Competency management and civil service professionalism in Dutch central government

Competency management has only recently been introduced into personnel management in Dutch central government. The decentralized nature of Dutch central government and its personnel management systems generates marked variation in the degree to which competency management is being applied across the Dutch civil service. The success or otherwise of competency management schemes in both government departments and the higher civil service in The Netherlands, the Senior Public Service, show mixed results. Although all departments have taken steps in the direction of competency management, a few well-developed programmes are in use. The competency management system of the Senior Public Service, then, serves as a basic tool for its management development programmes. Its aim is to enhance civil service professionalism among senior civil servants. The practical effects of competency management programmes, however, can be questioned. Because competency management links personnel development to pay and career decisions, it could well elicit strategic behaviour by staff members; at worst, it could run the risk of becoming a self-defeating initiative.     

The systemic error in the vertical component of handgun bullet trajectory reconstructions

Establishing the path or trajectory of a fired bullet is an often recurring part of shooting incident reconstruction. The current study describes how gravitational pull causes a systemic error on the vertical component of a trajectory reconstruction. Bullet drop, drop angle, and vertical offset are explained and calculated for 10 different handgun/ammunition combinations over a range of distances up to 100 m. The presented results are intended to provide forensic firearm examiners with a reference frame for the magnitude of error introduced on handgun bullet trajectory reconstructions over distance. Threshold values of 20 and 30 m are proposed as conservative distances up to where bullet trajectories can be modeled as straight lines with subsonic/transonic handgun bullets and with supersonic handgun bullets respectively. Both the bullet drop and vertical offset will be below 5 cm at these distances for those categories. The drop angle will be below 0.3°.
