The paper fills this gap, by studying the computational complexity of MMUCA instances under structural and qualitative restrictions, which characterize interactions among bidders and types of bids involved in the various transformations, respectively.
Djajic (1989) indicates that, by relaxing qualitative restrictions (i.e., admission is based largely on skills) on immigration, the labor-importing country may in fact improve the quality of its labor force and reduce the flow of migrants across the border.
The comparison of both studies is, however, subject to two qualitative restrictions: The BGS study took place 6 7 years before the survey presented, for which reason a bias in the results of the comparison cannot be excluded.
Restriction to scalable closed questions reduced qualitative review, and restriction of the survey to English, French and Spanish may have limited the access for some respondents.
Many qualitative or quantitative restrictions for building height have been designated along lakefronts.
We searched eight relevant electronic databases using the terms based on the diagnosis of 'chronic heart failure'heartart failure' and 'congestive heart failure' and qualitative methods, with restrictions to the years 1990-May 2008.
Qualitative congruence between growth restriction and perinatal mortality patterns provides an outcome-based justification for sex-specific birth weight for gestational age standards but not for the available race-specific standards for blacks and whites in the United States.
This is due to the clear distinction between processes and structures as well as the restrictions to qualitative changes in space.
Similar to the quantitative findings, qualitative data suggest fewer restrictions around condoms and pills compared to more invasive family planning methods, with little difference between provider types.
This research highlights the value of a mixed methods approach in the study of duty hour restrictions, with our qualitative arm yielding rich data that complemented and expanded upon the insights derived from the quantitative data.
