THE CONNEXION BETWEEN OLD AND NEW APPROACHES TO FINANCIAL SATISFACTION by Bernard M.S.van Praag In this paper we compare the new satisfaction evaluation approach, developed in the nineties by Oswald ,Clark , Blanchflower and others with the older income evaluation (IEQ) approach, developed by Van Praag and Kapteyn in the seventies of the previous century. We find that both approaches yield stri...

The Dwarf Planet Ceres revealed the presence of ammonia and other unique properties compared to asteroids in main belt which suggests that it was not formed situ. We model early dynamical evolution outer Solar System study possible mechanisms implant a Ceres-sized planetesimal asteroid from trans-Saturnian region. calculate fraction population planetesimals are captured is range 2.8e-5 1.2e-3 d...

Low-albedo asteroids preserve a record of the primordial solar system planetesimals and conditions in which nebula was active. However, origin evolution these are not well-constrained. Here we measured visible near-infrared (0.5 - 4.0 microns) spectra low-albedo mid-outer main belt. We show that numerous large (d > 100 km) dark (geometric albedo < 0.09) exterior to dwarf planet Ceres' orbit sha...

The CERES/NA45 experiment measures low mass electron pair production in Pb-Au collisions at 158AGeV at the CERN SPS. In this paper, we present the electron pair enhancement in the mass range 0:2 < mee < 0:7 GeV/c 2 , it increases more than linear with charged multiplicity and is most pronounced at low pair pT < 0:5 GeV/c. Transverse mass and rapidity distributions for charged hadrons h + ? h ? ...

The schematic CERES method [?] is a recently developed method of cut elimination for proof schemata, that is a sequence of proofs with a recursive construction. Proof schemata can be thought of as a way to circumvent adding an induction rule to the LK-calculus. In this work, we formalize a schematic version of the infinitary pigeonhole principle, which we call the Non-injectivity Assertion sche...

The mineralogy and geochemistry of Ceres, as constrained by Dawn’s instruments, are broadly consistent with a carbonaceous chondrite (CM/CI) bulk composition. Differences explainable by Ceres’s more advanced alteration include the formation of Mgrich serpentine and ammoniated clay; a greater proportion of carbonate and lesser organic matter; amounts of magnetite, sulfide, and carbon that could ...

Introduction: The main-belt object Ceres (radius≈475 km, density≈2100 kg m-3 , semi-major axis 2.7 AU), is an exciting place to explore planetary hab-itability. Abundant volatiles could have shaped Ceres in a way analogous to that suspected on icy moons. Hydrothermalism: Ceres' surface seems blanketed by products of the interaction between silicate rock and liquid water, including carbonates [1...

In the major reorganisation that took place at Halmstad University during 1999-2000, the new School of Information Science, Computer and Electrical Engineering (IDE) was formed. The School of IDE is divided into five laboratories; Computing and Communication (CC), Electronics and Physics (EF), Intelligent Systems (IS), Mathematics (MA), and Man and Information technology (MI). The division into...
