Given the common use of chemical concentration data to define ceramic groups that aid in the exploration of ancient technology, trade and provenance, it is important to reflect on how we collectively establish and define both chemical groups and outliers. In this paper, we argue that commonly used data analysis procedures, such as principal component analysis and centred log‐ratio principal component analysis favoured in the examination of ceramic chemical data, although rapid and easy, may overlook existing chemical groups and outliers, especially when the ratio of non‐diagnostic to diagnostic elements is high. To evaluate whether geochemistry is more important than data dispersion in data assessment, we re‐examine chemical concentration data from previously published ceramic, clay and daub samples from the lower Ohio River Valley. We begin by briefly discussing steps we took to ensure that the data set reflects geochemical differences, rather than analytical or data transfer errors. Next, we use bivariate plots, as well as PCA and CLR–PCA, to examine different versions of our altered data, using varying numbers of element combinations. We propose that the careful examination of bivariate plots is critical in establishing the elements that should be included in PCA and other multivariate analyses.  相似文献

ABSTRACT. The recent process of housing redevelopment in central Moscow is examined in the light of the theory of gentrification. The study is based on the case of Ostozhenka as an emblematic example of a large–scale transformation of a central residential neighbourhood into the most expensive quarter of central Moscow. Using data collected through interviews, archive enquiries and field surveys, the paper addresses the preconditions, dynamics and mechanisms of this socio–political process. It is argued that gentrification in Ostozhenka shares many features observed in the other large cities of the world but, as predicted by theory, is locally embedded. It has been a product of a complex interplay of the market pressure aiming to meet demands from Moscow's successful post–Soviet economy and Moscow government's entrepreneurial and pro–development strategy for the city centre regeneration. The government privileges market forces: it empowers them vis-à-vis the original population and allows them to circumvent conservation institutions, while the achieved profit is shared between the private and public sides. Whereas the physical improvement of the city centre signifies departing from the Soviet legacies of under–investments in the housing built environment, the growing socio–spatial polarization undermines the social achievements of the Soviet system and denotes the triumph of the neoliberal urban regime in Moscow.  相似文献

We test whether commonly used measures of agglomeration economies encourage new firm entry in both urban and rural markets. Using new firm location decisions in Iowa and North Carolina, we find that measured agglomeration economies increase the probability of new firm entry in both urban and rural areas. Firms are more likely to locate in markets with an existing cluster of firms in the same industry, with greater concentrations of upstream suppliers or downstream customers, and with a larger proportion of college‐educated workers in the local labor supply. Firms are less likely to enter markets with no incumbent firms in the sector or where production is concentrated in relatively few sectors. The same factors encourage both stand‐alone start‐ups and establishments built by multiplant firms. Commuting decisions exhibit the same pattern as new firm entry with workers commuting from low to high agglomeration markets. Because agglomeration economies are important for rural firm entry also, policies encouraging new firm entry should focus on relatively few job centers rather than encouraging new firm entry in every small town.  相似文献

ABSTRACT A recent theoretical literature tries to understand the migration pattern in developing economies through the lens of search‐matching (SM) models, but there has been little empirical support for these models. This paper tries to fill this gap by examining whether the models are consistent with the data from developing economies. Combined with some suggestive statistics, our calibration exercise reveals that when augmented with additional frictions (fixed costs of starting up new businesses and mobility costs), our SM model can account for the data and is at least more consistent with the data than traditional Harris–Todaro models.  相似文献

What is the problem that “epistemic virtues” seek to solve? This article argues that virtues, epistemic and otherwise, are the key characteristics of “scholarly personae,” that is, of ideal‐typical models of what it takes to be a scholar. Different scholarly personae are characterized by different constellations of virtues and skills or, more precisely, by different constellations of commitments to goods (epistemic, moral, political, and so forth), the pursuit of which requires the exercise of certain virtues and skills. Expanding Hayden White's notion of “historiographical styles” so as to encompass not only historians' writings, but also their nontextual “doings,” the article argues that different styles of “being a historian”—a meticulous archival researcher, an inspired feminist scholar, or an outstanding undergraduate teacher—can be analyzed productively in terms of virtues and skills. Finally, the article claims that virtues and skills, in turn, are rooted in desires, which are shaped by the examples of others as well as by promises of reward. This makes the scholarly persona not merely a useful concept for distinguishing among different types of historians, but also a critical tool for analyzing why certain models of “being a historian” gain in popularity, whereas others become “old‐fashioned.”  相似文献

ABSTRACT Whether urbanization economies stem from urban diversity or urban scale is not clear in the literature. This paper uses the 2004 China manufacturing census data and tests simultaneously the effects of urban size and industrial diversity on firm productivity, controlling for localization economies and human capital externalities. We find that productivity increases with city size—but at a diminishing rate, and the city size effect becomes negative for cities with population over two million. Firms also benefit from industrial diversity, and the strength of such benefit increases with city size but decreases with firm size. The characteristics of agglomeration economies in a transition economy are also discussed.  相似文献

Abstract

Blacksmith James Luck’s papers indicate a complex web of credit in Milford, a small Surrey village, in the mid-Victorian era. His family benefited from contacts secured through loans, with the wider rural economy clearly depending on payment for goods and services being stretched over a long period of time. Despite the rise of banks and a national communications system, local knowledge and trust continued to be of significance. Local traders and their customers relied heavily on credit so it was important that the great majority of their transactions were sound. The records of James Luck illuminate this under-appreciated but significant aspect of 19th-century British family and community history.  相似文献

Taking Chun‐chieh Huang's ruminations on the defining character of Chinese historical thinking as a starting point, this essay discusses the ways in which historical cultures and traditions are compared and contrasted and explores some new ways of thinking. It argues that cultural comparisons often constitute two‐way traffic (one begins to examine itself after encountering the other) and that attempts to characterize one historical culture, such as that of China, are often made relationally and temporally. When the Chinese tradition of historiography is perceived and presented in the West, it has been regarded more or less as a counterexample against which the “unique” traits of Western historical thinking are thrown into relief. Given the hegemonic influence of Western scholarship in modern times, latter‐day Chinese historians also valorize the East—West dichotomy. A closer look at this dichotomy, or the characterization of both cultures, reveals that it is not only relative but also relational and temporal. When the modern Chinese appeared impressed by the rigor of Rankean critical historiography, for example, they were essentially attempting to rediscover their own cultural past, for example, the eighteenth‐century tradition of evidential learning, in adapting to the changing world. Our task today, the essay contends, is to historicize the specific context within which cultural comparisons are made and to go beyond readily accepted characterizations in order to reassess certain elements in a given culture, to apply historical wisdom, and to cope with the challenges we now face.  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

Philip Gorski's edited book engages the question of how Bourdieu's concepts can aid historical analysis, and in particular, account for change as well as reproduction. From a fascinating set of papers, this review essay takes special notice of two that theorize crisis. One, by Ivan Ermakoff, engages the question of whether disruption creates the opportunity for more conscious calculation on the part of actors; a second, by Gisele Sapiro, considers how a crisis reverberates through a specific field. This leads to further reflection on Bourdieu's work on power and the state, as well as a call for crisis hermeneutics in social theory.  相似文献

The role of the European nobility and their ability to retain their political and economic power are part of the debate on the modernization of Europe’s economy. This paper contributes to the literature by exploring the wealth of the Swedish nobility as the country evolved from an agrarian to an industrial economy. We use a sample of 200+ probate inventories of nobles for each of the benchmark years 1750, 1800, 1850 and 1900. We show that the nobility, less than 0.5 per cent of the population, was markedly dominant in 1750: the average noble was 60 times richer than the average person, and the nobles held 29 per cent of all private wealth. 90 per cent of the nobles were richer than the average person. By 1900 the advantage of the nobles’ wealth had declined; the group held only 5 per cent of total private wealth. At the same time, stratification within the nobility had increased dramatically. One group of super-rich Swedish nobles, often large land owners from the high nobility, possessed the biggest fortunes, but a large minority of nobles were no richer than the average Swede.  相似文献

The term “post-truth” is a capacious trope that collects threats to the stability of shared knowledge on many fronts—digitally spread disinformation, ignorance and resistance to science, unabashed lies in the public sphere, mythologizing by resurgent nationalist forces, and so on. History is particularly vulnerable to this array. Post-truth threats to serious history produced to professional standards for research and reasoning by historians free of coercion, intimidation, or pressures for co-optation are too blatant to need explanation. Avenues of response to the politicizing of history have been protests by public intellectuals and academics and a growing scholarly literature recording the imposition of memory laws by the police powers of numerous states. Attacks on empirical history, and the academic freedom required to sustain it, provoke clear responses, but the situation of historical theory is more problematic. Historical theory is a superstructure of analysis that presupposes the free production of history that invites and justifies the cultural work of theorizing. Reading Karen S. Feldman's Arts of Connection: Poetry, History, Epochality, an erudite, philosophical contribution to historical theory advancing a severe critique of history's fundamental powers of representation against a widening background of nationalist state-sponsored policing of history, produced an acute cognitive dissonance in this reviewer. In this essay, I frankly acknowledge this dissonant experience and lay out some of the most egregious causes of it in history distorted and undermined to nationalist ends in Russia, Poland, Hungary, and beyond. I pose the question of whether the intellectual work of theorizing history can continue with any confidence when the ground on which theory stands is being eroded and distorted.  相似文献

THE ASSOCIATION BETWEEN URBAN SPRAWL AND OBESITY: IS IT A TWO‐WAY STREET?   总被引:1,自引:0,他引:1  
ABSTRACT.  We empirically examine the relationship between obesity and urban development patterns where individuals reside. Previous analyses treat urban form as exogenous to weight, and find higher body mass indices (BMI) among residents of areas with sprawl patterns of development. Using samples of recent movers, we find that the causality runs in both directions. Individuals who move to denser locations lose weight. As well, BMI is a determinant of the choice of a dense or sprawling location. In sum, while moving to a dense area results in weight loss, such locations are unlikely to be selected by individuals with high BMI.  相似文献

Richard Kirkendall's collection of essays, The Organization of American Historians and the Writing and Teaching of American History, examines the history of the Organization of American Historians (OAH) from its founding to the present, using that history to illuminate how the writing of American history has changed over the last hundred years. The book provides coverage of all the major dimensions of the Mississippi Valley Historical Association's (MVHA) and the OAH's activities, ranging from the work of its scholarly publications, the Mississippi Historical Valley Review and the Journal of American History, to its role in promoting the teaching of American history. Overall, the essays in the volume tell a story of the organization's progress toward greater inclusion and democracy, falling prey to a Whig interpretation of historiography. In doing so, the book is part of a larger tendency in the way that historians have approached historiography, which in turn reflects their ambivalence about their relationship to the historical process. Thus, even as the very enterprise of historiography is premised on the recognition of how historians are themselves the products of the historical process, historians have revealed the limits to that recognition in their approach to the subject. This essay shows how deeply rooted this duality has been in the study of American historiography and illuminates some of its sources by placing Kirkendall's book in the context of how the MVHA and the OAH have treated historiography over the course of the organization's history.  相似文献

The first part of this essay presents an outline of ‘1968’ in Norway focusing on national particularities, especially the lack of violence. Three elements are highlighted: the political left turn with the opposition to the Vietnam War and the strong Marxist‐Leninist faction as main aspects; the student revolt; and the multifarious countercultural movement. The theme of the second part is the state of Norwegian 1968 historiography. Here a distinction is drawn between actors‐cum‐historians and historians proper, or rather between writers with a desire to commemorate – predominantly but not exclusively former communists – and writers whose interest in the events is more professionally historiographic.  相似文献
