Examining the Role of Gendered Racial Identity in the Relationship Between Gendered Racism and Psychological Distress in Black Women

Racism, sexism, and other forms of oppression are consequential to Black women's mental health. The current research examines the psychological impact of gendered racism, which is oppression on the basis of both gender and race, and the extent to which gendered racial identity may buffer the association between gendered racism and psychological distress (i.e., anxiety and depressive symptoms) among U.S. Black women. The study includes a sample of 150 Black women (at least 18 years of age or older, mean age = 39.11) recruited using Qualtrics panel service. Women were administered measures of gendered racism, gendered racial identity, and mental health (i.e., anxiety and depression). Data was analyzed through a series of bivariate correlations and moderation analyses using PROCESS macro. Results revealed that gendered racial identity did not moderate the association between gendered racism and mental health. This study advances our understanding of the oppression Black women contend with on the basis of their race and gender and offers insight about the factors that may mitigate the psychological impact of this phenomenon on Black women.

Modeling, Characterization, and Magnetic Behavior of Transition Metal Nanosystems Synthesized in Silicon Using Low Energy Ion Implantation

Magnetic nano-clusters in silicon involving iron and cobalt were synthesized using low energy (50 keV) ion implantation technique and post-implantation thermal annealing. Before the irradiation, multiple ion-solid interaction simulations were carried out to estimate optimal ion energy and fluence for each experiment. For high-fluence low-energy irradiation of heavy ions in a relatively lighter substrate, modeling the ion irradiation process using dynamic code SDTrimSP showed better agreement with the experimental results compared to the widely used static simulation code TRIM. A saturation in concentration (~ 48%) profile of the 50 keV Fe or Co implants in Si was seen at a fluence of ~ 2 × 1017 ions/cm2. Further study showed that for structures with a curved surface, particularly for nanowires, better simulation results could be extracted using a code "Iradina" as the curve geometry of the target surface can be directly defined in the input file. The compositional, structural, and magnetic properties were studied using Rutherford backscattering spectrometry, X-ray photoelectron spectroscopy, X-ray diffraction, atom probe tomography, and vibrating sample magnetometry. Irradiation of high-current (~ 2 μA/cm2) 50 keV Fe ions into Si at a fluence of 2 × 1017 ions/cm2 showed the formation of Fe5Si3 nano structures in the near-surface …

Perceptions of Purity Messaging on Women and Secular Society

Purity culture was a movement created by evangelical Christian organizations in the United States and backed by marketing campaigns, media, churches, and sex education beginning in the 1990s. This movement was founded on the idea that young men and women should remain abstinent before marriage, thereby remaining in a state of "purity" for their future spouse. In purity culture messaging, women were positioned as sexual gatekeepers while men were framed as having little or no control over their sexual impulses, causing most of the purity expectation to fall on women. While the concept of remaining "pure" is not new, purity culture taught a new generation of women to feel ashamed and fearful of their sexuality and existed alongside an increasingly sexualized media landscape. This study analyzes purity culture and anti-purity culture themes that exist within television shows as well as how women perceive purity culture messaging and the effects this messaging had on their lives.

The Perils of Poor Community-Police Relations: Exploring the Link Between Race, Police Perceptions, and Public Trust in Government

This research examines the political implications of community-police relations in the United States by exploring the link between race, perceptions of police performance, and trust in government. Relying on survey data, I examine these relationships for Blacks, Latinos, Asians, and Whites. In addition to examining the broader relationship between community-police relations and institutional trust, this dissertation examines (1) how police perceptions influence individuals' comfort in contacting the police, (2) how police violence and police perceptions influence trust in government, and (3) the effectiveness of community-oriented policing in building community-police relations and increasing trust in government. First, I find that these relationships are conditional on race and ethnicity. Black respondents, who are more likely to experience negative interactions with the police and who are less likely to have positive perceptions of the police, are less comfortable contacting them. Second, while police violence does not have a significant effect on public trust in government, police perceptions and perceptions of discrimination do. Respondents that perceive the police to be performing well and who do not believe their own racial group is being discriminated against, are more likely to express trust in government. Finally, I find that community-oriented policing has the potential to both …

Parkinson's Disease and UPDRS-III Prediction Using Quiet Standing Data and Applied Machine Learning (open access)

Parkinson's Disease and UPDRS-III Prediction Using Quiet Standing Data and Applied Machine Learning

Parkinson's disease (PD) is a neurodegenerative disease that affects motor abilities with increasing severity as the disease progresses. Traditional methods for diagnosing PD require specialists scoring qualitative symptoms using the motor subscale of the Unified Parkinson's Disease Rating Scale (UPDRS-III). Using force-plate data during quiet standing (QS), this study uses machine learning to target the characterization and prediction of PD and UPDRS-III. The purpose of predicting different subscores of the UPDRS-III is to give specialists more tools to help make an informed diagnosis and prognosis. The classification models employed classified PD with a sensitivity of 87.5% and specificity of 83.1%. Stepwise forward regression indicated that features correlated with base of support were most useful in the prediction of head rigidity (r-square = .753). Although there is limited data, this thesis can be used as an exploratory study that evaluates the predictability of UPDRS-III subscores using QS data. Similar prediction models can be implemented to a home setting using low-cost force plates as a novel telemedicine technique to track disease progression.

Investigation of Room Temperature Soft Ferromagnetism in Indium Phosphide Substrate Synthesized via Low Energy Nickel Ion Implantation

In this work, we have utilized an ion beam process known as gettering to migrate implanted Ni ions much deeper into the bulk substrate than their initial projected end of the range. The projected mean depth is known as Rp. The gettering effect is the most crucial part of the fabrication and we have found that for an H fluence of 3x 1016 cm-2 there is a threshold fluence of approximately 7.5 x 1015 cm-2 that cannot be surpassed if the gettering process is to be completed along with the substrate recovered to the high crystalline quality. This hard threshold is due to the gettering process relaxation induced mechanism that is responsible for migrating the Ni to the Rp/2 location while the H is vacating during the thermal annealing process. If the total number of vacancies produced by the H dissociation is not substantially larger than the total number of implanted Ni atoms the Ni will migrate to the Rp location of the Ni implantation at the amorphous and crystalline interface and toward the surface. When the gettering condition is not met the resulting magnetic responses vary from an exceptionally weak ferromagnetic response to not exhibiting a magnetic response. Additionally, …

Three Essays on Social Media Use and Information Sharing Behavior

Social media platforms create rich social structures, expand users' boundaries of social networks and revolutionize traditional forms of communications, social interactions and social relationships. These platforms not only facilitate the creation and sharing of news and information, but they also drive various kinds of businesses models, processes and operations, knowledge sharing, marketing strategies for brand management and socio-political discourses essential for healthy and democratic functions. As such, social media has greater implications on organizations and society brought about by individuals' social media usage patterns, and therefore, calls for further investigations. The main objective of this dissertation is to explore and offer insights into such social media usage and information sharing behaviors via data driven examination of various theories. This dissertation involves three studies that focus on factors that explain individuals' three different social media usage behaviors. Essay 1 investigates individuals' perceived importance of online affiliation, self-esteem, self-regulation and risk-benefit structure as antecedents of users' geo-tagging behavior on social media. Essay 2 examines the role of online news quality, source credibility, individuals' perception towards online civic engagement, attitude towards news sharing and social influences to understand users' news sharing behavior on social media platforms. Essay 3 seeks to examine the individuals' …

Validation of a survey instrument: team creativity and innovation (C/I) processes as complex adaptive systems (CAS)

Companies are becoming increasingly dependent on teams to drive creativity and innovation, which usually involves multiple teams working together to solve complex problems However, the first problem is that work teams do not always manage creativity and innovation well, especially when partnering with other work teams on highly complex projects that demand greater interdependence and collaboration, which can constitute as much as 90% of today's organizational projects. The second problem is that researchers struggle to define and measure creativity and innovation for the past decade resulting in significant variation both within and between creativity and innovation scales that have restricted meaningful theoretical discoveries and advances. The current study is significant because it introduces a novel instrument derived by John Turner that measures team creativity and innovation processes as a single unit, thereby raising the level of theoretical sophistication and leading to better practical applications. After conducting factor analysis, the current study validates six factors, including 36 indicators, and measures team creativity and innovation processes as complex adaptive systems (CAS). The current study recommends deploying the new instrument in other sectors beyond the IT sector and using multilevel techniques that include the individual and executive/organization levels of analysis.

Intersectional Analysis of Perceived Racism as a Determinant of Children's Mental Health

Youth in the United States are experiencing a steep increase in mental health issues. Concurrently, unique political, economic and social dynamics in the U.S. make the circumstances of nonwhite children's mental health partially contingent on experiences of racism. In this study, I examine the relationship between racial minority children's mental health and perceived racism, while also examining the moderating effects of gender on this relationship. I first review prior research which suggest that racism is a salient determinant of several health outcomes among racial minorities and racial minority children, including depression and anxiety. I then review research on both gender and racial socialization and posit possible implications of these differentials on mental health. Considering both the racialized and gendered factors contributing to youth's mental health outcomes, this study fills a gap in previous research by exploring the differences by gender and race in the effect of perceived racism on children's mental health. I use data from the National Survey of Children's Health from 2016 to 2019. Using average marginal effects, calculated from a series of logistic regression models predicting depression, anxiety, behavioral and emotional problems, I find support for previous research which suggests that perceived racism predicts poor mental health …

Continuing the Work of Our Ancestors: Black Radical Leadership and Disruptive Pedagogies in Affirming the Well-being of Black Students

Using Black feminist thought and BlackCrit/critical race theory frameworks, this qualitative study examined Black educators' practices in addressing the behavior of their students in an urban school district. It utilized counternarratives and storytelling to explore the cultural dynamics at play between Black educators and their Black students. The Black educators in this study operated under several behavior systems, including positive behavioral interventions and supports (PBIS), socio-emotional learning (SEL), restorative practices (RPs), and zero tolerance policies (ZTPs). Such systems have been implemented based on research that they have the capacity to train Black students to make appropriate decisions regarding their behavior. These systems are also reinforced under the notion that they create learning spaces which promote academic achievement. Due to their own experiences and understanding about how institutional practices and disciplinary interventions result disproportionately in oppression and violence against Black students, these educators disrupted these practices and utilized cultural approaches that centered Black-ness. In doing so, they were able to address behavior and affirm Black students' well-being. The cultural approaches conceptualized as disruptive pedagogies include aspects of othermothering, otherfathering, critical caring, sermonizing, womanist caring, and Black masculine caring. An analysis of the stories and counternarratives illustrated that Black principals, counselors, and …

Adult Attachment Anxiety and Relationship Satisfaction: The Role of Dedication and Constraint Commitment

Adult attachment has been found to play an important role for romantic relationship satisfaction. Specifically, the existent literature generally suggests that attachment anxiety is negatively related to relationship satisfaction. However, the underlying mechanism for this link still needs further exploration. The present study examined the direct and indirect effect of attachment anxiety on relationship satisfaction via two distinct relationship commitment variables: constraint commitment and dedication commitment. The final sample included 146 unmarried participants who were in a romantic relationship for at least three months. Results of multiple regression analyses on the indirect effect model indicated that attachment anxiety had a significant direct effect on relationship satisfaction as well as a significant indirect effect on relationship satisfaction via constraint commitment. However, the hypothesized indirect effect through dedication commitment was not supported. Findings are discussed from the adult attachment perspective. Counseling implications, limitations, and future research directions are outlined.
