Corporate Training in Virtual Worlds
Charles Nebolsky,Nicholas K. Yee,Valery A. Petrushin,Anatole V. Gershman
Journal of Systemics, Cybernetics and Informatics , 2004,
Abstract: This paper presents virtual training worlds that are relatively low-cost distributed collaborative learning environments suitable for corporate training. A virtual training world allows a facilitator, experts and trainees communicating and acting in the virtual environment for practicing skills during collaborative problem solving. Using these environments is beneficial to both trainees and corporations. Two system prototypes – the sales training and the leadership training virtual worlds – are described. The leadership training course design is discussed in details.
A Bayesian Framework for Combining Valuation Estimates
Kenton K. Yee
Physics , 2007,
Abstract: Obtaining more accurate equity value estimates is the starting point for stock selection, value-based indexing in a noisy market, and beating benchmark indices through tactical style rotation. Unfortunately, discounted cash flow, method of comparables, and fundamental analysis typically yield discrepant valuation estimates. Moreover, the valuation estimates typically disagree with market price. Can one form a superior valuation estimate by averaging over the individual estimates, including market price? This article suggests a Bayesian framework for combining two or more estimates into a superior valuation estimate. The framework justifies the common practice of averaging over several estimates to arrive at a final point estimate.
Star Formation and Galaxy Environment
H. K. C. Yee
Physics , 2000,
Abstract: The dependence of star formation rate on galaxian environment is a key issue in the understanding of galaxy formation and evolution. However, the study of this subject is complex and observationally challenging. This paper reviews some of the current results, drawing mostly from recent large redshift surveys such the LCRS, the MORPH collaboration, and the CNOC1 and CNOC2 redshift surveys.
Introduction to Spin and Lattice Models in the Social Sciences
Kenton K. Yee
Physics , 2001,
Abstract: In recent years, political economists, financial economists, and other social scientists have introduced spin and lattice models into their theoretical tool kit. To this end, the modeling skills of hard scientists may be of assistance. This lecture introduces examples of how these models are used. A simple dynamical model of how legal rules evolve and propagate in the courts is described.
Photometric Redshift Techniques: Reliability and Applications
H. K. C. Yee
Physics , 1998,
Abstract: This article describes the various photometric techniques currently being used, including some preliminary results from the large CNOC2 redshift survey. It also presents a critical look at the reliability of the photometric redshift technique, in part using the HDF results from various groups as a case study.
Opportunities Knocking: Residual Income Valuation of an Adaptive Firm
Kenton K. Yee
Physics , 2000,
Abstract: Maintaining a competitive edge requires a firm to replace deteriorating business lines with new projects. Accordingly, part of a firm's value resides in its ability to exploit new opportunities. This article incorporates adaptation into Ohlson's residual income valuation framework and obtains a non-linear (convex) valuation formula. Although parsimoniously cast, the model makes two predictions which are consistent with phenomena reported in the empirical literature: earnings convexity and complementarity. Moreover, the Appendix introduces a new and powerful Equivalence Theorem. This Equivalence Theorem relates Modigliani-Miller dividend invariance to complementarity and earnings convexity in accounting-based valuation.

Information and Stock Prices: A Simple Introduction
Kenton K. Yee
Physics , 2005,
Abstract: This article summarizes recent research in financial economics about why information, such as earnings announcements, moves stock prices. The article does not presume any prior exposure to finance beyond what you might read in newspapers.
Ownership and Trade from Evolutionary Games
Kenton K. Yee
Physics , 2002,
Abstract: Ownership and trade emerge from anarchy as evolutionary stable strategies. In these evolutionary game models, ownership status provides an endogenous asymmetrizing criterion enabling cheaper resolution of property conflicts.
location.location.location: Internet Addresses as Evolving Property
Kenton K. Yee
Computer Science , 2001,
Abstract: I describe recent developments in the rules governing registration and ownership of Internet and World Wide Web addresses or "domain names." I consider the idea that "virtual" properties like domain names are more similar to real estate than to trademarks. Therefore, it would be economically efficient to grant domain name owners stronger rights than those of trademarks and copyright holders.
NASA ExoPAG Study Analysis Group 11: Preparing for the WFIRST Microlensing Survey
Jennifer C. Yee,Michael Albrow,Richard K. Barry,David Bennett,Geoff Bryden,Sun-Ju Chung,B. Scott Gaudi,Neil Gehrels,Andrew Gould,Matthew T. Penny,Nicholas Rattenbury,Yoon-Hyun Ryu,Jan Skowron,Rachel Street,Takahiro Sumi
Physics , 2014,
Abstract: NASA's proposed WFIRST-AFTA mission will discover thousands of exoplanets with separations from the habitable zone out to unbound planets, using the technique of gravitational microlensing. The Study Analysis Group 11 of the NASA Exoplanet Program Analysis Group was convened to explore scientific programs that can be undertaken now, and in the years leading up to WFIRST's launch, in order to maximize the mission's scientific return and to reduce technical and scientific risk. This report presents those findings, which include suggested precursor Hubble Space Telescope observations, a ground-based, NIR microlensing survey, and other programs to develop and deepen community scientific expertise prior to the mission.
