I'm looking for articles for my thesis (Universitas Catholica Sacri Cordis Iesu in Milan) about Underdetermination and the debate between Kukla and Laudan.

The articles I need (I looked for them at the library of my University, searched in the internet, asked to other libraries but had no results)

Sklar, 1982, "Saving the noumena", Philosophical Topics, 13:49-72

Kukla, A., 1993 "Laudan, Leplin, Empirical Evidence and Underdetermination", Analysis, 53: 1-7
Laudan and Leplin, "Determination Underdeterred", Analysis, 53: 8-15

Laudan and Leplin, 1991, "Empirical Equivalence and Underdetermination", Journal of Philosophy, 88: 449-472.

If someone owns them, please let me know.
