Over-Policing And Under-Protecting In American Cities, Margaret Hession Dec 2022

Over-Policing And Under-Protecting In American Cities, Margaret Hession

Honors Program Theses and Projects

In recent years there have been numerous protests all over the United States focused on the over-policing of African Americans by law enforcement. Those involved are protesting against a term known as over-policing, the blatant brutality and senseless murders, that have taken place for decades but have been made ever more visible by our modern media channels. “Over-policing allows police to use excessive force and brutalize disenfranchised neighborhoods and target people of color indiscriminately. Ironically, as politicians take a “tough on crime” stance, violence has actually gone down, but police budgets and presence have increased. The American criminal justice system …

Preventing Chlorogenic Acid Quinone-Induced Greening In Sunflower Cookies By Chlorogenic Acid Esterase And Thiol-Based Dough Conditioners, Nana Baah Pepra-Ameyaw, Christine Lo Verde, Charles T. Drucker, Cedric P. Owens, Lilian W. Senger

Food Science Faculty Articles and Research

Sunflower seeds contain a high concentration of chlorogenic acid (CGA), which reacts with amino acids to form green pigments under alkaline conditions during food processing. Here, we present two approaches to prevent green pigment formation in sunflower cookies by (A) Addition of free thiols from cysteine and glutathione to sunflower cookie dough and (B) hydrolyzing CGA into caffeic acid and quinic acid with a CGA esterase from Lactobacillus helveticus. Greening occurred more slowly with cysteine; however, neither cysteine nor glutathione prevented greening in the cookies during storage. Chlorogenic acid esterase hydrolyzed CGA in both sunflower butter and flour, resulting …

Making Group Work Work: Constructing Groups And Assignments Based Around Relevant Assessments To Increase Student Success, James Altman

UNLV Best Teaching Practices Expo

Helping college students get the most out of their talents, is challenging even without the ongoing uncertainty of the post-Pandemic landscape. Shyness, lack of comfort with the subject matter, and fear of having their ideas dismissed, can all keep students from expressing their ideas as fully as they, and we, would like. This can lead to non-completion or plagiarism of assignments. In group settings, it can lead to one student “taking over” the project, or the rest of the group “pushing it off” on one member. Constructing groups and/or assignments based around relevant assessments, namely Myers-Briggs and “The Six Working …
