Scale construction method. It is possible that something similar to your scale will already exist, so including those scale(s) and possible dependent variables in your survey may increase validity of your scale. Begin by generating at least ten items to represent each of the scales.
Do Laboratory Scale Experiments Improve Constructed Wetland Treatment Technology? Jan Vymazal* Faculty of Environmental Sciences, Czech University of Life Sciences Prague, Kamýcka ́169, 165 21 Praha 6, Czech Republic D uring the 1990s, most papers dealing with constructed wetlands (CWs) for wastewater treatment were based on results from the ...
To understand this fully, you need to have learnt the previous essentials course as the chord construction and scale construction topics will be at the base of this new piece of theory.
An enzyme treatment was developed and evaluated for its effectiveness in alleviating bioclogging through a laboratory-scale vertical-flow constructed wetland (VFCW) experiment in this study. The enzyme preparation was a combination of α-glucoamylase and β-glucanase. The results show that the enzyme treatment greatly reduced bioclogging, and ...
