Integrated pest management uses a variety of tools coupled with historical, current, and projected information for economical pest protection of crops and other resources while accounting for risk to humans and the environment. Following the 1972 US Federal IPM Policy, funding for integrated pest management programming has continued for 50+ years. However, multifaceted changes during this time have significantly affected state-level integrated pest management infrastructure, prompting a comprehensive survey to assess conditions, limitations, and growth potential of US integrated pest management programs. A survey was sent to 50 US states and 3 territories with integrated pest management programs in November …

Reconciling Jekyll And Hyde: The Future Of Masculinity Research Within The Domestic Violent Extremism Context, Sam T. Hunter, Brett H. Neely, Carter Welch, Amanda N. Moeller

Department of Management: Faculty Publications

Violence among young men in the United States has escalated in recent years, leading to two contrasting perspectives of young men—either as (a) agentic aggressors or (b) by-products of societal shifts that have caused disadvantage. The first perspective characterizes men as entitled and reactionary, prone to aggression when their societal expectations are unmet. This view aligns with the frustration-aggression hypothesis in which unmet desires lead to hostile behaviors, particularly among individuals who perceive a loss of status and significance. Conversely, the second perspective views men as victims of rapid societal changes, such as job displacement, educational disparities, and shifting gender …

Greenhouse Management For The Smaller Structure--Educational And Hobby, Stacy A. Adams

Department of Agronomy and Horticulture: Faculty Publications

Greenhouses used for teaching or by hobbyist are smaller than those used for commercial production or found in the retail environment. Structural materials, covering, mechanical equipment, and control systems often are packaged as a kit made available through greenhouse suppliers.

Inactivation Of Zika Virus With Hydroxypropyl-Beta-Cyclodextrin, Cory R. Hewitt, Nicholas J. Wixon, Arthur Gallegos, You Zhou, Victor C. Huber, M. Scott. Killian

Nebraska Center for Biotechnology: Faculty and Staff Publications

Background/Objectives: Zika virus (ZIKV) infection is associated with life-threatening diseases in humans. To date, there are no available FDA-approved therapies or vaccines for the specific treatment or prevention of ZIKV infection. Variation in the ZIKV envelope protein (Env), along with its complex quaternary structure, presents challenges to synthetic approaches for developing an effective vaccine and broadly neutralizing antibodies (bnAbs). We hypothesized that beta-cyclodextrin (BCD) could be used to uniquely inactivate infectious ZIKV without disruption of Env.

Methods: ZIKV was propagated in Vero cells and admixed with BCD. The BCD-treated ZIKV was evaluated for infectivity using immunofluorescence and quantitative …

Microscopic Analysis Of Temperature Effects On Surface Colonization And Biofilm Morphology Of Salmonella Enterica, Zachariah Vice, You Zhou, Sapna Chitlapilly Dass, Rong Wang

Nebraska Center for Biotechnology: Faculty and Staff Publications

Salmonella enterica represents a diverse group of pathogens commonly associated with food contamination including red meat. Even though pre- and post-harvest cleaning and sanitization procedures are widely implemented at meat processing plants to mitigate the hazard, S. enterica cells may escape the process by colonizing, on contact, surfaces in the form of a biofilm that functions as an aggregated microbial community to facilitate mutual protection, antimicrobial resistance, proliferation and dissemination. Biofilm development is a complex process that can be affected by a variety of factors including environmental temperature. We developed methods using scanning electron microscopy and confocal microscopy with a …

Characterization Of Multispecies Microbial Communities At Beef And Pork Processing Plants And Their Impact On Pathogen Stress Tolerance, Rong Wang, Sapna Chitlapilly Dass, Vignesh Palanisamy, You Zhou, Tatum Katz, Joseph M. Bosilevac

Nebraska Center for Biotechnology: Faculty and Staff Publications

Escherichia coli O157:H7 and Salmonella enterica are major foodborne pathogens. Biofilm formation may potentially contribute to product contamination by these pathogens at meat processing facilities. Further, pathogen stress tolerance may vary significantly due to the interactions with the multispecies microbial community at meat plants, which may be affected by processing activity, animal species, and the local selective pressure caused by sanitization practices.

We characterized natural microorganisms collected from floor drains at various areas at three beef plants and two pork plants and analyzed their impact on pathogen sanitizer tolerance.

The pathogen strains were able to integrate efficiently into the multispecies …

Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho

Karl Reinhard Publications

Archaeoparasitology has been conducted in the Southwest for 57 years. In the first decade of the period, two pictures of parasitism emerged. Analysis of compressed organic sediments from a latrine at Elden Pueblo presented a spectrum of geohelminths not different from medieval Europe. These findings contrast pronouncedly with an analysis of coprolites from all other studies that show consistent pinworm parasitism at other sites in the Southwest. We summarize the paleoepidemiological bases for these contrasting phenomena.

Helminth Parasites Of Galápagos Mammals: A New Cestode Of The Genus Raillietina From The Endemic Rice Rat Nesoryzomys Swarthi And A Summary Of Parasites From Both Endemic And Invasive Rodents, Scott Lyell Gardner, Emma K. Chesley, Michael C. Friedle, Altangerel Tsogtsaikhan Dursahinhan

Scott L. Gardner Publications

In this first report of endoparasites from endemic land-mammals of the Galápagos Islands, we describe a new species of cestode of the genus Raillietina (Cyclophyllidea: Davaineidae) from a species of Nesoryzomys and summarize the extent of helminth parasitism in both oryzomyine endemics and introduced species of Rattus. Up to the current time, no helminth parasites have been reported from rodents of the Galápagos, and little work has yet been done describing and synthesizing Galápagos parasite diversity. In historical times, several species of autochthonous rodents have occupied the islands including: Nesoryzomys narboroughi Heller 1904, N. fernandinae Hutterer and Hirsch …

Identification Of Benzothiophene-Derived Inhibitors Of Flaviviruses By Targeting Rna-Dependent Rna Polymerase, Leah Liu Wang, Shazeed-Ul Karim, Aidan Hand, Ryan Brunkhorst, Mackenna Petersen, Sarah Altam, Yi Liu, Luwen Zhang, Fengwei Bai, Shi-Hua Xiang

School of Biological Sciences: Faculty Publications

Flaviviruses such as Dengue, West Nile, and Zika viruses are mosquito-borne RNA viruses that can cause serious diseases in humans. To develop effective drugs for treating these viruses’ infections, we create a new approach for developing common or shared drugs that may work for several different viral species of flaviviruses. It is based on the conserved RNA-dependent RNA polymerase (RdRp), which is the key enzyme for viral replication. We built up a common structure of RdRps (POLcon) from their consensus sequence. A conserved Triple-D structural motif was identified at the active site of POLcon that has been used for virtual …

Wondrous Uncertainty: Transforming Student Educational Experiences Using Restorative Practices, Zachary C. Schafer

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

One of the primary purposes of education is to help students make sense of their lived experiences. In the process of becoming, students navigate multiple relationships (school, peers, adults, and with self). These relationships often cause conditions of uncertainty which can be managed and transformed using restorative practices in tandem with the academic disciplines taught in school. Over the last decade this has been my inquiry puzzle, “As educators, how can we embrace uncertainty with students as a way of helping to empower them through their dignity, with the academic disciplines as a lens through which relational learning occurs in …

Group And State-Specific Estimation In Animal Movement Models Using A Bayesian Approach, Anita Bhandari Sharma

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This research study investigates statistical approaches for modeling the movement patterns of white-tailed deer in Louisiana using GPS tracking data. We start by classifying the latent behavioral states using a hidden Markov model (HMM) and then integrate those inferred states into a state-dependent step selection framework to evaluate the land cover preferences. Standard HMMs, however, assume the same movement patterns for all animals, overlooking the differences due to characteristics such as sex, age, breeding season, etc.

To address this limitation, we extend the modeling framework to incorporate the group-level structure defined by similar characteristics or conditions to assess whether such …

Coaching Strategies For Instructional Improvement: Social Emotional Learning In The Preschool Classrooms, Maria Eleanor Yniguez Del Rosario

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Grounded in the collaborative principles of PAR, the study positioned instructional coaches as co-researchers.

The research was conducted within the LPS Department of Early Childhood Education, involving four preschool instructional coaches. Data were generated through semi-structured interviews, coaches’ classroom observations, informal teacher-coach conversations, researcher’s observations of coaching sessions, and a group reflection session. Using an iterative analytical approach (Tracy, 2020), the study examined how coaching strategies evolve and the conditions that …

Adapting Gingles & Retaining Voter Power: Applying The Vra To State Judicial Retention Elections, Jake Mazeitis

Nebraska Law Review

State supreme courts play a crucial yet overlooked role in our nation’s judiciary. They are also predominantly White. In states with judicial elections, this racial homogeneity suggests that voters of color may not have an equal opportunity to “elect representatives of their choice” as required by the Voting Rights Act (VRA). While federal courts frequently apply the VRA to judicial elections resembling legislative and executive contests, those same tribunals have failed to protect voters of color in non-competitive judicial retention elections. This failure is due in part to Thornburg v. Gingles, which established three threshold requirements for plaintiffs in …

Diversity Statements, Academic Freedom, And The First Amendment, Keith E. Whittington

Nebraska Law Review

Diversity statements have become a common component of applications for faculty positions and student admission at universities across the country. They have also become politically controversial, with several states banning the use of such requirements at public universities. The use of diversity statements also raises difficult constitutional questions under the First Amendment at public universities and academic freedom questions at both public and private universities. Although there are versions of such statements that might pass constitutional muster, as commonly designed and implemented, the use of diversity statements likely violates both First Amendment and academic freedom principles. Indeed, diversity statement requirements …
