Dancing the Archive: Rhythms of Change in Post-Volcano Identities on Montserrat, West Indies

In this dissertation, I demonstrate how improvisations within the structures of performance during Montserrat’s annual festivals produce “rhythms of change” that contribute to the formation of cultural identities. Montserrat is a small island of 39.5 square miles in the Caribbean’s Leeward Islands, and a volcanic disaster in the 1990s led to the loss of villages, homes, and material possessions. The crisis resulted in mass displacement and emigration, and today’s remaining population of 5,000 is now in a stage of post-volcano redevelopment. The reliability of written archives for establishing cultural knowledge is tenuous, and the community is faced with re-energizing cherished cultural traditions. This ethnographic research traces my embodied search for Montserrat’s history through an archive that is itself intangible and performative. Festivals produce some of the island’s most visible and culturally political events, and music and dance performances prompt on- and off-stage discussions about the island’s multifaceted heritage. The festival cycle provides the structure for ongoing renegotiations of what it means to be “Montserratian.” I focus especially on the island’s often-discussed and debated “triangular” heritage of Irishness, Africanness, and Montserratianness as it is performed during the festivals. Through my meanderings along the winding hilly roads of Montserrat, I explored reconfigurations of cultural memory through the island’s masquerade dance tradition and other festival celebrations. In this work, I introduce a “Cast of Characters,” each of whose scholarly, artistic, and public service work on Montserrat contributes to the shape and transformation of the island’s post-volcano cultural identities today. This dissertation is about the kinesthetic transmission of shared (and sometimes unshared) cultural knowledge, the substance of which echoes in the rhythms of Montserrat’s music and dance practices today.

CHASING THE SINGERS: THE TRANSITION OF LONG-SONG (URTYN DUU) IN POST-SOCIALIST MONGOLIA

Long-song (Urtyn duu) is a prominent Mongolian traditional folk song genre that survived throughout the socialist period (1921-1990) and throughout the political transformation of Mongolia from socialism to democratic capitalism after the Soviet Union was dismantled and terminated its aid to Mongolia in 1990. This dissertation, based on research conducted from 2006 to 2010, presents and investigates the traces of singers' stories and memories of their lives, songs, and singing, through the lens of the discourse on change and continuity in, and as, folk tradition. During the socialist period, this genre was first considered backward, and was then subtly transformed into an urban national style, with the formation of a boundary between professionalism and amateurism among long-song singers and with selective performance of certain songs and styles. This boundary was associated with politics and ideology and might be thought to have ended when the society entered its post-socialist period. However, the long-song genre continued to play a political role, with different kinds of political meaning one the one hand and only slight musical modification on the other. It was now used to present a more nostalgic and authentic new Mongolian identity in the post-socialist free market. Through my investigation, I argue that the historical transition of Mongolia encompassed not merely political or economic shifts, but also a deeper transformation that resulted in new cultural forms. Long-song provides a good case study of the complicated process of this cultural change.

Design and Pilot Study for an Efficient High-Throughput Automated Computer-Vision Guided Intelligent De-Calyxing Machine for Post-Harvest Strawberry Processing

Strawberries harvested for processing as frozen fruits are currently de-calyxed manually in the field. This process requires the removal of the stem cap with green leaves (i.e. the calyx) and incurs many disadvantages when performed by hand. Not only does it necessitate the need to maintain cutting tool sanitation, but it also increases labor time and exposure of the de-capped strawberries before in-plant processing. This leads to labor inefficiency and decreased harvest yield. By moving the calyx removal process from the fields to the processing plants, this new practice would reduce field labor and improve management and logistics, while increasing annual yield. As labor prices continue to increase, the strawberry industry has shown great interest in the development and implementation of an automated calyx removal system. In response, this dissertation describes the design, operation, and performance of a full-scale automatic vision-guided intelligent de-calyxing (AVID) prototype machine. The AVID machine utilizes commercially available equipment to produce a relatively low cost automated de-calyxing system that can be retrofitted into existing food processing facilities. This dissertation is broken up into five sections. The first two sections include a machine overview and a 12-week processing plant pilot study. Results of the pilot study indicate the AVID machine is able to de-calyx grade-1-with-cap conical strawberries at roughly 66 percent output weight yield at a throughput of 10,000 pounds per hour. The remaining three sections describe in detail the three main components of the machine: a strawberry loading and orientation conveyor, a machine vision system for calyx identification, and a synchronized multi-waterjet knife calyx removal system. In short, the loading system utilizes rotational energy to orient conical strawberries. The machine vision system determines cut locations through RGB real-time feature extraction. The high-speed multi-waterjet knife system uses direct drive actuation to locate 30,000 psi cutting streams to precise coordinates for calyx removal. Based on the observations and studies performed within this dissertation, the AVID machine is seen to be a viable option for automated high-throughput strawberry calyx removal. A summary of future tasks and further improvements is discussed at the end.
