The objective of the CSR Corpus Development is to collect and deliver a large corpus of continuous speech data to support DARPA research efforts in continuous speech recognition (CSR). The CSR corpus is intended to be task independent and to consist of speech that is similar to that which would be expected from eventual users of real world CSR systems. Toward these ends, the current pilot colle...

Knowing where people look is a useful tool in many various image and video applications. However, traditional gaze tracking hardware is expensive and requires local study participants, so acquiring gaze location data from a large number of participants is very problematic. In this work we propose a crowdsourced method for acquisition of gaze direction data from a virtually unlimited number of p...

Fis protein and DNA Fis, under the control of the T7 RNA polymerase (Pan et al. 1996), was expressed by auto-induction (Studier 2005). Extracts were prepared using a French Press and nucleic acids were removed by precipitation with 0.35% polyethyleneimine followed by precipitation with ammonium sulfate (80% saturation). Fis was purified by FPLC chromatography over a Bioscale S20 (Bio-Rad) colum...

In this column we provide a context for many of the types of data collection techniques used with human participants. We will not discuss methods for assessing diagnostic status, but we will provide some information about developing or evaluating a questionnaire, test, or other data collection technique. Research approaches or designs are approximately orthogonal to the techniques of data colle...

This focus issue of Spine is dedicated to measurement of clinical outcomes. At the practical level this is hard to do; however, at a scientific level it is essential. Those involved in clinical research or interested in collecting data in their own practices struggle with decisions about which instruments to use in collecting data and when to use them. Even when the relevant outcomes of a treat...
