We consider a convex approximation for integer recourse models. In particular, we show that the claim of Van der Vlerk [83] that this approximation yields the convex hull of totally unimodular (TU) integer recourse models is incorrect. We discuss counterexamples, indicate which step of its proof does not hold in general, and identify a class of random variables for which the claim in Van der Vl...

In this paper we study stability of optimal solutions of stochastic programming problems with fixed recourse. An upper bound for the rate of convergence is given in terms of the objective functions of the associated deterministic problems. As an example it is shown how it can be applied to derivation of the Law of Iterated Logarithm for the optimal solutions. It is also shown that in the case o...

We set out to empirically identify the range and frequency of basic verb alternation types in Japanese, through analysis of the Goi-Taikei Japanese pattern-based valency dictionary. This is achieved through comparison of the selectional preference annotation on corresponding case slots, based on the assumption that selectional preferences are preserved under alternation. Three separate extracti...

In this paper, stability of the optimal solution of stochastic programs with recourse with respect to parameters of the given distribution of random coefficients is studied. Provided that the set of admissible solutions is defined by equa[ity constraints only, asymptotical normality of the optimal solution follows by standard methods, If nonnegativity constraints are taken into account the prob...

In the article we argue for a reconstructive and subject-oriented approach to data collection analysis in order reconstruct perspectives of pupils with linguistically spatially discontinuous school biographies as basis needs analysis. The paper takes an in-depth look at narrative interview such pupil using Documentary Method. Based on analysed passage recourse praxeologically extended sociocult...

Various human rights issues arise from the intersection of adolescent motherhood and HIV. While health may be most obvious means by which to address such through policy development legislative means, right is not only that provide recourse or relief in this regard. This article considers an unexplored avenue approaching reliance on enjoy benefits scientific progress. The International Covenant ...
