Restraint and Seclusion of Students With a Disability Continue to Be Common in Some School Districts Patterns Remain Relatively Consistent Despite Recent Policy Changes

In 2013, Carsey released a brief that analyzed rates of restraint and seclusion using a large, nationally representative data set of U.S. school districts. This brief, which analyzes a more comprehensive data set and the most current Civil Rights Data Collection, serves as a follow-up to the pre­vious brief. Authors Douglas Gagnon, Marybeth Mattingly, and Vincent Connelly report that, despite numerous states with revised policies related to seclusion and restraint in schools between 2009 and 2012, trends in the rates of restraint and seclusion of students with a disability in the United States remained relatively consistent between survey years. Low-poverty, low-minority districts are more likely to report high rates of restraint than are high-poverty, high-minority districts, although this trend in the most recent data is less pronounced than the trend found in the 2009−2010 data. In addition, restraint and seclusion are most common in cities and least common in rural places. The authors conclude that future research should examine the factors that lead to the use of restraint and seclusion in some schools, as well as what conditions lead to uptake of alternative approaches to managing challenging student behavior

Variation found in rates of restraint and seclusion among students with a disability

The restraint and seclusion of individuals—practices usually associated with highly restrictive environments—are extreme responses to student behavior used in some public schools. In this brief, authors Douglas Gagnon, Marybeth Mattingly, and Vincent Connelly report that restraint and seclusion are used much more frequently on students with a disability than on students without a disability. In addition, the majority of U.S. school districts does not restrain or seclude students with a disability; 59.3 percent of districts report no instances of restraint, while 82.5 percent do not report a single instance of seclusion. However, a small proportion of districts report exceedingly high rates. The authors also find that low-poverty, low-diversity school districts use restraint and seclusion on students with a disability more than twice as often as high-poverty, high-diversity districts. The authors conclude that, overall, the relationships between restraint and seclusion rates, and disability type and school characteristics, warrant further research. This brief draws on data from the 2009–2010 Civil Rights Data Collection and the 2009 Small Area Income and Poverty Estimates

W. Org. Res. Councils, et al. v. U.S. Bureau of Land Mgmt.

The United States District Court for the District of Montana granted Plaintiffs summary judgment against BLM and the State of Wyoming. The court ruled that BLM violated NEPA and the APA because it failed to consider alternative leasing programs and the broad downstream impacts of coal, oil, and gas leasing in two Powder River Basin resource management plans. This decision followed WORC I & II, in which the court remanded the same plans to BLM to correct deficiencies. Following BLM’s revisions, Plaintiffs again sued in this case, arguing the revisions were still deficient under NEPA

Asteroid lightcurve inversion

One of the most fundamental physical properties of any asteroid is its shape. Lightcurves provide the only source of shape information for most asteroids. Unfortunately, the functional form of a lightcurve is determined by the viewing/illumination geometry and the asteroid's light scattering characteristics as well as its shape, and in general it is impossible to determine an asteroid's shape from lightcurves. A technique called convex-profile inversion (CPI) that obtains a convex profile, P, from any lightcurve is introduced. If certain ideal conditions are satisfied, then P is an estimator for the asteroid's mean cross section, C, a convex set defined as the average of all cross sections C(z) cut by planes a distance z above the asteroids's equatorial plane. C is therefore a 2-D average of the asteroid's 3-D shape
