The interplay of elicitation and evaluation of trait-expressive behavior: Evidence in assessment center exercises.

In assessment centers (ACs), research on eliciting candidate behavior and evaluating candidate behavior have largely followed independent paths. This study integrates trait activation and trait rating models to posit hypotheses about the effects of behavior elicitation via situational cues on key assessor observation and rating variables. To test the hypotheses, a series of experimental and field studies are conducted.

PINK1 is necessary for long term survival and mitochondrial function in human dopaminergic neurons.

Parkinson's disease (PD) is a common age-related neurodegenerative disease and it is critical to develop models which recapitulate the pathogenic process including the effect of the ageing process. Although the pathogenesis of sporadic PD is unknown, the identification of the mendelian genetic factor PINK1 has provided new mechanistic insights. In order to investigate the role of PINK1 in Parkinson's disease, we studied PINK1 loss of function in human and primary mouse neurons.

The use of surface plasmon resonance (SPR) and fluorescence resonance energy transfer (FRET) to monitor the interaction of the plant G-proteins Ms-Rac1 and Ms-Rac4 with GTP.

Using an RT-PCR approach a cDNA clone, designated Ms-Rac4 and putatively coding for a small GTPase was isolated from Medicago sativa. Ms-Rac4 and the earlier described Ms-Rac1 [Mol. Gen.

Retinoic acid as a chemotactic molecule in neuronal development.

We describe the results of experiments on dissociated cultures of embryonic chick neural tissue which were designed to investigate further the role of all-trans-retinoic acid (tRA) on neurite outgrowth and, by inference, on the developing nervous system in vivo. We show that tRA increases both the number of neurites and the length of neurites extending from these chick neural tube cells at nM concentrations. Secondly, using the newly designed Dunn chamber in which stable gradients of compounds can be generated, we show that neurites respond to a gradient of tRA by growing up the gradient.
