I See Sick People: Beliefs About Sensory Detection Of Infectious Disease Are Largely Consistent Across Cultures, Joshua M. Ackerman, Theodore Samore, Daniel M. T. Fessler, Norman P. Li, Et Al

Research Collection School of Social Sciences

Identifying cues to contagious disease is critical for effectively tracking and defending against interpersonal infection threats. People hold lay beliefs about the types of sensory information most relevant for identifying whether others are sick with transmissible illnesses. Are these beliefs universal, or do they vary along cultural and ecological dimensions? Participants in 58 countries (N = 19,217) judged how effective, and how likely they were to use, cues involving each of the five major sensory modalities in an imagined social interaction during a flu outbreak. Belief patterns were strongly consistent across countries (sight > audition > touch > smell > taste), suggesting a largely …

Socioeconomic Status Shapes Dyadic Interactions: Examining Behavioral And Physiologic Responses, Jacinth J. X. Tan, Tessa V. West, Wendy B. Mendes

Research Collection School of Social Sciences

With more opportunities for diverse interactions, little is known about how social interactions involving people of different socioeconomic status (SES) may unfold. We investigated social attunement patterns in dyadic interactions involving SES. Unacquainted individuals recruited from the community interacted with similar-or-different-SES partners in the lab (Ndyads = 130). Attunement was assessed throughout the interaction by examining physiological linkage—how much a person’s physiological change is predicted by another’s physiological change, over time. Overall, low-SES participants showed stronger physiological linkage—indicating greater attunement—to partners across SES. Participants also appeared more comfortable when interacting with low-SES partners. There were no SES differences in dominance …

A Lifespan Perspective On Positive Affect Fluctuations On Purpose In Life: Findings From A 9-Year Longitudinal Study, Jonathan L. Chia, Verity Y. Q. Lua, Andree Hartanto

Research Collection School of Social Sciences

Existing research has examined how static or average levels of positive affect (PA) influence purpose in life (PIL), but theoretical work suggests PA fluctuations may also play a role, potentially undermining PIL, especially in older adulthood. To this end, the present study examined the longitudinal association of PA fluctuations on PIL and the moderating role of age among 1,294 midlife and older adults in the United States, over a 9-year period (between 2004 and 2014). Results revealed a conditional effect of PA fluctuations on PIL – particularly among older individuals, and greater PA fluctuations were associated with a poorer sense …

Constraints Without Tears For Consequentialists, Matthew Hammerton

Research Collection School of Social Sciences

Agent-relative consequentialism uses the theoretical framework of consequentialism to capture the constraints favored by deontologists. Christopher Howard has recently argued that agent-relative consequentialism is implausible because it can only capture such constraints at the expense of getting other normative facts incorrect. In this reply, I argue that Howard’s objection to agent-relative consequentialism fails because it rests on faulty intuitions that arise from a misunderstanding of basic structural features of agent-relative consequentialism.

Longitudinal And Bidirectional Relations Between Problematic Social Media Use And Cognitive Failures, K. T. A. Sandeeshwara Kasturiratna, Andree Hartanto

Research Collection School of Social Sciences

With social media becoming increasingly pervasive in our daily lives, there have been heightened concerns that the distractions caused by compulsive and problematic social media use may lead to cognitive failures. While some preliminary work have explored the link between problematic social media use and cognitive functioning, most are cross-sectional, leaving it uncertain whether cognitive failures are a precursor or consequence of problematic social media use. To address this gap, the current study examines the bidirectional relationship between problematic social media use and cognitive failures. A sample of 252 young adults completed the Problematic Social Media Use Scale and the …

Incorporating Ecosystem Service Assessments Into Development Planning − Impact From A Dredging Project In South Australia On Seagrass, Sam Gaylard, Rachel Colella, Matt Nelson, Paul Lavery, Michelle Waycott

Research outputs 2022 to 2026

Major infrastructure development is required for economic development and to improve human well-being, however conflict exists between developers and the community. Environmental impact assessment (EIA) is used in over 100 countries to evaluate potential impacts of major developments across environment, economy, and social benchmarks. However, EIA has been criticized for a lack of transparency and accountability, lack of consultation or participation and inadequate science. An ecosystem service assessment (ESA) recognizes the links between the environment and the socio-economic environment, resulting in a more holistic evaluation of potential impacts and effective community consultation. Despite this, its inclusion within EIA's is rare. …

An Injectable, Dual-Curing Hydrogel For Controlled Bioactive Release In Regenerative Endodontics, Meisam Omidi, Daniela S. Masson-Meyers, Jeffrey M. Toth

Biomedical Engineering Faculty Research and Publications

Regenerative endodontics seeks to restore the vascularized pulp–dentin complex following conventional root canal therapy, yet reliable neovascularization within the constrained root canal remains a key challenge. This study investigates the development of an injectable, dual-curing hydrogel based on methacrylated decellularized amniotic membrane (dAM-MA) and compares its performance to a conventional gelatin methacryloyl (GelMA). The dAM-MA platform was designed for biphasic release, incorporating both free vascular endothelial growth factor (VEGF) for an initial burst and matrix-metalloproteinase-cleavable VEGF conjugates for sustained delivery. The dAM-MA hydrogel achieved shape-fidelity via thermal gelation at 37 °C and possessed tunable stiffness (0.5–7.8 kPa) after visible-light irradiation. …

Anisotropic Object-Based Shifts Of Attention Arise From Unequal Influences Of Visual Field Meridians On Neural Attention Gradients, David H. Hughes, Adam J. Barnas, Adam S. Greenberg

Biomedical Engineering Faculty Research and Publications

Object-based attention prioritizes the processing of information appearing within a selected object. We previously showed an object-based shift direction anisotropy (SDA) whereby horizontal shifts are more efficient than vertical shifts (Barnas AJ, Greenberg AS. Atten Percept Psychophys 78: 1985–1997, 2016; Barnas AJ, Greenberg AS. Vis Cogn 27: 768–791, 2019), an effect modulated by the visual field meridians (Barnas AJ, Greenberg AS. Q J Exp Psychol (Hove) 77: 2516–2532, 2024). Our present aim was to understand how the functional brain mechanisms of attention give rise to the SDA. We hypothesized that the SDA arises from attentional resources being partitioned differently by …

Mathematical Modeling Of Zoonotic Disease Transmission Under The Impact Of Land Use Change, Collin A. Kilmer

Masters Theses and Doctoral Dissertations

Land conversion is occurring worldwide due to a growing population and expanding economy. This process increases the likelihood of pathogen spillover, posing significant economic and public health risks. The objective of this thesis is to model pathogen spillover under the impact of land use change. We develop a zoonotic disease transmission model that describes spillover of Puumala virus from bank voles to humans during land conversion. Our model introduces a land conversion index to capture the dependence of the carrying capacity and the death rate of bank voles on the proportion of converted land. This index is then used to …

Genetic Study Of Von Willebrand Factor Antigen Levels ≤ 50 Iu/Dl Identifies Variants Associated With Increased Risk Of Vwd And Bleeding, Rachel K. Friedman, Adam S. Heath, Jennifer E. Huffman, James T. Baker, Natalie R. Hasbani, Sarah A. Gagliano Taliun, Ming-Huei Chen, Tom Howard, Joanne E. Curran, John Blangero

School of Medicine Publications

Background: von Willebrand disease (VWD) is a common inherited bleeding disorder caused by low levels or activity of circulating von Willebrand factor (VWF). Genetic susceptibility to VWF antigen (VWF:Ag) below normal (≤50 IU/dL) in the general population is underexplored.

Methods: To identify genetic variants influencing VWF:Ag levels ≤50 IU/dL, we performed a genome-wide association study in 926 cases with VWF:Ag levels ≤50 IU/dL and 12,846 controls from 7 studies from the TOPMed program. We then examined whether genome-wide significant findings were also associated with clinical diagnosis of VWD in 5 biobanks with 708 VWD cases and 1,286,069 controls, and with …

Copyright Laundering Through The Ai Ouroboros: Adapting The 'Fruit Of The Poisonous Tree' Doctrine To Recursive Ai Training, Anirban Mukherjee, Hannah H. Chang

Research Collection Lee Kong Chian School Of Business

Copyright enforcement rests on an evidentiary bargain: a plaintiff must show both the defendant's access to the work and substantial similarity in the challenged output. That bargain comes under strain when AI systems are trained through multi-generational pipelines with recursive synthetic data. As each successive model is tuned on the outputs of its predecessors, any copyrighted material absorbed by an early model is further diffused into deeper statistical abstractions. The result is an evidentiary blind spot where overlaps that emerge look coincidental, while the chain of provenance is too attenuated to trace.These conditions are ripe for "copyright laundering"—the use of …

Successful Treatment Of Aspergilloma With Antifungal Alone: A Case Of Conservative Management, Ad Rian Chong, Khai Lip Ng, Nai Chien Huan, Nur Husna Mohd Aminudin, Raja Nor Adilla Raja Rahaizat, Kasuma Mohamed Nordin

Research outputs 2022 to 2026

Pulmonary aspergilloma can cause life-threatening haemoptysis. Surgical resection and/or bronchial artery embolization (BAE) are established treatment modalities, but both can be risky in frail patients with comorbidities. Spontaneous regression of aspergilloma with antifungal agents alone is rare. We report an elderly gentleman with a background history of treated pulmonary tuberculosis, who presented with haemoptysis due to a large left upper lobe aspergilloma. He declined surgery and BAE due to perceived risks. Oral voriconazole and later isavuconazole were prescribed, which led to clinical improvement and significant reduction in the size of the aspergilloma over 6 months. Antifungal agents might be a …

Debunking Myths: Preparing Black Students Who Are Accelerated Learners For Postsecondary Opportunities, Erik M. Hines, Donna Y. Ford, Renae D. Mayes, Tanya J. Middleton, James L. Moore Iii, Desmond Mcglone

Journal of College Access

Black students are the most underrepresented in Gifted and Talented Education (GATE), Advanced Placement (AP), honors, dual enrollment (DE), and other programs for advanced learners (Ford, 2011, 2013; Hines, 2024; Hines, Fletcher et al., 2022). However, accelerated learners, particularly Black students, are usually seen as individuals who understand their educational trajectory, are more likely to know where they plan to attend college, and quickly know their career choice (Smith & Wood, 2020). Accelerated learners are students who are engaged in advanced coursework or programs such as Gifted and Talented Education (GATE), Advanced Placement (AP), honors, dual enrollment (DE). In this …

The Scintillator Surface Detector Of The Pierre Auger Observatory, A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte, K. Almeida Cheminant, A. Almela, B. Fick, K. Nguyen, D. Nitz, Et Al.

Michigan Tech Publications

Data collected so far by the Pierre Auger Observatory have enabled major advances in ultrahigh energy cosmic ray physics and demonstrated that improved determination of masses of primary cosmic-ray particles, preferably on an event-by-event basis, is necessary for understanding their origin and nature. Improvement in primary mass measurements was the main motivation for the upgrade of the Pierre Auger Observatory, called AugerPrime. As part of this upgrade, scintillator detectors are added to the existing water-Cherenkov surface detector stations. By making use of the differences in detector response to the electromagnetic particles and muons between scintillator and water-Cherenkov detectors, the electromagnetic …

Differing Impacts Of Cardiac Implantable Electronic Device Leads On Tricuspid Regurgitation, Sophie A. Leon, Melissa Austin, Nayeem Nasher, Daler Rahimov, Faizaan Siddique, Chitra Parikh, Danial Ahmad, Vakhtang Tchantchaleishvili, Behzad B. Pavri

Division of Cardiology Faculty Papers

BACKGROUND: Placement of cardiac implantable electronic devices (CIED) with leads that traverse the tricuspid valve is thought to contribute to tricuspid regurgitation (TR). However, there are relatively limited data comparing the impact of different CIED lead types on the incidence and progression of TR. This study sought to quantify the change in TR severity following implantation of CIEDs with different lead types.

METHODS: Patient data were collected on individuals with implantable cardioverter defibrillators (ICD), right ventricular-paced pacemakers (RV-PM), and His bundle-paced pacemakers (His-PM) placed by a single provider at a single institution between 2016 and 2019. Patients with extravascular CIED …

Not All Political Ties Are The Same: Firms' Ties To The Government And Pollution, Wen Helena Li, Ilya R. P. Cuypers, Gokhan Ertug, Hari Bapuji, Wei Liu

Research Collection Lee Kong Chian School Of Business

Complementing research on the implications of political ties for firms’ strategic decisions and financial performance, recent studies are increasingly focusing on the environmental consequences of firms’ political connections. We contribute to this stream of work by integrating insights from the literature on political ties and the multifaceted nature of governments to explore how the level of government influences the pollution implications of firms’ political ties. Specifically, we theorize and demonstrate that, in China, firms' achieved political ties with high levels of the government reduce pollution, while such ties with low levels of the government increase it. Furthermore, we examine how …

What Values Best Distinguish The World's Cultures? The Machine Learning-Based Cultural Values Inventory, Abhishek Sheetal, Shilpa Madan, Rui Ling Lee, Krishna Savani

Research Collection Lee Kong Chian School Of Business

Scientists studying culture typically focus on a small number of theoretical constructs, such as individualism–collectivism, when seeking to explain cultural differences in psychological tendencies and behaviors. However, existing theories of culture could have missed out on important constructs that are useful for explaining cross-cultural differences. We used an abductive approach combining prediction and explanation to uncover important cultural values. In the prediction phase, based on 594 attitudes, values, and beliefs included in the World Values Survey, a neural network could classify respondents’ nationalities with 90% accuracy in out-of-sample data. In the explanation phase, a feature importance analysis identified the values …

Is R&D Rivalry Slowing The Growth Of Productive Firms?, Yoshiki Ando, James Bessen, Xiupeng Wang

Research Collection School Of Economics

The reallocation of jobs to more productive firms is a substantial component of aggregate productivity growth, yet job reallocation rates have declined substantially in the United States. This paper explores the hypothesis that greater technological rivalry has exacerbated adjustment costs, slowing reallocation. Using microdata at the US Census and estimates of technological rivalry in firm growth regressions, we find that technological rivalry slows firm responses to productivity shocks. Firms do not expand as rapidly in the face of higher obsolescence risk. Estimating counterfactual firm growth from 1997-2018, we find that growing technological rivalry accounts for most of the decline in …

Guest Editorial: Who’S Special Now?, Michael Maihofer Dds

The Journal of the Michigan Dental Association

This editorial discusses a controversial change in Michigan's dental specialty advertising law, which occurred in 2020. Previously, only state-recognized specialists, undergoing rigorous advanced training, could advertise their specialty status. However, a new rule, resulting from an out-of-court settlement, paradoxically allows general dentists not recognized as specialists to advertise as such without following advertising rules. This change is criticized for undermining public protection and creating unethical, misleading situations where general dentists advertise as pediatric dentists, for instance. The Michigan Dental Association (MDA) is actively working to revert this law by supporting House Bills 4593 and 4594 to ensure only recognized specialists …

The New Professional: Tracking Success: Essential Kpis For Owners And Associates, Amrita Patel Dds

The Journal of the Michigan Dental Association

This article underscores the importance of Key Performance Indicators (KPIs) for data-driven success in modern dental practices. For new practice owners, essential KPIs include production, collections, and overhead ratio to ensure financial stability and operational efficiency. Patient flow metrics, such as new patient numbers and retention rates, are vital for growth. For both owners and associates, case acceptance rate reflects treatment plan conversion, and chair time utilization measures clinical efficiency. Other critical KPIs encompass hygiene production, patient satisfaction scores, online reviews, and accounts receivable aging. Associates can also track personal production and referral patterns for career development.

Staff Matters: Adding Background Checks And Drug Testing To The Hiring Process, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

This article advises dental practices on legally and carefully implementing pre-employment background checks and drug testing. It emphasizes ensuring non-discriminatory practices by consistently applying policies and clearly defining screening criteria. Practices must obtain written applicant authorization and provide notification of Fair Credit Reporting Act (FCRA) rights before conducting checks. When evaluating results, relevance to the job and timing of convictions should be considered, avoiding blanket bans. For drug testing, transparency is key. Given Michigan's recreational marijuana legality, a positive THC test does not automatically indicate impairment, requiring practices to define their approach. Using a reputable third-party provider for both screenings …
