Reflections on Children

In the Fall 2004, while preparing my dissertation project “Reflections on children,” I realized that whether art songs, operatic arias or scenes, the classical repertory offers a wide variety of masterpieces regarding all aspects of children’s life. My first dissertation recital is called “Journeys” and was performed on December 6th 2004 at 8:00pm in the Tawes Recital Hall. Change is the only inevitable condition in life and as such, it has been thought-provoking to many poets and composers. The narrator in Mahler’s Wayfarer Songs experiences the pain of love for the first time and emerges transformed into an adult. The narrator in Barber’s Knoxville is an adult looking back at his journey in an attempt to understand himself. The mothers in Britten’s Charm of Lullabies each make every effort to accept the changes in their own life after the birth of her baby. Finally, both Brahms’ songs are about risks and losses. “Destinies” is the title of the second dissertation recital as it attempts to capture the dark fate of Mignon and of Rückert/Mahler’s children. It was performed on April 8th 2005 in the Tawes Recital Hall. Mignon’s grief is portrayed through songs full of sadness and hopelessness in mourning of a long lost childhood. Rückert wrote 425 Kindertotenlieder in memory of his children’s deaths over a period of twenty years and Mahler orchestrated five of them. Mahler’s choices deal with light and darkness, symbolizing eternal life and hope versus despair and death, in both the literal and the literary sense. Finally, the third dissertation recital called “Blessings” was performed on May 19th 2005 in the Tawes Recital Hall. It relies on the evocation of moods and scenes created by a variety of composers and poets. Poulenc’s La Courte Paille are brief works in the style of a child’s song with unrelated and unexpected images juxtaposed, creating a sense of inner monologues. John Greer’s House of Tomorrow, Guastavino’s Cradle Songs and the rest of the composers offer wonderful pieces of immense power and expression in their directness and sensitive contour.

The Effect of Supportive Social Interaction Priming on Children's Prosocial Comforing Responses to Distressed Others

The ability to sensitively care for others’ wellbeing develops early in ontogeny and is an important developmental milestone for healthy social, emotional, and moral development. One facet of care for others, prosocial comforting, has been linked with important social outcomes such as peer acceptance and friendship quality, underscoring the importance of determining factors involved in the ability to comfort. Although social support has been linked with a number of important social outcomes, no study has directly examined whether felt social support can foster children’s positive behavior toward others. The purpose of the current investigation was to use an experimental priming paradigm to demonstrate that felt social support a) enhances children’s ability to respond prosocially to the distress of others and b) decreases children’s expressions of personal distress when faced with the distress of another person. Participants were 94 4-year-old children (M = 53.56 months, SD = 3.38 months; 52 girls). Children were randomly assigned to either view pictures of mothers and children in close, personal interactions (supportive social interaction condition), happy women and children in separate pictures, presented side-by-side (happy control condition), or pictures of colorful overlapping shapes (neutral control condition). Each set of 20 pictures was presented in the context of a categorization computer game that participants played 4 times throughout the course of the study. Immediately following the first three computer games, children were given the opportunity to comfort someone who was distressed; twice it was the adult experimenter working with the child, and once it was an unseen infant crying over a monitor that participants had been trained to use. Comforting behaviors and distress/arousal were coded in 10-second time segments and yielded a global comforting score and a distress proportion score for each task. Results indicated that priming condition had no effect on either prosocial comforting behavior or expressions of personal distress. I discuss these null findings in light of the available literatures on priming mental representations in children and on prosocial comforting, and suggest some future directions for continued investigation in both fields.

Interactive Effects of Plant Species and Organic Carbon on Nitrate Removal in Chesapeake Bay Treatment Wetlands

Nitrate from agricultural runoff are a significant cause of algal blooms in estuarine ecosystems such as the Chesapeake Bay. These blooms block sunlight vital to submerged aquatic vegetation, leading to hypoxic areas. Natural and constructed wetlands have been shown to reduce the amount of nitrate flowing into adjacent bodies of water. We tested three wetland plant species native to Maryland, Typha latifolia (cattail), Panicum virgatum (switchgrass), and Schoenoplectus validus (soft-stem bulrush), in wetland microcosms to determine the effect of species combination and organic amendment on nitrate removal. In the first phase of our study, we found that microcosms containing sawdust exhibited significantly greater nitrate removal than microcosms amended with glucose or hay at a low nitrate loading rate. In the second phase of our study, we confirmed that combining these plants removed nitrate, although no one combination was significantly better. Furthermore, the above-ground biomass of microcosms containing switchgrass had a significantly greater percentage of carbon than microcosms without switchgrass, which can be studied for potential biofuel use. Based on our data, future environmental groups can make a more informed decision when choosing biofuel-capable plant species for artificial wetlands native to the Chesapeake Bay Watershed.
