Decomposing Differences In Coronavirus Disease 2019-Related Case-Fatality Rates Across Seventeen Nations, Ashley Wendell Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

As of 1 November 2020, estimated case-fatality rates associated with coronavirus disease 2019 are not uniformly patterned across the world and differ substantially in magnitude. Given the global spatial heterogeneity in case-fatality rates, we applied the Blinder-Oaxaca regression decomposition technique to identify how putative sociodemographic, structural, and environmental sources influence variation in case-fatality rates. We show that compositional and associational differences in country-level risk factors explain a substantial proportion of the coronavirus disease 2019-related case-fatality rate gap across nations. Asian countries fair better vis-à-vis case-fatality rate differences mainly due to variation in returns to sociodemographic, structural, and environmental sources among …

The Conservatism Principle And Asymmetric Preferences Over Reporting Errors, Jivas Chakravarthy, Timothy W. Shields

ESI Working Papers

At present, accounting conservatism is generally viewed from a measurement or reporting perspective. In contrast, we consider whether it relates to a moral rule of conduct. Conservatism has been described as deriving from a preference for reporting errors to be in the direction of understatement rather than overstatement. We experimentally pair Reporters who provide information with Users who rely on the information. We posit that under misaligned incentives that motivate aggressive reporting, Users view an aggressive report as reflecting Reporters’ exploitative intent and expect that a social norm prohibiting aggressive reporting applies. We predict that Users use noisy reporting errors …

A Capital Asset Pricing Model With Idiosyncratic Risk And The Sources Of The Beta Anomaly, Mark Schneider, Manuel A. Nunez

ESI Working Papers

We introduce a generalization of the classical capital asset pricing model in which market uncertainty, market sentiment, and forms of idiosyncratic volatility and idiosyncratic skewness are priced in equilibrium. We derive two versions of the model, one based on a representative agent who cares about three criteria (risk, robustness, and expected returns), and the other with a microfoundation based on three types of investors (speculators, hedgers, and arbitrageurs). We apply the resulting capital asset pricing model with idiosyncratic risk (IR-CAPM) to provide a new theoretical account of the beta anomaly, one of the most fundamental and widely studied empirical limitations …

Financial Reporting And Moral Sentiments, Radhika Lunawat, Timothy W. Shields, Gregory B. Waymire

ESI Working Papers

Dating back at least to Adam Smith (1790), philosophers and researchers expect that people will behave differently when they know their actions are observable to others. We hypothesize that financial reporting reveals managers’ actions and leads them to take different actions that are better aligned with investor interests. We posit that the reason why is the activation of our internal mental self-evaluation that Smith refers to as an “Impartial Spectator.” We test this hypothesis with an experiment in which we manipulate the availability of a financial report that makes managerial actions transparent. Our evidence shows that financial reporting leads a …

Outdoor Air Pollution Exposure And Inter-Relation Of Global Cognitive Performance And Emotional Distress In Older Women, Andrew J. Petkus, Xinhui Wang, Daniel P. Beavers, Helena C. Chui, Mark A. Espeland, Margaret Gatz, Tara Gruenewald, Joel D. Kaufman, Joann E. Manson, Susan M. Resnick, James D. Stewart, Gregory A. Wellenius, Eric A. Whitsel, Keith Widaman, Diana Younan, Jiu-Chiuan Chen

Psychology Faculty Articles and Research

The interrelationships among long-term ambient air pollution exposure, emotional distress and cognitive decline in older adulthood remain unclear. Long-term exposure may impact cognitive performance and subsequently impact emotional health. Conversely, exposure may initially be associated with emotional distress followed by declines in cognitive performance. Here we tested the inter-relationship between global cognitive ability, emotional distress, and exposure to PM2.5 (particulate matter with aerodynamic diameter 2 (nitrogen dioxide) in 6118 older women (aged 70.6 ± 3.8 years) from the Women’s Health Initiative Memory Study. Annual exposure to PM_2.5 (interquartile range [IQR] = 3.37 μg/m³) and NO₂ (IQR …

Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at …

Keep Calm Or Get Excited? Examining The Effects Of Different Types Of Positive Affect On Responses To Acute Pain, Amanda M. Acevedo, Kate A. Leger, Brooke N. Jenkins, Sarah D. Pressman

Psychology Faculty Articles and Research

Researchers typically assume that all forms of positive affect (PA) are equally beneficial for attenuating the physiological stress response. We tested whether this association is more nuanced by examining the role of arousal level of PA on physiological responses to acute pain. Participants (N = 283, 75.6% female, M_age = 20.6) were randomized to a low, mid, or high arousal (calm, happy, and excited, respectively) induction condition or to a neutral control and then completed an acute pain-inducing cold pressor task. Sympathetic and parasympathetic responses along with self-reported pain and distress were assessed. Results indicated that the calm condition …

Quantitative Description Of The Pastoral Economy Of Western Tuvan Nomads, Paul L. Hooper

ESI Publications

Nomadic pastoralism persists at a substantial scale in Tuva and neighboring regions of Inner Asia. Tuvan pastoral lifeways reflect adaptations to both local environments and current economic realities. Much of our quantitative understanding of the economics of Tuvan nomads is derived from data collected in the first half of the 20th century. Accordingly, this paper provides an updated picture of the inner workings of nomadic households using data collected in Barun-Khemchik and Bai-Taiga provinces in 2013–2015. It analyzes herd composition and size, and compares the frequency of different animals kept today with values recorded in Tuva in 1916 and 1931. …

An Assessment Of The Hydrological Trends Using Synergistic Approaches Of Remote Sensing And Model Evaluations Over Global Arid And Semi-Arid Regions, Wenzhao Li, Hesham El-Askary, Rejoice Thomas, Surya Prakash Tiwari, Karuppasamy Manikandan, Thomas Piechota, Daniele Struppa

Mathematics, Physics, and Computer Science Faculty Articles and Research

Drylands cover about 40% of the world’s land area and support two billion people, most of them living in developing countries that are at risk due to land degradation. Over the last few decades, there has been warming, with an escalation of drought and rapid population growth. This will further intensify the risk of desertification, which will seriously affect the local ecological environment, food security and people’s lives. The goal of this research is to analyze the hydrological and land cover characteristics and variability over global arid and semi-arid regions over the last decade (2010–2019) using an integrative approach of …

Transnational Privilege During The Climate Crisis, Joanna Falla

Student Scholar Symposium Abstracts and Posters

The idea of man-made climate change has been common knowledge in America for decades, yet there is still a significant number of people who are stead-fast climate deniers, regardless of scientific understanding. Past research has covered possible factors in one’s upbringing to cause climate change denials, such as political parties or religion. We seek to answer the curiosity of climate change denial with a much simpler variable: location. The Earth is covered in a myriad of ecosystems, each with its own regional climate. People live across the globe, so each has different values and principles about the environment based on …

Smart Homes For Smart Health: Developing An Interactive System To Reduce In-Home Secondhand Smoke, Christie Kika, Janice Han, Vincent Berardi

Student Scholar Symposium Abstracts and Posters

Smoke from any source is potentially harmful because it contains fine particulate matter that is associated with acute and chronic conditions. Second-hand smoke (SHS) is particularly unsafe for children due to biological characteristics (higher breathing rates, immature lungs and underdeveloped immune systems) that make it difficult to filter toxins.To address this concern, we recently completed Project Fresh Air (PFA), an NIH-funded R01 intervention that installed air particle sensors in the households of tobacco smokers who lived with children. The purpose of our research is to investigate and develop efficient smart home devices that monitor SHS in various living spaces to …

Mulan: An Exploration Of Culture And Representation In Hollywood, Annie Okuhara, Bernadine Cortina, Hung Le, Ryan Nakahara, Jerry Zou

Student Scholar Symposium Abstracts and Posters

'Mulan: An Exploration of Culture and Representation in Hollywood' is a presentation and detailed analysis of various representational, cultural, and minority-related issues in the context of Hollywood and western media. The presentation will focalize specifically around the recent live-action remake of the 1998 film "Mulan". The remake, premiered in March 2020, received critical backlash from various audiences (mostly from the BIPOC community), bashing the film for its misrepresentation of Ancient China and Ancient Chinese culture. Through this misrepresentation, the Hollywood film ultimately reflects views of cultural appropriation, misogyny, and overall minority underrepresentation in the United States. The research presents the …

Pupillometric Investigation Of Spontaneous Action And Intention Awareness, Kate M. Harder, Ruby Moss, Jake Gavenas

Student Scholar Symposium Abstracts and Posters

The neuroscience of volition, to a large extent, investigates the neural precursors of conscious decision-making and action. Pupillometry is a powerful tool for investigating conscious and attentional processing, partly because of its connection to the locus coeruleus (Josh et al., 2016). For instance, in an attentional blink paradigm, differences in pupil dilations were associated with conscious versus nonconscious stimuli (Wierda et al., 2012). Nevertheless, this technique received little attention in the study of volition.

We collected pupil data during a spontaneous action paradigm, where subjects freely pressed a button at a time of their choosing, sometimes reporting their onset of …

Spatial Frequency Implications For Global And Local Processing In Autistic Children, Riya Mody, Ayra Tusneem, Louanne Boyd, Vincent Berardi

Student Scholar Symposium Abstracts and Posters

Visual processing in humans is done by integrating and updating multiple streams of global and local sensory input. Interaction between these two systems can be disrupted in individuals with ASD and other learning disabilities. When this integration is not done smoothly, it becomes difficult to see the “big picture”, which has been found to have implications on emotion recognition, social skills, and conversation skills. An example of this phenomenon is local interference, which is when local details are prioritized over the global features. Previous research in this field has aimed to decrease local interference by developing and evaluating a filter …

#Metoo: Why Twitter Doesn't Do Enough, Tara Mann

Student Scholar Symposium Abstracts and Posters

In 2017 actress Alyssa Milano sparked the #MeToo movement as most people know it today. Unbeknownst to many, however, a black woman named Tarana Burke began the Me Too movement a decade earlier after working with survivors of sexual assault. As more and more injustice through discrimination comes to light, it is important to recognize privilege where it exists and what it allows to happen. This project is an analysis of the rhetoric of the #MeToo movement that aims to prove that this privilege is the problem with the movement. I intend to demonstrate how the use of Twitter to …

Exploring Optimism And Purpose In Life As Mediators Of The Association Between Childhood Socioeconomic Status And Common Cold Susceptibility, Stephanie Munduruca, Vivian Luong, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

According to the U.S. National Library of Medicine, Americans suffer from 1 billion colds a year. Correspondingly, previous research has shown that lower socioeconomic status (SES) during childhood is associated with lower adult health, including decreased resistance to the common cold. This correlation between childhood SES and common cold susceptibility may be mediated by an individual's optimism and purpose in life. Of interest, several studies have found evidence that higher childhood SES is associated with a higher purpose of life and higher optimism. Furthermore, previous evidence has confirmed that higher optimism and higher purpose of life are linked to better …

Child Postoperative Pain: Impact Of Child Temperament And Parent Mood On Pain After Surgery, Harshitha V. Venkatesh, Michelle A. Fortier, Zeev N. Kain, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

Around 80% of children who undergo surgery experience moderate to severe postoperative pain. Various psychosocial factors contribute to exacerbations of this pain. A child’s inborn personality traits and style of interaction with the environment are known as temperament. Children who are less sociable and more distress-prone (e.g., those who cry, throw tantrums) are more likely to have an anxious temperament. This anxiety before and after surgery may lead to an increase in postoperative pain levels as well. Parent pain ratings do not always reflect true child pain. Overtime, a parent’s emotional state and mood may change how they perceive child …

Pediatric Asthma And Psychological Resilience: Examining Whether Family Functioning And Social Support Relate To Asthma Symptoms And Lung Function, Dalia Jaafar, Natasha H. Hikita, Pornchai Tirakitsoontorn, Azucena Talamantes, Anchalee Yuengsrigul, Eric Sternlicht, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

Upwards of 6 million children in the United States are afflicted with pediatric asthma. While previous research has linked asthma to multiple contributing biological and environmental factors, recent research suggests that psychological and social factors may have an impact on physiological outcomes of asthma like lung function and lung inflammation. Therefore, we suggest the need to study the impact of positive psychological factors such as a well-functioning family environment and beneficial social support on symptoms and lung function of children diagnosed with asthma. In the present pilot study, we recruited a total of 15 children with a confirmed asthma diagnosis …

Fear Of Illegal Immigration, Sofia Sanchez

Student Scholar Symposium Abstracts and Posters

Illegal immigration has continuously been a hot topic, and the American population has obsessed over what measures should be taken with these people, if any. In a qualitative study, the fear of illegal immigration is going to be analyzed based on various independent variables such as ideology, party identification, and media, based on results from the Fear 2020 survey. The Chapman Survey of American Fear began in 2018, analyzing people’s different fears nationwide, and how those might be related to other characteristics. Previous research analyzes attitudes towards illegal immigration; however the fear component will be a new addition to this …

Women's Political Participation Aided By Constitutional Provisions In Post-Conflict African Nations, Roksana Gorgolewski

Student Scholar Symposium Abstracts and Posters

After two major continental conflicts, many African countries were forced to re-evaluate their constitutions and inherent political structures. This left a window of opportunity for greater female political participation as political leaders and members of the peacemaking process. This project will focus on selected African post-conflict states during the 1970’s to 2000’s that have re-written their constitutions. The general query asks whether those rewritten constitutions have contributed to greater gender equality in the legislature of those states and which constitutional provisions work best at promoting and maintaining gender equality. By studying Geisler’s book Women and the remaking of politics in …

Fear Of Whites No Longer Being The Majority, Kassandra Gomez Orozco

Student Scholar Symposium Abstracts and Posters

The 2014 National Projections report was based on the 2010 Census and estimates through 2013. The finding of these studies predict that by 2044, more than half of the American population will belong to a minority. The idea of whites no longer being the majority may be alarming to some people, as it has always been the norm of the country. This perceived threat of demographic change may be an indicator voters voting out of fear, and voting for candidates that cater to that fear. This paper will attempt to look at whether ethnicity or party identification have more relationship …

Failure To Protect: Why The International Community Will Fail To Respond To The Cultural Genocide Of Turkish Cypriot People, Hilmi Ulas

Peace Studies Faculty Articles and Research

The international community has time and again committed to never let genocide occur again – however, multiple bouts of genocide have occurred since the Holocaust. This, in addition to the current quandaries surrounding the Uyghurs of China, points to the fact that the international laws and institutions have loopholes that allow for genocides – especially those that enact structural and cultural violence without necessarily employing direct violence – to ‘slip through’.

This has been the case in spite of R2P policies being in place. In this paper, I examine the inability of international systems to capture ‘cultural genocide’ or intervene …

Shared Service In The Archives: The Johns Hopkins University First-Generation Students Oral History Project, Jennifer Kinniff, Annie Tang

Library Books and Book Chapters

"Archivists, like librarians, often provide service to users that is defined by the mission and the institutional context of their employer. University archivists are tasked with documenting the history of their institution, and in doing so, have historically focused much of their attention on the records of institutional offices. This practice leaves out the stories of students and other communities affected by the institution. As immersed as university archivists are in academic libraries and the infrastructure of the academy, activist archivists can still challenge the status quo through intentional collecting of what is neither de facto, nor traditional. As archivists …

Productivity Loss Associated With Functional Disability In A Contemporary Small-Scale Subsistence Population, Jonathan Stieglitz, Paul L. Hooper, Benjamin C. Trumble, Hillard Kaplan, Michael D. Gurven

ESI Publications

In comparative cross-species perspective, humans experience unique physical impairments with potentially large consequences. Quantifying the burden of impairment in subsistence populations is critical for understanding selection pressures underlying strategies that minimize risk of production deficits. We examine among forager-horticulturalists whether compromised bone strength (indicated by fracture and lower bone mineral density, BMD) is associated with subsistence task cessation. We also estimate the magnitude of productivity losses associated with compromised bone strength. Fracture is associated with cessation of hunting, tree chopping, and walking long distances, but not tool manufacture. Age-specific productivity losses from hunting cessation associated with fracture and lower BMD …

Response To Commentaries On ‘Hard Criteria For Empirical Theories Of Consciousness’, Adrian Doerig, Aaron Schurger, Michael H. Herzog

Psychology Faculty Articles and Research

In consciousness research, we have a very large number of theories, which exceeds by far the number of theories in other fields. We recently presented a set of criteria for evaluating and comparing theories of consciousness, and then applied the criteria to a number of different theories. Our publication sparked strong responses as evident by the many comments published in Cognitive Neuroscience (this issue). Overall, there seems to be consensus that a theory of consciousness (ToC) needs to have an unconscious alternative, but other criteria sparked controversy. The hottest debate is to what extent consciousness needs to work with purely …

Deliberation Enhances The Confirmation Bias In Politics, David L. Dickinson

ESI Publications

The confirmation bias, unlike other decision biases, has been shown both empirically and in theory to be enhanced with deliberation. This suggests that limited attention, reduced deliberation, or limited available cognitive resources may moderate this bias. We aimed to test this hypothesis using a validated confirmation bias task in conjunction with a protocol that randomly assigned individuals to one week of at-home sleep restriction (SR) or well-rested (WR) sleep levels. We also used a measure of cognitive reflection as an additional proxy for deliberation in our analysis. We tested the hypotheses that the confirmation bias would be stronger for WR …

Seroprevalence Of Novel Coronavirus Sars-Cov-2 At A Community Hospital Emergency Department And Outpatient Laboratory In Northern Orange County, California, Jason Yamaki, Harry Peled, Sajen Mathews, David Park, Mina Firoozi, Kim Smith, Lee Nguyen

Pharmacy Faculty Articles and Research

Introduction

The severe acute respiratory syndrome related coronavirus 2 (SARS-CoV-2) has infected more than 20 million people worldwide, and the spread is most prevalent in the USA, where California had accounted over 240,000 cases in the initial 5 months of the pandemic. To estimate the number of infected persons in our community, we conducted a cross-sectional study to estimate seroprevalence of SARS-CoV-2 infection.

Methods

This cross-sectional study evaluated the presence of immunoglobulin G, antibody for SARS-CoV-2 during the time period of July 15, 2020, to July 27, 2020. Testing was done on serum samples from patients who had visited affiliated …

Air Pollution And The Dynamic Association Between Depressive Symptoms And Memory In Oldest-Old Women, Andrew J. Petkus, Diana Younan, Xinhui Wang, Daniel P. Beavers, Mark A. Espeland, Margaret Gatz, Tara Gruenewald, Joel D. Kaufman, Helena C. Chui, Joann E. Manson, Susan M. Resnick, Gregory A. Wellenius, Eric A. Whitsel, Keith Widaman, Jiu-Chiuan Chen

Psychology Faculty Articles and Research

BACKGROUND/OBJECTIVES

Exposure to air pollution may contribute to both increasing depressive symptoms and decreasing episodic memory in older adulthood, but few studies have examined this hypothesis in a longitudinal context. Accordingly, we examined the association between air pollution and changes in depressive symptoms (DS) and episodic memory (EM) and their interrelationship in oldest-old (aged 80 and older) women.

DESIGN

Prospective cohort data from the Women's Health Initiative Memory Study-Epidemiology of Cognitive Health Outcomes.

SETTING

Geographically diverse community-dwelling population.

PARTICIPANTS

A total of 1,583 dementia-free women aged 80 and older.

MEASUREMENTS

Women completed up to six annual memory assessments (latent composite …

When Special Education And Disability Studies Intertwine: Addressing Educational Inequities Through Processes And Programming, Audri Sandoval Gomez, Aja Mckee

Education Faculty Articles and Research

The inception of the Education for All Handicapped Children Act (EAHCA) in 1975 provided hope and the opportunity for equitable educational experiences for individuals with disabilities. Forty-five years later, the United States remains in a deficit-driven, medical model educational system with deeply rooted inequities continuing to segregate students because of their disability. A disability studies in education framework allows for complex components of teaching and programming for students with disabilities to be explored in a practical way that promotes inclusive education for all students. Examining special education practices through a social model of disability with a focus on ability and …
