Advancing the Analysis of Past Human/Plant Relationships: Methodological Improvements of Artefact Pollen Washes

The ‘pollen washes’ technique, based on the analysis of the pollen embedded in the porous surface of archaeological artefacts, is developed for investigating past plant usage and consumption and to characterize the functionality of artefacts related to plant processing, gathering and storage. The research presented results in relevant methodological improvements of this technique, which has never previously been applied on materials from European contexts. The improvements allow: (1) faster analysis of a broad series of artefacts or those with large use‐surface areas likely to retain more pollen; and (2) a more thorough, deeper and precise cleaning method, allowing the study of smoother artefacts. Finally, the recovery of Trifolium‐group pollen from a macro‐lithic tool from Xicotó rock shelter (Montsec ranges, Spain) demonstrates that the pollen washes technique can reveal new insights into both the use and consumption of wild and domestic plants by prehistoric societies, and the functionality of archaeological objects whose interpretation is still problematic.     

Bell Beakers in the Southern Meseta of the Iberian Peninsula: Socioeconomic Context and New Data

An updated summary of the Bell Beaker problem in the Southern Meseta of the Iberian Peninsula is presented, following the great increase of new finds resulting from the latest surveys and excavations. Totalling 181 sites, this is one of the biggest concentrations of Beaker sites in Europe. High-quality information, however, is still restricted to the one extensively excavated and recently published site, the settlement of El Ventorro (Madrid). The available information is compared with that of the Northern Meseta, and a model is presented of the role Beakers played, as a ritual drinking-set, in the development of ranked societies in the inner regions of Iberia.     

The Importance of Creative Industry Agglomerations in Explaining the Wealth of European Regions

This paper examines the existence of regional agglomerations of manufacturing, service and creative industries, the relationship between these industries and the wealth of regions and their industrial structure. Through an analysis of 250 European regions, three important conclusions can be inferred from the results obtained in this paper. The first is that creative industries play an important role in the wealth of a region. The second is that the most creative regions are characterized by having more high-tech manufacturing industries than the rest of the regions although the number of low-tech manufacturing firms is similar. Lastly, the industrial structure of each region has a greater influence on regional wealth than the existence of industrial agglomerations. The importance of this paper resides in the fact that up until now no analysis has demonstrated that creative industries are the most important industries in regional wealth.     

The Economic Geography of the Meso-global Spaces: Integrating Multinationals and Clusters at the Local–Global Level

The local–global phenomenon literature is fragmented between the fields of international business and economic geography (EG). In the case of the latter, the literature, produced within the global production networks (GPNs) and global value chain frameworks, does not address the central role of firms, especially multinationals which co-locate and connect territories along GPNs. This paper develops a cross-field conceptual integration in order to enrich the EG perspective, using qualitative research methodology to test the framework. The results have important implications for scholars and policymakers.     

The Transition to the Acheulean in East Africa: an Assessment of Paradigms and Evidence from Olduvai Gorge (Tanzania)

The origin of the Acheulean constitutes a key aspect of current research in the archaeology of human evolution. Olduvai Gorge is one of the main sites in Africa in the study of the transition from the Oldowan to the Acheulean, due to both the uniqueness of its archaeological record, and the influence of early investigations at Olduvai on the development of Early Stone Age research. This paper reviews the impact of work at Olduvai in shaping a modern view of cultural evolution from the Oldowan to the Acheulean. It also evaluates the lithic assemblages excavated by Mary Leakey in Olduvai Middle and Upper Bed II, based on a first-hand review of the collections. We conclude that previous paradigms used to explain inter-assemblage variability are not superseded as much as generally assumed, and that a modern view of the origins of the Acheulean requires a reassessment of the cultural, biological, and paleoecological evidence at Olduvai and elsewhere in Africa.

Orinoquia: The Archaeology of the Orinoco River Basin

Orinoquia is one of the most important riverine ecosystems complexes of the world. However, it has been seldom recognized as an ecological or historical entity in general accounts of South American archaeology. This essay reviews systematically and comparatively the archaeology of Orinoquia, by discussing research done from the 1940s onwards in all the areas of the Orinoco Basin: the Andes, the plains or llanos, the Orinoco river proper, the highlands of Guayana, and the Delta. It is proposed that, in the last 20 years, there has been a sustained movement away from a traditional archaeology, concerned mostly with environmental determinism and cultural history, to new and pluralistic models that share, in spite of their diversity, a regional, long-term, and multidisciplinary approach.     

English-Language Assistance Programs, English-Skill Acquisition, and the Academic Progress of High School Language Minority Students

Utilizing the 1988–1992 surveys from the Restricted-Use National Education Longitudinal Study of 1988, I find that language minority students who received English-language assistance (ELA) programs beyond the third grade reported lower English-skill acquisition and made smaller academic progress in high school than their peers. Moreover, while the type of high school ELA program (e.g., bilingual education) differently affected scholastic outcomes, students in such programs did not surpass their counterparts in monolingual-English classes on average.     

THE EVOLUTION OF U.S. CITY SIZE DISTRIBUTION FROM A LONG‐TERM PERSPECTIVE (1900–2000)*

ABSTRACT This paper analyses the evolution of city size distribution in the United States throughout the twentieth century. It tests the validity of two empirical regularities studied in urban economics: Zipf's law (the rank‐size rule), and Gibrat's law, or the law of proportionate growth. The main contribution of this work is the use of a new database with information on all the cities (understood as incorporated places), without size restrictions. Our results enable us to confirm that Gibrat's law holds (weakly), and that Zipf's law holds only if the sample is sufficiently restricted at the top, not for a larger sample.
