The Development And Optimization Of A Two-Dimensional Lc-Qqq-Ms-Method For The Combined Analysis Of Synthetic Cannabinoids And Designer Cathinones In Urine, Holly Penefsky

Electronic Theses and Dissertations

The compounds and chemical compositions of synthetic cannabinoids and designer cathinones are designed to mimic the intoxicating effects of D⁹-tetrahydrocannabinol and amphetamines, respectively. In order to skirt existing drug laws, non-controlled ingredients are used, and the original chemical structures of current drugs are being modified using analogs or derivatives. These continually changing chemical compositions pose a problem for policymakers, and forensic and analytical scientists, as users are able to attain a “legal high” and avoid detection in standard drug screens. Commonly, toxicology laboratories utilize a screening method, such as immunoassay, for the presumptive identification of designer drugs. When …

School Choice Considerations Of Black Parents Of Students With Dis/Abilities, Jaleah Robinson

Electronic Theses and Dissertations

Forty-four states and Washington, D.C. have passed legislation to expand school choice options for students and families (Cardine, 2019). In addition to a student’s assigned neighborhood school, one may enact choice by way of tax credits, charter schools, vouchers, relocation, and through other means, depending on where one lives. The act of choosing a school has been simplified by some to economic principles of competition and consumer satisfaction. What research has shown, however, is enacting school choice is much more complex and commonly intertwined with concepts of race, class, and ability (Ellison & Aloe, 2019). Academic quality (Mavrogordato & Stein, …

Implicit Theories As A Moderator Between Religious Commitment And Forgiveness Among Muslims Experiencing A Religious Identity Offense., John Michael Hart Ii

Electronic Theses and Dissertations

A recurrent finding in the literature on the relationship between religion and forgiveness is that religious people tend to describe themselves as forgiving while reporting less forgiveness in response to actual offenses (Davis, Worthington, Hook, & Hill, 2013; McCullough & Worthington, 1999). Scholars have suggested moderating factors may explain this discrepancy (Worthington et al., 2010), though the existing literature has been criticized as limited because much of the research is based on Christian samples (Carlisle & Tsang, 2013; Davis et al., 2013). Implicit theories, which have previously been found to be associated with forgiveness and theorized to be related to …
