Vietnam veteran as ventriloquist

Because of the shame and controversy surrounding the Vietnam war, a stifling of Vietnam veterans' voices resulted. This paper looks at how this came about, as well as the different ways veterans were regarded in society, and the concomitant affects of this on their psychological welfare. The many films dealing with these events are also discussed.

Prospective randomized controlled trial comparing dynamic hip screw and screw fixation for undisplaced subcapital hip fractures

Background
Neck of femur fractures (NOFFs) are a common cause of morbidity and mortality in our community. Minimally displaced intracapsular fractures are treated with internal fixation by a two-hole dynamic hip screw (DHS) or three partially threaded cancellous screws. Data to support the superiority of one are limited. This prospective randomized controlled trial compares outcomes with these two fixation methods.

Methods
We prospectively recruited patients over 50 years, with an acute fracture subcapital NOFF, who walked and lived independently, and were cognitively intact. They were randomized into DHS or cancellous screw groups and followed up for 2 years (overall 75.9%). Outcomes of mortality, revision, loss of fixation, avascular necrosis, surgical complications, WOMAC, Harris hip score and SF-12 were measured.

Results
We recruited 62 patients (31 DHS, 29 cancellous screws, 2 failed consent). Six deaths (19.3%) were seen in each group. A total of 3.2% of DHS (1 out of 31) and 10.3% (3 out of 29) of cancellous screw patients required re-operation (P = 0.272). There was no statistical significant difference in patient satisfaction, quality of life (QoL), radiological union or osteonecrosis. There are trends towards better functional scores and QoL in cancellous screws, particularly at 1 year (P = 0.0061), but with a higher re-operation rate. There was a combined mortality and transition to institutional care of 40.0% (24 out of 60) at 2 years.

Conclusions
This study found no difference in outcomes between DHS and cancellous screws in the treatment of subcapital NOFFs in a fit, independent population, but we found a high level of physical decline in previously fit, independently ambulating patients. A large, multicentre trial will be required to differentiate between these two fixation methods.

D.A. Pennebaker: Interviews

This wide-ranging and insightful collection of interviews with D. A. Pennebaker (b. 1925) spans the prolific career of this pioneer of observational cinema. From the 1950s to the present day, D. A. Pennebaker has made documentary films that have revealed the world of politics, celebrity culture, and the music industry. Following his early collaborations with Robert Drew on a number of works for television, his feature-length portrait of Bob Dylan on tour in England in 1965 (the landmark film Dont Look Back) established so-called direct cinema as a form capable of achieving broad theatrical release. With Monterey Pop, Pennebaker inaugurated the popular mode of rock concert film (or "rockumentary"), a style of filmmaking he has expanded on through a number of films, including Ziggy Stardust and the Spiders from Mars and Depeche Mode: 101. Pennebaker has always regarded collaboration as an integral part of his filmmaking methods. His long-running collaboration with Richard Leacock and subsequently his work with Chris Hegedus have enriched his approach and, in the process, have instituted collaboration as a working practice integral to American direct cinema. His other collaborations, in particular, with Jean-Luc Godard and Norman Mailer, resulted in innovative combinations of observational techniques and fictional aesthetics. Such films as The War Room, which was about the 1992 Democratic primaries and was nominated for an Academy Award, and the 2009 Kings of Pastry continue to explore the capacities of observational documentary. In 2012 Pennebaker was the first documentary filmmaker to be awarded an Academy Honorary Award by the Academy of Motion Picture Arts and Sciences.

Taking the LEAP with the Oculus HMD and CAD - plucking at thin air?

Achieving adequate visualisation of designs within CAD packages remains a challenge for designers with current methods of 3D CAD visualisation requiring either a high level of technical ability, or expensive hardware and software. The recent re-emergence of consumer VR has lowered the barrier for everyday developers wanting to visualise their designs in true 3D. This paper presents the CAD Interaction Lab (CIL) which employs the Oculus Rift Head Mounted Display (HMD) and Leap Motion Controller (LMC) to provide a low cost method enabling users to use their hands to dissect a mechanic model to manipulate and inspect individual components in realistic 3D. Qualitative observations of user interactions with the CIL show that users were able to intuitively manipulate the CAD model using natural hand movements with only minimal instruction.
