The measurement and interpretation of spatial economic structure have presented many problems for analysts. The notion of a spatial multiplier has received even less formal attention; part of the motivation for this paper is the examination of the degree to which sectoral decomposition analysis might prove useful in illuminating the paths of interaction across space that are associated with changes in exogenous activity levels. In this paper, we present three perspectives that examine spatial structure in the context of an aggregated interregional social accounting matrix for Bangladesh. These perspectives examine structure at the micro-, meso-, and macrolevels and are interpreted with the assistance of several alternative methods, including structural path analysis, the field of influence, the superposition principle, multiregional feedback loop analysis, and the Matrioshka Principle; the results are interpreted analytically and cartographically. Some attention is also devoted to the formulation of a general approach to spatial multipliers. It is shown that the structure of flows and the structure of influence reveal patterns that, taken together, provide important insights into an understanding of structure and may prove to form the basis for the eventual formal presentation of the spatial multiplier.  相似文献

The sophistication of regional economic models has been demonstrated in numerous ways, most recently in the form of linking several modeling systems or in the expansion in the number of equations that can be manipulated successfully to produce impact analyses or forecasts. In this paper, an alternative perspective is employed. What do regional macro-level forecasts indicate about the process of structural change? A new methodology is illustrated that enables analysts to make forecasts of detailed structural change in the interindustry relations in an economy. Using a regional econometric input-output model developed for the Chicago metropolitan region, derived input-output tables are extracted for the period 1975–2016. These tables are then analyzed to determine the forecasted direction of structural changes for the region. The innovation illustrated here is based on a model that exploits the general equilibrium spirit of computable general equilibrium models through the adjustment of input coefficients to clear markets.  相似文献

Philip of Novara, a writer of Frankish Outremer, is notable primarily for the variety of his works, in which he gives ample evidence of a close acquaintance with a large body of medieval French literature. His aesthetic concerns stand him in good stead when he comes to construct his history of the wars between Frederick II of Hohenstaufen and the supporters of John of Ibelin, for the narrative he produces is remarkably coherent and well-organized. However, such is his interest in imaginative literature in particular that on occasion he chooses to neglect his responsibilities as a historian. In his account Philip includes a number of poems, and it would seem that the real circumstances of their composition have been obscured in order to justify their presence in what is supposed to be a record of authentic, experienced events. Similarly, in certain of the speeches Philip attributes to John of Ibelin, historical truth is sacrificed even more readily than is usual in favour of purely literary considerations.  相似文献

ABSTRACT

Compared to other gorget styles and themes made during the Mississippian period, the so-called rattlesnake gorgets of eastern Tennessee have been found in fairly large numbers. Stylistically, Muller assigned these gorgets to the temporally related Lick Creek and Citico styles, while Crawford’s recent work has argued for substyles within. While their style has been studied extensively, the idea that these gorgets depict rattlesnakes generally has been accepted without further consideration. In this paper, we present the results of a systematic iconographic study of rattlesnake gorgets. Ultimately, we conclude that the image’s original referent is not just a snake but instead is intended to be a model of the cosmos at night.  相似文献

Women's everyday experiences in war remain occluded; moreover, the bodily impacts of war remain hidden, masked by masculinist accounts of warfare that too often glorify heroic male combatants. In this article, we contribute, first, to the ongoing project to understand violence in everyday life and, second, to the understanding, specifically, of women's experiences in warfare. We do so through a reading of the diaries of Dang Thuy Tram, a female Vietnamese doctor who lived and died in the Vietnam War. By drawing on feminist geopolitics, coupled with the insights from emotional geographies – and specifically, those of love – we focus on two main themes: the emotional transformation of death and life, and the care of life amidst pervasive death. We conclude that an emotionally grounded feminist geopolitics is necessary to challenge masculinist accounts that normalize, naturalize, and glorify war.  相似文献
