In visual surveillance face detection can be an important cue for initializing tracking algorithms. Recent work in psychophics hints at the importance of the local context of a face for robust detection, such as head contours and torso. This paper describes a detector that actively utilizes the idea of local context. The promise is to gain robustness that goes beyond the capabilities of traditi...

The collaboration of faculty and library in Problem Based Learning (PBL) has led to an abundance of studies in the medical and health sciences. This article reports on the emerging roles of librarians in studies on PBL implementation during the past 10 years. The initial analysis revealed studies which focussed on the effects of PBL on library usage. However the trend has since evolved to studi...

The Variations and Variations2 digital music library projects at Indiana University provide a valuable test-bed for user studies. We have used user satisfaction questionnaires, session logging, and contextual inquiry to study digital music library usage by music students. This paper describes our approach with each method and offers a comparison of cost, advantages, and disadvantages of each me...

Emerging evidence suggests that individuals spontaneously self-affirm, by reflecting on values and strengths, in response to daily threats. We examined the prevalence and demographic and well-being correlates of spontaneous self-affirmation in the general population. Participants ( n = 3185) completed the cross-sectional, nationally representative 2013 Health Information National Trends Survey ...

Video transcoding is a mechanism to convert video bit−streams from one coding format to other formats. In this operation, the computational complexity and picture quality are the two most important concerns. MPEG−7 standard defines media Transcoding Hints (THs) in order to both reduce the complexity and improve the visual quality during transcoding process. The basic assumption is that THs are ...

BACKGROUND Historically, all black persons, regardless of ancestry or country of origin, have been categorized as one group for cancer research and control efforts. This practice likely masks variability in exposure to determinants of disease, as well as in risk of cancer incidence and mortality. The current study examines potential differences in knowledge of human papilloma virus (HPV) betwee...

This study investigated the relationship between an institution’s academic library performance measures and undergraduates’ library use and educational outcomes. The sample consisted of 7,958 undergraduates attending 36 colleges and universities representing four institutional types. Regression analyses determined the relationship between academic library performance measures and library use an...
