CLOSER: A Collaborative Locality-aware Overlay SERvice
Current Peer-to-Peer (P2P) file sharing systems make use of a considerable percentage of Internet Service Providers (ISPs) bandwidth. This paper presents the Collaborative Locality-aware Overlay SERvice (CLOSER), an architecture that aims at lessening the usage of expensive international links by exploiting traffic locality (i.e., a resource is downloaded from the inside of the ISP whenever possible). The paper proves the effectiveness of CLOSER by analysis and simulation, also comparing this architecture with existing solutions for traffic locality in P2P systems. While savings on international links can be attractive for ISPs, it is necessary to offer some features that can be of interest for users to favor a wide adoption of the application. For this reason, CLOSER also introduces a privacy module that may arouse the users' interest and encourage them to switch to the new architectur
Conceptual models of urban environmental information systems - toward improved information provision
Cities are the hub of European society - for over a millennium, they are the locus of social, political
and economic development. As the core of intensive and creative human activity, they are also the
place where the environmental externalities that accompany rapid development are most visible.
The environmental consequences of urban development have been recognised long ago, as in the
case of London, where in 1388 legislation was introduced to control pollutant emissions
(Lowenthal, 1990). Similar historical environmental regulations can be demonstrated for many
cities in Europe. However, while for most of history those who govern the city (be it the sovereign,
city elders or local government) where responsible for the control, mitigation and management of
the common environment in the city, the last 30 years are a period of profound change. This is due
to the trend toward improved participation in environmental decision making . a more inclusive and
open approach to decisions that deal with the city commons. This change did not occurre overnight
but rather gradually. For example, in the United Kingdom, it was the Town and Country Planning
Act of 1947 which introduced public scrutiny to changes in the urban form (Rydin, 1998), or the
development of public involvement in environmental impact assessment of urban projects as
developed in many countries throughout the developed world during the 1970s and 1980s (Gilpin
1995). These changes accelerate within the last three decades, and especially since the publication
of .Our Common Future. (WCED and Brundtland 1987), the acceptance of the .Sustainable
Development. principles and the Rio conference. A quiet (mini) revolution happened in Europe not
long ago, toward the end of 1998 when the members of the United Nations Economic Commission
for Europe (UN/ECE) signed the .Convention on Access to Information, Public Participation in
Decision Making and Access to Justice in Environmental Matters. - the Aarhus Convention
(UN/ECE 1998). The convention is expected to come into force by the end of 2001, and calls the
governments and public authorities to open up access to environmental information as a means to
improve public participation in environmental decision making and awareness of environmental
issues (UN/ECE, 1998).
However, these declarations on the value and importance of environmental information do not
match our level of understanding on the role of environmental information in decision making
processes, and especially on the role of information in improving awareness and participation.
Therefore, it is useful to take a step back, and to try and evaluate how environmental information
and access to it and its use support public involvement in such processes.
This paper is aimed to offer a framework that can assist us in the analytical process of
understanding environmental information use. It focuses on public access and assumes that
environmental information will be delivered to the public through the Internet. Such assumption is
based on the current trend within public authorities is to use Information and Communication
Technology (ICT) as a major delivery medium and it seems that it will become more so in the near
future (OECD 2000).
The framework which this paper presents, is based on Soft Systems Methodology (SSM) study
which unpacked some of the core issues relating to public access and use of environmental
information (Haklay, 2001). Although the aim here is not to discuss the merits of SSM, but to focus
on the conceptual models, some introduction to the techniques that are used here is needed.
Therefore, the following section opens with introduction to SSM and its techniques. The core of the
paper is dedicated to the development of conceptual models. After presenting the conceptual
models, some conclusions about these models and their applications are drown
Our Museum Special Initiative: An Evaluation
Our Museum: Communities and Museums as Active Partners was a Paul Hamlyn Foundation Special Initiative 2012 – 2016. The overall aim was to influence the museum and gallery sector to:* Place community needs, values and active collaboration at the core of museum and gallery work* Involve communities and individuals in decision-making processes* Ensure that museums and galleries play an effective role in developing community skills and the skills of staff in working with communitiesThis was to be done through facilitation of organisational change in specific museums and galleries already committed to active partnership with communities.Our Museum offered a collaborative learning process through which institutions and communities shared experiences and learned from each other as critical friends. Our Museum took place at a difficult and challenging time for both museums and their community partners. Financial austerity led to major cutbacks in public sector expenditure; a search for new business models; growing competition for funding; and organisational uncertainty and staff volatility. At the same time, the debate at the heart of Our Museum widened and intensified: what should the purpose of longestablished cultural institutions be in the 21st century; how do they maintain relevance and resonance in the contemporary world; how can they best serve their communities; can they, and should they, promote cultural democracy
Affective Sustainability. The Creation and Transmission of Affect through an Educative Process: An Instrument for the Construction of more Sustainable Citizens
Although for many years the debate on sustainability has focused on the generation of
critical thinking based on the dynamic balance between the economic, social and environmental
spheres, in the following text we propose to elaborate on the use of a eminently human condition,
such as the capacity to love and create an emotional attachment, whether with our environment or
our fellow men, as an initiator and main force for change to the building a more sustainable model
of development. To do so we shall begin from the concept coined by Adriana Bisquert in the 90s,
that is A ective sustainability, by analyzing it, delving into its possible definitions by means of the
development of the project for Environmental Education and Development called “Educating for a
more sustainable citizenship” undertaken by the Spanish NGO (non-governmental organization) or
ITACA Ambiente Elegido, and developed in the locality of Paterna de Rivera, Cádiz (Spain). This is a
practical and real example, which is used to establish a work educational methodology that enables
us to consider this concept as the real basis for an exportable and replicable work in a painstaking
search for the creation of a more sustainable city
