Getting To The Heart Of Social And Educational Disadvantage: Exploring The Impact Of Social Interactions Across The Class Divide, Ryan M. Pickering

Electronic Theses and Dissertations

Economic inequality between rich and poor in the United States is now at an all- time high. The increasing economic inequality in the United States may have deleterious effects for social interactions across the so-called “class divide.” Individuals from different socioeconomic status (SES) backgrounds may find cross-class interactions stressful or intimidating, particularly when they are from a lower-status group.

Across two studies, I examine the impact of cross-class social interactions on cognitive performance and physiological reactivity. In the first study, individuals from lower-SES backgrounds participate in a social interaction with an individual from either a higher or lower-SES background, or …

Park Aid Systems: Factors That Affect Consumer Purchase Decisions, Nadeesha Kushlanie Surasinha Thewarapperuma

Electronic Theses and Dissertations

Backover crashes in the United States result in at least 300 fatalities and 17,000 injuries every year. Backover crashes occur when a non-occupant of a vehicle is struck by a vehicle moving in reverse. Children are particularly vulnerable. Of the 300 fatalities, at least 100 deaths are children under the age of five. Limited visibility is one factor behind these deaths. The deaths are especially tragic, since the availability of a simple park aid device can expand a driver’s field of vision during a reversal maneuver. Park aid devices include a rearview camera or a sensory system.

The Growth, Yield, And Financial Performance Of Isolated Eastern White Pine (Pinus Strobus L.) Reserve Trees, Christopher E. Zellers

Electronic Theses and Dissertations

The ability of eastern white pine (Pinus strobus L.) to persist as emergent trees makes this species well suited to silvicultural systems in which they are retained as isolated reserves after a regeneration harvest. While such systems are implemented throughout the Acadian spruce-fir region of Maine, little is known about the growth response and financial performance of eastern white pine following complete release from competition. In this study, 77 trees from 8 sites throughout the Acadian spruce-fir region were sampled tree and crown measurements, and increment cores were extracted at breast height, as well as from the top of …
