William Bill Hooks, Interviewed by Edith Gordon
No full textWilliam Hooks, a publisher and author of children\u27s books, is interviewed here in 1975 by Edith Lisolette Gordon who was conducting oral histories that would inform her doctoral dissertation on the history of progressive education at Bank Street. Hooks, who grew up in North Carolina, joined the Bank Street Research Division in 1958, simultaneously staging opera workshops at Brooklyn College and doing freelance dancing and writing. He discusses moving to the Bank Street Publications Division in the early 1960s and working on the Early Childhood Discovery Materials with Irma Black, the process of publishing an ethnically integrated series and creating audiovisual materials for children, and more.

Do arbuscular mycorrhizal fungi stabilize litter-derived carbon in soil?
No full text1. Fine roots and mycorrhiza often represent the largest input of carbon (C) into soils and are therefore of primary relevance to the soil C balance. Arbuscular mycorrhizal (AM) fungi have previously been found to increase litter decomposition which may lead to reduced soil C stocks, but these studies have focused on immediate decomposition of relatively high amounts of high-quality litter and may therefore not hold in many ecological settings over longer terms. 2. Here, we assessed the effect of mycorrhizal fungi on the fate of C and nitrogen (N) contained within a realistic amount of highly C-13-/N-15-labelled root litter in soil. This litter was either added fresh or after a 3-month incubation period under field conditions to a hyphal in-growth core where mycorrhizal abundance was either reduced or not through rotation. After 3 months of incubation with a plant under glasshouse conditions, the effect of turning cores on residual C-13 and N-15 inside the cores was measured, as well as C-13 incorporation in microbial signature fatty acids and N-15 incorporation of plants. 3. Turning of cores increased the abundance of fungal decomposers and C-13 loss from cores, while N-15 content of cores and plants was unaffected. Despite the difference in disturbance that turning the cores could have caused, the results suggest that mycorrhizal fungi and field incubation of litter acted to additively increase the proportion of C-13 left in cores. 4. Synthesis. Apart from stimulating litter decomposition as previously shown, mycorrhizas can also stabilize C during litter decomposition and this effect is persistent through time
Nutrient balance and salinity stress in arbuscular mycorrhizal fungi
No full textEarth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. I especially focused on salinity problems, as they occur in southern Tunisia, where I performed several field studies. The following main results were obtained: • The spores of arbuscular mycorrhizal fungi (AMF) may contain high amounts of mineral nutrients. Therefore, our results indicate that AM fungal spores do not only serve for carbon storage, but also as mineral nutrient reservoirs. Both high environmental P concentrations and low C status of the plant partner led to an accumulation of P and other mineral nutrients in the fungus. We suggest that AMF can control the transfer of P and hold it back if not provided with sufficient C from the host, and that there must be a feed-back mechanism in the symbiotic C-P exchange. • I found AMF in saline ecosystems in southern Tunisia with at least 17 morphospecies per 40 g soil. The AMF biomass in soil declined with rising salinity Under elevated salinity, AM fungal hyphae and spores contained high amounts of Ca, Cl and K, while Na was found at low levels. The same findings hold true for a salinity stressed G. intraradices grown in in vitro cultures. This led us to suggest that AMF could act as an ion filter for the plant under high salinity, which could explain the high K/Na rates that are often reported in mycorrhized plants growing in saline soils. • Sole osmotic stress had different effects on G. intraradices than salinity stress, which includes both osmotic and toxic ion stress. Sole osmotic stress impaired the growth of the external mycelium and spores more than salinity stress, while the uptake of nutrients from the medium was more reduced by salinity stress caused by NaCl or KCl. This indicates that sole osmotic stress constitutes a high energetic cost in osmoregulation in AMF. • NaCl stress triggered a strong rise in production of glomalin, a protein important for soil structure, while sole osmotic stress did not. Thus, glomalin seems to be a stress response, but not a general one. • Growth of AM external mycelium was strongly stimulated by organic matter addition to the soil, and also the C flow from the plant to the mycelium was higher under organic matter addition. Mineral nutrient addition to the soil also stimulated AMF growth, though to a lesser extent than organic material. Organic matter addition to subtropical soils can therefore be an important soil remedy, since by stimulating AMF growth, it supports the symbiotically associated vegetation, improves soil structure and increases C storage in the soil. • In a revegetation project, double inoculation of Acacia saplings with AMF and Rhizobium in the desert border of the Sahara did not lead to measurable effects on the plants after five years, but the overall survival of the saplings in field after having been raised in a nursery was satisfactory. We suggest that the inoculum needs to be very carefully chosen in order to be compatible with the ecosystem, or that the native soil inoculum should be considered in management practices
The Memory of Architecture in Edith Wharton’s Travel Writings
No full textEdith Wharton was not only the author of novels and short stories but also of drama, poetry, autobiography, interior decoration, and travel writing. This study focuses on Wharton’s symbolic representations of architecture in her travel writings. It shows how a network of allusions to travel writing and art history books influenced Wharton’s representations of architectural and natural spaces. The book demonstrates Wharton’s complex relationship to works of art historians (John Ruskin, Émile Mâle, Arthur C. Porter) and travel authors (Wolfgang Goethe, Henry Adams, Henry James) in the trajectory of her travel writing. Kovács surveys how the acknowledgment of Wharton’s sources sheds light both on the author’s model of aesthetic understanding and scenic architectural descriptions, and how the shock of the Great War changed Wharton’s travel destinations but not her symbolic view of architecture as a mediator of things past. Wharton’s symbolic representations of architecture provide a new key to her travel writings

Proving the Dead: Doubt and Skepticism in the Late Medieval Lives of Saints Æthelthryth and Edith
No full textabstract: Anglo-Saxon women wielded a remarkable amount of power in the early English church. They founded some of the country’s most influential institutions, and modern Christians continue to venerate many of them as saints. Their path to canonization, however, was informal—especially compared to men and women who were canonized after Pope Gregory IX’s decree in 1234 that reserved those powers for the pope. Many of Anglo-Saxon England’s most popular saints exhibited behaviors that, had they been born later, would have disqualified them from canonization. This project examines how the problematic lives of St. Æthelthryth of Ely and St. Edith of Wilton were simultaneously doubted and adopted by post-Norman Christians. Specifically, it considers the flawed ways that the saints, petitioners, and their communities were simultaneously doubted and legitimized by late-medieval hagiographers.Dissertation/ThesisDoctoral Dissertation English 201
