Type 2 Diabetes Mellitus (T2dm) Onset And "Remission"., Srikanth Tangelloju

Electronic Theses and Dissertations

Background: Type 2 diabetes mellitus (T2DM) is a progressive disease condition. As the disease progresses the function of beta (β) cells (cells which regulate insulin) decline, thereby increasing the circulating blood glucose levels. If left unmanaged the disease progresses from onset to development of T2DM related complications and eventually death. When managed, in certain individuals, T2DM onset can be prevented and/or slowed down and in certain T2DM individuals, remission is observed. There are some known modifiable risk factors such as diet and physical activities that are associated with the speed and direction of progression, but much is still unknown. In …

The Stigma Effect: The Role Of Internalized Racism And Internalized Homophobia In Risky Sexual Behavior Among Black Gay Men, Darren Lovell Whitfield Jan 2016

The Stigma Effect: The Role Of Internalized Racism And Internalized Homophobia In Risky Sexual Behavior Among Black Gay Men, Darren Lovell Whitfield

Electronic Theses and Dissertations

Black gay, bisexual, queer, and same-gender-loving (GBQSGL) men account for less than 1% of US population, yet account for 36% of all new HIV infections. While, Black GBQSGL men experience higher rates of HIV infection compared to other gay, bisexual, and men who have sex with men (MSM) from other racial groups, they are no more likely to report engaging in condomless anal sex (CAS). These findings suggest that one possible explanation is that the context of sexual behavior for Black GBQSGL men may be riskier because of the prevalence of HIV in the community. Furthermore, research suggests that racism …

Improving The Inference Of Some Experiemtal Studies By Using Ranked Auxiliary Covariates, Rajai Jabrah Jan 2016

Improving The Inference Of Some Experiemtal Studies By Using Ranked Auxiliary Covariates, Rajai Jabrah

Electronic Theses and Dissertations

In many studies, the measurement of sampling units according to the response variable is costly or time consuming, however, it is possible to rank sampling units according to baseline auxiliary covariates, which are available, easily obtainable, and cost efficient. In these cases, when estimating the population mean, Ranked Set Sampling (RSS) can be a more efficient sampling method than the Simple Random Sampling (SRS) method. In this dissertation, we propose a modified approach of the RSS method to allocate units into an experimental study, aimed to compare two or more groups.

Ranked auxiliary covariates, which are typically correlated with the …
