Dignifying Madness: Rethinking Commitment Law in an Age of Mass Incarceration

Modern nation-states have been trapped in recurring cycles of incarcerating and emancipating residents with psychiatric disabilities. New cycles of enthusiasm for incarceration generally commence with well-defined claims about the evils of allowing “the mad” to remain at liberty and the benefits incarceration would bring to the afflicted. A generation or two later, at most, reports of terrible conditions in institutions circulate and new laws follow, setting high burdens for those seeking to imprison and demanding exacting legal procedures with an emphasis on individual civil liberties. Today, we seem to be arriving at another turn in the familiar cycle. A growing movement led by professionals and family members of people with mental health disabilities is calling for new laws enabling earlier and more assertive treatment. After reviewing the history of civil commitment law, this essay suggests that the time is ripe in the United States to end this recurring cycle and make conservation of human dignity the core legal authority behind the state’s power of civil commitment and the major normative guide for both legal procedure and treatment. We conclude that the dignity approach has the potential to move the debate beyond the current face-off between consumer and peer advocates, who wish to avoid any revision of the civil commitment reforms enacted forty years ago, and families and professionals, who favor significant changes

The stability of a crystal with diamond structure for patchy particles with tetrahedral symmetry

The phase diagram of model anisotropic particles with four attractive patches in a tetrahedral arrangement has been computed at two different values for the range of the potential, with the aim of investigating the conditions under which a diamond crystal can be formed. We find that the diamond phase is never stable for our longer-ranged potential. At low temperatures and pressures, the fluid freezes into a body-centred-cubic solid that can be viewed as two interpenetrating diamond lattices with a weak interaction between the two sublattices. Upon compression, an orientationally ordered face-centred-cubic crystal becomes more stable than the body-centred-cubic crystal, and at higher temperatures a plastic face-centered-cubic phase is stabilized by the increased entropy due to orientational disorder. A similar phase diagram is found for the shorter-ranged potential, but at low temperatures and pressures, we also find a region over which the diamond phase is thermodynamically favored over the body-centred-cubic phase. The higher vibrational entropy of the diamond structure with respect to the body-centred-cubic solid explains why it is stable even though the enthalpy of the latter phase is lower. Some preliminary studies on the growth of the diamond structure starting from a crystal seed were performed. Even though the diamond phase is never thermodynamically stable for the longer-ranged model, direct coexistence simulations of the interface between the fluid and the body-centred-cubic crystal and between the fluid and the diamond crystal show that, at sufficiently low pressures, it is quite probable that in both cases the solid grows into a diamond crystal, albeit involving some defects. These results highlight the importance of kinetic effects in the formation of diamond crystals in systems of patchy particles.Comment: 15 pages, 13 figure

Neural activity during a simple reaching task in macaques is counter to gating and rebound in basal ganglia–thalamic communication

Task-related activity in the ventral thalamus, a major target of basal ganglia output, is often assumed to be permitted or triggered by changes in basal ganglia activity through gating- or rebound-like mechanisms. To test those hypotheses, we sampled single-unit activity from connected basal ganglia output and thalamic nuclei (globus pallidus-internus [GPi] and ventrolateral anterior nucleus [VLa]) in monkeys performing a reaching task. Rate increases were the most common peri-movement change in both nuclei. Moreover, peri-movement changes generally began earlier in VLa than in GPi. Simultaneously recorded GPi-VLa pairs rarely showed short-time-scale spike-to-spike correlations or slow across-trials covariations, and both were equally positive and negative. Finally, spontaneous GPi bursts and pauses were both followed by small, slow reductions in VLa rate. These results appear incompatible with standard gating and rebound models. Still, gating or rebound may be possible in other physiological situations: simulations show how GPi-VLa communication can scale with GPi synchrony and GPi-to-VLa convergence, illuminating how synchrony of basal ganglia output during motor learning or in pathological conditions may render this pathway effective. Thus, in the healthy state, basal ganglia-thalamic communication during learned movement is more subtle than expected, with changes in firing rates possibly being dominated by a common external source
