Giving Voice to the Voiceless

The purpose of this study is to understand the experiences of matriculated, full time college students from a medium-sized Catholic, Liberal Arts College in the Northeast who identify as multi-racial or multi-ethnic, specifically identifying as coming from a white and non-white mixed background. In the ever-changing political climate in the United States, those who identify as mixed white and non-white backgrounds feel conflicted in how they ethnically or racially identify. Emerging adulthood (ages 18-25), and college experiences, are important years for identity development. This study tells the untold narratives of mixed non-white and white multi-racial, multi-ethnic individuals

Have Recent Budget Policies Contributed to Long-Run Fiscal Stability?

Examines developments in budget policies since January 2010; the president's 2011 budget, including economic stimulus and tax and spending policies; congressional action; and issues for health reform. Considers their effect on long-term sustainability

Committees Tackle the Deficit

Summarizes the recommendations of a presidential commission and private bipartisan committee for reducing the federal deficit by cutting healthcare costs, Social Security outlays, and discretionary spending, and by raising taxes

Controlling the Deficit: The Debate Continues

Looks at budget cuts proposed by House Republicans and the president's framework with respect to savings in healthcare spending, Social Security and other entitlement spending, and discretionary spending; tax policy; and the Budget Control Act

Edge-region grouping in figure-ground organization and depth perception.

Edge-region grouping (ERG) is proposed as a unifying and previously unrecognized class of relational information that influences figure-ground organization and perceived depth across an edge. ERG occurs when the edge between two regions is differentially grouped with one region based on classic principles of similarity grouping. The ERG hypothesis predicts that the grouped side will tend to be perceived as the closer, figural region. Six experiments are reported that test the predictions of the ERG hypothesis for 6 similarity-based factors: common fate, blur similarity, color similarity, orientation similarity, proximity, and flicker synchrony. All 6 factors produce the predicted effects, although to different degrees. In a 7th experiment, the strengths of these figural/depth effects were found to correlate highly with the strength of explicit grouping ratings of the same visual displays. The relations of ERG to prior results in the literature are discussed, and possible reasons for ERG-based figural/depth effects are considered. We argue that grouping processes mediate at least some of the effects we report here, although ecological explanations are also likely to be relevant in the majority of cases

The narrative coherence of witness transcripts in children on the autism spectrum

Background and Aims. Autistic children often recall fewer details about witnessed events than typically developing children (of comparable age and ability), although the information they recall is generally no less accurate. Previous research has not examined the narrative coherence of such accounts, despite higher quality narratives potentially being perceived more favourably by criminal justice professionals and juries. This study compared the narrative coherence of witness transcripts produced by autistic and typically developing (TD) children (ages 6-11 years, IQs 70+). Methods and Procedures. Secondary analysis was carried out on interview transcripts from a subset of 104 participants (autism=52, TD=52) who had taken part in a larger study of eyewitness skills in autistic and TD children. Groups were matched on chronological age, IQ and receptive language ability. Coding frameworks were adopted from existing narrative research, featuring elements of ‘story grammar’. Outcomes and Results. Whilst fewer event details were reported by autistic children, there were no group differences in narrative coherence (number and diversity of ‘story grammar’ elements used), narrative length or semantic diversity. Conclusions and Implications. These findings suggest that the narrative coherence of autistic children’s witness accounts is equivalent to TD peers of comparable age and ability

Evaluation of the use of on-board spacecraft energy storage for electric propulsion missions

On-board spacecraft energy storage represents an under utilized resource for some types of missions that also benefit from using relatively high specific impulse capability of electric propulsion. This resource can provide an appreciable fraction of the power required for operating the electric propulsion subsystem in some missions. The most probable mission requirement for utilization of this energy is that of geostationary satellites which have secondary batteries for operating at high power levels during eclipse. The study summarized in this report selected four examples of missions that could benefit from use of electric propulsion and on-board energy storage. Engineering analyses were performed to evaluate the mass saved and economic benefit expected when electric propulsion and on-board batteries perform some propulsion maneuvers that would conventionally be provided by chemical propulsion. For a given payload mass in geosynchronous orbit, use of electric propulsion in this manner typically provides a 10% reduction in spacecraft mass
