Episode 332 - From Herd Counts to Cow Scratches: What’s Changing in Midwest Dairies - UMN Extension's The Moos Room
No full textRuntime 00:17:45On a warm-for-February day in Minnesota, Brad dives into two topics shaping today’s dairy landscape: changing dairy herd demographics in the Upper Midwest and new research on dairy cow preferences for grooming brushes. The episode opens with a look at dairy farm numbers in Minnesota, where the state has lost nearly 37% of its dairy farms since 2019—dropping from 2,567 to just 1,622 operations. Brad breaks down herd size distribution, showing Minnesota remains dominated by small herds (especially 50–100 cows), even as the number of very large herds continues to grow. He also highlights where dairy farms are concentrated geographically, with Stearns County leading the state, and notes that seven Minnesota counties now have no dairy farms at all. Brad then compares Minnesota to Wisconsin, which still has over 5,100 licensed dairy farms. Wisconsin’s dairy industry includes a notable number of goat dairies (nearly 400) and a small but interesting presence of sheep dairies. He walks through the top dairy counties in Wisconsin, illustrating how dairy production clusters in central, southwestern, and Green Bay–adjacent regions. In the second half of the episode, Brad discusses a new Purdue University study examining dairy cow preferences for grooming brushes. Researchers compared three brush types—swinging and rotating, swinging only, and stationary—and found that more than 75% of cows preferred the swinging, rotating brush. Cows spent several minutes grooming their heads, backs, and rumps, with rotating brushes offering the most engagement and relaxation. While stationary brushes were used mainly for head scratching, the study suggests that offering a variety of brush types may give cows valuable choice and enrichment. Brad wraps up by reflecting on what these trends mean for dairy farm viability, animal welfare, and management decisions—leaving listeners with practical insights and plenty to think about.Heins, Brad.

A Unified Theory of Nursing Professional Development: Integrating Clinical Reasoning, Consciousness Development, and Foresight Leadership
No full textThis article proposes a Unified Theory of Nursing Professional Development that identifies three developmentally intertwined capacities essential for comprehensive professional expertise. The first is clinical reasoning capacity—how nurses think about patient care, coordinate care across systems, and make judgments under conditions of complexity and uncertainty. The second is consciousness development capacity—how nurses make meaning of themselves, their work, and their impact, evolving the internal operating systems through which they interpret and navigate professional life. The third is foresight leadership capacity—how nurses anticipate disruptive changes, envision preferred futures, and lead innovation that shapes rather than merely responds to transformation. The central argument is that these three capacities are not separate competency domains to be developed independently but expressions of a single underlying metacognitive architecture. The cognitive processes that enable a nurse to juxtapose a patient’s present state against a desired outcome, identify keystone issues, and test interventions are structurally identical to those required to examine one’s own meaning-making structures and evolve toward greater developmental complexity. Both, in turn, enable the anticipatory capacity to scan environmental signals, envision organizational futures, and lead adaptive change. Separating them—as current frameworks do—produces consequences the profession can no longer afford.Nursing faces an unprecedented dual imperative: cultivating clinical reasoning capabilities for sound practice and consciousness development for meaning making, combined with foresight leadership capacities for anticipatory action. Yet the profession lacks an integrative theoretical framework connecting these demands. This article proposes a Unified Theory of Nursing Professional Development that synthesizes three developmentally intertwined capacities: clinical reasoning capacity (how nurses think about patient care), consciousness development capacity (how nurses make meaning of themselves, their work, and their impact), and foresight leadership capacity (how nurses anticipate and shape the future). Drawing on the Outcome-Present State-Test (OPT) Model of Clinical Reasoning, constructive-developmental psychology, polarity management, caring science, partnership theory, futures studies, and complexity science, the theory articulates how these capacities share a common metacognitive architecture and operate across five nested scales: individual, team, organizational, professional, and societal. The theory’s central claim—that the cognitive process of juxtaposing present states against desired outcomes is structurally isomorphic across clinical reasoning, consciousness development, and foresight leadership—is demonstrated through component mapping and illustrated through a case exemplar. Implications for nursing education, leadership development, and human-AI collaboration are discussed, including a concrete integrated curriculum design. The ultimate purpose of this unified development is not individual advancement but collective capacity for creating caring healthcare systems and a more just, sustainable world.Pesut, Daniel. (2026).

Determining Intrafamilial Epstein-Barr Virus Transmission through LMP-1 Strain Variation Sequence Genotyping
No full textFaculty Advisor: Dr. Hank BalfourThe Epstein-Barr virus (EBV) infects about 90% of the global population1. EBV can cause infectious mononucleosis (mono) which is known as the “kissing disease” because exchange of oral fluids during kissing is the most common mode of transmission among teenagers and young adults. However, the method of transmission of the EBV is unknown in preadolescent children due to the lack of testing and awareness of the disease3. It is likely that caretakers, while contagious with the virus, pass it down to their children, who can then spread it to other children. Comparing the parent’s strain of the EBV LMP-1 gene against that of their children could provide insights into how the highly contagious infection spreads to eventually infect a large population. A nested PCR was used to identify the EBV gene strains amongst children and their parents. The assay produced no bands.This research was supported by the Undergraduate Research Opportunities Program (UROP).Cocasse, Anjali. (2026).

Behavioral Investigation of Temporary and Permanent Pedestrian Infrastructure
No full textAgencies may treat pedestrian crossing sites initially with temporary treatments (i.e., removable flexible delineators or bollards) to test efficacy, but the pedestrian safety effects of temporary infrastructure are not well understood. This study tested the impact of temporary and permanent pedestrian infrastructure such as curb extensions/bump-outs and pedestrian medians/refuges as it relates to pedestrian and driver behavior. Twelve intersections in Minneapolis and Saint Paul, MN, comprising a mixture of intersection traffic control types and pedestrian infrastructure were examined before and after installation of the infrastructure. Staged pedestrian crossings by research staff at crosswalks examined driver stopping behavior and analyzed video data from installed traffic cameras to examine natural pedestrian behavior. A computer algorithm processed the video data to estimate vehicle speeds at the sites. For signalized intersections, the use of flexible delineators as a curb extension led to a reduced likelihood of drivers stopping for pedestrians during staged crossings. Little to no effect was found for permanent curb extensions at signalized intersections, perhaps due to the role that increased physical separation and visual complexity plays in the likelihood of drivers stopping for pedestrians. For unsignalized intersections, both temporary and permanent curb extensions were found to have similar and mixed effects for pedestrian safety when considering average driver speed, stopping likelihood, and pedestrian behavior. Both permanent and temporary medians had generally positive effects for the pedestrian safety measures, especially for average driver speed. Future research should closely examine the relative pedestrian safety impacts of temporary and permanent refuges at signalized intersections.Craig, Curtis M.; Morris, Nichole L.; Katariya, Vinit; Tabkhi, Hamed.

State of North Minneapolis Report
No full textThe history of North Minneapolis has influenced its current state of development and as it continues moving forward, members of the community and local stakeholders need a shared understanding of the current status of economic development in North Minneapolis. Destination Northside Coalition, a group of organizations committed to the long-term economic prosperity of North Minneapolis, empowered the capstone team to create a report that will serve as a resource to inform residents of North Minneapolis and visitors to the area that may not be aware of what economic development activity is in progress and planned within the community. The State of North Minneapolis Report explores ongoing and planned economic development projects and initiatives in North Minneapolis and identifies and evaluates what barriers are limiting further development in the area. These projects and initiatives were assessed through interviews, observation, and secondary research to determine how they align or conflict with comprehensive economic development strategies for North Minneapolis, specifically the Minneapolis 2040 Plan and the Northside Forward Plan. The degree of alignment and key barriers are captured in themes on economic development strategy, residential landscape changes, financial and economic constraints, and political and community-level challenges. The culmination of this work is presented in recommendations that focus on supporting local developers, mitigating the negative impacts of large-scale development projects, bridging the gap between resident and business needs with planning visions, and fostering cross-sector collaboration
