This dissertation examines male bereavement in medieval literature, expanding the current understanding of masculinity in the Middle Ages by investigating both the authenticity and affective nature of grief among aristocratic males. My focus is on the pattern of bereavement that surfaces across genres and that has most often been absorbed into studies of lovesickness, madness, the wilderness, or more formalist concerns with genre, form, and literary convention, but has seldom been discussed in its own right. This pattern consists of love, loss, grief madness and/or melancholy, wilderness lament/consolation, and synthesis and application of information gleaned from the grieving process, which is found is diverse texts from the twelfth century romance of Chrétien de Troyes' Yvain to the fifteenth century dream vision/consolatio Pearl. A focused study of how bereavement is represented through this pattern gains us a deeper understanding of medieval conceptions of emotional expression and their connections to gender and status. In other words, this project shows how the period imagines gender and status not just as something one recognizes, but also something one feels. The judgments and representations of bereavement in these texts can be explained by closely examining the writings of such religious thinkers as Augustine and Aquinas, who borrow from the neo-Platonic and Aristotelian schools of thought, respectively, and both of whom address the potential sinfulness and vanity of excessive grief and the dangers for this excess to result in sinful behavior. This latter point is also picked up in medical treatises and encyclopedic works of the Middle Ages, such as those of Avicenna and Isidore of Seville, which are also consulted in this project. The medieval philosophical and medical traditions are blended with contemporary theories of gender, authenticity, and understanding, as well as an acknowledgement of the psychoanalytic contributions of Freud and Lacan. Through these theories, I explore the capacity for the men in these texts to move beyond the social strictures of masculinity in order to more authentically grieve over the loss of their loved ones, which often constitutes a type of lack. However, my purpose is not to view losses as lack, but rather, to see them as a positive impetus to push beyond the limits of social behavior in order to realize textually various outcomes and to suggest the limitations of such socially sanctioned conventions as literary forms, language, rituals, understanding, and consolation to govern the enactment of grief.

DICTIONARY OF STORMS is a collection of poetry that explores the dynamics of one family through their son’s absence. Using recurring images of skin, water, dragonflies, and pearls, the poems examine distance and absence, wanderlust and filial obligation from different family members’ perspectives. Desires are sloughed off, replaced by new ones, re-cultivated as mythos. The architecture of many individual poems, and the collection as a whole, are structured by meditative lyricism reminiscent of Li-Young Lee. Robert Hass’s poems and translations serve as a model for articulating both the difficulty and beauty of longing. Personae such as “Admonishing Brother Returns as Chrysanthemum” and “Hungry Brother Returns as Octopus” are influenced by Ai and Louise Glück. In the spirit of Emily Dickinson and John Keats, DICTIONARY OF STORMS reflects upon longing, grief, and desire.

Biochar amendment to agricultural soils has been promoted for use in agricultural systems, both to mitigate global warming by increasing long-term soil carbon (C) sequestration and to enhance soil fertility and crop productivity. The objective of this study was to evaluate the effects of a single biochar application from peanut shell (Arachis hypogea L.) and mixed pine (Pinus spp.) wood to a Typic Hapludults in Blacksburg (VA, USA) and from peanut shell and eucalyptus (Eucalyptus camaldulensis) wood to a tropical, sandy, salt-affected soil in Ndoff (Fatick, Senegal) at 0, 10, and 20 Mg ha⁻¹ on soil chemical properties, inorganic nitrogen supply, and pearl millet production responses under field conditions for two growing seasons (2014 and 2015). Biochar application to temperate soils (Blacksburg) significantly increased total soil carbon, nitrogen, and plant available potassium in both years. In addition, pearl millet yields significant increased (53%) at the 20 Mg ha⁻¹ rate of peanut shell biochar in 2014 but did not persist in year 2. Beneficial effects largely appeared due to nutrient additions. Biochar treatment to tropical, sandy, salt-affected soils (Ndoff) had no effect on soil chemical properties. These results suggest that biochar application could improve soil fertility and crop productivity in temperate soils but had limited effects on tropical, sandy, salt-stressed soils in this study. The disparate results between these two field studies could be explained by differences in soil properties and climate, biomass feedstock, pyrolysis processes, and biochar handling, as well as experimental set-up. / Master of Science
