Archaeologists use a method of evaluating the characteristics of flakes, called scoring, to distinguish geofacts (pseudo-artefacts or eoliths) from artefacts. Lower total scores are considered indicative of a natural source of the finds, while higher ones support the opposite. However, this method has some limitations. The most important are the small quantity of assemblages subject to such an analysis and the unclear boundary drawn by a ranking within a point-based score evaluation between collections with finds of cultural and anthropic origin. Here, we present a method that minimizes these limitations. It consists of a statistical approach using scoring percentages, a new method of visualizing them and the application of clustering. This way, we obtained clear differences between pseudo-artefacts and artefacts by considering flakes from six flint assemblages from Central Europe as well as an experimental assemblage.  相似文献

The Eusebius Gallicanus sermons reveal the congruity in late antique Gaul between the models of pastoral care for monks and lay Christians. For these Gallic clergy, there was little antagonism between monastery and world. Preachers to both audiences share a common central concern with the defence of community and in this respect they differ from some of their contemporaries. The sermon collection demonstrates that the ascetic world in Gaul was far from monolithic and that pastoral care could be highly individualised and responsive to the demands of local communities.  相似文献

It is sometimes claimed that compulsory voting violates a particular right not to vote. For some, this assumed right is as fundamental as the right to vote. The existence of such a right, however, has attracted little sustained scholarly attention. This article explores from a political theory perspective whether the alleged ‘right not to vote’ is deserving the same legal and moral protection as the right to vote. I argue on two broad grounds that it is not. First, not all rights are capable of being legally waived and voting is one of them. Second, voting is a right but it is also a duty; it is a duty-right. Therefore, even though many people do fail to vote, doing so does not seem to constitute the exercise of any particular right, nor should it be legally recognised as such.

有人认为强制性投票侵犯了不投票的权利。对于很多人来说,不投票的权利跟投票的权利同等重要。不过这种权利却未得到学术界的持续关注。本文从政治学的角度探讨了所谓的“不投票权”是否应像投票权一样享有法律上和道德上的保护。笔者基于更宽泛的理由认为不应当。首先,并非所有权利都是可以在法律上免除的,投票权即是。其次,投票是权利,也是义务;是权利—义务。所以,尽管许多人没有投票,但这并不构成某种权利,法律上也不应被视作权利。  相似文献

When adequate data on migration are unavailable, demographers infer such data indirectly, usually by turning to residual methods of estimating net migration. This paper sets out and illustrates an inferential method that uses population totals in the first age group of birthplace‐specific counts of residents in each region of a multiregional system to indirectly infer the entire age schedule of directional age‐specific migration flows. Specifically, it uses an estimate of infant migration that is afforded by a count of infants enumerated in a region other than their region of birth to infer all other age‐specific migration flows. Since infants migrate with their parents, the migration propensities of both are correlated, and the general stability of the age profiles of migration schedules then allows the association to be extended to all other age groups.  相似文献

Complicating top‐down analyses of neoliberal development, this article charts how demographically diverse residents in Columbia Heights—a rapidly gentrifying neighborhood in Washington, DC—reinforce and resist dominant narratives of diversity that praise multicultural, mixed urban spaces. These narratives often not only fail to discuss power and equity, they are typically used to market state‐sponsored, upscale development that actively threatens the very diversity appropriated to sell a neighborhood. I argue that many residents initially reproduce this rhetoric of diversity, but discuss power and difference more candidly in their discussion of the neighborhood's history and amenities. Most residents who recently moved to the neighborhood juxtapose praise of diversity with comments that associate crime, litter, and “grime” with that diversity. Residents who grew up in Columbia Heights moved from praising the influx of development and new (largely upper‐middle class) residents to expressing concerns about exclusion, disrespect, and possible displacement.  相似文献

Time Lines, Folded Time, and Discourse Analysis: Continuities of Maternal Imagination. Focusing on a discourse‐oriented history of knowledge, this article deals with the relation between continuity and time. It will discuss concepts of linear and homogenous time and problematize a one‐sided focus on discontinuity and rupture in discourse analyses. After examining notions of continuity, discontinuity, and temporality in the work of Michel Foucault, I will ask how continuous elements can be theorized both as instruments and objects of research, without adopting a linear concept of time. Thus, Michel Serres' concept of folded time will be presented, because it implies a multiple, heterogenous and non‐linear temporality and entails both continuous and discontinuous entities. Thereby relations of power should be considered as factors influencing the shape of the folding. In this way, folded time can serve as a useful tool for discourse analysis, enabling to examine specific and local continuities that vary in different discursive formations. To give an example, I will briefly turn to the concept of women's imagination in pregnancy. According to most historical analyses, this concept declined in the middle of the 18th century and persisted afterwards only as an outdated remainder in folk knowledge. Nevertheless, a closer examination reveals that knowledge on imagination was actively produced in medical advice literature and some scientific discourses until the first decades of the 20th century. This demonstrates that an overemphasis both on rupture and on the timeline of academic medicine might conceal continuous elements and the folded time of specific knowledge formations.  相似文献
