Design Thinking For Health Environments: Case Study Research On Innovation, Design Leadership, And Healthcare Complexity, Diana S. Nicholas

Antioch University Dissertations & Theses

As healthcare costs are skyrocketing, of the 6,093 hospitals in America, 53% will lose money in the current year (Coleman-Lochner, 2022). Design health innovation centers (DHICs) are formed in Europe and the United States to create efficiencies in healthcare related to budget challenges. DHICs exist in unique contexts both in America and Europe that are not yet well understood. These efforts are difficult to lead due to the lack of understanding of their worth and how their process is valuable to healthcare settings (Bhattacharyya et al., 2022). The specific problem examined here is that little is known about how DHIC …

Beyond Strong: A Phenomenology Of Women Executives And The Connection Between Leadership And Fitness, Nozomi Bullock

Antioch University Dissertations & Theses

Senior-level executive leaders’ work in a dynamic, competitive, 24/7 business environment can be physically rigorous, mentally demanding, and emotionally isolating. The same holds true for women pursuing senior-level leadership roles in corporate America. Women who achieve and succeed in such roles remain the minority: Outsiders in elite spaces who are held to higher standards and overly scrutinized. Among senior-level executive women leaders, those committed to a fitness and training regimen including weightlifting constitute an even smaller minority. Senior-level executive roles require stamina, resilience, and courage—qualities that make up the foundation of the mindset of fitness and strength training (Foyster et …

Childhood Aggression: A New Conceptualization, Hannah G. Harrison

Childhood aggression is a frequently observed behavioral phenomenon, yet lacks a precise
definition in both the DSM-5-TR and current research literature. Definitional ambiguity and
construct enmeshment continue to create construct confusion for researchers, clinicians, and
informants. This empirical review of the current literature and diagnostic criteria examines how
childhood aggression has been historically conceptualized, defined, and described. The primary
aim was to identify and clarify inconsistencies in current definitions and to address knowledge
gaps to improve diagnostic clarity. Through a thematic synthesis of recent literature, several key
issues emerged: the absence of a precise definition of childhood aggression; reliance on …

Embracing The Suck: Overcoming Moral Injury-Related Attachment Trauma Through Outdoor Adventure, Emerald D. Ralston

Antioch University Dissertations & Theses

Moral injury is increasingly recognized as a distinct and debilitating consequence of military service, arising when individuals engage in, witness, or are unable to prevent actions that transgress their deeply held moral beliefs. In this dissertation, I argue that this form of trauma can be experienced as an attachment rupture, particularly when the military—functioning as an institutional attachment figure—betrays the servicemember’s trust. Such experiences compromise internal working models (IWMs) of self, others, and the world, and may result in complex trauma symptoms, including dissociation, depersonalization, and profound relational disconnection. These injuries are frequently stored in the body, rendering traditional cognitive …

Protein Marker-Dependent Drug Discovery Targeting Breast Cancer Stem Cells, Ashley V. Huang, Yali Kong, Kan Wang, Milton L. Brown, David Mu

Department of Biomedical and Translational Sciences Faculty Publications

Breast cancer is one of the most common cancers globally. Unfortunately, many patients with breast cancer develop resistance to chemotherapy and tumor recurrence, which is primarily driven by breast cancer stem cells (BCSCs). BCSCs behave like stem cells and can self-renew and differentiate into mature tumor cells, enabling the cancer to regrow and metastasize. Key markers like CD44 and aldehyde dehydrogenase-1 (ALDH1), along with pathways like Wingless-related integration site (Wnt), Notch, and Hedgehog, are critical to regulating this stem-like behavior of BCSCs and, thus, are being investigated as targets for various new therapies. This review summarizes marker-dependent strategies for targeting …

Gramseq-Dta: A Grammar-Based Drug-Target Affinity Prediction Approach Fusing Gene Expression Information, Kasul Debnath, Pratip Rana, Preetam Ghosh

Computer Science Faculty Publications

Drug–target affinity (DTA) prediction is a critical aspect of drug discovery. The meaningful representation of drugs and targets is crucial for accurate prediction. Using 1D string-based representations for drugs and targets is a common approach that has demonstrated good results in drug–target affinity prediction. However, these approach lacks information on the relative position of the atoms and bonds. To address this limitation, graph-based representations have been used to some extent. However, solely considering the structural aspect of drugs and targets may be insufficient for accurate DTA prediction. Integrating the functional aspect of these drugs at the genetic level can enhance …

Computer Science Faculty Publications

Estimating the transmission fitness of SARS-CoV-2 variants and understanding their evolutionary fitness trends are important for epidemiological forecasting. Existing methods are often constrained by their parametric natures and do not satisfactorily align with the observations during COVID-19. Here, we introduce a sliding-window data-driven pairwise comparison method, the differential population growth rate (DPGR) that uses viral strains as internal controls to mitigate sampling biases. DPGR is applicable in time windows in which the logarithmic ratio of two variant subpopulations is approximately linear. We apply DPGR to genomic surveillance data and focus on variants of concern (VOCs) in multiple countries and regions. …

Cath-Ddg: Towards Robust Mutation Effect Prediction On Protein-Protein Interactions Out Of Cath Homologous Superfamily, Guanglei Yu, Xuehua Bi, Teng Ma, Yaohang Li, Jianxin Wang

Computer Science Faculty Publications

Motivation: Protein-protein interactions (PPIs) are fundamental aspects in understanding biological processes. Accurately predicting the effects of mutations on PPIs remains a critical requirement for drug design and disease mechanistic studies. Recently, deep learning models using protein 3D structures have become predominant for predicting mutation effects. However, significant challenges remain in practical applications, in part due to the considerable disparity in generalization capabilities between easy and hard mutations. Specifically, a hard mutation is defined as one with its maximum TM-score < 0.6 when compared to the training set. Additionally, compared to physics-based approaches, deep learning models may overestimate performance due to potential data leakage.

Results: We propose new training/test splits that mitigate data leakage according to the CATH homologous superfamily. Under the constraints of physical …
