Traditional studies of royal itinerancy have depended on locating the king’s progress through his kingdom(s) as precisely as possible and it should therefore not surprise that the iter regis in pre-conquest England has received relatively little attention, since Anglo-Saxon diplomas only rarely record their date and place of issue, making the establishment of the royal itinerary all but impossible. However, more recent studies, particularly by German scholars, have moved away from the earlier attention to the concrete details of the royal iter and focus more on the effects of itinerancy as a method of rulership, viewing itinerancy as a central part of royal ritual. This study argues that if we investigate itinerancy in tenth-century England from this standpoint, we can throw new light onto the subject. Contemporary sources reveal that in England as in France and Germany the iter regis was of great importance, with symbolic acts of feasting and gift-giving accompanying royal visits. The attention given to these ritualised acts in contemporary sources suggests, moreover, that Anglo-Saxon kingship possessed an important ‘charismatic’ quality, which deserves further investigation.  相似文献

The study of technology transfer in pottery production to the periphery of the Mycenaean world has been addressed by considering two different areas, southern Italy and central Macedonia. Technological features such as ceramic paste, decoration and firing have been determined for different ceramic groups established according to provenance criteria. The studies of technology and provenance have been performed following an archaeometric approach, using neutron activation analysis, petrographic analysis, X‐ray diffraction and scanning electron microscopy. The results have revealed the existence of two different models. On the one hand, southern Italy seems to exhibit a more organized pottery production, which follows a Mycenaean‐like technology, while in central Macedonia production is probably more varied, being based in part on the technology of the local tradition.  相似文献

Spatial econometric specifications pose unique computational challenges to Bayesian analysis, making it difficult to estimate models efficiently. In the literature, the main focus has been on extending Bayesian analysis to increasingly complex spatial models. The stochastic efficiency of commonly used Markov Chain Monte Carlo (MCMC) samplers has received less attention by comparison. Specifically, Bayesian methods to analyze effective sample size and samplers that provide large effective size have not been thoroughly considered in the literature. Thus, we compare three MCMC techniques: the familiar Metropolis‐within‐Gibbs sampling, Slice‐within‐Gibbs sampling, and Hamiltonian Monte Carlo. The latter two methods, while common in other domains, are not as widely encountered in Bayesian spatial econometrics. We assess these methods across four different scenarios in which we estimate the spatial autoregressive parameter in a mixed regressive, spatial autoregressive specification (or, spatial lag model). We find that off‐the‐shelf implementations of the newer high‐yield simulation techniques require significant adaptation to be viable. We further find that the effective sizes are often significantly smaller than nominal sizes. In addition, we find that stopping simulation early may understate posterior credible interval widths when effective sample size is small. More broadly, we suggest that sample information and stopping rules deserve more attention in both applied and basic Bayesian spatial econometric research.  相似文献

Single and Multiscale Models of Process Spatial Heterogeneity   总被引:3,自引:0,他引:3       下载免费PDF全文
Recent work in local spatial modeling has affirmed and broadened interest in multivariate local spatial analysis. Two broad approaches have emerged: Geographically Weighted Regression (GWR) which follows a frequentist perspective and Bayesian Spatially Varying Coefficients models. Although several comparisons between the two approaches exist, recent developments, particularly in GWR, mean that these are incomplete and missing some important axes of comparison. Consequently, there is a need for a more thorough comparison of the two families of local estimators, including recent developments in multiscale variants and their relative performance under controlled conditions. We find that while both types of local models generally perform similarly on a series of criteria, some interesting and important differences exist.  相似文献

In the famous chapters on the flaws of the Qin (221–207 BCE) dynasty, Jia Yi (200–168 BCE) deals with the reasons for the Qin’s defeat. This article, grounded in previous scholarship, will analyze Jia Yi’s discussion of the fall of the Qin and will show that the negative depiction of Qin policies was part of Jia Yi’s strategy for implementing the political agenda of the Han. Moreover I argue that the Guo Qin lun, or “To Surpass the Qin,” is not simply a historical analysis, but a political treatise that also deals with: (1) heeding the advice of meritorious ministers; (2) persuading the emperor to apply policies to bring tranquility to the people.  相似文献

The analysis of the skeletal remains of Ohalo II man, aged 30–40 years at death and dated to 19 000 years BP, shows advanced and highly unusual ossification of the lower costosternal cartilage; the right humerus is morphologically larger and considerably more robust than the left; degenerative changes were noted unilaterally in the right glenohumeral, acromioclavicular and claviculosternal joints. There is a marked asymmetry of the atlas, axis and occipital condyles. The changes in the costochondral area of the lower anterior rib cage are considered to represent an infectious chronic osteomyelitic process. The marked discrepancy in size between the left and right shoulder girdles and humeri, and the evidence of degenerative disease exclusively on one side only may be the result of a traumatic brachial plexus nerve palsy. The asymmetrical atlas and axis are most probably anatomical variants that do not reflect clinical pathology.  相似文献

Intermediate and Middle Bronze Age tombs with weapons (mainly daggers) in the southern Levant were often interpreted as ‘warrior graves’. Taking into consideration new data from Rishon Le‐Zion (Israel), recent work on early warfare and warriors, and a study of so‐called ‘warrior graves’ in Mesopotamia (Rehm 2003), we suggest that most of these graves are not graves of elite warriors, but typical male burials. We also discuss the assumed ‘burial kit’ and the decline in numbers of weapons per burial, which is in our view related to the shift from individual burials (in the Intermediate Bronze and Middle Bronze IIA periods) to multiple shaft burials (in the Middle Bronze IIB period).  相似文献

The Middle Bronze Age II is a period during which there exists a contemporaneous usage of arsenic copper and tin bronze for metal weaponry production. In order to learn more about the alloys used in this period, the blades and rivets from 65 daggers of two significantly different types, which were discovered at the Rishon LeZion (RL) cemetery, Israel, were tested by the non‐destructive method of X‐ray fluorescence (XRF). The results reveal new knowledge of the alloys selected for dagger and rivet production, both of which represent fine examples of the Middle Bronze Age II Southern Levant in metal industry.  相似文献
