Student-Faculty Collaborative Research Grant Report
No full textFunds were requested to support one student to investigate the development of silica sol-gel based materials containing silver-nanoparticles (NP) as possible chemical sensors by observing surface enhanced Raman spectroscopic (SERS) changes in the spectrum of a target compound, 3,3’-dihexyloxacarbocyanine iodide. The organic fluorescent dye, 3,3’- dihexyloxacarbo-cyanine iodide (DiOC6(3)), was chosen as a target molecule for detecting distinguishable SERS signals and as a basis for Ultraviolet-Visible (UV/Vis) Spectroscopy in base-catalyzed and acid-catalyzed silver colloid sol-gels because of its facilitating ability to stain and identify mitochondrial changes during early apoptosis in animal and plant cells, and for its capability to stain and visualize thrombus formation in red blood samples.
Sean Webster was the lead student investigator on this project and worked closely with me to develop working protocols to carry out the investigation. This project builds upon my previous research involving the development of new host materials for chemically active probes that can be used as sensors. The goals of this project were twofold: 1) to develop new SERS actively labeled NP materials, and 2) to investigate the spectroscopic changes that can be detected by (SERS) in different environments that may lead to possible sensors or drug delivery applications
crisscrossing Science Episode 117: Eusocial Insurrections
No full textIn this episode, Mike Crosser (professor of physics at Linfield University) and Chad Tillberg (professor of biology at Linfield University) discuss insurrections in the insect world. Tillberg explains how these insurrections happen and how they are dealt with by insects
Tilings of Modified Rectangles by Ribbon-Tile Pentominoes
Get PDFWhich dimensions of a and b satisfy tilings of modified rectangles by ribbon tile pentominoes? We answer this question using tile invariants developed in prior research on the mathematics of tiling, as well as the use of inductive lemmas. The set of tiles we use for this study are height-1 ribbon tile pentominoes, which we later define. Modified rectangles are a-by-b rectangles with height a and width b, and the additional feature that the top left and bottom right squares are removed
Disaggregated Phillips Curve Regression
Get PDFThis project estimates the Phillips curve using disaggregated US data. The panel model for this project was created using relative unemployment rates and metropolitan regional price parities for all items (RPP) for each state from 2008-2018. The relative unemployment rate was created for each state by taking the state level of unemployment and dividing it by the US national unemployment rate. The metropolitan price parity was created by taking the Consumer Price Index (CPI) for all metropolitan areas in a state and a dividing it by the US national CPI for all metropolitan areas in the US. The dependent variable is metropolitan RPP, and the independent variables are the relative unemployment rate, a lagged unemployment rate, and a lagged metropolitan RPP. During the time-period of 2008-2018, the results suggest there is an inverse relationship to the disaggregated Philips Curve. However, the aggregated Philips Curve is flat over this same time period. I discuss why a disaggregated approach allows for identification of the Phillips curve that is not found using aggregate data
Kū’ē: Sovereignty and Violence
No full textWestern sociologists, philosophers, and political scientists alike agree that sovereignty is intimately related to the legitimate capacity for violence. These same scholars rarely consider the colonial context of the United States and the persistent injustices faced by the historically occupied and colonized. When is violence permissible? How does Indigenous sovereignty impact the moral legitimacy of violence? My conceptual analysis is in the context of the historical pattern of US assimilationist tactics and considers radical political thought on violence, sovereignty, and justice. I argue that violence may be permissible when utilized by Indigenous peoples and can be used strategically to decolonize occupied territories
What Is an Adult?: A Prototype Analysis of Attributes of Adulthood
Get PDFEmerging adulthood is described by Arnett (2000) as a recent developmental period, between the stages of adolescence and young adulthood. To understand the transition into adulthood, it is necessary to understand the definition of what an adult is, from the perspective of the general public. In the current study, a bottom-up approach is used to understand people’s perceptions of adulthood through a prototype analysis, a procedure modeled from Kearns and Fincham (2004). 122 participants were recruited through snowball sampling on social media sites and classroom advertisements. Participants ranged from 18-62 years old. They completed an online questionnaire asking: “What is an adult? Please list all the attributes of an adult that come to mind.” Participants listed up to 20 attributes each. The attributes are categorized based on similarities of linguistic units. The importance of this exploratory study is to contribute to the literature of perceptions of adulthood. It could also have potential to be applied in intervention work designed to help adolescents through the transition to young adulthood
First, But Certainly Not Last: First-Generation Student Experiences
No full textIn this four-part podcast, co-hosts Rosario Rucoba and Patricia Bocanegra Sanchez explore what it means to be a first-generation college student. They discuss the topics of adversities first-generation students may face, what it is like being a non-traditional student, how to be a first-generation leader on campus, how to embrace the first-generation label, and so much more
