Theses and Dissertations--Plant and Soil Sciences

This thesis includes two main parts:

I. Evaluation of techniques for oil (total lipid) quantification of chia and soybean seeds.

This study evaluated ten different methods of seed oil quantification, including some methods that have not been applied to oilseeds before. The main aim of this study was to find one or more techniques that are easy, inexpensive, safe and fast with a small amount of ground seeds. The Soxhlet method was used as a standard to compared between techniques of oil quantification. The oil extraction by the Soxhlet method was evaluated with two solvents petroleum ether and acetone. There …

Dimensionality Analysis Of The Pals Classroom Goal Orientation Scales, Angela K. Tombari

Theses and Dissertations--Educational, School, and Counseling Psychology

Achievement goal theory is one of the most broadly accepted theoretical paradigms in educational psychology with over 35 years of influencing research and educational practice. The longstanding use of this construct has led to two consequences of importance for this research: 1) many different dimensionality representations have been debated, and 2) methods used to confirm dimensionality of the scales have been supplanted from best practice. A further issue is that goal orientations are used to inform classroom practice, whereas most measurement studies focus on the structure of the personal goal orientation scales rather than the classroom level structure. This study …

Development And Formative Evaluation Of The Speak7 African American Child Sexual Abuse Prevention Program, Mikeiya Y. Morrow

Theses and Dissertations--Educational, School, and Counseling Psychology

Child sexual abuse (CSA) is a complex issue among African American children, who experience significantly higher rates of CSA (Sedlak et al., 2012). Despite this, a dearth of research has examined CSA prevention among African American children. Moreover, there are no established culturally sensitive prevention programs targeted at addressing CSA among this demographic. This study addressed a significant gap in the literature by developing and evaluating the Speak7 African American Child Sexual Abuse Prevention Program (Speak7). Speak7 is a culturally sensitive, adult-focused CSA prevention program that aims to enhance the CSA prevention competence of adults who provide for African American …

Examining Substance-Use Treatment Utilization Among Incarcerated Women In Central Appalachian Jails, Rae Lyn Glover

Theses and Dissertations--Educational, School, and Counseling Psychology

Women in Central Appalachia represent a significant proportion of those engaging in problematic patterns of opioid use, which is concerning given the limited available services in the region and gender specific treatment barriers. This investigation seeks to understand the role of mental health and substance use symptoms among incarcerated Central Appalachian women and build on the conceptual model of substance use treatment utilization purposed by Leukefeld and colleagues (1998). Data for this study was drawn from a larger longitudinal investigation (NIDA 1R01-DA033866) and baseline data collected during initial interviews was analyzed. The sample included 400 women incarcerated at one of …

The Relationship Among Acculturation Orientation, Perceived Discrimination, Psychological Functioning And Gender Among South Asian And South East Asian International Students In The United States Of America, Dia Mason

Theses and Dissertations--Educational, School, and Counseling Psychology

The acculturation process for international students is influenced by several factors such as experiences of discrimination, economic condition, language fluency, and social support. Discrimination, which refers to negative or prejudicial behavior towards an individual or a group of individuals, takes place towards international students due to their poor grasp of the English Language (Lee & Rice, 2007), cultural differences (Cole & Ahmadi, 2003), and racial differences (Hanassab, 2006). Perceived discrimination (among other factors) has been identified as a potential moderator of the relationship between acculturation preferences and psychological functioning in acculturation theory (Berry, 2003). Apart from perceived discrimination, gender has …

Pill Poppin’ Nation: Substance Use, Mental Health, And Treatment Among Criminal Justice-Involved African Americans, Joi-Sheree' P. Knighton

Theses and Dissertations--Educational, School, and Counseling Psychology

The purpose of this dissertation was to examine substance use-related outcomes among criminal justice-involved African Americans using a multiple manuscript format. The Centers for Disease Control and Prevention has deemed nonmedical prescription opioid use an epidemic. National estimates indicate approximately 3.9% of African Americans engage in nonmedical prescription opioid use. Research suggests African Americans involved in the criminal justice system may be significantly at risk of substance use more generally; yet, there are no known estimates of nonmedical opioid use among this subgroup. Rising rates of nonmedical opioid use also has implications for discussing barriers to treatment among socioeconomically marginalized …

Examining Racism And White Allyship Among Counseling Psychologists, Kathryn H. Owen

Theses and Dissertations--Educational, School, and Counseling Psychology

Historically, research has focused on White individuals’ initial responses to learning about White privilege and other indicators of early stages of racial awareness and identity development. However, the literature is relatively sparse regarding understanding the experiences of racial identity development in White individuals who are beyond initial introductions to racial awareness, such as Counseling Psychologists (CPs). The assumption is that Counseling Psychology professionals are adequately trained to provide efficacious mental health services and engage in culturally sensitive work activities; however, research indicates that Black clients, colleagues, and graduate students experience racism, such as microaggressions, when interacting with White CPs.

Teaching Social Skills To Individuals With Comorbid Down Syndrome And Autism Spectrum Disorder: A Single-Subject Design Study, Matthew A. Cody Davis

Theses and Dissertations--Educational, School, and Counseling Psychology

Social skills are important for building and maintaining relationships, effective communication, and providing appropriate responses within social contexts. Deficits in social skills are often exhibited in individuals with comorbid Down syndrome (DS) and autism spectrum disorder (ASD). Peer-delivered interventions and other behavioral techniques for teaching specific social skills show effectiveness; however, the paucity of intervention research including individuals with DS-ASD has resulted in little guidance for how best to teach social skills and ensure generalization and maintenance. In the present study, a multiple probe study across behaviors, replicated across participants, assessed the effectiveness of peer-delivered simultaneous prompting in teaching socials …

“I Wonder What You Think Of Me”: A Qualitative Approach To Examining Stereotype Awareness In Appalachian Students, Chelsea G. Adams

Theses and Dissertations--Educational, School, and Counseling Psychology

Historically, Appalachia has been stereotyped as being a culture bred in poverty and ignorance. Much research has shown that stereotyping reveals a pattern of behavioral change and an impact on psychological well-being for the stereotyped (e.g., Pinel, 1999; Woodcock, Jernandez, Estrada, & Schultz, 2012), and has largely been centered on race and gender (e.g., Byrnes, 2008; Tuckman & Monetti, 2011). Less is known about the development of culture-specific stereotypes such as those related to Appalachians – a highly stigmatized group (Daniels, 2014; Otto, 2002). The purpose of this study was to gain an understanding of how adolescents in rural Appalachia …

Environmental Values, Stated Preferences, And Hypothetical Bias, Jerrod M. Penn

Theses and Dissertations--Agricultural Economics

Contingent Valuation (CV) methods are a primary tool in environmental economics to ascertain non-use or other values not observable through existing market mechanisms. Because common CV approaches typically rely on hypothetical answers from surveys in order to generate welfare estimates, these are often labelled stated preferences. Results from stated preference methods often diverge from those obtained when actual preference or behavior are involved. This divergence is commonly known as Hypothetical Bias (HB). This dissertation addresses HB as it applies to environmental applications. To begin, a meta-analysis using a sample of studies many times larger than previous works was performed. Its …

An Experimental Investigation Of The Effects Of Self-Compassion And Self-Criticism On Implicit Associations With Non-Suicidal Self-Injury, Laura M. Nagy

Theses and Dissertations--Psychology

Non-suicidal self-injury (NSSI) is the intentional destruction of bodily tissue in the absence of suicidal motives. NSSI is strongly associated with self-criticism (Gilbert et al., 2010) and individuals who self-injure often report doing so to punish themselves. Conversely, self-compassion, or the tendency to be caring with oneself, is associated with psychological well-being (Neff et al., 2007). The aim of the present study was to determine whether experimentally inducing self-criticism or self-compassion would lead to changes in implicit identification with NSSI. The Self-Injury Implicit Association Test (SI-IAT; Nock & Banaji, 2007) is an assessment of the strength of the automatic associations …

Sexy, Thin, And White: The Intersection Of Sexualization, Body Type, And Race On Stereotypes About Women And Women's Body Dissatisfaction, Ellen A. Stone

Theses and Dissertations--Psychology

The vast majority of media images present one idealized type of woman: she is thin, sexualized, and White. While research has shown that there are stereotypes associated with sexualized women, research has not addressed whether these stereotypes vary based on other characteristics such as body type and race. The current study aimed to examine the stereotypes associated with women who varied in body size, sexualization, and race. Additionally, the current study examined whether exposure to differing portrayals of women was related to endorsement of gender stereotypes and body dissatisfaction. College-aged students (n = 226, 161 women) rated four traits …

Comparing The Effects Of Mindfulness Meditation And Relaxation In A Brief Laboratory Induction, Carolina A. Caldera

Theses and Dissertations--Psychology

Mindfulness is the practice of being nonjudgmentally aware of the present moment. Researchers often study the effects of mindfulness using brief laboratory-based mindfulness inductions in which participants are guided through mindfulness exercises, after which outcome measures are examined. However, most studies have not assessed whether participants achieved a mindful state during the induction, or whether the effects of mindfulness inductions differ from the effects of similar procedures such as relaxation. The present study compared a mindfulness exercise to a relaxation exercise and a control condition. After the induction, participants completed measures of the extent to which they attained a mindful …

Are Cultures Of Honor Our True Protectors?, Brian Enjaian

Theses and Dissertations--Psychology

Men from a culture of honor often use physical aggression in response to threats as a way of restoring lost honor. These threats can range from being called an offensive name to someone flirting with their romantic partner. However, cultures of honor form to protect society against threats. Once society no longer needs protection, cultures of honor dissipate. In three studies, the protective qualities of a culture of honor were examined by comparing aggression levels when romantically attached men were threatened to when their significant other was threatened. Study 1 (N=114) consisted of hypothetical scenarios while Study 2 (N=260) and …

Testing A Values-Based Approach To Healthcare Decision-Making In Older Adults, Paul Jefferson Geiger

Theses and Dissertations--Psychology

Despite natural declines in physical and cognitive function, older adults maintain good emotion regulation abilities, leading to emotional wellbeing and resilience. This phenomenon can partially be explained by socioemotional selectivity theory (SST), which posits that when time is perceived as a limited resource, older adults focus attention on positive environmental stimuli to regulate emotions. Although this positivity effect maintains emotional wellbeing, it may disrupt information processing related to healthcare decision-making. Older adults request less information from their doctors, are less likely to ask for a second opinion, make their decisions more quickly, and devote more attention to positive medical information, …

Personality And Learning Predictors Of Adolescent Alcohol Consumption Trajectories, Sarah J. Peterson

Theses and Dissertations--Psychology

In a sample of 1897 youth studied across the last year of elementary school to the second year of high school, we (a) characterized different developmental trajectories of drinking frequency and drinking-related problems and (b) tested an a priori risk model that predicted variation in trajectory group membership. Analyses revealed five separate trajectories for both drinking frequency and drinking problems. Wave 1 scores on impulsigenic traits, expectancies for the reinforcing and stimulating effects of alcohol, and early pubertal onset differentiated among the trajectory groups, in some cases before the groups differed in drinking behavior. We also found substantial covariation between …

Behavioral Deficits Across Development In A Novel Mouse Model Of Fetal Ethanol Effects, Andrew B. Hawkey

Theses and Dissertations--Psychology

Fetal Alcohol Spectrum Disorders (FASD) are a spectrum of anatomical, developmental and neurobehavioral impairments resulting from ethanol (ETOH) exposure during fetal development. Efforts to develop and screen novel pharmacotherapies against fetal ETOH effects depend heavily upon rodent models to provide indicators of the safety and efficacy of such compounds, in addition to helping better understand the underlying mechanisms to develop and test these pharmacotherapies. The following experiments describe the development of a novel mouse model of FASD using behavioral batteries to assess behavioral or cognitive deficits in juvenile and adolescent offspring (Experiment 1, Experiment 2) and whether deficits with this …

Too Pretty For Homework: The Academic Correlates Of Sexualized Gender Stereotypes Among Adolescent Girls, Andrew A. Nelson

Theses and Dissertations--Psychology

Girls grow up in a culture of ubiquitous female sexualization, and this culture propagates stereotypes that could interfere with their academic outcomes. The current study examined the academic correlates of these sexualized gender stereotypes (SGS) among early adolescent girls. Girls (N = 99) aged 11 to 14 (M_age = 12.4 years, SD = .57 years) completed a survey assessing their academic performance, attitudes, and beliefs. The survey also assessed the degree to which girls believed that boys and girls should act in accordance with these sexualized gender stereotypes. Results indicated that higher endorsement of sexualized gender stereotypes …

Usability Is Not Just Usability: Discovering The Strategies Used By Non-Experts In Making Usability Predictions, Michelle A. Sublette

Theses and Dissertations--Psychology

Much of the research on metacognition in human factors has focused on prescriptive, normative strategy training. That is, many researchers have concentrated their efforts on finding ways to improve system users’ prediction, planning, monitoring and evaluation strategies for tasks. However little research has focused on the strategies and heuristics users employ on their own to make usability predictions. Understanding usability prediction methods is critical because users’ predictions inform their expectations about whether they will make errors using a product, how much effort they will need to expend to be successful in using the product, whether they can perform two tasks …

Dismantling The Five Factor Form, Stephanie L. Rojas

Theses and Dissertations--Psychology

The purpose of this dissertation was to provide a further validation of the Five Factor Form (FFF; Rojas & Widiger, 2014). The FFF is a brief (one page) rating form that assesses for adaptive and maladaptive variants of both poles for each of six facets for the five domains of the five-factor model. Two prior validation studies of the FFF have been completed using the items as they are scored within the FFF (Rojas & Widiger, 2014, in press). However, the FFF has a unique scoring system in which each item has normal and abnormal variants at both poles (e.g., …

Maintenance Of Positive Affect Following Pain In Younger And Older Adults, Ian Andres Boggero

Theses and Dissertations--Psychology

Socioemotional selectivity theory posits that as people age, they become motivated and successful at maximizing positive emotions and minimizing negative ones. Yet, 70% of older adults report physical pain, which is associated with negative affect. The strategies and resources that older adults use to maintain positive affect in the face of pain remain largely unknown. Specific positivity-enhancing strategies include recalling, recognizing, and responding to positive stimuli and prioritizing close over knowledgeable social partners. Executive functions (EF, i.e., task-switching, working memory, and inhibition) and heart rate variability (HRV) may be important resources for coping with pain. The current project used two …

The Influence Of Cocaine-Related Images On Inhibitory Control In Cocaine Users, Erika Pike

Theses and Dissertations--Psychology

Cocaine users display impaired inhibitory control. The influence of cocaine-related stimuli on inhibitory control has not been assessed. The Attentional Bias-Behavioral Activation (ABBA) task uses cocaine and neutral images as cues to determine if drug-related images impair inhibitory control in cocaine users. This dissertation was designed to assess the influence of cocaine images on inhibitory control in cocaine users through the conduct of studies designed to address four aims. The first aim was to demonstrate that cocaine users display impaired inhibitory control following cocaine images compared to neutral images on the ABBA task. This was accomplished through the conduct of …

God On Trial: Are Our Moral Judgments Different Based On Whether We Are Judging God Or Humans?, Ben Kok Leong Ng

Theses and Dissertations--Psychology

Past work in moral psychology has demonstrated that individuals’ judgments of other humans in hypothetical moral scenarios can be influenced by variables such as intentionality, causality and controllability. However, while empirical studies suggest that individuals similarly hold nonhuman agents such as robots morally accountable for their actions to the extent that they are perceived to possess humanlike attributes important for moral judgments, research is scant when God is introduced as a nonhuman agent. On one hand it is proposed that because people anthropomorphize God, our moral intuitions of humans and God tend to show similar effects. In this case, both …

Optimism And Pain Interference In Aging Women, Stephanie T. Judge

Theses and Dissertations--Psychology

Pain interferes with people's daily lives and often limits the extent to which they can pursue goals and engages in activities that promote well-being. The present study test how optimism affects and is affected by pain interference and activity among older women. Every three months for two years, middle- and older-age women (N = 199) complete daily diaries at home for a seven-day period, reporting their daily pain, pain interference, and activity. Optimism was measured at baseline and end-of-study. Multilevel models test the between- and within-person relationships among pain, optimism, pain interference and activity. Pain best predicted pain interference …

Risk Factors For Abuse Of Prescription Stimulants In College Students: A Dissertation, Eric A. Haak

Theses and Dissertations--Psychology

The abuse of prescription stimulants among college students is a growing public health concern. While these substances are often viewed as safe, “smart drugs”, they are associated with a number of maladaptive outcomes, ranging from poorer academic performance to cardiovascular incidents and even death. To date, the majority of research on the abuse of these substances have focused on demographic factors which are not amenable to intervention, such as race, Greek organization status, and class rank. The current study examined family factors, academic stress, and impulsivity as potential risk factors which are amenable to intervention. In a sample of 335 …

Caars-S:L Infrequency Index Validation: A Pilot Comparison Of Paper And Online Assessments, Elizabeth R. Wallace

Theses and Dissertations--Psychology

One obstacle to the accurate diagnosis of ADHD in college students is malingering, although many symptom self-report measures do not contain feigning validity scales. The Infrequency Index (CII) for the Conners’ Adult ADHD Rating Scale–Self-Report: Long Version (CAARS-S:L) was developed for this purpose, although further validation of the index is needed. Another topic of interest in ADHD malingering research is the increasing use of online assessments. Little is known about how ADHD is malingered in an online format, particularly on the CAARS-S:L. The current study aims to integrate these strands of research by examining the utility of the CII in …

Beyond The Coal Divide: The Cultural Politics Of Natural Resource Extraction In Central Appalachia, Julie A. Shepherd-Powell

Theses and Dissertations--Anthropology

During the last several years far southwest Virginia, like elsewhere in the central Appalachian region, has faced a decline in all coal mining activity and a subsequent loss of coal mining jobs, meaning that local economies are suffering and the unemployment line is long. In addition, this area continues to face environmental pollution from surface coal mines that are still in operation or have not been reclaimed. Drawing upon anthropological literature on natural resource extraction and economic and environmental inequality, this dissertation highlights the lives of members of a local grassroots environmental organization, as well as other local residents, in …

Reproducing Childbirth: Negotiated Maternal Health Practices In Rural Yucatan, Veronica Miranda

Theses and Dissertations--Anthropology

This ethnographically informed dissertation focuses on the ways rural Yucatec Maya women, midwives and state health care workers participate in the production of childbirth and maternal health care practices. It further addresses how state health programs influence the relationships and interactions between these groups. Although childbirth practices in Yucatan have always been characterized by contestation, negotiation and change, their intensity and speed have significantly increased over the last decade. Drastic changes in the maternal health of rural indigenous communities in Mexico and throughout the world are directly connected to intensified state interventions that favor biomedicine over traditional health systems. In …

Partner Influence In Diet And Exercise Behaviors: Testing Behavior Modeling, Social Control, And Normative Body Size, Brea Perry, Gabriele Ciciurkaite, Christy Freadreacea Brady, Justin Garcia

Sociology Faculty Publications

Previous research has documented social contagion in obesity and related health behaviors, but less is known about the social processes underlying these patterns. Focusing on married or cohabitating couples, we simultaneously explore three potential social mechanisms influencing obesity: normative body size, social control, and behavior modeling. We analyze the association between partner characteristics and the obesity-related health behaviors of focal respondents, comparing the effects of partners’ body type, partners’ attempts to manage respondents’ eating behaviors, and partners’ own health behaviors on respondents’ health behaviors (physical activity, fruit and vegetable consumption, and fast food consumption). Data on 215 partners are extracted …

Regular Expressions In Practice, Kathryn Lybarger

Library Presentations

Regular expressions are not just for programmers anymore; they are supported by common software and systems used for cataloging and metadata, and allow for very powerful search and replace, even complete reformatting of library data! In this webinar, we’ll discuss the building blocks of regular expressions, practice identifying what they match (and do not match!), and consider how we can use them to make everyday library work more efficient.
