Participatory Research For Smallholder Livestock Systems: Applying Common Sense To Complex Problems, P. M. Horne, Werner Stür

IGC Proceedings (1977-2023)

Key Points:

1. Participatory approaches to research (PAR) bring researchers closer to farmers, the intended users of research outputs.

2. Active, functional participation of farmers in the evaluation and development of new technologies requires researchers to make an important commitment: respecting the knowledge, skills and opinions of farmers while maintaining confidence in their own scientific knowledge.

3. Farmer experimentation is not usually suitable to provide quantitative biophysical data (this can be achieved more effectively in researcher controlled experiments), but to provide qualitative information and improve understanding. This type of information can be collected systematically to enable rigorous analysis.

4. While …

Computer-Based Forage Management Tools: Historical, Current, And Future Applications, David B. Hannaway, C. Daly, D. F. Chapman, B. B. Baker, A. S. Cooper

IGC Proceedings (1977-2023)

Forage management has been an important human activity since the beginning of civilization. By comparison, the personal computer has been available only in the immediate past. The software developed to deal with the complexity of climate, soil, plant, animal, and socioeconomic factors has seen huge changes in a few decades. Mainframe computers facilitated numerical calculations for exploring relationships among dozens of variables. Personal computers opened the door for more individual scientist creativity and routine communication. Web-based communication globalised the option for multidisciplinary teams to tackle problems. Forage-related computer applications abound, allowing farmers, ranchers, and others to more effectively manage the …

Paying For Our Keep: Grasslands Decision Support In More-Developed Countries, Andrew D. Moore

IGC Proceedings (1977-2023)

“Models in grassland science have come to stay, and so they must be made to pay for their keep. To do that, it will be necessary to improve their scientific sophistication and their management relevance...” (Seligman, 1993).

Decision support (DS) tools in grassland agriculture have also come to stay. This review will examine the ways and means by which DS tools are being made to pay for their keep, with a focus upon DS efforts from the last decade and on the lessons that arise for those who develop DS tools for grasslands. A survey of the present state of …

Decision Support For Grassland Systems In Developing Countries, P. K. Thornton

IGC Proceedings (1977-2023)

Key points

1. Information flows in complex systems are often themselves highly complex, and decision support approaches based on linear input-output processes may have only limited impact.

2. How decisions are made, and how they can be appropriately supported, is often incompletely understood, in part because of inadequate understanding of the objectives and attitudes of all the decision makers involved.

3. Much of the developing world faces daunting problems in the coming 30 years, and appropriate information could play a critical role in dealing with these.

4. System complexity, household variability, and institutional intricacies have to be embraced rather than …

Best Practices For Highway Project Scoping, Jeff Jasper, Samantha Wright, Jon Wilcoxson, Robin Baskette, Christopher Van Dyke

Kentucky Transportation Center Research Report

One of the Kentucky Transportation Cabinet’s (KYTC) foremost priorities in fulfilling its mission is to deliver successful projects — quality solutions that meet the defined scope and are delivered on time and within the budget specified in the Highway Plan. When a project scope is not clearly defined or uncertain, revisions may take place after the project is already underway, leading to delays or overpromising what can be delivered. Ideally, a reliable, decisive project scope is defined in the early phases of the highway project development process. The scope should include a project definition that clearly communicates the project scope’s …

Social Media And Contentious Action: The Use And Users Of Qq Groups In China, Zixue Tai

Journalism and Media Faculty Publications

This article presents an analysis of a netnographic study of QQ groups engaged in contentious activities in China. Informed primarily by semi‐structured in‐depth interviews of 34 participants and field observations through years of grounded research, the findings shed light on the communicative dynamics and mobilization strategies of QQ groups in nurturing contentious action and motivating mass participation in social protest. In‐group communication stays highly focused on the respective mission of the groups, and it cultivates a sense of shared awareness conducive to collective action. There is also a noticeable contagion effect that transfers the spirit of contestation in terms of …

The Geopolitics Of Infrastructuralized Platforms: The Case Of Alibaba, Hong Shen, Yujia He

Patterson School of Diplomacy and International Commerce Faculty Publications

Contemporary digital platforms have become increasingly infrastructuralized, and started to raise geopolitical tensions with their global expansion. Amidst the heightened geopolitical competition between the US and China, the growing power of Chinese infrastructuralized platforms has made them the center of recent geopolitical dynamics. Drawing from an exploratory case study, this paper discusses Alibaba, one of the most prominent Chinese Internet giants, as an infrastructuralized platform, and highlights its geopolitical struggles. Often perceived as an e-commerce company, Alibaba has become ‘infrastructuralized’: its now-massive digital empire has moved beyond e-commerce, expanding into almost every aspect of China’s and global digital economy such …

Barriers And Facilitators To Stool-Based Screening For Colorectal Cancer Among Black Louisville Residents, Aaron J. Kruse-Diehr, Derek Cegelka, Elizabeth Holtsclaw, Jerod L. Stapleton, Camille Burnett, Rose Wood, Carlee Combs, Lovoria B. Williams

UK CARES Faculty Publications

Knowledge of colorectal cancer (CRC) screening options remains suboptimal in Black populations, contributing to screening disparities. Guided by community-based participatory research (CBPR) principles, we partnered with five Black churches in Louisville, a region of Kentucky with high Black-white CRC screening disparities, to explore screening barriers and facilitators for CRC education and outreach. Project champions (n = 5) served as primary points of contact, developed project support within their churches, and were trained to recruit church and community members (n = 39) to participate in five semi-structured focus groups. Interview questions probed actual and perceived barriers to CRC screening, focusing on …

Digital Twin For Hvac Load And Energy Storage Based On A Hybrid Ml Model With Cta-2045 Controls Capability, Rosemary E. Alden, Evan S. Jones, Huangjie Gong, Abdullah Al Hadi, Dan Ionel

Power and Energy Institute of Kentucky Faculty Publications

Building modeling, specifically heating, ventilation, and air conditioning (HVAC) load and equivalent energy storage calculations, represent a key focus for decarbonization of buildings and smart grid controls. Widely used white box models, due to their complexity, are too computationally intensive to be employed in high resolution distributed energy resources (DER) platforms without simulation time delays. In this paper, an ultra-fast one-minute resolution Hybrid Machine Learning Model (HMLM) is proposed as part of a novel procedure to replicate white box models as an alternative to widespread experimental big data collection. Synthetic output data from experimentally calibrated EnergyPlus models for three existing …

Reactivity Of Aminophenols In Forming Nitrogen-Containing Brown Carbon From Iron-Catalyzed Reactions, Hind A. Al-Abadleh, Fatemeh Motaghedi, Wisam Mohammed, Md Sohel Rana, Kotiba A. Malek, Dewansh Rastogi, Akua A. Asa-Awuku, Marcelo I. Guzman

Chemistry Faculty Publications

Nitrogen-containing organic carbon (NOC) in atmospheric particles is an important class of brown carbon (BrC). Redox active NOC like aminophenols received little attention in their ability to form BrC. Here we show that iron can catalyze dark oxidative oligomerization of o- and p-aminophenols under simulated aerosol and cloud conditions (pH 1–7, and ionic strength 0.01–1 M). Homogeneous aqueous phase reactions were conducted using soluble Fe(III), where particle growth/agglomeration were monitored using dynamic light scattering. Mass yield experiments of insoluble soot-like dark brown to black particles were as high as 40%. Hygroscopicity growth factors (κ) of these …

Investigation Of Illegal Weigh Station Bypassing, Mallory Brown, Andrew Martin, David Leddy, Jennifer Walton

Kentucky Transportation Center Research Report

This study recommends best practices to curb illegal weigh station bypassing by commercial motor vehicles (CMVs). Analysis of historical data collected by Kentucky State Police – Commercial Vehicle Enforcement (KSP-CVE) for 2017-2021 revealed that CMV drivers were charged with illegally bypassing weigh stations 2,616 times. Drivers were charged with an average of two other violations when cited for illegal bypassing — most often violations related to credentialing, vehicle safety, or driver safety. Site visits to three permanent weigh stations in Kentucky revealed that CMVs regularly bypass weigh stations illegally, including those authorized to use preclearance systems (Drivewyze and PrePass).

The Gospel Of Freedom, Alicestyne Turley

Civil Rights

Wilbur H. Siebert published his landmark study of the Underground Railroad in 1898, revealing a secret system of assisted slave escapes. A product of his time, Siebert based his research on the accounts of northern white male abolitionists. While useful in understanding the northern boundaries of the slaves' journey, Siebert's account leaves out the complicated narrative of assistance below the Mason-Dixon Line. In The Gospel of Freedom: Black Evangelicals and the Underground Railroad, author Alicestyne Turley positions Kentucky as a crucial "pass through" territory for escaping slaves and addresses the important contributions of white and black antislavery southerners who united …

Oral Health Science Faculty Publications

(1) Background: Painful nervus intermedius neuropathy involves continuous or near-continuous pain affecting the distribution of the intermedius nerve(s). The diagnosis of this entity is challenging, particularly when the clinical and demographic features do not resemble the typical presentation of this condition. To the best of our knowledge, only three case reports have described the occurrence of nervus intermedius neuropathy in young patients. (2) Case Description: A 13-year-old female referred to the orofacial pain clinic with a complaint of pain located deep in the right ear and mastoid area. The pain was described as constant, throbbing and dull, with an intensity …

Products Of Ideals And Golod Rings, Keller Vandebogert

Mathematics Faculty Publications

In this paper, we study conditions guaranteeing that a product of ideals defines a Golod ring. We show that for a 3-dimensional regular local ring (or 3-variable polynomial ring) (R, m), the ideal Im always defines a Golod ring for any proper ideal I ⊂ R. We also show that non-Golod products of ideals are ubiquitous; more precisely, we prove that for any proper ideal with grade ≥ 4, there exists an ideal J ⊆ I such that IJ is not Golod. We conclude by showing that if I is any proper ideal in a 3-dimensional regular local ring and …

Krs And Kar Review Of Models As A Legal Contract Document, Bryan Gibson, Pam Clay-Young, Rachel Catchings, Chris Van Dyke

Kentucky Transportation Center Research Report

State departments of transportation (DOTs) are expanding the use of electronic engineering data (EED) throughout highway projects — from design and construction through asset management. Included under the umbrella of EED are technologies such as building information modelling (BIM), digital terrain models (DTMs), and 3D models and plan sets. The Kentucky Transportation Cabinet’s (KYTC) Digital Project Delivery (DPD) Initiative is spearheading the transition to EED in the state. While digital delivery promises to streamline project development and management it does not come without hurdles. This report discusses methods for agency wide implementation of EED and highlights best practices for managing, …

Exploration Of Vaccination Attitudes Among Parents And Caregivers In A Rural Appalachian Health Clinic, Radwa Omar, Karen Hande, Natasha Mcclure

Journal of Appalachian Health

At a rural Appalachian health clinic in Kentucky, 20% of patients under 18 years were not up to date with the CDC-recommended immunization schedule. Reasons parents or caregivers chose to delay or refuse their child’s immunizations were explored using the Caregiver Vaccination Attitude Scale. High levels of trust in the healthcare provider and self-reported vaccine knowledge highlight opportunities for rural healthcare providers to apply evidence-based communication strategies to address vaccine hesitancy and promote the safety and health of the entire community.

Sanders-Brown Center on Aging Faculty Publications

Elucidating the impact of the gut microbiome on Alzheimer’s Disease (AD) is an area of intense interest. Short chain fatty acids (SCFAs) are major microbiota metabolites that have been implicated as a mediator of gut microbiome effects in the brain. Here, we tested the effects of SCFA-treated water vs. saline-treated water on APPswe/PSEN1dE9 mice maintained under standard laboratory conditions. Mice were treated with SCFAs from five months of age until ten months of age, when they were evaluated for microbiome profile, impaired spatial memory as evaluated with the radial arm water maze, astrocyte activation as measured by Gfap expression and …

Chinese-Backed Fintech Lending Boom: How Did Indonesia Respond?, Angela Tritto, Yujia He, Victoria Amanda Junaedi

Diplomacy and International Commerce Reports

Peer-to-peer (P2P) online lending has the potential to boost innovation and financial inclusion in emerging markets, yet it can also incur investment and borrower-related risks, such as privacy breaches.

Driven by regulation control in China, Chinese investments flocked to Indonesia, causing a rapid expansion of online lending platforms.

Similar to what happened in China prior to the regulatory crackdown, the P2P lending boom in Indonesia saw a rise in unethical and illegal business practices. The government responded by creating new regulations and institutions to mitigate risks without stifling the potential for financial inclusion.

A proactive approach towards monitoring and regulating …

Moral Distress During Covid-19: The Importance Of Perceived Organizational Support For Hospital Nurses, Abigail Latimer, Melanie D. Otis, Gia Mudd-Martin, Debra K. Moser

UK CARES Faculty Publications

Moral distress, or the inability to act congruent with moral beliefs, has been of concern for healthcare professionals especially since the COVID-19 pandemic. Hospital nurses are particularly affected in their roles with mounting administrative pressures and demands. We examined whether general and COVID- specific support in employing healthcare organizations predicted moral distress in a sample of inpatient hospital nurses. A total of 248 nurses completed the Measure of Moral Distress for Healthcare Professionals, Survey of Perceived Organizational Support, COVID Organizational Support survey, and the Hospital Ethical Climate Scale. We found that general and COVID-related organizational support were predictors of moral …
