Effects of Teacher Training in Trial-Based Functional Analysis via Video Modeling

Trial-based functional analysis (TBFA) is an efficient strategy for assessing challenging behavior in the classroom and a necessary step in developing effective functional assessment- based interventions (FABI). However, researchers have identified several barriers limiting the applicability of this practice in schools, including difficulty in (a) training teachers to mastery; (b) assessing whether teachers can implement this practice independently, with fidelity, in natural settings; and (c) determining whether teachers can use functional analysis (FA) to identify functions of problem behavior and develop effective interventions. This study will address these gaps in the literature by using a novel approach for training teachers to implement TBFA and develop subsequent behavior plans. Video modeling is an evidence-based practice for helping children in school-based settings acquire new skills, and has some evidence supporting its use with teachers. This study assessed the effects of using video self-modeling in training teachers to conduct TBFA in classrooms. The primary dependent variable was treatment fidelity of teacher implementation of TBFA. Additional analyses included teachers’ ability to use student data to identify the function of problem behavior and develop appropriate FABI

\u3cem\u3eKickin’ Sand and Tellin’ Lies\u3c/em\u3e: The Creation of a Sound Design

The fictional tale Kickin’ Sand and Tellin’ Lies by Jackson Miller and Chris Forrer culminated the collaborative research project Launching through the Surf: The Dory Fleet of Pacific City, involving the Pacific City Dorymen’s Association, the Pacific City Arts Association, the Department of Theatre and Communication Arts at Linfield College, the Jereld R. Nicholson Library, and the Linfield Center for the Northwest. Drawing from interviews conducted by students and faculty members, professor Jackson Miller and senior Chris Forrer penned a playscript exemplifying the lifestyle of Pacific City dory fishers. The design concept for the theatre production was to deliver the community’s tales in a realistic environment. Themes of the production include strength in community, history of the Oregon Coast, and fishing as a business. As the sound designer, I achieved the concept and conveyed the themes by building cues with effects collected in field recordings at Pacific City. This project details the creative process from concept to finished sound cues within the production

Developing a dual-layer system for the mitigation of tin whiskers

There are very few studies that have investigated directly the effect of an oxide film on tin whisker growth, since the cracked oxide theory was proposed by Tu in 1994. The current work has investigated the effect of using an electrochemically formed oxide and both a molybdate conversion coating and a tungstate conversion coating on tin whisker growth from Sn-Cu electrodeposits on Cu, and compared it with that from a native air-formed oxide. X-ray photoelectron spectroscopy (XPS) has been used to investigate the effect of coating parameters on the thickness and composition of the oxide film. The XPS studies show that the oxide film formed using either of the conversion coating baths was significantly thicker than that produced from the potassium bicarbonate-potassium carbonate bath. Initial observations suggest that both the tungstate-based conversion coatings and the molybdate-based conversion coatings significantly reduced whisker growth by over 80 %, compared with a native air-formed oxide, and provide improved whisker mitigation compared with the electrochemically formed oxides. The current work has also investigated the potential of using a dual-layer system, comprised of both an electrochemically formed oxide bottom layer and an acrylic conformal coating top layer, for the mitigation of tin whisker growth. The electrochemically formed oxide used in the dual-layer system was produced at 2 V vs. Ag/AgCl while passing a charge of 60 mC cm-2 and the thickness of the conformal coating was aimed to be between ~5 μm to ~6 μm. This thickness was chosen to enable the study of whisker growth on a shorter time scale and to study the effect the electrochemically formed oxide had when used in conjunction. Initial observations showed that the dual-layer system provided improved whisker mitigation compared with both the electrochemically formed oxides and acrylic conformal coatings when used singularly. As part of the self-healing work, nanocapsules filled with the reactive agent were needed to be synthesised and the compatibility of them with different solvents needed to be studied. Capsules filled with the reactive agent were successfully synthesised, however, it was found that the capsules agglomerated and the size of the capsules, in some instances, were too large to be incorporated into a thin conformal coating. Regardless, the capsules were still analysed to check the compatibility with different solvents, to identify a suitable conformal coating mixture that would not dissolve the polymer shell of the capsules. It was observed that the capsules were stable in three out of the five solvents that were analysed, them being isopropanol (IPA), butanone and methylcyclohexane
