Four Scottish indulgences at Sens

English interest in the great Cistercian abbey of Pontigny was stimulated by the exiles there of two archbishops of Canterbury, Thomas Becket and Stephen Langton.1 As archbishops of Canterbury, Langton and Edmund of Abingdon made gifts to Pontigny abbey in consideration of the welcome given to Becket.2 Edmund did not die at Pontigny, but was a confrater of the community, and the abbot claimed the body, asserting that Edmund had expressed a wish to be buried there. The process of canonisation was rapid.3 After Edmund's canonisation, Henry III sent a chasuble and a chalice for the first celebration of the feast, and granted money to maintain four candles round the saint's shrine.4 In 1254, en route from Gascony to meet Louis IX in Chartres and Paris,5 Henry visited Pontigny, as his brother Richard of Cornwall, who seems to have pressed for canonisation, had done in 1247.6 Archbishop Boniface of Canterbury ordered the celebration of the feast to be observed throughout his province.7 Pope Alexander IV granted a dispensation to allow Englishwomen to enter the precinct of Pontigny abbey on the feast of the translation of the relics of St Edmund8 (women were normally forbidden to enter a Cistercian monastery). Matthew Paris, the greatest English chronicler of the age, wrote a life of the saint.9 English interest continued into the fourteenth century. In 1331 an English priest was given a licence to visit the shrine,10 but it seems likely that the Hundred Years’ War made pilgrimage to Pontigny difficult.11 The indulgences preserved by the abbey reveal an interest in the shrine throughout the Western Church, granted as they were by prelates from Tortosa to Livonia and Estonia, and from Messina to Lübeck.1

Service quality measurements for IPv6 inter-networks

Measurement-based performance evaluation of network traffic is becoming very important, especially for networks trying to provide differentiated levels of service quality to the different application flows. The non-identical response of flows to the different types of network-imposed performance degradation raises the need for ubiquitous measurement mechanisms, able to measure numerous performance properties, and being equally applicable to different applications and transports. This paper presents a new measurement mechanism, facilitated by the steady introduction of IPv6 in network nodes and hosts, which exploits native features of the protocol to provide support for performance measurements at the network (IP) layer. IPv6 Extension Headers have been used to carry the triggers involving the measurement activity and the measurement data in-line with the payload data itself, providing a high level of probability that the behaviour of the real user traffic flows is observed. End-to-end one-way delay, jitter, loss, and throughput have been measured for applications operating on top of both reliable and unreliable transports, over different-capacity IPv6 network configurations. We conclude that this technique could form the basis for future Internet measurements that can be dynamically deployed where and when required in a multi-service IP environment

The Components of a Competency Based Elementary Reading Program

In a competency based reading program, the instructional emphasis is on each student\u27s successful attainment and completion of the specific learning objectives provided. As such, the length of time required for each individual student to complete the objectives may be different

Epiplastral and geographic variation in Echmatemys, a geoemydid turtle from the Eocene of North America: A multi-tiered analysis of epiplastral shape complexity

Numerous geoemydid turtle fossils from the extinct genus Echmatemys have been recovered from the middle Eocene Uinta Formation, Uinta Basin, Utah over the past several decades. Here, we tested whether co-occurring Uintan species Echmatemys callopyge and E. uintensis can be reliably differentiated based on epiplastral morphology, and whether their geospatial distributions overlapped significantly. The geographic spatial and stratigraphic distributions of Uinta Basin E. callopyge and E. uintensis specimens were compared using ArcGIS and analysis of variance (ANOVA). The analysis revealed overlapping geographic distributions of these two species, and no significant differences in stratigraphic dispersal. This finding of extensive geospatial overlap between the two Uintan Echmatemys species highlights the need for accurate taxonomic identification, such as the gular scale morphology validated here. In addition, we sought to address a methodological question regarding the relative efficacy of data complexity in this context. Using epiplastra from three additional Eocene species of Echmatemys, we employed hierarchical analyses of increasing data complexity, from standard linear dimensions to 2D geometric morphometrics to 3D laser scans, to determine the degree to which data complexity contributes to taxonomic assessments within this genus. Uintan species E. callopyge and E. uintensis were found to differ significantly in epiplastral shape as captured by all three categories of data. These findings verify that these two co-occurring species can be differentiated consistently using the shape of the gular scale, and that the use of geometric morphometrics can improve identification of fragmentary specimens. Among the non-Uintan species, dorsal and ventral 2D landmark data reliably differentiated among species, but the linear dimensions were less useful

The Fate of Arsenic in Noah’s Flood

One potential consequence of Noah’s Flood would be the mobilization of toxic elements such as arsenic (As), a group 15 metalloid with a significant solubility and redox chemistry in water and a high toxicity to human beings. This paper discusses the likely chemistry of arsenic during the Flood. The Flood would have released arsenic through hydrothermal activity, volcanic eruptions, and weathering of crustal rock. Arsenic in hydrothermal fluid would likely be rapidly precipitated by sulfides. Likewise, much of the arsenic in volcanoes would actually be deposited sub-surface as sulfides. In the presence of oxygen-rich waters, these sulfide minerals can undergo oxidative dissolution, releasing the arsenic back into the water to join that liberated by the weathering of the surface. Iron oxyhydroxides would form in such an environment, however, and these will sorb and remove arsenic from the water once again. In waters rich in organic-carbon, reducing conditions can return periodically. This would lead to reductive dissolution to liberate the arsenic from the iron oxyhydroxides. However, these conditions can also reduce sulfates to sulfides and thus reprecipitate the arsenic sulfide minerals. Furthermore, the extremely rapid formation of sedimentary rock during the Flood would likely bury both the original sulfide minerals and the arsenic-sorbed iron oxyhydroxides before they could be significantly dissolved. The modern distribution of arsenic gives evidence of this; the element is often concentrated in large sedimentary basins adjacent to orogenic belts. It appears that arsenic sulfides (formed during the Flood) were in some cases subject to uplift during orogenesis associated with the Flood and underwent oxidation, resulting in the arsenic being sorbed to iron minerals and clays. These eroded into the foreland basins and were buried before the arsenic could leach into local waters to a major degree. In modern times, however, reductive dissolutions of these deposits has resulted in arsenic poisoning. While arsenic does not threaten the Flood model (rather the Flood explains the modern distribution of arsenic), modern arsenic contamination is an ongoing result of the judgement of the Flood

An Evidence Based Methodology for Cultural Institutions Seeking to Identify and Profile their Local Populations

This is the author accepted manuscript. The final version is available from Taylor & Francis (Routledge) via the DOI in this record.Community is a term utilised in policy to describe a collective target audience for public services. Political requirements mean that delivering direct and indirect benefits to local people is regarded as essential to obtaining public sources of funding for cultural organisations. Regardless of any external pressure, cultural organisations strive to be conscious, receptive or inclusive of the views of the public. This paper summarises how a robust approach was developed to identify and profile groupings of residents within an area in relation to their local civic museum (UK). This method resulted in a nuanced understanding of a museum’s local population, identifying groupings upon which to base its future plans. Crucially, the methods outlined in this paper are transferable to cultural institutions in different settings worldwide. Our discussion contributes to the wider endeavour of evidencing impacts of museums on variously defined communities

Ageing validation of northern carp populations

The Carp is considered a threat to our native river fish and ecosystems by its ability to adapt to almost any fresh water body and through its feeding and breeding habits, change environmental parameters such as turbidity, light and water temperatures. This project forms part of the Invasive Animal CRC's freshwater program and is part of a strategy to develop control measures for carp. The age and size at maturity for carp in the northern part of their range (ie. Queensland) is currently unknown

Conductivity in organic semiconductors hybridized with the vacuum field

Organic semiconductors have generated considerable interest for their potential for creating inexpensive and flexible devices easily processed on a large scale [1-11]. However technological applications are currently limited by the low mobility of the charge carriers associated with the disorder in these materials [5-8]. Much effort over the past decades has therefore been focused on optimizing the organisation of the material or the devices to improve carrier mobility. Here we take a radically different path to solving this problem, namely by injecting carriers into states that are hybridized to the vacuum electromagnetic field. These are coherent states that can extend over as many as 10^5 molecules and should thereby favour conductivity in such materials. To test this idea, organic semiconductors were strongly coupled to the vacuum electromagnetic field on plasmonic structures to form polaritonic states with large Rabi splittings ca. 0.7 eV. Conductivity experiments show that indeed the current does increase by an order of magnitude at resonance in the coupled state, reflecting mostly a change in field-effect mobility as revealed when the structure is gated in a transistor configuration. A theoretical quantum model is presented that confirms the delocalization of the wave-functions of the hybridized states and the consequences on the conductivity. While this is a proof-of-principle study, in practice conductivity mediated by light-matter hybridized states is easy to implement and we therefore expect that it will be used to improve organic devices. More broadly our findings illustrate the potential of engineering the vacuum electromagnetic environment to modify and to improve properties of materials.Comment: 16 pages, 13 figure
