Single period Markowitz portfolio selection, performance gauging and duality: a variation on Luenberger's shortage function

Markowitz portfolio theory (1952) has induced research into the efficiency of portfolio management. This paper studies existing nonparametric efficiency measurement approaches for single period portfolio selection from a theoretical perspective and generalises currently used efficiency measures into the full mean-variance space. Therefore, we introduce the efficiency improvement possibility function (a variation on the shortage function), study its axiomatic properties in the context of Markowitz efficient frontier, and establish a link to the indirect mean-variance utility function. This framework allows distinguishing between portfolio efficiency and allocative efficiency. Furthermore, it permits retrieving information about the revealed risk aversion of investors. The efficiency improvement possibility function thus provides a more general framework for gauging the efficiency of portfolio management using nonparametric frontier envelopment methods based on quadratic optimisation.

O aparelho muscular dos Proglotes de Taenia Saginata

The writers describe the muscular texture of the proglottides of Taenia saginata, Goeze, 1782, based upon microscopical preparations of mature and gravid proglottides stained by several methods. The muscular system of the proglottides of Taenia saginata is disposed mainly in two layers, a longitudinal and external one, and a deeper transverse layer, lining the body parenchym and internal organs. A circular or annular layer ranging under the cuticle is also referred. The writers emphasize the peculiar texture of the smooth muscle fibres, which only excepcionally do exist as isolated fibres, anastomosis between the fibres being the common histological appearence. Special features of the body parenchym such as calcareous bodies and globous nuclea scattered in the parenchym are also described.
