Virtual reality cue reactivity assessment in cigarette smokers.

Drug craving has purportedly been linked to relapse and to substance use. For over two decades, cue reactivity has been a viable method to assess craving and physiological reactions to drug stimuli. However, traditional cue reactivity has faced the following limitations: austere situations or stimuli, lack of complex cues, lack of standardization, and limited generalization outside of the lab setting. In order to improve cue methodologies, a virtual reality (VR) nicotine cue reactivity assessment system (VR-NCRAS) was developed and tested in a controlled experimental trial. Ten nicotine dependent smokers were exposed to VR smoking cues and VR neutral cues in a standardized, timed, computer controlled experiment. Subjective craving and physiological responses were recorded and compared across VR-NCRAS stimuli. Subjective cigarette craving increased significantly and corresponding physiological reactivity was observed in response to VR smoking cues. VR neutral cues did not result in subjective or physiological changes consistent with craving. Implications of these findings on substance abuse research and treatment are discussed.

Evaluating wraparound services for seriously emotionally disturbed youth: pilot study outcomes in Georgia

Since the early 1990s, intervention strategies designed to preserve the family system while serving children diagnosed with severe emotional disturbances (SED) have been on the rise. Many of these strategies sought to provide families with comprehensive approaches that link various agencies and services, thus providing a complete system of care. The term wraparound services was coined to describe these approaches. However, evaluation studies of the outcomes of these programs remains limited. In order to assess the impact of wraparound services, outcome evaluation programs need to be implemented and their feasibility assessed. This paper focuses on the feasibility and implementation of a computer-based field assessment system and the ability to provide empirically based feedback to the programs. In addition, an assessment of 15 participating children and families, comparing selected aspects of clinical functioning at intake and 6-month follow-up, is presented and discussed.     

International Law and Morality in the Theory of Secession

In order responsibly to decide whether there ought to be an international legal right of secession, I believe we need an account of the morality of secession. I propose that territorial and political societies have a moral right to secede, and on that basis I propose a regime designed to give such groups an international legal right to secede. This regime would create a procedure that could be followed by groups desiring to secede or by states desiring to resolve the issue of secession. It would give territorial political societies a legally recognized liberty to conduct a plebiscite on secession, and, assuming such a plebiscite is won by the secessionist side, a qualified right in international law to create a state without interference. Alan Buchanan has argued that proposals of this sort would create perverse incentives. I argue that there is no good reason to believe this. The point is to allow the legal regulation of secession in cases where there are active secessionist movements with legitimate moral claims, and to attempt to dampen the desire for secession in cases where secessionist sentiment is not well grounded in social and geographic reality.
