Insulin/IGF and Sex Hormone Axes in Human Endometrium and Associations with Endometrial Cancer Risk Factors
Given an ordered set of points and an ordered set of geometric objects in the plane, we are interested in finding a non-crossing matching between point-object pairs. In this paper, we address the algorithmic problem of determining whether a non-crossing matching exists between a given point-object pair. We show that when the objects we match the points to are finite point sets, the problem is NP-complete in general, and polynomial when the objects are on a line or when their size is at most 2. When the objects are line segments, we show that the problem is NP-complete in general, and polynomial when the segments form a convex polygon or are all on a line. Finally, for objects that are straight lines, we show that the problem of finding a min-max non-crossing matching is NP-complete. © 2012 Elsevier B.V.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Ethical Purchasing Dissonance: Antecedents and Coping Behaviors
The pressure of oversight and scrutiny in the business-to-business purchasing process has the potential to cause psychological distress in purchasing professionals, giving rise to apprehensions about being ethically inappropriate. Utilizing depth interviews with public sector purchasing professionals in a phenomenological approach, the authors develop the notion of ethical purchasing dissonance to explain the psychological distress. An inductively derived conceptual framework is presented for ethical purchasing dissonance that explores its potential antecedents and consequences; illustrative propositions are presented, and managerial implications are discussed
