Student use of an assessed online discussion space

The dataset contains quantitative information concerning university students' usage of online discussion areas and the impact of the students' participation on their final results.

The data includes the following categories of information:
• student age (whole years at the end of semester);
• student gender (male or female);
• student normal mode of study (on-campus or off-campus);
• student course of study (BTech, BE or other);
• student prior general academic performance (measured at Deakin University by the weighted average mark [WAM]);
• the total number of discussion messages read (or at least opened) by the student;
• the total number of new/initial discussion postings made by the student;
• the total number of follow-up/reply discussion postings made by the student; and
• the final unit mark obtained by the student.

Effect of low-dose mobile versus traditional epidural techniques on mode of delivery: a randomised controlled trial

Background

Epidural analgesia is the most effective labour pain relief but is associated with increased rates of instrumental vaginal delivery and other effects, which might be related to the poor motor function associated with traditional epidural. New techniques that preserve motor function could reduce obstetric intervention. We did a randomised controlled trial to compare low-dose combined spinal epidural and low-dose infusion (mobile) techniques with traditional epidural technique.
Methods

Between Feb 1, 1999, and April 30, 2000, we randomly assigned 1054 nulliparous women requesting epidural pain relief to traditional (n=353), low-dose combined spinal epidural (n=351), or low-dose infusion epidural (n=350). Primary outcome was mode of delivery, and secondary outcomes were progress of labour, efficacy of procedure, and effect on neonates. We obtained data during labour and interviewed women postnatally.
Findings

The normal vaginal delivery rate was 35·1% in the traditional epidural group, 42·7% in the low-dose combined spinal group (odds ratio 1·38 [95% CI 1·01–1·89]; p=0·04); and 42·9% in the low-dose infusion group (1·39 [1·01–1·90]; p=0·04). These differences were accounted for by a reduction in instrumental vaginal delivery. Overall, 5 min APGAR scores of 7 or less were more frequent with low-dose technique. High-level resuscitation was more frequent in the low-dose infusion group.
