The Role Of Cross-Cultural Connections In Leadership Identity Development: From Entry To Embodiment, Jennifer Okoliko

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Leadership identity development has received considerable attention in the literature, but most of what we know comes from studies focused on students in formal leadership programs or on the mentee’s side of mentoring relationships. Less understood is the mentor's leadership identity development journey and the role of culture in that process.

This study explores how mentors from low power distance cultural backgrounds who engaged with mentees from high power distance cultural backgrounds interpreted the impact of those experiences on their leadership identity development.

Using Interpretive Phenomenological Analysis (IPA), I conducted two semi-structured interviews with ten participants recruited from different formal …

The Procedures And Perceived Impact Of Pastoral Succession In A Family-Led Church: A Case Study, Yvonne H. Hines

Doctoral Dissertations and Projects

Leadership transitions in any viable organization are inescapable and complex. Pastoral leadership is a challenging task whether one is charged with an astronomical or miniscule calculation of individuals. Pastoral succession, one of the most significant leadership undertakings in the Christian church, encompasses the transfer of authority, an indispensable component to the effectual progression of the church. Churches in the United States are presently confronted with a contemporary dynamic in pastoral leadership, family-led churches. Pulpits traditionally filled by denominational officials or congregational elections are currently impacted by the automatic succession of family members as senior pastors in the family-led church setting. …

Project Future: Turner Chapel African Methodist Episcopal Church Leadership Development And Success Planning Project, Tonya Renee Mcclure

Doctoral Dissertations and Projects

This study found that adaptive, relational, and vision-centered leadership approaches significantly enhance emerging leader development and engagement at Turner Chapel AME Church. Grounded in contingency theory (Fiedler, 1967), decision-making theory (Vroom & Yetton, 1973), and Northouse's (2022) transformational and servant leadership concepts, the mixed-methods research integrated quantitative and qualitative data. The findings underscore the essential roles of coaching, strategic organizational design, and spiritual formation in cultivating authentic leaders. Integrating transformational and servant leadership creates a lasting framework for emerging leader development, pointing to the value of intentional, data-driven leadership pipelines within faith-based organizations.

Teaching Online Pedagogical Repository

The AI Resilient Assessment Audit is a quality assurance workflow where instructors use Generative AI to stress test their discussion prompts for vulnerabilities to academic dishonesty. Vulnerable prompts are remediated using a Personal Synthesis Protocol. This protocol requires students to anchor concepts to verifiable episodic memories and engage in structured peer review. This approach shifts assessments from simple recall to self-determined learning and fosters deeper student engagement.

Bilingual Teacher Advocacy, Agency, And Leadership: A Model For Teacher Education And Professional Development, Grace Jue Yeon Kim, Zhenjie Weng, Jingyi Zhu

Faculty Journal Articles

Research has examined bilingual teachers’ work and their

experiences through the theoretical lens of teacher advocacy,

teacher agency, and teacher leadership. This research synthesis

analyzes the current research on the three frameworks in bilingual

education and examines how they intersect. Bilingual teachers

advocated for educational change to address the needs of

emergent bilinguals. Despite various context-specific constraints,

bilingual teachers agentively created bilingual spaces for

linguistically diverse students. Furthermore, bilingual teachers

actively took up leadership roles, demonstrated increased

consciousness, and developed leadership identities. Through this

exploration, this paper proposes a model that integrates the three

frameworks for bilingual teacher education and …

Research outputs 2022 to 2026

S-Methyl cysteine sulfoxide (SMCSO) is an organosulfur compound with demonstrated hypocholesterolemic, anti-diabetic, and antioxidant benefits in rodents. However, the doses used have limited translatability for humans. We explored whether SMCSO could blunt development of diet-induced metabolic syndrome features in mice using doses that are potentially more translatable and achievable in humans. Male mice (C57BL/6; n = 54) were randomly assigned into one of five groups: [1] normal-diet; [2] high-fat-diet; or high-fat-diet with [3] 60 mg kg⁻¹, [4] 170 mg kg⁻¹, or [5] 350 mg per kg per body weight (BW) of SMCSO, respectively. Doses were administered …

Source-Specific Nitrate Intake And Incident Dementia In The Danish Diet, Cancer And Health Study, Catherine P. Bondonno, Pratik Pokharel, Dorit Wielandt Erichsen, Liezhou Zhong, Jörg Schullehner, Cecilie Kyrø, Kirsten Frederiksen, Peter Fjeldstad Hendriksen, Frederik Dalgaard, Lauren C. Blekkenhorst, Stephanie R. Rainey-Smith, Samantha L. Gardener, Torben Sigsgaard, Ole Raaschou-Nielsen, Anne Tjønneland, Jonathan M. Hodgson, Christina C. Dahm, Anja Olsen, Nicola P. Bondonno

Research outputs 2022 to 2026

Introduction: Dietary nitrate, through conversion to nitric oxide, which supports vascular and nervous system function, may lower dementia risk but may also form neurodegenerative N-nitrosamines, depending on the nitrate source. Methods: We investigated associations between source-specific nitrate and nitrite intake and incident and early-onset dementia (< 65 years) in 54,804 dementia-free participants from the Danish Diet, Cancer and Health Cohort Study over ∼27 years. Nitrate and nitrite intakes were derived from food frequency questionnaires and nitrate and nitrite databases. Results: Higher plant-sourced nitrate intake was non-linearly associated with lower rates of incident dementia (fifth vs first quintile hazard ratio 95% confidence interval: 0.90 [0.83, 0.98]), while increased risk was seen for higher intakes of animal-sourced, additive-permitted meat-sourced, and tap water-sourced nitrate. Similar associations were seen for source-specific nitrite intake and were more pronounced for early-onset dementia. No clear effect modification was observed. Discussion: These findings highlight the importance of nitrate source in dementia risk and warrant further investigation. Highlights: Plant nitrate is associated with a lower risk of incident and early-onset dementia. Animal and tap water nitrate are associated with an increased risk of dementia. Encouraging consumption of plant-based nitrate sources may lower risk of dementia.

Networked Behaviors Associated With A Large-Scale Secure Messaging Network: Cross-Sectional Secondary Data Analysis, Laura Rosa Baratta, Linlin Xia, Daphne Lew, Elise Eiden, Y Jasmine Wu, Noshir Contractor, Bruce L Lambert, Sunny S Lou, Thomas Kannampallil

2020-Current year OA Pubs

BACKGROUND: Communication among health care professionals is essential for effective clinical care. Asynchronous text-based clinician communication-secure messaging-is rapidly becoming the preferred mode of communication. The use of secure messaging platforms across health care institutions creates large-scale communication networks that can be used to characterize how interaction structures affect the behaviors and outcomes of network members. However, the understanding of the structure and interactions within these networks is relatively limited.

OBJECTIVE: This study investigates the characteristics of a large-scale secure messaging network and its association with health care professional messaging behaviors.

Amyloid Accumulation, Brain Atrophy, And Cognitive Decline In Emergent Alzheimer's Disease, Ying Xia, Pierrick Bourgeat, Vincent Doré, Jurgen Fripp, Yen Ying Lim, Simon M. Laws, Christopher Fowler, Christopher C. Rowe, Colin L. Masters, Elizabeth J. Coulson, Paul Maruff

Research outputs 2022 to 2026

Introduction : Emergent Alzheimer's disease (AD) represents a transitional stage where cognitively unimpaired (CU) individuals exhibit subthreshold but increasing amyloid-β (Aβ) levels. The impact of Aβ accumulation on brain volume loss and cognition during this early stage remains unclear. Methods: This retrospective cohort study analyzed data from 408 CU participants who were initially Aβ− (< 15 Centiloids) and followed for up to 15 years. Changes in basal forebrain and hippocampal volume, along with domain-specific cognitive performance, were compared between those who progressed to Aβ+ (≥20 Centiloids) and those who remained Aβ−. Results: Sixty-five CU participants progressed to Aβ+, indicating emergent AD, and showed faster Aβ accumulation and subtle memory decline. However, no significant differences in rate of BF and hippocampal atrophy were observed between groups. Discussion: The results suggest that during this emergent phase of AD, Aβ accumulation is associated with episodic memory loss, in the absence of detectable accelerated brain atrophy. Highlights: Identified cognitively unimpaired individuals in the emergent stage of Alzheimer's disease (AD). Emergent AD exhibits a greater rate of amyloid-β (Aβ) accumulation. No accelerated volume loss detected in the basal forebrain or hippocampus. Emergent AD is also associated with a subtle decline in memory. Early Aβ accumulation may impair cognitive function before structural atrophy.
