Relational Turbulence And Couples’ Convergence And Divergence In Weekly Highs And Lows During Three Months Of The Covid-19 Pandemic Lockdown, Shaochun Li, Denise Haunani Solomon, Kellie St Cyr Brisini

Faculty Publications

Previous research has found relational benefits of interpersonal emotional convergence. Drawing on relational turbulence theory, we expected that partners’ convergence in emotional high and low points is associated with relational uncertainty, qualities of interdependence, and relational turbulence. These hypotheses were tested using data retrieved from a longitudinal project in which spouses in 64 American married couples independently reported high and low experiences and completed relationship measures every week for ten weeks from June to August of 2020. Results from multilevel models confirmed some of the hypothesized benefits of convergence in highs, but predictions about convergence in lows were largely unsupported. …

Louisiana Agriculture Magazine, Spring 2024, Lsu Agcenter

Louisiana Agriculture

Louisiana’s warm, subtropical climate allows producers to raise an array of crops and livestock. It also provides challenges. Tropical storm winds can lay down rice and cane crops. Ample rain can turn into crop-damaging floods. Last year, a drought struck the southeastern United States, leading to more than $100 million in losses for the cattle sector.

In these cases, LSU AgCenter specialists respond to individual producers’ needs. In each parish AgCenter Extension agents help connect producers with needed resources and become a conduit for the latest knowledge gleaned from scientists at AgCenter research stations across the state.

Callous–Unemotional Traits And Emotion Perception Accuracy And Bias In Youths, Enrica Ciucci, Andrea Baroncelli, Carolina Facci, Stefania Righi, Paul J. Frick

Faculty Publications

This study investigated the associations among conduct problems, callous–unemotional (CU) traits, and indices of emotion recognition accuracy and emotion recognition bias obtained from human faces. Impairments in emotion recognition were considered within broader, impaired emotional and social functioning. The sample consisted of 293 middle-school students (51.19% girls; M age = 12.97 years, SD = 0.88 years). In general, CU traits were associated with less accuracy in recognizing emotions, especially fearful and angry faces, and such deficits in emotional recognition were not associated with conduct problems independent of CU traits. These results support the importance of studying potential deficits in the …

Evaluation Of Organic And Synthetic Herbicide Applications On Weed Suppression In A Conventional Cropping System In Louisiana, Caitlin Denux, Aixin Hou, Lisa Fultz

Faculty Publications

Synthetic herbicides, with their varying modes of action, are well known for their efficiency in the suppression and control of weed species in U.S. agriculture. However, the consequences of using synthetic herbicides without attention to the surrounding environment produce chemical run-off, changes in soil health and soil health conditions, and create herbicide-resistant weeds. These outcomes have encouraged growers to seek alternative methods for their weed management programs or farming operations. Organic production systems and organic pesticides have helped address these challenges related to sustainability and environmental health. However, the use of organic herbicides in a conventional cropping system is not …

Interactive Effects Of Co2, Temperature, And Nitrate Limitation On The Growth And Physiology Of Marine Cyanobacterium Synechococcus Sp. Ccmp 1334, Alyssa K. Sharbaugh

LSU Master's Theses

The marine cyanobacterium Synechococcus sp. CCMP 1334 was grown in a continuous culture system on a 12:12 h light:dark cycle at all combinations of low and high pCO2 (400 and 1000 ppmv, respectively), nitrate availability (nitrate-limited and nutrient-replete conditions), and temperatures of 21°C, 24°C, 28°C, 32°C, and 35°C. The maximum median nutrient-replete growth rate was ~1.15 d−1 at 32 –35°C. Median growth rates at 1000 ppmv pCO2 were higher than those at 400 ppmv at all temperatures, but most of the differences were statistically insignificant. Carbon:nitrogen ratios were independent of pCO2 at a fixed relative growth rate but decreased with …

After The Storm: Associations Of Hope And Post-Traumatic Growth In Hurricane Ida Recovery In Younger And Older Adults, Piper J. Bordes

LSU Master's Theses

In recent years, there has been an increase in interest among researchers to understand the impact of severe weather events on measures of health and well-being across the adult lifespan. Previous studies have shown that older age and state hope may act as protective factors that are associated with reduced mental health impacts of hurricanes and flooding. While most prior studies have examined the physical and mental health impacts of severe weather events, very few studies have examined post-traumatic growth in a disaster context, and virtually no prior studies have directly compared younger and older adult samples. Therefore, the present …

An Analysis And Ontology Of Teaching Methods In Cybersecurity Education, Sarah Buckley

LSU Master's Theses

The growing cybersecurity workforce gap underscores the urgent need to address deficiencies in cybersecurity education: the current education system is not producing competent cybersecurity professionals, and current efforts are not informing the non-technical general public of basic cybersecurity practices. We argue that this gap is compounded by a fundamental disconnect between cybersecurity education literature and established education theory. Our research addresses this issue by examining the alignment of cybersecurity education literature concerning educational methods and tools with education literature.

In our research, we endeavor to bridge this gap by critically analyzing the alignment of cybersecurity education literature with education theory. …

Her Seat At The Table: A Phenomenological Study Exploring The Lived Experiences Of Black Women Education Policymakers, Vickey R. Silas

LSU Doctoral Dissertations

ABSTRACT

This transcendental phenomenological study explored the lived experiences of Black women leaders as education policymakers to understand the essence of their journey to leadership positions and the impetus behind their decision-making. Despite progress, Black women remain marginalized and underrepresented in policymaking leadership roles and decision-making spaces (Griffin et. al, 2013). They face challenges that are intersectional like gender and race. My research question was what are the lived experiences of Black women education policymakers and how do these experiences impact their decision-making? While employing a transcendental phenomenological approach, I acknowledged my biases through reflexivity and bracketed them while also …

Mentorship Within Developmental Networks: A Phenomenological Study Of Black Women Tenured Associate Professors And Their Path Toward Full Professor, Jenifer F. Godfrey

LSU Doctoral Dissertations

The problem of inadequate representation of Black women in tenure track faculty positions is both pronounced and longstanding. With Black women making up less than 2% of full professors, this is particularly true at institutions categorized as R1 – Doctoral Universities – Very high research activity by The Carnegie Classification of Institutions of Higher Education. College faculty have long been the focus of scholarly research. However, studies focused on mentorship to be promoted to full professor for associate professors generally, and Black women associate professors specifically, are lacking. Using a conceptual framework that defined mentorship broadly as developmental networks and …

Reassignment Of A Junior Synonym Of Lepisosteus Oculatus Winchell 1864 To L. Platostomus Rafinesque 1820, Daniel Sinopoli, Thomas J. Near, Solomon R. David, Prosanta Chakrabarty

Faculty Publications

The foundation for the current taxonomy of Lepisosteidae (gars) was laid by Suttkus (1963) and Wiley (1976); these authors recognized only two extant genera as valid, Lepisosteus and Atractosteus. These authors also only recognized seven living species of gars and assigned several previously recognized species as junior synonyms. One of these, Lepisosteus oculatus Winchell 1864 possesses five junior synonyms: Cylindrosteus latirostris Girard 1858, Cylindrosteus productus Cope 1865, Cylindrosteus agassizii Duméril 1870, Cylindrosteus zadockii Duméril 1870 and Cylindrosteus bartonii Duméril 1870. Cylindrosteus zadockii was described from two syntypes collected from the “Upper Mississippi River” (MHNH 5799, 5800; Figure 1), and was …

The Trump Effect: How Partisanship Shapes Perceptions Of The Fbi, Carly A. Watts

LSU Master's Theses

Following the 2016 presidential election, some Republicans viewed the Federal Bureau of Investigation (FBI) as politically biased because the agency investigated the Trump campaign's possible collusion with the Russian government. Soon after, public opinion polling found that Republicans had diminishing levels of support for the agency. Using the 2020 ANES, I examine how partisanship affects perceptions of the FBI. I hypothesize that the relationship between partisanship and FBI evaluations is conditional on an individual's support for Donald Trump. The results from my analysis suggest that as support for Trump increases, the relationship between Republican partisan strength and FBI evaluations weakens.

Investigation Of Gas Dynamics In Water And Oil-Based Muds Using Das, Dts, And Dss Measurements, Temitayo S. Adeyemi

LSU Master's Theses

Reliable prediction of gas migration velocity, void fraction, and length of gas-affected region in water and oil-based muds is essential for effective planning, control, and optimization of drilling operations. However, there is a gap in our understanding of gas behavior and dynamics in water and oil-based muds. This is a consequence of the use of experimental systems that are not representative of field-scale conditions. This study seeks to bridge the gap via the well-scale deployment of distributed fiber-optic sensors for real-time monitoring of gas behavior and dynamics in water and oil-based mud. The aforementioned parameters were estimated in real-time using …

Prescribed Fire Effects On Microbial Communities And Functions In Managed Ecosystems, Viet Dao

LSU Doctoral Dissertations

Microbes (both fungi and bacteria) serve important ecosystem functional roles in nutrient cycling and decomposition, which affect ecosystem response following disturbances such as prescribed fire. A multitude of abiotic and biotic factors influence microbial community compositions, which then drive microbial ecosystem functions. The factors driving microbial communities further change due to fire disturbances and progression with time. Although prescribed fire is commonly used as a technique for ecosystem management, the effects of fire on microbial communities or their functions are simply understudied. Ecosystem management decisions tend to focus on plant and ecosystem post-fire responses. Thus, incorporation of fire effects on …

You’Re Looking Very Shane Today: Rhetorical Field Methods & The Materiality Of Queer Mediated Representation For Sapphic Women, Ariel L. Kizer

LSU Doctoral Dissertations

When marginalized communities are left without real-life mentors, they often turn to media as a guide. In this project I assert that mediated sapphic woman characters impact the identity development and everyday experiences for sapphic women in material ways. I explore what mediated narratives sapphic women consume and analyze how these messages become symbolic rhetorical tools that queer women rhetorically mobilize to narrativize and negotiate their queer identities. To achieve this goal, I utilized rhetorical field methods by interviewing 20 queer women ranging from the ages of 25-40 in dyadic, semi structured interviews. These women use varying terms to label …

Characterizing And Mitigating Transient Noise In Ligo Observatories For Gravitational Wave Detection, Jane Glanzer

LSU Doctoral Dissertations

The existence of gravitational waves is predicted by Albert Einstein's Theory of General Relativity. Commonly referred to as "ripples in spacetime", these waves are generated by some of the most violent and energetic processes in the universe. Despite their theoretical prediction over a century ago, it wasn't until 2015 that the Advanced LIGO (aLIGO) interferometers in Hanford, WA and Livingston, LA directly detected gravitational waves for the first time, confirming Einstein's theory and ushering in a new era of astrophysics.

Detecting gravitational waves requires incredible precision. Because of the extreme sensitivity required, it is possible for the gravitational wave data …
