Youth And Adult Community Member Beliefs About Inupiat Youth Suicide And Its Prevention, Lisa Wexler, Brenda Goodwin Oct 2006

Youth And Adult Community Member Beliefs About Inupiat Youth Suicide And Its Prevention, Lisa Wexler, Brenda Goodwin

Lisa Wexler

Objectives. To better understand youth and adult community members’ perceived causes and possible preventative steps to address the high Inupiat youth suicide rates in Northwest Alaska. Study Design. A five-item, open-ended survey focusing on community members’ perceptions of suicide causes, warning signs, and protective factors was administered in the twelve Native villages served by the Maniilaq Association, a native non-profit organization. Methods. A total of 382 surveys were completed. Qualitative answers were assigned to categories by two reviewers. Main categories are described reflecting the percentages of all response categories and those of youth and adult respondents. To discern whether the …

Photochemical and transport processes involving reactive nitrogen compounds were studied in plumes of urban pollutants using measurements obtained from the NOAA WP-3 aircraft during the ICARTT study in July and August 2004. Observations close to Boston and New York City were used to characterize urban emissions, and plume transport and transformation processes were studied in aged plumes located up to 1000 km downwind from the east coast of North America. Pollution was observed primarily below 1.5 km altitude in well-defined layers that were decoupled from the marine boundary layer. In aged plumes located over the North Atlantic Ocean, the nitric …

Nitrogen oxides are important to the regulation of ozone throughout the Earth’s atmosphere. Of particular interest for regional air quality is photochemical production and nocturnal destruction of O3 in the lower troposphere in high NOx(=NO + NO2) environments. Nocturnal tropospheric odd oxygen (Ox), defined as O3 + NO2 + 2NO3 + 3N2O5, is used to assess the impact of NOx emissions on nocturnal O3 loss. Recent aircraft measurements of the components of Ox and HNO3 yield a detailed accounting of the nocturnal Ox budget in a regionally polluted environment. The analysis demonstrates the role of NO3 and N2O5 reactions in …
