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

Was the crisis of historicism an exclusively German affair? Or was it a “narrowly academic crisis,” as is sometimes assumed? Answering both questions in the negative, this paper argues that crises of historicism affected not merely intellectual elites, but even working‐class people, not only in Germany, but also in the Netherlands. With an elaborated case study, the article shows that Dutch “neo‐Calvinist” Protestants from the 1930s onward experienced their own crisis of historicism. For a variety of reasons, this religious subgroup came to experience a collapse of its “historicist” worldview. Following recent German scholarship, the paper argues that this historicism was not a matter of Rankean historical methods, but of “historical identifications,” or modes of identity formation in which historical narratives played crucial roles. Based on this Dutch case study, then, the article develops two arguments. In a quantitative mode, it argues that more and different people suffered from the crisis of historicism than is usually assumed. In addition, it offers a qualitative argument: that the crisis was located especially among groups that derived their identity from “historical identifications.” Those who suffered most from the crisis of historicism were those who understood themselves as embedded in narratives that connected past, present, and future in such a way as to offer identity in historical terms.  相似文献

The aim of this paper is to identify the determinants of the geographical mobility of skilled individuals, such as inventors, across European regions. Among a large number of variables, we focus on the role of social proximity between inventors’ communities. We use a control function approach to address the endogenous nature of networks, and zero‐inflated negative binomial models to accommodate our estimations to the count nature of the dependent variable and the high number of zeros it contains. Our results highlight the importance of physical proximity, job opportunities, social networks, as well as other relational variables in mediating this phenomenon.  相似文献

Global history looms large in current historiography, yet its heuristic design and political functions remain ill‐reflected. My article seeks to uncover the historical origins of the assumption that the “world” has one common history and that it is feasible and desirable to write it. I analyze the epistemic infrastructure underlying this assumption and argue that global history as practiced today is predicated on a specific mode of world‐making that provides its basic template: Global history both grew out of and intellectually sustains the conception of an increasingly connected world. The type of connectedness thereby implied and reinscribed was established by what I call the “world‐historical process,” a cognitive framework that co‐emerged with the early modern and modern European conquest of the world through expansion, discovery, commerce, and culture. The article investigates how this process‐template emerged out of the crisis of universal history that could no longer integrate and reconcile the multiple pasts of the world. The format of the world‐historical process was central to Enlightenment historians' assertion of the secular and scientific prestige of their craft, as much as to its ability to discern global epochs, in particular the modern and the premodern. My article traces the fortunes of this template through historicism up to present‐day global history. Current global history remains structured around the growing connectedness of previously distinct parts of the planet whose pasts are transformed into relevant world history by the very process that makes them increasingly interrelated. Global history may be too much a product of the process of globalization it studies to develop epistemologically and politically tenable alternatives to “connectivity.”  相似文献

Summary. Part I discusses the problem of the introduction of the claw chisel in stone masonry and sculpture. This tool was thought to have been invented in 6th-century Greece for the needs of marble carving. The detection of its traces on a tomb of 7th-century Egypt in soft limestone, however, now suggests not only that the Greeks borrowed it from the Egyptians but also that it was not originally a marbleworker's tool. Part II deals with both the tomb and career of an Egyptian official designated Nespeqashuty D in order to place into a chronological framework one of the earliest securely dated attestations for the use of the claw chisel in Egyptian art. Both parts are intended to place the impact of Egypt on Greece into sharper focus.  相似文献

Over the past four years, taxes levied by states on energy production have become a source of contention between the “energy have” and “energy have–not” regions of the nation. The popular notion that the taxes are shifted forward to consumers has gone virtually unchallenged in the policy debate. This paper examines the incidence and burden of severance taxes and also assesses the impact of severance taxation on production, investment, and land use. The author concludes that severance taxes are not shifted forward to consumers but are borne by producers and resources owners in the form of reduced profits and rents.  相似文献

In JAC16, I have discussed the development of the House of the Lady in Girsu from the rule of Enentarzi to Lugalanda according to the ration lists of the House,which include the fodder lists, and concluded that Urukagina was the legal successor of Lugalanda and there might not be the so-called “reforms of Urukagina” in Lagash and Girsu. In this article, I would like to continue to investigate the kinds, number and fodders of the donkeys from the rule of Enentarzi to the end years of Urukagina and tried to find the clues for the decline of Lagash under Uruka~ina.  相似文献

This article discusses the impact of genomic history, a subdiscipline that emerged in the study of the ancient Mediterranean in the 2010s. In 2014, scientists first published a method for extracting genetic material, which they christened aDNA (ancient DNA), from ancient human remains in hot climates. After a decade of research, genomic history is now poised to transform our understanding of Mediterranean premodernity, centering migration and conflict as the key mechanisms for cultural change. Despite years of critique, aDNA researchers have failed to seriously examine the bioessentialist assumptions implicit in their work—a failure that has led many to deploy language that is strikingly evocative of pre-World War II racialism. Even worse, some genomic historians continue to make troubling overtures toward the ethnonationalist Right, which has been ascendant across Europe and North America since the 2010s. This article traces the intellectual genealogy of genomic history from World War II to the present, examines recent attempts to answer criticism from the humanities and social sciences, and suggests paths for responsible use of aDNA in historical and prehistorical scholarship.  相似文献

Casa Montero is a mining complex located outside Madrid (Spain), dated from the Early Neolithic (c. 5400–5000 cal bc ). An area of some 4 ha has been investigated and some 4000 shafts recorded, of which 324 have been excavated. The characterization of its raw flint materials and the establishment of its diagnostic features are indispensable in the reconstruction of the distribution of the mine's products beyond the immediate site. This work reports the geological study of the mine's Miocene flint layers and their petrological characterization. Archaeological samples from the mine's shafts were classified according to macroscopic features and petrological characteristics.  相似文献
