Recent high food prices and changes in the world food situation are exacerbating the conditions of households that are vulnerable to food insecurity, especially those with weak livelihood strategies. To address the impact of these and other stressors it is necessary to develop a deeper understanding of concepts such as ‘vulnerability’ and ‘food insecurity’. This is challenging as both concepts ...
OBJECTIVES The objective of this study was to investigate demographic and psychosocial predictors of perceptions of risk for colorectal cancer (CRC) in a population-based sample. METHODS The study was a cross-sectional survey of 18,447 men and women aged 55-64 years. A mailed questionnaire assessed perceived comparative risk for CRC along with demographic characteristics (age, gender, ethnici...

BACKGROUND After almost a decade of implementing competency-based programs in postgraduate training programs, the assessment of technical skills remains more subjective than objective. National data on the assessment of technical skills during surgical training are lacking. We conducted this study to document the assessment tools for technical skills currently used in different surgical special...
A growing body of evidence supports a prodromal neurodegenerative process preceding the clinical onset of Parkinson's disease (PD). Studies have identified several different prodromal markers that may have the potential to predict the conversion from healthy to clinical PD but use considerably different approaches.

While drug treatments are important at alleviating some symptoms, there is increasing evidence of the benefits of exercise in enhancing quality of life and health o...
Planar object tracking is an actively studied problem in vision-based robotic applications. While several benchmarks have been constructed for evaluating state-of-theart algorithms, there is a lack of video sequences captured in the wild rather than in constrained laboratory environment. In this paper, we present a carefully designed planar object tracking benchmark containing 210 videos of 30 ...
