Managing academic personnel flow at universities.

Universities experience increasing difficulty in staffing their academic positions. Attracting and retaining highly qualified employees in a general problem that has received much attention in recent HRM literature. But several authors have claimed that the academic career has lost much of its attractiveness. This paper presents seven levers that universities may use to enhance their recruitment and retention power on a difficult job market. Suggestions are based on experience from innovative organizations, both universities and business organizations. Special attention is given to the creation of multiple and flexible career paths within academia. We contend that a successful application of these suggestions will require major cultural and institutional change at universities.Retention; Market;

Magnetic and luminescent coordination networks based on imidazolium salts and lanthanides for sensitive ratiometric thermometry

The synthesis and characterization of six new lanthanide networks [Ln(L)(ox)(H2O)] with Ln = Eu3+, Gd3+, Tb3+ , Dy3+ , Ho3+ and Yb3+ is reported. They were synthesized by solvo-ionothermal reaction of lanthanide nitrate Ln(NO3)(3)center dot xH(2)O with the 1,3-bis(carboxymethyl)imidazolium [HE] ligand and oxalic acid (H(2)ox) in a water/ethanol solution. The crystal structure of these compounds has been solved on single crystals and the magnetic and luminescent properties have been investigated relying on intrinsic properties of the lanthanide ions. The synthetic strategy has been extended to mixed lanthanide networks leading to four isostructural networks of formula [Tb1-xEux(L)(ox)(H2O)] with x = 0.01, 0.03, 0.05 and 0.10. These materials were assessed as luminescent ratiometric thermometers based on the emission intensities of ligand, Tb3+ and Eu3+ . The best sensitivities were obtained using the ratio between the emission intensities of Eu3+ (D-5(0) -> F-7(2) transition) and of the ligand as the thermometric parameter. [Tb0.97Eu0.03 (L)(ox)(H2O)] was found to be one of the best thermometers among lanthanide-bearing coordination polymers and metal-organic frameworks, operative in the physiological range with a maximum sensitivity of 1.38%.K-1 at 340 K

Effects of pulsed and continuous jet vortex generators in a turbulent boundary layer flow – an investigation using two high-speed stereo PIV systems

Two high-speed stereo PIV systems have been used for the characterization of pulsed and continuous jet actuators in the turbulent boundary layer wind tunnel at ONERA Lille. The test aimed at generating an aerodynamic database useful for the characterization of (unsteady) vortical structures responsible for the wall-normal fluid exchange which enable an increase of wall-shear stress in the wake of the jet actuator row. Averaging over all velocity measurements of the data-set without regarding the different cycle-phases of the jet pulses and calculating the respective scalars and RMS values is the first step in the analysis of the time series of velocity fields. The second step is averaging the different phase-locked positions per cycle so that a quasi-time-resolved reconstruction of the phase average induced vortical wake flow could be realized. Then, a comparison between continuous and pulsed jets through several criteria and an estimation of the minimal number of independent samples in a typical turbulent boundary layer were performed. This work has been realized in close collaboration between ONERA DAAP in Lille, France and DLR-AS-EXV in Göttingen, Germany
