Abstract

A Synthesis of Sociological Perspectives on Culture and Social Evolution This paper provides an in-depth exploration of culture as a foundational element in the study of sociology, dissecting its central components—knowledge, language, symbols, values, norms, and material objects—and their profound impact on society. Through the examination of cultural integration and diversity, the analysis foregrounds the dynamic tensions between assimilation and the preservation of subcultures, illustrating how these forces shape identities, relationships, and social cohesion in contemporary contexts. The discussion offers nuanced insights into the processes by which dominant and minority cultures interact, negotiate power, and navigate the challenges of …

Oped: Forced Disappearances In New Mexico 2025, Jennifer Moore, Antoinette M. Sedillo Lopez, Linda Serrato

Faculty Scholarship

Immigration raids and unaccounted-for seizures of human beings are occurring in New Mexico and throughout the country, with increases in their frequency and magnitude as of June 2025. As we celebrate our Independence, every U.S. citizen should do some soul searching–to seek the soul of our nation. We call on our federal elected officials to work to ensure that enforced disappearances do not happen in our beloved country. As elected representatives and educators we demand to know where our constituents are being held and under what allegations. And we ask ICE agents to consider their actions. History did not look …

Abstract

This paper explores the intricate dynamics of class, stratification, and social inequality, emphasizing the interplay of wealth, power, and prestige in shaping individual opportunities and societal outcomes. Drawing on foundational theories from Marxist and functionalist perspectives, it examines the mechanisms by which economic and social structures reinforce or challenge class divisions. The analysis extends to the evolution of American economic disparity, particularly during the transformative 1980s, and examines policies aimed at addressing poverty, such as those articulated by Sar Levitan and the implementation of the Social Security Act. Through a nuanced discussion of cultural capital, the role of …
