Much of the literature examining the effects of oil shocks asks the question “What is an oil shock?” and has concluded that oil‐price increases are asymmetric in their effects on the U.S. economy. That is, sharp increases in oil prices affect economic activity adversely, but sharp decreases in oil prices have no effect. We reconsider the directional symmetry of oil‐price shocks by addressing the question “Where is an oil shock?” the answer to which reveals a great deal of spatial/directional asymmetry across states. Although most states have typical responses to oil‐price shocks—they are affected by positive shocks only—the rest experience either negative shocks only (five states), both positive and negative shocks (five states), or neither shock (five states).  相似文献

Using adjusted 2000 population census data, this paper conducts projections of China's population up to 2050. Three fertility and four mortality scenarios yield 12 sets of results. Even though fertility is below replacement, China's population will continue growing for many years. One of the notable trends is the rapid ageing of the population. By the end of 2050, one-fifth to one-third of China's population will be aged 65 and over. The demographic dividend is expected to continue in next 10 to 20 years depending on future fertility which, in turn, is determined by changes in China's one-child policy. The Chinese government should be aware of all possible situations of population change, and particularly population ageing in the first half of the century, and be well prepared for all possible challenges that may arise.  相似文献

The paper examines potential changes in housework and employment among married couples in Japan. The data are from national surveys in 1994 and 2000 of persons aged 20–49. Wives’ housework hours decreased and the proportion of husbands doing any housework increased. A majority of wives are employed, many work full-time and husbands work long hours and many return home late in the evening. While wives do less housework if they are employed, husbands’ housework does not respond to their wives’ employment. Large gender differences persist, with wives’ employment associated with family constraints. In general, changes were the same across categories of the population, though three of five significant interactions with time involved wives’ education. A positive relationship between wives’ education and any housework by husbands becomes stronger over time. The results suggest gender inequality in housework may decrease in the future, with potential relevance to future marriage and fertility.  相似文献

Ivan Jablonka seeks something other than a mere combination of history, social science, and literature. He would like history, itself understood as a social science, to be a literature of the real world. He is also interested in literature informed not only by the results but, more important, by the forms of reasoning and inquiry of history and related social sciences (notably anthropology and sociology). Jablonka's own positioning within the Annales seems obvious, notably in his stress on cognition, problem‐oriented research, and the status of history as a social science. But the attention and research devoted in the work of scholars in and around the Annales to the relations among history, literature, and fiction have not been pronounced, and in this context Jablonka inflects the understanding of history in relatively underdeveloped directions. Despite possible disagreements one may have over specific issues, Jablonka's thought‐provoking book raises very important questions, opens many significant avenues of inquiry, and seeks a desirable interaction between historical and literary approaches.  相似文献

Global social, political, and economic change during the past quarter-century has been profound, particularly in major areas with languages different from those usually employed by Canadian geographers. Surveys by the author suggest that senior Canadian geography graduate students, however, are inadequately prepared to assimilate primary world sources of information, including the relevant research literatures (except those published in this country's two official languages), and that few geography departments any longer require competence in more than one language at any level of study. Nevertheless, geographers and their students could benefit in many ways from foreign language expertise. Suggestions are made whereby geography departments could reinforce their existing rigorous training programs with foreign linguistic and area competence.  相似文献

ABSTRACT This paper examines the determinants of total factor productivity (TFP) using a GB plant‐level data set. The main findings relate to whether spatial spillovers and “place” effects are important: plants located in cities generally perform better than plants in the same region outside of these cities; but with the exception of Bristol, no city has significantly higher TFP levels than the South East. This suggests that spatial externalities associated with city location are not as important as the benefits of being situated in the South East region.  相似文献

ABSTRACT This paper reviews what we know about the spatial manifestations of knowledge. The knowledge production function addresses the easily measured portion of knowledge produced. Research on learning, particularly interactive and collective learning, in firms and in innovation systems, promises to unveil the human and organizational processes by which knowledge is created, stored, and transmitted to others. Our understanding of innovation and technological change depends on how well we tackle knowledge and its geography.  相似文献

In the Slingram electromagnetic method the appropriate coil orientation must be chosen. Until now, the choice of this parameter has not been discussed but as it influences the shape of the anomalies and their magnitude, it is important to try to define the best possible arrangement. Theoretical studies of the 1D layered model, the response of a dipole and the response of a 3D body are used to define the best arrangement. The perpendicular configuration with a vertical moment transmitter gives better results in most cases and the building of an apparatus with this coil arrangement should give very interesting results.  相似文献

Recognizing that post-modernism (broadly defined) has had a significant impact upon contemporary geographical practice, this essay considers the claims of its proponents and seeks to weigh the implications of the postmodernist impulse for the subject as a whole. On balance, recent engagements with the ideas of a broad spectrum of important philosophers and critical theorists are seen to have broadened, enlivened, and in some respects enhanced human geography. The impress upon physical geography has been much less consequential. Yet many post-modernist claims must be met with circumspection. Embraced tout ensemble, they would seem to blinker understanding, limit practical engagement with the world, and imperil the foundations upon which important geographical work has been (and should continue to be) built. In human as well as physical geography, different scales of inquiry favour (even require) different modes of analysis, and a respectful understanding of different scholarly aims and means is essential if Geography is to remain robust well into the new millen nium. Étant donné que le postmodernisme (au sens large) a beaucoup influé sur les pratiques de la géographie contemporaine, cet essai étudie les affirmations de ses partisans et cherche àévaluer les implications du post-modernisme pour la discipline dans sa totalité. En fin de compte, l'utilisation des idées de toute une gamme de philosophes importants et de théoriciens du post-modernisme peut être perçue comme ayant élargi et à certains égards amélioré la géographie humaine. L'impact du postmodernisme sur la géographie physique a été beaucoup moins important. Et pourtant, on doit envisager avec beaucoup de prudence les prétentions des partisans du postmodernisme. Si l'on accepte toutes ces théories dans leur ensemble, on risque de mettre en cause notre compréhension du monde et de nuire aux fondements mêmes sur lesquels la recherche en géographie a été (et continuera àêtre) construite. En géographie humaine aussi bien qu'en géographie physique, l'échelle des recherches entreprises implique (et même nécessite) l'utilisation de différentes méthodes d'analyse. Une compréhension respectueuse des différents objectifs et méthodes des chercheurs en géographie est essentielle, si nous voulons que la géographie en tant que discipline maintienne sa vigueur au-delà du seuil du nouveau millénaire.  相似文献

ABSTRACT Spatial econometrics has been criticized by some economists because some model specifications have been driven by data‐analytic considerations rather than having a firm foundation in economic theory. In particular, this applies to the so‐called W matrix, which is integral to the structure of endogenous and exogenous spatial lags, and to spatial error processes, and which are almost the sine qua non of spatial econometrics. Moreover, it has been suggested that the significance of a spatially lagged dependent variable involving W may be misleading, since it may be simply picking up the effects of omitted spatially dependent variables, incorrectly suggesting the existence of a spillover mechanism. In this paper, we review the theoretical and empirical rationale for network dependence and spatial externalities as embodied in spatially lagged variables, arguing that failing to acknowledge their presence at least leads to biased inference, can be a cause of inconsistent estimation, and leads to an incorrect understanding of true causal processes.  相似文献

To test how crime affects economic activity, we use point‐specific data on crime, commercial property sales and assessed values from New York City, relying on an instrumental variables strategy. We find that crime reduces commercial property values, and the magnitude of the effect depends on the type and geography of crime. Elasticities range from ?0.1 to ?0.5. We find stronger evidence for negative violent crime effects in neighborhoods with lower incomes and higher shares of minority residents. Thus, disadvantaged neighborhoods are doubly harmed by crime—they have higher crime rates and those crimes have stronger effects on economic activity.  相似文献

Alon Confino has issued a desideratum to other historians that they should bring questions and insights from cultural history to bear on the study of the Holocaust. Taking the work of Saul Friedländer as his point of departure, Confino nonetheless sets out on a path different from Friedländer's. He turns away from the goal of “integrated history” and instead seeks to investigate the realm of German culture, understood as encompassing much more than just Nazi ideology. By analyzing how the Holocaust has come to be perceived as unprecedented, as a rupture in human history, and furthermore by treating Jewish victims' sense of disbelief as an artifact of the past, one that has continued to inform unduly the historical understanding of the Holocaust up to the present day, historians will be able to account anew for what made the persecution and extermination of Jews imaginable and thus possible. With Confino's approach, a major historiographical question resurfaces, however: namely, what place an analysis of non‐Germans should occupy in the history of the Holocaust, and in particular what place should be accorded to Jewish voices? This essay argues that we cannot make sense of why Germans supported and carried out the Holocaust without also considering Jewish contemporaneous perspectives and imaginings.  相似文献

This article reviews two edited volumes on fear, important contributions to the newly developing field of the history of emotions. The question at the center of Jan Plamper and Benjamin Lazier's volume is how fear is constituted as an object; this question is investigated in an interdisciplinary dialogue. Focusing on the twentieth century, the editors bring together psychologists, historians of science and of emotions, and specialists in literature studies, politics, and film. Taking the dialogue beyond the social sciences is certainly an exciting and necessary exercise, but it also raises the question whether both sides are really talking about the same object. Michael Laffan and Max Weiss place fear in a global history perspective. They cover a wide scope, from early modernity to the present, and geographically including the Americas and Indonesia. Taken together, both volumes not only give an impressive overview of the field of fear studies, and add to it through a number of case studies, but also raise the question “what object is fear?” in a new way. If this object is as fluid as appears from the two volumes—not only with respect to the different events that trigger fear, the different uses it was put to, and the politics it allowed, but as a felt emotion—this calls for further investigation notably into the words and concepts used to make sense of the experience.  相似文献
