The purpose of this longitudinal study was to predict /r/ acquisition using acoustic signal processing. 19 children, aged 5-7 with inaccurate /r/, were followed until they turned 8 or acquired /r/, whichever came first. Acoustic and descriptive data from 14 participants were analyzed. The remaining 5 children continued to be followed. The study analyzed differences in spectral energy at the baseline acoustic signals of participants who eventually acquired /r/ compared to that of those who did not acquire /r/. Results indicated significant differences between groups in the baseline signals for vocalic and postvocalic /r/, suggesting that the acquisition of certain allophones may be predictable. Participants’ articulatory changes made during the progression of acquisition were also analyzed spectrally. A retrospective analysis described the pattern in which /r/ allophones were acquired, proposing that vocalic /r/ and the postvocalic variant of consonantal /r/ may be acquired prior to prevocalic /r/, and /r/ followed by low vowels may be acquired before /r/ followed by high vowels, although individual variations exist.

The objective of this thesis is to further understand the obstacles that impoverished families face, which may include: meeting nutritional needs, an earlier introduction to violence, or struggles with family planning. It is crucial to illustrate the effects of poverty on the physical, mental, and emotional health of both children and caregivers. Additionally, the family dynamics and educational challenges for children will also be explored as supplemental research. This study will draw upon psychological theories with an emphasis on maternal and child health. The goal is to empower families to make informed family planning decisions. This project will be focused on supporting families in low-income areas, particularly in Arizona

The study investigated unconscious biases in physicians regarding conflicts in developing care plans for patients related to religious restrictions in medicine. Fourteen physicians were interviewed to discuss their experiences with these patients and find patterns and factors that could lead to more negative attitudes from the physicians in the patient’s care. It was found that the gender, religious background, and location of residency had various impacts on the attitude of the physician regarding a religious concern; however, there was no outstanding demographic that led to a comparatively negative attitude. Additionally, the type of reasoning a patient used related to a religious concern had an impact on the attitude of the physician, and this was due to the logic and duration of the concern as well as the attitude of the patient. These factors and patient cases were thoroughly analyzed and discussed throughout the paper to shed light on possible factors that could negatively affect the patient’s care.

Schizophrenia is a mental health disorder that affects an individual's ability to function per societal expectations, leading to the onset of stigmatization and discrimination. This can affect the course and outcome of the individual's diagnosis, which impacts several aspects of life, including interpersonal relationships, self-care, and medical attention. Reclassifying the term "schizophrenia" can create a better understanding of the disorder's symptoms and increase funding and research to alleviate the stigmatization currently affecting individuals with this diagnosis.

Alcohol use disorder is a major problem worldwide and can result in a number of significant physical, social and economic consequences. Specifically when comparing the prevalence of alcohol use disorders in the United States and Spain, it is much higher in the United States, at 13.9% compared with 1.5% in Spain. While there are a number of factors that contribute to a person’s risk, this thesis focuses on possible cultural explanations for these differences. After analyzing current literature surrounding alcohol trends and differing cultures in the US and Spain, the differences could be attributable to the dry drinking culture in the US, and the culture surrounding university - living and college towns in the US. The findings of this study suggest that culture, norms and attitudes surrounding drinking have a large impact on alcohol use disorder, and the US could benefit from implementing strategies to change these norms and attitudes surrounding alcohol, as well as train healthcare providers to have effective, brief counseling conversations.
