Un partenariat public-privé rigide ou flexible ? Théorie et application aux concessions routières à péage

In this article, we explore the contractual design of toll road concession contracts. We highlight the fact that contracting parties try to sign not only complete rigid contracts in order to avoid renegotiations but also flexible contracts in order to adapt contractual framework to contingencies and to create incentives for cooperative behavior. This gives rise to multiple toll adjustment provisions and to a tradeoff between rigid and flexible contracts. Such a tradeoff is formalized using an incomplete contract framework - including ex post maladaptation and renegotiation costs - and propositions are tested using an original database of 71 concession contracts. Our results suggest an important role for economic efficiency concerns, as well as politics, in designing such public-private contracts. Codes JEL : D23, H11, H54, L14, L9.

A diagram of public spaces within urban landscape as a strategy for sustainable urban planning in Chinese cities

Destruction of historical urban fabric in many Chinese cities and towns, without the possibility of its recovery as an urban asset, leads us to consider alternative strategies and criteria for formulating new urban projects, using creative urban planning instruments and strategies to provide a sense of place and identity to the urban landscape. The challenge is to set up an urban structure that constitutes a spatial reference system, a structure consisting of a set of urban landmarks that construct a system of related public spaces, endowed with collective significance and identity. Such a network could include a wide variety of urban typologies and natural elements. An important result of this strategy would be the recovery of the social and cultural values attached to the natural landscape in Chinese civilization. Hangzhou city will be analyzed as a case study

Inclusion and empowerment in public art and urban design

To involve citizens in developing the processes of city making is an objective that occupies part of the agenda of political parties in the context of the necessary renewal in representative democracy. This paper aims to provide some answers to the following questions: Is it possible to overcome the participatory processes based exclusively on the consultation? Is it possible to"train" residents to take an active role in decision-making? How can we manage, proactively, the relationship between public actors, technicians and politicians, in a participatory process? We analyse the process development for creating the Wall of Remembrance in the Barcelona neighbourhood of Baró de Viver, a work of public art, created and produced by its neighbours, in the context of a long participatory process focused on changing the image of the neighbourhood and the improvement of public space. This result and this process have been possible in a given context of cooperation among neighbours, local government and the research team (CR-Polis, Art, City, Society at the University of Barcelona). The development of a creative process of citizen participation between 2004 and 2011 made possible the direct management of decision making by the residents on the field of the design of public space in the neighbourhood. However, the material results of the process does not overshadow the great achievement of the project: the inclusion of a neighbourhood in taking informed decisions because of their empowerment in public space design and management of their remembrances.

Urban transport governance reform in Barcelona

The unusual mixed public-private structure of the urban bus market in the metropolitan area of Barcelona provides an interesting context in which to analyze the management challenges and opportunities of the partial privatization of public services. Initiatives used by the public regulator to promote competition for contracts, such as short term concessions to private contractors and the removal of entry barriers, have considerable potential for improving efficiency and quality. The growth in the share of routes managed by private firms in recent years shows that privatization is a credible threat that may well stimulate improved performance among public managers. The type of reform implemented in Barcelona is of interest to all metropolitan areas large enough to operate under constant returns to scale regimes, and suitable for potential concessions of routes in segregated areas inside the metropolitan area, so as not to miss out on the benefits of economies of density.

A Home at School: Building Stronger Indigenous People through Cultural Resurgence in an Urban Ontario Public School Context.

In this thesis, I work through the educational narratives of young Aboriginal women and men as I explore the relationship between cultural programming and student engagement. My analysis is structured through a collaborative Indigenous research project. My overarching task is to explore how a cultural support program, the Native Youth Advancement with Education Hamilton (NYA WEH) Program, offered at Sir John A. Macdonald Secondary School, located in Hamilton, Ontario, Canada, attempts to re-imagine Aboriginal education in ways that directly challenge the residential school legacy. In particular, I work to illuminate how particular forms of Aboriginal education are connected to the graduation rates of Aboriginal youth. I argue that the ways in which the NYA WEH Program navigates Native Studies curriculum, relationships, and notions of culture and tradition are significant to the engagement of Aboriginal youth. This research develops theoretical connections between the contemporary experience of Aboriginal social inequality and educational initiatives which attempt to reverse that legacy. By placing the NYA WEH Program narratives side-by-side with literature supporting Aboriginal education for Self-determination, I work to learn how to best support and encourage Aboriginal student engagement in secondary schools across Ontario.

The neoliberalization of street vending policy in Lima, Peru: the politics of citizenship. property and public space in the production of a new urban marginality

Neoliberalism is having a significant and global impact on political, social and economic life across spaces. This work illustrates how neoliberalism is attempting to change the ways in which the urban poor - particularly those that participate in street vending - use urban spaces in Lima, Peru. Using municipal policies, newspaper articles and local academic texts I argue that there is a changing marginality in Lima that is being experienced by street vendors, and currently in los canas of Lima. In particular, I discuss formalization, a neoliberal strategy in street vending policy, which is used with eradication and social assistance strategies in attempts to re-regulate street vendors.

“Superficial Water Concessions In Light Of The General Theory of the Administrative Act” The Incidence of the Public Law’s Dogmatic Tradition of Public Law Within Environmental Law

This paper seeks the determine the ways in which anomalous decisions derived from the particularization and constitutionalization of environmental law can arise given the general theory of administrative action. This is seen through the lens of a study and characterization of administrative decisions issued by the Regional Autonomous Corporation of Cundinamarca –CAR- within the superficial water concessions procedure. It also discusses the conceptual contents of these licenses.

Protection of Urban Lands: Advances in Medellin’s Public Policy

The problem of land ownership protection in this country is an issue that must be faced by those who have as part of their responsibilities the recognition, the restitution and the reparation of victims of forced displacement. One of the points that must be analyzed is the protection of ownership of urban lands, a subject falling under municipal responsibility. The development of a public policy by the City of Medellín for the protection of such lands is a significant advance for the creation of protocols and for the return of rights to those who have adandoned their lands because of violence or who have been divested of their homes in urban areas.

Qualifying urban outskirts and public areas A refl exion from Bogata’s public policies

This article presents the results and conclusions obtained from an investigation into the possibilities of qualifying urban outskirts of Bogota with regard to the construction of public areas. The discussion presents the results obtained in previous investigations which give reason to conclude that the city’s outskirts are currently equipped with insuffi cient basic urban services and equipment. Questions are raised in regards to the proposals of the Plan for Territorial Organization (POT as abbreviated in Spanish) according to now known facts. From analysis both of currently known facts as well as the proposals of the Plan for Territorial Organization advancement is made in the analysis of the existing possibilities in the latter scenario to improve the condition of the admittedly unarticulated and defi cient urban outskirts, especially for the development of low cost housing.

Public awareness of, and attitude to, Reading's urban gardens: the findings of a questionnaire survey

This paper records and analyses the results of a questionnaire survey, undertaken in Reading in January and February 1994, into the awareness and use of Reading's town centre gardens. The results indicate that although the majority of those interviewed were aware of one or more of the gardens, relatively few visit any of the gardens and, of those who do, the majority visit infrequently. Although the gardens are generally very well liked by those who use them, no clear reasons emerge as to the motivation for visiting, beyond using them as a short cut or as a source of fresh air and tranquillity. Equally, beyond the provision of information and signposting, there appears to be little to turn current non-users into users of the gardens. The report concludes that beyond some managerial issues such as safety and cleanliness, the Borough Council needs to address the extent to which the gardens could play a more central role in the life of the town and, if this is the case, how this might be achieved.
