Worldwide, there are currently more than 50 million people living with dementia and this number is projected to exceed 135 million by 2050. Unfortunately, negative stereotypes and misconceptions about dementia continue to exist, which can result in harm, isolation, and stigma towards those living with dementia. Dementia Friends is an anti-stigma and educational campaign that trains volunteers called “champions” to host informational sessions out in the community. During these sessions, champions educate local community members about the impact of dementia and what they can do to help. These community members are known as a “dementia friend” and are encouraged to help those with dementia live welll. Although Washington state is the fourteenth state to adopt the Dementia Friends program from the United Kingdom, limited research is available about the effectiveness of the program. This study seeks to evaluate the effectiveness of the Dementia Friends program in training the champions in Seattle and Yakima by comparing pre-training and post-training questionnaires. Results from this study will guide the expansion of the Dementia Friends program in other cities. Online questionnaires were distributed to 15 champions before and after the training session via RedCap. In order to assess the champions’ attitudes, perceptions, and experiences about dementia, participants were given 20 subjective statements about dementia and a 7-point Likert scale to assess the degree to which participants agree or disagree with each statement. We anticipate that Dementia Friends will be effective in educating community members and reducing misconceptions regarding dementia. If efficacious, we recommend Dementia Friends to be adopted across Washington to de-stigmatize dementia by educating community members.

Plants take up silica over the course of their lives along with other essential nutrients in the water that they absorb through their roots. The silica becomes deposited within their tissues in the form of solid bodies (phytoliths); when the plant dies and decays, phytoliths are left in the soil where they can fossilize. Fossil phytoliths preserve the original morphology of plant cells and can be used to reconstruct past vegetation. The Middle Miocene Climatic Optimum (MMCO) was a major global warming event that happened ~17-14.5 million years ago. Researcher have reconstructed the climate of the Santa Cruz Formation in Patagonia, Argentina during this period as warmer and drier. While we would expect the vegetation to become more open (i.e., grassy or shrubby versus forested), phytoliths from the Santa Cruz Formation tell a different story; in particular grass phytoliths (and therefore grass abundance) seem to decrease through time, but also become smaller. Some researchers have noticed that grasses tend to respond to reduced water availability with reduced cell size. Therefore, we hypothesize that the reduced size of grass phytoliths observed in the Santa Cruz Formation during the MMCO is due to increasing aridity. However, because this trend of decreasing cell size was only noticed by qualitative observation, we need to quantitatively assess significant changes in cell size. To do so, I studied and imaged grass phytoliths under a microscope, categorized them by subfamily/tribe based on their shape, and measured their size. I then statistically compared the phytoliths from younger and older strata to test whether there was a change in size through time. This work will be used to predict how our current global warming event may impact plant life based on the trends of the past.

Scholarship on American Buddhism has, from its beginnings, struggled with defining “who” and “what” makes an American Buddhist. American Buddhism has thus been split off into two branches: one “ethnic,” which is defined as being practiced by Buddhist immigrants and their descendants, the other “convert,” which makes up Americans of all races and ethnicities who decide to convert to Buddhism. However, temples like the Tacoma Buddhist Temple, a Jodo Shinshu temple located in downtown Tacoma, is one of these many communities with varied membership that falls outside of the two-branch model and is thus why scholars have disputed the model for its inability to fully describe American Buddhists. The dualism of these the two terms create a divide within the American Buddhist community and also racializes the two categories since the term “ethnic Buddhist” is highly associated with the Asian community. As a result, the two terms fail to recognize many of those who fall outside the model, such as non-Asian Buddhists whose parents were convert Buddhists themselves and Asian Buddhists who grew up in a non-Buddhist household and chose to convert to Buddhism later on in their lives. The terms also have a tendency to polarize communities, making it seem as if “ethnic” communities and “convert” communities and thus “ethnic” and “convert” Buddhists have little interaction. The Tacoma Buddhist temple, however, is a community of not only “ethnic” and “convert” Buddhists practicing Buddhism side by side, but also those who the model fails to recognize. Therefore, through the research gathered at the Tacoma Buddhist Temple, it becomes evident that the two-branch model fails to capture the diversity of American Buddhism.

Methylmercury (MeHg) is a bioaccumulative neurotoxin, dangerous to human health even at trace levels. In inundated soils, MeHg is formed from inorganic mercury by mercury-methylating microorganisms; a process termed methylation. Demethylation, by contrast, converts MeHg into less-dangerous inorganic mercury, and also occurs via microbial activity throughout the aquatic soil profile. Rice grains can be contaminated with MeHg when grown in soils where methylation rates are high; human exposure to MeHg is thus a serious public health concern in places where rice cultivation, high rates of consumption, and soil mercury (Hg) contamination overlap. Our research aims to better understand the soil conditions that favor demethylation over methylation – this information can then be used to reduce rice grain contamination through agricultural practices or rice breeding programs. Specifically, our research focuses on the role of oxygenation and carbon root exudates on the net MeHg accumulation throughout the soil profile. Rice plants grow in flooded, oxygen-free (anoxic) soils, but their roots can leak oxygen (making the rice rhizosphere oxygenated in varying degrees), as well as carbon root exudates. Our project simulated both fully oxic and transiently-oxic (transition) zones, with two different levels of root exudates; we use isotopic tracers to assess respective methylation and demethylation rates in all four treatments in both the vegetated (rhizosphere) and non-vegetated (bulk) soil. Carbon root exudates have been collected from hydroponically-grown rice variety M-206, and can be applied to different soil zones via tubules. Oxygenation of the soil can be measured with mm-scale optode imagery, which allows delicate testing of various oxygen-introduction designs. My role in this interdisciplinary project has been to develop, scale-up, automate, and verify the accuracy and dependability of root-oxygenation and root-exudate introduction systems to be used in upcoming experiments.

Students who speak English as a foreign language (EFLs) are pushed within U.S. academic settings to strive for “standard” English—an academic English heralding grammar “correctness” and adherence to rules. EFL curriculum prioritizes for “standard” English, but ignores the ways that terms like “standard” are exclusive, and rarely addresses how an EFL writer may use language in more inventive ways. How do we re-imagine the teaching of writing in ways that can not only help EFL writers in formal high-stakes writing, but also open the door to other creative uses of writing which need not adhere to such strict and increasingly hackneyed standards? My research will draw from many of the conversations focused on second-language acquisition and bilingual education, including work from scholars such as David Freeman and Sara Alvarez, to understand the most recent and effective approaches to teaching English as a second language, as well as discover what approaches to teaching creative writing hold untapped potential for EFL students to acquire new language skills. I will use The Chicago Manual of Style as a contemporary example of a style guide which prescribes “standard” grammar convention. Using an assortment of the grammar topics selected from Chicago for comparison, I will discuss examples of deviations from grammar conventions by writers from various linguistic backgrounds, including Safiya Sinclair, Ocean Vuong, and Mohsin Hamid. By investigating who makes English “standards,” how EFLs best learn, and how these standards have been broken for the better, I aim to create a subversive style guide for EFL writers which is useful for both formal and creative writing.

Grasslands cover approximately 20% of Earth’s land today and spread gradually worldwide in subtropical areas during the last 40 million years. Pollen data from sedimentary rocks in Myanmar suggest that grasslands might have existed there as early as 25 million years ago but did not spread to other Asian regions until much later, 10-6 million years ago. To fully understand the ecology of these early Asian grasslands, I reconstructed the paleoenvironments of Myanmar during the late Oligocene and early Miocene, 25 to 18 million years ago. I used two paleoenvironmental proxies on paleosol samples from Burmese sedimentary rocks: carbon isotopic composition of bulk sediment and phytolith analysis. The bulk carbon isotopic composition in paleosol is an indirect insight into the local aridity and can help reconstructing soil productivity; phytoliths–silica bodies deposited inside living plant tissue that remain in the soil after the tissue decays, forming fossils—when extracted, can help identify the grass types and their relative abundance in the ecosystem. Documenting the characteristics and paleoenvironmental setting of these early grasslands will help us understanding why they did not spread until millions of years later in Asia –and if this timing of ecological expansion is linked to the regional evolution of monsoonal intensity.

How can we improve healthcare in under-served South East Asian Countries? One possibility is via mobile-health technology. Mobile-health or m-health is the practice of medical and public health supported by mobile and wireless devices. This literature review looks at over 20 years of the emergence of m-health and the prediction of future possibilities. The goal is to look at areas of improvement such as cost efficiency, adapting to the specific country’s infrastructure and integration of m-health in healthcare. In countries like Nepal, m-health has helped to eradicate diseases like malaria, improve neonatal health care and empower female health volunteers. It has also helped gather information such as statistics on usage and distribution of drugs, healthcare workers' interactions with patients and disease surveillance. With the rise of mobile users, healthcare facilities can create a structured international framework to regulate and increase the efficiency of m-health. This research will help facilitate conversations about the potential of m-health and where it needs to be improved so that it can play a pivotal role in healthcare of South East Asian countries.

Indoleacetic acid(IAA) is a common and well understood auxin class phytohormone that promotes plant growth by increasing cell division and elongation. IAA has also been shown to increase infectious adhesion and filamentation in certain strains of Saccharomyces cerevisiae. Increased IAA production by the plant’s microbiome has been demonstrated to stimulate host and symbiont growth. The IAA production in multiple strains of S. cerevisiae from the USDA ARS library was quantified using the Salkowski colorimetric technique, then the highest IAA producing strains were treated onto corn to examine the effect on biomass growth. Preliminary results have shown greatly increased root mass and moderately increased shoot mass in treated corn. This symbiotic yeast treatment could have agricultural applications, increasing crop yields without increased application of fertilizer, pesticides, or other products that could have a negative ecologial impact or detrimental effects on the crop.

Solar steam generation has received considerable attention as one of the most promising solar energy harvesting technologies for applications in water desalination, sterilization, distillation, and power generation. Recent research suggests that plasmonic metal nanocrystals can be used as efficient light-to-heat transducers in solar-to-steam applications due to their strong localized surface plasmon resonances; however, large-scale implementation of solar stream generation based on plasmonic metal nanostructures is restricted due to their high cost, structural stability, and low recycling rates. I propose to develop earth-abundant copper iron sulfide nanocrystals as alternative photothermal transducers and apply them in solar steam generation. These nanocrystals can be engineered for efficient light-to-heat conversion and strong, broadband solar absorption. Moreover, they not only consist of earth abundant elements but also have high recycling rates. I plan to work towards enabling large-scale solar stream generation for the sustainable development of our society.
