ABSTRACT We develop an objective methodology for forming large regions (called macroregions) from small regions (microregions). We observe that the aggregation of microregions in an interregional input-output model causes aggregation error in the model. Our optimal regions are those that cause aggregation error to be minimized. We apply our methodology to Canada, and we compare our optimal regions for Canada to those of Statistics Canada and to those obtained using the well-known heuristic of Kossov. Statistics Canada's regions as well as those produced using Kossov's technique are characterized by substantially greater aggregation error than are those produced with our methodology. 相似文献

"The traditional view of the overall health field is criticized and a new perspective embracing the environment, life style, human biology and health care is presented. Spatial variations and distributional patterns in the UK of premature death from coronary artery disease in males and females, lung-bronchus cancer in males, cancer of the female breast, and 'All Causes' for both sexes are described and analysed at national, regional, district and intra-urban scale. High risk and low risk areas/communities for premature death from selected diseases are listed as indicators of local health status." 相似文献

Historians have recently turned their attention to the place of masculinity in the politics of early-modern England. This essay widens that exploration to include the imperial settings of Ireland and North America. Drawing upon a range of English- and Irish-language sources – including political treatises, maps, state papers and court poetry – it contends that manhood, as a relational value between men, helped structure the form and character of politics in the metropole, the kingdom of Ireland and the American colonies. In all of those settings, the definition of acceptable male behaviour was different, the effect being that political action and theory in each place took on unique features. Consequently, the essay cautions against studying England and its colonies as distinct units of historical analysis and calls for further exploration of the particularities of colonial settings and their influence on the imperial centre. Moreover, the essay aims to demonstrate that masculinity, particularly contest over its proper expression, is an agent in historical change, in this case helping to shape political theory and practice as England developed into a multiple monarchy and budding imperial power in the sixteenth and early seventeenth centuries. 相似文献

The term "apoplexy," which has been in use since antiquity, referred to a catastrophic illness with an abrupt loss of consciousness and a frequently fatal outcome. During the sixteenth and seventeenth centuries scholastic approaches that relied on authorities were merging with an observational approach to medicine and Galen's speculation that apoplexy was due to an accumulation of phlegm or black bile in the cerebral ventricles began to be seriously challenged. The most extensive collection of case reports with autopsies published in the seventeenth century was Theophile Bonet's Sepulchretum sive Anatomia Practica. Section 2 of Book I of the Sepulchretum contains 70 case reports of patients that died with the diagnosis of apoplexy. The scholia in this section provide an idea for the modern reader of the notions physicians had of apoplexy in the seventeenth century. The Sepulchretum was an important book for physicians of the late seventeenth and eighteenth centuries. It played an important role in the development of modern medicine and it was an important foundation for Morgagni's De Sedibus et Causis Morborum. This essay reviews the pathological findings reported in victims of apoplexy and examines the views concerning the symptomatology, pathogenesis, etiology, and treatment of this condition that were prevalent at that time. 相似文献

While much attention has been paid to the ways in which the private sector is now embedded within the field of development, one group of actors — for-profit development consultancies and contractors, or service providers — has received relatively little attention. This article analyses the growing role of for-profit consultancies and contractors in British aid delivery, which has been driven by two key trends: first, the outsourcing of managerial, audit and knowledge-management functions as part of efforts to bring private sector approaches and skills into public spending on aid; and second, the reconfiguration of aid spending towards markets and the private sector, and away from locally embedded, state-focused aid programming. The authors argue that both trends were launched under New Labour in the early 2000s, and super-charged under successive Conservative governments. The resulting entanglement means that the policies and practices of the UK government's aid agencies, and the interests and forms of for-profit service providers, are increasingly mutually constitutive. Amongst other implications, this shift acts to displace traditional forms of contestation and accountability of aid delivery. 相似文献

Archaeologists require precise chronologies of cultural change to understand the nature and timing, and causes and effects, of ecological and social transformations. The Uxbenká Archaeological Project (UAP) has made chronology building a main goal, employing epigraphic data, artifact seriation, and high-precision AMS 14C dating. With more than 60 14C dates with measurement errors below ±25 14C yr, primarily on single charcoal specimens, Uxbenká may be the most intensively dated Classic Period site in the tropical Maya Lowlands. Here we take the next step, combining this rich chronometric dataset with associated stratigraphic information in OxCal's Bayesian framework to generate a high-resolution chronology of Uxbenká's early development and expansion in southern Belize. We show how archaeologists may take advantage of complex architectural stratigraphy to constrain broad calibrated ranges during the Classic Period, and to estimate dates for observed construction events that can not be directly dated (e.g., clearing/leveling plazas, laying plaster floors, renovating/rebuilding structural elements). Our analysis confirms the antiquity of the ceremonial Stela Plaza (Group A), where first construction is estimated between 60 cal BC and cal AD 220 and is associated with a Pre-Classic structure obscured by later construction and reorientation of the group to a N-S alignment ca. AD 150–310. The analysis also indicates initial leveling and construction at plaza Group B from cal AD 60–310 and Group D from cal AD 20–240, both earlier than previously assumed. Though Late Classic contexts are not as well represented by direct dates, architectural modifications are documented at all three plaza groups after AD 550, including the extensive plastering, laying paving stones, and construction of facades on existing structures. The resulting chronology revises our previous thinking on the mode of settlement and development of Classic Maya society at Uxbenká and indicates specific areas of investigation to elucidate events in the Late and Terminal Classic at the site, including political and social fragmentation and the abandonment of the urban core late in the Classic Period. 相似文献
