There are substantial concerns regarding academic integrity during online test taking, which sacrifices much of the instructor's control over the testing environment in favor of allowing students the asynchronous flexibility that is essential in courses administered online. Video proctoring software has been a key technology for returning some control over the testing environment to the instructor. The authors analyzed the change in grade distributions across 29 courses and instructors on a college campus before and after video proctoring was made widely available. They found that the average course grade point average scores were significantly reduced after the adoption of the proctoring software, suggesting that academic integrity is compromised when online exams are left unproctored. Advances in technology, computers, internet access, and pedagogical tools have contributed to raising the quality of the educational experience of distance or online learning to match that of traditionally taught courses. A meta analysis by the U.S. Department of Education (2010) concluded that courses taught online and in a blended learning format were increasing in popularity and, if properly implemented, were as likely or more likely to promote student learning as traditional formats. This conclusion bodes well for the increased interest and acceptance of online education. The Online Learning Consortium reported that nearly 30% of all students in 2015 took at least one online course, which totalled over six million stu

However, few studies have explored gender differences involving the link between hearing levels and frequency of exposure to noise, hearing protection, duration and intensity level of personal listening device (PLD) use, and fitness factors across the lifespan. Methods: Data were analyzed from 115 males and females (ages 18 to 84) recruited from Oxford, Ohio. Participants were separated into two groups: PLD-users and PLD non-users, depending on their usage. Both groups completed audiometric and health-related fitness testing. Results: Males were more likely to listen to music at potentially harmful levels (85 dBA) in silence (p= 0.002). Although the majority of participants listened at “safe” levels, males were more likely to listen at louder and potentially dangerous levels in silence than females. Waist-to-hip ratio was positively correlated with hearing levels in both genders. Only 23% of participants reported using hearing protection: half female, half male. Participants who used PLDs for a greater number of years had better traditional frequency hearing thresholds than non-PLD users. Conclusion: A majority of those who have been using PLDs for a greater number of years are younger adults whose hearing acuity has not yet been greatly affected by degenerative effects of aging. Medical advancements and improved fitness levels may protect the younger generations’ hearing acuity as they age. Gender differences related to hearing loss can provide valuable information about risk factors for developing hearing loss throughout aging.

One challenge is the perception that academic integrity associated with online tests is compromised due to undetected cheating that yields artificially higher grades. To address these concerns, proctoring software has been developed to address and prevent academic dishonesty. The purpose of this study was to compare online test results from proctored versus unproctored online tests. Test performance of 147 students enrolled in multiple sections of an online course were compared using linear mixed effects models with nearly half the students having no proctoring and the remainder required to use online proctoring software. Students scored, on average, 17 points lower [95% CI: 14, 20] and used significantly less time in online tests that used proctoring software versus unproctored tests. Significant grade disparity and different time usage occurred on different exams, both across an...

This suggests the need for specific biomarkers (a) to elucidate the biochemical nature of DNA lesions and their repair and (b) to monitor noninvasively the generation and removal of DNA damage in biological systems. Several types of damage are known to result from the interactions of free radicals with chromatin, including single- and double-strand breaks, base and sugar alterations, and DNA-protein crosslinks.5 Each of these types of damage seems to be amenable to chemical analysis by the techniques of high performance liquid chromatography (HPLC), gas chromatography/mass spectrometry (GC/MS), alkaline and neutral elution, and other chromatographic and filter techniques. Of particular interest have been the measurements of specific products of oxidative damage to DNA and proteins, such as thymine glycol, thymidine glycol, base-amino acid crosslinks, and altered amino acids. Recently, the measurement of thymine glycol (TG), thymidine glycol (dR-TG), and 5-hydroxymethyluracil (HMU) in urine has been suggested to be a suitable approach for the in situ assessment of oxidative DNA damage caused by every day metabolic processes.References
