Using a unique firm-level database comprising the top European R&D investors over the period 2002-2013 and running LSDVC estimates, this study finds a significant labourfriendly impact of R&D expenditures. However, this positive employment effect appears limited in magnitude and entirely due to the medium-and high-tech sectors, while no effect can be detected in the low-tech industries. From a ...

Abstract Introduction Investigative interviews and interrogations are a critical component of official inquiries. However, how levels alertness (vs. fatigue) the interviewer impact performance during investigative or their outcomes is unclear.

Academic resilience is defined as the ability to effectively deal with setback, stress or pressure in the academic setting. Although there is a large body of research focusing on general or life resilience, there has been little research into the issue of academic resilience.

In 1978, C. Thomassen proved that in any graph one can destroy all the longest cycles by deleting at most one third of the vertices. We show that for graphs with circumference k ≤ 8 it suffices to remove at most 1/k of the vertices. The Petersen graph demonstrates that this result cannot be extended to include k = 9 but we show that in every graph with circumference nine we can destroy all 9-cy...
