University + Middle School = A Premier Professional Learning Community
No full textThis session will discuss how teachers from a middle school identify, define, and refine their understanding of their professional learning needs in the context of professional learning communities and how teacher candidates from a university learn in that context. Data shared with participants will include surveys, field notes, artifacts (journals, notes, other written contributions), and interviews with middle school teachers and teacher candidates
Tribological, Thermal, Kinetic, and Surface Microtextural Characterization of Prime p-Type \u3c100\u3e Silicon Wafer CMP for Direct Wafer Bonding Applications
Get PDFWe investigated the tribological, thermal, kinetic, and surface microtextural characteristics of chemical mechanical polishing (CMP) of 300 mm p-type \u3c100\u3e prime silicon wafers (and their native oxide) at various pressures, sliding velocities, and starting platen temperatures. Results showed the dominant tribological mechanism for both native oxide and silicon polishing to be boundary lubrication. Using frictional data, we pinpointed the exact time that corresponded to the total removal of the native oxide and the onset of silicon polishing. This allowed us to separately characterize removal rates of each layer. For native oxide, while the rate depended on temperature, the presence of a temperatureindependent shear force threshold and the low observed rates suggested that its removal by the slurry was dominantly mechanical. In contrast, for silicon polish, the absence of a distinctive shear force threshold and the fact that, for the same set of consumables, rates were more than 200 times larger for silicon than for native oxide suggested a dominantly chemical process with an average apparent activation energy of 0.34 eV. It was further confirmed that rate selectivity between native oxide and PE-TEOS based SiO2 control wafers was around 1 to 7, which underscored the importance of being able to directly measure native oxide removal rates. In all cases, we achieved excellent post-polish surfaces with Sa and Sq values of below 1 nm. Due to thermal softening of the thermoplastic pad at elevated temperatures, which we confirmed via dynamic mechanical analysis, overall process vibrations were significantly higher when platen heating was employed
Exploring the nexus of food citizenship and local food consumption in America\u27s rural-urban blend: Insights from Will County (Illinois)
Get PDFThis paper uses Will County in Illinois as a case study to examine the relationship between food citizenship and local food consumption in what we term to be the rural-urban blend of America. Food citizenship is participating in food-related actions promoting democratic, socially and economically equitable, and environmentally sustainable food systems. On the other hand, local food consumption is choosing and preferring to buy and eat local food over other conventional forms of food. The study used data analysis from a survey of 342 residents in Will County, Illinois, to test a conceptual model that considers various socio-psychological traits that food citizens might have, which could explain their preferences for local food, including local patriotism, perceived similarity with local farmers, social concern for the community’s well-being, and environmental concerns. The findings reveal the intertwined nature of local patriotism and place identity, shedding light on their direct influence on food citizens’ preferences. The perceived similarity with farmers and active engagement with local food producers deepen food citizens’ understanding and connection, ultimately influencing their preferences for locally sourced food. The study also highlights the distinct roles of men and women in local food preferences, with local patriotism being more significant for men aged 40 and above. Finally, the results underscore the Midwest’s unique socio-political landscape and the complex interplay of factors shaping local food preferences within ruralurban blends like Will County
Elevating microRNA levels by targeting biogenesis with steric-blocking antisense oligonucleotides
Get PDFMicroRNAs (miRNAs) are regulators of gene expression, and their dysregulation is linked to cancer and other diseases, making them important therapeutic targets. Several strategies for targeting and modulating miRNA activity are being explored. For example, steric-blocking antisense oligonucleotides (ASOs) can reduce miRNA activity by either blocking binding sites on specific mRNAs or base-pairing to the miRNA itself to prevent its interaction with the target mRNAs. ASOs have been less explored as a tool to elevate miRNA levels, which could also be beneficial for treating disease. In this study, using the PKD1/miR-1225 gene locus as an example, where miR-1225 is located within a PKD1 intron, we demonstrate an ASO-based strategy that increases miRNA abundance by enhancing biogenesis from the primary miRNA transcript. Disruptions in PKD1 and miR-1225 are associated with autosomal dominant polycystic kidney disease (ADPKD) and various cancers, respectively, making them important therapeutic targets. We investigated PKD1 sequence variants reported in ADPKD that are located within the sequence shared by miR-1225 and PKD1, and identified one that causes a reduction in miR-1225 without affecting PKD1. We show that this reduction in miR-1225 can be recovered by treatment with a steric-blocking ASO. The ASO-induced increase in miR-1225 correlates with a decrease in the abundance of predicted miR-1225 cellular mRNA targets. This study demonstrates that miRNA abundance can be elevated using ASOs targeted to the primary transcript. This steric-blocking ASO-based approach has broad potential application as a therapeutic strategy for diseases that could be treated by modulating miRNA biogenesis
Trauma-informed Assessment and Treatment of Domestic Violence
No full textIn the United States, 10 million people per year are physically abused by an intimate partner. This is an average of nearly 20 people per minute. While many counselors work with trauma, few have the training necessary to work with domestic violence (DV) clients. DV-specific trauma work deviates due to such factors as survival behaviors adopted by the client, continual assessment of lethality, preparing safety plans and working with the justice system. Understanding these specific elements are crucial to providing competent care to and safeguarding DV clients. This program will highlight specific factors of DV counseling including how it differs from universal trauma-informed care. The presenters will identify assessment flags, factors contributing to higher lethality in DV situations, safety planning strategies, and how to conduct a trauma-informed session
