What Professors Would Like Their New Presidents to Know

New college presidents are faced with many challenges; some known and some unknown. With the frequency of new presidents entering from outside the institution, a challenge exists to understand the culture and current state of the institution. Existing faculty are uniquely positioned to provide assistance in this regard. What is presented here are perspectives on what college professors would like their new presidents to know. The information is provided in the form of common challenges to be aware of and suggestions to consider. Future directions are offered to delve deeper into the potential insights to be offered from the faculty lens to new, incoming presidents

Design, Fabrication and Evaluation of a Monochromatic Sensitometer

An intensity scale monochromatic sensitometer was constructed using a Bausch and Lomb single-pass diffraction-grating monochromator as the dispersing device. A ribbon-filament tungsten lamp was used to supply the radiant energy to the monochromator. The instrument was calibrated 2 radiometrically and was shown to have a maximum irradiance of 10 ergs/cm 2 2 at 425 nm, 43.7 ergs/cm at 550 nm and 26.1 ergs/cm at 700 nm. Exposure is accomplished by transporting the film and step tablet past a slit at a constant velocity. Several film velocities and slit widths are available to produce exposure times ranging from 0.003 to 2.0 seconds. Spectral sensitivity measurements were performed on KODAK Panatomic-X and KODAK High-Speed Infra Red materials. The results were compared to information supplied by the manufacturer. The differences between the Rochester Institute of Technology curves and the manufacturer\u27s curves were within 6 percent. The uncertainty in sensitivity of the materials being tested was found to be dependent on the local slope of the H and D curve at the density value selected for the determination of sensitivity

A computerized analysis of anterior teeth as a possible indicator of age, race and sex

Various systems of anthropometry have been developed through the years in an attempt to elucidate important characteristics of the human dentition. Few methods are currently relied upon as valuable indicators of age, race or sex; The computerized study of anterior tooth positions is an attempt at further elucidation of age, race and sex characteristics. Bite marks in wax from a general population sample of known age, race and sex are the basis for this computerized study. The computerized procedure allows for the examination of minute variation in tooth position. Twelve teeth in total are analyzed for every specimen

Defect and thickness inspection system for cast thin films using machine vision and full-field transmission densitometry

Quick mass production of homogeneous thin film material is required in paper, plastic, fabric, and thin film industries. Due to the high feed rates and small thicknesses, machine vision and other nondestructive evaluation techniques are used to ensure consistent, defect-free material by continuously assessing post-production quality. One of the fastest growing inspection areas is for 0.5-500 micrometer thick thin films, which are used for semiconductor wafers, amorphous photovoltaics, optical films, plastics, and organic and inorganic membranes. As a demonstration application, a prototype roll-feed imaging system has been designed to inspect high-temperature polymer electrolyte membrane (PEM), used for fuel cells, after being die cast onto a moving transparent substrate. The inspection system continuously detects thin film defects and classifies them with a neural network into categories of holes, bubbles, thinning, and gels, with a 1.2% false alarm rate, 7.1% escape rate, and classification accuracy of 96.1%. In slot die casting processes, defect types are indicative of a misbalance in the mass flow rate and web speed; so, based on the classified defects, the inspection system informs the operator of corrective adjustments to these manufacturing parameters. Thickness uniformity is also critical to membrane functionality, so a real-time, full-field transmission densitometer has been created to measure the bi-directional thickness profile of the semi-transparent PEM between 25-400 micrometers. The local thickness of the 75 mm x 100 mm imaged area is determined by converting the optical density of the sample to thickness with the Beer-Lambert law. The PEM extinction coefficient is determined to be 1.4 D/mm and the average thickness error is found to be 4.7%. Finally, the defect inspection and thickness profilometry systems are compiled into a specially-designed graphical user interface for intuitive real-time operation and visualization.M.S.Committee Chair: Tequila Harris; Committee Member: Levent Degertekin; Committee Member: Wayne Dale

Covid-19 & Mathematics Achievement: A Casual-Comparative Study

Learning loss due to COVID-19 and the digital divide will have dire consequences for low-income students. This study used the Faucet Theory (Alexander et al., 2001) as a theoretical framework to determine the extent that the COVID-19 learning environment impacted the Southern Public Schools District’s African American, low-income, and high-income high school students’ proficiency level based on the Algebra I section of the 2020-2021 Louisiana Education Assessment Program (LEAP) assessment. The researcher used archival data from the LEAP, a causal-comparative research design, and a one-way ANOVA to test the hypotheses and answer the research question. The results of the one-way ANOVA indicated that the pre-COVID-19 learning environment had no impact on African American, high-income, and low-income high school students’ average percentages at the mastery and basic proficiency levels, but it had a moderately negative impact on students’ average percentages at the approaching basic (p = .038) and unsatisfactory (p = .021) proficiency levels. The COVID-19 learning environment had no impact on African American, high-income, and low-income high school students’ average percentages at the advanced and basic proficiency levels, but it had a strong negative impact on African American, high-income, and low-income high school students’ average percentages at the mastery (p = .006), approaching basic (p =.007), and unsatisfactory (p = .008) proficiency levels. This study will give additional insights into COVID-19’s impact on the student achievement of a populace most susceptible to learning loss, high school students in a high- poverty school district. It will add to the current knowledge base on high-poverty school districts, distance education, learning loss, the digital divide, and student achievement in mathematics. The results showed that the COVID-19 learning environment widened the achievement gap between high and low income students and increased learning loss for students from specific backgrounds—African-American students and students in low-income households. This study is important because the researcher found that regardless of race or socioeconomic status, a blended teaching methodology of problem solving, individualized tutoring, game-based interaction, and computer assisted practice could significantly increase learning gains in mathematics, especially in cognitive areas. In fact, a blended learning environment could benefit low-performing students more than high-performing students
