The dangers of resource myopia in work and organisational psychology: a plea for broadening and integration broadening

In this essay the limitations of the traditional quantitative approach in work and organisational psychology are put forward. It is argued that an extension of the methods, a broadening of the type of problems to be addressed, and a stronger integration with associated disciplines as well as with the application and implementation of the research findings are needed to ensure the usefulness and application of future W&O psychology. It is not suggested that micro-level problems should not be investigated, but it is postulated that W&O psychology should not be deprived of the opportunity to tackle other, and often more relevant, meso-and macro-level issues because we lack appropriate tools for attacking them

Measurement of the B0-anti-B0-Oscillation Frequency with Inclusive Dilepton Events

The $B^0$-$\bar B^0$ oscillation frequency has been measured with a sample of 23 million \B\bar B pairs collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we select events in which both B mesons decay semileptonically and use the charge of the leptons to identify the flavor of each B meson. A simultaneous fit to the decay time difference distributions for opposite- and same-sign dilepton events gives $\Delta m_d = 0.493 \pm 0.012{(stat)}\pm 0.009{(syst)}$ ps$^{-1}$.Comment: 7 pages, 1 figure, submitted to Physical Review Letter

Partial discharge measurements of streamers in liquid nitrogen under AC voltages using UHF sensor

The pre-breakdown phenomena, have been studied with the aim to further understand the use of liquid nitrogen as a part of insulation system in High Temperature Superconducting (HTS) devices. Previous studies have shown that streamer discharges in liquid dielectrics can appear in the form of pulse trains which are thought to be the results of density-change channels expanding and collapsing. This behavior cannot be observed by the conventional partial discharge (PD) measurement method due to its narrow bandwidth (less than 600 kHz). Instead, a slowly damped pulse is recorded, which shows the integration of many faster pulses. The application of ultra high frequency (UHF) sensor with the bandwidth up to 3 GHz can provide further details of discharge events during streamer initiation and propagation in LN2. An experiment has been designed to measure discharges using narrow and wideband sensors simultaneously. The conventional method following IEC 60270 standards allow measuring the apparent charge at the terminals while UHF sensor details individual events. In addition, discharge signals can be time correlated to images of density-change streamer captured by high speed digital imaging with stroboscopic backlighting. Analysis of obtained results reinforces the proposed mechanism for the characteristics of streamer production in LN
