Drug Ideologies Of The United States, Macy Montgomery
Helm's School of Government Conference - American Revival: Citizenship & Virtue
The United States has been increasingly creating lenient drug policies. Seventeen states and Washington, the District of Columbia, legalized marijuana, and Oregon decriminalized certain drugs, including methamphetamine, heroin, and cocaine. The medical community has proven that drugs, including marijuana, have myriad adverse health side effects. This leads to two questions: Why does the United States government continue to create lenient drug policies, and what reasons do citizens give for legalizing drugs when the medical community has proven them harmful? The paper hypothesizes that the disadvantages of drug legalization outweigh its benefits because of the numerous harms it causes, such as …

Role Of Salinity In Perfluorooctane Sulfonate (Pfos) Bioconcentration Between Aquatic Species And The Differential Regulation Of Transporters In Fundulus Heteroclitus, Tyler Davis
All Theses
Perfluorooctane sulfonate (PFOS) is a persistent organic pollutant that is known for its surfactant properties and its resistance to degradation. The persistence and lipophilicity of PFOS in surface waters have led to its bioaccumulation in fish, which in turn leads to its accumulation and toxic effects in humans that consume fish. PFOS is also hypothesized to perturb reproduction and survival of low and mid-trophic level zooplankton species such as Daphnia magna that are food for multiple fish species. In this study, a 21-day D. magna chronic toxicity test was performed using 1,10, 100, 1000, and 5000 ppb of PFOS to …
