Colby College 1820-1925: An Account of Its Beginnings, Progress and Service

The definitive history of Colby College's first century.

The Strider Years: An Extension of the History of Colby College

Beloved Colby historian Ernest Cummings Marriner '13 documents Robert E. Lee Strider's nineteen years as president of Colby College. Marriner is also the author of the definitive History of Colby, which covers the period up to the Strider presidency.

Declining foreign enrollment at higher education institutions in the United States : a research note

When the Institute of International Education reported a drop of 2.4% in international student enrollment in the United States in 2003/2004, the first absolute decline in foreign enrollments since 1971/1972 (Open Doors, 2004), many were quick to point fingers at visa policies instituted after the September 11, 2001 attacks. The "Visas Mantis" review—a security clearance required for foreign students studying any of roughly 200 scientific fields—was blamed for tarnishing the view of the United States as a welcoming place for international students. Although the review has certainly been the cause of increased visa delays and rejections, this article takes the view that it is not the only cause for the dip in foreign enrollments in the United States. Through econometric analyses, it is shown that other than the visa quagmires, improved access to domestic education opportunities and tuition fee increases can indeed explain the drop in foreign enrollments.

Wind Turbine Visibility on the Colby Campus

This project was designed to demonstrate the visibility of potential future wind turbines built on the Colby campus. We conducted viewshed analyses in ArcGIS on three different potential turbine sites to determine the visibility of the turbines within a 10km radius. We found that the Runnals hill turbine would be visible to the largest area and the largest number of residents.

Light Coverage on Colby College Campus

Outdoor lighting is an essential component for nighttime safety on college campuses. Outdoor lighting on Colby College campus is not uniform, leaving some areas with minimal light. The purpose of this project is to analytically evaluate if and where major walkways on Colby College have inadequate lighting. While we were unable to define inadequate lighting, we found that most paths on campus do appear to be well lit, while in general open spaces on campus have the lowest light levels.

Solar Panel Modeling on Suitable Roofs at Colby

With the recent construction of Colby Green and the current plans for the construction of several new buildings, the total area for future development on campus has declined. The goal of this study was to illustrate existing campus development and to determine where future growth could occur. GIS was used in determining the different soil systems on campus, the current use of the land, and the boundaries of the Colby property. The project shows what potential obstacles the college will have in attempting to expand the campus and proposes where the best options are for construction.

Developing a Model for Pedestrian Route Selection at Colby

Millions of unconscious calculations are made daily by pedestrians walking through the Colby College campus. I used ArcGIS to make a predictive spatial model that chose paths similar to those that are actually used by people on a regular basis. To make a viable model of how most travelers choose their way, I considered both the distance required and the type of traveling surface. I used an iterative process to develop a scheme for weighting travel costs which resulted in accurate least-cost paths to be predicted by ArcMap. The accuracy was confirmed when the calculated routes were compared to satellite photography and were found to overlap well-worn “shortcuts” taken between the paved paths throughout campus.

Spatial Analysis of Colby College Trails: Perkins Arboretum and Runnals Hill

I created an updated map of trails at Colby College using global positioning system data that were then edited in ArcGIS. The map background, obtained from the Maine Office of GIS, was created from digital orthophotographs produced from aerial photos collected over southwest Maine in Spring 2003. Trail difficulty was determined by creating a slope layer and taking other factors into consideration such as ground surface and path width. The map will eventually be available online, enabling interactive selection of trails where users can access additional trail information.

A Spatial Analysis of Impervious Surfaces at Colby College in 1965 and 2006

Roads, parking lots, buildings, and other impervious surfaces do not allow rainwater to infiltrate the ground. As a result, they can lead to an increase in runoff to nearby ditches and streams, as well as a greater influx of pollutants such as motor oil that can often be found on paved surfaces. For this project, GIS was used to find the total area covered by impervious surfaces on the Colby campus, and to show how this area has grown in the past 40 years. It was found that new development on the campus has lead to a 56% increase in impervious surfaces at Colby since 1965.
