Tracking Charge Migration With Frequency-Matched Strobo-Spectroscopy, Kyle A. Hamer, Aderonke S. Folorunso, Kenneth Lopata, Kenneth J. Schafer, Mette B. Gaarde, François Mauger

Faculty Publications

We present frequency-matched strobo-spectroscopy (FMSS) of charge migration (CM) in bromobutadiyne, simulated with time-dependent density functional theory. CM + FMSS is a pump-probe scheme that uses a frequency-matched high harmonic generation (HHG)-driving laser as an independent probe step, following the creation of a localized hole on the bromine atom that induces CM dynamics. We show that the delay-dependent harmonic yield tracks the phase of the CM dynamics through its sensitivity to the amount of electron density on the bromine end of the molecule. FMSS takes advantage of the intrinsic attosecond time resolution of the HHG process in which different harmonics …

Attochemistry Regulation Of Charge Migration, Aderonke Folorunso

LSU Doctoral Dissertations

Charge migration (CM) is a coherent attosecond process that involves the movement of localized holes across a molecule. This phenomenon is potentially useful to understand the fundamental principles of photochemistry, such as light harvesting. The first part of this dissertation discusses the molecular modes of attosecond charge migration. In this work, we used first-principles calculations to investigate the modes of charge migration (CM) in halogenated hydrocarbon chains at attosecond timescales. We have simulated the creation of a localized hole on the halogen atom using constrained density functional theory (DFT) and then tracked its subsequent dynamics with time-dependent DFT (TDDFT). Our …

Biology, Ecology, And Management Of Redbanded Stink Bug (Hemiptera: Pentatomidae), Olabimpe O. Okosun, Justin George, Maribel Portilla, James P. Glover, Katherine A. Parys, Gadi V.P. Reddy

Faculty Publications

The redbanded stink bug (RBSB), Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) is an invasive stink bug species and a polyphagous pest of cultivated crops and non-cultivated wild plants. The increase in soybean cultivation during the 1960s-1970s led to the spread of RBSB as an economic pest of soybean throughout South America, especially in Brazil, Argentina, and Uruguay. In the early 2000s, RBSB became an economic concern to US agriculture and is currently a key species in a stink bug complex that damages soybean in many mid-southern states. RBSB causes extensive damage to soybeans and other economically important leguminous crops by feeding …

Madness As Response To Inherent Cultural Conflicts In Anglophone Fiction From 1700 To 2020, Anna Klambauer

Comparative Woman

Madness in literature has a long and colourful history. While its representation varies significantly in different literary periods, madness is nonetheless a consistent theme responding to inherent conflicts of civilisation. Thus, in the eighteenth-century novel, madness is subdued and forced to express itself in the language of rationality, while in the nineteenth century the theme becomes increasingly subversive. In the form of the madwoman trope (Gilbert and Gubar 1979), madness is simultaneously a reaction to restrictive patriarchal norms, and a frame in which the gender conflicts of the time can be safely and effectively played out. In the twentieth century, …

"Too Immoral To Be Narrated By A Woman": Censoring Erotic Fiction Of Arab Women Writers In Girls Of Riyadh And Distant View Of A Minaret And Other Stories, Muhammed Salem

Comparative Woman

In the Arab world, bargaining with censorship has been an ongoing struggle for writers, particularly female authors. How could we explain that only male writers were allowed to discuss sexuality in the Arabic canon, insofar as female characters are portrayed as passive sexual objects? Are Arab women writers victims of double censorship? One is imposed on their fellow male writers, and another is tacit censorship which judges women’s morality based on their writing. Girls of Riyadh (2007) by Saudi novelist, Rajaa Abdullah Alsanea, and Distant View of the Minaret and Other Stories (1987) by Egyptian novelist, Alifa Rifaat, are two …

Women, Animals, Food: Planetary Perspectives On The Non-(Hu)Man, Samu/Elle Striewski

Comparative Woman

The paper comparatively reads Mahasweta Devi’s Pterodactyl, Pirtha, and Puran Sahay (1995) and Margaret Atwood’s The Year of the Flood (2009) to trace the ways in which both novels show the complex intertwinement of the climate crisis with gender, class, race, subalternity, anthropocentrism, and veganism. Bringing together Gayatri C. Spivak’s notion of “planetarity” with ecofeminist philosophy and literary criticism, the article proposes a planetary ecogender reading of the two texts and their representation of the non-man, non-human, and non-subject. Building up further on Jacques Derrida’s critique of carno-phallogocentrism, the pedagogy of a relational ethics of “nurturing” is hence presented …

The COVID-19 pandemic impacted personal and professional life. For academics, research, teaching, and service tasks were upended and we all had to navigate the altered landscape. However, some individuals faced a disproportionate burden, particularly academics with minoritized identities or those who were early career, were caregivers, or had intersecting identities. As comparative endocrinologists, we determine how aspects of individual and species-level variation influence response to, recovery from, and resilience in the face of stressors. Here, we flip that framework and apply an integrative biological lens to the impact of the COVID-19 chronic stressor on our endocrine community. We address how …

Alcohol And Cannabis Dual Use Among Black Adults: Associations With Alcohol Use, Use-Related Problems, And Race-Based Discrimination, Julia D. Buckner, Michael J. Zvolensky, Caroline R. Scherzer

Faculty Publications

Background and Objectives: Black adults who drink alcohol appear at risk for poor alcohol-related outcomes, yet little research has examined whether cannabis use among those who consume alcohol (alcohol-cannabis dual use) is related to worse alcohol-related consequences, as observed in predominantly White samples. Further, it may be that experiencing more race-based discrimination may be related to using multiple substances to cope with such experiences; however, no known studies have examined the impact of race-based discrimination on alcohol-cannabis dual use. Methods: Participants were 270 Black undergraduates who endorsed past-month drinking, 112 of whom endorsed alcohol-cannabis dual use. Results: The dual use …

Rationale And Challenges For A New Instrument For Remote Measurement Of Negative Symptoms, David Gordon Daniel, Alex S. Cohen, Philip D. Harvey, Dawn I. Velligan, William Z. Potter, William P. Horan, Raeanne C. Moore, Stephen R. Marder

Faculty Publications

There is a broad consensus that the commonly used clinician-administered rating scales for assessment of negative symptoms share significant limitations, including (1) reliance upon accurate self-report and recall from the patient and caregiver; (2) potential for sampling bias and thus being unrepresentative of daily-life experiences; (3) subjectivity of the symptom scoring process and limited sensitivity to change. These limitations led a work group from the International Society of CNS Clinical Trials and Methodology (ISCTM) to initiate the development of a multimodal negative symptom instrument. Experts from academia and industry reviewed the current methods of assessing the domains of negative symptoms …

Faculty Publications

The desire to live in a healthy “green” environment is becoming increasingly important to global populations. The term “green” is overused, confusing, and inconsistently used among and between consumers, corporate enterprises, environmental groups, government entities, and other segments globally. Research studies suggest that defining and applying the term “green” to behaviors and decision-making is constantly changing, further complicating the study of corporate and consumer environmental responsibility. In this study, we focus on the consumer. Not all consumers behave the same or have the same beliefs and perceptions regarding what is environmentally “green.” As such, we segmented consumers in Slovakia into …
