Complexity And Resilience Rating

With all likelihood high complexity is the most evident and dramatic characteristic of not just the economy; it is also the hallmark of our lives. In a complex economy conventional risk management, risk rating and business intelligence technologies are becoming dangerously outdated. The tools and solutions presented in this book have been architectured specifically for turbulence and for a complex economy dominated by shocks, destabilizing events and instability. In particular, the book proposes a new rating model based on resilience, the capacity to withstand such shocks, beyond the increasingly irrelevant but still popular idea of Probability of Default (PoD). Moreover, it is shown how in an interconnected economy rating single companies provides little insight as to its state of health and sustainability and how large-scale systemic analyses of ecosystems of corporations can provide new knowledge and new insights for the global investor. Finally, new approaches to asset allocation and portfolio design based on complexity and resilience are introduced.

One focus area in data management research is to understand how changes in the data can affect the output of a view or standing query. Example applications are explaining query results and propagating updates through views. In this thesis we study the complexity of the Resilience problem, which is the problem of finding the minimum number of tuples that need to be deleted from the database in order to change the result of a query. We will see that resilience is closely related to the well-studied problems of deletion propagation and causal responsibility, and that analyzing its complexity offers important insight for solving those problems as well. Our contributions include the definition of the concept of triads for conjunctive queries, which is a crucial tool on our analysis, and the characterization of a NP versus P dichotomy for the resilience problem considering the class of conjunctive queries without self-joins. Moreover, this result allowed us to show dichotomies for the same class of queries for both deletion propagation with source side-effects and causal responsibility problems. We also completely characterize how the presence of functional dependencies can change the complexity of such problems. The class of conjunctive queries with self-joins is far richer and more complicated than the self-join-free ones. Therefore we focus on binary queries without variable repetition, which are queries formed by unary or binary relations only and each atom has only one occurrence of any variable. For this restricted case, we identify three main query structures that help us identify complexity: chains, permutations and confluences. Using those we are able to characterize classes of queries for which resilience is NP-complete and some for which it is P.

Engineering within Ecological Constraints presents a rare dialogue between engineers and environmental scientists as they consider the many technical as well as social and legal challenges of ecologically sensitive engineering. The volume looks at the concepts of scale, resilience, and chaos as they apply to the points where the ecological life support system of nature interacts with the technological life support system created by humankind. Among the questions addressed are: What are the implications of differences between ecological and engineering concepts of efficiency and stability? How can engineering solutions to immediate problems be made compatible with long-term ecological concerns? How can we transfer ecological principles to economic systems? The book also includes important case studies on such topics as water management in southern Florida and California and oil exploration in rain forests. From its conceptual discussions to the practical experience reflected in case studies, this volume will be important to policymakers, practitioners, researchers, educators, and students in the fields of engineering, environmental science, and environmental policy.

This book interprets how ancient civilizations responded to various stresses, including environmental change, warfare, and the fragmentation of political institutions. It focuses on what happened during and after the decline of once powerful regimes, and posits that they experienced social resilience and transformation instead of collapse.

Resilience has become a central concept in government policy understandings over the last decade. In our complex, global and interconnected world, resilience appears to be the policy ‘buzzword’ of choice, alleged to be the solution to a wide and ever-growing range of policy issues. This book analyses the key aspects of resilience-thinking and highlights how resilience impacts upon traditional conceptions of governance. This concise and accessible book investigates how resilience-thinking adds new insights into how politics (both domestically and internationally) is understood to work and how problems are perceived and addressed; from educational training in schools to global ethics and from responses to shock events and natural disasters to long-term international policies to promote peace and development. This book also raises searching questions about how resilience-thinking influences the types of knowledge and understanding we value and challenges traditional conceptions of social and political processes. It sets forward a new and clear conceptualisation of resilience, of use to students, academics and policy-makers, emphasising the links between the rise of resilience and awareness of the complex nature of problems and policy-making.

Alongside well explained scientific theory, each chapter contains dramatic, real-life stories of people from frontline services, elite sports, and everyday survivors who learned to thrive in high pressure, demanding, and often deadly situations. You'll discover how resilience isn’t just the ability to tough it out; it's dependent upon an interconnected set of skills, techniques, creative processes, and new understandings of how we think, act, and interact with our environments and each other. If you or someone you care about experiences unwanted stress, anxiety, decision fatigue, overwhelm, or burnout, by applying the step-by-step techniques in this book, you'll learn to develop resilience, clarity, improved energy, wellbeing, and overall performance. You'll also learn: There's no such thing as an inherently stressful situation, workplace, or event. How to appreciate and benefit from the hidden information in your unconscious signals and intuitions How to adapt your decision making to meet the challenges of uncertainty, from the complicated and complex, to the outright chaotic When to define your limits and 'line in the sand' so that you never expose yourself to unmanageable risk or potential burnout What is it to, 'Know Thyself', through techniques that change perspective and bring clarity even in uncertain, turbulent times Techniques that can be easily taught to people you care about Lifelong resilience and being at your best is available to each of us, no matter what life throws at you. Resilience By Design was derived from the experiences of hundreds of people on the frontline of emergency services, defense, Olympic level sports, business, art, science, and many other areas of expertise—from firefighters and paramedics to social workers and athletes. This book is written for students and teachers, parents and children, caregivers and patients, athletes and coaches, managers and employees, entrepreneurs, and fortune 500 CEOs, and anyone who wishes to know how to survive and thrive in an ever more complex and turbulent world.

Increasingly, cracks are appearing in the capacity of communities, ecosystems, and landscapes to provide the goods and services that sustain our planet's well-being. The response from most quarters has been for "more of the same" that created the situation in the first place: more control, more intensification, and greater efficiency. "Resilience thinking" offers a different way of understanding the world and a new approach to managing resources. It embraces human and natural systems as complex entities continually adapting through cycles of change, and seeks to understand the qualities of a system that must be maintained or enhanced in order to achieve sustainability. It explains why greater efficiency by itself cannot solve resource problems and offers a constructive alternative that opens up options rather than closing them down. In Resilience Thinking, scientist Brian Walker and science writer David Salt present an accessible introduction to the emerging paradigm of resilience. The book arose out of appeals from colleagues in science and industry for a plainly written account of what resilience is all about and how a resilience approach differs from current practices. Rather than complicated theory, the book offers a conceptual overview along with five case studies of resilience thinking in the real world. It is an engaging and important work for anyone interested in managing risk in a complex world.

Presence-Based Leadership is founded on this liberating premise: leaders' most crucial and complex challenges, rather than being obstacles, are actually doorways for becoming precisely the leader that current conditions require. Here is a rich field guide to the territory of complexity, and how leaders can navigate it with leading-edge approaches that generate clarity, resilience, and results that actually matter. Silsbee's new book is his most expansive. A master of integration, he seamlessly weaves fields as disparate as complexity, leadership and adult development theory, mindfulness, and interpersonal neurobiology into a deeply human exploration of how leaders can bring the fullness of their humanity to the most intractable challenges they face. His immensely pragmatic approach grounds new perspectives with intimate real-world examples. He offers specific, field-tested experiments and practices that invite the reader into discovery and application. This is a radically new and integrated approach to leadership, through which leaders can tap the creativity and resourcefulness of their internal complexity in order to meet a complex world. Through cultivating an embodied leadership presence, readers will become more dynamic shapers of the context in which they lead, and a creative force for what matters in a fractured and dynamic world. Presence-Based Leadership is the third and final volume in Doug Silsbee's groundbreaking and influential trilogy on coaching and leadership.
