he workshop will firstly provide an overview of the problems associated with missing data within the context of clinical trials and how to minimise these. Missing data will be explored by modeling the impact on a number of datasets. This approach will be invaluable in highlighting how alternative methods for controlling for missing data impact differentially on the interpretation of study findings. Popular strategies involve options based on an assessment of the percentage of missing data. More innovative approaches to the management of missing data (e.g. based upon reliability analyses) will be explored and evaluated and the role of the most popular methods of data management explored in several study designs beyond those of the classic randomised controlled trial. Participants will have the opportunity to appraise and debate existing methods of missing data handling.

Efficient and effective Product Lifecycle Management, as an evolution and enhancement of Product Data Management, is of strategic importance for virtually any company. Hence, it is crucial for companies to analyze and evaluate recent trends in information technology (IT) and their implications on Product Lifecycle Management. In this paper, the results of an interdisciplinary study conducted by Siemens AG, a major international technologies firm, and two universities are presented. The study identifies four current trends in IT and then evaluates their potential implications on Product Lifecycle Management. Finally, the IT trends are ranked according to their short and medium term effects on Product Lifecycle Management.

Background: Schools are an ideal setting in which to involve children in research. Yet for investigators wishing to work in these settings, there are few method papers providing insights into working efficiently in this setting.

Objective: The aim of this paper is to describe the five strategies used to increase response rates, data quality and quantity in the TRansport Environment and Kids (TREK) project.

Setting: The TREK project examined the association between neighbourhood urban design and active transport in Grade 5–7 school children (n = 1480) attending 25 primary schools in metropolitan Perth, Western Australia during 2007.

Method: Children completed several survey components during school time (i.e. questionnaire, mapping activity, travel diary and anthropometric measurements) and at home (i.e. pedometer study, parent questionnaire).

Results: Overall, 69.4% of schools and 56.6% of children agreed to participate in the study and, of these, 89.9% returned a completed travel diary, 97.8% returned their pedometer and 88.8% of parents returned their questionnaire. These return rates are superior to similar studies. Five strategies appeared important: (1) building positive relationships with key school personnel; (2) child-centred approaches to survey development; (3) comprehensive classroom management techniques to standardize and optimize group sessions; (4) extensive follow-up procedures for collecting survey items; and (5) a specially designed data management/monitoring system.

Conclusion: Sharing methodological approaches for obtaining high-quality data will ensure research opportunities within schools are maximized. These methodological issues have implications for planning, budgeting and implementing future research.

Learning management systems (LMS) have been a popular tool for delivery of learning content as well as the management of learners and courses. In recent years, the ubiquity of mobile devices such as smartphones and tablets has seen the increased popularity of using them to consume eBooks. While the LMS is popular among administrators, accessing content on mobile devices appear to be the preference of our learners. Furthermore, there are reports on a number of shortcomings with learners using the LMS, e.g., the experience of using LMSes on mobile devices falling short and learners are less engaged interacting with the LMS than with their mobile devices, etc. In this paper, we investigate the idea of using eBooks as an alternative frontend for learners to interact with the LMS. A proof of concept eBook was developed for a data management course to showcase how content on the LMS can be deployed via the eBook interface while connecting our learners to the LMS for learning management. We find that this approach delivers a rich and immersive experience to our learners, as they would expect from their devices. The outcomes also gave us food for thought regarding how LMSes may evolve in the future.
