The research design chosen (e.g., experimental, quasi-experimental, one-group pretest-posttest) and operational procedures used (e.g., randomization techniques, adherence standards) determine the ...

This paper systematically reviews this new literature, outlines the benefits and caveats of quasi-experimental methodologies, and verifies the reliability and value of quasi-experimental estimates.

For example, innovative fully printed 3-D architectures have been demonstrated to deliver wideband radiation isotropy, capitalising on additive manufacturing to produce electrically small antennas ...

We also only considered experimental or quasi-experimental studies that relied on a valid measure of housing assistance from administrative records, not self-reports, which are unreliable. 28 (See ...
