Historical and Regional Pronunciations in Vocal Performance
RILM: Particular pronunciations or dialects are important factors in the creation and execution of vocal music. Such sounds can have a dramatic effect on the coloration and rhythmic profile of a piece of music; the recreation of such sounds is thus of great importance

Detection of benzotriazole and related analogues in surface samples collected near an Ohio airpark
Benzotriazoles are a class of contaminant of emerging concern which are commonly used as anticorrosive agents in aircraft deicer and anti-icing fluids (ADAFs). The analogues 1H-benzotriazole (BTZ), 4-methyl-1H-benzotrizole (4m-BTZ), and 5-methyl-1H-benzotriazole (5m-BTZ) are commonly found in environmental occurrence together. The two methylated isomers, collectively known as tolytriazole (TTZ), have different toxicity and stability. These contaminants are highly water soluble and resistant to biodegradation, making them persistent through water treatment. Benzotriazoles have been detected worldwide; this investigation focuses on monitoring three sites near a small airpark in Wilmington, Ohio. Two sites that receive runoff from the airpark, Lytle Creek and Indian Run, have been under investigation for decades due to documented poor water quality issues. This investigation adds to data from the two previous years documenting an increase in BTZ compounds that corresponds to an increase in activity at the airpark by an online retailer. Solid Phase Extraction (SPE) was used to isolate benzotriazoles from surface water samples. Liquid Chromatography/Mass Spectrometry (LC/MS) was used for separation and detection of analytes. Each consecutive monitoring season detected more BTZ and TTZ on average than previous seasons. The 2021 season detected TTZ from 0.346-1.785 µg/L at Indian Run. Lytle Creek yielded BTZ from 0.051-0.158 µg/L and TTZ from 1.700-51.87 µg/L. Other occurrences have detected BTZ compounds associated with airpark runoff ranging from ng/L to mg/L. Gas Chromatography/Mass Spectrometry (GC/MS) was employed to separate the two TTZ isomers that could not be separated by LC/MS. This method revealed a ratio of 41.29% 4m-BTZ and 58.71% 5m-BTZ in selected water samples, a ratio which is similar to findings in a Wisconsin study. Based on the ratios of each isomer, hazard quotients assessed most samples analyzed as low environmental risk with a few days presenting medium to high environmental risk. Sediment samples were also examined for presence of benzotriazoles, but the results were inconclusive

Recognition of asset impairment: A Comparison of Recognition Criteria
This report examines the accounting for the impairment of long-lived assets and identifiable intangibles as discussed in the Financial Accounting Standards Board Discussion Memorandum No. 098-B. This report specifically analyzes the recognition criteria to be used in determining when an impairment exists. The economic, permanence, and probability criterion are compared and contrasted to ascertain which method is the most feasible. The relevant information for this study ~came from the discussion memorandum, Big Six accounting firms, published literature, and a national student seminar on the topic. The study revealed a great deal of ambiguity in accounting for assets whose value has diminished due to corporate restructuring. This uncertainty has lead to confusion and mistrust among financial statement users. There is, however, a solution to this problem. The use of the probability criterion in recognizing and recording impairments provides adequate disclosures and timely information.B.A. (Bachelor of Arts
