Eighteenth‐century England is, for many scholars, the time and place where modern domesticity was invented; the point at which ‘home’ became a key concept sustained by new literary imaginings and new social practices. But as gendered individuals, and certainly compared to women, men are notable for their absence in accounts of the eighteenth‐century domestic interior. In this essay, I examine the relationship between constructs of masculinity and meanings of home. During the eighteenth century, ‘home’ came to mean more than one's dwelling; it became a multi‐faceted state of being, encompassing the emotional, physical, moral and spatial. Masculinity intersected with domesticity at all levels and stages in its development. The nature of men's engagements with home were understood through a model of ‘oeconomy’, which brought together the home and the world, primarily through men's activities. Indeed, this essay proposes that attention to how this multi‐faceted eighteenth‐century ‘home’ was made in relation to masculinity shifts our understanding of home as a private and feminine space opposed to an ‘outside’ and public world.  相似文献

Accessibility is a fundamental but often neglected concept in transportation analysis and planning. Three complementary views of accessibility have evolved in the literature. The first is the constraints-oriented approach, best implemented by Hägerstrand's space-time prisms. The second perspective follows a spatial interaction framework and derives “attraction-accessibility measures” that compare destinations' attractiveness with the travel costs required. A third approach measures the benefit provided to individuals by the transportation/land-use system. This paper reconciles the three complementary approaches by deriving space-time accessibility and benefit measures that are consistent with the rigorous Weibull axiomatic framework for accessibility measures. This research also develops computational procedures for calculating these measures within network structures. This provides realistic accessibility measures that reflect the locations, distances, and travel velocities allowed by an urban transportation network. Since their computational burdens are reasonable, they can be applied at the urban scale using a GIS.  相似文献

The global concern about human-induced climatic change and its potential effect on sea-level has dominated the debate on coastal vulnerability, particularly since a common assessment methodology was developed by the Intergovernmental Panel on Climate Change in 1991. There have been numerous attempts to use or adapt this methodology but the focus has remained on sea-level rise as the single most important issue for coastal vulnerability. This paper presents a revised and more holistic coastal vulnerability assessment methodology which incorporates spatial and temporal scales relevant to the predicted impacts of climatic change and current human-induced hazards. Three studies in contrasting coastal environments of South Australia demonstrate that there are significant regional variations in sea-level response, human-induced hazards and local planning issues and that these may present a greater immediate threat than the possibility of sea-level rise.  相似文献

The classical traveling-salesman problem involves the establishment of a tour around a set of points in a plane such that each point is intersected only once and the circuit is of minimal total length. When the length of a salesman's tour cannot exceed a specified constant, the problem becomes that of finding the fewest number of salesmen such that every city is visited by a salesman and the length of each salesman's tour does not exceed a specified constant. This is the chromatic traveling-salesmen problem. An algorithm for this problem is developed and is used to create periodic markets in parts of Sierra Leone. Fifteen rural areas were examined from Sierra Leone, and weekly market places were identified in each area. Salesmen were to be assigned to an area so that each market place was visited and each tour (or periodic ring) did not exceed forty hours. The chromatic traveling-salesmen algorithm was used to minimize the number of periodic rings needed for each area and provide the specific tour for each ring.  相似文献

Remarkably little is known about the earliest surviving separate-sheet medieval map of Britain that takes its name from its former owner, Richard Gough (1735–1809), and that has been variously dated to between 1300 and 1400, and later. It presents a sophisticated cartographical image at a time when detailed maps of individual regions were almost unknown in Europe, yet nothing is agreed about its possible origins, context (ecclesiastical or secular), or why and how it was compiled. In the belief that historical interpretation has to stem from an intimate knowledge of the map as artefact—the state of the parchment, nature of the inks, palaeography—as well as image, an informal study group of historians and scientists (the Gough Map Panel) was convened in 2012 to examine the map through high resolution digital reproduction, hyperspectral analysis, three-dimensional analysis and Raman pigment analysis. Although the study is still ongoing, much that is new has been discovered, notably about the way features were marked on the map, Gough’s application to the map of a damaging reagent to render place-names readable, and the extent to which the original map (now dated to c.1400), although never completed, was nonetheless reworked on two different occasions in the fifteenth century, effectively creating two further maps. These and other findings are summarized here to encourage the further study of the map’s features that is needed before it can be fully understood.  相似文献
