Real Zeuthen Numbers for Two Lines
No full textGiven three natural numbers k, l, d such that k + l = d(d + 3)/2, the Zeuthen number Nd(l) is the number of nonsingular complex algebraic curves of degree d passing through k points and tangent to l lines in . It does not depend on the generic configuration C of points and lines chosen. If the points and lines are real, the corresponding number of real curves usually depends on the configuration chosen. We use Mikhalkin's tropical correspondence theorem to prove that for two lines, the real Zeuthen problem is maximal: there exists a configuration C such that . The correspondence theorem reduces the computation to counting certain lattice paths with multiplicitie
Zeuthen–Hicks Bargaining in Electronic Negotiations
No full textWe apply the Zeuthen–Hicks bargaining model in an empirical study of electronic negotiations. Using a typology of bargaining steps based on that model, we study to what extent actual steps conform to the predictions of the model, and the effects of conformity with the model on bargaining outcomes. Results indicate that the model predicts bargaining steps only slightly better than chance, but that steps conforming to the model lead to outcomes that are closer to the efficient frontier, closer to the Nash bargaining solution, and provide higher utility to the party using such steps.© The Author(s) 201

Response to Zeuthen and Zeuthen's Comment to the Editor: Enough Local Hypertonicity Is Enough
No full textAbstractIn a Comment to the Editor, Zeuthen and Zeuthen criticize our treatment of the water cotransport hypothesis. In this response, we argue that we calculated water cotransport as if there were no significant local osmotic gradient generated in the first minute of Na/glucose cotransport. It is surprising to receive this type of criticism from Zeuthen and Zeuthen, as the same treatment was used in at least six studies from his laboratory where it is systematically assumed that “intracellular unstirred layers effects” are negligible. Zeuthen and Zeuthen also state that “the cotransport hypothesis predicts the measurements better than the osmotic hypothesis”. We present a quantitative comparison that challenges this contention. We would like to conclude by stating that our article was not about comparing different numerical models but about an experimental measurement of the local osmotic gradient generated after 20, 40, or 60s of cotransport. Osmotic gradients were indeed detected, and were of appropriate amplitude to explain virtually all water transport observed

Get PDFLouise Zeuthen lægger i sin artikel vægt på repræsentationer af krop og køn i især Thorups store romaner fra 1970’erne og 1980’erne og viser, hvordan etiketten “socialrealisme” er en forfladigelse af en æstetisk bevidst fremstillingsform, som har paralleller til repræsentationer af kroppen i samtidens kunst
