It has been widely acknowledged in debates about nationalism and ethnicity that identity categories used for classifying people along the lines of culture, race, and ethnicity help to enact, that is, bring into being, the collective identities they name. However, we know little about how categories acquire their performative powers. The contribution of this paper is twofold: first, it proposes a conceptual framework based on concepts and insights from science and technology studies for investigating the performative powers of statistical identity categories and possibly also other domains. Second, it demonstrates, through an empirical study of two examples from Estonian and Dutch official population statistics, that statistical identity categories enact more than the groups to which they refer. We argue that they also enact national identities and notions of national belonging of majoritarian groups in the host countries. Therefore, statistical identity categories can be used as analytical lenses to study nationalism and processes of nation‐building.  相似文献

Archaeological studies of plantations need to consider the scale of the historical circumstances which shape locally circumscribed Creole processes. These circumstances range from broad generalizations down to factors operating only at the local level of the individual estate. Recent excavations at Estate Lower Bethlehem, St. Croix, Virgin Islands, have recovered an artifact assemblage from a laborer village dating from the mid-eighteenth century to the first quarter of the nineteenth century, which was situated adjacent to a previously unrecorded cemetery and a large tamarind tree. This assemblage illustrates the importance of a multiscalar approach to Creolization in two ways: an analysis of the distribution of vessel forms of European pottery and “Afro-Cruzan” earthenwares; and the identification of fragments of lead-glazed slip-decorated redware pottery produced by Moravians.  相似文献

The spread of early farming in Europe is revisited using a sample of 3072 audited 14C calBC dates from 940 georeferenced early Neolithic sites. The surface expansion of early Neolithic has been reconstituted using the kriging technique of spatial interpolation. Centres of renewed expansion, of contact zones, and the main routes of expansion have been highlighted by means of a vector map, representing the gradient. The expansion of the agricultural system on the map, was not uniform and regular across Europe as a whole, but proceeded in leaps. With the scale of detection of the 500-year isochrones, several leaps are identifiable: at 8000 calBC crossing the Taurus barrier, 6700–6100 calBC crossing the southern Adriatic barrier, 6100–5600 calBC crossing the Central European agro-ecological barrier and 5000–4000 calBC expanding on the other, marginal zones. Using a vector map, 10 points of renewed expansion and nine contact zones, were detected. The whole does not correspond to a process of homogeneous diffusion, approximately steady, but a process marked by phases of geographical expansion and stasis.  相似文献

Systems thinking is regarded as a key competence in the field of education for sustainable development (ESD), because it helps students to understand the complexity and dynamics of natural, social and economic systems. In our research group, we developed a competence model that distinguishes four dimensions of systems thinking in ESD. Based on this model, we designed different university courses in biology and geography teacher education and measured their effects on student teachers’ systems thinking and the pedagogical content knowledge for teaching systems thinking with two different tests. Both variables could be effectively promoted depending on the course.  相似文献

The concept of cross-border regional innovation systems (CBRIS) surfaced in the literature on economic geography through discourses that highlighted the need for broadening innovation systems to cross-border contexts. Since these early discussions, the theoretical backgrounds of CBRIS have been elaborated through notions of geographical scale, proximity and related variety in a range of conceptual papers proposing CBRIS as a comprehensive framework for analysing regional cross-border integration. However, the empirical literature on CBRIS has failed to keep up with the advances in conceptualization. This paper discusses the reasons behind this mismatch, which means that the concept still rests upon and draws policy suggestions based on a thin evidence base. Directions for further research are pointed out by underlining the need for holistic empirical validation of the concept together with the need of understanding how suggested policy measures based on CBRIS reasoning have been implemented in border regions, and their effectiveness in promoting cross-border integration.  相似文献

This paper presents a land-use change analysis of five Central and Eastern European (CEE) countries. We utilize CORINE (Coordination of Information on the Environment) Land-Cover and Urban Audit data for two distinct time periods: 1990–2000 and 2000–2006 aggregated at urban, suburban and non-metropolitan geographies. The literature on post-socialist cities suggests that urbanization rates and patterns in the post-socialist period are quite variable and divergent, both “inter”nationally and “intra”-nationally, and we expect to find both spatial and temporal differences. We compare and contrast urbanization patterns at the national scale, using cities and their functional urban regions as the unit of comparative analysis. Our results show that unlike other eastern European countries, metropolitan areas in the former German Democratic Republic began sprawling (defined as a decline in urban density) in the 1990s. Similar changes only became visible in other CEE countries later during the 2000s. We also demonstrate that larger cities which were better connected to the political elite and more economically integrated with global investment patterns experienced more extensive urban sprawl than their smaller and mid-sized counterparts.  相似文献
