Stifled Voices: World War Ii From The Upper Peninsula, Elijah H. Croschere

HS 390 Primary Research Papers

Academic scholarship on World War II is primarily based around letters and correspondence between soldiers and their families. A large body of such correspondence exists for both the Upper and Lower Peninsulas of Michigan; yet, most scholarship on the state’s connection to World War II is centered around strictly the Lower Peninsula. This is especially strange when comparing the data on enlisted soldiers from both Peninsulas, as we find the percentage of the population who enlisted in the US Army from the Upper Peninsula is roughly double that of the percentage for Lower Peninsula enlistments. There are clear reasons as …

Using Stable Isotope Analysis To Investigate The Trophic Ecology Of Aquatic Insects, Shelby Ann Medlock

Master's Theses

Despite their abundance on the landscape, ponds and associated macroinvertebrate assemblages have largely been underrepresented in scientific studies, which usually focus on lakes or streams. Similar to other waterbodies, ponds can harbor high levels of invertebrate biodiversity, which is important as aquatic insects are experiencing declines due to habitat destruction, pollution, climate change, and invasive species introductions. To evaluate how these threats impact pond insects and the ecosystem services they may provide, a thorough understanding of their ecology is essential.

Developing Humanistic Clinicians: A Review Of Literature, Andrew Taylor, Willie Capers

The Journal of the Research Association of Minority Professors

Humanistic clinicians possess scientific and technical competence and demonstrate essential virtues like empathy, compassion, patience, love, and courage. Humanistic clinicians are trained with an emphasis on the sciences and the humanities. The humanistic clinician is therefore better equipped to care for patients, the patient’s family members, other clinicians, and themselves. Defining empathy can be problematic due to a lack of consistent definition. Relevant literature regarding empathy was reviewed before settling on a working definition. Several pedagogical approaches encourage the moral development of clinicians. The methods and purpose of those approaches are explained. Illness narratives or pathography is a particular type …

Noncoincidence In The Brothers Karamazov, Stewart Justman

Global Humanities and Religions Faculty Publications

The intricate plot of The Brothers Karamazov turns upon conjunctions of events which, on inspection, turn out not to be coincidental. Only by probing the often-subtle connections between events can we appreciate the implications of actions and failures to act in this astonishing work. The Brothers Karamazov tells not of a mysterious power called Coincidence that orders human affairs, but of the responsibilities of human agents, and its wonder lies not only in philosophical excurses like the Grand Inquisitor episode, which seem to transcend its pages, but in the complexity of its own construction.

A Review Of The Ripple Effect Of Parental Incarceration: Suggestions For System Improvement From Neonatal Development Through Adolescence, Karen Thew, April Terry

International Journal of Undergraduate Research and Creative Activities

Parental incarceration has the potential to drastically affect the social, behavioral, and physical lives of children. Such negative impacts include prenatal and chronic health conditions, behavioral and mental health issues, developmental delays, juvenile and criminal legal system involvement, and overall declines in well-being. These damaging outcomes occur for babies delivered during their mothers’ incarceration with negative lingering effects seen throughout the lifespan. Due to the stigmatization of incarceration, these children may experience bullying, engage in isolating behaviors, and struggle within the school, which may lead to the school-to-prison pipeline. While prevention and intervention services directed at these youth could not …
