Disinhibition And Bac Estimation As Predictors Of Risky Driving Behavior While Intoxicated, Sarah Heymsfeld

Theses and Dissertations--Psychology

Alcohol-related driving fatalities persist as a public health problem in the United States. Recent studies have begun focusing on driver risk-taking as a factor in DUI occurrences and consequent driving fatalities. Key factors that could contribute to risky intoxicated driving are a lack of self-awareness concerning intoxication levels and consequent risk in addition to alcohol-induced increases in the driver’s impulsivity. Fifty young adult drivers received 0.65 g/kg of alcohol (target BAC = 80 mg/dl) or a placebo in a counterbalanced order on two different days and performed a simulated driving test that measured driver risk-taking as reduced distance to other …

Power Of Perception: The Role Of Perceived Caregiver Mindset Beliefs On Undergraduate Student Academic Engagement, Katherine R. Tanaka

Theses and Dissertations--Psychology

Promoting academic engagement is vital for college student success. Researchers have explored factors like growth mindset, the belief that intelligence can improve with effort, as a driver of academic engagement. Beyond personal mindset, students’ perceptions of key social influences, such as caregivers, also play a role. This study examined how undergraduate students’ own mindsets and perceptions of their caregivers’ mindsets relate to four components of academic engagement: behavioral and emotional engagement, and behavioral and emotional disaffection. Data from undergraduates (N = 1417) were analyzed using surveys, descriptive statistics, hierarchical regression, and exploratory moderation. Students generally reported both a personal …

Cognitive-Behavioral Effects And Sex Differences In Alcohol Use, Mia Radevski

Theses and Dissertations--Psychology

Addiction models (e.g., iRISA model) suggest that excessive substance use can result in behavioral consequences such as decreased response inhibition and increased salience attribution toward alcohol cues. The primary goal of this project was to explore potential sex differences in these characteristics of addiction. This dissertation is comprised of two separate but related studies. Study 1 investigated sex differences in inhibitory control and attentional bias. The central hypotheses are 1) women who reported heavy-drinking would display greater disruptions in behavioral inhibitory control following alcohol-related cues, 2) men who reported heavy-drinking would display greater attentional bias toward alcohol-related cues, and 3) …

Menstrual Cycle Phase And Hormonal Effects On Emotional Eating In Females With Attention-Deficit/Hyperactivity Disorder, Urveesha Nirjar

Theses and Dissertations--Psychology

Previous research has shown that cyclical fluctuations in ovarian hormones can predict changes in ADHD symptoms as well as eating behaviors, particularly emotional eating across the menstrual cycle. Previous studies have so far only examined the effects of estrogen (E2), progesterone (P4) and cycle phase in predicting individual symptoms or disorders such as ADHD or eating disorders or related behaviors separately. The aim of this study is to examine how emotional eating is influenced by naturally occurring hormonal and cycle changes in a sample overrecruited for ADHD. Seventy-eight individuals (assigned female at birth) with menstrual cycles overrecruited for ADHD provided …

Weathering The Storm: Risk And Resiliency Factors In Transgender And Gender-Diverse Youth, Haley R. Hedrick

Doctor of Psychology (PsyD)

Compared with their cisgender peers, transgender and gender-diverse (TGD) youth face unique and significant risk factors and are at increased risk for health disparities due to intersectional psychosocial factors including high prevalence of childhood trauma, discrimination and minority stress, societal stigma, and lack of access to competent, comprehensive, gender-affirming healthcare. A total of 180 participants were included in the current study, comprised of a clinically-derived sample of TGD youth aged 8–20 years (M = 14.42, SD = 2.17), and their parents. The current study examined risk and resilience variables relevant to TGD youth, with specific focus on adverse childhood events, …

Accidental Corporate Social Norms, David Kwok

American University Business Law Review

Corporations deliberately attempt to shape social norms through advertising, publicity, and political contributions. This paper considers the threat of corporations’ accidental influence on social norms and expectations. When corporations have accidents, we frequently focus on direct harms: an oil platform may catch fire and explode, leading to environmental and human losses. These accidents may also impact social norms, though. If users stay with a dominant social networking firm despite repeated data privacy breaches, for example, people might come to accept a lack of data privacy. Dominant firms may inadvertently facilitate rapid reshaping of societal expectations. Judicial recognition of this threat …

High-Frequency Traders: How The Sec Can Tighten Regulation While Maintaining The Benefits Of A Competitive Market, John I. Sanders

American University Business Law Review

In 2010, the so-called “Flash Crash” of the U.S. stock market brought the overlooked practice of high-frequency trading into the spotlight for the first time. Initial efforts to study and curtail the practice, including a transaction fee pilot attempted by the Securities and Exchange Commission in 2018, have been unsuccessful. After outlining the substantial benefits market participants gain from the activities of high-frequency traders, this article argues that there are three potent and readily available tools for limiting the harmful excesses of those traders: (i) aggressively bring market manipulation charges under § 9(a)(2) of the Exchange Act against those who …

Shame Clogs The Arteries Of Love: How To Love In The Face Of Shame And Conditions Of Oppression, Theodore J.M. Siasat

CMC Senior Theses

Love and shame, on its face, are at odds with one another. Love tends to foster connection while shame makes one want to hide and isolate oneself. This thesis aims to resolve this tension, particularly in cases of mistaken shame, where the ashamed agent need not feel ashamed, such as in cases of internalized racism, sexism, etc. To do so, this thesis begins by exploring similar cases of love driving people away, looking at (1) love under conditions of oppression and (2) love as seen in Vida Yao’s “Grace and Alienation,” where she is also concerned with ashamed beloveds. …

Creditors Have Standing To Bring Derivative Actions Against Delaware Llcs In Bankruptcy, John D. Hayes Jr.

Bankruptcy Research Library

(Excerpt)

Delaware limited liability companies ("LLCs") are "creatures of contract" and their corporate structure may vary to resemble corporations, partnerships, or a mix of both. Managers of LLCs—like a director or officer of a corporation—owe fiduciary duties to the entity and its members. Generally, the entity has standing to pursue breach of fiduciary duty claims. It is well established that creditors of a corporate debtor may have standing to pursue breach of fiduciary duty claims against directors through derivative actions. Under Delaware law, the applicable statute does not confer standing for creditors of Delaware LLCs to bring derivative actions on …

Doctoral Dissertations (DBA)

This paper analyzes the changeable impact of economic policy uncertainty and mortgage rates on the supply of new homes for sale in the United States. The homes supply is proxied by the ratio of new homes for sale to new houses sold. The analysis utilizes monthly data from January 1985 to November 2023. The relationship is assessed using least square regression with second order autoregressive correction as well as Bai-Perron multiple breakpoint regression for structural breaks and Markov switching tests for state-dependency. The results demonstrate a significant direct correlation between economic policy uncertainty and housing supply, but only during the …

Economic Policy Uncertainty And Its Impact On Unemployment Rates Among U.S. Ethnic Groups, Melody Shirley Nimoh

Doctoral Dissertations (DBA)

The study aims to investigate the transmission of Economic Policy Uncertainty (EPU) shocks on unemployment rates across different ethnic groups in the United States. The research employs econometric analysis such as regression modeling to determine the relationship between EPU and unemployment rates among African American, Hispanic or Latino American, and White American communities. The study estimates coefficient estimates for the lagged change in EPU and its impact on respective unemployment rates for each ethnic group. This shows that there are statistically significant positive relationships between EPU shocks and unemployment rates across all ethnic groups. An increase in EPU leads to …

A Signal Injection Attack Against Zero Involvement Pairing And Authentication For The Internet Of Things, Isaac Ahlgren, Jack West, Kyuin Lee, George K. Thiruvathukal, Neil Klingensmith

Computer Science: Faculty Publications and Other Works

Zero Involvement Pairing and Authentication (ZIPA) is a promising technique for auto-provisioning large networks of Internet-of-Things (IoT) devices. In this work, we present the first successful signal injection attack on a ZIPA system. Most existing ZIPA systems assume there is a negligible amount of influence from the unsecured outside space on the secured inside space. In reality, environmental signals do leak from adjacent unsecured spaces and influence the environment of the secured space. Our attack takes advantage of this fact to perform a signal injection attack on the popular Schurmann & Sigg algorithm. The keys generated by the adversary with …
