The paradigm used here offers a promising approach to further explore the time course of art perception, thus helping to unravel the perceptual and cognitive processes that underlie the phenomenon of art and the fascination it exerts. (C) 2011 Elsevier Ltd. All rights reserved.”
“Purpose: selleck chemical Compared to physicians paid on salary (ie employed), those who own their practice (ie self-employed) derive financial benefit from providing more care. Whether the volume based incentives of ownership influence physician use of other ancillary services, like
diagnostic imaging, remains unknown. We explored this possibility among urologists.
Materials and Methods: We used data from the National Ambulatory Medical Care Survey (2006 to 2007)
to identify outpatient urology visits. We determined whether the urologist who was responsible for the encounter was employed or self-employed. We calculated the proportion of visits at which imaging was ordered, and we evaluated for a difference between visits directed by employed vs self-employed urologists. We used multivariable logistic regression to measure the relationship between urologist employment status and imaging use, adjusting for patient, provider and practice level characteristics.
Results: More than 1 in 5 urology visits resulted in imaging. While SB202190 in vivo imaging use did not vary by measurable patient or practice level characteristics, self-employed urologists ordered imaging more often than employed urologists (24.2% vs 13.2%, respectively, p <0.001). In fact, the odds of a patient receiving imaging were almost 2-fold greater if seen by a self-employed urologist (OR 1.84, 95% CI 1.18-2.87). On stratified analysis an independent association between employment status and imaging use was observed for urolithiasis (OR 4.76, 95% CI 1.30-17.4) and hematuria visits (OR 5.52, 95% CI 1.23-24.8).
Compared with employed urologists, those who are self-employed have more resource intense practice styles with respect to imaging use.”
“Event-related potential studies have identified the N170 as the key neurophysiological marker of human face processing. This functional association relies on the observation of a larger N170 amplitude BX-795 in vivo to faces than items from all other visual object categories. However, N170 amplitude is modulated by stimulus variations like viewpoint, size and symmetry, and studies comparing similarly sized and symmetric full-front faces and other objects have failed to find amplitude differences. Here we tested whether the effect of inversion – an increase in N170 amplitude seen for faces presented upside down – is similarly observed for full-front views of cars. Participants discriminated pictures of faces and cars, which were presented upright and inverted, and either in full-front view orvarying in size, orientation and viewpoint.
