The volume scrutinizes publics and infrastructures not separately but in their constitutive interrelations and resonances. The contributions, originating in a range of disciplinary perspectives, share a praxeological approach, discussing historical and current processes of mediated cooperation in infrastructuring and making public(s) by tracing different forms of the production, design, and historic trajectories of various publics and infrastructures.
Economic development and social welfare depend on the existence of effective and efficient infrastructure systems, particularly in health, energy, transportation and water, many of which are developed and managed through Public-Private Partnerships (PPPs). However, empirical evidence suggests some pitfalls in the use of these PPP arrangements. This book addresses these issues, focusing on mostly three key questions: How to improve the robustness of the decision-making process leading to the option of PPP? How to improve contract management as the longest phase of the process? How can contracts be improved to accommodate uncertainty and avoid harmful renegotiations? The authors explore the concept of flexible contracts, the uncertainty modeling for improving the robustness of the decision-making process, and develop an overall framework for effective contract management, along with a comprehensive analysis of current renegotiation patterns. The ultimate goal is to improve the contractual performance, as well as the overall infrastructure management and social welfare. ​
Infrastructure has always had a privileged relationship to both expertise and the public in modern government. But in the early 21st century, this relationship is inflected in novel ways. The purposes public infrastructure was meant to serve-welfare, quality of life, economic development, and so on-persist. But they are often conceptualized differently, promoted by different agencies, and articulated through novel technological and collective relations. This issue of Limn explores new formations of infrastructure, publicness, and expertise.The contributions examine how new forms of expertise conceive the public and make claims in its name, how publics are making novel claims on experts (and claims to expertise), and how earlier norms and techniques of infrastructure provisioning are being adapted in the process.
Public–private partnerships (PPPs) are arrangements between government and private actors with the objective of providing public infrastructure, facilities and services. Three fundamental questions frame the use of PPPs at the local level: What do PPPs look like? What gives rise to the use of PPPs? And, what are the outcomes of PPPs? The articles in this book provide insightful answers to these questions. In addition, the contributions in the book identify lines of research that invite further investigation, namely: problems related to the degree of risk transfer; the challenges posed by renegotiation; and evaluation of PPPs’ results. The content of this book will be of interest for scholars, policy analysts, and policy makers. This book was published as a special issue of Local Government Studies.
Public-Private Partnerships for Infrastructure - Principles of Policy and Finance, Second Edition explains how public private partnerships are prepared, procured, financed, and managed from both the public- and private-sector perspectives. As the use of public private partnerships continues to develop world-wide, both in the area of public policy and private financing and contracting, the Second Edition of this leading textbook: Captures and explains the latest approaches, providing a comprehensive all-round guide for those on both the public- and private-sector sides of the table Emphasises a step-by-step approach within a comprehensive, cross-referenced format Includes clear explanations of PPP evaluation, structuring and financing concepts for the benefit of those new to the topic: no prior knowledge is assumed or required Provides detailed reference points for more experienced practitioners Draws from the authors’ experience and practice in PPP markets worldwide to provide a perspective on practical application of the key underlying principles Includes an extensive glossary of technical and financial terms used in the PPP sector Includes more technical information and a stronger legal perspective than other books Emphasizes a step-by-step approach within a comprehensive, cross-referenced format Expands and updates the historical backgrounds and political contexts of public-private partnerships
The introduction of public key cryptography (PKC) was a critical advance in IT security. In contrast to symmetric key cryptography, it enables confidential communication between entities in open networks, in particular the Internet, without prior contact. Beyond this PKC also enables protection techniques that have no analogue in traditional cryptography, most importantly digital signatures which for example support Internet security by authenticating software downloads and updates. Although PKC does not require the confidential exchange of secret keys, proper management of the private and public keys used in PKC is still of vital importance: the private keys must remain private, and the public keys must be verifiably authentic. So understanding so-called public key infrastructures (PKIs) that manage key pairs is at least as important as studying the ingenious mathematical ideas underlying PKC. In this book the authors explain the most important concepts underlying PKIs and discuss relevant standards, implementations, and applications. The book is structured into chapters on the motivation for PKI, certificates, trust models, private keys, revocation, validity models, certification service providers, certificate policies, certification paths, and practical aspects of PKI. This is a suitable textbook for advanced undergraduate and graduate courses in computer science, mathematics, engineering, and related disciplines, complementing introductory courses on cryptography. The authors assume only basic computer science prerequisites, and they include exercises in all chapters and solutions in an appendix. They also include detailed pointers to relevant standards and implementation guidelines, so the book is also appropriate for self-study and reference by industrial and academic researchers and practitioners.
There is a growing body of knowledge revealing a sweeping array of connections between public health and green infrastructure – but not until now have the links between them been brought together in one comprehensive book. Green Infrastructure and Public Health provides an overview of current research and theories of the ecological relationships and mechanisms by which the environment influences human health and health behaviour. Covering a broad spectrum of contemporary understanding, Coutts outlines: public health models that explicitly promote the importance of the environment to health ways in which the quality of the landscape is tied to health challenges of maintaining viable landscapes amidst a rapidly changing global environment This book presents the case for fundamental human dependence on the natural environment and creates a bridge between contemporary science on the structure and form of a healthy landscape and the myriad ways that a healthy landscape supports healthy human beings. It presents ideal reading for students and practitioners of landscape architecture, urban design, planning, and health studies.
The contributors to Signal Traffic investigate how the material artifacts of media infrastructure--transoceanic cables, mobile telephone towers, Internet data centers, and the like--intersect with everyday life. Essayists confront the multiple and hybrid forms networks take, the different ways networks are imagined and engaged with by publics around the world, their local effects, and what human beings experience when a network fails. Some contributors explore the physical objects and industrial relations that make up an infrastructure. Others venture into the marginalized communities orphaned from the knowledge economies, technological literacies, and epistemological questions linked to infrastructural formation and use. The wide-ranging insights delineate the oft-ignored contrasts between industrialized and developing regions, rich and poor areas, and urban and rural settings, bringing technological differences into focus. Contributors include Charles R. Acland, Paul Dourish, Sarah Harris, Jennifer Holt and Patrick Vonderau, Shannon Mattern, Toby Miller, Lisa Parks, Christian Sandvig, Nicole Starosielski, Jonathan Sterne, and Helga Tawil-Souri.
Deregulation, privatization and marketization have become the bywords for the reforms and debates surrounding the public sector. This major book is unique in its comparative analysis of the reform experience in Western and Eastern Europe, Australia, New Zealand and Canada. Leading experts identify a number of key factors to systematically explain the similarities and differences, map common problems and together reflect on the future shape of the public sector, exploring significant themes in a lively and accessible way.
"Policy-makers often call for expanding public spending on infrastructure, which includes a broad range of investments from roads and bridges to digital networks that will expand access to high-speed broadband. Some point to near-term macro-economic benefits and job creation, others focus on long-term effects on productivity and economic growth. This volume explores the links between infrastructure spending and economic outcomes, as well as key economic issues in the funding and management of infrastructure projects. It draws together research studies that describe the short-run stimulus effects of infrastructure spending, develop new estimates of the stock of U.S. infrastructure capital, and explore the incentive aspects of public-private partnerships (PPPs). A salient issue is the treatment of risk in evaluating publicly-funded infrastructure projects and in connection with PPPs. The goal of the volume is to provide a reference for researchers seeking to expand research on infrastructure issues, and for policy-makers tasked with determining the appropriate level of infrastructure spending"--
