Fly Me to the Moon: The Determinants of Secondary Jobholding in Germany and the UK

Fly Me to the Moon: The Determinants of Secondary Jobholding in Germany and the UK This paper analyzes the determinants of secondary jobholding in Germany and the UK. Although differing in labor market regulations, moonlighting is a persistent phenomenon in both countries. Using panel data from the BHPS and the SOEP, reduced form participation equations are estimated for male and female workers...

Time for Me to Fly: Predicting Director Exit at Large Firms

One of the great unanswered questions in governance research is, Why do directors serve on boards? Drawing on self-determination theory, a theory of total motivation that combines both intrinsic and extrinsic motivations, we find that the prestige associated with being a director, the ability to have influence, and identification with the director role make directors less likely to exit; howeve...

Low-Thrust Trajectories to the Moon

In this paper the problem of sending a spacecraft from Low Earth Orbit (LEO) to the Moon with minimum fuel consumption is considered. It is assumed that the "Two-Body model" approximation is valid in all phases of the mission and that the final orbit around the Moon is polar. The first part deals with impulsive maneuvers, and obtain a set of values for fuel expenditure and trip time for several...

Low Energy Transfer to the Moon

Abstract. In 1991, the Japanese Hiten mission used a low energy transfer with a ballistic capture at the Moon which required less 1V than a standard Hohmann transfer. In this paper, we apply the dynamical systems techniques developed in our earlier work to reproduce systematically a Hiten-like mission. We approximate the Sun-Earth-Moon-spacecraft 4-body system as two 3-body systems. Using the i...
