Policing Understood As A Racial Project: An Exploration Of The Role Law Enforcement Has Played In The Shaping Of Race Relations In The United States, Jahaan Chandler

LSU Doctoral Dissertations

Law enforcement and minority communities have had a complicated history in the United States to say the least. The theoretical propositions used to explain the myriad of interlocking relationships between race, criminal activity, neighborhood disorder, public perceptions of crime, and law enforcement itself, have provided us with nuggets of insight that have all contributed to enhancing our understanding of crime and policing in the U.S., but none have provided an overall interpretation of this complex and often convoluted relationship. This dissertation seeks to rectify this issue by not only examining the history of law enforcement and its relation to minority …

Southwest Pacific Tropical Cyclone Frequency And Intensity Related To Observed And Modeled Geophysical And Aerosol Variables, Rupsa Bhowmick

LSU Doctoral Dissertations

The dissertation focuses on western region of Southwest Pacific Ocean (SWPO)

basin (135E - 180, and 5S - 35S) tropical cyclone (TC) climatology using observed

and modeled data. The classification-based machine learning approach

identifies the synoptic geophysical and aerosol environment favorable or unfavorable

for TC intensification and intensity change prior to landfall incorporating

observational and satellite data. A multiple poisson regression model with varying

temporal monthly lags was used to build a relationship between the number of

monthly TC days with basin wide average dust aerosol optical depth (AOD), sea

surface temperature (SST), and upper ocean temperature (UOT). This idea …

Teaching Introductory Statistics To Graduate Students In The Social Sciences: A Mixed Method Investigation Of The Effectiveness Of Simulations In Statistics Education, Liuli Huang

LSU Doctoral Dissertations

The primary purpose of this study is to determine the effectiveness of using simulations as an instructional tool in an introductory doctoral level statistics course. The study focuses on the impacts of simulations on students’ attitudes and understanding of statistical concepts, as well as how the simulations could inspire students’ positive attitudes and improve statistics performance or would fail to help. In addition, since the statistics anxiety has been a primary obstacle to students’ statistics education, and “statistics anxiety” is experienced by as many as 80% of graduate students (Onwuegbuzie, 2004). The researcher is interested to explore the details of …
