Most policy analyses of both short-term and long-term disasters focus on aggregate impacts of their costs and the benefits of policy remedies. Distributional considerations relating to the costs of these disasters and the benefits of their risk management, however, are very important in many cases. This article examines two broad categories of cases in terms of distributional considerations. The first category is where transboundary considerations strongly affect risk governance, as in the case of climate change. The second relates to ordinary, short-term disasters, which include fewer, but still important, transboundary issues. Climate change policy requires information regarding the distribution of impacts and policy responses across countries because it is a global *** disasters involve transboundary considerations much less frequently, so the attention typically shifts to the distribution of benefits and costs within a jurisdiction. In both cases distributional information is needed to evaluate the equity of policies and to provide information for public participation in the policy process. This article offers modeling and policy approaches to address these issues.

Harvesting incident photons is the first step in a photo-induced process such as photocatalysis, photovoltaics or photodetection, which crucially governs the process performance. Unfortunately,extensive energy losses are observed in this step due to severe surface reflections and limited optical paths of the shortwavelength light [1]. Thus,

Monoclinic paracetamol (PA) is notorious as a poorly compactible model drug. Polyvinylpyrrolidone (PVP) is a polymer that can act as an effective binder to improve the mechanical properties of PA. It is surprising however that the role of mixing conditions on the physicochemical and mechanical properties of PA-PVP mixtures has not been reported previously. The results of this work showed that PA-PVP mixtures containing 5%(w/w) PVP prepared using high energy mixing conditions had considerably smaller particle size distributions and higher cohesivities than mixtures prepared using low energy mixing conditions. Solid-state analysis did not detect any change in the monoclinic crystalline form of PA after mixing with PVP. The following rank order of tabletability for PA-PVP mixtures was obtained according to the mixing condition: low shear-medium shear< dry high shear< wet high shear< high-speed homogenization. A higher level of hydrogen bonding was detected in the mixtures prepared via high energy mixing conditions than in those prepared using low energy mixing conditions. Mixing is therefore a critical process that needs to be optimized during the preparation of in teractive mixtures for tableting.

Modeling the economic consequences of disasters has reached a high level of maturity and accuracy in recent years. Methods for providing reasonably accurate rapid estimates of economic losses, however, are still limited. This article presents the case for “reduced-form” models for rapid economic consequence estimation for disasters, and specifies and statistically estimates a regression equation for property damage from significant U.S. earthquakes. Explanatory variables are of two categories:(1) hazard-related variables pertaining to earthquake characteristics;and(2) exposure-related variables pertaining to socioeconomic conditions. Comparisons to other available earthquake damage estimates indicate that our Reduced-Form Model yields reasonably good results, including several statistically significant variables that are consistent with a priori hypotheses. The article concludes with a discussion of how the research can be enhanced through the collection of data on additional variables, and of the potential for the extension of the reduced-form modeling approach to other hazard types.
