Essays on wages, promotions and performance evaluations
2017
This dissertation comprises four empirical research articles that use personnel data from a large university and worker-level panel data from Finland to examine the determinants of wages, promotions and employee performance evaluations. The first article employs personnel data to examine the importance of worker output and job seniority as predictors of employee performance evaluations and promotions. The results suggest that better-performing employees – with output measured both in absolute terms and relative to peers – were more likely to be assigned higher performance grades and had a higher probability of being promoted to more complex jobs than their peers with similar characteristics…
Beam-induced and cosmic-ray backgrounds observed in the ATLAS detector during the LHC 2012 proton-proton running period
2016
This paper discusses various observations on beam-induced and cosmic-ray backgrounds in the ATLAS detector during the LHC 2012 proton-proton run. Building on published results based on 2011 data, the correlations between background and residual pressure of the beam vacuum are revisited. Ghost charge evolution over 2012 and its role for backgrounds are evaluated. New methods to monitor ghost charge with beam-gas rates are presented and observations of LHC abort gap population by ghost charge are discussed in detail. Fake jets from colliding bunches and from ghost charge are analysed with improved methods, showing that ghost charge in individual radio-frequency buckets of the LHC can be resol…
