“They hate me now but where was everyone when I needed them?”: Mass incarceration,projective identification,and social work praxis

Mass incarceration has been thoroughly explored as a racial, social, and economic project. A psychoanalytic lens makes visible another dimension: the ways in which the dehumanization and criminalization of certain members of society forces them to function as repositories for the unbearable aspects of our otherwise shared humanity. In this article, I take a psychodynamic social work perspective and explore how the creation and maintenance of traumatogenic conditions, and the criminalization of the adaptations that people make to them, enables the logic of mass incarceration by taking a problem in the environment—one that implicates the collective—and relocates it inside the individual—as a person to be punished. Applying the concept of projective identification to these social-level dynamics, I argue that mass incarceration serves an important psychological function for society related to anxieties about racial and economic inequality and, as such, we continue to invest in mass incarceration despite its failure. I discuss its implications for social work praxis, emphasizing the need for both meaningful thought and effective action. I take an interdisciplinary approach and rely on psychoanalysis, sociology, criminology, and critical race studies in the hope of making clear the pernicious hold that mass incarceration has on the United States, and the work we must do as a collective to wrest ourselves from it.     

Density evolution during the growth of disc-shaped aluminium nanoparticles on a liquid surface

Aluminium (Al) nanoparticles (NPs) have been successfully fabricated on a liquid surface by thermal evaporation at room temperature. The Al NPs exhibit a disc-shaped morphology with mean diameter and height in the ranges 20–35 and 1.3–3.7?nm, respectively. As the nominal film thickness increases from 0.02 to 0.18?nm, the mean diameter and height are nearly independent of the thickness, implying that the density of the NPs increases during their growth. An explanation for this phenomenon is presented.     

Posture-movement responses to stance perturbations and upper limb fatigue during a repetitive pointing task

Localized muscle fatigue and postural perturbation have separately been shown to alter whole-body movement but little is known about how humans respond when subjected to both factors combined. Here we sought to quantify the kinematics of postural control and repetitive upper limb movement during standing surface perturbations and in the presence of fatigue. Subjects stood on a motion-based platform and repetitively reached between two shoulder-height targets until noticeably fatigued (rating of perceived exertion = 8/10). Every minute, subjects experienced a posterior and an anterior platform translation while reaching to the distal target. Outcomes were compared prior to and with fatigue (first vs. final minute data). When fatigued, regardless of the perturbation condition, subjects decreased their shoulder abduction and increased contralateral trunk flexion, a strategy that may relieve the load on the fatiguing upper limb musculature. During perturbations, kinematic adaptations emerged across the trunk and arm to preserve task performance. In contrast to our expectation, the kinematic response to the perturbations did not alter in the presence of fatigue. Kinematic adaptations in response to the perturbation predominantly occurred in the direction of the reach whereas fatigue adaptations occurred orthogonal to the reach. These findings suggest that during repetitive reaching, fatigue and postural perturbation compensations organize so as to minimize interaction with each other and preserve the global task characteristics of endpoint motion.
