Oxygen Isotopes and Human Residential Mobility in Central Western Argentina

Stable oxygen isotopes (δ¹⁸O) from human bone apatite from central western Argentina (30º–37ºS latitude) were analysed to understand changes in human residential mobility during the Late Holocene. This region contains evidence for the use of domesticated plants over the last 2000 years (Zea mays, Cucurbita sp. and Phaseolus sp., among others), and previous models of prehistoric occupation have suggested a distinct change in mobility and population movement associated with their incorporation. The importance of these domesticates also seems to have varied geographically, being greater in the northern part of the region and declining as one moves south toward the limit with Patagonia. Expectations about patterns of residential mobility have varied accordingly. To better evaluate these models, we analysed carbonate δ¹⁸O from the bone apatite of 71 individuals with radiocarbon dates spanning the last 6000 years. Given the existing evidence, we expected to see temporal and geographic differences in their oxygen isotope values associated with changes in residential mobility and the incorporation of different sources of drinking water available within the region. These expectations were not met. Significant variations were seen across all samples compared, both temporal and geographic, with no discernible differences among them. The data suggest that populations throughout the area were all highly mobile, and that this did not change with the incorporation of domesticates. Copyright © 2011 John Wiley & Sons, Ltd.     

A place-based policy for promoting Industry 4.0: the case of the Castellon ceramic tile district

ABSTRACT

Digitization and its impact on regions and clusters remains overlooked in the literature, and constitute this present paper’s goal. How does an industrial district transit collectively to the adoption of new radical changes brought about by Industry 4.0? This study explores the role of collective actors and innovation platforms during the early stages of a pilot policy to stimulate a collective transition of an entire MID (Marshallian Industrial District) into Industry 4.0. We posit that institutional isomorphism and the existent social capital in MIDs is a double-sword phenomenon that can also positively constitute an enabler for fostering change on a collective-basis. Technology transitions, such as Industry 4.0, can be supported and led by collective actors that are central in facilitating the adoption of Industry 4.0 in MIDs, enticing innovative firms to engage in that transition, establishing, legitimizing, and embedding a new set of processes, practices and inter-firm arrangements for digitizing and then promoting imitation: the positive leverage of isomorphism. Thus, MID transition is facilitated through capitalizing on the MID logic of cooperation-competition and isomorphism, by developing and promoting a collective understanding of the new paradigm, building a supportive infrastructure, educating in the new technology and avoiding cognitive inertia.
