A Case Study In Evolving Academic Governance: Democratic Accountability And Academic Capitalism, William C. Schulz, Denise Dezolt

Higher Learning Research Communications

As the higher education market becomes both more competitive and fragmented (as well as controlled through uncertain and changing regulatory regimes), and as those whom the higher education market serves become more discerning as consumers who apply proven customer behaviors within the market, universities must re-evaluate their internal governance systems. Re-evaluation of customer behaviors and governance systems may allow universities to become more inclusive, responsive, and adaptive within an academic capitalism setting.

In this case study, we present a research-based and integrated “Shared, Informed, Stakeholder-Engaged Governance” model. We describe how a large online university developed and implemented a model that …

Functional Equivariance And Backward Error Analysis, Sanah Suri

Arts & Sciences Graduate Student Theses and Dissertations

Geometric, or structure-preserving, numerical integration has long been used as a framework for studying integrators that preserve a systems invariants. In backward error analysis, the approximate numerical flow of a system is viewed as the exact flow of a modified problem, allowing us to gain qualitative insights into the behavior of the numerical solution. The preservation of conservation laws by a numerical integrator can be generalized to $F$-functionally equivariant integrators, where $F$ represents an observable of the system in consideration. This thesis describes the behavior of geometric integrators through the lens of backward error analysis. First, we extend the idea …

The Role Of Cultural Humility In Enhancing Successful Intercultural Relationships, Felix Enyan

Research Papers

In the 21^st century, it is easy to locate a large group of population in U.S America. For society to thrive, a good intercultural relationship is a fundamental building block for societal advancement. However, individuals inherit cultural biases that discourages healthy intercultural relationships. Concepts like cultural humility aid in addressing the status quo. Cultural humility encourages lifelong learning and self-criticism of one’s view thereby acknowledging inherent bias. To remedy the status quo, cultural humility is introduced to intercultural communicators and individuals engaging in intercultural relationships.

A Multidimensional Preclinical Investigation Of The Biogenic Amine Depletion And Subchronic Swim Models Of Fibromyalgia, Cassie M. Argenbright, Ian F. Scully, Damaris Flores, Perry N. Fuchs

Psychological Science Faculty Publications

Pain is a multidimensional phenomenon, encompassing affective-motivational, cognitive-evaluative, and sensory-discriminative domains. Understanding these components is crucial for effective diagnosis and management, particularly in conditions like fibromyalgia (FM), where pain is of unknown etiology. However, attempts to replicate FM through preclinical models often fail to replicate the disorder’s multidimensionality. These studies evaluated the multidimensionality of two primary preclinical FM models—biogenic amine depletion(reserpine) and subchronic swim stress—across all three pain dimensions, and these models assessed predictive validity using the FDA-approved pharmacologic duloxetine (Cymbalta®). Additionally, the combinations of these models assessed whether their integration better mirrors clinical manifestations. The biogenic amine depletion model …
