Raising the Barre and Stretching the Canvas: Implementing High Quality Arts Programming in a National Youth Serving Organization

Experiences of the Boys and Girls Clubs of America suggest that large, multidisciplinary youth organizations can establish high-quality arts program

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

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

Among-site variability in the stochastic dynamics of East African coral reefs

Coral reefs are dynamic systems whose composition is highly influenced by unpredictable biotic and abiotic factors. Understanding the spatial scale at which long-term predictions of reef composition can be made will be crucial for guiding conservation efforts. Using a 22-year time series of benthic composition data from 20 reefs on the Kenyan and Tanzanian coast, we studied the long-term behaviour of Bayesian vector autoregressive state-space models for reef dynamics, incorporating among-site variability. We estimate that if there were no among-site variability, the total long-term variability would be approximately one third of its current value. Thus among-site variability contributes more to long-term variability in reef composition than does temporal variability. Individual sites are more predictable than previously thought, and predictions based on current snapshots are informative about long-term properties. Our approach allowed us to identify a subset of possible climate refugia sites with high conservation value, where the long-term probability of coral cover <= 0.1 was very low. Analytical results show that this probability is most strongly influenced by among-site variability and by interactions among benthic components within sites. These findings suggest that conservation initiatives might be successful at the site scale as well as the regional scale.Comment: 97 pages, 49 figure
