Food and Machinery

[Objective] To establish a method for authenticity identification of camellia seed oil. [Methods] The fatty acid composition of camellia seed oil and six common vegetable oils are determined by gas chromatography. Principal component analysis (PCA) is employed to explore the distribution patterns of fatty acids among the vegetable oils and to screen for potentially adulterated oils. Partial least squares discriminant analysis (PLS-DA) is applied to establish a model between fatty acid profiles and actual adulterated oils. Finally, multiple stepwise linear regression analysis is used to establish quantitative analysis models for adulteration in camellia seed oil. [Results] Among the six common …

Dynamical Pathways Of Fear And Anger: Testing The Predictive Validity Of The Basic Evaluation Process Framework, Maryana Borri Madeira

Electronic Theses and Dissertations

The present study tested the predictive validity of the Basic Evaluation Process framework by examining whether Fear and Anger emerge as competing emotional attractors during threat appraisal. Using a mouse-tracking paradigm with audio recording, fifty participants reasoned aloud about a self-selected threatening situation while continuously rating their Fear and Anger. Cross-correlation analysis confirmed dynamic dependence between Fear and Anger, although the coupling was positive rather than negative, indicating co-activation rather than mutual suppression. Vector field analysis identified stable attractor structures for all participants, but the distribution of primary attractors across the Fear by Anger state space did not reveal a …

This paper collects relevant research reports at home and abroad, and sorts out the preparation process, chelation mechanism and characteristics, and biological activity of plant-derived metal ion chelating …

A Machine Learning Approach For Water Quality Assessment In The Lower Rio Grande Valley Watershed, Saika Nowshin Nowrin, Chu-Lin Cheng, Jungseok Ho, Jinwoo An, Fatemeh Nazari

Civil Engineering Faculty Publications

Water quality analysis plays an essential role in maintaining the health and sustainability of river ecosystems, especially in semi-arid regions like the Arroyo Colorado Watershed in South Texas. Since the river is a vital source of water supply for local communities, agriculture, and wildlife, it faces significant challenges and pollution from land use changes, climate variation, and agricultural runoff. Continuous monitoring and assessment of water quality parameters and their temporal variability are essential to ensure the drinking water supply and aquatic ecosystem health. However, comprehensive laboratory-based water quality investigations are often constrained by higher costs, logistical complexity, and limited manpower. …

Enhancing Rapid Reef Resilience Through Transplantation Of Thermally Tolerant Corals In OʻAhu, HawaiʻI, Allison M. Klein

Electronic Theses and Dissertations

Coral reefs are increasingly threatened by marine heatwaves, disease outbreaks, and other anthropogenic stressors, leading to widespread declines in coral cover worldwide. As a result, efforts are increasingly focused on identifying thermally tolerant corals for reef restoration. However, it remains unclear whether thermal tolerance is maintained following transplantation and whether thermally tolerant corals perform differently in novel environments. This dissertation examined thermal tolerance, survivorship, symbiont communities, and growth in two dominant Hawaiian reef-building corals, Montipora capitata and Porites compressa, using a reciprocal transplant experiment between Kāneʻohe Bay and Ulupaʻu, Oʻahu. Initial heat-stress assays showed high thermal tolerance in both …

International Student Athletes And The Covid-19 Global Pandemic: Disruption, Uncertainty, And Coping, Isabella M. Franks, Trent A. Petrie, Whitney G. Moore, Carmyn Hayes

Journal of Athlete Development and Experience

COVID-19 and its ripple effects (e.g., social distancing, sport cancellations, quarantining) negatively affected the careers of collegiate student-athletes. The disruption to university systems and collegiate athletics and the stress and uncertainty felt globally likely increased international student-athletes' (ISAs) risk for distress. Yet, ISAs also possessed unique characteristics and were immersed within supportive sport environments, which may have shaped their psychological responses in distinct ways. The COVID-19 pandemic created an opportunity to understand how ISAs, as individuals navigating both athletic and international identities, responded and coped. To date, no study has examined the initial coping experiences of international collegiate athletes, even …

Cognitive Media Literacy In The Digital Age: Structural And Behavioral Dimensions Of Inequality, Elif Pınar Aciyan Şen, Murad Karaduman

Journal of Media Literacy Education Pre-Prints

The expansion of digital technologies has not only transformed media production and consumption but also reshaped the cognitive conditions through which individuals interpret information. Drawing on W. James Potter’s (2004) cognitive model of media literacy, this study explores how cognitive dimensions of media literacy relate to digital inequalities among adults. To operationalize the model, index variables were developed for its four subdimensions, knowledge structures, personal locus, competencies, and skills, using multiple theoretically defined item domains. Based on a stratified face-to-face survey with 400 adults in Antalya, Türkiye, multiple regression analyses reveal that age and education are the strongest predictors of …

Kinship Caregivers Feel More Satisfied With Services And Better Supported With A Kinship Navigator, Berenice R. Rushovich, Kristin Sepulveda Muñoz, Brittany Mihalec-Adkins, Brooke Derrick, Karin Malm

GrandFamilies: The Contemporary Journal of Research, Practice and Policy

Kinship caregivers caring for children often lack access to services and supports they need to stabilize their families. Other kinship navigator programs have been shown to improve child permanency, child safety, child wellbeing, and adult wellbeing. This study evaluated Kinnections, a kinship navigator program provided by Wayfinder Family Services, operating since 2007 in seven counties in Northern California. Using propensity score matching, 116 kinship caregivers receiving Kinnections services were matched with 116 kinship caregivers in neighboring counties with no kinship navigator services available. The matched sample showed strong baseline equivalence on key caregiver, child, and household factors. Findings showed …

Vietnamese Grandparents' Caregiving Experiences For Grandchildren Impacted By Hiv/Aids: An Ethnographic Study, Lesley M. Harris, Nguyen D. Thang, Linh Thuy Nguyen

GrandFamilies: The Contemporary Journal of Research, Practice and Policy

This ethnographic study explores the caregiving experiences of grandparents in northern Vietnam who are raising grandchildren impacted by HIV/AIDS. Specifically, what is the process of skipped-generation caregiving in families affected by HIV/AIDS in Vietnam? Data were collected between 2009 and 2011 through participant observation and in-depth interviews with 26 grandparent caregivers and eight key informants. Informed by the Caregiving Career framework as a sensitizing concept and using constructivist grounded theory analytic strategies, the study identifies four interconnected caregiving phases shaped by cultural expectations, stigma, and intergenerational disruption. Through fieldwork and analysis, we found that grandparents drew from previous and current …

From Strangers To Family: Fostering Resilience Through Social Support In Grandmothers Raising Grandchildren, Nancy Mendoza

GrandFamilies: The Contemporary Journal of Research, Practice and Policy

Grandparents often unexpectedly assume the role of caregiver with little support. Supporting these caregivers is critical for their health and well-being and that of their grandchildren. This study examines how family-like relationships formed during the GC+ intervention, increasing social support and resilience among grandparent caregivers. Four grandmothers, raising a total of five grandsons, participated in a focus group six months post-intervention. Grandmothers were asked to share their opinions and thoughts regarding the intervention. Using the Convoy Model and Resilience Theory, researchers conducted a deductive content analysis of participants’ perspectives on close family-like relationships cultivated during the intervention. Findings suggest close …
