The HL7 Clinical Document Architecture.

Many people know of Health Level 7 (HL7) as an organization that creates health care messaging standards. Health Level 7 is also developing standards for the representation of clinical documents (such as discharge summaries and progress notes). These document standards make up the HL7 Clinical Document Architecture (CDA). The HL7 CDA Framework, release 1.0, became an ANSI-approved HL7 standard ...

Impact of comprehensive development zoning on real estate development in Hong Kong

This article presents empirical tests to examine if the comprehensive development area (CDA) where the town planning is more comprehensive has relatively higher economic values than the area outside CDA. The three hypothesis are: (i) CDAs have less environmental complaints than areas outside CDA; (ii) property sales price variances in CDAs are smaller than those in areas outside CDAs; and (iii)...

A wake-up call to CDA and provincial regulatory bodies.

Resistance to 2-chloro-2'-deoxyadenosine of the human B-cell leukemia cell line EHEB.

The effects of 2-chloro-2'-deoxyadenosine (CdA, cladribine), an adenosine deaminase-resistant analogue toxic for both proliferating and resting lymphoid cells, were investigated in the human leukemia cell line EHEB, which was derived from a patient with B-cell chronic lymphocytic leukemia. These cells were found to be less sensitive to CdA than B-cell chronic lymphocytic leukemia lymphocytes (a...

Selective manipulation of target identification demands in visual search: the role of stimulus contrast in CDA activations.

In classic visual pop-out search, response times are slowed remarkably when participants are required to precisely identify (e.g., vertical vs. horizontal orientation) as compared to simply localize (e.g., left vs. right position) a feature singleton target. This cost associated with stimulus identification has been recently proposed (Töllner, Rangelov, & Müller, 2012) to derive from the engage...
