A Novel Hybrid Robust Transfer Learning-Based Adaptive Fractional-Order Super-Twisting Sliding Mode Controller Enhanced For Speed Regulation Of Brushless Dc Motor, Seyyed Morteza Ghamari, Asma Aziz, Daryoush Habibi

Research outputs 2022 to 2026

Brushless DC (BLDC) motors are widely used in applications that are highly-efficient, reliable, and compact, such as electric vehicles, robotics, and medical devices. However, the inherent nonlinearities and load sensitivity of BLDC motors require a robust and adaptive control strategy to ensure satisfactory performance under various operating conditions. Sliding mode control (SMC) has been widely used for the BLDC drives. However, because of its simplicity and robustness, the control effectiveness of the control is limited by the sensitivity to the disturbances and the chattering phenomenon. To remedy this, super-twisting (ST) technique has been proposed to achieve smoother response and better …

Shedding Light On Cellular Glycolysis Pathway Kinetics: Combining Kinetic, Mechanistic Modelling Approaches With Label Free Microspectroscopic Imaging. (Spectralomics), Nitin Patil

Doctoral

Cellular metabolism and its intricate biochemical mechanisms which allow the conversion of nutrients into energy to sustain life are well understood, leading to numerous breakthroughs in science and technology, human health and wellbeing. From an industrial perspective the pathway kinetics are significant for monitoring cellular bioprocesses, screening desired metabolite phenotypes in drug discovery processes, etc.

An initial review of glycolysis pathway kinetics highlighted the lack of sophisticated approaches to monitor the metabolic pathway kinetics as a function of time in a non-destructive, non-invasive, label-free manner. Fluxomics, a metabolomics based approach providing high-throughput insights, can be considered a gold standard approach, …

Proximate analysis quantified moisture, protein, ash, fiber, fat, and carbohydrate content, whereas GC-MS/MS and ICP-MS were employed to profile volatile compounds, FAMEs, and mineral elements. Carbohydrates were the predominant macronutrient (73.88%–74.21%), …

Open Contacts Adjacent To Posterior Dental Implants: Current Understanding And Emerging Preventive Concepts, Chiun-Lin Steven Liu, Shih-Cheng Wen, Ching-Jung Chang Chien, Je-Kang Du

Journal of Dental Sciences

Open proximal contacts between posterior dental implant restorations and adjacent natural teeth are a common yet underappreciated complication. This review examines the multifactorial etiology of open contact formation, including biomechanical discrepancies, prosthetic and surgical factors, occlusal force dynamics, and natural tooth migration. The clinical consequences-ranging from food impaction and gingival inflammation to proximal bone loss and diminished patient satisfaction-are also analyzed. These complications not only affected oral hygiene and comfort but might also contribute to peri-implant tissue breakdown and increased maintenance needs. Existing preventive and corrective strategies, such as prosthetic over-contouring, splinted restorations, and occlusal equilibration, are reviewed with attention …

The Silent Language Of Trauma: Defendant Behavior, Juror Bias, And Expert Testimony, Jensen Goldman

Scripps Senior Theses

Trauma can profoundly influence behavioral presentation, yet jurors often rely on demeanor as a diagnostic cue for guilt, credibility, and remorse. Such reliance poses risks within a legal system that seldom equips jurors to interpret trauma related behaviors accurately. The proposed study will examine how two trauma-linked affective presentations– overemotionality and flat affect– shape juror perceptions of credibility and guilt, and whether expert psychological testimony about trauma-related affect can mitigate these biases. Online survey participants will read one of five trial vignettes with varying defendant conditions (flat affect vs. overemotional) and varying expert testimony conditions (present or not present) and …

Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb

Psychology Faculty Publications

Emotion regulation refers to the processes through which people modulate their emotional experiences and expressions, and difficulties in these processes underpin many forms of psychopathology. According to the process model, emotion regulation encompasses five classes of strategies, commonly grouped into antecedent-focused strategies (e.g., cognitive reappraisal) and response-focused strategies (e.g., expressive suppression). These strategies involve both explicit and implicit processes, which can be objectively assessed using physiological indices. The present study examined the effects of startle habituation and vagally mediated heart rate variability (vmHRV) on the use of cognitive appraisal and suppression. Forty-nine college-aged participants were recruited, and their resting heart …

Social Exclusion, Social Support, And Trauma, Eric D. Wesselmann

Faculty Publications – Psychology

Humans have an inherent need to forge stable and quality social connections. One key benefit of having social connections is obtaining social support for navigating traumatic or otherwise stressful events. Ostracism (i.e. being both ignored and excluded, Williams, 2009) and other forms of social exclusion rob individuals of the opportunity to receive social support and likely contribute to stress-related mental health concerns. My colleagues and I tested this premise in different stress-related contexts, ranging from college students struggling with potentially stigmatizing secrets to community members who have experienced various types of traumatic incidents (e.g., miscarriage, military combat). We examined the …

They Don't Talk Very Good: Attending To Raciolinguistic Socialization In Early Childhood, Erin Quast

Faculty Publications - College of Education

In this article, I share experiences from my roles as a teacher, researcher, and parent to show how raciolinguistic ideologies take hold in early childhood. Specifically, I illustrate how children come to uphold English superiority, map language to belonging, and make judgments about whose language counts. In sharing these experiences, I call on educators and caregivers to attend to raciolinguistic socialization and work toward disruption so that all children's languages are valued in literacy learning. I suggest centering multiple languages, cultivating curiosity, and questioning curricular assumptions as ways to work alongside children in challenging hierarchies and creating learning spaces that …

The Retrograde Pendulum: Reversing Course On Standards-Based Grading, Jay C. Percell

Faculty Publications - College of Education

This commentary details one large, suburban school district that, after a decade-long commitment to implementing standards-based grading (SBG), reversed course, abandoned the initiative, and returned to traditional grading. This article provides a postmortem of the ambitious reform effort, drawing upon previous research and recent district survey data from teachers and parents. Among the factors leading to the reform's reversal are that, despite a carefully planned, multi-year rollout, the initiative was unable to resolve persistent concerns about implementation inconsistency, student motivation, and the technology reporting platform. Internal pressures were exacerbated by external turmoil, including personnel turnover and the COVID-19 pandemic, and …

Teacher Agency: Finding Spaces To Transform Ela Classrooms, Kathryn Mitchell Pierce, Carol Gilles, Sarah D. Reid

Faculty Publications - College of Education

Amid ongoing attacks on teachers and their professionalism, we studied three middle school ELA teachers who exercised their agency to transform their classrooms and curricula through social justice pedagogy (SJP). Using Pantić's (2017) model, we examined their sense of purpose, competence, autonomy, and reflexivity in confronting barriers. This multiple-case study drew on interviews, focus group transcripts, artifacts, and responses to our analysis of their reported beliefs regarding their agency about dialogic talk in literature discussions as part of SJP. We found that teachers' agency, dialogic talk, literature discussions, and SJP were deeply interwoven. Teachers valued dialogic talk in literature discussions …

We’Re The Aunties Now: Intersections Of Mourning Practices, Intergenerational Trauma, And Matrilineal Responsibility In Oneida Life, Marena Bridges

Antioch University Dissertations & Theses

This dissertation examines how Oneida and broader Haudenosaunee mourning practices, as I have lived and understood them, shape grief, healing, and matrilineal responsibility in my family. Using Indigenous autoethnography and storywork, I first present a crafted narrative, then return to that narrative through reflexive thematic analysis. The analysis identifies patterned meanings in how grief is structured, shared, and carried across closely stacked deaths in the maternal line. Mourning practices function as community infrastructure that organizes time, redistributes labor, transmits knowledge, and sustains continuing bonds with the dead. At the same time, repeated loss produces a form of matriarchal ascension, concentrating …

The Conservation Value Of Silvicultural Systems For Breeding And Post-Fledging Bird Communities In Northeastern North America, Christopher Andrew Liazos

Antioch University Dissertations & Theses

Forest bird community decline in the eastern United States is partly due to the lack of early-and-late-successional forests stemming from historic land use. Silviculture can create underrepresented forest age classes and structures to support avian communities during the breeding and post-fledging periods. In southwestern New Hampshire, we conducted a case study evaluating avian conservation value indices across silvicultural systems. Our goal was to observe how avian conservation value indexes and abundance differed between recently managed and unmanaged stands. We surveyed 215 breeding and 118 post-fledging points across 22 sites using point counts and vegetation surveys. Conservation values in the breeding …

The purpose of this study is to understand and explore the phenomenon of the rupture, reckoning, and when possible, the repair process with racial, ethnic, and cultural (REC) microaggressions in counselor education. Participants (n = 14) included counselor educators who had either enacted a REC microaggression and attempted repair, or had been the recipient of an REC rupture and a meaningful attempt at repair. This study utilized a thematic analysis as a methodological framework in interpreting the data with the perspective of borderlands theory, critical embodied phenomenology, relational cultural theory and relational neuroscience analytical frameworks to account for and explain …

One Tree, Many Roots: A Care-Centered Cultural Philosophy Of Education For Collective Flourishing, Darshini Margaret Elizabeth Stark

Antioch University Dissertations & Theses

Public education in the United States is often framed as a neutral pathway to opportunity, democratic participation, and individual success. Yet for many students, particularly those from historically marginalized communities, schooling has functioned as a site of self-abandonment, where compliance means survival. This dissertation argues that persistent educational harm is not the result of individual curriculum failure or isolated policy shortcomings, but something far more insidious: the intentional use of schooling as a mechanism of political control and socioeconomic hierarchy, shaped over centuries by authoritarian governance and colonial ideology. In response, this work advances Oru Maram (Stark, in preparation) as …

Decolonizing Teacher Mindsets With Precolonial Worldview Precept Reflection And Transformation, Gabriela Armendariz

Antioch University Dissertations & Theses

Colonial education systems, rooted in Western epistemologies, have perpetuated a legacy of settler colonialism that continues such problems as environmental disconnection, inequality, and power dynamics that disadvantage marginalized and Black, Indigenous, People of Color (BIPOC) communities. While decolonizing education has generally been about critically examining how entrenched colonial practices shape curricula, teaching methods, and institutional policies, the emphasis of my proposed study is a focus on contrasting precolonial (Indigenous) worldview precepts, using the contrasting but non-dualistic worldview chart created by Four Arrows and Darcia Narvaez (Wahinkpe Topa [Jacobs], 2024). In partnership with K-12 educators from major school districts across the …

The Impact Of The Covid-19 School Shutdown On Standardized Test Scores In Rural And Nonrural Areas, Cory Laflamme

Antioch University Dissertations & Theses

The novel Coronavirus of 2019 (COVID-19; Gillings School of Global Public Health, n.d.) caused an extensive disruption of education systems worldwide. Elementary and secondary schools began to close to students and staff to protect them from potential exposure to the virus (Masonbrink & Hurley, 2020). Nearly 1.6 billion students in over 200 countries had their learning impacted on some level, causing changes in traditional educational practices (Pokhrel & Chhetri, 2021). One profound change in educational practice was the shift from face-to-face learning to online learning alternatives. Using the State of New Hampshire data allowed for a unique analysis of how …

The Effect Of Paternal Engagement On The Sexual Self-Concept Of Black Female Adolescents, Amelia Flynn

Antioch University Dissertations & Theses

Black women in the U.S. continue to experience disproportionately high rates of unintended pregnancies, with a 64% rate reported in 2011 (Finer & Zolna, 2016). Positive sexual self-concept (SSC) is linked to healthier sexual behaviors, yet research on SSC development has largely overlooked the role of fathers and systemic influences, particularly within Black families. Grounded in an ecological framework, this study examines the impact of father-daughter engagement on SSC among Black female adolescents, considering paternal residential status and socioeconomic class as key contextual factors. The study revealed that when middle class father-daughter engagement is high, daughters’ sexual self-esteem is lower. …

Assessing Use Of Invasive Understory Plant Species By The Eastern Box Turtle (Terrapene Carolina Carolina) Within A Massachusetts Wildlife Management Area, Karoline Weston

Antioch University Dissertations & Theses

Eastern box turtles are facing population declines across their range due to habitat loss, vehicular strikes, and illegal collection. A lesser-explored aspect of eastern box turtle conservation is the role of non-native, invasive vegetation in shaping fine scale habitat use. Invasive vegetation can alter habitat structure and quality, yet its role in eastern box turtle behavior remains unstudied. To evaluate this relationship, I tracked 19 eastern box turtles via radio telemetry throughout the 2022 active season in a Massachusetts wildlife management area. My study addressed six questions: (1) Do eastern box turtles exhibit a preference for microhabitats containing invasive vegetation? …

Through The Eyes Of A Daughter: Blues City Cultural Center And The Black Arts Movement, Ayana Williams

Antioch University Dissertations & Theses

This creative dissertation examines the Blues City Cultural Center (BCCC) as a living continuation of the Black Arts Movement in the American South. Founded in Memphis, Tennessee, in 1979 by Deborah Frazier and Levi Frazier, Jr., BCCC emerged from the cultural and political momentum of the Black Arts and Black Power Movements and continues to sustain their principles through original theater, community-based arts education, and grassroots cultural organizing. Challenging the notion that the Black Arts Movement is a concluded historical period, this study argues that the movement remains ongoing, adaptive, and deeply embedded within Southern Black communities. Using a creative …
