Dysfunctional Leadership As A Dynamic And Relational Process, Rory E. Kuhn, S. Burak Ozkum

Faculty Publications – Psychology

First paragraph in lieu of abstract:

The focal article by Ducheyne and De Fruyt (2026) calls for a clear conceptual distinction between toxic and incompetent leadership, proposing that these categories can guide research and practice by reducing ambiguity. Although we agree that this differentiation offers useful conceptual clarity, we contend that it becomes unstable in its application. Dysfunctional leadership unfolds through both temporal fluctuation in leader behavior and relational variation in follower appraisal. These intertwined processes suggest that the same leader may appear toxic in one moment and merely incompetent in another, depending on shifting behavioral cues and the relational …

Lost Before Forgetting: Objective Driving Metrics Track Navigation Deficits Tied To Preclinical Alzheimer's Disease, Yiqi Zhu, Ramkrishna K Singh, Semere Bekena, David C Brown, Chen Chen, Matthew Blake, Jean-François Trani, Ganesh M Babulal

2020-Current year OA Pubs

BACKGROUND AND OBJECTIVES: Navigation is a complex, multisensory process in which subtle changes may emerge before the onset of symptomatic Alzheimer's disease (AD). This study investigated whether navigation abilities were associated with amyloid and tau pathology in cognitively normal older adults.

RESEARCH DESIGN AND METHODS: Among 285 cognitively unimpaired older adults, navigation and objective driving behaviors were assessed using the self-reported Santa Barbara Sense of Direction Scale (SBSOD) and a datalogger, respectively. Amyloid and tau burden were quantified using PET-MRI 2 years post-initial driving data collection. Linear mixed-effects models were used to evaluate the associations between biomarker status and longitudinal …

Anti-Zionism, Antisemitism, Antidiscrimination, Zalman Rothschild

Articles

This Article uses recent anti-Zionism cases as a case study in hostile environment causation. It briefly surveys the approaches to the causation element that courts have taken in other contexts and then examines the anti-Zionism decisions in detail. It finds that courts in these cases have consistently converged on the narrowest variant of the motive-based approach, treating proof of animus—subjective hostility toward Jews—as the operative route to causation. That approach has its attractions. It preserves breathing space for political speech and resists the claim that opposition to Zionism is necessarily hostility toward Jews. But it is not the only approach …

It Takes A Village (To Raise Children’S Privacy), Mason R. Clark

Faculty Articles

Raising children is an expensive and (mostly) rewarding commitment. Many parents, guardians, and caregivers are willing to invest in indestructible car seats, private schools, and organic, farm-fresh, wholegrain, low-sugar, dye-free, naturally flavored foods. Is it reasonable to ask them to invest in children’s privacy? Surely companies can’t expect parents to stand guard at the edge of a digital playground they never built and never (knowingly) agreed to let their children enter.

The digital age has profoundly reshaped children’s privacy. It is hard to imagine listening to a podcast or scrolling on a social media platform without being bombarded by reports, …

Psychological And Clinical Risk Factors For Substance Use In People With And Without Hiv, Joanna M Hobson, Shameka L Cody, Shannon R Gilstrap, Michael A Owens, Myles D Moody, Dyan M White-Gilliam, Stephen Justin Thomas, Emily J Bartley, Burel R Goodin

BackgroundDespite growing concerns, limited research has demonstrated how psychological factors influence substance use in people with HIV (PWH). Therefore, we examined the association between heightened vigilance and substance use outcomes in people with (PWH) and without HIV (PWoH), while accounting for key risk factors.MethodsParticipants (n = 138) were recruited from an HIV clinic and the surrounding community, completing a urine drug screener (UDS) and questionnaires.ResultsPWH reported greater insomnia (

Characteristics Of Cerebral Palsy In The Midwestern Us, Susie Kim, Kelsey Steffen, Lauren Gottschalk-Henneberry, Jennifer Miros, Amy Robichaux-Viehoever, Karen Taca, Bhooma R Aravamuthan

OBJECTIVE: Cerebral palsy (CP) is the most common lifelong motor disability worldwide. Yet, data is limited on how CP manifests in the US. Our objective was to characterize and determine factors affecting functional outcomes in a large population of young people with CP in the Midwestern US.

METHODS: We integrated caregiver and clinician-facing standardized data entry into routine clinical care at a tertiary care CP center (https://bit.ly/CP-Intake-Methodology). We extracted this data for people with an ICD10 diagnosis of CP seen between March 22, 2023 and December 28, 2023 and used it to describe CP characteristics and determine factors affecting the …

Perception Of Dementia Risk Among Black Adults: An Ecological Analysis Of Causal Loop Diagrams With A Structural And Social Determinant Of Health Composite Index, Jean-Francois Trani, Ramkrishna K Singh, Alexis Ib Walker, Semere Bekena, Yiqi Zhu, Ganesh M Babulal, Robbie Hart

2020-Current year OA Pubs

INTRODUCTION: To investigate drivers of dementia risk disparities among older Black Americans using a community-based system dynamics (CBSD) approach.

METHODS: Over 18 months, 234 participants created 36 causal loop diagrams (CLDs) on dementia risk. An ecological analysis compared structural differences across groups based on scores on a structural and social determinants of health composite index (S/SDOH-CI).

RESULTS: Groups in the highest SDOH-CI quantile were more likely to identify key protective pathways linking mental health, substance use, exercise, medication, and community support to reduce dementia risk. In contrast, fewer than 25% of low-SDOH-CI groups identified these connections, and under 15% recognized …

The Association Between Major Depressive Disorder, Plasma Biomarkers Of Alzheimer's Disease, And Mild Behavioral Impairment Among Older Adults, Yiqi Zhu, Jean-Francois Trani, Ramkrishna K Singh, Semere Bekena, Jonathan Williams, Eric J Lenze, Ganesh M Babulal

2020-Current year OA Pubs

INTRODUCTION: Plasma biomarkers and mild behavioral impairment (MBI) are associated with dementia risk, but their relationships with major depressive disorder (MDD) are understudied. This study aimed to examine associations between plasma biomarkers of Alzheimer's disease (AD) and MBI among older adults with and without MDD.

METHODS: Older adults aged ≥65 were recruited from longitudinal studies of depression and AD (

RESULTS: Older adults with MDD were more likely to endorse MBI. After adjustment, Aβ42/Aβ40 and p-tau217/np-tau217 positivity were associated with MBI among those with MDD but not among those without.

DISCUSSION: Neuropsychatric symptoms (NPS) and biomarkers are AD risk factors. …

This secondary data analysis aimed to determine the nature of the relationship between obstructive sleep apnea (OSA) risk, biological age acceleration, and nonspecific chronic low back pain (CLBP). In total, 199 adults aged 18-82 years who filled both STOPBANG and pain questionnaires subsetted for secondary analysis. Based on the STOPBANG questionnaire, 104 had a low OSA risk and 95 had an intermediate or high OSA risk. Dunedin Pace of Aging Computed from the Epigenome (DunedinPACE), Horvath's, Hannum's, PhenoAge, and GrimAge clocks were used to determine biological age and pace of biological aging. Individuals with low OSA risk reported increased DunedinPACE …

Framing The War On Terror: Media Narratives And U.S. Foreign Policy After 9/11, Neva Essex

History and Political Science | Senior Theses

The media plays an essential role in developing an informed public and the shaping of information. Foreign policy and the coverage of the U.S. movements abroad drastically changed with the 9/11 terrorist attacks. This paper seeks to examine the ways in which media coverage of presidential rhetoric in regard to the U.S. response to terrorism changed over the course of the George W. Bush and Barack Obama administrations. With the use of qualitative narrative analysis of print news media sources and official statements made from the White House, this paper will identify the patterns and changes which occurred over the …
