Restructuring Work “The Chattanooga Way”: Urban Revitalization, Contingent Labor, And Trying To Get By In Tennessee, Mauri Systo

Theses and Dissertations--Anthropology

In Chattanooga, TN, the construction of a fiber optic telecommunications network has led to a tech-based revitalization strategy, and the promotion of entrepreneurial and technical positions within the Downtown. This dissertation questions what revitalization, the “Chattanooga Way,” means to differently situated residents of Chattanooga, TN, and how those differences in interpretation are related to lived experiences of economic inequality. Powerful local discourses, like the Chattanooga Way policy model and its accompanying “origin myth” of Chattanooga’s development often conceal disparities between grass-roots, public, and private sector notions of economic revitalization. Through the projection of a tech-based economic future, Chattanooga has created …

Carceral Extractivism, Livelihood Strategies, And “Acting Right” In The U.S. South, Edward L. Bullock

Theses and Dissertations--Anthropology

Mass incarceration and its effects are well documented and carceral privatization is hotly contested on moral and economic grounds. This dissertation examines the local effects of carceral privatization in the U.S. south in historical context. Tallulah is a small, rural predominately African American town in northeastern Louisiana that endures high rates of poverty, unemployment, and low educational attainment. It also hosts four private prisons operated by LaSalle Corrections, LLC. Two primary and overlapping questions guide the research. 1) How has an history of carceral entrepreneurship and mass incarceration impacted the way persons and communities create livelihoods and imagine futures, and …

We Died And Were Reborn: An Anthropological Study Of Health-Seeking Strategies For Mental And Emotional Distress In Post-War Eastern Sri Lanka, Daniel Ball

Theses and Dissertations--Anthropology

Since the early 2000s, Sri Lanka has made major gains in decentralizing and expanding state-based mental healthcare access and services outside of Colombo. However, little evidence exists related to on-the-ground experiences of Sri Lankans who access these services, the quality and sustainability of services, and the effects services have on individual therapy management of mental and emotional distress. In addition to an extensive historical review of mental health service provision, this dissertation explores strategic health-seeking practices among Tamil-speaking communities in eastern Sri Lanka—an area ravaged by high rates of poverty, 26 years of civil war, and the 2004 tsunami catastrophe. …

Beyond Extractivism And Governmentality: The Postneoliberal State, Development, And The Circulation Of Oil Rents Among Indigenous Peoples In The Ecuadorian Amazon, Karla Monserrath Encalada-Falconí

Theses and Dissertations--Anthropology

This dissertation explores the experiences of an indigenous community from the Northern Ecuadorian Amazon during the implementation of extractivism, development, and redistributive projects. Drawing on twenty months of ethnographic fieldwork in the community of Playas del Cuyabeno and in Quito, the capital of Ecuador, I question the common assumption that indigenous peoples radically reject extractivism and state-imposed modernizing agendas. In contrast, this study shows how indigenous peoples negotiate resource extraction in their territories and navigate the partial failures of postneoliberal redistribution and the contradictory agendas of economic development projects—specifically the aim of the postneoliberal Ecuadorian government’s project to redistribute rents …

What Contributes To High Adolescent Pregnancy Rates In Ecuador? A Secondary Analysis Of A Qualitative Study, Isabel D. Gollmar, Hartley C. Feld

Posters-at-the-Capitol Presentations

Introduction: Ecuador has the second highest rates of adolescent pregnancy in South America. Adolescent pregnancy is associated with negative health implications, including miscarriage, neonatal and maternal demise, cephalopelvic disproportion, and illness throughout infancy. Additionally, adolescent pregnancy perpetuates the cycle of poverty and is associated with lower educational attainment and increased reliance on social services.

Purpose: The purpose of this study was to describe experiences that contributed to unintended adolescent pregnancy of Ecuadorian women living in a low-resource community. Specifically, this work aimed to identify barriers to seeking or utilizing birth control in sexually active adolescents. The long-term goal of this …

The Differential Efects Of Hand-Raising And Digital Response Cards On Active Engagement Of High School Students With Mild To Moderate Disabilities During Literacy Activities, Meredith Davis

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

The purpose of the study was to investigate how both hand-raising and digital response cards effect student engagement, on-task behavior, and off-task behavior. Academic achievement was also assessed using a high-tech student responses system. An ABAB withdrawal design was used to evaluate the effects among high school students with mild to moderate disabilities during reading lessons. The results showed digital response cards increased active engagement for all participants, but digital response card conditions did not show increased levels of on-task behavior.

Using Coaching Strategies To Support Parents When Promoting Social Communication In Individuals With Disabilities, Molly Baldridge

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

The purpose of this practitioner’s piece was to provide educators with a research-based coaching model that will increase opportunities for meaningful collaboration with parents or guardians in order to promote family-centered and socially meaningful child outcomes for their children with autism or other intellectual disabilities. The training model was based on Lane et. al.’s (2016) brief coaching method approach. Other suggested components to parent training included cultural competency, goal setting, planning for generalization, following up and asking for feedback, and troubleshooting any problem behaviors.

[3 H]Dopamine Uptake Through The Dopamine And Norepinephrine Transporters Is Decreased In The Prefrontal Cortex Of Transgenic Mice Expressing Hiv-1 Transactivator Of Transcription Protein, Matthew J. Strauss, Bernadette O’Donovan, Yizhi Ma, Ziyu Xiao, Steven Lin, Michael T. Bardo, Pavel I. Ortinski, Jay P. Mclaughlin, Jun Zhu

Psychology Faculty Publications

Dysregulation of dopamine neurotransmission has been linked to the development of human immunodeficiency virus (HIV)-associated neurocognitive disorder (HAND). To investigate the mechanisms underlying this phenomenon, this study used an inducible HIV-1 transactivator of transcription (Tat) transgenic (iTat-tg) mouse model, which demonstrates brain-specific Tat expression induced by administration of doxycycline. We found that induction of Tat expression in the iTat-tg mice for either 7 or 14 days resulted in a decrease (∼30%) in the Vmax of [3 H] dopamine uptake via both the dopamine transporter (DAT) and norepinephrine transporter (NET) in the prefrontal cortex (PFC), which was comparable to the magnitude …

Effects Of Ethanol, Naltrexone, Nicotine And Varenicline In An Ethanol And Nicotine Co-Use Model In Sprague-Dawley Rats, Cassie M. Chandler, Sarah E. Maggio, Hui Peng, Kimberly Nixon, Michael T. Bardo

Psychology Faculty Publications

Background: As alcohol and nicotine use disorders are entwined, it may be possible to develop a single medication to treat both. We previously developed a model for ethanol (EtOH) and nicotine co-use in female selectively bred alcohol-preferring (P) rats. To model co-use in a genetically diverse population, we adapted the model to outbred Sprague-Dawley rats of both sexes and assessed the effect of drug pretreatments.

Methods: In phase 1, rats were trained in a 2-bottle choice between water and a sweetened or unsweetened EtOH solution in operant chambers. In phase 2, rats were trained in nicotine self-administration under an increasing …

Presence Of A Social Peer Enhances Acquisition Of Remifentanil Self- Administration In Male Rats, Rebecca S. Hofford, Paige N. Bond, Jonathan J. Chow, Michael T. Bardo

Psychology Faculty Publications

Background: Social peers influence human drug use at every stage of addiction. Using a dual-compartment apparatus that allows for limited social contact, recent work has shown that cocaine self-administration is enhanced when two rats are trained to self-administer at the same time compared to rats trained alone or trained in the presence of a saline self-administration control peer. The current study measured social influence on self-administration of the short-acting opioid remifentanil using a dual-compartment operant conditioning chamber.

Methods: Adult male rats were placed in one of five groups: (1) REMI-REMI group, in which both rats self-administered remifentanil; (2) REMI-SAL group, …

Methodological Considerations For The Determination Of The Critical Resistance For The Deadlift, Alexander C. Moss

Theses and Dissertations--Kinesiology and Health Promotion

This study determined if plate movement during conventional deadlifting affects critical resistance (CR) estimates derived from the linear work limit (W_lim) versus repetitions relationship. Eleven subjects completed 1-repetition maximum (1RM) deadlift testing followed by 8 visits, to determine the number of repetitions to failure at 50%, 60%, 70%, and 80% 1RM for both reset (RS) and touch-and-go (TG) methods, respectively. The CR was calculated as slope of the line of total work completed (repetitions × load [in kilograms]) versus total repetitions for each of four intensities (50-80% 1RM). The number of repetitions to failure were determined at CR …

Is Athlete Activism A Predictor Of Resilience?, Travis Robert Scheadler

Theses and Dissertations--Kinesiology and Health Promotion

Several athletes have taken personal responsibility to engage in activism, often with hopes of bringing social and political change. While scholars have identified several barriers preventing athletes from engaging in activism (e.g., public criticism, status and job loss, withdrawal of funding, anticipated distress; Cunningham & Regan, 2012), other scholars have identified personal benefits from engaging in activism (e.g., improved confidence, self-concept, belief in change, agency, life meaning; Klar & Kasser, 2009; Rabkin et al., 2019). Distress from the barriers, however, may be prerequisites to enhancing resilience, a theoretical construct that may help explain the benefits of activism. Thus, by applying …

Identifying And Predicting Intention To Quit Using Juul Among Emerging Adults, Jakob W. Hester

Theses and Dissertations--Kinesiology and Health Promotion

Objectives: (1) Describe intention to quit, (2) identify relationships between sociodemographic factors or social influences and intention to quit, (3) explore if Theory of Planned Behavior-informed constructs can predict intention to quit as well as identify which construct best predicts, and (4) discover if descriptive norms strengthen a predictive model of intention to quit among emerging adults currently using Juul. Participants: Full-time, first-year students currently using Juul, an e-cigarette product, at a large university in the southeastern United States (N = 182). Methods: A November 2018 online survey assessed sociodemographic characteristics, social influences, patterns of use, quit intention, and attitudes, …

Knee Joint Loading Following Anterior Cruciate Ligament Reconstruction: Link To Patient Reported Outcomes And A Novel Method To Monitor With Wearable Sensors, Alex Spencer

Theses and Dissertations--Kinesiology and Health Promotion

Recovery from anterior cruciate ligament reconstruction (ACLR) commonly results in undesirable physical and patient-reported outcomes (PROs). Identification of modifiable factors such as knee contact force (KCF) early in rehabilitation that can improve these outcomes is important due to the rapid decrease in function, quality of life, and joint health in this population. Additionally, if noninvasive measurement of KCFs outside of a traditional laboratory were possible, clinicians could optimize patient treatment with personalized care. Therefore, there are two primary aims to this thesis: 1) quantify the link between KCF and PROs which measure pain, ability to perform activities of daily living, …

Predictors Of Work Economy In Structural Firefighters, Maxwell Steele Norris

Theses and Dissertations--Kinesiology and Health Promotion

The purpose of this study was to investigate a novel work economy metric to quantify firefighter physical ability and identify physical fitness and anthropometric correlates of work economy. Physical fitness and anthropometric measurements were taken on 19 incumbent structural firefighters (Age: 35.0±7.1 yr, Body mass: 87.5±13.1 kg). Firefighters performed a timed maximal effort simulated fireground test (SFGT) in personal protective equipment. SFGT air depletion was represented by change in cylinder pressure. Work economy was quantified as: (1/(SFGT completion time x air depletion))x10⁴. Bivariate and multiple linear regression analyses were used to identify anthropometric and physical fitness predictors of …

A Systematic Review Of Mindfulness Interventions’ Impact On Athlete Emotional Distress & Wellbeing, Trevor Nathan Tierney

Theses and Dissertations--Kinesiology and Health Promotion

Mindfulness-based interventions’ (MBIs) effectiveness for improving wellbeing and reducing emotional distress is well-documented in both clinical and non-clinical sections of the general population (McAlarnen & Longshore, 2017). Although mindfulness has been shown to be effective with these populations, less is known about the specific effects for athletes. The effects of MBI’s for athletes may be different given that the intention for MBIs in the sport context is typically to improve performance, where in most other contexts it is not (Gardner & Moore, 2012). Furthermore, athletes are a distinct population who possess unique factors on which their wellbeing and mental health …

An Examination Of Sexual Fantasy And Infidelity, Katherine Rose Haus

Theses and Dissertations--Kinesiology and Health Promotion

Infidelity is a common behavior, influencing many people within romantic relationships (Mark & Haus, 2019). Many factors have been linked to increased infidelity engagement, but no studies exist documenting the role of sexual fantasy regarding infidelity. One such predictor of infidelity is need fulfillment, or the extent to which one’s needs are fulfilled in their relationship (Le & Agnew, 2001). Sexual fantasy is a highly common, but largely understudied sexual behavior (Lehmiller, 2018). Therefore, the aims of the current study were: 1) to document the role that sexual fantasy and need fulfillment play in infidelity, 2) to determine any potential …

Effects Of Relative Inertial Load On Performance Measures And Quadriceps Electromyography During Flywheel Resistance Training Squats, Jason Todd Brantley Jr.

Theses and Dissertations--Kinesiology and Health Promotion

Flywheel resistance training (FRT) has become an increasingly popular modality for exercising due to its unique application of providing external resistance. Little is known about how changes in relative inertial loads affects performance and electromyography (EMG) activity. The purpose of this study was to examine how performance metrics and quadriceps EMG activity are affected by relative inertial load during FRT-based squats. Fifteen resistance trained individuals completed five sets of five repetitions of squats with varying relative inertial loads in random order. Peak Eccentric Power (PEP), Peak Concentric Power (PCP), average force, total work, and repetition time were measured. Surface level …

Exploring Positive Identity And Relationship Satisfaction In Bisexual Women In Relationships With Men, Kamryn Michel

Theses and Dissertations--Kinesiology and Health Promotion

Bi-negative discrimination, negative attitudes, and beliefs regarding bisexual individuals are at least partially responsible for mental and physical distress in the bisexual community (Friedman et al., 2014). Romantic relationships can act as a buffer against negative health outcomes as well as increase overall well-being (Dush & Amato, 2005). However, research has shown that binegitive attitudes can impact a person’s willingness to begin relationships with bisexual individuals (Fienstein et al., 2014). This study aimed to explore the impact of positive identity on relationship satisfaction of bisexual women in relationships with men. In particular, we investigated five possible facets of positive identity: …

Health Priorities, Current Lifestyle Behaviors, And Barriers To A Healthy Lifestyle Among Emergency Department Nurses, Shannon C. White

Theses and Dissertations--Kinesiology and Health Promotion

Background: Emergency nurses are tasked with managing the hectic, unpredictable, and constantly changing environment of an ED. In addition, emergency nurses have been shown to have high levels of stress, irregular meal schedules, rotating shift work, long hours, and a lack of physical activity. Furthermore, research has suggested that nurses are at an increased risk for non-communicable diseases, such as diabetes, hypertension, and coronary heart disease (Phiri, et al., 2014), in addition to a high prevalence of obesity (Kyle, et al., 2016).

Methodology: In this study, 23 emergency nurses completed a 43-item survey regarding current behaviors and constructs of …

Application Of High Performance Training Strategies To Enhance Occupational Readiness In Law Enforcement Cadets, Gabriel Jose Martinez

Theses and Dissertations--Kinesiology and Health Promotion

Law enforcement requires cadets to achieve a requisite level of physical fitness to prepare for occupational demands. However, there is limited research on the effectiveness of academy exercise programs to optimize physical fitness and occupational physical ability through high performance training strategies more typically utilized in elite athletic populations. Furthermore, there is a paucity of research identifying physical fitness correlates of occupational performance. Collectively, this information will provide academies and practitioners with critical information to develop evidence-based training programs. Therefore, the purposes of this study were to: Aim 1) Examine the effectiveness of integrating autoregulatory progressive resistance exercise (APRE) and …

Can Precision Farming Technologies Be Applied To Grazing Management?, S. Mark Rutter

IGC Proceedings (1977-2023)

In arable farming, precision is used to monitor and manage crop variability. The same precision approach can be used to manage grassland, by using crop sensing, targeted fertilizer/herbicide/pesticide application and forage yield measurement when it is harvested mechanically. An additional challenge in grassland agriculture is developing precision approaches to manage the grazing process. This requires technologies to determine where an animal is, when, what and how much it is grazing which the system then needs to use in conjunction with other sources of information to control where the animal grazes next. This paper reviews the existing technologies in these …

Opportunities For Improving Livestock Production With E-Management Systems, Dave L. Swain, Rebecca N. Handcock, Greg J. Bishop-Hurley, Don Menzies

IGC Proceedings (1977-2023)

There is increased interest in hardware and software that can support e-Management for grassland-based livestock industries. Managers of grazing livestock were early adopters of radio frequency identification (RFID) technologies automatically monitoring individual animal performance. Recent developments of remote sensing, automated individual recording and management, location based systems, improved data transfer and technologies that can be used in more extensive grazing systems are providing new opportunities for the development of e-Management systems. There is a need for better data integration and systems that can provide the best available information to enable better decision-making. For greater industry adoption of more integrated e-Management …

Effect Of High Se And Co Alfalfa Forage On Animal Production, Xiao-Lei Jie, Xiao Guo, Hua-Feng Hu

IGC Proceedings (1977-2023)

Total and available selenium (Se) and cobalt (Co) concentrations are low in Chinese soils, especially those found in mainly in temperate humid sub-humid conditions in the northeast to the southwest band across China (Tan et al. 2002). The levels of Se and Co are marginally deficit in the brown soil of the Yellow River region which causes lower production level and quality in forage and crop plants. Application of Se and Co fertilizers to arable lands is essential to produce high Se and Co forages. Henan is a Province where produce high-quality grass forages are used to support dairy …

Fatty Acid Metabolism On Pasture- And Feedlot-Finished Cattle, Cuk T. Noviandi, Robert E. Ward, Jong-Su Eun, Dale R. Zobell, Rusty D. Stott, Blair L. Waldron, Mike D. Peel

IGC Proceedings (1977-2023)

Feeding high-grain diets to finishing beef cattle results in high proportions of saturated fatty acids (SFA) in the beef, which is considered to confer negative impacts on human health. In contrast, pasture-finished cattle produce lower proportion of SFA, greater n-3 and less n-6 polyunsaturated fatty acids (PUFA), and higher conjugated linoleic acids (CLA) compared to high grain-finished beef (Noviandi et al. 2012). Increased n-3 PUFA, especially C18:3 n-3, can reduce the risk of heart disease, hypertension, inflammation, and mammary cancer, and lower cholesterol concentration in blood (De Deckere et al. 1998; Tapiero et al. 2002).

Dietary Effect Of Substituting Panicum Maximum With Tithonia Diversifolia Forage On Performance Of Yankasa Sheep, Adebowale N. Fajemisin, Timayin Salihu, Akinyemi Fadiyimu, Adebayo Alokan, Olusola Agbede

IGC Proceedings (1977-2023)

Ruminant livestock production in Nigeria is based predominantly on native grassland (especially Panicum maximum); the nutritive value of the natural pasture varies drastically according to season (Ademosun.1992). Changes in nutritional status of these native plants result in very irregular growth and marked fluctuations in seasonal weights of farm animals. Consequently, it becomes imperative to source for alternative feed resources which are more efficient, economical and can be incorporated into ruminant’s diet with a view to reducing feed costs and hence, achieving a greater profit margin for the producer. Tithonia diversifolia is an herbaceous weed of field crops and is …

Developing And Implementing Animal Welfare Assessments On Extensive And Intensive Grassland Systems: An Overview, Nguyen Xuan Trach, Bob Kilgour

IGC Proceedings (1977-2023)

While several definitions of animal welfare exist, in this paper we use the concept of the Five Freedoms. The Five Freedoms are freedom from hunger, thirst and malnutrition; freedom from discomfort; freedom from pain, injury and disease; freedom from fear and distress; freedom to perform normal behavior. While the idea of the Five Freedoms has limitations, it is still a widely-used conceptualization of animal welfare and we use it here to discuss the welfare of cattle in intensive and extensive management systems in Vietnam and Australia. Compared to extensive pasture systems, intensive management systems do result in heightened animal welfare …

The Evolving Beef Industry And Its Sustainability In Western China, J. P. Wu, Z. M. Lei, L. P. Zhang, X. R. Wang, S. G. Zhao, C. Q. Zhang, G. H. Sun, S. G. Li

IGC Proceedings (1977-2023)

The beef industry in China has started to develop since the 1980s. Since then, its production system has been evolving significantly from subsistence production towards business operation in farmer households. As demands continue to grow, China will become the largest beef consumption country in the world by the year of 2025. The beef production in China’s western agriculture regions is gaining significant role in the beef industry of China. Utilization of corn stover and other agriculture aftermath is seen as the competitive advantage of development of the beef industry. Over the last 30 years the beef production efficiency has been …
