Abstract

Accessibility is frequently used in transportation planning to measure the efficiency of new infrastructure in terms of travel time and population served. In this article, the authors apply accessibility concepts based on the geo-historical angle. The aim of this study is to investigate the relationships between population dynamics and the railway expansion from 1830 to 1930. Their approach considers a local scale composed of some 36,000 French communes for the demographic data and more than 28,000 kilometers for the railway network. The methodological framework of this database is based on historical geographic information systems completed by anamorphosis analysis. In this way, they are able to map the changing contours of accessibility from the local to the regional and national scales for historical time.  相似文献

'Bioregionalism' is a term referring to an action-oriented movement based on ecological principles. It has not been strong in academic geography, though it clearly has space and place as its concerns. From a merging of classical regional geography and general systems one might have expected a bioregional synthesis to emerge. The bio-regional ideal can be given rigorous expression in a regional system comprising three sub-systems - a biophysical sub-system, an inhabiting sub-system, and a network sub-system.
Le mot 'biorégionalisme' s'attache à un mouvement ďaction et de pensée écologiste. Peu representé au sein de la géographie 'officielle, ii a néanmoins des rapports avec le problématique de ľespace et des lieux. On aurait du attendre que la convergence de la géographie régionale classique et ľétude des systèmes nous ameneraient à un synthèse 'biorégional.'Ľesprit biorégional peut s'exprimer ďune façon rigoureuse sous forme ďun système régional, comprenant trois sous-systèmes - sous-système biophysique, sous-système ďhabitat, et sous-système des liaisons et des réseaux.  相似文献

In our politico-philosophical bestiary, no monster has historically been more prominent than the Leviathan, the whale of the Book of Job, transformed by Hobbes, which has long been ubiquitous as a metaphor or as a signifier in all intellectual traditions touching upon the political. Like the state itself, we argue, the Leviathan has played an outsized role in the way we theorize and imagine relations of sovereignty in the world. This essay seeks to add a new hermeneutical creature to the bestiary: the Kraken. Said to be huge and to lurk in Norway's icy waters, the Kraken first emerged in the accounts of natural philosophers in the eighteenth century, at the very moment when political economy was becoming the premier science of governance in Europe. Leviathan is an emblem of a kind of state that no longer exists and has never existed, and it remains our most potent emblem of the state's reification, a relentlessly compelling figure that has long blinded historians to alternate sovereignties within, across, and outside the physical territories of states. From stateless financial capital to multinational corporations acting like states on the world stage, such forms of sovereignty are an essential feature of the global politics we are now living. These forms are not new, nor is their emblem: the Kraken.  相似文献

To date, no satisfactory account of the connection between natural‐scientific and historical explanation has been given, and philosophers seem to have largely given up on the problem. This paper is an attempt to resolve this old issue and to sort out and clarify some areas of historical explanation by developing and applying a method that will be called “pragmatic explication” involving the construction of definitions that are justified on pragmatic grounds. Explanations in general can be divided into “dynamic” and “static” explanations, which are those that essentially require relations across time and those that do not, respectively. The problem of assimilating historical explanations concerns dynamic explanation, so a general analysis of dynamic explanation that captures both the structure of natural‐scientific and historical explanation is offered. This is done in three stages: In the first stage, pragmatic explication is introduced and compared to other philosophical methods of explication. In the second stage pragmatic explication is used to tie together a series of definitions that are introduced in order to establish an account of explanation. This involves an investigation of the conditions that play the role in historiography that laws and statistical regularities play in the natural sciences. The essay argues that in the natural sciences, as well as in history, the model of explanation presented represents the aims and overarching structure of actual causal explanations offered in those disciplines. In the third stage the system arrived at in the preceding stage is filled in with conditions available to and relevant for historical inquiry. Further, the nature and treatment of causes in history and everyday life are explored and related to the system being proposed. This in turn makes room for a view connecting aspects of historical explanation and what we generally take to be causal relations.  相似文献

We examine the contribution to economic growth of entrepreneurial marketplace information within a regional endogenous growth framework. Entrepreneurs are posited to provide an input to economic growth through the information revealed by their successes and failures. We empirically identify this information source with the regional variation in establishment births and deaths. To account for the potential endogeneity caused by forward‐looking entrepreneurs, we utilize instruments based on historic mining activity. We find that the information spillover component of local establishment birth and death rates have significant positive effects on subsequent entrepreneurship and employment growth for U.S. counties and metropolitan areas.  相似文献

This essay celebrates the publication of Duress, explores its concepts and themes, focuses on the way Ann Stoler rejects the notion of historical forgetting and develops a heuristic of “colonial aphasia” in an ethnographic chapter on the emergence of France's Far Right near Marseille in the 1990s. The essay also tracks how postcolonial scholars are using the notion of aphasia, drawing on Stoler's colonial usages in contexts like the Netherlands and Britain as well as using the notion to periodize. Those who came to aphasia before and without Stoler are also present here, and their contributions suggest a range of ways to think through radical, countercultural, and philosophical thought. That Gilles Deleuze and Paolo Virno use aphasia in contrary ways suggests that once aphasia departs from clinical settings, its poetics are rather up for grabs even if contained within activist gestures; both rethink matters of politics, dissent, and language. The example of Kurt Goldstein is also imported to show that clinical aphasia may go with the “detours” of patients, those stricken by war, catastrophe, and these peculiar speech disorders. That “detour” is also a Deleuzian word opens wide a “minor” register to history, speech, and forms of oppression. The semantic spectrum for aphasia in histories of politics and language is wide, from Stoler's colonial version that applies most to the privileged, to Deleuze's poetic transpositions that propose aphasia as an accomplishment, a rebellious refusal of communication. Aphasia has much promise as a historical category in and outside of colonial forms of duress.  相似文献

Gorman proposes to investigate historical practice under the rubric of a philosophy of disciplines. Such philosophy must first “recover historically” the self‐constitution of the discipline in order then to appraise its procedures for warranting claims. Gorman's concept of discipline would have profited from consulting the substantial body of empirical research and theory regarding disciplinarity, and his “historical recovery” of the discipline of history leaves a lot to be desired. These insufficiencies vitiate the interesting arguments he has to offer concerning the question of the truth‐claims of whole historical accounts. A better reconstruction of disciplinarity might also have provided him with stronger rejoinders to the postmodern challenge to historical practice that he sees himself called to rebut.  相似文献

This research applies a task‐based approach to measure and interpret changes in the employment structure of the 168 largest U.S. cities in the period 1990–2009. As a result of technological change some tasks can be placed at distance, while others require proximity. We construct a measure of task connectivity to investigate which tasks are more likely to require proximity relative to others. Our results suggest that cities with higher shares of connected tasks experienced higher employment growth. This result is robust to a variety of other explanations including industry composition, routinization, and the complementarity between skills and cities.  相似文献

In this book Anton Froeyman has provided us with a colorful and intriguing account of a Levinasian approach to historical inquiry and historical writing. In my discussion of his book I describe central features of his account and notice how he uses, to develop his view, recent developments in historiography—including the work of figures like Natalie Davis and Carlo Ginzburg, in philosophical thinking about history and historiography, and in various postmodern developments. I sketch central features of Levinas's ethical metaphysics and show that Froeyman's focus on Levinas's interest in our relations with other persons and in particular with their relative differences from us is too narrow. A proper understanding of our infinite responsibility to and for all others, as Levinas portrays it, leads to a broader account than the one Froeyman gives and one that enables us to understand with greater clarity how historiography fits into the Levinasian understanding of our temporal and interpersonal relations with others.  相似文献

We propose an urban search‐matching model with land development. Wages, unemployment, prices of housing and land are endogenously determined. We characterize the steady‐state equilibrium and then discuss the issue of efficiency. To explore interactions among markets, we implement comparative static analysis. We also consider three policies: an entry‐cost policy that reduces firms' entry, a transportation policy that reduces commuting costs, and a housing policy that decreases rental prices. We find that the transportation and housing policies are more efficient if the unemployment rate is low, while the entry‐cost policy is more efficient if the unemployment rate is high.  相似文献

THEORIES, PARADIGMS, MAPPING, AND GEOMORPHOLOGY   总被引:1,自引:0,他引:1  
A past-president's address is a unique opportunity to reflect on one's experience in a discipline or to examine that discipline with a critical eye. This is best done during the brashness of youth or from the comfortable position of maturity. Obviously it is from the latter vantage point that I wish to probe this branch of science, geomorphology, which for twenty years has given me renewed intellectual challenges, beauty that only a field scientist has the privilege to behold, physical difficulties which result in a minimum of middle-age bulge, and lessons in humility which keep proposed explanations honest.  相似文献

According to a popular view, the past is present here and now. This is presentism combined with endurantism: the past continuously persists through time to the present. By contrast, I argue that memories, memorials, and histories are of entities discontinuous with present experiences, and that the continuity between past and present in them is a construct. Memories, memorials, and histories are semantic means for dealing with the past. My presupposition that past and present are different is supported by grammar: as verbal tenses show, the past is not present here and now, for otherwise it would not be past. A failure to note this difference is a lack of chronesthesia, a sense of time specific to human beings. I argue that presentism fails to account for the temporal structures of memory and the changes in perspective as we switch from the present to a past situation. My account is perdurantist in the sense that it allows for temporal parts of things such as memorials or tombstones, as well as events such as wars or commemorations. But my main goal is to outline a semantic approach to the past: the tie between past and present actions and events is the semantic ground–consequence relation: a past event is the antecedent grounding a present situation, explaining why it is the case. In addition, I show how we refer to the past by means of two rhetorical figures of speech: synecdoche, using the (emblematic‐) part‐whole relation for relating the past to the present by transposing its sense; and anaphor, which has a deictic function—it points back toward the past. In references to the past, the deictic field is a scene visualized by the speaker and addressees: the deictic field is transposed from a perceptual to an imaginary space.  相似文献
