Traveling Waves In Biological Population Models, Ahlam Alzahrani

Theses and Dissertations

In this thesis, we examine the existence of traveling waves in population models. We begin by exploring conditions under which traveling waves exist, even when the migration probability lacks a density function or, if the density function exists, it may be discontinuous. To address this, we impose certain conditions that ensure the monotonicity of the evolution operator, enabling the application of the Monotone Iteration Method. Next, we explore the existence of monotone traveling waves in a general class of integral-difference population models that depend on both the previous state and long-term memory, allowing for the consideration of multiple past states. …

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 …
