Supporting pollinators in agricultural landscapes: a technical guide for specialty crop growers in the U.S. Midwest
No full textThe Midwest is an agriculturally important part of the U.S., and many high-value specialty crops grown in the region require pollination by bees and other pollinators. This Technical Guide is designed for specialty crop farmers in the U.S. Midwest who want to protect and support pollinators on their land. While it’s not a comprehensive manual for pollinator management, this Guide offers practical ideas for getting started and encourages continued exploration of best practices. Actions that support pollinators improve farm productivity as well as the resiliency of agricultural operations and the environment. This guide goes in depth on several key areas of pollinator protection, including: Integrated Pest Management (IPM), pollinator habitat creation and maintenance, communication with beekeepers, and pesticide product selection and use. It also explores marketing opportunities related to pollinator conservation such as product labeling, price premiums, and agritourism, and provides a step-by-step template for developing a pollinator management plan and budgets. Finally, the Guide includes research highlights, resource links, and case studies to help farmers implement and adapt pollinator-friendly practices on their farms.University of Minnesota College of Food, Agricultural and Natural Resource Sciences.Grinstead, Andy; Lievers, Reed; Morandin, Lora; Redfield, Phoebe; Wilson, Cody; DiGiacomo, Gigi; Hutchison, Bill; Illes, Molly; Lee, Katie; Schuh, Marissa; Wimmer, Madeline; Ziegler, Ben.

What does It mean to be an evaluator? a mixed-methods exploration of American evaluators' professional identity.
No full textUniversity of Minnesota Ph.D. dissertation. March 2025. Major: Organizational Leadership, Policy, and Development. Advisor: John LaVelle. 1 computer file (PDF); xii, 179 pages.A clear sense of professional identity is critical for the development of evaluation as a profession, providing practitioners with a solid frame of reference upon which to base work decisions and improving society’s understanding of and trust in this field. This dissertation research draws from fields outside of evaluation to examine individual- and collective-level professional identity in order to inform the field’s discourse regarding what its practitioners believe it means to be an evaluator. The process of the study involved gathering data on evaluators’ sense of belonging, attachment, commitment, beliefs, and experiences with the evaluation profession, analyzing it qualitatively and quantitatively to develop a holistic understanding of evaluators’ professional identities. The results suggest that evaluators’ professional identities are grounded in affective and philosophical domains as demonstrated by the relationships between self-identification and commitment variables and by the implied and explicit feelings and values expressed throughout survey responses and interviews. The findings also demonstrate the unique nature of evaluation as a transdiscipline and question whether traditional professionalization paradigms are appropriate for its study and development.Espelien, Doris.

Self-Selected Diets: Exploring the Factors Driving Food Choices and Satisfaction with Dietary Variety July 2024
No full textLiking had the greatest influence on food choice. Liking increased satisfaction with variety. Convenience reduced satisfaction with variety.Food choices determine the nutrients and other substances that build and maintain our bodies as well as consumer demand for food products. People choose specific foods, and those choices are strongly influenced by many factors. Our goal was to examine the reasons participants gave for choosing each of the foods they consumed during a 4-week study, how those influencers differed for different food classes, and whether the influencers predicted satisfaction with their dietary variety.This research was supported in part by the National Aeronautics and Space Administration (NASA; NNX12AE56G), the Minnesota Agricultural experiment station project MN-18-081, and the Sensory Center at the University of Minnesota Department of Food Science and NutritionEhrmantraut, Lauren; Mann, Traci; Redden, Joseph; Helwig, Nathaniel; Vickers, Zata.

Thirty-five years of intimate partner homicide discourse by Minnesota’s statewide domestic violence coalition, 1989-2023
No full textUniversity of Minnesota Ph.D. dissertation. May 2025. Major: Social Work. Advisor: Lynette Renner. 1 computer file (PDF); xv, 309 pages.Dozens of Minnesotans are killed every year in intimate partner homicides (IPH).Minnesota’s statewide domestic violence coalition (SDVC) is the only entity to systematically collect and present data on this social issue through their annual IPH reports. How a social issue is framed impacts the way the issue is understood by policymakers and the public, influencing how and to what extent the social issue is addressed. IPH is often mischaracterized in the news media in the United States, and little research has been conducted around how other policy actors, like SDVCs, frame IPH in their social issue discourse. Thus, this study used case study methods to better understand thw changes to Minnesota’s SDVC’s framing of IPH as a social issue over time, and what micro, mezzo, and macro factors may have influenced those changes. Analysis was conducted across multiple data sources: the 35 annual IPH reports published by Minnesota’s SDVC, the SDVC’s archival collection from the University of Minnesota Social Welfare Archives, timeline mapping of sociohistorical events, and qualitative interviews with nine of the report authors. Within-case and cross-case analyses were employed. The study identified the key change to the IPH reports over time as a shift from a mainstream feminist frame with a criminal legal focus to an intersectional feminist frame with a public health orientation. Report authors were identified as the most frequent and strongest influences to changes to the IPH reports, within the context of a collaborative organizational structure at the SDVC that aligned with feminist organization principles. Additional within-case and cross-case changes and influences are presented, and implications for future framing of IPH as a social issue in Minnesota are discussed.Dorman, Amy. (2025).

Enhancement and Validation of a Stormwater Pond Assessment Tool
No full textThe Pond Assessment Tool (beta version) is a spreadsheet-based tool that was originally developed for the evaluation and management of stormwater ponds, as part of the Janke et al. (2023) study assessing phosphorus retention in stormwater ponds and wetlands treating stormwater runoff. The Tool was developed to provide pond managers with a toolbox to evaluate ponds in a straightforward and inexpensive manner. The Tool can perform screening and assessment of stormwater ponds at risk of poor phosphorus performance using readily available spatial, water quality, and pond data, thereby providing a low-cost method for assessing a large number of stormwater ponds for phosphorus water quality functionality. The original version of the Tool, however, was not validated.
The primary objective of this project was to update and validate the original version of the Pond assessment Tool, so that conditions indicative of poor phosphorus retention in ponds, i.e., high TP, low dissolved oxygen, and high sediment phosphorus release, could be evaluatedWater Resources Center and the Minnesota Stormwater Research CouncilNatarajan, Poornima; Janke, Benjamin D.; Finlay, Jacques C..

Perfectoid algebras and the almost purity theorem
No full textUniversity of Minnesota M.S. thesis. May 2025. Major: Mathematics. Advisor: Kai-Wen Lan. 1 computer file (PDF); ii, 35 pages.This thesis focuses on the study of perfectoid algebras and their significance in proving the almost purity theorem, an important result in p-adic Hodge theory. We begin with the foundations of non-archimedean analysis and perfectoid fields, providing illustrative examples, and introduce the framework of almost mathematics. We then develop the theory of perfectoid algebras in detail. Using tools such as the cotangent complex, we present a proof of the tilting equivalence between K-perfectoid algebras and K♭-perfectoid algebras, following Scholze’s approach. Finally, leveraging this equivalence, we derive the almost purity theorem for perfectoid fields.Tian, Jiaxi. (2025). Perfectoid algebras and the almost purity theorem.

Synthesis of peptide-based small molecule probes to study redox status and protein prenylation.
No full textUniversity of Minnesota Ph.D. dissertation. February 2025. Major: Chemistry. Advisors: Edgar Arriaga, Mark Distefano. 1 computer file (PDF); viii, 60 pages.The use of solid phase peptide synthesis to produce molecular probes for chemical biology applications is an efficient and tunable process allowing for the synthesis of tools for a wide range of applications. The modular nature of peptide synthesis makes it relatively simple to change features of a probe to suit whatever needs are necessary. The sidechains of the amino acid building blocks serve as convenient handles for the addition of fluorophores or other tags.
In this thesis, peptides are used as building blocks to make a redox probe and several analogues of an internally quenched Ste24p cleavage probe. I also examine the consequences of solid phase synthesis, specifically racemization, when cysteine is the C-terminal residue. The synthesis of the redox probe was modified to improve the ease of its production. The internally quenched Ste24p cleavage probe was applied to show that C-terminal modifications of the probe do not appear to influence the cleavage kinetics of the Ste24p protease.Boyle, Elyse.

Remote newsrooms: the place and labor of digital news production.
No full textUniversity of Minnesota M.A. thesis. April 2025. Major: Mass Communication. Advisor: Matt Carlson. 1 computer file (PDF); iv, 117 pages.This study offers a systematic qualitative exploration of the perceived impact of remote work on news workers’ professional experiences in the U.S. news industry. It describes the experiences of news production situated digitally, socially, spatially, and temporally by combining labor process theory, Gieryn’s concept of place, and Braverman’s (1974) time management concept. This study presents findings from 30 in-depth interviews with news workers throughout the U.S. during pivotal moments of the coronavirus pandemic between 2021 and early 2022. Findings describe how working remotely influenced the experience of news production through digital technology, professional socialization, place, and time. Overall, these findings present an increasingly professionally dominated work-life balance within news work, contributing to labor intensification and an internalized panopticon The conclusion encourages a closer exploration of internalized labor control and labor intensification to better prepare future news workers for professional precarity.McMullen Cheng, Rowan.
