The paper explores the connection between computerised techniques of mapping and the role of maps in modern nationhood, interrogating the ways that maps are naturalised and deployed in postcolonial neoliberal statecraft. A case study of Ecuador demonstrates how the relationship between cartography and the nation-state is being both altered and reaffirmed by new mapping practices and institutional processes. Despite neoliberalising moves to decentre state cartographers and the technological advances supporting the proliferation of national maps and map-makers, Ecuadorian cartographies are still authorised by the nation-state, as explored in relation to spatial information about the country, and in relation to the processes of land-titling. Under neoliberal governance and with advanced mapping techniques, land-titling produces small territories that replicate – in miniature – the jigsaw-like and modular quality of national territories. As such, mappings of individual private properties produce the reality of neoliberal statecraft. 相似文献

A multidisciplinary approach combining scientific and historical data is developed in order to identify the environmental factors that cause degradation of stones and to attempt to date the onset of degradation and assess the time needed for its development. The method is applied to the Castle of Chambord, a prestigious monument in the Loire Valley in France. The genesis of the two main types of degradation (spalling and flaking) and the kinetics of their development are identified and analysed. The correlation between the different mappings and iconographic documents reveal that flaking develops on any type of fine limestone and can appear less than 60 years after the stone is placed on the castle for Richemont limestone, and less than 10 years for tuffeau. The other main type of degradation, spalling, is limited to tuffeau, but it is more difficult to quantify the kinetics of its development. 相似文献

This is a paper about Alice Ravenhill, an under-scrutinized early twentieth-century colonial settler in British Columbia, Canada. It is also a paper about the relationship and deep connections that I developed with her through archival research, a relationship and set of connections that I suggest open new spaces to (re)consider present-day colonial power in British Columbia. Specifically, I propose that ‘against the grain’ archival readings of BC’s past, with an emphasis on finding evidence of resistance to colonial power, can serve to distance the present from the past, thus positioning both contemporary geographies and researchers at work in the province today as existing in a different time and place than those of Alice Ravenhill and other colonial subjects. If, by reading ‘along the archival grain’ as I attempt to do in this paper, we (particularly those of us who live and work in BC today) instead understand ourselves as deeply and emotionally connected to colonial settlers like Alice Ravenhill, and if we understand their lives and work as similar to our own, there is a chance we might avoid some of their more egregious undertakings. 相似文献

In 2011, Myanmar started its political transition after decades of military rule. In Kachin State this coincided with the breaking of a 17‐year ceasefire between the Kachin Independence Organization/Army (KIO/A) and the state army, the Tatmadaw. For youth living in Kachin State, this meant that opportunities for civic and political participation opened up while at the same time their context remained volatile and uncertain. Using citizenship theory and the concept of the ‘everyday’, this article analyses how youth in Kachin State connect the challenges they experience to their sense of citizenship, and how this informs everyday forms of youth action as well as youth participation in policy processes. The article argues that young people act out of moral and political reasons to ‘build Kachin’, in response to deeply historically rooted experiences of discrimination and state repression. While the agency of young people living in conflict settings is often believed to be limited to tactical agency for individual and immediate survival, an analysis of youth's experiences of citizenship shows that they also act strategically to advance the interests of their society. 相似文献

Charter schools have generated support from politicians in both major American political parties while stimulating intense debate among interest groups. We investigate whether and how public attitudes reflect interest group polarization or politician consensus. Using an original survey, we find that charter school opinions diverge along ideological lines among high‐information respondents. With embedded experiments, we manipulate respondents' information using policy cues tied to opposing sides of the charter debate: We assess whether the role of private companies and nonunion teachers changes support for charter schools. We find that the public responds favorably to some informational cues; conservatives without prior information are especially persuaded by information about nonunion teachers. This explains how polarized opinion can develop even in the absence of strong partisan sorting among top political leaders and clarifies the partisan and ideological context of ongoing education policy debates. 相似文献

Primary data, though an essential resource for supporting authoritative archaeological narratives, rarely enters the public
record. Lack of primary data publication is also a major obstacle to cultural heritage preservation and the goals of cultural
resource management (CRM). Moreover, access to primary data is key to contesting claims about the past and to the formulation
of credible alternative interpretations. In response to these concerns, experimental systems have implemented a variety of
strategies to support online publication of primary data. Online data dissemination can be a powerful tool to meet the needs
of CRM professionals, establish better communication and collaborative ties with colleagues in academic settings, and encourage
public engagement with the documented record of the past. This paper introduces the ArchaeoML standard and its implementation
in the Open Context system. As will be discussed, the integration and online dissemination of primary data offer great opportunities
for making archaeological knowledge creation more participatory and transparent. However, different strategies in this area
involve important trade-offs, and all face complex conceptual, ethical, legal, and professional challenges. 相似文献
