PEGSAT - First Pegasus Payload

Pegsat was designed, built and tested in slightly more than 6 months to meet the planned launch date for the first launch of the Pegasus vehicle. The primary objective of this multifunction spacecraft was to obtain environmental data from the Pegasus vehicle for use in designing future satellite busses. Taking full advantage of the opportunity, Pegsat also deployed a small Navy experimental satellite, and conducted scientific experiments over Northern Canada in support of the upcoming CRRES mission

Information Literacy and the Internet: Transforming the Practice of Teaching and Corresponding Ethical Consequences

Technology pioneers have witnessed an interesting evolution of the computer over the last thirty years. In the 1970s, educators saw computers as a way of “crunching numbers.

Greenbelt Community Project: Solar energy retrofit for a multi-family dwelling

A cooperative project was initiated between Goddard Space Flight Center and the nearby community of Greenbelt, Maryland. The purpose was to design, install and operate an experimental solar heating system on a group of four tandem town houses. The system was successfully developed and is operating. A description is given of the design, installation, system operation and performance as well as the important considerations for judging the economic feasibility of solar heating systems

Two Paths to Food Addiction: The Role of Impulsivity

Impulsivity has long been associated with substance addiction, despite disagreement regarding the personality trait’s structure. The two-factor theory (Dawe & Loxton, 2004) suggests that impulsivity is comprised of two constructs: reward drive (RD) and rash impulsivity (RI). RD is the purposeful drive to attain reward, whilst RI is conceptualised as disinhibition in response rewarding stimuli. Recently, the 2-Component Approach to Reinforcing Substances Model (2-CARS) (Gullo, Dawe, Kambouropoulos, Staiger, & Jackson, 2010) was applied to two-factor theory to hazardous alcohol use, demonstrating that there are two distinct paths from impulsivity to addiction mediated by cognitive processes. Recently, there has been an emergence of interest into the chronic and compulsive overconsumption of highly palatable calorie-dense foods (‘food addiction’) and the similarities between food addiction and other substance use. In light of this, the present study investigated whether the 2-CARS model translated to food addiction. It was predicted that the two impulsivity constructs would lead to food addiction via eating expectancies and eating style. One hundred and thirty-eight participants comprised of university students and adults from the community completed an online survey consisting of impulsivity, eating expectancies, eating style and food addiction measures. Structural equation modelling revealed the hypothesised model was not supported. Further exploration of theoretically plausible models revealed the relationship between impulsivity and food addiction is more complex than hypothesised. However, significant indirect effects were found from both factors of impulsivity to food addiction in the final model. Results support RD and RI as separate factors of impulsivity and have practical implications for obesity prevention and treatment

Weight & Listen: The role of a podcast in reducing weight concerns in young people

Thesis Abstract This thesis consists of three chapters; the first is a literature review, Chapter Two is an empirical paper and the final paper is a reflective account of the research process. Chapter One details a review of the existing literature concerning Internet-based interventions for addressing eating and weight issues. An overview of the available programs and a methodological critique of the current research are provided. The findings are summarised in terms of clinical implications and recommendations for further exploration are given. The empirical paper in Chapter Two reports on a study examining the use of a podcast in informing young people about weight issues. An Internet-based podcast intervention was provided to participants aged 14-25 years, who had completed a set of questionnaires concerning weight concerns, social anxiety, mood, perfectionism, self-esteem and substance use. Post and follow-up data were also collected in order to examine any effects of the intervention. Results demonstrated that after listening to the podcast, participants demonstrated significant improvements on a number of the measures, most of which were maintained at follow-up. Significant differences were found between participants with high weight concerns and those with low weight concerns on a selection of measures. The discussion includes clinical implications and potential future research directions. The final chapter contains reflections on the research process, including; methodological considerations, personal considerations and future directions. Due to the personal nature of this account, it has been written in the first person narrative. All papers have been written in accordance with guidance for authors provided by The British Journal of Clinical Psychology (see Appendix 2)
