Ana Maria Carvalho

About

Ana Maria Carvalho is a faculty member in the Spanish and Portuguese Department at the University of Arizona. Her research focuses on sociolinguistics, particularly the study of language contact, bilingualism, and code-switching among Spanish and Portuguese speakers. She has contributed to the understanding of Spanish-English code-mixing in bilingual communities, such as those in Los Angeles, and has analyzed the role of language practices in community engagement and identity. Carvalho has also worked extensively on sociolinguistic corpora, including the Corpus de Español en el Sur de Arizona (CESA), which she developed to promote data sharing, accessibility, and social justice in the study of language variation and contact. Her work highlights the importance of preserving and sharing sociolinguistic data to enhance reproducibility and democratize knowledge in the field. Additionally, she has researched the linguistic variation and bilingualism on the Brazilian-Uruguayan border, examining the interaction between Spanish and Portuguese in social and historical contexts. Through her scholarship, Carvalho explores how language policies, social dynamics, and identity shape language use in bilingual border communities, contributing valuable insights into morphosyntactic variation, language contact phenomena, and the sociopragmatic functions of code-switching.

• The Structure of US Spanish

  Routledge eBooks · 2021 · 5 citations

  Senior authorCorresponding

  This chapter adopts a corpus-based approach to examine the structure of Spanish in the US. Specifically, it discusses four morphosyntactic variables (subject pronoun expression, the extension of estar, progressives, and mood selection) and hallmark language contact phenomena most common in bilingual speech such as lexical borrowing, semantic extensions, and multi-word calcs. By reviewing variationist analyses based on US Spanish corpora, this chapter presents evidence that, far from being a mix…

• Developing Community-Based Sociolinguistic Corpora to Promote Social Justice

  De Gruyter eBooks · 2024 · 2 citations

  This chapter explores the many components that are involved in creating a student-based sociolinguistic corpus. Sociolinguistic corpora can be used as tools for social justice in that they promote local (or often stigmatized) varieties of language and students who speak said varieties often experience heightened language pride or greater esteem for their own language. Using the Corpus del Español en el Sur de Arizona (Carvalho 2012-) and the Corpus Bilingüe del Valle (Christoffersen and Bessett…

• DIAGNÓSTICO TARDIO DO TRANSTORNO DO ESPECTRO AUTISTA EM ADULTOS: IMPLICAÇÕES PARA O TRATAMENTO E INTERVENÇÃO

  Revista fisio&terapia. · 2024-11-30 · 1 citations

  articleOpen access1st authorCorresponding

  Introdução: O Transtorno do Espectro Autista (TEA) é um transtorno neuropsiquiátrico com dificuldades sociais e comportamentais, e seu diagnóstico precoce é fundamental para intervenções eficazes. O diagnóstico tardio, especialmente na fase adulta, tem aumentado devido à variabilidade dos sintomas. Objetivo: Este estudo analisou as implicações do diagnóstico tardio do TEA em adultos. Buscou-se identificar os principais desafios encontrados por estes indivíduos para a obtenção deste diagnóstico.…

• Conformal Geometry and Regularization of Disclinations by a Cosmological Constant in $(2+1)$ Dimensions

  ArXiv.org · 2025-09-01

  preprintOpen access1st authorCorresponding

  We investigate the effect of a cosmological constant $Λ$ on the geometry generated by a two-dimensional disclination in a conformal metric framework. For $Λ>0$, we obtain an exact analytic solution of the Liouville-type equation, which regularizes the defect core, preserves the topological charge, and yields a compact space with finite volume and positive curvature. For $Λ<0$, the solution must be obtained numerically and asymptotically approaches $R \to 3Λ< 0$, producing an open hyperb…
