Projections and Perceptions-Editorial Comments. The Changing Importance of College and University Teaching: The 1960s Versus the 1990s, James O. Wheeler (University of Georgia)
Get PDFApproximately thirty years ago, when I was just starting graduate school in geography, one of the first impressions I gained was the low priority accorded teaching. The emphasis, instead, was on research. The attitude was that anyone could teach but not everyone could do hotshot research. In fact, I got the impression that professors who were so wrapped up in research that their lectures were disorganized and confused were admired more than professors who did little or no research but whose lectures were superb. (There were, of course, inexplicably, those rare professors who did both remarkably well.) In general, poorly prepared lectures were the hallmark of those professors who were dealing with the more lofty and profound research issues of the day. Even professors who had no lofty ideas sought to fool the students by delivering poorly prepared lectures. It was the absentminded, distracted, befuddled, and therefore brilliant professor who was most admired. When I was leaving graduate school for an academic position, I was advised to devote as little time to teaching as possible. Only research counts at a university, I was warned. Just wing your way through the class. No one will remember what you said in class, but they can see what you have published. And so on
Late Holocene Coastal and Estuarine Environments of the Shanghai Area, People\u27s Republic of China
Get PDFFour major sedimentary environments have been identified in the Shanghai area which were deposited over the past 7,000 years, 3 to 20 meters above a Pleistocene basal clay. These are marsh, lagoon, recurved spit and tidal flat. The morphology west of Shanghai is a fresh water marsh since it was not transgressed by rising Holocene sea levels. In the central area, a recurved spit and lagoon had developed from 6,500 years B.P. to 3,500 years B.P. However, the tidal flat has characterized coastal sedimentation in the eastern part of Shanghai since 3,000 years B.P

Comparing Diabetes and Hypoglycemia Mortality Rates
No full textAround the world, hypoglycemia and diabetes morality has been on the rise. This study aims to explore the difference between hypoglycemia and diabetes related morality on a global scale. Knowing the mortality rate of diabetes and hypoglycemia would be useful for countries needing to know what they should be doing differently to tackle this issue. The data was found on Mendeley Data and is called “Global proportions and rates of hypoglycemia-related morality” by Francesco Zaccardi. They focused on proportions of hypoglycemia related deaths (compared to total diabetes deaths) and counts of hypoglycemia and diabetic related mortalities across 109 different countries. Descriptive statistics and frequency tables were generated for the variables of interest. Two data sets were merged to have one file that contained hypoglycemia, diabetes and population counts. Two new variables were then computed to show the incidence rates of hypoglycemia and diabetes. There were higher mortality rates shown in Japan, Latin America and Caribbean countries. And lower mortality rates in Europe, North America, and other high-income regions. We can see which countries with lower mortality rates and follow their practices to help lower countries with higher mortality rates. Some policy suggestions could be to improve diabetes management and monitoring, strengthen healthcare access, and to enhance death certification accuracy. Policy makers should improve death certification is because lower income countries may not have the correct data, which in turn creates a lack of focus on the issue. This is also one of the notable limitations when trying to help diabetics across lower income countries. To summarize, the study shows us geographic differences between hypoglycemia and diabetes related mortality rates across 109 countries
Molecular Visualization Laboratory (BIOL4450): Biosynthetic Pathway of Flavonoid 3\u27-O-methyltransferase
No full textFlavonoids are diverse plant metabolites essential for plant defense, pigmentation, and UV protection. These compounds, including flavanol’s, flavones, and isoflavonoids, offer various health benefits in human health due to their antimicrobial, anti-inflammatory, and antioxidant properties. O-methylation is an essential modification in flavonoid biosynthesis, mediated by methyltransferases such as flavonoid 3\u27-O-methyltransferase (FOMT). This post-synthetic modification enhances the compounds\u27 lipophilicity and bioactivity. S-adenosylmethionine (SAM or AdoMet) is the methyl donor in these reactions, contributing to the structural diversity of flavonoids and their specialized metabolic roles. These biosynthetic processes are crucial for plant adaptability, defense mechanisms, and potential healthcare applications, particularly in developing plant-based therapeutics. The flavonoid biosynthetic pathway involves the enzymatic activity of methyltransferases, which modify flavonoids, enhancing their role in plant-specialized metabolism. These phytochemicals, such as erythritol and caffeic acid, are critical for the plant\u27s response to environmental stressors. Understanding these processes provides insights into molecular evolution and the structural basis of flavonoid modification. To further investigate the structural mechanisms, we employed methods such as gene expression in Escherichia coli, protein purification, and 2D gel electrophoresis to further investigate the structural mechanism of FOMT. Utilizing augmented reality (AR) and virtual reality (VR) technologies to visualize enzyme-substrate interactions enhances the understanding of catalytic processes. X-ray crystallography further supports this by revealing the 3D structure of these enzymes. This innovative approach, combining STEAM (Science, Technology, Engineering, Arts, and Mathematics), fosters creativity in exploring biological processes. By integrating molecular biology techniques, bioinformatics, and visualization technologies, it highlights the potential of flavonoid biosynthesis for advancements in agricultural biotechnology and holistic health science, enhancing both biomolecular discovery and educational experiences
Pre-Twisted Molecular Geometry\u27s Effect on the Optical Properties of Nitrophenyl Substituted Polycyclic 1,2-BN-Heteroarenes
No full textIncorporating a three-coordinate boron center into the structure of polycyclic aromatic hydrocarbons by replacing one of the C=C bonds with a B-N bond creates a more planar scaffold. These flat-structured heterocycles partially substituted with a boron-nitrogen bond known as aromatic azaborines, are highly regarded for their unique optoelectronic properties such as photochemical stability, high molar absorption coefficient, and high fluorescent quantum yields, as well as large Stokes shifts and tunable absorption/emission spectra, making them excellent candidates for a variety of applications such organic light-emitting diodes (OLEDs). Adding a -NO2 group as a strong electron-accepting group to the scaffold of aromatic azaborines, particularly pyrrolinone-fused-1,2-azaborines (PFAs), in an effort to redshift their absorbance and emission and create electron-deficient n-type organic conjugates, results in significant emission quenching due to intersystem crossing. Another issue with -NO2-substituted PFAs is that they aggregate at high concentrations due to strong intermolecular π-π stacking interactions. In turn, aggregate formation causes emission quenching, also known as Aggregation-Caused Quenching (ACQ). This practical limitation poses significant challenges for -NO2-substituted PFAs’ use in many applications. We hypothesized that increasing the steric interactions through the PFA scaffold and creating a larger twist in the molecular geometry by including bulkier moieties such as methyl group will result in -NO2-phenyl substituted PFAs with aggregation-induced emission (AIE), solvatochromism and thermochromism properties. These findings will aid in the development of more improved future AIE-active PFAs, as well as the understanding of how molecular geometry influences these compounds\u27 optoelectronic properties
Numerical Analysis of Transonic Performance of a Compound Delta Wing
No full textTransonic flight holds paramount significance in the domain of global air forces. The efficacy of delta wings in supersonic flow conditions has been widely acknowledged. This success is primarily attributed to their low wing thickness, which serves to mitigate wave drag. But fighter aircraft mainly operate and maneuver at transonic speeds. Additionally, delta wings exhibit a vortex lift phenomenon, stemming from the generation of leading-edge vortices at elevated angles of attack. Consequently, since the 1950s, military aircraft have extensively employed delta wing configurations. While maneuvering at transonic speeds delta wings encounter a phenomenon termed vortex breakdown at heightened angles of attack. Vortex breakdown manifests as the rupture of leading-edge vortices, resulting in diminished lift and altered aerodynamic behavior. This research endeavors to deepen our comprehension of vortex breakdown evolution over a compound delta wing configuration. Numerical simulations were employed to scrutinize the flow dynamics over the wing. These simulations encompassed a Mach number range spanning from 0.6 to 1.0, coupled with angles of attack varying from 0° to 15°. The simulations were executed utilizing Reynolds-Averaged Navier–Stokes transient computations due to the flows unsteady nature, supplemented by the Spalart-Allmaras turbulence model. The findings reveal that compound delta wings exhibit vortex breakdown, particularly at elevated angles of attack. This investigation contributes essential insights into the mechanisms underlying vortex breakdown over compound delta wings, laying the groundwork for future investigations aimed at devising strategies to delay vortex breakdown and control its formation
Immersive Virtual Reality Program for Parent Home Safety Education to Prevent Child Injury
No full textInjury is the leading cause of death in children under the age of six in the U.S., creating a large public health challenge and a call to action to reduce rates of injury deaths. In 2021, \u3e1 million emergency room visits and \u3e2800 deaths occurred among children under 6 due to unintentional injuries. With most incidents taking place at home, evidence-based parenting programs (EBPP) are a key opportunity to reach parents with injury prevention education, and ultimately to improve outcomes. Parent home safety education has been largely driven by written materials, such as pamphlets, which lack engagement and application. To introduce behavior change, and apply learning concepts in real-world contexts, novel approaches are needed. Using immersive virtual reality (IVR), our team is developing a home safety program for parents of young children aiming to simulate a home environment, allowing parents to learn and practice their home safety and supervision skills without introducing real risk. Behavior change requires skill practice; IVR lends itself to this type of practice, making behavior change more likely. The IVR program can increase parent engagement and can be disseminated to the network of EBPPs in the U.S., many of which have federal funding allotted for them. In line with Human-Centered Design, two phases will be conducted: (1) Design/Ideate, (2) Prototype. Phase 1consists of interviews and focus groups with EBPP providers and parents to obtain feedback on the program. Phase 2consists of beta testing (n=5) and a pilot trial (n=10) of the prototype. We will collect data on parents’ home safety knowledge, ability to identify hazards in a physical space, and user experience. We will assess sustained program impacts by collecting data three months post-baseline. This pilot study will aid in preparation for larger studies and broader program development to ultimately reduce child injury

No full textThe gaming industry has experienced rapid growth, with esports and live-streaming platforms like Twitch becoming prominent forces. Twitch, specializing in gaming content, has witnessed a surge in popularity, particularly during the COVID-19 pandemic. Analyzing the dynamics of the platform and the preferences of its audience is crucial for understanding its success. This study investigates the relationship between follower count and average viewership on Twitch, aiming to identify key factors influencing streamer popularity and inform strategies for both streamers and platform developers.
This study employs a quantitative research approach, analyzing data from a sample of 1,000 top Twitch streamers over the course of a year. Key variables include follower count, average viewership, content type, streaming schedule, audience interaction metrics, and demographic information. We hypothesize a positive relationship between follower count and average viewership, suggesting that streamers with higher average viewership are more likely to attract a more significant following. Additionally, the research anticipates that factors such as content type, audience interaction, and viewer demographics will significantly influence streamer popularity.
Descriptive statistics will be used to analyze the distribution of variables and identify trends. Correlation analysis will assess the relationship between follower count and average viewership, while regression analysis may explore the impact of additional factors. We anticipate a positive relationship between follower count and average viewership, supporting our hypothesis. Additionally, we expect to identify significant predictors of streamer popularity.
The findings can benefit streamers by informing their content strategy and audience engagement. Platform developers can use these insights to enhance the user experience. Researchers can gain a deeper understanding of the online entertainment landscape. Future research may explore additional factors influencing streamer popularity, such as social media and collaborations. This will contribute to a more comprehensive understanding of the dynamics driving the live-streaming industry
