Ausgehend von Thomas Nagels Aufsatz " What is it like to be a bat? " und Alan Turings Aufsatz " Computing machinery and intelligence " wird argumentiert, das eine erfolgreiche Interaktion von Menschen und autonomen artifiziellen Agenten vor allem darauf beruht, welche Eigenschaften Menschen jenen Agenten zuschreiben und nicht so sehr, ob diese Agenten jene Eigenschaften wirklich besitzen. Diese...

Alan Turing begins his 1950 Mind article, “Computing Machinery and Intelligence,” with the following straightforward pronouncement: “I propose to consider the question ‘Can machines think?’ ” He quickly (too quickly?) argues for “replacing” the original question with another “which is closely related to it and is expressed in relatively unambiguous words.” (Please note the vagueness of the clai...

This paper outlines the iterative stages involved in designing and developing a blended course of English for General Academic Purposes (EGAP) at Osaka University. First, the basic Successive Approximation Model (SAM 1) is introduced as the guiding instructional design model upon which the course was created. Afterward, the stages of design and development of the blended course are explained wi...

A common analysis objective is estimation of a realized random effect. The parameter underlying such an effect is usually defined as an average response of a realized unit, such as a cluster mean, domain mean, small area mean, or subject effect. The effects are called random effects since their occurrence is the result of some (actual or assumed) random sampling process. In mixed models, random...

A new approach to mean-variance efficient portfolio selection is introduced. The method is based on realized regression theory and the regression based portfolio selection approach of Britten-Jones (1999), yielding a conditional version of the Britten-Jones (1999) method. Some of the noticeable results of the paper are as follows. Firstly, the monetary union may have had a much less important i...

This paper proposes new dynamic component models of returns and realized covariance (RCOV) matrices based on time-varying Wishart distributions. Bayesian estimation and model comparison is conducted with a range of multivariate GARCH models and existing RCOV models from the literature. The main method of model comparison consists of a term-structure of density forecasts of returns for multiple ...

Let G = Z4. We construct examples of G-equivariant entire rational maps from non-singular real algebraic G-varieties to Grassmannians with appropriate actions of G. These examples of strongly algebraicZ4 vector bundles facilitate a key step in the verification of Conjecture1.1 in the general cyclic group action case.

In view of the recent documented hedging bias attributable to failing to accommodate volatility long memory, we suggest to use the simple, yet superior, realized variancecovariance (RVCOV) in dynamic hedging. For its incremental value from intradaily information, model-free and inherent long memory, RVCOV has been shown to be accurate without misspecification bias and easily generalized to high...
