THE EASE PROGRAM: THE DEVELOPMENT OF A DISTRESS TOLERANCE INTERVENTION FOR MIDDLE SCHOOL ADOLESCENTS

Although many middle school adolescents consider the middle school grades to be an exhilarating time of momentous change in their lives, others struggle not only with academic challenges but also with the inability to handle negative emotional states. Middle school adolescents often seek ways to cope with the distress they experience. Evidence indicates that adolescents are rarely adequately equipped with the necessary skills to deal with these stressful situations. Moreover, studies indicate that their distress tolerance, defined as the ability to persist in goal directed activity while experiencing emotional distress, is associated with increased risk behavior. Given preliminary evidence that low distress tolerance is associated with risky health behavior amongst adolescents, the overall goal of this study was to develop an adolescent appropriate intervention for improving distress tolerance skills, drawing on techniques from Dialectical Behavior therapy, with four main objectives: (1) to enable adolescents to understand the relationship between their emotions and behavior; (2) to educate adolescents on how to identify and label their emotions; (3) to teach skills to adolescents that will enable them to cope with their difficult emotions; and (4) to provide adolescents with skills that will enable them to avoid engaging in later risk behavior. To aide in the development of this intervention, a multi-method approach was employed using focus groups (n=20), in depth interviews (n=15) and a 3 round Delphi method (n=12). Results from this study were used to develop, modify and finalize a distress tolerance intervention (EASE- Empowering Adolescents to deal with Stress and Emotions) for middle school adolescents

Development of Atmospheric Tracer Methods To Measure Methane Emissions from Natural Gas Facilities and Urban Areas

A new, integrated methodology to locate and measure methane emissions from natural gas systems has been developed. Atmospheric methane sources are identified by elevated ambient CH4 concentrations measured with a mobile laser-based methane analyzer. The total methane emission rate from a source is obtained by simulating the source with a sulfur hexafluoride (SF6) tracer gas release and by measuring methane and tracer concentrations along downwind sampling paths using mobile, real-time analyzers. Combustion sources of methane are distinguished from noncombustion sources by concurrent ambient carbon dioxide measurements. Three variations on the tracer ratio method are described for application to (1) small underground vaults, (2) aboveground natural gas facilities, and (3) diffuse methane emissions from an entire town. Results from controlled releases and from replicate tests demonstrate that the tracer ratio approach can yield total emission rates to within approximately ±15%. The estimated accuracy of emission estimates for urban areas with a variety of diffuse emissions is ±50%. © 1995, American Chemical Society. All rights reserved

Helping with Inquiries or Helping with Profits? The Trials and Tribulations of a Technology of Forensic Reasoning

The commercialization of forensic scientific provision in the UK over the last two decades has had a major role in shaping a changing epistemic identity for forensic scientists working within this jurisdiction. Efforts to match the presumed epistemological standards of the ‘pure’ sciences have been brought together with concerns about value for money in a new approach to the interpretation of evidence, an activity that lies at the heart of criminal investigative practice. A study of the Case Assessment and Interpretation method developed by members of the UK Forensic Science Service is used to show how a technical innovation in the delivery of forensic science services to the police has instantiated these two recent social processes
