Private Management Of African Protected Areas Improves Wildlife And Tourism Outcomes But With Security Concerns In Conflict Regions, Sean Denny, Gabriel Englander, Patrick Hunnicutt

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Protected areas can conserve wildlife and benefit people when managed effectively. African governments increasingly delegate the management of protected areas to private, nongovernmental organizations, hoping that private organizations’ significant resources and technical capacities actualize protected areas’ potential. Does private sector management improve outcomes compared to a counterfactual of government management? We leverage the transfer of management authority from governments to African Parks (AP)—the largest private manager of protected areas in Africa—to show that private management significantly improves wildlife outcomes via reduced elephant poaching and increased bird abundances. Our results also suggest that AP’s management augments tourism, while the effect on …

Yearly Population Data At Census Tract Level Revealed That More People Are Now Living In Highly Fire-Prone Zones In California, Usa, Slade Lazeweski, Shenyue Jia, Jessica E. Viner, Wesley Ho, Brian Hoover, Seung Hee Kim, Menas C. Kafatos

Institute for ECHO Articles and Research

In California (CA), the wildland-urban interface (WUI) faces escalating challenges due to surging population and real estate development. This study evaluates communities along CA's WUI that have witnessed substantial population growth from 2010 to 2021, utilizing demographic data and the 2020 WUI boundaries by the University of Wisconsin-Madison SILVIS Lab. Employing the Mann-Kendall test, we analyze yearly population trends for each census tract along the CA WUI and assess their significance. House ownership, affordability, and wildfire risk are examined as potential drivers of this demographic shift. Our findings indicate that 12.7% of CA's total population now resides in census tracts …

Childhood Unpredictability Is Associated With Increased Risk For Long- And Short-Term Depression And Anhedonia Symptoms Following Combat Deployment, Christopher Hunt, Meghan Vinograd, Laura M. Glynn, Elysia Poggi Davis, Tallie Z. Baram, Hal S. Stern, Caroline M. Nievergelt, Bruna Cuccurazzu, Cindy Napan, Dylan Delmar, Dewleen G. Baker, Victoria B. Risbrough

Psychology Faculty Articles and Research

High unpredictability has emerged as a dimension of early-life adversity that may contribute to a host of deleterious consequences later in life. Early-life unpredictability affects development of limbic and reward circuits in both rodents and humans, with a potential to increase sensitivity to stressors and mood symptoms later in life. Here, we examined the extent to which unpredictability during childhood was associated with changes in mood symptoms (anhedonia and general depression) after two adult life stressors, combat deployment and civilian reintegration, which were assessed ten years apart. We also examined how perceived stress and social support mediated and /or moderated …

The Truth About Partisan Affiliation: Fear, Trust, And Media, Hailey Merin

Student Scholar Symposium Abstracts and Posters

As the father of Western logic, Aristotle's research of the scientific method of analysis, biology, and psychology has been adopted by present-day America. If America has openly accepted an array of Aristotle's teachings, why have they ignored his observations that political parties are non-Democratic?

This research explores the relationship between political party affiliation, sentiment toward the government, and media influence on fear of corrupt government officials. Firstly, this paper examines the idea that sentiments toward the government are influenced by partisan affiliation. Secondly, it determines that after the 2020 election, Republicans fear corrupt government officials more than any other major …

The Pride Pipeline: Violent Nationalism In The United States, Emily Veloz

Student Scholar Symposium Abstracts and Posters

A striking rise in American Nationalism has emerged due to varying factors; however, a particular selection of identities have acted as primary contributors to this phenomenon. This piece navigates the increasing application of violence in the political arena in tandem with the impacts of racial, socioeconomic, and social factors that have fueled this collective aggression. Previous research points toward the hyperpolarization that has been perpetuated by political figures and media outlets, the augmentation of a psychological us-vs.-them mentality, and the perceived threat to American hegemony across the globe. Through an analysis of data provided by the 9th edition of the …

Student Scholar Symposium Abstracts and Posters

Active duty military members can be subjected to significant amounts of stress, trauma, and physical and mental exhaustion during their service periods. It is vital to recognize the extent of these mental health disorders because they affect 27% of veterans, and when not adequately treated, they can lead to increased functional disability, even more so than physical illnesses (Philips, 2016; Wells et al., 1989). This study aims to examine how different types of information influence the perceptions of therapy for veterans. Veterans of all branches of the United States military between the ages of 18 and 100 were asked to …

Climate Change Skepticism: Who And Why?, Mia Huyen Truong

Student Scholar Symposium Abstracts and Posters

Despite persistent scientific consensus urging immediate action, political polarization, and skepticism have hindered effective climate change mitigation, especially in the United States. This paper explores the factors influencing climate change attitudes among different groups, focusing on right-wing affiliates and Christian believers. Drawing on the Anti-Reflexivity Thesis (McCright and Dunlap, 2001-2010) and Information Processing Theory (Wood & Vedlitz, 2007), we investigate the effects of individual characteristics, including partisan ideology, party identification, educational attainment, and Christian faith. Using Wave 7 (2021) of the Chapman Survey of American Fears Survey, a nationwide sample of different fears among U.S. adults, this study aims to …

Pharmacy Faculty Articles and Research

The COVID-19 pandemic has caused enormous societal upheaval globally. In the US, beyond the devastating toll on life and health, it triggered an economic shock unseen since the great depression and laid bare preexisting societal inequities. The full impacts of these personal, social, economic, and public-health challenges will not be known for years. To minimize societal costs and ensure future preparedness, it is critical to record the psychological and social experiences of individuals during such periods of high societal volatility. Here, we introduce, describe, and assess the COVID-Dynamic dataset, a within-participant longitudinal study conducted from April 2020 through January 2021, …

Equivalent Hazard Magnitude Scale, Yi Victor Wang, Antonia Sebastian

Institute for ECHO Articles and Research

Hazard magnitude scales are widely adopted to facilitate communication regarding hazard events and the corresponding decision making for emergency management. A hazard magnitude scale measures the strength of a hazard event considering the natural forcing phenomena and the severity of the event with respect to average entities at risk. However, existing hazard magnitude scales cannot be easily adapted for comparative analysis across different hazard types. Here, we propose an equivalent hazard magnitude scale to measure the hazard strength of an event across multiple types of hazards. We name the scale the Gardoni Scale after Professor Paolo Gardoni. We design the …

Crisisready's Novel Framework For Transdisciplinary Translation: Case-Studies In Wildfire And Hurricane Response, Andrew Schroeder, Caleb Dresser, Akash Yadav, Jennifer Chan, Shenyue Jia, Caroline Buckee, Satchit Balsari

Institute for ECHO Articles and Research

Extreme weather events including wildfires and hurricanes are becoming increasingly hazardous due to climate change, and often result in transient or permanent population displacements. Disaster-related disruptions in infrastructure, workforce, wages, and social networks can combine with population displacements to result in interruptions in health care access and prolonged impacts on morbidity and mortality. The data needed to make health systems and emergency management approaches more resilient to these hazards, and more responsive to the needs of affected populations, are sequestered in silos across private corporations and public agencies. In two case studies, we describe how our research team at CrisisReady …

The Levels And Discrepancies Of America’S Fear Of Terrorism, Kate Lindfors

Student Scholar Symposium Abstracts and Posters

Within the United States, individuals do not appear to possess an accurate understanding of terrorism and the threat it may pose to Americans. This not only creates inaccurate perceptions of the actual risk levels associated with terrorism in the U.S. but a misunderstanding of the potential sources of terrorist threats and the impact they could have on the country. In this paper, I will examine this misunderstanding of contemporary terrorism, particularly in relation to America’s inflated sense of fear and general misplacement of the threat. In order to examine this topic, I have used the Chapman University Survey on American …

Hybrid U-Net: Semantic Segmentation Of High-Resolution Satellite Images To Detect War Destruction, Shima Nabiee, Matthew Harding, Jonathan Hersh, Nader Bagherzadeh

Economics Faculty Articles and Research

Destruction caused by violent conflicts play a big role in understanding the dynamics and consequences of conflicts, which is now the focus of a large body of ongoing literature in economics and political science. However, existing data on conflict largely come from news or eyewitness reports, which makes it incomplete, potentially unreliable, and biased for ongoing conflicts. Using satellite images and deep learning techniques, we can automatically extract objective information on violent events. To automate this process, we created a dataset of high-resolution satellite images of Syria and manually annotated the destroyed areas pixel-wise. Then, we used this dataset to …

If A Tree Falls In The Forest: Presidential Press Conferences And Early Media Narratives About The Covid-19 Crisis, Masha Krupenkin, Kai Zhu, Dylan Walker, David Rothschild

Business Faculty Articles and Research

Throughout the COVID-19 crisis, as we confronted questions about social distancing, masking wearing, and vaccines, public safety experts warned that the consequences of a misinformed population would be particularly dire due to the serious nature of the threat and necessity of severe collective action to keep the population safe. Thus, the media and the political elites (e.g., President of the United States) who possess the power to set the information agenda around COVID-19 bear a huge responsibility for the general welfare. Through automated text analysis of complete transcripts of national cable, network, and local news, we explore their narratives surrounding …

Covid 19 & Qanon: Enter The World Of Conspiracies, Gianluca Allesina

Student Scholar Symposium Abstracts and Posters

From Covid-19 to Qanon to a global warming hoax, we live in a world drowning in misinformation spread on the internet. Q-anonymous, a purposed government “leaker” is an alleged high-level government informant, according to Qanon followers, who posted cryptic messages about a satanic government on the now-defunct forum website, 8chan. This project will examine the possible relationship between a belief in various conspiracy theories associated with Qanon and how the Coronavirus affected rates of belief, utilizing the Chapman Survey of American Fears, a national study using a representative sample of U.S. adults. I expect to find that partisanship will play …

Friend Or Foe: Explaining The Antagonism Towards Immigrants In The United States, Skyelar Andrews

Student Scholar Symposium Abstracts and Posters

Following the 2016 election in which immigration became a leading political issue, fear of immigrants has fueled greater divides amongst the American citizenry. Building off group threat theory, I examine the extent that party affiliation, age, income, and geography impact one’s fear of immigrants. Utilizing the Chapman Survey of Fears from 2016, 2018, and 2021, an online nationwide survey conducted with a representative national sample of US adults, I expect to find an increase in fear of immigrants in all independent variables as time passes from 2016 to 2021, paralleling immigration’s rise to the national stage during the 2016 election. …

Monitoring War Destruction From Space Using Machine Learning, Hannes Mueller, Andre Groeger, Jonathan Hersh, Andrea Matranga, Joan Serrat

Economics Faculty Articles and Research

Satellite imagery is becoming ubiquitous. Research has demonstrated that artificial intelligence applied to satellite imagery holds promise for automated detection of war-related building destruction. While these results are promising, monitoring in real-world applications requires high precision, especially when destruction is sparse and detecting destroyed buildings is equivalent to looking for a needle in a haystack. We demonstrate that exploiting the persistent nature of building destruction can substantially improve the training of automated destruction monitoring. We also propose an additional machine-learning stage that leverages images of surrounding areas and multiple successive images of the same area, which further improves detection significantly. …

Beyond The Politics Of Climate Change: How Education And Income Level Affect Environmental Values, Joanna Falla

Student Scholar Symposium Abstracts and Posters

Human-caused climate change has been acknowledged for decades, but public opinion on its validity and severity has been consistently questioned in the United States. Despite the overwhelming evidence pointing towards fossil fuel emissions and unsustainable practices as the leading causes of global climate change, its politicization during the beginning of the century has seriously slowed down America’s path towards a green future. Because this has become a partisan issue for many voters, considerable research has been done on the affiliation between party identification and public opinion on climate change. Although party identification has been studied as a major factor, other …

Effect Of Free Trade Agreements On Pharmaceutical Market Competition: The Case Of The 2009 Us-Peru Free Trade Agreement And Its Implementation As National Drug Policy, Lita Araujo, Enrique Seoane-Vazquez, Michael Montagne

Pharmacy Faculty Articles and Research

Free Trade Agreements (FTA) are controversial for threatening essential aspects of health, especially access to affordable medicines. The US-Peru FTA required changes in the Peruvian pharmaceutical legislation that resulted in the implementation of the National Drug Policy (NDP) of 2009. The NDP included more robust technical requirements for registration, a Peruvian Good Manufacturing Practices certificate, a longer timeline for drug registration, and an increase in registration fees. This study evaluated the impact of the FTA on the number of registrations and competition in the Peruvian pharmaceutical market.

Should The State Of Israel Pursue Krav Maga As An Intangible Cultural Heritage Of The Jewish People? History And Politics Say Yes., Guy Mor, Andrea Molle

Political Science Faculty Articles and Research

Krav Maga (‘contact combat’) is an Israeli combat discipline arguably one of the many intangible cultural heritages of Israel and the Jewish people. It has played a unique role in the (re)creation and preservation of the Jewish identity and the formation of the state of Israel.

Recently we observe a growing academic literature debating the role of martial arts in international affairs and domestic political processes. It is the scope of this paper to contribute to this proposing a framework for understanding Krav-Maga as a means of cultural diplomacy as seen in other nations.
