Development And Initial Validation Of The Adult Coping Inventory, Kristen Hollas

LSU Master's Theses

There are few psychometrically sound measures for assessing coping in adults. For example, a widely used measure of coping, the COPE, has highly unstable sub-scale analyses (Lyne & Roger, 2000). The scarcity of instruments developed using evidence based “best practice” is concerning as coping skills are linked to a variety of positive and negative outcomes. For example, positive coping skills have been linked to better health outcomes among various populations (Garnefski & Kraaij, 2006; Littleton, Horsley, John & Nelson, 2007). This study aimed to address the lack of psychometrically sound measures of coping for an adult population. The current study …

Cross-Sectional Associations Between The Neighborhood Built Environment And Physical Activity In A Rural Setting: The Bogalusa Heart Study, Jeanette Gustat, Christopher E. Anderson, Queendaleen C. Chukwurah, Maeve E. Wallace, Stephanie T. Broyles, Lydia A. Bazzano

Population and Public Health Science Faculty Publications

Background: Insufficient physical activity (PA) is a common health risk and more prevalent in rural populations. Few studies have assessed relationships between the built environment and PA in rural settings, and community policy guidance to promote PA through built environment interventions is primarily based on evidence from urban studies. Methods: Participants in the Bogalusa Heart Study, a longitudinal study in rural Louisiana, with International Physical Activity Questionnaire data from 2012 to 2013 and a valid residential address (N = 1245) were included. PA was summarized as the number of weekly metabolic equivalent (MET)-minutes of total, transportation, and leisure time PA. …

Quantum-Limited Squeezed Light Detection With A Camera, Elisha S. Matekole, Savannah L. Cuozzo, Nikunjkumar Prajapati, Narayan Bhusal, Hwang Lee, Irina Novikova, Eugeniy E. Mikhailov, Jonathan P. Dowling, Lior Cohen

Faculty Publications

We present a technique for squeezed light detection based on direct imaging of the displaced-squeezed-vacuum state using a CCD camera. We show that the squeezing parameter can be accurately estimated using only the first two moments of the recorded pixel-to-pixel photon fluctuation statistics, with accuracy that rivals that of the standard squeezing detection methods such as a balanced homodyne detection. Finally, we numerically simulate the camera operation, reproducing the noisy experimental results with low signal samplings and confirming the theory with high signal samplings.

Young Adults' Short-Term Trajectories Of Moderate Physical Activity: Relations With Self-Evaluation Processes, Alex .. Garn, Kelly L. Simonton

Faculty Publications

Young adults face numerous barriers that can undermine their engagement in healthy behaviors. For example, young adults on average experience disproportionally large declines in physical activity (PA) participation compared to other demographic groups. Self-evaluation processes may help explain these declines. This study investigated young adults' weekly trajectories of moderate physical activity, exploring self-evaluation processes, including self-efficacy and shame as time-varying covariates. A total of 71 young adults (Mage = 21.25,SD= 1.18; 55% male) reported moderate physical activity, exercise self-efficacy, and anticipated shame toward exercise once a week for 5 weeks. Latent growth curve models showed that a linear slope fit …

Machine Intelligence For Nerve Conduit Design And Production, Caleb E. Stewart, Chin Fung Kelvin Kan, Brody R. Stewart, Henry W. Sanicola Iii, Jangwook P. Jung, Olawale A. R. Sulaiman, Dadong Wang

Faculty Publications

Nerve guidance conduits (NGCs) have emerged from recent advances within tissue engineering as a promising alternative to autografts for peripheral nerve repair. NGCs are tubular structures with engineered biomaterials, which guide axonal regeneration from the injured proximal nerve to the distal stump. NGC design can synergistically combine multiple properties to enhance proliferation of stem and neuronal cells, improve nerve migration, attenuate inflammation and reduce scar tissue formation. The aim of most laboratories fabricating NGCs is the development of an automated process that incorporates patient-specific features and complex tissue blueprints (e.g. neurovascular conduit) that serve as the basis for more complicated …

Avoided Quantum Criticality In Exact Numerical Simulations Of A Single Disordered Weyl Cone, Justin H. Wilson, David A. Huse, S. Das Sarma, J. H. Pixley

Faculty Publications

Existing theoretical works differ on whether three-dimensional Dirac and Weyl semimetals are stable to a short-range-correlated random potential. Numerical evidence suggests the semimetal to be unstable, while some field-theoretic instanton calculations have found it to be stable. The differences go beyond method: the continuum field-theoretic works use a single, perfectly linear Weyl cone, while numerical works use tight-binding lattice models which inherently have band curvature and multiple Weyl cones. In this work, we bridge this gap by performing exact numerics on the same model used in analytic treatments, and we find that all phenomena associated with rare regions near the …

On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85-14+21 Mm and 66-18+17 Mm (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of …

Security Analysis Of The Anonabox Pro, Devi Sowjanya Vempati

LSU Master's Theses

The security posture of critical network appliances, such as routers, switches, and firewalls, is crucial as these devices provide the first line of defense against malicious actors. As there is typically no endpoint security software, such as anti-virus available for these devices, it is crucial that vendors release timely updates for vulnerabilities and that customers apply them quickly. The research effort documented in this thesis describes a developed methodology for triaging known vulnerabilities in network devices, assessing the security posture of device vendors, and locating likely weak points in released firmware images. To highlight this methodology, the Anonabox security appliance …

Creating Collaborative Subject Guides For Multi-Insitutional Digital Collection: A Case Study From The Louisiana Digital Library, Sl Ziegler, Leah Powell

Faculty Publications

This case study focuses on the development of subject guides for the Louisiana Digital Library (LDL), a state-wide digital repository for digital cultural heritage. While subject guides are always important for navigating large collections, during the state-wide shutdown of libraries due to the COVID-19 pandemic, the need for the guides was greater than ever. In keeping with the LDL’s multi-institutional and collaborative nature, representatives from seven Louisiana-based institutions responded to an open call to form a rapid-response working group. Within three weeks, ten guides were developed and published. Equally important, an iterative workflow for building and updating guides was established …

A Metacognitive Approach To Reconsidering Risk Perceptions And Uncertainty: Understand Information Seeking During Covid-19, Yan Huang, Chun Yang

Faculty Publications

The study examined the psychological drivers of information-seeking behaviors during the coronavirus disease 2019 (COVID-19) outbreak. Employing a two-wave (from April 16, 2020, to April 27, 2020) survey design (N= 381), the study confirmed that both risk perceptions and uncertainty were important antecedents to information seeking and that their effects were linked to emotional appraisals of the risk situation. Findings revealed nuanced relationships between these two constructs and emotional appraisals. Danger appraisal was positively associated with perceived susceptibility and susceptibility uncertainty but negatively related to severity uncertainty; hope appraisal depended on the interaction between uncertainty and risk perceptions. Implications of …

The Pull-To-Stay Effect: Influence Of Sales Managers' Leadership Worthiness On Salesperson Turnover Intentions, Vishag Badrinarayanan, Aditya Gupta, Nawar N. Chaker

Faculty Publications

Given that salesperson turnover is a significant problem for sales organizations, sales researchers have devoted a lot of attention toward explicating various drivers and mitigators of salesperson turnover intentions. Within this domain, consistent with the popular sentiment "employees don't quit their jobs, they quit their bosses," scholars have explored sales manager-related triggers such as leadership style, salesperson - sales manager relational exchange, and several managerial characteristics. We extend this stream of research by developing and testing a framework of salespersons' perceptions of their manager'sleadership worthiness- a higher-order construct comprising of competence, charisma, and behavioral integrity - and its subsequent impact …

Under Pressure: Time Management, Self-Leadership, And The Nurse Manager, Elizabeth Goldsby, Michael Goldsby, Christopher B. Neck, Christopher P. Neck

Faculty Publications

Decision making by nurses is complicated by the stress, chaos, and challenging demands of the work. One of the major stressors confronting nurses is perceived time pressure. Given the potential negative outcomes on nurses due to perceived time pressures, it seems logical that a nurse manager's ability to lead nurses in moderating this time pressure and in turn to make better decisions could enhance nurse well-being and performance. Paralleling research in the nursing literature suggests that, in order to improve patients' judgement of the care they received, nurse managers should embrace ways to lower nurses' perceived time pressure. In this …

Clinical Research Faculty Publications

Background: Less than one-third of women gain an appropriate amount of weight during pregnancy, which can influence the long-term health of both the mother and the child. Economically disadvantaged women are the most vulnerable to maternal obesity, excessive weight gain during pregnancy, and poor birth outcomes. Effective and scalable health care strategies to promote healthy weight gain during pregnancy specifically tailored for these women are lacking. Objective: This paper presents the design and protocol of a biphasic, community-based eHealth trial, SmartMoms in WIC, to increase the adherence to healthy gestational weight gain (GWG) recommendations in low-income mothers receiving women, infant, …

Α -Logarithmic Negativity, Xin Wang, Mark M. Wilde

Faculty Publications

The logarithmic negativity of a bipartite quantum state is a widely employed entanglement measure in quantum information theory due to the fact that it is easy to compute and serves as an upper bound on distillable entanglement. More recently, the κ entanglement of a bipartite state was shown to be an entanglement measure that is both easily computable and has a precise information-theoretic meaning, being equal to the exact entanglement cost of a bipartite quantum state when the free operations are those that completely preserve the positivity of the partial transpose [Xin Wang and Mark M. Wilde, Phys. Rev. Lett. …

Ab Initio Leading Order Effective Potentials For Elastic Nucleon-Nucleus Scattering, M. Burrows, R. B. Baker, Ch Elster, S. P. Weppner, K. D. Launey, P. Maris, G. Popa

Faculty Publications

Background: Calculating microscopic effective interactions (optical potentials) for elastic nucleon-nucleus scattering has already led to a large body of work. For leading-order calculations a nucleon-nucleon (NN) interaction and a one-body density of the nucleus were taken as input to rigorous calculations of microscopic full-folding calculations. Purpose: Based on the spectator expansion of the multiple scattering series, we employ a chiral next-to-next-to-leading order (NNLO) nucleon-nucleon interaction on the same footing in the structure as well as in the reaction calculation to obtain an effective potential for nucleon-nucleus elastic scattering, consistent in leading-order, which includes the spin of the struck target nucleon.Methods: …

Multiple Decrement Life Tables Of Cephus Cinctus Norton (Hymenoptera: Cephidae) Across A Set Of Barley Cultivars: The Importance Of Plant Defense Versus Cannibalism, Buddhi B. Achhami, Robert K.D. Peterson, Jamie D. Sherman, Gadi V.P. Reddy, David K. Weaver

Faculty Publications

Accurately estimating cause-specific mortality for immature insect herbivores is usually difficult. The insects are exposed to abiotic and biotic mortality factors, causing cadavers to simply disappear before cause of mortality can be recorded. Also, insect herbivores are often highly mobile on hosts, making it difficult to follow patterns for individuals through time. In contrast, the wheat stem sawfly, Cephus cinctus Norton, spends its entire egg, larval, and pupal period inside a host stem. Therefore, with periodic sampling stage-specific causes of mortality can be ascertained. Consequently, we examined C. cinctus mortality in eight barley, Hordeum vulgare L., cultivars in two locations …

Antixenosis, Antibiosis, And Potential Yield Compensatory Response In Barley Cultivars Exposed To Wheat Stem Sawfly (Hymenoptera: Cephidae) Under Field Conditions, Buddhi B. Achhami, Gadi V.P. Reddy, Jamie D. Sherman, Robert K.D. Peterson, David K. Weaver

Faculty Publications

Wheat stem sawfly, Cephus cinctus Norton, is an economically serious pest of cereals grown in North America. Barley cultivars were previously planted as resistant crops in rotations to manage C. cinctus, but due to increasing levels of injury to this crop, this is no longer a valid management tactic in Montana. Therefore, we aimed to understand antixenosis (behavioral preference), antibiosis (mortality), and potential yield compensation (increased productivity in response to stem injuries) in barley exposed to C. cinctus. We examined these traits in eight barley cultivars. Antixenosis was assessed by counting number of eggs per stem and antibiosis was assessed …

The Validity, Time Burden, And User Satisfaction Of The FoodimageTm Smartphone App For Food Waste Measurement Versus Diaries: A Randomized Crossover Trial, Brian E. Roe, Danyi Qi, Robbie A. Beyl, Karissa E. Neubig, Corby K. Martin, John W. Apolzan

Faculty Publications

© 2020 Elsevier B.V. The FoodImageTM smartphone app transmits users’ photographs of food selection and food waste to researchers, and includes user-tagged information about waste reasons and destination. Twenty-four participants were trained to record food waste using FoodImage, food waste diaries requiring visual estimation of waste quantities, and diaries requiring scale weights. Participants used each method during three staged food-waste scenarios (food preparation, eating, and clean-out) in a randomized crossover trial. Two participants had extreme values for the weighed diary method; therefore, accuracy results are reported with and without these two participants’ data. Error was calculated as waste estimated with …

Twenty One Years After The Publication Of The Generalized Faustmann Formula, Sun Joseph Chang

Faculty Publications

In this paper, I discuss developments of the generalized Faustmann formula since its publication in 1998. They included the formula for even-aged plantation management, uneven-aged management and forest valuation. These formula were followed by those for forest property taxation and valuation under taxation, the generalized van Kooten model, and the generalized Reed model as well as the uneven-aged management formula with carbon sequestration. The dynamic, incremental solution for the generalized Faustmann formula was then discussed. Pressler's indicator rate formula turned out to be equally applicable under the generalized Faustmann formula. Further, it enables the incorporation of risk preference to deal …
