Policymakers, practitioners, and researchers frequently cite an increase in shocks around the world as a reason for focusing on resilience. But have shocks actually increased or become more severe and far-reaching? What does the landscape of shocks look like? Shocks are external, short-term deviations from long-term trendsdeviations that have substantial negative effects (which may be short-lived or long lasting) on peoples state of well-being, level of assets, livelihoods, safety, and ability to withstand future shocks. Many shocks are unexpected, but in some cases, such as drought or conflict, the shock may be expected year after year although the individual, community, or system lacks the resilience to prepare for or mitigate it. In other cases, such as climate change, the general shock could be expected but the effect on a particular individual, community, or area could be unexpected. This brief examines five types of shocksconflicts, natural disasters, climate change, food price volatility, and health crisesas they relate to food safety and agriculture. It assesses their frequency, severity, or both during the past few decades as part of a selective, nonsystematic review.

The equations describing the motion of a perfect fluid were first formulated by Euler in 1752. These equations were among the first partial differential equations to be written down, but, after a lapse of two and a half centuries, we are still far from adequately understanding the observed phenomena which are supposed to lie within their domain of validity. These phenomena include the formation and evolution of shocks in compressible fluids, the subject of the present monograph. The first work on shock formation was done by Riemann in 1858. However, his analysis was limited to the simplified case of one space dimension. Since then, several deep physical insights have been attained and new methods of mathematical analysis invented. Nevertheless, the theory of the formation and evolution of shocks in real three-dimensional fluids has remained up to this day fundamentally incomplete. This monograph considers the relativistic Euler equations in three space dimensions for a perfect fluid with an arbitrary equation of state. The author considers initial data for these equations which outside a sphere coincide with the data corresponding to a constant state. Under suitable restriction on the size of the initial departure from the constant state, he establishes theorems that give a complete description of the maximal classical development. In particular, it is shown that the boundary of the domain of the maximal classical development has a singular part where the inverse density of the wave fronts vanishes, signalling shock formation. The theorems give a detailed description of the geometry of this singular boundary and a detailed analysis of the behavior of the solution there. A complete picture of shock formation in three-dimensional fluids is thereby obtained. The approach is geometric, the central concept being that of the acoustical spacetime manifold.

Radical technological changes (so-called "technology shocks") frequently disrupt the competitive market structure. New entrants appear, industries need to be redefined, incumbents lose their positions or vanish completely. Fast moving industries - like the often quoted example of the semiconductor industry - have preferably been analyzed for these phenomena. But do the findings hold for industries with longer development cycles like the global machine tool industry? Here, multivariate analysis is used to find out what management needs to focus on in order to lead companies through the technology shocks. The research for this book builds on in-depth interviews with 100 experts and decision makers from the machine tool industry involved in technology shocks and statistical analysis of detailed quantitative surveys collected from 58 companies. In several instances the results challenge classical teaching of technology management. Adrian J. Slywotzky - US top selling business author and one of the most distinguished intellectual leaders in business - comments: "In Technology Shocks, Heinrich Arnold develops a very useful model for analyzing technology shocks, and for focusing on those factors that will enable a company to navigate through these shocks successfully, and repeatedly. Although this work is focused on technology, its thinking has useful implications beyond technology shocks. It provides ideas that managers can use to protect their firms when they are faced with any type of discontinuity, technology-based or not".

In Laos health shocks are more common than most other shocks and more concentrated among the poor. They tend to be more idiosyncratic than non-health shocks, and are more costly, partly because they lead to high medical expenses, but also because they lead to income losses that are sizeable compared with the income losses associated with non-health shocks. Health shocks also stand out from other shocks in the number of coping strategies they trigger: they are more likely than non-health shocks to trigger assistance from a nongovernmental organization and other households, dis-saving, borrowing, asset sales, an early harvest, the pawning of possessions, and the delaying of plans; by contrast, they are less likely to trigger assistance from government. Consumption regressions point to only limited evidence of households not being able to smooth consumption in the face of any shock. However, these results contrast with households' own assessments of the welfare impacts of shocks. The majority said they had to cut back consumption following a shock and that shocks considerably affected their welfare. Only health shocks are worse than a drought in terms of the likelihood of a family being forced to cut back consumption and in terms of the shock affecting a family's well-being "a lot." The poor are especially disadvantaged in terms of the greater damage that health shocks inflict on household well-being. Health shocks stand out too in leading to a loss of human capital: household members experiencing a health shock did not recover their former subjective health following the health shock, losing, on average, 0.6 points on a 5-point scale. The wealthier and better educated are better able to limit the health impacts of a health shock; the data are consistent with this being due to their greater proximity to a health facility.

This thesis presents a new strategy that unites qualitative and quantitative mass data in form of text news and tick-by-tick asset prices to forecast the risk of upcoming volatility shocks. Holger Kömm embeds the proposed strategy in a monitoring system, using first, a sequence of competing estimators to compute the unobservable volatility; second, a new two-state Markov switching mixture model for autoregressive and zero-inflated time-series to identify structural breaks in a latent data generation process and third, a selection of competing pattern recognition algorithms to classify the potential information embedded in unexpected, but public observable text data in shock and nonshock information. The monitor is trained, tested, and evaluated on a two year survey on the prime standard assets listed in the indices DAX, MDAX, SDAX and TecDAX.

This book provides an elementary introduction to one-dimensional fluid flow problems involving shock waves in air. The differential equations of fluid flow are approximated by finite difference equations and these in turn are numerically integrated in a stepwise manner, with artificial viscosity introduced into the numerical calculations in order to deal with shocks. This treatment of the subject is focused on the finite-difference approach to solve the coupled differential equations of fluid flow and presents the results arising from the numerical solution using Mathcad programming. Both plane and spherical shock waves are discussed with particular emphasis on very strong explosive shocks in air. This expanded second edition features substantial new material on sound wave parameters, Riemann's method for numerical integration of the equations of motion, approximate analytical expressions for weak shock waves, short duration piston motion, numerical results for shock wave interactions, and new appendices on the piston withdrawal problem and numerical results for a closed shock tube. This text will appeal to students, researchers, and professionals in shock wave research and related fields. Students in particular will appreciate the benefits of numerical methods in fluid mechanics and the level of presentation.

This paper uses a structural vector autoregression representation of the Mundell-Flemming model to analyze the determinants of movements in Sweden’s real exchange rate. It finds that, while (supply and demand) shocks account for over 60 percent of the forecast error variance, comparable to several Economic and Monetary Union (EMU) countries, demand shocks account for a higher fraction of these real shocks in Sweden than in those core countries. If real demand shocks result from controllable macroeconomic policies, the cost of relinquishing the exchange rate is no higher, and may be lower, for Sweden than for most core EMU countries.
