Dual-process theory of racial isolation, legal cynicism, and reported crime.

ABSTRACT: Why is neighborhood racial composition linked so strongly to police-reported crime? Common explanations include over-policing and negative interactions with police, but police reports of crime are heavily dependent on resident 911 calls. Using Sampson's concept of legal cynicism and Vaisey's dual-process theory, we theorize that racial concentration and isolation consciously and nonconsciously influence neighborhood variation in 911 calls for protection and prevention. The data we analyze are consistent with this thesis. Independent of police reports of crime, we find that neighborhood racial segregation in 1990 and the legal cynicism about crime prevention and protection it engenders have lasting effects on 911 calls more than a decade later, in 2006-2008. Our theory explains this persistent predictive influence through continuity and change in intervening factors. A source of cumulative continuity, the intensification of neighborhood racial concentration and isolation between 1990 and 2000, predicts 911 calls. Likewise, sources of change-heightened neighborhood incarceration and home foreclosures during the financial crisis in 2006-2008-also predict these calls. Our findings are consistent with legal cynicism theory's focus on neighborhood disadvantage, racial isolation, and concerns about police protection and crime prevention; they correspond less with the emphasis of procedural justice theory on police legitimacy.

Project description:The brain requires continuously high energy production to maintain ion gradients and normal function. Mitochondria critically undergird brain energetics, and mitochondrial abnormalities feature prominently in neuropsychiatric disease. However, many unique aspects of brain mitochondria composition and function are poorly understood. Developing improved neuroprotective therapeutics thus requires more comprehensively understanding brain mitochondria, including accurately delineating protein composition and channel-transporter functional networks. However, obtaining pure mitochondria from the brain is especially challenging due to its distinctive lipid and cell structure properties. As a result, conflicting reports on protein localization to brain mitochondria abound. Here we illustrate this problem with the neuropsychiatric disease-associated L-type calcium channel Cav1.2α1 subunit previously observed in crude mitochondria. We applied a dual-process approach to obtain functionally intact versus compositionally pure brain mitochondria. One branch utilizes discontinuous density gradient centrifugation to isolate semipure mitochondria suitable for functional assays but unsuitable for protein localization because of endoplasmic reticulum (ER) contamination. The other branch utilizes self-forming density gradient ultracentrifugation to remove ER and yield ultrapure mitochondria that are suitable for investigating protein localization but functionally compromised. Through this process, we evaluated brain mitochondria protein content and observed the absence of Cav1.2α1 and other previously reported mitochondrial proteins, including the NMDA receptor, ryanodine receptor 1, monocarboxylate transporter 1, excitatory amino acid transporter 1, and glyceraldehyde 3-phosphate dehydrogenase. Conversely, we confirmed mitochondrial localization of several plasma membrane proteins previously reported to also localize to mitochondria. We expect this dual-process isolation procedure will enhance understanding of brain mitochondria in both health and disease.
