Beyond the Convent Walls: The Local and Japan-wide Activities of Daihongan’s Nuns in the Early Modern Period (c. 1550–1868)

This dissertation examines the social and financial activities of Buddhist nuns to demonstrate how and why they deployed Buddhist doctrines, rituals, legends, and material culture to interact with society outside the convent. By examining the activities of the nuns of the Daihongan convent (one of the two administrative heads of the popular pilgrimage temple, Zenkōji) in Japan’s early modern period (roughly 1550 to 1868) as documented in the convent’s rich archival sources, I shed further light on the oft-overlooked political and financial activities of nuns, illustrate how Buddhist institutions interacted with the laity, provide further nuance to the discussion of how Buddhist women navigated patriarchal sectarian and secular hierarchies, and, within the field of Japanese history, give voice to women who were active outside of the household unit around which early modern Japanese society was organized.

Zenkōji temple, surrounded by the mountains of Nagano, has been one of Japan’s most popular pilgrimage sites since the medieval period. The abbesses of Daihongan, one Zenkōji’s main sub-temples, traveled widely to maintain connections with elite and common laypeople, participated in frequent country-wide displays of Zenkōji’s icon, and oversaw the creation of branch temples in Edo (now Tokyo), Osaka, Echigo (now Niigata), and Shinano (now Nagano). The abbesses of Daihongan were one of only a few women to hold the imperially sanctioned title of eminent person (shōnin 上人) and to wear purple robes. While this means that this Pure Land convent was in some ways not representative of all convents in early modern Japan, Daihongan’s position is particularly instructive because the existence of nuns and monks in a single temple complex allows us to see in detail how monastics of both genders interacted in close quarters.

This work draws heavily from the convent’s archival materials, which I used as a guide in framing my dissertation chapters. In the Introduction I discuss previous works on women in Buddhism. In Chapter 1, I briefly discuss the convent’s history and its place within the Zenkōji temple complex. In Chapter 2, I examine the convent’s regular economic bases and its expenditures. In Chapter 3, I highlight Daihongan’s branch temples and discuss the ways that they acted as nodes in a network connecting people in various areas to Daihongan and Zenkōji, thus demonstrating how a rural religious center extended its sphere of influence in urban settings. In Chapter 4, I discuss the nuns’ travels throughout the country to generate new and maintain old connections with the imperial court in Kyoto, confraternities in Osaka, influential women in the shogun’s castle, and commoners in Edo. In Chapter 5, I examine the convent’s reliance upon irregular means of income such as patronage, temple lotteries, loans, and displays of treasures, and how these were needed to balance irregular expenditures such as travel and the maintenance or reconstruction of temple buildings. Throughout the dissertation I describe Daihongan’s inner social structure comprised of abbesses, nuns, and administrators, and its local emplacement within Zenkōji and Zenkōji’s temple lands.

Exploring these themes sheds light on the lives of Japanese Buddhist nuns in this period. While the tensions between freedom and agency on the one hand and obligations to patrons, subordination to monks, or gender- and status-based restrictions on the other are important, and I discuss them in my work, my primary focus is on the nuns’ activities and lives. Doing so demonstrates that nuns were central figures in ever-changing economic and social networks as they made and maintained connections with the outside world through Buddhist practices and through precedents set centuries before. This research contributes to our understanding of nuns in Japan’s early modern period and will participate in and shape debates on the roles of women in patriarchal religious hierarchies.

Commandeering Aesop’s Bamboo Canon: A 19th Century Confederacy of Creole Fugitive Fables

In my thesis, “Commandeering Aesop’s Bamboo Canon: A 19th Century Confederacy of Creole Fugitive Fables,” I ask and answer the ‘Who? What? Where? When? Why?” of Creole Literature using the 19th century production of Aesopian fables as clues to resolve a set of linguistic, historical, literary, and geographical enigmas pertaining the ‘birth-place(s)’ of Creolophone Literatures in the Caribbean Sea, North and South America, as well as the Indian Ocean. Focusing on the fables in Martinique (1846), Reunion Island (1826), and Mauritius (1822), my thesis should read be as an attempt capture the links between these islands through the creation of a particular archive defined as a cartulary-chronicle, a diplomatic codex, or simply a map in which I chart and trace the flight of the founding documents relating to the lives of the individual authors, editors, and printers in order to illustrate the articulation of a formal and informal confederation that enabled the global and local institutional promotion of Creole Literature. While I integrate various genres and multi-polar networks between the authors of this 19th century canon comprised of sacred and secular texts such as proclamations, catechisms, and proverbs, the principle literary genre charted in my thesis are collections of fables inspired by French 17th century French Classical fabulist, Jean de la Fontaine. Often described as the ‘matrix’ of Creolophone Literature, these blues and fables constitute the base of the canon, and are usually described as either ‘translated,’ ‘adapted,’ and even ‘cross-dressed’ into Creole in all of the French Creolophone spaces. My documentation of their transnational sprouting offers proof of an opaque canonical formation of Creole popular literature. By constituting this archive, I emphasize the fact that despite 200 years of critical reception and major developments and discoveries on behalf of Creole language pedagogues, literary scholars, linguists, historians, librarians, archivist, and museum curators, up until now not only have none have curated this literature as a formal canon. I also offer new empirical evidence in order to try and solve the enigma of “How?” the fables materially circulated between the islands, and seek to come to terms with the anonymous nature of the texts, some of which were published under pseudonyms. I argue that part of the confusion on the part of scholars has been the result of being willfully taken by surprise or defrauded by the authors, or ‘bamboozled’ as I put it. The major paradigmatic shift in my thesis is that while I acknowledge La Fontaine as the base of this literary canon, I ultimately bypass him to trace the ancient literary genealogy of fables to the infamous Aesop the Phrygian, whose biography – the first of a slave in the history of the world – and subsequent use of fables reflects a ‘hidden transcript’ of ‘masked political critique’ between ‘master and slave classes’ in the 4th Century B.C.E. Greece.

This archive draws on, connects and critiques the methodologies of several disciplinary fields. I use post-colonial literary studies to map the literary genealogies Aesop; use a comparative historical approach to the abolitions of slavery in both the 19th century Caribbean and the Indian Ocean; and chart the early appearance of folk music in early colonial societies through Musicology and Performance Studies. Through the use of Sociolinguistics and theories of language revival, ecology, and change, I develop an approach of ‘reflexive Creolistics’ that I ultimately hope will offer new educational opportunities to Creole speakers. While it is my desire that this archive serves linguists, book collectors, and historians for further scientific inquiry into the innate international nature of Creole language, I also hope that this innovative material defense and illustration of Creole Literature will transform the consciousness of Creolophones (native and non-native) who too remain ‘bamboozled’ by the archive. My goal is to erase the ‘unthinkability’ of the existence of this ancient maritime creole literary canon from the collective cultural imaginary of readers around the globe.

Advanced Aerogel Composites for Oil Remediation and Recovery

Oil spills in marine environments often damage marine and coastal life if not remediated rapidly and efficiently. In spite of the strict enforcement of environmental legislations (i.e., Oil Pollution Act 1990) following the Exxon Valdez oil spill (June 1989; the second biggest oil spill in U.S. history), the Macondo well blowout disaster (April 2010) released 18 times more oil. Strikingly, the response methods used to contain and capture spilled oil after both accidents were nearly identical, note that more than two decades separate Exxon Valdez (1989) and Macondo well (2010) accidents.

The goal of this dissertation was to investigate new advanced materials (mechanically strong aerogel composite blankets-Cabot® Thermal Wrap™ (TW) and Aspen Aerogels® Spaceloft® (SL)), and their applications for oil capture and recovery to overcome the current material limitations in oil spill response methods. First, uptake of different solvents and oils were studied to answer the following question: do these blanket aerogel composites have competitive oil uptake compared to state-of-the-art oil sorbents (i.e., polyurethane foam-PUF)? In addition to their competitive mechanical strength (766, 380, 92 kPa for Spaceloft, Thermal Wrap, and PUF, respectively), our results showed that aerogel composites have three critical advantages over PUF: rapid (3-5 min.) and high (more than two times of PUF’s uptake) oil uptake, reusability (over 10 cycles), and oil recoverability (up to 60%) via mechanical extraction. Chemical-specific sorption experiments showed that the dominant uptake mechanism of aerogels is adsorption to the internal surface, with some contribution of absorption into the pore space.

Second, we investigated the potential environmental impacts (energy and chemical burdens) associated with manufacturing, use, and disposal of SL aerogel and PUF to remove the oil (i.e., 1 m3 oil) from a location (i.e., Macondo well). Different use (single and multiple use) and end of life (landfill, incinerator, and waste-to-energy) scenarios were assessed, and our results demonstrated that multiple use, and waste-to-energy choices minimize the energy and material use of SL aerogel. Nevertheless, using SL once and disposing via landfill still offers environmental and cost savings benefits relative to PUF, and so these benefits are preserved irrespective of the oil-spill-response operator choices.

To inform future aerogel manufacture, we investigated the different laboratory-scale aerogel fabrication technologies (rapid supercritical extraction (RSCE), CO2 supercritical extraction (CSCE), alcohol supercritical extraction (ASCE)). Our results from anticipatory LCA for laboratory-scaled aerogel fabrication demonstrated that RSCE method offers lower cumulative energy and ecotoxicity impacts compared to conventional aerogel fabrication methods (CSCE and ASCE).

The final objective of this study was to investigate different surface coating techniques to enhance oil recovery by modifying the existing aerogel surface chemistries to develop chemically responsive materials (switchable hydrophobicity in response to a CO2 stimulus). Our results showed that studied surface coating methods (drop casting, dip coating, and physical vapor deposition) were partially successful to modify surface with CO2 switchable chemical (tributylpentanamidine), likely because of the heterogeneous fiber structure of the aerogel blankets. A possible solution to these non-uniform coatings would be to include switchable chemical as a precursor during the gel preparation to chemically attach the switchable chemical to the pores of the aerogel.

Taken as a whole, the implications of this work are that mechanical deployment and recovery of aerogel composite blankets is a viable oil spill response strategy that can be deployed today. This will ultimately enable better oil uptake without the uptake of water, potential reuse of the collected oil, reduced material and energy burdens compared to competitive sorbents (e.g., PUF), and reduced occupational exposure to oiled sorbents. In addition, sorbent blankets and booms could be deployed in coastal and open-ocean settings, respectively, which was previously impossible.
