Predicting Different Psychological Profiles Amongst Substance Users., Zach J. Gray
Graduate Theses and Dissertations
Substance use disorders (SUDs) are some of the most prevalent issues facing society. As SUDs are highly individualized in how they manifest, recent work has attempted to classify distinct profiles of drug users to better understand what factors put someone at risk for shifting from casual substance use to developing a substance use disorder (SUD). Common risk factors for SUD development include stressor exposure, difficulties with emotion regulation, personality, and risky decision-making. As many of the behaviors that constitute SUDs are exhibited prior to potential diagnosis, developing “profiles” that combine these traits and experiences could eventually predict SUDs. The current …

Supervenience And Non-Naturalism, Michael Hogan
Supervenience And Non-Naturalism, Michael Hogan
Graduate Theses and Dissertations
Supervenience presents a problem for the moral non-naturalist. Supervenience states that one’s moral properties cannot differ without one’s natural properties differing. It, therefore, states a necessary connection between moral and natural properties. Moral properties for the moral non-naturalist are sui generis, which means they are not reducible to natural properties, but also they are utterly different in kind than natural properties and any other kind of property. How can these properties be necessarily connected? This requires an explanation. The challenge to the moral non-naturalist is to provide such an explanation. McPherson (2012) presents an explanatory challenge to the non-naturalist …
