This article revisits Robert Markus's account of the de-secularization of the Latin West between Augustine and Gregory the Great. It uses letters of advice for rulers written by early sixth-century clerics to contest his narrative of a ‘grand simplification’ of Christian thought. Multiple overlapping conceptions of the secular were still in play after the fall of Rome, articulated, not in the absence of, but in dialogue with robust political institutions. By uncoupling Christian ideas of secularity from the actual degree of religious pluralism or tolerance in a given society, historians can better capture the continued complexity of early medieval secularities.  相似文献

Many factors governed the penetration efficacy of prehistoric projectile weaponry. Archaeologists broadly focus their efforts on understanding the effect of stone weapon tips because these specimens are often the only part of the weapon system that survives in the archaeological record. The tip cross-sectional area (TCSA) and perimeter (TCSP) of stone weapon tips have been shown to correlate with target penetration depth. Here, using results from both static and dynamic penetration testing, we compare TCSA and TCSP against other tip geometry metrics: lateral surface area (LSA) and volume (V). Our analyses broadly show that using a single-point geometry metric evaluated at multiple locations along the length of the point, or using multiple geometry metrics evaluated at a single location, better predicts required energy than using a single-point geometry metric evaluated at a single location. Our results also show that in the case where a single geometry metric evaluated at multiple locations is used LSA provided the most robust prediction models. Finally, our results show that for the case where all geometry metrics evaluated at a single location are used the location that provides the most robust prediction model is dependent on how far the point penetrated the target.  相似文献

Road safety research is a data-rich field with large social impacts. Like in medical research, the ambition is to build knowledge around risk factors that can save lives. Unlike medical research, road safety research generates empirical findings from messy observational datasets. Records of road crashes contain numerous intersecting categorical variables, dominating patterns that are complicated by confounding and, when conditioning on data to make inferences net of this, observed effects that are subject to uncertainty due to diminishing sample sizes. We demonstrate how visual data analysis approaches can inject rigor into exploratory analysis of such datasets. A framework is presented whereby graphics are used to expose, model and evaluate spatial patterns in observational data, as well as protect against false discovery. Evidence for the framework is presented through an applied data analysis of national crash patterns recorded in STATS19, the main source of road crash information in Great Britain. Our framework moves beyond typical depictions of exploratory data analysis and transfers to complex data analysis decision spaces characteristic of modern geographical analysis.  相似文献

The issue of fairness often is central within environmental policy debates. The recent proliferation of state and local comparative risk projects for informing the selection of environmental policy priorities offers an appropriate setting to explore the issue of procedural fairness in risk-based decisionmaking. This paper describes and evaluates the process by which one of the initial state comparative risk projects, Washington's “Environment 2010,” attempted to include a broader range of participants in identifying, assessing, and generating preferred management strategies for a wide range of environmental hazards. The Washington case study suggests that comparative risk projects can be fairer procedurally, but that significant barriers remain. Noting that greater procedural fairness does not necessarily produce greater substantive fairness, the paper concludes that more attention needs to be directed at the process by which comparative risk projects translate their consensus upon risk priorities into subsequent actions.  相似文献

Recent fieldwork has considerably increased our knowledge of early Holocene settlement in Southwest Arabia. Neolithic settlement occurred within an environmental context of increased monsoonal moisture that continued during the mid-Holocene. A now well-attested Bronze Age exemplified by village- and town-scale settlements occupied by sedentary farmers developed toward the end of the mid-Holocene moist interval. The high plateau of Yemen was an early focus for the development of Bronze Age complex society, the economy of which relied upon terraced rain-fed and runoff agriculture. On the fringes of the Arabian desert, the precursors of the Sabaean literate civilization have been traced back to between 3600 and 2800 B.P., and even earlier, so that a virtually continuous archaeological record can now be described for parts of Yemen. In contrast to the highlands these societies relied upon food production from large-scale irrigation systems dependent upon capricious wadi floods. Bronze Age settlement, while showing some links with the southern Levant, now shows equal or stronger linkages with the Horn of Africa across the Red Sea. Although some regions of Yemen show breaks in occupation, others show continuity into the Sabaean period when a series of major towns grew up in response to the incense trade with the north. It is now clear that these civilizations grew up on the foundations of earlier Bronze Age complex societies.  相似文献

This paper focuses on the identification of three sets of relationships exhibited by a time series of age-specific national migration rates and multiregional transition probability matrices: the relationship across time for the same age group, as defined by period (temporal) transformation coefficients or matrices; the relationships across age at a particular moment in time, as defined by age transformation coefficients or matrices; and the relationships across time and age, as defined by cohort transformation coefficients or matrices. Given any two of these relationships one can solve for the third. This feature of age-period-cohort relationships has a practical application in the development of improved methods for representing structural change in migration patterns over time and for indirectly estimating migration patterns using inadequate data.  相似文献

Denmark was one of several European nations which vied for West African trade between the seventeenth and nineteenth centuries. The Danes established more than thirty forts, trading lodges and plantations on the Gold Coast, and they played an important role in the development of African-European relations in the region. Traces of Danish outposts and the results of recent excavations at the Daccubie plantation are briefly surveyed. The available data illustrate the circumscribed nature of African-European interaction on the Gold Coast, providing insight into the context in which culture change occurred within African populations. The archaeological record of European expansion in Africa and elsewhere is used to illustrate the varying nature of European contact.
Résumé Le Danemark était l'une des nombreuses nations européennes qui rivalisaient pour le commerce avec l'Afrique occidentale entre le dix-septième et le dix-neuvième siècles. Les Danois établirent plus de trente forts, comptoirs commerciaux et plantations sur la Côte de l'Or, et jouèrent un rôle important dans le développement des relations afro-européennes dans la région. Des traces de postes coloniaux danois et les résultats d'excavations récentes à la plantation de Daccubie sont brièvement passés en revue. Les données existantes illustrent le caractère limité de l'interaction afro-européenne sur la Côte de l'Or, donnant des indications sur le contexte dans lequel un changement culturel se produisit parmi les populations africaines. Les témoignages archéologiques de l'expansion européenne en Afrique et ailleurs servent à illustrer la nature changeante du contact européen.

In the early months of 1946 Dr H.V. Evatt made a concerted effort to shape the newly formed Security Council as a security tribunal. He wanted the Security Council to be governed by the principles of the United Nations Charter, to adopt regular procedures, to have an investigatory function and to make determinations on the facts of each case, not on the basis of power politics. Evatt attempted to implement his policy during the Iranian crisis despite the opposition of all the great powers, including the United Kingdom. This episode reveals the commitment to liberal internationalism that marked Australian foreign policy during this period and demonstrates both the possibilities and limits of an ‘idealist’ foreign policy.  相似文献
