Psychological Reactance Theory And Tax Evasion Intentions, Diana Falsetta, Brian C. Spilker Jan 2025

Psychological Reactance Theory And Tax Evasion Intentions, Diana Falsetta, Brian C. Spilker

Faculty Publications

This study experimentally examines how tax administration service inefficiencies in the form of tax return processing delays from paper-filed tax returns indirectly affect taxpayer tax evasion intentions through taxpayers’ psychological reactance to the delay. We further consider whether this indirect effect is different when the taxpayer willingly chooses to paper file their tax return versus when the taxpayer is forced to do so. Consistent with Psychological Reactance Theory (PRT), we find that when taxpayers receive delayed refunds, they experience psychological reactance (e.g., anger and frustration with the tax administration) that increases their tax evasion intentions. Further, we find that the …

An House For The Lord: Solomon's Temple And Temple Worship In Ancient Israel, Dan Belnap Jan 2025

An House For The Lord: Solomon's Temple And Temple Worship In Ancient Israel, Dan Belnap

Faculty Publications

It would not be exaggeration to say that at the center of Old Testament history and theology is covenantal worship and the temple. From the Garden of Eden to the altars constructed by Abraham and the patriarchs, and the portable tabernacle of Moses, the concept of sacred space plays a fundamental role throughout biblical history and in the life of ancient Israel. But during the period of the monarchy, it became possible to construct a permanent house for the Lord. Thus, the construction and dedication of the temple are the primary subject within Solomon’s narrative arc. This chapter explores the …

The Future Performance Implications Of Non-Gaap Motivated Investment, Minkwan Ahn, Theodore E. Christensen, Ryan G. Johnson, Melissa F. Lewis-Western Jan 2025

The Future Performance Implications Of Non-Gaap Motivated Investment, Minkwan Ahn, Theodore E. Christensen, Ryan G. Johnson, Melissa F. Lewis-Western

Faculty Publications

We investigate whether consistent non-GAAP reporting is associated with investment efficiency. Prior research finds a positive association between non-GAAP reporting and investment levels, concluding that it represents overinvestment. We corroborate this positive association, but additional tests are not consistent with the conclusion of inefficient overinvestment. Specifically, we explore the relation between investment and future cash flows as a proxy for the realization of investments in positive net present value projects. We find that the investments of firms that consistently report non-GAAP metrics are associated with similar or higher future cash flows than the investments of firms reporting only GAAP earnings, …

Speech-Aided Facial Video Super Resolution With Accurate Lip Motion And Enhanced Frequency Details, Shailza Sharma, Vivek Singh, Abhinav Dhall, Vinay Kumar

School of Engineering, Computing and Mathematics

Despite recent breakthroughs in face hallucination, video face hallucination remains a challenging task due to the issue of consistency across video frames. The temporal dimension in videos makes it difficult to learn facial motion and maintain color uniformity throughout the sequence. To address these challenges, we propose a novel audio-visual cross-modality support based video face hallucination network. The framework excels in learning fine spatiotemporal motion patterns by leveraging the correlation between movement of the facial structure and associated speech signal. Another significant challenge generic to face hallucination is blurriness around the key facial regions, such as mouth and lips. These …

Predictive Perception In Autism, Robert Harlow Jan 2025

Predictive Perception In Autism, Robert Harlow

School of Psychology Theses

This thesis investigates how predictive perception, motor coordination, and neurotype differences influences social perception in autism. It explores how these mechanisms contribute to social difficulties faced by autistic people, through the lens of the double empathy problem and second-person neuroscience.Chapter 2 examined how spoken intentions and visual evidence guide predictive social perception. Across four experiments, results supported a dual-process model whereby top-down expectations shape early perception but are overridden by visual input once motion begins. This led to the ‘kinematic dominance hypothesis’, suggesting motion cues dominate perception once movement begins due to their higher precision.Chapter 3 used high-resolution active motion …
