Life Is Complicated: The Urgent Call To Support Student Wellbeing Through Social Emotional Learning, Taya Kinzie

Dissertations

Abstract:

Students face increased mental health challenges, including depression, anxiety, trauma, racial trauma, and suicide risk, in addition to opportunity gaps. Despite educators’ work to support students through mental health services and despite the existence of social emotional learning (SEL) programs within the school environment, the impact on student learning and long-term post high school outcomes can feel overwhelming. There is also a perception that the responsibility for SEL belongs only to social workers, psychologists and counselors. The primary research question is; how does embedding of SEL practices vary within instructional, non-instructional, and leadership roles? The related questions are: to …

The Necessity And Possibility Of Decolonizing The Understanding Of Chinese-Ness, Tao Zhang

Dissertations

In this dissertation, I explore how crossing national borders has made me aware of the many identity borders that I have crossed as a transnational Chinese, and how I am caught up in identity politics between the “Chinese,” who do not necessarily always identify as “Chinese” in the transnational context. However, as a racialized group in the U.S., transnational Chinese are perceived as a homogeneous population, usually through racially (“Yellow Peril” or “Chinese Virus”) and politically (“Red Scare”) charged lenses measured by Western/U.S. binaristic and hierarchical standards. Therefore, in this research project, I problematize dominant U.S. race logic, i.e., the …

Safe And Brave Spaces: What Comprises A Fruitful Multicultural Supervision Learning Environment?, Monica Becerra

Dissertations

Researchers continue to emphasize the important role supervisors have in creating a safe space for supervisees to effectively navigate and engage in honest multicultural conversations while also addressing potential biases (e.g., Ancis & Marshall, 2010). However, much of the literature on multicultural supervision provides limited guidance on what characteristics define a safe space. The purpose of this study was to examine accounts of counseling psychology graduate students to learn about their understanding and definitions of safe space and brave space within multicultural supervision, using grounded theory methodology (Corbin & Strauss, 2015). Specifically, the purpose of the study was threefold: (a) …

A Behavior Genetic Study Of Activity Levels And Internalizing Problems Across Childhood, Matthew Jamnik

Dissertations

This study used a twin and triplet sample to investigate the influence of preschoolers’ physical activity levels and internalizing problems on subsequent health outcomes (body-mass index, internalizing behavior problems, household health behaviors) in middle childhood. The potential influence of stressors salient in childhood (household chaos, socioeconomic status, stressful life events) on the hypothesized relationship between physical activity and internalizing on health was also explored. A specific focus was placed on examining the underlying genetic and environmental influences of children’s physical activity levels, as assessed by both temperamental (parent-reported) activity levels and observed (in-lab) motor behavior, using a behavioral genetic approach. …

The Interplay Of The Physical Landscape And Social Dynamics In Shaping Movement Of African Savanna Elephants (Loxodonta Africana), Maggie Wisniewska

Dissertations

Free ranging African savanna elephants (Loxodonta africana) are increasingly impacted by human-induced habitat loss and poaching for ivory. Because elephants live in tightly knit groups, this combination of threats not only reduces the size of their populations but also degrades their social interactions. Long-term relationships with socially competent individuals, such as experienced seniors, benefit the ability of other group members to access limiting resources and avoid danger. Understanding how anthropogenic pressure may affect persistence of elephant populations is important, because elephants are an economically important keystone species. This doctoral thesis characterizes how individual elephants influence the movement of their social …

Data-Driven Learning For Robot Physical Intelligence, Leidi Zhao

Dissertations

The physical intelligence, which emphasizes physical capabilities such as dexterous manipulation and dynamic mobility, is essential for robots to physically coexist with humans. Much research on robot physical intelligence has achieved success on hyper robot motor capabilities, but mostly through heavily case-specific engineering. Meanwhile, in terms of robot acquiring skills in a ubiquitous manner, robot learning from human demonstration (LfD) has achieved great progress, but still has limitations handling dynamic skills and compound actions. In this dissertation, a composite learning scheme which goes beyond LfD and integrates robot learning from human definition, demonstration, and evaluation is proposed. This method tackles …

Participatory Learning: Measuring Learning And Educational Technology Acceptance, Erick Sanchez Suasnabar

Dissertations

Participatory Learning (PL) integrates several learning approaches, engaging students throughout the entire assignment process for both online and face-to-face courses. Beyond simply providing a solution, students also craft a problem (problem-based learning), grade each other (peer assessment and feedback), evaluate themselves (self-assessment), and can view others’ work (learning by example). This dissertation research explores the resulting learning effects. Contributions to both educational and Information Systems research include extending an early PL model and experiments that applied the PL approach to examinations, by validating and testing new constructs based on user activity and critical thinking. In addition, the study explores a …

Towards Understanding The Role Of Central Processing In Release From Masking, Nima Alamatsaz

Dissertations

People with normal hearing have the ability to listen to a desired target sound while filtering out unwanted sounds in the background. However, most patients with hearing impairment struggle in noisy environments, a perceptual deficit which current hearing aids and cochlear implants cannot resolve. Even though peripheral dysfunction of the ears undoubtedly contribute to this deficit, surmounting evidence has implicated central processing in the inability to detect sounds in background noise. Therefore, it is essential to better understand the underlying neural mechanisms by which target sounds are dissociated from competing maskers. This research focuses on two phenomena that help suppress …

Learning Of Radar System For Target Detection, Wei Jiang

Dissertations

In this dissertation, the problem of data-driven joint design of transmitted waveform and detector in a radar system is addressed. Two novel learning-based approaches to waveform and detector design are proposed based on end-to-end training of the radar system. The first approach consists of alternating supervised training of the detector for a fixed waveform and reinforcement learning of the transmitter for a fixed detector. In the second approach, the transmitter and detector are trained simultaneously. Various operational waveform constraints, such as peak-to-average-power ratio (PAR) and spectral compatibility, are incorporated into the design. Unlike traditional radar design methods that rely on …

From Roundabout To Roundabout: Tahrir Square (1869- 2021), Mariam Abdelazim

Dissertations

Tahrir Square not only represents a symbol of liberation but also reflects the modern history of Egypt. Its several physical changes signify the rise and fall of the monarchy, colonialism, modernism, nationalism, capitalism, echoing a constantly changing definition of the Egyptian public space. And while the surrounding façades physically define the square, either the authorities or the public control its activities.

Khedive Ismail founded the square around 1869 as a roundabout on his “Paris along the Nile” modern city. Between 1882 and 1947, the site became the barracks’ location for the British troops who colonized Egypt. In 1952, an Egyptian …

Temporal Evolution Of Structure And Function In The Periphery And Central Auditory Systems With Mild Blast Induced Tinnitus In Rat Animal Models, Ningning Shao

Dissertations

Exposure to blast causes debilitating trauma including tinnitus among soldiers and civilians (Cave et al., 2007; Remenschneider et al., 2014; Singh et al., 2016). Tinnitus is a constant ringing noise perception without external acoustic event; it affects sleep, concentration, behavior, leading to suicidal tendencies (Swan et al., 2017). Though blast induced tinnitus has been studied, structural and functional dysfunctions along auditory systems have not been systematically studied. It was hypothesized in this work that blast causes tinnitus even while the ears are mechanically protected, and the damage occurred in both central and peripheral auditory systems, which contributed to increased anxiety …

Using Visual Storytelling To Design Solutions-Based Approaches To Homelessness, Peggy Peattie

Dissertations

Despite millions of dollars spent over several decades on assistance programs, the nation’s homeless population has increased for the last four years in a row. The number of people reporting as homeless for the first time doubled in San Diego between June 2019 and June 2020. Trying to impose a one-size-fits-all model of care on a population comprised of unique individuals has resulted in many homeless opting for the street rather than subjugating themselves to rules they feel do not treat them with respect and dignity. Yet, the perspectives of homeless individuals are excluded from decision-making dialogue around policies and …
