Austronesian Maritime Migrations: Past And Present - A.B. Lapian Memorial Lecture 2024, James J. Fox

Antropologi Indonesia

This lecture is given in honour of A.B. Lapian whom I had the good fortunate to know. He was a notable scholar whose knowledge of the maritime world of Nusantara was exemplary. As an historian, he had a clear understanding of the broad contours of regional maritime history but equally, he had a concern for the illuminating details of that history. He had a special interest in the Bajau as a maritime population and in their crucial historical role in the trepang trade. I was fortunate to have participated in the International Seminar Professor Lapian organized on the Bajau in …

Participants: There were no participants in this study. Results: More than half of the videos portrayed 'body checking', a potentially harmful practice for body image. Of the videos that represented body …

Enabling Secure And Inclusive Education For Students With Disabilities And Ensuring Data Through Machine Learning, Bader Muteb Alsulami, Abdullah Baihan, Ahed Abugabah

All Works

The COVID-19 pandemic precipitated an abrupt transition to online learning, impacting students with disabilities uniquely. This study examines the experiences of 62 such students in the new educational paradigm, employing a mixed-methods approach. Quantitative data were collected through surveys and questionnaires to assess privacy and security concerns arising from online learning tools. Qualitative insights were gathered via interviews and focus groups, revealing that while students appreciate the flexibility of online learning, they express a critical need for enhanced guidance and support. Neurodiverse students, in particular, emphasized the necessity of a secure online environment. Addressing these challenges, our research integrates blockchain …

Historical Redlining, Contemporary Gentrification, And Severe Maternal Morbidity In California, 2005-2018, Xing Gao, Rachel Morello-Frosch, Amani M. Nuru-Jeter, Jonathan M. Snowden, Suzan L. Carmichael, Mahasin S. Mujahid

OHSU-PSU School of Public Health Faculty Publications and Presentations

Importance Historically redlined neighborhoods may experience disinvestment, influencing their likelihood of gentrification, a process of neighborhood (re-)development that unequally distributes harms and benefits by race and class. Understanding the combined outcomes of redlining and gentrification informs how the mutually constitutive systems of structural racism and racial capitalism affect pregnancy outcomes. Objective To examine if historical redlining and contemporary gentrification is associated with increased severe maternal morbidity (SMM) odds. Design, Setting, and Participants This cross-sectional study used data from a statewide population-based sample of all live hospital births at 20 weeks’ gestation or more between 2005 and 2018 in California. Analysis …

Duncan NRI Faculty and Staff Publications

Arousal and motivation interact to profoundly influence behavior. For example, experience tells us that we have some capacity to control our arousal when appropriately motivated, such as staying awake while driving a motor vehicle. However, little is known about how arousal and motivation jointly influence decision computations, including if and how animals, such as rodents, adapt their arousal state to their needs. Here, we developed and show results from an auditory, feature-based, sustained-attention task with intermittently shifting task utility. We use pupil size to estimate arousal across a wide range of states and apply tailored signal detection theoretic, hazard function …

Melanism In Polymorphic Terrestrial Snakes: A Meta-Analysis And Systematic Review, Ryan A. Martin

Faculty Scholarship

Background and Aim: Colour polymorphic populations constitute excellent model systems for testing ecological and evolutionary hypotheses, as alternate colourations are associated with differences in various biological, behavioural and life-history traits. Melanism is the most common and most obvious form of polymorphism. In reptiles in general (and snakes in particular), thermal melanism has been a popular hypothesis used to explain the appearance of black individuals. It suggests that a trade-off exists between superior thermoregulation and reduced protection through the loss of crypsis. Surprisingly, despite the growing body of literature available, to date, there are only two qualitative reviews on the evolutionary …

Community-Led Climate Preparedness And Resilience In Boston: New Evidence From Communities Of Color, Katsyris Rivera-Kientz, Rosalyn Negron, Lorena Estrada-Martínez, Nyingilanyeofori Hannah Brown, Chidimma Ozor Commer, Mahesh Admankar, Jessica Lillquist, Nicholas Johnson, Racheal Inegbedion, Paul Watanabe

Sustainable Solutions Lab

Communities of color have been historically excluded and marginalized in the ongoing conversations about climate preparedness and resilience at local, national, and global levels. Using focus groups composed of Boston communities of color (Asian American, Black, Latino, and Native American), this study aimed to understand their perspectives on climate change, providing in-depth knowledge of its impact and their views on preparedness and resilience. Research shows that these communities have long been concerned about climate change and emphasize the urgent need to improve climate preparedness. A multi-pronged approach is crucial: listening to communities of color to leverage local knowledge and leadership, …

Comparing The Health Information Practices Of Sapphic People By Age Group And Generation, Vanessa Lynn Kitzie

Faculty Publications

This qualitative research examines how sapphic people (i.e., umbrella term inclusive of lesbian, bisexual, and pansexual trans femmes, mascs, nonbinary people, and ciswomen) in South Carolina navigate informational barriers within healthcare systems. An information practices lens that examines how sapphic people create, seek, use, and share information to achieve desired healthcare outcomes describes such navigation. The research focuses on how intersectional identities, with a particular emphasis on age and considerations of race/ethnicity, geography, and gender, mediate these practices and their outcomes. The research uses participant data from semi-structured interviews and focus groups with 34 sapphic people about their health information …

A Comparison Of Manual And Automatic Force-Onset Identification Methodologies And Their Effect On Force-Time Characteristics In The Isometric Midthigh Pull, Stuart N. Guppy, Claire J. Brady, Yosuke Kotani, Shannon Connolly, Paul Comfort, Jason P. Lake, G. Gregory Haff

Research outputs 2014 to 2021

The aim of this study was to assess the agreement of three different automated methods of identifying force-onset (40 N, 5 SDs, and 3 SDs) with manual identification, during the isometric mid-thigh pull (IMTP). Fourteen resistance-trained participants with > 6 months experience training with the power clean volunteered to take part. After three familiarisation sessions, the participants performed five maximal IMTPs separated by 1 min of rest. Fixed bias was found between 40 N and manual identification for time at force-onset. No proportional bias was present between manual identification and any automated threshold. Fixed bias between manual identification and automated was …

BACKGROUND: We evaluated sociodemographic and clinical predictors of financial toxicity (FT) among patients with breast cancer with higher risk clinical factors warranting regional nodal irradiation (RNI).

METHODS: Among 183 participants in a clinical trial of conventional vs. hypofractionated treatment with RNI, 125 (68 %) completed a pilot survey of FT measured using the validated Economic Strain and Resilience in Cancer (ENRICh) instrument, scored from 0 (minimal) to 10 (severe) FT. Associations with predictors were evaluated using Pearson correlation coefficients and Kruskal Wallis, Mann-Whitney U, and Jonckheere-Terpstra tests. Predictors of severe FT (ENRICh≥5) were tested using multivariable logistic regression with odds …

Artificial Intelligence, Copyright Registration, And The Rule Of Doubt, Thomas B. James

Texas A&M Law Review

Artificial intelligence (“AI”) technology has detonated an explosive burst of seemingly creative expression. Stories, images, music, and even entire books are now being generated very quickly. This development is a major headache for copyright registrars because the copyrightability of works created in this way is uncertain. The almost limitless variability in the extent of human involvement in the creation of a work using an AI tool compounds the uncertainty. In some cases, copyrightability is easy to determine, such as where an author only claims rights in the selection and arrangement of AI-generated output rather than the output itself. But in …

Group Dynamics, Gender, And Field : An Ethnographic Study Of The Yo-Yoing Sport Subculture In Hong Kong, Ho Wang Kwong

Lingnan Theses (MPhil & PhD)

This research explores the yo-yoing sport subculture in Hong Kong, tracing its evolution from a popular pastime to a recognized sport with a global competition structure led by the International Yo-Yo Federation. By situating yo-yoing within lifestyle sports literature, this study offers a sociological understanding of yo-yo players’ experiences and challenges in Hong Kong. Yo-yoing is an interesting case to study because of its prevailing label as a toy hobby, thus players are generally positive to mainstreaming which differs from many lifestyle sports participants’ reluctant attitude. The central question of this study is: How does a subculture gain legitimation as …

Examining Management And Employees' Perceptions Of Occupational Heat Exposure And The Effectiveness Of A Heat Stress Prevention Intervention On Safety And Well-Being Among Natural Gas Construction Workers: A Qualitative Field-Based Study, Muinat Abolore Idris, Christine Markham, Kristina D Mena, William B Perkison
