The twentieth century dynamics of United States regional invention trends are explored in this study. Historically, regions that become major loci of invention have always gained much influence, through innovation diffusion, their human capital infrastructures, and their national economic and political projection. The United States has experienced a remarkable inversion of regional roles on invention since the middle of the twentieth century, where the predominant position of heartland regions (the Northeast and the Midwest) is being overturned. This analysis develops a macro-level measure of inventive output, innovative capacity, to evaluate changes in regional inventive performance and the potential for innovation. The analysis of patent age cycles provides insights on the temporal structure of the national and regional innovative capacity, and on the dynamics of crisis periods for U.S. scientific and technological invention. A consideration of regional income trends over the twentieth century and of innovative capacity performance shows the potential importance of endogenously generated inventions for regional development. 相似文献

So far, the relationship between Industrial Districts (IDs; clusters of interconnected local industries) and migrant enclaves (areas with a high concentration of international migrants from a single nationality) has been studied mostly by focusing on the emergence of ‘ethnic enclave economies’ within the district and/or by highlighting racist conflicts that achieved notoriety in the media. In this study, we contend that there is a more general and complex interaction between the two phenomena. This interaction is mediated by the local context, national regulations, and the organization of the international market, among other factors. By focusing on the case of the ceramic ID of Castelló de la Plana (Spain), we show how this ID with a high rate of job formality, combined with other job opportunities and a unique ‘institutional completeness’, set up the conditions for a non-conflictive Romanian migrant enclave that reached 14% of the town’s total population in 2012. Finally, and also considering another case study of ID and migrant enclave (Prato, and its Chinese enclave), we suggest a model of interaction that should be interpreted taking into account the general dynamics of the international organization of value and the requirements of flexibility and reduction of costs that frame IDs. 相似文献

This paper analyses the implementation of the International Fund for Cultural Diversity (IFCD), emerged from the Convention on the Protection and Promotion of the Diversity of Cultural Expressions (UNESCO 2005). The uniqueness of this multilateral fund is that most of its resources are aimed at supporting actions of non-governmental organizations functioning within the fields of cultural policy and cultural industries in developing and underdeveloped countries. Through a thorough study of different decisions and documents, this text analyses the IFCD’s funding, the results of the first calls for initiatives and the support obtained by projects focused on the audiovisual industry. Conceived as an instrument to implement initiatives whose goal is to strengthen the cultural sphere of the poorest countries, the hitherto modest IFCD faces now questions about its future growth and effectiveness in terms of changing the existing imbalance at work within the flows of audiovisual content both regionally and internationally. 相似文献

This article presents three years of archaeological investigations at the minor Maya center of Bejucal, Guatemala. A complete site history is presented relying on data from artifact analysis, architectural study, epigraphy, and bioarchaeology, with a goal towards identifying the site's function within the broader El Zotz polity. The authors argue that Bejucal underwent significant transformation following its establishment as a sacred hilltop site during the Late Preclassic period (400 b.c.–a.d. 250). The El Zotz royal family gradually appropriated the space, converting it into a royal country house and elite burial place. Bejucal's proximity to a large permanent water source suggests that the country house was situated within favorable hunting grounds. The research contributes to a broader discussion about the role of minor centers in regional settlement patterns, highlighting the benefit of textual data in making interpretations. The article also highlights the important role of salvage work in lowland Maya archaeology. 相似文献

The anatomy of a new articulated enantiornithine bird skeleton from the Late Cretaceous of Patagonia clearly indicates a capacity for powered flight, approaching that of modern birds. Enantiornithines possess some of the synapomorphies of the Ornithurae, although they retain plesiomorphic states for many other characters, mainly in the hind limb. Such a mosaic character combination suggests a sister-group relationship between Enantiornithes and Ornithurae. Derived features of the pectoral girdle are here considered as diagnostic for a major avian clade, the Ornithopectae, comprising all known birds other than Archaeopteryx. The combination of derived and primitive traits in the fore and hind limbs and their girdles in early ornithopectines reflects mosaic evolution, with flight-related modifications of the fore limb and pectoral girdle preceding those in the hind limb and pelvic girdle. 相似文献
