Is Active Voice Enough? Community Discussions On Passive Voice, Mmiwg2s, And Violence Against Urban Indigenous Women In San José, California, Soma De Bourbon, Ketzal Gomez, Beatriz San Juan

Faculty Research, Scholarly, and Creative Activity

Men commit violence against Native American women at higher rates than other racial or ethnic groups. When violence against Indigenous women is discussed and written about, it is often in passive voice. Several scholars note the problem of using passive voice to talk about violence against women, but there is little research on how women themselves understand passive voice as connected to the violence perpetrated against them, and we found no literature on how Native women understand passive voice. This research asks how urban Native and Indigenous women understand passive language in relationship to violence. The authors, who are all …

Early Starts And Late Finishes Both Reduce Alertness And Performance Among Short-Haul Airline Pilots, Lucia Arsintescu, Sean Pradhan, Ravi G. Chachad, Kevin B. Gregory, Jeffrey B. Mulligan, Erin E. Flynn-Evans

Faculty Research, Scholarly, and Creative Activity

Flight crews are frequently required to work irregular schedules and, as a result, can experience sleep deficiency and fatigue. This study was conducted to determine whether perceived fatigue levels and objective performance varied by time of day, time awake, and prior night's sleep duration. Ninety-five pilots (86 male, 9 female) aged 33 years (±8) volunteered for the study. Participants completed a daily sleep diary, Samn-Perelli fatigue scale, and psychomotor vigilance task that were completed before and after each flight duty period and at the top-of-descent for each flight. Pilots experienced higher self-reported fatigue (EMM = 3.92, SE = 0.09, p < 0.001) and worse performance (Response speed: EMM = 4.27, SE = 0.08, p = 0.004) for late-finishing duties compared with early-starting duties (Samn-Perelli: EMM = 3.74, SE = 0.08; Response speed: EMM = 4.37, SE = 0.08), but had shorter sleep before early-starting duties (early: EMM = 6.94, SE = 0.10; late: EMM = 8.47, SE = 0.14, p < 0.001). However, pre-duty Samn-Perelli and response speed were worse (z = 4.18, p < 0.001; z = 3.05, p = 0.03; respectively) for early starts compared with late finishes (EMM = 2.74, SE = 0.19), while post-duty Samn-Perelli was worse for late finishes (EMM = 4.74, SE = 0.19) compared with early starts (EMM = 4.05, SE = 0.12). The results confirm that duty time has a strong influence on self-reported fatigue and performance. Thus, all flights that encroach on a biological night are targets for fatigue risk management oversight.

Meta-Algorithms In Machine Learning, Vishnu Pendyala

Open Educational Resources

This presentation explores how to make the best of models impacted by bias and variance. Meta-learning minimizes loss. Ensemble methods, including Bagging, Adaboost, Random Forest, Gradient Boosting, and Stacking, are discussed. These methods perturb data (X or Y) using techniques like bootstrap sampling, k-fold sampling, weighted sampling, and random subspaces. Models are generated in parallel or sequentially, with aggregation strategies such as mean, mode, weighted response, and metamodel. The presentation also touches upon deep learning and one-shot learning, and explains how distances become less meaningful in high dimensions.

Association Between Stone Fruit Intake And Markers Of Cardiovascular Disease Risk Among United States Adults: Nhanes 2017-2018, Lasya S. Shah

Master's Theses

Cardiovascular Disease (CVD) is the most common cause of mortality in the world affecting people from all backgrounds. There is abundant evidence supporting diet affecting the risk for CVD. The consumption of fruits and vegetables is inversely related to CVD risk factors, likely due to their content of phenolic compounds. Although stone fruits contain high quantities of phenolic compounds, it remains unclear if their intake is associated with CVD risk. In this study, data from the National Health and Nutrition Examination Survey 2017-2018 were used to estimate the consumption level of stone fruits and whether it was associated with CVD …

Coherent Interactions Between Silicon-Vacancy Centers In Diamond, Matthew W. Day, Kelsey M. Bates, Christopher L. Smallwood, Rachel C. Owen, Tim Schröder, Edward Bielejec, Ronald Ulbricht, Steven T. Cundiff

Faculty Research, Scholarly, and Creative Activity

We report tunable excitation-induced dipole-dipole interactions between silicon-vacancy color centers in diamond at cryogenic temperatures. These interactions couple centers into collective states, and excitation-induced shifts tag the excitation level of these collective states against the background of excited single centers. By characterizing the phase and amplitude of the spectrally resolved interaction-induced signal, we observe oscillations in the interaction strength and population state of the collective states as a function of excitation pulse area. Our results demonstrate that excitation-induced dipole-dipole interactions between color centers provide a route to manipulating collective intercenter states in the context of a congested, inhomogeneous ensemble.
