Self-monitoring Among Secondary and Post-secondary Students With Intellectual and Developmental Disabilities: Current Summary and Future Directions

Research presented at the 2020 Georgia Educational Research Association Conference, virtual conference. A preliminary search of the literature has revealed very few studies applicable to self-monitoring behaviours in college-aged individuals with intellectual and developmental disabilities (IDD), a technique that has been studied primarily in the elementary aged population. Learning how to self-monitor, whether it is self-monitoring behaviour or using it to learn to do tasks, is an important skill for one to become a success in college and during adulthood. This skill may allow some students to seek out and successfully complete further education and vocational training. Having individuals with disabilities able to join the workforce and advanced educational opportunities will increase their visibility, increase their opportunities for community involvement, and hopefully reduce stigma against people with disabilities. Unfortunately, there are significant gaps in the literature on self-monitoring for students with IDD who are attending post-secondary institutions. This presentation will provide an update on the current status of research on this topic as well as discuss the future directions

Instant Two-Body Equation in Breit Frame

A quasipotential formalism for elastic scattering from relativistic bound states is based on applying an instant constraint to both initial and final states in the Breit frame. This formalism is advantageous for the analysis of electromagnetic interactions because current conservation and four momentum conservation are realized within a three-dimensional formalism. Wave functions are required in a frame where the total momentum is nonzero, which means that the usual partial wave analysis is inapplicable. In this work, the three-dimensional equation is solved numerically, taking into account the relevant symmetries. A dynamical boost of the interaction also is needed for the instant formalism, which in general requires that the boosted interaction be defined as the solution of a four-dimensional equation. For the case of a scalar separable interaction, this equation is solved and the Lorentz invariance of the three-dimensional formulation using the boosted interaction is verified. For more realistic interactions, a simple approximation is used to characterize the boost of the interaction.Comment: 20 pages in revtex 3, 3 figures. Fixed reform/tex errors

Development of Magnetic Inspection Techniques for Evaluation of Fatigue Damage and Stress in Low Alloy Steels

It is known that the magnetic properties of ferromagnetic materials change under fatigue and applied loads (1,2,3). These changes in the magnetic properties could be used as indicators of the stress state of the material, or possibly for predicting the remaining fatigue life. Previous reports have shown successful implementation of this magnetic measurement technique for NDE of steel samples in a laboratory enviroment. However, for this technique to be practical, a field-usable instrument must be developed. This paper will describe measurements using one such instrument, the Magnescope. It will also discuss the techniques used to evaluate the effects of applied loads, both tensile and compressive, and low cycle fatigue on a variety of materials

Does tiny-scale atomic structure exist in the interstellar medium ?

We report on preliminary results from the recent multi-epoch neutral hydrogen absorption measurements toward three pulsars, B0823+26, B1133+16 and B2016+28, using the Arecibo telescope. We do not find significant variations in optical depth profiles over periods of 0.3 and 9--10 yr, or on spatial scales of 10--20 and 70--85 AU. The large number of non detections of the tiny scale atomic structure suggests that the AU-sized structure is not ubiquitous in the interstellar medium and could be quite a rare phenomenon.Comment: Accepted by ApJ Letters, 5 pages, 2 figure

Magnescope: Applications in nondestructive evaluation

This paper describes recent results obtained with the Magnescope, which has been used on location in industrial environments and has successfully detected impending fatigue failure, creep damage, applied stress, and microstructural differences. It is concluded that the device provides a useful nondestructive method for evaluating the mechanical properties of materials through the measurement of their structure sensitive magnetic properties
