Extending Legal Privilege To In-House Counsel In India, L Viswanathan, Animesh Bisht

National Law School of India Review

Client-attorney privilege is a cornerstone of the rule of law, yet its extension to in-house counsel in India remains fraught with uncertainty. The Supreme Court’s recent decision in In re: Summoning Advocates who give legal opinion or represent parties during investigation of cases and related issues, Suo Moto Writ Petition (Criminal) No. 2 of 2025, reinforced a status-based exclusion, holding that in-house counsel fall outside the definition of “Advocate” under the Advocates Act, 1961 and the Bar Council of India Rules, and therefore cannot claim privilege under the Bharatiya Sakshya Adhiniyam, 2023. This paper examines the Indian statutory framework and …

High-Deductible Health Plans In Rural And Urban Populations: Outpatient Utilization And Out-Of-Pocket Costs, Aaron P. Smith, Jefferey Talbert

Rural & Underserved Health Research Center Publications

Overview of Key Findings This policy brief explores rural-urban differences in High-Deductible Health Plan (HDHP) enrollment, subsequent healthcare utilization, and out-of-pocket (OOP) costs. ▪ HDHP enrollment was uncommon. Rural residents were slightly less likely to enroll than urban residents across all demographic groups. ▪ Switching plans influenced utilization. Compared to those who did not change healthcare plans, switching from a Traditional plan to a HDHP was associated with a larger reduction in 2022 outpatient visits for both rural and urban residents. Moving from a HDHP to a Traditional plan was associated with a smaller reduction in 2022 outpatient visits for …

Nurse Manager Perceptions Of Strategies To Overcome The Underutilization Of Nonpharmacological Pain Control Methods In Adult Acute Care, Landen M. Bonnell

Undergraduate Honors Theses

A basic patient right is to have pain adequately managed. However, research consistently indicates that many adult patients in acute care experience inadequately managed pain, which may contribute to adverse patient outcomes. Studies have shown that nonpharmacological pain management can lead to increased patient satisfaction, shorter hospital stays, and better patient outcomes. However, many barriers exist to nurses providing effective nonpharmacological pain control therapy, primarily including heavy workload and a lack of education and support. Currently, there is insufficient research on how to overcome these barriers. Four nurse managers with experience in nursing leadership were interviewed using a qualitative descriptive …

Online Group Neurobehavioral Therapy (Nbt) For Veterans With Epilepsy And Major Depressive Disorder (Mdd), Melissa F. Fadipe

Dissertations and Theses (Open Access)

Background: Veterans with epilepsy experience high rates of psychiatric comorbidity, most commonly major depressive disorder (MDD). Barriers to accessing mental health care—including geographic distance, transportation limitations related to seizure-related driving restrictions, and fragmented care between neurology and psychiatry, contribute to the underdiagnosis and undertreatment of MDD in this population. Neurobehavioral Therapy (NBT), a Cognitive Behavioral Therapy (CBT)-informed psychotherapy developed for individuals with seizures, has demonstrated benefits for psychological distress and quality of life. Internet-based interventions and short message service (SMS) text messaging offer promising strategies to address access barriers; however, limited research has examined the feasibility and acceptability of delivering …

Baseline Nutrition Knowledge And Feasibility Of A Whatsapp-Delivered Nutrition Education Intervention Among California Wildland-Urban Interface Firefighters, Lauren E. Anderson

Faculty Research 2026

Over the past decade, the Model Organism Development and Evaluation for Late-Onset Alzheimer's Disease (MODEL-AD) consortium has transformed preclinical Alzheimer's disease (AD) research by addressing critical limitations in traditional mouse models that failed to translate to human disease. By leveraging human genetic discoveries, MODEL-AD has developed > 70 genetically informed mouse models, standardized phenotyping pipelines, and an open-access data infrastructure aligned with late-onset AD biology. These models incorporate human risk variants, environmental factors, and aging to better capture disease complexity, including emerging recognition of mixed pathologies such as vascular contributions, Lewy body disease, and TDP-43 proteinopathy. Despite substantial progress, key challenges …

A Collaborative Framework For Uncovering Molecular And Cellular Drivers Of Vcid: Foundations For Future Interventions In Dementia., M Luisa Iruela-Arispe, Jason D Hinman, Andrew C Yang, Fabrice Dabertrand, Jin-Moo Lee, Gareth R Howell, The Vcid Centers Without Walls Network

Faculty Research 2026

Vascular-related factors are now considered major contributors to most forms of dementia, including Alzheimer's disease. However, the degree to which vascular deficits contribute to risk, onset, and progression of cognitive impairment and dementia has only recently been appreciated. Our understanding of the mechanisms by which vascular deficits drive cognitive decline in dementia is still limited. Further, the testing of therapeutic approaches to prevent vascular deficits to treat dementia are few. These factors motivated the establishment of the Vascular Contributions to Cognitive Impairment and Dementia (VCID) Center Without Walls (CWOW) network, comprising institutes across the United States. We describe the current …

Carter, Jessica E Young, Treat-Ad Consortium

Faculty Research 2026

INTRODUCTION: Post mortem proteomic analysis of Alzheimer's disease (AD) brain tissue has identified novel target genes and proteins for potential therapeutic development. Moesin (MSN) and CD44 were identified as candidate targets. Using human induced pluripotent stem cells (hiPSCs)-derived neurons, we assayed how reducing gene expression of MSN and CD44 affected amyloid beta secretion, tau phosphorylation, and transcriptional state.

METHODS: Knockdown of MSN and CD44 in hiPSC-derived neurons was performed using short hairpin RNA (shRNA). Amyloid precursor protein processing and intracellular tau phosphorylation was measured using chemiluminescent ELISA assays. Global gene expression was analyzed by bulk RNA sequencing (RNA-seq).

RESULTS: Knockdown …

Traumatic knee injury leads to posttraumatic osteoarthritis (PTOA) and significant skeletal muscle weakness, resulting in chronic disability. The current standard of care frequently fails to prevent musculoskeletal dysfunction, underscoring the need to identify therapeutic mechanisms of PTOA. Using an established preclinical anterior cruciate ligament (ACL) transection model of PTOA and leveraging an innovative SPiDER-senescence-associated β-galactosidase stain to discern senescent cells, we investigated cellular senescence at single-cell resolution and identified anti-inflammatory macrophages as a predominant contributor to the senescent cell burden in both muscle and knee joint after injury. Clearance of senescent cells using the senolytic dasatinib and quercetin (D + …

Aligned But Disengaged: Self-Estrangement Weakens Citizenship Behavior In Higher Education, Andrew Krouse, Rob E. Carpenter

Human Resource Development Faculty Publications and Presentations

Higher education depends on discretionary employee contributions that sustain coordination, service continuity, and institutional functioning. Yet contemporary governance and accountability pressures can reconfigure higher education work in ways that erode autonomy, line-of-sight, and intrinsic reward, elevating the risk of work alienation, weakening the discretionary behaviors institutions rely on. This study tests whether person–organization fit (POF) predicts organizational citizenship behavior (OCB) and whether multidimensional work alienation mediates this relationship through powerlessness, meaninglessness, and self-estrangement. Using survey data from 325 employees across four U.S. higher education institutions, we applied confirmatory factor analysis and structural equation modeling with bias-corrected bootstrapping. Model comparisons were …

Teen Suicide And The Outcomes Of Surviving Peers, Emily Cuddy, Janet Currie, Elisa Jácome, Lucy Manly

Cowles Foundation Discussion Papers

By age 17, a quarter of U.S. students have experienced a peer suicide. Using linked administrative data from South Carolina and a matched difference-in-differences design, we find that exposure to a peer’s self-harm death increases the probability of a self-harm diagnosis by nearly 50% and both the incidence and frequency of mental health visits. Effects on care use and criminal behavior are concentrated among white boys, and responses diverge by prior mental health history: students without a prior diagnosis increase felony offending rather than care-seeking. Deaths from assault and transportation accidents produce no comparable rise in self-harm, consistent with contagion.

Gridded reference evapotranspiration (ET_o) data are widely used for agricultural water management and remote sensing evapotranspiration (RSET) models, but biases can arise where coarse meteorological inputs fail to capture agricultural microclimates. We investigated biases in the gridMET ET_o product across irrigated agricultural areas of the contiguous United States using ET_o calculated from 793 agricultural weather stations, then used those stations to develop monthly correction surfaces. Results show that gridMET systematically overestimates ET_o by 10–20% at most cropland sites, while pockets of underestimation appear in some arid western regions, primarily due to wind speed bias. Wind …

Shifting Faith Among Indigenous People In Arunachal Pradesh, India: Revisiting Greenfeld's Civilizational Framework, M. Amin Khan

Comparative Civilizations Review

This paper examines changing religious demography in Arunachal Pradesh through Liah Greenfeld's theory of civilization as a self-generating and self-reproducing symbolic reality. Using decadal Census data (1971–2011), it traces the demographic decline of Indigenous/Tribal religions classified under “Other Religions and Persuasions” (ORP) alongside the widespread growth of Christianity and the more limited growth of Hinduism. The analysis argues that these demographic shifts reflect more than religious conversion; they reveal differential capacities for cultural reproduction. Whereas civilizations endowed with codified first principles and enduring institutions sustain continuity across generations, Arunachal Pradesh's largely localized and orally transmitted indigenous traditions have proven less …

A Study Of Phylogenetic Relationships Of Dichanthelium Based On Plastomes, Humera Fatima

Theses

Dichanthelium (Hitchcock & Chase) Gould is a genus in the grass family (Poaceae) with a wide range of morphological diversity, exhibiting significant ecological differences. Despite this, its evolutionary relationships are not fully understood. The ambiguity surrounding the boundaries of lineages and the relationships among species has hindered the systematics of the genus. This study aimed to reconstruct the phylogenetic relationships within Dichanthelium, verify the monophyly of species, and evaluate the strength of the inferred relationships across different analytical frameworks. Molecular sequence data of entire plastomes were examined using both maximum likelihood and Bayesian inference methods to develop phylogenetic hypotheses. Phylogenies …
