in references to distance, direction, and borders that begins to reveal a process of negotiation among local actors and centralized state power that was contingent on environmental, economic, and demographic differences between highland and lowland landscapes.     

Sacred,but not surveyed: Nineteenth‐century surveys of Palestine

Abstract

Nineteenth‐century Palestine mapping projects based on systematic land surveying reached a peak with the Ordnance Survey of Western Palestine between 1871 and 1877, conducted on behalf of the Palestine Exploration Fund by officers of the British Royal Engineering Corps. Various other nineteenth‐century proposals for an organized survey of the country—some of which bore partial results while others were never implemented—are also presented. The surveying of one region, Mesopotamia, during the 1830s and 1840s, forms the basis for the discussion of the reasons for the relative lateness of the topographical survey. The sacredness of the region seems not to have been a sufficiently convincing motive for entrepreneurs to organize and finance such a survey. The main reason for the delay in mapping the country as a whole was that it was not especially important, either strategically or geo‐politically, for the European nations engaged in the international struggles in the Middle East until the last quarter of the nineteenth century.     

Microdebitage analysis: Initial considerations

Microdebitage is defined as all stone flaking residue less than 1 mm in maximum dimension. Experimental replication indicates that it is produced in great quantities by stone tool manufacture and can permeate site matrices as a permanent signature of past cultural activity. Initial sampling studies suggest that microdebitage analysis may have considerable utility as a means of lithic site surveying.     

Enter the myopticon: Uncertain surveillance in the Danish asylum system (Respond to this article at http://www.therai.org.uk/at/debate)

Asylum seekers in Europe face increasingly restrictive policy regimes across the continent. In Denmark, they are held at designated asylum centres while their cases are processed and are subject to limitations on their movement, education and employment, as well as to a degree of surveillance from both the state and the Danish Red Cross, which operates the majority of the asylum centres. While these structures are in some ways reminiscent of Foucault's panopticon, I want to suggest a counterpoint to the panopticon, which I call the ‘myopticon’ to indicate the near‐sightedness of the central surveying eye. The myopticon is a near‐sighted system of surveillance practices, knowledges and sanctions, deployed as though it were panoptic. I want to suggest that the uncertainty that has soaked through the Danish asylum system and profoundly affected the asylum seekers in it is not a byproduct of bureaucratic processing, but intrinsic to the operation of the myopticon. By drawing out points of distinction with Foucault's panopticon, I sketch the outlines of a new technology of power that has powerful consequences for the daily lives of asylum seekers in Denmark.     

The Civic Survey of Greater London: social mapping,planners and urban space in the early twentieth century

This paper examines work conducted between 1915 and 1919 by a group of architects and planners based at the Royal Institute of British Architects. The project, called the Civic Survey of Greater London, and the substantial collection of maps and diagrams that resulted from it are currently unknown in histories of mapping and planning, thus this paper offers a preliminary account and analysis of the work. The paper begins by assessing the development of surveying and mapping techniques in the nineteenth century with the aim of situating the Survey within broader historical trajectories. The following section of the paper examines the immediate context for the Survey, in particular the place of Patrick Geddes and his ideas. The third part of the paper focuses on the work of the Survey itself. The fourth part draws out key analytical threads in dialogue with a number of the maps of the Survey. The emphasis placed here is on exploring lines of continuity between the Civic Survey of Greater London and earlier techniques of representation and governmentality. The concluding section reflects briefly on the reasons for the Survey's subsequent relative obscurity and the importance of the project for later traditions of surveying.
