Population Growth Models: Relationship Between Sustainable Fishing And Making A Profit, James Sandefur

CODEE Journal

In this paper, we develop differential equations that model the sustainable harvesting of species having different characteristics. Specifically, we assume the species satisfies one of two different types of density dependence. From these equations, we consider maximizing sustainable harvests. We then introduce a cost function for fishing and study how maximizing profit affects the harvesting strategy. We finally introduce the concept of open access which helps explain the collapse of many fish stocks.

The equations studied involve relatively simple rational and exponential functions. We analyze the differential equations using phase-line analysis as well as graphing approximate solutions using Euler's method, …

Creators For The Earth: The Academic Library’S Role In Supporting Sustainability Creators And Practitioners Across All Disciplines, Jennifer K. Embree, Neyda V. Gilman

Library Scholarship

The image of a creator often brings to mind individuals that can take an abstract or unique idea and transform it into an impressive, tangible creation. Whether it’s an architect crafting a new building design, an artist painting on canvas, or an interior designer mapping out a new room layout, creators are generally seen as those who can formulate conceptual ideas that are then realized to showcase amazing ingenuity. In the world of higher education, this type of work is often first associated with disciplines like art, design, architecture, and engineering—fields where acts of “making,” “creating,” or “building” are integral …

Streaming With Butterflies: A Whole School Stream Project, Carey L. Averill, Janet M. Herrelko

Journal of Catholic Education

This study explores the commitment of a school faculty to use the pedagogical practices needed to employ a project-based unit of Science, Technology, Religion, Engineering, Arts, and Mathematics (STREAM). The unit of study concentrated on environmental sustainability of butterflies through project-based learning (PBL). Teacher interviews were analyzed to reveal the similarities and differences, strengths and weaknesses in the teachers’ reactions to implementing a cross-curricula content unit designed for a pre-kindergarten (PK) to eighth grade school. Analysis of teacher data and classroom artifacts provided evidence of: content mastery at the student levels; implementation of scaffolding for developmental levels; and the need …
