ARAB MUSICIANS IN WASHINGTON, D.C. AREA: ETHNICITY AND IDENTITY

Musicians living in the Arab Diaspora around the Washington, D.C. metro area are a small group of multi-faceted individuals with significant contributions and intentions to propagate and disseminate their music. Various levels of identity are discussed and analyzed, including self-identity, group/ collective identity, and Arab ethnic identity. The performance and negotiation of Arab ethnic identity is apparent in selected repertoire, instrumentation, musical style, technique and expression, shared conversations about music, worldview on Arabic music and its future. For some musicians, further evidence of self-construction of one's ethnic identity entails choice of name, costume, and venue. Research completed is based on fieldwork, observations, participant-observations, interviews, and communications by phone and email. This thesis introduces concepts of Arabic music, discusses recent literature, reveals findings from case studies on individual Arab musicians and venues, and analyzes Arab identity and ethnicity in relation to particular definitions of identity found in anthropological and ethnomusicological writings. Musical lyrics, translations, transcriptions, quotes, discussions, analyses, as well as charts and diagrams of self-identity analyses are provided as evidence of the performance and negotiation of Arab identity.

A mathematical description of the acoustic coupling of the mass/spring model

This paper describes hybrid mathematical model which couples the mechanics of the mass/spring model to the acoustic wave propagation model for use in generating the acoustic signal emitted by complex structures of paper fibres under strain. A discussion of the coupling method is presented including remarks on the errors encountered intrinsic to the discretisation scheme. The numerical results of a vibrating rubber band and a vibrating paper fibre are compared to their experimental counterparts. The fundamental frequencies of the acoustic signals are compared showing a close agreement between the experimental and numerical results

Plankton Of The Fladen Ground During Flex-76 .1. Spring Development Of The Plankton Community

Results from plankton sampling in the northern North Sea with the Continuous Plankton Recorder (CPR) and the Undulating Oceanographic Recorder (UOR) during the Fladen Ground Experiment in 1976 (FLEX 76) are summarised. The first evidence of the spring outbreak of phytoplankton was on 19 April, the day after the first signs of vertical stability of the water column were observed. This was followed by spawning of the euphausiid Thysanoessa inermis and rapid increase in the numbers of Calanus finmarchicus. C. finmarchicus was the most abundant species over the FLEX period (19 March to 3 June) and, together with T. inermis, accounted for over 80% of the dry weight of the zooplankton standing stock. By early June the standing crop of phytoplankton had been depleted and nutrients levels were reduced to very low concentrations in the upper 50 m.
