Abstract:

The Washington Assessment of Risk and Needs (WARNS) is widely used in over 100 districts in the State of Washington. School districts and court entities rely on scores from the WARNS to inform conversations with youth and families about adolescent behaviors related to chronic school absences, or truancy. WARNS assesses six domains including peer deviance, aggression and defiance, substance abuse, depression and anxiety, school engagement, and family environment. With Washington having one of the highest rates of truancy in the United States, WARNS plays a critical role in understanding such factors. We present work in three areas to highlight support for the WARNS. First, our research highlights how we account for a students’ contextual environments when examining WARNS items for fairness, ensuring scores carry equal meaning across ethnic groups. Second, we highlight the development of a computerized adaptive test (CAT) that provides users with a time-efficient and short form of the WARNS, reducing assessment fatigue without degrading score accuracy. Third, we highlight the WARNS models of use from large to small districts around the State, and new developments including a Spanish version. The evidence and use of the WARNS help to bring student voices back into the truancy conversation in the State. Our work has resulted in increased use of the WARNS and decreases in student truancy and negative behavioral trajectories, and have led to distal outcomes of student success.

Abstract:

Color is involved in every aspect of our daily lives, from clothing to food, as a way to visually communicate messages and meanings to others. The purpose of this research was to examine how western society women in the 21st century is using the color “black” to communicate meaning(s) in their fashion. Symbolic Interaction Theory explains that the meanings of clothing are visually perceived by not only the wearers, but others as well. Therefore, the research question was “What are the meaning(s) of the color “black” in the 21st century?”

To address the question, a visual content analysis was conducted with Vogue Magazine from the years 2000-2018 with the three most prominent fashion month issues: March, July, and September. The content analysis confirmed four meanings of “black” color in fashion found in the literature reviews: sophistication, sadness, chic, deviation, and fetish wear. During the content analysis the researchers found an additional two meanings that were not established in the literature review; active wear and work wear. The researchers believe these to be new meanings being established in 21st century fashion, that were unable to be examined in the literature. In conclusion, chic and sophistication are the predominant meanings that are being portrayed by women in mainstream fashion to visually communicate meaning in their dress, when wearing the color black.

The results of this study can help to identify how mainstream fashion is utilizing black as a means of visual communication for contemporary women.

Abstract:

Cancer is the second leading cause of death in the United States and worldwide. Traditional cancer treatments such as chemotherapy, radiation, and surgery are designed to destroy cancer cells but often attack healthy tissue in the process. In immunotherapy, immune cells such as cytotoxic T lymphocytes (CTLs) are extracted, modified, expanded in a bioreactor, and transferred into a patient—this is known as adoptive cell therapy (ACT). There is a need for ACT-based treatments that are widely accessible, scalable, and relatively inexpensive. To address this need, our lab recently developed a high-density, lab-scale centrifugal bioreactor (CBR) which can rapidly expand infected CD8+ T cells from a bovine model. In this study, we aimed to optimize CTL growth by determining kinetic growth parameters based on the levels of glucose and inhibitory metabolites in the culture. It is hypothesized that if we can develop a reliable kinetic growth model, then it will be possible to predict optimal CTL expansion parameters for the bioreactor. Early kinetic studies were performed last fall in which six different glucose concentrations were tested, giving a maximum specific growth rate of 0.0112 1/h and a Monod constant of 2.12 mg glucose/dL. The experiments were repeated recently with different glucose concentrations and the results from those studies will be presented. The optimization of this bioreactor will have a major impact on the availability and efficiency of patient-specific immunotherapy.

Abstract:

Lithium-sulfur battery (Li-S) has been intensively studied in the past years due to its high theoretical energy density and economic benefit. However, there are still several obstacles that greatly limit its practical application such as low conductivity, large volume change and polysulfides shuttling. It is widely reported that nano materials can solve these problems and significantly improve batteries’ performance. Despite the efforts, many of the results are derived from an ideal condition, that is, a low sulfur loading ( 10 µL/mgs). The insufficient active materials as well as the large amount of electrolyte not only results in a low practical energy density but also glosses over some challenges in Li-S batteries. Hence, a high sulfur loading cathode (>4 mg/cm2) and a lean electrolyte condition (= 4 µL/mgs) should be determined in order to deliver repeatable results and reliable conclusions. In this poster, we demonstrate various strategies to achieve high energy density Li-S battery and elucidate the new challenges in this field. Moreover, by investigating the distinct phenomenon under flooded and lean electrolyte condition, we develop a reasonable test protocol and propel Li-S battery research to a practical level.

Abstract:

In modern optical systems, freeform optical components are used to modify the focal length or to correct the wavefront. For instance, wavefront control and correction has been always a critical issue in adaptive astronomical telescopes. Freeform lenses are optical correctors which are widely used to improve the optical performance through the aberration correction. Traditional optical manufacturing techniques such as machining, molding and casting processes demand sophisticated and expensive equipment. Here we introduced magnetism and interfacial force into Additive Manufacturing to develop tunable magnetic liquid molds for rapid, low-cost and straightforward fabrication of freeform lenses. Using customized extrusion-based 3D printers, a magnetic ink was printed either within an immiscible optical elastomeric environment such as polydimethylsiloxane (PDMS) or on a cured elastomeric substrate. The profile shapes at the liquid-fluid interface were regulated using an external adjustable magnetic field. Depending on the field configuration, various freeform optical surfaces can be generated during printing process that served as tunable liquid molds to shape the surrounding optical elastomer into a concave aspherical lens after curing. An apparatus was assembled to provide different magnetic force and to control the gradient of applied magnetic field on the droplets. A home-built Shack-Hartmann sensor was employed to measure the focal length of the formed lenses and the lens profiles were extracted using an axisymmetric drop shape analysis (ADSA). The effects of magnetic field intensity, gradient of magnetic field, and magnetic susceptibility were investigated. This technique can be used for forming lenses with different sizes, shapes and magnifications.

Abstract:

Anaplasma phagocytophilum (Ap) is a tick-transmitted obligate intracellular zoonotic pathogen. Ap achieves intracellular infection by delivering effector proteins into the host cytosol utilizing a Type IV secretion system (T4SS). In contrast to other intracellular pathogens e.g. Legionella pneumophilia and Coxiella burnetii, where 100s of T4SS effectors have been found, only 4 have been identified in Ap. Our goal was to extend the repertoire of known Ap effectors. To predict effectors, we used the recently published T4SS effector prediction software OPT4e to identify Ap proteins containing features characteristic of T4SS substrates. To screen for T4SS translocation, effector candidates were fused to a reporter enzyme, which if translocated to the host cell cytoplasm generates a product detectable by ELISA. To overcome the genetic intractability of Ap, fusion constructs were assayed for translocation by the heterologous T4SS of Legionella pneumophila. Although only 7 of 70 screened proteins were translocated in a T4SS dependent manner, there are likely more effectors since a negative result may be due to the heterologous nature of the reporter system. Three of the translocated substrates localize to the host cell nucleus when ectopically expressed. Bioinformatic analysis identified putative C-terminal nuclear localization signals (NLS) in all three of these T4SS substrates. Deletion of these NLS sequences abrogated both nuclear-specific localization and also T4SS translocation, which is consistent with the requirement for specific C-terminal features in translocation of known effectors. Functional characterization of these and other effectors will inform their role in Ap replication, pathogenesis, and transmission.

Abstract:

Inter-individual differences in the amount of deep sleep, stage N3, in nighttime sleep have been found to be large and trait-like, even during recovery sleep after sleep deprivation. We investigated whether this phenomenon extends to daytime sleep, and whether it is robust to prior caffeine intake.

In an 18-day in-laboratory study, 12 healthy adults underwent three 48-hour periods of total sleep deprivation. In randomized, counterbalanced, double-blind fashion, participants received either placebo, 200 mg caffeine, or 300 mg caffeine every 12 hours during sleep deprivation. Each sleep deprivation period was preceded by three baseline sleep periods (21:00-07:00) and followed by a daytime recovery nap (07:00-12:00). Sleep periods were recorded polysomnographically. Analyses focused on the baseline night immediately preceding and the daytime recovery nap immediately following each sleep deprivation period.

Daytime recovery naps had 44.6±5.1 minutes (mean±SE) more stage N3 sleep than baseline sleep periods (p<0.001). Daytime naps preceded by 200 or 300 mg caffeine intake every 12 hours during sleep deprivation had 15.4±6.2 and 21.6±6.2 minutes less stage N3 sleep, respectively, than daytime naps in the placebo condition (p=0.003). Across the baseline nights and daytime naps, regardless of caffeine condition, there were large inter-individual differences in stage N3 sleep, with a standard deviation over individuals of 23.2 minutes and considerable stability (intraclass correlation coefficient: 0.70). Thus, the amount of deep sleep is a trait characteristic that is robust to sleep deprivation, time of day, and caffeine.

Abstract:

Tumor necrosis factor (TNF) plays a role in regulating sleep. Neuronal activity enhances TNF expression. Co-cultured neuron/glia cells exhibit deeper sleep-like states after TNF administration. Both TNF and TNF receptors (R) are produced as transmembrane ™ proteins that, when cleaved, produce soluble (s) forms. Unlike conventional cell signaling induced by soluble (s) ligands binding to tm receptors, with immunocytes, sTNFR can bind tmTNF and reverse signal within the cell expressing tmTNF. Having previously shown sTNFR sleep inhibition in animals, we hypothesized that tmTNF-sTNFR binding would induce wake-like states in cells through reverse signaling.
Somatosensory cortical neurons/glia from wildtype (WT) mice and mice lacking either TNF (TNF-KO) or both TNFRs (TNFR-KO), were co-cultured and incubated on multi-electrode arrays. Daily one-hour electrophysiological recordings were taken on days 4 – 13 for development analyses. On day 14, a one-hour baseline was recorded prior to sTNFR treatment. Immediately post-treatment, recordings resumed for another hour. Synchronization of electrical activity (SYN), action potentials, slow wave power (SWP), and burstiness index (whole animal sleep defining measures) were used to characterize the emergence of these electrophysiological properties and sTNFR-induced changes.
Relative to WT, development rates were increased in both TNF-KO and TNFR-KO cells. Additionally, a sTNFR dose-dependent wake-like state was suggested by decreased SYN and SWP in TNFR-KO cells, but not in TNF-KO cells.
To our knowledge, this is the first demonstration of reverse TNF signaling in sleep/wake states. This provides a new way of viewing state regulation and associated potential clinical applications.

Abstract:

Developing new product applications for waste recycled from building construction and demolition (C&D) provides environmental and economic benefits. However, challenges remain for recycling certain low-value C&D materials, such as gypsum drywall waste, which is banned from landfilling in some areas due to hydrogen sulfide emissions during decay. The gypsum and paper components in drywall have low thermal conductivity relative to concrete and brick, suggesting a novel insulative masonry block system made from recycled gypsum drywall waste could have higher thermal performance than conventional concrete masonry units (CMU). The authors have developed such a system, referred to as Drywall Waste Block (DWB), and have previously published investigations of DWB engineering properties including compressive strength, water absorption, bulk density, and thermal conductivity. This paper describes investigation of resistance to heat flow of a reinforced DWB wall assembly, using a calibrated hot box apparatus as specified in ASTM C1363-11. The hot box apparatus was designed and fabricated as a cost-effective alternative to commercially testing services, affording rapid iteration during the research and development phase of novel building products made from unconventional materials. Some aspects of the apparatus design, fabrication, and characterization are discussed. Thermal performance of the DWB wall relative to a comparable CMU wall is discussed, as are areas for further research.

Abstract:

Merchandise sales are a crucial form of revenue and branding for sport teams. Major sport teams like Dallas Cowboys and New York Nicks rely on brand image for institutional recognition and revenue. In collegiate football, Washington State University possesses a strong football culture throughout the fanbase and community, encompassing thousands of spectators. Cougars fans come from near and far to support their football program, showcasing their dedication to the program and their individual fan identification through merchandise. Team identification, just as brand loyalty, produces an emotional connection with a sports team and results in a positive impact on the purchasing behavior of individuals. From the consumer’s perspective, purchasing and using team-licensed merchandise can strengthen the relationship between fans and the team, willing fans to showcase their support. Brand equity has been defined as a set of assets such as name awareness, loyal customers, perceived quality, and associations that are linked to brand; such as Washington State University Football. Brand awareness is the likelihood and ease that a brand name will be recognized The objective of this study was to contribute to existing research on consumer purchasing intentions, investigating the relationship of team success with consumer spending on merchandise. This study analyzes merchandise sales from the 2014-2015 WSU Cougars football season (losing season) and the 2015-2016 WSU Cougars football season (winning season). The analysis investigated the relationship between Coug Football performance and merchandise sales, exploring the relationship of team identification and perceived value.
