Micro-Channel Plate (MCP) detectors can suffer from a form of degradation known as gain sag in regions with significant fluence. We have developed a method to recover the total Lyman-Alpha (Ly-[Formula: see text]) emission line (121.6[Formula: see text]nm) flux for the Lyman-Alpha Mapping Project (LAMP) UV imaging spectrograph onboard of the Lunar Reconnaissance Orbiter (LRO), where gain sag issues are important. The constant ratio between the Ly-[Formula: see text] emission line and its ghost image at shorter wavelengths allows for a useful correction factor for the true flux at the Ly-[Formula: see text] region of the detector. A similar method could be used in other spectrographs whenever a ghost image of sufficient brightness is present.

Abstract. To this day, researchers are debating the adequacy of using financial incentives to bolster performance in work settings. Our goal was to contribute to current understanding by considering the moderating role of distributive justice in the relation between financial incentives, motivation, and performance. Based on self-determination theory, we hypothesized that when bonuses are fairly distributed, using financial incentives makes employees feel more competent and autonomous, which in turn fosters greater autonomous motivation and lower controlled motivation, and better work performance. Results from path analyses in three samples supported our hypotheses, suggesting that the effect of financial incentives is contextual, and that compensation plans using financial incentives and bonuses can be effective when properly managed.
