Virtue as Likeness to God in Plato and Seneca

Abstract: IN THE CENTER OF RAPHAEL’S FAMOUS PAINTING, “The School of Athens,” Plato stands pointing to the heavens, and Aristotle stands pointing to the ground; there stand, that is, the mystical Plato and the down-to-earth Aristotle. Although it oversimplifies, this depiction makes sense for the same reason that Aristotle continues to enjoy a presence in modern moral philosophy that Plato does not: quite simply, Plato’s ethics looks too fantastic. And Plato’s ethics never looks more fantastic than in the claim that our highest good is to be like God. We find this view, in various forms, in the Phaedrus, Timaeus, Laws, Republic, and Theaetetus, as well as in the Phaedo and Philebus,1 and the ancient Platonist Alcinous in his Handbook of Platonism tells us that likeness to God (oJmoivwsi~ qew/`) is Plato’s “official” position on our final end.2 Nonetheless, this view receives very little press today: many philosophers are unaware of it; some have simply ignored it or dismissed it as an idle metaphor; and most of those who have taken it more seriously have also tended to find it too otherworldly to be of much relevance to us. This latter response is due in large measure to viewing likeness to God from the perspective of the ancient Neoplatonist Plotinus.3 But there is certainly no guarantee that Plotinus’s perspective on likeness to God gives us an especially accurate reconstruction of Plato’s view; indeed, the interpretation of this idea was a matter of considerable controversy among Neoplatonists, some of whom offered far less other-worldly interpretations than Plotinus’s.4

Boom–Bust Cycles and the Forecasting Performance of Linear and Non-Linear Models of House Prices

Abstract: The tremendous rise in house prices over the last decade has been both a national and a global phenomenon. The growth of secondary mortgage holdings and the increased impact of house prices on consumption and other components of economic activity imply ever-greater importance for accurate forecasts of home price changes. Given the boom–bust nature of housing markets, nonlinear techniques seem intuitively very well suited to forecasting prices, and better, for volatile markets, than linear models which impose symmetry of adjustment in both rising and falling price periods. Accordingly, Crawford and Fratantoni (Real Estate Economics 31:223–243, 2003) apply a Markov-switching model to U.S. home prices, and compare the performance with autoregressive-moving average (ARMA) and generalized autoregressive conditional heteroscedastic (GARCH) models. While the switching model shows great promise with excellent in-sample fit, its out-of-sample forecasts are generally inferior to more standard forecasting techniques. Since these results were published, some researchers have discovered that the Markov-switching model is particularly ill-suited for forecasting. We thus consider other non-linear models besides the Markov switching, and after evaluating alternatives, employ the generalized autoregressive (GAR) model. We find the GAR does a better job at out-of-sample forecasting than ARMA and GARCH models in many cases, especially in those markets traditionally associated with high home-price volatility.

The International Expansion of U.S. Franchise Systems: Status and Strategies

Abstract: This paper presents the survey results of U.S. franchise systems' participation in international markets. The results illustrate the entry motivations, ownership practices, marketing strategies, profit profiles and problems inherent in the operation of U.S. franchise operations abroad.

Volume IV. The DUNE far detector single-phase technology

Abstract: The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. DUNE is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. Central to achieving DUNE's physics program is a far detector that combines the many tens-of-kiloton fiducial mass necessary for rare event searches with sub-centimeter spatial resolution in its ability to image those events, allowing identification of the physics signatures among the numerous backgrounds. In the single-phase liquid argon time-projection chamber (LArTPC) technology, ionization charges drift horizontally in the liquid argon under the influence of an electric field towards a vertical anode, where they are read out with fine granularity. A photon detection system supplements the TPC, directly enhancing physics capabilities for all three DUNE physics drivers and opening up prospects for further physics explorations. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume IV presents an overview of the basic operating principles of a single-phase LArTPC, followed by a description of the DUNE implementation. Each of the subsystems is described in detail, connecting the high-level design requirements and decisions to the overriding physics goals of DUNE.
