Self-Care Night at the Kruizenga
A poster for a self-care night hosted by Hope College\u27s Students Teaching and Empowering Peers (STEP) and Women\u27s Empowerment Organization (WEO) on April 12, 2018.https://digitalcommons.hope.edu/kam_poster/1032/thumbnail.jp
A Model of Motor and Sensory Axon Activation in the Median Nerve Using Surface Electrical Stimulation
Surface electrical stimulation has the potential to be a powerful and non-invasive treatment for a variety of medical conditions but currently it is difficult to obtain consistent evoked responses. A viable clinical system must be able to adapt to variations in individuals to produce repeatable results. To more fully study the effect of these variations without performing exhaustive testing on human subjects, a system of computer models was created to predict motor and sensory axon activation in the median nerve due to surface electrical stimulation at the elbow. An anatomically-based finite element model of the arm was built to accurately predict voltages resulting from surface electrical stimulation. In addition, two axon models were developed based on previously published models to incorporate physiological differences between sensory and motor axons. This resulted in axon models that could reproduce experimental results for conduction velocity, strength-duration curves and activation threshold. Differences in experimentally obtained action potential shape between the motor and sensory axons were reflected in the models. The models predicted a lower threshold for sensory axons than motor axons of the same diameter, allowing a range of sensory axons to be activated before any motor axons. This system of models will be a useful tool for development of surface electrical stimulation as a method to target specific neural functions
Effect of Acute Ingestion of a Cup of Coffee on 5-Km Running Performance in Collegiate Cross- Country Athletes
Previous research has shown that various forms of caffeine can enhance exercise performance in many activities. However, the vast majority of prior studies have examined effects of caffeine in pill form, rather than from a cup of coffee. Specifically, the effect of a low dosage of caffeinated coffee on 5-km running performance has not yet been studied in depth. Therefore, the purpose of this study was to determine the effect of ingestion of twelve ounces of caffeinated coffee on 5-km performance in Hope College male and female cross-country runners. Ten participants were brought in for a familiarization trial, which included taking baseline measurements and a 2-km timed treadmill run after drinking twelve ounces of water. Following familiarization, participants were divided into two groups matched for best 5-km time, and a double-blind crossover design was used. All participants abstained from caffeine for at least 12 hours before each trial. One group consumed 12 oz of caffeinated coffee before the 5-km treadmill time trial the first week, while the other group consumed 12 oz of decaffeinated coffee before the trial. The following week, the groups consumed the alternate treatment. At the completion of each kilometer, time, HR, and RPE were recorded. Trials occurred seven days apart on the same day of the week, at the same time of day, and diet and physical activity were mimicked before each trail. It was hypothesized that the 5-km completion time after caffeinated coffee consumption would be significantly faster than when decaffeinated coffee was consumed. Significant results would allow for the recommendation of caffeinated coffee consumption before cross-country races for college aged runners. This study is ongoing, and results will be available during the poster presentation
Having the Number They Want: Empowerment of Latin American Women
Empowerment, an individual’s ability to exercise authority and control over their life, can be expressed in a variety of ways. One indicator of empowerment affecting women is their ability to have their ideal number of children. However, culturally imposed gender roles may pose a barrier to women’s empowerment. In Latin American culture, machismo promotes hyper-masculinity and Marianismo encourages women to embody the Virgin Mary. This study assessed the relationship between empowerment of Latin American women and their ability to have their ideal number of children. Empowerment was measured with respect to educational, economic, social, and contraceptive domains using Demographic Health Survey data (N = 25,996) from Colombia (n = 12,458), Guatemala (n = 7,168), and Honduras (n = 6,370). A series of Analyses of Covariance (ANCOVA) tested indicators of women’s empowerment with respect to their number of living children while controlling for their ideal number. Education was a significant means of empowerment in all three countries studied, as women with higher levels of education had fewer children. Economic decision-making was significantly related to the number of children for women in Guatemala and Honduras. Colombia, the wealthiest country, had no significant findings in the economic domain. Social empowerment, however, was particularly powerful there (e.g., making healthcare decisions). Colombian and Honduran women with knowledge of contraceptives reported having fewer children. Findings can be used to empower women in country-specific programs. Educational programs would serve as a means of empowerment for women in all three countries. Programs with an emphasis on contraceptive education would benefit women from Colombia and Honduras, while social programs would be most relevant for women from Colombia. Guatemalan and Honduran women stand to benefit from both social and economic empowerment programs. Overall, the goal is to increase women’s independence and ownership of decision-making in their lives

The Anchor, Volume 132.05: October 3, 2018
The Anchor began in 1887 and was first issued weekly in 1914. Covering national and campus news alike, Hope College’s student-run newspaper has grown over the years to encompass over two-dozen editors, reporters, and staff. For much of The Anchor\u27s history, the latest issue was distributed across campus each Wednesday throughout the academic school year (with few exceptions). In recent years The Anchor moved to monthly print issues and a more frequently updated website. The Anchor is now published in print twice per academic semester. Occasionally, the volume and/or issue numbering is irregular

Pallist: Find Nearby Friends
This project worked with the Ready For Life Program at Hope College in order to help its students more confidently find familiar faces when they find themselves alone in a public place. Our work resulted in the construction of an iPhone app, Pallist, which allows Ready For Life students to create connections with fellow iPhone users and see which of these other users is nearby. Our app was customized for Hope College students by designing it to sense when a user is in a specific building on campus and then showing the location of fellow users that are inside this same building. When outdoors, users are considered “nearby” when they are within 50 m. of each other. Ready for Life students will be able to use our app to independently navigate new social settings with the confidence that they will be able to locate someone they know
