Understanding the Research and Practical Implications of Artificial Intelligence in Educational Leadership and Policy: A Systematic Review
No full textConsiderable attention has been paid to artificial intelligence (AI) in the field of education generally; however, much fewer studies address educational leadership and policy studies (ELPS) specifically. Given the increasingly widespread use of AI, there is a growing need to examine the implications for ELPS research and practice. In this systematic literature review, we examine studies related to AI in ELPS to uncover the implications for research and practice in the field. Our results demonstrate the need for more empirical research on AI in ELPS, particularly as it relates to guiding practice in the field
Characterizing Differential Reflectivity Calibration Dependence on Environmental Temperature Using the X-band Teaching and Research Radar (XTRRA): Looking for a Relationship between Temperature and Differential Reflectivity Bias
Get PDFCalibration scans are important for the maintenance of data and the quality of the information that radars output. In this study we looked for a temperature dependency in a full year’s worth of differential reflectivity (ZDR) calibration scan data collected by the X-band Teaching and Research Radar (XTRRA) located near the Purdue University campus. In a vertically pointing calibration scan, the radar scans the drops from below while rotating. From this angle, the overall shape will be circular, which corresponds to a ZDR value of approximately 0 dB. To process the data for the year 2021, a Python script was written to be used by the students in Radar Meteorology (EAPS 523) as part of their Course-based Undergraduate Research Experience (CURE). The ZDR mean values were then compared to the temperature data from the FAA Automated Surface Observing System (ASOS) station located at the Purdue Airport in West Lafayette (KLAF). In cases where temperatures changed quickly diurnally, the ZDR mean changed inversely to temperature, a quick rise in environmental temperature corresponded to a decrease in ZDR mean relative 0 dB, and vice versa. A positive correlation of 0.79 indicated a relationship between ZDR and temperature. The XTRRA is housed in a radome and has temperature regulation via the internal air conditioning systems in Wang Hall. We speculate that there isn’t a stronger relationship due to the KLAF ASOS station experiencing more solar radiation and therefore being warmer than the cooled radar, as well as the fact that XTRRA and the station are situated 3.6 km apart
Genome-Wide Mutagenesis to Investigate the N-Terminal Methylome: The Protective Effects of Hsp31 and Other Methylated Proteins in Yeast
Get PDFThe purpose of this study was to understand the role of methylation in regulating the cellular stress response of Hsp31 in Saccharomyces cerevisiae yeast cells. Hsp31 is known to be methylated by the N-terminal methyltransferase Tae1. Changing the methylation site can affect the methylation status of Hsp31, which may play a role in the protective activity of Hsp31 against cellular stress. GLO1 is a gene in yeast involved in catalyzing the detoxification of methylglyoxal (MGO), which is a by-product of glycolysis. We established that S. cerevisiae in the glo1Δ and background is sensitive to cellular stress by MGO. Mutant strains in the glo1Δ background will simulate methylation levels, which can be used to determine if methylation increases or decreases the protective activity of Hsp31 under cellular stress. Hsp31 overexpression successfully rescues mutants in the glo1Δ background when treated with MGO. In a high throughput screen using CRISPR-based technology from Inscripta (Boulder, Colorado), a biotechnology company, we aim to replicate the results we observed in the glo1Δ background and potentially uncover new phenotypes in a series of experiments that will investigate the role of methylation in cellular processes in addition to oxidative stress, including heat stress and protein synthesis. The Inscripta library will allow us to collect data from approximately 1,000 mutants simultaneously rather than completing the experiment for each mutant individually. These results will provide much greater insight as to how methylation globally affects the cellular processes involved in the protective activity of Hsp31 and other substrates in S. cerevisiae
