IMPORTANCE: While much of the focus on long COVID (LC; defined as developing new, persistent symptoms lasting 3 months or longer after SARS-CoV-2 infection) has been on health status and quality of life, the impact on individual work productivity and financial distress are less well established.

OBJECTIVES: To assess differences in work and financial outcomes among individuals with current, resolved, and no LC up to 3 years after initial infection.

DESIGN, SETTING, AND PARTICIPANTS: This prospective, multisite, longitudinal cohort study enrolled adult participants (age ≥18 years) with at least 1 reported SARS-CoV-2 infection from December 7, 2020, to August 29, …

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 …

Skilled Migrants' Experiences Of Othering, Alterity And Language Policing, Uma Jogulu, Maggie Mcalinden, Melissa A. Parris, Juliana Mutum

Research outputs 2022 to 2026

The Australian Permanent Migration Program and related settlement services have been critical to Australia's success as a stable, democratic and culturally diverse nation. However, emerging research has revealed that this success may come with a high price for as many as one in four skilled migrants who find themselves employed beneath their level of education, expertise and experience, which we define as underemployment. We designed a study that sought to understand the settlement experiences of 36 Asia-Pacific-skilled migrants working as managers. Incorporating Spivak's concepts of subalternity, othering and alterity as a theoretical framework, our analysis uncovered how migrant identity intersected …

The Generality Of Psychosocial Safety Climate Theory—A Fundamental Element For Global Worker Well-Being: Evidence From Four Nations, May Young Loh, Michelle Chin Chin Lee, Maureen Dollard, Dianne Gardner, Kazuki Kikunaga, Tsukumi Tondokoro, Akinori Nakata, Mohd Awang Idris, Tim Bentley, Ali Afsharian, David Tappin, Darryl Forsyth

Research outputs 2022 to 2026

Occupational health and safety researchers and policymakers often rely on organisational theories and evidence to provide valuable information for effective policy making and understanding. Yet, most traditional and contemporary organisational theories are developed within a single nation, often in high-income countries. Therefore, cross-national validation is required for generalisable worldwide use. The current study focuses on an antecedent to workplace health and safety, that is, the psychosocial safety climate (PSC), and aims to investigate if PSC is an etic (i.e., universally applicable) or emic (i.e., nationally/context specific) theory. Across nations, we investigate the construct meaning of PSC by testing PSC measurement …

Exercise Perceptions In People With Metabolic Dysfunction-Associated Steatotic Liver Disease: Insights From A Qualitative Study, Kedar Deshpande, John Olynyk, Oyekoya Ayonrinde, Kazunori Nosaka

Research outputs 2022 to 2026

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a chronic liver condition associated with lifestyle and metabolic risk factors. While exercise is a beneficial treatment strategy, many patients struggle to implement and perform exercise regularly. It is important for practitioners to know about patient awareness, attitudes, and preferences regarding exercise in the con-text of MASLD. In this study, we examined exercise knowledge, attitudes, and exercise preferences among patients with MASLD to improve their exercise behavior changes. Methods: We conducted a questionnaire and semi-structured inter-view study in adults with MASLD to assess their disease awareness, perspectives on exercise and exercise preferences. …

Ocular Changes As Potential Biomarkers For Early Diagnosis Of Alzheimer's Disease, Purna Chandra Poudel, Shaun M. Frost, Shaun Eslick, Hamid R. Sohrabi, Kevin Taddei, Eugene Hone, Ralph N. Martins

Research outputs 2022 to 2026

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. AD diagnosis often involves a thorough assessment, including clinical evaluation, cognitive testing, medical history examination, genetic testing, and biomarker analysis. Currently, the invasive nature and high costs of biomarker testing, such as cerebrospinal fluid analysis and neuroimaging, have limited the early detection and intervention of the disease. Therefore, researchers have explored cheaper and less invasive options, such as ocular imaging. This review discusses the close relationship between the eye and the central nervous system and ocular changes as a potential non-invasive AD biomarker. Ocular changes …

Restricting Outdoor Advertising Of Unhealthy Food: Can Australia's Food Category-Based Classification System Be Applied Consistently?, Clare Whitton, Frith Klug, Alexia Bivoltsis, Georgina S.A. Trapp, Claire E. Pulker

Research outputs 2022 to 2026

Most outdoor food advertising (e.g. billboards and bus stops) features foods that are considered unhealthy. The most important technical challenge when designing policies to restrict unhealthy outdoor food advertising is defining 'unhealthy food'. To date, most restriction policies have used nutrient profiling models (i.e. foods are classified according to their nutritional composition) to determine which foods and beverages may be advertised. In Australia, state governments have endorsed a food category-based classification system, with no prescribed nutrient limits, which may create ambiguity when multiple users are identifying food advertisements to be restricted. This study aimed to assess the consistency of decisions …

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 …

Pseudo-Soft-Switching Switched-Capacitor Drive Circuits For Small-Scale Dielectric Actuators, Yanqiao Li

Dartmouth College Ph.D Dissertations

Applications including micro-robotics and haptics have motivated extensive exploration of dielectric actuators due to their high bandwidth and high efficiency at cm and mm scales. To maximize their benefits, dielectric actuators, including piezoelectric and electrostatic actuators, typically require high driving voltages, ranging from 100V to several kV. Generating such high driving voltages presents a challenge for drive circuits, particularly when powered by a small battery. Dielectric actuators are predominantly capacitive in most circumstances, necessitating the drive circuits to deliver and recover reactive energy for efficient operation. In some applications, such as micro-robotics, the drive circuits may need to have a …

The purpose of this study is to explore the social actions taken by organizational leaders in the pursuit of activism. In recent years, corporate leaders, namely CEOs, have garnered substantial public notice due to their activism and personal rhetoric around social issues, therefore attracting attention within organizational scholarship and practice. By applying the theoretical frameworks of framing, this study conducted a content analysis of activism statements (N = 199) from CEOs of Fortune 500 companies using a mixed-methods approach involving manual coding and computational methods (NVivo). By doing so, this study advances CEO activism communication research by identifying dominant …

Standard Cardiovascular Risk Prediction Scores Underestimate Risk In Immune-Mediated Thrombotic Thrombocytopenic Purpura Survivors, Vijay Nambi, Ang Li, Shruti Chaturvedi, Senthil Sukumar

Faculty, Staff and Students Publications

Background: Immune-mediated thrombotic thrombocytopenic purpura (iTTP) is a rare hematologic disorder with improved survival due to advancements in treatment. However, long-term cardiovascular morbidity and mortality remain significant. Established cardiovascular risk calculators, such as the 2008 Framingham Heart Study (FHS) global cardiovascular disease (CVD) and the American College of Cardiology/American Heart Association (ACC/AHA) atherosclerotic CVD (ASCVD) risk estimators, may not adequately account for the elevated and unique cardiovascular risks in iTTP survivors.

Objectives: To evaluate the discrimination and calibration of the ACC/AHA ASCVD and FHS global CVD models in predicting major adverse cardiovascular events (MACEs) among iTTP survivors.

Methods: This retrospective …

Changes In Post-Transplant Serum Testosterone Levels In Men Undergoing Lung Transplantation: A Pilot Study Using The Trinetx Research Network, Erin Jesse, Mohit Khera, Kenneth Chavin, Nannan Thirumavalavan

Faculty, Staff and Students Publications

Hypogonadism is understudied in men requiring solid organ transplants, particularly among lung transplant recipients. Improvement in serum testosterone levels has been reported in kidney and liver transplantation. Using the TriNetX Research Network, we performed a retrospective cohort study to evaluate the incidence of peri-transplant hypogonadism and the natural course of serum testosterone following successful lung transplantation. Men aged ≥ 18 with a lung transplant and total testosterone drawn within one year pre- and post-transplant were included. Men with receipt of testosterone therapy were excluded. A low testosterone (< 300 ng/dL) and normal testosterone (≥300 ng/dL) cohort was created before employing descriptive and analytic statistics to investigate the incidence of peri-transplant hypogonadism and the change in serum testosterone levels following lung transplantation. In our entire cohort, lung transplantation was not associated with a significant increase in post-transplant serum testosterone (329.86 ± 162.56 ng/dL pre-transplant and 355.13 ± 216.11 ng/dL post-transplant, p = 0.483). The number of men with low testosterone decreased by 9.8% following lung transplantation but was not significant, p = 0.404. In this pilot study, no significant change in the number of hypogonadal men nor serum testosterone levels was observed among men undergoing lung transplantation.

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 …

Biomarkers Of Cellular Senescence In Type 2 Diabetes Mellitus, Thomas A White, Elizabeth J Atkinson, Amanda Tweed, Allyson K Palmer, Nathan K Lebrasseur, Jad G Sfeir, Sundeep Khosla

Faculty, Staff and Students Publications

Although animal studies have linked cellular senescence to the pathogenesis and complications of type 2 diabetes mellitus (T2DM), there is a paucity of corroborating data in humans. Thus, we measured a previously validated marker for senescent cell burden in humans, T‐cell expression of p16 mRNA, along with additional biomarkers, to compare the senescence phenotypes of postmenopausal control (lean, N = 37) and T2DM (N = 27) participants. To control for effects of obesity alone, we included a third group of obese but non‐diabetic women (N = 29) who were matched for body mass index to the T2DM participants. …

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 …

Issues In Contrasting Conservative And Considered Estimation: A Reply To Bobko Et Al. (2024), Paul R. Sackett, Christopher M. Berry, Filip Lievens, Charlene Zhang

Research Collection Lee Kong Chian School Of Business

Bobko et al. (2024) responded to Sackett et al.'s (2022) compilation of meta-analytic evidence for the validity of a wide variety of measures used as predictors of overall job performance, offering a set of alternative methodological choices which they term “considered estimation” to counter the Sackett et al. approach of “conservative estimation.” Here we offer a rebuttal to Bobko et al. A primary concern is that Bobko et al. apply the label “conservative estimation” to the full range of methodological choices made by Sackett et al. Yet, we clarify the narrow and specific meaning of “conservative estimation,” and note that …

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 …

Psychometric Evaluation Of The Yale-Brown Obsessive-Compulsive Scale In Pregnant Women, Gerald Nestadt, Paul Nestadt, Mary C Kimmel, Tracey Dibbs, Lauren M Osborne, Jack Samuels, Janice Krasnow, Eric A Storch

Faculty, Staff and Students Publications

Purpose: Although many women experience obsessive-compulsive symptoms during the perinatal period, the Yale-Brown Obsessive Compulsive Scale (YBOCS) has not yet been psychometrically evaluated in this population. This study examined the internal consistency, convergent and divergent validity, and factor structure of the YBOCS among pregnant women.

Methods: 256 Women who were 20 to 24 weeks pregnant completed the clinician-administered YBOCS and Mini International Neuropsychiatric Interview (MINI) along with a series of self-report questionnaires including the Edinburgh Postnatal Depression Scale (EPDS), Perinatal Anxiety Screening Scale (PASS) and Obsessive-Compulsive Inventory-Revised (OCI-R).

Results: Internal consistency of the YBOCS was excellent, and there were strong …

Relapse Patterns Among Children And Adolescents With Kaposi Sarcoma In Malawi, William Kamiyango, Jimmy Villiera, Parth S Mehta, Erin Peckham-Gregory, Mark Zobeck, Michael E Scheurer, Carl E Allen, Rizine Mzikamanda, Nmazuo W Ozuah, Nader Kim El-Mallawany

Faculty, Staff and Students Publications

Kaposi Sarcoma (KS) is a common childhood cancer in Malawi, but few studies have exploredclinical characteristicsofrelapsed disease. We aimed to characterize clinical patterns of relapse to improve treatment and, ultimately, long-term survival in patients with pediatric KS.A retrospective cohort study was conducted among patients ages < 19 years of age at time of KS diagnosis in Lilongwe, Malawi between August 1, 2010 and March 15, 2020. Specifically, emphasis was placed on patients who had relapsed disease and excluded patients with refractory disease or those who died whilst receiving front-line treatment. Salvage therapy typically involved an intensified chemotherapy regimen compared to front-line therapy—namely nonliposomaldoxorubicin plus bleomycin/vincristine or paclitaxel monotherapy.One-hundred and ninety patients with pediatric KS were included in this analysis, 50 of whom experienced relapse (26%).Older median age was associated with occurrence of relapse (10 vs 6.7 years, p-value = 0.004). Median time from diagnosis to first relapse was 10.6 months (range 2.3–49 months). Three-year post-relapse overall survival (OS) for the entire cohort was 60% with a median follow-up time of 4.7 years after relapse.Survival was significantly higher for patients who relapsed with the woody edema clinical phenotype of pediatric KS versus those with visceral/disseminated disease—3-year OS 79% (95% CI 62–100) versus 29% (14–61).These data demonstrate potential for continued survival after KS relapse in the pediatric population and identify subsets of high-risk patients. The higher mortality observed in patients with visceral/disseminated KS highlights the need for improved therapeutic strategies.

Fold-And-Fuse Neurulation In Zebrafish Requires Vangl2

Faculty, Staff and Students Publications

Shaping of the future brain and spinal cord during neurulation is an essential component of early vertebrate development. In amniote embryos, primary neurulation occurs through a "fold-and-fuse" mechanism by which the edges of the neural plate fuse into the hollow neural tube. Failure of neural fold fusion results in neural tube defects (NTDs), which are among the most devastating and common congenital anomalies worldwide. Unlike amniotes, the zebrafish neural tube develops largely via formation of a solid neural keel that later cavitates to form a midline lumen. Although many aspects of primary neurulation are conserved in zebrafish, including neural fold …
