The present research used data from Grades 8, 9, and 10 of the 4-H Study of Positive Youth Development, a longitudinal study involving U.S. adolescents, in order to better elucidate the process through which the strengths of youth and the ecological resources promoting healthy development (such as out-of-school-time programs) may contribute to thriving. We examined the relationship between adol...

Assets Coming Together (ACT) for Youth is a community-based, public health youth development (YD) initiative across New York State. Diverse community partnerships and a wide range of community settings have participated in this statewide effort, providing a rich laboratory to study effective partnership development. Based on the experience of the first 6 years of ACT for Youth, this report disc...

Best practice research indicates a need for a policy shift toward positive youth development (YD) principles and strategies. The New York State Youth Development Team (YDT) is a public-private partnership of leading agencies whose holistic vision, "families, schools and communities partner to support the development of healthy, capable and caring youth," requires key stakeholders at all levels ...

Drawing on data collected through evaluations of youth development (YD) programs, including those offered in community-and school-based after-school programs, this article describes practices that support program managers' quests for funds that will sustain programs. Designing YD activities to incorporate skills building (including educational) and recreational and fun activities for adolescent...

A unique analytical result for the Migdal–Kadanoff hierarchical lattice is obtained. The scaling of the defect energy for a zero-dimensional spin glass is derived for a bond distribution that is continuous at the origin. The value of the ‘stiffness’ exponent in zero dimensions, y0 = −1, corresponds to the value also found in one dimension. This result complements and completes earlier findings ...

Upon closer inspection, the classical view of the synchronous relationship between tropospheric methane mixing ratio and Greenland temperature observed in ice samples reveals clearly discernable variations in the magnitude of this response during the Late Pleistocene (<50kyr BP). During the Holocene this relationship appears to decouple, indicating that other factors have modulated the methane ...

Analyses of a sediment core from Highstead Swamp in southwestern Connecticut, USA, reveal Lateglacial and early Holocene ecological and hydrological changes. Lateglacial pollen assemblages are dominated by Picea and Pinus subg. Pinus, and the onset of the Younger Dryas (YD) cold interval is evidenced by higher abundance of Abies and Alnus viridis subsp. crispa. As climate warmed at the end of t...

Greenland ice cores reveal that mean annual temperatures during the Younger Dryas (YD) cold interval--about 12.9 to 11.7 thousand years ago (ka)--and the ~150-year-long cold reversal that occurred 8.2 thousand years ago were ~15° and 3° to 4°C colder than today, respectively. Reconstructing ice-sheet response to these climate perturbations can help evaluate ice-sheet sensitivity to climate chan...

The occurrence of Asian dust storms, and the subsequent transport of yellow dust (YD) greatly influences the air quality of lee-side countries such as Korea and Japan. The dust is also frequently transported in a southward direction by a strong cold high-pressure system that affects the air quality in Taiwan. This study reports the aerosol properties that were monitored continuously at the Taiw...
