I look at the process and speed of innovation spread, examining the economic aspects from the perspective of those who adopt the innovation. Defining innovation adoption as an investment which requires initial cost and risks, I argue that at the time of introduction of a new technology that is expected to have socioeconomic importance, elites of adopting societies try to avoid the initial cost and risks of adoption, actively intervening in the process of its spread. Thus, it is crucial to analyze the strategies and needs of elites, which strongly influence the speed of spread. One of these strategies is to change innovation's role by locating the innovation in a different realm of economy. Comparing the spread of iron technology in the Danish and southern Korean Bronze Ages, I demonstrate that differences in what elites needed to obtain through iron technology in different contexts critically affected the speed and process of iron spread into the two regions. 相似文献
This study of Middle Palaeolithic assemblages from the Rhone Valley, in the South-East of France, increases our understanding of Neanderthal subsistence strategies and modes of territorial organisation by comparing a wide corpus of human occupations in limited chronological and geographical frameworks. The Neanderthal occupation modes may be examined using sites located in a reduced area, linking medium-altitude territories (Massif Central and the Alpine foothills) to the Rhone corridor. Through the combined analysis of the occupation levels of ten sites, all dated to between Marine Isotopic Stage (MIS) 7 and the beginning of MIS 3, we identify three types of occupation durations: (1) type 1 as long-term residential camps, (2) type 2 as short-term regular hunting camps and (3) type 3 as brief stopover camps. We discuss this variability of habitat types according to various parameters: site age, technical behaviour, environmental conditions, and site localisation and occupation seasons. The aim is to discern the underlying motivations behind Neanderthal group mobility. One of the main features of the Rhone Valley area is the great homogeneity of behaviours reflected within the sequences. This homogeneity, linked to the variability of the site occupations, supports the hypothesis of Neanderthal groups anticipating their land use requirements, and furthermore suggests that another type of circulating model was used in this area. 相似文献
Neighborhood is seen as one of the many social contexts that shape children's cognitive, emotional and social development. However, the neighborhood context does not simply ‘imprint’ itself on children, but can be mediated or moderated by other social contexts, in particular the family context through parenting practices. Based on a case study in a low income neighborhood in The Hague, The Netherlands, this paper addresses the question of how living in a disadvantaged neighborhood context constitutes a risk for children and which strategies parents develop in response to the perceived negative neighborhood influences. 相似文献
The consumption of small prey dates back to the Plio-Pleistocene chronologies in some African sites. However, the systematic acquisition and consumption of small prey in the pre-Upper Palaeolithic times is still a highly debated topic in Europe. Although the utilization of leporids has been recorded in several pre-Late Pleistocene European sites, the evidence of bird consumption is not as common for these periods. Nevertheless, Level XI (MIS 6) of Bolomor Cave has clear diagnostic elements to document the acquisition and use of birds (Aythya sp.) for food in the form of: (1) cutmarks on bones of both the front and hind limb; (2) presence of burning patterns on the extremities of the bones (areas of the skeleton with less meat); and (3) human toothmarks on limb bones. The capture of birds is classified as quick-flying game in the archaeological sites. The acquiring of fast-running (mostly lagomorphs) and quick-flying small prey requires a sophisticated technology and involves obtaining and processing ways different from those used for large- and medium-sized animals. From this perspective, the aim of this paper is to examine possible patterns in the processing sequence of birds from Level XI of Bolomor Cave and to improve the data on their butchery and human consumption in the Middle Pleistocene of Iberian Peninsula. 相似文献
The emergence of neurology as a separate specialty from internal medicine and psychiatry took several decades, starting at the end of the nineteenth century. This can be adequately reconstructed by focusing on the establishment of specialized journals, societies, university chairs, the invention and application of specific instruments, medical practices, and certainly also the publication of pivotal textbooks in the field. Particularly around 1900, the German-speaking countries played an integral role in this process. In this article, one aspect is extensively explored, notably the publication (in the twentieth century) of three comprehensive and influential multivolume and multiauthor handbooks entirely devoted to neurology. All available volumes of Max Lewandowsky's Handbuch der Neurologie (1910–1914) and the Handbuch der Neurologie (1935–1937) of Oswald Bumke and Otfrid Foerster were analyzed. The handbooks were then compared with Pierre Vinken's and George Bruyn's Handbook of Clinical Neurology (1968–2002).
Over the span of nearly a century these publications became ever more comprehensive and developed into a global, encompassing project as is reflected in the increasing number of foreign authors. Whereas the first two handbooks were published mainly in German, “Vinken & Bruyn” was eventually published entirely in English, indicating the general changes in the scientific language of neurology after World War II. Distinctions include the uniformity of the series, manner of editorial involvement, thematic comprehensiveness, inclusion of volume editors in “Vinken & Bruyn,” and the provision of index volumes. The increasing use of authorities in various neurological subspecialties is an important factor by which these handbooks contrast with many compact neurological textbooks that were available at the time.
For historiographical purposes, the three neurological handbooks considered here were important sources for the general study of the history of medicine and science and the history of neurology in particular. Moreover, they served as important catalyzers of the emergence of neurology as a new clinical specialty during the first decades of the twentieth century. 相似文献
The 1992–1993 civil wars in Moldova and in Georgia ended with a de facto separation of Transnistria and Abkhazia, respectively. These de facto states are both inhabited by the kin to the ‘enemy’ across the administrative border: Moldovans and Georgians/Mingrelians. How do the de facto authorities foster a collective identity in support of their claim for legitimacy and statehood? Engaging with Wimmer's taxonomy of boundary‐making, this article argues that nation‐building involves not only expansion but also, simultaneously, contraction. Transnistria constructs a higher‐level identity category and co‐opts and contracts the Moldovan category, separating it into ‘our’ and Bessarabian Moldovans in order to incorporate the former into the Transnistrian people. In Abkhazia, the nation‐building project establishes the Abkhazs as the titular nation allowing, however, for the construction of an Abkhazian people that would include minorities, with Gal/i Georgians said to be Mingrelians, distinct from Georgians. These cases show that elites combine different ethnic boundary‐making strategies in order to implement their favoured identity project and to legitimize the claimed statehood. 相似文献
ABSTRACTIn order to stimulate growth and competitiveness, many EU member states have implemented cluster-based development strategies. Several works underline the benefits of policy-driven clusters, but understanding how clusters can create value for their members is still an open issue. This work contributes to the literature by investigating 13 Competitiveness Clusters in Croatia, a special type of policy-driven clusters developed within the country’s smart specialization strategy, using original data from a survey on 250 cluster members. Our results indicate the existence of very different attitudes towards the rationale for the initiative. In particular, while some members are more interested in lobbying activities, others see networking and innovation as the most important objectives of clusters. Findings also show that the evaluation of cluster management, governance and performance varies according to the desired objectives. Overall the Competitiveness Clusters initiative in Croatia did not meet members’ expectations. 相似文献
