No Advantages in Repairing a Type II Superior Labrum Anterior and Posterior (SLAP) Lesion When Associated With Rotator Cuff Repair in Patients Over Age 50 A Randomized Controlled Trial

Abstract: BackgroundArthroscopic management has been recommended for some superior labrum anterior and posterior (SLAP) lesions, but no studies have focused on patients over 50 years of age with rotator cuff tear and a type II SLAP lesion.HypothesisIn patients over 50 years of age with an arthroscopically confirmed lesion of the rotator cuff and a type II SLAP lesion, there is no difference between (1) repair of both lesions and (2) repair of the rotator cuff tear without repair of the SLAP II lesion but with a tenotomy of the long head of the biceps.Study DesignRandomized controlled clinical trial; Level of evidence, 1.MethodsWe recruited 63 patients. In 31 patients, we repaired the rotator cuff and the type II SLAP lesion (group 1). In the other 32 patients, we repaired the rotator cuff and tenotomized the long head of the biceps (group 2). Seven patients (2 in group 1 and 5 in group 2) were lost to final follow-up.ResultsAt a minimum 2.9 years’ follow-up, statistically significant differences were seen with resp...

MOA-2009-BLG-387Lb: a massive planet orbiting an M dwarf

Abstract: Aims. We report the discovery of a planet with a high planet-to-star mass ratio in the microlensing event MOA-2009-BLG-387, which exhibited pronounced deviations over a 12-day interval, one of the longest for any planetary event. The host is an M dwarf, with a mass in the range 0.07 M_⊙ < M_(host) < 0.49 M_⊙ at 90% confidence. The planet-star mass ratio q = 0.0132 ± 0.003 has been measured extremely well, so at the best-estimated host mass, the planet mass is m_p = 2.6 Jupiter masses for the median host mass, M = 0.19 M_⊙. Methods. The host mass is determined from two “higher order” microlensing parameters. One of these, the angular Einstein radius θ_E = 0.31 ± 0.03 mas has been accurately measured, but the other (the microlens parallax πE, which is due to the Earth’s orbital motion) is highly degenerate with the orbital motion of the planet. We statistically resolve the degeneracy between Earth and planet orbital effects by imposing priors from a Galactic model that specifies the positions and velocities of lenses and sources and a Kepler model of orbits. Results. The 90% confidence intervals for the distance, semi-major axis, and period of the planet are 3.5 kpc < D_L < 7.9 kpc, 1.1 AU < a < 2.7 AU, and 3.8 yr < P < 7.6 yr, respectively.

The costs of activity-based management

Abstract: Activity-based costing and management are now the stock-in-trade of a lucrative industry, with at least one Big Six consultancy operation devoted wholly to their promotion. Both techniques represent a major extension of accountability in the modern corporation, into a zone previously defined in accounting terms as fixed overhead. The mechanics depend on treating the staff department as a mass-producer of repeated acts of routine service (‘activities’) performed ‘for’ particular cost-objects, usually products. By treating these activities as performance indicators, payroll budgets can be linked to activity volumes thus creating pressures for the casualisation of staff employment. The activity frame of reference, particularly when linked with ‘value analysis’, also encourages the stripping-out of all staff work which cannot be accommodated within its definition of activities. This threatens a dumbing-down of staff departments in which non-routine initiatives aimed at competitive advantage in fields such as human resource management or marketing may be stifled because they cannot be accommodated within the language of accountability imposed by ABM. These arguments are concretised through an examination of the ABM treatment of one of its favoured targets: the purchasing function. The contrast between this and the supply chain management approach advocated by practitioners and academics who take the function seriously is a stark illustration of the limitations of ABM as an approach to the management of staff activity.

Towards an Ontology of software maintenance

Abstract: SUMMARY We suggest that empirical studies of maintenance are difficult to understand unless the context of the study is fully defined. We developed a preliminary ontology to identify a number of factors that influence maintenance. The purpose of the ontology is to identify factors that would affect the results of empirical studies. We present the ontology in the form of a UML model. Using the maintenance factors included in the ontology, we define two common maintenance scenarios and consider the industrial issues associated with them. Copyright © 1999 John Wiley & Sons, Ltd.
