The proposed method helps to overcome the existing challenges in assessing impacts of deviations of process variables on safety and economy of a process operation.
The percentage of time spent within the target range was the primary outcome variable of efficacy, and the percentage of time spent outside the target was the outcome variable of safety.
The demographic variables included in this study were chosen based on earlier studies indicating the influence of these variables on safety behaviour concerning stair gates [ 11] (i.e. age and walking ability of the child, number of children in the family, ethnicity and employment status and educational level of the mother and educational level of the father).
Similar regression and correlation analyses were performed using the data in the Northbound direction, however, the models developed and the correlations found revealed even weaker effects of the study variables on safety indicators.
Though most variables of perceived safety from crime and traffic were associated as expected with both objective and self-reported health related physical activity, perception of traffic safety to bicycle yielded weaker and/or non- significant associations in the unexpected direction.
Randomised controlled trials in RA have small numbers of patients (only one >250 patients), 11 short follow-up, and variable reporting of safety outcomes.
This paper is an exploratory study of the relationship of these variables to safety.
Two of the 12 patient safety culture factors were considered outcome variables: "overall perception of safety" and "frequency of events reported".
Factor analysis is also used to define mediator variables reflecting citywide transportation network features and dependent variable of traffic safety.
Selected variables in the margin of safety and reproductive safety studies were subjected to statistical analyses.
