news. If you create conditions incompatible with life, the program lets you know your patient is dead, this is the MacMan equivalent of crashing your airplane in a flight simulator, and should this happen you merely start again, because there is no equivalent to reversing the program and resurrecting the dead. Some of the experiment options include: cutting the buffer nerves, resetting barorece...

f-DERIVATIONS AND (f; g)-DERIVATIONS OF MV -ALGEBRAS

Recently, the algebraic theory of MV -algebras is intensively studied. In this paper, we extend the concept of derivation of $MV$-algebras and we give someillustrative examples. Moreover, as a generalization of derivations of $MV$ -algebraswe introduce the notion of $f$-derivations and $(f; g)$-derivations of $MV$-algebras.Also, we investigate some properties of them.

Running head: PROPENSITY SCORE MATCHING IN SPSS Propensity score matching in SPSS Thoemmes, F. University of Tübingen Author Note

Propensity score matching is a tool for causal inference in non-randomized studies that allows for conditioning on large sets of covariates. The use of propensity scores in the social sciences is currently experiencing a tremendous increase; however it is far from a commonly used tool. One impediment towards a more wide-spread use of propensity score methods is the reliance on specialized softw...

In group theory, it is a fundamental question to determine what information about a group is necessary and sufficient tomake a group finitely presented. In this paper, we develop the theory of Σ-invariants due to Robert Bieri and Ralph Strebel [Bieri] whi provides an answer to this question for the class of metabelian groups. We begin our study of Σ-invariants with a digression on group extens...
