Investigating Acculturation, Health-Promoting Lifestyle, And Health Status Among Nigerian Immigrants In The United States, Frank Uche Akpati

UNLV Theses, Dissertations, Professional Papers, and Capstones

The United States has a significant number of immigrants from Africa. More come from Nigeria than other African countries. Even though acculturation influences health behavior in other cultures, this relationship is understudied in the Nigerian immigrant community in the United States which can influence their health care. This study examined the relationship between acculturation, health-promoting lifestyle, and health status of Nigerian immigrants. Key constructs from Berry’s acculturation model guided the study. Acculturation was conceptualized as occurring through varying levels of ethnic society immersion (ESI) and dominant society immersion (DSI). The study also examined the influence of education on acculturation using …

Axon Initial Segment Morphology Across Typical Cortical Development And In Mouse Models Of Neurodevelopmental Disorders With A High Incidence Of Epilepsy, Rachel Ali Rodriguez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Neurodevelopmental disorders (NDDs) are commonly associated with a high incidence of epileptic seizures which result from excessive firing of neurons. The axon initial segment (AIS) is a neuronal compartment essential for the control of activity patterns of neurons. The AIS undergoes important modifications during development, but the molecular mechanisms that affect the development, morphology, and protein composition of the AIS are still not well understood. We examined AIS morphology of medial prefrontal cortex (mPFC) pyramidal neurons in wildtype mice across development and in two mouse models of NDDs. Results indicate restructurings at the AIS during typical development, some of which …

The Experience Of Self-Coherence: Self-Coherence As The Hub Of All Needs, April Ursula Fox

UNLV Theses, Dissertations, Professional Papers, and Capstones

Self-coherence as the hub of all needs is a novel proposition made by Carol Dweck (2017), and not yet further explored. While supporting self-coherence with a comprehensive review of its presence within behavioral sciences, Dweck does not dive deeper into it, and offers an invitation for further research of its workings. In this study I respond to that invitation. I design a continuation to her theory. I also expand her theory to include what I have found to be missing, but essential, additional components that cannot be ignored within the context of self-coherence as a master sensor of needs. Finally, …

The Role Of Working Memory In Fraction Arithmetic: Eye Movements During A Dual Task, Krystal Kamekona-Mendoza

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fractions are first introduced at the elementary school age, yet difficulty with fraction computation (i.e., adding, subtracting, multiplying, and dividing) continues to persist throughout adulthood. Research suggests that fraction knowledge is predictive of future math achievement and success in algebra. Given the early age at which this concept is introduced and the critical role that it plays in future mathematics success, it is important to better understand the cognitive mechanisms involved in fraction computation and why students continue to struggle with this concept. The role of executive function (e.g., attention, inhibition, working memory) in fraction arithmetic is complex. While working …

Strategic Social Media For Small Congregations, Heather R. Sparkman

Theses

Utilizing social media to draw and build a community of followers is the typical work of the modern Influencer and large organizations. But for a small church, using social media may seem like a wasteful or exasperating experience due to the sheer work that is involved in the enterprise and inconsistency brought on by a lack of strategic thought. The development of this assessment and philosophical metric focuses less on statistical metrics and more on stable principles that relate to values, context, and culture.

Introduction: From Solidão, To Isolation, To Solidão-Rity, Luciane Ramos Silva, Tanya Saunders, Sarah S. Ohmer

Publications and Research

Solidão is a concept from Black Brazilian Gender Studies that does not have a US Black feminist or queer of color equivalent, nor does it translate into a single word in the English language. It describes shared isolation as an affective relational phenomenon with meanings as multiple as there are Black women. Solidão is inherent to the experiences of Black women considering the historical, social, and racial vectors that traverse individual experiences.

But how do you frame intersectional theory with Afro-Atlantic and African knowledge production outside of the United States? This is an introduction to the 2021 special issue of …

Do Loneliness And Social Isolation Predict Mortality Because Of Hazardous Drinking?, Jussi Tanskanen, Sarah N. Arpin, Cynthia D. Mohr

Psychology Faculty Publications and Presentations

Introduction: Subjective feelings of loneliness and objective social isolation have been consistently connected with ill-health and mortality, though little work has empirically examined the mechanisms explaining the adverse effects. This study examines whether alcohol consumption explains the connection of loneliness and social isolation on mortality in different age and gender groups.

Methods: The sample comprised a representative 1994 Finnish sample (n = 8,650) matched with 22-year follow-up mortality data. A multigroup path analysis with discrete survival time analyses was conducted.

Results: There were unique differences in the associations between loneliness, social isolation, alcohol consumption, and mortality based on age and …

Emotion Regulation Variability And Relationship Functioning In Emerging Adulthood, Laura B. Kenneally

Psychology Theses & Dissertations

Emotion regulation is a transdiagnostic factor that functions as a crucial contributor to individual well-being and social functioning. Research seeking to identify adaptive or maladaptive strategies of emotion regulation has often focused on individual strategies, though emerging evidence suggests that what constitutes “adaptive” regulation is often context-dependent. Having a large repertoire of emotion regulation strategies that one is willing to use at different rates has been termed “emotion regulation variability,” and has been linked to positive individual outcomes. While the benefits of emotion regulation variability have been demonstrated on an individual level, the impact on romantic relationships has yet to …

Matchthem: Matching And Weighting After Multiple Imputation, Farhad Pishgar, Noah Greifer, Clémence Leyrat, Elizabeth Stuart

The R Journal

Balancing the distributions of the confounders across the exposure levels in an observational study through matching or weighting is an accepted method to control for confounding due to these variables when estimating the association between an exposure and outcome and reducing the degree of dependence on certain modeling assumptions. Despite the increasing popularity in practice, these procedures cannot be immediately applied to datasets with missing values. Multiple imputation of the missing data is a popular approach to account for missing values while preserving the number of units in the dataset and accounting for the uncertainty in the missing values. However, …

Estimating Social Influence Effects In Networks Using A Latent Space Adjusted Approach In R, Ran Xu

The R Journal

Social influence effects have been extensively studied in various empirical network research. However, many challenges remain in estimating social influence effects in networks, as influence effects are often entangled with other factors, such as homophily in the selection process and the common social-environmental factors that individuals are embedded in. Methods currently available either do not solve these problems or require stringent assumptions. Recent works by Xu (2018) and others have shown that a latent space adjusted approach based on the latent space model has the potential to disentangle the influence effects from other processes, and the simulation evidence has shown …
