Escape behavior of the Grammostola rosea tarantula and Phidippus regius spider in response to heat stimuli

Insects respond to aversive stimuli such as wind, looming and heat by escaping in a direction opposite the stimuli. Spiders have 8 legs, which offers the spider more gait options for escape than insects, which have 6 legs. However, there are few published studies on the escape response of spiders, and there is no information that shows how location or direction of the stimulus will affect escape patterns. Therefore, the specific goal of my research was to determine the relationship between the stimulus location and direction of response in two species of spider – Regal Jumping spiders (Phidippus regius) and juvenile Chilean Rose tarantulas (Grammostola rosea) - for heat stimuli delivered to the spider’s eight tarsi (legs). Results show that spiders will always move away from the heat stimulus. Additionally, spiders will translate (movement of the center of mass without turning) almost directly away from the stimulus without turning. The initial position of the leg does not affect response, demonstrating that there is no proprioceptive feedback (feedback on where the body is in space) when exposed to aversive heat stimuli

Trauma Recovery on College Campuses

With the support of REBOOT Recovery, this capstone was completed to bridge the gap between college students who have experienced traumatic events and the lack of tier two services available on Cleveland State\u27s Campus. The goal of this capstone was to show the efficacy of REBOOT Recovery\u27s programming as well as show improvements in overall quality of life.https://engagedscholarship.csuohio.edu/ot_capstone_posters/1023/thumbnail.jp

Polygamy is creepy, wrong, and sick! (however, I find it fascinating) : parasocial comparison, parasocial processing, parasocial contact hypothesis, and polygamy

This dissertation examined tolerance of polygamists as a result of exposure to television programming. Specifically, it looked at how audiences form attitudes toward the practice of polygamy and its participants in light of viewing its portrayals in popular television entertainment. Using historical research, semi-structured interviews, surveys of viewers and students, and an experiment, I explored the issue of tolerance among different types of Americans. The findings in these studies demonstrate that Americans never cared for polygamy and continue to find little appeal for its practice. Yet, we are captivated by television shows that focus on polygamy. Part of our habit of tuning in is related to how we process portrayals of individual polygamists; we compare ourselves with them, sometimes upwardly or downwardly, and may build parasocial bonds with them through our screens. I found strong support for the parasocial contact hypothesis, and argue that with positive portrayals over time, viewing individual characters in such shows could erode the sense of “divergence” we feel as a result of our unfamiliarity with the practice. On the other hand, negative and even mixed portrayals of polygamists can reinforce our existing stereotypes and prejudices

Microfluidic Syntheses of PET Radiotracers via Fluorodenitration

This research study is focused on the syntheses of radiotracers for use in positron emission tomography [PET] via fluorodenitration and fluorodehalogenation under microfluidic conditions. Methodology has been developed for radiolabeling via fluorodenitration under microfluidic conditions and comparisons made to dehalogenation reactions. Developmental work was carried out on commercially available compounds containing a variety of functional groups. Subsequent production of radiotracers has been performed with precursors provided by collaborators as well as those synthesized in our laboratory

204 - How does change in land use impact the water chemistry parameters in the streams of Oswego County, NY

Land use within a watershed is closely tied to stream water chemistry. Anthropogenic chemical inputs eventually make their way into streams, affecting fluvial ecosystems. Sources of these anthropogenic inputs change over time, especially when rural landscapes become increasingly urbanized. We studied the relationship between land use and stream water chemistry for Oswego County, New York, because riparian zones in this county have shifted to residential from agricultural and forested land uses. We extracted data from the New York State Department of Conservation (DEC) Department of Water (DOW) Monitoring Portal. Preliminary results show that Total Nitrogen (Kjeldahl) in mg/L fluctuates yearly from 2001-2020, Total Nitrogen in mg/L increased by 0.29 mg/L from 2009 to 2020, and Total Phosphorus decreased slightly from 2001 to 2015. Changes in land use do not appear to be substantial enough to have a large impact on these chemical parameters in Oswego County. However, the data collected for sites in Oswego County are sparse, and thus our results may be misleading. We will conclude with recommendations to Oswego County for a sampling strategy that better encompasses the major waterways of the county
