The continuing salience of race as a research variable places researchers in the unenviable position of having to negotiate complicated, and often controversial, terrain.
"Our goal was, 'What's the best you can do?' " Hydraulics seemed too slow to the Bose researchers, and variable rate shock absorbers coming into the market didn't seem to offer enough control to meet the mathematical models.
For the qualitative researcher, these variables may represent a goldmine of potentially relevant information for understanding environmental health.
While improvements in weight and BMI have been reported by other researchers using variable dietary approaches, these lacked a control group, 24, 49, 50 whereas in the present study, women without PCOS acted as the control group and were also matched for age and BMI for further analysis.
Some researchers considered variable-rate transmission in scheduling algorithms [11 15].
The result of the regression analysis is illustrated in table 3. On the basis of comparison with 'basic science researchers, 'the variables that have shown to have a significant relationship include 'clinical researchers' and 'health system researchers'.
The survey questionnaire was developed by the researchers, involving demographic variables, behavioural variables and cognitive variables.
We did however not register teacher vs researcher as a variable, or any other information about the teaching skills, or programme adherence of the teachers, and could thus not control for these possible confounders.
Once the system is as realistic as possible, the researchers introduce a variable such as a flu virus, with a rate and pattern of spread based on its real-life characteristics.
After both conducting and participating in a great many mescaline and LSD sessions — at the time it was routine for scientists to test drugs on themselves — the researchers observed how variable the experience could be, depending on circumstance and mind-set.
