On the integrated behaviour of non-stationary volatility in stock markets

This paper analyses the behaviour of volatility for several international stock market indexes, namely the SP 500 (USA), the Nikkei (Japan), the PSI 20 (Portugal), the CAC 40 (France), the DAX 30 (Germany), the FTSE 100 (UK), the IBEX 35 (Spain) and the MIB 30 (Italy), in the context of non-stationarity. Our empirical results point to the evidence of the existence of integrated behaviour among several of those stock market indexes of different dimensions. It seems, therefore, that the behaviour of these markets tends to some uniformity, which can be interpreted as the existence of a similar behaviour facing to shocks that may affect the worldwide economy. Whether this is a cause or a consequence of market globalization is an issue that may be stressed in future work.Comment: 10 pages, 3 figures. Paper presented in the APFA 5 conferenc

Educational planning for utilization of space shuttle (ED-PLUSS). Executive summary: Identification and evaluation of educational uses and users for the STS

The development and application of educational programs to improve public awareness of the space shuttle/space lab capabilities are reported. Special efforts were made to: identify the potential user, identify and analyze space education programs, plan methods for user involvement, develop techniques and programs to encourage new users, and compile follow-on ideas

Identification and evaluation of educational uses and users for the STS. Educational planning for utilization of space shuttle ED-PLUSS

A planning and feasibility study to identify and document a methodology needed to incorporate educational programs into future missions and operations of the space transportation system was conducted. Six tasks were identified and accomplished during the study. The task statements are as follows: (1) potential user identification, (2) a review of space education programs, (3) development of methodology for user involvement, (4) methods to encourage user awareness, (5) compilation of follow-on ideas, and (6) response to NASA questions. Specific recommendations for improving the educational coverage of space activities are provided

Quantum geometry and black hole entropy: inclusion of distortion and rotation

Equilibrium states of black holes can be modelled by isolated horizons. If the intrinsic geometry is spherical, they are called type I while if it is axi-symmetric, they are called type II. The detailed theory of geometry of quantum type I horizons and the calculation of their entropy can be generalized to type II, thereby including arbitrary distortions and rotations. The leading term in entropy of large horizons is again given by 1/4th of the horizon area for the same value of the Barbero-Immirzi parameter as in the type I case. Ideas and constructions underlying this extension are summarized.Comment: Text based on parallel talk given at the VI Mexican School on Gravitation and Mathematical Physics: ``Approaches to Quantum Gravity'', held in Playa del Carmen, Mexico, in November of 2004; IGPG preprint number added; metadata abstract correcte

Experimental Navigation and the Creative Process

For this creative project, I am exploring alternate methods of navigating urban environments, and ways in which this activity can inspire creativity. This process is intended to create a new awareness of the urban landscape, break out of the prescribed, and to inspire innovation. The range of possibilities for this way of navigating is vast, and part of the challenge of my experience has been defining boundaries, assigning variables, and using strategies for exploration making my process inherently morphological. I hope that my work here will encourage others to step out of their comfort zone and experience their environment in a new way

Alien Torts in Europe? Human Rights and Tort in European Law

Human rights are universally recognized. Their enforcement, however, often requires the action of particular states. This paper examines private law reme-dies in tort in several Member states of the European Union to remedy human rights violations occurring outside the European Union. It concludes that the laws examined are examples of universal jurisdiction and rights and duties of private persons under international law, which are two key elements of the post-Westphalian state system
