Modelling Techniques

Abstract:The problem of deciding the optimal sequence of diagnostic tests can be structured in decision trees, but unmanageable bushy decision trees result when the sequence of two or more tests is investigated. Most modelling techniques include tests on the basis of gain in certainty. The aim of this study was to explore a model for optimizing the sequence of diagnostic tests based on efficiency criteria. The probability modifying plot shows, when in a specific test sequence further testing is redundant and which costs are involved. In this way different sequences can be compared. The model is illustrated with data on urinary tract infection. The sequence of diagnostic tests was optimized on the basis of efficiency, which was either defined as the test sequence with the least number of tests or the least total cost for testing. Further research on the model is needed to handle current limitations.

Simultaneous Study

SummaryThe development of investigative strategies by decision analysis has been achieved by explicitly drawing the decision tree, either by hand or on computer. This paper discusses the feasibility of automatically generating and analysing decision trees from a description of the investigations and the treatment problem. The investigation of cholestatic jaundice is used to illustrate the technique.Methods to decrease the number of calculations required are presented. It is shown that this method makes practical the simultaneous study of at least half a dozen investigations. However, some new problems arise due to the possible complexity of the resulting optimal strategy. If protocol errors and delays due to testing are considered, simpler strategies become desirable. Generation and assessment of these simpler strategies are discussed with examples.

Theoretical Results

AbstractA Logistic-Normal random variable (Y) is obtained from a Normal random variable (X) by the relation Y = (ex)/(1 + ex). In Monte-Carlo analysis of decision trees, Logistic-Normal random variates may be used to model the branching probabilities. In some cases, the probabilities to be modeled may not be independent, and a method for generating correlated Logistic-Normal random variates would be useful. A technique for generating correlated Normal random variates has been previously described. Using Taylor Series approximations and the algebraic definitions of variance and covariance, we describe methods for estimating the means, variances, and covariances of Normal random variates which, after translation using the above formula, will result in Logistic-Normal random variates having approximately the desired means, variances, and covariances. Multiple simulations of the method using the Mathematica computer algebra system show satisfactory agreement with the theoretical results.

Influential Theory

The purpose of this article is to examine the contributions that might be given by Lutheran political theology to the discourse on global justice. The article offers a critical examination of three different theories of global justice within political philosophy. Contractarian theories are criticized, and a thesis is that it is plausible to argue that justice can be understood as liberation from oppression. From this perspective the article gives an analysis of an influential theory of justice within Lutheran ethics. According to this theory justice is not an equal distribution but an arrangement where the subordinate respect the authority of those in power. This theory is related to a sharp distinction between law and gospel. The main thesis of the article is that Lutheran political theology should take a different approach if it aims to give a constructive contribution to theories of justice. This means that Lutheran ethics should not be based on Creation and reason alone – it should also be based on Christology and Eschatology.

Gadamer’s Concept of Aesthetic Experience as a Possibility for the Orthodox Biblical Theology

Abstract This article finds its inspiration in the new interpretations of Gadamer’s hermeneutics, which underline the turn in his later period, and which focus on the conception of aesthetic experience as an experience of transcendence. The main thesis is that the understanding of artworks, as Gadamer describes them in contrast to the Kantian subjectification of aesthetics, can be paralleled with the way Orthodox biblical theology struggles to approach Holy Scripture in the context of Church and Tradition. The aim of this article is to bring new material to the growing reception of Gadamer among Orthodox scholars, and to initiate further discussion on the topic by showing the parallels and areas where this reception could continue.
