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 …

Guåhan: A (De)Colonial Borderland (open access)

Guåhan: A (De)Colonial Borderland

Answering the call to decenter whiteness and coloniality within communication studies (#RhetoricSoWhite), this project attempts to reclaim space for indigenous knowledge and to serve decolonial struggles. Written as a project of love for my fellow indigenous scholars and peoples, I expand upon Tiara Na'puti's conceptualization of "Indigeneity as Analytic" and chart how indigenous Pacific Island decolonial resistance operates through a paradigm of decolonial futurity. By recognizing Guåhan (Guam), as well as Chamoru, bodies as (de)colonial borderlands, I demonstrate the radical potential of indigeneity through three different case studies. First, I name indigenous feminine style as a strategic mode of public address adopted by Governor Lou Leon Guerero to resist the spread of COVID-19 by US military personnel on the island of Guåhan. Second, I showcase how the process and practice of indigenous Pacific Island tattooing delinks away from coloniality. Finally, I demonstrate how the celebration of a Chamoru saint, Santa Marian Kamalen, provides a spatial-temporal intervention that articulates an indigenous religion and enacts a decolonial futurity.

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.

The Abraham Solvation Model Used for Prediction of Solvent-Solute Interactions and New Methods for Updating Parameters (open access)

The Abraham Solvation Model Used for Prediction of Solvent-Solute Interactions and New Methods for Updating Parameters

The Abraham solvation model (ABSM) is an experimentally derived predictive model used to help predict various solute properties. This work covers various uses for the ABSM including predicting molar enthalpies of vaporization, predicting solvent coefficients for two new solvents (2,2,5,5-tetramethyloxolane and diethyl carbonate), predicting values for multiple new ionic liquids (ILs). This work also introduces a novel method for updating IL ABSM parameters by updating cation- and anion-specific values using linear algebra and binary matrices.

Gender Role Conflict and Religion/Spirituality (open access)

Gender Role Conflict and Religion/Spirituality

Relatively few studies have explored the relationship between gender role conflict (GRC) and an individual's religious/spiritual identities. This study sought to add to the research on GRC by exploring the experiences of female and male GRC, and expand the understanding of the influence of religion/spirituality (R/S) variables on GRC. Participants (N = 359) were recruited from social media and undergraduate courses and completed an online survey that assessed GRC, a variety of R/S variables, and life satisfaction. Overall, there were some significant differences found between male and female experiences of GRC. In general, the R/S variables did not have a large impact on GRC. However, religious fundamentalism and extrinsic and quest religious orientations were related to specific subscales of GRC. Maintaining congruency between one's personal values and one's religious institution was related to lower levels of specific subscales of GRC. Additionally, GRC was related to lower levels of life satisfaction. Regarding the subscales of GRC, restrictive emotionality was the strongest predictor of lower life satisfaction. By furthering research on the interplay between GRC and R/S, clinicians will be more equipped to handle the repercussions of stereotypical roles within gender and religion, address negative attitudes and behaviors, and lead discussions about …

Antecedents to Reliance on Artificial Intelligence and Predictive Modeling

Artificial intelligence (AI) and predictive modeling are tools used to diagnose a disease, determine how much a home is worth, estimate insurance risks, and detect fraud. AI and predictive modeling are so ubiquitous that they can be why one gets spam and why spam is automatically deleted. Information science integrates interdisciplinary elements of data-driven, behavioral, design, interpretive, and analytical research methodologies to design and understand interactions between digital media, information systems, and humans. This research focuses on the interaction between humans, AI, and predictive models. This research proposes a theoretical framework and a conceptual research model to understand the antecedents to reliance on AI and predictive modeling. The dissertation follows a traditional format that includes three studies. Study 1 employed a deductive quantitative research approach as a survey to model the relationship between trust in science and reliance on formal news sources. Study 2 employed a deductive quantitative research approach as a survey to understand the impact of framing questions and consider an alternative method of measuring society's reliance on science using predictive models. Study 3 employed a deductive quantitative research approach in the form of a survey to posit a new model based on the first two studies. This …

Onboarding Learning Modalities and the Relationships with Onboarding Experience, Locus of Control, Self-Efficacy, and Employee Engagement (open access)

Onboarding Learning Modalities and the Relationships with Onboarding Experience, Locus of Control, Self-Efficacy, and Employee Engagement

Online and hybrid onboarding, or new-hire training and assimilation, has grown increasingly common in corporate settings, especially since the COVID-19 pandemic. This study explores how perceived onboarding experience, work locus of control, occupational self-efficacy, and employee engagement differed between those who onboarded with in-person, hybrid, or online methods. This study also explores how work locus of control could moderate these relationships and examines the relationships between employee engagement and onboarding experience, locus of control, and self-efficacy. This study used quantitative research methods in the form of a self-administered online questionnaire aimed at corporate employees who had onboarded within the previous 18 months. One hundred fifty-three employees completed the survey. It was found that no significant difference in the variables existed between modalities, except for the task characteristic subscale of perceived onboarding experience in which scores were lower for those onboarded in-person. However, work locus of control was found to significantly moderate the relationships between onboarding modality and experience, locus of control, and self-efficacy. Additionally, employee engagement was increased with higher perceived onboarding experience, more internal loci of control, and higher self-efficacy. In addition to the research questions, demographic data were also explored. It was found that perceived onboarding experience was …

Fabrication and Testing of Polymeric Flexible Sheets with Asymmetric Distributed Magnetic Particles for Biomedical Actuated Devices

This thesis explores a method to fabricate magnetic membranes with asymmetric distribution of particles and their testing as actuators. Focus of this research is to fabricate thin polymeric sheets and thickness range of 120-125µm, with asymmetric distribution of magnetic nano particles, employing micromagnets during the fabrication. The micromagnets are used to localize the magnetic particles during the curing process at selected locations. The effect of the asymmetric distribution of magnetic particles in the membrane is used for the first time. Magnetite (Fe3O4) is used as the magnetic particles that is embedded into a polymeric membrane made of polydimethylsiloxane (PDMS); the membrane is then tested in terms of deflection observed by using a high-resolution camera. From the perspective of the biomedical application, PDMS is chosen for its excellent biocompatibility and mechanical properties, and Fe3O4 for its non-toxic nature. Since magnetic actuation does not require onboard batteries or other power systems, it is very convenient to use in embedded devices or where the access is made difficult. A comparative study of membranes with asymmetric and randomly distributed particles is carried out in this thesis. The asymmetric distribution of magnetic particles can benefit applications involving localized and targeted treatments and precision medicine.

CFD Study of Ship Hydrodynamics in Calm Water with Shear Current and in Designed Wave Trails

Although the capability of computational fluid dynamics (CFD) in modeling ship hydrodynamics is well explored in many studies, they still have two main limitations. First, those studies ignore the effect of non-uniform shear current which exists in realistic situation. Second, the focus of most studies was laid more on the seakeeping/maneuvering performance and less attention was paid to survivability of ships due to extreme ship response events in waves, which are considered rare events but influential. In this thesis, we explore the capability of CFD in those two areas. In the first part of the thesis, the hydrodynamic performance of KCS in the presence of a non-uniform shear current is investigated for the first time using high-fidelity CFD simulations. Various shear current conditions with different directions were considered and results were compared with the ones with no shear current. The second part of the thesis focuses on study of rare events of ship responses by development of extreme response conditioning techniques to design the wave trail. Two conditioned techniques based on Gaussian and non-Gaussian processes are considered.

Impact of Processing Parameters and Forces on Channels Created by Friction Stir Bobbin Tools (open access)

Impact of Processing Parameters and Forces on Channels Created by Friction Stir Bobbin Tools

In this thesis, friction stir channeling (FSC) and its process parameters influence on geometry, surface quality and productivity are explored. The probe of the friction stir processing (FSP) tool used to perform these tests was a modified submerged bobbin tool made of MP 159 Co-Ni alloy. The body was made from H13 tool steel. To find the optimal channel conditions for a targeted range of process parameters, multiple 6061 aluminum samples were prepared with a U shape guide to test the effects of different spindle speeds and feed rates. Using a gantry-type computer numerical control (CNC) friction stir welding (FSW) machine, the aluminum coupons were subjected to calibration experiments, force control tests, and an increased production rate to test these effects. It was found through experimentation that the programmed feed rates, spindle speeds and forces produced by the machine had an impact on the channel geometry. It was determined from the force-controlled setup that 8.46 mm/s at 750 RPM was the best combination of results for the four conditions tested on a CNC friction stir processing-machine. It was then tested at 10.58 mm/s at 800 RPM, which had comparable results with the best combination of input parameters from the force-controlled …

The Product is People: An Investigation of Missile Combat Crew Perceptions Surrounding Standardized Training Curriculum

Missile Combat Crew members are officers in the United States Air Force responsible for operating nuclear-tipped intercontinental ballistic missiles. They undergo on-the-job training as part of the curriculum necessary to progress in their careers and achieve higher levels of job responsibility. The curriculum they use is created and maintained by 20th Air Force Test and Training Section. This product is known as the Missile Combat Crew Commander Upgrade program, and it has received criticisms from stakeholders who use it for being out of date and failing to capture the necessary topics for ensuring adequate on the job training is being conducted. This project seeks to examine these critiques, break down the curriculum produced by 20th AF into stages (creation, implementation, and feedback) for evaluation, uses principles of user-oriented design drawing on design anthropology to suggest alternative methods for curriculum creation, and utilizes the results of a diagnostic survey to provide data-driven recommendations to 20th AF for future rewrites of their product based on feedback from the crew members who use their product in the field.

Nothing Short of Really Healthy Children: Mothers, the Children's Bureau, and Disability, 1914 - 1933 (open access)

Nothing Short of Really Healthy Children: Mothers, the Children's Bureau, and Disability, 1914 - 1933

In 1931 the United States Children's Bureau asserted that "nothing short of really healthy children should satisfy parents." This thesis examines how literature published by the Children's Bureau from 1913 to 1933 shaped perceptions of motherhood and of maternal control over the body. As the bureau taught mothers how to care for their children, it also taught them that by following bureau advice, mothers could shape the bodies of their children to adhere to normative body standards. The research considers the relationship between mothers, the state, and the physical body. This thesis is divided into chapters about prenatal care and maternal marking; infant care and maternal policing; and child care and maternal control.

Discriminative Control of Behavioral Variability in Video Game Play (open access)

Discriminative Control of Behavioral Variability in Video Game Play

Creativity can be a useful skill in today's classrooms and workplaces. When individuals talk about creativity, it's unclear what the controlling variables are when we tact behavior as "creative." Research in understanding the processes behind behaviors that are considered "creative" would assist in identifying functional relations and provide insight on how to teach creativity. Since creativity is often described as doing something different from the norm, behavioral variability may be a potential aspect of creativity. This study aimed to replicate previous findings by investigating the effects of discrimination training in a multiple schedule of varied and repetitive responding in the context of a video game. Participants played through a 2D online video game made in Bloxels. Different alternating-colored platforms served as the discriminative stimuli for the vary and repeat components. Three parameters of variability were measured (e.g., left jumps, right jumps, and double jumps). The results of the study indicate that participants were able to learn the discrimination of when to repeat and vary their responses depending on which colored platform they encountered.
