Tar spot on corn, caused by the fungus (Phyllachora maydis Maubl. [Phyllachorales: Phyllachoraceae]), is an emerging disease in the United States. In 2018 and 2019, significant but localized epidemics of tar spot occurred across the major corn producing region of the Midwest. After being first detected in 2015, tar spot was detected in 135 and 139 counties where the disease was not previously detected in 2018 and 2019, respectively, and is now established across 310 counties across the United Sates. Foliage with signs (stromata) of P. maydis and symptoms of tar spot were collected from 128 fields in 2018 and …

Biology And Management Of The Rice Stink Bug (Hemiptera: Pentatomidae) In Rice, Oryza Sativa (Poales: Poaceae), Santhi Bhavanam, Blake Wilson, Bryce Blackman, Michael Stout

Faculty Publications

The rice stink bug, Oebalus pugnax (Fabricius), is the most important late-season insect pest of rice in the southern United States. Nymphs and adults feed on rice grains, resulting in losses in yield and grain quality. Aspects of the biology, ecology, life history, and chemical ecology have been investigated in southern rice producing states but several outstanding questions remain. Standard economic threshold levels (ETLs) based on sweep net sampling for rice stink bug have been established depending on grain development stage and geographic location. However, recent studies on the relationship between rice stink bug densities, feeding damage, and its economic …

Climate Mismatch Between Introduced Biological Control Agents And Their Invasive Host Plants: Improving Biological Control Of Tropical Weeds In Temperate Regions, Nathan E. Harms, Ian A. Knight, Paul D. Pratt, Angelica M. Reddy, Abhishek Mukherjee, Ping Gong, Julie Coetzee, S. Raghu, Rodrigo Diaz

Faculty Publications

Many weed biological control programs suffer from large-scale spatial variation in success due to restricted distributions or abundances of agents in temperate climates. For some of the world’s worst aquatic weeds, agents are established but overwintering conditions limit their survival in higher latitudes or elevations. The resulting need is for new or improved site-or region-specific biological control tools. Here, we review this challenge with a focus on low-temperature limitations of agents and propose a roadmap for improving success. Investigations across spatial scales, from global (e.g., foreign exploration), to local (selective breeding), to individual organisms (molecular modification), are discussed. A combination …

Sugar Recovery Rates In Louisiana, Florida, And Australia (1901–2018): Sugarcane Varietal Development And Cultural Practices, P. Lynn Kennedy, Andrew Schmitz, Fangyi Zhang

Faculty Publications

Australia, Florida, and Louisiana are dominant sugar producers. We use piecewise regression to compare the growth in sugar recovery rates. To discuss sugarcane (Saccharum officinarum L.) varietal development and cultural practices, we consider two scenarios: the entire period 1901 to 2018 and two subperiods using country-specific breakpoints. The overall annual increase in the sugar recovery rate for all three regions ranged between 0.0180% for Australia and 0.0525% for Florida. In the first subperiod, Florida (0.2380%, 1928–1941) and Australia (0.1233%, 1901–1927) have the greatest annual gains, but in the second subperiod, Louisiana experiences the greatest annual gains (0.0813%, 1969–2018), followed by …

Kentucky Soybean Farmers' Supportiveness Of Two Integrated Pest And Pollinator Management Tactics, Hannah J. Penn, Jerrod Penn, Michael Cunningham-Minnick, Wuyang Hu

Faculty Publications

Beneficial insect conservation in agriculture is often studied in the context of integrated pest management (IPM). For instance, vegetative field edges provide habitat and changing the timing of insecticidal sprays decreases risk for pollinators and natural enemies of insect pests. However, the attitudes and confidence of U.S. growers towards IPM implementation in traditional row crops remain understudied. We developed an online survey using a convenience sample and surveyed Kentucky soybean growers to understand their current pest and general management practices, beliefs about sources of insect pests/weeds, and attitudes towards pollinators. We also asked about their willingness to implement two management …

(Sl(N),Q) -Opers, The Q-Langlands Correspondence, And Quantum/Classical Duality, Peter Koroteev, Daniel S. Sage, Anton M. Zeitlin

Faculty Publications

A special case of the geometric Langlands correspondence is given by the relationship between solutions of the Bethe ansatz equations for the Gaudin model and opers-connections on the projective line with extra structure. In this paper, we describe a deformation of this correspondence for SL(N). We introduce a difference equation version of opers called q-opers and prove a q-Langlands correspondence between nondegenerate solutions of the Bethe ansatz equations for the XXZ model and nondegenerate twisted q-opers with regular singularities on the projective line. We show that the quantum/classical duality between the XXZ spin chain and the trigonometric Ruijsenaars–Schneider model may …

Yank And Rebel Rangers: Special Operatives In The American Civil War, Meg Groeling

Civil War Book Review

Black approaches his subjects “clearly and without prejudice” in chapters dedicated to specific operatives in both armies. Black’s examination of Union Army ranger C. Lorain Ruggles and President Lincoln’s antebellum service in Captain Elijah Isle’s company of Independent Rangers in the Black Hawk War are of special interest. In the end, Groeling recommends Black’s Yank and Rebel Rangers “to anyone interested in partisan warfare in general and Civil War partisans specifically.”

Phenomenological Implications Of Modified Loop Cosmologies: An Overview, B F. Li, P Singh, A Z. Wang

Faculty Publications

In this paper, we first provide a brief review of the effective dynamics of two recently well-studied models of modified loop quantum cosmologies (mLQCs), which arise from different regularizations of the Hamiltonian constraint and show the robustness of a generic resolution of the big bang singularity, replaced by a quantum bounce due to non-perturbative Planck scale effects. As in loop quantum cosmology (LQC), in these modified models the slow-roll inflation happens generically. We consider the cosmological perturbations following the dressed and hybrid approaches and clarify some subtle issues regarding the ambiguity of the extension of the effective potential of the …

Matchless Organization: The Confederate Army Medical Department, Dale C. Smith

Civil War Book Review

Hasegawa shows that phenomena endemic to the Confederacy’s government and culture—namely material want and overwrought independence—hampered attempts to systematize and rationalize the Confederate Army’s medical department. Reviewer Dale C. Smith believes “anyone with a serious interest in the War of the Rebellion medicine should read it.”

Gamma-ray bursts (GRBs) are among the brightest and most energetic events in the Universe. The duration and hardness distribution of GRBs has two clusters(1), now understood to reflect (at least) two different progenitors(2). Short-hard GRBs (SGRBs; T-90 < 2 s) arise from compact binary mergers, and long-soft GRBs (LGRBs; T-90 > 2 s) have been attributed to the collapse of peculiar massive stars (collapsars)(3). The discovery of SN 1998bw/GRB 980425 (ref. (4)) marked the first association of an LGRB with a collapsar, and AT 2017gfo (ref. (5))/GRB 170817A/GW170817 (ref. (6)) marked the first association of an SGRB with a binary neutron star merger, which also produced a gravitational wave. Here, we present the discovery …

Caregiver Treatment Consumption In An Experimental Treatment Marketplace, Delaney J. Darragh

Faculty Publications

Behavioral economics is an approach to understanding consumer behavior by integrating behavioral science with economic principles. Behavioral economics incorporates traditional economic principles with operant learning approaches. There is limited research examining how individuals consume psychological and behavioral treatments. This is especially the case for treatments designed for children. The current study used data from a previously collected sample to explore gender differences in an experimental treatment marketplace (ETM). Experimental treatment marketplaces are generally used to evaluate choices between goods and services (e.g., types of behavior interventions). An ETM was developed to evaluate treatment consumption when levels of evidence differed between …

Distinguishing Relational Turbulence, Marital Satisfaction, And Parenting Stress As Predictors Of Ineffective Arguing Among Parents Of Children With Autism, Kellie St Cyr Brisini, Denise Haunani Solomon

Faculty Publications

Relational turbulence theory suggests that relational turbulence causes pervasive patterns of dysfunctional communication in romantic relationships, such as an inability to resolve conflicts. Other research traditions link marital conflict to marital satisfaction and also exposure to stress. This study assesses the discriminant validity of relational turbulence by examining its association with reports of ineffective arguing, above and beyond the associations with marital satisfaction and parenting stress. The study tests the theoretical claims within the high stress context of parents raising children with autism spectrum disorder (ASD). Married, parents of children with ASD (N = 298) completed measures of parenting stress …

Going Feminine: Identifying How And When Female Candidates Emphasize Feminine And Masculine Traits On The Campaign Trail, Nichole M. Bauer, Martina Santia

Faculty Publications

Female candidates face a messaging challenge. There is a strong association between masculinity and political leadership. Stressing masculinity can result in a likability backlash for female candidates often seen as lacking feminine qualities, such as warmth. Preventing a likability backlash by highlighting feminine qualities can also harm female candidates. Current scholarship offers conflicting conclusions about how female candidates balance these gendered challenges. We fill this empirical and theoretical gap with a trait-balancing theory clarifying how and when female candidates use feminine and masculine traits to manage competing expectations. We use original data merging information on candidate advertising strategies across three …

Siah2 Is Expressed In Adipocyte Precursor Cells And Interacts With Ebf1 And Zfp521 To Promote Adipogenesis, Thanh N. Dang, Jessica L. Taylor, Gail Kilroy, Yongmei Yu, David H. Burk, Z. Elizabeth Floyd

Division of Basic Science Faculty Publications

Objective: Expression of zinc finger protein 423 (ZFP423), a key proadipogenic transcription factor in adipocyte precursor cells, is regulated by interaction of the proadipogenic early B-cell factor 1 (EBF1) and antiadipogenic ZFP521. The ubiquitin ligase seven-in-absentia homolog 2 (SIAH2) targets ZFP521 for degradation. This study asked whether SIAH2 is expressed in adipocyte precursor cells and whether SIAH2 interacts with ZFP521 and EBF1 to regulate ZFP521 protein levels during adipogenesis. Methods: SIAH2 expression in precursor cells was assessed in primary cells and tissues from wild-type and SIAH2 null mice fed a control or high-fat diet. Primary cells, 3T3-L1 preadipocytes, and HEK293T …

Effect Of An Office-Based Intervention On Visceral Adipose Tissue: The Workactive-P Randomized Controlled Trial, James L. Dorling, Christoph Höchsmann, Catrine Tudor-Locke, Robbie Beyl, Corby K. Martin

Clinical Research Faculty Publications

Office-based activity reduces sedentariness, yet no randomized controlled trials (RCTs) have assessed how such activity influences visceral adipose tissue (VAT). This study examined the effect of an office-based, multicomponent activity intervention on VAT. The WorkACTIVE-P RCT enrolled sedentary office workers (body mass index: 31.4 (standard deviation (SD) 4.4) kg/m2 ) to an intervention (n = 20) or control (n = 20) group. For 3 months, the intervention group received an office-based pedal desk, further to an intervention promoting its use and increased walking. The control group maintained habitual activity. At baseline and follow-up, VAT, cardiometabolic disease risk markers, physical activity, …

Agronomic And Environmental Performance Of Biochar Amendment In Alluvial Soils Under Subtropical Sugarcane Production, Negar Tafti, Jim Wang, Lewis Gaston, Jong Hwan Park, Meng Wang, Scott Pensky

Faculty Publications

This study investigated the amendment of sugarcane bagasse biochar (SCBB) on soil fertility, crop yield, and nutrient loss in two different-textured soils under sugarcane (Saccharum spp.) production. Eleven megagrams per hectare of freshly incorporated biochar increased yield of plant cane by 22% in light-texture soil (LS) and 12% in heavy-textured soil (HS). Although the overall yield of the ratoon crop was lower, the biochar treatment produced 20 and 14% higher yields than the control at the LS and HS sites, respectively. Biochar increased soil carbon (Csoil) across LS and HS sites by 15% and decreased the soil C/N ratio by …

Regular physical activity improves physical and mental health across all ages, and provides many social, environmental, and economic co-benefits. Physical activity includes all forms of active recreation, sports participation, cycling and walking for transportation, as well as activity undertaken at home or for work. Despite well-established benefits, one quarter of adults and three quarters of adolescents are not sufficiently active. The policy and practice of promoting physical activity integrates multidisciplinary knowledge from across clinical and social medicine, exercise science, health psychology, public health, transport, and environmental studies, to improve global health. With increasing recognition of its role in promoting better …

Sympathetic Innervation Of White Adipose Tissue: To Beige Or Not To Beige?, Heike Münzberg, Elizabeth Floyd, Ji Suk Chang

Division of Basic Science Faculty Publications

Obesity research progresses in understanding neuronal circuits and adipocyte biology to regulate metabolism. However, the interface of neuro-adipocyte interaction is less studied. We summarize the current knowledge of adipose tissue innervation and interaction with adipocytes and emphasize adipocyte transitions from white to brown adipocytes and vice versa. We further highlight emerging concepts for the differential neuronal regulation of brown/beige versus white adipocyte and the interdependence of both for metabolic regulation.

Digital Tools To Support Family-Based Weight Management For Children: Mixed Methods Pilot And Feasibility Study, Amanda E. Staiano, Jenelle R. Shanley, Holly Kihm, Keely R. Hawkins, Shannon Self-Brown, Christoph Höchsmann, Melissa C. Osborne, Monique M. Leblanc, John W. Apolzan, Corby K. Martin

Clinical Research Faculty Publications

Background: Family-based behavioral therapy is an efficacious approach to deliver weight management counseling to children and their parents. However, most families do not have access to in-person, evidence-based treatment. We previously developed and tested DRIVE (Developing Relationships that Include Values of Eating and Exercise), a home-based parent training program to maintain body weight among children at risk for obesity, with the intent to eventually disseminate it nationally alongside SafeCare, a parent support program that focuses on parent-child interactions. Currently the DRIVE program has only been tested independently of SafeCare. This study created the “mHealth DRIVE” program by further adapting DRIVE …
