ABSTRACT
Substance use disorder (SUD) is common among victims of sex trafficking. Traffickers may exploit individuals' existing opioid use or other SUDs to coerce them into sex trafficking, or they may facilitate substance use to keep trafficking victims from exiting. Additionally, trafficking victims may use substances to cope with trauma. The intersections of sex trafficking and SUD complicate both legal responses and victim advocate responses to sex trafficking cases. Victim SUD can lead to challenges for law enforcement and prosecutors in developing cases against traffickers. On the provider side, traditional victim services are often insufficient for victims of trafficking with SUDs, who face substantial barriers to accessing services. A better understanding of the nexus between sex trafficking and SUDs is critical for implementing victim-centered and trauma-informed responses to this vulnerable population. In this article, the authors describe an online panel, convened in April 2021 by RTI International and the RAND Corporation on behalf of the National Institute of Justice, in which subject-matter experts and criminal justice practitioners discussed how SUDs and sex trafficking complicate the identification and screening of victims and victims' ability to access treatment and legal remedies. The panel participants identified 21 high-priority needs to support a better understanding of sex trafficking and SUDs and a variety of solutions for addressing these intertwined issues.
ABSTRACT
Both the adsorption of t-butylpyridine and the atomic-layer deposition of ultrathin conformal coatings of insulators (such as alumina) are known to boost open-circuit photovoltages substantially for dye-sensitized solar cells. One attractive interpretation is that these modifiers significantly shift the conduction-edge energy of the electrode, thereby shifting the onset potential for dark current arising from the interception of injected electrons by solution-phase redox shuttle components such as Co(phenanthroline)(3)(3+) and triiodide. For standard, high-area, nanoporous photoelectrodes, band-edge energies are difficult to measure directly. In contrast, for flat electrodes they are readily accessible from Mott-Schottky analyses of impedance data. Using such electrodes (specifically TiO(2)), we find that neither organic nor inorganic electrode-surface modifiers shift the conduction-band-edge energy sufficiently to account fully for the beneficial effects on electrode behavior (i.e., the suppression of dark current). Additional experiments reveal that the efficacy of ultrathin coatings of Al(2)O(3) arises chiefly from the passivation of redox-catalytic surface states. In contrast, adsorbed t-butylpyridine appears to suppress dark currents mainly by physically blocking access of shuttle molecules to the electrode surface. Studies with other derivatives of pyridine, including sterically and/or electronically diverse derivatives, show that heterocycle adsorption and the concomitant suppression of dark current does not require the coordination of surface Ti(IV) or Al(III) atoms. Notably, the favorable (i.e., negative) shifts in onset potential for the flow of dark current engendered by organic and inorganic surface modifiers are additive. Furthermore, they appear to be largely insensitive to the identity of shuttle molecules.
