Navigating Displacement: Jewish-Brazilian Identity In Lasar Segall's Encontro, Kendall Evonne Da Silva

Theses and Dissertations

Jewish-Lithuanian artist Lasar Segall's 1924 painting Encontro has historically been interpreted as representing Segall's integration and assimilation into Brazilian society. This reading, however, generally overlooks Segall's experience as an Eastern European Jew living in Brazil during the early twentieth century. In this thesis, I examine the influence of Segall's ethnic background on his art and investigate how Segall appropriates pardo identity in Encontro, not unproblematically, in an effort to convey feelings of alienation and exclusion. Along with looking at his visual art, my analysis incorporates my translations of Segall's essays on Jewishness, which shed light on his relationship to Judaism …

Ethnic Group Affiliation And Perceptions Of Ethnic Russians In Lithuania, Morgan Lindsay Hassell

Theses and Dissertations

There are many factors that influence language acquisition and use, particularly in multilingual environments. The ethnic group affiliation (EGA) of speakers, or the degree to which a speaker identifies with their native language or culture, has been shown to have a significant impact on language use (Gatbonton, Trofimovich & Segalowitz 2009, Zabrodskaja 2015). EGA can also impact the judgments of and attitudes toward these speakers by others (e.g., Trofimovich & Turuševa 2020). Lithuania is a multilingual state with a complex political and linguistic history, particularly in relation to the Russian language and people. In this study, 150 native Lithuanians and …
