Background: Conservative treatment of patellar tendinopathy has been minimally investigated. Effective validated treatment protocols are required.
Objectives: To investigate the immediate (12 weeks) and long term (12 months) efficacy of two eccentric exercise programmes for the treatment of patellar tendinopathy.
Methods: This was a prospective randomised controlled trial of 17 elite volleyball players with clinically diagnosed and imaging confirmed patellar tendinopathy. Participants were randomly assigned to one of two treatment groups: a decline group and a step group. The decline group were required to perform single leg squats on a 25° decline board, exercising into tendon pain and progressing their exercises with load. The step group performed single leg squats on a 10 cm step, exercising without tendon pain and progressing their exercises with speed then load. All participants completed a 12 week intervention programme during their preseason. Outcome measures used were the Victorian Institute of Sport Assessment (VISA) score for knee function and 100 mm visual analogue scale (VAS) for tendon pain with activity. Measures were taken throughout the intervention period and at 12 months.
Results: Both groups had improved significantly from baseline at 12 weeks and 12 months. Analysis of the likelihood of a 20 point improvement in VISA score at 12 months revealed a greater likelihood of clinical improvements in the decline group than the step group. VAS scores at 12 months did not differ between the groups.
Conclusions: Both exercise protocols improved pain and sporting function in volleyball players over 12 months. This study indicates that the decline squat protocol offers greater clinical gains during a rehabilitation programme for patellar tendinopathy in athletes who continue to train and play with pain.

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.

In recent years, conceptions of teaching held by academic staff have achieved an increased focus in the scholarly and practical work of teaching developers. Views on the impact of conceptions of teaching on improving university teaching, as well as their significance in doing so, vary from those that advocate changing conceptions as a necessary first step in the process of improvement to more recent views that characterize conceptions of teaching as merely artifacts of reflection on teaching. This paper explores this range of views, raises a number of questions about the current accepted views on the importance of conceptions of teaching development work, and challenges the current accepted wisdom in this important area.

The aim of this paper is it to identify whether Australian media companies moved online with a clear business model in mind or in an ad-hoc manner. In-depth interviews were conducted with four Interact media managers from two large Australian media organisations. All four had been involved in Web publishing from its early stages and had extensive knowledge of the development of Web publishing in the industry. The interviews focused on the period around the mid 1990's when the early development of the organisations' websites took place. We also review an analytical approach of examining narratives from research interviews developed by Davidson (Davidson 1997) and Mishler (Mishler1986a, 1986b).

It is not a simple matter to develop an integrative approach that exploits synergies between knowledge management and knowledge discovery in order to monitor and manage the full lifecycle of knowledge and provides services quickly, reliably and securely. One of the main problems is the heterogeneity of the involved resources that represent knowledge. Data mining systems produce knowledge in a form meant to be understandable to machines and on the other hand in knowledge management systems the priority is placed on the readability and usability of knowledge by humans. The Semantic Web is a promising platform to unify this heterogeneity and, in conjunction with novel techniques for Web Intelligence it could offer more then just knowledge - wisdom. The Wisdom Autonomic Grid is an original proposal of a knowledge based Grid that is able to configure and reconfigure itself under varying and unpredictable conditions and optimize its working, performs something akin to healing and provides self-protection, as visioned in the IBM Autonomic Computing initiative. This paper presents an original framework for creating advanced applications to integrate knowledge discovery and knowledge management in the Autonomic Grid and Web environments.
