Enriching Summer Work: An Evaluation of the Summer Career Exploration Program

To determine the impact of the Summer Career Exploration Program (SCEP), a privately funded summer jobs program for low-income teens, P/PV examined the lives of over 1700 applicants. These youth were randomly assigned to participate or to not participate in SCEP in the summer of 1999, and their outcomes were compared at four and twelve months after program application. Researchers found that implementation was strong, but program impacts were less impressive. While SCEPs participants got summer jobs at a substantially higher rate (92%) than the control group (62%), the programs ability to translate this large and immediate summer employment impact into intermediate gains (in terms of future plans, college enrollment, work success, sense of self-efficacy or reduced criminal activity) proved to be negligible. Although impacts were short lived, the report concludes that SCEP and similar programs have an important place in the larger mosaic of supports, programs and opportunities for young people

Fabrication of thick structures by sputtering

Deposit, 5500-gram of Cu-0.15 wt % Zr alloy, sputtered onto copper cylinder to average thickness of 12.29 mm. Structure was achieved with high-rate sputter deposition for about 100 hours total sputtering time. Material had twice the strength of unsputtered material at temperatures to 723 K and equivalent strength at nearly 873 K

Illuminating Solutions: The Youth Violence Reduction Partnership

Over the last decade, P/PV has undertaken several studies of the Philadelphia-based Youth Violence Reduction Partnership (YVRP), an intensive collaboration that targets young people deemed at highest risk of being involved in a homicide. YVRP provides young probationers with enhanced supervision and support, with the goal of keeping them out of trouble and putting them on a path toward productive adulthood

Marine reserve recovery rates towards a baseline are slower for reef fish community life histories than biomass

Ecological baselines are disappearing and it is uncertain how marine reserves, here called fisheries closures, simulate pristine communities. We tested the influence of fisheries closure age, size and compliance on recovery of community biomass and life-history metrics towards a baseline. We used census data from 324 coral reefs, including 41 protected areas ranging between 1 and 45 years of age and 0.28 and 1430 km(2), and 36 sites in a remote baseline, the Chagos Archipelago. Fish community-level life histories changed towards larger and later maturing fauna with increasing closure age, size and compliance. In high compliance closures, community biomass levelled at approximately 20 years and 10 km(2) but was still only at approximately 30% of the baseline and community growth rates were projected to slowly decline for more than 100 years. In low compliance and young closures, biomass levelled at half the value and time as high compliance closures and life-history metrics were not predicted to reach the baseline. Biomass does not adequately reflect the long-time scales for full recovery of life-history characteristics, with implications for coral reef management

Evaluating a Suite of Strategies for Reading Graphic Novels: A Confirmatory Case Study

This article describes a qualitative study conducted by two researchers who are teacher educators and a literacy coach in a private school. The purpose was to determine the effectiveness of a set of strategies for reading and teaching about graphic novels by examining the responses of three elementary-grade teachers in a reading workshop environment to a semester-long professional development. Challenges both expected and unexpected were encountered but results overall were positive for teachers. In addition, they provided guidance to researchers for using the strategies introduced in the professional development in further studies

Targeted Outreach: Boys & Girls Clubs of America's Approach to Gang Prevention and Intervention

This report examines two initiatives developed by Boys & Girls Clubs of America, in cooperation with local clubs, to address the problem of youth gangs in their communities. One strategy is designed to help youth stay out of the gang lifestyle -- Gang Prevention through Targeted Outreach. The second helps youth get out of gangs and away from their associated behaviors and values -- Gang Intervention through Targeted Outreach. The findings indicate the initiatives are able to reach and retain hard-to-reach youth and have positive effects on those involved, including reduction in several delinquent and gang-associated behaviors and more positive school experiences

Climate warming, marine protected areas and the ocean-scale integrity of coral reef ecosystems

Coral reefs have emerged as one of the ecosystems most vulnerable to climate variation and change. While the contribution of a warming climate to the loss of live coral cover has been well documented across large spatial and temporal scales, the associated effects on fish have not. Here, we respond to recent and repeated calls to assess the importance of local management in conserving coral reefs in the context of global climate change. Such information is important, as coral reef fish assemblages are the most species dense vertebrate communities on earth, contributing critical ecosystem functions and providing crucial ecosystem services to human societies in tropical countries. Our assessment of the impacts of the 1998 mass bleaching event on coral cover, reef structural complexity, and reef associated fishes spans 7 countries, 66 sites and 26 degrees of latitude in the Indian Ocean. Using Bayesian meta-analysis we show that changes in the size structure, diversity and trophic composition of the reef fish community have followed coral declines. Although the ocean scale integrity of these coral reef ecosystems has been lost, it is positive to see the effects are spatially variable at multiple scales, with impacts and vulnerability affected by geography but not management regime. Existing no-take marine protected areas still support high biomass of fish, however they had no positive affect on the ecosystem response to large-scale disturbance. This suggests a need for future conservation and management efforts to identify and protect regional refugia, which should be integrated into existing management frameworks and combined with policies to improve system-wide resilience to climate variation and change

The Probing In-Situ With Neutron and Gamma Rays (PING) Instrument for Planetary Composition Measurements

The Probing In situ with Neutrons and Gamma rays (PING) instrument (formerly named PNG-GRAND) [I] experiment is an innovative application of the active neutron-gamma ray technology successfully used in oil field well logging and mineral exploration on Earth over many decades. The objective of our active neutron-gamma ray technology program at NASA Goddard Space Flight Center (NASA/GSFC) is to bring PING to the point where it can be flown on a variety of surface lander or rover missions to the Moon, Mars, Venus, asteroids, comets and the satellites of the outer planets and measure their bulk surface and subsurface elemental composition without the need to drill into the surface. Gamma-Ray Spectrometers (GRS) have been incorporated into numerous orbital planetary science missions. While orbital measurements can map a planet, they have low spatial and elemental sensitivity due to the low surface gamma ray emission rates reSUlting from using cosmic rays as an excitation source, PING overcomes this limitation in situ by incorporating a powerful neutron excitation source that permits significantly higher elemental sensitivity elemental composition measurements. PING combines a 14 MeV deuterium-tritium Pulsed Neutron Generator (PNG) with a gamma ray spectrometer and two neutron detectors to produce a landed instrument that can determine the elemental composition of a planet down to 30 - 50 cm below the planet's surface, The penetrating nature of .5 - 10 MeV gamma rays and 14 MeV neutrons allows such sub-surface composition measurements to be made without the need to drill into or otherwise disturb the planetary surface, thus greatly simplifying the lander design, We are cun'ently testing a PING prototype at a unique outdoor neutron instrumentation test facility at NASA/GSFC that provides two large (1.8 m x 1.8 m x ,9 m) granite and basalt test formations placed outdoors in an empty field, Since an independent trace elemental analysis has been performed on both these Columbia River basalt and Concord Gray granite materials, these large samples present two known standards with which to compare PING's experimentally measured elemental composition results, We will present both gamma ray and neutron experimental results from PING measurements of the granite and basalt test formations in various layering configurations and compare the results to the known composition
