How Does Childhood Trauma Increase The Risk Of Developing Depression In Adulthood?, Ella Heydmann

Psychology Student Publications

Childhood trauma is a common but often overlooked experience that can leave lasting effects on psychological and biological development. Research shows that exposure to abuse or neglect in early life can alter the brain structure, stress-response systems, and emotional regulation, which can increase vulnerability to depression and anxiety in adulthood. Furthermore, evidence suggests that the impact of trauma may reach across generations through behavioral mechanisms. Despite these risks, resilience and protective factors, such as early intervention, can minimize long-term consequences and help promote recovery. Understanding these mechanisms is crucial for developing effective prevention strategies to reduce the lasting effects of …

On Lethality: Toward A More Complete Definition And Formation Of The Lethality Framework, John M. Hinck, Robert S. Hinck, Jayson A. Altieri, David R. Jarnot

The US Army War College Quarterly: Parameters

This article argues lethality should be conceptualized as a holistic and regenerative process in which adversarial militaries prepare for, adapt to, and sustain the application of force in conflict. Whereas the literature on lethality is widening to include the human war fighter, attempts to define and measure lethality have proven problematic—a struggle this article seeks to remedy. Drawing on historical, doctrinal, and interdisciplinary perspectives, the authors argue that lethality includes the capacity to kill and elements of learning and adaptation. The proposed lethality framework offers policy and military practitioners a model for assessing and operationalizing lethality in military education, leadership …

The Influence Of Endocrine Disrupters On Gut Microbiota, Kader Ugur

Expansion Limits Of Meshed Split-Thickness Skin Grafts, Haomin Yu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Split-thickness skin grafts are widely used to treat chronic wounds. Procedure design requires surgeons to predict how much a patch of the patient's own skin expands when it is meshed with rows of slits and stretched over a larger wound area. Accurate prediction of graft expansion remains a challenge, with current models overestimating the actual expansion, leading to suboptimal outcomes. Inspired by the principles of mechanical metamaterials, we developed a model that distinguishes between the kinematic rearrangement of structural elements and their stretching, providing a more accurate prediction of skin graft expansion. Our model was validated against extensive data …

Development Of A Multispectral Collagen Detection Dermatology Device For Delineation Of Non-Melanoma Skin Cancers, Anmol Jarang

McKelvey School of Engineering Graduate Student Theses & Dissertations

To diagnose and manage skin disease, clinicians primarily use visual inspection aided with dermatoscopes, which are cross-polarized magnifiers. In recent years, digital cross polarized multispectral imaging systems have been developed to quantitatively assess skin disease. For example, systems like the one developed by Yaroslavsky et al., which utilize red and blue filters, can non-invasively assess the collagen network in the dermis(Yaroslavsky et al., 2003). Visualization of collagen network disruption can make it easier to visualize the boundaries of skin cancers like keratinocyte carcinoma, and therefore easier to excise completely. Current systems use external bandpass filters in front of cameras to …

Trauma-Informed Training And Practices For Elementary School Lunchroom Supervisors, Heather C. Kostohryz

Dissertations, Theses, and Projects

School lunchrooms often see behavior disruptions at a higher rate than other areas within a school. Of the numerous reasons as to why, the inadequate training of those who supervise the lunchroom can be remedied easier than other factors (Wheatley et al., 2009). Over the past ten years a growing recommendation is for all staff to be included in school-wide behavior management and training, and that the training be focused on trauma-informed practices as a way to aid all students (Nealy-Oparah & Scruggs-Hussein, 2018). As 68% of children will experience some form of trauma during childhood, it stands to reason …
