Orts 78, 2023
Get PDFThe main purpose of this edition of Orts is to give our George MacDonald Society members and friends early notice that registration for our 2024 George MacDonald Conference at Wheaton College has now gone live. You can see the current line up of Keynote Speakers on the registration page, and more speakers and participants will be added over the coming weeks. We have some exciting plans that we truly hope will make this a celebration worthy of George for everyone. We anticipate this event will prove popular and spaces are limited, so we would encourage you to take full advantage of the early bird discount rates. Look forward to meeting many of you there
The Relationship Between Procrastination and Mental Health
No full textMany college students experience procrastination at some point during their academic career. The present study sought to investigate the correlation between procrastination in college students and their reported levels of various negative mental health emotions, including anxiety, perceived stress, and depression. Whether or not a participant was considered a procrastinator was determined based on whether the participant completed the survey during the first five weeks of the semester or the last five weeks of the semester. Participants that completed the survey during the first five weeks were deemed non-procrastinators, while participants in the last five weeks were deemed procrastinators. This assumption was supported by participants’ averaged scores on questions in a procrastination scale. Statistical analysis revealed that participants who completed the survey in the first five weeks of the semester reported a statistically significant lower average procrastination score than participants in the last five weeks. Using the average procrastination score for each participant, correlation analyses demonstrated a weak, positive correlation between procrastination score and reported anxiety scores. Additionally, analyses demonstrated a moderate, positive correlation between procrastination score and perceived stress as well as depression scores. While these analyses cannot demonstrate a cause-and-effect relationship between procrastination and mental health, they do demonstrate that, as procrastination increases, so does reported negative mental health. Therefore, the findings of this research may be important for a college student to considering when deciding whether or not to procrastinate.https://digitalcommons.snc.edu/collaborative_presentations/1112/thumbnail.jp
Physiological effects of artificial light at night on two cavity-nesting passerines
No full textArtificial light at night (ALAN) is a human-caused phenomenon that is disrupting the daily cycles of animals. Circadian disruption via ALAN, even at low levels, can disrupt development, behavior, and physiological function, including altered melatonin levels, increased secretion of glucocorticoids, decreasing body mass, and disrupting patterns of rest and arousal. However, in some cases, immunocompetency has increased in response to ALAN. The response to stress caused by ALAN may alter the energy budget of animals. We hypothesized that two demanding physiological responses, immunocompetency and telomere elongation, may compete for limited resources in developing birds. We tested this by exposing house sparrow (Passer domesticus) and tree swallow (Tachycineta bicolor) chicks to ALAN at a level of approximately 1 lux in nest boxes for five nights pre-fledging. We conducted E. coli bacterial killing assays on plasma and measured telomere lengths from DNA collected before and after exposure. As the nestlings aged immunocompetency increased, but we found no effects of ALAN exposure. Surprisingly, telomere lengths increased in response to ALAN in house sparrows. We will discuss the effects of ALAN on physiological trade-offs and compare outcomes between a declining native and successful invasive species.https://digitalcommons.snc.edu/collaborative_presentations/1107/thumbnail.jp

A low cost confocal microscope
No full textWe demonstrate a simple and cost-efficient scanning confocal microscope setup for use in advanced physics laboratories. Designed from convenient commercial products, the implementation a 3D printed flexure stage allows for further cost reduction. Experiments exploring the thickness of a microscope slide and the surface of solid objects with height variation are presented as foundational components of undergraduate laboratory projects and demonstrate the accuracy of the setup on the micron scale.https://digitalcommons.snc.edu/collaborative_presentations/1102/thumbnail.jp
