    Consolidation, Competition, and Antitrust Law: A Changing Landscape for Minnesota Farmers
    (2024-05-01) Keliher, Matthew
    Much of the research on farming and agricultural market concentration focuses on the importance of quantitative elements such as price, access to markets or capital, or concentration ratios. And while these quantitative measurements are critical for understanding the impact consolidation has on consumers and producers within the broader agricultural industry, it only represents one aspect. This qualitative study aims to capture the perspectives of Minnesota farmers to explore how consolidated agriculture markets impact farmers’ communities and livelihoods. Comparing their perspectives with the current literature regarding market concentration in agriculture and food distribution, this study aims to illuminate the views of independent farmers that are subject to the control of dominant firms that abuse their market power. Semi-structured interviews with Minnesota farmers highlight key elements of the reviewed literature and demonstrate connections between challenges faced by farmers with economic indicators such high costs of farming inputs, the limitations of quality rural healthcare, and the burden placed on farming communities through restrictions on repairing agricultural equipment. A key theme throughout the interviews revealed that many farmers view consolidated industries as systems of control. Control over how they can farm, how they can care for and feed their livestock, how they can repair their machinery, where they can sell their produce and for how much. These systems of control are often hailed as “efficiencies” by consolidated corporate power. But for farmers, these systems of control represent an end to two things farmers and all citizens value most: creativity and liberty.

    Enhancement of learning: Does sleep benefit motor skill memory consolidation?
    (2010-12) Borich, Michael Robert
    Purpose: It remains unclear how the brain best recovers from neurologic injury and how to optimally focus rehabilitation approaches to maximize this recovery. Recent research has indicated that sleep may augment this recovery. Sleep has been shown to benefit memory consolidation for certain motor skills, but it remains unclear if this relationship exists for explicit, continuous, goal-directed motor skills with rehabilitation applications. We aimed to determine the neurobehavioral relationship between finger-tracking skill development and sleep following skill training in young, healthy subjects. Methods: Forty subjects were recruited to receive motor skill training in the morning (n=20) or the evening (n=20). Measures of skill and cortical excitability were collected before and after training. Following training, each group had a post-training interval consisting of waking activity or an interval containing sleep. After this twelve-hour interval, skill performance and cortical excitability were reassessed. Subjects underwent another twelve-hour interval containing either waking activity or a sleep episode and came back for a second assessment, twenty-four hours after training. A subset of subjects (n=10) underwent the same procedures except the training period involved simple, repeated movement of the finger. Results: Skill performance improved after training and then continued to improve offline during the first post-training interval. Improvement was not enhanced by sleep during this interval. Cortical excitability was not substantially altered by training but was related to level of skill performance at follow-up assessment. Sleep quality was also found to be related to level of skill at follow-up assessments. The skilled training period did not lead to significantly improved performance compared to simple movement activity. Discussion: These data suggest that sleep is not required for offline memory enhancement for a continuous, visuospatial finger-tracking skill. These findings are in agreement with recent literature indicating the type of motor skill trained may determine the beneficial effect of sleep on post-training information processing. These results, combined with related studies in patient populations, provide a foundation to evaluate the relationship between sleep, changes in neural activity, and the time course of continuous visuospatial motor skill learning in individuals following neurologic insult.
