Context. Mid-infrared emission features are important probes of the properties of ionized gas and hot or warm molecular gas, which are difficult to probe at other wavelengths. The Orion Bar photodissociation region (PDR) is a bright, nearby, and frequently studied target containing large amounts of gas under these conditions. Under the “PDRs4All” Early Release Science Program for JWST, a part of the Orion Bar was observed with MIRI integral field unit (IFU) spectroscopy, and these high-sensitivity IR spectroscopic images of very high angular resolution (0.2′′) provide a rich observational inventory of the mid-infrared (MIR) emission lines, while resolving the H …

Reading Colonial Transitions: Archival Evidence And The Archaeology Of Indigenous Action In Nineteenth-Century California, Lee M. Panich, Gustavo Flores, Michael Wilcox, Monica V. Arellano

Faculty Research, Scholarly, and Creative Activity

Archaeologists in North America and elsewhere are increasingly examining long-term Indigenous presence across multiple colonial systems, despite lingering conceptual and methodological challenges. We examine this issue in California, where archaeologists and others have traditionally overlooked Native persistence in the years between the official closing of the region’s Franciscan missions in the 1830s and the onset of US settler colonialism in the late 1840s. In particular, we advocate for the judicious use of the documentary record to ask new questions of Indigenous life during this short but critical period, when many Native Californians were freed from the missions and sought new …

Enhancing Evacuation Warning Responsiveness: Exploring The Impact Of Social Interactions Through An Agent-Based Model Approach, Alessandro Toledo Salazar, Matthew Medrano, Mathias Duque Medina, Julio Roa, Jorge E. Pesantez

Mineta Transportation Institute

Evacuations are the preferred response to human- or natural-caused disasters. The process often involves people deciding when and how to evacuate based on messages from local authorities. However, diverse opinions of the affected people may influence their decision to evacuate or to stay and see how the situation unfolds. This project applies an opinion dynamics concept to model the opinion and decision-making of people threatened by wildfire. To demonstrate how individual opinions evolve with time, the model applies an agent-based approach that includes the interaction between an agency sending an evacuation message and the affected population. There are three sources …

Faculty Research, Scholarly, and Creative Activity

Experimental evolution studies, in which biological populations are evolved in a specific environment over time, can address questions about the nature of spontaneous mutations, responses to selection, and the origins and maintenance of novel traits. Here, we review more than 30 years of experimental evolution studies using the bacteriophage (phage) Φ6 cystovirus. Similar to many lab-studied bacteriophages, Φ6 has a high mutation rate, large population size, fast generation time, and can be genetically engineered or cryogenically frozen, which facilitates its rapid evolution in the laboratory and the subsequent characterization of the effects of its mutations. Moreover, its segmented RNA genome, …

Intra- And Interannual Variation In The Foraging Behavior Of Common Murres (Uria Aalge) In The Central California Current, Sean Gee, Pete Warzybok, Michael E. Johns, Jaime Jahncke, Scott A. Shaffer

Faculty Research, Scholarly, and Creative Activity

Seabirds modify their behavior during the breeding season as they transition from incubation (self-feeding) to chick-rearing (self-feeding + chick provisioning) periods, which affects parental foraging patterns and distribution. However, it is less clear how much flexibility parents have to modulate their behavior when environmental conditions are unusually poor. Using GPS loggers and time depth recorders, we examined the foraging flexibility of common murres (Uria aalge) at Southeast Farallon Island as adjustments were made between breeding phases and across consecutive years (2019 and 2020) with contrasting oceanographic conditions (i.e. prominent marine heatwave in 2019). Foraging trips were longer during the incubation …

Romanowsky, Jean P. Brodie, Lydia Haacke, Anna Ferré-Mateu, Shany Danieli, Pieter Van Dokkum, Maria Luisa Buzzo, Warrick J. Couch, Zili Shen

Faculty Research, Scholarly, and Creative Activity

We present spatially resolved Keck Cosmic Web Imager stellar spectroscopy of the Virgo cluster dwarf galaxies VCC 9 and VCC 1448. These galaxies have similar stellar masses and large half-light radii but very different globular cluster (GC) system richness (∼25 versus ∼99 GCs). Using the KCWI data, we spectroscopically confirm 10 GCs associated with VCC 1448 and one GC associated with VCC 9. We make two measurements of dynamical mass for VCC 1448 based on the stellar and GC velocities, respectively. VCC 1448’s mass measurements suggest that it resides in a halo in better agreement with the expectation of the …

A Catalogue And Analysis Of Ultra-Diffuse Galaxy Spectroscopic Properties, Jonah S. Gannon, Anna Ferrcrossed D Sign©-Mateu, Duncan A. Forbes, Jean P. Brodie, Maria Luisa Buzzo, Aaron J. Romanowsky

Faculty Research, Scholarly, and Creative Activity

In order to facilitate the future study of ultra-diffuse galaxies (UDGs), we compile a catalogue of their spectroscopic properties. Using it, we investigate some of the biases inherent in the current UDG sample that have been targeted for spectroscopy. In comparison to a larger sample of UDGs studied via their spectral energy distributions (SED), current spectroscopic targets are intrinsically brighter, have higher stellar mass, are larger, more globular cluster-rich, older, and have a wider spread in their metallicities. In particular, many spectroscopically studied UDGs have a significant fraction of their stellar mass contained within their globular cluster (GC) system. We …

Cyber Loafing And Innovative Work Behavior As Predictors Of Perceived Job Performance: A Nigerian Study, Oluyomi Folorunso, Ruth Okeile
