The Dilemma Of The Senior Woman Administrator Role In Intercollegiate Athletics, Jennifer Hoffman
The Dilemma Of The Senior Woman Administrator Role In Intercollegiate Athletics, Jennifer Hoffman
Journal of Issues in Intercollegiate Athletics
All National Collegiate Athletic Association (NCAA) member institutions designate the highest-ranking woman in athletic administration the senior woman administrator (SWA). This role is “intended to encourage and promote the involvement” of women in decision-making, enhance the representation women’s experiences and perspectives, and support women’s interests in intercollegiate athletics (NCAA, n.d. [a]). However, previous research reveals inconsistency in the tasks and responsibilities associated with the SWA role. Furthermore, it is not well established if this role is a mechanism to advance women to leadership roles or a terminal position (Hatfield, 2009). To better understand the influence of the SWA role on …
Academic Majors Of Upperclassmen Football Players In The Atlantic Coast Conference: An Analysis Of Academic Clustering Comparing White And Minority Players, Jeffrey J. Fountain, Peter S. Finley
Academic Majors Of Upperclassmen Football Players In The Atlantic Coast Conference: An Analysis Of Academic Clustering Comparing White And Minority Players, Jeffrey J. Fountain, Peter S. Finley
Journal of Issues in Intercollegiate Athletics
Studies on graduation rates of college athletes have typically utilized subdivisions based on race, gender, and sport to allow for more transparent scrutiny of potential problem areas. However, subdivision by race has not been utilized when examining clustering of football players into academic majors. Clustering occurs when 25% or more of an athletic team shares a single academic major (Case, Greer, & Brown, 1987). Football media guides from Atlantic Coast Conference (ACC) schools were utilized to determine the academic majors of upperclassmen to explore whether race could be a factor in academic clustering. The results showed that Minority players were …

Social media users benefit from a more personalized and interactive connection with public figures and others they engage with via social media. However, such engagement requires active effort from the public figure and can only occur when the celebrity is available for such sessions. This disclosure describes techniques, implemented with specific user permission, to train an artificial intelligence (AI) model based on user data of an individual or entity. The trained model can represent the individual’s personality and engage in online interactions on behalf of the individual or entity with users of a social media platform, a messaging/chat service, audio …

Synthesis, Characterization, And Bslt Test Of Pyrazoline And Pyrazole Compounds From Chalcone Using Microwave Irradiation, Siska Elisahbet Sinaga, Matius Paundanan, Yum Eryanti
Chimica et Natura Acta
Pyrazole is an organic compound, classified as an alkaloid, featuring a heterocyclic five-membered ring structure composed of three carbon atoms and two adjacent nitrogen atoms, forming an endocyclic double bond. Pyrazole has various biological activities, such as antibacterial, anticanc er, antiinflammatory, antidepressantion, and antioxidant. Pyrazole 2-(5-(4-chlorophenil)-1-phenil-1H-pyrazole-3il)phenol (TFP-2OH-4Cl) was synthesized via oxidative aromatization reaction of pyrazoline 2-(5-(4-chlorophenil)-1-phenil-4,5-dihydro-1H-pyrazole-3-il)phenol (PF-2OH-4Cl) with glacial acetic acid. Chalcone, pyrazoline, and pyrazole were synthesized using the microwave at 180 W at 85oC. The purity of the compounds was monitored on TLC plates, melting point, and HPLC analysis. The structure of synthesized compounds was confirmed by UV, FTIR, …

Improving The Quality Of Micronutrient Food Composition Data In Sub-Saharan Africa Using Predictive Analytics, Junior Mbuyamba Muka
Theses and Dissertations
High-quality food composition data are indispensable for decision making in several health, agricultural, and nutrition-related activities. Analytical data are the most accurate type of food composition data (FCD). Yet, most food composition databases (FCDBs) compiled in Sub-Saharan Africa only contain a small amount of analytical data collected from foods consumed in this region. Most of the data are either borrowed / copied from FCDBs collected in other parts of the world, calculated, imputed, or presumed data. Even with these alternative types, FCDBs in Sub-Saharan Africa have not reached a satisfactory level of completeness, as they still have missing data for …

Perbandingan Kadar Magnesium Pada Air Minum Dalam Kemasan (Amdk) Menggunakan Metode Spektrofotometri Dan Kompleksometri, Edy Agustian Yazid, Abdul Wafi, Roihatul Zahroh, Nurul Azizah
Chimica et Natura Acta
Magnesium (Mg) merupakan salah satu mineral penting dalam tubuh yang memiliki fungsi memelihara kesehatan jantung, tulang, mengatur kadar gula darah hingga membantu mengatasi stres. Kebutuhan magnesium diantaranya dapat dipenuhi melalui Air Minum Dalam Kemasan (AMDK). Tujuan penelitian ini adalah untuk mengetahui perbedaaan kadar magnesium pada AMDK menggunakan metode spektrofotometri dan kompleksometri. Melalui perbandingan kedua metode tersebut dapat diketahui aplikasi metode yang lebih praktis dan efisien. Penentuan magnesium secara spektrofotometri dilakukan dengan mengukur terbentuknya senyawa kompleks Mg-EBT menggunakan spektrofotometer visibel pada panjang gelombang maksimum 530 nm. Hasil penelitian kadar magnesium pada AMDK metode spektrofotometri didapatkan kadar antara 1,5-19,45 mg/L, sedangkan dengan …

Standardized approaches to phage susceptibility testing (PST) are essential to inform selection of phages for study in patients with bacterial infections. There is no reference standard for assessing bacterial susceptibility to phage. We compared agreement between PST performed at three centers: two centers using a liquid assay standardized between the sites with the third, a plaque assay. Four Pseudomonas aeruginosa phages: PaWRA01ø11 (EPa11), PaWRA01ø39 (EPa39), PaWRA02ø83 (EPa83), PaWRA02ø87 (EPa87), and a cocktail of all four phages were tested against 145 P. aeruginosa isolates. Comparisons were made within measurements at the two sites performing the liquid assay and between these …

To escape from dangerous stimuli, animals execute escape behaviors that are fundamentally different from normal locomotion. The rolling escape behavior of Drosophila larvae consists of C-shaped bending and rolling. However, the muscle contraction patterns that lead to rolling are poorly understood. We find that following the initial body bending, muscles contract in a circumferential wave around the larva as they enter the bend, maintaining unidirectional rolling that resembles a cylinder rolling on a surface. We study the structure of motor circuits for rolling, inhibit different motor neurons to determine which muscles are essential for rolling, and propose circuit and biomechanical …
