The mentally retarded offender in the state prison system: identification, prevalence, adjustment, and rehabilitation

Abstract: This study established a current average national estimate of the prevalence of mental retardation among state prison inmates, and gathered information regarding their adjustment to incarceration and rehabilitative services provided them. It was determined that an average of 2% or about 7,600 inmates are mentally retarded, and that the number presently confined in all types of correctional settings is approximately 12,640. That relatively low figure was attributed to the emergence of various diversion processes and improved psychometric practice, and it was expected that these ongoing trends would reduce this prevalence rate even further in the future. It was also concluded that the mentally retarded do not adjust well to prison life, and that the mentally retarded do not adjust well to prison life, and that supplemental rehabilitation services for them at those sites had not expanded appreciably over the past two decades.

APOGEE KINEMATICS. I. OVERVIEW of the KINEMATICS of the GALACTIC BULGE AS MAPPED by APOGEE

Abstract: We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky Way. APOGEE includes extensive coverage of the stellar populations of the bulge along the mid-plane and near-plane regions. From these data, we have produced kinematic maps of 10,000 stars across longitudes 0 deg -0.5 have dispersion and rotation profiles that are similar to that of N-body models of boxy/peanut bulges. There is a smooth kinematic transition from the thin bar and boxy bulge (l,|b|) -1.0, and the chemodynamics across (l,b) suggests the stars in the inner Galaxy with [Fe/H] > -1.0 have an origin in the disk.

Short Sale Constraints, Overvaluation, and the Introduction of Options

Abstract: We investigate whether the existence of traded options represents an economically important relaxation of short sale constraints Our analysis has three prongs First, to the extent that option listing relaxes a binding constraint, we would expect to see investors taking synthetic short positions in the newly-listed options Contrary to this hypothesis, we find that the volume of newly-listed options tends to be very low, and, if anything, signed volume is more bullish that bearish during the first week of trading Moreover, we find no significant relation between signed option volume and abnormal stock returns surrounding option listing Second, if options help relax binding short-sale constraints, we might expect bearish option volume to be positively related to proxies for short sale constraints, divergence of opinion, and/or overvaluation We examine nine different proxies and combinations of proxies, and in each case find either no relation, or a significant negative relation Third, we demonstrate that prior results in the literature reporting a negative price reaction surrounding option listing are not robust to alternative methodological assumptions All our evidence suggests that options do not reduce short sale constraints in an economically meaningful way

Measuring CEO personality: Developing, validating, and testing a linguistic tool

Abstract: Research Summary We introduce to the upper echelons literature a novel, linguistic measure of CEOs' Big Five personality traits that we specifically developed and validated using a sample of CEOs. We then provide a predictive test of the measure by applying it to a sample of more than 3,000 CEOs of S&P 1500 firms to explore the direct and interactive effects of CEOs' Big Five personality traits and firm performance on strategic change. Our validated, unobtrusive measure of CEOs' Big Five traits provides a strong foundation for future theory development on the firm‐level effects of CEOs' personality traits. Our specific findings also extend our understanding of how CEO personality influences firm‐level change and how both person and situation‐based factors interact to jointly influence firm strategy. Managerial Summary This paper introduces a language‐based tool we developed to measure the Big Five personality traits (i.e., openness, conscientiousness, extraversion, agreeableness, and neuroticism) of more than 3,000 CEOs of S&P 1500 firms. After describing our process to develop and validate the tool, we test it by examining how CEOs' Big Five traits influence strategic change, both in isolation and in combination with recent firm performance. Our results suggest that CEOs' personality traits have a meaningful impact on strategic change, but that the nature of these effects differs based on their firms' recent performance. Our tool also provides a strong basis for scholars seeking to measure the personality traits of large samples of public‐company executives.
