Interview With Ryan Pollock

Ryan Pollock was raised in Jefferson City, Missouri. He was educated at Helias Catholic High School from 2012 to 2016. After graduating, he attended McNally Smith College of Music in St. Paul, Minnesota, from 2016 to 2017 and majored in both guitar performance and music composition. When the school closed down unexpectedly in 2017, Ryan continued his degree at Columbia College Chicago. Currently, Ryan is a senior and majoring in music composition. Ryan has worked as a guitar instructor since 2014. In 2018, Ryan worked with Big Ten Today Show, MissouriNet/Learfield Communications as an assistant director. Between 2018 to 2020, Ryan worked with 88.1 WCRX-FM as a public affairs coordinator. He even hosts a radio show, “The Ryan Pollock Show,” every Wednesday evening, where he interviews local musicians. Also, he is currently working with WGN Radio as a producer and videographer. Ryan also created his recording company, “Kind of Red Records.” In 2020, when the Coronavirus pandemic forced Columbia to lockdown and transfer to remote learning, Ryan could no longer continue to earn his education and host the radio in-person. He presently resides back in his apartment in the South Loop of Chicago to continue his education and work digitally.https://digitalcommons.colum.edu/capturingquarantine/1002/thumbnail.jp

Income Inequality and Marriage

This study examines the extent to which changes in household formation exacerbated income inequality in the United States during the last two generations. Using a time-varying parameter model, the impact on how marriage decisions, changes in human capital, and fertility choices influence inequality are estimated. The estimation results show that marital sorting evolves over time and positively and increasingly affects the degree of income inequality and intergenerational human capital transmission induces path-dependent income distribution dynamics. This suggests that intrahousehold choices explain a substantial proportion of income distribution dynamics.

Development of Nanocomposite Powders for the SLS Process to Enhance Mechanical Properties

In an effort to fabricate prototypes with improved mechanical properties in the dual laser sintering process, functionalized graphite nanoplatelets were added to the PA-12 powder to produce a nanocomposite powder. The PA-12 powder was chosen as the matrix polymer because it has features conducive to laser sintering such as relatively low melting temperature and high mechanical properties. The GNPs were oxidized through a nitric acid treatment to improve the interfacial bonding. The resulting nanocomposite powder was layered and sintered by laser without any sign of agglomeration. Although the result is preliminary, it nevertheless shows the suitability of the nanocomposite powder for the laser sintering process.Mechanical Engineerin
