Challenges In Quantifying Air‐Water Carbon Dioxide Flux Using Estuarine Water Quality Data: Case Study For Chesapeake Bay, Maria Herrmann, Raymond G. Najjar, Fei Da, Jaclyn R. Friedman, Marjorie A. M. Friedrichs, Sreece Goldberger, Alana Menendez, Elizabeth H. Shadwick, Edward G. Stets, Pierre St-Laurent

Publications and Research

Estuaries play an uncertain but potentially important role in the global carbon cycle via CO₂ outgassing. The uncertainty mainly stems from the paucity of studies that document the full spatial and temporal variability of estuarine surface water partial pressure of carbon dioxide ( pCO₂). Here, we explore the potential of utilizing the abundance of pH data from historical water quality monitoring programs to fill the data void via a case study of the mainstem Chesapeake Bay (eastern United States). We calculate pCO₂ and the air-water CO₂ flux at monthly resolution from 1998 to …

Measuring The Temporal Stability Of Near-Repeat Crime Patterns: A Longitudinal Analysis, David Hatten, Eric L. Piza

Publications and Research

This study investigates the temporal stability of identified near-repeat robbery patterns in Newark, New Jersey. With one noteworthy exception, scholars have yet to explore the temporal stability of identified spatiotemporal crime clusters. Furthermore, researchers have yet to measure the near-repeat phenomenon longitudinally. To fill this gap, this study employs a longitudinal design to measure variation in effect size and significance of identified near- repeat crime patterns across 13 “rolling” one-year time periods within a 2-year study period (January 2015–December 2016). Temporal instability was found within two out of six spatiotemporal crime clusters. Results are reported in the form of formalized …

Reduced Egocentric Bias When Perspective-Taking Compared With Working From Rules, Steven Samuel, Anna Frohnwieser, Robert Lurz, Nicola S. Clayton

Publications and Research

Previous research has suggested that adults are sometimes egocentric, erroneously attributing their current beliefs, perspectives, and opinions to others. Interestingly, this egocentricity is sometimes stronger when perspective-taking than when working from functionally identical but non-perspectival rules. Much of our knowledge of egocentric bias comes from Level 1 perspective-taking (e.g., judging whether something is seen) and judgements made about narrated characters or avatars rather than truly social stimuli such as another person in the same room. We tested whether adults would be egocentric on a Level 2 perspective-taking task (judging how something appears), in which they were instructed to indicate on …

A Role For Retinoids In The Treatment Of Covid-19?, Steven E. Trasino

Publications and Research

The 2020 global outbreak of the novel coronavirus (SARS-CoV-2 or COVID-19) is a serious threat to international health, and thus, there is an urgent need for discoverynof novel therapies or use of repurposed drugs that can make a significant impact on slowing the spread of the virus. Type 1 interferons (IFN-I) are a family cytokines of the early innate immune response to viruses that are being tested against SARSCoV- 2. However, coronaviruses similar to SARS-CoV-2 can suppress host IFN-I antiviral responses. Retinoids are a family molecules related to vitamin A that possess robust immune-modulating properties, including the ability to increase …

Post-Infectious Sequela Of Sars-Cov-2 Infection In Adults And Children: An Overview Of Available Agents And Clinical Responsiveness, David S. Younger

Publications and Research

The SARS-CoV-2 2019 pandemic has created challenges to managing the post-infectious autoimmune consequences of a disease that leads to the high case fatality in adults and children. The spectrum of agents available to modulate and suppress the immune system in combination with other appropriate antiviral antibiotics and life support measures is reviewed. All of the agents envisioned to treat Covid-19 disorders, including a newly recognized pediatric multi-system inflammatory syndrome, impact post-infectious mechanisms in keeping with the multiplier effect of infection, immunity and inflammation known as I-Cubed (I3).

Somatic Marker Production Deficits Do Not Explain The Relationship Between Psychopathic Traits And Utilitarian Moral Decision Making, Shawn E. Fagan, Liat Kofler, Sarah Riccio, Yu Gao

Publications and Research

In moral dilemma tasks, high levels of psychopathic traits often predict increased utilitarian responding—specifically, endorsing sacrificing one person to save many. Research suggests that increased arousal (i.e., somatic marker production) underlies lower rates of utilitarian responding during moral dilemmas. Though deficient somatic marker production is characteristic of psychopathy, how this deficit affects the psychopathy–utilitarian connection remains unknown. We assessed psychopathic traits in undergraduates, as well as behavioral performance and skin conductance level reactivity (SCL-R; a measure of somatic marker production) during a moral dilemma task. High psychopathic traits and low SCL-R were associated with increased utilitarian decisions in dilemmas involving …

Studying Public Perception About Vaccination: A Sentiment Analysis Of Tweets, Viju Raghupathi, Jie Ren, Wullianallur Raghupathi

Publications and Research

Text analysis has been used by scholars to research attitudes toward vaccination and is particularly timely due to the rise of medical misinformation via social media. This study uses a sample of 9581 vaccine-related tweets in the period 1 January 2019 to 5 April 2019. The time period is of the essence because during this time, a measles outbreak was prevalent throughout the United States and a public debate was raging. Sentiment analysis is applied to the sample, clustering the data into topics using the term frequency–inverse document frequency (TF-IDF) technique. The analyses suggest that most (about 77%) of the …

Snapshots Of Human Anatomy, Locomotion, And Behavior From Late Pleistocene Footprints At Engare Sero, Tanzania, Kevin Hatala, William E. H. Harcourt-Smith, Adam D. Gordon, Brian W. Zimmer, Brian G. Richmond, Briana L. Pobiner, David J. Green, Adam Metallo, Vince Rossi, Cynthia M. Liutkus-Pierce

Publications and Research

Fossil hominin footprints preserve data on a remarkably short time scale compared to most other fossil evidence, offering snapshots of organisms in their immediate ecological and behavioral contexts. Here, we report on our excavations and analyses of more than 400 Late Pleistocene human footprints from Engare Sero, Tanzania. The site represents the largest assemblage of footprints currently known from the human fossil record in Africa. Speed estimates show that the trackways reflect both walking and running behaviors. Estimates of group composition suggest that these footprints were made by a mixed-sex and mixed-age group, but one that consisted of mostly adult …

Redefining Gender & Gender Expression Through Self-Perceptions & Self-Reflections, Deborah O. Ade

Publications and Research

As societies evolve policies are developed to recognize and formalize these changes. One current context for change is New York City and the concept that has undergone significant change is gender. Many individuals no longer identify with the traditional binary distinction of male or female. Subsequently, new gender categories have emerged (e.g., bi-gender, pan gender, androgynous). Indeed, a total of 31 gender categories have been recognized by the NYC Commission of Human Rights. The goal behind this acknowledgement is to encourage equitable treatment and respect of all individuals within the workplace. NYC businesses that do not accommodate individuals identifying with …

Nato Enlargement And Us Grand Strategy: A Net Assessment, Rajan Menon, William Ruger

Publications and Research

NATO did not dissolve following the Soviet Union’s collapse and the end of the Cold War. Instead, the alliance expanded, in stages—from 16 members at its Cold War peak to 30 in 2020. While NATO enlargement alone did not cause the deterioration of US–Russian relations, it did contribute significantly to that outcome. Champions of NATO expansion aver that it maintains peace in Europe and promotes democracy in East-Central Europe. They add that Russia has nothing to fear. But Russia’s leaders have always seen NATO expansion differently. The article also examines NATO’s enlargement as it relates to US post-Cold War grand …

Uptake Of Co(Ii) Ions From Aqueous Solutions By Low-Cost Biopolymers And Their Hybrid, Mohamdia Nassar, Abel E. Navarro

Publications and Research

Alginate hydrogel beads (AB), spent peppermint leaf (PM), and a hybrid adsorbent of these two materials (ABPM), were studied as potential adsorbents of Cobalt (II) ions from aqueous solutions in batch system at room temperature. Equilibrium parameters such as solution pH, mass of adsorbent and the presence of a crowding agent on the adsorption of Co(II) ions were investigated. The results indicate that Co(II) uptake is maximized at pH values higher than 5, with adsorbent doses in the range 120-200 mg. Co(II) adsorption followed the trend AB > ABPM > PM with adsorption percentages of 77%, 71% and 64%, respectively.

An In-Depth Look At P-Adic Numbers, Xiaona Zhou

Publications and Research

In this study, we consider $p$-adic numbers. We will also study the $p$-adic norm representation of real number, which is defined as $\mathbb{Q}_p = \{\sum_{j=m}^{\infty }a_j p^j: a_j \in \mathbb{D}_p, m\in\mathbb{Z}, a_m\neq 0\} \cup \{0\}$, where $p$ is a prime number. We explore properties of the $p$-adics by using examples. In particular, we will show that $\sqrt{6},i \in \mathbb{Q}_5$ and $\sqrt{2} \in \mathbb{Q}_7 $. $p$-adic numbers have a wide range of applicationsnin fields such as string theory, quantum mechanics, and transportation in porous disordered media in geology.

Sleep-Wake Disturbances In Mild Traumatic Brain Injury: Meta Analysis Of Literature And Modeling Of Cerebral Tissue Vulnerability, Xiangfu Zhang, Subhendra Sarkar, Mary A. Browne

Publications and Research

Sleep disturbance is a frequent complaint for patients with mild traumatic brain injury (mTBI), it can prolong recovery, and the oxidative stress from lack of sleep could worsen other secondary damages of mTBI. The common types of sleep disturbance of mTBI include insomnia, daytime sleepiness, and obstructive sleep apnea. Conventional imaging often fails to detect any abnormalities in mTBI, and the etiology of sleep disturbance is still unclear. Based on the analysis of current published neurobiological and imaging literature, multiple factors could play a role leading to sleep disturbance in mTBI, however, we have focused on the diencephalon, melatonin and …
