Resale als regulatorische Option zur Umgehung des Anschlussmonopols in Kommunikationsmärkten

Abstract The paper deals with the regulatory remedy of “Wholesale Line Rental” (WLR) also simply called „Resale“. As there is still a major lack of competition regarding voice telephony access, WLR could offer a wider field of strategic actions to alternative network operators so that they have the same scope of possibilities as incumbent operators. It is shown, that service competition does not necessarily cannibalise infrastructure competition, and, in contrary, a complementary relationship can be expected which means that service competition is often essential to enable sustainable infrastructure competition by walking along the ladder of investment. For this purpose a consistent price regulation that also considers the differences in the risks at the various stages of the value chain is inevitable. In this regard Retail-Minus is the preferred price setting method.

Introduction: The scope of possibility in interpreting and promoting research‐based teaching

AbstractResearch‐based teaching is becoming increasingly important as the mandate of higher education institutions is being broadened.

As sociedades aprendem, mas o mundo é difícil de mudar

Aprendizado não é o mesmo que evolução cultural. O aprendizado social não muda o mundo, mas fornece os elementos para mudá-lo. Promove um incremento de variação, aumentando o escopo de possibilidades de evolução.

Studies of trace element transport in plants using high resolution γ-ray spectroscopy and perturbed directional correlation measurements

Two examples are given to illustrate how modern experimental techniques may extend the scope of possibilities of radiotracer applications. The first example refers to the use of a Ge-detector γ-ray spectrometer to measure the transport in plants of 15 elements simultaneously. The second example presented is an in-vivo study of the binding of Cd-ions in plants using meansurements of perturbed γ-γ-directional correlations.

Restriking voltage, and its import in circuit-breaker operation

Restriking voltage and its principal significance are described, and the problem of relating these to circuitbreaker operation in power systems is stated. An instrument for showing inherent restriking-voltage characteristics is described in some detail, reasons being given for the leading features adopted; and the method of operation is outlined. The scope of possibilities in system investigations and in circuit-breaker development is indicated. A short appendix deals with design of the instrument.
