    International trade of electric vehicle batteries and lithium: a network approach to trade structure and structural inequality
    (Colorado State University. Libraries, 2023) DeBruin, Jacob, author; Roberts, Tony, advisor; Luna, Jessie, committee member; Stevis, Dimitris, committee member
    As international efforts toward clean energy transition and climate mitigation have been made, the international trade of emission-reducing technologies and their necessary materials has grown. Few technologies have seen as much growth as electric vehicles and their lithium-ion batteries; and few materials have seen as much growth as lithium. Research on international battery and lithium trade is extensive but has yet to examine the formation of the trade structure and its structural inequality. This study uses bilateral trade data from the UN COMTRADE database and country attribute data from the World Bank database to (1) measure the overall structure of and structural inequality in international electric vehicle battery and lithium trade networks; and (2) analyze determinants of the trade networks' formation. Results indicate that the international trade of electric vehicle batteries and of lithium are characterized by a core-periphery pattern—by which certain countries occupy the center of trade, and by which certain countries occupy the margins—and therefore, that there is an inequality in the distribution of trade relationships among countries participating in battery and lithium trade. The results also indicate that differences in countries' GDP and country's structural position in the networks largely determine the likelihood of trade-relationship formation. Inferentially, the results provide some evidence for (ecologically) unequal exchange in the trade of commodities that ostensibly support clean energy transition and sustainable economic development, like electric vehicle batteries and lithium.

    Multicultural education & perceptions of racial inequity among White Americans: a cohort analysis
    (Colorado State University. Libraries, 2022) Sims, Shelby, author; Roberts, Tony, advisor; Hastings, Orestes P., committee member; Sbicca, Joshua, committee member; Schmidt, Jenne, committee member
    Growing concern over racial injustice in the United States has warranted an investigation into the perceptions of racial inequality among White Americans. The phasal introduction of multicultural education (ME) in the United States has continually increased the exposure of newer cohorts of White Americans to diverse cultures and perspectives of social reality experienced by racial minorities. However, prior studies have neglected to empirically evaluate whether ME improved perceptions of racial inequity among White Americans. Using the General Social Survey (1972-2018), the present study uncovers patterns of changes in perceptions of racial inequity among White Americans. Specifically, I utilize an inter-cohort approach to illuminate patterns of association between ME cohort, educational attainment, and regionality. I conduct a thorough evaluation of the age-period-cohort dilemma in relation to racial attitudes and determine a year fixed-effects model the most empirically consistent model with the data. The multivariate analysis confirms that perceptions of racial inequity have in fact progressed with the implementation of ME. In addition, the results confirmed that more progressive racial perceptions are associated with increased educational attainment and less progressive racial perceptions are associated with Southern adolescence. Neither of these effects is contingent on ME exposure and both operate independently of educational content. The implications of these findings and subsequent recommendations for continued research on ME and White racial perceptions to continue striving for racial equity through public education.
