This paper first outlines the key stylized facts about changes in inflation dynamics in recent years: 1) inflation persistence has declined, 2) the Phillips curve has flattened, and 3) inflation has become less responsive to other shocks. These changes in inflation dynamics are interpreted as resulting from an anchoring of inflation expectations as a result of better monetary policy. The paper then goes on to draw implications for monetary policy from this interpretation, as well as implications for inflation forecasts.

In urban analytics, 'crowding' implies the spatiotemporal distributional unevenness of people's stays and flows in middle-scale urban spaces, and has since become an emerging keyword, attracting not only practical interests but also research interests, especially in the current IoT devised downtown. This book presents a collection of papers on a series of exploratory studies on the rise and fall of downtowns (Downtown Dynamics), which the author's group has been working on with the aim of constructing an artificial society that contributes to the planning and management of crowds by developing Agent-Based Social Simulation (ABSS). In particular, the book includes (1) an analysis of 20 years' worth of survey data on visitors' shopping-around behavior for Osu district in Nagoya city, as a representative Japanese downtown, (2) correlation analyses of spatial distributions between Visibility Graph Analysis (VGA) as a "visibility index" and crowding in middle scale urban spaces, (3) agent modeling of visitors' shopping-around behavior and construction of the Downtown Dynamics Model as an artificial society, and (4) modeling of the vision-driven agent as a "crowd generator" and its applicability to spatial design and sign layout in urban spaces. The book also includes a novel research program derived from complexity system science that provides new approaches to Agent-Based Modeling (ABM), social simulation, regional sciences, geo-informatics, and urban planning studies for researchers and graduate students, as well as planning scientists and practitioners such as town managers and planners who are concerned with downtown revitalization. .
"Humans have moved organisms around the world for centuries, but it is only relatively recently that invasion ecology has grown into a mainstream research field. This book examines both the spread and impact dynamics of invasive species, placing the science of invasion biology on a new, more rigorous, theoretical footing. Furthermore, it proposes a concept of adaptive networks as the foundation for future research. Biological invasions are considered not as simple actions of invaders and reactions of invaded ecosystems, but as co-evolving complex adaptive systems with emergent features of network complexity and invasibility. Invasion Dynamics focuses on the ecology of invasive species and their impacts in recipient social-ecological systems. It not only discusses key advances and challenges within the traditional domain of invasion ecology, but introduces approaches, concepts, and insights from many other disciplines such as complexity science, systems science, and ecology more broadly. It will be of great value to invasion biologists analysing spread and/or impact dynamics as well as other ecologists interested in spread processes or habitat management."--

Written in clear, concise language, Felson explains how one crime is linked to another and how illegal behaviour feeds off legal activities in everyday life. He considers how offenders find crime opportunities, adapt to new conditions, and cooperate with one another while drawing resources from the larger community
