The Spiritual Faith Journey of Hope College
Get PDFOver 150 years ago, Hope College was founded with a vision to become a “school of the prophets.” Philip Phelps and Albertus Van Raalte established an institution that would train ministers, pastors, missionaries, and inspirational men and women to carry the Gospel of Jesus Christ to the ends of the earth and to advance His kingdom revolution worldwide. Over the course of the past 150 years, Hope has endured seismic structural and spiritual changes that at times caused the school to wander away from its true goal and in turn become a lost, nearly secularized college, unfaithful to its original founding vision. However, a massive spiritual revival in the 1990s resurrected Hope College from the shackles of spiritual decay and ruin and put Hope back on track as a college to equip world Christians in the soil of Hope. From June-August 2019, Reed Hanson and Trygve Johnson collaborated, with funding from the History Department, to research the Faith History of Hope College and to bring its storied spiritual past to life through quotes, interviews, and personal testimonies that make Hope an institution like no other
Interactions between 2D Halide Perovskite Materials and Methylamine
Get PDFHalide perovskites offer exciting potential as photovoltaic materials and simply as semiconductors. Specifically, their structural tunability has become of greater interest as researchers begin to search for novel ways to tune the materials to achieve improved solar cell stability or to target new applications. One potential technology which halide perovskites could enable is dynamically switchable photovoltaic windows, windows which a user can transition between photovoltaically active (dark) and non-photovoltaic (transparent). We build toward this goal in this work by investigating the intercalation and deintercalation of methylamine gas into 2-dimensional Ruddlesden-Popper phase halide perovskites. As has been shown with methylammonium lead iodide films, the intercalation of methylamine into the halide perovskite lattice results in a color change to a clear crystal phase. We find that in some 2-D perovskite systems, deintercalation of the methylamine gas is incomplete, resulting in the formation of some CH3NH3PbI3; however, other 2-D perovskite phases show reversible intercalation/deintercalation with methylamine, indicating stronger binding between the long-chain ligand and the lead halide octahedra of the 2-D perovskite sheet. When integrated into a hybrid 2-D/3-D structure of the type A’2(CH3NH3)nPbnI3n+1, where A’ is a strongly binding R-NH3+ moiety such as phenethylammonium (PEA), these materials show promising reversibility for methylamine intercalation/deintercalation with little change in absorption or morphology. This work reveals the relative affinity of various R-NH3+ molecules for the halide perovskite lattice, showing that many of these are not replaced by methylamine, and indicates that templating the 3-D CH3NH3PbI3 structure with long-chain ammonium cations could lead to better reversibility in dynamic photovoltaic windows
The Anchor: September 2, 2020
Get PDFThe 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.

Ecohydrological Changes in Interdunal Wetlands/ Slacks as a Response to Rising Lake Levels in an Evolving Eolian Landscape along Lake Michigan’s Eastern Coast
Get PDFWe are conducting ecohydrological studies in mature and incipient interdunal wetlands/slacks in a coastal dune complex on Lake Michigan’s eastern coast. The slacks are located in the Saugatuck Harbor Natural Area, ~200m inland of Lake Michigan within a large parabolic dune (main slack) and smaller blowouts on its arms (incipient slacks). Rising Lake Michigan water levels have increased groundwater levels, monitored at twelve locations, \u3e1m, rewetting the main slack from its previous dry state, expanding its extent, and deepening pools. Adjacent blowouts now have incipient slacks with pools up to .5m deep. The main slack is dominated by Cladium mariscoides and Spiraea tomentosa with deeper pools having Carex lacustris, C. aquatilis, and Juncus species. The incipient slacks have a microbial mat and are sparsely vegetated with Juncus balticus and J. brachycephalus. Pool water chemistry and vegetation indicate the slacks are minerotrophic fens. We analyzed groundwater and surface water samples from the main and incipient slacks for pH and dissolved oxygen (DO) in summer 2019. pH and DO values in the slack pools increase overall from morning to late afternoon and decrease in the evening, suggesting a photosynthetic influence. Incipient slack pools typically have higher DO and pH values than mature slack pools, potentially indicating that algae populations in incipient pools have a greater influence than in mature pools. Incipient slacks also lack a decaying vegetation reservoir to depress oxygen values. Seasonal differences in surface water pH and DO values were noted as pH values were lower in May than July. Cool spring temperatures delayed photosynthesis and the accompanying removal of carbonic acid from the water, keeping pH values low. Rising temperatures increased photosynthesis, removing carbonic acid from the water and adding oxygen to it. This decreased pH and raised DO values
Hope College Abstracts: 19th Annual Celebration of Undergraduate Research and Creative Activity
Get PDFThe 19th Annual Celebration of Undergraduate Research and Creative Activity was held online on April 17, 2020. The event featured student-faculty collaborative research projects presented remotely due to the COVID-19 pandemic. This program is a record reflective of those projects between the 2019-2020 academic year. Not all research in this document was presented at the online event

The Role of Group Pride, Sympathy, & Guilt in Changing Privileged Groups\u27 Views of Racism
Get PDFThere’s a large gap between the way many Americans (especially Caucasians) and ethnic minorities perceive racism and the reality of experiencing racism. Among many Caucasians, there is a pervasive norm that race and racism are no longer a problem, yet 74% of Blacks polled in 2009 said they were personally discriminated against because of their race (Reid & Foehls, 2010). The goal of this study was to extend prior theory on group emotions to a new domain. We tested whether creating group pride, guilt, and sympathy influenced perceptions of racism in people who belong to a privileged group (Caucasians). We used prior manipulations that created feelings of group pride, sympathy, or guilt (Harth, Kessler, & Leach, 2008) to see if Caucasians perceive racism in the situation and allocated resources to the disadvantaged group. We predicted that (1) people feeling group pride would not perceive the situation as racism and (2), in contrast, people feeling group guilt or sympathy would perceive the situation as racism. We also examined whether these emotions affected other behaviors (e.g., compensating the disadvantaged group, perceiving other situations as discrimination). We also tested whether personality traits (e.g., political affiliation, gender) predicted perceptions of racism. We asked 141 Caucasian students in our experiment to read about inequality in hiring in Black and White workers, while they were in one of our three manipulated conditions. They then indicated their emotions, decided if the racial inequality reflected racism, decided whether to compensate Black workers, and indicated whether many other situations reflected discrimination. Preliminary results supported many of the predictions
