The GH-2000 and GH-2004 projects have developed a method for detecting GH misuse based on measuring insulin-like growth factor-I (IGF-I) and the amino-terminal pro-peptide of type III collagen (P-III-NP). The objectives were to analyze more samples from elite athletes to improve the reliability of the decision limit estimates, to evaluate whether the existing decision limits needed revision, an...

I examine an investor’s portfolio allocation problem across multiple risky assets in the presence of return predictability when, in addition to the predictability evidence, the investor uses conditional asset pricing models to guide him in the portfolio selection decision. I also explore how the uncertainty associated with the model dynamics affects the investor’s optimal portfolio. To analyze ...

We investigate the problem of learning D N F concepts f rom examples using decision trees as a concept description language. Due to the replication problem, D N F concepts do not always have a concise decision tree descrip­ tion when the tests at the nodes are l im­ ited to the in i t ia l at t r ibutes. However, the representational complexity may be overcome by using high level at tr ibutes a...

In previous work, we showed that the critical engagement with a decision support system during its implementation by a project team is an important antecedent for the successful later use of the technology. However, the mechanisms that trigger such critical engagement are so far not well understood. Drawing on Heidegger’s modes of Being-in-the-world this paper provides a theoretical frame to un...

This paper discusses the development of mathematical psychology, decision theory, and behavioral decision research at the University of Michigan in the 1950s and 1960s. It focuses on the question how to understand the connection to economics these three psychological programs considered, and provides a background for understanding subsequent developments of Kahneman and Tversky’s work in the 19...

Call admission control in a wireless cell in a personal communication system (PCS) can be modeled as an M/M/C/C queuing system with m classes of users. Semi-Markov Decision Process (SMDP) can be used to optimize channel utilization with upper bounds on handoff blocking probabilities as Quality of Service constraints. However, this method is too time-consuming and therefore it fails when state s...

In this paper i have adopted an efficient approach for calculating the reliability of the computer communication network with the help of binary decision diagram. The computer communication network has imperfect nodes and imperfect links. It means the nodes as well as the communication links may fail with known probability. The network is represented in the form of a directed graph. First i hav...
