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
Impact of Simulated Insect Defoliation and Timing of Injury on Cabbage Yield in Minnesota
In 1992 and 1994, field studies were done to assess the tolerance of transplanted cabbage to simulated insect defoliation and to determine if the defoliation level and growth stage at which defoliation begins influences final yield. In both years, 6 defoliation levels ranging from 0-100% were applied to transplanted cabbage at 4 time intervals. The time intervals began at transplanting, pre-head and head stages and continued until either head stage or harvest. For both years, the only time interval with significantly higher yield than the trans- plant to harvest interval (longest interval) was the head to harvest interval (shortest interval) and significant yield loss occurred only when defoliation was \u3e12.5%. Results suggest that transplanted cabbage can withstand relatively low levels of defoliation before yield loss occurs but that yield loss is also related to the duration over which defoliation occurs. In early growth stages, to protect yield, pest management practices should focus on reducing the interval over which damage occurs. The use of cultural practices that delay the onset of defoliation or allow avoidance of pests could protect yield. These strategies may include using transplants to shorten the time from planting to harvest or using planting dates that allow significant plant growth (i.e., head stage) before defoliators are able to infest the crop and cause significant damage. In addition, management strategies that reduce pest populations can also protect yield but at the head stage should switch to managing pests to protect marketability by reducing aesthetic damage and head contaminants
Early-Season Phenology and Temporal Dynamics of the Common Asparagus Beetle, \u3ci\u3eCrioceris Asparagi\u3c/i\u3e (Coleoptera: Chrysomelidae), in Southern Minnesota
During the years 1991-1994, studies were conducted to determine the early-season phenology and temporal dynamics of Crioceris asparagi (L.) (Co- leoptera: Chrysomelidae) in southern Minnesota asparagus. To document the early-season phenology, asparagus plots were sampled for egg, larval, and adult stages of C. asparagi during the months of May and June. Temporal dynamics of C. asparagi were determined by measuring the diurnal activity of adults and sampling asparagus plots at specific times (7 am, 9 am, 11 am, 1 pm, 3 pm and 5 pm) throughout May and June. We first detected C. asparagi adults in early May and they remained active throughout the sampling period. Eggs and larvae were also found; larval infestations on spears, however, were consistently lower than those for eggs. The temporal dynamics of C. asparagi adults showed that a higher percentage of asparagus plants were observed to be infested with beetles during the afternoon hours of 1 and 5 pm. The information provided in this paper illustrates the importance of determining the optimum time of day for sampling and will assist in properly targeting sampling efforts in future asparagus research and integrated pest management (IPM) programs
Intrusion Detection Systems for Community Wireless Mesh Networks
Wireless mesh networks are being increasingly used to provide affordable network connectivity to communities where wired deployment strategies are either not possible or are prohibitively expensive. Unfortunately, computer networks (including mesh networks) are frequently being exploited by increasingly profit-driven and insidious attackers, which can affect their utility for legitimate use. In response to this, a number of countermeasures have been developed, including intrusion detection systems that aim to detect anomalous behaviour caused by attacks. We present a set of socio-technical challenges associated with developing an intrusion detection system for a community wireless mesh network. The attack space on a mesh network is particularly large; we motivate the need for and describe the challenges of adopting an asset-driven approach to managing this space. Finally, we present an initial design of a modular architecture for intrusion detection, highlighting how it addresses the identified challenges
Gender Differences in the Macrostructural Narrative Language of Second Grade African American Children
There is evidence that a racial and ethnic gap in achievement exists in the US. Recently, a gender achievement gap has begun to gain increased attention. The gender gap is more pronounced in African American and Hispanic American populations than in other racial and ethnic groups. Males tend to achieve poorer academic outcomes than females across academic domains. This descriptive study focuses on narrative ability differences between second-grade African American females (n = 8) and males (n = 5). Students generated a spoken narrative from the wordless picture book, Frog, Where Are You? Narrative ability was assessed using the Narrative Scoring Scheme which measures the quality of narrative macrostructure—the hierarchical organization of the narrative. The NSS measures the extent to which each of the following macrostructural components is produced in the narrative: Introduction, Character Development, Mental States, Referencing, Conflict/Resolution, Cohesion, and Conclusion. Results revealed no group differences in macrostructural narrative language ability. These findings indicate that narration may be an area of linguistic strength for African American males.College of Arts and SciencesDepartment of Social and Behavioral SciencesNo embarg
