This study, conducted in a third-grade classroom in Puerto Rico, analyzed the development of literature discussions, in which through dialogues with the teacher and each other, students learn how to discuss, analyze, and reflect upon what they are reading in class, and relate what they learn to their own circumstances. A combination of three theoretical perspectives served as guide: Reader Response Theory (RRT), which addresses how the dialogue featured in literature discussions helped develop understandings about how power, ideology and identity are interwoven in society; Postcolonial Theory (PT) and Critical Race Theory (CRT), which addresses the dynamics and relations of power in neo-colonial contexts, such as Puerto Rico. The research questions were as follows:1. How do literature discussion and critical literacy practices influence students' understandings of social issues? a) How do these discussions about social issues influence students' understandings of Puerto Rican society and identity? b) How do these discussions influence students' understandings of how political relations constitute Puerto Rican reality? c) How do students take action based on their developing understandings of society? I relied on ethnographic methods, such as participant-observation, interviews, and videotapes of literature discussions, to document how the students, with the help of their teacher, develop discourse practices that allow them to reflect, analyze and discuss their readings, and then plan and take social action on the issues they have studied. I used Critical Discourse Analysis (CDA) as a central strategy of analysis, identifying three major categories that formed part of a broader Identity Theme: Personal, Gender, and Social. A significant aspect of the study is that literature discussions of books based on social issues provide multiple opportunities to reflect, create dialogue, and build understanding about who we are in our current society, who the others are, and provide spaces to develop as social agents. This production of spaces for reflecting on reality, central to this study, fosters in the students a deep process of constructing meaning, elaborates their skills and strategies in reading for a critical understanding of texts and related social issues, and enhances their taking of action for social change.

Sensory Modulation Disorder (SMD) reduces a child’s ability to respond to sensory stimuli in the environment in a manner that corresponds to the nature or intensity of the stimulus; this disorder therefore significantly can impact participation in developmentally appropriate play and functional activities. More studies are needed to enhance research in the field of SMD and aid the general community in understanding the disorder and its causes. The purpose of this study was to characterize the prevalence of SMD among Puerto Rican preschoolers and examine the relationship between specific risk factors (socioeconomic status, pre-natal alcohol exposure, low birth weight, preterm delivery, and lead exposure) and SMD in this population. The sample consisted of 141 caregivers of preschool children; 78 were from Head Start programs and 63 were from private preschools. The Short Sensory Profile was used to determine the presence of SMD. A Demographic and Risk Factors Data Sheet was used to obtain information about the risk factors, except for lead exposure, which was measured using results of blood lead levels tests available in the records of Head Start preschoolers. Prevalence of SMD among the total sample, calculated through descriptive statistics, was 19.9%, which is higher than previously reported estimates of studies with children on the US mainland. According to an Analysis of Variance test, no differences were found in the prevalence of SMD based on parents’ education and/or household income. Diverse multivariate analyses, including structural equation modeling, were used to determine the relevance of risk factors used to explain variance in SMD scores. Due to limitations of the data collected, it was not possible to provide a definite conclusion about the most relevant risk factors identified in this study. In general, when compared to the other risk factors included, findings point to household income and low birth weight as relevant variables to explain scores on the SSP for the total sample. For the Head Start sample, lead exposure and low birth weight, followed by household income, achieved the better relative relevance to explain scores in the SSP (when compared to the other risk factors considered). However, due to the low effect sizes and low percentage of shared variance found among the variables, findings from this study do not support strong associations between risk factors and SMD as suggested in previous literature. More research is required to further understand SMD and the complex interaction among potential risk factors that might be associated with its prevalence.

Puerto Rican women experience increased risk of bio-psychosocial challenges due to their ethnicity. This phenomenological study examined Puerto Rican HIV-positive women's perceptions of intimate partner violence (IPV), which consists of physical, sexual, verbal, and psychological abuse. Although HIV-positive status and IPV have been a focus of previous research, specific research examining the phenomenological experiences of HIV-positive Puerto Rican women who experienced IPV has not been studied. The basis of the study was feminist intersectionality theory, which supported the process used to explore and understand the essence of the participants' experiences. Feminist intersectionality theory examines intersecting social systems including gender, ethnicity, and cultural influences in assessing the lived experiences of the participants. Purposive sampling was used to recruit six participants. Data collection consisted of in-depth, audio-recorded interviews, and data were analyzed by transcribing interviews to explore common themes. Some of the themes that evolved from the research findings are traumatic experiences, feelings about the abuse, reaction to the abuse, trust issues, cultural influences, and positive life changes. The results of this research study provided valuable information of the participants' lived experiences. This research may provide domestic violence specialists, health care providers, law enforcement providers, public advocates, and government agencies with explanation and understanding of the unique challenges Puerto Rican women face. This research has the potential to impact social change in improving IPV screening, offering bi-lingual and bi-cultural service providers, and educating individuals in the helping profession of the impact of IPV.

This dissertation analyzes the representation of sugar plantation societies in nineteenth and twentieth century Puerto Rican literature. Using an interdisciplinary approach, I study the socio-historical, political, and economic development of the sugarcane industry in Puerto Rico as represented in the literary works of Manuel Zeno Gandía, Enrique A. Laguerre, René Marqués, and Rosario Ferré. Scholars have tended to examine their works separately; however, I study how these writers from different literary generations develop a cohesive literary project, reshuffling the periodization of Puerto Rican literature by their focus on the sugar industry. Consequently, the literary works intersect with each other to provide a complete picture of the evolution and decline of the sugar plantation and its effects on the social imaginary of Puerto Rico. I use this term to mean both social practices of Puerto Rican society as well as its class stratification and political struggles. My theoretical approach is based on Antonio Benítez Rojo, "The Repeating Island: The Caribbean and the Postmodern Perspective" (1992), where the sugar plantation is defined as the principal unifying entity across the Caribbean, repeated continuously through time and space. I also rely on socio-historiographical approaches developed by Ramiro Guerra, Francisco Scarano, and Ángel Quintero Rivera, whose analyses of the sugar cane industry in the Caribbean shed light on class conflicts, primarily between the sugar oligarchy and factory workers. This dissertation suggests a homology between the socioeconomic structure of the sugar plantation and the Puerto Rican literary canon. I conclude that Puerto Rican writers have recoded the imaginary of the plantation in response to political events and economic shifts within the sugar industry. While Manuel Zeno Gandía and René Marqués promote and redefine its value system, other writers, such as Enrique A. Laguerre and Rosario Ferré, have transgressed the hacienda system to articulate the voice of those communities marginalized by the sugar plantation.

A review of the literature indicates that Latinos lag behind Whites and Blacks in college degree attainment. This educational disparity is of concern because Latinos are currently the largest minority group in the United States, and the Latino population is expected to increase exponentially in the future. College degree attainment for Latinos is imperative because statistics show an undeniable relationship between degree attainment and income level. In order to ensure the economic wellbeing of Latinos, it is important that Latinos persist through college degree programs. This is especially true for Puerto Ricans because they are the second largest Latino subgroup. The majority of college persistence and departure literature applies to students in general and some of the studies focus on Latino College students. However, fewer studies explore the perspectives of Latinos with the process of graduate or doctoral degree attainment. This is especially true of Latinos of specific ethnic backgrounds such as Cuban, Mexican, or Puerto Rican. I conducted this study in order to address this gap in the literature. This study described and explained the perspectives of a purposive sample of Puerto Rican doctoral graduates on their education by exploring those social and cultural factors that influenced their perceptions, and served as educational facilitators or barriers to their doctoral attainment. The questions that guided the study were: 1.What are the components of their perspectives? and; 2. What social-cultural variables influenced their perspectives?  In order to answer the research questions, I interviewed eight Puerto Ricans with doctorates who were affiliated with the GOTHAM educational system in the state of New York. In order to collect the data, I went to New York in February and March 2010 and conducted face to face interviews with the participants, which were recorded. After I recorded the interviews, I transcribed the data, which I analyzed using a software program called Atlas.ti. I analyzed the data by coding the excerpts, which I identified as the subthemes or variables of this study. The subthemes were coalesced into major themes, which were validated by peer review, several iterations of member check, and data triangulation. After coming to a consensus at all levels of validation, I determined that the emergent themes were in fact evidence of the components of the perceptions of the participants‟ experiences with doctoral attainment. Those components are Personal Factors, Social Role Factors, Cultural Factors, and Social Factors. Based on the analysis of the data, the most profound influence to the perception of the participants‟ lived doctoral experiences was that of the interaction of being a doctoral student, or Adult Learner, with at least one other social role. The most commonly reported negative interaction was being an Adult Learner and a Worker at the same time. Having a lack of Finances, No Latino Role Models, experiencing Negative Events by Ethnicity, and struggling with Self-Efficacy served as barriers to most of the participants. Having Peer Networks and Faculty Support served as facilitators to most of the participants. In order to add to the usefulness of this study, I asked the participants for their advice to future or current doctoral students, and for suggestions to faculty and administrators of higher education. I included their responses as part of this study.

Improvisation is regarded as the most sublime element in the jíbaro folk music tradition of Puerto Rico. This tradition originated by the jíbaro, the simple rural farmer of Puerto Rico's heartland, involves the complicated art of improvising in décima, a ten-line poetic form, as well as improvisation of melodic lines played on the cuatro, a small guitar-like instrument. Since jíbaro improvisation is an art that is transmitted orally and involves a seemingly spontaneous act, it might seem odd to talk about a theory of improvisation within this style of music. My ethnographic research however has revealed that improvisation in jíbaro music is actually a highly structured performance practice and involves an informal theory that is based on the knowledge of archetypal patterns that generate and organize jíbaro improvisations.Recent theories of music which establish parallels between music, language, and cognition (Lerdhal and Jackendoff; Clarke; Gjerdingen) have lead me to believe that improvisation in jíbaro music is generated by the combination of archetypal patterns that create a musical syntax. These patterns are stored in minds of jíbaro performers as cognitive schemas. My study is also based on the work of Puerto Rican scholars Luis M. Alvarez and Angel Quintero who have identified African rhythmic patterns as the generative musical source in many styles of Puerto Rican folk music. By combining theories of music and ethnographic methods, this paper will provide a greater understanding of orally transmitted cultural expressions, which utilize improvisation, as well as give insight to the cognitive processes that shape this performance practice.

This dissertation research showcases six ethnographic case studies that focus on the experiences of Puerto Rican transnational youths and their families upon returning from the US to Puerto Rico. Puerto Rico is a remarkable setting to study transnationalism because of its particular historical and sociopolitical relationship with the US, which grants Puerto Ricans citizenship and thus ease of movement, while retaining a strong attachment to the Island. It can be argued that Puerto Ricans define transnationalism, being simultaneously insiders and outsiders to the US national scene. The youths involved in these dynamics learn to navigate different educational and social settings on the Island and the US. Factors like language and the educational contexts are highly influential in the students' lives and their educational outcomes. The study was conducted over a period of seven months in two public schools in Puerto Rico. The data were collected through interviews, classroom observations, and home visits with return migrant students, their parents, and their teachers and school staff. The combination of these data collection methods and the variety of participants, provided a nuanced portrayal of the nature of their transnationalism and the social and educational experiences of the families in and out of the school context.

According to the Puerto Rico Health Department as of January 2008, 258 cases of HIV, ages 10 -19 had been reported and 224 cases of AIDS, ages 13-19 (Puerto Rico Health Department, 2008). The purpose of this research was to describe the basic social processes of medication adherence in Puerto Rican youth who are HIV positive. Three research questions were proposed: 1) What are the basic social processes of medication adherence in Puerto Rican youth who are HIV- positive?; 2) What factors influence medication adherence (or nonadherence) among HIV- positive adolescents?; 3) What behaviors indicate that the HIV- positive adolescents adhere or do not adhere to their prescribed medications? The Autonomy Development of Adolescence by Steinberg provided the theoretical framework for this study. Grounded theory was used to study 13 Puerto Rican HIV-positive adolescents. Data collection included semi-structured, in-depth interviews, field notes, participant observation, and a demographic questionnaire. A substantive theory Striving to Live a Normal Life, with the core category of normal emerged from data analysis. Striving to Live a Normal Life explains how these Puerto Rican HIV-positive adolescents try to integrate their HIV status and treatment with their lives. These adolescents concentrate their lives on striving to live a normal life. A variety of ways is used to deal with HIV and has helped them visualize themselves as a normal adolescent with a normal life. Because they see themselves having a normal life, taking or not taking their medications for HIV is also seen as a normal part of their lives. This study suggests the beginning of understanding the concept and process of normalization in this population. These findings support the findings in a study done with HIV-positive adolescents from France in which the concept of normality was related to their lives. It also informs interventions to promote improved medication adherence among Puerto Rican youth who are HIV -positive.

The present study consisted of two parts: (1) The examination of whether demographic differences in utilization of multiple forms of health services existed among Non-Hispanic Whites, Mexican-, Cuban-, and Puerto Rican-American adolescents. (2) The examination of whether the Andersen model, revised for Latino adolescents, fit equally well for Mexican-, Cuban-, and Puerto Rican-Americans. Data for this study were drawn from the first two waves of the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative sample of 7th through 12th-grade students in the United States collected between 1994 and 1996.Logistic regression analyses indicated that there were significant differences in routine physical exams based on ethnicity. Mexican-American adolescents were less likely than Non-Hispanic White, Cuban-American, and Puerto Rican-American adolescents to receive routine physical exams. Finding based both on the logistic regressions and on the latent mean comparisons suggested that Cuban- and Puerto Rican-American adolescents are more likely to utilize health services than Mexican-American adolescents. Cuban-American adolescents were also less likely to indicate the need for medical services, whereas Mexican-American adolescents were more likely to state that they needed medical services but were unable to receive them.The results of multi-group confirmatory factor analyses provide mixed evidence toward the indication that the revised Andersen's conceptual model is an appropriate overall framework to utilize with Mexican-, Cuban-, and Puerto Rican-American adolescents. Based on the structural equation model findings, it appears that the major link between need and use of health care services is not supported in the three Latino subgroups. The Andersen model only partially addressed health care needs among the adolescent Latino subgroups. Although there are connections from the main predisposing predictors (including Latino adolescent-specific characteristics) to enabling resources and need, these indirect associations do not necessarily predict use of health services with Mexican-, Cuban-, and Puerto Rican-American adolescents. Clearly there is a great need for health care services among Latino adolescents, particularly given their health disparities in adolescent risk behavior; however current models need further revision, such as including key cultural factors and social context, to predict use of health care services.
