Rezension zu: Inge Govaere and Hanns Ulrich (eds.): Intellectual Property, Public Policy and International Trade

The contemporary intellectual property rights (IPR) system is not a simple, smoothly working block of rules but is complex and full of ambiguities, and as many argue, imperfections. Some deficits relate on the one hand to the inherent centrality of authorship, originality and mercantilism to the ‘Western’ IP model, which leaves numerous non-Western, collaborative or folkloric modes of production outside the scope of protection. On the other hand, some imperfections stem from the way IPR are granted, whereby creators acquire a temporary monopoly over their works and thus exclude the public from having access to them. In this sense, it is often uncertain whether the existent IPR model appropriately reflects the precarious balance between private and public interests, and whether the best incentives to promote creativity and innovation - the initially stated objectives of intellectual property protection - are offered. The matter becomes still more complicated when one considers that the IPR system is not domestically contained but is globalised and strongly affected by rules at the regional and international levels. The question of whether the balance between private interests and public values is sustained within the international legal framework, epitomised by the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) of the World Trade Organization (WTO), is precisely the topic of the book reviewed here. Review of Intellectual Property, Public Policy, and International Trade, edited by Inge Govaere and Hanns Ullrich, P.I.E. Peter Lang, 2007.

Practice Movements: The Politics of Non-sovereign Power

Practice movements, that is, forms of unorganized collective action, are a central site of politics. Their defining moments are that their goals are expressed in practices rather than in words, and that these “pre-ideological” practices aim at access to or redistribution of goods, whether material or symbolic, rather than at representation. They are transgression rather than resistance in that they transgress restrictions inherent in the material organization of space, property relations, status orders, and normative regulations, be they laws, morals, or customs. Practice movements are above all about access and participation rather than about autonomy, and thus have an ambiguous relation to the transformation of the status quo. Their politics are transformative and they can produce temporary or lasting changes in the material grounds or in the regulation of the everyday life of those who pursue them, and potentially of the normativity and the organization of the wider social order.

Photometric monitoring of non-resolved space debris and databases of optical light curves.

The population of space debris increased drastically during the last years. Collisions involving massive objects may produce large number of fragments leading to significantly growth of the space debris population. An effective remediation measure in order to stabilize the population in LEO, is therefore the removal of large, massive space debris. To remove these objects, not only precise orbits, but also more detailed information about their attitude states will be required. One important property of an object targeted for removal is its spin period and spin axis orientation. If we observe a rotating object, the observer sees different surface areas of the object which leads to changes in the measured intensity. Rotating objects will produce periodic brightness vari ations with frequencies which are related to the spin periods. Photometric monitoring is the real tool for remote diagnostics of the satellite rotation around its center of mass. This information is also useful, for example, in case of contingency. Moreover, it is also important to take into account the orientation of non-spherical body (e.g. space debris) in the numerical integration of its motion when a close approach with the another spacecr aft is predicted. We introduce the two databases of light curves: the AIUB data base, which contains about a thousand light curves of LEO, MEO and high-altitude debris objects (including a few functional objects) obtained over more than seven years, and the data base of the Astronomical Observatory of Odessa University (Ukraine), which contains the results of more than 10 years of photometric monitoring of functioning satellites and large space debris objects in low Earth orbit. AIUB used its 1m ZIMLAT telescope for all light curves. For tracking low-orbit satellites, the Astronomical Observatory of Odessa used the KT-50 telescope, which has an alt-azimuth mount and allows tracking objects moving at a high angular velocity. The diameter of the KT-50 main mirror is 0.5 m, and the focal length is 3 m. The Odessa's Atlas of light curves includes almost 5,5 thousand light curves for ~500 correlated objects from a time period of 2005-2014. The processing of light curves and the determination of the rotation period in the inertial frame is challenging. Extracted frequencies and reconstructed phases for some interesting targets, e.g. GLONASS satellites, for which also SLR data were available for confirmation, will be presented. The rotation of the Envisat satellite after its sudden failure will be analyzed. The deceleration of its rotation rate within 3 years is studied together with the attempt to determine the orientation of the rotation axis.
