Economic-based Distributed Resource Management and Scheduling for Grid Computing
Computational Grids, emerging as an infrastructure for next generation
computing, enable the sharing, selection, and aggregation of geographically
distributed resources for solving large-scale problems in science, engineering,
and commerce. As the resources in the Grid are heterogeneous and geographically
distributed with varying availability and a variety of usage and cost policies
for diverse users at different times and, priorities as well as goals that vary
with time. The management of resources and application scheduling in such a
large and distributed environment is a complex task. This thesis proposes a
distributed computational economy as an effective metaphor for the management
of resources and application scheduling. It proposes an architectural framework
that supports resource trading and quality of services based scheduling. It
enables the regulation of supply and demand for resources and provides an
incentive for resource owners for participating in the Grid and motives the
users to trade-off between the deadline, budget, and the required level of
quality of service. The thesis demonstrates the capability of economic-based
systems for peer-to-peer distributed computing by developing users'
quality-of-service requirements driven scheduling strategies and algorithms. It
demonstrates their effectiveness by performing scheduling experiments on the
World-Wide Grid for solving parameter sweep applications
Scattered Governance: A Typology for Torontoâs Business Improvement Areas
Business Improvement Areas (BIAs) - or Business Improvement Districts as they are known in the United States - are self-taxing local bodies that play an important role in urban governance. Toronto, which was the location of the first BIA in the world, has one of the highest number of BIAs in North America, yet little is known about how these bodies differ across the city. Using a mixed methodological approach that includes geographic information systems mapping, quantitative analysis, and semi-structured interview data, this chapter addresses this gap in knowledge by offering a typology of Toronto BIAs, looking at the metrics of size, walkability/transit score, budgets, and year of formation. The study concludes that there are four kinds of BIAs in Toronto scattered unevenly across the city: Big City Builders, Old Local Stewards, Big Industrial Powerhouses, and Emerging Small Centres. The paper sets out the unique attributes of each kind of BIA, some preliminary conclusions as to how Torontoâs BIA types differ from those in other jurisdictions, and points at the explosive creation of Emerging Small Centres BIAs following Toronto\u27s amalgamation
Evaluating Auction Mechanisms for the Preservation of Cost-Aware Digital Objects under Constrained Digital Preservation Budgets
Digital preservation is a field of research focused on designing strategies for maintaining digital objects accessible for general use in the coming years. Out of the many approaches to digital preservation, the present research article is a continuation work of a previously published article containing a proposal for a novel object-centered paradigm to address the digital preservation problem where digital objects share part of the responsibility for self-preservation. In the new framework, the behavior of digital objects is modeled to find the best preservation strategy. The results presented in the current article add a new economic constraint to the object behavior. Now, differently from the previous paper, migrations, copies and updates are not free to use, but subject to budget limitations to ensure the economic sustainability of the whole preservation system, forcing the now-called cost-aware digital objects for efficient management of available budget. The presented approach compares two auction-based mechanisms, a multi-unit auction and a combinatorial auction, with a simple direct purchase strategy as possible efficient behaviors for budget management. TiM, a simulated environment for running distributed digital ecosystems, is used to perform the experiments. The simulated results map the relation between the studied purchase models with the sustained quality level of digital objects, as a measure of its accessibility, together with its budget management capabilities. About the results, the best performance corresponds to the combinatorial auction model. The results are a good approach to deal with the digital preservation problem from a sustainable point of view and open the door to future implementations with other purchase strategies

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES
Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast
body of knowledge rooted in the history of human civilisation. These form the repository of the
wisdom of great works by thinkers of past and the present. The holdings of these institutions are
priceless heritage of the mankind as they preserve documents, ideas, and the oral and written
records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our
ancestors is the major responsibility of libraries. The past records constitute a natural resource
and are indispensable to the present generation as well as to the generations to come. Libraries
preserve the documentary heritage resources for which they are primarily responsible. Any loss of
such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage
becomes not only the academic commitment but also the moral responsibility of the
librarians/information scientists, who are in charge of these repositories.
The high quality of the papers and the discussion represent the thinking and experience of experts
in their particular fields. The contributed papers also relate to the methodology used in libraries
in Asia to provide access to manuscripts and cultural heritage. The volume discusses best practices
in Knowledge preservation and how to collaborate and preserve the culture. The book also deals with
manuscript and archives issues in the digital era.
The approach of this book is concise, comprehensively, covering all major aspects of preservation
and conservation through libraries. The readership of the book is not just limited to library and
information science professionals, but also for those involved in conservation, preservation,
restoration or other related disciplines. The book will be useful for librarians, archivists and
conservators.
We thank the Sunan Kalijaga University, Special Libraries Association- Asian Chapter for their
trust and their constant support, all the contributors for their submissions, the members of the Local
and International Committee for their reviewing effort for making this publication possible
Key Concepts in Public Archaeology
This book provides a broad overview of the key concepts in public archaeology, a research field that examines the relationship between archaeology and the public, in both theoretical and practical terms. While based on the long-standing programme of undergraduate and graduate teaching in public archaeology at UCLâs Institute of Archaeology, the book also takes into account the growth of scholarship from around the world and seeks to clarify what exactly âpublic archaeologyâ is by promoting an inclusive, socially and politically engaged vision of the discipline. Written for students and practitioners, the individual chapters provide textbook-level introductions to the themes, theories and controversies that connect archaeology to wider society, from the trade in illicit antiquities to the use of digital media in public engagement, and point readers to the most relevant case studies and learning resources to aid their further study
Designing Activist Spatial Experiences Using Mixed-Media Virtual Environments
This research investigated how to design âactivist spatial experiencesâ to communicate contemporary political narratives of under-resourced or misrepresented people. The research involved designing a prototype that was evaluated using experts testing and feedback. The innovative design solution used low-cost interactive and digital technology to create a mixed-media virtual environment. The findings successfully demonstrated significant embodied and affective spatial immersivity between viewers and the multimodal content, but also found challenges in navigation and interaction
