Background Specialist nurses often collaborate with researchers to facilitate recruitment of adult NHS patients, yet little is known about their experiences of inviting participation to research studies. It is well documented that clinical staff involved with recruitment often do not invite all potentially eligible patients, leading to underrecruitment and selection bias. Many barriers and faci...

Through comparative effectiveness research in general, and clinical trials in particular, investigators gain insight into the prevention, diagnosis, and treatment of various illnesses. For this insight to be valuable to patients, the clinical trials must, to the extent possible, reflect the reality that governs the situation. The purpose of randomization in clinical trials is to create comparab...

Although valenced information about novel animals changes the implicit and explicit fear beliefs of children (Field & Lawson, 2003), how it might lead to anxiety is unknown. One possibility, based on cognitive models of anxiety, is that fear information creates attentional biases similar to those seen in anxiety disorders. Children between 7 and 9 years old were given positive information about...

The United States Supreme Court has restricted attorneys from considering the gender and race of potential jurors in their use of peremptory challenges—the practice by which jurors may be removed from a jury without explanation or evidence of potential bias. We propose that forbidding peremptories based on social category information not only fails to decrease biased jury selection, but also en...

This paper evaluates the accuracy of shoreline positions obtained from the infrared (IR) bands of Landsat 7, Landsat 8, and Sentinel-2 imagery on natural beaches. A workflow for sub-pixel shoreline extraction, already tested on seawalls, is used. The present work analyzes the behavior of that workflow and resultant shorelines on a micro-tidal (<20 cm) sandy beach and makes a comparison with oth...

The revised version does not address some of the important limitations highlighted by the previous reviews, in particular the injury incidence calculations. Recall bias for less severe injuries is well established and the notion that the responsible household member will recall all injuries irrespective of severity for all members does not hold good. A quick review of published literature on in...

We demonstrated that a self–other attributional bias impedes interracial friendship development. Whites were given the opportunity to become friends with a White or Black participant. Whites indicated how interested they were in becoming friends and how concerned they were about being rejected as a friend. They also indicated how interested they thought the other person was in becoming friends ...

This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...
