Verbal Response Inhibition And Stuttering In Adults, Shanley Belle Treleaven

LSU Doctoral Dissertations

Many adults who stutter (AWS) attempt to modify or suppress their stuttered speech daily. The ability to effectively suppress motoric behavior after initiation relies on executive functions such as inhibition – specifically verbal inhibition – a challenging task regardless of clinical status. Minimal published data are available about verbal inhibition in non-stuttering adults, and no data are available for AWS. Researchers have reported slower inhibition for AWS during manual tasks, but inconsistent relationships have been found between manual and verbal inhibition. It is often presumed that inhibition differences in AWS, if detected, would be associated with greater difficulties suppressing the …

Village Folk: Exploring The Female Black School Counselor's Perception Of Role Confusion And Burnout In Urban Schools In South Louisiana, Christianne Leah Ricard

LSU Doctoral Dissertations

This qualitative study examined female Black school counselor’s perceptions regarding their role when working with students – specifically Black students. More so, this study looked at cultural influence on female Black school counselors’ thoughts and feelings relative to role confusion and burnout. Black Feminist Thought and Maslow’s Hierarchy of Needs served as the theoretical framework that guided this study. In consideration for cultural differences, female Black school counselor’s perceptions can be used to further explain the phenomenon of role confusion and burnout.

More than 10 invitations to participate, interviews were conducted with five female Black school counselors. The research questions …

Relational Turbulence And Perceptions Of Social Network Support For Parents Of Children With Autism Spectrum Disorder, Kellie St Cyr Brisini, Denise Haunani Solomon

Faculty Publications

A wealth of research indicates that social support positively influences parental and family well-being in families of children with disabilities; however, not all supportive efforts are positively received. This study employs the framework of relational turbulence theory to examine evaluations of social support from social network members among parents of children with Autism Spectrum Disorder (ASD). In a cross-sectional survey, ninety-four parents of children with ASD (47 heterosexual couples) reported a social network member to whom they disclose issues regarding their marriage and evaluated that network member’s support for their marriage and their parenting. Results of actor-only interdependence modeling demonstrated …

Third-Variable Effect Analysis With Multilevel Additive Models, Qingzhao Yu, Bin Li

Faculty Publications

Third-variable effect refers to the effect transmitted by third-variables that intervene in the relationship between an exposure and a response variable. Third-variable effect analysis has been broadly studied in many fields. However, it remains a challenge for researchers to differentiate indirect effect of individual factor from multiple third-variables, especially when the involving variables are of hierarchical structure. Yu et al. (2014) defined third-variable effects that were consistent for all different types of response (categorical or continuous), exposure, or third-variables. With these definitions, multiple third-variables can be considered simultaneously, and the indirect effects carried by individual third-variables can be separated from …

Exploring New And Modified Rejection-Type Thresholds Using Cricket Snack Crackers, Ryan Ardoin, Ross Romero, Brian Marx, Witoon Prinyawiwatkul

Faculty Publications

Recently, sensory threshold concepts have been expanded to include affective perceptions of foods and beverages, especially measures of product rejection; however, each threshold interpretation depends largely on the methodology employed. By substituting cricket powder for whole-wheat flour in snack crackers (0%, 5%, 10%, 15%, and 20%), we proposed modifications to two existing threshold methodologies: a modified consumer rejection threshold (M-CRT) using a 2-alternative choice (2-AC) preference test with “no preference” option; and a modified hedonic rejection threshold (M-HRT) based on less-than-neutral hedonic scores according to a one-sample t-test. We also proposed two new concepts: a rejection tolerance threshold (RTT) and …

Objective: International reverse transfer students are international students who begin their postsecondary journey at a four-year institution but subsequently transfer to a community college. In this qualitative study, we examine the lived experiences of international reverse transfers to understand the reasons for reverse-transfer and to understand the students’ learning experiences. Methods: Using a phenomenological approach, we recruited 10 international reverse transfer students attending one four-year university or one of the two community colleges. We conducted individual interviews with all participants and analyzed transcript data through Bourdieu’s sociological theory of field, habitus, and social and cultural capital. Results: We identified three …

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 …

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. …

Readiness To Change And Smoking Expectancies Among Adult Male Substance Users Currently In Substance Use Treatment, Aaron French Waters

LSU Doctoral Dissertations

The primary aims of the current study were to examine if smoking expectancies and readiness to quit smoking, important components in predicting smoking behavior and cessation, changed across time for adult smokers in substance use treatment. Participants (N = 51) were predominantly white (96.1%), adult, male smokers who were admitted to residential substance use treatment. Smoking outcome expectancies and readiness to change smoking were assessed among participants at treatment entry (n = 51), and subsequently at 30 days (n = 13), 60 days (n = 9), and 90 days (n = 3) from treatment entry. …

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 …

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 …

Behavioral Strategies During Incubation Influence Nest And Female Survival Of Wild Turkeys, Ashley K. Lohr, James A. Martin, Gregory T. Wann, Bradley S. Cohen, Bret A. Collier, Michael J. Chamberlain

Faculty Publications

Females must balance physiological and behavioral demands of producing offspring with associated expenditures, such as resource acquisition and predator avoidance. Nest success is an important parameter underlying avian population dynamics. Galliforms are particularly susceptible to low nest success due to exposure of ground nests to multiple predator guilds, lengthy incubation periods, and substantive reliance on crypsis for survival. Hence, it is plausible that nesting individuals prioritize productivity and survival differently, resulting in a gradient of reproductive strategies. Fine-scale movement patterns during incubation are not well documented in ground-nesting birds, and the influence of reproductive movements on survival is largely unknown. …

The Effects Of Relational And Social Behaviors Exhibited By Construction Project Team Members On Relationship Quality And Project Outcomes, James Ogechi Kereri

LSU Doctoral Dissertations

Relational and social behaviors of construction project team members explain team relationships. Whereas relational behaviors have often been studied in construction project team relationships, the current literature is deficient on the social behaviors. The literature review revealed seven relational behaviors (i.e., harmonization of conflict, propriety of means, restraint of power, reliance and expectation, contractual solidarity, flexibility, and reciprocity) and three social behaviors (i.e., past experience, benevolence, and integrity) commonly exhibited by construction project team members. Through a binomial logistic regression, research findings revealed that past experience was a significant (p < 0.01) predictor for five of the seven relational behaviors while benevolence and integrity were each significant (p < 0.01) predictors for three of the seven relational behaviors. Overall, out of the seven relational behaviors, only propriety of means is predicted by all the three social behaviors. Through multinomial regression, the results indicated that there is not enough evidence to show a relationship between the dimensions of relationship quality and project outcomes. However, there is a relationship between relationship embeddedness and project outcomes. Through internal and external validation, the prediction models performed well based on both positive predictive values and negative predictive values.

From a relationship management standpoint, this research introduces relational and …

Moderators Of Academic Performance And Symptom Severity In Adolescents With Attention-Deficit/Hyperactivity Disorder, Ryan Nicole Cummins

LSU Doctoral Dissertations

Research has documented the relationship between attention-deficit/hyperactivity disorder (ADHD) symptom severity and poor academic outcomes. However, few studies have focused on identifying moderating variables of academic performance specific to adolescents, especially those with ADHD. The current study seeks to address these limitations, further exploring moderators of academic outcomes in a clinical sample of adolescents with ADHD. Specifically, the present study examined adolescent ratings of routines, parent-adolescent conflict, perceptions of parental involvement, and school engagement, on the relationship between ADHD symptom severity and academic performance (GPA). The sample consisted of a total of 140 caregiver-adolescent dyads ranging from ages 11- to …

Population and Public Health Science Faculty Publications

Despite the widespread use of the expression “physical activity pattern” (PAP), there apparently is no general consensus regarding its definition. This systematic review aimed to examine available research focussing on (1) definitions of PAP, (2) instruments/techniques used to describe PAP, (3) statistical approaches used to analyse PAP, and (4) implications of PAP on children’s health. A systematic review of the available literature was done to identify studies published up to October 2019, and 76 studies were eligible. None of the studies presented a formal definition of PAP; a wide range of instruments were used to investigate children’s PAP, and most …

The Effects Of Alcohol Consumption On Cardiometabolic Health Outcomes Following Weight Loss In Premenopausal Women With Obesity: A Pilot Randomized Controlled Trial, John W. Apolzan, Robbie A. Beyl, Corby K. Martin, Frank L. Greenway, Ursula White

Clinical Research Faculty Publications

Alcohol (i.e., ethanol) is consumed regularly by much of the adult population; yet, the health effects associated with its use are not well-characterized. Clinical interventions to investigate the effects of moderate alcohol consumption on metabolic outcomes, including adiposity and cardiovascular risk factors, are limited and have yielded conflicting data. In addition, no study has reported the effects of routine alcohol intake during weight loss in a controlled feeding trial. We present the first randomized controlled pilot trial to investigate the effects of moderate alcohol consumption on metabolic outcomes during weight loss in women with obesity. Both groups consumed 30% energy …
