Integrating Background Music into Instructional Videos to Support Learner Engagement and Motivation
Full text linkThis strategy explores how integrating background music (BM) into instructional videos enhances learner engagement and motivation by aligning musical elements with multimedia learning principles. The implementation involved designing seven videos with expert narration, purposeful music composition, and sound effects to guide attention and support pacing without causing cognitive overload. Results showed increased learner attentiveness and motivation, with positive outcomes across all dimensions of Keller’s ARCS model. Practical recommendations for integrating music into online courses are included
Incorporate Peer Review Feedback to Enhance Personal Reflection
No full textPeer review feedback is a utilitarian strategy and great practice in any course. Providing peer reviews has significant advantages including having to make judgements about peer submissions requiring a higher taxonomy of knowledge about the material, resulting in increased understanding. Additionally, this teaches students mistake avoidance, improving skills as well as increasing motivation. This entry provides details about an assignment which asks students to personally reflect and then offer supportive feedback to peers regarding their leadership development

Hemiballismus Secondary to Acute Cerebrovascular Accident
No full textHemiballismus is a rare hyperkinetic movement disorder characterized by involuntary, large amplitude flinging movements. We present the case of a 61-year-old male with multiple comorbidities who arrived at the emergency department with acute-onset hemiballismus of the left upper extremity, ultimately found to be secondary to a right middle cerebral artery (MCA) infarct. This case underscores the importance of considering stroke in the differential for new-onset movement disorders, even in patients with seemingly psychiatric features and a nondiagnostic initial computed tomography (CT) scan
Becoming Black in a Divided Diaspora: Identity, Human Security, and the Intra-Group Dynamics of African Americans and African Immigrants
No full textThis dissertation examines the formation of a shared Black identity among Native Black/African Americans and African immigrants in the United States through an expanded intersectional framework that integrates Social Identity Theory (SIT), Intergroup Contact Theory, and Secondary Marginalization Theory, all under the broader lens of human security. Human security is broadly defined as the protection of individuals from critical threats to their dignity, survival, and livelihood. It is deeply implicated in the experiences of Black communities confronting systemic racism and social exclusion. This study conceptualizes shared identity as a socio-psychological construct and a protective mechanism that enhances group-level resilience and collective agency in the face of structural threats. The theoretical framework combines intergroup contact mechanisms with perceived racial discrimination to examine how shared identity develops within racially grouped but ethnically diverse Black communities. While racial categorization imposes boundaries, positive intra-Black interactions and recognition of common struggles (e.g., anti-Black discrimination) serve as unifying forces that reinforce group cohesion. This work extends Social Identity Theory by demonstrating that shared identity is not static, even within a racially labeled group; it is dynamically negotiated through interethnic experiences, thereby reflecting an intersectional theoretical synthesis. This study employed a mixed-methods design. The quantitative analysis draws on original survey data collected in 2023 from over 600 Native Black/African American respondents via the platform Prolific, and ordered logistic regression was used to assess three dependent variables: Global Black Identity, Pan-Black Identity, and Global Black Solidarity. Predictors included the
perceived quality of interactions with African immigrants and agreement on shared racial discrimination. Qualitative in-depth interviews were conducted with first-, first-and-a-half-, and second-generation Nigerian immigrants. The results show that negative stereotyping and cultural distancing undermine identity formation, reinforcing Secondary Marginalization within Black populations. Yet, racial discrimination from dominant out-groups paradoxically contributes to shared Black identity development. These findings demonstrate how the intersectional forces of race, ethnicity, and immigration status interact to shape identity outcomes. This research contributes to identity scholarship by demonstrating how intra-group ethnic relations and sociopolitical forces jointly influence identity formation and human security. In highlighting both challenges and pathways to unity within the Black diaspora, the study offers critical implications for coalition politics, public policy, and community resilience. Ultimately, tensions between African Americans and African immigrants underscore the need to frame shared Black identity as a strategy for advancing human security in the face of fragmentation and systemic threats

Parents’ Adverse Childhood Experiences and Young Children’s Behavior Problems: Examining Protective Moderating and Mediating Factors
No full textAdverse childhood experiences (ACEs) are childhood exposures to abuse, neglect, and household dysfunction. ACEs have been linked to a cumulative negative impact on later adult physical and psychological well-being. Parents who carry ACEs often have difficulties in parenting, which have, in turn, been linked to young children’s internalizing and externalizing behavior problems. Nonetheless, some parents who carry ACEs develop positive parenting strategies. Very little is known about how such outcomes occur. A growing area of research concerns protective and compensatory experiences (PACEs) that buffer against the negative consequences of ACEs. PACEs may improve deficits in cognitive, emotional, and neurobiological systems brought about by early exposure to stress and trauma. The relationship between PACEs and parenting strategies, including how they relate to young children’s internalizing and externalizing behavior problems, has yet to be examined. Correlational, moderation, and moderated mediated analyses were conducted for 204 parents. Results suggested that PACEs moderate the relationship between parents\u27 ACEs and young children’s internalizing and externalizing behavior problems. Parents’ ACEs were related to young children’s behavior problems through emotional availability. Parents’ ACEs also were related to their young children’s behavior problems through reflective functioning. There was a suggested moderating effect of PACEs on the relationship between ACEs and protective parenting behaviors. The implication of these findings are discussed
Printability and Phase Transformation of Selected Alloys Additively Manufactured By Laser Powder Bed Fusion
No full textThe integration of laser powder bed fusion (LPBF) to produce critical engineering components, aimed at achieving reduced weight and enhanced efficiency, has sparked significant interest in the field of additive manufacturing (AM). LPBF is highly desirable due to its rapid production capabilities, minimized material waste, and its ability to facilitate intricate engineering designs. The ongoing challenges associated with processing metals free of cracks while attaining high relative density remain central to advancing AM technology. This has led to a continued interest in alloy development for LPBF given the limited selection of alloys currently available. This study seeks to evaluate the printability of selected alloys and understand the cracking mechanism through the application of the solidification cracking criterion. An in-house laboratory-scale gas atomizer was employed to produce gas-atomized powders of carbon-bearing steels and eutectic multi-principal element alloys (EMPEAs). The compositions of the carbon-bearing alloys were modulated to yield either austenite or martensite in the as-printed condition to understand the printability and evaluate the applicability of the hot cracking susceptibility criterion. Selected EMPEA compositions were modified in reference to the pseudo-binary phase diagrams to evaluate their printability. Systematic investigations were conducted to assess the effects of processing parameters on the microstructure and flaw formation. Hot cracking in a high carbon-bearing steel is consistent with the hot cracking susceptibility criterion while the observed cracking formation in EMPEAs is driven by thermal residual stress
Health Behavior in a Culture-Driven Society: Using Mixed Methods Research to Examine Medical Pluralism in Zimbabwe
No full textThis dissertation examined the role of cultural influences on health-seeking behaviors and healthcare choices among Zimbabweans, focusing on medical pluralism – where individuals simultaneously access traditional, faith-based, and allopathic medical systems. It applied the PEN-3 Cultural Model to examine Cultural Identity, Relationships and Expectations, and Cultural Empowerment. Using a convergent parallel mixed-methods design, data were collected via a Shona-language survey on WhatsApp. Multiple choice, closed-ended, and open-ended survey questions were texted to participants, and they responded by text or audio messages. Response data were collected from 137 study participants. Multinomial logistic regression was used for quantitative data analysis, while deductive coding was used for qualitative thematic analysis.
Quantitative analysis found that Cultural Empowerment (LR Chi²(9) = 68.14, p \u3c .001) and Cultural Identity (LR Chi²(9) = 37.95, p \u3c 0.001) significantly influenced medical pluralism, with Relationships & Expectations having a lesser impact (LR Chi²(9) = 16.02, p = 0.0666). Qualitative results showed a preference for medical pluralism driven by Cultural identity and Cultural Empowerment but also undertones of individual autonomy. Participants also expressed a desire for confidentiality of personal health information accompanied by a resentment to involve too many people in individuals’ health issues.
Study findings offer valuable insights into participants’ health behavior, with implications for formulation of appropriate health policy. Limitations included a small sample size, reducing statistical power and effect detection. Non-probability sampling limited generalizability. It underscores the need for healthcare systems that integrate culturally diverse healthcare practices to improve outcomes. Involvement of immediate family, extended family, and neighbors as triggers of entry into health care must be balanced with confidentiality. Future research should use larger, random samples to mitigate these shortcomings
