Migration, Remittances, And Child Growth: Evidence From Cambodia, Vatana Chea, Patcharawalai Wongboonsin

Journal of Demography

Remittances have become a main resource for development in low- and middle-income countries around the world. With impressive growth in remittances over the decades comes interest in their importance to development. Using data from the 2009 Cambodian Socio-Economic Survey with a sample of 2,767 children under 5 years of age, this study investigates the impact of migration and of remittances on children's quality of health, and tests whether or not the so-called permanent income hypothesis holds for remittances relative to other income. Also employed is two-stage least squares analysis to account for potential endogeneity problems. In short, it was found …

Effects Of Ball Milling Duration And Sintering Temperature On Mechanical Alloying Fe3si, Varistha Chobpattana, Chakansin Phoomkong, Peerawat Nutnual, Kritsada Thaengthong, Wanchai Pijitrojana

Journal of Metals, Materials and Minerals

Fe3Si is under interest as a ferromagnetic electrode of magnetic tunneling junctions (MTJs). Its crystalline structure is important for achieving high device efficiency. This work focuses on mechanical alloying of 3:1 ratio of 99% pure Fe and Si powder mixtures by ball milling and sintering. The mixtures were ball-milled for various durations up to 20 h. Then, they were sintered from 400°C  to 800°C for 4 h in Ar.  SEM images and particle size analysis show significant reduction in average particle size of the mixtures after ball milling for 20 h. The longer duration of ball milling process promotes powder …

(R2165) Two Different Stages With Two Distinct Harvesting Processes, S. Vijaya, Krishika M

Applications and Applied Mathematics: An International Journal (AAM)

This study extends the classical Lotka-Volterra prey-predator model by incorporating a stage structured prey population consisting of juvenile and adult stages, while considering a single predator species governed by a Holling type II functional response. The growth of the juvenile prey depends on the adult prey population and since the juvenile prey has no reproduction capability. Two distinct harvesting strategies are introduced in the model. Constant-yield harvesting is applied to the juvenile stage of the prey population and represents a fixed amount of harvest regardless of population size. Constant effort harvesting is applied to the adult stage of the prey …

White, Heterosexual, Cisgender Male Experiences With Contemporary Masculinity Language, Marcus D. Kako

Doctoral Dissertations

Studies suggest that rigid adherence to tenets of traditional masculinity (e.g., dominance, restrictive emotionality, aggression) can lead to adverse physical and mental health outcomes in men and marginalized groups (e.g., Burke, 2002; Jampel et al., 2020; Jewkes et al., 2011; Mesler et al., 2022). However, literature demonstrates that many men have an aversion to changing thoughts, values, and behaviors related to traditional masculinity, and that the language used to discuss these changes affects men’s willingness to engage in adopting new perspectives and values (e.g., Smedley & Croffie, 2023; Stein, 2018). Thus, this dissertation focuses on understanding how White, heterosexual, cisgender …

Associations Between Sexual And Gender Minority Stress Exposure And Schizophrenia-Like Experiences In The South, Lillian A. Hammer

Dissertations

Background: Negative experiences related to one’s minority identity serve as stressors contributing to mental health concerns for those identifying as a sexual and/or gender minority (SGM). SGM groups have greater severity of some mental health symptoms than non-SGM individuals, yet it is poorly understood whether these findings extend to schizophrenia-like experiences (SLEs). SLEs are associated with significant distress and may indicate risk for the development of schizophrenia-spectrum disorders. Associations between exposure to minority stress and SLEs are underexplored. This study aimed to fill this gap by assessing whether exposure to SGM-related minority stress was related to SLEs using ecological …

The Moderating Role Of Coping Strategies In The Relationship Between Depressive Symptoms And Hypersexuality Among Young Filipino Adults, Kathryn H. Jacob, Voltaire M. Marquez

Makara Human Behavior Studies in Asia

Mental health among young adults is receiving increasing attention because of its significant influence on overall well-being, including physical health, interpersonal relationships, and daily functioning. Among the key concerns within this age group are depression and hypersexuality. This study investigated the moderating role of coping strategies in the relationship between depressive symptoms and hypersexuality. We hypothesize that adaptive coping strategies—such as problem- and emotion-focused coping—would attenuate the negative effects of depressive symptoms on hypersexual behavior, whereas avoidant coping would intensify this relationship. To test these assumptions, a cross-sectional explanatory study was conducted involving 407 Filipino young adults aged 18 to …

Analyzing Environmental Education In Northern Mississippi And Its Impact On Student Outcomes, Vishnu S. Gadepalli

Honors Theses

This thesis examines environmental education in public high schools in northern Mississippi, investigating how educators describe its presence, delivery, and institutional support in communities disproportionately burdened by environmental harm. Seven semi-structured interviews were conducted with high school teachers across four northern Mississippi schools, transcribed verbatim, and analyzed through iterative thematic coding under Institutional Review Board approval. Five themes emerged: opportunistic curricular integration, time and standards as overriding structural constraints, passive institutional support, student receptivity tempered by limited awareness, and significant variation across school contexts with one magnet school as a clear outlier. The study concludes that environmental education in these …

Purification Of Protoporphyrin Ix Using The Fplc, Ken Overway, Laura Narby

Honors Projects

Protoporphyrin IX (PPIX) is the main pigment in brown eggshells, and it is embedded in the shell gland of hens during the final stages of the egg-making process. This natural dye can be used as a substitute for organic sensitizers in dye-sensitized solar cells (DSSCs). One benefit of PPIX is that it is a natural resource and has a high absorption coefficient in the visible and near-infrared region (NIR). Purified PPIX is extremely helpful in dye-sensitized solar cells because it improves electron injection efficiency, can be chemically modified to improve its absorption efficiency, and can be mixed with nanomaterials such …

Avian Influenza And The Approach To Designing An H5n1 Vaccine, Lauren N. Hickey

Honors Program: Senior Projects (Public)

The Avian influenza virus (AIV) H5N1 has been responsible for the culling and deaths of millions of birds since 2022 with concern for wildlife, livestock, and human infections occurring as well. With eggs flying off the shelves in grocery stores, even individuals not involved in the agricultural industry have seen the drastic effects of this disease first-hand. For chickens, this virus works quickly and overpowers the innate immune system before the adaptive immune system has time to properly respond. Therefore, a safe and effective vaccine could reduce the number of poultry deaths and prevent the continuous spread of the infection. …

Neuropsychological Profiles To Aid In Determining The Necessity For Neuroimaging Reviews: Providing Evidence For A Screener For Cerebrovascular Abnormalities, Kayla Blaire Miller

Theses and Dissertations

This study aimed to provide evidence for a white matter abnormality (WMA) screener by investigating whether commonly used neuropsychological measures of executive functioning and processing speed have predictive power for identifying high WMA burden.

Participants were administered a brief neuropsychological evaluation by a doctoral student under the direct supervision of a board-certified clinical neuropsychologist and underwent an MRI scan. A neurologist rated each participant’s MRI results using the Fazekas scale. A total of 178 participants were included, divided into two groups based on their Fazekas rating: low WMA burden (46%) and high WMA burden (54%).

A confirmatory factor analysis indicated …

Childhood Emotional Maltreatment And Its Associations With Internalizing And Externalizing Symptoms In Emerging Adults, Amira C. Wallace

Undergraduate Theses and Capstone Projects

This study examines how childhood emotional maltreatment influences mental health symptoms among college students aged 18 to 25, specifically exploring its association with increased prevalence and severity of depression, anxiety, hyperactivity, and aggression symptoms in emerging adulthood. The relationship between childhood emotional maltreatment and internalizing and/or externalizing mental health symptoms will be assessed using questionnaires. This study aims to provide recommendations for the development of supportive and inclusive academic environments that facilitate informed conversations and interventions regarding childhood maltreatment. Findings could provide valuable information about students with histories of childhood maltreatment to academic institutions, which could in turn be used …

Reflecting On Psychotherapy In Adolescence: A Qualitative Analysis Of Processes Of Change, John Parigger

Electronic Theses and Dissertations

There is a sharp increase in anxiety and depression symptoms in adolescence, and many forms of psychotherapy are shown to be effective. However, most research has examined average effects for manualized treatments that address multiple areas of functioning, which makes it difficult to determine how psychotherapy causes positive change. Process-based therapy postulates that all psychotherapies work through promoting adaptive biopsychosocial patterns of behavior (i.e., processes of change). Research has increasingly focused on the process-based therapy model, and there is a need for qualitative studies to incorporate lived experience into our understanding of change processes. The current study utilized the process-based …

The Effect Of Resilience: Exploring The Link Between Depression And Cognitive Performance In A Memory Disorder Clinic Population, Amanda Capriglione

Theses and Dissertations

Introduction: Research has consistently shown that depressive symptoms are associated with cognitive impairments, namely in memory, attention, and executive functioning (for a review, see Rock et al., 2014), particularly in individuals with mild cognitive impairment (MCI). As MCI is often a precursor to dementia, understanding and addressing modifiable factors that influence this trajectory is essential for prevention and intervention efforts. Resilience, defined as the capacity to adapt positively to adversity, has been identified as a potential protective factor against age-related cognitive decline. Prior studies (e.g., Laird et al., 2019b; Miller et al., 2023) suggest that resilience buffers against the cognitive …

Sanctuary: Counter-Oppressive Relationships With Farmed Animals As An Ecopsychological Imperative, Kelsey Bomboy

The International Journal of Ecopsychology (IJE)

Consumers are intentionally shielded from and often misled about the process of breeding, raising, and slaughtering animals for consumption. By confining most farmed animals to warehouses in rural areas while the majority of humans are sequestered in urban areas, we have effectively created a world where humans do not have to contend with the sense of interconnectedness that arises when witnessing and being witnessed by a farmed animal. Within industrial slaughterhouses, the physical act of killing is minimized to just a fraction of the workers, so that even those who are responsible for rendering a once living being will never …

Impact Of An All-Gender Cabin Intervention At A Residential Summer Camp On Self-Esteem And Perceived Social Support In Lgbtq+ Youth, Suzanne D. Dinubile

Doctoral Dissertations

This study is a program evaluation with a mixed-methods design that evaluated the impact of Camp Tawonga’s All-Gender Cabin Intervention and LGBTQ+ programming showed no statistically significant changes, likely due to small sample size, but descriptive trends indicated improved outcomes for LGBTQ+ youth in All-Gender cabins. Semi-structured interviews with six LGBTQ+ campers revealed increased self-awareness and acceptance, empowerment, self-confidence, and a stronger sense of belonging within the LGBTQ+ community, along with positive interactions with non-LGBTQ+ peers. Notably, the three campers in All-Gender cabins highlighted unique themes of identity affirmation, emotional and behavioral growth, and relief from minority stress. Findings support …

From Uncertainty To Dialogue: Visualising Collaborative Noticing And Mathematical Intuitions In Students' Narratives Within Probability Learning, Daniela Diaz-Rojas

The Mathematics Enthusiast

This study explores the critical role of language and communication in fostering collaborative noticing practices that display mathematical intuitions within probability learning. Through an analysis of student interactions, I show how the joint articulation of ideas and the exploration of shared doubt enable intuition, often perceived as an object that is held and a solitary experience, to become a socially shared and co-constructed process. The observed collaborative dialogue concerns shared content and form, constructing a joint narrative architecture that enables common understanding and allows the group to notice, examine, and reshape their intuitions. Collaborative noticing when working with probability problems …

The Smuggled Body: Embodied Experiences Of Sudanese Displacement Along The Sudan–Egypt Corridor, Marielys Padua Soto

Theses and Dissertations

The outbreak of conflict in Sudan in April 2023 triggered one of the world's largest displacement crises, forcing millions of Sudanese civilians to flee toward neighboring countries, particularly Egypt. As legal pathways became increasingly restricted following Egypt's tightening of visa policies, many asylum seekers relied on migrant smuggling networks to reach safety. This thesis examines how restrictive mobility regimes are materially experienced through the body by introducing the concept of the smuggled body, defined as the body through which the physical, emotional, and social consequences of border control, irregular mobility, and forced displacement are lived. Drawing on embodiment theory, border …

Nanoscale Water Confinement And Coordination-Driven Ion Transport In Eutectogel Electrolytes For Electrochemical Energy Storage Applications, Abdallah Akar

Theses and Dissertations

The rapid expansion of renewable energy systems, portable electronics, electric vehicles, and smart grid technologies has intensified the demand for advanced electrochemical energy storage devices capable of delivering high power density, long cycling life, operational safety, and environmental sustainability. Among these technologies, supercapacitors have attracted considerable attention because of their rapid charge-discharge capability, excellent cycling stability, and high-power performance. However, their relatively low energy density remains a critical limitation that restricts their broader practical application. Since the energy density of supercapacitors scales with the square of the operating voltage, expanding the electrochemical stability window of the electrolyte represents one of …

Simulation-Based Assessment Of Operational And Retrofit Solutions For Effluent Compliance Of A Capacity-Limited Oxidation Ditch Wwtp, Ahmed Sameh Harash

Theses and Dissertations

Oxidation-ditch wastewater treatment plants (WWTPs) across Egypt's Nile Delta are increasingly carrying hydraulic and organic loads beyond what they were designed for. This work can be considered pioneering as this work compared operational and structural retrofit alternatives for such a plant within a single verified simulation framework. The present study fills that gap by building a digital twin of the Qaha WWTP, a dual-train Carrousel oxidation ditch in Qalyubia Governorate, calibrated to a baseline flow of 7,420 m³/day in the SUMO24 platform (a third-generation, open-source wastewater treatment process simulation software) using the SUMO2c biokinetic model (a simplified variant of Activated …
