A study of intergovernmental relations in the area of the environment will determine whether the current Canadian federal structure represents a dangerous impediment to the promotion of sustainable development. This paper examines the interjurisdictional quagmire that has developed from the fact that authority over the environment is a functionally concurrent field for the two orders of government. A history of federal-provincial relations in the area of environmental protection is followed by an analysis of the advantages and disadvantages associated with competitive and cooperative federalism. For the purpose of this paper, cooperative federalism is characterized by the presence of a formal institutional system to facilitate interaction between politicians and bureaucrats from both orders of government. Competitive federalism is defined as a system that lacks a formal institutional structure to promote discussion and coordination between federal and provincial officials in a specific field of interest. Last, I examine thirty sustainable development issues following the structure established in Agenda 21 to determine the impact of the present federal system on the development of these objectives. This study concludes that Canadian federalism is not a dangerous impediment to the promotion of sustainable development. Cooperative federalism in a form that does not eliminate the ability of governments to revert to competition promotes the emergence of an institutional system that facilitates information-sharing and discussion between the two orders of government, thus leading to coordinated efforts in the field of the environment. Respect for the current division of powers in this area is also essential to the cohesiveness of Canadian society. Policy-makers and advocates for a sustainable society should focus on working within the present system.

We study the problem of locating two public goods for a group of agents with single-peaked preferences over an interval. An alternative specifies a location for each public good. In Miyagawa (1998), each agent consumes only his most preferred public good without rivalry. We extend preferences lexicographically and characterize the class of single-peaked preference rules by Pareto-optimality and replacement-domination. This result is considerably different from the corresponding characterization by Miyagawa (2001a).

The concept of global justice has been developed to stress the worldwide implications of moral problems. Not much, however, has been written about the actual politics of global justice. This article focuses on public opinion and argues that attitudes about international redistribution are not a simple projection of attitudes about the domestic situation. In countries where domestic income redistribution is seen as an important priority, foreign aid is less popular; where this is less so, there is more concern for the fate of the poor in the South. Far from reflecting a lack of coherence in public opinion, these counterintuitive results need to be understood in connection with policy achievements in donor countries. The authors' empirical findings suggest that although the commitment to redistribute is stronger at the national level, relationships of solidarity do not stop at national boundaries. The achievement of justice at home in fact sustains justice abroad.

Gegenstand der vorliegenden Arbeit ist die Analyse verschiedener Formalismen zur Berechnung binärer Wortrelationen. Dabei ist die Grundlage aller hier ausgeführten Betrachtungen das Modell der Restart-Automaten, welches 1995 von Jancar et. al. eingeführt wurde. Zum einen wird das bereits für Restart-Automaten bekannte Konzept der input/output- und proper-Relationen weiterführend untersucht, sowie auf Systeme von zwei parallel arbeitenden und miteinander kommunizierenden Restart-Automaten (PC-Systeme) erweitert. Zum anderen wird eine Variante der Restart-Automaten eingeführt, die sich an klassischen Automatenmodellen zur Berechnung von Relationen orientiert. Mit Hilfe dieser Mechanismen kann gezeigt werden, dass einige Klassen, die durch input/output- und proper-Relationen von Restart Automaten definiert werden, mit den traditionellen Relationsklassen der Rationalen Relationen und der Pushdown-Relationen übereinstimmen. Weiterhin stellt sich heraus, dass das Konzept der parallel kommunizierenden Automaten äußerst mächtig ist, da bereits die Klasse der proper-Relationen von monotonen PC-Systemen alle berechenbaren Relationen umfasst. Der Haupteil der Arbeit beschäftigt sich mit den so genannten Restart-Transducern, welche um eine Ausgabefunktion erweiterte Restart-Automaten sind. Es zeigt sich, dass sich insbesondere dieses Modell mit seinen verschiedenen Erweiterungen und Einschränkungen dazu eignet, eine umfassende Hierarchie von Relationsklassen zu etablieren. In erster Linie seien hier die verschiedenen Typen von monotonen Restart-Transducern erwähnt, mit deren Hilfe viele interessante neue und bekannte Relationsklassen innerhalb der längenbeschränkten Pushdown-Relationen charakterisiert werden. Abschließend wird, im Kontrast zu den vorhergehenden Modellen, das nicht auf Restart-Automaten basierende Konzept des Übersetzens durch Beobachtung ("Transducing by Observing") zur Relationsberechnung eingeführt. Dieser, den Restart-Transducern nicht unähnliche Mechanismus, wird im weitesten Sinne dazu genutzt, einen anderen Blickwinkel auf die von Restart-Transducern definierten Relationen einzunehmen, sowie eine obere Schranke für die Berechnungskraft der Restart-Transducer zu gewinnen.

In January 1983 a group of US government, industry and university information specialists gathered at MIT to take stock of efforts to monitor, acquire, assess, and disseminate Japanese scientific and technical information (JSTI). It was agreed that these efforts were uncoordinated and poorly conceived, and that a clearer understanding of Japanese technical information systems and a clearer sense of its importance to end users was necessary. That meeting led to formal technology assessments, Congressinal hearings, and legislation; it also helped stimulate several private initiatives in JSTI provision. Four years later there exist better coordinated and better conceived JSTI programs in both the public and private sectors, but there remains much room for improvement. This paper will recount their development and assess future directions.

In Metropolitan Area of Mexico City, most of urban displacements happen through semi formal public transportation: small and medium capacity vehicles operated by small private enterprises, through a concession scheme. This kind of public transportation has been playing a major role in the Mexican capital. On one hand, it has been one of the conditions for urbanization to be possible. On the other hand, despite its uncountable deficiencies, public transportation has allowed for a long time the whole population to be able to move within this huge metropolis. However, that important function with regards to integration has now reached its limits in the most recent suburbs of the city, where a new mode of urbanization is taking place, based on massive production of very big social housing gated settlements. Public transportation tends to constitute here a factor of exclusion and households meet with important difficulties for their daily mobility.
