Discrete time models, one linear and one non-linear, are investigated, both with a herbivore species that consumes a basal food source species. Results are presented for coexistence of the species and to illustrate chaotic behaviour as parameters are varied in the non-linear model. The results indicate the benefit of fertilization in terms of the…

The hanging rope problem is considered. The rope is subject to rotation with the rotation axis being parallel to the rope. Using a continuum model and the basic principles of dynamics, the differential equation governing the motion is derived. The dynamic equilibrium case without vibrational motion is assumed in deriving the equation. The equation…

The relationship between central and academic units can cause tension within an institution as there is a desire to define ownership over activities, policies, and processes associated with enrollment management (e.g., recruitment, admissions, academic scheduling). This article proposes a new enrollment planning model that can be used to navigate…

In this article, we outline the work of using the Sustainable Development Goals (SDGs) in graduate leadership education for sustainability (GLES). We identify how the SDGs can serve as an effective operationalization of the concept of sustainability, propose a framework of GLES, provide specific examples of the use of the SDGs in graduate…

Mathematics provides us with tools to capture and explain phenomena in everyday biology, even at the nanoscale. The most regularly applied technique to biology is differential equations. In this article, we seek to present how differential equation models of biological phenomena, particularly the flow through ion channels, can be used to motivate…

The Piazza Center Horizontal Hazing Model conceptualizes the ways in which hazing transitions from pre-college environments into higher education and across student constructed spaces such as student organizations or sorority and fraternity chapters. Hazing is multi-tiered, occurring at individual, organizational, and community levels. This model…

Developing an adequate understanding of the nature of science includes developing an understanding of the uses and importance of models in science. General accounts of science aimed at university students, however, tend to neglect this aspect. A noticeable exception is the simple model of the key elements of a scientific result presented by Giere,…

The paper delineates three elements of an entrepreneurial university in practice through innovations demonstrating the academic entrepreneurial transition: the "Novum Trivium," Professors of Practice (PoPs) and Link initiatives. The "Novum Trivium" provides a model for the integration of entrepreneurship into a liberal arts…

In this Methods Showcase Article, we illustrate mixed-effects modeling with a multinomial dependent variable as a means of explaining complexities in language. We model data on future-time reference in second language Spanish, which consists of a nominal dependent variable that has three levels, measured over 73 participants. We offer step-by-step…

The Appreciative-Based Change (ABC) Model of Community Engagement focuses on strengthening partnerships and maximizing impact by using an appreciative approach to service-learning while addressing the challenges of community-university partnerships. The model offers phases that identify and leverage unified strengths, assets, and resources to…

Tutoring promotes student achievement, academic independence, and the reduction of anxiety. While ample studies support tutoring for enhancing student success, few address how to evaluate tutoring. This quandary led to research in building and testing a meta-model that identified the hallmarks of one-on-one high-quality online tutoring.…

Who 'owns' student success at an institution of higher education? Which unit is responsible for student outcomes? The answer to those questions at most universities is complicated. The evidence-based programmes, processes and interventions institutions implement to bolster student success are rarely 'communications' initiatives, but they all…

Obtaining a degree from a community college is a strong pathway to numerous career opportunities for students from low-income backgrounds. Unfortunately, graduation rates from community colleges are often very low, so many students do not reap the benefits of a degree. With the goal of increasing graduation rates, three community colleges in…

While technical communication consultants and researchers agree that content strategy requires attention to both customer needs and business goals, we found no evidence that technical communication educators promote an accurate understanding of business goals among their content strategy students. Through industry-academia collaboration, we…

Universities face an uncertain funding environment and turbulent marketplace. Financial scenario modelling offers a potential mechanism to assist in navigating a way forward. Our previous paper on UK universities' practice found some variation in the sophistication of the approaches taken, but the overall impression was of a relatively simple…
