Heterogeneous beliefs, asset prices, and business cycles

We develop a complete-market production economy in which heterogeneous beliefs about productivity growth affect both asset prices and real activity. Firms must hire workers before productivity is realized, so operating leverage increases the exposure of profits to productivity ri...

A CCL21 gene-modified dendritic cell vaccine combined with pembrolizumab in advanced non-small cell lung cancer: a phase I trial

Abstract Immune checkpoint inhibitors (ICIs) have transformed treatment for non-small cell lung cancer (NSCLC), but resistance to these therapies is common. We report here results from a phase I trial combining intratumoral injection of a CCL21-expressing dendritic cell (CCL21-DC...

SEMIINFINITE SHEAVES ON AFFINE FLAG VARIETIES

Abstract We study a category of semiinfinite sheaves on the affine flag variety of a connected reductive algebraic group G , with coefficients in a field k $\Bbbk $ double struck k (of arbitrary characteristic different from that of the base field), generalizing some results of G...

Enhancing Evidence Generation by Linking Randomized Clinical Trials to Real‐World Data: The INVESTED‐Medicare Linkage Study

Real‐world evidence (RWE) derived from real‐world data (RWD) can complement randomized controlled trials (RCTs), yet the validity of RWD relative to RCT data remains insufficiently characterized. We obtained post hoc consent and linked individual participant data from the US‐base...

Azimuthal Anisotropy From Multimode Waveform Modeling Reveals Layering Within the Antarctica Craton

The isotropic structure of the crust and upper mantle under Antarctica has been constrained by many studies. However, the depth dependence of seismic anisotropy, a powerful tool to characterize deformation and flow, is still poorly known. Here, we modeled three-dimensional (3-D)...

Subspace reverse-correlation estimation of receptive fields during free viewing

Abstract Accurately mapping receptive fields under naturalistic viewing requires correcting for distortions introduced by eye movements. Current approaches often rely on parameterized “shifter networks” optimized with Poisson GLMs, but these methods are computationally intensive...

Corporate Tax Cuts, Firm Growth, and Workers' Earnings

We study the effects of the largest corporate income tax cut in U.S. history on firms and workers. To identify causal effects, we use employer-employee matched tax records and event studies comparing similarly sized firms in the same industry that faced divergent tax changes due...

Double robust, flexible adjustment methods for causal inference: An overview and an evaluation

Double robust methods for flexible covariate adjustment in causal inference have proliferated in recent years. Despite their apparent advantages, these methods are rarely used by social scientists. It is also unclear whether these methods actually outperform more traditional meth...

The Default College: How Racialized Messages Impact Black Student Perceptions of HBCUs and PWIs

Abstract This study used interviews with 20 Black graduate and undergraduate students, Critical Race Theory, and Calmore's Racialized Space Framework to investigate how historical and societal racial narratives shape the messages Black students receive about HBCUs and PWIs. It al...

Risk and Protective Factors for Suicidal Ideation and Attempts Among Older Adults in California, 2021–2024 Pooled Cross-Sectional Study

Background/Objectives: Older adults have high rates of suicide, but there is little research on age-specific correlates of suicide. The purpose of this study was to examine risk and protective factors for suicidal ideation and attempts across adult and older adult age groups in a...

Volunteering and resilience in wartime: evidence from two population-based studies in Israel

Abstract Background Resilience is a key factor in coping with and recovering from large-scale traumatic events. Although volunteering has generally been associated with improving or maintaining resilience, evidence from wartime contexts is mixed. This study examined the associati...

Staff Perspectives on Optimising Organisational Responses to Patient‐Initiated Workplace Violence

AIMS: To identify existing and ideal practices for responding to patient-initiated workplace violence in the US Veterans Health Administration. DESIGN: Cross-sectional, descriptive qualitative design. METHODS: Qualitative interviews with staff (n = 31) in eight veteran healthcare...

Parents of youth and young adults with intellectual and developmental disabilities: Barriers experienced during transition

PurposeThe purpose of this study was to explore the experiences of parents of youth and young adults with intellectual and developmental disabilities who have undergone the transition from pediatric to adult healthcare as well as community-based transition and adult-focused servi...

Developmental shifts in eye morphology and visual ecology of banded flower mantis ( Theopropus elegans )

Abstract Compound eyes display high morphological diversity across arthropods, including rare cone-shaped forms whose visual function is puzzling because their unusual shape seems to defy expectations of how eyes sample visual space. Species in which eye shape changes through dev...
