Book Description
The subject of this thesis is to study approximation algorithms for some network design problems in face of uncertainty. We consider two widely studied models of handling uncertainties - Robust Optimization and Stochastic Optimization. We study a robust version of the well studied Uncapacitated Facility Location Problem (UFLP). In this version, once the set of facilities to be opened is decided, an adversary may close at most [beta] facilities. The clients must then be assigned to the remaining open facilities. The performance of a solution is measured by the worst possible set of facilities that the adversary may close. We introduce a novel LP for the problem, and provide an LP rounding algorithm when all facilities have same opening costs. We also study the 2-stage Stochastic version of the Steiner Tree Problem. In this version, the set of terminals to be covered is not known in advance. Instead, a probability distribution over the possible sets of terminals is known. One is allowed to build a partial solution in the first stage a low cost, and when the exact scenario to be covered becomes known in the second stage, one is allowed to extend the solution by building a recourse network, albeit at higher cost. The aim is to construct a solution of low cost in expectation. We provide an LP rounding algorithm for this problem that beats the current best known LP rounding based approximation algorithm.

Book Description
In the face of ever more complex societal challenges, this book provides an essential new model for transforming the public sector and getting things done. Pandemics. Climate change. Refugee resettlement. Global supply chains. We face a new generation of complex problems that stretch across the public and private sectors and flow over organizational boundaries. To meet the moment, we need a fresh, new approach that strengthens institutions and government agencies by breaking free from organizational boxes and rigid, top-down leadership. As William D. Eggers, executive director of Deloitte's Center for Government Insights, and Donald F. Kettl, public management scholar, show in this indispensable book, we need a government of bridgebuilders who collaborate with partners—inside and outside government—to get the job done. These leaders manage horizontally instead of vertically; they see their role as connectors; and they identify which players have the assets needed to solve the unprecedented problems at hand. Each chapter examines one of the ten core principles of bridgebuilding and features practical tips and dynamic cases of how effective leaders have put each bridgebuilding principle to work. The book also includes a special section that helps government leaders create a hundred-day bridgebuilding plan. Throughout, Eggers and Kettl tell fascinating and instructive stories about some of today's bridgebuilders—federal, state, and local government leaders who transcend boundaries, partner across sectors, and get stuff done. Trusted and effective government has never been more important than today. Bridgebuilders provides a new model that current government decision makers—as well as young leaders who aspire to public service—can learn from and apply right now to transform government and restore public trust.

Book Description
This practical guide shows how to facilitate collaboration among diverse individuals and organizations to navigate complexity and create change in our interconnected world. The social and environmental challenges we face today are not only complex, they are also systemic and structural and have no obvious solutions. They require diverse combinations of people, organizations, and sectors to coordinate actions and work together even when the way forward is unclear. Even so, collaborative efforts often fail because they attempt to navigate complexity with traditional strategic plans, created by hierarchies that ignore the way people naturally connect. By embracing a living-systems approach to organizing, impact networks bring people together to build relationships across boundaries; leverage the existing work, skills, and motivations of the group; and make progress amid unpredictable and ever-changing conditions. As a powerful and flexible organizing system that can span regions, organizations, and silos of all kinds, impact networks underlie some of the most impressive and large-scale efforts to create change across the globe. David Ehrlichman draws on his experience as a network builder; interviews with dozens of network leaders; and insights from the fields of network science, community building, and systems thinking to provide a clear process for creating and developing impact networks. Given the increasing complexity of our society and the issues we face, our ability to form, grow, and work through networks has never been more essential.

Book Description
Fundamental environmental challenges such as climate change, resource depletion, and pollution are still widely relevant in today’s world. Many of these problems have been associated with the architecture, engineering, and construction industries due to the level of resources used in these professions. In recent years, many manufacturers in these fields have expressed the motivation to make necessary changes that would be beneficial to the environment. Despite this progress, there remains a lack of research and assessment on the methods to achieve environmental stability within these architectural fields. Examining the Environmental Impacts of Materials and Buildings provides emerging research exploring the theoretical and practical aspects of ecological performance within modern building design and materials-based construction. Featuring coverage on a broad range of topics such as life cycle assessment, material flows analysis, and sustainability, this book is ideally designed for architects, civil engineers, construction professionals, environmentalists, ecologists, business practitioners, scientists, policymakers, designers, researchers, and academicians seeking research on current trends in environmental performance within building design.
