Recyclable Phase-Anchored Silylation Reagents

Chlorosilanes are common protecting groups. However, in use, they introduce an extra step and after use they are discarded. As part of an effort to make these species’ use greener, we have been exploring effective ways to efficiently isolate silyl-protected species and to recycle and regenerate trialkylsilylchlorides after the protecting group is removed from its substrate. Prior work in the Bergbreiter group has shown that attaching a highly nonpolar group to molecules makes them selectively soluble in nonpolar solvents. This selective solubility allows such phase-anchored species to be separated from the reaction mixture with a biphasic extraction. We have extended this work to silyl species showing that a chlorosilane with a long alkyl chain, octadecyldimethylchlorosilane can make silylated species phase-selectively soluble. This was shown by allowing octadecyldimethylchlorosilane to react with several primary alcohols to form dimethyloctadecylsilyl ethers. These ethers were placed in a DMF/cyclohexane solvent system where they showed >96% retention of the silylated alcohols in the nonpolar phase. Octadecyldimethylchlorosilane was also used as a protecting group in a palladium-catalyzed cross-coupling reaction. In this case, the silylated product could be removed from polar phase soluble catalyst residues by a simple extraction, avoiding a waste generating chromatographic purification step. To further improve phase-selectivity, we replaced the octadecyl group with PIB, a soluble polymer support. PIB-chlorosilane was synthesized using hydrosilylation and chlorination reactions and ongoing work involves removing unreacted PIB with a PEG protection and precipitation. Octadecyldimethylsilyl triflate, a Lewis acid catalyst, was also synthesized

Comparisons of College Students’ Enjoyment in Physical Activity & Exergames

The purpose of this study was to compare college students’ enjoyment levels in three domains of activity (traditional physical activities, exergames, and non-exergames). Volunteers (n = 141) from a Midwestern university completed an online survey composed of a modified version of the Physical Activity Enjoyment Scale (PACES). Significant differences were detected across the three domains regarding level of enjoyment, F(2, 232) = 32.49, p < .001, with the highest enjoyment levels reported in the traditional physical activity domain. Additional results revealed that Wii Sports (49%) and Just Dance (29%) had the highest percentage of use with exergamers, while non-exergame participants reported playing video games such as Pokémon, Zelda, Mario Kart, Madden (59%), and Clash of Clans (25%). These results suggest that traditional physical activities and exergaming activities are psychologically enjoyable pursuits for college-aged individuals that can help increase their physical health and quality of life

College Students\u27 Length of Time and Canine/Handler Interactions at Drop-In Canine Therapy Program

Drop-in canine-therapy programs on college campuses have grown rapidly in the United States (Crossman & Kazdin, 2015). These drop-in programs are meant to help students decrease stress, anxiety, and homesickness while increasing well-being and mood (Grajfoner, Harte, Potter, & Mcguigan, 2017; House, Neal, & Brackels, 2018). Though there is initial research on the effects of animal therapy on individuals (Binfet, Passmore, Cebry, Stuik, & McKay, 2017), the recency of this research area means there is a limited understanding of student motivation, experience, and preferred visit length. This research study aims to learn who attends, why they attend, and what students hope to gain from the experience, as well as the length of time and number of interactions students have with canines and handlers during a drop-in session. In order to address these aims, we will conduct survey and observational research during Hound Hugs & Kanine Kisses Program sessions. This poster will present initial data from only the observational research portion of this study. Observational data on students\u27 length of time at the event and number of interactions with therapy dogs and handlers will be collected. This information can help researchers understand the length of time and number of interactions participants naturally seek out during their visit (i.e., “dose-response relationship”). With the findings from this research, we hope to give supporting statistics as to how college students engage with the canines and handlers to help inform future programming on college campuses

A Preliminary Study of College Students’ Levels of Humility and Disability Attitudes

Color poster with text and charts.The purpose of this study was to explore college students' levels of dispositional and intellectual humility and the potential link between humility and disability attitudes. We predicted that those with higher levels of dispositional humility would have more positive disability attitudes. We believe this study is important for understanding various factors related to college students’ disability attitudes, particularly if humility is related to disability attitudes.University of Wisconsin--Eau Claire Office of Research and Sponsored Program

Perceptions of Anxiety, Attention Deficit/Hyperactivity Disorder, and Learning Disabilities

Color poster with text and charts.An increasing aspect of diversity in higher education is disability, with approximately 19% of college students reporting a disability. To promote full inclusion of students with disabilities, it is important to understand how disability is perceived. Various studies have demonstrated that disability is not always perceived positively by college students and these perceptions may impact the persistence and satisfaction of students with disabilities. Green found that college students tend to share a common perspective that feelings of sadness, pity, and awkwardness are often felt towards students with disabilities. It is likely that multiple factors such as faculty attitudes, availability of services, campus culture, and peers’ attitudes and knowledge about disabilities are associated with students with disabilities satisfaction with their college experience. The Purpose of this study was to explore college students’ attitudes towards and knowledge of disabilities. By using an online Qualtrics survey methodology, college students’ attitudes towards and knowledge of three specific disabilities, namely anxiety disorder, Attention Deficit Hyperactivity Disorder (ADHD), and Learning Disabilities (LD) were examined.University of Wisconsin--Eau Claire Office of Research and Sponsored Program

College Students’ Experiences with Stress, Coping Mechanisms, and Awareness of the Physical Effects of Stress

Color poster with text, images, charts, and graphs.Stressful life events are inevitable. It is how we interpret and manage those events that determines the impact that they have on our bodies. Stress has been linked to negative consequences in each system in our body, including the endocrine, reproductive, gastrointestinal, and cardiovascular systems (American Psychological Association). Ample research has been done on types of stressors for college students. Few researchers have measured college students’ awareness of this topic and, consequently, we know little about their awareness of the physical effects of stress. By examining college students’ awareness of the physical effects of stress, in addition to their experiences with stress and various coping mechanisms, we can further understand the potential relationships among these variables.University of Wisconsin--Eau Claire Office of Research and Sponsored Program
