Global Dynamics Of A Mutualism–Competition Model With One Resource And Multiple Consumers, Yuanshi Wang, Hong Wu, Donald L. Deangelis
Global Dynamics Of A Mutualism–Competition Model With One Resource And Multiple Consumers, Yuanshi Wang, Hong Wu, Donald L. Deangelis
United States Geological Survey: Staff Publications
Recent simulation modeling has shown that species can coevolve toward clusters of coexisting consumers exploiting the same limiting resource or resources, with nearly identical ratios of coefficients related to growth and mortality. This paper provides a mathematical basis for such as situation; a full analysis of the global dynamics of a new model for such a class of n-dimensional consumer–resource system, in which a set of consumers with identical growth to mortality ratios compete for the same resource and in which each consumer is mutualistic with the resource. First, we study the system of one resource and two consumers. …

This report provides Portland State University’s (PSU) Campus Sustainability Office (CSO), with an objective third party LEED O+M Materials Assessment of PSU’s University Services Building (USB). The data collected for this audit provides CSO with insight into the building’s current waste composition and diversion rate. Additionally, it identifies opportunities to reduce the amount of recoverable materials ending up in the landfill stream. Community Environmental Services (CES) conducted material audits for 100% of USB’s landfill-bound, commingled recycling, and compost streams during a 24-hour period. While, audited construction and demolition (C&D) materials were generated over the course of a week.

In this report, both occupant comfort perception-based data, collected via surveys, and building performance-based data, collected via sensors, are utilized to conduct a post-occupancy evaluation of Portland State University’s (PSU) new Karl Miller Center (KMC), formerly known as the School of Business Administration. The KMC was completed in September 2017 and is on track to earn LEED Platinum certification, primarily for the passive ventilation strategies incorporated into its design. The environmental factors studied in this report are air and concrete slab temperatures, CO2 levels, and airflow. The personal factors studied in this report are clothing levels (clo), gender identity, thermal …

Campus Sustainability Office Publications, Reports and Presentations
The Campus Sustainability Office (CSO) compiles information from departments across campus annually to complete the STARS Report. The score is based on the number of points received across five categories: Academics, Engagement, Operations, and Planning & Administration, and Innovation & Leadership. PSU has maintained a Gold rating since the institution began reporting in 2011 and is within the top 40 of over 400 reporting institutions. This summary includes improvement opportunities to assist our efforts to eventually become a STARS Platinum institution. For more information on improvement opportunities please contact Amanda Wolf at wolf@pdx.edu
