Minerva 2010, The Honors College

Minerva

This issue of Minerva celebrates the 75th anniversary of Honors at the University of Maine! It includes an article on the college's 75th anniversary celebration; a look into the inaugural Center for Undergraduate Research (CUGR) symposium; and discussions on 2010 Honors Read, Persepolis, as well as 2011 Honors Read, The Omnivore's Dilemma. Other highlights include an article on Honors graduate and historian, Kristen Gwinn, and her book Emily Greene Balch: The Long Road to Internationalism.


When Bad Stress Goes Good: Increased Threat Reactivity Predicts Improved Category Learning Performance, Shawn W. Ell, Brandon Cosley, Shannon L. Mccoy Nov 2010

When Bad Stress Goes Good: Increased Threat Reactivity Predicts Improved Category Learning Performance, Shawn W. Ell, Brandon Cosley, Shannon L. Mccoy

Psychology Faculty Scholarship

The way in which we respond to everyday stressors can have a profound impact on cognitive functioning. Maladaptive stress responses in particular are generally associated with impaired cognitive performance. We argue, however, that the cognitive system mediating task performance is also a critical determinant of the stress-cognition relationship. Consistent with this prediction, we observed that stress reactivity consistent with a maladaptive, threat response differentially predicted performance on two categorization tasks. Increased threat reactivity predicted enhanced performance on an information-integration task (i.e., learning is thought to depend upon a procedural-based memory system), and a (nonsignificant) trend for impaired performance on a …


The Growth, Yield, And Financial Performance Of Isolated Eastern White Pine (Pinus Strobus L.) Reserve Trees, Christopher E. Zellers Aug 2010

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 …


Rule-Based Categorization Deficits In Focal Basal Ganglia Lesion And Parkinson’S Disease Patients, Shawn W. Ell, Andrea Weinstein, Richard Ivry Jun 2010

Rule-Based Categorization Deficits In Focal Basal Ganglia Lesion And Parkinson’S Disease Patients, Shawn W. Ell, Andrea Weinstein, Richard Ivry

Psychology Faculty Scholarship

Patients with basal ganglia (BG) pathology are consistently found to be impaired on rule-based category learning tasks in which learning is thought to depend upon the use of an explicit, hypothesis-guided strategy. The factors that influence this impairment remain unclear. Moreover, it remains unknown if the impairments observed in patients with degenerative disorders such as Parkinson’s disease (PD) are also observed in those with focal BG lesions. In the present study, we tested patients with either focal BG lesions or PD on two categorization tasks that varied in terms of their demands on selective attention and working memory. Individuals with …


Assessing Sleep Quality In Young Adult College Students, Aged 18 - 24 In Relation To Quality Of Life And Anthropometrics, Douglas Mathews May 2010

Assessing Sleep Quality In Young Adult College Students, Aged 18 - 24 In Relation To Quality Of Life And Anthropometrics, Douglas Mathews

Electronic Theses and Dissertations

Little is known about the impact of sleep on quality of life and anthropometrics in young adults. College students (n=218) were recruited through a variety of methods for a study on weight management for obesity prevention and randomized into control (n=108) or treatment (n=110) groups. Of those, 152 (71%) completed pre- and post-tests, including the Pittsburg Sleep Quality Index (PSQI), scored 0-4 =normal and 5-21=disordered, (a=0.80), the General Health Questionnaire-12 (GHQ), scored from 0-14=good quality of life to 15-36=poor quality of life, (ct=0.87), and anthropometrics. Statistical analyses included linear regression, one way ANOVA, chi-square analysis, and Pearson's Product-Moment Correlation. Significance …
