Can Temporary Signs Remind Who Should Yield At Uncontrolled Intersections? – A Driving Simulator Study, Kirti Mahajan, Saumik Sakib Bin Masud, Grace Savoie, Alexandra Kondyli

Kentucky Transportation Center Presentations

Background: A generic right of way (ROW) rule at uncontrolled intersections is to yield to the vehicle from the right, if not stated otherwise in the right-hand side driving countries such as the US. However, this rule is greatly neglected in practice, resulting in unsafe situations. This study investigated the effectiveness of using two proposed temporary yield signs: “Yield to Traffic on right” (Sign1_YT) and “Yield to Person on right” (Sign2_YP), to remind the drivers of ROW rule at uncontrolled intersections. Method: A driving simulator experiment was conducted with 20 drivers (aged 18-65 years), 50% males, recording observations for 198 …

Covid-19 And Access To Healthcare At The Crossing Of Race, Poverty, And Rurality, Shavonnie R. Carthens

Law Faculty Scholarly Articles

Black Americans make up 7.7 percent of the rural population in the United States. During the COVID-19 pandemic many in this population found themselves at a unique intersection of inequity - being Black, poor, and residing in a rural area. Poverty is a known contributor to negative health outcomes and is a risk factor for death from coronavirus infection. The association between race and poverty, when examining infectivity and mortality rates of COVID-19, have disproportionately devastated Black Americans and other minorities. Further, research indicates the presence of a general “rural mortality penalty” wherein rural Black communities have higher death rates …

The Fourth Estate's Estate, Ramsi Woodcock

Law Faculty Scholarly Articles

The news industry in the United States faces a funding crisis because the tech giants, particularly Google and Facebook, have acceded to the advertising monopolies once enjoyed by the newspaper industry itself. Breakup of these monopolies is unlikely to restore the news industry’s profits, however, because search and social media will remain better ad distribution channels than the news whether search and social media are competitive or monopolized. A better solution to the funding crisis would be for government to divide the advertising distribution market, reallocating to the news industry some of the ad impressions taken from it by the …

Multi-Jurisdictional Hazard Mitigation Plan For Landslides For The Big Sandy Area Development District, Kentucky, Matt M. Crawford, Hudson J. Koch, Jason M. Dortch

Contract Reports--KGS

Landslides are a complex geologic hazard that occurs worldwide, impacting lives, infrastructure, and property. The Big Sandy Area Development District, Kentucky incurs high landslide activity impacting several municipalities. This hazard mitigation planning project includes landslide susceptibility and risk assessments for the Big Sandy Area Development District. We based the landslide susceptibility model on statistics of hillslope morphological features such as slope, curvature, roughness, aspect, and elevation. Using a dual machine learning approach, we modeled the probability of landslide occurrence, defined as an area that is occupied, or might be occupied in the future, by a landslide. We also developed the …

Digital Footprints: Freedom On The Move At The University Of Kentucky, Vanessa Holden, Reinette F. Jones, Jennifer A. Bartlett, Kopana Terry

Library Presentations

During the late 18th through the mid-19th centuries, the Commonwealth of Kentucky saw significant movement of self-emancipated people seeking freedom from bondage. Often referred to as “runaways” or “fugitive slaves,” in historical texts, self-emancipated people defined freedom in many ways. These migrations were widely documented in newspaper advertisements known as fugitive slave advertisements and runaway ads in local newspapers published throughout the state. Access to these materials (often buried in databases or on microform) has been problematic at best. Enter the Self Emancipated and Enslaved People in Kentucky (SEEK) Project, a partnership between faculty in the University of Kentucky Libraries …

An Exploration Of Affective Influences Of Mediation And Instructional Delivery Styles In The U.S. Adult Media Literacy Learning Context, Joe Huber

Theses and Dissertations--Communication

This dissertation explores how varied delivery strategies may influence college student affective learning in a mediated setting. I employed a hybrid-grounded approach to the exploration of student-participant interviews wherein student-participants engaged with one of two online media literacy learning modules. The results of this study illustrate that students at varying points of their epistemological development (Perry, 1968) may face different affective hurdles depending on how media literacy curriculum is presented. We may anticipate that: (1) students who are less epistemologically developed (those featuring dualistic attitudes) may struggle to receive content, especially in the case where a teacher-centric delivery-style is employed; …

"Spreading Inoculation": The Effects Of Direct And Indirect Inoculation And Postinoculation Talk (Pit) On Graduate Students' Sense Of Belonging And Social Network Development During Socialization, Amanda Ruth Slone

Theses and Dissertations--Communication

During their first semester in graduate school, graduate students, many of whom are also employees of the university (BLS, 2019), encounter multiple challenges to successful socialization (Council of Graduate Schools, 2010; Weidman et al., 2001) —several of which are related to their sense of belonging (O’Meara et al., 2017; Pascale, 2018) — and if left unaddressed, these challenges can contribute to high attrition rates (Cassuto, 2013; Gardner & Barker, 2020), with one in four graduate students typically failing to graduate within ten years, even under favorable circumstances (Baum & Steele, 2017). Since the best time to influence an individual’s sense …

The Effects Of Controlling Language And Source Social Group Membership On Resistance To Persuasion, Zane A. Dayton

Theses and Dissertations--Communication

Persuasive attempts often fail. One theory that attempts to explain when and why people resist persuasion is psychological reactance theory (PRT; J. W. Brehm, 1966; S. S. Brehm & J. W. Brehm, 1981). According to the theory, people have an inherent desire to maintain their autonomy, or freedom. When they perceive that a persuasive message threatens their freedom, they experience psychological reactance, an aversive motivational state, which motivates them to restore their freedom by resisting the persuasive message. Whereas past studies have demonstrated that various message features (e.g., controlling language) and source characteristics (e.g., social group membership) can, individually, influence …

Biodegradable Nanoparticles Targeting Circulating Immune Cells Reduce Central And Peripheral Sensitization To Alleviate Neuropathic Pain Following Spinal Cord Injury., Michael N. Saunders, Kate V. Griffin, Irina Kalashnikova, Daniel Kolpek, Dominique R. Smith, Eiji Saito, Brian J. Cummings, Aileen J. Anderson, Lonnie D. Shea, Jonghyuck Park

Pharmaceutical Sciences Faculty Publications

Neuropathic pain is a critical source of comorbidity following spinal cord injury (SCI) that can be exacerbated by immune-mediated pathologies in the central and peripheral nervous systems. In this article, we investigate whether drug-free, biodegradable, poly(lactide- co -glycolide) (PLG) nanoparticle treatment mitigates the development of post-SCI neuropathic pain in female mice. Our results show that acute treatment with PLG nanoparticles following thoracic SCI significantly reduces tactile and cold hypersensitivity scores in a durable fashion. Nanoparticles primarily reduce peripheral immune-mediated mechanisms of neuropathic pain, including neuropathic pain-associated gene transcript frequency, transient receptor potential ankyrin 1 nociceptor expression, and MCP-1 (CCL2) chemokine …

ackground Gut microbiome metabolites are important modulators of host health and disease. However, the overall metabolic potential of the gut microbiome and interactions with the host organs have been underexplored. Results Using stable isotope resolved metabolomics (SIRM) in mice orally gavaged with 13 C-inulin (a tracer), we first observed dynamic enrichment of 13 C-metabolites in cecum contents in the amino acids and short-chain fatty acid metabolism pathways. 13 C labeled metabolites were subsequently profiled comparatively in plasma, liver, brain, and skeletal muscle collected at 6, 12, and 24 h after the tracer administration. Organ-specific and time-dependent 13 C metabolite enrichments …

Underground Blast Fragmentation Modeling For Use In The Mine-To-Mill Strategy, Lauren Shields

Theses and Dissertations--Mining Engineering

More than 40 years ago, the mine-to-mill concept was introduced in the mining industry by establishing a relationship or link between processing and mining activities. To date, many successful case studies have documented the evident benefits of the mine-to-mill approach. In most cases, the basis of the mine-to-mill approach is to tailor the details of a blast design and its proper execution in order to satisfy specific mineral processing requirements downstream. Most of the available literature and case studies deal with surface mine operations. Due to the relative simplicity of surface mining, the relationship between the powder factor, defined as …

Identifying Public Perceptions Towards Precision Dairy Technology Use, Brad Kelly

Theses and Dissertations--Animal and Food Sciences

To remain sustainable, the dairy industry must demonstrate commitment to addressing concerns from the public, such as sustainability and animal welfare. Precision dairy technologies (PDT) are a potential solution to ameliorate this issue, but public perceptions towards PDT are currently underinvestigated. This thesis aims to describe public perceptions towards PDT. Specifically, the objectives are to 1) describe baseline perceptions of the U.S. public towards PDT, 2) determine the effects of framing information about human-animal bond, data transparency, and animal welfare on PDT perceptions, and 3) evaluate how demographic characteristics mediate these perceptions. An online survey was used to measure baseline …

Contrary to previous empirical studies from other countries, my findings reveal no significant interdependence in spending among South Korean municipalities, …

How Black Undergraduate Students Experience Whiteness In Postsecondary Education, Karen Margaret Guettler-James

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

Critical whiteness scholars have described whiteness as a system of oppression that privileges White identities above others and perpetuates White supremacy. On the college campus, institutional, social, and historical norms reinforce the educational status quo and work together to maintain a system of whiteness that marginalizes Black students. This study investigated perceptions of whiteness held by student participants who self-identify as Black undergraduate students. Through focus group interviews, participants were asked to share their lived experiences with whiteness on the college campus. With the words of the participants, I reveal how campus standards that align with White Eurocentric norms devalue …

Exploring The Therapeutic Relationship In Mental Health Therapy With Queer And Disabled Adults, Rachel Womack

Theses and Dissertations--Social Work

Queerness and disability have been shown to be intimately connected, with members of the LGBTQIA+ community significantly more likely to identify as disabled compared to the general population. Though there are roughly 3-5 million queer and disabled individuals living in the United States, this remains a multiply marginalized and understudied population. Owing partially to stigma, minority stress, and discrimination, these individuals face an increased risk of a variety of mental health problems including depression, anxiety, self-harm, PTSD, and suicidality. Additionally, several barriers to mental health treatment exist, including inaccessible services, lack of provider knowledge, and outright discrimination from providers. Though …
