Exploring Microplastic Concentrations And The Sedimentology Of San Diego's Offshore Benthic Environments, Rachel Sarner

Theses

Marine pollution studies are showing infiltration of plastic debris in remote parts of oceans including the deep sea. Microplastics (MPs) are being discovered not only in the ocean’s water column but also benthic sediments reaching thousands of meters in depth. This is the first study to analyze MP concentrations in conjunction with sedimentary characteristics from varying deep-sea environments (coastal, deep ocean, offshore terrace) in the Southern California Continental Borderland (CCB). Our goal for this study was to observe how the concentration and type (morphology, color, size) of microplastics varied with distance from shore, with water depth, and between different submarine …

Strategic Behavior, Artistic Integrity, And Tradeoffs In Popular Music, Andrew Weinbach, Phillip Kamau Njoroge, Robert Salvino, Arch Woodside

Finance and Economics

This study examines market concentration's influence on popular music. The data cover popular music from weekly Billboard Hot 100 songs from 1952 to 1989, for which song characteristic data including tempo and duration is available from the Million Song Dataset (MSD). Greater market concentration of the top four artists is found to impact song length, with longer #1 songs and shorter songs in the #2 through #10 spots on the Billboard charts. However, tests for alterations in song construction by top artists that might indicate a form of “sell-out” behavior do not reveal evidence of it.
